Definitions

  • the invention relates to the construction of rail fastening, for curves of small radii and in particular with a radius of 300 m or less.
  • Known lining fastening type KS from the German description DE 3526653A 1 which consists of a rail fixed to the sleeper with a flange lining of rolled steel.
  • the rail is fastened on two sides by the flanges of the lining on which the rail is mounted, elastic clamping terminals for fixing the rail sole, each of which is mounted on the lining by means of a bolt with washer and nut.
  • the ribbed lining is fixed to the sleepers using four screws.
  • the aim of the invention is the creation of an elastic rail fastening for curves of small radii with increased reliability and durability, by providing elastic movement of the rail sole in the horizontal transverse direction under load.
  • the invention is expressed in the creation of an elastic lining rail fastening for curves of small radii with horizontal elasticity in the transverse direction, when the rail is exposed to horizontal transverse force arising from the passage of the wheel of the rolling stock.
  • An equal in magnitude and opposite in direction direction reaction force appears on the lateral surface of the sole.
  • the elastic fastening elements are deformed, and the rail sole moves in the horizontal transverse direction, which reduces the clearance (a).
  • This reaction determines the elasticity property of the bond in the horizontal transverse direction, according to the essence of the invention.
  • the proposed solution extends the life of wooden sleepers, as there is no contact with steel screws that are screwed into plastic dowels built into the sleepers and the presence of two cones of the flange lining, bearing the action of horizontal load forces.
  • this rail mounting system can be pre-mounted in the workshop or at a sleeper factory. This ensures the accuracy of the location of the nodes on the sleepers, the use of mechanization, reduces the cost of labor and time for installation and dismantling on the way, as the sleepers are supplied with fasteners that are in pre-installation condition, requiring a minimum of manipulation after laying the rails.
  • One of the main advantages of this bond is its low maintenance or even non-maintenance. This means that after mounting the bond does not need any regular maintenance.
  • FIG. 1 Bonding with coil springs - longitudinal section
  • An elastic intermediate fastening with horizontal elasticity in the transverse direction, for curves of small radii the subject of this invention comprises a rail (1) mounted on a wooden rail (2) through a cast iron lining (3), a gasket made of elastic material (4), two elastic terminals (7), two screws (5) screwed into dowels (6), which are built into the sleepers (2).
  • a rail (1) mounted on a wooden rail (2) through a cast iron lining (3), a gasket made of elastic material (4), two elastic terminals (7), two screws (5) screwed into dowels (6), which are built into the sleepers (2).
  • recesses are made for accommodating coil / cup / shaped springs (9) designed to displace the rail sole to the position of contact with the inner flange (11).
