Embodiment Construction

[0029] figure 1 Described is the connection of three hollow profiles H1 , H2 , H3 by T-shaped gussets KT inserted into the ends of the hollow profiles H1 , H2 , H3 . The gusset KT is produced as a cast part containing aluminum or an aluminum alloy and has at its ends a profile matching the cross-section of the hollow profile H1 , H2 , H3 to be received and formed with ribs R. The hollow profiles H1 , H2 , H3 are likewise produced from aluminum or an aluminum alloy.

[0030] figure 2 is a re-delineation of the cross-section through the hollow profile H3 together with the received profiled end of the gusset KT. The profile of the cross section is in figure 1 shown in .

[0031] The ends of the X-profile gusset KT are inserted into the hollow profile H3. The ribs R of the X-shaped gusset KT contact the inner surface of the hollow profile H3. In said contact area, a connection V produced by friction stir welding is formed between the wall of the hollow profile H3 and the ri...

Abstract

The invention describes a hollow profile connection for connecting at least two hollow profiles, comprising a gusset (KT) whose end pieces can be inserted into hollow profiles (H1, H2, H3) , where at least the end piece of the gusset (KT) assigned to the end of the hollow profile (H1, H2, H3) has a profile formed by a web or rib (R), wherein the gusset (KT) and the hollow profile ( H1, H2, H3) are connected to each other by friction stir welding, and where the connection (V) produced by friction stir welding is between the hollow profile (H1, H2, H3) and the gusset (KT) along the gusset (KT) rib or web (R) extension.

Description

technical field [0001] The invention relates to a hollow profile connection for connecting at least two hollow profiles, comprising a gusset part, the end pieces of which can be inserted into the hollow profiles, wherein at least one hollow profile end is assigned The end piece of the gusset part of the section has a profile formed by webs or ribs, wherein the gusset part and the hollow profile are connected to each other by friction stir welding, and wherein the connection produced by friction stir welding is between the hollow profile and the gusset part between the ribs or webs of the gussets. Background technique [0002] Metal hollow sections are frequently and efficiently joined by means of gussets arranged between the sections and subsequently joined to the sections by welding. For weight reasons, in motor vehicle construction generally hollow profiles made of aluminum are used, as are the gussets made of aluminum. [0003] During conventional weld formation, high h...
