A variable thickness rim structure made of carbon fiber composite includes an outer ply block, that is paved as an outer side of the rim structure; an upper ply block, that is paved as an upper part of an inner side of the rim structure; a lower ply block, that is paved as a lower part of the inner side of the rim structure; a filling ply block, that is paved among the outer ply block, the upper ply block, and the lower ply block, where a first end of the upper ply block and a first end of the lower ply block extend inwards to form an annular connecting flange; a second end of the upper ply block extends upwards and a second end of the lower ply block extends downwards to form a rim ring together with the outer ply block.

The invention relates to a component in the form of a wheel comprising: a hub portion, a rim portion with an outer rim flange and an inner rim flange, a plurality of circumferentially distributed spokes extending between the hub portion and the rim portion, wherein the spokes and the hub portion are arranged offset with respect to a wheel center plane towards the outer rim flange and have an inner side facing the wheel center plane and an outer side directed away from the wheel center plane, wherein the outer rim flange has greater tensile residual stresses at least in a partial region than at least a partial region of the inner rim flange.

A bicycle wheel includes a hub. The wheel also includes a fully asymmetric carbon fiber rim. The carbon fiber rim includes a curved sidewall and a straight sidewall, the straight sidewall being thicker than the curved sidewall. The wheel also includes a number of symmetric left and right spokes connecting the hub to the rim.

A vehicle wheel rim for use on a motor vehicle, having a wheel rim well (1, 29), having an inner wheel rim flange (7, 30) and having an outer wheel rim flange, wherein the wheel rim well (1, 29) is delimited at its axial end regions by in each case one of the wheel rim flanges (7, 30), wherein the wheel rim flanges (7, 30) are formed by a radially encircling wall, said walls extending in each case at a predefinable angle (5, 27) with respect to the wheel rim well (1, 29).

The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

A vehicle wheel includes a rim having mounted thereon an inflation valve and a tire. The inflation valve is extended by an inflation channel extending through the rim and opening out into a volume of gas defined by the rim and the tire. The inflation valve is arranged in the vicinity of a flange of the rim.

A device for quenching a wheel includes at least one hub outer cooling unit for quenching the outer side of a hub portion of the wheel; at least one hub inner cooling unit for quenching the inner side of the hub portion; at least one spoke outer cooling unit for quenching outer sides of the spokes, and at least one rim cooling unit for quenching the rim portion. The cooling units are each configured to spray a cooling medium onto the wheel and are independently controllable by a control unit.

A method for producing a motor vehicle rim made of an aluminum alloy for a wheel of a motor vehicle, the motor vehicle rim having a rim base limited 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. The motor vehicle rim is produced in one piece and continuously in a casting mold by die casting of a casting material, the casting material being the aluminum alloy.

Disclosed is a wheel rim with composite rim flanges, and under the premise of meeting a GB/T 3487 dimension standard, the wheel rim (10) with the composite rim flanges divides rim flanges into at least two parts, wherein one part is a flexible rim flange (20) located at an outermost circumference of the rim flanges, and the other part is a half-height rim flange (14) located at an inner side of a circumference of the flexible rim flange; maximum diameters of inner and outer rim flanges of the wheel rim (10) with the composite rim flanges are the same or in a tolerance range; and the flexible rim flange (20) is mainly composed of an elastomer material and a reinforced framework. A hardness of the elastomer material is less than 30% of a hardness of the half-height rim flange, but the elastomer material is very tough.
