Abstract

The vehicle has a shell comprising an underframe, and a support element (2) i.e. clip profile, secured at the underframe by a clip connection i.e. detent connection, for a vehicle floor (1). The clip connection produces a form closure between the support element and the underframe. The support element comprises a rectangular cross-section and a central retaining opening (4) for cooperating with a clip element (5), which projects upward from the underframe. The clip element is designed as an integral component of a cross beam (3) of the underframe.

Description

Die Erfindung bezieht sich auf ein Schienenfahrzeug mit einem Rohbau, der ein Untergestell aufweist, und mit wenigstens einem Auflagerelement für einen Fußboden des Schienenfahrzeugs, wobei das wenigstens eine Auflagerelement an dem Untergestell befestigt ist.The invention relates to a rail vehicle with a shell having a base frame, and with at least one support element for a floor of the rail vehicle, wherein the at least one support element is fixed to the underframe.

Bei einem solchen Schienenfahrzeug werden für die Lagerung von Fußbodenelementen Auflagerelemente benutzt. Diese können aus unterschiedlichen Werkstoffen hergestellt sein und verschiedene Geometrien aufweisen. Ihnen ist gemeinsam, dass sie mit dem Fahrzeugrohbau, insbesondere dessen Untergestell verschraubt, vernietet oder verklebt werden. Sämtliche Befestigungsverfahren erfordern manuell durchzuführende Montagetätigkeiten, welche aufwendig sind.In such a rail vehicle support elements are used for the storage of floor elements. These can be made of different materials and have different geometries. They have in common that they are bolted to the vehicle body shell, in particular its base, riveted or glued. All fastening methods require manually performed assembly activities, which are expensive.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, das Schienenfahrzeug der eingangs genannten Art derart weiterzuentwickeln, dass die Montage der Auflagerelemente für den Fußboden des Schienenfahrzeugs vereinfacht wird.Proceeding from this, the present invention seeks to develop the rail vehicle of the type mentioned in such a way that the mounting of the support elements for the floor of the rail vehicle is simplified.

Diese Aufgabe wird dadurch gelöst, dass das wenigstens eine Auflagerelement über eine Clipsverbindung an dem Untergestell befestigt ist.This object is achieved in that the at least one support element is fastened via a clip connection to the underframe.

Die vorgeschlagene Clipsverbindung zwischen dem Auflagerelement und dem Untergestell bzw. dem Fahrzeugrohbau gestattet eine besonders schnelle Montage der Auflagerelemente, so dass Montagezeit gegenüber dem Stand der Technik eingespart werden kann.The proposed clip connection between the support element and the subframe or the vehicle body allows a particularly fast mounting of the support elements, so that assembly time can be saved over the prior art.

Die Clipsverbindung kann einen Formschluss zwischen dem wenigstens einen Auflagerelement und dem Untergestell herstellen, so dass eine auch im Hinblick auf Ausreißschutz des Fußbodens zuverlässige Verbindung geschaffen wird.The clip connection can produce a positive connection between the at least one support element and the underframe, so that a reliable connection is provided with regard to tear-out protection of the floor.

Das wenigstens eine Auflagerelement kann zentral eine Aufnahmeöffnung zum Zusammenwirken mit einem Clipselement, das vom Untergestell aus nach oben vorsteht, aufweisen.The at least one support element can centrally have a receiving opening for interacting with a clip element which projects upwards from the underframe.

Das Clipselement ist bevorzugt integraler Bestandteil eines Querträgers des Untergestells. Dies bedeutet, dass bereits bei Herstellung des Querträgers, beispielsweise in einem Stranggussverfahren, das Clipselement vorgesehen wird.The clip element is preferably an integral part of a cross member of the undercarriage. This means that already during production of the cross member, for example in a continuous casting process, the clip element is provided.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung noch näher erläutert. Die einzige Figur zeigt eine Querschnittsansicht eines Untergestellbereichs eines Schienenfahrzeugs.An embodiment of the invention will be explained in more detail with reference to the drawings. The single figure shows a cross-sectional view of a sub-frame region of a rail vehicle.

Wie aus der Figur ersichtlich ist, ruht ein Fußboden 1 eines Schienenfahrzeugs auf einem Auflagerelement 2, welches wiederum auf einem Querträger 3 eines Untergestells des Schienenfahrzeugs abgestützt ist.As can be seen from the figure, a floor rests 1 a rail vehicle on a support element 2 , which in turn on a crossbeam 3 a subframe of the rail vehicle is supported.

Das Auflagerelement (Clipsprofil) 2 aus GFK steht in einer Clips(Rast-)verbindung zu dem Querträger 3 und weist dazu zentral eine Aufnahmeöffnung 4 auf, die mit einem Clipselement 5, das integraler Bestandteil des Querträgers 3 ist, zusammenwirkt. Dabei ergibt sich im Bereich der Aufnahmeöffnung 4 ein Formschluss zwischen dem Auflagerelement 2 und dem Querträger 3. Das Clipselement 5 kann z. B. von einem am Untergestell vorhandenen Steg gebildet sein (Aluminiumkonstruktion).The support element (clip profile) 2 made of GRP is in a clip (latching) connection to the cross member 3 and has centrally a receiving opening 4 on that with a clip element 5 , the integral part of the crossbeam 3 is, cooperates. This results in the region of the receiving opening 4 a positive connection between the support element 2 and the cross member 3 , The clip element 5 can z. B. be formed by an existing bridge on the base (aluminum construction).

Das Auflagerelement 2 hat einen rechtwinkligen Querschnitt, wobei von den dem Untergestell zugewandten Ecken aus einwärts Clipsauflageflächen 6 vorgesehen sind, welche die Einhaltung einer gewünschten Position des Auflagerelementes 2 fördern.The support element 2 has a rectangular cross-section, wherein from the sub-frame facing corners of inwardly clip bearing surfaces 6 are provided, which is the maintenance of a desired position of the support element 2 promote.
