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 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: An improved differential for a vehicle is provided which includes a disconnect assembly engaged between a ring gear and pinion gears and/or a gear nest associated with the pinion gears, wherein the disconnect assembly is able to disconnect torsional loading of torque between the ring gear and the pinon gears of the differential. The disconnect assembly selectively connects and disconnects the ring gear and pinon gears by preferably disconnecting from the gear nest disposed therebetween. Disconnection of the ring gear and pinion gears allows the ring gear, differential housing, bearings, and rest of the gear box to stop spinning while the wheels of the vehicle are spinning. The differential pinion gears are mechanically connected to the gear nest such that torque can be transferred from the differential gear nest to the differential pinion gears and then to the differential side gears. A spline ring is supported inside the differential housing and defines a mechanical connection which locks the ring gear and the gear nest to transfer torque therebetween, wherein the mechanical connection may be disconnected to unlock the ring gear and gear nest and disconnect such torsional loading to permit rotation of the side gears and pinion gears independent of the ring gear.
