Patent ID: 8123656

Claim:
A hybrid transmission for use with an engine, comprising: an engine connection member configured for connection with the engine; an electric motor; a transmission gearing arrangement; a transmission input member connected with the transmission gearing arrangement; a torque transfer device controllable to transfer torque from the motor to the transmission input member upstream in power flow from the mechanical transmission gearing arrangement; a disconnect clutch selectively engagable to operatively connect the engine connection member with the motor to permit the motor to start the engine; a one-way clutch having a first rotatable element continuously connected for rotation with the engine connection member and a second rotatable element continuously connected for rotation with the motor at a common speed and configured to overrun when the second rotatable element rotates faster than the first rotatable element; and wherein the disconnect clutch is arranged in parallel with the one-way clutch; the one-way clutch thereby carrying torque when the engine powers the transmission and overrunning when the motor powers the transmission.
