Motor vehicle body work - has support of light metal, extruded hollow profiles with sections in which light metal cast parts are welded

摘要

The walls of the hollow profiles at the points in the bodywork where there are cross-section variations and/or functional parts have sections in which a light metal cast part (13) of corresponding shape is welded. This cast part locates with its edge on the edge limiting the section and it is to this edge that it is welded. The cast part has threads for functional parts (18, 19) and is also welded to a central column (11), its threaded holes accommodating a lock bolt for the door lock of the front door and fixture screws for a functional part of the rear door. USE - As a bodywork structure of a motorcar.
