Abstract: A method of providing limited slip in a differential assembly includes interconnecting an axle and a differential assembly through a first slippable linkage. The axle is driven in rotation with a first housing of the differential assembly operable to be driven in rotation by a ring gear. A plurality of pinion gears of the differential assembly are positioned in the first housing and are driven in rotation by the first housing. A side gear is fixed to the axle and is meshed with at least some of the pinion gears. The axle is operable to slip relative to the first housing. The first housing, the plurality of pinion gears and the side gear are enclosed within a second housing. The axle extends from a first end positioned within both of the first housing and the second housing to a second end positioned outside of both of the first housing and the second housing.

Abstract: A differential gear mechanism configured for use with a transaxle housing includes a limited-slip differential assembly including a differential casing defining first and second output shaft openings that receive respective first and second axle shafts. A piston is slidably disposed in the differential casing and configured to actuate a clutch assembly. A bolt-on plenum assembly is configured to bolt onto the transaxle housing and includes a plenum assembly housing, a hydraulic coupling and a motor. The plenum assembly housing defines an axle opening configured to receive one of the first and second axle shafts therethrough. The hydraulic coupling can be arranged on the plenum assembly housing at the axle opening. The motor can be mounted on the plenum assembly housing at the axle opening and be configured to pump hydraulic fluid from the bolt-on plenum assembly, through the hydraulic coupling and into the differential casing to act onto the piston.
