Planetary differential drive system
A differential drive system includes an electric motor for generating an electric motor torque and an input planetary gear-set operatively connected to the electric motor to receive the electric motor torque. The input planetary gear-set has first, second, and third members. The first member receives the electric motor torque, the second member provides a first input torque in a first rotational direction in response to the electric motor torque, and the third member provides a second input torque in a second rotational direction, opposite the first direction, in response to the electric motor torque. The system also includes a first output gear-set operatively connected to the input planetary gear-set, and providing a first output torque in response to the first input torque. The system additionally includes a second output gear-set operatively connected to the input planetary gear-set and providing a second output torque in response to the second input torque.
