ABSTRACT:
An improved shock absorbing and leveling system for vehicles or the like is disclosed and includes a shock absorber sub-assembly and an airspring sub-assembly that can be used as either an assist device for a primary spring or as a primary spring itself. The preferring airspring sub-assembly includes a relatively rigid chamber member and a rolling flexible diaphragm member sealingly interconnected to one another, with an electrical inductance height sensor surrounding the shock absorber and contained substantially wholly within the chamber member. The airspring sub-assembly also preferably includes a diaphragm support member that laterally supports the diaphragm member on the shock absorber housing in a laterally spaced-apart relationship at least at two longitudinal positions thereon. Advantageously, the shock absorber sub-assembly and the airspring sub-assembly are independently removable from one another and replaceable as separate sub-assemblies.
