Abstract: An improved twin clutch, two-speed disconnect secondary drive unit, which may be configured as a rear drive unit (RDU) for an all wheel drive vehicle is provided. The RDU is driven through an input shaft, which is connected to a vehicle drive source such as a motor, and includes a twin clutch assembly, which is connected to the drive shaft and is selectively actuated to drive left and right main shafts, which drive respective wheels of the vehicle. The RDU further includes a modular a shift assembly mountable to one or both of said main shafts to drive output shafts, wherein each shift assembly is selectively operable between the hi-range and lo-range modes to shift driving operation of the output shafts between hi-speed and lo-speed operation. The shift assembly may be controlled by improved mono-stable or bi-stable actuators.

Abstract: A disconnect system for selectively engaging and disengaging one or more shafts of a power train unit. The disconnect system includes a plurality of cam members and an electromagnetic coil. At least one cam member rotates at the same speed as an input shaft. At least one cam member rotates at variable speeds. In operation, the electromagnetic coil is energized by rotation of the input shaft for selectively activating a clutch to engage one or more of the cams to connect and disconnect one or more output shafts.

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.
