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 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.

Abstract: Disclosed is a locking differential assembly which includes a differential case, a first output shaft and a second output shaft. Further included is a first side gear non-rotatably coupled to the first output shaft and a second side gear 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. Also included is a locking mechanism, the locking mechanism being actuated when a first torque force is applied to a drive cam and a driven cam. Finally included is an electromagnetic coil. The electromagnetic coil actuates a brake plate, the brake plate comes into frictional with a brake disc. Furthermore the electromagnetic coil is discontinuous around the circumference of the brake disc.
