Abstract: A secondary drive unit (SDU) for the secondary axis of an all wheel drive vehicle consists of an SDU housing defining a first section for receiving a main shaft which is connected to a drive source and a second section for enclosing a twin clutch assembly. The twin clutch assembly has a common clutch housing connected to the main shaft, a left clutch for selectively connecting a left output shaft and the clutch housing, a right clutch for selectively connecting a right output shaft and the clutch housing, and a rigid center plate separating the left and right clutches. The twin clutch assembly may be activated by a dual action piston assembly to decrease all wheel drive synchronization and connection response times.

Abstract: A rear drive module for an all-wheel drive motor vehicle includes a differential assembly having an outer differential housing and an inner differential housing, the inner differential housing being fixed for rotation with an output shaft of the differential assembly; a ring gear assembly having a ring gear mounted to and fixed for rotation with the outer differential housing; and a disconnect and synch-lock mechanism: operable to synchronize and lock the inner differential housing and the outer differential housing, and to disconnect the inner differential housing and the outer differential housing to prevent rotation of the outer differential housing and the ring gear. The disconnect and synch-lock mechanism may include a synchronizer clutch and a clutch actuator. The clutch actuator may be a ball-ramp or face cam mechanism which is configured to control the operation of the synchronizer clutch and locking between the inner and outer differential housings.
