Embodiment Construction

[0033] figure 1 and figure 2 It has been briefly described above by way of illustration of the prior art. meaningfully in figure 2 As seen above, the extrusion of the profile 4 comprises an open cavity 14 at its rear edge. exist figure 1 It can be seen from above that the horizontal upper and lower walls of this cavity serve as fastening means for fixing to the axle by means of holes in the end of the profile. It can also be observed that at the central part of the profile 4 the material of these walls has been removed in order to gain access to the bottom wall of the cavity 14 intended to serve as a fitting wall for the fitting support 12 .

[0034] The principle of the invention consists in the direct production of the support of the fastening part in the mass of the profile during extrusion and the subsequent removal of excess material.

[0035] image 3 and Figure 4 A first embodiment according to the invention is shown. In the sectional view of the profile 104 ...

Abstract

The invention relates to a supporting structure (102) of a motor vehicle, such as a cradle for the chassis-suspension system of the vehicle, the structure (102) comprising an extruded profile member (104). The extruded portion of the profile member comprises, on one or more segments of said profile member, a chamber (114) projecting from said portion to near said segment or segments, said chamber forming a receiving portion (112) for an attachment means (108). For this purpose, the material of the profile member (104) corresponding to said chamber (114) is removed on either side of said segment or segments. The invention also relates to a method for manufacturing said structure (102) and to a vehicle provided with said structure.

Description

technical field [0001] The invention relates to the field of supporting members of vehicles, such as brackets for supporting the suspension system of the vehicle chassis. The invention relates more precisely to the fastening of peripheral fittings or elements on such components. The invention also relates to a manufacturing method for producing such a component, and to a vehicle equipped with said component. Background technique [0002] A front-drive motor vehicle has a front axle comprising brackets, on the one hand, for fitting the front axle under the chassis of the motor vehicle, and, on the other hand, elements required for securing the front wheels and changing the orientation of the front wheels , a rear-drive vehicle has, in addition to a front axle with a bracket, a rear axle with a bracket for mounting the rear axle under the chassis. [0003] When the engine of the vehicle is located at the front of the vehicle, the exhaust line extends near the bracket and pas...
