Abstract: A limited slip differential assembly can include a sleeve, a support shaft, and a clutch assembly. The sleeve can have a sleeve aperture centered on and extending along an axis. The sleeve can also have a first set of splines projecting inwardly from the sleeve aperture. The sleeve can be operable to engage an axle through the first set of splines. The support shaft can have an outer surface, a support shaft aperture centered on and extending along the axis, and a second set of splines projecting from the outer surface. The support shaft can be adjacent to the sleeve along the axis and be operable to encircle and freely rotate relative to the axle. The clutch assembly can be operable to selectively interlock the sleeve and the support shaft.

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.

Abstract: A limited slip differential assembly includes a planetary gear assembly, a differential case, a differential gear assembly and a hydraulic clutch assembly. The differential case is coupled for rotation with a portion of the planetary gear assembly. The differential gear assembly is arranged within the differential case and includes a first side gear and a second side gear for coupling with first and second drive wheels of a vehicle, respectively. The hydraulic clutch assembly includes a clutch pack and a clutch actuator. Pressurized hydraulic fluid from a transmission pump is selectively provided to the clutch pack to actuate the clutch pack between an open configuration, in which the side gears rotate independently, and a fully closed configuration, in which the side gears rotate together such that the first and second drive wheels rotate at a same speed.
