Description
Die Erfindung betrifft eine Trägerstruktur im Vorderwagen einer Fahrzeugkarosserie nach dem Oberbegriff des Anspruchs 1.The The invention relates to a support structure in the front of a vehicle body according to the preamble of Claim 1.
Eine bekannte Trägerstruktur im Vorderwagen einer Kraftfahrzeugkarosserie (ATZ/MTZ – Sonderausgabe Porsche 911 Carrera 1998, Seite 57, Bild 6) umfaßt einen unteren Frontscheiben-Querträger und einen linken und rechten Federbeindom, wobei der linke Federbeindom mit einer linken Strebe und der rechte Federbeindom mit einer rechten Strebe mit dem unteren Frontscheiben-Querträger verbunden sind.A known carrier structure in the front of a motor vehicle body (ATZ / MTZ - special issue Porsche 911 Carrera 1998, page 57, Figure 6) comprises a lower windscreen cross member and a left and right Federbeindom, wherein the left Federbeindom with a left strut and the right strut dome with a right Strut connected to the lower windscreen cross member.
Der jeweilige Anschlußpunkt der rechten Strebe und der linken Strebe am unteren Frontscheiben-Querträger sind gegenüber der Quermitte beabstandet, wobei dieser Abstand etwa 1/3 bis 1/4 der gesamten Querlänge des unteren Frontscheiben-Querträgers beträgt.Of the respective connection point the right strut and the left strut on the lower windscreen cross member are across from the transverse center, this distance about 1/3 to 1/4 the entire transverse length of the lower windscreen cross member is.
Eine solche bekannte Strebenanordnung kann die Torsionssteifigkeit, insbesondere die dynamische Torsionssteifigkeit der Fahrzeugkarosserie erhöhen.A Such known strut arrangement can torsional rigidity, in particular increase the dynamic torsional stiffness of the vehicle body.

Aufgabe der Erfindung ist es, eine gattungsgemäße Trägerstruktur im Vorderwagen einer Fahrzeugkarosserie so weiterzubilden, daß die Torsionssteifigkeit, insbesondere die dynamische Torionssteifigkeit einer Fahrzeugkarosserie weiter erhöhbar und optimierbar ist.task The invention is a generic support structure in the front a vehicle body so that the torsional stiffness, in particular the dynamic torsional stiffness of a vehicle body further increase and is optimizable.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved with the features of claim 1.
Gemäß Anspruch 1 sind die rechte Strebe und die linke Strebe an einem gemeinsamen Anschlußpunkt in der Quermitte des unteren Frontscheiben-Querträgers verbunden.According to claim 1, the right strut and the left strut are at a common connection point connected in the transverse center of the lower windscreen cross member.
Berechnungen und Versuche haben ergeben, daß eine solche Struktur mit einem gemeinsamen Anschlußpunkt der beiden Streben in der Quermitte des unteren Frontscheiben-Querträgers die Torsionssteifigkeit, insbesondere die dynamische Torsionssteifigkeit überraschend stark erhöht gegenüber Anordnungen, bei denen die Anschlußpunkte der beiden Streben am Frontscheiben-Querträger beabstandet sind. Zudem ist dies eine einfache Maßnahme, die auch eine vereinfachte und kostengünstigere Anschlußtechnik an nur einem Anschlußpunkt ermöglicht.calculations and experiments have shown that a such structure with a common connection point of the two struts in the transverse center of the lower windscreen cross member the torsional stiffness, in particular the dynamic torsional stiffness is surprisingly greatly increased compared to arrangements, where the connection points of two struts are spaced on the windscreen cross member. moreover is this a simple measure which also has a simplified and less expensive connection technology allows only one connection point.
In einer Ausführungsform entsprechend dem Stand der Technik sind die beiden Streben jeweils unmittelbar an ihrem zugeordneten Federbeindom angeschlossen.In an embodiment according to the prior art, the two struts are respectively connected directly to its associated strut tower.
In einer alternativen Anordnung sind die linke Strebe und die rechte Strebe nur mittelbar mit den Federbeindomen verbunden, indem sie jeweils im Bereich der Federbeindome an einem diese verbindenden Federbeindom-Querträger angeschlossen sind. Eine solche Anordnung kann vorteilhaft bei der Optimierung der Steifigkeiten und hinsichtlich eines vorgegebenen Platzangebots sein.In an alternative arrangement are the left strut and the right one Strive only indirectly with the Federbeindomen connected by in each case in the region of the spring legs at a connecting these Strut tower cross member are connected. Such an arrangement may be advantageous in optimization the stiffness and in terms of a given space be.
Im Bereich solcher Streben ist üblicherweise bei Fahrzeugkarosserien ein Wasserkasten angeordnet, so daß ggf. die Streben in einem Wasserkasten angeordnet sein können. Dabei ist es zweckmäßig, die Streben im Bereich der vorderen Wasserkastenwand anzubringen oder die Streben als Teil einer solchen vorderen Wasserkastenwand auszubilden.in the Range of such struts is usually at Vehicle bodies arranged a water tank, so that possibly the Struts can be arranged in a water tank. It is expedient, the Struts to install in the area of the front water box wall or to form the struts as part of such a front water box wall.
In einer konkreten Vorderwagenausführung ist in einem Abstand zum unteren Frontscheiben-Querträger ein damit vorzugsweise durch ein Querblech verbundener, etwa auf gleicher Höhe sowie zur Heckseite hin versetzter oberer Spritzwand-Querträger angebracht. An den Spritzwand-Querträger schließt sich nach unten eine Spritzwand mit Öffnungen für Einbaugeräte an. Besonders bei großen Öffnungen, beispielsweise für ein Klimagerät, ist die Torsionssteifigkeit beeinträchtigt und wird durch die erfindungsgemäße Strebenanordnung erheblich verbessert.In a concrete front end model is at a distance to the lower windscreen cross member thus preferably connected by a cross-plate, about the same Height as well attached to the rear side upper bulkhead cross member attached. To the bulkhead cross member includes down to a bulkhead with openings for built-in appliances. Especially with large openings, for example an air conditioner, the torsional stiffness is impaired and is caused by the strut arrangement according to the invention significantly improved.
Anhand einer Zeichnung wird die Erfindung näher erläutert.Based a drawing, the invention is explained in detail.
