Eddy current or magnetic braking for rail vehicle, uses detector and monitoring program sensing air gap between brake and track to detect unexpected dropping of brake onto track

摘要

The brake is held clear of the rail in normal running of the train, but may fall onto the track if its support is damaged or breaks. The system includes a detector and monitoring program that monitors the distance (h) between the brake (2-7) and the track (1'). One or more distance detectors (11,12) measure the air gaps between the magnetic brake and the track.
