Embodiment Construction

[0024] figure 1 A perspective view showing a vehicle front structure according to the invention. The front structure comprises a bumper beam 1 extruded from aluminum or an aluminum alloy. exist figure 1 Only the right-hand end portion of the bumper beam 1 is shown in FIG. The bumper beam 1 comprises a front wall 2 , a rear wall and three walls 4 , 5 , 6 extending between the front wall 2 and the rear wall and defining upper and lower compartments 7 , 8 . The rigidity of the front wall 2 is increased by two grooves 3 formed therein, which extend horizontally over the entire length of the bumper beam 1 .

[0025] exist figure 1 The rear wall, which is not visible from the perspective of , is fastened to the front end of the chassis side members 9 , which in turn extend essentially over the entire length of the body. The floor stringer 9 has a central section 10 consisting of two thick-walled rigid sheet metal parts, which are joined together to form a cavity profile. A hoo...

Abstract

A vehicle front structure comprising a bumper beam (1) designed as a hollow body with an open end and an extension (13) inserted into the open end.

Description

technical field [0001] The invention relates to a front structure for a motor vehicle comprising a bumper beam and extensions connected to the transverse ends of said bumper beam. Background technique [0002] Document DE 10 2010 014 999 A1 proposes a front structure of the above-mentioned type. [0003] According to this document, when combining one type of bumper beam with different types of extensions, vehicle front structures for different widths can be constructed by using a small number of different parts. [0004] The problem with this conventional front structure is its three-part construction. If a car equipped with such a front structure collides with an obstacle, and if the overlap between the car's front structure and the obstacle is small, one of the extensions takes most of the force of the collision, the extensions are likely to be disengaged The bars, and the wheels behind the extensions will be pressed directly against the front wall of the car's cabin. ...
