Abstract

Die Erfindung betrifft eine Einrichtung zum Überwachen des Zustands einer Wirbelstrombremse an einem Schienenfahrzeug mit einem der Schiene (1) zugewandten Bremskörper, der am Schienenfahrzeug über einen Isolierkörper gehalten ist und zur Erdung über ein Erdkabel (12) mit einem Schienenrad (2) des Schienenfahrzeugs in Verbindung steht. Es ist vorgesehen, dass das Erkabel (12) mit einem Strommesser (14) in Verbindung steht, dem eine Auswerteeinheit (8) nachgeschaltet ist. Dort wird aus einer erhöhten Stromstärke auf eine Beschädigung der Isolierung bzw. auf ein Aufsetzen des Bremskörpers auf die Schiene (1) geschlossen.

Figure 00000001
The invention relates to a device for monitoring the state of an eddy current brake on a rail vehicle with a brake body facing the rail (1), which is held on the rail vehicle via an insulating body and for grounding via an underground cable (12) with a rail wheel (2) of the rail vehicle in Connection is established. It is provided that the detection cable (12) is connected to an ammeter (14) which is followed by an evaluation unit (8). There, an increased current intensity indicates damage to the insulation or that the brake body is placed on the rail (1).
