  • the present invention relates to a sanding device for blowing sand into a gap between a rail and a wheel of a rail vehicle and to a corresponding method for blowing sand into the gap.
  • Sanding systems are used in rail vehicles to improve the adhesion between wheel and rail. To do so, sand is spread on the rail in front of the wheel from a sand container via a pipe or rubber grommet. The outlet of the pipe or rubber grommet from which the sand falls onto the rail is located a few centimeters before the wheel-rail engagement. Air turbulence and air currents running transversely to the vehicle take the sand with it and prevent the sand that is being discharged from landing on the rail. In order to improve the adhesion value between wheel and rail by means of more sand on the rail, the highest possible output speed can be used.
  • the sand is "shot" in front of the wheel via a large air flow and a relatively small dispensing nozzle with the highest possible speed.
