    Abstract: A differential gear includes a differential casing having a first differential case portion that defines a first output shaft opening and a second differential case portion that defines a second output shaft opening. The first differential case portion can include an annular pocket formed thereon and defined by an outer circumferential wall, an inner circumferential wall and an end wall. A piston can be slidably disposed in the annular pocket and configured to actuate a clutch assembly. A first and a second side gear can be rotatably mounted within the differential casing. The first and second side gears can be co-axially aligned along an axis of rotation of the differential casing.

    Abstract: A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a sump and a motor. The hydraulic control unit housing has an accumulator housing portion that houses a biasing assembly and a piston. The sump is defined in the hydraulic control unit housing and at least partially occupies a common space with the accumulator housing portion. The motor is configured to pump fluid into an accumulator chamber of the accumulator housing portion. The fluid pumped into the accumulator housing portion at least partially collapses the biasing assembly and introduces a pre-charge into the hydraulic control unit. The biasing assembly is configured to expand and urge the piston in a first direction resulting in fluid being communicated from the hydraulic control unit and into the limited slip differential.

    Abstract: A clutch system selectably connects a vehicle rear axle to a motor. The clutch system includes an intermediate shaft to fixably attach to a side gear of a differential for rotation therewith. A case of the differential is connected to the motor via a gear train. Another side gear of the differential is affixed to an output shaft, and the output shaft extends through a center of rotation of an armature of the motor to connect to a road wheel of a vehicle. A clutch is to selectably connect the intermediate shaft to another output shaft connected to another road wheel of the vehicle. An actuator is to actuate the clutch to an engaged state and thereby selectably connect the intermediate shaft to the other output shaft. The output shaft, the other output shaft, and the motor rotate independently when the clutch is not in the engaged state.
