Abstract
Ein solcher Strukturträger als Karosseriebauteil von Personen- oder Kleinlastkraftwagen, insbesondere für Frontendmodule solcher Kraftwagen, besteht aus einem Hohlprofil aus einem steifen Werkstoff, das entlang einer seiner Längsseiten eine von seinen beidseitig längslaufenden Randbereichen begrenzte Öffnung hat und in dem im Spritzgießverfahren eingebrachte Kunststoffstege angeordnet sind. Um für den Strukturträger preiswerte Halbzeuge als Hohlprofile verwenden zu können, wobei der Strukturträger dennoch in den torsionsbeanspruchten, vorherbestimmbaren Bereichen eine hohe Verwindungssteifigkeit aufweist, ist in Teilbereichen die Öffnung des Hohlprofils mittels an dessen längslaufenden Randbereichen fest angesetzter, steifer Wandelemente geschlossen.Such a structural support as a body component of passenger or small trucks, in particular for front-end modules of such vehicles, consists of a hollow profile made of a rigid material that has an opening along one of its long sides that is delimited by its longitudinal edge areas on both sides and in which plastic webs are placed in the injection molding process. In order to be able to use inexpensive semi-finished products as hollow profiles for the structural beam, the structural beam nevertheless having a high torsional stiffness in the torsionally stressed, predeterminable areas, the opening of the hollow profile is closed in partial areas by means of rigid wall elements attached to its longitudinal edge areas.
Description
Die Erfindung bezieht sich auf einen Strukturträger gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a structural support according to the features of the preamble of Patent claim 1.
Bei einem solchen Strukturträger handelt es sich um ein Hybrid-Bauteil aus einem Verbund eines steifen, festeren Werkstoffs und des die Stege im Hohlprofil bildenden Kunststoffs. Insbesondere kommen hierfür Holprofile aus Stahl zum Einsatz, wobei durch die im Spritzgießverfahren in das Hohlprofil eingebrachten Kunststoffstege eine gute Biegefestigkeit erreicht werden kann. Allerdings weisen diese Strukturträger eine relativ geringe Verwindungssteifigkeit auf, die weitaus geringer als die Verwindungssteifigkeit von geschlossenen Metallprofilen oder Profilen aus Faserverbundstoffen ist. Deshalb verwendet man bei höheren Anforderungen an die Verwindungssteifigkeit hydrogeformte Hohlprofile für Hybridstrukturen der in Rede stehenden Art, um eine rundum geschlossene Wandung der Strukturträger zu erzielen. Die Hydroformung ist allerdings ein sehr kostenintensives Verfahren.at such a structural support it is a hybrid component from a composite of a stiff, stronger material and the Webs in the hollow profile forming plastic. In particular, this Holprofile come made of steel for use, whereby by the injection molding in the hollow profile introduced plastic webs a good bending strength can be achieved. However, these structural supports have one relatively low torsional stiffness, which is much lower as the torsional rigidity of closed metal profiles or profiles of fiber composites. That's why you use at higher Requirements for torsional rigidity hydroformed hollow sections for hybrid structures the type in question, around a completely closed wall of the Structural support too achieve. However, hydroforming is a very expensive process Method.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Strukturträger der eingangs genannten Art zu schaffen, für den preiswerte Halbzeuge als Hohlprofile verwendet werden können, wobei der Strukturträger dennoch in den torsionsbeanspruchten, vorherbestimmbaren Bereichen eine hohe Verwindungssteifigkeit aufweist.Of the The invention is therefore based on the object, a structural support of to create the aforementioned type, for the reasonably priced semi-finished products can be used as hollow profiles, wherein the structural support nevertheless in the torsionsbeanspruchten, predictable areas one has high torsional rigidity.
Diese Aufgabe wird bei einem Strukturträger der oben genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.These Task is in a structural support of the above type solved by the characterizing features of claim 1.
Für die Erfindung ist wesentlich, daß mittels der im Öffnungsbereich an das Hohlprofil angesetzten Wandelemente eine hohe Verwindungssteifigkeit zumindest partiell in Längsrichtung des Hohlprofils gesehen erreicht werden kann, die weitgehend der eines in Umfangsrichtung geschlossenen Hohlprofils entspricht. Die Ausbildung des Strukturträgers als Hybridbauteil wird dadurch nicht beeinträchtigt, so daß jedenfalls an den gewünschten Stellen die Biege- und Knickfestigkeit nach wie vor gegeben ist, andererseits in den torsionsbeanspruchten Bereichen der Strukturträger vor allem eine hohe Verwindungssteifigkeit aufweist.For the invention is essential that by means of in the opening area at the hollow profile attached wall elements a high torsional rigidity at least partially in the longitudinal direction the hollow profile can be achieved, which is largely the one corresponds in the circumferential direction closed hollow profile. Training of the structural support as a hybrid component is not affected, so that anyway to the desired Provide the bending and buckling strength is still given on the other hand in the torsionsbeanspruchten areas of the structural support all has a high torsional rigidity.
