Description

La présente invention concerne les appareils de voie pour réseau ferroviaire, et a plus particulièrement pour objet un dispositif de fixation élastique de rails d'appareils de voie, en particulier d'un rail contre-aiguille d'aiguillage positionné dans un coussinet de glissement.The present invention relates to track apparatus for railway network, and more particularly relates to a elastic fastening of track apparatus rails, in particular a counter-needle rail switch positioned in a slip pad.

Des dispositifs de ce type sont notamment connus, par exemple, par DE-A-21 53 534, DE-A-32 30 612, DE-A-255 758, EP-A-0 275 604 ainsi que par DE-A-24 09 13 8.Devices of this type are known, for example, by DE-A-21 53 534, DE-A-32 30 612, DE-A-255 758, EP-A-0 275 604 as well as by DE-A-24 09 13 8.

Les aiguillages des réseaux ferroviaires sont habituellement constitués, pour chaque file de rails, par un rail contre-aiguille fixe avec lequel coopère un rail-aiguille mobile se déplaçant transversalement à l'axe de la voie, et pouvant être, à volonté, appliqué ou séparé du rail contre-aiguille adjacent.Switching of railway networks is usually constituted, for each line of rails, by a fixed counter-needle rail with which cooperates a movable needle rail moving transversely to the axis of the track, and can be, at will, applied or separated from the counter-needle rail adjacent.

Un aiguillage est dit à "aiguille haute" dans le cas où le rail-aiguille présente la même hauteur que le rail contre-aiguille, et à "aiguille basse" dans le cas où le rail-aiguille est de hauteur moindre que le rail contre-aiguille.A switch is said to "high needle" in the case where the needle rail has the same height as the counter-needle and needle where the needle rail is of lesser height than the rail against needle.

Dans le cas d'un aiguillage à "aiguille basse", le rail-aiguille repose par sa partie mobile sur des coussinets de glissement. Afin de maintenir le rail contre-aiguille élastiquement du côté intérieur de la voie, il est généralement mis en oeuvre un coussinet de glissement particulier, qui comporte un évidement permettant l'insertion d'une attache élastique sensiblement en forme de U, la tête de cette attache reposant sur le patin interne du rail contre-aiguille. L'effort d'appui sur le patin, qui est de l'ordre de 1200daN, est obtenu par la mise en tension de cette attache par disposition des deux extrémités de ses branches dans deux logements surélevés prévus à cet effet et situés à l'extrémité du coussinet.In the case of a "low needle" switch, the needle rail rests by its mobile part on sliding bearings. In order to keep the rail counter-needle elastically on the inside of the track, it is usually implemented a particular slip pad, which has a recess for inserting an elastic tie substantially U-shaped, the head of this fastener resting on the pad internal counter-needle rail. The support effort on the skate, which is of the order 1200daN, is obtained by the tensioning of this fastener by arrangement of the two ends of its branches in two dwellings elevations provided for this purpose and located at the end of the pad.

Les dispositifs de fixation élastique de rails de ce type existant actuellement présentent, cependant, encore de nombreux inconvénients.The devices for elastic fastening of rails of this type present, however, still have many disadvantages.

Ceux-ci sont dus, en particulier au fait que l'attache élastique est une pièce sensible du dispositif et doit ainsi être positionnée de manière précise et sans subir aucun dommage lors de sa mise en place, afin d'éviter une dégradation prématurée, qui entraínerait une augmentation des risques de rupture mettant gravement en jeu la sécurité.These are due, in particular to the fact that the elastic tie is a sensitive part of the device and must thus be positioned precise and without suffering any damage during its installation, in order to avoid premature degradation, which would lead to increased risks breach seriously jeopardizing security.

Avec les dispositifs connus à ce jour, le montage s'effectue, en principe, en cinq étapes, à savoir l'insertion de l'attache dans l'évidement, la mise en place d'une branche en position intermédiaire, son déplacement jusqu'en position finale, suivi par la mise en place de l'autre branche en position intermédiaire et son déplacement jusqu'en position finale.With the devices known to date, the assembly is carried out, in principle, in five steps, namely the insertion of the fastener into the recess, the setting up a branch in the middle position, moving it until the final position, followed by the establishment of the other branch intermediate position and its movement to the final position.

Dans la pratique, cette succession d'opérations s'effectue avec quelques difficultés. En effet, dans sa position intermédiaire la branche de l'attache est déjà sous tension, sans pour autant être dans sa position finale stable. Cette situation instable peut provoquer un retour violent de ladite branche dans sa position initiale, ce qui est néfaste à sa tenue dans le temps et à son bon fonctionnement.In practice, this succession of operations is carried out with some difficulties. Indeed, in its intermediate position the branch of the fastener is already under tension, without being in its final position stable. This unstable situation may cause a violent return of the said branch in its initial position, which is harmful to its behavior over time and to its good functioning.

De plus, dans les dispositifs connus le positionnement longitudinal de l'attache dans l'évidement reste assez aléatoire, et ne peut être garanti de manière répétée et rigoureuse, du fait qu'elle est montée sur chaise et qu'un tel montage doit être effectué avec un jeu. Il en résulte que l'effort d'application devient variable et n'est donc pas connu et ne peut de ce fait être garanti.Moreover, in the known devices the positioning length of the fastener in the recess remains rather random, and can not be repeatedly and rigorously guaranteed, because it is based on chair and that such an assembly must be performed with a game. It follows that the application effort becomes variable and is therefore not known and can not this is guaranteed.

Lorsque l'ensemble de l'appareil de voie est en fonctionnement, il se produit des vibrations qui tendent à faire avancer l'attache ou épingle, de sorte que le jeu augmente et que l'effort d'application évolue et peut tendre jusqu'à une diminution de l'ordre de 50 %. Il s'ensuit que l'épingle peut se démonter entièrement sous l'effet des trépidations et que le maintien du rail n'est plus assuré, ce qui peut avoir de très graves conséquences du point de vue de la sécurité. Cet inconvénient existe également lorsqu'on est en présence d'un coussinet pourvu d'une butée, qui risque une usure prématurée, du fait des déplacements dûs aux vibrations.When the whole of the switchgear is in operation, there are vibrations that tend to advance the fastener or pin, so that the game goes up and the application effort evolves and can to a decrease of about 50%. It follows that the hairpin can be dismounted entirely under the effect of the trepidations and that the maintenance rail is no longer insured, which can have very serious consequences for the security point of view. This disadvantage also exists when one is in the presence of a bearing provided with a stop, which risks wear premature, due to movements due to vibrations.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de fixation élastique de rails d'appareils de voie, en particulier d'un rail contre-aiguille d'aiguillage positionné dans un coussinet de glissement permettant un positionnement précis de ce dernier et évitant tout risque d'usure rapide.The present invention aims to overcome these disadvantages by proposing a device for elastic fastening of rails of switchgear, in particular of a counter-needle routing rod positioned in a bearing slip allowing a precise positioning of the latter and avoiding any risk of rapid wear.

A cet effet, le dispositif de fixation élastique de rail d'appareils de voie, en particulier d'un rail contre-aiguille fixe d'aiguillages coopérant avec un rail-aiguille mobile pouvant se déplacer transversalement à la voie, ces rails reposant sur un coussinet de glissement, le rail contre-aiguille étant maintenu sur le coussinet, d'une part, du côté extérieur de la voie par un moyen de fixation et, d'autre part, du côté intérieur de la voie par une attache élastique sensiblement en forme de U, disposée dans un évidement du coussinet et dont les extrémités des branches pénètrent, en position de mise en tension de l'attache élastique, par l'intermédiaire d'une butée assurant l'effort de placage du rail contre-aiguille sur le coussinet, dans des logements surélevés prévus à cet effet dans ledit coussinet, est caractérisé en ce que l'attache élastique comporte, près de l'extrémité de chaque branche du U la formant, un élément en saillie, en forme de bosse ou d'ergot d'une seule pièce avec ladite extrémité.For this purpose, the device elastic fastening device of track, in particular of a fixed counter-needle rail of cooperating switches with a movable needle rail that can move transversely to the track, these rails resting on a sliding pad, the counter-needle rail being maintained on the pad, on the one hand, on the outer side of the track by a means of attachment and, on the other hand, on the inside of the track by a elastically substantially U-shaped fastener disposed in a recess of the pad and whose ends of the branches penetrate, in the position of tensioning of the elastic fastener, via an abutment ensuring the plating force of the counter-needle rail on the pad, in raised housing provided for this purpose in said bearing, is characterized in that what the elastic fastener has, near the end of each branch of the U forming it, a projecting element, in the form of a bump or ergot of a only one piece with said end.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation et en coupe d'un dispositif de fixation conforme à l'invention ;
  • la figure 2 est une vue partielle en plan du coussinet de glissement, et
  • la figure 3 est une vue en plan de l'attache élastique seule.
    • The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • Figure 1 is an elevational view in section of a fastener according to the invention;
  • FIG. 2 is a partial plan view of the sliding pad, and
  • Figure 3 is a plan view of the elastic fastener alone.

    • Les figures 1 et 2 des dessins annexés représentent un dispositif de fixation élastique de rail d'appareils de voie, en particulier d'un rail contre-aiguille fixe 1 d'aiguillages coopérant avec un rail-aiguille mobile (non représenté) pouvant se déplacer transversalement à la voie, ces rails reposant sur un coussinet de glissement 2, le rail contre-aiguille 1 étant maintenu sur le coussinet 2, d'une part, du côté extérieur de la voie par un moyen de fixation (non représenté) et, d'autre part, du côté intérieur de la voie par une attache élastique 3 sensiblement en forme de U, disposée dans un évidement 4 du coussinet 2 et dont les extrémités des branches 5 pénètrent, en position de mise en tension de l'attache élastique 3, par l'intermédiaire d'une butée 6 assurant l'effort de placage du rail contre-aiguille 1 sur le coussinet 2, dans des logements surélevés 7 prévus à cet effet dans ledit coussinet 2.Figures 1 and 2 of the accompanying drawings show a device for the elastic fixing of rail of track apparatus, in particular of a rail fixed counter-needle 1 of switches cooperating with a movable needle rail (not shown) can move transversely to the track, these rails resting on a sliding bearing 2, the counter-needle rail 1 being maintained on the pad 2, on the one hand, on the outer side of the track by a fixing means (not shown) and, on the other hand, on the inner side of the track by a resilient fastener 3 substantially U-shaped, disposed in a recess 4 of the pad 2 and whose ends of the branches 5 penetrate, in the tensioning position of the elastic fastener 3, by via a stop 6 ensuring the plating force of the counter-needle rail 1 on the pad 2, in raised housing 7 provided for this effect in said pad 2.

    Conformément à l'invention et comme le montrent les figures 1 à 3 des dessins annexés, l'attache élastique 3 comporte, près de l'extrémité de chaque branche 5 du U la formant, un élément en saillie 8, en forme de bosse ou d'ergot d'une seule pièce avec ladite extrémité. De préférence, les éléments en saillie 8 de l'attache élastique 3, en forme de bosses ou d'ergots, sont réalisés par forgeage.According to the invention and as shown in FIGS. 3 to the attached drawings, the elastic clip 3 comprises, near the end of each branch 5 of the U forming it, a projecting element 8, in the form of bump or lug in one piece with said end. Preferably, protruding elements 8 of the elastic fastener 3, in the form of bumps or lugs, are made by forging.

    Ces éléments en saillie 8, prévus près de l'extrémité de chaque branche 5 de l'attache élastique 3, sont conçus pour assurer l'insertion de l'attache élastique 3 jusqu'à sa position longitudinale normale dans l'évidement 4 du coussinet 2, avec obtention d'un positionnement longitudinal parfait de ladite attache élastique 3.These protruding elements 8, provided near the end of each branch 5 of the elastic clip 3, are designed to ensure the insertion of the elastic fastener 3 to its normal longitudinal position in the recess 4 of the pad 2, with obtaining a positioning longitudinal section of said elastic fastener 3.

    Ainsi, il est possible de réaliser un bon positionnement longitudinal de l'attache élastique 3, tout en empêchant un enfoncement trop profond de ladite attache élastique 3 dans l'évidement 4 du coussinet 2 et ainsi tout risque de coincement de celle-ci en position de service, du fait que les éléments en saillie 8 équipant l'extrémité des branches 5 de l'attache élastique 3 viennent se plaquer contre le rebord supérieur 4' de l'évidemment 4 du coussinet 2, dans une position d'enfoncement maximal.Thus, it is possible to achieve a good positioning longitudinal of the elastic fastener 3, while preventing a depression too deep of said elastic fastener 3 in the recess 4 of the pad 2 and thus any risk of jamming of the latter in the service position, because the projecting elements 8 equipping the end of the branches 5 of the fastener elastic 3 are pressed against the upper edge 4 'of the obviously 4 of the pad 2, in a maximum depression position.

    Il s'ensuit que, lorsque l'attache élastique 3 est insérée totalement longitudinalement dans l'évidemment 4, celle-ci se positionne dans ledit évidemment, éventuellement sans que ses éléments en saillie 8 entrent en contact avec le rebord supérieur 4'. Les vibrations se produisant lors du fonctionnement normal de l'aiguillage, qui ont pour effet d'induire une tendance de l'attache élastique 3 à se déplacer dans l'évidemment 4, ne peuvent provoquer un tel déplacement que dans une mesure très limitée, à savoir sur une distance correspondant à la différence entre la longueur de l'ouverture de l'évidemment 4 et la distance entre l'extrémité des branches 5 de l'attache élastique 3 et le bord distal des éléments en saillie 8, cette distance étant légèrement inférieure à la longueur de l'ouverture de l'évidement 4.It follows that when the elastic fastener 3 is inserted totally longitudinally in the recess 4, this one is positioned in said obviously, possibly without its protruding elements 8 come into contact with the upper rim 4 '. Vibrations occurring during the normal operation of the switch, which have the effect of inducing a tendency of the elastic fastener 3 to move in the recess 4, do not can cause such displacement only to a very limited extent, know about a distance corresponding to the difference between the length of the opening of the recess 4 and the distance between the ends of the branches 5 of the elastic fastener 3 and the distal edge of the projecting elements 8, this distance being slightly less than the length of the opening of the recess 4.

    Cette distance est parfaitement maítrisable par construction, de sorte que l'attache élastique 3 ne peut se déplacer que dans une limite très précise, définie et connue et que sa position est parfaitement garantie. Il en résulte que les inconvénients inhérents aux attaches connues à ce jour sont évités.This distance is perfectly manageable by construction, so that the elastic fastener 3 can move only in a very limited accurate, defined and known and that its position is perfectly guaranteed. It results that the disadvantages inherent to the fasteners known to date are avoided.

    Grâce à l'invention il est possible de réaliser un dispositif de fixation élastique de rails d'appareils de voie, en particulier de rails contre-aiguilles d'aiguillages permettant un positionnement précis de ces derniers et évitant tout risque de désolidarisation de celle-ci d'avec le coussinet.Thanks to the invention it is possible to produce a device for elastic fastening of track apparatus rails, in particular counter-needle rails turnouts for accurate positioning of these and avoiding any risk of separation of it from the pad.

    Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly from the point of view of the constitution of the various elements or by substituting technical equivalents, without departing of the field of protection of the invention.
