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