ABSTRACT:
A roller bushing assembly for use in a vehicular leaf spring suspension system pivotally supports an end of a leaf spring so as to minimize transmission of roadway induced shock and vibration loads to the vehicle and driver. The roller bushing assembly includes a tubular housing containing roller bearings for support of a shaft which is connected to a vehicle chassis. Free flexure of the spring is facilitated by providing low friction pin connections that minimize resistance of the vehicle/spring connections to rotation of the spring ends and extension and contraction of the spring. A method of installation of a bushing having bearings therein includes supporting the bearings on a pilot and force-fitting the tubular housing into a spring eye with a pressing tool. After removal of the pilot from the bearings, the shaft is inserted into the bearings and seals are slid along the shaft to abut and seal the bearings against intrusion of foreign matter.
