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 railway track apparatus, and more particularly to a device for elastic fastening of track apparatus rails, in particular a counter-needle routing rail positioned in a sliding bushing.

Des dispositifs de ce type sont notamment connus, par exemple, par DE-A-21 53 534, DE-A-32 30 612, EP-A-0 275 604 ainsi que par DE-A-24 09 138.Devices of this type are known, for example, from DE-A-21 53 534, DE-A-32 30 612, EP-A-0 275 604 and DE-A-24 09 138.

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.The switches of the railway networks are 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 adjacent counter-needle rail.

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 rail, and "needle low" in the case where the needle rail is of less 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 switch with "low needle", the needle rail rests by its mobile part on sliding bearings. In order to keep the counter-needle rail elastically on the inside of the track, it is generally implemented a particular sliding bearing, which comprises a recess allowing the insertion of a substantially U-shaped elastic fastener, the head of this fastener resting on the inner shoe of the counter-needle rail. The support force on the pad, which is of the order of 1200daN, is obtained by the tensioning of this fastener by provision of the two ends of its branches in two raised housing 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 existing elastic fasteners for rails of this type, 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 entraînerait une augmentation des risques de rupture mettant gravement en jeu la sécurité.These are due, in particular to the fact that the elastic fastener is a sensitive part of the device and must thus be positioned accurately and without suffering any damage during its introduction, to avoid premature degradation, which would lead to an increased risk of breakage that seriously jeopardizes safety.

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 in the recess, the setting up a branch in intermediate position, its displacement to the final position, followed by the establishment of the other branch in the 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 stable position. This unstable situation can cause a violent return of said branch in its initial position, which is detrimental to its behavior over time and its proper 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 longitudinal positioning of the fastener in the recess remains rather random, and can not be guaranteed repeatedly and rigorously, because it is mounted on a chair and such a fitting must be performed with a game. As a result, the application effort becomes variable and is therefore not known and can not be 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, vibrations occur which tend to advance the clip or pin, so that the game increases and the application force evolves and can stretch until to a decrease of about 50%. It follows that the pin can disassemble entirely under the effect of trepidations and that the maintenance of the rail is no longer ensured, which can have very serious consequences from the point of view of safety. This disadvantage also exists when there is in the presence of a pad provided with a stop, which risks premature wear, due to displacements 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 object of the present invention is to overcome these drawbacks by proposing a device for elastic fastening of rails of track apparatus, in particular a counter-needle routing rod positioned in a sliding bushing allowing precise positioning of the latter. and avoiding any risk of rapid wear.

A cet effet, le dispositif pour la fixation élastique d'un rail contre-aiguille fixe d'aiguillages coopérant avec un rail-aiguille mobile pouvant se déplacer transversalement à la voie, le dispositif comprenant un coussinet formant appui pour le rail contre-aiguille et coussinet de glissement pour le rail-aiguille, le rail contre-aiguille étant, en position d'utilisation, maintenu, 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, ladite attache élastique étant disposée dans un évidement du coussinet, les extrémités respectives des branches de l'attache pénétrant, en position de mise en tension de ladite attache élastique, par l'intermédiaire d'une butée destinée à assurer 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, lesdits éléments en saillie venant se plaquer contre un rebord supérieur de l'évidement du coussinet, dans une position d'enfoncement maximal de l'attache dans ledit évidement.For this purpose, the device for the resilient attachment of a fixed counter-needle rail of points cooperating with a movable needle rail movable transversely to the track, the device comprising a bearing pad for the counter-needle rail and sliding pad for the rail needle, the counter-needle rail being, in the position of use, maintained, on the one hand, on the outer side of the track by a fastening means and, on the other hand, on the inside of the track by a fastener substantially U-shaped elastic, said elastic fastener being disposed in a recess of the bearing, the respective ends of the branches of the penetrating fastener, in tensioning position of said elastic fastener, via a stop intended for ensuring the force of plating the counter-needle rail on the bearing, in raised housing provided for this purpose in said bearing, is characterized in that the elastic fastener comprises, close to the end of each leg of the U forming it, a protruding element, in the form of a bump or lug in one piece with said end, said projecting elements being pressed against an upper edge of the recess of the bearing in a position of maximum depression of the fastener in said recess.

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 pour la fixation élastique d'un rail contre-aiguille fixe 1 d'aiguillages coopérant avec un rail-aiguille mobile pouvant se déplacer transversalement à la voie, le dispositif comprenant un coussinet 2 formant appui pour le rail contre-aiguille 1 et coussinet de glissement 2 pour le rail-aiguille, le rail contre-aiguille 1 étant, en position d'utilisation, maintenu, 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 3 sensiblement en forme de U, ladite attache élastique 3 étant disposée dans un évidement 4 du coussinet 2, les extrémités respectives des branches 5 de l'attache pénétrant, en position de mise en tension de ladite attache élastique 3, par l'intermédiaire d'une butée 6 destinée à assurer 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 fixation of a fixed counter-needle rail 1 of points cooperating with a movable needle-rail able to move transversely to the track, the device comprising a bearing pad 2 forming a support for the counter-needle rail 1 and a sliding pad 2 for the needle rail, the counter-needle rail 1 being, in the position of use, maintained, on the one hand, on the outer side of the track by a fixing means and, on the other hand, on the inner side of the track by a resilient fastener 3 substantially U-shaped, said elastic fastener 3 being disposed in a recess 4 of the bearing 2, the respective ends of the branches 5 of the penetrating fastener, in the tensioning position of said elastic fastener 3 , via a stop 6 intended to ensure the plating force of the counter-needle rail 1 on the pad 2, in raised housing 7 provided for this purpose 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, lesdits éléments en saillie venant se plaquer contre un rebord supérieur 4' de l'évidement 4 du coussinet 2, dans une position d'enfoncement maximal de l'attache dans ledit évidement.According to the invention and as shown in Figures 1 to 3 of the accompanying drawings, the resilient clip 3 comprises, near the end of each leg 5 of the U forming it, a protruding element 8, shaped like a hump or one-piece lug with said end, said projecting elements being pressed against an upper flange 4 'of the recess 4 of the bearing 2, in a position of maximum depression of the fastener in said recess.

De préférence, les éléments en saillie 8 de l'attache élastique 3, en forme de bosses ou d'ergots, sont réalisés par forgeage.Preferably, the projecting 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 projecting elements 8, provided near the end of each branch 5 of the elastic fastener 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 perfect longitudinal positioning 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 longitudinal positioning of the elastic fastener 3, while preventing too deep a depression of said elastic fastener 3 in the recess 4 of the pad 2 and thus any risk of jamming thereof in position of service, because the projecting elements 8 equipping the end of the branches 5 of the elastic clip 3 are pressed against the upper flange 4 'of the recess 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 fully longitudinally in the recess 4, it is positioned in said recess, possibly without its projecting elements 8 come into contact with the upper rim 4 '. The vibrations occurring during normal operation of the switch, which have the effect of inducing a tendency of the elastic fastener 3 to move in the recess 4, can cause such a displacement only to a very limited extent, namely a distance corresponding to the difference between the length of the opening of the recess 4 and the distance between the end 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 maîtrisable 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 controllable by construction, so that the elastic fastener 3 can move only in a very precise, defined and known limit and that its position is perfectly guaranteed. As a result, the disadvantages inherent to 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 for precise positioning of the latter and avoiding any risk of disconnection thereof. from with 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 tel que défini par les revendications annexées.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention as defined by the appended claims.
