Abstract
Doppellagenblech (1) für ein Kraftfahrzeug zur Aufnahme einer einwirkenden Last, das eine erste und eine zweite miteinander verbundene Platte (3,4) aufweist, wobei mindestens eine der beiden Platten Noppen (5) aufweist, an denen die Platten miteinander verbunden sind, dadurch gekennzeichnet, daß auf dem Umfang mindestens einer Noppe (5) Versteifungssicken (7) ausgebildet sind.Double-layer plate (1) for a motor vehicle for receiving an applied load, the first and a second interconnected plate (3, 4), wherein at least one of the two plates nubs (5), where the plates are interconnected, characterized that on the circumference of at least one knob (5) stiffening beads (7) formed are.
Description
Die Erfindung betrifft ein Doppellagenblech für ein Kraftfahrzeug zur Aufnahme einer einwirkenden Last gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a double-layered sheet for a motor vehicle for receiving an acting load according to the preamble of claim 1.
Das Doppellagenblech weist eine erste obere und eine zweite untere Platte auf, die miteinander verbunden sind, wobei zur Realisierung einer Beabstandung dieser Platte zwischen der ersten und der zweiten Platte entsprechende Noppen vorgesehen sind, wobei die Noppen an wenigstens einer der Platten ausgebildet sind.The Double-layered sheet has a first upper and a second lower plate auf, which are connected to each other, wherein the realization of a Spacing this plate between the first and second plates corresponding nubs are provided, wherein the knobs on at least one of the plates are formed.
Die
Derartige Techniken werden eingesetzt, um beim Bau eines Kraftfahrzeugs möglichst viel Gewicht einzusparen. Dies hat zur Folge, daß auch tragende Bauteile nur ein möglichst geringes Gewicht aufweisen. So werden auch für Tragplatten bzw. Doppellagenbleche möglichst dünnwandige Bleche verwendet, was zur Folge hat, daß deren Steifigkeit bzw. deren Festigkeit nicht immer optimal ausgebildet ist. Insbesondere wenn Tragplatten bzw. Doppellagenbleche noch entsprechend ihrer späteren Verwendung umgeformt, beispielsweise tiefgezogen werden müssen, hat die Praxis gezeigt, daß die endgültige Form der Tragplatte bzw. des Doppellagenbleches dann nicht optimal ausgebildet ist, weil insbesondere die zwischen der ersten und zweiten Platte vorgesehenen Noppen durch die beim Tiefziehen auftretenden Kräfte so eindrückt worden sind, daß die erste und zweite Platte nicht mehr optimal zueinander beabstandet ist.such Techniques are used to build a motor vehicle as possible to save a lot of weight. This has the consequence that even load-bearing components only one possible have low weight. So are also for support plates or double-layer sheets preferably thin Sheets used, with the result that their rigidity or their Strength is not always optimally designed. Especially if Support plates or double-layer sheets still according to their later use formed, for example, must be thermoformed, has shown the practice that the final Shape of the support plate or the double-layer sheet then not optimal is formed, because in particular the between the first and second Plate provided nubs by occurring during deep drawing personnel so impressed have been that the first and second plate no longer optimally spaced is.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Doppellagenblech derart auszugestalten und weiterzubilden, daß dessen Steifigkeit bzw. Festigkeit erhöht ist, ohne daß damit eine wesentliche Gewichtszunahme verbunden ist.Of the Invention is therefore based on the object, a double-layer sheet to design and develop such that its rigidity or strength elevated is without it a substantial weight gain is associated.
Diese Aufgabe wird durch ein Dopellagenblech nach Anspruch 1 gelöst. Die Unteransprüche beschreiben bevorzugte Weiterbildungen.These Task is solved by a double layer sheet according to claim 1. The Describe subclaims preferred developments.
Durch die Versteifungssicken auf dem Umfang der Noppen sind die Steifigkeit und die Festigkeit des aus der ersten und zweiten Platte gebildeten Doppellagenblechs erhöht. Die mit den Versteifungssicken versehenen Noppen sind nunmehr schwerer, also nur durch größere Kräfte zusammendrückbar. Dies ist insbesondere beim Tiefziehen der aus einer ersten und zweiten Platte gebildeten Tragplatte (Doppellagenblech) von Vorteil, da der eingangs erwähnte nachteilhafte Effekt des Zusammendrückens des Doppellagenblechs weitgehend vermieden wird und eine bessere Beabstandung der ersten und zweiten Platte zueinander – nunmehr auch nach dem Tiefziehen – gewährleistet ist.By the stiffening beads on the circumference of the knobs are the stiffness and the strength of the double-layer sheet formed of the first and second plates elevated. The provided with the stiffening beads knobs are now heavier, so only squeezable by larger forces. This is in particular during deep drawing of a first and second Plate formed support plate (double-layer sheet) advantageous because the initially mentioned disadvantageous Effect of squeezing the double-layer sheet is largely avoided and a better Spacing of the first and second plates to each other - now even after deep drawing - guaranteed is.
Es gibt nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Tragplatte in vorteilhafter Weise auszugestalten und weiterzubilden. Hierfür darf an dieser Stelle auf die dem Patentanspruch 1 nachgeordneten Patentansprüche verwiesen werden. Im übrigen wird nun eine Ausführungsform der Erfindung anhand einer Zeichnung näher erläutert. In der Zeichnung zeigtIt Now there are a lot of ways that Support plate according to the invention to design and develop in an advantageous manner. For this may at this Reference is made to the claims subordinate to claim 1 become. Furthermore now becomes an embodiment of the invention explained in more detail with reference to a drawing.
