Beschreibung
Zusammenfassung:	An electric drive module for transferring torque to wheels of a motor vehicle a planetary gearset having a first member driven by the rotor and a second member. A synchronizer restricts a third member of the planetary gearset from rotation when the electric drive module operates at a first drive ratio. The synchronizer transfers energy from the rotating rotor to the third member during a shift between the first drive ratio and a second drive ratio to match the rotational speeds of the rotor and the second member. A reduction unit includes an input member being driven by the second member and also includes an output member driven at a reduced speed relative to the input member. A differential assembly includes an input driven by the output member, a first differential output driving a first output shaft, and a second differential output driving a second output shaft.
