Abstract
Description
Die Erfindung betrifft einen Längsträger an Kraftfahrzeugen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a side member on motor vehicles according to the preamble of claim 1.
Aus der Praxis sind Trägeranordnungen an Kraftfahrzeugen bekannt, die sich höhenund/oder seitenversetzt erstrecken, um z. B. Aggregaten auszuweichen oder solche aufzunehmen.Carrier arrangements are practical known on motor vehicles that are offset and / or offset extend to e.g. B. Dodge aggregates or record them.
Ferner ist es bekannt, dass derartige Träger, auch als Längsträger bezeichnet, bei einem Frontalaufprall insbesondere im Bereich der ausgebildeten "Kurbel", wo dieselben vom Vorderwagen ausgehend höhenversetzt nach unten unter das Bodenblech geführt sind, einer erhöhten Knickbeanspruchung unterliegen.It is also known that such Porters, too referred to as the side member, in the event of a frontal impact, particularly in the area of the trained "crank", where the same from The front end is offset in height are led down under the floor panel, an increased buckling stress subject.
Mit der
Ungeachtet dessen ist wenigstens im Bereich der oberen Abwinkelung des Längsträgers mit einem undefinierten Abknicken desselben und einer Deformation des Fußraums zu rechnen.Regardless, at least in the area of the upper bend of the side member with an undefined Kinking and a deformation of the footwell to be expected.
Um diesem Problem zu begegnen, ist
es aus der
Ebenso ist es an sich bekannt, zur

vorzusehen (
Aufgabe der Erfindung ist es nunmehr, einen Längsträger so zu verbessern, dass mit einfachen und kostengünstigen Maßnahmen eine definierte Verstärkung und gegebenenfalls ein vorbestimmtes Knickverhalten desselben im Crashfall erzeugbar ist, mit dem Ziel, eine Deformation des Fußraums des Kraftfahrzeugs weitestgehend zu vermeiden.The object of the invention is now a side member like that improve that with simple and inexpensive measures a defined reinforcement and if necessary, a predetermined buckling behavior of the same in the event of a crash can be generated with the aim of a deformation of the footwell of the motor vehicle to be avoided as far as possible.
Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass dem Längsträger wenigstens im Bereich seiner oberen Abwinkelung ein steifigkeitserhöhender metallener Verstärkungswinkel fest zugeordnet ist.According to the invention, the task is related solved with the features in the preamble of claim 1 in that the side member at least a stiffness-increasing metal in the area of its upper bend reinforcement bracket is permanently assigned.
Der Verstärkungswinkel ist dabei durch einen weitestgehend der Kontur des Profilgrundes des Längsträgers folgenden Boden mit Seitenstegen gebildet und in das Hohlprofil des Längsträgers in einem bestimmten Abstand zum Profilgrund, ein Doppel-Hohlprofil ausbildend, eingebracht. Zweckmäßiger Weise ist der Verstärkungswinkel mit seinen Seitenstegen an den Seitenstegen des Längsträgers befestigt, wobei die korrespondierenden Seitenstege des Verstärkungswinkels und des Längsträgers miteinander verschweißt oder verklebt oder mittels mechanischer Verbindungsmittel, wie Schrauben oder Niete, verbunden sein können.The gain angle is through one largely follows the contour of the profile base of the side member Bottom formed with side webs and in the hollow profile of the side member a certain distance from the base of the profile, forming a double hollow profile, brought in. Appropriately is the gain angle attached with its side webs to the side webs of the side member, the corresponding side webs of the reinforcement angle and the side member with each other welded or glued or by means of mechanical connecting means such as screws or rivets, can be connected.
Vorzugsweise ist der Verstärkungswinkel aus Metallblech oder Metallguß gefertigt.The gain angle is preferably off Made of sheet metal or cast metal.
Die vorgeschlagene Anordnung hat im Hinblick auf den Stand der Technik den wesentlichen Vorteil, dass schon allein der verwendete Verstärkungswinkel eine hohe Eigensteifigkeit aufweist und durch die Doppel-Hohlprofilbildung ausgewählte Bereiche des Längsträgers besonders verstärkt werden können.The proposed arrangement has the main advantage with regard to the state of the art, that the reinforcement angle used alone has a high inherent rigidity and selected areas due to the double hollow profile formation of the side member in particular reinforced can be.
Die Erfindung wird nachstehend anhand des in den Zeichnungen schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The invention is illustrated below of the embodiment shown schematically in the drawings explained in more detail. It demonstrate:
