Abstract: A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the front surface has a relatively smooth profile and the rear surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

Abstract: A wheel disc for vehicle wheels manufactured by flow forming, in particular for passenger cars, which has a stretched disc transition surface subsequently provided with ventilation holes and a radial outer disc edge. All ventilation holes are located in the transition surface and are attached by punching or cutting. In order to improve the competitiveness of vehicle wheels made of steel or other materials suitable in particular for cold forming compared to cast vehicle wheels made of aluminium, the transition surface is provided with several changes in material thickness generated during flow forming by displacement of the tool and, viewed in the radial direction, effecting a wave structure on the surface facing the tool during flow forming. The surface provided with the wave structure can in particular form the non-visible inner side of a vehicle wheel, but can also form the visible side. In addition, the opposite surface can also be provided with a wave structure.

Abstract: A vehicle rim including outboard and inboard bead seats and an annular well flank connected to the outboard bead seat and extending radially inwardly and towards the inboard side of the rim. A well base is connected to the well flank, wherein the well base defines a flat profile, and wherein the well base defines the inner-most radial dimension of the rim. A transition portion is defined between the well flank and the inboard bead seat. The transition portion has a circumferential corrugated profile having a circumferentially concave-shaped outboard groove connected to the well base at a first tangency point, a circumferentially convex-shaped ridge directly connected to the outboard groove at a second tangency point, and a circumferentially concave-shaped inboard groove directly connected to the ridge at a third tangency point. The inboard groove is connected to the inboard bead seat at a fourth tangency point.

Abstract: A vehicle wheel comprises a wheel disc, wheel rim, and wheel axis. A first cover spans between the rim and a hub portion of the disc. An axial portion of the first cover extends substantially along the axis. A plurality of first vents in the axial portion are arrayed circumferentially about the axis. Tabs extend perpendicular to the axial portion at each of the first vents. A second cover is secured to the rim and extends radially inward from the rim in a direction perpendicular to the axis. A plurality of second vents are in the second cover and arrayed circumferentially about the axis. The first and second covers are on opposite sides of the wheel. Each of the first and second covers has a greater extent in a radial direction perpendicular to the axis than in an axial direction parallel to the axis.

Abstract: 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.

Abstract: A wheel disc including a hub located centrally within the wheel disc and defining a wheel axis. The hub has a plurality of bolt holes formed therein. The wheel disc further including an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a plurality of vent holes formed therein. The transition portion has a front surface and a rear surface defining a thickness therebetween such that the thickness of the transition portion varies in the radial direction.
