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.

Abstract: An automotive suspension strut upper mounting arrangement providing increased stroke length and enhanced tunability by virtue of the major working area of the mount being located above the tower attachment surface. The mounting assembly comprises an outer housing defined by an upper closure formed with a flanged brim and a lower closure formed with a terminal flange. The housing encloses a composite mount comprising an elastomeric isolator ring surrounding an inner metal cup with the cup upstanding side wall embedded in the ring. The ring has an upper end face which abuts an upper closure internal shoulder and a lower tubular extension sized for press-fit capture in a lower closure annular U-shaped channel. Upon the upper closure flanged brim and the lower closure terminal flange being secured in flatwise contact an axial pre-load is applied to the elastomeric ring.

Abstract: An automotive suspension strut upper mounting assembly providing increased stroke length and enhanced spring rate tunability with the major working area of the mount being located above the body panel attachment surface. The mount comprises a housing including upper and lower closures readily assembled to enclose a composite isolator mount comprising an inner metal cup bonded to an outer elastomeric ring. The composite ring has a concentric sleeve embedded therein defining inner and outer body portions providing an increased spring rate for stiffening lateral vehicle motion caused by handling maneuvers. The inner and outer body portions are each formed with a pair of diametrically opposed fore and aft voids selectively reducing the spring rate thereby softening longitudinally imposed impact loads.

Abstract: An improved suspension strut isolator mount provides a compact resilient isolator assembly configured to facilitate mold bonding of an elastomeric member between a functional member of the strut and an auxiliary sleeve member and press fit insertion of the assembly into a relatively large strut mounting member.
