ABSTRACT:
A vehicle load-leveling system includes a fluid actuated strut connected between the vehicle frame and axle. A piston moves to transfer actuating fluid to the strut in response power steering fluid pressure. A solenoid-controlled spool valve regulates communication of power steering fluid with the piston. Another solenoid-controlled valve assembly controls communication of actuating fluid with the strut. A height sensor cooperates with the solenoids so that selected amounts of actuating fluid are communicated to the strut to maintain the separation of the frame and the axle substantially between a predetermined range.
