Problems solved by technology

[0003] The methods used to achieve joints at nodes are complex and require many welding operations between different parts
Moreover, the bending strength and resistance to torsional stresses of the box-type structures at the joints are not ideal; in the case of protruding edges, this is even worse, spot welding is usually performed at a certain distance from the box-type structures due to the size of the devices used, This means that due to the arms formed by the flanks, the welded joint is subject to considerable torsional stress and bending or pulling forces

Embodiment Construction

[0023] Figures 1, 2 and 3 describe a box-type system comprising the top cross member of a truck cab and its associated assembly steps. The transverse member 1 constitutes the first box member, the longitudinal box systems 2 and 3 constitute the second and other box members. The front cross member comprises longitudinal walls 4 and 5 , which in this embodiment have an L-shaped cross-section, eg longitudinal wall 4 consisting of flaps 6 and 7 . Referring to Figure 2, the ends 8 and 9 of the first longitudinal wall 4 overlap the box members 2 and 3 respectively and are joined by known methods, preferably by spot welding. It is possible to weld only one of the fins, for example the fin 6, or also weld the overlapping area of ​​the fin 7 at the same time.

[0024] In Figures 2 and 3, each end of the second longitudinal wall 5 overlaps and engages the ends 10 and 11 of the longitudinal member.

[0025] According to a preferred embodiment, the first and second longitudinal walls ar...

Abstract

Box-type structure for the cab of a truck characterized in that it comprises: a first box-type member (1) comprising two longitudinal walls (4, 5, 21, 22) having a cross-section that forms a bend or a curve; a second box-type member (2, 3, 23, 24) joined to each of said walls by means of the partial overlapping of an end portion thereof (8, 9, 10, 11, 23, 24) and one end of said wall. Method of producing said box-type structure by welding the parts of subassemblies along the junction plane without the need for folded flaps.

Description

technical field [0001] The present invention relates to a box-shaped structure used in the manufacture of vehicle body structures such as vehicles, passenger cars, trucks, and trucks. The box-shaped structure is used as a structure of the vehicle cab, and to a manufacturing method of the box-shaped structure. Background technique [0002] Vehicle bodies, such as truck cabs, typically contain a box-like section that is part of the wall, floor and roof structure. Said box-shaped sections are provided at the corners of the structure, especially at the corners joining the top and the walls, and the box-shaped sections are joined to, or partly formed from, metal sheets constituting the walls and roof, and have the desired strength. These box structures are tubular structures with square or rectangular cross-sections intersecting each other in a series of nodes. For example a roof usually comprises a front cross member and two vertical members, wherein the cross member is arrang...
