DEVICE FOR ATTENUATING CAVITY NOISE IN A TIRE AND WHEEL

摘要

A device for attenuating noise generated in a rolling tire and wheel assembly includes strips arranged as a circumferential ring (40) in the tire/whell cavity. The strips are spaced circumferentially to provide a profile of ridges and gaps in the ring. The rings may (40) be placed on the interior surface of the tire or the wheel or both. Preferably, two rings are formed, and the gaps of ths rings are in staggered relationship about the circumferential direction.
