Abstract

Disclosed is a structure support as a body component of passenger cars or small trucks, especially for front end modules of such motor vehicles. Said structure support is composed of a hollow profiled member (1) which is made of a rigid material and is provided with an opening (2) along one of the longitudinal faces thereof, said opening (2) being defined by the edge regions thereof that extend longitudinally on both sides. Plastic webs (4) introduced in an injection molding process are disposed in the hollow profiled member (1). In order to be able to use inexpensive semifinished products as hollow profiled members for the structure support while providing the structure support with great rigidity in the predetermined zones that are subject to torsion, the opening (2) of the hollow profiled member (1) is closed in some areas thereof by means of rigid wall elements (5) which are attached in a fixed manner to the longitudinally extending edge regions (3) thereof. The plastic (8) forming the webs connects the hollow profiled member (1) in a fixed manner to the wall elements (5).

Description

STRUKTURTRÄGER ALS KAROSSERIEBAUTEILSTRUCTURAL CARRIER AS A BODYWORK PART
Technisches GebietTechnical area
Die Erfindung bezieht sich auf einen Strukturträger gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a structural support according to the features of the preamble of patent claim 1.
Stand der TechnikState of the art
Bei einem solchen Strukturträger handelt es sich um ein Hy- brid-Bauteil aus einem Verbund eines steifen, festeren Werkstoffs und des die Stege im Inneren des Hohlprofil bildenden Kunststoffs. Insbesondere kommen hierfür Hohlprofile aus Stahl zum Einsatz, wobei durch die im Spritzgießverfah- ren in das Hohlprofil eingebrachten Kunststoffstege eine gute Biegefestigkeit erreicht werden kann. Allerdings weisen diese Strukturträger eine relativ geringe Verwindungs- steifigkeit auf, die weitaus geringer als die Verwindungs- steifigkeit von geschlossenen Metallprofilen oder Profilen aus Faserverbundstoffen ist. Deshalb verwendet man bei höheren Anforderungen an die Verwindungssteifigkeit hydroge- formte 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.Such a structural support is a hybrid component made of a composite of a stiff, firmer material and the plastic forming the webs in the interior of the hollow profile. In particular, hollow sections made of steel are used for this, whereby a good flexural strength can be achieved by the plastic webs introduced into the hollow profile in the injection molding process. However, these structural supports have a relatively low torsional rigidity, which is much lower than the torsional rigidity of closed metal profiles or profiles made of fiber composites. For higher demands on the torsional rigidity, therefore, use is made of hydroformed hollow profiles for hybrid structures of the type in question in order to achieve a completely closed wall of the structural members. However, hydroforming is a very expensive process.
Die ErfindungThe invention
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 torsions- beanspruchten, vorherbestimmbaren Bereichen eine hohe Ver- windungssteifigkeit aufweist.The invention is therefore an object of the invention to provide a structural support of the type mentioned, for the inexpensive semi-finished products can be used as hollow profiles, wherein the structural support nevertheless has a high stiffness in the torsion-stressed, predeterminable areas.
Diese Aufgabe wird bei einem Strukturträger der oben genannten Art dadurch gelöst, daß in Teilbereichen die Öffnung des Hohlprofils mittels an dessen längslaufenden Randbereichen angesetzter, steifer Wandelemente geschlossen ist, wobei der die Stege bildende Kunststoff das Hohlprofil mit den Wandelementen fest verbindet.This object is achieved in a structural support of the type mentioned above in that in partial areas, the opening of the hollow profile is closed by means attached to the longitudinal edge regions, rigid wall elements, wherein the webs forming plastic firmly connects the hollow profile with the wall elements.
Für die Erfindung ist wesentlich, daß mittels der im Öffnungsbereich an das Hohlprofil angesetzten Wandelemente ei- ne 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 je- denfalls 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.It is essential for the invention that, by means of the wall elements attached to the hollow profile in the opening region, a high torsional stiffness can be achieved, at least partially seen in the longitudinal direction of the hollow profile, which largely corresponds to a hollow profile closed in the circumferential direction. The formation of the structural support as a hybrid component is not impaired, so that in any case at the desired locations, the bending and buckling strength is still given, on the other hand in the torsionsbeanspruchten areas of the structural support above all has a high torsional rigidity.
Vorteilhafte Ausgestaltungsmerkmale der Erfindung ergeben sich aus den Unteransprüchen.Advantageous design features of the invention will become apparent from the dependent claims.
Kurzbeschreibung der ZeichnungsabbildungenBrief description of the drawing illustrations
Die Erfindung wird nachfolgend anhand der Zeichnung an Aus führungsbeispielen noch näher erläutert. Dabei zeigen:The invention will be described below with reference to the drawing guide examples explained in more detail. Showing:
Fig. 1 eine perspektivische Vorderansicht eines Abschnittes eines Strukturträgers undFig. 1 is a front perspective view of a portion of a structural support and
Fig. 2 eine perspektivische Rückansicht des Strukturträgers nach Fig. 1.FIG. 2 shows a perspective rear view of the structural support according to FIG. 1. FIG.
Weg zur Ausführung der ErfindungWay to carry out the invention
Im einzelnen ist in der Zeichnung ein Hohlprofil 1 wiedergegeben, welches im Querschnitt im wesentlichen C- oder U- förmig ist. Dadurch weist das Hohlprofil 1 an einer seiner Längsseiten eine durchgehend längslaufende Öffnung 1 auf, die durch in der Öffnungsebene flächig ausgebildete Randbereiche 3 beidseits eingegrenzt sind. Da die flächigen Randbereiche 3 am Hohlprofil 1 durch daran abgewinkelte, miteinander parallele Stege 3.1 gebildet sind, die am Hohlprofil 1 nach außen hin wegstehen, ist beim dargestellten Aus- führungsbeispiel das Hohlprofil 1 ein sogenanntes Hutprofil.In detail, a hollow profile 1 is reproduced in the drawing, which is in cross-section substantially C- or U-shaped. As a result, the hollow profile 1 on one of its longitudinal sides on a continuous longitudinal opening 1, which are bounded on both sides by flat in the opening plane formed edge portions. Since the flat edge regions 3 are formed on the hollow profile 1 by angled parallel thereto webs 3.1, which protrude on the hollow profile 1 to the outside, in the illustrated embodiment, the hollow profile 1 is a so-called hat profile.
Das Hohlprofil 1 ist mittels innenliegender Stege 4 versteift, die sich zwischen den seitlichen Flanken des Hohl- profus 1 und bis hin zum Grund des Hohlprofils 1 erstrek- ken. Die Stege 4 bestehen aus angespritzem Kunststoff 8, der zum Teil bis auf die in Fig. 2 erkennbare Rückseite des Hohlprofils 1 reicht und dort partiell einen Überzug bildet. Die Stege 4 können als einfache Querwände in das Inne- re des Hohlprofils 1 oder als miteinander kreuzende Rippen eingebracht sein.The hollow profile 1 is stiffened by means of internal webs 4, which extend between the lateral flanks of the hollow profile 1 and up to the bottom of the hollow profile 1. The webs 4 are made of molded plastic 8, which extends in part to the recognizable in Fig. 2 back of the hollow section 1 and there partially forms a coating. The webs 4 can be used as simple transverse walls in the inner be introduced of the hollow section 1 or as intersecting ribs.
In Teilbereichen ist die Öffnung 2 des Hohlprofils 1 mit- tels Wandelementen 5 geschlossen. Fig. 1 zeigt zwei solcher Wandelemente 5, die mit ihren Längsrändern 6 auf die Randbereiche 3 des Hohlprofils 1 aufgesetzt sind. Es besteht eine feste Verbindung zwischen den Längsrändern 6 der Wandelemente 5 und den Randbereichen 3 des Hohlprofils 1, so- wohl das Hohlprofil 1 als auch die Wandelemente 5 bestehen aus einem steifen Werkstoff, bei dem es sich um einen Metall- oder Faserverbundwerkstoff handelt. So können die Wandelemente 5 mit dem Hohlprofil 1 entlang dessen Randbereichen 3 mittels Klebepunkten fixiert bzw. vorfixiert sein. Da in bevorzugter Ausführung das Hohlprofil 1 und die Wandelemente 5 aus Stahlblech bestehen, kann die Fixierung der Wandelemente auch mittels Schweißpunkten 10 vorgenommen werden, die in Fig. 1 zu erkennen sind, in jedem Fall trägt der Kunststoff 8, der die Stege 4 im Inneren des Hohlpro- fils 1 bildet, wesentlich zur festen Verbindung zwischen dem Hohlprofil 1 und den Wandelementen 5 bei.In partial areas, the opening 2 of the hollow profile 1 is closed by means of wall elements 5. Fig. 1 shows two such wall elements 5, which are placed with their longitudinal edges 6 on the edge regions 3 of the hollow section 1. There is a firm connection between the longitudinal edges 6 of the wall elements 5 and the edge regions 3 of the hollow profile 1, both the hollow profile 1 and the wall elements 5 are made of a rigid material, which is a metal or fiber composite material. Thus, the wall elements 5 can be fixed or prefixed to the hollow profile 1 along its edge regions 3 by means of adhesive dots. Since in a preferred embodiment, the hollow section 1 and the wall elements 5 are made of sheet steel, the fixing of the wall elements can also be made by means of welds 10, which can be seen in Fig. 1, in each case carries the plastic 8, the webs 4 in the interior the hollow profile 1 forms, substantially to the solid connection between the hollow section 1 and the wall elements 5 at.
Im Bereich der Wandelemente 5 ist das Hohlprofil 1 in Um- fangsrichtung rundum geschlossen und hat hier dadurch eine Torsionssteifigkeit, die im wesentlichen der eines Rohres entspricht. Die versteifenden Wandelemente 5 werden deshalb bei dem kompletten Strukturträger an solchen Stellen des Hohlprofils 1 vorgesehen, die einer Beanspruchung im wesentlichen durch Verwindung ausgesetzt sind. Im Falle der Vorfixierung zwischen dem Hohlprofil 1 und den Wandelementen 5 kann die Komplettierung des Hohlprofils 1 zu einem Hybridbauteil durch Verbindung mit dem Kunststoff 8, der die Stege 4 bildet, erst im nachhinein im Spritzguß- verfahren erfolgen. Die die Biegesteifigkeit des Hohlprofils 1 erhöhenden Stege 4 können sich hierbei nur dort im Innern des Hohlprofils ausbilden, wo eine Abdeckung der Öffnung 2 des Hohlprofils 1 durch die Wandelemente 5 nicht besteht. Demgemäß ist der Innenraum 9 des Hohlprofils 1 hinter den Wandelementen 5 frei von den Stegen 4 oder den Überzügen, die ebenfalls aus dem Kunststoff 8 gebildet sein können.In the area of the wall elements 5, the hollow profile 1 is completely enclosed in the circumferential direction and as a result has a torsional stiffness which essentially corresponds to that of a tube. The stiffening wall elements 5 are therefore provided in the entire structural support at those points of the hollow profile 1, which are exposed to a stress substantially by twisting. In the case of prefixing between the hollow profile 1 and the wall elements 5, the completion of the hollow profile 1 to a hybrid component by connection with the plastic 8, which forms the webs 4, carried out only later in the injection molding. The bending stiffness of the hollow profile 1 increasing webs 4 can form here only in the interior of the hollow profile, where a cover of the opening 2 of the hollow profile 1 by the wall elements 5 does not exist. Accordingly, the interior 9 of the hollow profile 1 is behind the wall elements 5 free of the webs 4 or the coatings, which may also be formed from the plastic 8.
Wie aus Fig. 2 hervorgeht, bildet der Kunststoff 8 vor al- lern an der konvex gewölbten Rückseite des Hohlprofils 1 teilweise einen Überzug, der die Randstege 3.1 des Hohlprofils 1 umgreift und hier die Randbereiche 6 der Wandelemente 5 als streifenartiger Überzug 8.2 überdeckt. Je nach der sonstigen Befestigungsart der Wandelemente 5 trägt der Kunststoff 8 der Hybridbauteile wesentlich zur Fixierung der Wandelemente 5 an dem Hohlprofil 1 bei.As can be seen from FIG. 2, the plastic 8 partially forms a coating on the convexly curved rear side of the hollow profile 1, which surrounds the edge webs 3.1 of the hollow profile 1 and here covers the edge regions 6 of the wall elements 5 as a strip-like coating 8.2. Depending on the other type of fastening of the wall elements 5, the plastic 8 of the hybrid components contributes substantially to the fixing of the wall elements 5 on the hollow profile 1.
Weiter weist das Hohlprofil 1 an diskreten Stellen oder in größeren Bereichen Durchbrechungen 11 auf, die für das Durchspritzen des Kunststoffs 8 vorgesehen sind. Diese Durchspritzstellen oder -bereiche fördern nicht nur den Verbund des Kunststoffs 8 mit dem Hohlprofil 1, sie ermöglichen es ferner, an der konvex gewölbten Rückseite des Hohlprofils 1 vorstehende, aus dem Kunststoff 8 bestehende Befestigungselemente, wie in Gestalt von Laschen 12.1 oder Hakenelementen 12.2, auszubilden. Insoweit bildet der Kunststoff 8 Funktionselemente, welche bei der Verwendung des Strukturträgers als Karosseriebauteil die Verbindung mit anderen Fahrzeugbauteilen ermöglichen. Die Durchbre- chungen 11 des Hohlprofils 1 können jedoch auch lediglich als kreisrunde oder anders gestaltete Löcher vorgesehen sein, um Durchspritzpunkte 12.2 zu bilden, die allein der weiter verbesserten Verbindung zwischen dem Kunststoff 8 und dem Hohlprofil 1 dienen. Next, the hollow profile 1 at discrete locations or in larger areas openings 11, which are provided for the injection of the plastic 8. These injection points or areas not only promote the composite of the plastic 8 with the hollow profile 1, they also make it possible, at the convex curved back of the hollow section 1 projecting, consisting of the plastic 8 fasteners, such as in the form of tabs 12.1 or Hook elements 12.2, form. In that regard, the plastic 8 forms functional elements which enable the connection with other vehicle components when using the structural support as a body component. The breakthroughs 11 of the hollow section 1, however, can also be provided only as circular or differently shaped holes to form injection points 12.2, which serve solely the further improved connection between the plastic 8 and the hollow profile 1.
