Abstract
A drive train module with an electric motor, a clutch differential, a pair of wheel hubs and a pair of shafts, which rotatably couple the wheel hubs to the clutch differential. The clutch differential can have an input member, which can be coupled to an output shaft of the motor, and first and second overrunning clutches. The overrunning clutches permit the electric motor to drive the wheel hubs when the drive train module is activated to provide supplemental drive power, and to prevent the electric motor from being back-driven by the wheel hubs when supplemental drive power is not desired.
