Selon d'autres modes de réalisation, l'ensemble de liaison comprend une ou plusieurs des caractéristiques définies dans les revendications 2 à 5.According to other embodiments, the connection assembly comprises one or more of the characteristics defined in claims 2 to 5.

L'invention concerne également un véhicule ferroviaire comprenant une caisse, un bogie ayant un châssis, et un ensemble de liaison tel que défini ci-dessus, la caisse étant reliée au châssis par l'intermédiaire de l'ensemble de liaison.The invention also relates to a railway vehicle comprising a body, a bogie having a chassis, and a connection assembly as defined above, the body being connected to the chassis via the connection assembly.

L'invention et ses avantages seront mieux compris à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en référence aux dessins annexés, sur lesquels :

  • the figure 1 is a schematic view from below of a connection assembly between a vehicle body and a bogie chassis according to a first unclaimed embodiment of the invention;
  • the figure 2 is a schematic view similar to the figure 1 , of a connection assembly according to a second embodiment of the invention according to claim 1.

L'ensemble de liaison 2 de la figure 1 relie une caisse 4 d'un véhicule 6 à un châssis 8 d'un bogie 10 de ce véhicule 6.Link assembly 2 of the figure 1 connects a body 4 of a vehicle 6 to a chassis 8 of a bogie 10 of this vehicle 6.

La caisse 4 est en appui verticalement sur le châssis 8 par l'intermédiaire de l'ensemble de liaison 2 qui relie la caisse 4 au châssis 8.The body 4 is vertically supported on the chassis 8 by means of the connection assembly 2 which connects the body 4 to the chassis 8.

Le véhicule 6 est un véhicule terrestre guidé, prévu pour se déplacer longitudinalement le long d'une voie en étant guidé transversalement le long de celle-ci par son bogie 10.The vehicle 6 is a guided land vehicle, intended to move longitudinally along a track while being guided transversely along the latter by its bogie 10.

Le véhicule 6 est ici plus particulièrement un véhicule ferroviaire, prévu pour se déplacer le long d'une voie ferrée (non représentée) comprenant deux files de rails parallèles.The vehicle 6 is here more particularly a railway vehicle, intended to move along a railway track (not shown) comprising two parallel rows of rails.

Dans la suite de la description, les termes « longitudinal », « transversal », « vertical », et « horizontal » s'entendent par référence à la direction verticale d'appui de la caisse 4 posée sur le bogie 10 et à la direction longitudinale et horizontale de déplacement du bogie 10 le long de la voie.In the following description, the terms “longitudinal”, “transverse”, “vertical”, and “horizontal” are understood to mean the vertical direction of support of the body 4 placed on the bogie 10 and the direction longitudinal and horizontal movement of the bogie 10 along the track.

Sur la figure 1 est représenté un repère orthogonal correspondant comprenant :

  • un axe vertical Z perpendiculaire au plan de la figure 1.
On the figure 1 a corresponding orthogonal coordinate system is represented comprising:
  • a longitudinal axis X;
  • a transverse axis Y perpendicular to the longitudinal axis X; and
  • a vertical axis Z perpendicular to the plane of the figure 1 .

Le bogie 10 est prévu pour supporter la caisse 4 verticalement et pour la guider transversalement le long de la voie.The bogie 10 is provided to support the body 4 vertically and to guide it transversely along the track.

L'ensemble de liaison 2 est configuré pour soutenir la caisse 4 verticalement par rapport au bogie 10. L'ensemble de liaison 2 est aussi configuré pour lier la caisse longitudinalement et transversalement au bogie 10.The connection assembly 2 is configured to support the body 4 vertically with respect to the bogie 10. The connection assembly 2 is also configured to link the body longitudinally and transversely to the bogie 10.

Le bogie 10 comprend au moins un essieu, ici deux essieux 12, supportant le châssis 8, de préférence par l'intermédiaire d'une suspension primaire (non représentée).The bogie 10 comprises at least one axle, here two axles 12, supporting the chassis 8, preferably by means of a primary suspension (not shown).

Chaque essieu 12 possède une paire de roues 14 coaxiales liées en rotation par un arbre d'essieu 15. L'arbre d'essieu 15 de chaque essieu 12 est ici coaxial aux roues 14, est lié en rotation aux roues 14, chaque roue 14 étant montée sur une extrémité respective de l'arbre d'essieu 15.Each axle 12 has a pair of coaxial wheels 14 linked in rotation by an axle shaft 15. The axle shaft 15 of each axle 12 is here coaxial with the wheels 14, is linked in rotation to the wheels 14, each wheel 14 being mounted on a respective end of the axle shaft 15.

L'ensemble de liaison 2 comprend deux barres de traction 22 et 24 prévues respectivement de part et d'autre du châssis 8. A une extrémité, les barres de traction 22 et 24 sont reliées, par l'intermédiaire d'un organe de liaison rotule 25 et 26, au châssis 8. Par organe de liaison rotule, on entend un dispositif mécanique comprenant au moins deux parties mobiles l'une par rapport à l'autre selon au moins trois axes de rotation orthogonaux. Les organes de liaison rotule 25 et 26 sont de préférence des roulements sphériques à coussin élastomère. A leur autre extrémité, les barres de traction 22 et 24 sont reliées l'une à l'autre par une barre d'équilibrage 28 et s'étendant globalement transversalement par rapport aux barres de traction 22 et 24. La liaison entre les barres de traction 22 et 24 et la barre d'équilibrage 28 est réalisée par deux organes de liaison rotule 29 et 30, formés de préférence par des roulements sphériques à coussin élastomère.The connecting assembly 2 comprises two traction bars 22 and 24 provided respectively on either side of the chassis 8. At one end, the traction bars 22 and 24 are connected, by means of a connecting member ball joint 25 and 26, to the chassis 8. By ball joint member means a mechanical device comprising at least two parts movable relative to each other according to at least three orthogonal axes of rotation. The ball joint connecting members 25 and 26 are preferably spherical bearings with an elastomer cushion. At their other end, the drawbars 22 and 24 are connected to each other by a balancing bar 28 and extending generally transversely with respect to the drawbars 22 and 24. The connection between the bars traction 22 and 24 and the balancing bar 28 is produced by two ball joint members 29 and 30, preferably formed by spherical bearings with an elastomer cushion.

La barre d'équilibrage 28 est reliée à la caisse de véhicule 4 par un organe de liaison pivot 32. Par organe de liaison pivot on entend un dispositif mécanique comprenant au moins deux parties mobiles l'une par rapport à l'autre autour d'un seul axe. L'organe de liaison pivot 32 permet une rotation relative autour de l'axe Z entre la barre d'équilibrage 28 et la caisse de véhicule 4. L'organe de liaison pivot 32 est avantageusement prévu au centre de la barre d'équilibrage 28.The balancing bar 28 is connected to the vehicle body 4 by a pivot link member 32. By pivot link member means a mechanical device comprising at least two parts movable relative to each other around a single axis. The pivot link member 32 allows relative rotation about the Z axis between the balancing bar 28 and the vehicle body 4. The pivot link member 32 is advantageously provided in the center of the balancing bar 28 .

Conformément à l'invention, la barre d'équilibrage 28 et l'organe de liaison pivot 32 sont positionnés en dehors du châssis 8. En d'autres termes, la barre d'équilibrage 28 et l'organe de liaison pivot 32 sont situés en dehors de l'espace délimité par les contours horizontaux du châssis 8.According to the invention, the balancing bar 28 and the pivot connecting member 32 are positioned outside the frame 8. In other words, the balancing bar 28 and the pivot connecting member 32 are located outside the space delimited by the horizontal contours of the chassis 8.

Plus précisément, la barre d'équilibrage 28 et l'organe de liaison pivot 32 sont situés sous la caisse du véhicule 4 en regard d'un bord avant 17 du châssis 8, orienté vers l'avant du véhicule ferroviaire 6 par rapport à sa direction de déplacement.More specifically, the balancing bar 28 and the pivot link member 32 are located under the body of the vehicle 4 opposite a front edge 17 of the chassis 8, facing the front of the rail vehicle 6 relative to its direction of travel.

Cette structure est particulièrement avantageuse dans le cas où la caisse de véhicule 4 est munie d'une poutre de structure centrale 41 sur laquelle la structure de la caisse du véhicule 4 est construite. Ainsi l'organe de liaison pivot 32 peut être directement solidarisé à la poutre centrale 41.This structure is particularly advantageous in the case where the vehicle body 4 is provided with a central structural beam 41 on which the structure of the vehicle body 4 is built. Thus, the pivot connecting member 32 can be directly secured to the central beam 41.

De façon optionnelle, l'ensemble de liaison 2 comprend également une barre d'équilibrage additionnelle 34 reliant les barres de traction 22 et 24 l'une à l'autre à distance de leurs extrémités respectives.Optionally, the connection assembly 2 also includes an additional balancing bar 34 connecting the traction bars 22 and 24 to each other at a distance from their respective ends.

La structure de l'ensemble de liaison 2 selon l'invention permet un gain de place significatif au centre du châssis 8 pour des équipements supplémentaires. Cette structure permet également de prévoir des bogies de dimensions réduites et par conséquent un gain de poids.The structure of the connection assembly 2 according to the invention allows a significant saving of space in the center of the chassis 8 for additional equipment. This structure also makes it possible to provide bogies of reduced dimensions and therefore a saving in weight.

La structure de l'ensemble de liaison 102 permet également d'améliorer les performances de fonctionnement du bogie, notamment en apportant une entrée plus douce en courbe avec une meilleure répartition des forces de guidage, une réduction de l'usure dans les courbes, les lignes droites et les entrées en courbe, une inscription douce dans les courbes serrées, et améliore la stabilité en réduisant la chasse en haute vitesse.The structure of the connection assembly 102 also makes it possible to improve the operating performance of the bogie, in particular by providing a smoother entry into the curve with a better distribution of the guide forces, a reduction in wear in the curves, the straight lines and curved entries, a smooth inscription in tight curves, and improves stability by reducing hunting at high speed.

Un second mode de réalisation est représenté sur la figure 2. Dans ce mode de réalisation, les éléments communs au premier mode de réalisation comportent la même référence augmentée de 100 et fonctionnent de la même manière. Seules les différences par rapport au premier mode de réalisation sont détaillées dans ce qui suit.A second embodiment is shown in the figure 2 . In this embodiment, the elements common to the first embodiment have the same reference increased by 100 and operate in the same way. Only the differences from the first embodiment are detailed in the following.

Dans le second mode de réalisation, l'ensemble de liaison 102 comprend deux organes de liaison pivot 132 et 133 reliant les barres de traction 122 et 124 à la caisse de véhicule 104. Plus précisément, chacune des barres de traction 122 et 124 est reliée aux organes de pivotement 132 et 133 par des pièces mécaniques 140 et 141 articulées sur les organes de liaison pivot 132 et 133 et reliées l'une à l'autre par une barre d'équilibrage 143.

Sur la pièce 141, la barre 141a relie l'organe de liaison rotule 146 à l'organe de liaison pivot 133 et la barre 141b relie l'organe de liaison pivot 133 à l'organe de liaison rotule 148. De préférence, les organes de liaison rotule 145 à 148 sont des roulements sphériques à coussins élastomères.In the second embodiment, the connection assembly 102 comprises two pivot connection members 132 and 133 connecting the traction bars 122 and 124 to the vehicle body 104. More specifically, each of the traction bars 122 and 124 is connected to the pivoting members 132 and 133 by mechanical parts 140 and 141 articulated on the pivot connecting members 132 and 133 and connected to each other by a balancing bar 143. The parts 140 and 141 are parts of triangular shape connected to the drawbars 122 and 124, as well as to the balancing bar 143, by ball joint connecting members 145, 146, 147, and 148. The parts 140 and 141 are formed by three vertices connected by two respective bars 140a, 140b and 141a, 141b. On the part 140, the bar 140a connects the ball joint member 145 to the pivot link member 132 and the bar 140b connects the pivot link member 132 to the ball joint member 147.

Cette structure permet, comme c'est le cas dans le premier mode de réalisation, de libérer une place importante sous le châssis de bogie 110 pour des équipements supplémentaires. Cette structure permet également d'obtenir les avantages de stabilité et de comportement en fonctionnement listés ci-dessus en référence au premier mode de réalisation.This structure allows, as is the case in the first embodiment, to free up an important place under the bogie frame 110 for additional equipment.

Les organes de liaison pivot 132 et 133 sont situés dans le prolongement des bords longitudinaux 108a et 108b du châssis de bogie 108. Les organes de pivotement 132 et 133 sont adaptés pour être solidarisés à deux poutres de structure 150 et 151 latérales longitudinales de la caisse de véhicule 104 sur lesquelles la structure de la caisse 104 est construite.

The pivoting members 132 and 133 are adapted to be secured to two structural beams 150 and 151 longitudinal sides of the vehicle body 104 on which the structure of the body 104 is built. Such a structure is particularly suitable for vehicles made in part of aluminum such as, for example, passenger rail transport cars.

Selon une variante, un amortissement supplémentaire peut être obtenu en utilisant des roulements sphériques à amortissement hydraulique contrôlé sur la base de la fréquence de vibration induite par la vitesse de roulement, au niveau des organes de liaison rotule 25, 26, 29 et 30 pour le premier mode de réalisation de l'invention et 125, 126, 145, 146, 147, 148 pour le second mode de réalisation de l'invention.According to a variant, additional damping can be obtained by using spherical bearings with hydraulic damping controlled on the basis of the vibration frequency induced by the rolling speed, at the level of the ball joint connecting members 25, 26, 29 and 30 for the first embodiment of the invention and 125, 126, 145, 146, 147, 148 for the second embodiment of the invention.

Selon un mode de réalisation non représenté de l'invention, les barres de traction 22 et 24 peuvent être disposées l'une par rapport à l'autre de façon non parallèle, les extrémités des barres de traction 22 et 24 formant dans ce cas un trapèze et non un parallélogramme. Un tel arrangement permet d'accroître les possibilités de rotation autour de l'axe Z-Z' du châssis de bogie par rapport à la caisse de véhicule.According to an embodiment not shown of the invention, the drawbars 22 and 24 can be arranged relative to each other in a non-parallel manner, the ends of the drawbars 22 and 24 in this case forming a trapezoid and not a parallelogram. Such an arrangement makes it possible to increase the possibilities of rotation around the axis Z-Z ′ of the bogie chassis relative to the vehicle body.

Les caractéristiques des modes de réalisation et variantes décrits ci-dessus peuvent être combinées pour former de nouveaux modes de réalisation de l'invention, couverts par les revendications.The features of the embodiments and variants described above can be combined to form new embodiments of the invention, covered by the claims.
