A composite wheel assembly and method of fabricating the same is provided. The wheel assembly includes a composite wheel rim, a wheel center, and a plurality of attachment fasteners for attaching the wheel center to the wheel rim. The wheel rim includes a plurality of attachment inserts that are configured to selectively engage with respective attachment fasteners. Each attachment insert is encapsulated by a plurality of composite layers of the wheel rim or is otherwise secured to the wheel rim. The attachment inserts extend from and/or are positioned within a drop well region of the wheel rim. The method of fabricating the wheel assembly includes forming first and second preforms and positioning the same onto a mold assembly. The method further includes positioning the attachment inserts between the first and second preforms such that the attachment inserts are secured therebetween.

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 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 wheel assembly includes a plurality of discreet, axially extending curved friction plates for engaging a first side of a spoke structure of a tire assembly, a first annular rim piece for engaging a rotatable axle, and a second annular rim piece for engaging the first rim piece. The first rim piece and the second rim piece each have axially extending lugs for engaging opposite ends of the friction plates.

An omni-wheel according to the present invention has a continuous axle and roller design enabling robust durability and ease of manufacturing. The omni-wheel hub is designed to be injection moldable in two halves which constrain the continuous axle or be 3D printed as one piece with integral rollers and continuous axle which controllably deform to reduce vibration and under sudden physical shock, deform to protect structural integrity.

A two-piece rim and tire assembly. The tire is held to the rim by fasteners extending through flanges integral with the tire main body and then into the rim. Further, the outer edges of the rim clinchably mount the tire main body thereto. A flexible overhanging portion extends outwardly of the tire main body minimizing dirt and mud accumulation on the tire and rim. A bearing is held within the rim by a ring.
