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, wherein each of which wheels (3) arranged in pairs opposite one another,– with a known wheel diameter (2r, 2rs) is used,– wherein at least on a rail (1) a the wheel (3) which detects the inductively-acting wheel sensor (4a, 4b) below the on the running rail (1) rolling wheels (3) is arranged, which a sensor signal (8a, 8b) generates,– the time difference of the sensor signal (8a, 8b) between the through - and subsequent falling below at least a predetermined threshold value (9) is detected,– on the basis of the wheel speed being a from the time difference of the wheel diameter (2r, 2rs) corresponding chord length (se) is determined, the length of a circle chord in the imaginary wheel diameter circle (rdk) from the auxiliary by means of a predetermined value (hs (i – 1)) of the wheel diameter (2r, 2rs) can be calculated, and– wherein..
