Abstract
Description
Die Erfindung bezieht sich auf ein Kraftfahrzeug mit einem seitliche Längsträger umfassenden Fahrzeugaufbau nach dem Oberbegriff des Anspruchs 1.The The invention relates to a motor vehicle with a lateral Longitudinal beam comprehensive vehicle body after the Preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es, einen Fahrzeugaufbau für ein Kraftfahrzeug mit Versteifungstreben zu schaffen, die eine stabile Lagerung eines Fahrschemels für eine Hinterradaufhängung gewährleisten.task The invention is a vehicle body for a motor vehicle with stiffening struts to create a stable mounting of a subframe ensure a rear suspension.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.These The object is solved by the features of claim 1. Further advantageous features include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass der in elastischen Lagern an seitlichen Längsträgern des Fahrzeugaufbaus gehaltene Fahrschemel für die Hinterradaufhängung lagestabil über Versteifungsstreben am Fahrzeugaufbau gehalten wird. Um dies zu erreichen, wird vorgeschlagen, dass jede Versteifungstrebe am äußeren freien Ende zwischen den seitlichen Längsträgern des Fahrzeugaufbaus und den Versteifungsstreben mit den elastischen Lagern für einen Fahrschemel verbunden ist, wobei die Versteifungsstreben sich diagonal von den seitlichen Längsträgern bis zu einem Tunnelschließblech in der Fahrzeuglängsmittenebene erstrecken und die Versteifungsstreben mit einem inneren Ende am Tunnelschließblech befestigt sind und eine vom äußeren freien Ende der Versteifungsstreben abgewinkelte Armstrebe jeweils mit den seitlichen Längsträgern im Abstand zum elastischen Lager verbunden sind. Hierdurch wird erreicht, dass eine mögliche quergerichtete Nachgiebigkeit der seitlichen Längsträger des Fahrzeugaufbaus die Funktion des Fahrschemels und somit der Hinterradaufhängung nicht beeinflusst wird.The consist with the invention mainly achieved advantages in that in elastic bearings on lateral side rails the vehicle body held subframe for the rear suspension kept stable on stiffening struts on the vehicle body becomes. To achieve this, it is suggested that any stiffening brace at the outer free end between the lateral side members the vehicle body and the stiffening struts with the elastic Bearings for a subframe is connected, with the stiffening struts diagonally from the side rails up to a tunnel strike plate in the vehicle longitudinal center plane extend and the stiffening struts with an inner end on Tunnel striking plate are fastened and one from the outside free End of the stiffening struts angled arm brace each with the lateral side members at a distance to the elastic Bearings are connected. This ensures that a possible transverse compliance of the lateral side members of the Vehicle structure, the function of the subframe and thus the rear suspension is not affected.
Ferner wird vorgeschlagen, dass die beiden diagonal ausgerichteten Versteifungsstreben im Bereich des Tunnelschließbleches sich überkreuzend angeordnet sind und ein Kreuzungspunkt der Versteifungsstreben in der Fahrzeuglängsmittenebene und in einem Längsabstand zum Tunnelschließblech angeordnet ist. Die Versteifungsstreben sind im Kreuzungspunkt fest bzw. durch eine Schweißung miteinander verbunden.Further It is suggested that the two diagonally oriented stiffening struts arranged in the region of the tunnel strike plate crossing each other are and a crossing point of the stiffening struts in the vehicle longitudinal center plane and at a longitudinal distance to the tunnel strike plate is arranged. The stiffening struts are fixed in the crossing point or connected by a weld.
Zur weiteren Versteifung bzw. Fixierung des Lagers für den Fahrschemel ist vorgesehen, dass die von den diagonal ausgerichteten Versteifungsstreben abgewinkelten Armstreben mit dem elastischen Lager fest verbunden sind und vom elastischen Lager schräg nach außen zum seitlichen Längsträger verlaufend angeordnet sind und die Befestigung am Längsträger mit einem Abstand in Querrichtung und Längsrichtung erfolgt. Durch diese Anordnung der Versteifungsstreben mit den Armstreben wird eine optimale Abstützung des elastischen Lagers in unterschiedlichen Richtungen und zwar in Quer- und in Längsrichtung erzielt. Hierzu sind die Versteifungsstreben zu den Armstreben unter einem Winkel von 90° angeordnet. Des Weiteren sind die Versteifungsstreben zur Fahrzeuglängsmittenebene des Fahrzeugaufbaus unter einem Winkel von 45° angeordnet.to further stiffening or fixation of the bearing for the Subframe is provided that of the diagonally oriented Stiffening struts angled arm struts with the elastic bearing are firmly connected and from the elastic bearing obliquely running outside to the side rail are arranged and the attachment to the side rail with a distance in the transverse direction and longitudinal direction. By this arrangement, the stiffening struts with the arm struts will provide optimal support of the elastic bearing in different directions in the transverse and in the longitudinal direction achieved. For this purpose, the stiffening struts to the arm struts are below arranged at an angle of 90 °. Furthermore, the Stiffening struts to the vehicle longitudinal center plane of the vehicle body arranged at an angle of 45 °.
Insbesondere wird vorgeschlagen, dass der elastisch auf den Lagern gehaltene Fahrschemel über eine Schraube mit den seitlichen Längsträgern des Fahrzeugaufbaus abgestützt verbunden ist, auf der das äußere Ende der Versteifungsstrebe und ein Ende der abgewinkelten Armstrebe befestigt gehalten wird. Die Versteifungsstreben und die Armstreben sind ortsfest am Tunnelschließblech und an seitlichen Längsträgern derart abgestützt, dass ein sogenanntes Stützfachwerk in einer horizontalen Ebene des Fahrzeugbodens für die seitlichen Längsträger gebildet wird und die elastischen Lager eine definierte Kennung zur Aufnahme des Fahrschemels und der von diesem aufgenommenen Hinterradaufhängung aufweisen. Es wird durch die Strebenanordnung erreicht, dass der Fahrschemel trotz der Elastizität der Lager – was für eine Rollgeräuschisolierung erforderlich ist, aber fahrdynamisch nicht unbedingt von Vorteil ist – eine stabile Lage aufweist.Especially It is suggested that the elastically held on the bearings Subframe via a screw with the lateral side members of the Vehicle body is connected supported on the outside End of the stiffening brace and one end of the angled arm brace is held attached. The stiffening struts and the arm struts are stationary on the tunnel strike plate and on the side rails supported so that a so-called support framework in a horizontal plane of the vehicle floor for the lateral side member is formed and the elastic Bearings a defined identifier for receiving the subframe and have the recorded by this rear suspension. It is achieved by the strut arrangement that the subframe despite the elasticity of the bearings - what for a rolling noise insulation is required, but driving dynamics not necessarily beneficial - has a stable position.
