Abstract

The invention relates to a door leaf for a railway vehicle, particularly for a railway car, comprised of at least two painted metal sheets, which are made from an aluminum alloy, mounted on a door leaf frame placed between these metal sheets, glued to said door leaf frame and/or to one another, and which form a pocket between them that is at least partially filled with a honeycomb body and/or with a foamed material. The invention is characterized in that the coating of the metal sheets consists of at least one primary coat of a stoved finish that is applied before the metal sheets are cut to size and shaped.

Description

Türflügel von Eisenbahnfahrzeugen Door wing of railway vehicles
Die Erfindung betrifft einen Türflügel für ein Schienenfahrzeug, insbesondere einen Waggon, welcher aus zumindest zwei lackierten Blechen aus einer Aluminiumlegierung besteht, die auf einem zwischen diesen Blechen angeordneten Türflügelrahmen montiert und mit diesem und/oder untereinander verklebt sind und zwischen sich eine Tasche bilden, die mit einem Wabenkörper und/oder einem geschäumten Material zumindest teilweise gefüllt ist. Dazu kommt noch der Türmechanismus samt den Beschlägen, doch betrifft die Erfindung im Besonderen die Bleche.The invention relates to a door wing for a rail vehicle, in particular a wagon, which consists of at least two painted sheets of an aluminum alloy, which are mounted on a door wing frame arranged between these sheets and glued to and / or with each other and form a pocket between them is at least partially filled with a honeycomb body and / or a foamed material. In addition, there is the door mechanism including the fittings, but the invention relates in particular to the metal sheets.
Eisenbahnfahrzeuge, auch Personenwaggons, von der U-Bahn bis zu Hochgeschwindigkeitszügen, werden mit äußerst aggressiven Flüssigkeiten gereinigt. Diese Reinigung stellt auch zeitgemäße Türen, die im wesentlichen aus einer Aluminiumlegierung bestehen, vor große Probleme. Man muß dabei bedenken, dass moderne Eisenbahntüren im wesentlichen aus zwei Blechen einer Aluminiumlegierung (im folgenden einfach „Aluminium") bestehen die miteinander verklebt sind, im Bereich zumindest jeweils einer fluchtenden Öffnung ein Fenster aufweisen, in ihrem Inneren einen Waben- bzw. Schaumkern aufweisen, wei- ters einen Öffhungsmechanismus u.dgl. mehr, und dass die Metallteile (Deckbleche außen und innen) lackiert sind.Railway vehicles, including passenger cars, from the subway to high-speed trains, are cleaned with extremely aggressive liquids. This cleaning also poses major problems for contemporary doors, which essentially consist of an aluminum alloy. It must be borne in mind that modern railway doors essentially consist of two sheets of aluminum alloy (hereinafter simply "aluminum") which are glued together, have a window in the area of at least one aligned opening, and have a honeycomb or foam core in their interior , further an opening mechanism and the like, and that the metal parts (cover plates outside and inside) are painted.
Diese Türen leiden, trotz der bekannten Passivierung der Oberfläche von Aluminium, unter den korrosiven Waschmedien. Verschiedene Ansätze und Lösungsvorschläge zur Herabsetzung der Korrosion durch Vorbehandlung der verwendeten Bleche auf beiden Seiten, um die besonders unangenehme Korrosion im Türinneren in den Griff zu bekommen, schlugen fehl, entweder weil die Korrosion nicht gehemmt werden konnte oder weil bei der entsprechenden Oberflächenbehandlung ein Verkleben der Bleche nicht mit der notwendigen Festigkeit möglich war.Despite the known passivation of the surface of aluminum, these doors suffer from the corrosive washing media. Various approaches and proposed solutions to reduce corrosion by pretreating the sheet metal used on both sides in order to get a handle on the particularly unpleasant corrosion inside the door failed, either because the corrosion could not be inhibited or because the surface treatment stuck together Sheets were not possible with the necessary strength.
Andere Verbindungsmethoden, wie sie früher verwendet wurden, Verschrauben, Vernie- ten, Verschweißen, kommen wegen der damit verbundenen Kosten und/oder des thermischen Verzuges und/oder der Korrosionsanfälligkeit nicht in Frage, so dass man auf das Kleben angewiesen ist.Other connection methods, such as those used previously, screwing, riveting, welding, are out of the question because of the associated costs and / or the thermal distortion and / or the susceptibility to corrosion, so that one has to rely on the adhesive.
Die Erfindung bezweckt nun einen Türaufbau anzugeben, durch den die genannten Nachteile vermieden oder zumindest wesentlich reduziert werden können. Erfindungsgemäß ist dazu vorgesehen, dass die Lackierung der Bleche zumindest eine Grundierung einer Einbrennlackierung ist, die vor dem Zuschneiden und Verformen der Bleche aufgebracht wurde. Völlig überraschend hat sich gezeigt, dass damit die Vorteile einer Lackierung bzw. zumindest Grundierung im flachen Zustand genutzt werden können, da die Embrennlackierung, anders als anders aufgebrachte Lackschichten, beim Biegen der Bleche nicht absplittern oder auf andere Weise beschädigt werden. Die Embrennlackierung selbst weist wesentlich bessere Resistenz gegenüber den oben erwähnten aggressiven Reinigungsmitteln auf als bisher verwendete Lacke oder Beschichtungen und unterbindet insbesondere die gefürchtete Korrosion aus der Tasche zwischen den Blechen, die speziell von deren unterem Rand ausgeht. Darüberhinaus wird die Verklebung verbessert, die ja auf dem Lack erfolgt und damit sowohl von der Haftfähigkeit des Lackes am Blech als auch von der Fe- stigkeit der Klebung selbst abhängt.The invention now aims to provide a door structure by means of which the disadvantages mentioned can be avoided or at least substantially reduced. According to the invention, it is provided that the coating of the metal sheets is at least a primer of a stoving paint that was applied before the sheets were cut and deformed. Completely surprisingly, it has been shown that the advantages of painting or at least priming in the flat state can be exploited because, unlike paint layers applied differently, the embrane painting does not splinter or be damaged in any other way when the sheets are bent. The Embrennlackierung itself has much better resistance to the above-mentioned aggressive cleaning agents than previously used paints or coatings and in particular prevents the dreaded corrosion from the pocket between the sheets, which starts specifically from the lower edge. In addition, the bond is improved, which is done on the paint and thus depends both on the adhesion of the paint to the sheet and on the strength of the bond itself.
Bleche mit bereits aufgebrachter Einbrennlackierung sind im Stand der Technik bekannt und werden beispielsweise für Verkehrszeichen, Anzeigetafeln, für den Messebau od.dergl. verwendet. Als Beispiel für derartige Bleche kann auf das Produkt SIGNICO- LOR der Alcan Deutschland GmbH, Göttingen, BRD hingewiesen werden. Diese Bleche weisen auf einer Seite, der Außenseite, eine zweischichtige Lackierung auf: Grundierung und Decklack; auf der anderen Seite, der Innenseite, eine Klarlackgrundierung. Dazu kommt, nicht zwingend für die Erfindung notwendig, zum Schutz der Außenseite bei Transport und Lagerung, eine dort aufgebrachte Polyethylenfolie, die bis nach der Verformung des Bleches auf der Oberfläche verbleibt. Es gibt selbstverständlich auch Bleche aus Aluminium mit Einbrennlackierung anderer Herkunft, die ebenfalls verwendet werden können.Sheets with stove enamelling already applied are known in the prior art and are used, for example, for traffic signs, display boards, for trade fair construction or the like. used. As an example of such sheets, reference can be made to the product SIGNICOLOR from Alcan Deutschland GmbH, Goettingen, FRG. These sheets have a two-layer finish on one side, the outside: primer and top coat; on the other side, the inside, a clear coat primer. In addition, not necessarily necessary for the invention, to protect the outside during transport and storage, there is a polyethylene film applied there, which remains on the surface until after the sheet has been deformed. There are of course aluminum sheets with stove enamelling from other origins that can also be used.
Diese Bleche können nach der Kaltverformung, zumeist im gleichen Schritt wie das Ausstanzen des Fensters und anderer Öffnungen (für die Beschläge etc.) und dem eventuell vorgesehenen Umbördeln von Rändern mit allen herkömmlichen Klebstoffen, oder den vom jeweiligen Hersteller genannten, die schon bisher beim Herstellen von Türflügeln verwendet werden, verklebt werden.These sheets can be cold formed, usually in the same step as punching out the window and other openings (for the fittings, etc.) and possibly flanging the edges with all conventional adhesives, or those mentioned by the respective manufacturer, which have already been used in the manufacture used by door leaves can be glued.
Je nach Einsatzgebiet kann die Tasche, die zwischen den beiden Blechen gebildet wird, mehr oder weniger ausgeschäumt, oder mit Waben gefüllt, werden, um die Festigkeit zu erhöhen, die Wärmedämmung zu verbessern und das Schwingungs- bzw. Vibrationsver- halten zu optimieren. Die verschiedenen Bauteile wie Schlösser, Sensoren, elektrische Anschlüsse etc. werden wie üblich eingebaut und fixiert, schließlich wird der Türflügel gelagert oder verschickt oder gleich eingebaut. Es ist nicht wesentlich, dass die Bleche auf einer Seite bereits lackiert und nicht nur grundiert sind, andererseits ist es selbstverständlich möglich, auf beiden Seiten lackierte Bleche zu verwenden bzw. auf beiden (oder auf keiner) Seiten Schutzfolien (aus welchem Material auch immer) aufzubringen.Depending on the area of application, the pocket that is formed between the two sheets can be more or less foamed or filled with honeycombs in order to increase strength, improve thermal insulation and optimize the oscillation or vibration behavior. The various components such as locks, sensors, electrical connections etc. are installed and fixed as usual, after all the door leaf is stored or shipped or installed immediately. It is not essential that the sheets are already painted on one side and not only primed, on the other hand it is of course possible to use coated sheets on both sides or protective films (made of whatever material) on both (or neither) sides. applied.
Wesentlich ist bei allen Variationsmöglichkeiten, die die Erfindung bietet, dass Bleche verwendet werden, die. auf beiden Seiten zumindest mit einer Grundierung aus Einbrennlack versehen sind, bevor sie zugeschnitten, geformt und mit dem Tüflügelrahmen verbunden werden. It is essential with all possible variations that the invention offers that sheets are used that. are provided on both sides with a primer made of stove enamel before they are cut, shaped and connected to the wing frame.
