Abstract
Ein Vorderwagen eines Kraftfahrzeugs ist mit einer versteifenden Strebenanordnung versehen, welche aus A-förmig angeordneten Versteifungsstreben sowie vorderen Versteifungsstreben sowie einer Domstrebe besteht. Insgesamt sind die Versteifungsstreben mit der Karosserie sowie mit den Federbeindomen fest verbunden, so dass sich zwei Schubfelder bilden.A front end of a motor vehicle is provided with a stiffening strut assembly, which consists of A-shaped stiffening struts and front stiffening struts and a strut brace. Overall, the stiffening struts are firmly connected to the body and the strut dome, so that form two shear fields.
Description
Die Erfindung bezieht sich auf eine Karosseriestruktur für ein Kraftfahrzeug mit einer versteifenden Strebenanordnung nach dem Oberbegriff des Anspruchs 1. The invention relates to a body structure for a motor vehicle with a stiffening strut assembly according to the preamble of
Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Vorderwagen eines Kraftfahrzeugs mit einer Strebenanordnung zu schaffen, die eine Versteifung des gesamten Vorderwagens von der Stirnwand bis zu einem vorderen Querträger der Fahrzeugkarosserie gewährleistet. The invention has for its object to provide a front end of a motor vehicle with a strut assembly, which ensures stiffening of the entire front end of the front wall to a front cross member of the vehicle body.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche. This object is achieved by the features of
Die Erfindung beruht im Wesentlichen darauf, eine Vorderwagenstruktur eines Kraftfahrzeugs durch eine Kombination von Versteifungsstreben insgesamt zu verstärken, was nach der Erfindung erreicht wird, indem eine Strebenanordnung horizontal ausgerichtete hintere – in Bezug auf die Fahrtrichtung gesehen – A-förmig angestellte Versteifungsstreben sowie eine quer verlaufende Domstrebe umfasst, an der sich schräg nach vorn in Fahrzeuglängsrichtung erstreckende horizontal verlaufende vordere Versteifungsstreben anschließen und die Versteifungsstreben eine geschlossene Ringstruktur bilden. The invention is essentially based on a total of reinforcing a front end structure of a motor vehicle by a combination of stiffening struts, which is achieved according to the invention by a strut assembly horizontally oriented rear - seen in relation to the direction of travel - A-stiffened struts and a transverse Domstrebe comprises, at the obliquely forward in the vehicle longitudinal direction extending horizontally extending front reinforcing struts connect and form the stiffening struts a closed ring structure.
Insbesondere ist nach der Erfindung vorgesehen, dass die hinteren A-förmigen Versteifungsstreben in Fahrzeuglängsrichtung divergierend ausgeführt sind und die vorderen freien Enden dieser Versteifungsstreben jeweils mit einem Federbeindom und die hierzu abgekehrten hinteren Enden der Versteifungsstreben zusammengeführt mit einem Stirnwandträger oder einem Windlauf der Karosserie verbunden sind. Die Domstrebe ist den A-förmigen Versteifungsstreben vorgelagert angeordnet und die beiden freien Enden sind jeweils mit einem Federbeindom verbunden. In particular, it is provided according to the invention that the rear A-shaped stiffening struts are designed to diverge in the vehicle longitudinal direction and the front free ends of these stiffening struts are each connected to a strut tower and the rear ends facing away from the stiffening struts combined with an end wall support or a cowl of the body. The strut brace is placed in front of the A-shaped stiffening struts and the two free ends are each connected to a strut tower.
Ferner ist nach der Erfindung vorgesehen, dass die schräg nach vorn in Fahrzeuglängsrichtung zulaufenden Versteifungsstreben mit hinteren freien Enden – in Bezug auf die Fahrtrichtung gesehen – jeweils am Federbeindom verbunden sind und die vorderen freien Enden an einem Querträgerelement des Vorderwagens befestigt gehalten sind. It is also provided according to the invention that the obliquely forward converging in the vehicle longitudinal direction stiffening struts with rear free ends - as seen in relation to the direction of travel - are each connected to the strut tower and the front free ends are held fixed to a cross member of the front end.
Die Verbindung der A-förmigen Versteifungsstreben sowie der Domstrebe und der weiteren vorderen Versteifungsstreben mit dem fest in die Fahrzeugkarosserie integrierten Federbeindomen, ergibt festigkeitsmäßig eine stabile Anbindung und somit eine starre Verbindung der Strebenanordnung zwischen den Federbeindomen des Kraftfahrzeugs. The compound of the A-shaped stiffening struts and the strut brace and the other front stiffening struts with the firmly integrated into the vehicle body Federbeindomen, strength results in a stable connection and thus a rigid connection of the strut assembly between the Federbeindomen of the motor vehicle.
Insbesondere ist nach der Erfindung vorgesehen, dass die A-förmigen Verbindungsstreben über mindesten zwei Befestigungen mit den Federbeindomen verbunden und welche in einer Konsole angeordnet sind, die über Schrauben im Federbeindom befestigbar gehalten werden. Des Weiteren sind die freien Enden der schräg nach vorne zulaufenden Versteifungsstreben über abstehende Laschenelemente sowie endseitig am Querträgerelement oder der Karosserie verbunden. Durch diese Mehrfachanbindung der Versteifungsstreben wird ein Auslenken dieser Streben verhindert und ein gemeinsamer stabiler Verbund erreicht. In particular, it is provided according to the invention that the A-shaped connecting struts connected via at least two fasteners with the Federbeindomen and which are arranged in a console, which are held fastened by screws in Federbeindom. Furthermore, the free ends of the obliquely forward tapered reinforcing struts are connected via protruding tab members and the end of the cross member or the body. Through this multiple connection of the stiffening struts a deflection of these struts is prevented and achieved a common stable bond.
Durch die A-förmig angeordneten hinteren Versteifungsstreben wird ein sogenanntes erstes Schubfeld und durch die weiteren vorderen Versteifungsstreben wird mit der Domstrebe ein sogenanntes zweites Schubfeld gebildet. Die Schubfelder erstrecken sich vorzugsweise in einer etwa horizontalen Ebene und sind in Fahrzeuglängs- und Querrichtung angeordnet. By the A-shaped rear stiffening struts is a so-called first thrust field and the other front stiffening struts a so-called second thrust field is formed with the strut. The shear fields preferably extend in an approximately horizontal plane and are arranged in the vehicle longitudinal and transverse directions.
Durch die Anbindung der Versteifungsstreben gemeinsam am Federbeindom sowie an der Fahrzeugkarosserie bilden diese Versteifungsstreben nach der Erfindung eine geschlossene Ringstruktur, welche einen Festigkeitsverbund im Vorderwagen bildet und der Vorderwagen zusätzlich ausgesteift wird. By connecting the stiffening struts together on Federbeindom and on the vehicle body, these stiffening struts according to the invention form a closed ring structure, which forms a strength composite in the front end and the front end is additionally stiffened.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben. An embodiment of the invention is illustrated in the drawings and will be described in more detail below.
