Abstract

The bogie consists of a fixed and non-pivoting axle (1) with sliding bands (2) and support housings (16) at each end. Each support housing has a cavity which allows the axle to move vertically and contains a mechanism to permit or prevent such movement. The wheels (4) are mounted on the bands (2), which are able to slide along the axle and are locked relative to the support housings by mechanisms (18). The two wheels are also linked by a closed kinematic circuit with couplings linked by telescopic toothed mechanisms.

Description

Les véhicules ferroviaires circulent sur deux poutres en acier (rails) parallèles entre elles et ayant un écartement constant, qui constituent la voie ou le chemin de roulement pour les roues du train.Railway vehicles run on two steel beams (rails) parallel to each other and having a constant spacing, which constitute the track or the raceway for train wheels.

L'écartement entre les rails est un paramètre essentiel au moment de concevoir un train, car, outre qu'il a de l'influence sur la dynamique de celui-ci, conditionne son exploitation à des trajets de voie ayant exclusivement l'écartement pour lequel il a été conçu. Ce fait ne supposerait aucun inconvénient si ce n'était du fait qu'il existe, à l'heure actuelle, différentes configurations de voie, en ce qui concerne l'écartement entre les rails qui la forment. De fait, même dans un même pays, il est habituel de rencontrer des voies ayant deux - voire davantage - écartements différents.The spacing between the rails is an essential parameter when designing a train because, in addition to having an influence on its dynamics, conditions its operation on track paths having exclusively the gauge for which it was designed. This fact would not cause any inconvenience were it not for the fact that it There are currently different track configurations, with regard to the spacing between the rails which form it. In fact, even in the same country, it is usual to encounter paths with two - or more - different spacings.

Cette situation suppose un sérieux inconvénient dans l'exploitation des véhicules, car leur caractère opérationnel est limité à des trajets de voie dont l'écartement sera exclusivement celui pour lequel ils ont été conçus.This situation implies a serious drawback in the operation of vehicles, because their operational nature is limited to track journeys whose the spacing will be exclusively that for which they were designed.

Traditionnellement, ce problème était évité au moyen d'opérations coûteuses de changement d'essieux ou de bogies des véhicules qui exigeraient une grande quantité de temps et, par conséquent, une grande perte de compétitivité face à d'autres moyens de transport.Traditionally, this problem has been avoided through operations costly to change axles or bogies of vehicles that would require large amount of time and therefore a great loss of competitiveness in the face of other means of transportation.

Déjà lors de la première moitié de ce siècje, on commença à travailler sur des systèmes qui réduiraient aussi bien les temps que les coûts que supposait le passage de véhicules entre deux voies ayant un écartement différent entre leurs rails.Already during the first half of this century, we began to work on systems that would reduce both the time and the cost involved in switching of vehicles between two tracks having a different spacing between their rails.

À la suite de ces recherches, plusieurs systèmes sont nés qui, à une échelle plus ou moins grande, essayaient d'automatiser le processus de changement de voie grâce au repositionnement des roues du train à son passage dans une installation fixe conçue dans ce but. As a result of this research, several systems were born which, on a scale larger or smaller, were trying to automate the lane change process by repositioning the wheels of the train as it passes through a fixed installation designed for this purpose.

En ce qui concerne l'état du matériel roulant ayant la capacité de circuler sur des voies ayant un écartement différent, il y a plusieurs brevets qui traitent du sujet et sont fondés sur différents concepts, tels que, par exemple:

  • ceux qui maintiennent un essieu fixe sur lequel glissent les roues avec leurs frettes
  • ceux qui déplacent l'ensemble formé par la roue, un demi-essieu et des roulements para rapport à un châssis fixe de bogie ou d'essieu.
  • Ceux qui incorporent une suspension indépendante dans chaque ensemble de roue
  • ceux qui déplacent une partie des châssis du bogie...
Regarding the condition of rolling stock having the capacity to run on tracks with a different gauge, there are several patents which deal with the subject and are based on different concepts, such as, for example:
  • those who maintain a fixed axle on which the wheels slide with their frets
  • those that move the assembly formed by the wheel, a half-axle and bearings relative to a fixed bogie or axle chassis.
  • Those who incorporate independent suspension into each wheel set
  • those who move part of the bogie chassis ...

En ce qui concerne les bogies de roulement à empattement variable, qui maintiennent un essieu fixe (type du bogie faisant l'objet de l'invention), l'invention présente les avantages suivants:

  • Il s'agit d'un bogie où le verrouillage des roues n'est pas basé sur des verrous mais sur de simples pitons dont le verrouillage/déverrouillage s'effectue par gravité, ce qui suppose les avantages suivants:
    • Installation fixe simple dans laquelle des actionnements pour ces verrous ne sont pas nécessaires, n'en disposant pas.
    • Le système proprement dit (monté sur le bogie) ne comprend pas de mécanismes qui sont toujours sujets à des défaillances possibles.
    • Les problèmes possibles d'infraction du gabarit inférieur de la voie de la part des dispositifs de verrouillage sont éliminés.
  • Le bogie comprend des éléments flexibles sur sa chaíne cinématique, qui empêchent la transmission d'efforts provenant de désalignements dus à des jeux résiduels faibles voire aux efforts roue/rail eux-mêmes.
  • La caisse-support extrême comprend un réa d'appui, qui agit lorsque le véhicule passe par l'installation fixe de changement d'écartement de voie. Cet élément, en roulant, évite les usures et les efforts qui se produiraient dans le cas où l'on disposerait d'éléments d'appui coulissant.
  • La position des disques de frein est indépendante de l'écartement de la voie sur laquelle on roule, ce qui suppose un facteur additionnel à la simplicité du système et, donc, à sa sûreté et sa fiabilité.
  • Le bogie est valable aussi bien pour les arbres moteurs que pour les remorques sans autre modification que celle de remplacer le réducteur par un arbre creux. Celui-ci remplit la fonction de l'arbre creux du réducteur en ce qui concerne le fait de forcer la rotation simultanée des deux roues de l'essieu et, par conséquent, de garantir l'effet de guidage de l'ensemble de l'essieu.
  • Le corps à essieu fixe, sur lequel est monté le système, est un élément qui, n'étant pas rotatif, comme sur les essieux conventionnels, a un comportement à la fatigue bien plus favorable que ceux-ci , car, pour des cycles de charge identiques, les rangs des tensions qu'il supporte sont inférieurs.
  • L'ensemble de l'essieu est étanche, ce qui garantit son isolement face à des agents extérieurs et, par conséquent, sa durabilité.
As regards variable-wheelbase rolling bogies, which maintain a fixed axle (type of bogie which is the subject of the invention), the invention has the following advantages:
  • It is a bogie where the locking of the wheels is not based on locks but on simple pegs whose locking / unlocking is effected by gravity, which implies the following advantages:
    • Simple fixed installation in which actuations for these locks are not necessary, without having one.
    • The system itself (mounted on the bogie) does not include mechanisms which are always subject to possible failures.
    • The possible problems of breach of the lower gauge of the track by the locking devices are eliminated.
  • The bogie includes flexible elements on its kinematic chain, which prevent the transmission of forces coming from misalignments due to small residual clearances or even to the wheel / rail forces themselves.
  • The extreme support box includes a support sheave, which acts when the vehicle passes through the fixed track gauge change facility. This element, while rolling, avoids the wear and the forces which would occur in the case where sliding support elements are available.
  • The position of the brake discs is independent of the spacing of the track on which you are driving, which supposes an additional factor to the simplicity of the system and, therefore, to its safety and reliability.
  • The bogie is valid both for the drive shafts and for the trailers without any other modification than that of replacing the reduction gear by a hollow shaft. This fulfills the function of the hollow shaft of the reducer with regard to forcing the simultaneous rotation of the two wheels of the axle and, consequently, guaranteeing the guiding effect of the whole of the axle.
  • The body with fixed axle, on which the system is mounted, is an element which, not being rotatable, like on conventional axles, has a much more favorable fatigue behavior than these, because, for cycles of identical loads, the ranks of the voltages it supports are lower.
  • The entire axle is waterproof, which guarantees its isolation from external agents and, therefore, its durability.

Indiquer enfin que les clés du succès d'un système de changement automatique de l'écartement de la voie sont sa fiabilité et le fait de pouvoir le maintenir à un coût bas. En général, un système de changement d'écartement de voie doit être fiable dans le sens où il doit non seulement garantir le positionnement correct des roues à leur passage par l'installation de changement d'écartement, mais que cette position doit, en outre, être maintenue pendant le roulement du train quelle qu'en soit la condition de circulation. Une grande fiabilité et le fait de pouvoir le maintenir à un coût bas sont les facteurs qui vont déterminer la viabilité économique, car cela aura une conséquence directe sur la compétitivité du train face à d'autres moyens de transport.Finally, indicate that the keys to the success of a change system track gauge are reliable and able to maintain it at a low cost. In general, a lane change system should be reliable in the sense that it must not only guarantee the correct positioning of the wheels at their passage through the gauge change installation, but that this position must, in addition, be maintained during the running of the train regardless of the condition of circulation. High reliability and being able to maintain it at a low cost are the factors that will determine economic viability as this will have a consequence directly on the competitiveness of the train compared to other means of transport.

Le bogie proposé dans ce document a été développé aussi bien pour des véhicules à moteur que remorqués, et il combine un degré élevé de fiabilité avec une grande simplicité dans sa conception, qui le rendent polyvalent et avec une maintenance aisée.The bogie proposed in this document has been developed for both motor vehicles than towed, and it combines a high degree of reliability with a great simplicity in its design, which make it versatile and with maintenance easy.

Le bogie présenté a été conçu pour pouvoir effectuer le changement automatique d'écartement de voie sur des bogies automoteurs et des remorques de véhicules ferroviaires conventionnels.The bogie presented was designed to be able to make the change automatic track gauge on self-propelled bogies and trailers conventional rail vehicles.

L'emplacement du système est exclusivement restreint à l'essieu monté et aux boítes à graisse, et il permet de changer entre deux écartements de voies préétablis.The location of the system is exclusively restricted to the wheel axle and to grease boxes, and it allows you to change between two preset channel spacings.

La base du bogie est un corps d'essieu non giratoire qui agit exclusivement comme poutre de sustentation sur laquelle prend appui la transmission (pour bogies moteurs), les organes de roulement et le châssis du bogie par l'intermédiaire des caisses-supports extrêmes et la suspension primaire.The base of the bogie is a non-rotating axle body which acts exclusively as a support beam on which the transmission is supported (for motor bogies), the running gear and the chassis of the bogie by through the extreme support boxes and the primary suspension.

Les roues sont montées sur une frette, au moyen d'un système de roulements, de sorte qu'il existe entre les deux éléments la possibilité de rotation relative para rapport à l'axe commun. La frette est montée, à son tour, sur le corps d'essieu sans possibilité de pivotement sur lui-même, mais ayant la capacité de glisser, de manière à permettre le positionnement des roues sur l'essieu à la cote demandée par l'écartement de la voie. La frette incorpore les éléments qui matérialisent le verrouillage des roues en fixant leur position par l'intermédiaire des caisses-supports montées aux extrémités de l'essieu.The wheels are mounted on a hoop, by means of a system of bearings, so that there is the possibility of rotation between the two elements relative to the common axis. The hoop is mounted, in turn, on the body axle without possibility of pivoting on itself, but having the ability to slide, so as to allow the positioning of the wheels on the axle at the level requested by track gauge. The fret incorporates the elements that materialize the locking wheels by fixing their position by means of support boxes mounted on the axle ends.

La libération du verrouillage des roues est obtenue à la suite du déplacement vertical descendant du corps de l'essieu en même temps que les éléments qu'il incorpore par rapport aux caisses-supports, provoqué par le propre poids de l'essieu et combiné avec la disparition progressive (en rampe descendante) des rails d'appui des roues.The wheel lock is released after vertical downward movement of the axle body at the same time as the elements that it incorporates in relation to the support boxes, caused by the axle's own weight and combined with the gradual disappearance (down ramp) of the support rails of wheels.

Lors de l'opération de changement de l'écartement de la voie d'un essieu concret, le bogie prend appui sur cet essieu, sur les deux caisses-supports extrêmes, de sorte que l'essieu soit libéré d'une partie de la charge du véhicule qui arrive en situation de circulation. De cette manière, on obtient, en outre, que les distances relatives verticales entre l'installation de changement d'écartement et le bogie lui-même ne dépendent pas de l'état de charge du véhicule au moment de l'opération, mais exclusivement de l'état d'usure des roues.When changing the track gauge of an axle concrete, the bogie is supported on this axle, on the two extreme support boxes, so that the axle is released from a part of the load of the vehicle which arrives in situation traffic. In this way, we also obtain that the relative distances between the gauge change installation and the bogie itself does not not depend on the state of charge of the vehicle at the time of the operation, but exclusively from the state of wear of the wheels.

Dans le cas d'arbres moteurs, l'axe de sortie du réducteur (un par essieu) est composé par un arbre creux concentrique au corps de l'essieu et prenant appui sur celui-ci au moyen d'un système à roulements. Le couple moteur est transmis aux roues par l'intermédiaire de deux accouplements télescopiques capables d'absorber les déplacements transversaux nécessaires au positionnement transversal des roues. Ceci est dû au fait que chaque accouplement est constitué par deux arbres creux, qui comportent des taillages dentés complémentaires, de façon à garantir la transmission du couple, en permettant, à son tour, le déplacement axial entre les deux éléments.In the case of drive shafts, the gear unit output axis (one per axle) is composed by a hollow shaft concentric with the axle body and bearing on this by means of a bearing system. The engine torque is transmitted to the wheels by means of two telescopic couplings capable of absorbing the transverse movements necessary for the transverse positioning of the wheels. this is due to the fact that each coupling consists of two hollow shafts, which have complementary toothed cuts, so as to guarantee the transmission of the torque, in allowing, in turn, the axial displacement between the two elements.

Dans le cas d'essieux remorqués, le réducteur est remplacé par un arbre creux, qui est également monté sur le corps de l'essieu au moyen de roulements et qui sert à accoupler la rotation entre les deux roues de l'essieu.In the case of towed axles, the reduction gear is replaced by a shaft hollow, which is also mounted on the axle body by means of bearings and which is used to couple the rotation between the two wheels of the axle.

La caisse-support extrême de l'essieu est un élément rigide qui comporte, dans son corps, les logements nécessaires à l'incorporation des éléments de verrouillage, dont dispose la frette coulissante.The extreme axle support body is a rigid element which comprises, in its body, the housings necessary for incorporating the locking elements, available to the sliding hoop.

Sa connexion avec le châssis du bogie s'effectue par l'intermédiaire de la suspension primaire, matérialisée par un paquet de ressorts hélicoïdaux situés sur sa partie supérieure et chargés de transmettre les charges verticales. D'autre part, elle dispose de deux petites bielles jumelles et parallèles entre elles, qui l'unissent au châssis du bogie et aux extrémités duquel sont montées les articulations élastiques nécessaires au guidage du véhicule permettant les rigidités aussi bien longitudinale que transversale nécessaires à l'obtention de la stabilité du véhicule.Its connection with the bogie chassis is made via the primary suspension, materialized by a bundle of coil springs located on its upper part and responsible for transmitting the vertical loads. On the other hand, it has two small twin rods which are parallel to each other, which unite it to the chassis bogie and at the ends of which are mounted the necessary elastic joints guiding the vehicle allowing both longitudinal and transverse rigidities necessary to obtain vehicle stability.

Dans une variante, le bogie qui fait l'objet de l'invention dispose que chaque caisse-support se constitue en éléments de sustentation, qui retiennent entre eux l'essieu pendant la circulation et le libèrent en le laissant tomber par garvité, lorsqu'ils pivotent pour le changement d'écartement de la voie. In a variant, the bogie which is the subject of the invention provides that each support box is made up of supporting elements, which hold them together the axle during traffic and release it by dropping it by garvity, when swivel to change the gauge of the track.

Dans cette même variante, chaque caisse-support constitue deux éléments de sustentation se composant de logements, ces éléments de sustentation étant articulés sur un corps qui est accouplé coaoxialement au bout de l'essieu fixe. Ce corps se compose de deux parties entre lesquelles est fixée une extrémité en saillie de la frette coulissante, se terminant par une dent de blocage qui s'emboíte/déboíte dans les logements des éléments de sustentation, de sorte que lors de la circulation normale, la caisse support-éléments de sustentation ait un effet de tenaille sur l'essieu fixe et l'ensemble coulissant.In this same variant, each support box constitutes two elements of lift consisting of housings, these lift elements being articulated on a body which is coaoxially coupled to the end of the fixed axle. This body is consists of two parts between which is fixed a projecting end of the hoop sliding, ending with a locking tooth which fits / dislodges in the housings of the lift elements, so that during normal circulation, the support-lift body has a pincer effect on the fixed axle and the sliding assembly.

Pour mieux comprendre l'objet de la présente invention, on a représenté dans les plans une façon préférentielle de réalisation pratique, susceptible de changements accessoires qui n'en dénaturent par le fondement.To better understand the object of the present invention, there is shown in the plans a preferential way of practical realization, likely to accessory changes which do not distort the foundation.

Sur la figure 1, on présente une section longitudinale d'un essieu complet moteur en situation de circulation sur des voies ayant un écartement UIC ou international. On y a représenté les éléments essentiels dont se compose le système de changement d'écartement de la voie, et on peut apprécier comment le verrouillage des roues est matérialisé au moyen de pitons tronconiques dont dispose la frette coulissante sur laquelle sont montées les roues. Sur la même figure, deux solutions sont présentées pour la frette: la solution A avec la frette complète, sur la roue droite, et la solution B avec une frette partielle sur la roue gauche.In FIG. 1, a longitudinal section of a complete axle is presented. engine in traffic situation on tracks with a UIC gauge or international. The essential elements of which the system of change of track gauge, and we can appreciate how the locking of wheels is materialized by means of frustoconical studs available to the sliding hoop on which the wheels are mounted. In the same figure, two solutions are presented for the hoop: solution A with the complete hoop, on the right wheel, and solution B with a partial hoop on the left wheel.

La figure 2 est la même section transversale représentée sur la figure 1, mais pour une situation de circulation sur un écartement RENFE. On apprécie comment, en cette occasion, les pitons de verrouillages des roues ont changé par rapport à la situation pour un écartement UIC.Figure 2 is the same cross section shown in Figure 1, but for a traffic situation on a RENFE gauge. We appreciate how, on this occasion, the wheel lock pins have changed from the situation for a UIC gauge.

Sur la figure 3, on présente une section longitudinale d'un essieu complet remorqué en situation de circulation sur une voie ayant un écartement UIC ou international. On peut y apprécier que le réducteur a été remplacé par un arbre creux qui sert à connecter cinématiquement le mouvement de rotation des deux roues de l'essieu. De même que sur les figures 1 et 2, sur cette figure, on a également représenté les deux solutions possibles pour la frette coulissante.In FIG. 3, a longitudinal section of a complete axle is presented. towed in traffic situation on a track with a UIC gauge or international. It can be appreciated that the reduction gear has been replaced by a hollow shaft which is used to kinematically connect the rotational movement of the two wheels of the axle. As in Figures 1 and 2, this figure also shows the two possible solutions for the sliding hoop.

La figure 4 représente la même section longitudinale que la figure 3, mais pour un écartement RENFE.Figure 4 shows the same longitudinal section as Figure 3, but for RENFE spacing.

Sur les figures Sa, 5b, on a représenté les vues transversale et longitudinale de l'essieu en situation de circulation et sur le point d'entrer dans l'installation de changement d'écartement. On peut apprécier la matérialisation de la suspension primaire disposée entre la caisse-support et le châssis du bogie, et qui est composée d'un paquet de ressorts hélicoïdaux et de deux bielles jumelles. En outre, on apprécie les pitons de verrouillage dont dispose la frette et leur logement dans la caisse-support. On a représenté aussi le piton d'immobilisation du corps de l'essieu avec son logement dans la caisse-support, le pêne de sûreté avec son mécanisme d'actionnement et le réa d'appui de l'essieu, lorsque celui-ci passe par l'installation fixe de changement d'écartement.In Figures Sa, 5b, there is shown the transverse views and longitudinal of the axle in traffic situation and about to enter installation of gauge change. We can appreciate the materialization of the primary suspension arranged between the support body and the bogie chassis, and which is composed of a package of coil springs and two twin connecting rods. In addition, we appreciates the locking pins available in the hoop and their housing in the support box. The immobilization pin of the axle body with its housing in the support box, the safety bolt with its actuation mechanism and the axle bearing sheave, when this goes through the fixed changeover installation spacing.

Les figures 6a, 6b, sont les mêmes vues de l'essieu qui apparaissent sur les figures 5a, 5b, mais représentant la situation, lors de la séquence de changement d'écartement, où l'installation fixe retire le verrou de sécurité en rendant possible le repos de l'essieu par rapport à la caisse-support.Figures 6a, 6b, are the same views of the axle that appear on Figures 5a, 5b, but showing the situation during the changeover sequence spacer, where the fixed installation removes the safety lock making it possible to axle rest in relation to the support body.

Les figures 7a, 7b représentent les mêmes sections que les figures 5 et 6 mais, en cette occasion, on constate que l'essieu a été abaissé par rapport à la caisse-support, les roues étant déverrouillées et donc libres d'effectuer leur repositionnement pour le nouvel écartement de voie. De surcroít, on constate que la caisse-support supporte la charge verticale issue du véhicule, par l'intermédiaire de son appui sur le réa qui y est incorporé. Enfin, on apprécie le tronçon final du rail descendant de l'installation fixe et qui permet l'abaissement de l'essieu.Figures 7a, 7b show the same sections as Figures 5 and 6 but, on this occasion, we see that the axle has been lowered in relation to the support box, the wheels being unlocked and therefore free to reposition for the new track gauge. In addition, we see that the support box supports the vertical load from the vehicle, by pressing on the sheave incorporated into it. Finally, we appreciate the final section of the installation's descending rail fixed and which allows the lowering of the axle.

Sur la figure 8, on a représenté une vue longitudinale de l'essieu, où l'on apprécie, lors de la séquence de changement de voie, l'apparition des rails de guidage qui, moyennant leur action sur les jantes des roues, les positionnent à la cote requise par le nouvel écartement de voie.In Figure 8, there is shown a longitudinal view of the axle, where assesses, during the lane change sequence, the appearance of the guide rails which, by means of their action on the rims of the wheels, position them at the dimension required by the new track gauge.

La figure 9 représente en projection, et avec une partie sectionnée, une variante de l'objet de l'invention pour un grand écartement de voie.Figure 9 shows in projection, and with a sectioned part, a variant of the subject of the invention for a large track gauge.

La figure 10 représente en projection, et avec une partie sectionnée, la variante de la figure 9 pour un petit écartement de voie ou voie internationale UIC.Figure 10 shows in projection, and with a sectioned part, the variant of Figure 9 for a small track gauge or UIC international track.

Les figures 11 et 12 représentent une vue en plan, avec une partie sectionnée, de l'essieu pour les différents écartements de voie des figures 9 et 10.Figures 11 and 12 show a plan view, with a part sectioned, of the axle for the different track spacings of Figures 9 and 10.

Les figures 13, 14 et 15 représentent une vue latérale de l'essieu des figures 9 et 10 dans trois phases distinctes de l'opération de changement d'écartement. Sur les dessins des figures 14 et 15, on a représenté en coupe la petite bielle d'entraínement 112, qui relie le châssis du bogie (b) à l'essieu, et qui ne fait pas l'objet de ce brevet, afin de mieux voir ce qui est situé derrière elle. Sur la figure 15, on a représenté le mur de la piste de roulement en coupe, pour ne pas cacher les éléments de l'essieu qu'il est intéressant de visualiser et qui sont les éléments de sustentation - boíte-support 16b de la suspension primaire, en position ouverte, en laissant libres les dents 2a.Figures 13, 14 and 15 show a side view of the axle of the Figures 9 and 10 in three distinct phases of the spacing change operation. In the drawings of Figures 14 and 15, there is shown in section the small connecting rod 112, which connects the chassis of the bogie (b) to the axle, and which is not the subject of this patent, in order to better see what is behind it. In Figure 15, we have represented the wall of the raceway in section, so as not to hide the elements of the axle that is interesting to visualize and which are the lift elements - support box 16b of the primary suspension, in the open position, leaving the teeth free 2a.

La figure 16 représente une vue supérieure et en perspective de l'installation fixe, en supposant que dans l'explication qui est détaillée ci-dessous, le sens du passage du train se fait de haut en bas suivant la position du dessin. Dans la partie supérieure du dessin, la voie étroite 121 se rapproche de l'installation et se termine avec les rails en pente descendante 121a. Dans la partie inférieure, on voit la voie large 122, qui avait commencé avec les rails en pente ascendante 122a s'éloigner de l'installation. Entre les deux écartements de voie, on voit dessinés des rails verticaux doubles de guidage, 31 a pour l'extérieur et 31 b pour l'intérieure, qui ont pour mission de retenir et de guider les roues par leur partie inférieure, lorsque celles-ci sont libérées du poids du véhicule et de les faire passer d'une position à une autre, c'est-à-dire d'un écartement de voie à un autre, ce qu'elles peuvent faire précisément à cause de leur forme en cnala oblique ou chemin d'union entre une position et une autre des rails d'un écartement de voie et un autre écartement de voie.Figure 16 shows a top perspective view of fixed installation, assuming that in the explanation which is detailed below, the direction of passage of the train is from top to bottom depending on the position of the drawing. In the upper part of the drawing, the narrow track 121 approaches the installation and ends with downwardly sloping rails 121a. In the lower part, we see the wide track 122, which had started with the ascending rails 122a move away from the installation. Between the two track spacings, we see drawn vertical rails double guides, 31 a for the exterior and 31 b for the interior, which are responsible for retain and guide the wheels by their lower part, when these are released from the weight of the vehicle and to move them from one position to another, i.e. from one track gauge to another, which they can do precisely because of their oblique cnala shape or union path between one position and another of the rails of a track gauge and another track gauge.

Ces glissières peuvent être rigides, comme on les a représentées, ou peuvent avoir un certain amortissement ou flexibilité, pour adoucir le mouvement transversal de la roue.These slides can be rigid, as shown, or may have some cushioning or flexibility, to soften the movement transverse of the wheel.

Cette dernière opération peut avoir lieu parce que l'essieu passe par l'installation en roulant sur les réas 16r (voir figures 9, 13 et 15) sur les murets 120 où se trouvent les pistes de roulement 120b et, en outre, on réussit à centrer les essieux par rapport à l'axe de symétrie des voies, grâce aux pistes de glissement et de centrage 120a, qui frottent sur les patins 16s (Voir figures 9 et 10).This last operation can take place because the axle goes through installation by rolling on sheaves 16r (see Figures 9, 13 and 15) on low walls 120 where find the tracks 120b and, in addition, we manage to center the axles by relation to the axis of symmetry of the tracks, thanks to the sliding and centering tracks 120a, which rub on the pads 16s (See Figures 9 and 10).

Cette installation fixe est similaire dans toutes les variantes de l'invention.This fixed installation is similar in all the variants of the invention.

La figure 17 représente en projection et avec une partie sectionnée un essieu portant pssant par l'installation de changement avec un empattement des roues pour un écartement de grande voie. On peut y avoir un arbre creux 30, qui est relié à ses extrémités aux semi-accouplements 14a, afin de transmettre le mouvement d'une roue à l'autre et d'obtenir l'effet d'auto-orientation d'un essieu monté rigide, car les deux roues ont le même nombre de révolutions. De même que dans la solution avec l'arbre moteur, sur les semi-accouplements 14a, les disques de frein 8 on été montés.Figure 17 shows in projection and with a sectioned part a bearing axle weighing by the change facility with a wheel base for a track gauge. There can be a hollow shaft 30, which is connected to its ends to the semi-couplings 14a, in order to transmit the movement of a wheel to each other and get the self-steering effect of a rigid axle because both wheels have the same number of revolutions. As in the solution with the motor shaft, on the semi-couplings 14a, the brake discs 8 have been mounted.

La figure 18 est une vue éclatée, section et détail d'une moitié d'essieu, permettant d'observer la forme des pièces ainsi que le mécanisme et le fonctionnement du bogie.FIG. 18 is an exploded view, section and detail of one half of an axle, allowing to observe the shape of the parts as well as the mechanism and the functioning bogie.

Dans cette représentation, certains éléments tels que 16a et les éléments de sustentation/caisse-support 16b ont été dessinés non montés sur le corps de l'essieu 1 afin de pouvoir en voir la forme. Par exemple, on peut observer la frette coulissante 2 avec sa saillie 2a qui est la dent de fixation, et son extrémité cylindrique, où sont calés les roulements 3 et la roue 4. Cet ensemble formé de 2, 3 et 4 est ce qui peut glisser transversalement sur l'essieu 1, qui a été représenté coupé sur cette figure, afin de ne pas cacher la tête de la première pièce 2 et la dent 2a. In this representation, certain elements such as 16a and the elements lift / support box 16b were drawn unassembled on the axle body 1 so you can see the shape. For example, we can observe the sliding fret 2 with its projection 2a which is the fixing tooth, and its cylindrical end, where are wedged bearings 3 and wheel 4. This assembly formed by 2, 3 and 4 is what can slide transversely on the axle 1, which has been shown cut in this figure, so as not to hide the head of the first part 2 and the tooth 2a.

Le corps 16a et la caisse-support/élément sustentateur 16b de la droite, quand on regarde le dessin, sont sectionnés pour voir le plan incliné 16m qui serre les ressorts à anneaux 16f et qui sont également représentés démontés, pour mieux les voir aussi bien extérieurement qu'intérieurement.The body 16a and the support box / lifting element 16b from the right, when we look at the drawing, are sectioned to see the 16m inclined plane that squeezes the ring springs 16f which are also shown disassembled, for a better view both externally and internally.

L'élément sustentateur 16b de gauche est également représenté démonté et éloigné du corps 16a, afin de pouvoir voir les logements 16k dans lesquels s'encastre la frette coulissante 2 suivant l'écartement de la voie où se trouve le train.The lift element 16b on the left is also shown disassembled and away from the body 16a, in order to be able to see the housings 16k in which it fits the sliding band 2 following the spacing of the track where the train is located.

La figure 18a est un détail agrandi de la figure 18, où l'on peut observer les ressorts à anneaux 16f, qui serrent l'un contre l'autre le corps 16a et l'élément sustentateur 16b, la caisse-support sans jeux grâce au plan incliné 16m.Figure 18a is an enlarged detail of Figure 18, where we can observe the ring springs 16f, which tighten the body 16a and the element against each other lift 16b, the support box without games thanks to the inclined plane 16m.

La figure 19 est la même que la figure 18, mais avec ses éléments assemblés.Figure 19 is the same as Figure 18, but with its elements assembled.

On décrit ci-dessous un exemple de réalisation pratique, non limitative, de la présente invention.A practical, non-limiting example of embodiment of the present invention.

La description du système se fait en indiquant la situation et la fonctionnalité de chacun des éléments essentiels qui le composent. Ces éléments sont: réducteur 13, accouplement 14, disques de frein 8, flector 15, frette coulissante 2, caisse-support 16 et corps de l'essieu 1.The description of the system is made by indicating the situation and the functionality of each of its essential elements. These are: reducer 13, coupling 14, brake discs 8, flector 15, sliding hoop 2, support box 16 and axle body 1.

RÉDUCTEUR (13) (UNIQUEMENT POUR ARBRE MOTEUR) (FIGURE 1)REDUCER (13) (ONLY FOR MOTOR SHAFT) (FIGURE 1)

L'axe de sortie du réducteur 13 est formé d'un arbre creux 17, qui prend appui sur le corps de l'essieu 1 (non pivotant) grâce à un système à roulements 6.The output axis of the reducer 13 is formed by a hollow shaft 17, which takes support on the axle body 1 (not swiveling) thanks to a bearing system 6.

L'arbre creux 17 dispose d'une denture frontale (d) aux deux extrémités, grâce à laquelle le couple moteur est transmis à l'accouplement 14 et, finalement, aux roues 4.The hollow shaft 17 has a front toothing (d) at both ends, by which the engine torque is transmitted to the coupling 14 and ultimately to the wheels 4.

La carcasse du réducteur 13 prend appui sur l'arbre creux 17 de son axe de sortie, au moyen de roulements et qui est unie aux châssis du bogie (b) par une bielle à réaction (pas représentée). The casing of the reducer 13 is supported on the hollow shaft 17 of its axis outlet, by means of bearings and which is joined to the chassis of the bogie (b) by a connecting rod jet (not shown).

Le réducteur 13 est actionné au moyen d'un arbre à cardan par un moteur/transmission installés dans la caisse du véhicule (pas représenté).The reducer 13 is actuated by means of a cardan shaft by a engine / transmission installed in the vehicle body (not shown).

ARBRE CREUX 30 (UNIQUEMENT POUR ARBRE REMORQUE) (FIGURE 3)HOLLOW SHAFT 30 (ONLY FOR TRAILER SHAFT) (FIGURE 3)

C'est l'élément qui sert d'union cinématique entre les deux accouplements 14, qu sont montés sur chaque essieu 1 et qui, donc, garantit qu'ils tournent solidairement, ce qui garantit, à son tour, que les deux roues 4 de l'essieu tournent à la même vitesse, fournissant l'effet d'autoguidage qui se produit dans les essieux conventionnels.This is the element that serves as a kinematic union between the two couplings 14, which are mounted on each axle 1 and which therefore guarantees that they turn together, which in turn guarantees that the two wheels 4 of the axle rotate at the same speed, providing the autoguiding effect that occurs in conventional axles.

Physiquement, c'est un arbre creux 30 qui est monté sur la partie centrale du corps de l'essieu par l'intermédiaire des roulements 6.Physically, it is a hollow shaft 30 which is mounted on the central part of the axle body by means of the bearings 6.

ACCOUPLEMENT 14COUPLING 14

Cet élément 14, outre qu'il garantit le fait que les roues 4 de l'essieu pivotent de façon solidaire, dans le cas d'arbres moteurs, transmet le couple moteur du réducteur 13 aux roues 4. Il se compose de deux parties 14a et 14b, unies entre elles au moyen d'un couple prismatique, matérialisé par deux dentures 32 circonférentielles complémentaires (télescopiques).

  • Semi-accouplement 14a côté réducteur (pour arbre moteur) ou côté arbre creux (pour arbre remorque)
This element 14, in addition to guaranteeing that the wheels 4 of the axle pivot in an integral manner, in the case of drive shafts, transmits the driving torque of the reduction gear 13 to the wheels 4. It consists of two parts 14a and 14b, joined together by means of a prismatic couple, materialized by two complementary circumferential teeth (telescopic).
  • Semi-coupling 14a on the reduction side (for motor shaft) or hollow shaft side (for trailer shaft)

C'est un arbre creux 14a qui est monté concentriquement au corpsd de l'essieu 1 et qui est uni frontalement à l'arbre creux du réducteur 13. À ce bout, il dispose d'une denture (d) qui s'emboíte dans celle du réducteur, ce qui garantit la transmission du couple.It is a hollow shaft 14a which is mounted concentrically to the body of the axle 1 and which is united frontally with the hollow shaft of the reducer 13. At this end, it has a toothing (d) which fits into that of the reducer, which guarantees the torque transmission.

À l'extrémité opposée, il dispose, à l'intérieur, d'une denture 32 circonférentielle, qui permet le déplacement axial du semi-accouplement côté roue 14b, qui ne permet pas le pivotement relatif entre les deux éléments et, par conséquent, garantissant la transmission du couple moteur. At the opposite end, it has inside teeth 32 circumferential, which allows the axial displacement of the semi-coupling on the wheel side 14b, which does not allow the relative pivoting between the two elements and, consequently, ensuring the transmission of engine torque.

Concentriquement au semi-accouplement 14a et y étant fixé, on monte le disque de frein 8, de sorte que les deux éléments pivotent solidairement, sans que leur position varie quand on change l'écartement de la voie.

  • Semi-accouplement côté roue 14b.
Concentrically to the semi-coupling 14a and being fixed thereto, the brake disc 8 is mounted, so that the two elements pivot together, without their position varying when the gauge of the track is changed.
  • Wheel side semi-coupling 14b.

Il s'agit d'un arbre creux 14b monté lui aussi concentriquement au corps de l'essieu 1 et qui s'engrène avec la couronne du semi-accouplement côté réducteur 14a au moyen de la denture circonférentielle dont il dispose sur la surface extérieure de l'une de ses extrémités. Cette denture permet le mouvement axial entre les deux semi-accouplements, garantissant en même temps la transmission du couple moteur entre eux.It is a hollow shaft 14b also mounted concentrically to the body of axle 1 and which meshes with the crown of the semi-coupling on the reduction side 14a by means of the circumferential teeth which it has on the external surface of one of its ends. This toothing allows axial movement between the two semi-couplings, at the same time guaranteeing the transmission of the engine torque between them.

FLECTOR 15FLECTOR 15

Conceptuellement, il répond au comportement d'un accouplement classique à lames 15 et peut être monté entre l'arbre creux (17 pour les arbres moteurs, 30 pour les arbres remorques) et l'accouplement 14; ou bien entre l'accouplement 14 et la roue 4. Il s'agit d'un élément qui est capable de transmettre le couple moteur et le mouvement entre les éléments auxquels il est uni et qui, par flexion, permet de petits pivotements relatifs par rapport à des axes perpendiculaires à celui de rotation entre les deux éléments. De cette façon, de petits désalignements sont permis entre les axes sans que, pour cela, des efforts importants y étant dus soient transmis.Conceptually, it responds to the behavior of a mating conventional with blades 15 and can be mounted between the hollow shaft (17 for the driving shafts, 30 for trailer shafts) and coupling 14; or between the coupling 14 and wheel 4. This is an element which is capable of transmitting the engine torque and the movement between the elements to which it is united and which, by bending, allows small relative pivoting with respect to axes perpendicular to that of rotation between the two elements. In this way, small misalignments are allowed between the axes without that, for this, significant efforts being due to it be transmitted.

ROUE 4WHEEL 4

C'est l'élément de roulement proprement dit et il est monté sur une frette 2 avec interposition d'un système de roulements 3.It is the rolling element itself and it is mounted on a hoop 2 with interposition of a bearing system 3.

Comme on l'a indiqué précédemment, le couple moteur est transmis à la roue 4 au moyen de l'accouplement 14.As previously indicated, the engine torque is transmitted to the wheel 4 by means of coupling 14.

Les roulements 3 permettent le pivotement relatif de la roue 4 par rapport à la frette 2 (qui ne pivote pas) suivant leur axe axial commun en fixante, en outre, les deux éléments axialement, de sorte qu'ils forment un ensemble solidaire dont la seule possibilité de mouvement relatif est le pivotement mentionné auparavant.The bearings 3 allow the relative pivoting of the wheel 4 relative to to the hoop 2 (which does not pivot) along their common axial axis by fixing, in addition, the two elements axially, so that they form an integral assembly of which the only possibility of relative movement is the pivot mentioned before.

FRETTE COULISSANTE DE VERROUILLAGE 2SLIDING FREIGHT LOCK 2

C'est l'élément 2 chargé de positionner la roue 4 transversalement au corps de l'essieu 1 et il incorpore avec la caisse-support extrême 16, le système de verrouillage de celle-ci.It is element 2 responsible for positioning the wheel 4 transversely to the axle body 1 and incorporates with the extreme support box 16, the system of locking it.

Étant donné sa géométrie et en tenant compte du fait qu'il est en partie introduit dans le corps de la caisse-support extrême 16, il a uniquement la possibilité de coulisser axialement par rapport au corps de l'essieu 1, c'est pourquoi l'ajustement des deux éléments se fait sans serrage.Given its geometry and taking into account that it is partly introduced into the body of the extreme support box 16, it only has the possibility of slide axially relative to the axle body 1, this is why the adjustment of the two elements is done without tightening.

En prenant pour référence son axe axial, la frette dispose de deux parties différenciées:

  • L'extrémité 2a intérieure la plus proche de l'axe (e) longitudinal du bogie (b) fournit la surface sur laquelle est monté le système de roulements 3, qui servent de sustention à la roue 4.
  • L'extrémité 2b extérieure, extérieure au bogie, est la partie de la frette 2 qui est montée dans la caisse-support extrême 16 et comprend les éléments de verrouillage. Cette partie peut avoir deux exécutions différentes:
    • Variante A: frette complète (droite figures 1, 2, 3, 4) de façon à ce que la caisse-support 16 y prenne appui.
    • Variante B: demi-frette inférieure (gauche figures 1, 2, 3 et 4), de sorte que la caisse-support 16 prenne directement appui sur le corps de l'essieu 1.
Taking as reference its axial axis, the hoop has two differentiated parts:
  • The inner end 2a closest to the longitudinal axis (e) of the bogie (b) provides the surface on which the bearing system 3 is mounted, which serve to support the wheel 4.
  • The outer end 2b, external to the bogie, is the part of the hoop 2 which is mounted in the extreme support box 16 and includes the locking elements. This part can have two different executions:
    • Variant A: complete hoop (right figures 1, 2, 3, 4) so that the support box 16 is supported there.
    • Variant B: lower half-hoop (left in Figures 1, 2, 3 and 4), so that the support box 16 is directly supported on the axle body 1.

Chaque frette 2 comprend deux paires de pitons de verrouillage 18 disposées transversalement à la voie et orientées verticalement et dont un seul par écartement de voie intervient dans la fixation de la frette 2 et, donc, de la roue 4. À leur extrémité, les pitons 18 ont une forme tronconique afin de pouvoir les ajuster sans jeu au corps de la caisse support 16.Each hoop 2 comprises two pairs of locking pins 18 arranged transversely to the track and oriented vertically, of which only one per track spacing intervenes in the fixing of the hoop 2 and, therefore, of the wheel 4. At their end, the pegs 18 have a frustoconical shape so that they can be adjusted without play to support body 16.

L'extrémité extérieure 2b (figure 5) de la frette 2 est montée à l'intérieur de la caisse-support 16 et comprend, outre les pitons de verrouillage 18, les coulisses de guidage 19 pour l'opération de changement d'écartement et une surface plane 40 en son point le plus bas, qui sert d'appui à l'ensemble essieu sur son logement-appui 42, dans la caisse-support 16, lors du changement d'écartement de la voie.The outer end 2b (Figure 5) of the hoop 2 is mounted inside of the support box 16 and comprises, in addition to the locking pins 18, the slides of guide 19 for the spacing change operation and a flat surface 40 in sound lowest point, which serves as support for the axle assembly on its housing-support 42, in the support box 16, when changing the gauge of the track.

Les coulisses de guidage 19 sont formées de deux surfaces planes des deux côtés de la frette 2 et, suivant l'axe longitudinal du bogie, dont les surfaces antagonistes se trouvent dans le logement 43 de la caisse-support 16 pour la frette.The guide slides 19 are formed from two flat surfaces of the two sides of hoop 2 and, along the longitudinal axis of the bogie, the surfaces of which antagonists are located in the housing 43 of the support box 16 for the hoop.

À la partie inférieure 40 de la frette et de son logement-appui 42, dans la caisse-support 16, il existe un jeu (h) vertical nécessaire pour que, lorsque l'essieu monté tombe, consommant ce jeu lors du changement de voie, les pitons de verrouillage 18 sortent de leur logement dans le corps de la caisse-support 16 en laissant dégagée la frette 2 et, par conséquent, la roue 4, afin de permettre le déplacement axial vers son nouvel emplacement par rapport au corps de l'essieu 1 dans l'opération de changement de voie.At the lower part 40 of the hoop and its support housing 42, in the support box 16, there is a vertical clearance (h) necessary so that, when the axle mounted falls, consuming this game when changing lanes, the locking pins 18 come out of their housing in the body of the support box 16, leaving the hoop 2 and, consequently, the wheel 4, in order to allow the axial displacement towards its new location relative to axle body 1 in the change operation of track.

La transmission des efforts de la roue à la caisse-support se fait de la façon suivante:

  • Charge transversale (H): Elle est transmise de la roue 4 à la frette 2 à travers les roulements 3 et la frette 2 du corps de la caisse-support 16, par l'intermédiaire des pitons de verrouillage 18.
The forces are transmitted from the wheel to the support body as follows:
  • Transversal load (H): It is transmitted from the wheel 4 to the hoop 2 through the bearings 3 and the hoop 2 of the body of the support box 16, via the locking pins 18.

Variante A: Variant A :

  • Charge verticale (Q) et longitudinale (traction/frein): elle est transmise de la roue 4 à la frette 2 à travers les roulements 3 et la frette 2 au corps de la caisse-support 16, par l'intermédiaire de la surface d'appui entre les deux éléments.Vertical (Q) and longitudinal (traction / brake) load: it is transmitted from the wheel 4 to the hoop 2 through the bearings 3 and the hoop 2 to the body of the support box 16, via the bearing surface between the two elements.
Variante B: Variant B :

  • Charge verticale (Q) et longitudinale (traction/frein): elle est transmise de la roue 4 à la frette 2 à travers les roulements 3, de la frette 2 au corps de l'essieu 1, et de celui-ci au corps de la caisse-support 16, par l'intermédiaire de la surface d'appui entre les deux éléments.Vertical (Q) and longitudinal (traction / brake) load: it is transmitted from the wheel 4 to the hoop 2 through the bearings 3, from the hoop 2 to the axle body 1, and from it to the body of the support box 16, via the support surface between the two elements.
CAISSE-SUPPORT 16 EXTRÊME. SUSPENSION PRIMAIREEXTREME SUPPORT BOX 16. PRIMARY SUSPENSION

C'est l'élément qui fixe l'essieu 1 monté sur le châssis du bogie (b) par l'intermédiaire de la suspension primaire.It is the element which fixes the axle 1 mounted on the chassis of the bogie (b) by through the primary suspension.

La suspension verticale est matérialisée au moyen d'un paquet de ressorts hélicoïdaux 20 concentriques, disposés sur la caisse-support 16. La suspension transversale (guidage de l'essieu) se produit au moyen de deux petites bielles jumelles horizontales 21 aux extrémités desquelles sont montées les articulations élastiques qui offrent les rigidités longitudinale et transversale voulues. La disposition de ces bielles 21 est telle qu'elle garnatit le mouvement vertical sans rotation de la caisse-support 16, car on empêche celle-ci de pivoter par rapport à l'axe transversal de la voie.The vertical suspension is materialized by means of a package of springs concentric helical 20, arranged on the support box 16. The suspension transverse (axle guide) occurs by means of two small twin connecting rods horizontal 21 at the ends of which are mounted the elastic joints which provide the desired longitudinal and transverse stiffness. The arrangement of these connecting rods 21 is such that it garnishes the vertical movement without rotation of the support box 16, because it is prevented from pivoting relative to the transverse axis of the track.

Le corps de la caisse-support 16 dispose d'un creux 43 nécessaire pour y loger l'extrémité extérieure 2b de la frette coulissante 2 et l'extrémité du corps de l'essieu 1. En outre, il dispose de deux logements 41 dans lesquels s'introduisent les pitons de verrouillage 18 de la frette. Enfin, et comme mesure permettant d'assurer l'écart entre les roues et de garantir que le corps de l'essieu ne pivote pas, il dispose d'un troisième logement dans lequel s'introduit un piton 22 monté sur le corps de l'essieu, qui assure que des mouvements relatifs entre les deux éléments ne se produisent pas. Les logements des pitons incorporent des frettes élastiques 23, qui garantissent un appui approprié des pitons de la frette 2 et du corps de l'essieu 1.The body of the support box 16 has a hollow 43 necessary to accommodate the outer end 2b of the sliding hoop 2 and the end of the body the axle 1. In addition, it has two housings 41 into which the locking pins 18 of the hoop. Finally, and as a measure to ensure the gap between the wheels and to ensure that the axle body does not pivot, it has a third housing into which is introduced a stud 22 mounted on the axle body, which ensures that relative movements between the two elements do not occur. The pitons housing incorporates elastic frets 23, which guarantee support suitable for hoop pins 2 and axle body 1.

Extérieurement et dans sa partie inférieure, il comprend un réa 24 sur lequel il prend appui lors de l'opération de changement de voie.Externally and in its lower part, it includes a 24 sheave on which it is supported during the lane change operation.

Le corps de la caisse-support 16, en situation de circulation, prend appui soit sur la frette 2, soit sur le corps de l'essieu 1, en fonction du type de frette qui est monté (variante A ou B).The body of the support box 16, in traffic situation, is supported either on the hoop 2, or on the axle body 1, depending on the type of hoop which is mounted (variant A or B).

Entre la partie inférieure 40 de la frette 2 et le logement de celle-ci, dans la caisse-support, il existe un jeu (h) nécessaire pour que, lors de la chute verticale de l'essieu monté pendant le changement de voie, les pitons de la frette 18 et le corps de l'essieu 22 sortent de leur logement et permettent ainsi le positionnement des roues 4. Between the lower part 40 of the hoop 2 and the housing thereof, in the support box, there is a clearance (h) necessary so that, during the vertical fall of the axle mounted during the lane change, the pins of the hoop 18 and the body of the axle 22 comes out of their housing and thus allows the positioning of the wheels 4.

Comme élément de sécurité et pour éviter l'éventualité d'un déverrouillage toujours possible de la roue, à la suite de la perte de charge qu'elle supporte, les caisses-supports incorporent un pêne 25 que maintient en position un ressort 27, qui bloque le mouvement vertical de la frette 2 par rapport à la caisse-support 16. Ce pêne est retiré par l'installation fixe elle-même de changement de voie au passage du véhicule sur celle-ci, grâce à un système à levier 26, actionné par le rail sur lequel prend appui la caisse-support 16.As a security feature and to avoid the possibility of always possible unlocking of the wheel, following the pressure drop it supports, the support boxes incorporate a bolt 25 which is held in position by a spring 27, which blocks the vertical movement of the hoop 2 relative to the support box 16. This bolt is removed by the fixed lane change installation itself of the vehicle thereon, thanks to a lever system 26, actuated by the rail on which supports the support box 16.

Longitudinalement, on a disposé deux coulisses 29 (antérieure et postérieure à l'essieu), qui servent de guide vertical à l'essieu dans son mouvement par rapport à la caisse-support lors du changement de voie.Longitudinally, we arranged two slides 29 (anterior and posterior to the axle), which serve as a vertical guide for the axle in its movement by report to the support body when changing lanes.

CORPS DE L'ESSIEU 1AXLE BODY 1

Il agit comme une poutre de sustentation 1 de la transmission et de l'ensemble de roulement du bogie. C'est un élément qui ne pivote pas et dont la position est garantie par les caisses-support 16.It acts as a support beam 1 of the transmission and the bogie bearing assembly. It is an element which does not rotate and whose position is guaranteed by the support boxes 16.

Il se déplace uniquement lors du changement de voie (en même temps que tous les éléments qu'il comprend) en se déplaçant verticalement vers le bas par rapport au corps de la caisse-support 16.It only moves when changing lanes (at the same time as all the elements that it includes) by moving vertically down relative to to the body of the support box 16.

Il comprend deux pitons 22 (un à chaque bout) dans sa partie supérieure, qui, logés dans le corps des caisses-supports, garantissent son immobilité et l'écartement entre les roues 4.It includes two pitons 22 (one at each end) in its upper part, which, housed in the body of the support boxes, guarantee its immobility and spacing between the wheels 4.

INSTALLATION FIXEFIXED INSTALLATION

L'installation de changement de voie consiste en (figures 5, 6 et 7):The lane change installation consists of (Figures 5, 6 and 7):

Deux pistes de roulement ou rails additionnels 29, sur lesquelles roulent les réas 24, qui sont incorporés dans les caisses-supports extrêmes.Two additional tracks or tracks 29, on which roll sheaves 24, which are incorporated in the extreme support boxes.

Un tronçon de voie descendant 28 avec l'écartement actuel. Cette voie disparaít au moment où l'essieu prend appui de façon intégrale, et par l'intermédiaire des boítes à graisse, sur les pistes de roulement 29. À ce moment-là, les roues 4 et leurs frettes 2 sont déverrouillées du fait de l'abaissement de l'essieu 1. A section of descending track 28 with the current gauge. This way disappears when the axle is fully supported, and through the grease boxes, on the raceways 29. At this time, the wheels 4 and their frets 2 are unlocked due to the lowering of axle 1.

Deux rails de guidage 32 (figure 8) qui sont chargés de porter chaque roue à sa position transversale pour le nouvel écartement de voie, une fois qu'elle a été déverrouillée.Two guide rails 32 (Figure 8) which are responsible for carrying each wheel at its transverse position for the new track gauge, once it has been unlocked.

Un tronçon de voie ascendant avec le nouvel écartement de voie et qui permet le verrouillage des roues en forçant la montée de l'essieu jusqu'à sa position de circulation, ce qu fait que, simultanément, les réas des caisses-supports perdent contact avec les pistes de roulement (opération inverse à celle de l'abaissement).An ascending section of track with the new track gauge which allows the wheels to be locked by forcing the axle to rise to its position of circulation, which causes the sheaves of the support boxes to lose contact simultaneously with runways (reverse operation to lowering).

PROCÉDURE DE CHANGEMENT D'ÉCARTEMENTGAP CHANGE PROCEDURE

L'unité passe à travers l'installation de changement d'écartement à faible vitesse, sous l'impulsion de son propre équipement de traction.The unit passes through the low gauge change facility speed, driven by its own traction equipment.

Le rail de roulement 28 des roues descend progressivement (figure 6), de sorte qu'il arrive un moment où les caisses-supports 16 extrêmes de l'axe correspondant prennent appui, au moyen du réa 24 qu'elles incorporent sur un rail additionnel 29, disposé à cet effet. Simultanément, et grâce à l'interaction de l'extrémité 50 du levier 26 avec le rail additionnel 29, le pêne de sûreté 25 est retiré pour permettre la chute de l'essieu et de la frette 2 par rapport à la caisse-support 16.The running track 28 of the wheels descends gradually (FIG. 6), from so that there comes a time when the end support boxes 16 of the corresponding axis are supported by means of the sheave 24 which they incorporate on an additional rail 29, arranged for this purpose. Simultaneously, and thanks to the interaction of the end 50 of the lever 26 with the additional rail 29, the safety bolt 25 is removed to allow the fall of the axle and the hoop 2 relative to the support box 16.

Au moment où l'appui a lieu sur les caisses-supports 16, l'essieu 1 monté commence à s'abaisser jusqu'à qu'il occupe le creux (h) existant entre la caisse-support 16 et la frette coulissante 2, l'essieu étant alors complètement déchargé, moment où disparaít le rail de voie 28 (figure 7). Le mouvement vertical de l'essieu est guidé par rapport à la caisse-support au moyen de deux coulisses 19 qui comprennent la frette coulissante 2 et les surfaces conjuguées de la caisse-support 16.When the support takes place on the support boxes 16, the axle 1 mounted begins to lower until it occupies the hollow (h) between the support box 16 and the sliding hoop 2, the axle then being completely unloaded, when disappears the track rail 28 (Figure 7). The vertical movement of the axle is guided by relative to the support box by means of two slides 19 which include the hoop sliding 2 and the mating surfaces of the support box 16.

Au moment où l'essieu s'abaisse, les pitons d'ancrage 18 et 22 dont dispose la freete coulissante 2 et le corsp de l'essieu 1 sortent respectivement de leur logement dans le corps de la caisse-support 16, les roues étant alors déverrouillées et ayant donc une liberté de mouvement transversal par rapport au corps de l'essieu 1 (figure 7). When the axle lowers, the anchor bolts 18 and 22 of which has the sliding freete 2 and the axle corsp 1 respectively out of their housing in the body of the support box 16, the wheels then being unlocked and thus having a freedom of transverse movement relative to the body of the axle 1 (figure 7).

Au moyen des guides-cames 31, qui agissent sur les côtés de la jante des roues 4 (figure 8), chaque roue 4 est amenée à la position correspondant à l'écartement de voie voulu.By means of the cam guides 31, which act on the sides of the rim of the wheels 4 (figure 8), each wheel 4 is brought to the position corresponding to the spacing desired track.

Une fois les roues 4 positionnées, le rail apparaít avec le nouvel écartement de voie en rampe ascendante, sur lequel elles commencent à rouler, ce qui oblige l'essieu à monter verticalement, de sorte à produire, de façon progressive, le verrouillage des roues au moyen de l'introduction des pitons 18 correspondants de la frette 2 dans leur logement de la caisse-support 16, en même temps que le pêne 25 revient à sa position d'origine, poussé par le ressort de récupération 27. Simultanément, les roues commencent à supporter la charge verticale jusqu'à ce que, finalement, les caisses-supports 16 perdent contact avec le rail auxiliaire et que toute la charge soit supportée par la nouvelle voie, par l'intermédiaire des roues de l'essieu 4.Once the wheels 4 positioned, the rail appears with the new track ascending ramp, on which they begin to roll, which forces the axle to mount vertically, so as to gradually produce the locking of the wheels by means of the introduction of the corresponding pins 18 of the hoop 2 in their housing of the support box 16, at the same time as the bolt 25 returns to its original position, pushed by the recovery spring 27. Simultaneously, the wheels begin to support the vertical load until, finally, the support boxes 16 lose contact with the auxiliary rail and all the load is supported by the new track, via the wheels of the axle 4.

On décrit ci-dessous la variante des figures 9, 10 et suivantes:The variant of FIGS. 9, 10 and following is described below:

Sur le corps d'essieu 1 qui ne pivote pas (voir figures 9 et 10), des frettes coulissantes 2 creuses sont montées, qui, elles non plus, ne pivotent pas, mais qui peuvent glisser transversalement sur l'essieu 1. Elles ne peuvent coulisser que lorsque le véhicule et, par conséquent, chaque essieu, passe par l'installation fixe de changement d'écartement de voie et que celle-ci débloque les frettes coulissantes 2.On the axle body 1 which does not pivot (see Figures 9 and 10), hoops sliding 2 hollow are mounted, which also do not rotate, but which can slide transversely on axle 1. They can only slide when the vehicle and therefore each axle goes through the fixed changeover facility track gauge and that it releases the sliding frets 2.

Sur la frette coulissante 2, on a installé les roulements 3, sur lesquels les roues 4 puevent rouler. Ces roues 4 sont accouplées, au moyen d'un flector 15 à un semi-accouplement strié 14b, qui s'engrène sur un autre semi-accouplement 14a uni à un arbre creux 17, par lequel elles reçoivent le couple de rotoation et, donc, le mouvement que transmet un réducteur 13 qui tourne en étant appuyé avec les roulements 6 sur l'essieu fixe 1. Sur le semi-accouplement du côté du réducteur 14a, on a monté les disques de frein 8.On the sliding hoop 2, the bearings 3 were installed, on which the 4 wheels can roll. These wheels 4 are coupled, by means of a flector 15 to a semi-coupling striated 14b, which meshes on another semi-coupling 14a joined to a tree hollow 17, by which they receive the rotational torque and, therefore, the movement that transmits a reduction gear 13 which turns while being supported with the bearings 6 on the axle fixed 1. On the semi-coupling on the side of the reducer 14a, the discs of brake 8.

Dans le cas d'un matériel remorqué (voir figure 17), le réducteur est remplacé par un arbre creux 30 qui accouple cinématiquement les deux roues de l'essieu, se comportant comme un essieu monté, en vue d'une auto-orientation. L'arbre creux 30 utilisé sur l'essieu portant est l'équivalent de l'arbre creux 17 de l'arbre moteur.In the case of towed equipment (see figure 17), the reduction gear is replaced by a hollow shaft 30 which kinematically couples the two wheels of the axle, behaving like a wheel axle for self-orientation. The hollow tree 30 used on the bearing axle is the equivalent of the hollow shaft 17 of the drive shaft.

Les extrémités du corps de l'essieu fixe 1 prennent appui sur les caisses-supports. La caisse-support est constituée fondamentalement par deux éléments sustentateurs 16b articulés à un corps 16a au moyen de boulons 111. Grâce aux articulations, la caisse-support peut s'ouvrir pour permettre à l'essieu de pouvoir s'abaisser et de se déverrouiller de sa position initiale. À chaque exrémité du corps de l'essieu fixe 1, il y a un corps 16a (voir figures 9, 10, 11, 12 et 17), formé de deux parties 16h et 16j. Ces deux parties sont celles qui permettent de fixer l'extrémité en saillie de la frette coulissante 2. Cette extrémité comporte une zone très saillante, où se trouvent les dents pour le blocage 2a.The ends of the body of the fixed axle 1 bear on the support boxes. The support box basically consists of two elements lifters 16b articulated to a body 16a by means of bolts 111. Thanks to the joints, the support box can be opened to allow the axle to be able lower and unlock from its original position. At each end of the body of the fixed axle 1, there is a body 16a (see figures 9, 10, 11, 12 and 17), formed of two parts 16h and 16d. These two parts are those which allow the projecting end of the sliding hoop 2. This end has a very protruding area, where the teeth for locking 2a.

Lorsque le véhicule passe par l'installation de changement d'écartement, l'essieu tombe par gravité, la frette coulissante 2 est libérée et commence à glisser sur le corps de l'essieu 1, grâce à l'action des rails de guidage 31. La course transversale de la frette coulissante 2 est limitée, parce que la saillie des dents 2a ne peut se déplacer qu'entre les butées 16c et 16d du corps 16a, (figures 9 et 10). Ces butées admettront toujours une certaine course un peu plus longue que celle qui est nécessaire et qui n'est autre que le différentiel entre les deux écartements de voie. Cette tolérance en trop permet d'assurer que la fixation exacte est bien réalisée par les dents 2a, lorsqu'elles s'encastrent dans les logements 16k des caisses-supports 16b des ressorts de la suspension primaire.When the vehicle goes through the gauge change installation, the axle falls by gravity, the sliding hoop 2 is released and begins to slide on the axle body 1, thanks to the action of the guide rails 31. The transverse stroke of the sliding hoop 2 is limited, because the projection of the teeth 2a cannot move that between the stops 16c and 16d of the body 16a, (Figures 9 and 10). These stops will admit always a certain stroke a little longer than that which is necessary and which is not other than the differential between the two track spacings. This excess tolerance ensures that the exact fixation is achieved by the teeth 2a, when they fit into the housings 16k of the support boxes 16b of the springs of the primary suspension.

Le poids que transmettent les ressorts 27 de la suspension primaire a 16b font que ceux-ci se serrent sur les dents 2a en permettant un verrouillage sans aucun jeu entre les éléments de sustentation 16b et la frette coulissante 2. Ce verrouillage sans jeux est possible grâce à la forme trapézoïdale des dents. Les jeux possibles se produisant du fait de jeux dus au boulon 11 sont également éliminés grâce à la poussée qu'effectuent les ressorts à anneau 16f (voir figures 11, 12 et 18a) à l'union du corps 16a sur la caisse-support/élément sustentateur 16b. D'autre part, la configuration articulée de la caisse-support 16b permet à l'essieu 1, lorsque celle-ci prend appui sur ses réas 16r, de se décharger de la charge verticale et de tomber par rapport à lui et au châssis du bogie. De cette manière, il est possible d'effectuer le déverrouillage de l'essieu de sa position initiale.The weight transmitted by the springs 27 of the primary suspension to 16b make these tighten on teeth 2a allowing locking without any play between the lift elements 16b and the sliding hoop 2. This locking without play is possible thanks to the trapezoidal shape of the teeth. Possible games occurring from made of games due to bolt 11 are also eliminated thanks to the thrust that effect the ring springs 16f (see Figures 11, 12 and 18a) at the union of the body 16a on the support box / element lift 16b. On the other hand, the articulated configuration of the support box 16b allows the axle 1, when the latter is supported on its sheaves 16r, to be unload vertical load and fall relative to it and the bogie chassis. Of this way it is possible to unlock the axle from its position initial.

D'autre part, l'union ferme entre les frettes coulissantes 2 et le corps 16a est garantie par les éléments sustentateurs 16b qui, supportant le poids du véhicule, les prennent les deux ensembles en étau avec tout ce poids et sans jeu entre les deux.On the other hand, the firm union between the sliding frets 2 and the body 16a is guaranteed by the lifting elements 16b which, supporting the weight of the vehicle, take the two sets in a vice with all this weight and without play between the two.

Pour éviter que, du fait d'un mouvement quelconque non voulu dans la circulation de la caisse-support / éléments sustentateurs 16b, ils ne perdent momentanément la poussée du poids du véhicule, de sorte que la sécurité de cette union puisse être mise en danger et, par conséquent, qu'il y ait un glissement non prévu des frettes coulissantes 2, qui en ferait varier la position de façon non souhaitable, les éléments sustentateurs 16b comportent des cliquets 16n articulés, sur lesquels les ressorts 16p exercent une pression, afin qu'ils ne sortent pas des tétons 16g du corps 16a (voir figure 18). De cette façon, tant que ces cliquets ne sont pas soulevés par l'installation fixe, l'union entre les frettes coulissantes 2, le corps 16a et la caisse-support/éléments sustentateurs 16b est garantie.To avoid that, due to any unwanted movement in the circulation of the support box / lifting elements 16b, they do not lose momentarily pushing the weight of the vehicle so that the safety of this union may be endangered and, therefore, there may be an unexpected slide in the sliding frets 2, which would cause the position to be undesirably varied, the lift elements 16b comprise articulated pawls 16n, on which the springs 16p exert a pressure, so that they do not come out of the nipples 16g of the body 16a (see figure 18). This way, as long as these pawls are not lifted by the fixed installation, the union between the sliding hoops 2, the body 16a and the support box / elements lift 16b is guaranteed.

Comme on peut le voir sur le dessin de la figure 16, l'installation de changement d'écartement de la voie consiste en:As can be seen in the drawing in Figure 16, the installation of change of track gauge consists of:

Deux pistes de roulement latérales 120, où passera l'essieu en roulant sur les réas 16r des éléments sustentateurs (voir figures 9, 10, 13, 14 et 15), sur la surface de roulement 120b, et les essieux coulissant sur des patins centreurs 16s sur la surface de centrage 120a. Ces bandes de roulement et de glissement sont, toutes les deux, effilées aussi bien à leur début qu'à leur terminaison, afin d'éviter, dans les deux sens de passage, c'est-à-dire lorsqu'on passe de la voie espagnole à l'internationale ou à l'inverse, des interférences possibles au début de l'opération. Ces effilements servent également à guider et à centrer l'essieu à l'entrée de l'installation. Two lateral running tracks 120, where the axle will pass while rolling on the sheaves 16r of the lift elements (see FIGS. 9, 10, 13, 14 and 15), on the surface of bearing 120b, and the axles sliding on centering pads 16s on the surface of centering 120a. These treads and slip are both tapered both at their beginning and at their termination, in order to avoid, in both directions of passage, that is to say when going from the Spanish way to the international or to conversely, possible interference at the start of the operation. These tapers serve also to guide and center the axle at the entrance to the installation.

Avant et après ces pistes latérales, il y a les voies ayant les différents écartements, l'une à chaque entrée de l'installation. Au même point où prend fin l'effilement de la piste de roulement, commencent les voies à descendre en pente. De cette manière, l'essieu, au moment de rouler sur la pente, perd de la hauteur jusqu'à ce que les réas des cliquets 16n (voir figure 13) entrent en contact avec les pistes de roulement latérales 120, commencent à s'ouvrir et à libérer les tétons 16g, comme on peut le voir sur la figure 6. Ensuite, ils entrent en contact avec les réas 16r qui finiront par se charger du poids du véhicule et libèreront les roues de cette charge (voir figure 15).Before and after these side tracks, there are the tracks having the different spacings, one at each entrance to the installation. At the same point where it ends tapering of the runway, the tracks begin to slope. Of this way, the axle, when rolling on the slope, loses height until that the sheaves of the pawls 16n (see figure 13) come into contact with the tracks of side bearings 120, begin to open and release the 16g nipples, as we can see it in figure 6. Then they come into contact with the 16r sheaves which will end by taking on the weight of the vehicle and freeing the wheels from this load (see figure 15).

Une fois que le poids que le poids du véhicule est supporté intégralement par les éléments sustentateurs / caisse-support 16b et du fait de la géométrie même de la suspension primaire, ces éléments sustentateurs 16b s'ouvrent, leurs logements 16k se dégagent des dents 2a de la frette coulissante 2 et le corps 16a s'abaisse en accompagnant l'essieu.Once the weight the vehicle weight is fully supported by the lift elements / support box 16b and due to the very geometry of the primary suspension, these lift elements 16b open, their housings 16k disengage teeth 2a from the sliding hoop 2 and the body 16a lowers in accompanying the axle.

Il est évident que cela arrive parce que l'essieu 1, les frettes coulissantes 2 tombent de leur propre poids avec la roue 4, le réducteur 13 et le corps 16a, étant aidés, de surcroít, par la rotation qui a lieu du fait de la poussée des ressorts 27 de la suspension primaire.Obviously this happens because the axle 1, the sliding frets 2 fall of their own weight with the wheel 4, the reduction gear 13 and the body 16a, being helped, in addition, by the rotation which takes place due to the thrust of the springs 27 of the suspension primary.

L'installation fixe de changement est complétée par des rails de guidage des roues 31, l'un extérieur 3 la et l'autre intérieur 31 b, qui servent à guider et à déplacer la roue d'un écartement à l'autre, et à garantir que la roue arrive bien à sa position correcte.The fixed change installation is completed by guide rails wheels 31, one outside 3 a and the other inside 31 b, which serve to guide and move the wheel from one gauge to another, and to ensure that the wheel arrives at its position correct.

Il est logique que l'installation soit conçue en tenant compte des usures toujours possibles des roues et des rails, que peuvent subir le bogie et ses éléments pendant le fonctionnement normal.It is logical that the installation should be designed taking wear into account wheels and rails, which the bogie and its components can always undergo during normal operation.

Sur les figures 13, 14 et 15, on a représenté, en trois phases, les moments les plus représentatifs de la situation concernant l'entrée d'un essieu, au passage par l'installation de changement d'écartement de voie, pour que le changement puisse avoir lieu.In FIGS. 13, 14 and 15, the moments are shown in three phases the most representative of the situation concerning the entry of an axle, passing through the track gauge change facility, so that the change can have location.

Sur le dessin de la figure 13, on a représenté une vue latérale d'un essieu d'un bogie doté du système de changmenet d'écartement de voie qui, circulant sur une voie, quelle qu'en soit l'écartement, se dispose à entrer dans l'installation de changement. Sur le dessin, on a également représenté le muret 120 sustentateur des pistes de roulement 120b et de glissement qui demeurent cachées. On peut également observer le rail 121 sur lequel circulent la roue et la partie inclinée 12 la qui commence à descendre.In the drawing of Figure 13, there is shown a side view of an axle a bogie fitted with the track gauge changmenet system which, running on a track, whatever the gauge, gets ready to enter the installation of change. In the drawing, the low wall 120 is also shown. 120b rolling and sliding tracks which remain hidden. We can also observe the rail 121 on which the wheel circulates and the inclined part 12 la which begins to go down.

Sur la figure 14, on peut voir comment, la roue ayant commencé à descendre sur la pente du rail 121a, les réas des cliquets 16n sont entrés en contact avec la piste de roulement 120b avant que les réas de roulement 16r qui le feront plus tard. Pendant cet intervalle de temps, les cliquets 16n se sont complètement ouverts en libérant les tétons 16g. À partir de cet instant, la caisse-support /les éléments sustentateurs 16b peuvent se séparer l'un de l'autre, à la suite de l'action des ressorts de la suspension primaire, à mesure que les roues continuent de descendre avec le corps de l'essieu sur le rail 12 la (voir figure 15).In figure 14, we can see how, the wheel having started to descend on the slope of the rail 121a, the sheaves of the pawls 16n have come into contact with the rolling track 120b before the rolling sheaves 16r which will do so later. During this time interval, the pawls 16n have fully opened in releasing the nipples 16g. From this moment, the support box / elements lifters 16b can separate from each other, following the action of the springs the primary suspension, as the wheels continue to descend with the body of the axle on the rail 12 la (see FIG. 15).

On peut observer, en outre, sur la même figure 15, comment la roue, à un certain moment, a perdu contact avec le rail. Le poids du véhicule repose à présent sur les réas 16r qui, en le recevant, ont déséquilibré les éléments sustentateurs 16b de leur position normale. Ceci a lieu ainsi du fait de la disposition géométrique de ces éléments: le point d'application de la charge verticale que transmet le ressort sur le rail (le réa 16r) est décentré par rapport à l'axe de pivotement de l'élément sustentateur 16b, ce qui fait que celui-ci pivotera par rapport au boulon 111, en faisant que le corps de l'essieu 1, les frettes coulissantes 2, la roue 4, le réducteur 13 et le corps 16 s'abaissent.We can also observe, in the same figure 15, how the wheel, at a moment, lost contact with the rail. The weight of the vehicle is now based on the sheaves 16r which, when received, have unbalanced the lifting elements 16b of their normal position. This takes place as a result of the geometric arrangement of these elements: the point of application of the vertical load transmitted by the spring on the rail (sheave 16r) is off-center with respect to the pivot axis of the lifting element 16b, which makes that it will pivot relative to bolt 111, making the axle body 1, the sliding hoops 2, the wheel 4, the reduction gear 13 and the body 16 are lowered.

La caisse-support / éléments sustentateurs 16b pivotera jusqu'à ce que sa saillie 16s bute sur le corps 16a, ce qui donne lieu à une séparation suffisante entre les dents 2a de la frette coulissante et les logements 16k, pour se dégager et permettre le glissement de la frette coulissante 2 sur l'essieu 1. Le déplacement transversal entre les frettes coulissantes et l'essieu s'effectue jusqu'à ce que la dent 2a se place en face de son nouveau logement. Tout ceci est rendu possible par les rails de guidage 31a et 31b de l'installation fixe, qui obligent l'ensemble formé par la roue 4 montée sur les roulements 3 dans la frette coulissante 2 à changer d'écartement.The support box / lifting elements 16b will pivot until its projection 16s abuts on body 16a, which gives rise to a sufficient separation between the teeth 2a of the sliding hoop and the housings 16k, to disengage and allow the sliding of the sliding hoop 2 on the axle 1. The transverse movement between the sliding frets and the axle is carried out until the tooth 2a is placed opposite its new housing. All this is made possible by the guide rails 31a and 31b of the fixed installation, which requires the assembly formed by the wheel 4 mounted on the bearings 3 in the sliding hoop 2 to change spacing.

Cette nouvelle position devra être fixée de nouveau avec toutes les sécurités, comme auparavant, le véhicule continuant à passer dans l'installation et réalisant donc le processus inverse de celui décrit précédemment. En premier lieu, les roues commenceront à rouler sur le rail ayant le nouvel écartement qui est maintenant en pente montante.This new position will have to be fixed again with all the safeties, as before, the vehicle continuing to pass through the installation and therefore carrying out the reverse process to that described above. First, wheels will start to roll on the rail with the new gauge which is now in rising slope.

Allant de cette manière, les roues, les éléments sustentateurs 16b, qui reprennent du poids, se ferment peu à peu en pivotant sur les boulons 111 jusqu'à ce qu'ils prennent en étau les dents 2a de la frette coulissante, au moyen de leurs logements 16k dans la nouvelle position.Going in this way, the wheels, the lifting elements 16b, which gain weight, gradually close by pivoting on bolts 111 until they grip the teeth 2a of the sliding hoop, by means of their housings 16k in the new position.

Enfin, les réas des cliquets 16n cesseront peu à peu de rouler sur la piste de roulement 120b et reverrouilleront l'ensemble en entrant dans les tétons 16g. Ceci arrive, car l'essieu continue à monter sur le plan incliné de la voie jusqu'à ce qu'il atteigne la voie plane.Finally, the sheaves of the 16n pawls will gradually stop rolling on the track bearing 120b and relock the assembly when entering the nipples 16g. This happens, because the axle continues to climb on the incline of the track until it reaches the level track.
