摘要

A process for the determination of the track ring by knife (2rs) of longitudinally of two parallel running rails (1) moving wheels (3) of rail vehicles, in particular of a goods waggon, wherein the wheels (3) are in each case arranged in pairs and opposite to one another,on the running rail (1) below the on the running rail (1) rolling wheels (3) two the wheel (3) detecting wheel sensors (4a, 4b) are arranged, which in the case of a further rolling wheel (3) in each case a sensor signal (8a, 8b) generating, the temporal course of in each case at the beginning continuously increases or decreases and at the end that is, in turn increases or decreases steadily,characterized by the,that on each side of the running rail (1) one of the wheel sensors (4a, 4b) is arranged, the form of a surface of a circle of rotation of - wheel sensor below of the orbit (5) and the other as a flange - wheel sensor below the wheel flange (6), that for each sensor signal (8a, 8b) in each case the time difference between the through - and subsequent falling below or the under - and subsequent at least a predetermined threshold value is exceeded..
