Abstract

The vehicle has a downwardly projecting fitting component (2) at an under body (1) of the vehicle. A firm plate (3) is attached near the fitting component, and is projected downwardly to the under body of the vehicle. The firm plate is conducted in a dimensionally stable manner so as to break down approaching ballast pebbles (4), where the firm plate is fastened to the under body of the vehicle.

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.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments of the invention are specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung prinzipartig dargestellt und wird im Weiteren näher beschrieben. Die Zeichnung zeigt einen Abschnitt des Bodenbereichs eines Schienenfahrzeugs in Seitenansicht.One embodiment the invention is shown in principle in the drawing and will be closer in the following described. The drawing shows a section of the floor area a rail vehicle in side view.

Das Schienenfahrzeug weist an seinem Unterboden 1 wenigstens eine nach unten ragende Ausrüstungskomponente 2 auf. Entgegen der Fahrtrichtung 5 gesehen befindet sich in Nähe der Ausrüstungskomponente 2 eine vom Unterboden 1 aus senkecht nach unten ragende Prallplatte 3. Diese Prallplatte 3 ist insbesondere durch ausreichende Blechdicke derart formstabil ausgeführt, dass anfliegende Schottersteine 4 an ihr zertrümmert werden. Die Prallplatte 3 kann am Unterboden 1 befestigt oder an der Ausrüstungskomponente 2 angebracht sein. Es empfiehlt sich, die Prallplatte 3 an ihrer anfliegenden Schottersteinen 4 zugewandten Seite mit Unebenheiten zu versehen, die einem Abrutschen der zu zertrümmernden Schottersteine 4 entgegenwirken.The rail vehicle points to its underbody 1 at least one down-facing equipment component 2 on. Against the driving direction 5 Seen near the equipment component 2 one from the underbody 1 out of the valley, downwardly projecting baffle plate 3 , This flapper 3 is designed in particular dimensionally stable by sufficient sheet thickness that approaching ballast stones 4 to be smashed to her. The flapper 3 can be on the underbody 1 attached or attached to the equipment component 2 to be appropriate. It is recommended the baffle plate 3 on their approaching ballast stones 4 facing side to provide bumps, a slipping of the crushed gravel stones 4 counteract.
