Abstract
A vehicle wheel (1) allows a communication hole (18a) for a first Helmholtz resonator (auxiliary air chamber members (10a, 10d)) having a lower resonance frequency than that of an air column resonance sound of a tire and a communication hole (18a) for a second Helmholtz resonator (auxiliary air chamber members (10b, 10c)) 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).
Claims2
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 hole for the first Helmholtz resonator and the communication hole for the second Helmholtz resonator are disposed at positions facing each other across a wheel rotation center, and a line that connects the communication hole for the first Helmholtz resonator with the communication hole for the second Helmholtz resonator in 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 another group, are perpendicular to each other.
