Embodiment Construction

[0027] The assembly according to the invention makes it possible to obtain compact, lightweight, strong parts on which the suspension elements can be easily fitted.

[0028] The design according to the invention is based on the choice of producing an aluminium casting that allows the connection between the side rails and the brackets of the vehicle body structure, while providing the necessary fasteners for the suspension elements. As a result, the anti-bending bar, lower suspension triangle and clamping rocker can be securely fastened to the casting with ample interfaces. The casting process associated with the machining operation offers a great deal of freedom in the form allowed and its precision. Furthermore, the use of castings makes it possible to integrate all functions in a minimal amount of space, thus complying with vehicle architectural constraints.

[0029] In the embodiments described below by way of illustration of a vehicle with rear wheel drive, it will be und...

Abstract

The invention relates to a body structure comprising at least one aluminium side rail (10, 20) which allows the assembly of an aluminium bracket (30) of a vehicle by means of an aluminium casting (50, 60) comprising a The upper surface (51, 61) below the side rails (10, 20), one or more lower parts (52, 53, 62, 63) attached to the bracket (30), and allowing the passage of the drive shaft openings (54, 64). The casting may also contain suspension interfaces.

Description

technical field [0001] The present invention relates to an assembly of a bracket on a vehicle body, in particular a motor vehicle body, comprising a casting. Background technique [0002] For lightweight reasons, the billet body of the vehicle is made of aluminium. Especially for parts that are exposed to high levels of mechanical and / or thermal stress, the underbody of the vehicle body mainly consists of a combination of aluminium profiles assembled by gluing, riveting and / or welding. [0003] The aim is to obtain a solution for the assembly of the bracket with the underbody, and in particular of the rear bracket with the rear side rails of vehicles in which the engine assembly is arranged at the rear. It must also be possible to assemble the suspension functions in this area. [0004] In general, vehicles are designed by assembling steel stampings. In fact, steel can be stamped easily and strong parts can be obtained. Thus, the rear support and the side rails form a st...
