Definitions

  • the invention relates to a system for fastening a rail for rail vehicles on a substrate.
  • a system according to the invention comprises a lower plate, a fastening means for securing the lower plate to the substrate, a top plate, an elastic intermediate layer arranged between the lower plate and the upper plate, via which the upper plate is elastically supported against the lower plate, and at least one braced against the upper plate Spring element, which exerts a resilient hold-down force on the rail of the rail to be fastened in fully assembled system.
  • top plate is arranged in a receptacle which is formed on the side facing away from the underside of the upper surface of the lower plate, wherein the elastic intermediate layer is also arranged in the receptacle.
  • the top plate on which the rail to be fastened stands when the system is completely assembled, by means of the elastic intermediate layer with coupled to the lower plate over which the actual fixation of the rail fastening point formed by the fastening system takes place on the respective substrate.
  • the top plate-carrying elastic intermediate layer is made of a highly elastic, firmly and permanently connected to the top plate and the bottom plate material, so that the top plate, the bottom plate and arranged between them Interlayer together form a highly elastic composite on which the rail to be fastened is mounted. Vibrations of the top plate, to which it is unavoidable when crossing the relevant attachment point, are therefore only attenuated passed into the ground. As a result, a significant reduction of the noise emissions can be achieved.
  • the usually consisting of a rubber material elastic intermediate layer is in each case both with the rule of steel or other sufficiently strong material existing upper and lower plates cohesively, for example by a Vulkanisiervorgang firmly connected.
  • the upper plate and the intermediate layer receiving receptacle of the lower plate is generally formed as a through hole with conically in the direction of the respective background associated bottom of the substrate tapered side surfaces. The seated between the side surface and the correspondingly shaped outer surfaces of the upper plate elastic layer then not only carries the weight of the top plate, but also the weight of the rail vehicle when driving over.
  • the object of the invention to provide a system for fastening a rail for rail vehicles, on the one hand, the benefits of a system of the above-mentioned type, but on the other hand, the life is significantly improved by the risk of overloading the elastic Interlayer is minimized.
  • An inventive system for fastening a rail for a rail vehicle accordingly comprises in addition to the features already mentioned at least one hold-down, which has a fastening portion, via which it can be fastened to the ground, and a hold-down portion, the in completely assembled, in the new state system protrudes with its free end portion over a side portion of the top plate and is arranged with the top plate associated surface of this end portion above its associated side portion of the top plate at a distance corresponding to the maximum permissible path of movement, which directed the top plate in a direction away from the ground Direction when loaded by a rail vehicle running over the rail performs.
  • the inventively provided holddown so limited in a fully assembled mounting system of the type according to the invention, the distance by which the top plate with the standing on her rail can stand out from the respective surface. Regardless of whether the lower plate and the top plate are firmly connected by the intermediate layer, it is ensured in this way that the top plate at any time can not lift so far that it comes to an overload of the elastic intermediate layer.
  • the hold-down is designed so that the upper plate can not leave the record provided in the lower plate at any time. Even if, as a result of aging or external influences, the elastic intermediate layer is fatigued to such an extent that it no longer occupies its original volume, this ensures that the rail is still held in the fastening point formed by the system according to the invention.
  • the hold-down device provided according to the invention simultaneously permits the mobility of the top plate required for the desired vibration and sound damping.
  • the introduction of a hold-down device according to the invention thus provides a fastening system for rails that not only makes optimum use of the proven basic design to minimize the noise emissions, but at the same time in a particularly simple and cost-effective manner to achieve optimal reliability even in the case It is ensured that the essential for the sound-absorbing function elastic intermediate layer is exposed to high loads.
  • the side section of the top plate associated with the hold-down element can be covered with an elastic material.
  • a suitably shock-absorbing elastic material may also be provided on the surface of the hold-down member associated with the top plate and possibly coinciding with the top plate.
  • the lower plate which receives the top plate and the intermediate layer, as formed in the generic state of the art as a through hole and the top plate supported by the intermediate layer, it may be counteracted by a possible wear of the intermediate layer improper lowering of the top plate, characterized in that on the underside of the top plate associated with the ground there is formed a stop projecting in the direction of the ground, which stop is arranged at a certain distance from the ground when the system is completely assembled and in the new state. If, as a result of wear, the original volume of the intermediate layer has been reduced so much that the top plate sinks into the receptacle of the lower plate, the stop restricts this lowering movement in such a way that unacceptable lowering of the rail standing on the top plate is prevented.
  • the distance of the stop on the underside of the top plate to the ground on which the fastening system is mounted is dimensioned such that a sufficient elastic compliance of the elastic intermediate layer is ensured in the unworn state.
  • An intended according to the invention on the underside of the top plate stop can thus be used on the one hand to limit the travel of the elastic layer to a favorable for their long-term reliable function level.
  • it can be ensured by means of the stop when the intermediate layer is destroyed that the rail is reliably guided until the repair of the respective rail support point.
  • the stop In order to minimize acoustic emissions in repeatedly occurring large deflections of the movement of the top plate and the associated contacts of the stop with the ground, the stop can be surrounded by elastic material.
  • the assembly of a system according to the invention is particularly simple if laterally a mounting portion with at least one passage opening for the fastening means for attachment to the substrate is formed on the lower plate. Optimum accessibility results when the mounting portion is formed on a side of the lower plate extending parallel to the longitudinal side of the rail to be fastened.
  • fastening means can also be used to attach the hold-down when the hold-down with his Attachment portion can be placed on the mounting portion and in the attachment portion at least one through hole is formed, which is arranged in the mounting position in alignment with the passage opening of the mounting portion of the lower plate.
  • a secure stationary hold of the hold-down to the respective mounting portion of the lower plate can be ensured in a simple manner that are formed on the underside facing the substrate underside of the mounting portion of the hold-down mold elements, which in the assembled system with correspondingly shaped on the top of the holddown associated top of the mounting portion formed form elements interact positively.
  • the openings of the mounting portion or the downholder as elongated holes, adjustment of the position of the bottom plate with respect to the rail to be fastened and the hold-down with respect to the bottom plate can be easily made possible.
  • the positionally correct arrangement of the hold-down on the respective mounting portion can additionally be assisted in that a positioning opening is formed in the mounting portion and a pin is formed on the hold-down, which engages positively with the assembled system in the opening of the mounting portion.
  • a correspondingly clear arrangement or shaping the positioning opening or the pin can be designed in a simple manner so that the hold-down can be mounted in each case only in one position on the lower plate.
  • the top plate or the bottom plate of a system according to the invention can be made in a conventional manner from a steel or other metal material. However, in terms of weight saving, it may also be appropriate to manufacture at least one of the plates of a plastic material, which is optionally fiber-reinforced.
  • the weight of the top plate can also be minimized by the fact that in the background of the underside of the top plate a recess is formed. In order to be able to interpret this recess with a view to maximizing the material and weight savings associated therewith, but also to ensure a sufficient load-bearing capacity of the top plate, it may be expedient to install in the recess below the contact surface on which the rail to be fastened fully assembled system is to form at least one reinforcing rib.
  • the bracing of the spring element required for holding down the rail to be fastened can be simplified by using a conventional tightening screw or a suitably designed bolt as the tightening means.
  • This allows, for example, in the prior art often proven clamps to use as spring elements.
  • at least one receptacle may be formed on the top plate, is supported on the peripheral walls in the assembled system, the head of the screw or a correspondingly shaped counter-holder of the clamping element used in each case.
