Description

La présente invention concerne un véhicule ferroviaire du type comprenant au moins deux voitures adjacentes, comprenant chacune une caisse de voiture, chaque voiture comprenant un plancher inférieur et un plancher supérieur, disposés l'un au-dessus de l'autre de sorte à définir un niveau inférieur et un niveau supérieur, lesdites caisses étant supportées par un bogie commun et étant articulées l'une à l'autre par un dispositif d'articulation fixé aux deux caisses de sorte à former une liaison articulée entre les deux caisses.The present invention relates to a railway vehicle of the type comprising at least two adjacent cars, each comprising a car body, each car comprising a lower floor and an upper floor, arranged one above the other so as to define a lower level and an upper level, said bodies being supported by a common bogie and being articulated to one another by an articulation device fixed to the two bodies so as to form an articulated connection between the two bodies.

L'invention s'applique plus particulièrement aux véhicules ferroviaires à deux étages destinés à des trajets entre plusieurs villes, du type trains à grande vitesse, trains interrégionaux et autres.The invention applies more particularly to double-decker railway vehicles intended for journeys between several cities, of the high-speed train type, interregional trains and the like.

Les documents EP-0 616 935 A1 , DE 295 12 446 U1 et EP-0 642 964 A1 décrivent des véhicules ferroviaires comprenant deux étages.The documents EP-0 616 935 A1 , DE 295 12 446 U1 and EP-0 642 964 A1 describe railway vehicles comprising two floors.

Dans ce type de véhicules ferroviaires, l'interconnexion entre les voitures successives se fait généralement sur un seul niveau, c'est-à-dire que les passagers doivent monter au niveau supérieur ou descendre au niveau inférieur pour passer d'une voiture à la suivante, ce qui complique la circulation dans le véhicule ferroviaire et pose problème pour les personnes à mobilité réduite.In this type of rail vehicle, the interconnection between successive cars is usually on a single level, i.e. passengers have to board the upper level or descend to the lower level to go from one car to the next. following, which complicates movement in the rail vehicle and poses a problem for people with reduced mobility.

Il a été proposé, par exemple dans le document EP-1 312 526 A1 , des véhicules ferroviaires dans lesquels le passage entre deux voitures successives se fait sur les deux niveaux. Cependant, dans ce document, l'interconnexion passe entre deux roues reliées directement à la caisse du véhicule ferroviaire et non au droit d'un bogie supportant les extrémités de deux caisses successives et permettant l'entraînement du véhicule ferroviaire. Dans ce document, lorsqu'un tel bogie est prévu, pour les voitures d'extrémités, le plancher est surélevé pour passer au-dessus du bogie, le véhicule ne comprenant qu'un seul niveau au droit du bogie.It has been proposed, for example in the document EP-1 312 526 A1 , railway vehicles in which the passage between two successive cars takes place on both levels. However, in this document, the interconnection passes between two wheels connected directly to the body of the railway vehicle and not in line with a bogie supporting the ends of two successive bodies and allowing the drive of the railway vehicle. In this document, when such a bogie is provided, for the end cars, the floor is raised to pass above the bogie, the vehicle comprising only one level in line with the bogie.

L'interconnexion décrite dans le document EP-1 312 526 A1 n'est donc pas satisfaisante pour les véhicules ferroviaires roulant à vitesse élevée dans lesquels les extrémités de deux voitures successives sont supportées par un bogie. En outre, le véhicule ferroviaire n'est pas optimisé en termes de capacité d'accueil de voyageur.The interconnection described in the document EP-1 312 526 A1 is therefore not satisfactory for railway vehicles traveling at high speed in which the ends of two successive cars are supported by a bogie. In addition, the rail vehicle is not optimized in terms of passenger carrying capacity.

L'un des buts de l'invention est de pallier ces inconvénients en proposant un véhicule ferroviaire dont deux voitures successives sont supportées par un bogie commun tout en permettant une interconnexion à deux niveaux sans surélévation du plancher.One of the aims of the invention is to overcome these drawbacks by proposing a railway vehicle in which two successive cars are supported by a common bogie while allowing interconnection at two levels without raising the floor.

A cet effet, l'invention concerne un véhicule ferroviaire du type précité, dans lequel les voitures sont reliées l'une à l'autre par un passage d'interconnexion, ledit passage s'étendant sensiblement au droit du dispositif d'articulation et comprenant un plancher inférieur reliant les planchers inférieurs des deux voitures et un plancher supérieur reliant les planchers supérieurs des deux voitures, les planchers inférieurs des voitures et du passage d'interconnexion s'étendant sensiblement à la même hauteur et les planchers supérieurs des voitures et du passage d'interconnexion s'étendant sensiblement à la même hauteur, supérieure à la hauteur des planchers inférieurs, le plan des planchers inférieurs étant confondu avec un plan traversant le bogie.To this end, the invention relates to a railway vehicle of the aforementioned type, in which the cars are connected to each other by an interconnection passage, said passage extending substantially in line with the articulation device and comprising a lower floor connecting the lower floors of the two cars and an upper floor connecting the upper floors of the two cars, the lower floors of the cars and the interconnecting passage extending substantially at the same height and the upper floors of the cars and the passage interconnection extending substantially at the same height, greater than the height of the lower floors, the plane of the lower floors being coincident with a plane passing through the bogie.

Prévoir un passage d'interconnexion à deux niveaux permet aux passagers d'un étage supérieur ou inférieur d'une voiture de passer à l'étage supérieur ou inférieur d'une autre voiture sans changer d'étage. Ainsi, la circulation dans le véhicule ferroviaire peut se faire sans passer par des marches ou des rampes, ce qui simplifie le déplacement, notamment pour des passagers à mobilité réduite.Providing a two-level interconnecting passage allows passengers from an upper or lower level of one car to transfer to the upper or lower level of another car without changing floors. Thus, circulation in the railway vehicle can be done without going through steps or ramps, which simplifies movement, in particular for passengers with reduced mobility.

Selon d'autres caractéristiques du véhicule ferroviaire selon l'invention, prises isolément ou selon toutes les combinaisons techniquement possibles :

Dans la description, les termes « sur », « sous », « au-dessus », « en-dessous » sont définis par rapport à une direction d'élévation d'un véhicule ferroviaire lorsqu'il est disposé sur des rails, c'est-à-dire une direction sensiblement verticale lorsque le train circule. La direction longitudinale est définie par la direction de circulation du véhicule ferroviaire et la direction transversale est la direction sensiblement perpendiculaire à la direction longitudinale et à la direction d'élévation du véhicule ferroviaire.In the description, the terms "on", "under", "above", "below" are defined with respect to a direction of elevation of a railway vehicle when it is arranged on rails, c ie a substantially vertical direction when the train is running. The longitudinal direction is defined by the direction of movement of the railway vehicle and the transverse direction is the direction substantially perpendicular to the longitudinal direction and to the direction of elevation of the railway vehicle.

En référence aux figures 1 à 4, on décrit un bogie 1 et un dispositif d'articulation 2 d'un véhicule ferroviaire 4 comprenant au moins deux voitures 6 adjacentes en vue de former un véhicule ferroviaire à deux niveaux dont l'interconnexion permet une circulation sur les deux niveaux, comme cela sera décrit ultérieurement.With reference to figures 1 to 4 , a bogie 1 and an articulation device 2 of a railway vehicle 4 comprising at least two adjacent cars 6 are described with a view to forming a railway vehicle with two levels, the interconnection of which allows circulation on the two levels, as will be described later.

Le bogie 1 s'étend sous et entre deux voitures 6 adjacentes et est agencé pour supporter les caisses 8 de ces voitures. Plus particulièrement, le bogie 1 est agencé pour supporter les extrémités 10, en regard l'une de l'autre, des caisses 8 des voitures 6 adjacentes.The bogie 1 extends under and between two adjacent cars 6 and is arranged to support the bodies 8 of these cars. More particularly, the bogie 1 is arranged to support the ends 10, facing each other, of the bodies 8 of the adjacent cars 6.

Selon l'exemple de réalisation représenté sur la figure 1, le bogie 1 comprend un châssis 12 comprenant deux longerons longitudinaux 14 s'étendant sensiblement selon la direction longitudinale de circulation du véhicule ferroviaire et espacés l'un de l'autre selon la direction transversale sensiblement perpendiculaire à la direction longitudinale et à la direction d'élévation du véhicule ferroviaire.According to the embodiment shown in the figure 1 , the bogie 1 comprises a frame 12 comprising two longitudinal beams 14 extending substantially along the longitudinal direction of movement of the railway vehicle and spaced from each other along the transverse direction substantially perpendicular to the longitudinal direction and to the direction of elevation of the railway vehicle.

Deux roues 16 sont montées sur chaque longeron 14, à chacune des parties extrêmes longitudinales de celui-ci, de sorte qu'une paire de roues 16 s'étend de chaque côté du châssis 12. Plus particulièrement, chaque roue 16 comprend un arbre individuel 18 monté en rotation autour d'un axe transversal sur une boîte d'essieu 20. Par arbre individuel, on entend que chaque roue 16 est mobile en rotation par rapport au châssis indépendamment des autres, à la différence d'un bogie traditionnel dans lequel un essieu relie généralement les roues deux à deux et entraîne simultanément deux roues en rotation. Chaque partie extrême d'un longeron longitudinal 14 repose sur une boîte d'essieu 20 par l'intermédiaire d'une suspension primaire 22 autorisant un débattement vertical du châssis 1 par rapport aux roues 16. Les roues sont montées de sorte à s'étendre, selon la direction transversale, à l'intérieur du gabarit défini par le contour du châssis 12, les boîtes d'essieu 20 étant disposées du côté extérieur des roues 16.Two wheels 16 are mounted on each spar 14, at each of the longitudinal end portions thereof, so that a pair of wheels 16 extends on each side of the frame 12. More particularly, each wheel 16 comprises an individual shaft 18 rotatably mounted about a transverse axis on an axle box 20. By individual shaft is meant that each wheel 16 is rotatable relative to the frame independently of the others, unlike a traditional bogie in which an axle generally connects the wheels two by two and simultaneously drives two wheels in rotation. Each end part of a longitudinal spar 14 rests on an axle box 20 via a primary suspension 22 allowing vertical movement of the frame 1 relative to the wheels 16. The wheels are mounted so as to extend , in the transverse direction, inside the template defined by the contour of the chassis 12, the axle boxes 20 being arranged on the outer side of the wheels 16.

Dans le cas d'un bogie 1 motorisé, chaque longeron 14 porte en outre au moins un moteur 24 agencé pour entraîner en rotation les deux roues 16 portées par le longeron. Le moteur est ainsi relié à la boîte d'essieu 20 de chaque roue 16 par des moyens de transmission. Ces moyens de transmission sont par exemple du même type que ceux décrits dans le document EP-1 270 359 A1 et ne seront pas décrits plus en détail ici. Chaque moteur 24 est porté par son longeron 14 entre les deux roues 16 portées par ledit longeron 14.In the case of a motorized bogie 1, each spar 14 also carries at least one motor 24 arranged to drive in rotation the two wheels 16 carried by the spar. The motor is thus connected to the axle box 20 of each wheel 16 by transmission means. These transmission means are for example of the same type as those described in the document EP-1 270 359 A1 and will not be described in more detail here. Each motor 24 is carried by its spar 14 between the two wheels 16 carried by said spar 14.

Le bogie 1 comprend en outre un dispositif de freinage comprenant quatre pinces de frein 26, disposées chacune, autour d'une partie d'une des roues 16 de sorte à freiner les roues 16 de façon connue lorsque le dispositif de freinage est actionné. Les pinces de frein 26 sont chacune disposée du côté intérieur des roues 16 selon la direction longitudinale, c'est-à-dire qu'elles s'étendent vers le centre du bogie 1 selon la direction longitudinale et non vers l'extérieur, comme cela est habituellement le cas. Ainsi, les pinces de frein 26 s'étendent deux à deux l'une en regard de l'autre selon la direction de circulation de sorte que chaque pince 26 s'étend entre les roues d'une des paires de roues selon la direction longitudinale.The bogie 1 further comprises a braking device comprising four brake calipers 26, arranged each, around a part of one of the wheels 16 so as to brake the wheels 16 in a known manner when the braking device is actuated. The brake callipers 26 are each arranged on the inside of the wheels 16 in the longitudinal direction, that is to say they extend towards the center of the bogie 1 in the longitudinal direction and not outwards, as this is usually the case. Thus, the brake calipers 26 extend in pairs opposite each other in the direction of travel so that each caliper 26 extends between the wheels of one of the pairs of wheels in the longitudinal direction. .

Les longerons latéraux 14 sont reliés l'un à l'autre par au moins une traverse 28 s'étendant selon la direction transversale entre les deux longerons 14. Selon le mode de réalisation représenté sur les figures, les longerons 14 sont reliés par deux traverses 28 espacées l'une de l'autre selon la direction longitudinale. Les traverses 28 comprennent au moins une partie centrale s'étendant dans un plan abaissé entre les longerons longitudinaux, c'est-à-dire dans un plan s'étendant sous le plan défini par les axes des roues 16.The side beams 14 are connected to each other by at least one crosspiece 28 extending in the transverse direction between the two beams 14. According to the embodiment shown in the figures, the beams 14 are connected by two crosspieces 28 spaced from each other in the longitudinal direction. The crosspieces 28 comprise at least a central part extending in a lowered plane between the longitudinal beams, that is to say in a plane extending below the plane defined by the axles of the wheels 16.

Un espace 30 est délimité, dans le plan des traverses 28, par les deux traverses 28 selon la direction longitudinale et par les longerons longitudinaux 14 selon la direction transversale. L'espace 30 s'étend par exemple entre les deux moteurs 24 selon la direction transversale.A space 30 is delimited, in the plane of the crosspieces 28, by the two crosspieces 28 in the longitudinal direction and by the longitudinal beams 14 in the transverse direction. The space 30 extends for example between the two motors 24 in the transverse direction.

Le bogie 1 comprend en outre une première surface de butée 32 et une deuxième surface de butée 34 s'étendant dans l'espace 30, de part et d'autre de celui-ci selon la direction longitudinale. Les surfaces de butées 32 et 34 s'étendent ainsi l'une en regard de l'autre de part et d'autre de l'espace 30 selon la direction longitudinale, par exemple sensiblement au centre du bogie 1 selon la direction transversale. Les première et deuxième surfaces de butée 32 et 34 sont par exemple portées chacune par une des traverses 28 délimitant l'espace 30, comme cela est plus particulièrement visible sur la figure 4. Les première et deuxième surfaces de butées 32 et 34 sont par exemple formées par des patins s'étendant chacun dans un plan défini par la direction transversale et par la direction d'élévation. Selon le mode de réalisation représenté sur les figures, un élément d'absorption, par exemple en caoutchouc, 36 est disposé entre chaque surface de butées 32, 34 et la traverse 28 qui porte cette surface de butée 32, 34.The bogie 1 further comprises a first abutment surface 32 and a second abutment surface 34 extending in the space 30, on either side of the latter in the longitudinal direction. The abutment surfaces 32 and 34 thus extend opposite each other on either side of the space 30 in the longitudinal direction, for example substantially at the center of the bogie 1 in the transverse direction. The first and second abutment surfaces 32 and 34 are for example each carried by one of the crosspieces 28 delimiting the space 30, as is more particularly visible on the figure 4 . The first and second abutment surfaces 32 and 34 are for example formed by pads each extending in a plane defined by the transverse direction and by the direction of elevation. According to the embodiment shown in the figures, an absorption element, for example made of rubber, 36 is arranged between each abutment surface 32, 34 and the crosspiece 28 which carries this abutment surface 32, 34.

Selon le mode de réalisation représenté sur les figures, le bogie 1 comprend en outre des traverses secondaires 38 reliant entre elles les boîtes d'essieu 20, ces traverses secondaires 38 étant disposées de part et d'autre de chaque roue 16, à une hauteur sensiblement identique à celle des traverses 28, c'est-à-dire une hauteur abaissée sous le plan défini par les arbres 18 des roues 16. Ces traverses secondaires 38 assurent le maintien de l'écartement et du parallélisme entre les roues 16.According to the embodiment shown in the figures, the bogie 1 further comprises secondary crosspieces 38 interconnecting the axle boxes 20, these secondary crosspieces 38 being arranged on either side of each wheel 16, at a height substantially identical to that of the crosspieces 28, that is to say a height lowered below the plane defined by the shafts 18 of the wheels 16. These secondary crosspieces 38 maintain the spacing and the parallelism between the wheels 16.

Le bogie ci-dessus permet d'avoir un volume disponible important entre les longerons longitudinaux 14 au-dessus des traverses 28, comme cela est visible sur les figures 1 à 3. En effet, le bogie 1 ne comprend pas d'éléments disposés entre les deux longerons 14 au-dessus du plan défini par les traverses 28. Ce volume va permettre le passage d'un plancher d'interconnexion abaissé, comme cela va être décrit ultérieurement. Il est entendu qu'une autre structure de bogie peut être envisagée, en dehors de l'espace 30 et des surfaces de butées 32 et 34, tant qu'un volume est laissé libre pour le passage de l'interconnexion. A titre d'exemple, le bogie peut être un bogie entraîné, c'est-à-dire dépourvu de moteur, ou toutes les roues du bogie ne sont pas nécessairement entraînées en rotation par un moteur.The bogie above makes it possible to have a large available volume between the longitudinal side members 14 above the crosspieces 28, as is visible on the figures 1 to 3 . Indeed, the bogie 1 does not include elements arranged between the two longitudinal members 14 above the plane defined by the crosspieces 28. This volume will allow the passage of a lowered interconnecting floor, as will be described later. . It is understood that another bogie structure can be envisaged, apart from the space 30 and the abutment surfaces 32 and 34, as long as a volume is left free for the passage of the interconnection. By way of example, the bogie can be a driven bogie, that is to say without a motor, or all the wheels of the bogie are not necessarily driven in rotation by a motor.

Les extrémités 10 en regard des caisses 8 des deux voitures 6 adjacentes sont reçues par des suspensions secondaires 40 prévues sur les longerons longitudinaux 14, permettant un débattement vertical des caisses 8 par rapport au bogie 1.The ends 10 opposite the bodies 8 of the two adjacent cars 6 are received by secondary suspensions 40 provided on the longitudinal beams 14, allowing a vertical movement of the bodies 8 with respect to the bogie 1.

Les deux caisses 8 sont articulées entre elles par le dispositif d'articulation 2 fixé aux deux caisses de sorte à former une liaison articulée entre les deux caisses permettant d'absorber les débattements entre les deux caisses 8. Plus particulièrement, le dispositif d'articulation 2 comprend par exemple un premier élément d'articulation 42 fixé à l'extrémité 10 de l'une des caisses 8, et un deuxième élément d'articulation 44 fixé à l'extrémité 10 de l'autre caisse 8, les premier et deuxième éléments d'articulation 42 et 44 étant reliés l'un à l'autre de sorte à former une liaison articulée entre les deux caisses. La liaison entre les deux éléments d'articulation 42 et 44 forme par exemple une liaison rotule 46 autorisant un débattement dans toutes les directions entre les caisses.The two boxes 8 are hinged together by the hinge device 2 fixed to the two boxes so as to form an articulated connection between the two boxes making it possible to absorb the deflections between the two boxes 8. More particularly, the hinge device 2 comprises for example a first hinge element 42 fixed to the end 10 of one of the boxes 8, and a second hinge element 44 fixed to the end 10 of the other box 8, the first and second hinge elements 42 and 44 being connected to each other so as to form an articulated connection between the two boxes. The connection between the two hinge elements 42 and 44 forms, for example, a ball joint 46 allowing movement in all directions between the boxes.

Les éléments d'articulation 42 et 44 sont fixés aux caisses 8 de sorte que le dispositif d'articulation 2 s'étend dans l'espace 30 entre les surfaces de butées 32 et 34, comme plus particulièrement visible sur la figure 4. Le dispositif d'articulation 2 et l'espace 30 sont dimensionnés de telle manière qu'un débattement existe selon la direction longitudinale. En d'autres termes, la distance séparant la première surface de butée 32 de la deuxième surface de butée 34 selon la direction longitudinale est supérieure à la dimension du dispositif d'articulation 2 selon la direction longitudinale.The articulation elements 42 and 44 are fixed to the boxes 8 so that the articulation device 2 extends into the space 30 between the abutment surfaces 32 and 34, as more particularly visible on the figure 4 . The articulation device 2 and the space 30 are dimensioned in such a way that there is movement in the longitudinal direction. In other words, the distance separating the first abutment surface 32 from the second abutment surface 34 in the longitudinal direction is greater than the dimension of the hinge device 2 in the longitudinal direction.

Le premier élément d'articulation 42 comprend une surface de contre butée 48 s'étendant en regard de la première surface de butée 32 et le deuxième élément d'articulation 44 comprend une surface de contre butée 50 s'étendant en regard de la deuxième surface de butée 34. Les surfaces de contre butée portent en outre les moyens de fixation 52 à la caisse 8.The first articulation element 42 comprises a counter-abutment surface 48 extending opposite the first abutment surface 32 and the second articulation element 44 comprises a counter-abutment surface 50 extending opposite the second surface abutment 34. The counter-abutment surfaces also carry the fixing means 52 to the body 8.

Ainsi, lorsque le véhicule ferroviaire est monté et lorsqu'il circule selon une première direction longitudinale de circulation allant de la première surface de butée 32 vers la deuxième surface de butée 34, le bogie 1 se déplace jusqu'à ce que la première surface de butée 32 entre en contact avec la surface de contre butée 48 du premier élément d'articulation 42, de sorte que le bogie 1 entraîne le déplacement des voitures 6 par l'intermédiaire du dispositif d'articulation 2 selon cette première direction longitudinale. De façon similaire, lorsque le véhicule ferroviaire se déplace selon une deuxième direction longitudinale de circulation, opposée à la première direction longitudinale, allant de la deuxième surface de butée 34 vers la première surface de butée, le bogie 1 se déplace jusqu'à ce que la deuxième surface de butée 34 entre en contact avec la surface de contre butée 50 du deuxième élément d'articulation 44, de sorte que le bogie 1 entraîne le déplacement des voitures 6 par l'intermédiaire du dispositif d'articulation 2 selon cette deuxième direction longitudinale.Thus, when the railway vehicle is mounted and when it is traveling in a first longitudinal direction of travel going from the first abutment surface 32 towards the second abutment surface 34, the bogie 1 moves until the first surface of abutment 32 comes into contact with the counter-abutment surface 48 of the first articulation element 42, so that the bogie 1 causes the movement of the cars 6 via the hinge device 2 in this first longitudinal direction. Similarly, when the railway vehicle is moving in a second longitudinal direction of movement, opposite to the first longitudinal direction, going from the second abutment surface 34 towards the first abutment surface, the bogie 1 moves until the second abutment surface 34 comes into contact with the counter-abutment surface 50 of the second articulation element 44, so that the bogie 1 causes the movement of the cars 6 via the articulation device 2 in this second direction longitudinal.

Comme le dispositif d'articulation s'étend dans l'espace 30, ce dispositif d'articulation n'occupe pas non plus le volume libre entre les longerons longitudinaux 14 au-dessus des traverses 28. Ainsi, ce volume est laissé libre pour le passage d'un plancher d'interconnexion bas, comme cela va à présent être décrit.As the hinge device extends into the space 30, this hinge device does not occupy the free volume between the longitudinal beams 14 above the crosspieces 28 either. Thus, this volume is left free for the passage of a low interconnecting floor, as will now be described.

Chaque voiture 6 est une voiture à deux niveaux, comme cela est représenté sur la figure 5. Ainsi, chaque voiture 6 comprend un plancher inférieur 54 et un plancher supérieur 56, disposés l'un au-dessus de l'autre de sorte à définir un niveau inférieur 58 et un niveau supérieur 60. Le plancher inférieur 54 et le plancher supérieur 56 sont par exemple sensiblement plans et horizontaux de sorte que les voitures peuvent être franchies sans difficulté. En outre, les planchers inférieur 54 et supérieur 56 d'une voiture s'étendent au même niveau que les planchers inférieur 54 et supérieur 56 de l'autre niveau, c'est-à-dire que les planchers inférieur 54 et supérieur 56 de toutes les voitures s'étendent à la même hauteur, la hauteur des planchers supérieurs 56 étant supérieure à celle des planchers inférieurs 54. A titre d'exemple, le plancher inférieur 54 s'étend à une hauteur sensiblement comprise entre 530 et 550 mm et le plancher supérieur 56 s'étend à une hauteur sensiblement comprise entre 2380 et 2400 mm. Les hauteurs données ci-dessus sont dépendantes du gabarit dans lequel le véhicule doit s'inscrire.Each car 6 is a two-level car, as shown in the figure 5 . Thus, each car 6 comprises a lower floor 54 and an upper floor 56, arranged one above the other so as to define a lower level 58 and an upper level 60. The lower floor 54 and the upper floor 56 are for example substantially flat and horizontal so that cars can be passed without difficulty. Furthermore, the lower 54 and upper 56 floors of one car extend at the same level as the lower 54 and upper 56 floors of the other level, i.e. the lower 54 and upper 56 floors of all the cars extend at the same height, the height of the upper floors 56 being greater than that of the lower floors 54. By way of example, the lower floor 54 extends to a height substantially between 530 and 550 mm and the upper floor 56 extends to a height substantially between 2380 and 2400 mm. The heights given above are dependent on the size in which the vehicle must fit.

Les voitures 6 sont reliées l'une à l'autre par un passage d'interconnexion 62 s'étendant sensiblement au droit du dispositif d'articulation 2 et permettant le passage d'une voiture à l'autre aux usagers du véhicule ferroviaire. A cet effet, le passage d'interconnexion 62 comprend un plancher inférieur, reliant les planchers inférieurs 54 des voitures 6 et s'étendant à la même hauteur que ces planchers, et un plancher supérieur, reliant les planchers supérieurs 56 des voitures 6 et s'étendant à la même hauteur que ces planchers. Ainsi, les utilisateurs du véhicule ferroviaire n'ont pas besoin de changer de niveau pour passer d'une voiture à l'autre, comme c'est usuellement le cas dans les véhicules ferroviaires à deux étages. En outre, le passage d'une voiture à l'autre par le niveau inférieur peut se faire sans franchir de marche ou de rampe puisque les planchers inférieurs s'étendent tous à la même hauteur. La circulation dans le véhicule ferroviaire est ainsi facilitée, en particulier pour les personnes à mobilité réduite.The cars 6 are connected to each other by an interconnection passage 62 extending substantially in line with the hinge device 2 and allowing users of the rail vehicle to pass from one car to the other. For this purpose, the interconnection passage 62 comprises a lower floor, connecting the lower floors 54 of the cars 6 and extending at the same height as these floors, and an upper floor, connecting the upper floors 56 of the cars 6 and s extending to the same height as these floors. Thus, the users of the railway vehicle do not need to change level to pass from one car to another, as is usually the case in double-decker railway vehicles. In addition, the passage from one car to another via the lower level can be done without crossing a step or a ramp since the lower floors all extend at the same height. Movement in the rail vehicle is thus facilitated, in particular for people with reduced mobility.

La disposition du plancher inférieur du passage d'interconnexion 62 à la même hauteur que celle des planchers inférieurs 54 des voitures est rendue possible par l'agencement du bogie 1, qui présente un volume libre important entre les longerons longitudinaux 14. Ainsi, le plancher inférieur du passage d'interconnexion 62 peut s'étendre dans un plan confondu avec l'un des plans du bogie 1 et plus particulièrement avec un plan voisin du plan défini par les traverses 28, comme représenté sur la figure 4.The arrangement of the lower floor of the interconnection passage 62 at the same height as that of the lower floors 54 of the cars is made possible by the arrangement of the bogie 1, which has a large free volume between the longitudinal beams 14. Thus, the floor bottom of the interconnection passage 62 can extend in a plane coincident with one of the planes of the bogie 1 and more particularly with a plane close to the plane defined by the crosspieces 28, as represented on the figure 4 .

Le véhicule ferroviaire décrit ci-dessus peut être mis en oeuvre, comme représenté sur les figures 6 et 7, avec plus de deux voitures 6 et avec une capacité d'accueil de voyageurs optimisée.The railway vehicle described above can be implemented, as shown in the figures 6 and 7 , with more than two 6 cars and with an optimized passenger capacity.

Le passage d'interconnexion décrit ci-dessus peut être utilisé dans des véhicules ferroviaires à deux niveaux et dont les voitures sont articulées entre elles par un dispositif d'articulation différent de celui décrit ci-dessus. Par exemple, les voitures pourraient être articulées entre elles de façon classique et dont l'entraînement se ferait directement par les bogies sans passer par une mise en butée du dispositif d'articulation sur des surfaces de butée correspondantes.The interconnection passage described above can be used in railway vehicles with two levels and whose cars are articulated to one another by an articulation device different from that described above. For example, the cars could be articulated to each other in a conventional manner and the drive of which would be done directly by the bogies without going through abutment of the articulation device on corresponding abutment surfaces.

Selon le mode de réalisation représenté sur les figures 6 et 7, le véhicule ferroviaire comprend ainsi cinq voitures 6 à deux niveaux et deux voitures d'extrémités 64, comprenant chacune un niveau et un poste de pilotage. Les voitures à deux niveaux 6 sont reliées les unes aux autres par un passage d'interconnexion 62 tel que décrit ci-dessus. Un tel véhicule ferroviaire est apte à recevoir 600 passagers. En outre, le bogie est adapté pour des trains circulant à des vitesses élevées allant jusqu'à 200 km/h, voire au-delà, tout en ayant une structure permettant de recevoir un plancher inférieur abaissé, comme décrit précédemment.According to the embodiment shown in the figures 6 and 7 , the railway vehicle thus comprises five cars 6 at two levels and two end cars 64, each comprising a level and a cockpit. The bi-level cars 6 are connected to each other by an interconnecting passage 62 as described above. Such a railway vehicle is capable of receiving 600 passengers. In addition, the bogie is suitable for trains traveling at high speeds of up to 200 km/h, or even beyond, while having a structure making it possible to receive a lowered lower floor, as described previously.

Il est entendu que la structure du dispositif d'articulation 2 pourrait être différente de celle décrite ci-dessus, tant que ce dispositif d'articulation est apte à entrer en contact avec les surfaces de butée du bogie 1 pour que le bogie entraîne le déplacement des voitures du véhicule.It is understood that the structure of the articulation device 2 could be different from that described above, as long as this articulation device is capable of coming into contact with the abutment surfaces of the bogie 1 so that the bogie drives the displacement vehicle cars.
