Abstract: A differential system for a front wheel drive vehicle. The differential system includes a differential carrier (24), an actuator housing {44), an intermediate shaft (32), a clutch pack (42), and a piston (40). The differential carrier (24) houses a differential assembly (16) configured to drive a right and left axle shaft. The actuator housing (44) is configured to rotate in conjunction with the differential carrier (24). The intermediate shaft (32) extends through the actuator housing (44). The clutch pack (42) has a first set of clutch plates (46) that engage the actuator housing (44} and a second set of clutch plates (48) that engage the intermediate shaft (32). The piston (40) compresses the first and second set of clutch plates {46, 48) thereby frictionaiiy coupling the differential carrier (24) to the intermediate shaft (32) and thus locking or modulating the differential.

Abstract: The present invention relates to a clutch actuation mechanism having a valve, a plurality of couplings in fluid communication with the valve, wherein one of the plurality of couplings is operable to distribute power between a primary set of wheels and a secondary set of wheels, and another of the plurality of couplings is operable to distribute power between each of the secondary set of wheels. The present invention also includes a drive shaft driven by a source of power, which is also connected to the secondary set of wheels, and a pressure supply device in fluid communication with the valve, wherein the valve directs fluid to the plurality of couplings, and when the valve directs fluid to the one of the plurality of couplings operable to distribute power between the primary set and secondary set of wheels, the drive shaft will transfer power to the secondary set of wheels.
