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 clutch assembly includes a clutch hub, a clutch drum disposed about the clutch hub, a first gear connected to the clutch drum, the first gear configured to be coupled with a first shaft, the clutch hub configured to be coupled with a second shaft, a clutch pack disposed between the clutch hub and the clutch drum, and an air-actuated piston assembly for selective actuation of the clutch pack to connect or disconnect two drive axles in a tandem axle assembly. The clutch assembly includes a plurality of lever arms disposed between the piston assembly and the clutch pack. Each lever arm extending to engage the piston and the clutch pack. Each lever arm may be pivotally mounted to a lever carrier plate or to a fixed portion of the piston housing.
