The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

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.

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.

Hubcap (1) for a wheel (2) with a floating tyre seat, the said wheel (2) having a rim comprising a tyre seat (253) extended axially outwards by a flange (254), the tyre seats (253) being radially floating, the said hubcap comprising a central edge (11) and an exterior periphery (12), in which the said central edge (11) comprises fixing elements for attaching to the rigid part of the wheel and in which the said central edge (11) is connected to the said exterior periphery (12) by an intermediate sector that is deformable so that the exterior periphery (12) can be moved at least radially inwards with respect to the central edge (11).

A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.

A vehicle wheel rim is printed with a metal alloy by a three-dimensional printing method. The rim includes a substantially circular rolling strip defined by a front edge and a rear edge. The rolling strip includes a central rim base, a front part including fittings for a front tire support, located between the rim base and the front edge, and a rear part including fittings for a rear tire support, located between the rim base and the rear edge. The rim is designed to be mounted on a vehicle such that the front edge is located on an outer side of the vehicle and the rear edge is located on an inner side of the vehicle. The rolling strip includes a plurality of cavities in the thickness thereof and in a radial section.

A wheel assembly includes a rim having a primary tire bead retention ridge; a plurality of secondary bead retention members; and a plurality of sealing members. The plurality of secondary bead retention members are removably coupleable to receptacles of the rim such that a portion of each secondary bead retention member extends into a pressurized portion of the wheel, is positioned behind a tire bead seat, and extends radially beyond the primary tire bead retention ridge.

A rim assembly for a bicycle wheel includes a rim, a first protruding tire retaining feature attached to a first surface of the rim, and a second protruding tire retaining feature attached to a second surface of the rim. The first surface is a surface of a first tire retaining wall of a radially outer tire engaging portion of the rim, and the second surface is a surface of a second tire retaining wall of the radially outer tire engaging portion. The second surface faces the first surface. The first protruding tire retaining feature and the second protruding tire retaining feature are made of a first material, and the first tire retaining wall and the second tire retaining wall are made of a second material. The second material is different than the first material.

Bicycle rims that allow tires to be more easily mounted in a tubeless configuration are disclosed. More specifically, a bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels.

The rolling assembly has a rotation axis and comprises a rim having two rim seats that is axially outwardly extended by rim flanges, one adapter and a tire having two beads. The adapter provides the connection between one of the beads and the rim and comprises an axially inner end that is adapted to be mounted on one of the rim seats, an axially outer end that is adapted to receive one of the beads and an adapter body connecting the axially inner end and the axially outer end as to form a single piece. The two rim seats of the rim have different diameters with a gap D. The adapter is mounted onto the rim seat having smaller diameter. The rim seat of the rim has a smaller diameter positions on a side intended to be inside when the rolling assembly being mounted onto a vehicle.
