Abstract:

An integrated shock absorber assembly which integrates a shock absorber with a jounce stop and a coil spring. At an upper end of the cylinder of the shock absorber is a bumper cap in the form a robust annular washer. A jounce stop includes a bump cushion, a cushion cup having dimpling to provide a cup abutment, and a jounce stop bracket for attachment to the motor vehicle frame. As maximum jounce is approached, the bumper cap resiliently compresses the bump cushion, and in a maximum jounce, the bumper cap strikes, metal-to-metal, the cup abutment.
