Definitions

  • the present invention relates to a support device for the rails of a railroad track laid on ballast.
  • a problem which therefore arises is that of protecting the anti-vibration sole while at the same time preserving good support for the cross member in order to ensure sufficient stability of the cross member in the ballast, while taking account of the variable dimensions of the cross members, by example in the switchgear areas.
  • 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 track due to a lack of stability of a sleeper.
  • Another problem which arises is that of producing a support device which allows uniform loading of the elastic sole when the cars of the railway trains are passing on the rails.
  • the invention aims to solve these problems using an improved rail support device.
  • the support device comprises a cross resting on an anti-vibration sole and a liner of elastic material enveloping the base and the lateral faces of the elastic sole and at least the lower part of the lateral faces of the cross.
  • the dynamic stiffness of the elastic sole is chosen to be lower than that of the liner.
  • a distribution plate of relatively rigid material disposed below the elastic sole, inside the liner or under the base of the liner.
  • the elastic sole under the cross member is protected and therefore does not deteriorate, and its anti-vibration behavior is improved.
  • the base of the liner ensures uniform loading of the elastic sole when passing a car on the rails. This load distribution effect is further improved by a distribution plate.
  • This distribution plate can be made of wood, metal, plastic, rubber, polyamide or any other natural or synthetic material.
  • the damping time constant of the rail deformations is effectively reduced by selecting for the elastic sole 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 relatively rigid supports to that of 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 found amortized in a very short period of time so that resonances between the rails and the car are avoided, which are not only annoying for passenger comfort but also harmful for the rolling stock and the stability of the rails.
  • the spacing between two successive anti-vibration supports is a function of the type of rail and the dynamic stiffness of the anti-vibration pads used in these supports.
  • the reference sign 11 designates a railroad cross member and the reference sign 19 designates the ballast.
  • the rails carried by the cross member 11 are not shown.
  • the cross member 11 rests on an anti-vibration sole 13 and this rests here on a distribution plate 15 made of any relatively rigid material: wood, metal, plastic, rubber, polyamide or any other natural or synthetic material.
  • a liner 17 made of elastic material, for example an elastomer, envelops the base and the lateral faces of the distribution plate 15, the lateral faces of the anti-vibration sole 13 and at least part of the lateral faces of the cross member 11.
  • the dynamic stiffness of the antivibration sole is chosen to be less than that of the liner.
  • the liner protects the anti-vibration elastic sole placed under the crossmember. It is cut or fabricated 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 chosen according to the cross member and so as to ensure the best possible tightening around the cross member while allowing easy introduction of the cross member as well as easy extraction of the cross member for replacement or maintenance.
  • the attachment of the side walls to the crosspiece is by any means: gluing, nailing, stapling, strapping, for example.
  • the distribution plate arranged between the elastic anti-vibration sole and the ballast promotes uniform loading of the anti-vibration sole when passing a car on the rails and improves the anti-vibration behavior of the anti-vibration sole placed under the crossmember.
  • FIG 2 is a cross section in the embodiment of Figure 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 anti-vibration sole 13, inside the liner 17 which rests on the ballast 19 of the railroad track.
  • the distribution plate 15 can also be placed below the base of the liner.
  • Such an embodiment is illustrated in Figure 3, in which the ballast is not shown either.
  • the liner 17 here wraps the base and the lateral faces of the anti-vibration sole 13 and the lateral faces of the cross member 11 up 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 can be incorporated into the liner or the base of the liner can itself serve as a distribution plate.
  • the dynamic stiffness of the anti-vibration sole 13 is chosen such that successive supports along the rails alternately form relatively rigid supports and relatively flexible supports, the supports being alternated at regular distance.
  • the ratio of the dynamic stiffness of relatively rigid supports to that of 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 absorbed in a very short period of time, which avoids the production of resonances between the rails and the car, which are not only disturbing for the comfort of the travelers. but are also harmful to rolling stock and the stability of the rails.
  • the spacing between two successive anti-vibration supports is determined according to the type of rail and the dynamic stiffness of the anti-vibration pads used in these supports.
