Abstract
Представлено результати статистичних досліджень характеру і параметрів зносу гальмівних колодок в умовах експлуатації, процес утворення й розвитку клиноподібного зношування колодок у взаємодії з колесами, як під час руху без гальмування, так і під час гальмувань. Наведено результати досліджень основних негативних наслідків від ненормативної взаємодії колодок з колесами та висвітлено основні чинники наднормативних матеріальних витрат залізничного транспорту.
The paper analyzed the results of field surveys and feasibility study process, wedge-shaped brake pads wear, which allowed for the first time revealed a number of negative factors, causing serious damage, like railway infrastructure and the environment. Completed studies and assessment of damages on the basis of the research force factors arising in a typical design of the beam brake system of freight wagon bogies and tribotechnical processes due obscene influence of emerging powers. Researched chronology of the formation and development of the wedge-shaped wear pads on the initial stage of occurrence wedge-shaped state, its intensive development and to the final stage. Taken into account the following factors: slope and friction pads on the wheel while driving without braking and braking mode, operating with forces on the shoe, wear from friction and friction heat, which generally lead to a wedge-shaped and wear pads in operation. In this analysis the following negative factors wedge-shaped formation of the state of shoes such as deterioration in braking efficiency of trains; increased costs of energy for traction trains; reduce resource brake pads; high-friction surface character of damage rolling wagon wheels and negative environmental act.
