According to the invention, it is proposed that the region of the longitudinal edges of the cold-slit strips is heated in a depth in the strip width of at least 1 mm to a maximum of 10 mm in such a way that a temperature of over 150° C. is reached over a time span of more than 0.1 seconds to a maximum of 10 seconds.

Abstract: A welded vehicle wheel includes a center or wheel disc and a rim. The center has a side wall area at an outermost circumference of the wheel disc having an increasing diameter toward an inner side of the welded vehicle wheel. A substantially axially disposed circumferential portion is connected to the inner end of the side wall area. The rim includes a bed region with a decreasing diameter toward the outer side of the welded vehicle wheel. In the assembled state, the rim is connected to the center by a press fit between the outer side of the circumferential portion and the bed region and by a welded seam between the free-end of the circumferential portion and the bed region. The press fit and welded seam form a space therebetween that is circumferentially continuous and expands in cross-section toward the inner side of the welded vehicle wheel.

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.

Abstract: A light-metal strip wheel, in particular for motor vehicles, which includes a wheel disk and a rim. The wheel disk comprises two wheel-disk parts each having a ventilation hole. The ventilation holes have necks that when pressed into one another, secure together the two wheel-disk parts with the two parts separated from one another in the region surrounding the ventilation holes, while coming to rest on one another in a hub region. The space between the two wheel-disk parts in the region surrounding the ventilation holes increases the stiffness of the strip wheel so that the wheel is suitable for accommodating large loads.
