Patent ID: 7722280

Claim:
A hollow body component to be subjected to operation forces having a separating force component acting on the hollow body, the hollow body component comprising: a first shell element made of diecast material, said first shell element having a first shell element connection area; a second shell element made of diecast material, said second shell element having a second shell element connection area, said first shell element connection area comprising a first contact area having an essentially U-shaped cross section, said second shell element connection area comprising a web-shaped second contact area, said web-shaped second contact area being inserted into and engaging a space of said U-shaped first contact area in a joining direction of said first shell element, said first shell element connection area being cold-welded to said second shell element connection area in a non-positive manner by applying a pressing force which is several times stronger than the separating force component, said first shell element and said second shell element being provided with a common, positive-locking coupling device comprising: a first junction area arranged on said first shell element and having a first central longitudinal axis; a second junction area arranged on said second shell element and having a second central longitudinal axis, said first central longitudinal axis being aligned with said second central longitudinal axis to form a common center line perpendicular to said joining direction, each of said first junction area and said second junction area having an essentially annular cross section to define essentially annular cavities, said essentially annular cavity of said first junction area being in communication with said essentially annular cavity of said second junction area to define a plug-in element receiving cavity; and a plug-in element comprising an outer ring of a bearing component, said plug-in element receiving cavity receiving said plug-in element such that said plug-in element connects said first junction area and said second junction area in a positive-locking manner, with said plug-in element passing through said essentially annular cavities.
