Abstract
Description
Die Erfindung betrifft eine Befestigungsanordnung wenigstens einer Versteifungsstrebe an einem Querträger eines Personenkraftwagens gemäß Oberbegriff des Anspruchs 1.The invention relates to a fastening arrangement of at least one stiffening strut on a cross member of a passenger car according to the preamble of claim 1.
Um die Torsionssteifigkeit der Karosserie zu verbessern und über das Fahrwerk in den Rohbau eingeleitete Kräfte besser aufnehmen zu können, ist es aus dem Kraftwagenbau bereits bekannt, die Federbeindome über jeweilige Versteifungsstreben am Windschutzscheiben-Querträger abzustützen. Eine derartige Befestigungsanordnung ist beispielsweise aus der
Zur Anbindung der Versteifungsstrebe an dem Windschutzscheiben-Querträger ist üblicher Weise eine Befestigungseinrichtung mit einem Konsolenelement vorgesehen, welches ein kosten- und gewichtsintensives Zusatzteil darstellt.To connect the stiffening strut to the windshield cross member, a fastening device with a console element is usually provided, which represents a cost and weight-intensive additional part.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Befestigungsanordnung der eingangs genannten Art derart weiterzuentwickeln, dass eine besonders einfache Anbindung der Versteifungsstrebe an einen Karosserieträger, insbesondere den Windschutzscheiben-Querträger, sowie eine vorteilhafte Krafteinleitung von der Versteifungsstrebe in den Karosserieträger, Windschutzscheiben-Querträger, realisiert sind.It is therefore an object of the present invention, a fastening arrangement of the type mentioned in such a way that a particularly simple connection of the stiffening strut to a body support, in particular the windshield cross member, and an advantageous introduction of force from the stiffening strut in the body support, windshield cross member realizes are.
Diese Aufgabe wird durch eine Befestigungsanordnung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a fastening arrangement with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um eine Befestigungsanordnung der angegebenen Art zu schaffen, bei welcher eine besonders einfache Anbindung der Versteifungsstrebe an den Karosserieträger, vorzugsweise Windschutzscheiben-Querträger, sowie eine vorteilhafte Einleitung von Kräften über die Versteifungsstrebe in den Karosserieträger, vorzugsweise Windschutzscheiben-Querträger, geschaffen sind, ist es erfindungsgemäß vorgesehen, dass die Befestigungseinrichtung zumindest ein teilweise in dem Hohlquerschnitt angeordnetes Verstärkungselement des Karosserieträgers umfasst, welches wenigstens ein aus dem Hohlquerschnitt herausragendes Laschenelement aufweist, über das die Versteifungsstrebe an dem Karosserieträger befestigt ist.In order to provide a mounting arrangement of the specified type, in which a particularly simple connection of the stiffening strut to the body support, preferably windshield cross member, as well as an advantageous introduction of forces on the stiffening strut in the body support, preferably windshield cross member created, it is according to the invention provided that the fastening device comprises at least one partially arranged in the hollow cross-section reinforcing element of the body support, which has at least one protruding from the hollow cross-section tab member over which the stiffening strut is attached to the body support.
Das Verstärkungselement wird somit zum einen zum Verstärken des Karosserieträgers, vorzugsweise Windschutzscheiben-Querträgers, und zum anderen zum Anbinden der Versteifungsstrebe an den Karosserieträger genutzt, wodurch eine steife und belastbare Anbindung mit einer sehr hohen Betriebsfestigkeit geschaffen ist. Die sehr hohe Steifigkeit der Befestigungsanordnung führt auch zu einem besonders vorteilhaften Geräuschverhalten des Personenkraftwagens, welches üblicherweise auch als NVH-Verhalten (NVH – Noise Vibration Harshness) bezeichnet wird. Diese Doppelfunktion beziehungsweise Doppelnutzung des Verstärkungselements führt auch zu einer sehr leichten und platzsparenden Befestigung der Versteifungsstrebe an dem Karosserieträger, vorzugsweise Windschutzscheiben-Querträger, mit einer nur sehr geringen Teileanzahl.The reinforcing element is thus used on the one hand to reinforce the body support, preferably windshield cross member, and on the other to connect the stiffening strut to the body support, creating a rigid and resilient connection with a very high durability. The very high rigidity of the mounting arrangement also leads to a particularly advantageous noise behavior of the passenger car, which is also commonly referred to as NVH (Noise Vibration Harshness). This dual function or double use of the reinforcing element also leads to a very light and space-saving attachment of the stiffening strut to the body support, preferably windshield cross member, with only a very small number of parts.
