Abstract
A transmission includes an input member, an output member, a first electric device, and a second electric device. A first planetary gear set is coupled to the first electric device. A second planetary gear set is coupled to the second electric device. The output is coupled to both the first planetary gear set and the second planetary gear set. The input is connected to the first planetary gear set. A fixed ratio gear reduction system couples the input and the second planetary gear set. The fixed ratio gear reduction system is operable to transmit rotation from the input to the second planetary gear set at a reduced rotational speed and at an increased torque.
