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.
