ABSTRACT:
An air suspension system for each rear wheel of van-type vehicles features a seven-point articulated system. A pair of rearwardly diverging torque rods are pivotally attached to the axle hanger to provide a modified parallelogram linkage. The angle of divergence is set by an adjustable torque rod pivot point and an automatic pneumatic height restoration feature to dispose the torque rods at optimum orientation to provide, among other things, a measure of anti-rise action on braking. A pair of air springs mounted on articulated carrier arms carries the weight of the vehicle without the use of assisting springs. Anti-sway is provided by specification of elastic rates of bushings in pivots providing the articulation of the system.
