Abstract

The power train of a motor vehicle has an engine which normally drives the wheels and can be started by an electric motor which acts as a generator once the engine is started. The torque transmitting connection between the crankshaft of the engine and a shaft of the motor includes a planetary and one or more freewheels of the type employing an elongated belt surrounding a rotary part and being surrounded by the internal surface of a hollow part. The belt or belts can be urged into or released from frictional engagement with one of the adjacent surfaces by centrifugal force and/or by an electromagnet.
