This invention generally relates to electromechanical apparatus for use with coupling assemblies to obtain controllable or selectable one-way clutch assemblies which include such apparatus.
Coupling assemblies such as clutches are used in a wide variety of applications to selectively couple power from a first rotatable driving member, such as a driving disk or plate, to a second, independently rotatable driven member, such as a driven disk or plate. In one known variety of clutches, commonly referred to as “one-way” or “overrunning” clutches, the clutch engages to mechanically couple the driving member to the driven member only when the driving member rotates in a first direction relative to the driven member. Once so engaged, the clutch will release or decouple the driven member from the driving member only when the driving member rotates in a second, opposite direction relative to the driven member. Further, the clutch otherwise permits the driving member to freely rotate in the second direction relative to the driven member. Such “freewheeling” of the driving member in the second direction relative to the driven member is also known as the “overrunning” condition.
U.S. Pat. No. 5,927,455 discloses a bi-directional overrunning pawl-type clutch, U.S. Pat. No. 6,244,965 discloses a planar overrunning coupling, and U.S. Pat. No. 6,290,044 discloses a selectable one-way clutch assembly for use in an automatic transmission.
U.S. Pat. Nos. 7,258,214 and 7,344,010 disclose overrunning coupling assemblies, and U.S. Pat. No. 7,484,605 discloses an overrunning radial coupling assembly or clutch.

Metal injection molding (MIM) is a metalworking process where finely-powdered metal is mixed with a measured amount of binder material to comprise a ‘feedstock’ capable of being handled by plastic processing equipment through a process known as injection mold forming. The molding process allows complex parts to be shaped in a single operation and in high volume. End products are commonly component items used in various industries and applications. The nature of MIM feedstock flow is defined by a physics called rheology. Current equipment capability requires processing to stay limited to products that can be molded using typical volumes of 100 grams or less per “shot” into the mold. Rheology does allow this “shot” to be distributed into multiple cavities, thus becoming cost-effective for small, intricate, high-volume products which would otherwise be quite expensive to produce by alternate or classic methods. The variety of metals capable of implementation within MIM feedstock are referred to as powder metallurgy, and these contain the same alloying constituents found in industry standards for common and exotic metal applications. Subsequent conditioning operations are performed on the molded shape, where the binder material is removed and the metal particles are coalesced into the desired state for the metal alloy.

Referring now to FIGS. 1-5, there is illustrated a planar, controllable coupling assembly, generally indicated at 11. The assembly 11 includes a first coupling member, generally indicated at 10, a notch plate or member, generally indicated at 12, and an electromechanical apparatus, generally indicated at 15. The coupling assembly 11 may be a ratcheting, one-way clutch assembly.

At least one of the members 10 and 12 is mounted for rotation about a common rotational axis 20.
The outer coupling face 14 of the housing part 13 has a single, T-shaped recess or pocket 22, as best shown in FIGS. 5 and 6. The recess 22 defines a load-bearing first shoulder 24. The second coupling face 16 of the notch plate 12 has a plurality of recesses or notches (not shown but well known in the art). Each notch of the notches defines a load-bearing second shoulder.
Referring to FIGS. 2, 4, 5, 6, 8 and 9, the electromechanical apparatus 15 may include a locking strut or element, generally included at 26, disposed between the coupling faces 14 and 16 of the housing part 13 and the member 12, respectively, when the members 10 and 12 are assembled and held together.
The element 26 may comprise a metal locking element or strut movable between first and second positions. The first position (FIGS. 4 and 9) is characterized by abutting engagement of the locking element 26 with a load-bearing shoulder (not shown) of the member 12 and the shoulder 24 of the pocket 22 formed in an end wall 28 of the housing part 13. The second position (FIGS. 2, 5, 6 and 8) is characterized by non-abutting engagement of the locking element 26 with a load-bearing shoulder of at least one of the member 12 and the end wall 28.
Alternatively, the apparatus 15 may include an impact energy storage element or synthetic rubber strut, generally indicated at 30 in FIGS. 10 and 11, to dampen the rotation between the members 10 and 12.
As previously mentioned and referring to FIGS. 5-9, the electromechanical apparatus 15 includes the housing part 13 which has a closed axial end including the end wall 28. The end wall 28 has the outer coupling face 14 with the single pocket 22 which defines the load-bearing shoulder 28 which is in communication with an inner face 29 of the end wall 28. The housing part 13 may be a powdered metal or aluminum (MIM) part.
Referring to FIGS. 5, 8 and 9, the apparatus 15 also includes an electromagnetic source, generally indicated at 31, including at least one excitation coil 33 which is at least partially surrounded by the housing part 15.
The element or strut 26 is shown in FIGS. 2, 5, 6 and 8 as being received within the pocket 22 in a refracted, uncoupling position. The strut 26 is movable outwardly from the pocket 22 to an extended, coupling position (FIGS. 4 and 9) characterized by abutting engagement of the strut 26 with a load-bearing shoulder of the notch plate 12.
The apparatus 15 also includes a reciprocating armature, generally indicated at 35, arranged concentrically relative to the at least one excitation coil 33 and is axially movable when the at least one excitation coil 33 is supplied with current. The armature 35 is connected at its leading end 37 to the element 26 to move the element 26 between its coupling and uncoupling positions.
When the element of the apparatus 15 is the rigid locking element 26, the element 26 controls the operating mode of the coupling assembly 11. When the element of the apparatus 15 is the impact energy storage element 30 of FIGS. 10 and 11, the element 30 absorbs and stores impact energy to reduce undesirable noise and contact stress caused by a transition between operating modes of the coupling assembly 11.
Whether the element or strut is a locking element or an energy storage element, the element 26 or 30 is pivotally connected to the leading end 37 of the armature 35 wherein the armature 35 pivotally moves the element 26 or 30 within the pocket 22 in response to reciprocating movement of the armature 35.
The apparatus 15 also preferably includes a return spring 41, a reaction plate 43 and a hollow tube 45 about which the coil 33 is wound and through which the armature moves. The spring 41 and the plate 43, which is secured to the opposite end of the armature 35, returns the armature 35 to its home position when the coil 33 is de-energized, thereby returning the element 26 or 30 to its uncoupling position. In other words, at least one return biasing member in the form of the return spring 41 urges the armature 35 through the plate 43 to a return position which corresponds to the uncoupling position of the element 30 or 26.
The housing may also include a stamped metal cup 39 which preferably has holes to allow oil to circulate within the housing. Preferably, the at least one coil 33, the housing part 13, the cup 39 and the armature 35 comprise a low profile solenoid. The locking element 26 may be a metal injection molded (i.e. MIM) strut.
Referring to FIGS. 10 and 11, the storage element 30 may include a rigid insert 40 and an elastomeric outer covering layer, generally included at 47, bonded to the insert 40. The outer covering layer 47 may be molded over the insert 40 in a thermoset injection molding process.
The storage element 30 carries high temperature-resistant elastomeric material defining opposite end sections 34 and 36 of the storage element 30. One of the end sections 34 is configured to deflect upon abutting engagement with the shoulder 24 and the other end section 36 deflects upon engagement with a shoulder of the notch plate 12.
The housing part 15 has at least one apertured attachment flange 49 and, preferably, two apertured attachment flanges 49 to attach the apparatus 15 to the coupling member 10 of the coupling assembly 11.
Each element, either 30 or 26, includes at least one and, preferably, two projecting leg portions 51 which provide an attachment location for the leading end 37 of the armature 35. Each leg portion 51 has an aperture 53. The apparatus 15 further comprises a pivot pin 55 received within each aperture 53 to allow rotational movement of the element 30 or 26 in response to reciprocating movement of the armature 35 wherein the leading end 37 of the armature 35 is connected to the element 30 or 26 via the pivot pin 55.
Preferably, each aperture 53 is an oblong aperture which receives the pivot pin 55 to allow both rotation and translational movement of the element 30 or 26 in response to reciprocating movement of the armature 35.
Each locking strut 26 may comprise any suitable rigid material such as metal, (i.e. steel). In accordance with at least one embodiment of the invention, each storage strut 30 (i.e. FIGS. 10 and 11) may comprise any suitable base polymer that displays rubber-like elasticity, such as an unsaturated or saturated rubber material including, but not limited to, a nitrile rubber such as a hydrogenated nitrile butadiene rubber (HNBR). The storage struts 30 are configured to dampen rotation and, consequently, engagement noise of the clutch assembly 11. For example, a portion or portions of each storage strut 30 such as the end portion 34 and 36 and/or middle portions 38 of each storage strut 30 may comprise one or more elastomeric materials, and the remainder of each storage strut 30 may comprise a metal, such as the metal steel insert 40.
Generally, each of the storage elements 30 carries resilient material defining the opposite end sections 34 and 36 of the storage element 30. Each storage element 30 is movable between coupling and uncoupling positions between the member 12 and the end wall 28 of the housing part 13. The coupling position is characterized by abutting engagement of the opposite end sections 34 and 36 with respective shoulders of the member 12 and the end wall 28. The uncoupling position is characterized by non-abutting engagement of one of its end sections 34 and 36 with at least one of the members 12 and the end wall 28. Each end section 34 or 36 is configured to deflect or compress upon abutting engagement with respective shoulders of the member 12 and the end wall 28.
In other words, each of the storage elements 30 may include the rigid insert 40 and the elastomeric outer covering layer 47 surrounding and bonded to the insert 40. The insert 40 may be a die-casting formed in a metal injection molding (MIM) process. The outer covering layer 47 is then molded over the insert 40. The molding may be a thermoset elastomer or a thermoplastic elastomer (TPE) which combines the rubber-like properties of a thermoset elastomer and the processing characteristics of a thermoplastic.
The above concept uses either a single metal or rigid strut 26 or synthetic rubber strut 30 with a metal insert 40. The material properties of the rubber are stable in hot transmission fluid or oil. A typical range of operating temperatures for the fluid or oil is −30° to 155° C.
A second embodiment of the electromechanical apparatus is generally indicated in FIGS. 12-15 at 15′. Each part of the apparatus 15′ which is similar in form or function to the corresponding part of the apparatus 15 has the same reference number but a single prime designation.
While exemplary embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. For example, the electromechanical apparatus 15 or 15′ of the exemplary clutch assembly may be carried by a driving member of the clutch assembly or a driven member of the assembly. Moreover, the strut of the exemplary clutches assemblies may have any suitable configuration depending on whether the assembly is a planar coupling assembly as shown herein or a rocker coupling assembly (not shown). Also, each strut or rocker (in a radial coupling assembly) may have a middle portion that is thicker than each end portion of the strut or rocker.
The above noted designs may eliminate the need to keep backlash low which leads to lower stress (higher durability), which leads to lower cost race materials like Aluminum or FC208 PM.
Also, while a preferred base polymer is identified above as HNBR, other acceptable materials include but are not limited to fluoroelastomers, carboxylated nitrile butadiene rubber, nitrile butadiene rubber and ethylene acrylic rubber.
