Abstract
A wheel structure for vehicles, capable of reducing a columnar resonance sound occurring in a wheel during a travel of a vehicle. A cross-sectional shape of a closed space defined by a wheel and a tire is varied in the circumferential direction so that a columnar resonance frequency in the closed space varies with a rotation of a wheel unit.
Claims2
A wheel structure comprising:
- a wheel;
- and
- a tire fitted on an outer circumference of the wheel;
- two projections provided on a part of a closed space defined by the wheel and the tire and varying a cross-sectional shape of a closed space defined by the wheel and the tire in the circumferential direction thereof,
- wherein only the two projections are provided in the circumferential direction so that a columnar resonance frequency in the closed space varies with a rotation of the wheel structure by varying the cross-sectional shape of the closed space in the circumferential direction thereof, and
- wherein the projections are provided on an inner circumferential surface of a tread of the tire.
