Abstract: An automatically-shiftable transaxle includes an input member configured to receive an external power-source torque and rotate about a first axis. The transaxle also includes torque transmitting device(s) and a gear-train, each operatively connected to the input member for selecting transaxle speed ratios, and a first transfer gear operatively connected to the gear-train and rotatable about the first axis. The transaxle also includes an intermediate shaft rotatable about a second axis, and a second transfer gear rotatably fixed to the intermediate shaft and meshed with the first transfer gear. The transaxle additionally includes an electric motor arranged on a third axis for providing a torque input to the second transfer gear. Furthermore, the transaxle includes a differential assembly operatively connected to the intermediate shaft and rotatable about a fourth axis to thereby transmit a transaxle output torque to drive the load. All four transaxle rotational axes are arranged in parallel.

Abstract: A final drive unit for a motor vehicle includes a sprocket driven by a transmission, a first planetary gear set where one of the rotational members is connected to the sprocket, a second planetary gear set where one of the rotational members is connected to the first planetary gear set, and an actuator moveable between a low range position and a high range position. The actuator is rotationally coupled to a differential. When the actuator is in the low range position, the actuator rotationally couples one of the rotational members of the second planetary gear set to the differential. When the actuator is in the high range position, the actuator rotationally couples another of the rotational members of the second planetary gear set to the differential.
