Definitions

  • the invention relates to an angle guide plate for the attachment of rails for rail vehicles, which is equipped with a bearing surface over which the angle guide plate is placed in its mounting position on a solid surface.
  • the invention relates to a system for fastening a rail for rail vehicles, comprising an attachable with a support surface on a substrate angle guide plate on which a mounting element in the mounting position, a spring element for applying the required holding force is supported on the rail.
  • Such angle guide plates and fastening systems are, in many variants known (see for example http:. '//Www.vossloh-rail-systems.de/ or DE-AS 1,954,008, EP 0,231,304 Bl, DE 33 34 119 Al).
  • the purpose of the angled guide plates is to support the required elastic holding force on the rail foot performing spring element in the assembled state.
  • the angled guide plate is a lateral support of the rail foot, by which the rail is held in the respective prescribed longitudinal orientation. This requires a firm, precisely aligned seat of the angled guide plate on the respective substrate.
  • the well-known angle guide plates and the fastening systems equipped with them have proven themselves in operation. However, under certain operating conditions increased wear in the region of the support surface has been found, with which the angle surface is supported on the support of the overall support rail with the base. This wear manifests itself in a removal of material on the support surface angle plate and / or the support surface of the substrate on which the angle plate rests.
  • the object of the invention therefore was to provide an angled guide plate in which the risk of abrasive wear in the region of its bearing surface is minimized.
  • a system for fastening rails was to be created in which the risk of the formation of abrasive wear in the angled guide plate is reduced to a minimum with simple means even under unfavorable operating conditions.
  • this object is achieved in that the bearing surface is at least partially occupied by an elastic layer.
  • An angle guide plate according to the invention has in the region of its support surface on an elastic layer over which it rests in its mounting position on the support surface of the angled guide plate supporting ground.
  • This elastic layer also prevents the gaping of a gap between the bearing surface of the angled guide plate and the support surface of the ground when passing the rail, the angle guide plate due to the weight of the rail vehicle and the associated dynamic movement of the rail, the angle guide plate in the horizontal or vertical direction relative to Underground is moved.
  • the penetration of particles into the critical area between angle guide plate and substrate can thus be permanently prevented.
  • the elastic layer dampens the effect of such particles, which, despite the seal provided by the invention, reach the area between the angled guide plate and the substrate.
  • the invention thus minimizes the abrasive wear of the angled guide plate or substrate in the prior art.
  • a spring element for applying the required holding force on the rail the above object is achieved in that it comprises an elastic layer for insertion between the bearing surface of the angled guide plate and the solid ground.
  • a thin elastic layer whose thickness is substantially less than the thickness of the angled guide plate in the region of the support surface.
  • the thickness of the elastic layer can be limited to at most 10% of the average thickness of the angled guide plate in the region of the support surface. Due to the fact that the elastic layer has no spring function, it is also preferably designed so that it is compressed as much as possible in the assembly forces acting on the angle guide plate in its mounting position. This results in a particularly good effect of the elastic layer when it is completely or at least almost completely compressed with ready mounted angle guide plate
  • the support surface of the angled guide plate is occupied in the areas with the elastic layer in which gaps can form in practical operation between the support surface and the support surface.
  • a particularly secure transmission of the forces acting on the angled guide plate during assembly and during operation can be achieved if the elastic layer covers the contact surface over its entire area.
  • Suitable materials for the elastic layer are all materials whose elasticity is retained even after prolonged compression. Accordingly, the elastic layer is preferably made of a polyurethane, a rubber, a rubber or other elastomeric material. These materials are available at low cost and expand sufficiently quickly even with a short-term gap formation between angled guide plate and substrate to avoid the penetration of particles such as dust or sand in the critical area.
  • the elastic layer can be firmly connected to the angled guide plate. This can be achieved for example by suitable mold elements, etc., which hold the elastic layer positively and / or non-positively on the angled guide plate.
  • the elastic layer is bonded in a material-locking manner, for example by gluing or vulcanization, to the bearing surface of the angled guide plate.
  • a cohesive connection between the elastic layer and angled guide plate is additionally prevented that particles get into the area between the elastic layer and the support surface and cause wear there.
  • the invention can be used in such systems in which the rails are mounted on a threshold, which forms the solid surface for the angled guide plate.
  • a threshold which forms the solid surface for the angled guide plate.
  • the threshold is made of a concrete material.
  • concrete sleepers or comparable thresholds made especially sensitive to abrasive materials produced thresholds show the advantages achieved by the inventive arrangement of an elastic layer between the angled guide plate and threshold.
  • FIG. 1 shows a system for fastening a rail for a rail vehicle in longitudinal section.
  • Fig. 2 is an angle guide plate in a view from below.
  • the system 1 is used for fastening a rail 2, of which in Fig. 1, only the system 1 facing edge of the rail foot is shown. It comprises a concrete sleeper 3, an angled guide plate 4, an elastic layer 5, as a spring element for generating the required holding force, a tensioning clamp 6 and a tensioning screw 7 for tensioning the tensioning clamp 6.
  • the concrete sleeper 3 comprises a flat support surface 8, in which a groove 9 is formed in the region of its lateral end.
  • the adjacent to the groove 9 side end portion of the support surface 8 forms the area on which the angle guide plate 4 is in mounting position.
  • a recess is formed in this end, in which a plastic dowel 10 is seated for the clamping screw 7.
  • the angle guide plate 4 which is formed in a manner known per se, has, on its upper side, form elements 11 which guide the tensioning clamp 6 in its mounting position and ensure the secure transmission of the holding forces to the rail foot of the rail 2.
  • a through hole 12 is additionally formed in the angled guide plate 4, by the clamping screw 7 in the assembly in itself also known manner Clamping the tension clamp 6 is guided to screw them into the plastic dowel 10 of the threshold 3.
  • a flat bearing surface 13 is formed, which is bounded at its in the mounting position facing away from the rail 2 edge by a longitudinally extending edge 14 of this.
  • the elevation 14 additionally carries projections 15 whose cross-sectional shape is adapted to the cross section of the groove 9.
  • the thin elastic layer 5 is adhered, which covers the support surface 13 with the release of the passage opening 12 and recesses 16 over the entire surface.
  • the recesses 16 are formed in the bearing surface 13 in the mounting position of the rail 2 associated edge.
  • the elastic layer 5 consists of a finely porous, highly elastic polyurethane foam, the elasticity of which is such that it automatically relaxes automatically even after a prolonged complete compression suddenly discharge and again expands to the initial thickness of the elastic layer 5.
  • This initial thickness is a maximum of 8% of the average thickness of the angled guide plate 4 in the region of its support surface thirteenth
  • the angle guide plate 4 is placed on the support surface 8 that the formed on the bottom of the angled guide plate 4 projections 15 engage positively in the groove 9 and so the angle guide plate 4 against displacement in Secure the longitudinal direction of the threshold 3.
  • the support surface 13 sits on the elastic layer 5 on the end portion of the support surface 8 so that the passage opening 12 of the angle guide plate 4 is aligned with the dowel 10 of the threshold 3.
  • the elastic layer 5 In the course of tightening the tension clamp 6, the elastic layer 5 is fully compressed so far that its elasticity has no influence on the overall elasticity of the system 1. Is it due to the entering when passing over the rail 2 by an unillustrated rail vehicle movements in the system 1 to Lifting the angle guide plate 4 of the support surface 8 of the concrete sleeper 3, so the elastic layer 5 expands and fills the gap forming in this case between the support surface 8 and the support surface 13 of the angled guide plate 4 completely. In this way it is prevented that particles fall between the angled guide plate 4 and the concrete sleeper 3 and cause abrasive wear there.
