Abstract
A bushing for use in an axle/suspension system of a heavy-duty vehicle. A beam supports an axle for pivotal movement with a hanger of the heavy-duty vehicle at a pivot connection. A bumper is fixed to the beam and contacts an engagement member of the heavy-duty vehicle to limit the relative pivotal movement of the beam and axle in one direction. A force is applied to the pivot connection in a force application direction that is angularly spaced from horizontal and vertical planes. The pivot connection includes a bushing to connect the beam and the hanger. The bushing includes an elastomeric bushing body with at least one void for decreasing rigidity of the bushing body in a substantially vertical direction. The one void is located in the bushing body angularly spaced from the force application direction. The bushing body is substantially solid along the force application direction.
