Abstract

An electronic drive unit includes a case housing that extends along a primary axis. A sleeve shaft and an electric motor are disposed in the hollow interior of the case housing. The electric motor is operatively connected to the sleeve shaft to rotate the sleeve shaft about the primary axis. At least one gear set is disposed in operative engagement with the sleeve shaft and is configured for rotation about the primary axis. A pair of output shafts each extends along the primary axis within the case housing. The output shafts are rotatably connected to the gear set and are configured for rotation about the primary axis. The gear set is configured to translate rotation of the sleeve shaft into rotation of the output shafts about the primary axis at a rotational velocity that is less than the rotational velocity of the sleeve shaft.
