Description
Die Erfindung betrifft eine Strebenanordnung einer Kraftwagenkarosserie, insbesondere für einen offenen Kraftwagen, gemäß Oberbegriff des Anspruchs 1.The invention relates to a strut arrangement of a motor vehicle body, in particular for an open motor vehicle, according to the preamble of claim 1.

Diese Strebenanordnungen weisen weiteres Potential auf, die Kraftwagenkarosserie auszusteifen.These strut assemblies have further potential to stiffen the car body.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Strebenanordnung einer Kraftwagenkarosserie, insbesondere für einen offenen Kraftwagen, bereitzustellen, durch welche die Kraftwagenkarosserie weiter ausgesteift ist.It is therefore an object of the present invention to provide a strut assembly of a motor vehicle body, in particular for an open motor vehicle, through which the motor vehicle body is further stiffened.
Diese Aufgabe wird durch eine Strebenanordnung einer Kraftfahrzeugkarosserie, insbesondere für einen offenen Kraftwagen, 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 strut arrangement of a motor vehicle body, in particular for an open motor vehicle, with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Eine solche Strebenanordnung einer Kraftwagenkarosserie, insbesondere für einen offenen Kraftwagen, umfasst wenigstens zwei schräg zur Fahrzeuglängsrichtung und schräg zueinander verlaufende Streben zum Aussteifen der Kraftwagenkarosserie. Die Streben sind im Bereich eines Hauptbodens angeordnet und einenends an einem jeweiligen Seitenschweller der Kraftwagenkarosserie befestigt. Ausgehend von den jeweiligen Seitenschwellern verlaufen die Streben zu einem Mittenbereich der Kraftwagenkarosserie hin.Such a strut assembly of a motor vehicle body, in particular for an open motor vehicle, comprises at least two obliquely to the vehicle longitudinal direction and obliquely extending struts for bracing the motor vehicle body. The struts are arranged in the region of a main floor and attached at one end to a respective side skirts of the motor vehicle body. Starting from the respective side sills, the struts extend to a central region of the motor vehicle body.
Erfindungsgemäß ist vorgesehen, dass die Streben relativ zueinander überkreuzungsfrei verlaufen und andernends in dem Mittenbereich an einer den Streben gemeinsamen und zumindest im Wesentlichen in Fahrzeugquerrichtung verlaufenden Querstrebe der Strebenanordnung befestigt sind. Vorteilhafterweise ist die Querstrebe beidenends an den jeweiligen Seitenschwellern befestigt.According to the invention, it is provided that the struts run crossover-free relative to one another and, at the other end, are fastened in the middle region to a transverse strut of the strut arrangement which is common to the struts and extends at least substantially in the vehicle transverse direction. Advantageously, the crossbar is attached to both ends of the respective side sills.
Durch die erfindungsgemäße Strebenanordnung ist die Kraftwagenkarosserie besonders vorteilhaft ausgesteift und weist insbesondere eine sehr hohe Torsionssteifigkeit auf. Insbesondere infolge der Anordnung der Strebenanordnung im Bereich des Hauptbodens, wobei die erfindungsgemäße Strebenanordnung in Fahrzeughochrichtung beispielsweise unterhalb des Hauptbodens angeordnet ist, weist die Kraftwagenkarosserie insbesondere im Bereich der Fahrgastzelle der Kraftwagenkarosserie eine besonders hohe Torsionssteifigkeit auf. Hieraus resultiert ein besonders hoher Schwingungs- und Geräuschkomfort.The strut assembly according to the invention, the motor vehicle body is stiffened particularly advantageous and in particular has a very high torsional rigidity. In particular, as a result of the arrangement of the strut assembly in the region of the main floor, wherein the strut assembly according to the invention is arranged in the vehicle vertical direction, for example, below the main floor, the motor vehicle body, in particular in the passenger compartment of the motor vehicle body on a particularly high torsional stiffness. This results in a particularly high vibration and noise comfort.
Die erfindungsgemäße Strebenanordnung ist besonders bei einem offenen Kraftwagen, beispielsweise einem Cabriolet, einem Roadster oder dergleichen, vorteilhaft, da offene Kraftwagen in der Regel aufgrund eines nicht vorhandenen Daches bzw. eines zwischen einer Schließstellung und wenigstens einer Offenstellung bewegbaren Verdecks im Bereich der Fahrgastzelle eine relativ geringe Torsions- und Biegesteifigkeit aufweisen im Vergleich zu Kraftwagen mit einem festen Dach. Die erfindungsgemäße Strebenanordnung kann somit insbesondere einen offenen Kraftwagen aussteifen und ihm eine hohe Torsions- und Biegesteifigkeit verleihen. Dadurch lässt sich das sogenannte Cabrioschütteln vermeiden oder zumindest reduzieren.The strut assembly according to the invention is particularly advantageous in an open motor vehicle, for example a convertible, a roadster or the like, since open motor vehicles usually due to a non-existing roof or between a closed position and at least one open position movable hood in the passenger compartment a relative have low torsional and bending stiffness compared to cars with a fixed roof. The strut assembly according to the invention can thus in particular stiffen an open motor vehicle and give it a high torsional and bending stiffness. As a result, the so-called convertible shake can be avoided or at least reduced.
Ergänzend kann vorgesehen sein, dass die Seitenschweller besonders große Hohlquerschnitte aufweisen. Ergänzend oder alternativ kann vorgesehen sein, dass ein zumindest im Wesentlichen in Fahrzeuglängsrichtung verlaufender Tunnel des Hauptbodens durch wenigstens ein Überbrückungsteil zu einem geschlossenen Hohlquerschnitt ergänzt ist, wodurch ein geschlossenes Torsionsprofil gebildet ist.In addition, it can be provided that the side skirts have particularly large hollow cross-sections. Additionally or alternatively, it can be provided that a tunnel running at least substantially in the vehicle longitudinal direction of the main floor is supplemented by at least one bridging part to form a closed hollow cross-section, whereby a closed Torsionsprofil is formed.
Die erfindungsgemäße Strebenanordnung ermöglicht es dabei jedoch, auf eine solche Schließung des Tunnels durch das wenigstens eine Überbrückungsteil und/oder auf die Darstellung besonders großer Hohlquerschnitte der Seitenschweller zu verzichten oder diese gering zu halten bei gleichzeitiger Darstellung einer besonders hohen Biege- und Torsionsstefigkeit der Kraftwagenkarosserie. So kann mittels der erfindungsgemäßen Strebenanordnung das Gewicht der Kraftwagenkarosserie gering gehalten werden, wodurch der Kraftwagen mit einem nur geringen Kraftstoffverbrauch und nur geringen CO2-Emissionen angetrieben werden kann.However, the strut arrangement according to the invention makes it possible to dispense with such a closure of the tunnel by the at least one bridging part and / or the representation of particularly large hollow cross sections of the side skirts or to keep them low while displaying a particularly high bending and torsional rigidity of the car body. Thus, the weight of the motor vehicle body can be kept low by means of the strut assembly according to the invention, whereby the car can be driven with only low fuel consumption and low CO 2 emissions.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in der Figurenbeschreibung genannten und/oder in den Figuren alleine gezeigten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar, ohne den Rahmen der Erfindung zu verlassen.Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing.
