Definitions

  • the present invention relates to a rail for track-bound vehicles which has no tendency to form corrugations.
  • Ripples are periodic bumps on the rail surface with wavelengths of approx. 30 to 60 mm and amplitudes up to approx. 0.4 mm and are preferably presented on the running surface as more or less regular shiny mountains and valleys. These corrugations reduce driving comfort and contribute significantly to the stress on the vehicles and the superstructure. They cause the track position to deteriorate prematurely and considerably increase noise emissions.
  • Rail made of pearlitic steels with 0.7% carbon and each about 1% manganese and chrome
  • the rail according to the invention which has no tendency to corrugation, is characterized in that it has a metallic material in the area of the running and / or guiding surfaces, the yield or yield strength of which lies above the surface pressure caused by the wheel.
  • the rail does not solidify in the area of the running and / or guide surfaces from a cold-forming process ed material.
  • Suitable filler materials can have the following composition: or
  • the grooved rail according to the invention can be produced in various ways. Electrical cladding has proven to be particularly suitable for producing such a rail.
  • the rail in the area of the running and / or guiding surfaces is mechanically or autogenously cut to a depth of 2 to 3 mm and a width of about 20 to 30 mm, and the recesses are filled with a weld metal of the appropriate composition.
  • the rail head is then machined to fit the profile. It is also possible to apply weld metal without a recess and to grind it so that it can be driven, so that the weld seam protrudes beyond the actual rail profile.
  • the rails according to the invention therefore lend themselves particularly well to the track parts which are particularly stressed and strong corrugations are to be expected.
