Abstract
Description
Die Erfindung bezieht sich auf ein Schienenfahrzeug für einen Fahrbetrieb auf Schienenanlagen mit Schotter-Oberbau, welches an seinem Unterboden wenigstens eine nach unten ragende Ausrüstungskomponente aufweist.The The invention relates to a rail vehicle for a Driving on rail systems with ballast track, which on at least one downwardly projecting equipment component having.
Im
Fahrbetrieb solcher Fahrzeuge tritt ein Problem auf, das durch Fachleute
als Schotterwirbel, Schotterflug, Schotterwurf oder Schotterschlag
bezeichnet wird. Das Problem des Schotterfluges ist vor allem bei
Zügen aktuell,
die mit Geschwindigkeiten oberhalb von 200 km/h verkehren. Dieses
Problem ist nachstehend näher
erläutert:
Eine
gebräuchliche
Möglichkeit
der Schwellenbettung ist der Schotter-Oberbau. Beim klassischen Schotter-Oberbau
können
einzelne Schottersteine insbesondere durch Luftströmungen oder
durch abfallende Eisbrocken überfahrender
Züge aus
dem Gleisbett heraus- und hochgeschleudert werden. Nach der Initiierung
werden diese Schottersteine vom Unterflurbereich des Fahrzeuges
getroffen oder treffen umgekehrt das Fahrzeug. Dadurch mögliche Folgen
sind Schäden
am Fahrzeug, speziell an dessen Unterflurbereich und dort angeordneten
Ausrüstungskomponenten,
und auch Schädigungen
der Umwelt durch fliegende Schottersteine. Des Weiteren können die
durch das Fahrzeug nach vorne reflektierten Schottersteine durch
ihre hohe Geschwindigkeit im Gleisbett weitere Steine initiieren
und so eine Schotterlawine hervorrufen.When driving such vehicles, a problem occurs which is referred to by those skilled in the art as ballast, gravel, ballast or ballast. The problem of gravel flight is especially current on trains that operate at speeds above 200 km / h. This problem is explained in more detail below:
A common possibility of Schwellenbetten the gravel superstructure. In classical ballast superstructure, individual ballast stones can be thrown out of the track bed and thrown upwards, in particular by air currents or by falling ice chunks of overcoming trains. After initiation, these ballast stones are hit by the underfloor area of the vehicle or, conversely, hit the vehicle. Possible consequences are damage to the vehicle, especially to its underfloor area and equipment components arranged there, and also damage to the environment by flying ballast stones. Furthermore, the ballast stones reflected forward by the vehicle can initiate further stones due to their high speed in the track bed and thus cause a gravel avalanche.
Die anfliegenden Schottersteine haben nach der Initiierung in Bezug auf das Fahrzeug sehr flache, leicht schräg nach oben verlaufende Flugbahnen. Das Fahrzeug wird daher mit höchster Häufigkeit an den Stellen getroffen, die nach unten aus der Unterbodenebene hinausragen. Die besondere Gefährdung der nach unten herausragenden Ausrüstungskomponenten ergibt sich zusätzlich dadurch, dass die in Fahrtrichtung davor liegenden ebenen Unterbodenabschnitte eine Art Trichterwirkung entfalten und die fliegenden Steine auf die herausragenden Ausrüstungskomponenten zu leiten. Daher wird die Aufgabe der Erfindung insbesondere darin gesehen, auf möglichst einfache Weise die nach unten herausragenden Ausrüstungskomponenten gegenüber anfliegenden Schottersteinen zu schützen und zugleich dafür zu sorgen, dass eine Schotterlawine vermieden wird.The approaching gravel stones have after initiation in relation on the vehicle very flat, slightly obliquely upward trajectories. The Vehicle is therefore with highest frequency hit at the places that are down from the subsoil level protrude. The special danger the downwardly outstanding equipment components result additionally in that the flat underbody sections lying in front of it in the direction of travel a kind of funnel effect unfold and the flying stones on the outstanding equipment components to lead. Therefore, the object of the invention is in particular therein seen, as possible easy way down the outstanding equipment components across from to protect incoming ballast stones while ensuring that that a gravel avalanche is avoided.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass sich in Nähe der Ausrüstungskomponente eine vom Unterboden aus senkecht nach unten ragende Prallplatte befindet, die derart formstabil ausgeführt ist, dass anfliegende Schottersteine an ihr zertrümmert werden.These Task is inventively characterized solved, that is close to the equipment component a baffle plate protruding downwards from the subfloor is, which is designed so dimensionally stable that the approaching ballast stones you smashed become.
Die vom Unterboden aus senkecht nach unten ragende Prallplatte ist für anfliegende Schottersteine exponiert, das heißt, sie wird mit hoher Wahrscheinlichkeit von den Steinen getroffen. Da die Prallplatte vor allem durch ausreichende Blechdicke formstabil ausgebildet ist, werden Schottersteine beim Aufprall auf diese Platte in kleine Einzelteile zertrümmert. Damit ist verhindert, dass die der Prallplatte entgegen der Fahrtrichtung des Schienenfahrzeugs nachgeordnete Ausrüstungskomponente durch anfliegende Schottersteine getroffen und beschädigt wird. Des Weiteren wird durch das Zertrümmern der Schottersteine vorteilhaft eine Schotterlawine vermieden.The from the subsoil from the bottom of the valley downwardly projecting baffle plate is for approaching Gravel stones exposed, that is, they are highly likely hit by the stones. Because the baffle plate especially by adequate Sheet thickness is formed dimensionally stable, gravel stones are on impact smashed into small pieces on this plate. This prevents that the baffle plate counter to the direction of travel of the rail vehicle downstream piece of equipment is hit and damaged by approaching ballast stones. Furthermore, it is advantageous by smashing the ballast stones avoided a gravel avalanche.
