A wheel bearing device for a motor vehicle, having an inner ring arrangement, formed for rotationally fixed reception of a first rotary partner, particularly an axle stump, or a shaft, an outer ring arrangement, which is connected and/or connectable and rotationally fixed with a second rotary partner, a multitude of rolling elements, which roll between the inner ring arrangement and the outer ring arrangement, so that inner ring arrangement and outer ring arrangement and/or the rotary partners are rotatable against each other, and an electric sensor device, which, using mechanical contact, is arranged and/or formed for detecting an operating status of the wheel bearing device. The sensor device has a stationary sensor element and a rotating sensor element, which can work together to form the mechanical contact. One of the sensor elements is connected with the inner ring arrangement without the interposition of the first rotary partner.

A method for connecting shell parts (), which have been formed from sheet metal, for example by deep drawing. The shell parts () may be any desired workpieces of a chassis part in the form of semifinished items or other components that are suitable for a folded seam connection. For this, the shell parts must have edges which are arranged lying one against the other in the connecting position. The method according includes first arranging the shell parts () that are to be connected in a position envisaged for the shell parts () in the connected state. Subsequently, the edge () of the first shell part () is folded around the edge () of the second shell part (), so that a folded seam () is formed. After the folding operation, according to the invention the folded seam () is heated and subsequently once again pressed together. As a result, a positive and gap-free folded seam connection is achieved, with which the shell parts () are permanently firmly connected.
