Abstract
A transmission having a starter/generator that is not mounted on the engine crankshaft is provided. The starter/generator is drivingly or directly connected to a transmission pump, and can selectively engage a torque converter and/or an internal combustion engine. The invention allows for efficient disengagement of the engine when the vehicle is stopped, and reengagement upon subsequent torque demand.
Claims19
A power train for a motor vehicle, comprising:
- an internal combustion engine;
- a starter/generator having a rotor;
- a torque converter having an input impeller, an output turbine, and a stator having a housing;
- a transmission pump having a cover and being directly connected to the rotor such that the pump can receive power directly from the rotor;
- a transmission input directly connected to the output turbine of the torque converter;
- a selectively engageable clutch disposed between the starter/generator and the internal combustion engine;
- the internal combustion engine being operatively connected to the input impeller of the torque converter;
- and
- the rotor of the starter/generator being operatively connected to the input impeller of the torque converter.
