ABSTRACT:
An elongate metal cross-member is connected to and extends transversely across a vehicle frame. A pair of elongate composite control arms are connected to opposite ends of the cross-member by mounting mechanisms which control and guide the flexing of the control arms to prevent failure thereof. Wheel hub assemblies are connected to the outer ends of the control arms. A shock absorber is connected between each one of the wheel hub assemblies and the vehicle frame to dampen oscillations. The control arms may be made of reinforcing glass or graphite fibers held together with a thermoset resin binder and formed by the pultrusion process.
