摘要： A fluid pump assembly comprises a pump housing and a fluid pump disposed within the pump housing. The fluid pump has axially opposite first and second side faces and includes cooperating impeller and rotor members. The fluid pump assembly further comprises inlet and outlet ports disposed adjacent to the first side face, a pressure chamber formed within the pump housing adjacent to the second side face, and an end plate disposed within the pressure chamber and movable relative to the pump between a first position and a second position. The end plate has axially opposite inner and outer end surfaces oriented so that the inner end surface faces the fluid pump, while the outer end surface faces away from the pump. An area of the outer end surface of the end plate is greater than the area of the inner end surface thereof.

摘要： A drive system designed to use a vehicle's existing hydraulic system to operate a controllable limited slip differential assembly. The limited slip differential assembly may be associated with the front axle, the rear axle, or the driveline between the front and rear axles. The differential assembly may also be used in combination that includes front, rear, or intermediate differential assemblies. The drive system further includes a friction clutch assembly for selectively engaging and disengaging an input member with an output member of the differential assembly, a fluid clutch actuator for selectively frictionally and variably loading the clutch assembly, and a fluid pump that is a common source of pressurized fluid for the fluid clutch actuator and the existing hydraulic system of the motor vehicle other than the fluid clutch actuator of the drive system. The fluid clutch actuator is actuated by fluid pressure generated by the fluid pump.
