Two speed gear reducer for electric drive module

An electric drive module (EDM) for an electrified vehicle is provided. The EDM includes a housing; an electric motor; a single compound planetary gear set having a sun gear fixed to its input shaft, a single planetary carrier rotationally supporting pairs of compound planets in engagement with the sun gear and a ring gear, respectively; and first and second torque transfer devices (TTDs) coupled to the carrier. An output of the motor is connected to the input shaft and an output of the EDM is connected to a final drive gearset. The EDM is selectively switchable among: (i) a first gear where the first TTD is disengaged and the second TTD is engaged grounding the carrier to the housing, and (ii) a second gear where the second TTD is disengaged and the first TTD is engaged to couple for common rotation the carrier and the sun gear.
