The differential includes a third element operatively connected to a fly wheel. The fly wheel and prime mover are arranged to simultaneously drive said output shaft through said differential so that the speed of the vehicle may remain constant or vary regardless of the speed of the fly wheel. The fly wheel is capable of being driven by a source external of the prime mover so that the fly wheel may assist the prime mover during acceleration of the vehicle.Other References
