A rim portion of a vehicle wheel has an outer flange portion. In a region of the outer flange portion, a space portion between spoke portions is disposed on a radial-direction inner side, a first inclined surface and a second inclined surface are provided. The first inclined surface is provided on an axial-direction outer side of an outer flange outer circumferential portion. The second inclined surface is on an axial-direction outer side of an outer flange inner circumferential portion. The first inclined surface is formed to incline from the axial-direction outer side toward an axial-direction inner side as the first inclined surface extends from a radial-direction outer side end toward the radial-direction inner side. The second inclined surface is a surface formed to incline from the axial-direction inner side toward the axial-direction outer side as the second inclined surface extends from the radial-direction outer side toward the radial-direction inner side.

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 engages with the sub-air chamber member to guide the sub-air chamber member on the outer circumferential surface in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim.

A wheel structure for a vehicle includes: a rim, and a resonator including a plurality of resonance tubes attached along an outer peripheral surface of the rim. The plurality of resonance tubes are spaced apart from each other and connected along the outer peripheral surface of the rim by a plurality of strips, and an end of each of the strips is coupled to a corresponding end of each of the resonance tubes.

A bicycle rim is made with a plurality of layered, each of which is formed of structural fibres incorporated in a polymeric material. The rim has a radially outer peripheral channel with an upper bridge extending between the wings for holding a tyre. The peripheral channel comprises an inner layered structure, extending between wings and at least one wrapping layered structure, wound on the inner layered structure at least at the end of the wings, the inner layered structure and the wrapping layered structure being included in the plurality of layered structures.

Disclosed are an explosion-proof tire hub, including a hub body and an explosion-proof convex retainer. The hub body includes bent portions configured to mount a vacuum tire, the hub body is provided with a central axis, the explosion-proof convex retainer is fixed on the hub body, the distance between an upper end of the explosion-proof convex retainer and the central axis is L1, the distance between an upper end of the bent portion and the central axis is L2, and L1 is greater than L2. In case of burst or instantaneous pressure loss, because the distance L1 between the upper end of the explosion-proof convex retainer and the central axis is greater than the distance L2 between the upper end of the bent portion and the central axis, the explosion-proof convex retainer reduces the distance between the whole hub and the ground during tire burst and improves safety performance.

A device configured for coupling a resonator to a vehicle wheel, may include an annular first strap assembled with an external circumferential surface of the wheel rim and fixing positions of resonators disposed on the external circumferential surface of the wheel rim; and an annular second strap surrounding second flanges formed at second edge portions of the resonators based on an axial direction of the wheel rim and pressurizing the second flange toward the external circumferential surface of the wheel rim after first flanges, which are formed on second edge portions of the resonators based on an axial direction of the wheel rim, are inserted between the first strap and the external circumferential surface of the wheel rim

A bicycle rim assembly includes a rim defining a central plane and comprising annular inner and outer walls. The outer wall includes first and second bead seats separated by a center well. First and second annular projections are spaced laterally from each other relative to the central plane and extend substantially radially outwardly from the outer wall. Each of the annular projections includes a radially outer face and a laterally inner face. Right and left covers are spaced from each other and are preferably coupled to the rim to cover at least a portion of the laterally inner face and the radially outer face of the first and second annular projections, respectively, and also the first and second bead seats, respectively. One or both of the right and left covers can be fiber reinforced. First and second pieces of tape can be overlapped and used to secure the covers to the rim.

A method for producing a drop centre rim and to a drop centre rim for vehicle wheels of commercial vehicles. The rim has a plurality of zones, which form an inner rim flange and an outer rim flange, an inner steep-tapered bead seat and an outer steep-tapered bead seat and a rim drop centre with a drop centre base, an inner drop centre flank and an outer drop centre flank between the steep-tapered bead seats, wherein one of the zones is provided as a disc attachment region for a wheel disc, and the drop centre rim has at least one partial zone with a reduced wall thickness relative to the other zones. It is envisaged that at least one of the steep-tapered bead seats, preferably both steep-tapered bead seats, has/have a section with a wall thickness reduction of more than 20% relative to the wall thickness in the zone provided as the disc attachment region, wherein the wall thickness reduction is produced during one of the profiling steps.

A resonator wheel is disclosed. In accordance with one aspect of the present invention, the resonator wheel includes a wheel rim; a first annular wall protruding from an outer circumferential surface of the wheel rim along a circumference of the wheel rim, the first annular wall including a tube mounting groove formed on one side surface of the first annular wall; a second annular wall protruding from the outer circumferential surface of the wheel rim along the circumference of the wheel rim and spaced apart from the first annular wall; a plurality of resonance tubes disposed on the outer circumferential surface of the wheel rim between the first annular wall and the second annular wall, each of the resonance tubes including: a tube body including a resonance chamber and a communication hole extending from the resonance chamber; a first flange protruding from one side of the tube body and having one end inserted into the tube mounting groove; and a second flange protruding from a an opposite side of the tube body and having one end disposed adjacent to the second annular wall; and a fastening member surrounding one radially outer surface of the second flange between the tube body and the second annular wall along the circumference of the wheel rim, the fastening member pressing the second flange in a radially inward direction of the wheel rim.

A wheel for a vehicle is provided. The wheel has a rim configured for mounting a tire thereto. The wheel also has a rotary drive member that is integrally connected to the rim. The drive member is configured to be operatively connected to a motor of the vehicle.
