ABSTRACT:
A plurality of interconnected air bag assemblies suspend a frame above a vehicle axle or similar support member to provide a low vertical spring rate and a high roll spring. The air bag assemblies comprise a pair of air bags and a piston suspended therebetween. In one preferred embodiment a net effective area which decreases with upward movement of the piston combines with an air bag interconnection system to provide the desired spring rates. Alternate embodiments use offset connection in place of, or in conjunction with the tapered pistons. The air bag assemblies of tandem axles are interconnected to provide equalization in a preferred embodiment.
