Abstract
Official abstract text for this publication.
A wheel resonator for a vehicle may include a resonant plate which has an annular structure that is wound around a rim portion of a wheel while maintaining predetermined tension, has resonant holes formed at predetermined intervals in a circumferential direction, and forms a resonant chamber together with a surface of the rim portion, and sealing plates formed integrally with both end portions of the resonant plate, and tightly attached to and supported on an inner wall surface of the rim portion.
First claim
Opening claim text (preview).
What is claimed is: 1 . A wheel resonator for a vehicle, comprising: a resonant plate which has an annular structure that is wound around a rim portion of a wheel while maintaining predetermined tension, has resonant holes formed at predetermined intervals in a circumferential direction, and forms a resonant chamber together with a surface of the rim portion; and sealing plates formed integrally with both end portions of the resonant plate, and tightly attached to and supported on an inner wall surface of the rim portion. 2 . The wheel resonator of claim 1 , wherein the resonant plate and the sealing plates are made of a plastic material having its own tension. 3 . The wheel resonator of claim 1 , wherein a rigidity reinforcing flange, which protrudes toward the resonant chamber, is formed integrally with an inner circumferential portion of the resonant hole. 4 . The wheel resonator of claim 1 , wherein inner partition walls, which are tightly attached to the surface of the rim portion to divide the resonant chamber into several chambers and reinforce rigidity in a radial direction, are formed integrally with a bottom surface of the resonant plate. 5 . The wheel resonator of claim 1 , wherein the resonant plate and the sealing plates are formed as an annular band piece which has a length smaller than a diameter of the rim portion of the wheel and has both free ends, and the resonant plate and the sealing plates are wound around the rim portion and extended so that the resonant plate has predetermined tension, and then both the free ends are integrated by laser welding or high frequency welding.
