Abstract
In order to ensure traffic safety and monitor the parameters of the wagons en route, various diagnostic tools for the components are installed when approaching the maintenance depot (PTO). Currently, as part of the implementation of projects to organize the operation of "unmanned stations" on public tracks, equipment for monitoring parts and assemblies of freight wagons (body, chassis, braking equipment) is being placed. The detection of brake equipment malfunctions consists of detecting missing, dragging parts and jamming of wheelsets, for example, if the brake lever gear is incorrectly adjusted. The article considers the issue of using KTSM-03 diagnostic tools to detect increased heating of the wheelsets when the train speed decreases by a specified value within the control. The temperature ranges on the rim of the wheel of a freight car involved in the braking process is determined, depending on all possible ratios of the parameters of the braking equipment that are within acceptable operating limits. The calculated value of the maximum heating of the wheel from pressing the pads to the rolling surface will be the threshold rejection value when monitoring the serviceability of the braking system using KSTM-03 diagnostic tools.
