Abstract
Aus maßgeschneiderten Einzelplatinen (tailored blanks) zusammengesetzte Platine mit zwei Seitenteilen und einem Mittelteil, die über im wesentlichen in Längsrichtung verlaufende Schweißnähte miteinander verbunden sind, für ein durch anschließende Umformung zu erzielendes Bodenblech eines Fahrzeugs, dadurch gekennzeichnet, daß die Platine (1) wenigstens eine weitere Einzelplatine (5) umfaßt, welche stirnseitig über eine querverlaufende Schweißnaht (8) mit der aus den Seitenteilen (2, 3) und dem Mittelteil (4) gebildeten Teilplatine verschweißt ist.Out customized Individual blanks Composite board with two side panels and a middle section that over essentially in the longitudinal direction extending welds interconnected are for one by subsequent Forming to be achieved floor panel of a vehicle, characterized that the Board (1) comprises at least one further individual board (5), which over the front a transverse weld (8) formed with the from the side parts (2, 3) and the central part (4) Partial board welded is.
Description
Die Erfindung betrifft eine aus maßgeschneiderten Einzelplatinen, sogenannten tailored blanks, zusammengesetzte Platine für ein Fahrzeug-Bodenblech entsprechend dem Oberbegriff des Patentanspruchs 1. Dabei sind die Einzelplatinen hinsichtlich der Blechdicken, der Materialqualitäten und der Oberflächenbeschaffenheit auf die spätere Beanspruchung abgestimmt, was sich positiv insbesondere auf das Gewicht des fertigen Bauteils, im vorliegenden Fall also des Bodenblechs, auswirkt.The Invention relates to a tailor made Single blanks, so-called tailored blanks, composite board for a Vehicle floor panel according to the preamble of the claim 1. The individual boards are in terms of sheet thickness, the material qualities and the surface texture to the later Stress matched, which is positive in particular to the Weight of the finished component, in this case the bottom plate, effect.
Ein gattungsgemäßes Bodenblech aus drei Einzelplatinen, nämlich zwei Seitenteilen und einem zur Bildung des Tunnels bestimmten Mittelteil, die durch zwei im wesentlichen in Längsrichtung verlaufende Schweißnähte miteinander zu einer Mehrfachplatine verbunden worden sind, bevor aus dieser durch eine Umformoperation, z. B. durch Tiefziehen, das Bodenblech entsteht, ist aus Christoph Schneider, Adam Frings: "Laserstrahlgeschweißte Platinen – ein neuartiges Konstruktionselement" in "Bleche Rohre Profile", 40 (1993) 4, Seiten 304 bis 306 bekannt.One generic floor panel from three single boards, namely two side parts and a central part intended to form the tunnel, the by two substantially longitudinally extending welds together have been connected to a multiple board before passing through this a forming operation, e.g. B. by deep drawing, the floor panel is formed, is from Christoph Schneider, Adam Frings: "Laser beam welded blanks - a novel Construction element "in" Sheets Pipes Profile ", 40 (1993) 4, pages 304-306 known.
Die Aufgabe der Erfindung besteht darin, das vorgenannte Bodenblech hinsichtlich seiner Beanspruchung wie Biegung, Torsion und belastungsgerechter Steifigkeit – insbesondere im Crashfall – zu verbessern. Es hat sich nämlich in Versuchsreihen herausgestellt, daß der vordere Bereich des Bodenblechs, also der Fußraum für Fahrer und Beifahrer, anderen Belastungen ausgesetzt ist als der übrige Bereich. So wie man bereits das bekannte Bodenblech aus Einzelplatinen für die Seitenteile und das den Tunnel bildende Mittelteil zusammengesetzt hat, die sich nicht nur in ihren Abmessungen einschließlich der Blechdicke, sondern auch in der Werkstoffgüte und der Oberflächenbehandlung unterscheiden beziehungsweise unterscheiden können, so ist es auch zweckmäßig, das Bodenblechvorderteil erfindungsgemäß als separate Einzelplatine einzubringen und sie gemäß dem kennzeichnenden Teil des Patentanspruchs 1 mit der Platine zu verbinden.The The object of the invention is the aforementioned floor panel in terms of its stress such as bending, torsion and load-bearing Stiffness - especially in the event of a crash - to improve. It has become proved in test series that the front area of the floor panel, So the footwell for drivers and passenger, is exposed to different loads than the rest of the area. Just as you already have the well-known base plate made of single boards for the side panels and the middle part forming the tunnel has been assembled, the not only in their dimensions including the sheet thickness, but also in the material quality and the surface treatment distinguish or distinguish, so it is also appropriate that Bottom plate front part according to the invention as a separate single board and they according to the characterizing Part of claim 1 to connect to the board.
