Abstract
A suspension module with a suspension component, wheel hubs coupled to the suspension component, and a drive system. The drive system has a pair of units that selectively provide drive torque to an associated one of the wheel hubs. Each unit includes a motor, a first reduction gearset and an overrunning clutch. The first reduction gearset is disposed between the motor and its wheel hub and multiplies torque output from the motor. The clutch disconnects the motor from the associated wheel hub so that an output shaft of the motor is not drivingly coupled to the associated wheel hub when a rotational speed of the first portion does not exceed a rotational speed of the second portion. The clutch can be selectively operated to drivingly couple the motor to its wheel hub to permit the motor to be back-driven. A method for operating a hybrid power train is also provided.
