turgrenzdifferenzwertes wird ein Alarmsignal ausgelöst und im Anzeigegerät 14 angezeigtan alarm signal is triggered and displayed in the display device 14
Schließlich ist noch ein Zusatzanzeigegerät 16 vorgesehen, welches die Meßwerte jedes Temperaturaufnehmers der Radsatzlager erfaßt und jeden Einzelwert anzeigt, wobei bei Überschreiten eines bestimmten Temperaturgrenzwertes bei mindestens einem Radsatzlager ein Signal ausgelöst wird.Finally, an additional display device 16 is also provided, which shows the measured values of each temperature sensor the wheelset bearings are detected and each individual value is displayed, when a certain temperature limit value is exceeded a signal is triggered in at least one axle box.
Die Überwachungseinrichtung nach der Erfindung enthält für jeden der Temperaturaufnehmer 10 je einen Umschalter 18, der es gestattet, den Temperaturaufnehmer auf eine Heizspannungschiene 17 umzuschalten. Bei Anschaltung an diese wird der Temperaturaufnehmer 10 durch den ihn -durchfließenden Strom erwärmt, und bei einer einzelnen Umschaltung der Umschalter 18 auf das Zusatzanzeigegerät 16 wird die Temperatur angezeigt Jeder Umschalter 18 ist mit einer Einrichtung versehen, durch welche, sobald der Temperaturaufnehmer einen bestimmten Temperaturwert errcxht hat eine Rückschaltung von der Heizspannungschiene 17 auf das Vergleichsgerät 11 und auf das Zusatzanzeigegerät 16 vorgenommen wird. Der jeweils angeschlossene Temperaturaufnehmer wird damit in einer ganz bestimmten Weise aufgeheizt und außerdem wird eine Beschädigung durch eine zu starke Aufheizung verhindert Die Umschaltung erfolgt nach wenigen Sekunden, sobald der Temperaturaufnehmer eine Temperatur erreicht hat, welche merklich über dem Maximalwert liegt. Dieser Wert wird im Zusatzanzeigegerät 16 angezeigt und wirkt zugleich auch im ersten Vergleichsgerät 11 als Maximalwert und löst im zweiten Vergleichsgerät 12 ein Signal aus.The monitoring device according to the invention contains one for each of the temperature sensors 10 Changeover switch 18, which allows the temperature sensor to be switched to a heating voltage rail 17. When connected to this, the temperature sensor 10 is heated by the current flowing through it, and when the switch 18 is switched over to the additional display device 16, the temperature is displayed Each changeover switch 18 is provided with a device through which, as soon as the temperature sensor A downshift from the heating voltage rail 17 has reached a certain temperature value the comparison device 11 and on the additional display device 16 is made. The respectively connected The temperature sensor is heated up in a very specific way and it is also damaged prevented by excessive heating. The switchover takes place after a few seconds as soon as the temperature sensor has reached a temperature which is noticeably above the maximum value. This value is displayed in the additional display device 16 and at the same time also acts in the first comparison device 11 as Maximum value and triggers a signal in the second comparison device 12.
Diese Prüfung kann bei Stillstand des Fahrzeugs von Hand erfolgen. Die Anzeige im Vergleichsgerät 12 bzw. im Anzeigegerät 14 ist ein Indiz für die Funktionsfähigkeit von Temperaturaufnehmer, Verbindungsleitungen sowie der Vergleichsgeräte 12 und 13.This check can be carried out manually when the vehicle is stationary. The display in the comparison device 12 or in the display device 14 is an indication of the functionality of the temperature sensor, connecting lines as well as the comparison devices 12 and 13.
