SYSTEM FOR DETECTING DEFECTS IN THE ROUNDNESS OF RAILWAY VEHICLE WHEELS

摘要

The invention relates to a device for assessing the technical condition of the tread of moving railway vehicles, in particular for the automated inspection of the loss of roundness of each wheel of railway vehicles travelling on a track, using a measuring point that generates a signal proportional to the deformation on the rail when a wheel arch passes over the point. Subsequently, a comparator system compares the measured signal with a standard of a wheel with no roundness defects and this is then transmitted over a data network which associates the wheel identification information with wheel defect data generated by the comparator system each time the wheel travels along the measuring zone.
