Короткий огляд (реферат): The object of research is the brake lever transmission of the 18-100 freight car carriage. The investigated problem: the destruction of the elements of the triangle, which leads to the occurrence of failures during the car operation. As a result of such refusals, total losses for the railway infrastructure of Ukraine during freight transportation amount to hundreds of thousands of hryvnias. The main scientific results: the strength of the brake lever transmission of the freight car carriage is investigated and the most loaded components of its structure are identified. It is proposed to improve the triangle string by making it from a round pipe filled with energy-absorbing material. Aluminum foam is used as an energy-absorbing material. To justify the proposed solution, a calculation of the strength of the brake lever transmission is performed using the finite element method. The calculation results show that the maximum equivalent stresses that occur in the string do not exceed the allowable ones. The peculiarity of the obtained results is that the proposed improvement of triangle elements can be applied not only at the stage of designing the mechanical brake system, that is, during the manufacture of car assemblies at car-building plants. It is advisable to apply the proposed solutions when carrying out depot or capital type repairs at car repair enterprises. The field of practical use of the results is car-building and car-repair enterprises of railway transport of Ukraine. Innovative technological product: the improvement of triangle elements will increase the efficiency of the braking systems of freight rolling stock, increase the speed of cars, reduce the time for the delivery of goods, reduce operating costs due to the failure of freight car units in operating conditions, and guarantee the level of safety of traffic on the railway. Also, the conducted research will contribute to the creation of developments in improving the reliability of the braking systems of modern rolling stock. The scope of application of the innovative technological product: the fleet of freight cars of JSC “Ukrzaliznytsia”, as well as its own industrial transport cars.
