Abstract
An inertia balanced, power regenerative transmission system for vehicles augments the power of the prime mover to the transmission output shaft during acceleration and recovers power from the drive shaft during deceleration. The transmission system includes torque sensitive gearing subsystems for transferring power intermediate a flywheel, the prime mover and the drive shaft. A decrease in rotational velocity of the prime mover output shaft and an accompanying decrease in kinetic energy of the vehicle is inherently coupled to increase the rotational speed and attendant kinetic energy of the flywheel, which energy is immediately available upon renewed acceleration of the vehicle.
