SYSTEM FOR MONITORING THE WORKING OF ROTATION OR ROLL DAMPERS

摘要

System for monitoring the working of rotation or roll dampers in rail vehicles provided with a superstructure which rests on at least two chassis, in which the motions which can be generated as a consequence of the self-seeking character of a wheel set are damped in at least one of the chassis by the said rotation or roll dampers which are mounted between chassis and superstructure, on one side each of the chassis. The working of the dampers is monitored by means of suitable sensors, which emit electric signals dependent upon the working of the particular damper. The system is provided with means for comparing the signals of both sensors and for determining a differential signal. The system is further provided with means by which the differential signal is compared with a reference value, which means emit a warning signal if the differential signal exceeds the said reference value.
