Abstract
A wheel, particularly a light metal wheel, for motor vehicles, essentially consists of a spoke wheel center (20) and a wheel rim (10). In order to reduce weight and to increase the bending strength, which is of great significance in regard to contacts with curbstones and driving through potholes, profile segments (31) in the form of half-shell units, which from a continuous hollow chamber (41) in the direction of circumference, at least in sections, are provided in the area of an external base of the rim (14).
Claims6
A wheel, comprising:
- a spoke wheel center (20) and a wheel rim (10);
- wherein the wheel rim (10) further comprises an internal bead seat (16) and an external bead seat (14) which each make a transition into an internal flange (18) and an external flange (12);
- wherein profile segments (31, 32, 33, 34, 35, 36), which continuously form at least one hollow chamber (41, 42, 43, 44, 45, 46, 47) in the direction of circumference, at least in sections, are provided proximate the internal bead seat (16) and/or of the external bead seat (14);
- wherein the spoke wheel center (20) and the wheel rim (10), including the inner and outer flanges, and inner bead seat, form a first component of the wheel;
- and wherein the profile segments (31, 32, 33, 34, 35, 36) are configured as second components, separate from the first component of the wheel, and subsequently affixed thereto.
