A method for producing a motor car rim made of aluminum or an aluminum alloy for a wheel of a motor vehicle. The motor car rim has a rim well delimited on opposite sides by an outer flange and an inner flange, a hub with a center recess and a pitch circle diameter, as well as a rim center connecting the rim well and the hub to one another and engaging the rim well off-center in the longitudinal section. The rim center is formed with several spokes spaced apart from one another in the circumferential direction as relates to a center longitudinal axis of the motor car rim.

A method for producing a motor vehicle rim made of aluminum or an aluminum alloy for a motor vehicle wheel. The motor vehicle rim has a rim base delimited on opposite sides by an outer horn and an inner horn, a hub with a central recess and a hole circle and a rim center connecting the rim base and the hub to one another and acting eccentrically on the rim base in longitudinal section. The motor vehicle rim is produced in one piece and continuously in a casting mold by vacuum die casting of a casting material, wherein the motor vehicle rim has a small wall thickness of at most 15 mm at least in some regions and/or a curvature with a small radius of curvature of at most 4 mm.

A disk wheel, comprising a wheel rim (1) and a wheel spoke (2), the inner wall of the wheel rim outer edge (11) is matched with the first wheel spoke convex wall (9), the inner wall of the tire supporting wall (7) is attached to the strengthening wall (8), the groove (5b) is formed in the inner wall of the wheel rim round peak (5), the strengthening wall (8) is provided with the second wheel spoke convex wall (4) in interference fit to the groove (5b), and the groove (5b) is in interference fit to the second wheel spoke convex wall (4), so that the stability of axial matching between the wheel rim (1) and the wheel spoke (2) is guaranteed, and an axial stress, a circumferential stress and a radial stress of the disk wheel in the using process can be effectively addressed.

A wheel disc includes a wheel mounting portion defining a wheel axis, a plurality of spokes radially extending from the wheel mounting portion, and a rim junction on at least one spoke of the plurality of spokes. The rim junction is at an end of the at least one spoke opposite the wheel mounting portion. A first portion of the rim junction extends in an axial direction. Second and third portions of the rim junction extend in a circumferential direction. The axial direction is parallel to the wheel axis and the circumferential direction is in a plane perpendicular to the wheel axis.

A method for producing an automobile rim from aluminum or an aluminum alloy for a wheel of a motor vehicle. The automobile rim has a rim well delimited on opposite sides by an outer flange and an inner flange, a hub having a center recess and a bolt hole circle, and a rim center connecting the rim well and the hub to one another. The automobile rim is produced integrally and continuously in a casting mold by die casting of a casting material. After the introduction of the casting material into the casting mold, a volume of the casting mold is reduced for post-compaction of the casting material. The invention furthermore relates to a device for producing an automobile rim.

The invention relates to a method for producing a fibre composite body (2), in particular at least a part of a wheel, comprising the following steps: providing a mould (4) having at least one female mould part (6) and one male mould part, introducing a fibrous raw material (8) and a binder (10) into the female mould part (6), activating the binder (10) by an energy input (p, T) into the mould (4) to form a mould element (12) which is open to diffusion, joining together the mould element (12) which is open to diffusion and a preform structure (14), supplying a resin, so that the resin infiltrates at least partially into the mould element (12) which is open to diffusion and into the preform structure (14), and curing the resin, so that in this way the fibre composite body (2) is formed without a boundary layer.
