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 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: Methods, devices and systems are provided for determining a connection state of an all wheel drive (AWD) assembly in a vehicle. The method includes receiving, by a vehicle, a message indicative of a hazard and a hazard location on the road and determining a distance to the hazard location from the vehicle. In response to the distance to the hazard location being below a first threshold distance, a state for an AWD assembly in the vehicle is set to a connect state. In response to the distance to the hazard location being above the first threshold, the time for the vehicle to reach the hazard location is determined. If the time to the hazard location is below a threshold AWD connection time, the state for the AWD assembly is set to the connect state.

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.

Abstract: A locking differential assembly includes a differential case, a first output shaft and a second output shaft. A first side gear is non-rotatably coupled to the first output shaft and a second side gear is non-rotatably coupled to the second output shaft. A differential pin is also included, the differential pin having differential gears. The differential gears are rotatably supported by the differential case and drivingly engaged with the first and second side gears to allow differential rotation thereof. A lock mechanism is actuated when a first torque force is applied to a drive cam and a driven cam. Finally, an electromagnetic coil actuates a brake plate, wherein the brake plate comes into frictional with a brake disc. Furthermore, the electromagnetic coil is discontinuous around the circumference of the brake disc.
