Description
Die Erfindung betrifft eine Fahrzeugkarosserie gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a vehicle body according to the Preamble of claim 1.
Aus dem DE-Gbm 83 26 978 ist bereits ein Gerippe für einen Wagenkasten bekannt, bei dem Profilstäbe über vor stehende oder versenkte Eckverbindungsstücke miteinander verbunden sind. Diese Eckverbindungsstücke sind in nach außen hin offenen Nuten der Profile eingesetzt und über eine Klemm- und Schraubverbindung an den Profilen befe stigt. Durch die Ausbildung von nach außen hin offenen Nuten wird die Steifigkeit in bezug zu einem geschlosse nen Profil verringert. Ferner verlaufen die Rippen und Stege der Profile über die gesamte Länge der Profile. Aus diesem Grund baut die bekannte Konstruktion relativ schwer. Ferner sind Versteifungen nur in Verpressungs richtung möglich.DE-Gbm 83 26 978 is already a skeleton for a car body known in the profile bars above standing or recessed corner connectors with each other are connected. These corner connectors are in after Grooves of the profiles open on the outside and over a clamp and screw connection on the profiles increases. By training from the outside Grooves will make the stiffness relative to a closed one reduced profile. Furthermore, the ribs and Crossbars of the profiles over the entire length of the profiles. Out for this reason, the known construction builds relatively heavy. Furthermore, stiffeners are only in compression direction possible.
Aufgabe der Erfindung ist es, eine Fahrzeugkarosserie zu schaffen, die bei einem geringen Gewicht eine hohe Stei figkeit aufweist. The object of the invention is to provide a vehicle body create a high weight with a low weight ability.

Durch die Verwendung geschlossener oder offener Strang preßprofile, die zu einem geschlossenen Profil miteinan der verbunden werden und bei denen weitestgehend auf die Ausbildung von Nuten an der Oberfläche verzichtet ist, sind kleine Querschnitte bei hoher Steifigkeit erreich bar. Der Einsatz von Kernen in den Knotenbereichen, die innerhalb der Strangpreßprofile angeordnet sind, ermög licht eine gezielte Versteifung an den Verbindungsstellen mehrerer Profile. Einzelne Kerne können einstückig zu ei nem Knotenelement miteinander verbunden sein, so daß sich eine hohe Formsteifigkeit ergibt. Dadurch sind höhere Kräfte übertragbar. Auch können die Kerne neben einer örtlichen Versteifung als Mantel- oder Steckverbindungen dienen. Vorteilhaft ist der Einsatz von Kernen an Kraft einleitungsstellen, wie insbesondere an den Befestigungs stellen von Türschanieren. Durch die Variationsmöglich keiten in bezug auf die Lage und Geometrie des Kerns bzw. der Kerne ist eine optimale Anpassung des Kerns an die auftretenden Belastungen möglich. Die Befestigung des Kerns innerhalb des Strangpreßprofils kann durch Preß sitz, Verkleben, Verschweißen, Verschrauben, Vernieten oder Kaltpreßschweißen erfolgen. Ferner können zu Repara turzwecken die Kerne auch lösbar mit den Strangpreßprofi len verbunden sein.By using closed or open strand pressed profiles that together to form a closed profile who are connected and who are largely based on the Formation of grooves on the surface is dispensed with, small cross sections with high rigidity are achieved bar. The use of cores in the node areas that are arranged within the extruded profiles, made possible targeted reinforcement at the connection points multiple profiles. Individual cores can be made in one piece Nem be connected to each other so that results in a high degree of dimensional stability. This makes higher ones Forces transferable. The cores can also be placed next to one local stiffening as jacket or plug connections serve. The use of cores to power is advantageous introduction points, such as in particular on the attachment provide door hinges. Because of the possible variations with regard to the position and geometry of the core or The core is an optimal adaptation of the core to the occurring loads possible. The attachment of the Core within the extruded profile can by pressing fit, glue, weld, screw, rivet or cold pressure welding. You can also go to Repara the cores can also be detached with the extrusion professional len be connected.
