  • Patent number: 5971496
    Abstract: A vehicle having a rim and a wheel disk center or convex wheel disk which is connected thereto and is secured by a hub or brake drum with a plurality of connection bosses for the wheel bolt holes arranged along the circumference of the bolt pitch circle. The connection bosses have a spherical or conical countersink, and the region surrounding the countersink is cambered outward. The wheel disk center or convex wheel disk has contact surfaces for the hub or brake drum which are distributed along the circumference. The region of the connection boss which surrounds the countersink, is significantly thicker in all cross-sectional planes than the more remote region which forms the wheel disk center or convex wheel disk. The region surrounding the countersink forms an integral unit with the more remote region.
