ABSTRACT:
A suspension system for a vehicle which maintains the chassis at a constant height above the axle under varying conditions of load. Torsion spring means are employed in conjunction with a support beam that is secured to the chassis. One primary torsion spring has its external shell connected to the axle housing of the vehicle while the remaining torsion spring means has a radially disposed plate means in alignment with a radially disposed plate means extending from the shell of the one primary torsion spring. An inflatable bladder positioned between the plates is controlled by control means which maintains the chassis at such constant height by pressurizing the bladder to a pressure to maintain such height under variable conditions of load.
