A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

A wheel includes a rim that is at least partially made from a fiber reinforced plastic. The rim has an inner side extending to the hub region of the wheel and an outer side extending centrifugally away from the hub region of the wheel whereby the outer side includes a well which is interconnected with an outer shoulder by a transition area. A wheel center is interconnected with the inner side of the rim by at least one fastener wherein the at least one fastener penetrates the rim via at least one opening that extends from the inner side of the rim to the outer side of the rim. An annular cover is arranged at the outer side of the rim in a circumferential direction around the wheel and thereby covers the at least one fastener and/or the at least one opening.

A lightweight wheel spoke for an automobile increases the strength around the heat dissipation holes by thickening the material around the heat dissipation hole on the inner wall of the spoke. The thinning of the material between the heat dissipation holes, that is where there is no heat dissipation holes on the tapered barrel, enables the tapered barrel of the spoke to form a unique concave-convex structure on the inner wall or the outer wall, thereby enabling the entire spoke to be secured.

A wheel for supporting tires for vehicles which is made of composite material based on carbon fiber, which includes an insert which is made of metallic material at its central region configured to be fixed to the hub of the respective vehicle. The insert is coupled between external contoured laminated shells made of composite material, with the interposition of at least one interface film having a thickness that can vary between 0.05 mm and 1.0 mm. The interface film is made of a material preferably chosen from among epoxy polymers, polyurethane polymers, acrylic polymers, silicone polymers, polyamide polymers, glass fibers, and combinations thereof.

A wheel disc comprises 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 wheel design face in a three-dimensional shape is decorated only with a two-dimensional move of one of a discharge nozzle and a holding member, and inclination of the other one of the discharge nozzle and the holding member.

A vehicle wheel decoration method includes a setting step of detachably holding a wheel body in the holding member such that the wheel design face faces the discharge nozzle, and a decoration step of forming a decorative layer on the wheel design face by discharging paint from a discharge opening of the discharge nozzle toward the wheel design face while relatively moving the discharge nozzle in two directions which extend along the wheel design face and cross each other with respect to the wheel design face of the wheel body held in the holding member, and, in the decoration step, the wheel body is relatively inclined in a direction which crosses moving directions toward the two directions by a relative move of one of the discharge nozzle and the holding member or relative moves of both of the discharge nozzle and the holding member, and the discharge opening of the discharge nozzle is relatively moved in the two directions along the wheel design face, a distance from the discharge opening to the wheel design face falling within a predetermined range.
