ABSTRACT:
A vehicle having a plurality of ground engaging wheels has included, in at least one of said wheels, a hydraulic pump/motor device. The hydraulic fluid for the pump/motor device is stored in a toroidal tire portion of the wheel while the pump/motor is disposed in a hub portion of the wheel. The hydraulic fluid is drawn from a sump reservoir in the tire portion and is pumped to a high pressure liquid/gas accumulator in the tire portion during vehicle braking. When desired, the high pressure fluid is returned through the pump/motor to the sump reservoir during which time the energy of the high pressure fluid is delivered to the vehicle through the motoring action of the pump/motor.
