摘要： A power transfer unit (PTU) for a motive device includes an outer housing and a torque transferring clutch. The PTU also includes a piston housing located between the outer housing and the torque transferring clutch, and a piston in the piston housing. The piston is arranged to provide actuation forces to the torque transferring clutch, and to restrict reaction forces back to the piston housing.

摘要： A power transfer unit for a motive device comprises an outer housing, an inner housing, and a torque transferring clutch. A piston housing is located between the outer housing and the torque transferring clutch. A piston is located in the piston housing. The piston is configured to provide actuation forces to the torque transferring clutch. And, when the torque transferring clutch receives the actuation forces, the torque transferring clutch causes the inner housing to rotate.

摘要： A wrap spring activated torque coupling is applied to a torque transmission coupling and/or a locking differential for a motor vehicle. The wrap-spring torque coupling allows for quick engagement and disengagement of an input member to an associated output member at large torsional capacities that exceed the limit of what is taught by prior art. The ability to quickly lock and unlock a vehicle differential under either a torsionally loaded or unloaded condition is realized by this application of the wrap spring activated torque coupling. Moreover, a two piece bi-directional wrap spring hub design is utilized that allows for simple turning and broaching operations for use in its manufacture, thereby eliminating a conventional deep annular counterbore that would require the use of much more expensive machining processes.

摘要： A hydraulically actuated torque-coupling device is provided for selectively actuating a secondary drive axle of an All-Wheel Drive motor vehicle when wheel slippage occurs with a primary axle. The torque-coupling device comprises a housing, an input shaft and an output shaft both rotatably supported within the housing, a selectively engageable friction clutch assembly for operatively coupling the input shaft to the output shaft, and hydraulic clutch actuator. The hydraulic actuator includes a hydraulic pump located within the housing and adapted to generate a hydraulic pressure to frictionally load the friction clutch assembly, and a variable pressure relief valve assembly fluidly communicating with the hydraulic pump to selectively control the hydraulic pressure generated by the pump. The variable pressure relief valve assembly includes an electro-magnetic actuator for selectively varying a release pressure of the pressure relief valve assembly based on a magnitude of an electric current applied thereto.
