Claim Text:
1. An electric drive module for transferring torque to wheels of an electric or hybrid motor vehicle, comprising: a housing defining a motor chamber and a gearbox chamber disposed adjacent to one another and arranged along a common axis; an electric motor including a rotatable rotor disposed in the motor chamber; a first input member driven by the rotor in response to an energizing of the electric motor; a first output member; a two-speed module disposed in the gearbox chamber and drivingly interconnecting the first input member and the first output member at one of two different drive ratios, the two-speed module including a planetary gearset disposed adjacent the electric motor and a synchronizer, the synchronizer being operable to restrict one member of the planetary gearset from rotation when the two-speed module operates at a first drive ratio, the synchronizer transferring energy from the rotating rotor during a shift between the first drive ratio and a second drive ratio to match the rotational speeds of the rotor and the first output member; a reduction unit including a second input member being driven by the first output member and further including a second output member being driven at a reduced speed relative to the second input member; a differential assembly having an input driven by said second output member, a first differential output driving a first output shaft, and a second differential output driving a second output shaft, a shift sleeve slidably attached to the synchronizer for moving the two-speed module axially between the first drive ratio and the second drive ratio, a shift fork extending radially from the shift sleeve for axially moving the shift sleeve between the first drive ratio and the second drive ratio, and an actuator rod attached to the shift fork for moving the shift fork axially.
