TYRE CAVITY NOISE ABSORBER

摘要

A tyre cavity noise absorber has a body of sound absorbing material (1) and a support (2). The absorber is arranged such that, when installed in a tyre cavity and the tyre is stationary, the support supports the body of sound absorbing material in a position spaced from the inside circumferential wall of the tyre. The support may be flexible and allow the body of sound absorbing material to expand towards and contact the inside of the tyre when the tyre rotates.
