Abstract
Trägerstruktur für Aufbauten von Kraftfahrzeugen, insbesondere Personenkraftwagen, welche Trägerstruktur wenigstens zwei im Winkel zueinander angeordnete rohrförmige Träger aufweist, wovon wenigstens ein Träger – im Querschnitt gesehen – mit unterschiedlichen Wandstärken versehen ist, wobei vorzugsweise ein erster Träger (2, 8, 9) und ein zweiter Träger (3, 10, 11) der Trägerstruktur (1, 12, 13) mit unterschiedlichen Wandstärken (Ws1, Ws2, Ws3, Ws4, Ws5, Ws6, Ws7, Ws8) ausgeführt sind, dadurch gekennzeichnet, dass der rohrförmige Träger einen kreis- oder ellipsenförmigen Querschnitt aufweist und zumindest der erste Träger (2, 8, 9) in einem gemeinsamen Verbindungsbereich des ersten Trägers (2, 8, 9) und des zweiten Trägers (3, 10, 11) eine größere Wandstärke (Ws1, Ws3, Ws5) aufweist als in einem übrigen Umfangsbereich.Carrier structure for structures of motor vehicles, especially passenger cars, which support structure has at least two mutually angularly arranged tubular support, of which at least one support - seen in cross-section - is provided with different wall thicknesses, preferably a first carrier (2, 8, 9) and a second support (3, 10, 11) of the support structure (1, 12, 13) with different wall thicknesses (Ws1, Ws2, Ws3, Ws4, Ws5, Ws6, Ws7, Ws8) are executed, characterized in that the tubular support is a circle or elliptical cross-section and at least the first carrier (2, 8, 9) in a common connection region of the first carrier (2, 8, 9) and the second carrier (3, 10, 11) has a greater wall thickness (Ws1, Ws3, Ws5) than in a remaining peripheral area.
Description
Die Erfindung bezieht sich auf eine Trägerstruktur für Aufbauten von Kraftfahrzeugen, insbesondere Personenkraftwagen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a support structure for structures of motor vehicles, in particular passenger cars, according to the preamble of

Aufgabe der Erfindung ist es, eine Trägerstruktur für Aufbauten von Kraftfahrzeugen zu schaffen, die bei vorteilhaftem Gewicht hohe Belastungen aufnimmt und mit vertretbarem Aufwand herstellbar ist.The object of the invention is to provide a support structure for structures of motor vehicles, which receives high loads at an advantageous weight and can be produced with reasonable effort.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is solved by the features of
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß die Trägerstruktur einerseits zur Gewichtsoptimierung des Aufbaus beiträgt und andererseits aufgrund der besonderen Gestaltung der Träger, die aus Stahl oder Leichtmetall bestehen können, für die Aufnahme hoher Kräfte und Momente geeignet ist. Dabei läßt sich besagte Trägerstruktur ohne weiteres in Aufbaukonzepte mit bekannten konstruktiven Maßnahmen integrieren. Für die Herstellung der Träger können sowohl Strangpress- wie auch Innenhochdrucktechnologien eingesetzt werden. Denkbar ist aber auch die Träger aus mehreren schalenartigen Teilen zusammenzusetzen, wobei diese Teile durch Schweißen miteinander verbunden sind.The advantages achieved by the invention are to be seen in the fact that the support structure on the one hand contributes to the weight optimization of the structure and on the other hand due to the special design of the carrier, which may consist of steel or light metal, is suitable for absorbing high forces and moments. In this case, said support structure can be readily integrated into design concepts with known design measures. Both extruded and hydroforming technologies can be used to produce the beams. It is also conceivable to assemble the carriers from a plurality of shell-like parts, these parts being connected to one another by welding.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt, die nachstehend näher beschrieben sind.In the drawings, embodiments of the invention are shown, which are described in more detail below.
