摘要： In a driven axle assembly (12) for a motor vehicle that includes a differential housing located substantially in the center of the axle and tubes (16, 17) extending laterally from the differential, surrounding axle shafts (20) and opening into a lubricant reservoir (60) in the differential housing, a system for circulating and cooling axle lubricant includes a cover (26) for closing and sealing the housing having a first aperture into the housing where a ring gear rotates through the lubricant reservoir. The aperture in the cover opens to a chamber that holds lubricant carried through the aperture by the rotating ring gear. Conduit (72) connected by a hydraulic fitting to the chamber has its opposite end connected to an oil cooler mounted on the axle tube. Conduit (78) returns the lubricant to the reservoir in the differential housing. Lubricant flows via a gravity feed through the first conduit into the cooler and back to the housing reservoir via the second conduit, effectively cooling the lubricant without the addition of a pump.

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.
