Die vorliegende Erfindung beschäftigt sich mit dem Problem, eine verbesserte oder zumindest eine andere Ausführungsform für ein gattungsgemäßes Kraftfahrzeug anzugeben, um die dynamische Struktursteifigkeit, insbesondere bei einem Cabrioletfahrzeug, weiter zu erhöhen.The The present invention addresses the problem of an improved or at least another embodiment for a generic motor vehicle to indicate the dynamic structural rigidity, especially at a convertible vehicle to further increase.
Die Erfindung löst diese Aufgabe durch den Gegenstand des unabhängigen Anspruchs 1.The Invention solves this problem by the subject of the independent Claim 1.
Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.Further advantageous features include the subclaims.
Das erfindungsgemäße Kraftfahrzeug ist dadurch gekennzeichnet, dass zwischen den Diagonalstreben zumindest ein mit den Diagonalstreben und/oder dem Hinterachsquerträger verbundenes, im Wesentlichen flächiges, Schubfeld angeordnet ist. Die Anordnung eines Schubfeldes in diesem Bereich ist insofern vorteilhaft, als dass damit sowohl die Fahrdynamik als auch die Torsionssteifigkeit des Kraftfahrzeuges verbessert werden können.The Motor vehicle according to the invention is characterized that between the diagonal struts at least one with the diagonal struts and / or the Hinterachsquerträger connected, essentially flat, Thrust field is arranged. The arrangement of a shear field in this Range is advantageous in that as well as the driving dynamics as well as the torsional stiffness of the motor vehicle improved can be.
Beispielsweise ist das Schubfeld aus Aluminiumblech oder einem anderen bevorzugt leichten, korrosionsbeständigen Material hergestellt.For example the thrust field of aluminum sheet or another is preferred lightweight, corrosion-resistant material.
Die Anbindung des Schubfeldes an die Diagonalstreben und/oder den Hinterachsquerträger kann mittelbar, beispielsweise über zusätzliche Halte- oder Befestigungselemente welche am Schubfeld und/oder den Diagonalstreben und/oder dem Hinterachsquerträger vorgesehen sind, oder unmittelbar an den Diagonalstreben und/oder dem Hinterachsquerträger erfolgen.The Connection of the thrust field to the diagonal struts and / or the Hinterachsquerträger can indirectly, for example via additional holding or fasteners which on the push panel and / or the diagonal struts and / or the Hinterachsquerträger are provided, or directly to the diagonal struts and / or the Hinterachsquerträger respectively.
Beispielsweise kann das Schubfeld lösbar mit den Diagonalstreben und/oder dem Hinterachsquerträger verbunden, insbesondere verschraubt sein. Beispielsweise kann das Schubfeld dazu mit mehreren Ausnehmungen versehen sein, durch die die Befestigungsmittel, insbesondere Schrauben, gesteckt werden können. In den Diagonalstreben bzw. dem Hinterachsquerträger können dementsprechend Gewindelöcher oder andere Verbindungspartner angeordnet sein. Die Anbindung kann aber auch, wie bereits beschrieben, über zusätzliche Halte- oder Befestigungselemente realisiert werden.For example can the shear field releasably with the diagonal struts and / or the Hinterachsquerträger connected, in particular screwed. For example, the thrust field can do this with multiple recesses be provided, through which the fastening means, in particular screws, can be plugged. In the diagonal braces or the Hinterachsquerträger accordingly threaded holes or other connection partners. The connection can but also, as already described, about additional Holding or fastening elements can be realized.
Es ist ferner denkbar, dass das Schubfeld unlösbar mit den Diagonalstreben und/oder dem Hinterachsquerträger verbunden, insbesondere verschweißt ist. Ferner ist denkbar, dass das Schubfeld verschraubt und verschweißt wird bzw. bestimmte Bereiche verschraubt und andere Bereiche verschweißt werden.It is also conceivable that the shear field insoluble with the Diagonal struts and / or the Hinterachsquerträger connected, in particular welded. It is also conceivable that the thrust field is bolted and welded or certain areas bolted and other areas are welded.
Besonders die Variante des Anschraubens des Schubfeldes bietet die Möglichkeit einer nachträglichen Montage des Schubfeldes an den bereits an der Karosserie befestigten Diagonalstreben und/oder Hinterachsquerträger (die beispielsweise Bauteile einer Aussteifungsstruktur darstellen können), wodurch auch eine Wartung bzw. im Reparaturfall ein Austausch des Schubfeldes deutlich einfacher realisiert werden kann.Especially the variant of screwing the shear field offers the possibility a subsequent installation of the thrust field to the already the body mounted diagonal braces and / or rear axle crossmember (For example, represent the components of a stiffening structure can), whereby a maintenance or in case of repair an exchange of the thrust field can be realized much easier can.
Eine Ausführungsform sieht vor, dass sich das zumindest eine Schubfeld entgegen der Fahrtrichtung gesehen nach hinten trapezartig verjüngen kann. Sind mehrere Schubfelder hintereinander vorgesehen, verjüngen sich bevorzugt alle Schubfelder trapezartig nach hinten bzw. entsprechen in ihrem Konturverlauf dem V-förmigen Verlauf der Diagonalstreben.A Embodiment provides that the at least one Schubfeld seen against the direction of travel to the rear trapezoidal can rejuvenate. Are several shearfields behind each other provided, preferably all shear fields tapered trapezoidal to the rear or correspond in their contour to the V-shaped Course of the diagonal struts.
Eine bevorzugte Ausführungsform sieht vor, dass das Schubfeld zumindest bereichsweise mit einer Präge- und/oder Rippenstruktur versehen sein kann. Bezugnehmend auf die mechanische Versteifung kann das Schubfeld daher beispielsweise mit beliebig verlaufenden Rippen oder Sicken, die beispielsweise der zusätzlichen Versteifung dienen können, versehen sein. In den geprägten Bereichen können beispielsweise die Befestigungselemente, insbesondere Schrauben oder dergleichen, zur Anlage kommen.A preferred embodiment provides that the shear field can be provided at least in regions with an embossing and / or rib structure. With reference to the mechanical stiffening, the thrust field can therefore, for example, with be arbitrarily extending ribs or beads, which may serve, for example, the additional reinforcement provided. In the embossed areas, for example, the fastening elements, in particular screws or the like, come to rest.
Bevorzugt weist das Schubfeld im Hinblick auf die Fahrzeugstruktur und/oder die Fahrdynamik somit versteifende und/oder luftleitende und/oder akustisch verbessernde Eigenschaften auf.Prefers has the thrust field with regard to the vehicle structure and / or the driving dynamics thus stiffening and / or air-conducting and / or acoustic improving properties.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung beschrieben ist. Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further Advantages, features and details of the invention will become apparent the description below, with reference to the drawings an embodiment of the invention is described. It can in the claims and in the Description mentioned features individually for each itself or in any combination essential to the invention.
