A bicycle rim has rim a pair of rim flanges that defines a tire channel. A rim strip extends across the tire channel. The rim strip includes a pair of flange bumpers configured to cover the rim flanges. The flange bumpers each define a flange channel in which one of the rim flanges is received. A pair of safety humps define corresponding tire seating sections where a tire is seated when inflated. The rim strip further includes a drop seal that seals with the beads of the tire to facilitate seating of the tire during inflation.

A vehicle wheel includes: a rim including a well portion and a guide member, and a sub-air chamber member serving as a Helmholtz resonator. The well portion has an outer circumferential surface extending in a wheel circumferential direction of the vehicle wheel. The guide member has a rail-like shape and extends in the wheel circumferential direction along the outer circumferential surface. The guide member engages with the sub-air chamber member to guide the sub-air chamber member in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim.

A disc portion and a rim portion of a tire wheel are integrally formed simultaneously, with a resonance pipe formed between the disc and rim portions, by inserting a molten metal into a space formed by a mold combined with the resonance pipe by core pins.

Disclosed is an aluminum wheel for a vehicle, in which a resonance tube is coupled to a rim of the wheel, wherein a first surface of the resonance tube is fitted into a well groove formed in a well of the rim, and a second surface of the resonance tube comes into contact with the rim by a pressure member including a steel wire and a fixing member.

A wheel width direction (Y) cross-section of a well portion (11A) includes a hump portion (H1) and a hump portion (H2) that protrude to the outside (Z1) in a wheel radial direction (Z), and a curved surface (11s) that connects hump portion (H1) and hump portion (H2) and is sunken to the inside (Z2) in the wheel radial direction (Z). The curved surface (11s) is formed as a series of circular arcs (11e, 11f, 11g) that have centers of curvature (O1, O2, O3) that are further to the outside (Z1) in the wheel radial direction (Z) than the curved surface (11s).

In a vehicle wheel of the present invention, a sub-air chamber member functioning as a Helmholtz resonator includes a main body section forming a sub-air chamber in a space surrounded by a bottom plate adjoined to the outer circumferential surface of a well section and extending in a wheel width direction, an upper plate opposed to the bottom plate at a predetermined interval on an outer side in a wheel radial direction of the bottom plate, and a pair of side plates standing outward in the wheel radial direction from both ends in the wheel width direction of the bottom plate, and a pair of edge sections which extend outward in the wheel width direction from respective joining sections of the bottom plate and the pair of side plates, and which are locked to the well section.

Provided is a vehicle wheel to have a Helmholtz resonator mounted to a rim with an old structure, without circumferential grooves cut in the rim so as to have the Helmholtz resonator mounted therein. A vehicle wheel (1) includes a rim (11) formed by joining an inner rim (14a) and an outer rim (14b), and a sub air-chamber member (10) as a Helmholtz resonator, wherein the sub air-chamber member (10) is mounted to the rim (11) via a support member (20) held between the inner rim (14a) and the outer rim (14b).

A vehicle wheel includes a pair of vertical walls that extend vertically up from an outer circumferential surface of a well portion and extend in a wheel circumferential direction and a Helmholtz resonator that is disposed between the pair of vertical walls and bonded to side surfaces of the pair of vertical walls with an adhesive, in which the Helmholtz resonator is not bonded to the outer circumferential surface of the well portion.

A composite wheel for use at normal tire pressures as well as at reduced tire pressures may include a spoke section with a mating surface, a barrel section in contact with the spoke section at said mating surface, and a bead hump with tire lock geometry on at least the spoke section. The barrel section may further include a bead hump with the tire lock geometry.
