Abstract

This vehicle wheel includes: a first vertical wall surface defined by one rising part of a rim that forms a well part and a second vertical wall surface defined by another rising part are provided; an auxiliary air chamber member has a main body part with an auxiliary air chamber on the inside and has edge parts extending from each of both sides of the main body part in the wheel width direction; each of the edge parts of the auxiliary air chamber member fits into a groove formed in each of the first vertical wall surface and second vertical wall surface, and the auxiliary air chamber member is thereby attached atop the outer circumferential surface of the well part.

First claim

The invention claimed is:

1. A vehicle wheel in which a plurality of sub air chamber members, configured as Helmholtz resonators, are attached to an outer circumferential surface of a well portion, said vehicle wheel comprising:
a first substantially vertical wall surface restricted by a first one of a pair of standing-up portions of a rim forming the well portion; and
a second substantially vertical wall surface restricted by a second one of the standing-up portions of the rim forming the well portion,
wherein each sub air chamber member includes:
a main body portion having a sub air chamber formed therein which is defined by a space enclosed by a top plate, a bottom plate and a pair of side plates, the pair of side plates extending upwardly from opposite sides of the bottom plate, in a wheel width direction, and extending outward from the bottom plate substantially in a wheel radial direction; and
fringe portions extending from both side plates, respectively, in the wheel width direction, of the main body portion,
and wherein the fringe portions of the sub air chamber member are respectively fitted into groove portions formed respectively on the first vertical wall surface and the second vertical wall surface, so that the sub air chamber member is attached to the outer circumferential surface of the well portion, and
the pair of side plates are formed to extend along the first vertical wall surface and the second vertical wall surface, respectively.

2. The vehicle wheel according to claim 1 , wherein the main body portion of each sub air chamber member includes a recessed portion defined in a partial region on an outer side of the main body portion in the wheel radial direction, the recessed portion configured to temporarily receive a bead of a tire therein when the tire is attached to the wheel.

3. The vehicle wheel according to claim 1 , wherein a cross-sectional shape of the side plates and the bottom plate substantially conform to a cross-sectional shape of the well portion which supportively contacts the side plates and the bottom plate.

4. The vehicle wheel according to claim 2 , wherein a cross-sectional shape of the side plates and the bottom plate substantially conform to a cross-sectional shape of the well portion which supportively contacts the side plates and the bottom plate.
