Embodiment Construction

[0031] figure 1 It is a view of the assembly 2 of two elements 4 and 4'made of sheet metal according to the present invention. Each element includes edges 6 and 6', and the edges of the elements overlap to form a flange 8 of the joint of elements 4 and 4'. The edges are assembled by resistance welding points 10 distributed along the flange according to the first axis and by glue tape 12 in the flange extending along the flange according to the second axis. The flange includes a free end 14 (on the right side of the figure) and the second axis is offset relative to the first axis in a direction opposite to the free end 14 of the flange 8. The distance of the first axis of the welding point from the central axis of the flange is less than 30% of the width "D" of the flange, preferably less than 15% of the width, and still more preferably less than 5% of the width. In an alternative embodiment, the first axis of the welding point may correspond to the central axis of the flange. ...

Abstract

The invention relates to an assembly (2) of at least two sheet-metal elements (4, 4') that each comprise an edge (6, 6'), said edges being superposed so as to form a rabbet (8) for joining said elements, said rabbet comprising a free end (14), and said edges being assembled by: - welding points (10) distributed along the rabbet along a first axis; and at least one strip of adhesive (12) in the rabbet, said strip extending along said rabbet along a second axis; the second axis being offset with respect to the first axis in a direction away from the free end of the rabbet. The invention also relates to a method for producing such an assembly (2).

Description

Technical field [0001] The present invention relates to the field of assembly parts of sheet metal, wherein the assembly parts are especially stamped parts of motor vehicles. More specifically, the present invention relates to an assembly of sheet metal forming a flange and a method of manufacturing such an assembly. Background technique [0002] The body structure of a motor vehicle is formed from stamped assemblies that include overlapping edges that form joint feuillures of the stamped parts. The rigidity of the body structure depends partly on the rigidity of the stamping used, and it also partly depends on the rigidity of the joined flanges. A joined flange that lacks rigidity reduces the rigidity of the vehicle body, for example, affecting driving comfort or durability quality. [0003] US 2007 / 0245541A1 discloses an assembly of at least two elements made of sheet metal, each element including an edge. The edges of the elements are stacked to form the joined flanges of the...
