Abstract
A sleeve and bushing assembly for mounting a shock absorber to a motor vehicle and reducing road vibration experienced by the motor vehicle, as well as a method of manufacturing the assembly. The sleeve and bushing assembly includes an elastomeric bushing having first and second ends and an axial bore extending therebetween. A tubular cylindrical sleeve extends through the axial bore and terminates in a first shoulder at one end thereof and in a second shoulder and neck portion at the other end thereof. A first retaining washer is mounted on the sleeve adjacent the first shoulder and the first end of the bushing. A second retaining washer is mounted on the sleeve adjacent the second shoulder and its neck portion of the second end of the bushing. A spacer ring is mounted on the sleeve's neck portion adjacent to the second retaining washer. When assembled, the shoulder portion and the spacer ring member exert axial pressure on the first and second retaining washers which, in turn, serve to compress the bushing in an axial direction to maintain the bushing under a predetermined axial compression. An eye ring coaxially encircles the bushing between its ends to permit attachment of the sleeve and bushing assembly to a shock absorber.
