RAILROAD VEHICLE FOR MEASURING THE GEOMETRICAL PARAMETERS OF RAILROAD TRACK

摘要

The invention relates to a railroad vehicle for measuring the parameters of a railroad track, characterized by the presence of third axles (13 and 23) with independent wheels and disposed between the main axles (11 and 12; 21 and 22) of the bogies (10 and 20) of the vehicle, and by the existence of a third bogie (30) having two axles (31 and 32) capable of undergoing relative angular displacement about a line passing through their centers, said third bogie (30) also having a third axle (39) with having independent wheels; the measurements are made by means of optical proximity meters and distance gauges.
