ABSTRACT:
A distributed compliance air-ride axle/suspension system includes an integral structure preferably formed of a lightweight composite material, replacing traditional beams and an axle. The composite structure includes a plurality of plates of various sizes and shapes, with the size, shape and arrangement of the plates being determined by the load capacity model of a specific vehicle application. Traditional axle spindle ends are mounted on the integral plate structure, together with pivot bushings, air springs, and shock absorbers, to complete the air-ride axle/suspension system. The system in turn is pivotally mounted on frame brackets of a heavy-duty vehicle such as a semi-trailer or dump truck. Forces, loads and/or stresses imposed on the axle/suspension system during vehicle operation are distributed generally throughout the composite structure to achieve the desired structural roll compliance of the axle/suspension system for the particular application.
