Abstract

A differential system for a front wheel drive vehicle. The differential system including a differential carrier, an actuator housing, an intermediate shaft, a dutch pack, and a piston. The differential carrier houses a differential assembly configured to drive a right and left axle shaft. The actuator housing is configured to rotate in conjunction with the differential carrier. The intermediate shaft extends through the actuator housing. The dutch pack has a first set of clutch plates that engage the actuator housing and a second set of clutch plates that engage the intermediate shaft. The piston compresses the first and second set of clutch plates thereby frictionally coupling the differential carrier to the intermediate shaft and the locking or modulating the differential.
