Jounce bumper

摘要

A jounce bumper is used in a suspension system of a vehicle. The jounce bumper comprises an outer member comprising a base portion and a sidewall extending from said base portion. The sidewall of the outer member is flexible relative to the base portion. The base portion and the sidewall define a cavity such that the outer member has a cup-shaped configuration. A bumper is at least partially seated within the cavity of the outer member. The bumper is compressible into the cavity of the outer member such that the bumper expands against the sidewall of the outer member, which forces the sidewall of the outer member to flex and expand radially outward. An isolation layer is disposed on the base of the outer member outside of the cavity and separates the outer member from either the strut assembly or the frame member.

主权项

1. A jounce bumper assembly for a suspension system of a vehicle with the vehicle including a frame member and the suspension system including a strut assembly moveable relative to the frame member, said jounce bumper assembly comprising:
an outer member capable of being disposed between the frame member and the strut assembly with said outer member having a base portion and a sidewall extending from said base portion with said sidewall flexible relative to said base portion and with said base portion and said sidewall defining a cavity such that said outer member has a cup-shaped configuration; a bumper at least partially seated within said cavity of said outer member with said bumper compressible into said cavity of said outer member such that said bumper expands radially against said sidewall of said outer member thereby forcing said sidewall to flex and expand radially outward; and an isolation layer disposed on said base portion of said outer member outside of said cavity for separating said outer member and either the strut assembly or the frame member such that said outer member is isolated from either the strut assembly or the frame member as said sidewall of said outer member expands radially outward thereby minimizing noise produced as said bumper is compressed and said sidewall expands radially outward.
