Abstract
The present invention relates to a method for producing a link unit, comprising the steps of provision of a carrier, reshaping of the carrier in the region of a first connecting section in such a way that an upset section is formed, the wall thickness of the carrier being increased in the region of the upset section, and provision of a node element with a joint section, and connecting of the joint section to the first connecting section by means of a rotary friction welding method. Furthermore, the invention relates to a link unit, in which a carrier which is configured in the manner of a hollow body is connected to a node element by means of a rotary friction welding method.
Claims19
A method for producing a link unit, comprising:
- providing a carrier which has a first connecting section;
- cold forming the carrier in a region of the first connecting section to form an upset section, the wall thickness of the carrier being increased in the region of the upset section;
- providing a node element with a joint section;
- and
- connecting the joint section to the first connecting section by rotary friction welding, and
- wherein the carrier includes a second connecting section at an end of the carrier which lies opposite the first connecting section, on which second connecting section a bearing socket is fixed.
A link unit for a vehicle, comprising:
- a carrier;
- and
- a node element;
- wherein the carrier includes a hollow body and a tubular section and an upset section adjacent to the tubular section;
- wherein the upset section has a greater wall thickness than the tubular section;
- wherein the node element is configured to be fixed on the carrier by rotary friction welding on a side of the upset section which faces away from the tubular section;
- and
- wherein the carrier has a structure strength which is increased by cold forming a region between the tubular section and the upset section.
