Embodiment Construction

[0032] figure 1 A possible embodiment of a front subframe 100 , in particular a front axle subframe, is shown. The front subframe 100 is preferably U-shaped, wherein a possible embodiment of the crash structure 1 is fastened at the ends of its leg beams 120 , 130 .

[0033] The front subframe 100 serves, for example, to carry a steering gear of a vehicle steering system of a motor vehicle, at least one stabilizer, at least one bearing for the engine mount, a transverse link and an exhaust system. A tie rod 160 is preferably assigned to the front subframe 100 , via which the two leg members 120 , 130 of the front subframe 100 are connected to one another. The tie rods 160 are preferably hinged to the side beams 120 , 130 and serve to improve the rigidity of the front subframe 100 in the area of ​​its side beams 120 and 130 .

[0034] The crash structure 1 , which is connected in each case to the ends of the side beams 120 , 130 of the front subframe 100 , is preferably elonga...

Abstract

The invention relates to a crash structure 1 for attachment to a front subframe 100 for a motor vehicle. At least one stiffening structure 3, which reinforces the crash structure 1 in an attachment area (2 see fig 2) for the front subframe 100, is provided, on which the crash structure 1 is connectable to the front subframe 100 in a friction-locked and / or formfitting manner. Furthermore, the invention relates to a front axle subframe 100 for a motor vehicle. The stiffening structure 3 typically includes two plates (6,7 see fig 2) joined by and welded to an intermediate sleeve (8 see fig 2). The invention is aimed at providing structures consistent with improved steering behaviour in a crash whereby potential effects on wishbone mountings in a situation involving transverse forces are addressed.

Description

technical field [0001] The invention relates to a crash structure for a motor vehicle for connection to a front subframe. The invention also relates to a front subframe for a motor vehicle, in particular a front axle subframe. Background technique [0002] Motor vehicles usually have a so-called front subframe or front axle subframe in the front compartment, which additionally supports the steering gear, stabilizers, engine mounts, transverse links and exhaust system of the vehicle. Viewed along the direction of the car, there are crash structures connected to the front sub-frame on the left long side and the right long side of the front sub-frame respectively, and the crash structure is also called a crash extension (crash extension). The crash structure is designed in the form of a longitudinal beam and is intended to absorb crash energy in the event of a vehicle crash. For this purpose, the crash structure is designed in such a way that it can deform in the event of a c...
