Abstract
A clutch mechanism is disclosed for use with a hybrid electric vehicle wherein the electric motor/generator and engine are arranged in a series configuration. The clutch mechanism is positioned between and in communication with the electric motor/generator and engine to allow the electric motor/generator to either: 1) provide sole motive power to the vehicle; 2) start the engine; 3) charge the vehicle's battery; 4) provide a power boost; or 5) provide regenerative braking. The clutch mechanism includes an outer race, an inner race, a roller set positioned between the inner and outer races, and a roller cage positioned adjacent the roller set to contain the roller set. The electric motor is preferably an integrated electric motor and generator. The engine is preferably a combustion engine.
