A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim bed bounded on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt circle, as well as a rim center connecting the rim bed and the hub to one another, the rim center being designed with a plurality of spokes spaced apart in the circumferential direction with respect to the longitudinal center axis of the automobile rim. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material, wherein the automobile rim has, at least in some areas, a low wall thickness not exceeding 15 mm.

A vehicle wheel for commercial vehicles, having a fastening device for an aerodynamic wheel disc cover. In order to enable secure and easy fastening of the disc cover, the fastening device comprises several fastening holes arranged in the hub connection flange, with at least one fastening hole consisting of a through hole having a smaller diameter on the front side of the wheel than on a rear side of the hub connection flange and forming an abutment for a detachable retaining means acting by form fit, and/or wherein at least one fastening hole consists of a through hole provided with an internal thread for screwing in a fastening screw as a retaining means, and/or that the centre hole has an inner circle edge comprising a constriction which forms an abutment for a cover side arranged retaining means acting by form fit.

A bicycle disc or spider wheel including: a hub; a rim having a radially outer tire-coupling region, a first sidewall, a second sidewall; an axis of rotation; and a median plane. A pair of pretensioned disc or spider wheel-type structural elements are integral with the hub and with the rim. The first sidewall extends on a first side of the wheel, with respect to the median plane, on which a component of a motion transmission system or, when there is none, a disc of a disc brake is provided at the hub, and the second sidewall extends on the opposite side, with respect to the median plane. The first sidewall of the rim has a minimum distance from the median plane that is smaller than that of the second sidewall of the rim.

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 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.

A wheel disc adapted for use in a fabricated vehicle wheel comprising a steel wheel disc defining an axis and including a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

A vehicle wheel includes a rim having an inner peripheral surface, and a center disc. The center disc includes a disc portion, and an arm plate portion extending radially outward from the disc portion. The arm plate portion includes an outer boundary defined by a plurality of arc outer peripheral surfaces and a plurality of concave boundary surfaces. The plurality of arc outer peripheral surfaces have a radius equal to a radius of the inner peripheral surface of the rim. The plurality of arc outer peripheral surfaces are joined to the inner peripheral surface of the rim at a weld attachment interface to produce a plurality of holes defined by the plurality of concave boundary surfaces and the inner peripheral surface of the rim.

An apparatus for a single-track motor vehicle includes a first wheel disc and a second wheel disc. The first wheel disc and the second wheel disc are configured on the wheel rim so as to be mutually spaced apart in a transverse direction parallel to the rotation axis (A) of the disc wheel, and extend from the wheel rim in the direction of the wheel hub. The wheel discs converge in the direction of the wheel hub and are connected to one another in such a manner that at least one cavity between the wheel discs and the wheel rim is formed. At least one cutout toward the at least one cavity is formed in a rim well of the wheel rim.

Various embodiments of an airless tire are disclosed. In some embodiments, the tire can include a hub and a tread. A cushioning unit can be positioned between the hub and the tread. A support can be positioned between, and can provide structural support to, the cushioning unit and the tread.

A vehicle wheel includes a wheel substrate made of metal and a colored coating layer located on a surface of the wheel substrate. An outer side surface of the wheel includes a first region, a second region, and a groove located between the first and second regions. The colored coating layer covering the wheel substrate is located over the groove. A color of the surface of the wheel substrate is visible at least in the first or second region.
