Abstract: A system for absorbing vibration created by operation of an engine of the present invention includes a first plate driven by an engine shaft and a torque transmitting device for transferring torque from the engine shaft to a transmission input shaft. The system includes a first vibration absorber and a second vibration absorber. The first vibration absorber includes at least one selectively moveable mass. The second vibration absorber includes at least one biasing member and generally opposing ends. The first vibration absorber is configured to absorb vibrations created at a first harmonic of the engine and the second vibration absorber is configured to absorb vibrations created at multiple harmonics of the engine.

Abstract: An electric vehicle drive system includes an electric motor, first and second planetary gear sets, including sun gear, carrier and ring gear members, first and second output shafts, and a housing. The members of the first planetary gear set are connected with the electric motor, the first output shaft, and a member of the second planetary gear set. The members of the second planetary gear set are connected with the first planetary gear set, the housing, and the second output shaft. The first planetary gear set provides differential reduction and the second planetary gear set provides reversal and reduction. Optional clutches can provide the function of a limited slip differential and distribute torque preferentially to one output shaft or the other.
