This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be greater than the average thickness (T2) of the rim part. In other words, the relation T1>T2 holds.

The present disclosure provides a method of manufacturing a one-piece wheel having a hollow structure for noise reduction. At least one embodiment of the present disclosure provides a method of manufacturing a one-piece wheel having a hollow structure for noise reduction, the method comprising: fabricating, by using one or both of gravity casting and low-pressure casting, an integral casting in which a disk portion and a wheel rim portion are integrally formed, wherein the rim portion includes an annular protrusion radially protruding from an outer circumferential surface; forming at least one cavity by bending the annular protrusion through flow forming to provide a bending portion, resulting in the cavity using the bending portion and one side of the disk portion; and performing a friction stir welding between the one side of the disk portion and one end of the bending portion.

A method and a plant for the production of a rim for a wheel of a vehicle. At first and by means of an additive manufacturing process, a temporary rim is manufactured, which is provided with a central hub, with a raw ring arranged around the central hub and with a series of spokes, which are radially arranged and connect the raw ring to the central hub; subsequently, the temporary rim is subjected to a flow-forming process, which deforms the raw ring determining an axial lengthening thereof, which transforms the raw ring into a channel having the desired final shape.

Vehicle wheels and methods of making vehicle wheels are provided. The vehicle wheel comprises a generally annular first region, a second region, and a flange region. The first region comprises an outer surface, an inner surface, a first end, and a second end. The second region extends radially inwardly from the first region, and the second region is configured to mount to a vehicle axle. The flange region extends from the first region. The flange region comprises a first flange end adjacent to the first end of the first region, a second flange end, and a curved elongate portion extending intermediate the first flange end and the second flange end. The curved elongate portion comprises a first thickness no greater than 0.3 inches and a second thickness greater than 0.3 inches.

A wheel rim having a central axis and comprising a central hub configured to be fixed to a suspension of a vehicle; a peripheral ring, which is arranged around the hub with a predetermined radial distance from the hub itself and is configured to receive a tire of the vehicle on a radially outermost surface thereof; a plurality of spokes equally spaced angularly from one another around the axis and connecting the peripheral ring to the hub; and at least one projection protruding in a cantilever fashion towards the hub, starting from a radially innermost surface of the peripheral ring, opposite to the radially outermost surface, and defining an airfoil configured to generate, in use, during the forward travel of the vehicle, a channelling of the air towards the outside of the wheel rim.

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 universal temporary wheel is provided that has a universal aperture pattern that is adapted to mate with different configurations of lug bolt patterns to enable the wheel to be used with various wheel hub configurations having various lug bolt patterns. The universal temporary wheel can be installed while a damaged wheel is being repaired to allow an automobile or other vehicle to be moved. Because the universal temporary wheel has a universal aperture pattern, the wheel can be used with a variety of wheel hub configurations and lug bolt patterns, thereby eliminating the need to stock a variety of temporary wheels having various aperture patterns.
