BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to saddle type vehicles and, more particularly, to a speed change controller for saddle-type vehicle.

2. Description of the Related Art

Conventionally, it is usual in vehicles that a driver's speed change device is mechanically and directly transmitted to a transmission by the use of a link, a rod, or wire to perform speed change operation. In recent years, however, there is proposed to adopt a shift actuator making use of an electric motor or the like to perform speed change operation for the purpose of making speed change operation by a driver easier. For example, JP-A-2001-050389 is as an example of such a shift actuator.

However, the above-referenced publication includes only a description to the effect that instructions of speed change for electrically-driven speed change control may be input into a control unit by a foot-moving type speed change pedal, and does not describe any concrete means for execution of such instructions of speed change. Accordingly, there remains a need for a speed change controller suited to manipulation by a foot.

“Motorcycle” referred to in the specification of the present application means a motorcycle, includes a bicycle with a motor (motorbike), scooter, and specifically means a vehicle capable of turning with a vehicle body inclined. Accordingly, “motorcycle” includes three-wheeler, four-wheeler (or more), in which at least one of a front wheel and a rear wheel comprises two or more wheels and which is three and four in number of tires. Also, “motorcycle” is not limited to motorcycles but applicable to other vehicles, which can make use of the effect of the invention. “Motorcycle” is applicable to, for example, a so-called saddle-ride type vehicle including four-wheel buggy (ATV (all-terrain vehicle)) and snowmobile.

“Saddle-type vehicle” widely includes vehicles assuming the same ride configuration as or similar to that of a motorcycle.

Also, “operation part” of a saddle-type vehicle disclosed herein can include a part (for example, a shift pedal in a motorcycle) directly manipulated by a foot, and a part (that is, a part indirectly manipulated on the basis of manipulation of a foot) linking with the former part to operate interlocking with the motion of the former part. Accordingly, the part directly manipulated by a foot included in the operation part and the part indirectly manipulated on the basis of manipulation of a foot, both the parts being included in the manipulating part, can be arranged in different regions of a vehicle while interlocking mutually by a link member.

While preferred embodiments of a speed change controller (typically, a device being electrically driven to exercise speed change control) for saddle-type vehicles will be described below with reference to the drawings, it is not intended that the invention is limited to such illustrated examples.

First, a first embodiment of a speed change controller disclosed herein will be described with reference toFIGS. 1 to 5.FIG. 1is a side view showing an outward appearance of a motorcycle1being a typical example of a saddle-ride type vehicle.

As shown inFIG. 1, the motorcycle1according to the embodiment is a sport type motorcycle1provided with a large-sized cowling2, and generally comprises a front wheel3, a rear wheel4, a handle5, a fuel tank6, and a seat7. An engine12can be supported by a vehicle body frame10and can be arranged below the fuel tank6and the seat7. In the illustrated embodiment, a unit100(referred below to as “operation unit100”), which comprises a detection mechanism of a speed change controller according to the illustrated embodiment, is arranged in a state of being supported on the vehicle body frame on a left side (specifically, a neighborhood of a left foot, which performs speed change operation) as viewed from a driver (referred below to as “rider”) in a riding state. Details of the operation unit100will be described below.

A general transmission (not shown) can be arranged in an engine casing14of the engine12. The transmission can be a general, so-called dog clutch type transmission and can have, for example, four to six number of speeds. Motive power from a crankshaft of the engine12can be transmitted to a main axle and then transmitted to drive axles via gears and dogs of the respective number of speeds.

Speed change of the transmission can be performed by a speed change mechanism20of the speed change controller according to the illustrated embodiment. That is, as shown in the illustrated embodiment ofFIG. 2, the speed change mechanism20comprises a shift fork22provided slidably on a slide rod21to regularly move slide gears of the transmission. Also, a shift cam24cant be provided rotatably to slide the shift fork22.

A cam groove24A can be formed on a periphery of the shift cam24. The cam groove24A can be formed to be shaped as shown inFIG. 3and the shift fork22slides along the cam groove24A.

Also, the shift cam24can be rotated via a ratchet mechanism27upon rotation of a shift shaft23. The ratchet mechanism27can rotate the shift fork22by a uniform interval (angle) to regularly move the shift fork22and can have a ratchet function in both forward and backward directions to effect speed change one stage by one stage. A shift arm25of the ratchet mechanism27transmits rotation of the shift shaft23to the shift cam24and simultaneously restricts a stroke of the shift shaft23to prevent overrun of the shift cam24. Also, a stopper plate26of the ratchet mechanism27can serve to fix the shift cam24to a predetermined position.

The shift shaft23can be turned in a predetermined direction by a driving force of a shift actuator23B, a signal from the operation unit (detection mechanism)100described later can be inputted into an engine control unit (ECU) (depiction of which is omitted), and a signal from the engine control unit can drivingly control the shift actuator23B. In addition, a detailed construction of the speed change mechanism may be the same as that of a conventional motorcycle.

Subsequently, the operation unit (detection mechanism)100according to the illustrated embodiment will be described in detail with reference toFIGS. 4 and 5.

In the illustrated embodiment, the operation unit100comprises a base plate102corresponding to “base” detachably mounted to the vehicle body frame10(or the engine casing14in another embodiment). The base plate102can be a substantially rectangular-shaped plate and can be mounted through mount holes105A to105D in four locations in total by screws (not shown) as shown inFIG. 4. The mount holes66acan be a little larger in diameter than the thread diameter. Thereby, positional adjustment relative to an engine casing14is made possible.

Mounted to the base plate102can be an operation part101, which can be operated by a foot for speed change. Also, formed on the base plate102can be a foot rest mount103, to which a foot rest9affording placing a rider's left foot thereon is pivotally mounted.

The operation part101can comprise a shift pedal110corresponding to a moving part in the embodiment. The shift pedal110can comprise an arm portion112, of which one end112A can be mounted pivotally to an inner surface side (e.g., a side facing a vehicle body). The same can be applied in the base plate102and a pedal portion114being that portion, which is mounted to the other end112B of the arm portion112can bee manipulated directly by a foot (a tip toe). Specifically, as shown in the illustrated embodiment ofFIGS. 4 and 5, the end112A of the arm portion112of the shift pedal110is mounted to a boss104of the base plate102in the vicinity of the foot rest9(that is, the foot rest mount103) by a screw member108to freely turn (e.g., being able to swing in two vertical directions) about the screw member108. Also, a pedal portion (pushed portion)114applied by a load from a foot can be provided substantially horizontally on the tip end112B of the shift pedal110(the arm portion112).

A detection unit120according to the illustrated embodiment can be provided on an outer surface side of the base plate102. That is, the base plate102can comprise a sensor, for example, a potentiometer (e.g., a rotation sensor or an angle sensor, which is composed of a potentiometer having a variable resistance element)122, which comprises a detection unit that detects that the shift pedal (moving part)110is moved a predetermined amount or more by manipulation of a foot. A sensor body123of the sensor122is fixed to the base plate102. A turning plate124can be mounted to the sensor body123and can be configured to turn. The turning plate124can be turned whereby movement (turning) of the moving part in a predetermined direction can be detected. A detection signal can be transmitted to the engine control unit (ECU).

The turning plate124can be formed with a latch notch125as shown inFIGS. 4 and 5. Inserted into the latch notch125can be a latch pin116, which can be protrusively provided on the shift pedal110. With such construction, when the shift pedal110is turned, the turning plate124can be turned via the latch pin116.

Also, in the illustrated embodiment, on an inner surface side of the base plate102can be provided spring, which can be in the form of a pine-needle shaped spring (e.g., as shown in the figure, a spring made of a metallic rod, of which a central portion is wound several turns and an angle between both straight ends of which is an acute angle)131, which acts as “return mechanism” to return the shift pedal110to a predetermined neutral position.

The pine-needle shaped spring131can comprise a pair of rods (straight ends)131A,131B to generate spring elasticity. Interposed between the pair of rods131A,131B can be a part (referred below to as “push portion112D”) of the arm portion112of the shift pedal110and a latch piece109A of a retainer109. As shown inFIG. 5, the retainer109can be fixed to the boss104of the base plate102.

In addition, the push portion112D can be formed on a bent part of the arm portion112of the shift pedal to be the same in width as other portions as shown inFIG. 5.

As described above, according to the illustrated embodiment, the moving part (shift pedal), the detection unit, and the return mechanism of the operation part are mounted to the base plate102to form an integral or single operation unit, so that the operation unit can be mounted integrally or as a group and detachably to the vehicle body frame10(or the engine casing14). Therefore, the operation unit can contribute to an improvement in productivity of motorcycles.

Also, in the illustrated embodiment, two stopper pins106,107can be mounted to the base plate102. More specifically, as shown inFIGS. 4 and 5, the ascent stopper pin106can be mounted in a position, in which it abuts against an upper edge of the shift pedal110to be able to stop turning thereof when the shift pedal110is moved (turned) a predetermined amount upward as indicated by a two-dot chain line inFIG. 4. On the other hand, as shown inFIG. 4, the descent stopper pin107can be mounted in a position, in which it abuts against a lower edge of the shift pedal110to be able to stop turning thereof when the shift pedal110is moved (turned) a predetermined amount downward as indicated by a dashed line inFIG. 4.

In the illustrated embodiment, also provided on the base plate102can be a plunger160that comprises an operating force changing mechanism. As shown inFIG. 5, a coil spring162can be inserted into a cylindrical-shaped body of the plunger160. Mounted at a tip end of the plunger160is a moving ball164connected to the spring162. The moving ball164can be supported by the spring162such that when the moving ball164is pushed axially of the cylindrical-shaped body with a predetermined force or more, the spring162yields to the push force to contract with the result that the moving ball164retreats into the cylindrical-shaped body. On the other hand, when such push disappears, the spring162is elongated by elasticity and the moving ball164returns to an original position (seeFIG. 5) at the tip end of the plunger160.

On the other hand, insertion grooves118can be formed in two locations on the shift pedal110to correspond to the plunger160and to comprise the operating force changing mechanism. Specifically, the insertion grooves118can be formed in those positions to realize insertion of the moving ball164at the tip end of the plunger160into the insertion groove118when the shift pedal110is manipulated by a foot to turn (swing) vertically from the predetermined neutral position (position indicated by solid lines) inFIG. 4to move to positions indicated by the dashed line and the two-dot chain line (respectively, referred below to as “shift-down bodily sensation signal generating position” and “shift-up bodily sensation signal generating position”).

That is, in the predetermined neutral position and in a position therearound, the moving ball164comes into pressure contact with a wall surface of the shift pedal110(the arm portion112), and such pressure applies a predetermined torque on a foot (that is, a left foot operating a shift change) operating the shift pedal. On the other hand, when the shift pedal110moves to the shift-down bodily sensation signal generating position or the shift-up bodily sensation signal generating position, the moving ball164is inserted into the insertion groove118. At the time of such insertion, torque required for operative movement of the shift pedal110is momentarily changed and further torque is momentarily changed when the moving ball164is once fixed in the insertion groove118. Such change is transmitted as bodily sensation signal (that is, a signal can be perceived by sensation of the body (e.g., here, a foot). The same is applied below.) to a rider. Specifically, such torque change is perceived as feeling of click through a foot's sensation by a rider.

An explanation will be given to function and effect, which can be produced as a result of the construction of the embodiment described above at the time of shift change.

First, in order to change a transmission in speed, a rider can turn (swing) the shift pedal110upward or downward with a foot until the arm portion112of the shift pedal110abuts against the respective stopper pins106,107.

At this time, one131A of the rods is pushed by the push portion112D of the shift pedal110to be elastically deformed. When a manipulating force on the shift pedal110by a foot is released, the shift pedal110is returned to the neutral position (predetermined position) indicated by solid lines inFIG. 4by an elastic force of the rod131A. In addition, as described above, when the shift pedal110comes to the position (shift-down bodily sensation signal generating position) indicated by the dashed line or the position (shift-up bodily sensation signal generating position) indicated by the two-dot chain line inFIG. 4, feeling of click is gotten by the operating force changing mechanism (plunger160) constructed in a manner described above.

Also, turning of the shift pedal110causes the turning plate124to turn via the latch pin116. At this time, it is detected by the sensor122that the shift pedal110has been turned in a predetermined direction, and its signal is transmitted to the engine control unit. According to the illustrated embodiment, output of a detection signal from the sensor122and timing, in which feeling of click is gotten, are synchronized with each other. Thereby, a rider can perceive the start of speed change control processing through the feeling of click by sensation of a foot although the speed change operation is performed by a foot as compared with a hand.

Then the shift actuator23B is operated by a signal from the engine control unit and the shift shaft23(FIG. 2) is turned in a predetermined direction.

When the shift shaft23is turned in this manner, the shift cam24can be rotated via the ratchet mechanism27in a predetermined direction and the shift fork22is guided by the cam groove24A to slide in a predetermined direction. Thereby, the slide gears of the transmission can be moved to bring about predetermined dog release and dog locking.

In addition, generally, when the number of speeds is decreased (perform shift-down), the shift pedal110is moved (turned) downward. On the other hand, when the number of speeds is increased (perform shift-up), the shift pedal110is turned upward.

With such arrangement, it is possible to readily perform shift operation with the same feeling of manipulation as conventional arrangement since manipulation of the shift pedal110by a foot is detected and the actuator is operated in an arrangement, in which a shift actuator is used to perform speed change operation.

Also, according to the embodiment, it is not necessary to connect the shift pedal110to the shift shaft23through a mechanical linkage unlike a conventional arrangement and the base plate102, the shift pedal110, the sensor122, etc. constitute an integral or combined operation unit100. Therefore, it is possible to readily perform mounting to the vehicle body frame10(or the engine casing14) at the time of production. That is, it is possible to readily mount the base plate102in a predetermined position.

Also, since those members, which constitute the operation part101such as the shift pedal110, the sensor122, etc. and the detection unit120, are made integral or coupled together as a unit, it is possible to readily adjust the sensor122and other equipments even before the operation unit100, etc. are mounted to a vehicle side (the vehicle body frame10, the engine casing14, etc.).

Also, the return mechanism (specifically, the pine-needle shaped spring131) to return the shift pedal110to a predetermined position (neutral position) can be provided to be made integral or coupled together with the operation unit100. Owing to this, it is possible to further improve productivity (in particular, assembling of parts).

Since the operation unit100according to the illustrated embodiment can be detachably and integrally mounted or mounted as a unit to a vehicle, the workability of arrangement is favorable and even in the case where the shift pedal110is not connected to the shift shaft23through a linkage like a conventional arrangement, it can be readily returned to the neutral position.

Also, since the shift pedal110(that is, a moving part) and a potentiometer68(that is, a detection unit) are made integral together or combined together in a unit, detection to a certain extent is possible in spite of a position, in which the operation unit65is mounted to a vehicle. In other words, positional regulation of the shift pedal110can be readily performed according to a user's (rider's) favorite by changing a position of the operation unit100.

Also, since parts manipulated by a foot are mounted to the base (the base plate102) together, the detection mechanism can be improved in stiffness.

A detection mechanism (operation unit)200, according to a second embodiment, of a speed change controller disclosed herein will be described with reference toFIG. 6 to 10. The detection mechanism200according to this illustrated embodiment is configured such that a support plate221comprising a base mounting portion thereon and a detection unit220is arranged on a base plate202mounted to the vehicle body frame10to afford positional regulation.

More specifically, as shown inFIG. 8, the support plate221together with a shift pedal (arm portion)210can be mounted pivotally to the base plate202by a single a screw member208. Specifically, like the first embodiment, an end212A of the shift pedal (arm portion)210can be mounted to a boss204of the base plate202by the screw member208in the vicinity of a foot rest9(that is, a foot rest mount203) to freely turn (specifically, being able to swing in two vertical directions). That is, the shift pedal can be mounted to be able to swing in two directions (here, a vertical direction) in the same manner as in general motorcycles. Also, the shift pedal210can be rotated an appropriate amount about the screw member208in either direction to be regulated in position and angle relative to a vehicle as described later.

A slot228can be formed on an end of the support plate221. The slot228can be open-shaped and can correspond to an arcuate shape about the screw member208. A mount bolt229can extend through and can be arranged in the slot228. The mount bolt229can be threaded into a predetermined mount hole provided in the base plate202whereby the support plate221is fixed in a predetermined position and at a predetermined angle.

As shown inFIGS. 6 and 7, a pair of shift pedal (detection) switches222,223, which can form a “detection unit” in the illustrated embodiment can be arranged in positions close to both sides of the shift pedal210on the support plate221. As a result of providing the shift pedal (detection) switches222,223in such positions, the shift pedal110is turned (moved) in either sense in a vertical direction from a predetermined reference position (neutral position) to abut against either of the shift pedal switches222,223, so that contact portions222A,223A of the switches222,223are pressed and pushed in whereby a switch ON state comes out. Here, when the shift pedal210is pushed up upward by a foot, the switch222thus abutted is a shift-up detection switch222, and when the shift pedal210is pushed down upward by a foot, the switch223thus abutted is a shift-down detection switch223. In addition, as apparent from the figure, according to the embodiment, the switches222,223can also function as stopper that restricts excessive movement (turning) of the shift pedal210.

A return mechanism230can be provided on a speed change controller according to the illustrated embodiment in the same manner as in the first embodiment. That is, a pine-needle shaped spring231can be provided on the shift pedal210as shown inFIG. 8. The pine-needle shaped spring231can comprise a pair of rods (straight ends)231A,231B to generate spring elasticity. Interposed between the pair of rods231A,231B can be a push portion212D protrusively provided on the shift pedal210. Also, a latch projection227can be formed on the support plate221to be inserted between the pair of rods231A,231B. With such construction, when the shift pedal210is turned (moved) by manipulation of a foot, one231A of the rods can be elastically deformed by the push portion212D and the other231B of the rods is elastically deformed by the latch projection227. In the case where manipulation by a foot is released, the shift pedal210can be returned to a predetermined reference position (neutral position) shown in the figure by the existence of the push portion212D and the latch projection227and an elastic force of the pine-needle shaped spring231.

With the detection mechanism (operation unit)200constructed in a manner described above, the support plate221can be turned about the screw member208by loosening the mount bolt229, so that positional regulation of the shift pedal switches222,223relative to the shift pedal210can be readily performed.

Also, the shift pedal detection switches222,223, the shift pedal210, the pine-needle shaped spring231, etc. can be readily exchanged together by removing the support plate221from the base plate202.

Also, the detection switches222,223of this kind can be relatively inexpensive and can contribute to reduction in cost.

In addition, the construction, function and effect except those described above are the same or substantially the same as those in the first embodiment and so an explanation therefor is omitted.

With reference now toFIGS. 11 and 12, an explanation will be given to a third embodiment a speed change controller disclosed comprising a variable mechanism capable of changing a position of that portion (here, a pedal portion of a shift pedal) on an operation part, which is directly manipulated by a foot, relative to a vehicle.

According to this illustrated embodiment, a slot312F is formed at a tip end of a shift pedal310(arm portion312). A pedal portion (pushed portion)314is mounted to the slot312F by a nut315and other implement (for example, a screw), which can be clamped.

Specifically, a male thread portion316can be protrusively provided on the pedal portion (pushed portion)314, the male thread portion316being inserted into the slot312F to be threaded on the nut315.

As a result of such construction, the male thread portion316can be moved in the slot312F by loosening the nut315. Therefore, a rider can regulate the pedal portion (pushed portion)314in a favorite position.

In addition, the construction, function and effect except those described above are the same or substantially the same as those in the first or second embodiment and so an explanation therefor is omitted.

While according to the respective embodiments the moving part and that portion, which is directly manipulated by a foot, on the operation part are the same (that is, a shift pedal) from the viewpoint of simplicity (a small number of parts) in construction, readiness in assembly/adjustment, etc., a moving part and that portion, which is directly manipulated by a foot, included in an operation unit may be made of separate parts in another embodiment.

Subsequently, a fourth embodiment of a speed change controller disclosed herein will be described with reference toFIGS. 13 to 15. The embodiment is a example of a configuration, in which a moving part, of which movement is detected by a detection unit, and a shift pedal directly manipulated by a foot are arranged in separate regions.

Specifically, in the illustrated embodiment, a shift pedal410and an operation unit400are connected to each other by a link member50.

According to the illustrated embodiment, a sensor unit400is provided as a unit connected to “operation unit” described above that includes the moving part, the detection unit, and a base, which supports the units. In one embodiment, the sensor unit can be generally constructed in the same manner as the operation unit200of the second embodiment described above.

The sensor unit400comprises a support plate402corresponding to “base” detachably mounted to an engine casing14. The support plate402is mounted to the engine casing14by engagement of a mount screw (not shown) and a mount hole corresponding to the screw. Here, the mount hole is formed to be made a little larger than a thread diameter whereby some positional regulation relative to the engine casing14is made possible.

A lever member408comprises a moving part, which can move upon manipulation (that is, based on manipulation of a foot) by a foot, is provided on the support plate402to be able to turn about a shaft409.

As shown inFIG. 13, a pair of shift pedal (detection) switches422,423as “detection unit” are arranged in positions close to both sides of the lever member408. As a result of providing the shift pedal (detection) switches422,423in such positions, a shift pedal410described later is turned (moved) in either sense in a vertical direction, and the lever member408is linked with such movement to abut against either of the shift pedal switches422,423, so that contact portions of the switches422,423are pressed and pushed in whereby a switch ON state comes out. In addition, the construction of the shift pedal (detection) switches422,423is the same as that in the second embodiment and so an explanation of a detailed construction is omitted.

As shown inFIG. 15, the lever member408can be formed with a push portion408D, which can be inserted between a pair of rods431A,431B of a pine-needle shaped spring431. Also, a latch projection427can be formed on the support plate402to be inserted between the pair of rods431A,431B. With such construction, when the shift pedal410is turned (moved) by manipulation of a foot, one431A of the rods is linked with such motion to be elastically deformed by the push portion408D and the other431B of the rods is elastically deformed by the latch projection427. In the case where manipulation by a foot is released, the lever member408can be returned to a predetermined reference position shown in the figure by the existence of the push portion408D and the latch projection427and an elastic force of the pine-needle shaped spring431.

Also, as shown inFIG. 13, there cam be provided a rod-shaped link member480, by which the shift pedal410mounted pivotally on a base plate411, and the above-mentioned lever member408(moving part) can be linked with each other. Specifically, an end481A of the link member480can be connected pivotally to the shift pedal410and the other end481B is connected pivotally to the lever member408. Also, the link member480can comprise a cylindrical portion480B and a shaft portion480A insertable into the cylindrical portion480B to be constructed to afford regulation of its total length.

Further, an end23A of the shift shaft23(see e.g.FIG. 2) projects to a position in the vicinity of a tip end of the lever member408from the engine casing14, and an end492A of an arm member492is mounted to the end23A. Also, as shown inFIG. 14, the other end481B of the link member480can be made detachable to the other end492B of an arm member492.

As a result of such construction, when the shift pedal410(specifically, a pedal portion414) is manipulated by a foot in a state, in which the other end481B of the link member480shown inFIG. 13is mounted to the tip end of the lever member408, the lever member408can be turned through the link member480in a predetermined direction. Turning is made downward as shown inFIG. 15(a) or upward as shown inFIG. 15(c) from, for example, a neutral position shown inFIG. 15(b). Therefore, like the embodiment described above, in which the shift pedal itself is a moving part, the lever member408abuts against one422or423of the shift pedal detection switches to bring about an ON state, and its detection signal is transmitted to the engine control unit. An actuator23B is actuated by the engine control unit and the shift shaft23turns to perform shift operation.

On the other hand, as shown inFIGS. 13 and 14, it is possible to remove the other end481B of the link member480from the lever member408to mount the same to the other end492A of the arm member492. Thereby, when the shift pedal410is turned by manipulation of a foot, the arm member492connected to the shift shaft23is turned through the link member480. Turning of the arm member492causes the shift shaft23to be turned in a predetermined direction, so that shift operation is performed mechanically (that is, in the same manner as in a conventional motorcycle).

The link member480can be selectively mounted to the lever member408or the arm member492in this manner whereby it is possible to select the case where an actuator is used to electrically perform speed change (shift) operation and the case where shift operation is performed mechanically without the use of an actuator. Thereby, direct, mechanical speed change operation can be performed by manipulation of a foot in the case where an actuator is in failure.

According to the illustrated embodiment, the case where operation is performed by the sensor unit400and the case where operation is performed mechanically is switched only by changing mounting of the link member480and it is unnecessary to regulate the shift pedal410when such change is made, so that it is possible to readily and rapidly perform the change

In addition, the construction, function and effect except those described above are the same or substantially the same as those in the first or second embodiment and so an explanation therefor is omitted.

Subsequently, a modified example (a fifth embodiment) of the operation unit of the first embodiment will be described with reference toFIGS. 16 and 17.

In addition, only matters featuring the present embodiment are described in detail and the same construction as that in other embodiments is not duplicately described. Those skilled in the art can understand the other components of the present embodiment on the basis of other portions in the specification of the present application and contents of respective drawings referred to in the explanation.

FIGS. 16A and 16Bshow the construction of a detection mechanism (operation unit)500according to the present illustrated embodiment, as viewed from an inner surface side (a side facing a vehicle) of a base plate502at the time of mounting to a vehicle in contrast toFIG. 4. The base plate502corresponding to “base” is a substantially rectangular-shaped plate and mounted to a vehicle body frame (or an engine casing) through mount holes505A to505D in four locations in total by screws (not shown) as shown inFIG. 16A. The mount holes can be formed to be a little larger in diameter than a thread diameter. Thereby, positional adjustment relative to the vehicle body frame (or the engine casing) can be made possible.

Mounted to the base plate502is a shift pedal510, which is an operation part and corresponds to a moving part according to this embodiment. The shift pedal510comprises an arm portion512, of which one end510A (referred below to as “pedal arm base510A”) is mounted pivotally to an inner surface side of the base plate502, and a pedal portion514, which is mounted to a tip end of the arm portion512to be manipulated directly by a foot (a toe tip). Mount holes513A to513C can be provided in three locations in total on the arm portion512to permit mounting of the pedal portion514by screws (or bolt), so that it is possible to regulate a position of the pedal portion according to a rider's body type and preference. InFIG. 16A, the pedal portion514is mounted to the centrally positioned mount hole513B.

The pedal arm base510A is mounted to the base plate502by a screw member508to be able to turn (specifically, being able to swing in two vertical directions) about the screw member508as a rotating shaft. The pedal arm base510A comprises an operating force changing mechanism (capable of functioning as a bodily sensation signal generating mechanism) described later. Also, a detection unit520is mounted coaxial with the pedal arm base510A. That is, as shown inFIG. 16, with the operation unit500according to the embodiment, the detection unit520is provided on the inner surface side of the base plate502to be coaxial with the shift pedal510unlike the first embodiment described above.

The detection unit520comprises a sensor (here, a non-contact type magnetic rotation potentiosensor)522that detects that the shift pedal (moving part)510is moved a predetermined amount or more by manipulation of a foot. The sensor522can comprise a lever portion (probe)524and a drum-shaped magnetic resistance element (not shown). On the other hand, a plurality of pins507can be provided in positions close to the lever portion524.

With such construction, when the shift pedal510is turned (moved) in either sense in a vertical direction according to a rider's shift change operation, the sensor522mounted coaxial with the shift pedal510will turn (move) simultaneously but one of the pins507abuts against the lever portion524to inhibit turning of the lever portion524. As a result, the relative positional relationship of the magnetic resistance element and the lever portion (probe)524changes. Voltage change corresponding to such rotational displacement is generated and a detection signal based on the change is output. The lever portion524comprises an automatic return mechanism composed of a spring (not shown), etc., and is automatically returned to a predetermined position in case of no contact by the pin507.

In addition, a detection signal can be transmitted to the engine control unit (ECU) and a speed change mechanism operates according to the detection signal but a duplicate explanation is omitted since a manner of such operation is the same as that in the first embodiment described above.

The detection unit520described above is provided on the inner surface side of the base plate502whereby an inadvertent contact between a rider's foot and the detection unit520(in particular, a body of the sensor522) is prevented and breakage and failure of the detection unit due to such contact can be beforehand prevented. Also, the shift pedal512and the sensor522are mounted coaxially to the base plate502whereby it is possible to reduce members for mounting in number and processes required for mounting.

Also, a support plate521can be arranged in a position close to the arm portion512of the shift pedal510on the inner surface side of the base plate502. The support plate521can be screwed to the base plate502through mount holes526,529in two locations.

As shown inFIG. 16A, a pine-needle shaped spring531can act as “return mechanism530”, which returns the shift pedal510to a predetermined neutral position, is provided on one529of the mount holes. Formed between a pair of rods (straight ends) of the pine-needle shaped spring531is a latch projection527, which is protrusively provided on a part (push portion)516of the arm portion512of the shift pedal510and the support plate521. With such construction, when the shift pedal510is turned (moved) by manipulation of a foot, one of the rods is elastically deformed by the push portion516and the other of the rods is elastically deformed by the latch projection527. In the case where manipulation by a foot is released, the shift pedal510can be returned to a predetermined position shown in the figure by the existence of the push portion516and the latch projection527and an elastic force of the pine-needle shaped spring531.

Unlike the respective embodiments described above, according to the embodiment, the spring531, which constitutes the return mechanism530, is mounted in a different position from the shift pedal510and a mount shaft of the sensor522. Thereby, it is possible to construct a compact return mechanism without mounting a large diameter spring to the shift pedal510and the mount shaft of the sensor522.

Subsequently, an explanation will be given to an operating force changing mechanism560according to the embodiment. As shown inFIGS. 16A,16B and17, the same plunger561as that described in the first embodiment can be embedded, as a preferred example of the resistance portion provided in the operating force changing mechanism560according to the embodiment, in the arm base510A of the shift pedal510. As shown in the figure, a coil spring562, which is a spring portion of the resistance portion according to the embodiment, can be inserted into a cylindrical-shaped body of the plunger561, and a moving ball564being a surface portion connected to the spring562is mounted to a tip end of the plunger561. The moving ball564is supported by the spring562such that when the moving ball564is pushed axially of the cylindrical-shaped body with a predetermined force or more, the spring562yields to the push force to contract with the result that the moving ball564retreats into the cylindrical-shaped body. On the other hand, when such push disappears, the spring562is elongated by elasticity and the moving ball564returns to an original position at the tip end of the plunger561. According to the embodiment, a tip end portion of the moving ball564is exposed outside in a normal state (FIG. 17).

On the other hand, a slide wall portion572is formed, as a preferred example of the abutting portion provided in the operating force changing mechanism according to the embodiment, in a position on the support plate521, in which it can contact with the moving ball564of the plunger561.

As shown inFIG. 16B, specifically, the slide wall portion572is formed with a slide surface572A, against which the moving ball564is pushed by an elastic force of the plunger561. In the case where the shift pedal510is turned (moved) vertically by manipulation of a foot from a predetermined neutral position (position shown inFIG. 16A), the moving ball564slides vertically (a direction indicated by an arrow inFIG. 16B) correspondingly.

Here, as shown inFIG. 16B, convex portions574A,574B are formed in positions (corresponding to the shift-down bodily sensation signal generating position and the shift-up bodily sensation signal generating position in the first embodiment), to which the moving ball564is moved immediately before the potentiosensor522detects that the shift pedal510has been turned in a predetermined direction, on the slide surface572A.

That is, in a predetermined neutral position, in which shift operation is not performed, and a position therearound, a predetermined torque (reference torque) is given to the moving ball564to enable sliding on the slide surface572A of the slide wall portion572. The torque (pressure) is transmitted to a rider through a foot (that is, a left foot performing shift change operation), which performs shift pedal operation.

On the other hand, when the shift pedal510moves to the shift-down bodily sensation signal generating position or the shift-up bodily sensation signal generating position, the moving ball564comes into contact with the convex portions574A,574B formed the slide surface. At this time, the reference torque cannot cause the moving ball564to get over the convex portions574A,574B and sliding of the moving ball564is impeded in the position. Also, such matter is transmitted to a rider through a foot. Here, a rider heightens torque being given to the shift pedal510to increase pressure applied to the moving ball564whereby the spring562contracts and the moving ball564can get over the convex portions574A,574B while retreating. When the convex portions574A,574B are gotten over, pressure on the moving ball564rapidly decreases. Such series of phenomena are transmitted, as a change (that is, high torque from the reference torque and then to low torque) in torque received from the shift pedal510, to a rider. That is, the phenomena are transmitted as bodily sensation signal to a rider. Specifically, a rider perceives such change in torque as feeling of click through a foot's, sensation.

According to the embodiment, timing, in which such feeling of click is obtained, and timing, in which a detection signal is output from the sensor522, synchronize with each other. Thereby, a rider can perceive the start of speed change control processing through a foot's sensation by the feeling of click (a change in torque) although the speed change operation is performed by a foot being dull as compared with a hand. Then the embodiment is the same as the other embodiments in that the shift actuator is operated by a signal from the engine control unit and the shift shaft23(FIG. 2) is turned in a predetermined direction.

According to the embodiment, the operating force changing mechanism can be constructed compact by providing the plunger561on the shift pedal.

Also, substantially all detection mechanisms including the operating force changing mechanism are provided on the base plate502whereby it is possible to realize both an improvement in productivity and in maintenance.

While the speed change controller described in the second embodiment is constructed such that the pair of shift pedal (detection) switches222,223are used as a detection unit and that contact portions222A,223A of the shift pedal switches222,223are pressed and pushed in by a part of the shift pedal whereby a switch ON state comes out, use of such switches is not limitative.

For example, according to a sixth embodiment, like a detection mechanism (operation unit)600, as a sixth embodiment, shown inFIG. 18, load switches622,623, which detect a load on an operation portion, may contact with both upper and lower surfaces of a shift pedal608. In this case, a detection signal related to shift operation (speed change processing) is output when pedal manipulation by a foot applies a predetermined load on the shift pedal608corresponding to a loaded portion, on which a load is applied. Here, the load switch622reacting when a foot applies a load on the shift pedal608upward is a shift-up detection switch622, and the load switch623reacting when a foot applies a load on the shift pedal608downward is a shift-down detection switch623.

According to the embodiment, since the shift pedal608is arranged in a state of being interposed substantially closely between the pair of load switches622,623, inconvenience such as gutter, etc. is not generated on the shift pedal and a stable assembling can be made. Also, the load switches622,623being a detection unit and the shift pedal608being a loaded portion are provided on a base plate602(here, further a support plate621provided detachably on the base plate602) provided detachably on a vehicle whereby the respective parts can be given stiffness affording application of a large load to such a degree that a rider can grasp feeling of operation although operation is performed by a foot being dull as compared with a hand. Also, it is possible to achieve an improvement in mechanism stiffness and an improvement in productivity and in maintenance.

In addition, other components (for example, (1) the base plate602, (2) the support plate621, (3) a pine-needle shaped spring631, a push portion608D, and a latch projection627, which constitute a return mechanism630(here, functions as a holding mechanism that holds a pedal position), and (4) a screw member609that mounts the shift pedal608to the support plate621) shown inFIG. 18are the same in construction as those in the second embodiment.

Various embodiments other than the embodiments described above can be adopted in embodying the invention.

For example, while a lever-shaped shift pedal manipulated by a tip of a toe of a foot having a shape common to sport type motorcycles is used as an operation part or a moving part, it is not limitative but other shape will do provided that a shift pedal is manipulated by a foot. For example, a shift pedal may be in the form of a wide plate, on which a foot is put, as used in American type motorcycles.

Also, while a base (base plate), which constitutes an operation unit, is mounted to the vehicle body frame10(or the engine casing14) in the respective embodiments, this is not limitative but it may be mounted to an appropriate portion (for example, a power source such as engine, motor, etc., other constituents of a vehicle such as transmission, etc., or accessory members such as under-cowling, engine guard, etc.) according to shape and kind of a vehicle.

Also, a spring used in a return mechanism is not limited to the pine-needle shaped spring described above but may assume any configuration as far as a desired return mechanism can be constituted. For example, a bent leaf spring will do.

Also, while the third embodiment described above teaches an arrangement, which is composed of a slot and a screw, as a preferred example of a variable mechanism capable of changing a position of that portion (specifically, a pedal portion of a shift pedal) on an operation part, which is directly manipulated by a foot, relative to a vehicle, this is not limitative. For example, a mechanism will do, in which an arm portion of a shift pedal is composed of a two-piece or three-piece or more rod, which is adjustable in length, and a length of the rod (arm portion) is regulated according to a rider's body type and favorite.

Also, while according to the respective embodiments described above the shift pedal (the moving part of the operation part) are moved (turned) in two vertical directions in the same manner as in conventional motorcycles, a direction, in which the moving part on the operation part or the part directly manipulated by a foot in the speed change controller of the invention is moved, is not limited to two vertical directions. Such direction may be a longitudinal direction or a left and right direction (for example, a direction approaching a vehicle body or a direction away from a vehicle body) of a driver's foot with a ride posture as a reference.

Also, the devices described above, which realizes an operating force changing mechanism, is not limited to the plunger constructed in the manner described above. For example, one of the resistance portion and the abutting portion is made of a magnet and the other is made of a magnetic material (iron, or the like) whereby torque can be changed by a magnetic force when the detection unit detects shift operation.

Also, while the resistance portion (plunger) described above comprises a coil spring as a spring portion in a body thereof, this configuration is not limitative. For example, the resistance portion may comprise a piston member, a part of which is exposed to a surface thereof by making use of elasticity of volume of gases and filling gases such as air or the like therein.

Also, a speed change mechanism, which constitutes the speed change controller of the invention, is not limited to a constantly meshing type multistage speed change mechanism but may be one, which can operate on the basis of speed change operation detected by a detection mechanism. For example, a V-belt type continuously variable transmission controlled by a motor is suited to a speed change mechanism, which constitutes the speed change controller of the invention.

As described above, in one embodiment, a speed change controller for saddle-type vehicle includes an operation unit that comprises an operation part, which is manipulated by a foot, and a detection part, which detects manipulation by a foot and is detachably and mounted as a unit to the vehicle.

An advantage of this embodiment, is that because an operation unit provided integrally with an operation part, which is manipulated by a foot, and a detection part, which detects manipulation by a foot, is detachably and integrally mounted to a vehicle, shift operation can be readily performed in the same feeling of operation as conventional one because manipulation by a foot is detected and an actuator is operated in an arrangement, in which a shift actuator is used to perform speed change operation.

Also, since it is not necessary to connect an operation part, which is manipulated by a foot, to a shift shaft through a linkage unlike a conventional arrangement and the operation part and the detection part constitute an integral operation unit, it is possible to readily perform mounting to a vehicle at the time of production.

Further, since the operation part and the detection part are made integral or formed as a unit, it is possible to adjust the detection part even before the operation unit, etc. are mounted to a vehicle. Incidentally, in the case where the operation part and the detection part are separately mounted to a vehicle, it is necessary to manipulate the operation part after being mounted to a vehicle to regulate the detection part.

Furthermore, since the operation part and the detection part are made integral, certain detection can be made irrespective of a position of the operation part, so that positional regulation of the operation part can be readily performed according to a user's favorite only by changing a position of the operation unit.

In another embodiment, a speed change controller for saddle-type vehicles includes a base, a moving part supported on the base and moved by manipulation by a foot, a detection part, which detects manipulation by a foot, and a return mechanism, which returns the moving part to a predetermined position. These components can be coupled together as a unit to form an operation unit. The operation unit can be detachably and mounted to a vehicle body or an engine as a unit.

An advantage to this embodiment is that since a base, a moving part supported on the base and moved by manipulation by a foot, a detection part, which detects manipulation by a foot, and a return mechanism, which returns the moving part to a predetermined position, is provided integrally to form an operation unit, and the operation unit is detachably and integrally mounted to a vehicle body or an engine, it is possible to readily perform mounting to a vehicle at the time of production described above and it is possible to adjust the detection part even before the operation unit, etc. are mounted to a vehicle. Besides, since the moving part and the detection part are made integral, certain detection can be made irrespective of a position of the operation unit, so that positional regulation of the moving part can be readily performed according to a user's favorite only by changing a position of the operation unit. Also, since a return mechanism, which returns the moving part to a predetermined position (neutral position), is provided integrally on the operation unit, and detachably and integrally mounted to a vehicle, the workability of arrangement is favorable and even in the case where the moving part is not connected to the shift shaft through a linkage like a conventional arrangement, it can be readily returned to the neutral position.

In another embodiment, a speed change controller for saddle-type vehicle, in which a moving part moved by manipulation by a foot, a detection part, which detects manipulation by a foot, and a return mechanism, which returns the moving part to a predetermined position, are detachably provided on a vehicle body or an engine.

According to this embodiment since the moving part moved by manipulation by a foot, the detection part, which detects manipulation by a foot, and the return mechanism, which returns the moving part to a predetermined position, are detachably provided on a vehicle body or an engine so that respective parts are mounted with a vehicle body or an engine as a reference, it is possible to decrease a mount error and even in the case where the moving part is not connected to the shift shaft through a linkage like a conventional arrangement, it can be readily returned to the neutral position since the return mechanism, which returns the moving part to a predetermined position (neutral position), is provided.

In yet another embodiment, a speed change controller for saddle-type vehicles includes a sensor unit comprising a lever member mounted pivotally to a support plate and a detection part, which is made ON by turning of the lever member. The unit is arranged on a vehicle body or an engine. A link member for connection of the lever member and a shift pedal is provided, and an end of the link member can be removed from the lever member and attached to an arm member provided on a shift shaft.

According to this embodiment, since a sensor unit including a lever member mounted pivotally to a support plate and a detection part, which is made ON by turning of the lever member, is arranged on a vehicle body or an engine, a link member for connection of the lever member and a shift pedal is provided, and an end of the link member can be removed from the lever member and attached to an arm member provided on a shift shaft, the link member can be used to afford selectively mounting to the lever member or the arm member whereby it is possible to select the case where an actuator is used to electrically perform shift operation and the case where shift operation is performed mechanically without the use of an actuator. Thereby, mechanical speed change operation can be performed by manipulation of a foot when an actuator is in failure. Besides, the case where operation is performed by the sensor unit and the case where operation is performed mechanically is switched only by changing mounting of the link member and it is unnecessary to regulate the operation part when such change is made, so that it is possible to readily and rapidly perform the change.

According to the embodiments described herein, it is possible to provide a saddle-ride type vehicle provided with a speed change controller, in which manipulation by a rider's foot is improved.

Although the present invention has been described in terms of a certain embodiment, other embodiments apparent to those of ordinary skill in the art also are within the scope of this invention. Thus, various changes and modifications may be made without departing from the spirit and scope of the invention. For instance, various components may be repositioned as desired. Moreover, not all of the features, aspects and advantages are necessarily required to practice the present invention. Accordingly, the scope of the present invention is intended to be defined only by the claims that follow.
