Abstract

A vehicle wheel includes: a pair of rail members configured as separate members from the rim and fixed to an outer circumferential surface of a well portion of a rim; and a sub air chamber member serving as a Helmholtz resonator and disposed between and supported by the rail members. A distance between the pair of rail members in a wheel width direction becomes gradually narrower from the outer circumferential surface of the well portion toward outside in a wheel radial direction that is orthogonal to the wheel width direction. Further, the pair of rail members have inner surfaces located to face the outer circumferential surface in the wheel radial direction, and the sub air chamber member has a contour to conform with the inner surfaces of the pair of rail members.

Claims

1. A vehicle wheel comprising:

a pair of rail members fixed to an outer circumferential surface of a well portion of a rim of a wheel, the pair of rail members being separate members from the rim; and

a sub air chamber member serving as a Helmholtz resonator, the sub air chamber member being disposed between the rail members and supported by the rail members,

wherein a distance between the pair of rail members in a wheel width direction becomes gradually narrower from the outer circumferential surface of the well portion toward outside in a wheel radial direction that is orthogonal to the wheel width direction, and

wherein the pair of rail members have inner surfaces located to face the outer circumferential surface in the wheel radial direction, and the sub air chamber member has a contour to conform with the inner surfaces of the pair of rail members.

2. The vehicle wheel according to claim 1, wherein a width of the sub air chamber member becomes gradually wider toward the outer circumferential surface of the well portion to match the distance between the pair of rail members.

3. The vehicle wheel according to claim 1, wherein the pair of rail members curve outward in the wheel radial direction as viewed in a section taken on a plane orthogonal to a wheel circumferential direction that is orthogonal to the wheel width direction and the wheel radial direction.

4. The vehicle wheel according to claim 3, wherein the sub air chamber member has a bulged portion jutting out farther toward outside in the wheel radial direction beyond distal ends of the pair of rail members.

5. The vehicle wheel according to claim 1, wherein each of the rail members comprises a base portion disposed along the outer circumferential surface of the well portion, and a support portion integral with the base portion and configured to extend from an inner end portion of the base portion in the wheel width direction such that the more it extends inward in the wheel width direction, the farther it is located from the outer circumferential surface in the wheel radial direction.

6. A method of manufacturing a vehicle wheel according to claim 1, the method comprising:

a first step of disposing the sub air chamber member on the outer circumferential surface of the well portion at a predetermined position, and

a second step of fixing the pair of rail members to the outer circumferential surface of the well portion after the first step.
