Definitions

  • the present invention relates to a method for protecting a rail vehicle axle, a railway vehicle axle thus produced, and a railway vehicle bogie comprising at least one such axle.
  • railway vehicles are equipped with wheels, which are most often mounted in pairs, on respective axles.
  • wheels In service, there is a risk of stones being thrown from the ballast to the axles, which can cause cracks. The size of the latter is able to progress, to cause a rupture of the entire axle.
  • a first solution is to project polyurethane, so as to form a peripheral coating around the axle. This implies, however, a high manufacturing cost. Moreover, once the coating is put in place, it is no longer possible to directly detect any superficial defects present at this axle.
  • WO-A-00/59764 teaches to place, around the axle, shells molded and then machined, which are based on polymer. This last solution proves to be expensive since, for each diameter and each axle length to be protected, it is necessary to count with a specific mold, as well as with a suitable machining.
  • the invention aims to remedy the various disadvantages of the prior art mentioned above.
  • the invention also relates to a railway vehicle axle, intended to connect at least two wheels of said vehicle, provided with at least one flexible protective strip made of a polymer material, the or each strip being wound around a region corresponding axle to be protected, in particular with regard to projections of the ballast, and for which there is further provided means for fixing the or each strip relative to the axle, characterized in that the or each strip is provided at its longitudinal ends with two beveled faces which are in mutual contact.
  • the invention finally relates to a railway vehicle bogie, comprising several axles, each of which connects at least two wheels, characterized in that each axle is as defined above.
  • the figure 1 illustrates an axle 2, of known type, which interconnects two wheels 4 belonging to a railway vehicle bogie, not shown.
  • This axle 2 comprises in known manner a cylindrical main rod 6, which is connected to the wheels 4 by peripheral shoulders 8.
  • the figure 1 illustrates also a strip 10, intended to cover the outer periphery of the axle 2.
  • This strip is made of a plastic material, such as polyurethane. It has a hardness of between 80 and 110 Shore A, preferably between 90 and 100 Shore A, in particular around 95 Shore A.
  • the constituent material of this band 10 may advantageously have other remarkable characteristics. Thus, it can in particular be moldable plate, and be machinable.
  • the thickness e of this band is advantageously between 8 and 10 mm. Moreover, its length corresponds to the width of the axle 2, while the width of this band corresponds to the perimeter of this axle.
  • This band 10 is cut advantageously from a plate, not shown, having larger dimensions. As shown in figure 2 grooves 12 are formed laterally in this band, once the latter has optionally been cut.
  • the longitudinal ends of the strip 10 are bevelled, so as to form two end faces 10 1 and 10 2 .
  • the longitudinal ends of the strip 10 are bevelled, so as to form two end faces 10 1 and 10 2 .
  • Such a holding member is for example a metal link, especially stainless steel, or a self-tightening collar.
  • a metal link especially stainless steel
  • a self-tightening collar it should be noted that it is also possible to bond each other, by gluing, the strip 10 and the rod 6 of the axle 2.
  • the figure 5 illustrates, seen from the front, the axle 2 covered by the belt 10. It may be noted that this band 10 is provided with lateral shoulders 11, extending in the vicinity of those 8 of the axle 2, so as to maintain substantially constant the thickness e of this band.
  • the fold initiation grooves 12 may be replaced by equivalent embodiments, such as grooves. These grooves or grooves may be present on the inside or outside of the strip.
  • each groove 12 ' is formed laterally in the strip 10', once the latter has been optionally cut.
  • the radius of curvature r of each groove is for example advantageously between 3 and 5 mm, while its depth is for example close to half the thickness of the strip 10 '.
  • FIG 6 illustrates an alternative embodiment of the invention.
  • the mechanical elements similar to those of the preceding figures are assigned the same reference numbers, increased by 100.
  • axle 102 connecting two wheels 104.
  • This axle differs from that 2 of the preceding figures, in that it is also provided with brake disks 105, mounted in conventional manner on the rod 106.
  • These strips 110A, 110B, 110C are similar to that 10, of larger size, of the preceding figures. Moreover, the assembly of these three bands, around Corresponding regions 102A to 102C are operated in the same manner as described above.
  • the three strips 110A, 110B and 110C can be replaced by strips similar to that of Figures 2A to 4A .
  • these strips are provided, on their outer face, fold initiation grooves, while having transverse dimensions smaller than those of the aforementioned strip 10 '.
  • the invention makes it possible to achieve the objectives mentioned above.
  • the or each protective band can be implemented simply and quickly, around the axle, without the need to use specific tools. Moreover, the disassembly of the band is effected easily, by removing the mechanical holding member.
  • the solution provided by the invention proves to be considerably less expensive than that described in WO-A-00/59764 , where it is especially necessary to use a specific mold.
  • the invention allows to use plastic bands of simple structure, the cost is relatively low. This is particularly remarkable in the case where these strips are obtained from plates of larger dimensions.
