Abstract

The train advance unit has an auxiliary bogie (14) that can be lifted, lowered and displaced transversely, and a hydraulic cylinder (15) works the lifting and lowering. A device (36) blocks the bogie when it reaches the transverse position. There are two sections of rail (37,42) to be removed during any work period, respectively below the auxiliary bogie and below the vehicle (1) axle (5), these rail sections traverse the bogie and axle, and there are separate devices (40,41,45,46) to displace each of the sections longitudinally forward.

Description

La présente invention concerne une rame ferroviaire pour le renouvellement de voies ferrées, comprenant un ensemble opératif pourvu de moyens pour enlever les vieux rails, et de moyens pour permettre à l'un au moins des essieux d'avancer sur la voie ferrée déjà privée des rails.The present invention relates to a railway train for the renewal of railway tracks, comprising an operational assembly provided with means for removing the old rails, and means for allowing at least one of the axles to advance on the already deprived track of the rails.

On connaît plusieurs types de véhicules ou rames ferroviaires susceptible d'être déplacés (par leur propres moyens ou attelés derrière des autres rames) sur les voies ferrées, afin de les transférer d'un dépôt à une zone de travail et, après leur arrivée à cette dernière, d'effectuer par des moyens mécanisés les opérations d'enlèvement des rails à remplacer, d'enlèvement des vieilles traverses, de nivellement ou déplacement du ballast, de pose des nouvelles traverses et enfin de pose des nouveaux rails au lieu des précédents. Le support et le guidage d'un ensemble de ce genre peuvent être confiés à la voie préexistante seulement dans la partie antérieure de la rame ferroviaire, parce que, à partir du point où les rails ont été enlevés, le support et le guidage de la voie viennent à manquer. On doit donc prévoir des dispositifs appropriés de support, différents d'un simple essieu ou bogie, qui sont formés habituellement par des supports chenillés s'appuyant sur le ballast, et ne sont pas satisfaisants. On a proposé aussi des dispositifs plus avancés, comportant un patin à rouleaux ou à chenilles qu'on dispose au-dessous de l'essieu du véhicule et qui glisse sur les vieillés traverses encore posées, mais même dans ce cas on rencontre des difficultés dues au fait que le déplacement du patin a lieu sous la charge du poids tout entier agissant sur l'essieu.Several types of rail vehicles or trains are known that can be moved (by their own means or harnessed behind other trains) on the railways, in order to transfer them from a depot to a work area and, after arriving at the latter, to carry out by mechanical means the operations of removing the rails to be replaced, removing the old sleepers, leveling or moving the ballast, laying new sleepers and finally laying new rails instead of the previous ones . The support and guidance of such an assembly can be entrusted to the pre-existing track only in the front part of the train set, because, from the point where the rails have been removed, the support and guidance of the track are running out. It is therefore necessary to provide suitable support devices, different from a simple axle or bogie, which are usually formed by tracked supports resting on the ballast, and are not satisfactory. More advanced devices have also been proposed, comprising a roller or track shoe which is placed below the axle of the vehicle and which slides on the aged sleepers still laid, but even in this case we encounter difficulties due the fact that the movement of the shoe takes place under the load of the entire weight acting on the axle.

Le but de la présente invention est de perfectionner les rames ferroviaires connues destinées à la fonction décrite, en prevoyant pour elles un dispositif de support et de guidage de l'avancement qui permette à la rame de procéder sur la voie ferrée déjà privée des rails, en suivant le tracé correct, et qui soit exempt des inconvénients des dispositifs connus, ou qui les présente en mesure plus réduite.The aim of the present invention is to improve the known railway trainsets intended for the function described, by providing for them a device for supporting and guiding the advance which allows the trainset to proceed on the railway track already deprived of the rails, by following the correct route, and which is free from the drawbacks of known devices, or which presents them in a more reduced measure.

La rame ferroviaire selon la présente invention, comprenant un ensemble opératif pourvu de moyens pour enlever les vieux rails, et de moyens pour permettre à l'un au moins des essieux d'avancer sur la voie ferrée déjà privée des rails, est caractérisée principalement en ce que lesdits moyens permettant à un essieu d'avancer sur la voie ferrée déjà privée des rails comprennent:

  • - un bogie auxiliaire qui peut être soulevé et abaissé et susceptible aussi d'un déplacement transversal;
  • - des moyens pour commander le soulevement et l'abaissement dudit bogie auxiliaire:
  • - des moyens pour bloquer ledit bogie auxiliaire dans la position transversale atteinte;
  • - des premiers et des seconds tronçons de rail susceptibles d'être disposés, pendant les périodes de travail sur les traverses, respectivement au-dessous du bogie auxiliaire et au-dessous de l'essieu considéré, pour être parcourus par eux, et des premiers et des second moyens pour deplacer longitudinalement en avant par cycles alternatifs lesdits premiers et seconds tronçons de rail.
The train set according to the present invention, comprising an operating assembly provided with means for removing the old rails, and means for allowing at least one of the axles to advance on the railway track already deprived of the rails, is mainly characterized by that said means allowing an axle to advance on the already deprived track of rails include:
  • - an auxiliary bogie which can be raised and lowered and also capable of transverse displacement;
  • - means for controlling the raising and lowering of said auxiliary bogie:
  • - Means for locking said auxiliary bogie in the transverse position reached;
  • - first and second sections of rail capable of being arranged, during the periods of work on the sleepers, respectively below the auxiliary bogie and below the axle in question, to be traversed by them, and first and second means for moving longitudinally forward by alternating cycles said first and second rail sections.

Grâce à ces caractéristiques, l'ensemble opératif de la rame ferroviaire selon l'invention (qui peut être précédé, comme d'habitude, par des wagons de stockage qui transportent les matériaux nouveaux à poser et qui sont destinés à recevoir les vieux matériaux enlevés, et suivi par des autres véhicules portant des moyens opératifs), avance, par un ou plusieurs essieux qui précèdent l'essieu considéré, sur la voie à renouveler, précédemment libérée des organes de fixation, enlève les vieux rails et avance par l'essieu considéré sur les vieilles traverses encore posées, avec l'interposition de tronçons de rails qui prennent appui sur les traverses, ou bien sur les supports pour rail quand ceux-ci sont présents sur les traverses, et sont guidés par ces derniers, de sorte que l'ensemble résulte soutenu correctement et suit fidèlement le tracé préexistant. L'avancement de chaque tronçon de rail est effectué lors qu'aucune charge n'est appliquée sur l'essieu correspondant, respectivement sur le bogie auxiliaire, et par conséquent on ne rencontre aucun danger de difficultés à l'avancement des tronçons de rail, ni de déplacement des traverses.Thanks to these characteristics, the operational assembly of the railway train according to the invention (which can be preceded, as usual, by storage wagons which transport the new materials to be laid and which are intended to receive the old materials removed , and followed by other vehicles carrying operational means), advances, by one or more axles which precede the axle in question, on the track to be renewed, previously freed from the fasteners, removes the old rails and advances by the axle considered on old sleepers still laid, with the interposition of sections of rails which bear on the sleepers, or else on the rail supports when these are present on the sleepers, and are guided by them, so that the whole results correctly supported and faithfully follows the pre-existing layout. The advancement of each section of rail is carried out when no load is applied to the corresponding axle, respectively on the auxiliary bogie, and consequently there is no danger of difficulties in advancing the sections of rail, nor of displacement of the sleepers.

De préférence, en outre, lesdits moyens permettant à l'un au moins des essieu d'avancer sur la voie ferrée déjà privée des rails comprennent aussi des moyens détecteurs disposés pour détecter l'approche dudit bogie auxiliaire et dudit essieu aux extrémités antérieures et, respectivement, postérieures de la course utilé sur lesdits tronçons de rail, et des moyens de coordination du fonctionnement dedites parties de la rame, controlés par lesdits moyens détecteurs et disposés pour provoquer, alternativement pour ledit essieu et pour ledit bogie auxiliaire, le transfert de la charge sur l'autre d'eux et l'avancement de ses propres tronçons de rail, ainsi que pour provoquer le blocage du déplacement transversal du bogie auxiliaire seulement pendant les périodes où il est soumis à la charge.Preferably, in addition, said means allowing at least one of the axles to advance on the already deprived track of the rails also comprise detector means arranged to detect the approach of said auxiliary bogie and said axle at the anterior ends and, respectively, posterior to the travel used on said sections of rail, and means for coordinating the operation of parts of the train, controlled by said detector means and arranged to cause, alternately for said axle and for said auxiliary bogie, the transfer of the load on the other of them and the advancement of its own sections of rail, as well as to cause the blocking of the transverse displacement of the auxiliary bogie only during the periods when it is subjected to the load.

Grâce à ces caractéristiques ultérieures, le fonctionnement des moyens de support et de guidage de l'avancement de la rame ferroviaire resulte complètement automatique et n'engage pas l'action ni le contrôle des opérateurs.Thanks to these subsequent characteristics, the operation of the means for supporting and guiding the advancement of the railway train results in fully automatic operation and does not involve the action or the control of the operators.

Ces particularités et d'autres et les avantages de l'objet de l'invention ressortiront plus clairement de la suivante description d'une forme de réalisation donné à titre d'exemple non limitatif et représentée schématiquement dans le dessin annexé, dans lequel:These and other particularities and advantages of the subject of the invention will emerge more clearly from the following description of an embodiment given by way of nonlimiting example and represented diagrammatically in the appended drawing, in which:

Une rame ferroviaire pour le renouvellement de voies ferrées, selon la présente invention, comprend généralement un ensemble opératif selon la figure 1 (prédisposé pour avancer de la droite vers la gauche suivant le dessin), des moyens opératifs ultérieurs connus en soi, montés sur des wagons non représentés, qui suivent l'ensemble opératif, et un certain nombre de wagons de stockage destinés à porter les nouveaux matériaux qui doivent être posés et à recevoir les vieux matériaux qui ont été enlevés, disposés (dans le sens d'avancement de la rame ferroviaire) devant l'ensemble opératif représenté dans la figure 1.A railway train for the renewal of railways, according to the present invention, generally comprises an operating assembly according to Figure 1 (predisposed to advance from right to left according to the drawing), subsequent operating means known per se, mounted on wagons not shown, which follow the operational assembly, and a certain number of storage wagons intended to carry the new materials which must be laid and to receive the old materials which have been removed, disposed (in the direction of advancement of the train) in front of the operational assembly shown in Figure 1.

L'ensemble opératif selon la figure 1 comprend deux véhicules définis par leurs châssis 1 et 2, qui sont réciproquement articulés de façon sphériqué en 3. Le châssis du véhicule la un premier essieu 4 et un deuxième essieu 5 (qui pourraient être remplacés par des bogies correspondants), tandis que le châssis du véhicule 2 s'appuie antérieurement, à travers l'articulation 3, sur le châssis 1, et postérieurement sur un propre essieu 6 (qui pourrait lui-aussi être remplacé par un bogie).The operating assembly according to FIG. 1 comprises two vehicles defined by their chassis 1 and 2, which are reciprocally articulated spherically at 3. The vehicle chassis has a first axle 4 and a second axle 5 (which could be replaced by corresponding bogies), while the chassis of the vehicle 2 rests anteriorly, through the articulation 3, on the chassis 1, and later on its own axle 6 (which could also be replaced by a bogie).

Le châssis 1 du premier véhicule porte, dans sa partie supérieure, un transporteur 7 reliée à un dépôt 8 pour les vieilles traverses enlevées, un dépôt 9 pour les nouvelles traverses à poser, et une voie de service 10 pour un transporteur à portail (connu en soi et non représenté destiné à la manutention des matériaux entre les dépôts 8 et 9 et les wagons de stockage disposés à précédér l'ensemble opératif 1 - 2. De plus, le châssis 1 porte, dans sa partie inférieure, un groupe moteur II, généralement un moteur diesel actionnant une centrale hydrodynamique et un générateur électrique pour l'alimentation des différents organes opératifs de l'ensemble, un châssis 12 pourvu de pinces à rouleaux 13 disposées (d'une manière connue en soi) pour soulever et éloigner les vieux rails qui doivent être enlevés, des traverses situées au-dessous de ces rails, et un bogie auxiliaire 14 (qui peut être soulevé au moyens d'un cylindre hydraulique 15) faisant partie des moyens destinés à permettre au deuxième essieu 5 d'avancer sur les vieilles traverses déjà dépourvues des rails, ces moyens étant décrits plus en détail par la suite avec référence à la figure 2.The chassis 1 of the first vehicle carries, in its upper part, a transporter 7 connected to a depot 8 for the old removed sleepers, a depot 9 for the new sleepers to be laid, and a service track 10 for a portal transporter (known per se and not shown intended for the handling of materials between depots 8 and 9 and the storage wagons arranged in front of the operating unit 1 - 2. In addition, the chassis 1 carries, in its lower part, an engine group II , generally a diesel engine actuating a hydrodynamic power station and an electric generator for the supply of the different operative members of the assembly, a chassis 12 provided with roller clamps 13 arranged (in a manner known per se) to lift and move the old rails which have to be removed, sleepers located below these rails, and an auxiliary bogie 14 (which can be lifted by means of a hydraulic cylinder 15) being part of the means intended to allow the uxième axle 5 to advance on the old sleepers already deprived of the rails, these means being described in more detail below with reference to FIG. 2.

Le châssis 2 du deuxième véhicule porte dans sa partie supérieure un transporteur 16, relié au transporteur 7 du premier véhicule, pour les vieilles trayerses enlevées, un transporteur 17, relié au dépôt 9 du premier véhicule, pour les nouvelles traverses à poser, un parapetestrade 18 pour le contrôle de la pose et pour des interventions éventuelles sur les mécanismes respectifs, une cabine opérative 19 et un dépôt 20 pour des traverses spéciales à poser dans des endroits particuliers, comme par exemple aux passages à niveau. Le châssis 2 porte, dans sa partie inférieure, un dispositif 21 d'enlèvement des vieilles traverses qui alimentele transporteur 16, un soc 22 pour le nivellement ou l'enlèvement du ballast, un groupe 23 de, pose des nouvelles traverses, un distributeur 24 pour les traverses spéciales venant du dépôt 20, et un support chenillé 25. Ce dernier ensemble, qui est soulevé pour la marche d'approche sur la voie quand l'essieu 6 est actif, est abaissé (jusqu'à la position représentée) pendant le travail et permet au deuxième véhicule 2 de procéder en s'appuyant sur les nouvelles traverses posées, encore dépourvues des rails (ou, selon unc alternative possible, latéralement auxdites traverses).The chassis 2 of the second vehicle carries in its upper part a transporter 16, connected to the transporter 7 of the first vehicle, for the old trayerses removed, a transporter 17, connected to the depot 9 of the first vehicle, for the new sleepers to be installed, a parapetestrade 18 for checking the installation and for possible interventions on the respective mechanisms, an operating cabin 19 and a depot 20 for special sleepers to be placed in particular places, such as at level crossings. The chassis 2 carries, in its lower part, a device 21 for removing the old sleepers which feeds the conveyor 16, a ploughshare 22 for leveling or removing the ballast, a group 23 of, laying new sleepers, a distributor 24 for special sleepers coming from depot 20, and a tracked support 25. This latter assembly, which is raised for approaching on the track when axle 6 is active, is lowered (to the position shown) for the work and allows the second vehicle 2 to proceed by relying on the new sleepers laid, still devoid of the rails (or, according to a possible alternative, laterally to said sleepers).

L'ensemble opératif décrit agit en procédant en marche continué vers la gauche suivant la figure 1, en roulant au moyen de l'essieu 4 sur les vieux rails déboulonnés, en soulevant et en enlevant les vieux rails par les moyens 12 - 13 tandis que les vieilles traverses restent posées sur le ballast, en roulant sur ces vieilles traverses (comme décrit par la suite) au moyen de l'essieu 5 et du bogie auxiliaire 14, en enlevant au moyen du dispositif d'enlévement 21 les vieilles traverses que les transporteurs 16 et 7 envoient au dépôt 8, en nivelant cu en déplaçant le ballast au moyen du soc 22 et des moyens opératifs associés, et en posant, par les moyens 23 ou 24, des nouvelles traverses sur lesquelles l'ensemble avance au moyen du support chenillé 25. Les opérations ultérieures (pose des nouveaux rails, compactage de ballast, etc.) sont effectuées par des moyens opératifs successifs (non représentés).The operating assembly described acts by proceeding in continuous movement to the left according to FIG. 1, by rolling by means of the axle 4 on the old unbolted rails, by lifting and removing the old rails by means 12 - 13 while the old sleepers remain placed on the ballast, rolling on these old sleepers (as described below) by means of the axle 5 and the auxiliary bogie 14, removing by means of the removal device 21 the old sleepers that the conveyors 16 and 7 send to depot 8, leveling cu by moving the ballast by means of the ploughshare 22 and associated operating means, and by placing, by means 23 or 24, new sleepers on which the assembly advances by means of the tracked support 25. Subsequent operations (laying new rails, compacting ballast, etc.) are carried out by successive operating means (not shown).

Faisant référence à la figure 2, le dispositif permettant au deuxième essieu 5 du véhicule 1 d'avancer sur les vieilles traverses, qui dans l'endroit dudit essieu sont déjà privées des vieux rails enlevés par les moyens 12 - 13, comprend un bogie auxiliaire soulevable et abaissable au moyen d'un cylindre hydraulique 15. Dans la position soulevée, le bogie 14 ne touche pas les rails et ne géene pas la marche de la rame ferroviaire, tandis que dans la position abaissée il peut décharger de l'essieu 5 le poids du châssis 1, absorbé par le bogie 14 par l'intermédiaire du cylindre 15 soumis à pression, ou bien s'appuyer simplement sans charge sur les rails, quand le cylindre 15 n'est pas sous pression. Le soulèvement et l'abaissement du bogie 14 sont guidés par un cinématisme approprié, par exemple un parallélogramme 35; en outre, le bogie 14 est en condition d'effectuer un déplacement transversal qui, du reste, peut être bloqué par un cylindre hydraulique 36. Pendant les périodes de travail, sur les vieilles traverses, au-dessous du bogie 14, sont posés des courts tronçons de rail 37 qui coopèrent avec le bogie 14 au moyen d'un détecteur de position 38 et qui. au moyen d'un système de leviers 40, peuvent être déplacés longitudinalement par un cylindre hydraulique 41. D'une manière analogue, pendant les périodes ne travail, des tronçons de rail 42, pourvus de détecteurs de position 43 et 44, sont posés sur les vieilles traverses au-dessous de l'essieu 5 et, au moyen d'un système de leviers 45, peuvent être déplacés longitudinalement par un cylindre hydraulique 46.Referring to Figure 2, the device allowing the second axle 5 of the vehicle 1 to advance on the old sleepers, which in the location of said axle are already deprived of the old rails removed by the means 12 - 13, comprises an auxiliary bogie lifting and lowering by means of a hydraulic cylinder 15. In the raised position, the bogie 14 does not touch the rails and does not interfere with the running of the railway train, while in the lowered position it can unload from the axle 5 the weight of the chassis 1, absorbed by the bogie 14 via the cylinder 15 subjected to pressure, or else simply bear without load on the rails, when the cylinder 15 is not under pressure. The raising and lowering of the bogie 14 is guided by an appropriate kinematism, for example a parallelogram 35; in addition, the bogie 14 is able to perform a transverse movement which, moreover, can be blocked by a hydraulic cylinder 36. During the working periods, on the old sleepers, below the bogie 14, are placed short sections of rail 37 which cooperate with the bogie 14 by means of a position detector 38 and which. by means of a system of levers 40, can be moved longitudinally by a hydraulic cylinder 41. In a similar manner, during periods of work, sections of rail 42, provided with position detectors 43 and 44, are placed on the old sleepers below the axle 5 and, by means of a system of levers 45, can be moved longitudinally by a hydraulic cylinder 46.

Ce dispositif fonctionne de la manière suivante. Pendant l'avancement de travail de la rame ferroviaire, les tronçons de rail 37 et 42 sont disposés, respectivement, au-dessous de l'essieu 5 et au-dessous de bogie 14 et prennent appui sur les plaques porte-rails des traverses situées au-dessous, qui les guident suivant le tracé de la voie. Dans les cas où l'armement ne prévoit pas l'emploi de plaques, l'appui des tronçons de rails 37 et 42 a lieu directement sur la partie supérieure des traverses. Dans une première phase, l'essieu 5 (sur lequel dans cette phase s'applique le poids du châssis 1) avance sur les tronçons de rail 42, qui restent immobiles par rapport aux traverses situées au-dessous. Le cylindre 15 est inactif et par conséquent le bogie 14 n'a pas de charge, pendant cette phase d'avancement, dans laquelle la charge est appliquée sur l'essieu 5, le cylindre 41 est actif et il fait avancer les tronçons de rail 37 par rapport aux traverses situées au-dessous et par rapport au bogie 14, ce qui ne présente pas de difficultés car le bogie 14 n'est pas chargé. Cet avancement des tronçons de rail 37 par rapport au bogie 14 se continue jusqu'au moment où l'activité du cylindre 41 est interrompue par le détecteur de position 44. Celui-ci active aussi le cylindre 15, lequel alors transmet le poids du châssis 1 au bogie 14, et décharge par conséquent l'essieu 5, et active aussi le cylindre 46. A ce moment-là commence une seconde phase, dans laquelle le bogie 14 (sur lequel agit maintenant le poids du châssis 1) avance sur les tronçons de rail 37, qui restent immobiles par rapport au traverses situés au-dessous. Pendant cette phase d'avancement, dans laquelle le bogie 14 est soumis à la charge, le cylindre 46 qui a été activé fait avancer les tronçons de rail 42 par rapport aux traverses situés au-dessous et par rapport à l'essieu 5, ce qui ne présente pas de difficultés car l'essieu 5 n'est pas chargée. Cet avancement des tronçons de rail 42 par rapport à l'essieu 5, et la phase d'avancement du véhicule prenant appui sur le bogie 14, se continuent jusqu'au moment où les détecteurs de position 43 et 38 interrompent l'activité du cylindre 46 désactivent le cylindre 15 et activent le cylindre 41; par conséquent le poids du châssis 1 recommence à charger l'essieu 5. A ce point, le cycle de fonctionnement est terminé, et les deux phases décrites continuent à se répéter d'une manière cyclique, en permettant un avancement continu du véhicule. L'avancement sur les traverses privées de rails a donc lieu par cycles alternatifs de déplacement en avant des tronçons de rail 37 et 42, tandis que le poids du véhicule qui avance agit toujours sur les tronçons de rail stationnaires, et les tronçons de rails qui sont en train de se déplacer en avant sont toujours ceux qui se trouvent au-dessous d'un moyen de support qui dans cette phase n'est pas chargé.This device operates in the following manner. During the working progress of the railway train, the rail sections 37 and 42 are arranged, respectively, below the axle 5 and below the bogie 14 and bear on the rail-carrying plates of the sleepers located below, which guide them along the route of the track. In cases where the armament does not provide for the use of plates, the support of the rail sections 37 and 42 takes place directly on the upper part of the sleepers. In a first phase, the axle 5 (on which in this phase the weight of the chassis 1 is applied) advances on the rail sections 42, which remain stationary relative to the crosspieces situated below. The cylinder 15 is inactive and therefore the bogie 14 has no load, during this advancement phase, in which the load is applied to the axle 5, the cylinder 41 is active and it advances the sections of rail 37 with respect to the cross members located below and with respect to the bogie 14, which does not present any difficulties since the bogie 14 is not loaded. This advancement of the rail sections 37 relative to the bogie 14 continues until the activity of the cylinder 41 is interrupted by the position detector 44. This also activates the cylinder 15, which then transmits the weight of the chassis 1 to the bogie 14, and consequently unloads the axle 5, and also activates the cylinder 46. At this time begins a second phase, in which the bogie 14 (on which the weight of the chassis 1 now acts) advances on the sections of rail 37, which remain stationary relative to the sleepers located below. During this advancement phase, in which the bogie 14 is subjected to the load, the cylinder 46 which has been activated advances the rail sections 42 with respect to the crosspieces situated below and with respect to the axle 5, this which presents no difficulties because the axle 5 is not loaded. This advancement of the rail sections 42 relative to the axle 5, and the advancement phase of the vehicle resting on the bogie 14, continue until the position detectors 43 and 38 interrupt the activity of the cylinder. 46 deactivate the cylinder 15 and activate the cylinder 41; therefore the weight of the chassis 1 begins to load the axle 5. At this point, the operating cycle is completed, and the two phases described continue to repeat themselves in a cyclic manner, allowing continuous advancement of the vehicle. Advancement on the private rail sleepers therefore takes place in alternating cycles of displacement in front of the rail sections 37 and 42, while the weight of the advancing vehicle always acts on the stationary rail sections, and the rail sections which are moving forward are always those which are below a support means which in this phase is not loaded.

Le cylindre 36 est connecté de sorte à laisser libre le déplacement transversal du bogie 14 tandis que le poids du véhicule agit sur l'essieu 5, et à bloquer ce déplacement latéral quand le poids du véhicules est transféré sur le bogie 14. De cette manière, le bogie 14 a la possibilité d'adapter sa propre position transversale, en fonction de la courbure locale du tracé de la voie, pendant toute la période dans laquelle la position transversale du véhicule est définie par l'essieu 5, et maintient ensuite inchangée cette position transversale pendant la période dans laquelle le bogie 14 supporte la charge. Dans le but de laisser le plus possible à l'essieu la fonction de contrôler la position transversale du véhicule, de préférence la course d'avancement des tronçons de rail 42 est considérablement plus grande de celle des tronçons de rail 37, et la charge est transféré sur le bogie 14 seulement dans la période strictement nécessaire pour le déplacement des tronçons de rail 42. Par exemple, la longueur de déplacement des tronçons de rail 42 peut être de 40 cm, et la longueur de déplacement des tronçons de rail 37 peut être de 20 cm.The cylinder 36 is connected so as to allow free the transverse movement of the bogie 14 while the weight of the vehicle acts on the axle 5, and to block this lateral movement when the weight of the vehicles is transferred to the bogie 14. In this way , the bogie 14 has the possibility of adapting its own transverse position, as a function of the local curvature of the track layout, during the whole period in which the transverse position of the vehicle is defined by the axle 5, and then maintains unchanged this transverse position during the period in which the bogie 14 supports the load. In order to leave as much as possible to the axle the function of controlling the transverse position of the vehicle, preferably the advance travel of the rail sections 42 is considerably greater than that of the rail sections 37, and the load is transferred to the bogie 14 only in the period strictly necessary for the movement of the rail sections 42. For example, the length of movement of the rail sections 42 can be 40 cm, and the length of movement of the rail sections 37 can be 20 cm.

Le dispositif selon l'invention a été décrit en relation avec le deuxième essieu 5 d'un véhicule 1 à deux essieux 4 et 5, pourvu de moyens 12,13 pour enlever les vieux rails disposés entre les deux essieux, et suivi par un autre véhicule 2 à un seul essieu 6. Cependant, on doit entendre qu'un dispositif similaire peut être employé avec avantage aussi pour supporter et guider l'essieu 6 du deuxième véhicule, au lieu du support chenillée 25. En outre, dans les cas où les moyens 12, 13 pour enlever les vieux rails ne sont pas disposés après l'essieu 4 du véhicule 1, mais sur un wagon qui le précède dans la rame ferroviaire, un dispositif comme celui qui a été décrit peut être aussi appliqué pour soutenir et guider le premier essieu 4 du véhicule 1. Dans ce cas on peut augmenter l'opérativité de la machine en réduisant à des niveaux négligeables les tensions intérieures induites dans les rails pendant 1 l'opération d'enlèvement des ces rails.The device according to the invention has been described in relation to the second axle 5 of a vehicle 1 with two axles 4 and 5, provided with means 12, 13 for removing the old rails arranged between the two axles, and followed by another vehicle 2 with a single axle 6. However, it should be understood that a similar device can also be advantageously used to support and guide the axle 6 of the second vehicle, instead of the tracked support 25. Furthermore, in cases where the means 12, 13 for removing the old rails are not arranged after the axle 4 of the vehicle 1, but on a wagon which precedes it in the railway train, a device like that which has been described can also be applied to support and guide the first axle 4 of the vehicle 1. In this case, the operation of the machine can be increased by reducing the internal tensions induced in the rails to negligible levels during the removal operation of these rails.

A la fin de l'opération de remplacement d'une section de voie, les tronçons de rail 37 et 42 pourraient être enlevés. Cependant, de préférence, les tronçons de rail 42 sont préparés pour être laissés en oeuvre, en les fixant aux plaques ou aux traverses située au-dessous par les organes normaux de fixation, et en les reliant, au moyen des éclisses habituelles, d'un côté à la vieille voie encore non renouvelé, et de l'autre côté aux nouveaux rails qui viennent d'être installés, en établissant ainsi 17 continuité nécessaire pour le passage des rames ferroviaires sur la voie. Cette opération facilite de façon substantielle la suspension et la reprise de l'activité de la rame ferroviaire de renouvellement sur une voie qui doit rester ouverte au trafficAt the end of the track section replacement operation, the rail sections 37 and 42 could be removed. However, preferably, the rail sections 42 are prepared to be left in use, by fixing them to the plates or to the crosspieces situated below by the normal fixing members, and by connecting them, by means of the usual fishplates, one side to the old track which has not yet been renewed, and the other side to the new rails which have just been installed, thereby establishing 17 continuity necessary for the passage of the railway trains on the track. This operation substantially facilitates the suspension and resumption of activity on the railway renewal train on a track which must remain open to traffic.

Le dispositif décrit présente une sécurité de fonctionnement considérablement supérieure a celle des dispositifs connus, même de ceux plus avancés dans lesquels au-dessous de l'essieu du véhicule est disposé un patin à rouleaux ou à chenilles, qui est destiné à coulisser sur les traverses sous la charge toute entière à laquelle est soumis l'essieu du véhicule, et qui peut, de ce fait, encontrer des difficultés, des résistances ou des empêchements à l'avancement, ou bien il peut déplacer les vieilles traverses, avec le résultat de bouleverser la piste sur laquelle le patin doit coulisser.The device described presents a considerably greater operating safety than that of known devices, even of those more advanced in which below the axle of the vehicle is arranged a roller or track shoe, which is intended to slide on the sleepers under the entire load to which the axle of the vehicle is subjected, and which can, therefore, encounter difficulties, resistances or impediments to advancement, or else it can displace the old sleepers, with the result of upsetting the track on which the skate must slide.

On doit entendre que la rame ferroviaire selon l'invention peut présenter toutes les caractéristiques décrites ou bien aussi seulment une partie de celles-ci, selon les applications particulières auxquelles elle est destiné. Des différentes modifications peuvent être appliquées aux détails décrits, et toutes les parties et les groupes peuvent être remplacés par leurs équivalents techniques.It should be understood that the railway train according to the invention can have all the characteristics described or even just a part of them, depending on the particular applications for which it is intended. Different modifications can be applied to the details described, and all parts and groups can be replaced by their technical equivalents.
