ABSTRACT:
A jounce bumper is described as being formed of resilient eleastomeric material. The bumper comprises a cylindrical head protruding from a hollow cylindrical body which terminates at an outstanding annular flange. An annular extension of the body extends from the body in spaced relation around the head to form an annular void around the head. The body extension has a free marginal edge which curves inwardly towards the head and terminates in close proximity to the head to prevent particulate matter from entering the void which is sized to have a volume which is correlated to the displacement of the head when a predetermined load is applied against the head. Voids are placed in the head and body to provide the deflection control characteristics desired. A rigid metal sleeve is encased in the extension of the body to prevent radial displacement of the head beyond filling of the void around the head.
