Abstract
A torque converter disposed between a motor/generator and an internal combustion engine during the engine starting procedure and between the motor/generator and a multi-speed transmission as well as between the engine and a multi-speed transmission during vehicle travel. A pair of selectively engageable clutches and a one-way device are incorporated to accomplish the engine start power path, the normal torque converter power path and a converter bypass power path.
Claims1
An electric hybrid powertrain comprising:
- a motor/generator;
- an internal combustion engine;
- a torque converter having an input impeller, a stator and an output turbine;
- a one-way drive mechanism disposed between said motor/generator and said internal combustion engine for permitting power flow from said internal combustion engine to said motor/generator and preventing reverse power flow;
- and
- a selectively engageable friction clutch mechanism for selectively connecting said internal combustion engine with said output turbine for receiving power therefrom, said motor/generator being continuously drivingly connected with said input impeller, said clutch mechanism being engaged and said motor/generator driving said input impeller for delivering power through said torque converter to start said internal combustion engine.
