Abstract:
In combination with a motor vehicle having a vehicular chassis with a conical strut tower formed therein and a wheel suspension mechanism including a collapsible strut member comprising a central body with upper chassis coupling and lower wheel assembly coupling ends and with a load bearing coil spring arranged coaxially about said collapsible strut member for creating a responsive load bearing force between said chassis and said wheel suspension mechanism; a wheel alignment adjustment assembly interposed between said chassis and said wheel suspension mechanism and comprising an upper strut mount assembly for receiving and adjustably positionably coupling said upper chassis coupling end within the conical strut tower of the vehicle chassis with said upper strut mount assembly comprising:(a) an offset upper strut mount body member comprising upper and lower offset portions of generally conical configuration, the portions being spaced apart by a separator plate having a bore extending therethrough disposed centrally of said lower portion and eccentrically of said upper portion; (b) said upper body portion having a central axis with a conical outer wall surface arranged to be received within and mate with said chassis tower and having an open top chamber formed therein; (c) a resilient pad having a scalloped outer surface secured to said conical outer wall and designed to mate with said chassis tower; (d) said lower body portion having an axis parallel to and offset from the axis of said upper chamber and having a conical outer wall, an open bottom chamber formed in said lower body portion and with said lower body portion having a counter-bore defining an annular coil spring retaining skirt extending axially downwardly from said lower body portion; (e) a cup washer retainer arranged to be disposed along the top surface of said conical strut tower, said cup washer having an eccentric bore formed therein coaxially with the eccentric bore of the upper portion, said cup washer retainer further having an outer peripheral edge with a closed annular torroidal ring formed of resilient material; (f) said upper chassis coupling end having a distal tip end, with said distal end being arranged to extend through the bore of said separator wall and said cup washer and to be fastened directly to said separator wall and to said cup washer retainer; (g) the arrangement being such that at least one of camber and caster adjustment is accomplished through selected adjustable rotatable positioning of said upper strut mount body member within said conical strut tower along an axis spaced from the axis of the upper body portion and at a desired angular position relative to the axis of said conical strut tower for achieving positionable adjustment of the upper end of said collapsible strut member relative to said vehicular chassis.
