Abstract
Official abstract text for this publication.
A vehicle wheel ( 1 ) allows a communication hole ( 18 a ) for a first Helmholtz resonator (auxiliary air chamber members ( 10 a, 10 d )) having a lower resonance frequency than that of an air column resonance sound of a tire and a communication hole ( 18 a ) for a second Helmholtz resonator (auxiliary air chamber members ( 10 b, 10 c )) having a higher resonance frequency than that of the air column resonance sound of the tire to be disposed at positions facing each other across a wheel rotation center (Ax).
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle wheel provided with Helmholtz resonators each having an auxiliary air chamber member communicated with a tire air chamber through a communication hole, the vehicle wheel comprising two groups of Helmholtz resonators, each group including: a first Helmholtz resonator that is set to have sound deadening characteristics for a sound having a lower resonance frequency than a resonance frequency of an air column resonance sound in the tire air chamber; and a second Helmholtz resonator that is set to have sound deadening characteristics for a sound having a higher resonance frequency than the resonance frequency of the air column resonance sound, wherein the communication holes for the first and the second Helmholtz resonators included in one group, and the communication holes for the first and second Helmholtz resonators included in another group, are disposed at positions facing each other across a wheel rotation center, respectively, and a line that connects the communication hole for the first Helmholtz resonator with the communication hole for the second Helmholtz resonator in the one group, and a line that connects the communication hole for the first Helmholtz resonator with the communication hole for the second Helmholtz resonator in the other group, are perpendicular to each other. 2. The vehicle wheel according to claim 1 , wherein when the resonance frequency of the air column resonance sound in the tire air chamber is expressed as f MC , a resonance frequency of the first Helmholtz resonator is set to f MC −α [Hz], where α is a positive number of 1 to 10, and a resonance frequency of the second Helmholtz resonator is set to f MC +α [Hz].
