Definitions

  • the invention relates to an escapement for railway carriages, which is provided with a sole plate, which ends in an overrun tongue and a bracket provided with an overlay plate for a wheel to be braked, and with a handle, the escapement at least partially, but preferably for Whole, consists of a cast iron material.
  • the inhibitor currently in use in Austria, but also in other countries, consists of a plurality of forged or rolled parts, which are riveted together with the exception of the ramp plate provided on an exchangeable brake flap.
  • This proposal has not found its way into practice, since the production of a single-use part made of cast steel after partial wear and tear for scrap is uneconomical.
  • the cost of such a cast body is so high that it is cheaper to buy a conventional forged brake shoe and replace it with partial wear and tear, for example by welding a new overrun tongue or replacing the brake flap.
  • the trestle carrying the casserole plate In order to cool the trestle carrying the casserole plate, it can also be provided with ribs projecting to the side.
  • the escapement according to the invention consists in the usual way of a sole plate 1, which has a run-on tongue 2 at its front end, which ends in a run-up wedge 3.
  • the sole plate 1 is provided with side flanges 4, which ensure the alignment of the inhibitor on the rail.
  • the sole plate 1 carries a trestle 5, on which the ramp plate 6 for the wheel to be braked is arranged.
  • the ramp plate 6 is an integral part of the brake shoe, but it would also be possible to arrange it in a customary manner in an exchangeable brake flap without deviating from the inventive concept.
  • the inhibitor shown consists entirely of cast iron with spheroidal graphite, for example GGG (400). Ductile iron grades alloyed with silicon and molybdenum have also proven themselves in the test. Because of the reduced thermal conductivity of such a material compared to steel, various measures have been taken in the illustrated restraint shoe in order to ensure a uniform distribution and good dissipation of the heat.
  • the web 8 ensures that the load of the vehicle wheel standing on the ramp tongue 2 and resting on the ramp plate 6 is evenly distributed on the underside of the sole plate 1, so that there is no local overheating and material accumulation. The heating of the ramp plate 6 can be reduced if sliding friction between this part and the vehicle wheel is maintained for as long as possible.
  • a transverse groove 11 is provided, which is filled with a solid lubricant, namely with graphite, which is held together by a binder.
  • a groove can also be provided on the top of the overrun tongue 2.
  • Ribs 7 contribute to the faster dissipation of the heat to the environment, which also serve for the uniform introduction of the forces exerted on the ramp plate 6 into the sole plate 1.
  • the inhibitor shown is placed in the usual way by the operating personnel in the way of a rolling railway wagon, the reduced weight making handling easier.
  • a wheel of the car now runs over the ramp wedge 3 until it strikes the ramp plate 6, whereupon the wheel slides on the ramp tongue 2 and the ramp plate 6, while the entire shoe is moved on the rail. It has now turned out to be important that the rotational movement of the wheel is maintained as far as possible until the brake shoe comes to a standstill, that is to say that kinetic energy is destroyed for as long as possible both on the underside of the soleplate 1 and on the top of the ramp tongue 2 and ramp plate 6.
