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.
