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.
