Railed vehicle drive using digital track guidance - uses opto-electric triangulation sensor pair comprising transmitter and receiver using laser measuring beams

摘要

The extended bogie carriage for a track-bound vehicle (1) provides individual suspensions for the running wheels (4a,4b;4a',4b') and digital tracking on at least one of the rails (3a,3b) and at least one guide track. The guide track is followed by at least one opto-electric triangulation sensor pair (5a,5b;5a',5b'), with transmitter and receiver and laser measuring beams, fastened to the vehicle in front of the wheels. The laser measuring beams, when the wheels are running true on the track, are reflected to the receiver which produces a yes pulse and, otherwise, a no pulse. Opposite wheels of the pair to be guided are swivelled according to the sensing process by at least one adjusting motor (6a,6b;6a',6b') towards the correct position, aided by a control unit or microprocessor (10). ADVANTAGE - Improved running characteristics and operational safety.
