Abstract


Results of design researches of brake efficiency of the freight cars with an axial load 25 fon-force with various values of tare weight and a skid margin are cited. Nomographs for choice a gear ratio at change of a skid margin from 0 % up to 10 % are built. Analytical dependences for definition of a gear ratio of the freight car and design factor of brake shoe pressure force on wheels are received. It is shown, that the freight cars with tare weight 25 and 26 tonforce have the greatest brake efficiency.
