ABSTRACT:
An annular resilient pivot bushing is described which is suitable for connecting a vehicle suspension link to a vehicle body. The bushing provides greater resistance to linear movement of the suspension link in one direction than to linear movement in the opposite direction. In the preferred construction, this is achieved by using an outer tubular shell for the bushing which has inwardly extending flutes on one of its sides and an intermediate elastomeric element that is similarly fluted. When used in a vehicle suspension system the differential in resiliency prevents a resonant condition from developing that might otherwise cause vehicle body shake.
