Abstract

See full text

A hollow-bodied component, which includes at least two die-cast shell elements (1, 2), is suitable in particular for use as a steering component in motor vehicle running-gear assemblies. The hollow-bodied component has a connection zone (5, 6, 18, 19) configured on the shell elements (1, 2) to be interconnected. One connection zone (5) has one first contact area (7) with an essentially U-shaped cross-section that is located on the respective shell element (1) and the other connection zone has at least one strut-type second contact area (8) that engages in the space in the U-shaped first contact area (7) and that is located on the respective other shell element (2). The connection zones (5, 6, 18, 19) are joined in a force fit in a cold welding process that uses a contact pressure (F.sub.1, F.sub.2), whose value is a multiple of the separating force components (F.sub.r) that act on the connection zones (5, 6, 18, 19) during operation. A method is provided for producing the component.
