Abstract
Tragstruktur (10) für eine selbsttragende Längs- und Querträger (15, 15', 16, 16') sowie Schweller (18, 18') umfassende Kraftfahrzeugkarosserie mit hinteren Radhäusern (11), wobei jedes Radhaus (11) von einem etwa U-förmig gebogenen Radhausbügel (13, 13') großer Breite (b) gebildet ist, deren Querschnitt aus rechteckförmigen Hohlprofilen (12, 12', 17) geformt ist, und dessen Schenkelenden (27, 28) an einem Karosserieträger (15, 16, 22) mit der Tragstruktur (10) verbunden sind und deren Scheitelbereiche jeweils eine Lagerfläche (25) für einen Dämpfer (24) bilden, und die Schweller (18, 18') gegenüber den Längsträgern (16, 16') einen unterschiedlichen Bodenabstand aufweisen.Support structure (10) for a self-supporting longitudinal and transverse beams (15, 15 ', 16, 16') and sills (18, 18 ') comprising a motor vehicle body with rear wheel arches (11), each wheel house (11) from an approximately U shaped curved wheel arch (13, 13 ') of large width (b) is formed, whose cross section of rectangular hollow sections (12, 12', 17) is formed, and whose leg ends (27, 28) on a body support (15, 16, 22 ) are connected to the support structure (10) and their apex areas each form a bearing surface (25) for a damper (24), and the sills (18, 18 ') opposite the side rails (16, 16') have a different ground clearance.
Description
Die Erfindung betrifft eine Tragstruktur für eine selbsttragende, Längs- und Querträger sowie Schweller umfassende Kraftfahrzeugkarosserie mit im Heckbereich liegenden Radhäusern.The The invention relates to a support structure for a self-supporting, longitudinal and crossbeam as well as sill comprehensive vehicle body with in the rear area lying wheel arches.
Bekanntlich
bilden die über
Querträger
miteinander verbundenen Längsträger des
rückwärtigen Bereichs
einer Fahrzeugkarosserie eine im Heckbereich liegende Radhäuser umfassende
Tragstruktur, die bei einer Fahrzeugkollision in der Lage ist, ausreichend
Verformungsenergie aufzunehmen; vgl.
Solche aus geformten und mittels Schweißstellen miteinander verbundenen Blechteilen gebildeten Tragstrukturen sind aufwendig in der Herstellung. Infolge des Raumbedarfs der Radhäuser und der unterschiedlichen Bodenabstände von Längsträgern und Schwellern haben diese Blechteile kompliziert gebogene Raumformen und Abkröpfungen und sind zur Versteifung zusätzliche Versteifungselemente nötig, um bei Kollisionen ein Zusammenbrechen des betroffenen Radhauses zu vermeiden, was auch zur Beschädigung des dort befindlichen Tankbereiches führt.Such made of molded and connected by welds Sheet metal parts formed support structures are expensive to manufacture. As a result the space requirements of the wheel arches and the different ground clearances of side rails and sills have these Sheet metal parts complicated curved room shapes and offsets and are additional to stiffening Stiffening elements necessary, at collisions a collapse of the affected wheel arch to avoid what also to damage the tank area located there leads.

Hier setzt nun die Erfindung ein, der die Aufgabe zugrunde liegt, die Ausbildung einer solchen Tragstruktur zu vereinfachen bei gleichzeitiger Erhöhung der von der Tragstruktur aufzunehmenden Verformungsenergie.Here Now uses the invention, which is the object of the Training of such a support structure to simplify while increase the deformation energy to be absorbed by the support structure.
Diese Aufgabe ist gemäß der Erfindung durch die Merkmale des Patentanspruches 1 gelöst.These Task is in accordance with the invention by the features of claim 1 solved.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further Features of the invention will become apparent from the dependent claims.
Die erfindungsgemäße Ausbildung der Tragstruktur mit Hilfe von an einem Karosserieträger, z. B. an über Querträger miteinander verbundenen Längsträgern befestigten, aus Hohlprofilen geformten Radhausbügeln, die im oberen Bereich – vorzugsweise im Falle einer Limousine – über eine Hutablage und im unteren Bereich über einen Querträger miteinander verbunden sind, wird eine verwindungssteife Konstruktion erreicht, die eine optimale Einleitung der Kräfte in die Karosserie in vertikaler Richtung ermöglicht, und zwar mit Hilfe einer weitest gehend einteiligen Lösung, also unter Vermeidung einer Vielzahl von aufwendig geformten Blechteilen unter gleichzeitiger integraler Anbindung von Dämpfern für die Radachsen. Dies führt auf überraschend einfache Weise zu einer signifikanten Kosteneinsparung bei verbesserter Crashfestigkeit.The inventive training the support structure by means of a body support, z. B. to about crossbeam fixed to interconnected side members, formed from hollow profiles wheel arch, in the upper area - preferably in the case of a limousine - over one Parcel shelf and in the lower area via a cross member with each other connected, a warp-resistant construction is achieved, the optimal introduction of forces into the body in vertical Direction allows and with the help of a largely one-piece solution, so while avoiding a variety of elaborately shaped sheet metal parts with simultaneous integral connection of dampers for the wheel axles. This leads to surprising easy way to a significant cost savings with improved Crash resistance.
