Embodiment Construction

[0033] image 3 The assembly of a front beam 7 and a crash bumper 8 according to the invention fastened to the front of two longitudinal beams 5 is shown, only one of which is visible.

[0034] The front beam 7 consists of two steel plate parts 7a, 7b fixed to each other.

[0035] Such as Figure 4 As shown, each of the two crash bumpers 8 (only one visible) located between the front beam 7 and the plate 6 is constructed of steel plates forming a hollow body expanding from front to rear, the plate 6 is fixed to the two longitudinal beams 5 front.

[0036] According to the invention, the hollow body has undulations 9, 10, 11, 12, 13, 14, the sides of which extend between the front and the rear of the hollow body, i.e. the force generated in the event of a frontal impact. extend in the direction.

[0037] Figure 4 It is also shown that the hollow body is composed of two half-shell-shaped plate parts 8 a , 8 b assembled to each other along the plane of symmetry of the hollo...

Abstract

The invention relates to an assembly comprising a motor vehicle front beam (7) and two front shock absorbers (8) that are each intended to be fixed between one of the two opposite ends of said front beam (7) and a front end of one of the two side members (5), each of these two shock absorbers (8) being formed by a sheet of steel forming a hollow body flared from the front to the rear, characterized in that said hollow body has corrugations, the flanks of which extend between the front and the rear of said hollow body.

Description

technical field [0001] The invention relates to an assembly comprising a front beam of a motor vehicle and two frontal impact absorbers, each of which is fixed to one and both of two opposite ends of the front beam. between the front ends of one of the stringers. [0002] The invention also relates to a motor vehicle underbody front surface comprising an assembly according to the invention. Background technique [0003] figure 1 A perspective view of the underbody front surface of a motor vehicle of known type. [0004] figure 2 for figure 1 Side view of the assembly shown above. [0005] figure 1 The front surface shown above comprises a front beam 1 and two front crash absorbers 2, 3, each of which is fastened to two opposite ends 1a, 3 of the front beam 1. Between one of 1b and the front end of one of the two stringers 4,5. [0006] In the known embodiment, the front beam 1 and the two crash bumpers 2 , 3 are made of aluminum, which makes it possible to reduce th...
