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.

Welded vehicle wheel

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.
