ABSTRACT:
A suspension and auxiliary power system for a vehicle having a frame, a power consuming load on said frame, and at least one supporting wheel which is adapted to move vertically relative to the frame. The system includes a fluid pump connected between the frame and the wheel and including a piston which is reciprocated in response to relative movement between the frame and wheel to contract or expand a fluid chamber. A fluid circuit connected to the pump includes a uni-directional fluid motor which drives a power consuming load. The fluid circuit is connected to the fluid chamber of the pump and includes a check valve for permitting fluid to flow only from the chamber directly to the motor. A second check valve in the circuit regulates flow so that fluid is directed only from a source of fluid to the chamber. The fluid pump acts as a hydraulic suspension system supporting at least a part of the vehicle weight whereby loading of the motor causes the motor to serve as a shock absorber for the pump.
