Problems solved by technology

However, the structure does not guarantee precise positioning between stringers and profiles
In addition, such structures are still fragile, making it more difficult to meet the criteria for mechanical strength

Embodiment Construction

[0037] In the following description, the longitudinal axis corresponds to the direction of motion of the vehicle and / or the main dimensions of the structure. The transverse direction is perpendicular to the longitudinal axis. Front corresponds to the main direction of motion of the vehicle.

[0038] figure 1 A bottom view of the structure 4 of the vehicle is shown. The structure 4 may form the platform of a motor vehicle, for example a commercial vehicle. The structure may form part of the vehicle body. The platform may be covered by a partition 6, such as a common floor, which may extend over the entire surface of the platform.

[0039] The structure 4 may comprise a plurality of units, including a first unit or front unit 8 and a second unit or rear unit 10 . An engine mount may be provided in front of the first unit of the structure. The structure 4 may show a frame 12 having two generally parallel beams 14, each beam 14 may be formed from a plurality of elements. Th...

Abstract

The subject of the invention is a utility vehicle platform structure. The structure comprises a wall (6) such as a floor of the vehicle; two girders (14) for reinforcing the wall (6) such as the body framework longitudinal member longerons. Each girder (6) comprises two elements (20; 24) with U-shaped profiles, with a base (34) and two flanges (36), the girders (14) being nested one inside the other. In each girder (14), the base (34) of the first element (20) comprises a portion (38) which is offset from the overall level of said base (34) as far as the base (34) of the second element (24) so as to position the elements (20; 24) vertically relative to one another. The elements (20; 24) have a flat top surface to which weld the wall.

Description

technical field [0001] The invention relates to the structure of motor vehicles. More specifically, the present invention relates to the structure of a motor vehicle platform reinforced by machine-welded U-shaped beams. The invention also proposes a motor vehicle of commercial type. Background technique [0002] Structures of motor vehicles, especially commercial vehicles, often have a loading platform. This can be achieved with multiple sections, ie multiple sheets connected axially. The platform advantageously has a flat loading surface for accommodating bulky components. For strength, beams are added below to withstand the bending forces in the structure. Fixing is advantageously achieved by welding to connect the elements to each other. [0003] Document FR 2 775 243 A1 discloses a welded motor vehicle body. The panels of the floor are welded to parallel U-shaped profiles (profiles). These U-shaped profiles are embedded between transversely outwardly arranged U-sh...
