Abstract (English):
It is wellknown that at long braking and parking of a train or a single railroad car the air pressure in brake cylinders and control reservoirs gradually drops because of air leaks that results in exhaustion of brake as a consequence of this a rollingstock can start spontaneous motion which can cause severe damages and accidents. It is a substantial drawback in an indirectacting automatic brake. To eliminate such a drawback there was developed a promising brake design at the level of an invention in Bunin ESU and a set of computations for the substantiation of rational parameters for a springing element excluding the cessation of brake functioning and hence a possibility for spontaneous rollingstock motion.
