The two moving panels and the fixed panel are connected by a deformable mechanism (5) formed by pivoted levers (6) and linking bars (7). The levers and bars form a deformable parallelogram which guides the moving panel when the vehicle sections move relative to one another, especially on bends or turns.

Description

L'invention concerne un plancher permettant de circuler entre deux véhicules reliés ensemble par une liaison articulée.The invention relates to a floor allowing movement between two vehicles. linked together by an articulated link.

Ce plancher est notamment destiné à un couloir d'intercirculation de passagers entre deux voitures d'un véhicule ferroviaire, tel que, par exemple, des rames de tramway, métropolitain ou train, ou d'un véhicule routier, tel que, par exemple, un autobus.This floor is in particular intended for a passenger interconnection corridor between two cars of a railway vehicle, such as, for example, trainsets tram, metropolitan or train, or a road vehicle, such as, for example, a bus.

On connaít déjà de tels planchers d'intercirculation, par les documents WO-A-95/06580 et EP-B-0722875.We already know such floors of traffic, by documents WO-A-95/06580 and EP-B-0722875.

Notamment, le document EP-B- 0 722 873, décrit une passerelle d'intercommunication comprenant plusieurs éléments coulissant les uns dans les autres et un châssis à ciseaux permettant d'éviter la formation de lacunes entre les éléments dans les virages.In particular, document EP-B- 0 722 873 describes a gateway intercom system comprising several elements sliding together the others and a scissor chassis to prevent the formation of gaps between the elements in the turns.

Dans le dispositif décrit par le document EP-B- 0 722 873, le châssis est sous tension de ressort ce qui a pour effet que les différents éléments se remettent en place après leur déviation dans un virage.In the device described in document EP-B- 0 722 873, the chassis is under spring tension which causes the different elements to recover in place after their deviation in a turn.

Un tel dispositif présente l'inconvénient de comprendre de nombreuses pièces en frottement, sensibles à l'usure. Par ailleurs, du fait du grand nombre de pièces, le montage de ce type de passerelle est relativement compliqué.Such a device has the disadvantage of comprising many parts in friction, sensitive to wear. Furthermore, due to the large number of parts, the assembly of this type of gangway is relatively complicated.

La présente invention a pour objet de réaliser un plancher de circulation entre véhicules comprenant un nombre réduit de pièces mobiles afin de limiter l'usure par frottement, tout en étant apte à s'adapter aux mouvements relatifs entre les véhicules.The object of the present invention is to provide a circulation floor between vehicles with a reduced number of moving parts to limit wear by friction, while being able to adapt to the relative movements between the vehicles.

Ce plancher présente également l'avantage de pouvoir être monté facilement sur différents types de véhicules.This floor also has the advantage of being easily mounted on different types of vehicles.

A cet effet, le plancher selon l'invention comprend une première palette pouvant être fixée à l'extrémité de l'un des véhicules et une seconde palette pouvant être fixée à l'extrémité de l'autre véhicule. Ces deux palettes fixes sont recouvertes chacune partiellement par une palette mobile, et elles sont reliées l'une à l'autre par deux organes déformables.To this end, the floor according to the invention comprises a first pallet which can be fixed to the end of one of the vehicles and a second pallet that can be attached to the end of the other vehicle. These two fixed pallets are each partially covered by a movable pallet, and they are connected to each other by two organs deformable.

Chaque organe déformable comprend deux bielles articulées l'une à l'autre et respectivement reliées de façon articulée à l'une et à l'autre des dites palettes fixes. Chaque bielle est reliée à l'autre bielle par deux biellettes qui sont articulées ensemble et fixées de façon articulée à chacune des bielles en un point compris entre un point d'articulation de la bielle sur la palette fixe et le point d'articulation commun des deux bielles.Each deformable member comprises two connecting rods hinged to each other and respectively connected in an articulated manner to one and to the other of said pallets fixed. Each connecting rod is connected to the other connecting rod by two rods which are hinged together and hingedly attached to each of the connecting rods in one point between a link point of the connecting rod on the fixed pallet and the common point of articulation of the two connecting rods.

Les deux biellettes forment ainsi avec les deux bielles un parallélogramme déformable sensiblement horizontal, le point d'articulation commun des deux biellettes étant solidaire de la palette mobile et mobile en rotation par rapport à cette palette mobile.The two rods thus form with the two rods a parallelogram substantially horizontal deformable, the common point of articulation of the two rods being integral with the movable and movable pallet in rotation relative to this movable pallet.

La palette mobile est ainsi guidée cinématiquement par le parallélogramme déformable lors des mouvements des véhicules.The movable pallet is thus kinematically guided by the parallelogram deformable during vehicle movements.

D'autres particularités et avantages de l'invention apparaítront encore dans la description ci-après.Other features and advantages of the invention will become apparent in the description below.

  • la figure 1 est une vue de dessus du plancher selon l'invention ;
  • la figure 2 représente une vue en coupe du plancher selon l'invention;
  • la figure 3 représente un schéma de principe du plancher vu de dessus lors du franchissement d'un virage des véhicules.
In the appended drawings given by way of nonlimiting examples:
  • Figure 1 is a top view of the floor according to the invention;
  • Figure 2 shows a sectional view of the floor according to the invention;
  • Figure 3 shows a block diagram of the floor seen from above when crossing a bend in vehicles.

La figure 1 représente un plancher 1 permettant de circuler entre deux véhicules, non représentés, reliés ensemble par une liaison articulée non représentée.FIG. 1 represents a floor 1 allowing circulation between two vehicles, not shown, connected together by an articulated link not represented.

Le plancher comprend :

  • une première palette 2 pouvant être fixée à l'extrémité de l'un des véhicules ;
  • une seconde palette 3 pouvant être fixée à l'extrémité de l'autre véhicule ;
  • une palette mobile 4 reposant sur les palettes fixes 2 et 3.
The floor includes:
  • a first pallet 2 which can be fixed to the end of one of the vehicles;
  • a second pallet 3 which can be fixed to the end of the other vehicle;
  • a movable pallet 4 resting on the fixed pallets 2 and 3.

Les deux palettes fixes 2, 3 sont ainsi recouvertes chacune partiellement par la palette mobile 4, tel que représenté sur les figures 2 et 3.The two fixed pallets 2, 3 are thus each partially covered by the movable pallet 4, as shown in FIGS. 2 and 3.

Les palettes fixes et mobiles sont d'un matériau rigide et résistant, apte à supporter de légères déformations, tel que par exemple du métal ou un composite.The fixed and mobile pallets are of a rigid and resistant material, suitable for withstand slight deformations, such as for example metal or a composite.

Les deux palettes fixes 2, 3 sont reliées l'une à l'autre par deux organes déformables 5 de même type.The two fixed pallets 2, 3 are connected to each other by two members deformable 5 of the same type.

Chaque organe déformable 5 comprend deux bielles 6 et deux biellettes 7.Each deformable member 5 comprises two connecting rods 6 and two connecting rods 7.

Les deux bielles 6 sont articulées l'une à l'autre par leurs extrémités au moyen d'une articulation 8 dont l'axe est perpendiculaire au plan de la palette mobile 4.The two connecting rods 6 are articulated to one another by their ends by means an articulation 8 whose axis is perpendicular to the plane of the movable pallet 4.

Les extrémités des bielles 6 opposées à l'articulation 8 sont reliées de façon articulée à l'une et à l'autre des dites palettes fixes 2, 3.The ends of the connecting rods 6 opposite the articulation 8 are connected so articulated to both of said fixed pallets 2, 3.

Chaque bielle 6 est reliée à l'autre bielle 6 par deux biellettes 7.Each connecting rod 6 is connected to the other connecting rod 6 by two connecting rods 7.

Les biellettes 7 sont reliées par une articulation 9, et elles sont fixées par des articulations 10 à chacune des bielles 6.The links 7 are connected by a hinge 9, and they are fixed by joints 10 at each of the connecting rods 6.

Les articulations 10 sont ainsi situées sur les bielles 6 en un point compris entre un point d'articulation de la bielle sur la palette fixe et l'articulation commune 8 des deux bielles 6.The joints 10 are thus located on the connecting rods 6 at a point between a point of articulation of the connecting rod on the fixed pallet and the common articulation 8 of the two connecting rods 6.

Dans le mode de réalisation représenté sur les figures, les articulations 10 sont placées au milieu des bielles 6.In the embodiment shown in the figures, the joints 10 are placed in the middle of the connecting rods 6.

Les deux biellettes 7 forment ainsi avec les deux bielles 6 un parallélogramme déformable 5 sensiblement horizontal. The two connecting rods 7 thus form with the two connecting rods 6 a parallelogram deformable 5 substantially horizontal.

L'articulation 9, commune aux deux biellettes 7, est solidaire de la palette mobile 4, tout en étant mobile en rotation autour d'un axe perpendiculaire à cette palette mobile.The joint 9, common to the two links 7, is integral with the movable pallet 4, while being movable in rotation about an axis perpendicular to this mobile pallet.

Cette articulation commune 9 est située sur un axe X dit médian, perpendiculaire à l'axe longitudinal Y, et définissant symétrie longitudinale de la palette mobile 4. Les axes X et Y sont représentés sur la figure 1, la direction longitudinale étant définie comme étant celle du véhicule sur lequel les palettes peuvent être montées.This common articulation 9 is located on a so-called median axis X, perpendicular to the longitudinal axis Y, and defining longitudinal symmetry of the movable pallet 4. The axes X and Y are shown in Figure 1, the longitudinal direction being defined as that of the vehicle on which the pallets can be mounted.

Les extrémités des bielles 6 opposées à leur articulation commune 8 sont fixées chacune de façon articulée à un bras 11, lui-même relié de façon articulée à une palette fixe 2, 3.The ends of the connecting rods 6 opposite their common articulation 8 are fixed each hinged to an arm 11, itself hingedly connected to a fixed pallet 2, 3.

Chaque articulation 12 reliant une bielle 6 à un bras 11 présente un axe perpendiculaire au plan de la palette mobile 4.Each articulation 12 connecting a connecting rod 6 to an arm 11 has an axis perpendicular to the plane of the movable pallet 4.

L'axe de l'articulation 13 reliant un bras 11 à une palette fixe 2, 3, est parallèle au plan de la palette fixe 2, 3 et perpendiculaire à l'axe Y longitudinale de la palette fixe 2, 3.The axis of the articulation 13 connecting an arm 11 to a fixed pallet 2, 3, is parallel in the plane of the fixed pallet 2, 3 and perpendicular to the longitudinal Y axis of the fixed pallet 2, 3.

Dans le mode de réalisation représenté sur la figure 2, l'axe de l'articulation 13 est fixé sur une chape 14 fixée par des vis sur la face inférieure des palettes fixes 2, 3.In the embodiment shown in Figure 2, the axis of the joint 13 is fixed on a yoke 14 fixed by screws on the underside of the pallets fixed 2, 3.

L'association des deux articulations 13 permet ainsi de compenser les variations de hauteur induites par le mouvement relatif des deux véhicules.The association of the two joints 13 thus makes it possible to compensate for the variations height induced by the relative movement of the two vehicles.

Les axes des bielles 6 et biellettes 7, tels que représentés sur la figure 2, sont sensiblement parallèles au plan de la palette mobile 4, les axes des articulations 8, 9, 10 et 12 étant perpendiculaires à ce plan.The axes of the rods 6 and rods 7, as shown in Figure 2, are substantially parallel to the plane of the movable pallet 4, the axes of the joints 8, 9, 10 and 12 being perpendicular to this plane.

Les axes d'articulation de chaque parallélogramme sont donc perpendiculaires au plan formé par les palettes 2, 3, 4 lorsqu'il n'existe pas de dénivelé entre les palettes 2, 3.The axes of articulation of each parallelogram are therefore perpendicular on the plane formed by the pallets 2, 3, 4 when there is no difference in level between the pallets 2, 3.

Dans le mode de réalisation représenté sur la figure 1, les palettes fixes 2, 3 et mobile 4 étant alignées selon la direction longitudinale, les deux parallélogrammes déformables 5 sont symétriques entre eux par rapport à l'axe longitudinal Y de la palette mobile, le point d'articulation commun 8 des bielles 6 de chaque parallélogramme étant proche dudit axe longitudinal Y.In the embodiment shown in FIG. 1, the fixed pallets 2, 3 and mobile 4 being aligned in the longitudinal direction, the two deformable parallelograms 5 are symmetrical to each other with respect to the longitudinal axis Y of the movable pallet, the point of articulation common 8 of the connecting rods 6 of each parallelogram being close to said axis longitudinal Y.

Les longueurs des bielles 6 et des biellettes 7 sont telles que, pour chaque parallélogramme 5, l'articulation 9 fixée sur la palette mobile et les deux articulations 12 reliées aux palettes fixes par les bras 11 sont toujours alignées quelque soit la position relative des palettes fixes.The lengths of the connecting rods 6 and of the connecting rods 7 are such that, for each parallelogram 5, the joint 9 fixed on the movable pallet and the two joints 12 connected to the fixed pallets by the arms 11 are always aligned whatever the relative position of the fixed pallets.

Cette caractéristique permet à la palette mobile 4 de revenir dans l'axe des palettes fixes 2, 3, lorsque les véhicules suivent une direction rectiligne.This characteristic allows the movable pallet 4 to return to the axis of the fixed pallets 2, 3, when the vehicles follow a straight direction.

La palette mobile 4 repose sur les palettes fixes 2, 3 par l'intermédiaire d'au moins deux patins 15 de glissement répartis régulièrement sur chacun de ses bords 20 parallèles à l'axe médian X.The movable pallet 4 rests on the fixed pallets 2, 3 by means of at at least two sliding pads 15 distributed regularly on each of its edges 20 parallel to the median axis X.

Dans le mode de réalisation représenté sur les figures, chaque bord 20 de la palette mobile 4 comprend trois patins 15 répartis régulièrement.In the embodiment shown in the figures, each edge 20 of the movable pallet 4 comprises three pads 15 distributed regularly.

Chaque patin 15 est fixé sur le bord de la palette mobile 4 au moyen d'une charnière 16 fixée par des vis sur le bord de la palette mobile. L'axe 17 de la charnière est parallèle au bord 20 de la palette mobile et perpendiculaire à la direction longitudinale de celle-ci.Each pad 15 is fixed to the edge of the movable pallet 4 by means of a hinge 16 fixed by screws on the edge of the movable pallet. Axis 17 of the hinge is parallel to the edge 20 of the movable pallet and perpendicular to the longitudinal direction thereof.

Les patins 15 sont réalisés en un matériau résistant à l'usure.The pads 15 are made of a wear-resistant material.

Les parallélogrammes déformables 5 sont réglés de sorte que l'espace entre la palette mobile et les palettes fixes soit suffisamment réduit pour empêcher le passage d'objets ou de doigts d'un passager entre les palettes.The deformable parallelograms 5 are adjusted so that the space between the movable pallet and fixed pallets is reduced enough to prevent the passage of objects or fingers of a passenger between the pallets.

Une légère précontrainte appliquée sur la palette mobile permet par ailleurs de compenser le roulis. A slight prestress applied to the movable pallet also allows compensate for roll.

La palette mobile 4 ne repose ainsi pas directement sur les palettes fixes. Les patins 15, reliés à la palette mobile 4, font office de pièces d'usures interchangeables.The movable pallet 4 thus does not rest directly on the fixed pallets. The pads 15, connected to the movable pallet 4, act as wear parts interchangeable.

La surface des palettes fixes 2, 3 sur laquelle les patins 15 sont susceptibles de se déplacer lors des mouvements des véhicules, est lisse, afin de limiter le frottement et l'usure des patins.The surface of the fixed pallets 2, 3 on which the pads 15 are capable of move during vehicle movements, is smooth, in order to limit the friction and wear of the pads.

Les autres surfaces des palettes fixes 2, 3 et mobiles 4 sont rugueuses afin d'éviter les glissades des passagers.The other surfaces of the fixed pallets 2, 3 and mobile 4 are rough so avoid slipping of passengers.

Les dimensions et la forme de la palette mobile 4 sont telles que cette dernière recouvre chacune des palettes fixes 2, 3, selon une surface suffisante de façon à maintenir ce recouvrement quelque soit les positions relatives des deux véhicules.The dimensions and shape of the movable pallet 4 are such that the latter covers each of the fixed pallets 2, 3, in a sufficient area so to maintain this overlap whatever the relative positions of the two vehicles.

La palette mobile 4 présente une souplesse suffisante de manière à pouvoir se déformer et pour rester en contact des palettes fixes 2, 3 en cas de mouvement de roulis et/ou de dénivelé entre les deux véhicules.The movable pallet 4 has sufficient flexibility so that it can be deform and to stay in contact with the fixed pallets 2, 3 in the event of movement roll and / or elevation between the two vehicles.

Les faibles angulations de roulis entre les caisses sont reprises dans le parallélogramme déformable grâce aux jeux et aux déformations élastiques des bielles et biellettes.The low roll angles between the bodies are included in the deformable parallelogram thanks to the games and elastic deformations of the connecting rods and rods.

Les palettes fixes 2 et 3 sont fixées aux véhicules par des vis. Elles peuvent par exemple être fixées sur les caisses des véhicules.The fixed pallets 2 and 3 are fixed to the vehicles by screws. They can by example be fixed on the bodies of vehicles.

Dans le mode de réalisation représenté sur la figure 3, chacune des palettes fixes 2, 3, comprend une partie 18 de surface rugueuse et une partie 19 de surface lisse.In the embodiment shown in Figure 3, each of the pallets fixed 2, 3, includes a part 18 of rough surface and a part 19 of smooth surface.

Les dimensions de la partie lisse 19, issues des calculs de débattement cinématique, sont suffisantes pour que les patins 15 ne reposent pas sur la partie rugueuse 18 quelques soient les positions relatives des palettes fixes 2, 3, et mobile 4.The dimensions of the smooth part 19, derived from the clearance calculations kinematics, are sufficient for the pads 15 not to rest on the rough part 18 whatever the relative positions of the fixed pallets 2, 3, and mobile 4.

Le parallélogramme déformable est alors fixé sur la partie 19, celle-ci étant fixée par visserie sur la partie 18. La partie 19 soumise à l'usure peut être ainsi facilement changée.The deformable parallelogram is then fixed on the part 19, the latter being fixed by screws on part 18. Part 19 subject to wear can be thus easily changed.

La partie 18 est alors fixée sur la caisse du véhicule.Part 18 is then fixed to the body of the vehicle.

Ce mode de réalisation permet d'adapter facilement le plancher à différents types de véhicules en adaptant les dimensions de la partie 18 des palettes fixes.This embodiment allows the floor to be easily adapted to different types of vehicles by adapting the dimensions of part 18 of the fixed pallets.

Le plancher peut ainsi être aisément démonté et remonté, sur différents véhicules.The floor can thus be easily disassembled and reassembled, on different vehicles.

Le fonctionnement du plancher selon l'invention est maintenant décrit en détail en référence à la figure 3.The operation of the floor according to the invention is now described in detail. with reference to Figure 3.

On définit, pour chaque parallélogramme 5, un angle α formé par les bielles 6 entre elles et un angle β formé par les biellettes 7 entre elles.We define, for each parallelogram 5, an angle α formed by the connecting rods 6 between them and an angle β formed by the links 7 between them.

Les bords transversaux 20 des palettes 2, 3 (ou des parties 18), opposés aux bords transversaux fixés au véhicule, forment entre eux un angle γ.The transverse edges 20 of the pallets 2, 3 (or parts 18), opposite the transverse edges fixed to the vehicle, form an angle γ between them.

Lors du franchissement d'une courbe, tel qu'un virage à droite représenté sur la figure 3, les points d'articulation 12 du parallélogramme 5 proche du centre de courbure se rapprochent l'un de l'autre. Ce rapprochement provoque une diminution des angles α et β.When crossing a curve, such as a right turn shown on the FIG. 3, the articulation points 12 of the parallelogram 5 close to the center of curvature are approaching each other. This reconciliation causes a decrease of the angles α and β.

Au contraire, les points d'articulation 12 du parallélogramme 5 distant du centre de courbure s'éloignent l'un de l'autre. Cet éloignement provoque une augmentation des angles α et β. On the contrary, the articulation points 12 of the parallelogram 5 distant from the center of curvature move away from each other. This remoteness causes a increased angles α and β.

Lors de ce mouvement, les points d'articulation 9 et 12 de chaque parallélogramme 5 restent alignés, chaque point d'articulation 9 restant équidistant des points d'articulation 12, de sorte qu'en sortie du virage, les palettes fixes 2, 3 et mobile 4 vont se positionner d'elles mêmes les unes par rapport aux autres de manière que l'axe médian X de la palette 4 s'aligne avec la bissectrice de l'angle γ, sans nécessiter l'intervention d'un moyen de rappel, tel qu'un ressort.During this movement, the articulation points 9 and 12 of each parallelogram 5 remain aligned, each articulation point 9 remaining equidistant from the articulation points 12, so that at the end of the turn, the fixed pallets 2, 3 and mobile 4 will position themselves one by one relation to others so that the median axis X of pallet 4 aligns with the bisector of the angle γ, without requiring the intervention of a return means, such as a spring.

L'axe de l'articulation 13 étant parallèle au plan du plancher, l'extrémité du bras 11 reliée à une articulation 12 peut se déplacer suivant une direction perpendiculaire au plan du plancher. Cette articulation particulière permet de rattraper les différences de niveau pouvant se former entre les différentes palettes.The axis of the joint 13 being parallel to the plane of the floor, the end of the arm 11 connected to a joint 12 can move in a direction perpendicular to the plane of the floor. This particular articulation allows make up for the differences in level that may form between the different pallets.

Les éventuels mouvements de roulis sont quant à eux supportés par la palette mobile 4 grâce à une certaine souplesse en flexion de cette dernière.Any roll movements are supported by the pallet mobile 4 thanks to a certain flexibility in bending of the latter.

Le roulis peut être repris au droit des parallélogrammes déformables, par exemple par un silent bloc au niveau des articulations 12 ou 13.Roll can be resumed at the right of the deformable parallelograms, by example by a silent block at the joints 12 or 13.
