Definitions

  • the invention relates to a track brake for rail vehicles with at least one distributed over the length arranged brake segments populated brake beam, which can be pressed with the braking surfaces of its brake segments laterally to a flank of the rail wheel.
  • Track brakes of this type are known see eg GB-A-1 482 999 , They can be arranged on one or both sides of the track.
  • the pressure acting on the brake bar pressing force can be done mechanically by rubber spring packages or by hydraulic or pneumatic cylinder.
  • it is a well-known phenomenon that caused by mechanical friction between the brake beam and the edge of the rail wheel squeaking noise, which are perceived by nearby people as disturbing.
  • brake segments of a length between 0.4 and 1.2 m are provided in the known track brake with a small distance from each other, which are fastened with damping intermediate layers on the brake beam.
  • the brake segments are no longer made of steel, but are manufactured as a cast segment of nodular graphite.
  • the reduction of screeching noise achieved with such a track brake is not perceived as sufficient.
  • the invention has for its object to provide a rail brake for rail vehicles with improved damping of the squeaking noise generated during braking.
  • This object is achieved in a track brake of the type mentioned above in that the braking surfaces of the successive in the direction of travel brake segments are arranged at different heights.
  • the brake segments as known per se, interchangeable mounted on the brake beam. So they can be replaced after wear.
  • the brake segments are formed by the same bases and associated and arranged at different heights straps on which the braking surfaces are formed.
  • various brake segments can be easily fastened by bolts, since an arrangement of holes in different heights is not required. This is also advantageous for the conversion and retrofitting.
  • a damping insert can be provided between the brake segments and the brake beam.
  • FIG. 1 is on a threshold 1 of a track bed 2, a rail 3 attached. On the rail 3 runs a rail wheel 4, against whose flank 4 a, a brake bar 5 a track brake is pressed.
  • the known pressing means are not shown here.
  • FIGS. 2 to 5 show, made of a cast or rolled steel U-profile brake beam 6 with a plurality of distributed over its length arranged brake segments 7, 8, 9, 10, 11, 12 equipped.
  • the brake segments 7 to 12 are bolted to the brake beam 6 using an intermediate layer 13 of damping material by means of bolts 14, 15.
  • Each brake segment 7 - 12 is a forged or cast molded body made of steel or preferably a cast body made of nodular graphite. It is formed by a gleichformatigen base 7 a, 9 a and a so integrally connected raised carrier 7 b, 9 b, on which a braking surface 7 c, 9 c is formed.
  • the carrier 7 b of the brake segments 7, 8, 11, 12 are set high in the first type
  • the carrier 9 b in the second type of brake segments 9, 10 set lower.
  • the length of each successively arranged at the same height segments is 0.5 to 1.5 m.
  • the height displacement of the elements is approximately equal to their width and is 40 to 60 mm.
