ABSTRACT:
An automotive suspension strut upper mounting arrangement providing a one-piece elastomeric block isolator adapted for enclosure in a two-piece housing comprising upper and lower closure members. The isolator, which has a central generally tubular shape, is molded with an upper jounce collar and a lower rebound collar. A continuous internal radially extending tuning groove is formed in the jounce and rebound collars. By varying the axial dimension of the grooves the mount axial spring rate may be fine tuned to smoothly receive axially imposed suspension loads. Additionally, the isolator body outer surface may formed with a plurality of recesses defining predetermined voids providing selective tuning of laterally imposed suspension loads.
