Description

La présente invention concerne un bogie moteur de véhicule ferroviaire, du type comprenant au moins une paire de roues, les roues de la ou chaque paire étant reliées l'une à l'autre par un arbre pour former un essieu, le bogie comprenant en outre un moteur pour entraîner l'essieu en rotation autour de son axe.The present invention relates to a railway vehicle engine bogie, of the type comprising at least one pair of wheels, the wheels of the or each pair being connected to each other by a shaft to form an axle, the bogie further comprising a motor for driving the axle in rotation about its axis.

L'invention concerne également un véhicule ferroviaire comprenant un tel bogie.The invention also relates to a railway vehicle comprising such a bogie.

Dans un véhicule ferroviaire, chaque bogie motorisé, ou bogie moteur, comprend généralement deux paires de roues, les roues d'une paire étant reliées l'une à l'autre par un arbre pour former un essieu, un châssis reliant lesdits essieux l'un à l'autre, des suspensions interposées chacune entre un demi-châssis et un essieu, ladite suspension permettant un déplacement vertical relatif de l'essieu par rapport au demi-châssis correspondant, et des moyens d'entraînement en rotation de l'un des essieux ou de chaque essieu. Ces moyens d'entraînement comprennent au moins un moteur et une chaîne cinématique assurant la transmission du couple moteur du moteur à l'essieu, ainsi que la transmission du couple de freinage de l'essieu au moteur. Les moyens d'entraînement se différencient par la répartition de leurs masses qui sont soit « non suspendues », c'est-à-dire liées à l'essieu, soit « suspendues », c'est-à-dire liées au châssis de bogie au dessus des suspensions. Ces moyens d'entraînement se différencient par leur facilité d'intégration dans le bogie en terme d'encombrement, que ce soit en largeur (c'est-à-dire parallèlement à l'axe de l'essieu) ou en longueur (parallèlement au sens de marche du véhicule). Ils se différencient en complexité par le nombre de pièces qu'ils comprennent.In a railway vehicle, each motorized bogie, or motor bogie, generally comprises two pairs of wheels, the wheels of a pair being connected to each other by a shaft to form an axle, a chassis connecting said axles one to the other, suspensions interposed each between a half-frame and an axle, said suspension allowing a relative vertical displacement of the axle relative to the corresponding half-frame, and means for driving in rotation of the one axles or each axle. These drive means comprise at least one motor and a kinematic chain ensuring the transmission of engine torque from the engine to the axle, as well as the transmission of the braking torque from the axle to the engine. The drive means are differentiated by the distribution of their masses which are either "not suspended", that is to say related to the axle, or "suspended", that is to say related to the chassis of bogie above the suspensions. These drive means differ in their ease of integration into the bogie in terms of size, whether in width (that is to say parallel to the axis of the axle) or in length (parallel in the direction of travel of the vehicle). They differ in complexity by the number of pieces they understand.

Pour réduire les efforts verticaux dans la voie, il est avantageux de diminuer les masses non suspendues. Pour faciliter l'intégration des moyens d'entraînement, il est avantageux de diminuer les encombrements.To reduce the vertical forces in the track, it is advantageous to reduce the unsprung masses. To facilitate the integration of the drive means, it is advantageous to reduce congestion.

On connaît de EP 1 320 478 un bogie de véhicule ferroviaire dans lequel le moteur est monté entre les roues de l'essieu, le rotor du moteur étant solidaire de l'essieu et le stator étant monté sur l'essieu par l'intermédiaire de paliers, de sorte que le moteur est non suspendu. Une bielle de réaction articulée au stator et au châssis de bogie permet de reprendre les couples et d'assurer les débattements dus aux mouvements entre le châssis de bogie et l'essieu. Les moyens d'entraînement sont ainsi particulièrement compacts. Ils présentent cependant l'inconvénient d'avoir des masses non suspendues élevées, ce qui limite la vitesse du véhicule. En outre, à voie et diamètre de roue constants, il est très difficile d'augmenter le couple moteur exercé sur l'essieu.We know EP 1,320,478 a railway vehicle bogie in which the engine is mounted between the wheels of the axle, the rotor of the motor being secured to the axle and the stator being mounted on the axle by means of bearings, so that the motor is not suspended. A reaction link articulated to the stator and to the bogie frame makes it possible to recover the torques and to ensure the movements due to the movements between the bogie frame and the axle. The drive means are thus particularly compact. However, they have the disadvantage of having unsprung masses high, which limits the speed of the vehicle. In addition, constant track and wheel diameter, it is very difficult to increase the engine torque exerted on the axle.

On connaît de WO 2006/051046 un bogie de véhicule ferroviaire dans lequel le moteur est monté suspendu entre les roues de l'essieu, le rotor formant un arbre creux sensiblement coaxial à l'essieu. Pour compenser les débattements dus aux mouvements entre le châssis de bogie et l'essieu, des organes d'accouplement tolérant un léger désaxement du rotor relativement à l'axe de l'essieu, disposés aux extrémités axiales du rotor, assurent la transmission de couple entre le rotor et l'essieu. Les masses non suspendues sont ainsi réduites. Toutefois, cette transmission augmente l'encombrement du bogie dans le sens de marche du véhicule. En outre, le moteur dispose de moins d'espace entre les roues, de sorte que la longueur de fer, et donc le couple exercé sur l'essieu, sont plus faibles que dans la solution décrite dans EP 1 320 478 .We know WO 2006/051046 a railway vehicle bogie in which the motor is suspended between the wheels of the axle, the rotor forming a hollow shaft substantially coaxial with the axle. To compensate for the movements due to the movements between the bogie frame and the axle, coupling members that tolerate slight misalignment of the rotor relative to the axis of the axle, arranged at the axial ends of the rotor, ensure the transmission of torque. between the rotor and the axle. The unsprung masses are thus reduced. However, this transmission increases the size of the bogie in the direction of travel of the vehicle. In addition, the engine has less space between the wheels, so that the length of iron, and therefore the torque exerted on the axle, are lower than in the solution described in EP 1,320,478 .

On connaît par ailleurs des véhicules ferroviaires comprenant des couloirs bas larges. De tels véhicules sont généralement appelés « véhicules à plancher bas ». Pour ces véhicules, il est nécessaire de concevoir des bogies spécifiques de façon à ce que le couloir central bas puisse s'étendre sur toute la longueur du véhicule, sans marche, tout en passant au-dessus des bogies. A cet effet, l'espace central du bogie, s'étendant longitudinalement entre les roues, doit être le plus dégagé possible.Rail vehicles are also known comprising wide bottom corridors. Such vehicles are generally called "low floor vehicles". For these vehicles, it is necessary to design specific bogies so that the low central corridor can extend over the entire length of the vehicle, without walking, while passing over the bogies. For this purpose, the central space of the bogie, extending longitudinally between the wheels, must be as clear as possible.

Les bogies décrits dans EP 1 320 478 et WO 2006/051046 ne conviennent pas à ce type de véhicules.The bogies described in EP 1,320,478 and WO 2006/051046 not suitable for this type of vehicle.

EP 2 142 411 décrit un bogie spécialement conçu pour un véhicule à plancher bas, permettant l'aménagement d'un couloir central bas large dans le châssis de la caisse, de façon à permettre un accès sans marche à tout le véhicule. Cet objectif est atteint notamment grâce à une disposition spécifique du moteur, qui est disposé le long d'un bord extérieur du bogie, en étant orienté parallèlement au sens de marche du véhicule. Si cette disposition permet de dégager efficacement l'espace central, elle présente l'inconvénient de nécessiter une surélévation du plancher au-dessus de l'espace occupé par le moteur, ce qui a pour conséquence de compliquer l'accès à certaines parties du véhicule ferroviaire. EP 2 142 411 describes a bogie specially designed for a vehicle with a low floor, allowing the development of a wide bottom central corridor in the chassis of the body, so as to allow a stepless access to the entire vehicle. This objective is achieved in particular thanks to a specific arrangement of the engine, which is arranged along an outer edge of the bogie, being oriented parallel to the direction of travel of the vehicle. If this arrangement effectively clears the central space, it has the disadvantage of requiring an elevation of the floor above the space occupied by the engine, which has the effect of complicating access to certain parts of the vehicle rail.

Un objectif de l'invention est de proposer un bogie moteur de véhicule ferroviaire permettant d'aménager dans le châssis de la caisse un couloir bas large, sans nécessiter la réalisation de marches importantes dans le plancher du véhicule ferroviaire pour passer au-dessus du bogie. D'autres objectifs sont que le bogie moteur intègre des moyens d'entraînement de l'essieu qui soient à la fois compacts et puissants, que lesdits moyens d'entraînement soient simples à mettre en oeuvre, et que les masses non suspendues soient réduites.An object of the invention is to provide a rail vehicle engine bogie for arranging in the frame of the body a wide bottom aisle, without requiring the realization of important steps in the floor of the railway vehicle to pass over the bogie . Other objectives are that the motor bogie incorporates axle drive means which are both compact and powerful, that said drive means are simple to implement, and that the unsprung masses are reduced.

A cet effet, l'invention a pour objet un bogie moteur du type précité, dans lequel le moteur est sensiblement coaxial à l'essieu en étant disposé à l'extérieur du bogie relativement aux roues.To this end, the invention relates to a motor bogie of the aforementioned type, wherein the motor is substantially coaxial with the axle being disposed outside the bogie relative to the wheels.

Dans la suite, les termes « vertical » et « horizontal » sont définis par rapport à un bogie monté dans un véhicule ferroviaire. Ainsi, un plan horizontal est sensiblement parallèle au plan dans lequel s'étendent les essieux et le plan vertical est sensiblement parallèle au plan dans lequel s'étendent les roues. Le terme « longitudinal » est défini par rapport à la direction dans laquelle s'étend un véhicule ferroviaire dans un plan horizontal et le terme « transversal » est défini selon une direction sensiblement perpendiculaire à la direction longitudinale dans un plan horizontal.In the following, the terms "vertical" and "horizontal" are defined with respect to a bogie mounted in a railway vehicle. Thus, a horizontal plane is substantially parallel to the plane in which the axles extend and the vertical plane is substantially parallel to the plane in which the wheels extend. The term "longitudinal" is defined with respect to the direction in which a railway vehicle extends in a horizontal plane and the term "transverse" is defined in a direction substantially perpendicular to the longitudinal direction in a horizontal plane.

Chacun des bogies moteur 10 représentés sur les Figure 1 et 3, comprend deux paires de roues 20, les roues 20 de chaque paire étant reliées l'une à l'autre par un arbre pour former un essieu 22. Les essieux 22 sont reliés l'un à l'autre par un châssis 24, dit intérieur, comprenant deux demi-châssis solidaires chacun d'un essieu 22 respectif. Par châssis intérieur, on entend que des longerons 26 de chaque demi-châssis s'étendent à l'intérieur du gabarit formé par les roues 20, c'est-à-dire qu'ils sont disposés entre les roues 20.Each of the motor bogies 10 represented on the Figure 1 and 3 , comprises two pairs of wheels 20, the wheels 20 of each pair being connected to each other by a shaft to form an axle 22. The axles 22 are connected to one another by a frame 24, said interior, comprising two half-frames each secured to a respective axle 22.

Une suspension primaire 30 est interposée entre chaque longeron 26 et la boîte d'essieu 28 sur laquelle ledit longeron 26 repose. Cette suspension primaire 30 permet entre autre un déplacement vertical relatif de l'essieu 22 par rapport au demi-châssis, c'est-à-dire que le demi-châssis est mobile et suspendu par rapport à l'essieu 22 selon une direction sensiblement verticale.A primary suspension 30 is interposed between each spar 26 and the axle box 28 on which said spar 26 rests. This primary suspension 30 allows inter alia relative vertical displacement of the axle 22 relative to the half-frame, that is to say that the half-frame is movable and suspended relative to the axle 22 in a direction substantially vertical.

Les deux demi-châssis sont maintenus l'un à l'autre de sorte que les essieux 22 restent parallèles et que le bogie 10 ne se replie pas sur lui même sous l'effet d'une charge verticale.The two half-frames are held together so that the axles 22 remain parallel and the bogie 10 does not fold on itself under the effect of a vertical load.

Au moins un des essieux 22, ou les deux essieux 22, est (sont) entraîné(s) en rotation par des moyens d'entraînement comprenant un moteur 34 et une chaîne cinématique assurant la transmission du couple moteur du moteur 34 à l'essieu 22, ainsi que la transmission du couple de freinage de l'essieu 22 au moteur 34. Cette chaîne cinématique comprend un réducteur 36 et un arbre de transmission 38, pour la transmission de l'entraînement du moteur 34 au réducteur 38.At least one of the axles 22, or both axles 22, are rotated by drive means comprising a motor 34 and a kinematic chain ensuring the transmission of the engine torque from the motor 34 to the axle. 22, as well as the transmission of the braking torque from the axle 22 to the motor 34. This drive train comprises a gearbox 36 and a transmission shaft 38, for the transmission of the drive from the motor 34 to the gearbox 38.

Le moteur 34 est disposé à l'extérieur du gabarit formé par les roues 20. En d'autres termes, il est disposé transversalement à l'extérieur du bogie 10 relativement aux roues 20.The motor 34 is disposed outside the template formed by the wheels 20. In other words, it is arranged transversely outside the bogie 10 relative to the wheels 20.

Le moteur 34 est également sensiblement coaxial à l'essieu 22, aux débattements autorisés par la suspension 30 près.The motor 34 is also substantially coaxial with the axle 22, at the clearances allowed by the suspension 30 near.

Le moteur 34 comprend un rotor 42 et un stator 44.The motor 34 comprises a rotor 42 and a stator 44.

Le stator 44 est lié au châssis 24 par un premier organe de liaison 46. Cet organe de liaison 46 est adapté pour reprendre les couples entre le stator 44 et le châssis 24.The stator 44 is connected to the frame 24 by a first connecting member 46. This connecting member 46 is adapted to take up the torques between the stator 44 and the frame 24.

Le rotor 42 est coaxial au stator 44. Des paliers 48 assurent la liaison du rotor 42 au stator 44, tout en permettant la rotation du rotor 42 autour de son axe relativement au stator 44.The rotor 42 is coaxial with the stator 44. Bearings 48 connect the rotor 42 to the stator 44, while allowing the rotor 42 to rotate about its axis relative to the stator 44.

Le rotor 42 est solidaire en rotation de l'arbre 38.The rotor 42 is integral in rotation with the shaft 38.

Le stator 44 est monté autour du rotor 42, de sorte que le moteur 34 forme un moteur à rotor interne.The stator 44 is mounted around the rotor 42, so that the motor 34 forms an internal rotor motor.

Le réducteur 36 est sensiblement coaxial à l'essieu 22.The gearbox 36 is substantially coaxial with the axle 22.

Le réducteur 36 est également disposé à l'extérieur du gabarit formé par les roues 20. Il est en particulier disposé à une extrémité axiale opposée de l'essieu 22 relativement au moteur 34, de sorte que le moteur 34 et le réducteur 36, ensemble, encadrent transversalement l'essieu 22.The gearbox 36 is also disposed outside the jig formed by the wheels 20. It is in particular arranged at an opposite axial end of the axle 22 relative to the motor 34, so that the motor 34 and the gearbox 36, together transversely frame the axle 22.

Le réducteur 36 est un réducteur à train épicycloïdal. Il comprend de façon connue une pluralité d'éléments d'engrènement 50, 52, 54, 56, dont un planétaire intérieur 50 formant un pignon d'entrée du réducteur 36, sensiblement coaxial à l'essieu 22, une couronne 52 coaxiale au planétaire intérieur 50, une pluralité de satellites 54 interposés entre le planétaire intérieur 50 et la couronne 52, chacun étant engrené sur le planétaire intérieur 50 et la couronne 52, et un porte-satellites 56, coaxial au planétaire intérieur 50 et à la couronne 52, sur lequel chaque satellite 54 est monté rotatif autour de son axe.The gearbox 36 is an epicyclic gearbox. It comprises in known manner a plurality of meshing elements 50, 52, 54, 56, including an inner sun gear 50 forming an input gear of the gearbox 36, substantially coaxial with the axle 22, a ring 52 coaxial to the sun gear. inside 50, a plurality of satellites 54 interposed between the inner sun gear 50 and the ring gear 52, each geared to the inner sun gear 50 and the ring gear 52, and a planet carrier 56, coaxial with the inner sun gear 50 and the ring gear 52, on which each satellite 54 is rotatably mounted about its axis.

Le planétaire intérieur 50 est solidaire en rotation de l'arbre 38. La couronne 52 est liée au châssis 24 par un deuxième organe de liaison 58 adapté pour reprendre les couples entre la couronne 52 et le châssis 24. Le porte-satellites 56 est solidaire de l'essieu 22, en particulier de l'une des roues 20 de l'essieu 22.The inner sun gear 50 is integral in rotation with the shaft 38. The ring gear 52 is connected to the frame 24 by a second connecting member 58 adapted to take up the torques between the ring gear 52 and the frame 24. The planet carrier 56 is secured to of the axle 22, in particular of one of the wheels 20 of the axle 22.

Le deuxième organe de liaison 58 est de préférence une bielle autorisant les débattements dus aux mouvements entre le châssis 24 et l'essieu 22. Le réducteur 36 est ainsi semi-suspendu.The second connecting member 58 is preferably a connecting rod allowing movement due to movements between the frame 24 and the axle 22. The gear 36 is thus semi-suspended.

Selon l'invention, l'essieu 22 est creux et définit une cavité tubulaire axiale interne 60 débouchant à deux extrémités axiales 62, 64 de l'essieu 22. L'arbre 38 s'étend dans ladite cavité 60, de l'une à l'autre des extrémités axiales 62, 64. L'arbre 38 présente deux tronçons d'accouplement 66, 68 opposées dépassant chacun hors de la cavité 60 à chacune des extrémités axiales 62, 64.According to the invention, the axle 22 is hollow and defines an internal axial tubular cavity 60 opening at two axial ends 62, 64 of the axle 22. The shaft 38 extends into said cavity 60, from one to the other of the axial ends 62, 64. The shaft 38 has two opposite coupling portions 66, 68 each protruding outside the cavity 60 at each of the axial ends 62, 64.

Le rotor 42 définit une première cavité 70 de réception de l'un des tronçons d'accouplement 66, et le planétaire intérieur 50 définit une deuxième cavité 72 de réception de l'autre tronçon d'accouplement 68. De manière plus précise, comme représenté en figure 2, chacun des tronçons d'accouplement 66, 68 présente des nervures 74 faisant chacune saillie radialement depuis une face périphérique du tronçon 66, 68 et étant orientée axialement, lesdites nervures 74 étant réparties sur la périphérie du tronçon 66, 68 et coopérant avec des cannelures complémentaires (non représentées) formées dans les parois dans la cavité 70, 72 dans laquelle il est reçu.The rotor 42 defines a first cavity 70 for receiving one of the coupling sections 66, and the inner sun gear 50 defines a second cavity 72 for receiving the other coupling section 68. More specifically, as shown in figure 2 , each of the coupling sections 66, 68 has ribs 74 each projecting radially from a peripheral face of the section 66, 68 and being oriented axially, said ribs 74 being distributed over the periphery of the section 66, 68 and cooperating with grooves complementary (not shown) formed in the walls in the cavity 70, 72 in which it is received.

L'arbre 38 est sensiblement coaxial à l'essieu 22, c'est-à-dire que l'axe de l'arbre 38 intersecte l'axe de l'essieu 22, l'angle entre les deux axes étant toujours, en valeur absolue, inférieur à 1°.The shaft 38 is substantially coaxial with the axle 22, that is to say that the axis of the shaft 38 intersects the axis of the axle 22, the angle between the two axes being always, in absolute value, less than 1 °.

Le bogie 10 comprend également un dispositif de freinage de l'essieu 22, adapté pour exercer un couple résistant sur l'essieu 22 de façon à l'immobiliser en rotation relativement au châssis 24. De façon connue, ce dispositif de freinage comprend un disque de frein 76 et un étrier (non représenté), l'étrier étant solidaire en translation suivant la direction longitudinale du châssis 24 ou du réducteur 36, et étant adapté pour pincer le disque de frein 76 de façon à empêcher tout déplacement du disque de frein 76 relativement à l'étrier.The bogie 10 also comprises a braking device of the axle 22, adapted to exert a resistant torque on the axle 22 so as to immobilize it in rotation relative to the frame 24. In known manner, this braking device comprises a disk brake 76 and a caliper (not shown), the yoke being integral in translation in the longitudinal direction of the frame 24 or the gearbox 36, and being adapted to clamp the brake disc 76 so as to prevent any displacement of the brake disc 76 relative to the stirrup.

Dans l'exemple représenté, le réducteur 36 est interposé entre le disque de frein 76 et une roue 20 de l'essieu 22. Le disque de frein 76 est en particulier solidaire du planétaire intérieur 50.In the example shown, the gearbox 36 is interposed between the brake disc 76 and a wheel 20 of the axle 22. The brake disc 76 is in particular integral with the inner sun gear 50.

Dans le mode de réalisation de la Figure 1, le moteur 34 est suspendu. A cet effet, le premier organe de liaison 46 est un organe de liaison rigide, adapté pour lier rigidement le moteur 34 au châssis 24.In the embodiment of the Figure 1 the motor 34 is suspended. For this purpose, the first connecting member 46 is a rigid connecting member adapted to rigidly connect the motor 34 to the frame 24.

Les tronçons d'accouplement 66, 68, sont par ailleurs adaptés pour permettre une inclinaison de l'axe de l'arbre de transmission 38 relativement à l'axe du rotor 42 et relativement à l'axe du réducteur 36. A cet effet, comme visible sur la Figure 2, chaque nervure 74 comprend un bord libre 78 sensiblement bombé, c'est-à-dire que le bord libre 78 de la nervure 74, qui constitue le bord de la nervure 74 le plus éloigné radialement de l'axe de l'arbre 38, a une forme approximativement d'arc de cercle.The coupling sections 66, 68 are moreover adapted to allow an inclination of the axis of the transmission shaft 38 relative to the axis of the rotor 42 and relative to the axis of the gearbox 36. For this purpose, as visible on the Figure 2 each rib 74 comprises a free-convex edge 78 that is to say that the free edge 78 of the rib 74, which constitutes the edge of the rib 74 furthest radially from the axis of the shaft 38, has an approximately circular arc shape.

Les tronçons d'accouplement 66, 68 forment ainsi, avec les cavités 70, 72 dans lesquelles ils sont reçus, des joints de transmission. Ce type de joints de transmission est particulièrement avantageux car il est simple à réaliser. En variante, d'autres joints de transmission sont utilisés pour accoupler l'arbre 38 au rotor 42 du moteur 34 et au planétaire intérieur 50 du réducteur 36.The coupling sections 66, 68 thus form, with the cavities 70, 72 in which they are received, transmission joints. This type of transmission joints is particularly advantageous because it is simple to perform. Alternatively, other transmission joints are used to couple the shaft 38 to the rotor 42 of the motor 34 and to the inner sun gear 50 of the gearbox 36.

On notera que par « joint de transmission », on comprend un système mécanique permettant l'entraînement mutuel de deux pièces tournantes dont les axes de rotation occupent des positions relatives variables pendant leur fonctionnement.Note that "transmission joint" includes a mechanical system for the mutual drive of two rotating parts whose axes of rotation occupy variable relative positions during operation.

Le diamètre extérieur de l'arbre 38 est alors compris entre 35 et 45 mm, de préférence sensiblement égal à 40 mm, et le diamètre la cavité tubulaire 60 est compris entre 85 et 95 mm, de préférence sensiblement égal à 90 mm.The outer diameter of the shaft 38 is then between 35 and 45 mm, preferably substantially equal to 40 mm, and the diameter of the tubular cavity 60 is between 85 and 95 mm, preferably substantially equal to 90 mm.

En fonctionnement, le rotor 42 entraîne l'arbre de transmission 38 en rotation autour de son axe. Cette rotation est transmise, par l'intermédiaire du deuxième tronçon d'accouplement 68, au planétaire intérieur 50 du réducteur 36. Le planétaire intérieur 50 entraîne à son tour les satellites 54 qui roulent sur la couronne 52. Ce faisant, les satellites 54 entraînent la rotation du porte-satellites 56 autour de son axe et, de ce fait, la rotation de l'essieu 22.In operation, the rotor 42 drives the transmission shaft 38 in rotation about its axis. This rotation is transmitted, through the second coupling section 68, to the inner sun gear 50 of the gearbox 36. The inner sun gear 50 in turn drives the satellites 54 which roll on the ring 52. In doing so, the satellites 54 drive the rotation of the planet carrier 56 about its axis and, as a result, the rotation of the axle 22.

En cas de déplacement vertical de l'essieu 22 relativement au châssis 24, l'axe du moteur 34 reste fixe par rapport au châssis 24, alors que l'axe du réducteur 36 suit le déplacement de l'essieu 22. Il s'ensuit un déplacement relatif des axes du moteur 34 et du réducteur 36, qui, s'ils restent parallèles l'un à l'autre, ne sont alors plus alignés. De ce fait, l'arbre de transmission 38 s'incline relativement à la direction des axes du moteur 34 et du réducteur 36, cette inclinaison étant permise grâce à l'accouplement de l'arbre 38 au moteur 34 et au réducteur 36 par l'intermédiaire de joints de transmission.In case of vertical displacement of the axle 22 relative to the frame 24, the axis of the motor 34 remains fixed relative to the frame 24, while the axis of the gearbox 36 follows the displacement of the axle 22. It follows a relative displacement of the axes of the motor 34 and the gearbox 36, which, if they remain parallel to one another, are then no longer aligned. As a result, the transmission shaft 38 inclines relative to the direction of the axes of the motor 34 and the gearbox 36, this inclination being permitted thanks to the coupling of the shaft 38 to the motor 34 and to the gearbox 36 by intermediate transmission seals.

Ce mode de réalisation permet de limiter les masses non suspendues.This embodiment makes it possible to limit the unsprung masses.

Dans le mode de réalisation de la Figure 3, le moteur 34 est semi-suspendu. A cet effet, le premier organe de liaison 46 est une bielle autorisant les débattements dus aux mouvements entre le châssis 24 et l'essieu 22. En outre, l'essieu 22 comprend un tronçon extérieur 80 dépassant à l'extérieur du gabarit formé par les roues 20, le rotor 42 définissant une cavité cylindrique 82 de réception dudit tronçon extérieur 80 et étant monté sur ledit tronçon 80 par l'intermédiaire de paliers 84.In the embodiment of the Figure 3 the motor 34 is semi-suspended. For this purpose, the first connecting member 46 is a connecting rod allowing movements due to movements between the frame 24 and the axle 22. In addition, the axle 22 comprises an outer portion 80 projecting outside the template formed by the wheels 20, the rotor 42 defining a cylindrical cavity 82 for receiving said outer portion 80 and being mounted on said section 80 via bearings 84.

En fonctionnement, le rotor 42 entraîne l'arbre de transmission 38 en rotation autour de son axe. Cette rotation est transmise, par l'intermédiaire du deuxième tronçon d'accouplement 68, au planétaire intérieur 50 du réducteur 36. Le planétaire intérieur 50 entraîne à son tour les satellites 54 qui roulent sur la couronne 52. Ce faisant, les satellites 54 entraînent la rotation du porte-satellites 56 autour de son axe et, de ce fait, la rotation de l'essieu 22.In operation, the rotor 42 drives the transmission shaft 38 in rotation about its axis. This rotation is transmitted, via the second coupling section 68, to the inner sun gear 50 of the gearbox 36. The inner sun gear 50 in turn causes the satellites 54 which roll on the ring 52. In doing so, the satellites 54 cause the planet carrier 56 to rotate about its axis and, as a result, the rotation of the axle 22.

En cas de déplacement vertical de l'essieu 22 relativement au châssis 24, les axes du moteur 34 et du réducteur 36 suivent ensemble le déplacement de l'essieu 22. Lesdits axes restent ainsi alignés. Dans ce deuxième mode de réalisation, l'arbre 38 ne s'incline donc pas par rapport à l'essieu 22, de sorte qu'il est possible de réduire le diamètre de la cavité tubulaire 60.In case of vertical displacement of the axle 22 relative to the frame 24, the axes of the motor 34 and the gearbox 36 together follow the displacement of the axle 22. Said axes thus remain aligned. In this second embodiment, the shaft 38 does not incline with respect to the axle 22, so that it is possible to reduce the diameter of the tubular cavity 60.

Grâce à l'invention décrite ci-dessus, il est possible d'aménager dans le châssis de la caisse du véhicule ferroviaire auquel est intégré le bogie 10 un couloir bas large, sans nécessiter la réalisation de marches importantes dans le plancher dudit véhicule ferroviaire.Thanks to the invention described above, it is possible to arrange in the frame of the body of the railway vehicle which is integrated in the bogie 10 a wide low aisle, without requiring the realization of significant steps in the floor of said railway vehicle.
