Abstract:
1. A transmission for a vehicle having an engine, comprising: an input member operatively connected to the engine for receiving power from the engine; an output member; a differential gear set having a first member, a second member and a third member and operatively connected between said input member and said output member; and a compound motor/generator having a single stator, a first rotor, and a second rotor; wherein said rotors are axially-spaced adjacent to one another for rotation about a common axis; wherein said first rotor is connected for common rotation with said output member and said second rotor rotates concentrically about said output member; wherein said single stator is operable to provide power to, receive power from and to transfer torque between said first and second rotors; and wherein said first and second rotors are operatively connectable to different ones of said members of said differential gear set such that the transmission is an electrically variable transmission having a mechanical power path and an electromechanical power path.
