IH Air Suspension 700869

A new truck air suspension system has been developed which provides excellent roll stability and articulation capability without compromising the exceptionally soft ride characteristics of air suspension. The concurrent realization of roll stability and articulation capability for tandem driving axles has been achieved by designing a nearly rigid, roll resisting, rear axle, to be used in conjunction with a freely articulating, forward rear axle. This principle applies equally well for single driving axle vehicles, where the rigid axle provides the same roll stability while articulation, not really a problem on single axle vehicles, is provided by frame and front axle suspension flexibility.
