FIELD: transport.
SUBSTANCE: invention relates to railway transport and can be used for control over mounted axle conditions in motion. In compliance with this method, after wheel 9 runs on rail joint 4 circular wave stars propagating over wheel 9 to produce acoustic wave to be emitted therefrom and recorded by converter 1. Said converter converts acoustic wave into electric signal. In the absence of cracks signal duration and frequency will have a definite magnitude. In case there are cracks in said wheel said parameters, that is duration and frequency decrease to indicate inadmissibility of further use of said wheel. Then, wheel 9 rolls on section 5 its length in this case being equal to half the circumference of the wheel whereat acoustic pickups check the section surface for tread quality.
EFFECT: simplified design, better check quality, lower power consumption.
