ABSTRACT:
The drawings illustrate a MacPherson strut-type concentric shock absorber and coil spring. A single elastomeric ring is preloaded between upper and lower retainer members, and suitable bearing means are mounted between the bottom portion of the elastomeric ring and a spring retainer flange for the upper end of the coil spring. The piston rod is secured within the center portion of the elastomeric ring. In this arrangement, the preloaded outer portion of the elastomeric ring is subjected to compression forces during jounce and rebound conditions, and the preloaded center portion of the ring is subjected to shear forces during such jounce and rebound conditions, thereby providing predetermined different stiffness characteristics for the shock absorber and the coil spring.
