Abstract

The invention relates to an arrangement for improving the load-bearing capacity of a rail vehicle (SFZ). The rail vehicle (SFZ) comprises a carriage body (WK) having a first connection point (ASP1) and a second connection point (ASP2). The two connection points (ASP1, ASP2) are connected to one another via a clamping element (SPE). The clamping element (SPE) is pre-tensioned in such a way that a bending of the carriage body (WK) is reduced.

Anordnung zur Verbesserung der Belastbarkeit eines Schienen fahrzeugs Arrangement to improve the resilience of a rail vehicle
Die Erfindung betrifft eine Anordnung zur Verbesserung der Belastbarkeit eines Schienenfahrzeugs. The invention relates to an arrangement for improving the loading capacity of a rail vehicle.
Ein Wagenkasten eines Schienenfahrzeugs darf im beladenen Zu stand nur eine gewisse Durchbiegung aufweisen. A car body of a rail vehicle may only have a certain amount of deflection when it is loaded.
Als Wagenkasten wird ein Aufbau eines Eisenbahnwagens, ei nes Triebwagens oder einer Lokomotive bezeichnet. Ein Wagen kasten kann auf einem Rahmen aufgebaut oder selbsttragend ausgeführt sein. A body of a railroad car, a railcar or a locomotive is referred to as a car body. A car box can be built on a frame or designed to be self-supporting.
Um eine geforderte Begrenzung der Durchbiegung des Wagenkas tens zu erreichen, wird die Struktur des Wagenkastens ent sprechen gestaltet bzw. konstruiert. In order to achieve the required limitation of the deflection of the car body, the structure of the car body is designed or constructed accordingly.
Dies resultiert oft in einer Bauweise des Wagenkastens, die mechanisch entsprechend dimensioniert bzw. vom verwendeten Material her massiv ausgestaltet ist. This often results in a construction of the car body which is mechanically dimensioned accordingly or which is massive in terms of the material used.
Dies führt zu Gewichtsproblemen, zugleich begrenzen weitere konstruktive Vorgaben eine sinnvolle Ausgestaltung des Wagen kastens . This leads to weight problems, at the same time limit further structural requirements a meaningful design of the car body.
Es ist die Aufgabe der vorliegenden Erfindung, eine Anordnung zur Verbesserung der Belastbarkeit eines Schienenfahrzeugs anzugeben, mit der die oben genannten Probleme mit Blick auf das Gewicht und mit Blick auf die bisherige massive Ausge staltung reduziert werden. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprü chen angegeben. It is the object of the present invention to provide an arrangement for improving the load-bearing capacity of a rail vehicle, with which the above-mentioned problems with a view to the weight and with a view to the previous massive design are reduced. This object is achieved by the features of claim 1. Advantageous developments are given in the dependent claims.
Die Erfindung betrifft eine Anordnung zur Verbesserung der Belastbarkeit eines Schienenfahrzeugs. The invention relates to an arrangement for improving the loading capacity of a rail vehicle.
Das Schienenfahrzeug weist einen Wagenkasten auf. Der Wagen kasten weist einen ersten Anschlusspunkt und einen zweiten Anschlusspunkt auf, die über ein Spannelement miteinander verbunden sind. The rail vehicle has a car body. The car body has a first connection point and a second connection point, which are connected to one another via a clamping element.
Das Spannelement ist dabei derart vorgespannt, dass eine Durchbiegung des Wagenkastens reduziert wird. The tensioning element is pretensioned in such a way that bending of the car body is reduced.
Durch den Einsatz des Spannelements wird der Wagenkasten vor gespannt. Die Vorspannung wird dabei so gewählt, dass der Wa genkasten im unbeladenen Zustand eine negative Durchbiegung aufweist. Durch die negative Durchbiegung wird eine über die Beladung des Wagenkastens gebildete positive Durchbiegung re duziert bzw. vollständig kompensiert. The car body is pre-tensioned by using the tensioning element. The preload is chosen so that the car body exhibits negative deflection when it is unloaded. Due to the negative deflection, a positive deflection formed by the loading of the car body is reduced or completely compensated for.
In einer bevorzugten Ausgestaltung werden als erster und als zweiter Anschlusspunkt des Wagenkastens diejenigen Anschluss punkte verwendet, über die Druck- und Zugkräfte auf den Wa genkasten wirken. In a preferred embodiment, those connection points are used as the first and second connection point of the car body via which pressure and tensile forces act on the car body.
Beispielsweise handelt es sich hierbei um eine Kombination aus Zughaken und Puffern oder um Kupplungen des Schienenfahr zeugs, die am Wagenkasten angebracht sind. For example, this is a combination of draw hooks and buffers or couplings of the rail vehicle that are attached to the car body.
In einer bevorzugten Ausgestaltung ist das Spannelement ein Seil, das bevorzugt als Kevlar- oder als Kohlefaser-Seil aus gebildet ist. In einer bevorzugten Ausgestaltung wird die Vorspannung nach der Montage bzw. nach erfolgter Fertigung des Wagenkastens durch das Spannen des Spannelements aufgebracht. In a preferred embodiment, the tensioning element is a rope, which is preferably formed as a Kevlar or carbon fiber rope. In a preferred embodiment, the pre-tensioning is applied by tensioning the tensioning element after assembly or after the car body has been manufactured.
In einer bevorzugten Ausgestaltung ist das Spannelement in Trägern des Wagenkastens angeordnet bzw. darin geführt. In a preferred embodiment, the tensioning element is arranged or guided in supports of the car body.
Durch die vorliegende Erfindung wird eine vereinfachte Ferti gung des Wagenkastens ermöglicht. Die Vorspannung des Spann elements wird kontrolliert nach dem Verbinden der Wagenkas tenkomponenten aufgebracht. The present invention enables a simplified production of the car body. The pre-tensioning of the clamping element is applied in a controlled manner after the car body components have been connected.
Durch die vorliegende Erfindung wird beim Wagenkasten die Aufnahme erhöhter Nutzlasten ermöglicht. The present invention enables the car body to accommodate increased payloads.
Durch die vorliegende Erfindung wird ein Wagenkasten reali sierbar, der bei leichterem Gewicht belastbarer ist, als es eine bekannte Wagenkasten-Konstruktion wäre. The present invention enables a car body to be realized which is more resilient with a lighter weight than would be a known car body construction.
Nachfolgend wird die vorliegende Erfindung beispielhaft an hand einer Zeichnung näher erläutert. Dabei zeigt: The present invention is explained in more detail below using a drawing, by way of example. It shows:
FIG 1 die Erfindung anhand eines Wagenkastens WK eines Schie nenfahrzeugs SFZ. 1 shows the invention using a car body WK of a rail vehicle SFZ.

The car body WK has a first connection point ASP1 and a second connection point ASP2, which are connected to one another via a clamping element SPE.
Das Spannelement SPE ist dabei derart vorgespannt, dass eine Durchbiegung DURCHB des Wagenkastens WK durch die Vorspannung VORSP reduziert wird. Durch den Einsatz des Spannelements SPE wird der Wagenkasten WK vorgespannt. Die Vorspannung VORSP wird dabei so gewählt, dass beim Wagenkasten WK die über die Beladung des Wagenkas tens WK gebildete Durchbiegung DURCHB reduziert bzw. voll- ständig kompensiert wird. The tensioning element SPE is pretensioned in such a way that a deflection DURCHB of the car body WK is reduced by the pretensioning VORSP. The car body WK is pretensioned by using the SPE clamping element. The preload VORSP is selected in such a way that in the car body WK the deflection DURCHB formed by the loading of the car body WK is reduced or completely compensated for.
In einer bevorzugten Ausgestaltung werden als erster An schlusspunkt ASP1 und als zweiter Anschlusspunkt ASP2 des Wa genkastens WK diejenigen Anschlusspunkte verwendet, über die Druck- und Zugkräfte F auf den Wagenkasten WK wirken.
