Definitions

  • the invention relates to a structure-borne sound absorbing rail bearing for rail vehicles, in which the rails rest on sleepers, metal plates or the like support the frame connected to the foundation, and in which a further elastic intermediate layer is arranged below the sleepers or the like, which rests only on the sleepers or the like or only on the foundation, so that o. between the further elastic intermediate layer and the sleepers . Like. Or there is a distance between the further elastic intermediate layer and the foundation.
  • Structure-borne sound-absorbing rail bearings of the aforementioned type are designed so that their maximum deflection is achieved at full load.
  • the distance between the further elastic intermediate layer and the sleepers or the like or between the further elastic intermediate layer and the foundation decreases more and more and finally - when the full load is reached - assumes the value zero.
  • the further elastic intermediate layer function; it serves as a kind of emergency stop, which prevents damage to the rail bearing if the full load is exceeded.
  • the structure-borne noise insulation is not optimal during this time.
  • the average load occurring during the above-mentioned 95% of daily traffic which is referred to as normal load, is approximately 70 to 80% of the full load.
  • normal load the average load occurring during the above-mentioned 95% of daily traffic
  • road traffic is also lower and the noise level due to road traffic is therefore considerably lower than during rush hour.
  • the lower the noise level from road traffic the stronger the structure-borne noise emitted by the rail vehicles.
  • the invention is therefore based on the object of designing the rail bearing of the type mentioned in such a way that optimum structure-borne sound insulation is achieved with normal loading of the rail bearing.
  • the inclined elastic intermediate layers are dimensioned such that their maximum deflection is achieved even with normal loading of the rail bearing - which is exercised by a normally loaded rail vehicle - and that the distance between the further elastic intermediate layer and the sleepers or the distance between the further elastic intermediate layer and the foundation is dimensioned such that it assumes the value zero when the normal load of the rail bearing is reached, so that the further elastic intermediate layer or the like already supports the sleepers. contributes when a rail vehicle with a slightly higher than normal load passes over the rail bearing.
  • the further elastic intermediate layer is provided with recesses.
  • the further elastic intermediate layer can also be provided with ribs, beads or the like, the beads being conical or pyramid-shaped in a further embodiment of the invention.
  • the rail bearing shown in Fig. 1 consists of a rail 1 carrying, designed as a rib plate threshold 2, which is supported by inclined elastic intermediate layers 3 against the frame 4 connected to the foundation 4.
  • Another elastic intermediate layer 6 is arranged on the foundation 4 such that a distance A2 remains between the threshold 2 and the surface of the elastic intermediate layer 6.
  • the further elastic intermediate layer 6 is provided with recesses 7 on its upper side.
  • a further elastic intermediate layer 6 is attached to the underside of the sleeper 2.
  • beads 8 are provided, which are conical or pyramid-shaped.
  • the beads 8 of the elastic intermediate layer 6 are at a distance A4 from the foundation 4.

Claims (4)

1. Support de rail amortissant le bruit, pour véhicule ferroviaire, dans lequel les rails courent sur des traverses, plaques métalliques ou analogues, qui s'appuient par l'intermédiaire de couches intermédiaires élastiques disposées en oblique à leur périphérie, comme des plaques en caoutchouc, des supports caoutchouc-métal ou analogues, sur des cadres support liés à la plate-forme, et dans lequel une autre couche intermédiaire élastique, qui n'est adjacente qu'aux traverses ou analogues, ou à la plate-forme, est prévue en-dessous des traverses ou analogues, de telle sorte qu'il existe un intervalle entre l'autre couche intermédiaire élastique et les traverses ou analogues, respectivement entre l'autre couche intermédiaire élastique et la plate-forme, caractérisé en ce que les couches intermédiaires élastiques (3) disposées en oblique sont dimensionnées de telle sorte que leur déformation élastique maximale est déjà atteinte pour une charge normale du support de rail - qui est déjà appliquée par un véhicule de chemin de fer de charge normale - et en ce que l'intervalle (A2) entre l'autre couche intermédiaire élastique (6) et les traverses (2), respectivement l'intervalle (A4) entre l'autre couche intermédiaire élastique (6) et la plate-forme (4) est dimensionné de telle sorte qu'il s'annulle lorsqu'est atteinte la charge normale du support de rail, de telle sorte que l'autre couche intermédiaire élastique (6) intervient déjà dans le support des traverses ou analogues, alors que passe sur le support de rail un véhicule de chemin de fer avec une charge légèrement plus grande que la charge normale.
2. Support de rail amortissant le bruit selon la revendication 1, caractérisé en ce que l'autre couche intermédiaire élastique (6) est pourvue d'évidements (7).
3. Support de rail amortissant le bruit selon la revendication 1 ou 2, caractérisé en ce que l'autre couche intermédiaire élastique (6) est pourvue de nervures, saillies (8) ou analogues.
4. Support de rail amortissant le bruit selon la revendication 3, caractérisé en ce que les saillies (8) sont coniques ou pyramidales.
