ABSTRACT:
An automotive vehicle suspension shock-absorbing assembly providing a metal-to-metal jounce stop arrangement. The lower extremity of a cylindrical canister, extending downwardly from an upper coil spring seat, defines an upper angular jounce stopper while a striker plate, fixed on the upper end of a shock-absorber unit, is formed with a downwardly off-set annular lower stopper ledge. The arrangement enables maximum jounce travel while limiting compression of the elastomeric jounce bumper, encircling the shock piston rod, to a predetermined axial dimension thereby substantially increasing its service life. Further, the canister shields the bumper during full jounce obviating damage thereto. The canister lower end portion has an inturned shoulder from which an inwardly offset ring depends terminating in an exterior return bent hemmed flange. The return flange upper free edge is axially spaced subjacent the inturned shoulder providing an external annular groove sized to capture an elastomeric dust shield retaining rib.
