Abstract

The monitoring unit includes pick-ups or sensors to determine the noises and vibrations of the wheels and chassis during the traveling on a railway track and evaluated regarding their frequency spectra. The evaluation is carried out to determine their characteristic features and properties. The frequency spectra and characteristics are compared with those of similar types of chassis and wheel components.

Description

Die Erfindung betrifft eine Einrichtung zur Überwachung der Räder und Fahrge­ stelle an schienengebundenen Fahrzeugen.The invention relates to a device for monitoring the wheels and Fahrge place on rail-bound vehicles.

Es sind bisher keine Einrichtungen bekannt die eine ständige Überwachung der Räder und Fahrgestelle an im Betrieb befindlichen schienengebundenen Fahrzeu­ gen vornehmen.So far, no facilities are known for constant monitoring of the Wheels and chassis on rail-bound vehicles in operation conditions.

Die Erfindung hat es sich zur Aufgabe gemacht diese Nachteile zu vermeiden. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die während der Fahrt an den Rädern und Fahrgestellen der schienengebundenen Fahrzeuge entstehenden akustischen Frequenzspektren hinsichtlich ihrer charakteristischen Eigenfrequenzen durch Meßwertaufnehmer aufgenommen und ausgewertet werden.The invention has set itself the task of avoiding these disadvantages. According to the invention this object is achieved in that the during Ride on the wheels and chassis of the rail-bound vehicles emerging acoustic frequency spectra with regard to their characteristic Natural frequencies recorded and evaluated by transducers become.

Der Vorteil einer solchen Erfindung liegt darin, daß Unregelmäßigkeiten an den Fahrgestellkomponenten durch die Meßwertaufnehmer erkannt werden und eine Warn- oder Alarmfunktion bzw. Notbremsung der schienengebundenen Fahrzeuge eingeleitet werden kann und somit schlimmere Folgeerscheinungen rechtzeitig unterbunden werden können.The advantage of such an invention is that irregularities in the Chassis components are recognized by the transducers and a Warning or alarm function or emergency braking of the rail-bound vehicles can be initiated and thus worse consequences in good time can be prevented.
