The issue of the influence of wear of friction wedges on the wear of the flange thickness of wheel pairs of freight cars operating on the railways of the Republic of Uzbekistan is considered. An analysis of freight car uncouplings during current uncoupling repairs is presented based on malfunctions of the thin flange of the wheel pairs and overestimation/underestimation of the friction wedge relative to the supporting surface of the bolster more than normal. Methods of combinatorial and statistical analysis of source data were used. The parameters of freight car bogies that most influence the wear of the flange of wheel pairs have been studied. Ways to reduce wear on the flange of wheel pairs in operation are considered by tightening the regulatory requirements established when releasing bogies from repair based on the condition of the friction wedges. The results obtained indicate a decrease in wear on the flanges of wheel pairs and an increase in the service life of the wheels of bogies of 18-100 freight cars when following the recommendations of the article on the repair of bogies.
