Description
Die vorliegende Erfindung betrifft ein aufpralldämpfendes Bauelement im Stoßfängerbereich von Kraftfahrzeugen gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to an impact absorbing component in the bumper area of motor vehicles according to the Preamble of claim 1.
Ein
derartiges Bauelement beschreibt zum Beispiel die
Aufgabe der vorliegenden Erfindung ist es, ein baulich einfaches, fertigungstechnisch günstiges und in der Funktion weiter verbessertes Deformationselement für aufpralldämpfende Bauelemente bereitzustellen.task The present invention is a structurally simple, manufacturing technology favorable and in the function further improved deformation element to provide for impact damping components.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte und besonders zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen aufgeführt.These Task is according to the invention with the features of claim 1. Advantageous and special expedient developments of the invention listed in the subclaims.
Erfindungsgemäß wird vorgeschlagen, dass das Deformationselement über seine Länge mit etwa in Fahrzeuglängsrichtung ausgerichteten Schlitzen versehen ist, wobei die Schlitze von den am Querträger befestigten, etwa horizontal verlaufenden Schenkeln des Deformationselementes in das etwa vertikal verlaufende Basisblech übergehen. Damit gelingt es, neben der baulich einfachen und fertigungstechnisch günstigen Gestaltung des Deformationselementes dieses so auszubilden, dass örtliche Beaufschlagungen – wie sie insbesondere bei Kollisionen mit Fußgängern auftreten – wirkungsvoll absorbiert und gleichmäßig in den Stoßfängerbereich eingeleitet werden. Belastungsspitzen über den verwirklichbaren Deformationsweg können dadurch weitgehendst vermieden werden.According to the invention suggested that the deformation element over his Length aligned approximately in the vehicle longitudinal direction Slots is provided, with the slots of the cross member attached, approximately horizontally extending legs of the deformation element go over into the roughly vertical base plate. This makes it possible, in addition to the structurally simple and production technology favorable Design of the deformation element of this form so that local Exposures - as in particular in collisions with pedestrians - effective absorbed and evenly into the bumper area be initiated. Load peaks over the realizable Deformationsweg can thereby be largely avoided.
Das Deformationselement kann fertigungstechnisch einfach einstückig aus einem dünnwandigen Blech gebildet sein und in einem Biege- oder Tiefziehprozess einer Formgebung unterworfen werden.The Deformation element can easily be manufactured in one piece be formed from a thin-walled sheet and in one Bending or deep drawing process to be subjected to a shaping.
Des Weiteren wird vorgeschlagen, dass die Randbereiche der Schenkel den Querträger überlappen und an diesen angeschweißt sind. Die Schlitze können außerhalb oder innerhalb des Überlappungsbereiches beginnend zum Basisblech verlaufen. Damit bildet das Deformationselement eine funktionell günstige Montageeinheit mit dem Querträger, die zudem eine günstige Energieverteilung und ein konstantes Beschleunigungsniveau bei höheren Aufprallgeschwindigkeiten ermöglicht.Of Furthermore, it is proposed that the edge regions of the legs overlap the cross member and welded to this are. The slots can be outside or inside of the overlap region starting to the base plate. Thus, the deformation element forms a functionally favorable Mounting unit with the cross member, which also has a cheap Energy distribution and a constant acceleration level at higher Impact speeds allows.
Besonders bevorzugt können sich die Schlitze von den Schenkeln des Deformationselementes aus soweit in das Basisblech erstrecken, dass ein quer verlaufender, nicht unterbrochener Mittelabschnitt gebildet ist. Der Mittelabschnitt wirkt somit wie ein Gurt, mittels dem eine örtlich einwirkende Aufprallenergie verbessert auf benachbarte Abschnitte des Deformationselementes einleitbar ist.Especially Preferably, the slots of the legs of the Deformationselementes from so far in the base plate extend that a transverse, uninterrupted central portion is formed is. The middle section thus acts like a belt, by means of a locally acting impact energy improves on adjacent sections of the deformation element can be introduced.
Der nicht unterbrochene Mittelabschnitt kann dabei bevorzugt in seiner Höhe etwa einem bis zwei Drittel der Höhe des vertikal verlaufenden Basisblechs des Deformationselements entsprechen.Of the uninterrupted middle section may preferably be in his Height about one to two thirds of the height of the correspond vertically extending base plate of the deformation element.
In vorteilhafter Weiterbildung der Erfindung können ferner die Schlitze in dem oberen und dem unteren Schenkel des Deformationselementes zueinander versetzt liegen, so dass jeweils ein Schlitz einem zwischen den Schlitzen gebildeten Steg des anderen Schenkels gegenüberliegt. Daraus resultiert eine noch homogenere Verteilung der Aufprallenergie auf die betroffenen Bereiche des Deformationselementes.In Advantageous development of the invention may further the slots in the upper and lower legs of the deformation element offset from each other, so that in each case a slot between opposite to the slots formed web of the other leg. This results in an even more homogeneous distribution of the impact energy on the affected areas of the deformation element.
Weitere vorteilhafte Ausgestaltungen der Erfindung bestehen darin, dass die Breite der Schlitze geringer ist als die Breite der benachbarten Stege, dass ferner die Breite der Stege zumindest das Zweifache der Breite der Schlitze beträgt und dass schließlich das Basisblech des Deformationselementes mit gerundeten Übergängen in die Schenkel übergeht. Damit gelingt es, das Bauelement und insbesondere dessen Deformationselement noch weitergehender an gegebene konstruktive Verhältnisse des Stoßfängerbereiches beziehungsweise des Kraftfahrzeuges zur Erzielung gewünschter Kraft-Weg-Kennlinien anzupassen.Further advantageous embodiments of the invention are that the width of the slots is less than the width of the adjacent ones Webs, that further, the width of the webs at least two times the width of the slots is and that eventually the base plate of the deformation element with rounded transitions goes into the thighs. This succeeds, the component and in particular its deformation element even further to given structural conditions of the bumper area or the motor vehicle to achieve desired force-displacement characteristics adapt.
Ein Ausführungsbeispiel der Erfindung ist im Folgenden mit weiteren Einzelheiten näher erläutert.One Embodiment of the invention is hereinafter with further details explained.
Die beiliegende Zeichnung zeigt in raumbildlicher Darstellung abschnittsweise einen Stoßfänger-Querträger mit daran befestigtem Deformationselement für ein Kraftfahrzeug, in einer Ansicht von schräg vorne.The Enclosed drawing shows in space pictorial representation in sections a bumper cross member with it fastened deformation element for a motor vehicle, in a view from diagonally forward.
