Abstract
Description
Die Erfindung betrifft eine Tür eines Kraftfahrzeuges, umfassend ein Außenblech, ein Innenblech, einen auf der Türinnenseite angeordneten plattenförmigen Träger für verschiedene An- und Einbauaggregate sowie Verstärkungsbereiche für Türfunktionselemente und einen eingebauten Versteifungsträger als Seitenaufprallschutz.The The invention relates to a door of a motor vehicle, comprising an outer panel, an inner panel, one on the inside of the door arranged plate-shaped carrier for various attachment and installation units as well as reinforcement areas for door function elements and a built-in Stiffening support as side impact protection.
Türen dieser oder ähnlicher Art sind in verschiedenen Ausführungen bekannt. Solche Türen müssen für die Fahrzeuginsassen einen guten Schutz bei einem Seitenaufprall bieten. Darüber hinaus müssen sie die Möglichkeit bieten, in ihnen verschiedene Aggregate, wie Fensterhebermechanik, Lautsprecher und dgl., unterzubringen.doors this or similar type are in different versions known. Such doors must be for the Provide vehicle occupants with good protection in the event of a side impact. In addition, they have the opportunity offer, in them various units, such as window regulator mechanism, speakers and the like., To accommodate.
Bei einer aus der Praxis bekannten Tür der eingangs genannten Art umfasst das tiefgezogene Innenblech den Träger für verschiedene An- und Einbauaggregate. Damit sich für diese Aggregate eine genügende Einbautiefe ergibt, muss das Innenblech aus gut tiefziehfähigem Stahl bestehen. Ein solcher Stahl trägt allerdings zur Versteifung der Tür nur wenig bei. Deshalb ist als Seitenaufprallschutz an dem Türinnenblech ein eigenständiger Versteifungsträger aus hochfestem Stahlblech angebracht. Darüber hinaus sind in den Verstärkungsbereichen für die Türfunktionselemente, wie Scharniere und Schloss, Profilelemente aus hochfestem Stahl angebracht. Eine solche Tür ist wegen der Vielzahl der zusammenzubauenden Einzelelemente aufwendig zu fertigen. Auch ist ihr Verhältnis von Steifigkeit und Gewicht nicht optimal.at a known from practice door of the aforementioned Art includes the deep-drawn inner sheet the carrier for various attachment and installation units. Thus, for this Aggregates results in a sufficient installation depth, the inner panel must good deep-drawing steel. Such a steel carries but only a little to stiffen the door. Therefore is as a side impact protection on the inner door panel a separate Stiffening beams made of high-strength sheet steel attached. In addition, in the reinforcement areas for the door function elements, such as hinges and Lock, profile elements made of high-strength steel attached. Such Door is because of the large number of individual elements to be assembled expensive to manufacture. Also, their ratio of stiffness and weight not optimal.

Der Erfindung liegt die Aufgabe zugrunde, eine Tür für ein Kraftfahrzeug zu schaffen, die eine hohe Eigensteifigkeit mit Seitenaufprallschutz aufweist und bei der bei geringem Fertigungsaufwand An- und Einbauaggregate untergebracht werden können.Of the Invention is based on the object, a door for to create a motor vehicle that has a high inherent rigidity Has side impact protection and in the case of and installation units can be accommodated.
Diese Aufgabe wird erfindungsgemäß bei einer Tür der eingangs genannten Art dadurch gelöst, dass das Innenblech und der Versteifungsträger als ein integrales, rahmenförmiges, die Versteifungsbereiche umfassendes Bauteil aus hoch- bis höchstfestem Stahlblech ausgebildet und warmumgeformt sind, und dass der Träger für die An- und Einbauaggregate über einen Aufnahmerahmen an dem Innenblech befestigt ist.These Task is according to the invention in a door of the type mentioned solved in that the inner panel and the stiffening support as an integral, frame-shaped, the stiffening areas comprehensive component of high to ultra high strength Steel sheet is formed and hot formed, and that the carrier for the attachment and installation units via a mounting frame is attached to the inner panel.
Die erfindungsgemäße Tür lässt sich mit vergleichsweise geringem Aufwand fertigen, weil das Innenblech und der dem Seitenaufprallschutz dienende Versteifungsträger einstückig, d. h. als integrales Bauteil ausgebildet sind und aus hochfestem bis höchstfestem Stahlblech bestehen. Wegen der Warmumformung lässt sich auch die gewünschte Profiltiefe des Bauteils erreichen. Das bedeutet, dass dieses integrale Bauteil der Tür nicht nur die gewünschte Eigensteifigkeit sondern auch den gewünschten Schutz bei einem Seitenaufprall gibt. Darüber hinaus können wegen des Einsatzes des hoch- bis höchstfesten Stahlbleches auch Türscharniere und dergleichen unmittelbar oder mittelbar an diesem Stahlblech angebracht werden. Separate Verstärkungselemente für Türscharniere oder dgl. sind nicht erforderlich. Der gewünschte Umformgrad des hoch- bis höchstfesten Stahlbleches lässt sich in einem oder zwei Schritten erreichen. Bei einem einstufigen Umformen wird das Stahlblech auf Austenitisierungstemperatur erwärmt, warmumgeformt und gehärtet, insbesondere pressgehärtet. Bei einem zweistufigen Verfahren erfolgt zunächst eine Kaltumformung, wobei insbesondere der maximal mögliche Umformgrad möglicht ausgeschöpft werden sollte, und dann nach Erwärmung bis auf Austenitisierungstemperatur eine Warmumformung ggf. mit abschließender Härtung, insbesondere Presshärtung. Entsprechend der später im Betrieb zu erwartenden unterschiedlichen Beanspruchungen in einzelnen Bereichen des Bauteils können durch bereichsweise unterschiedliche Wärmebehandlungen des Bauteils unterschiedliche Härtezonen im Bauteil eingestellt werden. So kann das Innenblech in hochbelasteten Bereichen, insbesondere in Bereichen für Türfunktionselemente, partiell unterschiedliche Festigkeiten und Bruchdehnungen gegenüber den anderen Bereichen des Bauteils aufweisen. Durch den Einsatz eines von einem Aufnahmerahmen getragenen Trägers kann dieser ohne Rücksicht auf die wichtigen Anforderungen an die Tür hinsichtlich Steifigkeit und Seitenaufprallschutz ausschließlich nach den Anforderungen für die An- und Einbauaggregate gestaltet sein.The door according to the invention can be finished with comparatively little effort, because the inner panel and the lateral impact protection serving stiffening support in one piece, ie formed as an integral component and consist of high-strength to ultra-high strength steel sheet. Because of the hot forming can also achieve the desired profile depth of the component. This means that this integral component gives the door not only the desired inherent rigidity but also the desired protection in the event of a side impact. In addition, because of the use of high to ultra high strength steel sheet and door hinges and the like can be attached directly or indirectly to this steel sheet. Separate reinforcement elements for door hinges or the like are not required. The desired degree of deformation of the high to highest strength Steel sheet can be reached in one or two steps. In a single stage forming, the steel sheet is heated to austenitizing temperature, hot worked and cured, especially press hardened. In a two-stage process, first a cold forming, in particular the maximum possible degree of deformation should be exploited as possible, and then after heating to Austenitisierungstemperatur a hot forming optionally with final curing, in particular press hardening. In accordance with the different stresses to be expected later in the operation in individual regions of the component, it is possible to set different hardness zones in the component by way of different heat treatments of the component in certain regions. Thus, the inner panel in highly loaded areas, especially in areas for door function elements, partially different strengths and elongation at break relative to the other areas of the component. Through the use of a supported by a support frame carrier this can be designed without regard to the important requirements for the door in terms of stiffness and side impact protection exclusively to the requirements for the attachment and installation units.
So können nach einer Ausgestaltung der Erfindung der Träger für die An- und Einbauaggregate und der Aufnahmerahmen als einteiliges Bauteil ausgebildet sein. Der Träger und/oder der Aufnahmerahmen können aus Stahlblech, Kunststoff oder einer Hybridstruktur (Metall/Kunststoff) bestehen. Da die Einbautiefe für die Aggregate praktisch allein durch den Aufnahmerahmen realisiert wird, sollte dieser entweder aus weichem Tiefziehstahl, Aluminium, Kunststoff oder einer Hybridstruktur bestehen.So can according to an embodiment of the invention, the carrier for the attachment and installation units and the mounting frame be formed as a one-piece component. The carrier and / or The mounting frame can be made of sheet steel, plastic or a hybrid structure (metal / plastic) exist. Because the installation depth for the aggregates practically alone by the mounting frame if it is made of either soft deep-drawn steel, Aluminum, plastic or a hybrid structure exist.
Die Befestigung zwischen Innenblech und Aufnahmerahmen kann eine Punktschweiß- und/oder Schraub- und/oder Niet- und/oder Laserschweiß- und/oder Klebeverbindung sein.The Attachment between inner panel and mounting frame may be a spot welding and / or Screw and / or rivet and / or laser welding and / or Be adhesive bond.
