Abstract
An electrified multiple speed ratio transmission for mounting to an external power-source and transmitting a power-source torque therefrom includes an input member configured to receive the power-source torque. The transmission also includes a torque transfer system configured to receive the power-source torque from the input member and select an input-to-output speed ratio of the transmission. The transmission additionally includes an electric motor operatively connected to the torque transfer system and configured to apply an electric motor torque input thereto. Furthermore, the transmission also includes an output member operatively connected to the torque transfer system and configured to receive the power-source torque and the electric motor torque input therefrom and output a sum of the power-source torque and the electric motor torque input to drive a load. A vehicle having such an electrified multiple speed ratio transmission is also envisioned.
