Patent ID: 10323739

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.
