A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

Methods for fabricating composite wheel assemblies are described, as well as the composite wheel assemblies being fabricated. The composite wheel assemblies may include multiple formed components that are joined together at one or multiple locations within the wheel assemblies, or may be fabricated as a castable wheel. The composite wheel assemblies may be fabricated from reinforced plastic and/or a metal.

A two-part gate wheel is disclosed. The gate wheel includes two hub portions, each of which extends through over 180°, and which has a slot which passes from the periphery through to the centre. In use, each hub portion can be introduced from opposed sides of a gate, and coupled together to form a wheel. In this way the wheel can be retro-fitted onto a gate.

A disk wheel for a motor vehicle, in particular a single-track motor vehicle, includes: a wheel hub for mounting the disk wheel on the motor vehicle, which wheel hub is concentric to an axis of rotation of the disk wheel; a wheel rim, which is likewise concentric thereto; and a first and a second wheel disk. The first wheel disk and the second wheel disk each extend from the wheel rim toward the wheel hub, are mutually spaced on the wheel hub in a transverse direction which is parallel to the axis of rotation of the disk wheel, and run toward each other as they approach the wheel hub. The disk wheel also has at least two reinforcement ribs, which extend from the first wheel disk to the second wheel disk and interconnect the first wheel disk and the second wheel disk. The reinforcement ribs are distributed evenly around the axis of rotation of the disk wheel.

A composite wheel assembly and method of construction thereof is provided. The composite wheel assembly includes a lightweight annular aluminum barrel having an inner surface and an outer surface configured to support a tire thereon. A lightweight metal central hub assembly is fixed to the barrel. The metal central hub assembly includes a central hub portion and plurality of support spokes extending outwardly from the central hub portion to free ends, wherein the free ends are fixed to the inner surface of the aluminum barrel. A wheel cladding contrasting in at least one of material type, color, texture and surface finish to an outwardly facing surface the central hub assembly is fixed to the outwardly facing surface of the central hub assembly.

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.

Provided is a wheel (6a) in which a disk (62) includes a first rib (62a) extending in a radial direction, and protruding out on one side in a direction of a central axis a1. A hub (61) of the wheel (6a) includes a first blade portion (61d1) extending in the radial direction. At least one of a pair of side surfaces of the first rib (62a) is inclined relative to a plane including the central axis a1 of the disk (62), and the first blade portion (61d1) is fixed to the inclined side surface on one side of the central axis a1.

A commercial vehicle wheel including a rim configured to hold a tire and a wheel disc attached to the rim with an attachment region for removable attachment to a wheel carrier. The wheel disc is formed from at least two parts, which are joined together. At least one of the parts consists of a multiphase steel alloy or a heat-treatable steel alloy.

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A bicycle wheel includes a first panel member including a first rim portion for mounting a tire, a first hub mounting end connected to a hub, a first spoke portion for connecting the first rim portion and the first hub mounting end, a second panel member having a second rim portion for mounting the tire, a second hub mounting end connected to the hub, and a second spoke portion for connecting the second rim portion and the second hub mounting end, wherein the bicycle wheel is formed by joining the first panel member and the second panel member together such that the first panel member and the second panel member are symmetrical to each other about a line passing through the hub and the rim.
