For example, the load of the operator and/or passenger is generally carried by the rear wheel 112. Further, any cargo positioned within saddlebags 176, 178 and/or removable trunk 174 (shown in phantom in FIG. 1) is generally carried by the rear wheel 112. By moving more of the load forward, vehicle 100 has increased cargo carrying capability and better stability when an operator holds vehicle 100 upright while stopped.
Referring to FIG. 1, additional steps have been taken with regard to vehicle 100 to lower center of gravity 298 of two-wheeled vehicle 100 and to move center of gravity 298 towards front wheel 110. As one example, of shifting center of gravity 298 forward and lower, a battery of vehicle 100 whose location 300 is shown in phantom in FIG. 1 is located in front of engine 124 behind front wheel 110. The battery is used to provide power for the electrical start of vehicle 100 to start vehicle 100 and/or power various accessories or lights of vehicle 100 while engine 124 is not running.
Location 300 of the battery also provides for easy access to the battery. Battery cables may be attached to the battery without removing any of the body panels of vehicle 100 or removing seat 102 of vehicle 100. As such, the battery may be charged or jumped without the removal of seat 102 or any of the body panels.
In one embodiment, center of gravity 298 is about 487 mm (about 19.17 inches) above ground 114 and about 3% forward of a midpoint of a line connecting front axle 264 of front wheel 110 and a rear axle 265 (see FIG. 5) of rear wheel 112 when vehicle 100 is full of fluids without taking into account the weight of the trunk 174, the weight of any cargo, or the weight of the operator or passenger. Thus, the load between front wheel 110 and rear wheel 112 is generally balanced.
Referring to FIG. 12, the fuel storage system 270 of vehicle 100 is shifted forward compared to traditional motorcycles which further assists in balancing the load between front wheel 110 and rear wheel 112. As shown in FIG. 12, right fuel storage tank 272 is positioned on a right side of front frame member 182 and outward of front frame member 182 and left fuel storage tank 274 is positioned on a left side of front frame member 182 and outward of front frame member 182. Right fuel storage tank 272 and left fuel storage tank 274 are supported by front frame member 182 and are positioned around the air channel 192 within front frame member 182. In one embodiment, right side fuel storage tank 272 and left side fuel storage tank 274 are positioned to balance the fuel load of vehicle 100 about centerline plane 116. Steering assembly 130 is positioned between right side fuel storage tank 272 and left side fuel storage tank 274. In one embodiment, at least a portion of one or both of right fuel storage tank and left fuel storage tank overlaps at least one of a top portion of front frame member 182 and a bottom portion of front frame member 182.
Referring to FIGS. 10 and 11, right side fuel storage tank 272 and left side fuel storage tank 274 are in fluid communication with each other through an upper fluid conduit 310 and a lower fluid conduit 312. Fuel is provided from fuel storage system 270 through a fuel line 314 to engine 124. Fuel line 314 is connected to a fuel pump 316 located in right side fuel storage tank 272. Fuel pump 316 pumps fuel from the interior of right side fuel storage tank 272 through fuel line 314 to engine 124. In one embodiment, fuel pump 316 has an integrated roll-over valve built into it as a safety precaution. Also connected to fuel pump 316 is a vent line 324 which is coupled to canister (not shown) filled with filter-activated charcoal.
As shown in FIG. 2, vehicle 100 includes a side stand 320. Vehicle 100, like many motorcycles, is supported by front wheel 110, rear wheel 112, and side stand 320 when an operator is not positioned on vehicle 100. One of example of when this is likely the case is when an operator is introducing fuel into fuel storage system 270. To introduce fuel into fuel storage system 270, a gas cap 322 is removed from right side fuel storage tank 272. Gas is then introduced into right side fuel storage tank 272. In one embodiment, storage tank 272 includes a filler neck (not shown) that extends down into tank 272 from gas cap 322 which controls the amount of fuel that may be put in tank 272 and tank 274. Fuel in right side fuel storage tank 272 travels through line 312 into left side fuel storage tank 274 due to the leaning of vehicle 100 to the left side because vehicle 100 is supported on side stand 320. Line 310 connects the airspace above the fuel in left side fuel storage tank 274 and right side fuel storage tank 272. As fuel travels from right side fuel storage tank 272 into left side fuel storage tank 274 air is displaced through line 310 from left side fuel storage tank 274 into right side fuel storage tank 272.
In one embodiment, gas cap 322 includes a vapor and pressure release valve. The vapor and pressure release valve prevents the presence of unwanted pressure fluctuations being present in fuel storage tanks 272, 274. For example, if line 324 gets pinched and the fuel pump 316 continues to pump fuel out of tank 272, tank 272 may implode unless air is permitted to enter tank 272 through the vapor and pressure release valve of gas cap 322.
Returning to FIG. 5, a swing arm 380 is rotatably coupled to rear frame member 184 through a pivot shaft 382. Swing arm 380 may rotate downward in direction 384 away from rear frame member 184 and upward in direction 386 toward rear frame member 184. Swing arm 380 includes a left arm 390, a right arm 392 and a middle portion 394. Rear wheel 112 is received in the area 396 between left arm 390 and right arm 392 and rearward of middle portion 394. In one embodiment, swing arm 380 is a one-piece casting. In one example, swing arm 380 is cast through a lost core process.
As explained herein, a rear suspension 400 is coupled to swing arm 380 through middle portion 394. Referring to FIGS. 13-15, rear suspension 400 is shown.
Referring to FIG. 13, rear frame member 184 and swing arm 380 are shown assembled. Further, rear wheel 112 is shown assembled to swing arm 380. In one embodiment, rear axle 265 is coupled to swing arm 380 with a clip. Additional details regarding the coupling of an axle to a chassis are found in U.S. patent application Ser. No. 11/085,754, filed Mar. 21, 2005, published as U.S. Published Patent Application No. US2006-0226631A1, the disclosure of which is expressly incorporated by reference herein.
Further, a support bracket 402 is shown attached to rear frame member 184. Support bracket 402 supports saddlebags 176 and 178 and other components of the rear body of two-wheeled vehicle 100. Saddlebag 176 is supported by a left portion 404 of support bracket 402 and saddlebag 178 is supported by a right portion 406 of support bracket 402.
Support bracket 402 also serves as a heat sink for the electronic control module (“ECM”) 405 of vehicle 100 which is supported by a middle portion 408 of support bracket 402. ECM 405 is bolted or otherwise coupled to support bracket 402 which is bolted or otherwise coupled to rear frame member 184. In one embodiment, support bracket 402 is made of aluminum and rear frame member 184 is also made of aluminum. The aluminum of support bracket 402 and rear frame member 184 dissipates the heat produced by the electrical components, such as a processor, of ECM 405.
As shown in the FIG. 13, rear frame member 184 and swing arm 380 are rotatably coupled through a first connection, pivot shaft 382. A second connection is made between rear frame member 184 and swing arm 380 through rear suspension 400. In one embodiment, swing arm 380 and rear suspension are coupled to the frame in less than three locations. In one embodiment, swing arm 380 and rear suspension are coupled to the frame in two locations.
Referring to FIG. 15, rear suspension 400 includes a shock absorber 410, a pushrod 412, and a connecting link 414. The linkage of pushrod 412 and connecting link 414 scale the movement of the shock absorber 410 by a multiplication factor to correlate to the movement of swing arm 380.
As shown in FIG. 15, connecting link 414 is rotatably connected to rear frame member 184 through a pivot pin 416 and associated bearing and rotatable about a horizontal axis 420 in directions 422, 424. Pushrod 412 is rotatably coupled to swing arm 380 through a coupler 426 received in a rubber bushing and is rotatably coupled to connecting link 414 through a coupler 428. In one embodiment, coupler 428 is a spherical bearing along with a bolt and nut. Shock absorber 410 is rotatably coupled to swing arm 380 through a coupler 430 received in a rubber bushing and is rotatably coupled to connecting link 414 through a coupler 432. In one embodiment, coupler 432 is a spherical bearing along with a bolt and nut. Shock absorber 410 has shown in FIG. 15 is coupled to swing arm 380 and rear frame member 184 in a generally vertical orientation. In one embodiment, shock absorber 410 is an air shock available from KYB America LLC located at 140 N. Mitchell Court, Addison, Ill. 60101.
In one embodiment, shock absorber 410 is an air adjustable shock. Referring to FIG. 14, shock absorber 410 has a suspension adjuster coupled thereto, illustratively air line 454. The amount of air in shock absorber 410 may be adjusted upward or downward by adding air to shock absorber 410 or removing air from shock absorber 410, respectively. In one embodiment, an air inlet valve 456 is accessible from within rear bodywork 160. An operator may couple air inlet valve 456 to a standard air compressor to adjust the amount of air in shock absorber 410. By being capable to adjust the amount of air in air shock 410, an operator may adjust the ride height of vehicle 100 for the amount of cargo weight being carried.
Referring to FIG. 13A, air inlet valve 456 extends through an opening 181 in a saddlebag base member 175 and is secured to saddlebag base member 175 with a retainer 183, illustratively a nut. Saddlebag base member is coupled to support bracket 402 and rear frame member 184. The location of opening 181 is covered by saddlebag cover 179, when saddlebag cover 179 is in a closed position, such as shown in FIG. 1. As such, an operator would open saddlebag cover 179 to access air inlet valve 456 which extends through opening 181. By having opening 181 in a spaced apart location from storage compartment 177, an operator does not need to disturb and/or remove any cargo to access air inlet line 456.
As shown in FIG. 16A, rear suspension 400 is arranged such that pushrod 412 and connecting link 414 move in a plane which is not parallel to the centerline plane 116 of vehicle 100. In the illustrated embodiment, pushrod 412 and connecting link 414 move in a plane which is perpendicular to the centerline plane 116 of the vehicle 100. In one embodiment, pushrod 412 and connecting link 414 move in multiple planes, each of which is not parallel to the centerline plane.
Referring to FIGS. 16-19, the operation of rear suspension 400 is described. As described herein, rear suspension 400 exhibits a generally constant motion ratio through the travel range of rear suspension 400. In one embodiment, rear suspension 400 is arranged so that pushrod 412 and connecting link 414 move in a plane which is not parallel to the centerline plane 116 of vehicle 100, but the motion ratio of rear suspension 400 is one of either a linear rising rate through the travel range of rear suspension 400 or a generally linear falling rate through the travel range of rear suspension 400. In one embodiment, rear suspension 400 is arranged so that pushrod 412 and connecting link 414 move in a plane which is parallel to the centerline plane 116 of vehicle 100 and the motion ratio of rear suspension 400 is generally constant through the travel range of rear suspension 400.
FIG. 16A illustrates a side view of rear frame member 184, swing arm 380, rear wheel 112, and rear suspension 400 when rear suspension 400 is in an extended state. FIG. 16B illustrates rear suspension 400 when in the extended state of FIG. 16A. FIG. 17A illustrates a side view of rear frame member 184, swing arm 380, rear wheel 112, and rear suspension 400 when rear suspension 400 is in a mid-travel state. FIG. 17B illustrates rear suspension 400 when in the mid-travel state of FIG. 17A. FIG. 18A illustrates a side view of rear frame member 184, swing arm 380, rear wheel 112, and rear suspension 400 when rear suspension 400 is in a compressed state. FIG. 18B illustrates rear suspension 400 when in the compressed state of FIG. 18A. In one embodiment, rear suspension 400 has about 5 inches (about 12.7 centimeters) of rear suspension travel and a seat height (d1 in FIG. 21) of up to about 26.5 inches (about 67.31 centimeters).
In the extended state shown in FIG. 16B, a length (L) of shock absorber 410 is extended. The upper coupler 432 connecting shock absorber 410 and connecting link 414 is generally higher than the upper coupler 428 connecting pushrod 412 and connecting link 414. Connecting link 414 is rotated from horizontal in direction 422. The extended state corresponds to a state wherein vehicle 100 is not supporting an operator, passenger, or cargo.
In the mid-travel state shown in FIG. 17B, due to the upward movement of swing arm 380 shock absorber 410 is compressed thereby reducing a length (L) of shock absorber 410 compared to the extended state. In one embodiment, a lower portion of shock absorber 410 moves upward with swing arm 380 and an upper portion of shock absorber 410 moves downward due to the rotation of connecting link 414. This may be due to the addition of an operator or cargo. The upper coupler 432 connecting shock absorber 410 and connecting link 414 is lower compared to the extended state and the upper coupler 428 connecting pushrod 412 and connecting link 414 is higher compared to the extended state. Connecting link 414 is rotated in direction 424 relative to the extended state.
In the compressed state shown in FIG. 18B, a length (L) of shock absorber 410 is reduced compared to the mid-travel state. This may be due to the addition of both an operator and cargo and/or the further addition of a passenger. The upper coupler 432 connecting shock absorber 410 and connecting link 414 is lower compared to the mid-travel state and the upper coupler 428 connecting pushrod 412 and connecting link 414 is higher compared to the mid-travel state. Connecting link 414 is rotated in direction 424 relative to the mid-travel state.
As mentioned herein, rear suspension 400 has a generally constant overall motion ratio (MR) through the suspension travel. Motion ratio is the rear axle 265 displacement divided by the shock absorber 410 displacement. Referring to FIG. 19, as represented by line 450 when considering only the movement from a side view (FIGS. 16A, 17A, 18A) which is in-plane with the centerline plane 116 of vehicle 100 the motion ratio of rear suspension 400 is progressive or increasing with the extent of the travel. The motion ratio when considering only the in-plane movement may be calculated as the ratio of the length of the lever arm causing the linkage of rear suspension 400 to move (the horizontal distance from the pivot of the swing arm 380 with rear frame member 184 to rear axle 265) and the length of the lever arm that the linkage works through (the perpendicular distance from the pivot of the swing arm 380 with rear frame member 184 to the pivot of the shock absorber and the swingarm). In one embodiment, the motion ratio from the side view increases about 10.3% as the swingarm moves upward.
In contrast, the movement of the linkage, pushrod 412 and connecting link 414, is arranged in one embodiment to achieve a regressive motion ratio of about 26%. When combined with the progressive nature of the shock absorber 410 and the progressive in-plane motion ratio, a generally constant motion ratio is achieved. The geometry of the connecting link 414 and the placement of the pivot points (couplers 428, 432) dictate the motion ratio of the linkage. In one embodiment, the pivot locations of couplers 428, 430 are designed to give an overall generally constant motion ratio which is less than about 1.5. In the illustrated embodiment, the pivot locations of couplers 428, 430 are designed to give an overall linkage motion ratio of approximately 0.5, and to ensure that this motion ratio is constant through the suspension travel range. The overall motion ratio of rear suspension 400 is represented by line 452 in FIG. 19.
The calculation of the overall motion ratio may be carried out as follows. The motion ratio (MR) may be found from equation 1




  
    
      
        MR
        =

This assists in providing a more constant gap around rear lighting assembly 1000. Rear lighting assembly 1000 is generally flush with bodywork 160.
Vehicle 100 includes a windshield 148 which directs air flow away from an operator. Referring to FIG. 47A, in prior art vehicles a flow of air strikes a front surface of a windshield and travels up the windshield due to the tilt of the windshield and the movement of the vehicle. The air flow will once clearing the top portion of the windshield travel on and strike the operator, such as in the face. This may adversely effect the operator.
Referring to FIG. 47B, windshield 148 includes a front windshield member 1100 and a back windshield member 1102. In one embodiment, front windshield member 1100 is made from a generally transparent material, such as glass or plastic. A flow of air 1104 encounters windshield 148 and a first portion 1110 of the air 1104 travels up generally along a front surface 1106 of front windshield member 1100. A second portion 1112 of the air 1104 passes between front windshield member 1100 and rear windshield member 1102 and travels generally up along a back surface 1108 of front windshield member 1100. Once at a top portion 1114 of front windshield member 1100, the first portion 1110 of air 1104 interacts with the second portion 1112 of air 1104. The upward movement of second portion 1112 forces the recombined air flow 1116 to remain generally moving with an upward slope until air flow 1116 clears the operator.
Referring to FIG. 49, front windshield member 1100 is mounted to a support bracket 1120. Support bracket 1120 is rotatably coupled to a mount 1122 which is coupled to a sled 1124 of a linear actuator 1126. Linear actuator 1126 includes a motor which rotates a threaded rod which engages sled 1124 to move sled 1124 in directions 1128 and 130. Linear actuator 1126 is supported by mounting bracket 206 and is held stationary except for sled 1124. In one embodiment, linear actuator 1126 is available from Asahi Denso located at 1126 Nakajo, Hamamatsu City, Shizuoka, 438-0043 Japan.
Support bracket 1120 is also rotatably coupled to a pair of links 1129 and 1131 which are coupled to a support rod 1132. Links 1129 and 1131 are rotatably coupled to support bracket 1120 through couplers 1133 and 1135 which are received by apertures 1134 and 1136 of support bracket 1120. Support rod 1132 rotates relative to mounting bracket 206 in directions 1140 and 1142. Bias members 1144 and 1146, illustratively springs, interact with mounting bracket 206 and links 1129 and 1131, respectively, to bias support rod 1132 in direction 1140.
Second windshield member 1102 is coupled to mounting bracket 206. Links 1129 and 1131 extend through openings 1148 and 1150 of second windshield member 1102, respectively, as shown in FIG. 50.
Second windshield member 1102 remains stationary relative to mounting bracket 206. First windshield member 1100 is movable relative to second windshield member 1102 generally in directions 1128 and 1130 between a raised position 1152 (shown in phantom in FIG. 48) and a lowered position 1154 (see FIG. 48). As shown in FIG. 48, first windshield member 1100 is tilted at a first angle from vertical in the lowered position 1154 and a second angle from vertical in the raised position 1152, the second angle being less than the first angle. Further, a position of a top edge of the first windshield member 1100 being vertically aligned when the first windshield member 1100 is in the raised position and the when the first windshield member 1100 is in the lowered position.
Illustratively, from lowered position 1154 an input is received by linear actuator 1126 from an input actuated by the operator. In one embodiment, the input is a toggle switch provided on the handlebars. The motor of linear actuator 1126 moves sled 1124 in direction 1130. This causes support bracket 1122 to also move in direction 1130 resulting in links 1129 and 1131 to rotate in direction 1142. As support bracket 1122 is moved in direction 1130, first windshield member 1100 is also moved in direction 1130.
Referring to FIG. 48, in one embodiment, first windshield member 1100 and second windshield member 1102 are parallel to each other in the lowered position 1154 and spaced apart to provide airflow between first windshield member 1100 and second windshield member 1102. In one embodiment, first windshield member 1100 and second windshield member 1102 are titled relative to front face 204 of mounting bracket 206 at an angle of 45 degrees in the lowered position 1154. In the raised position 1152, first windshield member 1100 and second windshield member 1102 are further spaced apart to permit a higher amount of airflow between first windshield member 1100 and second windshield member 1102. First windshield member also tips upward due to rotation of links 1129 and 1131. This results in windshield member 1100 when in the raised position 1152 not being parallel with windshield member 1102 as it is in the lowered position 1154.
In one embodiment, the amount of airflow in the raised position 1152 is sufficient to cause airflow 1116 to be directed as shown in FIG. 47B. This assists in protecting the operator from the weather. The amount of airflow in the lowered position 1154 is not sufficient to cause airflow 1116 to be directed as shown in FIG. 47B. Rather, airflow 1116 is directed towards the operator and provides cooling to the operator.
Referring to FIG. 51, in one embodiment, a scissor linkage 1158 is implemented to connect windshield member 1100 to linear actuator 1126. As shown in FIG. 51, three pairs of links 1160A-B, 1162A-B, and 1164A-B form two diamond shapes. Links 1160A-B are rotatably coupled together at a first pivot 1166. Links 1160A-B are rotatably coupled to links 1162A-B, respectively, at pivots 1168A-B. Links 1162A-B are rotatably coupled together at pivot 1170. Links 1162A-B are rotatably coupled to links 1164A-B, respectively, at pivots 1172A-B. Links 1164A-B are rotatably coupled together at pivot 1174.
As shown in FIG. 51, pivot 1166 is held stationary. Pivot 1170 is coupled to linear actuator 1126 and moves in directions 1128 and 1130. Pivot 1174 is coupled to windshield member 1100 and moves in directions 1128 and 1130 in response to the movement of pivot 1170. Scissor linkage 1158 provides a multiplication factor to the movement of pivot 1170. Based on the length of links 1160A-B, 1162A-B, and 1164A-B, the displacement of pivot 1174 in direction 1130 may be greater than the displacement of pivot 1170 in direction 1130. This permits windshield member 1100 to have a greater range of travel. In one embodiment, the ratio of the movement of pivot 1170 to the movement of pivot 1174 is greater than 1:2. In one embodiment, the ration of the movement of pivot 1170 to the movement of pivot 1174 is greater than 1:3. In one embodiment, the ratio of the movement of pivot 1170 to the movement of pivot 1174 is about 1:3.4125. In one embodiment, windshield 1100 has about 203 mm of travel.
