Patent ID: 8556760

Claim:
An electric drive module for a motor vehicle, comprising: an electric motor; a first input member; a first output member; a two-speed module selectively drivingly interconnecting the first input member and the first output member at one of two different drive ratios; a reduction unit including a second input member being driven by the first output member and having a second output member being driven at a reduced speed relative to the second input member; and a differential assembly having an input driven by the second output member, a first differential output driving a first output shaft, and a second differential output driving a second output shaft, wherein the two-speed module includes a planetary gearset, the first input member including an annulus gear of the planetary gearset and the first output member including a carrier of the planetary gearset, wherein the two-speed module includes a first clutch for selectively driving one of a sun gear and the carrier at the same speed as the annulus gear, a second clutch for selectively restricting rotation of the sun gear to operate the planetary gearset in an underdrive mode, and a spring biasing a member of the first clutch to place the first clutch in a torque transferring mode and operate the planetary gearset in a direct drive mode.
