Purpose and area of application

   The developed system of high-speed regulation of brake pressing of an electric train is intended for increase of efficiency of emergency braking of electric trains due to the more rational use of a factor on coupling wheels with rails. Automatic control of change of pressure in brake cylinders, and, hence, force of block pressing, is carried out under the set program by an electronic regulator of brake pressing (ERBP), which is established on the head car of an electric train.

Technical characteristics

  • number of regulation steps at braking from the maximal speed of 120 km/h - 4-5;
  • maximal pressure of compressed air in the brake cylinders - 0,55 MPa;
  • length of a brake way at emergency braking an electric train from speed of 110 km/h: 400-450 m;
  • weight of the additional equipment on the car - 70 kg;
  • weight of ERBP block - 3 kg;
  • in brake system of an electric train are applied brake blocks from grey iron with the raised contents of phosphorus.
  • average time between failures not less than 5000 hours,
  • average service life  - 5 years.

    • Parameters of safety

    The level of electromagnetic radiation of the device does not harmful influence on the attendants and environment.
