Description

La présente invention concerne une zone d'intercirculation comportant deux parois d'extrémité de deux voitures successives d'un véhicule ferroviaire.The present invention relates to an intercirculation zone comprising two end walls of two successive cars of a railway vehicle.

Une telle zone d'intercirculation est connue du document FR 2786452 A1 . Les véhicules ferroviaires pour le transport de passagers sont couramment formés d'une succession de voitures communiquant les une avec les autres. A cet effet, un passage d'intercirculation est aménagé entre les extrémités adjacentes de deux voitures successives. Lors de passages en courbe, le passage d'intercirculation doit pouvoir se déformer. Ainsi, il est connu d'utiliser un soufflet dont les extrémités sont liées aux voitures successives pour délimiter le passage d'intercirculation. Les passagers peuvent alors circuler au travers du soufflet qui forme un couloir étanche.Such an intercirculation zone is known from the document FR 2786452 A1 . Passenger rail vehicles are commonly formed from a succession of cars communicating with each other. For this purpose, a gangway is arranged between the adjacent ends of two successive cars. When crossing in curves, the gangway must be able to deform. Thus, it is known to use a bellows whose ends are connected to successive cars to delimit the gangway. The passengers can then circulate through the bellows forming a sealed corridor.

Dans les trains à grande vitesse, le soufflet est constitué d'un seul profil fermé, en caoutchouc, de faible épaisseur, celle-ci étant de l'ordre de 1,5 mm. Ce soufflet n'est pas totalement satisfaisant d'un point de vue acoustique.In high-speed trains, the bellows consists of a single closed profile, of rubber, of small thickness, this being of the order of 1.5 mm. This bellows is not totally satisfactory from an acoustic point of view.

Par ailleurs, il existe des soufflets à double peau, les peaux étant chacune constituées d'une toile revêtue de caoutchouc. Les deux peaux forment des ondulations successives et présentent en elles-mêmes une forme de soufflet. Les deux peaux sont maintenues entre elles par des liaisons disposées au niveau de tous les sommets des ondulations en regard des deux peaux.In addition, there are double skin bellows, the skins each being made of a cloth coated with rubber. The two skins form successive undulations and present in themselves a form of bellows. The two skins are held together by connections arranged at all the vertices of the undulations opposite the two skins.

Cette solution est également imparfaite d'un point de vue acoustique.This solution is also imperfect from an acoustic point of view.

L'invention a pour but de proposer un soufflet d'intercirculation qui présente de bonnes propriétés d'isolation sonore, tout en garantissant une largeur d'intercirculation importante et en préserver la capacité de compression et déformation en débattement de l'intercirculation.The invention aims to provide a gusset intercirculation which has good sound insulation properties, while ensuring a large intercirculation width and preserve the compression capacity and deformation in deflection of the gangway.

A cet effet, l'invention a pour objet de fournir une zone d'intercirculation selon la revendication 1. Suivant des modes particuliers de réalisation, le soufflet d'intercirculation comporte l'une ou plusieurs des caractéristiques suivantes :

  • les ondulations rentrantes et sortantes des peaux extérieure et intérieure présentent des sommets disposés en vis-à-vis dans un même plan transversal au soufflet,
  • les deux peaux sont reliées l'une à l'autre au plus au niveau des sommets en regard des ondulations rentrantes et sortantes,
  • la proportion d'ondulations en regard des peaux extérieure et intérieure reliées entre elles est compris entre 30% et 60% du nombre total d'ondulations en regard,
  • les peaux extérieure et intérieure sont liées l'une à l'autre par des charnières s'étendant suivant l'essentiel de la longueur des ondulations des deux peaux,
  • les charnières comportent un premier ensemble de charnons liés à la peau extérieure et un second ensemble de charnons liés à la peau intérieure, les charnons étant intercalés et traversés par une tige autour de laquelle ils sont chacun articulés,
  • les peaux extérieure et intérieure présentent suivant chacun de leur bord, un rebord de fixation faisant saillie respectivement vers l'extérieur et l'intérieur du soufflet,
  • les rebords de fixation sont rapportés par surmoulage au bord des peaux extérieure et intérieure,
  • les peaux extérieure et intérieure ont une même épaisseur,
  • l'épaisseur des peaux extérieure et intérieure est comprise entre 3 et 7 mm,
  • les peaux extérieure et intérieure présentent, suivant leur bords périphériques opposés, des plats d'assemblage suivant lesquels les deux peaux sont comprimées l'une contre l'autre,
  • les ondulations des peaux extérieure et intérieure ont une hauteur comprise entre 20 et 35 mm, et
  • les ondulations des peaux extérieure et intérieure ont, au repos, une longueur comprise entre 20 et 30 mm.
To this end, the object of the invention is to provide a gangway zone according to claim 1. According to particular embodiments, the gangway bellows comprises one or more of the following features:
  • the re-entrant and outgoing corrugations of the outer and inner skins have vertices arranged facing each other in the same plane transverse to the bellows,
  • the two skins are connected to each other at the most at the level of the peaks facing the incoming and outgoing corrugations,
  • the proportion of corrugations with respect to the outer and inner skins connected to each other is between 30% and 60% of the total number of corrugations facing each other,
  • the outer and inner skins are connected to one another by hinges extending substantially along the length of the undulations of the two skins,
  • the hinges comprise a first set of knuckles linked to the outer skin and a second set of knuckles linked to the inner skin, the knuckles being inserted and traversed by a rod around which they are each articulated,
  • the outer and inner skins have, each along their edge, a fixing flange protruding respectively outwardly and inside the bellows,
  • the fixing flanges are reported by overmoulding at the edge of the outer and inner skins,
  • the outer and inner skins have the same thickness,
  • the thickness of the outer and inner skins is between 3 and 7 mm,
  • the outer and inner skins have, according to their opposite peripheral edges, assembly plates in which the two skins are compressed against each other,
  • the undulations of the outer and inner skins have a height of between 20 and 35 mm, and
  • the undulations of the outer and inner skins have, at rest, a length of between 20 and 30 mm.

L'invention a, en outre, pour objet une zone d'intercirculation comportant deux parois d'extrémité de deux voitures successives d'un véhicule ferroviaire, chacune délimitant une ouverture de passage et un soufflet d'intercirculation tel que défini ci-dessus, relié aux deux parois entre les deux ouvertures de passage.The invention further relates to an intercirculation zone comprising two end walls of two successive cars of a railway vehicle, each defining a passage opening and a gangway bellows as defined above, connected to the two walls between the two openings.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins, sur lesquels :

  • la figure 1 est une vue en perspective de la zone d'intercirculation entre deux voitures montrant le soufflet d'intercirculation selon l'invention ;
  • la figure 2 est une vue en coupe longitudinale de la zone d'intercirculation entre deux voitures montrant le soufflet d'intercirculation selon l'invention ;
  • la figure 3 est une vue partielle en coupe à plus grande échelle du soufflet d'intercirculation au repos, c'est-à-dire sans sollicitation axiale ;
  • la figure 4 est une vue en perspective de deux brides de retenue des extrémités du soufflet d'intercirculation ;
  • la figure 5 est une vue identique à celle de la figure 3, le soufflet d'intercirculation étant dans son état comprimé ; et
  • la figure 6 est une vue identique à celle de la figure 3, le soufflet d'intercirculation étant dans son état étiré.
The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the drawings, in which:
  • the figure 1 is a perspective view of the intercirculation zone between two cars showing the gangway bellows according to the invention;
  • the figure 2 is a longitudinal sectional view of the intercirculation zone between two cars showing the gangway bellows according to the invention;
  • the figure 3 is a partial view in section on a larger scale of the gaiter intercirculation rest, that is to say without axial stress;
  • the figure 4 is a perspective view of two retaining flanges of the ends of the gangway bellows;
  • the figure 5 is a view identical to that of the figure 3 the gangway bellows being in its compressed state; and
  • the figure 6 is a view identical to that of the figure 3 , the gangway bellows being in its stretched state.

La zone d'intercirculation 10 représentée sur la figure 1 est celle d'un train constitué de voitures automotrices grande vitesse assemblées les unes aux autres. Une telle zone d'intercirculation existe entre chaque paire de voitures successives. Elle comporte ainsi, deux parois 12, 14 prévues aux extrémités des deux voitures. Deux ouvertures 16, 18 sont délimitées au travers des parois 12, 14 en regard pour la circulation des passagers. Ces ouvertures sont de forme générale rectangulaire, la longueur étant disposée verticalement.The intercirculation zone 10 represented on the figure 1 is that of a train consisting of high speed motor cars assembled to each other. Such an intercirculation zone exists between each pair of successive cars. It thus comprises two walls 12, 14 provided at the ends of the two cars. Two openings 16, 18 are delimited through the walls 12, 14 opposite for the movement of passengers. These openings are of generally rectangular shape, the length being arranged vertically.

Un soufflet 20 selon l'invention est disposé entre les deux ouvertures. Il est lié à chacune de ses extrémités aux parois d'extrémité 12, 14 et forme avec celles-ci la zone d'intercirculation 10.A bellows 20 according to the invention is disposed between the two openings. It is connected at each of its ends to the end walls 12, 14 and forms with them the interconnection zone 10.

Le soufflet forme un contour fermé et délimite ainsi un conduit clos permettant la circulation des passagers. En section, il présente globalement une forme sensiblement identique à celle des ouvertures 16, 18 dans le prolongement desquelles il est installé.The bellows form a closed contour and thus delimits a closed conduit allowing the movement of passengers. In section, it generally has a shape substantially identical to that of the openings 16, 18 in the extension of which it is installed.

Le soufflet comprend, comme illustré sur les figures 2 et 3, une peau extérieure 22 et une peau intérieure 24, toutes deux ondulées et liées l'une à l'autres par des liens périphériques espacés longitudinalement les un des autres. Les deux peaux délimitent entre elles un espace d'isolation phonique 25 essentiellement clos.The bellows includes, as illustrated on the figures 2 and 3 , an outer skin 22 and an inner skin 24, both corrugated and bonded to each other by peripheral links spaced longitudinally from one another. The two skins delimit between them an essentially closed sound insulation space 25.

Les peaux extérieure 22 et intérieure 24 présentent à leurs deux extrémités des rebords périphériques 26, 28 respectivement sortant et rentrant par rapport au soufflet lui-même. Les rebords sont disposés dans un même plan et opposés l'un à l'autre. Ils sont chacun formés à l'extrémité d'un bord périphérique plat 30, 32 prévu à chaque extrémité des deux peaux. Ces bords périphériques plats 30, 32 sont maintenus accolés l'un à l'autre et forment ensemble une âme cylindrique 34 du soufflet s'étendant dans la partie médiane de son épaisseur suivant un plan médian P. Ainsi, les deux rebords 26, 28 forment ensemble un bourrelet de liaison 36 faisant saillie radialement de part et d'autre de l'âme 34.The outer skins 22 and inner 24 have at their two ends peripheral rims 26, 28 respectively outward and re-entrant relative to the bellows itself. The edges are arranged in the same plane and opposed to each other. They are each formed at the end of a flat peripheral edge 30, 32 provided at each end of the two skins. These flat peripheral edges 30, 32 are held together adjacent to each other and together form a cylindrical core 34 of the bellows extending in the middle portion of its thickness along a median plane P. Thus, the two flanges 26, 28 together form a connecting bead 36 projecting radially on either side of the core 34.

De préférence, les rebords de fixation 26, 28 sont rapportés par surmoulage au bord des peaux extérieure 22 et intérieure 24.Preferably, the fixing flanges 26, 28 are attached by overmolding to the edge of the outer skin 22 and inner skin 24.

Pour la liaison du soufflet, les bourrelets de liaison 36 sont chacun enserrés entre deux brides de liaison. L'une notée 38 est solidaire de chaque paroi d'extrémité 12, 14 et l'autre notée 40A, 40B est rapportée sur la paroi d'extrémité associée.For the connection of the bellows, the connecting beads 36 are each sandwiched between two connecting flanges. One denoted 38 is integral with each end wall 12, 14 and the other denoted 40A, 40B is attached to the associated end wall.

Comme illustré sur la figure 2, les brides 38 délimitent un canal périphérique 42 de réception du rebord 26 dont l'ouverture est tournée vers l'intérieur.As illustrated on the figure 2 the flanges 38 delimit a peripheral channel 42 for receiving the rim 26 whose opening is turned inwards.

Les brides rapportées 40A, 40B, représentées seules sur la figure 4, comportent un canal périphérique 44 dont l'ouverture est tournée vers l'extérieur. Chaque canal 44 est propre à recevoir un rebord 28.The reported flanges 40A, 40B, represented alone on the figure 4 , comprise a peripheral channel 44 whose opening is turned towards the outside. Each channel 44 is adapted to receive a flange 28.

Le canal 44 est solidaire d'une couronne 46 de fixation périphérique adjacente qui borde le canal 44 suivant toute sa longueur. La couronne de fixation 46 est percée de trous régulièrement répartis suivant sa longueur au travers desquels sont engagées des vis d'assemblage 48 vissées dans les brides 38.The channel 44 is secured to an adjacent peripheral fixing ring 46 which borders the channel 44 along its entire length. The fixing ring 46 is pierced with holes regularly distributed along its length through which are engaged assembly screws 48 screwed into the flanges 38.

Alors que la bride 40A forme un contour fermé, la bride 40B est interrompue suivant un coté inférieur pour permettre le passage d'un seuil 50, visible sur la figure 1, qui assure la retenue du soufflet dans cette zone. A cet effet, le seuil délimité un canal de réception du rebord 28.While the flange 40A forms a closed contour, the flange 40B is interrupted along a lower side to allow the passage of a threshold 50, visible on the figure 1 , which ensures the retention of the bellows in this area. For this purpose, the threshold defines a reception channel of the flange 28.

Comme illustré sur la figure 3, les peaux extérieure 22 et intérieure 24 présentent chacune dans leur partie médiane sur l'essentiel de leur longueur entre les bords 32, 34 des plages ondulées 52, 54, formées d'ondulations successives 56, 58. Ces ondulations 56, 58 sont déportées à l'opposé l'une de l'autre de part et d'autre du plan médian P de l'épaisseur du soufflet. Elles s'étendent ainsi globalement vers l'extérieur et vers l'intérieur par rapport aux rebords 26, 28.As illustrated on the figure 3 , the outer skins 22 and inner 24 each have in their middle part the most of their length between the edges 32, 34 of the corrugated areas 52, 54, formed of successive corrugations 56, 58. These corrugations 56, 58 are deported opposite each other on both sides of the median plane P of the thickness of the bellows. They thus extend generally outwardly and inwardly with respect to the flanges 26, 28.

Les deux peaux 22, 24 ont un même nombre d'ondulations 56, 58 et sont en section symétriques l'une de l'autre par rapport au plan médian P.The two skins 22, 24 have the same number of corrugations 56, 58 and are in section symmetrical to each other with respect to the median plane P.

Les ondulations des plages ondulées 52, 54 sont périodiques et sont sensiblement de forme sinusoïdale. Le nombre d'ondulations est compris entre 8 et 15 et est par exemple égal à 11.The corrugations of the corrugated areas 52, 54 are periodic and are substantially sinusoidal in shape. The number of corrugations is between 8 and 15 and is for example equal to 11.

Ainsi, les ondulations rentrantes 56 et sortantes 58 des plages ondulées des peaux extérieure 22 et intérieure 24 respectivement présentent des sommets 60, 62 disposés en vis-à-vis dans un même plan transversal au soufflet.Thus, the re-entrant 56 and outgoing corrugations 58 of the corrugated areas of the outer skins 22 and inner skins 24 respectively have vertices 60, 62 arranged facing each other in the same plane transverse to the bellows.

Les plages ondulées 52, 54 des deux peaux sont reliées l'une à l'autre au plus au niveau de certains sommets 60, 62 en regard des ondulations rentrantes et sortantes. Ainsi, les peaux extérieure 22 et intérieure 24 sont liées entre elles au niveau seulement de certains sommets 60, 62 d'ondulations en regard, les autres ondulations des deux peaux restant séparées et libres l'une de l'autre.The corrugated beaches 52, 54 of the two skins are connected to one another at most at certain vertices 60, 62 facing the incoming and outgoing corrugations. Thus, the outer skins 22 and inner skins 24 are interconnected at only certain vertices 60, 62 of undulations opposite, the other undulations of the two skins remaining separate and free from each other.

Ainsi, par exemple, un sommet 60 sur deux environ est lié au sommet 62 de l'autre peau en regard suivant la longueur du soufflet.Thus, for example, a vertex 60 of about two is linked to the top 62 of the other skin facing the length of the bellows.

De préférence, la proportion d'ondulations en regard reliées entre elles est compris entre 30% et 60% et est de préférence sensiblement égale à 40% des ondulations en regard, ainsi de 40 à 70% des ondulations en regard ne sont pas liées.Preferably, the proportion of facing corrugations connected to each other is between 30% and 60% and is preferably substantially equal to 40% of the opposing corrugations, so 40 to 70% of the opposing undulations are not related.

Les peaux extérieure 22 et intérieure 24 sont liées l'une à l'autre par des charnières 64 s'étendant suivant l'essentiel de la longueur des sommets des ondulations en regard.The outer skins 22 and inner 24 are connected to one another by hinges 64 extending substantially along the length of the peaks of the undulating faces.

A cet effet, les charnières comportent un premier ensemble de charnons 66 liés à la peau extérieure 22 et un second ensemble de charnons 68 liés à la peau intérieure 24. Les charnons 66, 68 sont intercalés et articulés autour d'une tige commune 70 s'étendant suivant toute la longueur de la charnière et engagée au travers des charnons successifs 66, 68.For this purpose, the hinges comprise a first set of knuckles 66 connected to the outer skin 22 and a second set of knuckles 68 connected to the inner skin 24. The knuckles 66, 68 are interposed and articulated around a common shank 70 extending along the entire length of the hinge and engaged through the successive knuckles 66, 68.

Les peaux extérieure 22 et intérieure 24 ont une même épaisseur. De préférence, l'épaisseur de plages ondulées 52, 54 des peaux extérieure 22 et intérieure 24 est comprise entre 3 et 7 mm. Elle est de préférence sensiblement égale à 4,5 mm. Les deux peaux sont autoportantes et sont formées d'un caoutchouc adapté. Les peaux ne comportent que du caoutchouc et sont dépourvues de tissus, ou de toute autre matrice, de support du caoutchouc.The outer skins 22 and inner 24 have the same thickness. Preferably, the thickness of corrugated areas 52, 54 of outer skin 22 and inner skin 24 is between 3 and 7 mm. It is preferably substantially equal to 4.5 mm. Both skins are self-supporting and are made of a suitable rubber. The skins contain only rubber and are devoid of fabrics, or any other matrix, of rubber support.

Les ondulations ont une hauteur comprise entre 20 et 35 mm et de préférence sensiblement égale à 27 mm. Les ondulations ont, au repos, une longueur comprise entre 20 et 30 mm.The corrugations have a height of between 20 and 35 mm and preferably substantially equal to 27 mm. The undulations have, at rest, a length of between 20 and 30 mm.

Ainsi, les zones ondulées 52, 54 du soufflet présentent au repos une longueur de sensiblement 258 mm, celle-ci étant réduite à 190 mm lorsque le soufflet est dans son état comprimé comme illustré sur la figure 5 et atteignant 410 mm, lorsque le soufflet est dans son état étiré comme illustré sur la figure 6.Thus, the corrugated zones 52, 54 of the bellows have a rest length of substantially 258 mm, the latter being reduced to 190 mm when the bellows is in its compressed state as shown in FIG. figure 5 and reaching 410 mm, when the bellows is in its stretched state as illustrated on the figure 6 .

Du fait de sa double peau, le soufflet peut être gonflé au montage pour atteindre sa dimension de pose et faciliter le montage. Le passage en moule pour former le soufflet définitif à partir du profil caoutchouc extrudé formant les plages ondulées 52, 54 permet d'intégrer une opération d'ajout de matière différente à la périphérie du soufflet qui forme le bourrelet de liaison 36, de dureté et de forme adaptée pour améliorer l'étanchéité du montage sur les extrémités des voitures.Because of its double skin, the bellows can be inflated during assembly to reach its installation dimension and facilitate assembly. The passage in mold to form the definitive bellows from the extruded rubber profile forming the corrugated areas 52, 54 makes it possible to integrate a different material addition operation at the periphery of the bellows which forms the connecting bead 36, of hardness and shape adapted to improve the tightness of the assembly on the ends of the cars.

Le nombre de liaisons entre les deux peaux étant réduits, leur effet néfaste au point de vue de l'isolation acoustique est réduit tout en permettant une bonne cohésion du soufflet pour les passages en courbes et la résistance aux sollicitations dues aux ondes de pression.The number of connections between the two skins being reduced, their adverse effect from the point of view of sound insulation is reduced while allowing a good cohesion of the bellows for the curves and the resistance to stresses due to pressure waves.
