Resumen
The article presents the results of study of the interaction processes of a brake shoe and a wagon on the level ground and a 30 ? bias during braking operation. The static characteristics of the axial forces, acting upon the brake shoe, as well as their maximum values are defined. It is shown that the car-shoe intercation is characterized by a complex oscillation process of the shoe, containing both low- and high-frequency components of the change of axial effort.
