Vehicle suspension strut with quick take-apart upper mount featuring a jounce bumper retainer which can be turned from a locked to an unlocked position and axially removed for jounce bumper service and to allow access to service the strut through the engine compartment so that the expense of removing the strut and spring is eliminated. The design effectively eliminates prior upper spring seat designs and is simple and inexpensive and readily accommodates high service loads.

Suspension strut with quick take-apart upper mount

A vehicle wheel suspension including a strut member provided at its lower end with a wheel spindle and a connection with a lateral lower control arm, further includes mounting apparatus for attaching the upper end of the strut to a stamped sheet metal tower portion of the vehicle superstructure and having provisions for adjustment of either wheel caster or wheel camber via relative movement of the upper end of the strut relative to the tower.

Vehicle strut type suspension with alignment adjustment

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.
