JOUNCE BUMPER NOSE RETAINING FEATURE FOR A SHOCK ABSORBER

摘要

A shock absorber includes an elastomeric jounce bumper which engages a jounce bumper cap during relatively large compression movements of the shock absorber. The jounce bumper cap includes a jounce bumper nose retaining feature which engages the nose of the jounce bumper during the compression movements. The jounce bumper nose retaining feature restricts sliding movement of the elastomeric jounce bumper with respect to the jounce bumper cap to eliminate noises associated with the relative movement.

主权项

1. A shock absorber comprising:
a pressure tube defining a fluid chamber; a piston assembly slideably disposed within said fluid chamber, said piston assembly dividing said fluid chamber into an upper working chamber and a lower working chamber; a piston rod attached to said piston assembly, said piston rod extending through one of said upper and lower working chambers; a jounce bumper cap disposed at an end of said pressure tube, said piston rod extending through a through bore defined by said jounce bumper cap; a jounce bumper nose retaining feature disposed around said through bore defined by said jounce bumper cap; an elastomeric jounce bumper disposed around said piston rod, said elastomeric jounce member having a nose configured to engage said jounce bumper nose retaining feature; wherein engagement between said nose of said elastomeric jounce bumper and said jounce bumper nose retaining feature during a compression movement of said shock absorber restricts radial movement of said nose with respect to said jounce bumper nose retaining feature.
