ABSTRACT:
A jounce bumper assembly for cushioning the impact between two components of an automotive suspension system is provided. The jounce bumper assembly includes a mounting plate with at least one, but preferably two, substantially tubular proturbances protruding from a face thereof. A bumper is molded from a microcellular polymeric material around the mounting plate such that the ends of the proturbances extend out from the bumper. The bumper is disposed within a mounting cup having a recess sized and shaped to receive the bumper. The recess has holes passing therethrough corresponding to the proturbances such that the ends of the proturbances pass through the holes. The ends of the proturbances passing through the holes are deformed radially outwardly such that the bumper is fixed within the recess of the mounting cup. A method of manufacturing such a jounce bumper assembly is also provided.
