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'aiguillages. Des dispositifs de ce type sont notamment connus par exemple DE-A-21 53 534 et DE-A-32 30 612.The present invention relates to network track apparatus railway, and more particularly relates to an elastic fixing device of switchgear rails, in particular a switch needle rail. Devices of this type are notably known, for example DE-A-21 53 534 and DE-A-32 30 612.

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.Railroad switches are usually constituted, for each row 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 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 be "high needle" in the case where the needle rail has the same height as the needle rail, and with "low needle" in the case where the needle rail is lower than the needle rail.

Dans le cas d'un aiguillage à "aiguille basse", le rail-aiguille repose dans 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 in its movable part on sliding bearings. In order to maintain the rail elastic needle against the inner side of the track, it is usually put using a special sliding bearing, which has a recess allowing the insertion of an elastic clip substantially U-shaped, the head of this fastener resting on the inner shoe of the needle rail. Support effort on the skate, which is of the order of 1200daN is obtained by tensioning this fastener by arrangement of the two ends of its branches in two raised housing provided for this purpose and located at the end of the bearing.

Les dispositifs de fixation élastique de rails de ce type existant actuellement présentent, cependant, encore de nombreux inconvénients.Elastic rail fastening devices of this existing type currently, 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 fastener is a sensitive part of the device and must therefore be positioned precisely and without undergo no damage during its installation, in order to avoid deterioration premature, which would lead to an increased risk of rupture putting security seriously at stake.

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. mounting takes place, principle, in five steps, namely the insertion of the fastener in the recess, the setting in place of a branch in the intermediate position, its displacement up to final position, followed by placing the other leg in position intermediate and its displacement to the final position.

Dans la pratique, cette succession d'opérations s'effectue avec quelques difficultés.In practice, this succession of operations is carried out with some difficulties.

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.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 holding over time and to its good operation.

De plus, dans les dispositifs connus le positionnement longitudinal de l'attache dans l'évidement reste assez aléatoire. Or un décalage longitudinal de l'attache consécutif à un positionnement approximatif peut, d'une part, entraíner une usure anormale de celle-ci et augmenter ainsi les risques de rupture et, d'autre part, entraíner une diminution de l'effort de placage du rail contre-aiguille.In addition, in known devices the longitudinal positioning of the attachment in the recess remains fairly random. Now a longitudinal shift of the tie following an approximate positioning can, on the one hand, lead abnormal wear thereof and thus increase the risk of breakage and, on the other hand, cause a decrease in the plating force of the needle rail.

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'aiguillages 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 an elastic fixing device for rails of switches and crossings, in particular of a switch needle rail allowing positioning precise 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 le coussinet comporte, en outre, à l'extrémité de son évidement sous les logements surélevés, un étranglement dont la taille et la forme sont sensiblement égales à celles de l'attache au niveau de ses branches.To this end, the elastic device for fixing the rail of track, in particular of a fixed counter-needle rail of switches cooperating with a movable needle rail capable of moving transversely to the track, these rails resting on a sliding bearing, the needle rail being held on the bearing, on the one hand, on the outside of the track by a fixing means and, on the other hand, on the inside of the track by an elastic fastener substantially in U-shaped, arranged in a recess in the bearing and the ends of the branches penetrate, in the tensioning position of the elastic fastener by by means of a stop ensuring the effort of plating the counter-needle rail on the bearing, in raised housings provided for this purpose in said bearing, is characterized in that the bearing further comprises, at the end of its recess under the raised housing, a constriction whose size and shape are substantially equal to those of the fastener at its branches.

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 partielle 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 ;
  • la figure 3 est une vue en bout détaillée du coussinet de glissement, et
  • la figure 4 est une vue en plan du détail X de la figure 2.
    • The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a partial elevational view in section of a fixing device according to the invention;
  • Figure 2 is a partial plan view of the sliding pad;
  • FIG. 3 is a detailed end view of the sliding bearing, and
  • FIG. 4 is a plan view of the detail X in FIG. 2.

    • 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 2 pouvant se déplacer transversalement à la voie, ces rails reposant sur un coussinet de glissement 3, le rail contre-aiguille 1 étant maintenu sur le coussinet 3, d'une part, du côté extérieur de la voie par un moyen de fixation 4 et, d'autre part. du côté intérieur de la voie par une attache élastique 5 sensiblement en forme de U, disposée dans un évidement 6 du coussinet 3 et dont les extrémités des branches 7 pénètrent, en position de mise en tension de l'attache élastique 5 par l'intermédiaire d'une butée 8 assurant l'effort de placage du rail contre-aiguille 1 sur le coussinet 3, dans des logements surélevés 9 prévus à cet effet dans ledit coussinet 3.Figures 1 and 2 of the accompanying drawings show a device for elastic fastening of a switchgear rail, in particular a counter-needle rail fixed 1 of switches cooperating with a movable needle rail 2 which can move transversely to the track, these rails resting on a sliding bearing 3, the needle rail 1 being held on the bearing 3, on the one hand, on the outside of the track by a fixing means 4 and, on the other hand. on the inside of the track by an elastic fastener 5 substantially in the shape of a U, arranged in a recess 6 of the bearing 3 and the ends of the branches 7 of which penetrate, tensioning position of the elastic fastener 5 by means of a stop 8 ensuring the effort of plating the counter-needle rail 1 on the bearing 3, in raised housings 9 provided for this purpose in said cushion 3.

    Conformément à l'invention et comme le montrent plus particulièrement, à titre d'exemple, les figures 3 et 4 des dessins annexés, le coussinet 3 comporte, en outre, à l'extrémité de son évidement 6 sous les logements surélevés 9, un étranglement 10 dont la taille et la forme sont sensiblement égales à celles de l'attache 5 au niveau de ses branches 7. Cet étranglement 10 est conçu pour assurer au moins une insertion partielle de l'attache 5 jusqu'à sa position longitudinale normale et, de préférence, un positionnement longitudinal parfait de ladite attache 5.According to the invention and as shown more particularly, by way of example, Figures 3 and 4 of the accompanying drawings, the bearing 3 further comprises, at the end of its recess 6 under the raised housing 9, a constriction 10 whose size and shape are substantially equal to those of the fastener 5 at its branches 7. This throttle 10 is designed to ensure at least partial insertion of the fastener 5 to its normal longitudinal position and, preferably, a perfect longitudinal positioning of said fastener 5.

    Ainsi, il est possible de réaliser un bon positionnement longitudinal de l'attache 5 et de l'empêcher de s'engouffrer trop profondément dans l'évidement 6 du coussinet 3, évitant de ce fait tout risque de coincement de ladite attache 5 en position de service.Thus, it is possible to achieve a good longitudinal positioning of fastener 5 and prevent it from rushing too deep into the recess 6 of the pad 3, thereby avoiding any risk of jamming of said fastener 5 in service position.

    A cet effet, selon une autre caractéristique de l'invention, au-dessus de chaque logement 9, il est prévu une pente 11 de positionnement longitudinal de l'attache 5. Ainsi, dans le cas où l'attache 5 n'a pas pu être insérée totalement longitudinalement, ses branches 7 se retrouvent sur ces pentes 11 lors de la mise en tension de l'attache 5, forçant celle-ci à se positionner correctement longitudinalement.To this end, according to another characteristic of the invention, above each housing 9 has a slope 11 for longitudinal positioning of the fastener 5. Thus, in the case where the fastener 5 could not be fully inserted longitudinally, its branches 7 are found on these slopes 11 during the setting in tension of the fastener 5, forcing it to position correctly longitudinally.

    Conformément à une autre caractéristique de l'invention, le coussinet 3 est pourvu, sensiblement en contrebas des logements surélevés 9, de deux logements supplémentaires 12. En outre, la longueur de ces logements 12 correspond avantageusement à celle des logements surélevés 9 augmentée de la longueur des pentes 11 de positionnement longitudinal correspondantes, de sorte qu'elle est telle qu'ils peuvent tout de même recevoir les extrémités des branches 7 de l'attache 5 même si celle-ci n'a pas pu être insérée totalement dans l'évidement 6 du coussinet 3. Ces logements supplémentaires permettent donc un positionnement stable des extrémités des branches de l'attache 5, même dans leur position intermédiaire.In accordance with another characteristic of the invention, the pad 3 is provided, substantially below the raised housing 9, with two additional housings 12. In addition, the length of these housings 12 advantageously corresponds to that of the raised dwellings 9 increased by the length of the corresponding longitudinal positioning slopes 11, so that it is such that they can still receive the ends of the branches 7 of clip 5 even if it could not be fully inserted into the recess 6 of bearing 3. These additional housings therefore allow stable positioning of the ends of the branches of the fastener 5, even in their intermediate position.

    Selon une autre caractéristique de l'invention, le coussinet 3 comprend un bec 13 pourvu de renforcements latéraux permettant la reprises des efforts lors du déversement du rail contre-aiguille 1.According to another characteristic of the invention, the pad 3 includes a spout 13 provided with lateral reinforcements allowing the recovery of forces when the needle rail 1 spills.

    Chaque renforcement du bec 13 est à une distance h2 du patin 14 du rail contre-aiguille 1 inférieure à une distance h1 séparant la tête 15 de l'attache 5 de la surface supérieure de l'évidement 6 du coussinet 3. Il résulte de ce mode de réalisation que la tête 15 de l'attache 5 ne peut en aucun cas se retrouver comprimée entre la surface supérieure de l'évidement 6 du coussinet 3 et le patin 14 du rail contre-aiguille 1 lors du déversement de ce dernier, de sorte que tout coincement de ladite attache dans cette position est évité.Each reinforcement of the spout 13 is at a distance h2 from the shoe 14 of the counter-needle rail 1 less than a distance h1 separating the head 15 from the fastener 5 of the upper surface of the recess 6 of the bearing 3. It results from this mode of realization that the head 15 of the fastener 5 can in no case be found compressed between the upper surface of the recess 6 of the bearing 3 and the shoe 14 of the needle rail 1 when the latter spills, so that all jamming of said fastener in this position is avoided.

    Pour améliorer le déplacement de la tête 15 de l'attache 5 jusque sur le patin 14 du rail 1 lors de sa mise en place dans l'évidement 6 du coussinet 3, ledit coussinet 3 présente, conformément à une autre caractéristique de l'invention, une rampe principale 16 se terminant par deux rampes latérales 17. Ainsi, la tête 15 de l'attache 5 a toujours tendance à être orientée dans un mouvement de soulèvement amenant naturellement sa face inférieure à glisser sans entrave sur la face supérieure du patin 14.To improve the displacement of the head 15 of the fastener 5 up to the shoe 14 of the rail 1 when it is placed in the recess 6 of the bearing 3, said pad 3 has, in accordance with another characteristic of the invention, a main ramp 16 ending in two lateral ramps 17. Thus, the head 15 of the fastener 5 always tends to be oriented in a movement of uplift naturally causing its underside to slide unhindered over the upper face of shoe 14.

    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 d'usure rapide.Thanks to the invention it is possible to produce a fixing device elastic of tracks of tracks, in particular of rails against needles switches allowing precise positioning of these and avoiding all risk of rapid wear.

    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 embodiment described and shown in the accompanying drawings. Modifications are still possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
