摘要： A bi-directional overrunning clutch assembly employed in connection with a reduced capacity low friction clutch to provide low and reverse gears in a transmission. The clutch assembly including an inner race, an outer race, and engagement members supported therebetween. The inner race is operatively coupled to the transmission casing and the outer race is operatively coupled to the ring gear of the gear set as well as the inner race of the friction clutch assembly. The clutch assembly further includes at least one actuating cam. The actuating cam operates to actuate the engagement members to provide four separate modes of operation between the inner and outer races of the clutch assembly. More specifically, the cam is operable to (1) disengage the engagement members to provide freewheeling between the inner and outer races in both rotational directions; (2) to actuate engagement members so that torque is translated in one rotational direction but to allow freewheeling in the opposite rotational direction; (3) to actuate the engagement members so that torque is translated in a direction opposite to that in mode (2) above, but allow freewheeling in the rotational direction opposite to that in which torque is translated in this mode; and (4) to actuate the engagement members so that the inner and outer races are locked relative to each other and torque is translated in both rotational directions.

摘要： Pursuant to the control strategy of the present invention, torque load may be shared between the low/reverse friction clutch and a one-way clutch to effect low and reverse gear ratios in a transmission. This may be accomplished by engaging the friction clutch during vehicle launch and keeping it engaged until the peak torque has passed. Once the peak torque has been passed, the load capacity of the friction clutch can be reduced to zero. In this operational mode, the one-way clutch is acting to support the remaining drive torque. Thus, with only the one-way clutch carrying a load at the time of the up-shift from first to second gear, a non-synchronous shift can be affected. In this way, the control strategy acts to share the torque load between the low/reverse brake and the low one-way clutch, thereby allowing a reduced capacity, lower spin-loss one-way clutch design.
摘要翻译：根据本发明的控制策略，可以在低/反向摩擦离合器和单向离合器之间共享扭矩负载，以实现变速器中的低速和低速传动比。这可以通过在车辆发射期间接合摩擦离合器并保持其接合直到峰值扭矩已经达到来实现。一旦峰值扭矩已经通过，摩擦离合器的负载能力可以减小到零。在该操作模式中，单向离合器用于支撑剩余的驱动扭矩。因此，只有单向离合器在从第一档向上变速时承受负载时，可能会影响非同步档位。以这种方式，控制策略用于共享低/反制动器和低单向离合器之间的转矩负载，从而允许减小容量，降低自旋损耗单向离合器设计。

摘要： A friction device includes drive and driven members rotatable about a common axis and defining a housing therebetween in which a piston assembly is supported and an expandable chamber is defined. A clutch pack is interposed between the drive and driven members and has separation plates interleaved with friction plates. The piston assembly is adapted to move among disengaged, pre-staged, and engaged positions wherein the friction plates are disposed in non-contacting, proximate contacting, and contacting relationship, respectively, with the separation plates. In the engaged position, the piston assembly is disposed forcing such contacting relationship to actuate the clutch pack to connect the drive and driven members. The clutch pack further has a separation device disposed between adjacent friction plates and adapted to bias the adjacent friction plates in opposite directions to facilitate non-contacting rotation of the adjacent friction plates when torque translation between the drive and driven members is interrupted.

摘要： A friction device includes a clutch pack operable to connect and disconnect drive and driven members for transferring and interrupting torque therebetween. A piston is supported in the clutch housing and defines a first expandable chamber. The piston is responsive to the pressure of fluid in the expandable chamber to move between disengaged and engaged positions thereby actuating the clutch pack. An outer ring is slidably supported within the housing to form a second expandable chamber. The outer ring includes at least one orifice extending therethrough. The piston closes the orifice in the outer ring when the drive and driven members are disconnected and has a second position where the orifice is open. A second source of lubricant pressure separate from the piston actuating fluid flows into the second expandable chamber thence through the orifice and from the outer diameter of the clutch pack between the adjacent plates and disks to the inner diameter of the clutch pack for cooling the pack.

摘要： A clutch assembly (10) having an inner race (12), an outer race (14), and an engagement mechanism (16) disposed between the inner and outer races. The engagement mechanism (16) is operable to move between a disengaged position wherein the inner and outer races may freely rotate in one direction relative to one another and an engaged position wherein in the inner and outer races are locked so as to translate torque therebetween in the opposite rotational direction. The inner race (12) and outer race (14) may be defined by a plurality of plates (18, 12) and layers of elastomer (20, 24) that are disposed between adjacent plates in laminated fashion. The inner race and/or outer race may further include at least one bearing surface through which a force may be translated. The bearing surface is defined by a plurality of plates (70, 76) that are offset relative to an adjacent plate by a predetermined distance. The elastomeric layer (20, 24) allows movement of the offset plate (70, 76) in the direction of a force acting on the bearing surface such that the offset plates (70, 76) and the elastomeric layers (20, 24) act to absorb energy and dampen noise and vibration when the bearing surface is subjected to a force.

摘要： A bi-directional one-way clutch mechanism with a compliant cage member. The clutch mechanism has a plurality of roller members positioned between inner and outer race members. A compliant cage member is also positioned between the race members and acts to hold the roller members in place and also to reduce the magnitude of loads applied to the roller members when the clutch mechanism is engaged. The roller members are positioned in windows in the cage members and integral spring-like leaf segments are positioned in each of the windows on either side of the roller members. One or two spring-like members, together with one or more recesses between each of the windows and roller members provide resiliency for the cage mechanism. The compliant cage device reduces the magnitude of the loads applied to the clutch mechanism and prevent fatigue fracture and premature failure of the cage device. In an alternate embodiment, a one-piece injection molded compliant cage mechanism is utilized with separate metal spring members for biasing the roller members.
