    摘要： A one-way clutch assembly includes an inner race adapted to be fixed for rotation with a first rotatable member, an outer race having circumferentially spaced apart cam surfaces and being adapted to be fixed for rotation with a second rotatable member as well as a plurality of roller elements positioned therebetween. A plurality of circumferentially extending springs cooperate with the cage to align each roller element with the cam surfaces. The springs and cage urge the roller elements away from the inner race. A retaining mechanism captures lubricant in contact with the roller elements.

    摘要： A pump system includes pump having a control feature which, responsive to a supply of pressurized working fluid, reduces the pressure of the working fluid pressurized by the pump. The control feature is connected to the output of the pump by a regulating valve. The control feature receives pressurized working fluid to decrease the output of the pump in response to the pressure of the supplied working fluid. A regulating valve selectively connects the pressurized working fluid to the control feature. The regulating valve has a control port to receive pressurized working fluid from the pump to urge the valve to a closed position against a biasing force. A controllable valve is operable to interrupt the supply of pressurized working fluid to control port to alter the output pressure of the pump.

    摘要： A dual clutch powershift transmission for use in a motor vehicle having an engine (12) and a driveline includes an output shaft (28) adapated for connection to the driveline, first (18) and second (20) input shafts, a first engine clutch (14) operable for establishing a releaseable drive connection between the engine and the first input shaft and a second engine clutch (16) operable for establishing a releasable drive connection between the engine shaft and the second input shaft. As first constant mesh gearset (70) is driven by the first input shaft. A second constant mesh gearset (76) is driven by the second input shaft. As first shift clutch (150) releasably engages the first gearset to establish a drive connection between the first input shaft and the output shaft. A second shift clutch (170) releasably engages the second gearset to establish a drive connection between the second input shaft and the output shaft.

    摘要： A transaxle transfers torque to first and second axle shafts. The transaxle includes a main shaft, a planetary gearset, a first clutch transferring torque between the main shaft and a first member of the planetary gearset and a second clutch transferring torque between the main shaft and a second member of the planetary gearset. An input shaft is fixed for rotation with the first member of the planetary gearset. A countershaft is selectively driven by first, second, third and fourth speed gearsets associated with the input shaft. A final drive unit provides multiplied torque to a differential assembly adapted to drive the first and second axle shafts. Actuation of the first and second clutches selectively provides first through eighth discrete forward drive ratios such that each of the first, second, third and fourth speed gearsets transfers torque during provision of two of the first through eighth forward drive ratios.
