Description

La présente invention se rapporte à une unité de transport ferroviaire combiné rail/route.The present invention relates to a rail / road combined rail transport unit.

Les wagons relatifs au transport combiné rail/route à structure porteuse pivotante comportent deux plates-formes d'extrémité supportées par des bogies ferroviaires sur lesquelles est montée par des liaisons d'assemblage dissociable la structure ferroviaire porteuse de la charge routière.The rail / road combined transport wagons with pivoting support structure comprise two end platforms supported by railway bogies on which the load bearing railway structure is mounted by means of assembly links.

Le maintien de la position de ces plates-formes d'extrémité s'avère primordial pour assurer la coïncidence, l'enclenchement et la fermeture des liaisons d'assemblage dissociable entre la structure porteuse et les plates-formes d'extrémité et de recréer ainsi l'intégrité du wagon après les phases de chargement et de déchargement.Maintaining the position of these end platforms is essential to ensure the coincidence, engagement and closure of the dissociable assembly links between the supporting structure and the end platforms and to recreate as well. the integrity of the wagon after the loading and unloading phases.

Pour remédier à cet inconvénient limitant la course de pivotement et entraînant une fabrication plus complexe au niveau des liaisons entre la structure porteuse et les plates-formes d'extrémité, deux alternatives s'offraient aux constructeurs.To remedy this disadvantage limiting the pivoting stroke and resulting in a more complex manufacture at the level of the connections between the carrier structure and the end platforms, two alternatives were offered to the manufacturers.

La première concerne des moyens au sol, c'est-à-dire intégrés dans la voie ferroviaire qui ont pour but d'immobiliser les plates-formes d'extrémité en les retenant en place par une liaison temporaire avec la voie. Cette solution présente un coût qui ne permet pas de la proposer dans un système compétitif.The first relates to the ground means, that is to say, integrated in the railway which are intended to immobilize the end platforms by holding them in place by a temporary link with the track. This solution has a cost that does not allow to propose it in a competitive system.

La seconde consiste à intégrer les plates-formes d'extrémité dans une structure porteuse appelée double plancher ou un moyen équivalent par laquelle passent tous les efforts représentés par la charge et la traction. Au dessus de cette structure porteuse est monté pivotant autour d'un pivot un autre plancher porté par exemple par des moyens de roulement en contact avec la face supérieure de la structure porteuse qui supporte ainsi toute la charge. Cette structure porteuse assure une liaison mécanique permanente avec les plates-formes d'extrémité et garantit le maintien en position relative de celles-ci lors des mouvements de dissociation du wagon liés aux opérations de chargement/déchargement.The second is to integrate the platforms end in a supporting structure called double floor or equivalent means through which spend all the efforts represented by the load and traction. Above this support structure is pivotally mounted around a pivot another floor carried for example by rolling means in contact with the upper face of the carrier structure which thus supports the entire load. This bearing structure provides a permanent mechanical connection with the end platforms and ensures the relative position of the latter during car dissociation movements related to the loading / unloading operations.

Outre le renchérissement notable de l'ensemble du wagon, la structure porteuse représente une masse et une épaisseur conséquentes prises sur les caractéristiques générales et dimensionnelles du wagon.In addition to the significant increase in the overall weight of the wagon, the load-bearing structure represents a substantial mass and thickness taken from the general and dimensional characteristics of the wagon.

En particulier, l'épaisseur de cette structure porteuse diminue la hauteur utile de chargement qui risque de ne plus s'inscrire dans le gabarit ferroviaire.In particular, the thickness of this carrier structure decreases the useful loading height which may no longer be included in the rail gauge.

Par ailleurs, cette structure porteuse assurant le passage des canalisations, des conduits et des câbles permettant le transfert des fluides d'énergie et de commande et l'alimentation électrique des structures et équipements, ne peut être supprimée facilement.Furthermore, this carrier structure ensuring the passage of pipes, conduits and cables for the transfer of energy and control fluids and the power supply of structures and equipment can not be easily removed.

L'invention a pour but d'assurer la retenue en position relative initiale des plates-formes d'extrémité pendant les phases de chargement/déchargement tout en permettant l'utilisation de la totalité du gabarit ferroviaire et le passage des câbles et des conduits.The invention aims to ensure the retention in initial relative position of the end platforms during the loading / unloading phases while allowing the use of the entire rail gauge and the passage of cables and ducts.

A cet effet, l'invention propose une unité ferroviaire ayant les caractéristiques de la revendication 1.For this purpose, the invention proposes a rail unit having the features of claim 1.

Le dispositif de retenue et de liaison selon l'invention se compose d'une liaison mécanique de longueur constante sous la forme d'un élément longitudinal de liaison 1 reliant entre elles à un niveau bas deux plates-formes d'extrémité 2 et 3 supportées chacune par au moins un bogie ferroviaire 4 ou 5. Cet élément longitudinal de liaison 1 est fixé ou articulé par chacune de ses extrémités à une plate-forme correspondante d'extrémité 2 ou 3 à un niveau bas.The retaining and connecting device according to the invention consists of a mechanical link of constant length in the form of a longitudinal connecting element 1 interconnecting at a low level two end platforms 2 and 3 supported. each by at least one railway bogie 4 or 5. This longitudinal connecting element 1 is fixed or articulated by each of its ends to a corresponding end platform 2 or 3 at a low level.

Cet élément longitudinal de liaison 1 n'a pas d'autre but principal que de relier mécaniquement les deux plates-formes d'extrémité entre elles afin de les retenir dans leur position initiale pendant les phases de chargement et de déchargement.This longitudinal connecting element 1 has no other main purpose than mechanically connecting the two end platforms together in order to retain them in their initial position during the loading and unloading phases.

Il s'applique principalement à un wagon de transport combiné rail/route constitué de deux plates-formes d'extrémité 2 et 3 reliées à une structure ferroviaire porteuse 6 dissociable et pivotante qui transmet tous les efforts de traction et les différents efforts en jeu lors du roulage d'une plate-forme d'extrémité à l'autre.It applies mainly to a wagon of combined rail / road transport consisting of two end platforms 2 and 3 connected to a separable and pivotable carrier structure 6 which transmits all the traction forces and the various forces involved when driving a platform of end to another.

Ainsi, l'élément longitudinal de liaison 1 peut être réalisé avec une faible épaisseur pour ne pas pénaliser les dimensions utiles de chargement par rapport au gabarit ferroviaire.Thus, the longitudinal connecting element 1 can be made with a small thickness so as not to penalize the useful dimensions of loading relative to the rail gauge.

En effet, il n'est soumis qu'à son propre poids et aux éventuelles forces d'éloignement et de rapprochement des plates-formes lorsque la structure porteuse est dissociée.Indeed, it is subject only to its own weight and the possible forces of distance and approximation of the platforms when the carrier structure is dissociated.

Cette structure porteuse pivotante présente un plancher porteur 7 à fond 8 plat ou autrement conformé.This pivoting carrier structure has a floor 7 flat bottom 8 flat or otherwise shaped.

Dans une première réalisation, non représentée, cet élément longitudinal de liaison 1 reste en saillie à l'extérieur du plancher 7.In a first embodiment, not shown, this longitudinal connecting element 1 remains projecting outside the floor 7.

Selon un autre mode de réalisation que l'on développera ci-après, il vient se loger dans un logement longitudinal en retrait 9 en forme de tunnel 10 équipant ou formé dans le plancher 7 de la structure ferroviaire porteuse 6.According to another embodiment that will be developed hereinafter, it is housed in a recessed longitudinal recess 9 in the form of a tunnel 10 equipping or formed in the floor 7 of the carrying railway structure 6.

En raison de sa longueur et de la faible épaisseur de sa section, cet élément longitudinal de liaison 1 a tendance à fléchir vers le bas dans sa partie centrale. Cette flexion provoquant un dépassement vers le bas pouvant mettre l'ensemble hors gabarit, il convient de rappeler cet élément vers le haut dans sa partie centrale 11, par exemple par une fixation simple ou une suspension en partie centrale inférieure de la structure ferroviaire porteuse 6. De façon préférentielle, pour gagner sur le gabarit ferroviaire, on prévoit d'encastrer l'élément longitudinal de liaison 1 dans un logement en retrait 9 en forme de tunnel central longitudinal 10 formé dans le plancher 7 de la structure ferroviaire porteuse 6. Ce tunnel 10 permet aussi de faire passer les conduits de fluide sous pression et les câbles de liaison électrique d'une plate-forme d'extrémité 2 ou 3 à l'autre.Due to its length and the small thickness of its section, this longitudinal connecting element 1 tends to bend downwards in its central part. This bending causing a downward overshoot can put the assembly out of jig, it should be recalled this element upwards in its central portion 11, for example by a simple attachment or a suspension in the lower central portion of the carrying railway structure 6 Preferably, to gain on the rail gauge, it is intended to embed the longitudinal connecting element 1 in a recessed housing 9 in the form of longitudinal central tunnel 10 formed in the floor 7 of the carrying railway structure 6. This tunnel 10 also makes it possible to pass the pressurized fluid conduits and the electrical connection cables of an end platform 2 or 3 to the other.

Cet élément longitudinal de liaison 1 remplit sa fonction principale de retenue en position relative des plates-formes d'extrémité 2 et 3 dans leur position relative initiale lors des manoeuvres de chargement/déchargement pour assurer la rapidité et la commodité de l'assemblage entre les plates-formes d'extrémité et les extrémités de la structure ferroviaire porteuse 6 dans tous les cas de position du centre de pivotement de celle-ci.This longitudinal connecting element 1 fulfills its main function of retaining relative position of the end platforms 2 and 3 in their initial relative position during the loading / unloading maneuvers to ensure the speed and convenience of the assembly between the end platforms and the ends of the carrying railway structure 6 in all cases of position of the pivot center thereof.

En effet, l'invention vise non seulement les structures ferroviaires 6 pivotant autour de leur centre mais aussi celles pivotant au niveau d'une de leurs extrémités ou en un endroit quelconque.Indeed, the invention aims not only railway structures 6 pivoting around their center but also those pivoting at one of their ends or at any location.

L'élément longitudinal de liaison 1 remplit une deuxième fonction technique lorsque l'axe de pivotement est central. Il s'agit de supporter un centre de pivotement 12.The longitudinal connecting element 1 fulfills a second technical function when the pivot axis is central. This is to support a pivot center 12.

De ce fait, pour le type de variante à logement en tunnel, la partie centrale 11 de cet élément de liaison 1, dont un exemple est représenté sur les figures de 6 à 10, devient plus complexe.Therefore, for the type of tunnel housing variant, the central portion 11 of this connecting element 1, an example is shown in Figures 6 to 10, becomes more complex.

Sur cet exemple, la partie centrale 11 remplit trois fonctions simultanément, à savoir celle d'assurer la fixation de l'élément longitudinal de liaison 1 à la structure ferroviaire porteuse 6, celle de supporter le centre de pivotement 12 autour duquel pivote la structure ferroviaire porteuse 6 et finalement celle en coopération avec des moyens associés de réaliser le désengagement de l'élément longitudinal de liaison 1 de son logement 9 prévu en retrait sous la forme du tunnel 10 prévu dans le plancher 7 de la structure ferroviaire porteuse.In this example, the central portion 11 performs three functions simultaneously, namely that of ensuring the attachment of the longitudinal connecting element 1 to the carrying railway structure 6, that of supporting the pivot center 12 around which rotates the railway structure carrier 6 and finally that in cooperation with associated means to achieve the disengagement of the longitudinal connecting member 1 of its recessed housing 9 in the form of the tunnel 10 provided in the floor 7 of the carrying railway structure.

Il s'agit d'un ensemble complexe de liaison que l'on peut qualifier aussi de dégagement-pivotement 13.It is a complex set of links that can also be described as pivoting clearance 13.

Plus précisément et en prenant comme exemple le mode de réalisation représenté sur les figures 6 et 7, la partie centrale 11 de l'élément longitudinal de liaison 1 est suspendue sur la face supérieure du tunnel 10 de plancher de la structure ferroviaire porteuse 6. A cet effet, une lame métallique 14 de suspension bombée à effet de ressort est montée immobilisée en butée à chacune de ses extrémités par trois points fixes le long desquels elle peut bouger par ses bords longitudinaux et le long d'une fente longitudinale centrale de guidage 15 et 16 existant de part et d'autre d'une zone centrale médiane transversale.More precisely, and taking as an example the embodiment shown in FIGS. 6 and 7, the central portion 11 of the longitudinal connecting element 1 is suspended on the upper face of the floor tunnel 10 of the carrying railway structure 6. this effect, a metal leaf spring suspension curved 14 is mounted immobilized abutting at each of its ends by three fixed points along which it can move by its longitudinal edges and along a longitudinal central guide slot 15 and 16 existing on both sides of a central median transverse zone.

Le bombé de cette lame laisse libre un espace 17 de débattement situé entre la face supérieure du logement en tunnel 10 et la face en regard de ladite lame métallique de suspension 14.The crown of this blade leaves free a clearance space 17 located between the upper face of the tunnel housing 10 and the opposite face of said metal suspension plate 14.

Cet espace 17 de débattement est occupé par un ensemble moteur de dégagement 18 par exemple à énergie pneumatique comprenant une paire de soufflets pneumatiques 19 et 20 comme représenté.This clearance space 17 is occupied by a clearance motor assembly 18, for example a pneumatic energy comprising a pair of pneumatic bellows 19 and 20 as shown.

Cette lame métallique de suspension 14 porte à travers l'ensemble moteur 18 de dégagement un centre de pivotement 21 par exemple sous la forme d'un bloc-pivot 22 sur lequel est fixé par sa partie centrale l'élément longitudinal de liaison 1 par exemple par des vis telles que 23 formant ainsi un ensemble complexe de liaison entre le plancher et l'élément de liaison 1.This metal suspension plate 14 carries through the motor assembly 18 a clearance center pivoting 21 for example in the form of a pivot block 22 on which is fixed by its central portion longitudinal connecting element 1 for example by screws such as 23 thus forming a complex assembly of connection between the floor and the connecting element 1.

Comme on le verra ci-après, il ne s'exerce sur ce centre de pivotement aucune force sensible en raison du maintien de la structure ferroviaire porteuse par les plates-formes d'extrémité 2 et 3 au travers de ces bras pendant toutes les phases de manoeuvre et pendant le transport. Ainsi, la résistance mécanique du centre de pivotement et des éléments voisins n'a pas besoin d'être importante.As will be seen below, no appreciable force is exerted on this center of pivoting because of the maintenance of the carrying railway structure by the end platforms 2 and 3 through these arms during all the phases. maneuvering and during transport. Thus, the mechanical strength of the pivot center and neighboring elements does not need to be important.

En ce qui concerne l'élément longitudinal de liaison 1, sa structure est mince et diverses formes de section sont possibles, depuis des formes à section rectangulaire telles que représenté sur la figure 2, jusqu'à des formes minces nervurées ou pliées dont quelques exemples sont représentés sur les figures 11 à 13.With regard to the longitudinal connecting element 1, its structure is thin and various sectional shapes are possible, from rectangular section shapes as shown in FIG. 2, to thin ribbed or folded shapes, some examples of which are are shown in Figures 11 to 13.

La forme particulière montrée par la figure 11 sera préférée. Il s'agit d'une forme générale plate dont les bords longitudinaux sont conformés en tubes creux 24 et 25, par exemple de section circulaire, servant de canalisation pour les fluides sous pression soit directement, soit comme espace de protection et de passage pour des conduits simples ou des câbles électriques ou autres.The particular shape shown in Figure 11 will be preferred. It is a generally flat shape whose longitudinal edges are shaped into hollow tubes 24 and 25, for example of circular section, serving as a channel for pressurized fluids either directly or as a protection and passage space for single ducts or electrical cables or others.

Ces liaisons fluidiques ou électriques, d'énergie ou de commande trouvent ainsi un passage longitudinal approprié non gênant et parfaitement intégré.These fluidic or electrical, energy or control connections thus find a suitable longitudinal passage that is not annoying and perfectly integrated.

De plus, ces bords longitudinaux apportent un supplément de rigidité mécanique à l'ensemble, permettant ainsi de diminuer encore l'épaisseur de section de l'élément longitudinal de liaison 1.In addition, these longitudinal edges provide additional mechanical rigidity to the assembly, thereby further reducing the section thickness of the longitudinal connecting element 1.

D'autres conformations à pliages longitudinaux 26 et 27 ou à courbure de renforcement concave 28, sont également possibles. Un exemple de chacune de ces variantes est représenté sur les figures 12 et 13.Other conformations with longitudinal folds 26 and 27 or concave reinforcing curvature 28 are also possible. An example of each of these variants is shown in Figures 12 and 13.

De façon générale, l'élément longitudinal de liaison 1 est de préférence sensiblement plat et mince.In general, the longitudinal connecting element 1 is preferably substantially flat and thin.

Les extrémités de l'élément de liaison 1 peuvent affecter une forme en deux branches divergentes en deux branches divergentes par exemple en Y pour le passage de moyens de levage et d'entraînement en pivotement montés sur la voie. L'ouverture des branches de chaque extrémité de l'élément de liaison 1 peut varier jusqu'à une ouverture maximale selon laquelle les extrémités viennent porter sur les extrémités adjacentes inférieures des flancs des plates-formes d'extrémité 2 et 3 en vue de coopérer avec des organes de la liaison dissociable ou de fixation prévus à ce niveau.The ends of the connecting element 1 may affect a shape in two divergent branches in two divergent branches for example Y for the passage of lifting means and pivot drive mounted on the track. The opening of the branches each end of the connecting element 1 may vary to a maximum opening in which the ends come to bear on the lower adjacent ends of the sides of the end platforms 2 and 3 in order to cooperate with organs of the dissociable bond or attachment provided at this level.

De plus, il est prévu d'alléger l'élément de liaison 1 par des perforations ou des ouvertures dans son plan comme représenté.In addition, it is intended to lighten the connecting element 1 by perforations or openings in its plane as shown.

Bien d'autres formes de réalisation sont possibles. Elles entrent toutes dans le domaine de protection de l'invention dans la mesure où elles remplissent la fonction générale de retenir en position les plates-formes d'extrémité lors des mouvements de la structure ferroviaire porteuse 6 au cours des phases de chargement et de déchargement.Many other embodiments are possible. They all fall within the scope of protection of the invention insofar as they fulfill the general function of holding the end platforms in position during the movements of the carrying railway structure 6 during the loading and unloading phases. .

Le fonctionnement d'ensemble de l'invention est le suivant. Lorsque la structure ferroviaire porteuse est amenée à pivoter pour les phases de chargement et de déchargement, avant tout mouvement de pivotement, on actionne l'ensemble moteur 18 de dégagement à soufflets qui, en se gonflant et en prenant appui sur la voûte du logement 9 en tunnel 10, forcent la lame bombée 14 à se bomber davantage et donc à s'éloigner de la voûte du tunnel. Celle-ci, en se bombant davantage, parcourt une course d'écartement qui suffit à dégager ou à extraire l'élément longitudinal de liaison de son logement 9 en tunnel 10. La structure ferroviaire porteuse 6 peut alors pivoter librement autour de son centre de pivotement matérialisé ici par le bloc-pivot 22 monté sur la partie centrale 11 de l'élément longitudinal de liaison 1.The overall operation of the invention is as follows. When the carrier rail structure is pivoted for the loading and unloading phases, before any pivoting movement, actuates the bellows release engine assembly 18 which, by swelling and bearing on the roof of the housing 9 in tunnel 10, force the curved blade 14 to bulge further and thus to move away from the tunnel vault. The latter, by becoming more bulging, travels a distance race which is sufficient to release or extract the longitudinal connecting element of its housing 9 in tunnel 10. The carrying railway structure 6 can then rotate freely around its center. pivoting materialized here by the pivot block 22 mounted on the central portion 11 of the longitudinal connecting element 1.

Lors du retour de la structure ferroviaire porteuse 6 et après assemblage de celle-ci avec les plates-formes d'extrémité restées en position grâce à l'élément longitudinal de liaison 1, la succession inverse de mouvements se produit. Les soufflets de l'ensemble moteur de dégagement 18 se dégonflent et l'élément longitudinal de liaison 1 entre dans son logement 9 en forme de tunnel 10 sous l'effet de la force élastique de rappel de la lame métallique de suspension.During the return of the carrying railway structure 6 and after assembly thereof with the end platforms remained in position thanks to the longitudinal connecting element 1, the succession inverse movement occurs. The bellows of the release motor assembly 18 deflate and the longitudinal connecting element 1 enters its housing 9 in the form of a tunnel 10 under the effect of the elastic force of return of the metal suspension plate.
