Definitions

  • the present invention relates to a support device for the rails of a railway laid on ballast.
  • a problem that arises is that of the protection of the antivibration sole while maintaining a good maintenance of the cross member to ensure sufficient stability of the crossbar in the ballast, while taking into account the variable dimensions of the cross, by example in the areas of switches.
  • This stability of the sleepers is essential to ensure good reliability of the railway supported by the sleepers and thus prevent any deformation of the railway as a result of a lack of stability of a cross.
  • Another problem that arises is to provide a support device that allows a uniform loading of the elastic sole during the passage of cars trains trains on the rails.
  • EP-A-0569867 is already known a rail support device comprising a cross member resting on an elastic antivibratory sole with a liner surrounding the base and the lateral faces of the resilient antivibration sole and the lower part of the side faces of the cross member.
  • the invention aims to eliminate the disadvantages of the interior art and thus improve the stability of railroad tracks placed on ballast.
  • the rail support device comprises sleepers each resting on an antivibration sole with a slipper of elastic material wrapping the base and the lateral faces of the elastic sole and at least the lower part of the lateral faces of the crossbar, and a distribution plate.
  • the dynamic stiffness of the resilient sole is preferably chosen smaller than the liner and the distribution plate is made of a relatively rigid material, for example wood, metal, plastic, rubber, polyamide or any other natural or synthetic material.
  • the elastic sole under the crossbar is protected and therefore does not deteriorate, and its antivibration behavior is improved.
  • this device ensures uniform loading of the elastic base when a car passes on the rails.
  • the time constant of damping of the deformations of the rail is effectively reduced by selecting for the elastic base of each rail support, a dynamic stiffness such that the successive supports along each rail alternately form relatively rigid supports and relatively flexible supports.
  • the ratio of the dynamic stiffness of the relatively rigid supports to that of the relatively flexible supports is preferably equal to a factor of at least 5. Thanks to this arrangement, the vibrations of the rail during the passage of a car on the rails are in a very short time so that the resonances between the rails and the car are avoided, which are not only annoying for the comfort of the passengers but also harmful for the rolling stock and the stability of the rails.
  • the spacing between two successive antivibration mounts is a function of the type of rail and the dynamic stiffness of the antivibration mounts used in these mounts.
  • the reference sign 11 designates a railway crossing and the reference sign 19 designates the ballast.
  • the rails carried by the cross member 11 are not shown.
  • the crosspiece 11 rests on an antivibration base 13 and it rests here on a distribution plate 15 made of a relatively rigid material: wood, metal, plastic, rubber, polyamide or any other natural or synthetic material.
  • a liner 17 of elastic material for example an elastomer, surrounds the base and the lateral faces of the distribution plate 15, the lateral faces of the antivibration soleplate 13 and at least a portion of the lateral faces of the crosspiece 11.
  • the dynamic stiffness the antivibration sole is chosen to be lower than that of the liner.
  • the boot protects the antivibration elastic sole placed under the crossbar. It is cut or made from a sheet and has a bottom and side walls that attach to the bottom and are folded vertically. It can be made with any profile selected according to the cross and to ensure the best possible clamp around the cross while allowing easy introduction of the cross and easy removal of the cross for replacement or maintenance.
  • the attachment of the side walls to the cross member is by any means: gluing, nailing, stapling, strapping for example.
  • the distribution plate disposed between the antivibration resilient sole and the ballast promotes the uniform loading of the antivibration sole when a car passes over the rails and improves the antivibration behavior of the anti-vibration sole placed under the crossbar.
  • FIG. 2 is a cross-section in the embodiment of FIG. 1.
  • the ballast is not shown here to better show the arrangement according to the invention in a first embodiment.
  • the distribution plate 15 is housed under the antivibration sole 13, inside the shoe 17 which rests on the ballast 19 of the railway.
  • the distribution plate 15 can also be placed below the base of the liner.
  • Such an embodiment is illustrated in Figure 3, on which the ballast is not shown either.
  • the liner 17 envelops here the base and the lateral faces of the antivibration sole 13 and the lateral faces of the crosspiece 11 to a predetermined height.
  • the distribution plate 15 then rests on the ballast and provides the same effects as in the first embodiment.
  • the distribution plate may be incorporated in the liner or the base of the liner may itself serve as a distribution plate.
  • the dynamic stiffness of the antivibration sole 13 is chosen such that the successive supports along the rails alternately form relatively rigid supports and relatively soft supports, the supports being alternated at regular distance.
  • the ratio of the dynamic stiffness of the relatively rigid supports to that of the relatively flexible supports is preferably equal to a factor of at least 5.
  • the vibrations of the rail during the passage of a car on the rails are thus amortized in a very short period of time, which avoids the production of resonances between the rails and the car, which are not only annoying for the comfort of the travelers but are also harmful to the rolling stock and the stability of the rails.
  • the spacing between two successive antivibration mounts is determined according to the type of rail and the dynamic stiffness of the antivibration mounts used in these mounts.
