摘要

A method for calibrating a measuring arrangement for determining of the wheel diameter (2r, 2rs) of longitudinally of two parallel running rails (1) moving wheels (3) of rail vehicles, in particular of a goods waggon, whose respective pairs of wheels (3) are opposite one another,in the case of a known wheel diameter (2r, 2rs) is used as a reference, andin the case of the at least on a rail (1) a the wheel (3) which detects the wheel sensor (4a, 4b) below the on the running rail (1) rolling wheels (3) is arranged, whereby the wheel sensor (4a, 4b) a sensor signal (8a, 8b) generates,characterized by the,that the time difference of the sensor signal (8a, 8b) is provided between the detected by means of - and subsequent falling below, or vice versa, the under - and subsequent exceeding at least a predetermined threshold value (9),that on the basis of the wheel speed a from the time difference of the wheel diameter (2r, 2rs) corresponding chord length (se, ses) is determined,from the auxiliary on the basis of a predetermined value (hs (i – 1), hss (i – 1)) of the wheel diameter (2rv,..
