Abstract

The invention relates to a railway vehicle with a self-supporting car body having a floor and a roof as well as side walls which present windows and access areas. The side walls are each made of a frame which is rigidly connected to the floor and presents side wall elements. The car body skin elements are configured in a supporting manner and fixed to frame elements (2) by friction so as to form a ribbed plate support structure (1, 8). The car body skin elements comprise an integrated intermediate layer (5) having vibration-damping properties. Frictional adhesive joints (7) or frictional screw or rivet joints (9) between the frame elements (2) and supporting car body skin elements can be provided for. The supporting car body skin elements are configured as supporting sandwich elements (3) which consist of an outer layer (4), an inner layer (6) and an intermediate layer (5) which has heat- and/or sound-insulating and vibration-damping properties and maintains the outer and inner layer at a distance from each other.

Description

Die Erfindung bezieht sich auf ein Schienenfahrzeug mit einem selbsttragenden Wagenkasten mit einem Boden und einem Dach sowie mit Seitenwänden, welche Fenster und Einstiegsbereiche aufweisen, wobei die oberhalb des Bodens befindlichen Wagenkastenstrukurelemente von einem mit den Boden biegesteif verbundenen Rahmen mit daran angebrachten Seitenwand- bzw. Dachelementen oder dergleichen gebildet sind, wobei die Wagenkastenhautelemenete tragend ausgebildet und zur Bildung eines verrippten Plattenwerkes definiert mittragend an Rahmenelementen befestigt sind und die Wagenkastenhautelemente eine integrierte Zwischenschicht aufweisen.The invention relates to a rail vehicle with a self-supporting Car body with a floor and a roof and with side walls, which windows and have entry areas, those located above the floor Car body structure elements from a frame rigidly connected to the floor are formed with attached side wall or roof elements or the like, the car body skin elements designed to be load-bearing and to form a ribbed panel works are attached to the frame elements and the Car body skin elements have an integrated intermediate layer.

Aus der EP 0 474 510 A1 ist ein derartiges Schienenfahrzeug bekannt. Die Wagenkastenhautelemente sind in ihrem Inneren mit wabenförmigen Metallstrukturen ausgefüllt. Sie ermöglichen eine Stützwirkung dieser Sandwichelemente zur Erfüllung der statischen Erfordernisse. Einen Hinweis auf eine gleichzeitig definiert schwingungsdämpfende Ausbildung solcher Schienenfahrzeuge gibt die EP 0 474 510 A1 indessen nicht.Such a rail vehicle is known from EP 0 474 510 A1. The Car body skin elements are in their interior with honeycomb-shaped metal structures filled. They enable these sandwich elements to have a supporting effect the static requirements. An indication of one being defined at the same time Vibration-damping design of such rail vehicles is given by EP 0 474 510 A1 however not.

Aus der DE 195 12 629 A1 ist ein Schienenfahrzeug bekannt. Dessen Seitenwandelemente steif (nicht schwingungsdämpfend) ausgebildet und am Fachwerk mittels Klebeverbindung nichttragend befestigt, wobei die Klebeverbindung zur Schwingungsdämpfung von beim Betrieb des Schienenfahrzeuges auftretenden Schwingungen dient. Die Klebung muß eine ausreichende Schichtdicke aufweisen, um die zur Absorption der Schwingungen eingeplante Dämpfüngsarbeit zu leisten. Dabei wird ausgeführt, daß eine zu dünne Klebeschicht zu keiner Dämpfung sonder zu Steifigkeit der Konstruktion führen würde, was andere Maßnahmen zur Beherrschung der störenden Schwingungen erfordern würde und nur mit entsprechend festigkeitsmäßig als tragend ausgelegten Seitenwandelementen realisierbar wäre. A rail vehicle is known from DE 195 12 629 A1. Whose Sidewall elements rigid (not vibration-damping) and on the truss attached non-load-bearing by means of an adhesive connection, the adhesive connection for Vibration damping of those occurring during the operation of the rail vehicle Vibrations. The bond must have a sufficient layer thickness in order to to perform the damping work planned to absorb the vibrations. there it is stated that a too thin adhesive layer does not cause any damping Rigidity of the construction would result in other measures to control which would require disruptive vibrations and only with appropriate strength would be realizable as load-bearing side wall elements.

Der Erfindung liegt die Aufgabe zugrunde, ein besonders leichtes Schienenfahrzeug mit einem selbsttragenden Wagenkasten Art anzugeben, welches nicht nur den statischen Erfordernissen genügt, sondern darüber hinaus noch die Möglichkeit bietet, daß Fahrzeug definiert schwingungsgedämpft auszubilden.The invention is based, with a particularly light rail vehicle with the task to specify a self-supporting car body type, which not only the static Sufficient requirements, but also offers the possibility that Vehicle defined to be vibration-damped.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 dadurch gelöst, daß die integrierte Zwischenschicht definiert schwingungsdämpfende Eigenschaften aufweist. This task is done in conjunction with the features of the preamble of the claim 1 solved in that the integrated intermediate layer defines vibration damping Has properties.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die Rahmenelemente des erfindungsgemäß ausgebildeten Schienenfahrzeuges leichter und geringer (schlanker) dimensioniert gestaltet werden können als beim bekannten Fall. Da die Wagenkastenhautelemente selbst als tragende Baukomponenten ausgeführt sind, übernehmen sie einen Teil der Tragefunktion des Fachwerkes. Insgesamt gelangt man zu einem gewichtsreduziertem und damit kostengünstigen Wagenkasten. Von großer Wichtigkeit sind dabei die als Klebe- oder Schraub- oder Nietverbindungen ausgeführten kraftschlüssigen Befestigungen zwischen Wagenkastenhautelementen und Rahmenelementen. Die Dämpfung von beim Betrieb des Schienenfahrzeuges auftretenden störenden Schwingungen (Biegeeigenschwingungen) erfolgt in ausreichendem Maße durch eine entsprechend gestaltete Zwischenschicht in den vorzugsweise in Form von Sandwichelementen ausgeführten Wagenkastenhautelementen. Es ist ein hohes Maß an Fahrkomfort über den gesamten angeregten Frequenzbereich gewährleistet.The advantages that can be achieved with the invention are, in particular, that the Frame elements of the rail vehicle designed according to the invention lighter and can be made smaller (slimmer) dimensioned than in the known case. Since the Body elements are designed as load-bearing components themselves they are part of the supporting function of the framework. Overall you get to one weight-reduced and therefore inexpensive car body. Are of great importance the non-positive connections designed as adhesive or screw or rivet connections Fastening between body panels and frame elements. The damping of disturbing vibrations occurring during the operation of the rail vehicle (Bending natural vibrations) takes place to a sufficient extent by a correspondingly designed Intermediate layer in the preferably in the form of sandwich elements Car body skin elements. It is a high level of driving comfort across the board excited frequency range guaranteed.
