Abstract

Ein Ultraschallsystem zur Abtastung von Rädern von Eisenbahnwagons eines Zuges weist vier Ultraschallsensoren auf, die jeweils einem Rad an einem Drehgestell eines Eisenbahnwagons zugeordnet sind. Außerdem umfasst das Ultraschallsystem eine Anzeigeeinrichtung im Führerstand eines Triebfahrzeugs. Für den Fall, dass einer der Ultraschallsensoren während einer Fahrt des Zuges einen Schaden an dem jeweils zugeordneten Rad des Drehgestells detektiert, wird auf der Anzeigeeinrichtung das Rad, an dem der Schaden detektiert wurde, und der betreffenden Eisenbahnwagon angezeigt und der Zug auf eine Geschwindigkeit von maximal 30 km/h abgebremst. Für den Fall, dass einer der Ultraschallsensoren während eines Stillstands des Zuges einen Schaden an dem jeweils zugeordneten Rad des Drehgestells detektiert, wird ein Öffnen der Bremsen unterbunden.An ultrasound system for scanning wheels of railway wagons of a train has four ultrasonic sensors, each associated with a wheel on a bogie of a railway wagon. In addition, the ultrasound system comprises a display device in the driver's cab of a traction vehicle. In the event that one of the ultrasonic sensors detects a damage to the respective associated wheel of the bogie during a journey of the train, the wheel on which the damage was detected and the railway wagon concerned is displayed on the display device and the train is moved to a speed of braked to a maximum of 30 km / h. In the event that one of the ultrasonic sensors detects a damage to the respective associated wheel of the bogie during a stoppage of the train, an opening of the brakes is prevented.

Description

Das erfindungsgemäße Ultraschallsystem (USS) tastet kontinuierlich den Radreifen ab. Während der Zug steht, wird das ganze Rad auf Schäden abgetastet. Haben sich Mikrorisse im Radreifen gebildet, so lassen sich die Bremsen nicht mehr öffnen.The ultrasound system (USS) according to the invention continuously scans the wheel tire. While the train is stationary, the entire wheel is scanned for damage. If micro-cracks have formed in the wheel tire, the brakes can no longer be opened.

Wenn sich bei einem Zug, z. B. einem ICE, bei hoher Geschwindigkeit ein Mikroriss im Rad gebildet hat, wird dies dem Lokführer auf einem PC angezeigt. Hat sich ein Mikroriss während der Fahrt gebildet, so wird langsam die Luft aus dem Bremskreislauf abgelassen und dadurch der Zug sofort auf max. 30 km/h heruntergebremst. Erreicht der Zug einen Bahnhof, in dem rangiert werden kann, so stoppt der Zug. Die Reisenden steigen nach einer entsprechenden Durchsage im Zug aus dem betroffenen Wagen aus, der mit einer Rangierlok aus dem Zugverband herausgelöst wird. Der Zug kann dann, wenn auch mit Verspätung, weiterfahren.When a train, z. As an ICE, at high speed has formed a micro-crack in the wheel, this is the engine driver displayed on a PC. If a microcrack formed during the journey, the air is slowly released from the brake circuit and thus the train immediately to max. Slowed down 30 km / h. If the train reaches a train station where shunting is possible, the train stops. The passengers get out of the affected car after an announcement in the train, which is released from the train by a shunting locomotive. The train can then proceed, albeit with a delay.

Wird bei der Wartung schlampig gearbeitet, so kann dieser Zug erst gar nicht die Instandhaltungshalle verlassen, da das USS das komplette Rad abtastet und die Bremsen nicht freigeben.If sloppy work is done during maintenance, this train can not leave the maintenance hall at all, as the USS scans the complete wheel and does not release the brakes.

In jedem Drehgestell sitzten 4 USS-Sensoren. Bemerken diese einen Schaden im Rad, so wird vorne im Führerstand der Wagen und das Rad, das einen Riss hat, auf dem PC in ”Rot” markiert und dem Wartungsteam angezeigt. Gegebenenfalls muss das Rad dann ausgewechselt werden.Each bogie contained 4 USS sensors. If they notice a damage in the wheel, the car in the front of the cab and the wheel that has a crack are marked in red and displayed to the maintenance team. If necessary, the wheel must then be replaced.

Künftig sollte es nicht mehr passieren, dass Züge auf freier Strecke entgleisen wegen Schäden an einem Rad.In the future it should no longer happen that trains on the open track derail due to damage to a bike.
