Definitions

the present invention relates to a method of protection of a railway vehicle axle, an axle of a railway vehicle thus produced, as well as a bogie of railway vehicle comprising at least one such axle.
railway vehicles are equipped with wheels, which are most often mounted by pair, on respective axles.
wheels In service, there is a risk of throwing stones, from the ballast to the axles, which can cause cracks.
the size of the latter is able to progress, to provoke a break in the entire axle.
WO-A-00/59764 teaches to dispose, around the axle, shells molded and then machined, which are polymer base. This last solution is revealed expensive since, for each diameter and each length of axle to protect, it is necessary to count with a mold specific, as well as with suitable machining.
the invention aims to remedy the various disadvantages of the prior art mentioned above.
the subject of the invention is also an axle of railway vehicle, intended to connect at least two wheels said vehicle, characterized in that it is provided with least one flexible protection strip, made in one polymeric material, the or each strip being wrapped around of a corresponding region of the axle to be protected, in particular with regard to ballast projections, and in that means are also provided for fixing the or each band relative to the axle.
the invention finally relates to a vehicle bogie railway, comprising several axles, each of which connects at least two wheels, characterized in that each axle is as defined above.
FIG. 1 illustrates an axle 2, of known type in itself, which connects two wheels 4 belonging to one 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 shoulders devices 8.
FIG. 1 also illustrates a band 10, intended to cover the outer periphery of the axle 2.
This strip is made of a plastic material, such only polyurethane. It has a hardness included between 80 and 110 Shore A, preferably between 90 and 100 Shore A, in particular around 95 Shore A.
the constituent material of this strip 10 can advantageously have other characteristics remarkable. Thus, it can in particular be moldable in 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 advantageously cut out from a plate, not shown, presenting more large dimensions. As shown in Figure 2, grooves 12 are formed laterally in this band, once it has been cut.
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 link metal, especially stainless steel, or a self-tightening collar.
a link metal especially stainless steel
a self-tightening collar it should be noted that it is also possible to fix each other gluing, the strip 10 and the rod 6 of the axle 2.
FIG. 5 illustrates, seen from the front, the axle 2 covered by the strip 10. It may be noted that this strip 10 is provided with lateral shoulders 11, extending in the vicinity of those 8 of the axle 2, in such a way that to maintain substantially constant the thickness e of this band.
the primer grooves 12 of folding can be replaced by achievements equivalent, such as throats. These grooves or these throats may be present on the inside or outside the band.
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 '.
the strip 10 ' is wound up so that the grooves 12' are present on the outer face of this band.
the mechanical maintenance of this band with respect to the axle is finally achieved in a similar way to what is described with reference to Figures 4 and 5.
FIG. 6 illustrates a variant embodiment of the invention.
the mechanical elements similar to those of the preceding figures are affected the same reference numbers, increased by 100.
axle 102 connecting two wheels 104.
This axle differs from that 2 of the preceding figures, in it is also provided with brake disks 105, mounted in a conventional manner on the rod 106.
the three bands 110A, 110B and 110C can be replaced by bands similar to that of FIGS. 2A to 4A.
these bands are provided, on their face outdoor, folding bait gorges, while with cross-sectional dimensions smaller than those of the aforementioned band 10 '.
the invention makes it possible to achieve the objectives previously mentioned.
the or each protective band can be setting up, simply and quickly, around the axle, without the need for tools specific. Moreover, the disassembly of the band takes place in an easy way, by removing the mechanical holding member.
the solution provided by the invention significantly less expensive than that described in WO-A-00/59764, where it is in particular necessary to use a specific mold.
the invention makes it possible to appeal to structural plastic strips simple, whose cost price is relatively low. This is particularly noteworthy in the case where these bands are obtained from larger plates dimensions.
