Abstract
In domestic practice, a traditional brake lever transmission (BLT) with one-sided pressing of composite brake shoes on the wheels is used for serial freight cars. It has certain disadvantages. The article notes that recently, work has been carried out on the railway network to improve the transportation process by using innovative freight cars (with an axle load of 25 tf or more and a speed of up to 120 km/h), as well as by introducing so-called long-component trains. In order to ensure traffic safety and standard lengths of braking paths of freight trains with innovative gondola cars, a new layout of the brake lever transmission of a freight car with twosided pressing of brake shoes and one brake cylinder acting on one bogie is proposed, and the values of the lever arms are selected that satisfy the condition of providing the train with braking means. Based on the results of the theoretical and experimental studies, it is clear that the actual braking coefficient of a freight train with innovative cars turned out to be greater than required, therefore, the train is provided with braking means.
