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 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 differential includes a differential case; a side gear; a pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole. In embodiments, the pinion housing includes one or more transfer formations configured to transfer torque from the differential case, and the pinion housing is configured to permit movement in an axial direction between a pair of side gears.

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.
