  • Means for propelling a wheeled vehicle
    Patent number: 4133403
    Abstract: Electric motors are connected to the front wheels of a vehicle to commence the propulsion of the vehicle. Fluid pressure motors are connected to the rear wheels of the vehicle to propel the vehicle once the electric motors have commenced the propulsion thereof. An electric pump supplies expansible fluid to the fluid pressure motors. Electric heaters expand the fluid in the fluid pressure motors to cause the fluid pressure motors to rotate the rear wheels of the vehicle thereby propelling the vehicle. The electric motors are adapted to act as generators after the fluid pressure motors have commenced the propulsion of the vehicle to recharge a battery that operates the electric motors, the electric pump and the electric heaters.
