Abstract
Description
Die Erfindung betrifft eine Crashstruktur im Endbereich eines Kraftwagens der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a crash structure in the end of a motor vehicle in the preamble of claim 1 mentioned type.
Aus der
Aufgabe der Erfindung ist es, eine Crashstruktur im Endbereich eines Kraftwagens der im Oberbegriff des Anspruchs 1 genannten Art dahingehend weiterzuentwickeln, dass ein besonders kompakter Aufbau der Crashstruktur möglich ist.The object of the invention is to provide a Crash structure in the end of a motor vehicle in the preamble of claim 1 to further develop that a particularly compact structure of the crash structure is possible.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the Characteristics of claim 1 solved.
Weitere die Erfindung in vorteilhafter Weise ausgestaltende Merkmale enthalten die Unteransprüche.Further the invention in an advantageous Way ausgestaltende features include the dependent claims.
Der mit der Erfindung erzielte Vorteil besteht darin, dass sich der notwendige Abstand zwischen dem Biegequerträger und einer Quertragstruktur der Karosserie deutlich verkürzen lässt, da ein Teil der Aufprallenergie durch eine elastische Durchbiegung des Biegequerträgers absorbiert werden kann. Hierzu lässt sich der Biegequerträger durch eine drehbewegliche Lagerung an den Druckstreben besonders biegeweich auslegen. Eine plastische Deformation des Biegequerträgers kann bei einem Aufprall mit kleiner Fahrgeschwindigkeit zuverlässig vermieden werden, da eine Aufprallzone des Biegequerträger zumindest ab einer konstruktiv vorgegebenen elastischen Durchbiegung an einer steifen Quertragstruktur der Karosserie abgestützt ist.The advantage achieved with the invention is that the necessary distance between the bending cross member and a Querg Structure of the body significantly shorten, since part of the impact energy absorbed by an elastic deflection of the bending cross member can be. To do this the bending cross member particularly flexible due to a rotatable mounting on the struts interpret. A plastic deformation of the bending cross member can be reliably avoided in a collision with low driving speed, since an impact zone of the bending cross member at least from a constructive predetermined elastic deflection on a stiff transverse support structure supported the body is.
Um insbesondere bei Stößen auf den mittleren Bereich des Biegequerträgers zwischen den Drehgelenken die Absorption der Aufprallenergie weiter zu verbessern, kann zwischen der Aufprallzone des Biegequerträgers und der Quertragstruktur der Karosserie ein Energie-Absorptions-Element angeordnet sein. Zur zuverlässigen Absorption auch sehr kleiner Stöße, kann das Energie-Absorptions-Element dabei ständig zwischen der Aufprallzone des Biegequerträgers und der Quertragstruktur der Karosserie abgestützt sein. Als besonders einfaches und zuverlässiges Energie-Absorptions-Element kann ein Schaumkörper vorgesehen sein.Especially on bumps the middle region of the bending cross member between the hinges To further improve the absorption of the impact energy can take place between the impact zone of the bending crossmember and the transverse support structure of the body an energy absorption element be arranged. To reliable Absorption of very small bumps, too the energy absorption element constantly between the impact zone of the bending crossmember and the transverse support structure of the body be supported. As a particularly simple one and reliable Energy absorption element may be provided a foam body.
Als Druckstreben können z. B. besonders zuverlässige teleskopartige Stoßdämpfer eingesetzt werden. Alternativ können besonders kostengünstigere biegeelastische Diagonalstreben vorgesehen sein.As pressure struts z. B. particularly reliable telescopic shock absorbers are used. Alternatively you can especially cheaper bending elastic diagonal braces be provided.
Nachfolgend werden Ausführungsbeispiele der Erfindung anhand einer zeichnerischen Darstellung näher erläutert.Hereinafter, embodiments of the Invention explained in more detail with reference to a drawing.
