Abstract
A vehicle drive assembly includes an integrated two-speed motor that can selectively drive an output at a high operating speed or a low operating speed. The two-speed motor includes a stator mounted to a non-rotating outer housing, and a rotor that is mounted for rotation relative to the stator. The rotor is supported an inner rotor support that defines an inner cavity. A two-speed shifting mechanism is incorporated into the inner cavity and is used to drive an output. The two-speed shifting mechanism includes a gear assembly and first and second clutch assemblies that cooperate with each other to provide low and high speed output capability as needed.
