Abstract
Contact noise generated between a striker cap mounted on a strut and a jounce bumper connected to a shock tower is reduced by providing an axial projection on the roof of the striker cap. The projection progressively displaces and compresses the elastomeric jounce bumper material and thereby avoids large compressive impulse forces and associated noise generation.
Claims7
A striker cap for a vehicle suspension system, comprising:
- a cup-shaped body having a substantially cylindrical side wall and a roof connected to said side wall, said roof having an aperture formed therethrough and at least one bumper extending outwardly from said roof for limiting initial contact area between said suspension system and said roof wherein said bumper comprises a ridge located adjacent said aperture and wherein said ridge comprises a pair of arches located on opposite sides of said aperture.
A striker cap for engaging a jounce bumper in a vehicle suspension system comprising:
- an annular engagement surface formed on said cap and comprising an axial projection extending from said cap toward said jounce bumper, said projection having a cross-section decreasing in area from said cap toward said jounce bumper and wherein said engagement surface comprises an arched surface portion.
A striker cap assembly for a vehicle suspension system, comprising:
- a strut cylinder mounted in said suspension system and having an end portion;
- a jounce bumper mounted in said suspension system, and fitted on and around said end portion of said strut cylinder;
- and
- a striker cap comprising a cup-shaped body having a substantially cylindrical side wall and a roof connected to said side wall, said roof having an aperture formed therethrough and at least one arched axial projection extending axially outwardly from said roof for limiting initial contact area between said jounce bumper and said roof.
