Description

L'invention se rapporte à un bogie pour véhicules ferroviaires à roues à écartement variable et plus particulièrement à un bogie comportant un châssis porteur de la caisse du véhicule et quatre roues reliées au châssis par des bras articulés, chaque roue étant déplaçable transversalement par rapport à son bras support de manière à pouvoir adapter rapidement l'écartement des roues du bogie à la différence de largeur de voie existant entre certains réseaux ferroviaires.The invention relates to a bogie for railway vehicles with variable gauge wheels and more particularly to a bogie comprising a chassis supporting the vehicle body and four wheels connected to the chassis by articulated arms, each wheel being movable transversely relative to its support arm so as to quickly adapt the wheel spacing of the bogie to the difference in track width existing between some rail networks.

Il est connu, du document EP-B1-0 591 088 , un bogie porteur pour véhicule ferroviaire permettant un écartement variable entre les roues et comportant un châssis central et quatre bras oscillant joints au châssis central, les bras supportant chacun un ensemble de roulements mobile transversalement permettant de placer les roues du bogie dans deux positions correspondant à deux largeurs de voie différentes. Un tel bogie présente cependant l'inconvénient de ne pas être adapté pour recevoir des moteurs de traction. Ainsi, s'il est possible avec un tel bogie de modifier l'écartement des roues des véhicules tractés, il est toutefois nécessaire de changer de motrice au profit d'une motrice adaptée au nouvel écartement des voies lorsqu'un train s'apprête à passer sur un réseau possédant une largeur de voie différente. Un tel changement de motrice complique considérablement la logistique et n'est pas compatible avec l'exploitation optimale du matériel.It is known from the document EP-B1-0 591 088 a bogie carrier for a railway vehicle allowing a variable spacing between the wheels and comprising a central frame and four oscillating arms joined to the central frame, the arms each supporting a set of transversely movable bearings for placing the wheels of the bogie in two positions corresponding to two different lane widths. Such a bogie however has the disadvantage of not being adapted to receive traction motors. Thus, if it is possible with such a bogie to change the wheel spacing of towed vehicles, it is however necessary to change the motor to the benefit of a motor adapted to the new gauge of the tracks when a train is preparing to switch to a network with a different lane width. Such a change of power greatly complicates the logistics and is not compatible with the optimal exploitation of the equipment.

Le but de la présente invention est donc de proposer un bogie permettant un écartement variable des roues qui puisse, sans modification de sa structure, être utilisé comme un simple bogie porteur ou comme un bogie moteur afin de pouvoir indifféremment équiper des véhicules de traction et des véhicules tractés.The object of the present invention is therefore to provide a bogie allowing a variable spacing of the wheels which can, without modification of its structure, be used as a simple bogie carrier or as a motor bogie so that it can indifferently equip traction vehicles and towed vehicles.

Un autre but de l'invention est également de proposer un bogie permettant un écartement variable des roues qui soit adapté pour équiper les véhicules ferroviaires circulant à grande vitesse (supérieure à 300 km/h) et notamment les nouveaux véhicules possédant une motorisation répartie sur l'ensemble des bogies du véhicule.Another object of the invention is also to propose a bogie allowing a variable spacing of the wheels which is adapted to equip rail vehicles traveling at high speed (greater than 300 km / h) and in particular the new vehicles having a motorization distributed on the road. set of bogies of the vehicle.

Les figures 1 et 2 représentent un bogie à quatre roues 4 pour véhicule ferroviaire comportant un châssis 1 porteur de la caisse du véhicule constitué d'une traverse centrale 11 reliée par ses extrémités à un cadre 12 rectangulaire délimitant le pourtour du châssis 1 du bogie, le cadre 12 étant formé par deux longerons longitudinaux et deux barres transversales. Les liaisons entre les roues 4 et le châssis 1 sont réalisées par quatre bras articulés 5 s'étendant sous le châssis 1, ces quatre bras 5 comportant chacun une première 51 et une seconde branche 52 reliées entre elles par une traverse 53, l'ensemble première branche 51, seconde branche 52 et traverse 53 formant une fourche ouverte vers l'extérieur s'étendant longitudinalement au bogie dans laquelle est interposée une roue 4.The figures 1 and 2 represent a four-wheeled bogie 4 for a rail vehicle comprising a frame 1 carrying the vehicle body consisting of a central cross member 11 connected at its ends to a rectangular frame 12 delimiting the periphery of the frame 1 of the bogie, the frame 12 being formed by two longitudinal longitudinal members and two transverse bars. The links between the wheels 4 and the chassis 1 are made by four articulated arms 5 extending under the frame 1, these four arms 5 each having a first 51 and a second leg 52 interconnected by a cross member 53, the assembly first leg 51, second leg 52 and crosspiece 53 forming an open fork extending outwardly extending longitudinally to the bogie in which is interposed a wheel 4.

Conformément aux figures 3 et 4, chaque première branche 51 s'étend dans le prolongement vertical d'un des longerons longitudinaux du cadre 12 et comporte une extrémité articulée sur le châssis 1 au moyen d'un palier 2 recevant un axe d'articulation 3 solidaire du cadre 12 et disposé à proximité de la traverse centrale 11. Les premières branches 51 s'étendent depuis leur axe d'articulation 3 jusqu'à l'extrémité longitudinale du châssis 1, l'extrémité libre des premières branches 51 supportant, sur leur face supérieure, un ressort hélicoïdal 13 sur lequel repose le cadre 12.In accordance with Figures 3 and 4 , each first branch 51 extends in the vertical extension of one of the longitudinal longitudinal members of the frame 12 and has an end hinged to the frame 1 by means of a bearing 2 receiving a hinge pin 3 integral with the frame 12 and disposed close to the central cross member 11. The first branches 51 extend from their hinge axis 3 to the longitudinal end of the frame 1, the free end of the first branches 51 supporting, on their upper face, a spring helical 13 on which the frame 12 rests.

La seconde branche 52 des bras articulés 5 est plus courte et moins volumineuse que la première branche 51 et s'étend parallèlement à la première branche 51, en étant disposée à l'intérieur du bogie, depuis la traverse 53 jusqu'à proximité de l'extrémité longitudinale du châssis 1. L'extrémité libre des secondes branches 52 supporte également un ressort hélicoïdal 13 sur lequel repose le cadre 12, l'ensemble des ressorts hélicoïdaux 13 des bras articulés 5 constituant des organes de suspension primaire.The second branch 52 of the articulated arms 5 is shorter and less bulky than the first branch 51 and extends parallel to the first branch 51, being disposed inside the bogie, from the cross 53 to the vicinity of the longitudinal end of the frame 1. The free end of the second legs 52 also supports a helical spring 13 on which the frame 12 rests, the set of helical springs 13 of the articulated arms 5 constituting primary suspension members.

Les bras articulés 5 disposés côte-à-côte sur le bogie sont reliés entre eux par une barre entretoise 14 venant se fixer latéralement sur la seconde branche 52 et servant à la fois à augmenter la rigidité structurelle des bras articulés 5 et à garantir un écartement constant entre les deux bras articulés 5.The articulated arms 5 arranged side by side on the bogie are interconnected by a spacer bar 14 which is laterally fixed on the second branch 52 and serves both to increase the structural rigidity of the articulated arms 5 and to guarantee spacing constant between the two articulated arms 5.

Conformément à la figure 3, la première branche 51 comporte un corps présentant un volume important qui constitue un carter de transmission dans lequel est disposé un train d'engrenages 6 assurant la transmission du mouvement de rotation entre la roue 4 et un arbre secondaire 16 disposé à proximité de l'axe d'articulation 3.In accordance with the figure 3 , the first branch 51 comprises a body having a large volume which constitutes a transmission casing in which is disposed a gear train 6 ensuring the transmission of the rotational movement between the wheel 4 and a secondary shaft 16 disposed near the hinge pin 3.

Cet arbre secondaire 16 de chaque bras articulé 5 débouche vers l'intérieur du cadre 12, ainsi que cela est représenté à la figure 1, et est relié, par l'intermédiaire d'un cardan 7, à un arbre de sortie d'un moteur de traction 8 fixé directement sous la caisse du véhicule par des silentblocs 19. Cependant, dans une variante de réalisation non représentée, le moteur de traction 8 peut également être fixé directement au châssis 1 de bogie et notamment à la traverse centrale 11.This secondary shaft 16 of each articulated arm 5 opens towards the inside of the frame 12, as is shown in FIG. figure 1 , and is connected, via a universal joint 7, to an output shaft of a traction motor 8 fixed directly under the body of the vehicle by silentblocs 19. However, in an embodiment variant, not shown, the traction motor 8 can also be fixed directly to the bogie frame 1 and in particular to the central beam 11.

De manière avantageuse, et conformément au mode de réalisation particulier représenté sur les figures, un seul moteur de traction 8 est utilisé pour entraîner les roues 4 des deux bras articulés 5 disposés côte-à-côte sur le bogie, le moteur de traction 8 étant centré sur l'axe longitudinal du bogie et comportant un arbre de sortie sur chacun de ses deux côtés.Advantageously, and in accordance with the particular embodiment shown in the figures, a single traction motor 8 is used to drive the wheels 4 of the two articulated arms 5 arranged side-by-side on the bogie, the traction motor 8 being centered on the longitudinal axis of the bogie and having an output shaft on each of its two sides.

Chacun des arbres de sortie du moteur de traction 8 comporte un disque 9 coopérant avec un étrier de freinage 10 fixé directement à la traverse centrale 11 du châssis 1, ou fixé à la structure du moteur de traction 8 dans la variante de réalisation non représentée où le moteur de traction 8 est fixé directement au châssis 1, l'ensemble constituant un système de frein à disque permettant de freiner l'arbre de sortie du moteur de traction 8 et donc la roue 4 qui lui est raccordée par l'intermédiaire du train d 'engrenage 6 et du cardan 7.Each of the output shafts of the traction motor 8 comprises a disc 9 cooperating with a brake caliper 10 fixed directly to the central crosspiece 11 of the frame 1, or fixed to the structure of the traction motor 8 in the variant embodiment shown where the traction motor 8 is fixed directly to the frame 1, the assembly constituting a disc brake system for braking the output shaft of the traction motor 8 and thus the wheel 4 connected thereto via of the gear train 6 and the universal joint 7.

Conformément à la figure 2, la face supérieure du cadre 12 du bogie supporte des organes de suspension secondaire 20, représentées en trait mixte sur cette figure, s'interposant entre la caisse et le châssis, l'entraînement et la rotation de la caisse étant assurée par des moyens classiques tels qu'un pivot central d'entraînement, non représenté sur les figures, venant prendre place dans un logement 18 de la traverse centrale 11.In accordance with the figure 2 , the upper face of the frame 12 of the bogie supports secondary suspension members 20, shown in phantom in this figure, interposed between the body and the frame, the drive and the rotation of the body being provided by conventional means such as a central driving pivot, not shown in the figures, coming to take place in a housing 18 of the central beam 11.

La figure 5 représente une section d'un bras articulé 5 au niveau de l'axe de la roue 4. Conformément à cette figure, chaque bras 5 supporte un demi-essieu, solidaire de la roue 4, monté sur deux ensembles de roulements 22 mobiles transversalement à l'intérieur de logements réalisés à l'intérieur de la première 51 et de la seconde branche 52, ces ensembles de roulements 22 mobiles permettant le déplacement du demi-essieu, et donc de la roue 4, dans deux positions correspondant à deux largeurs de voie différentes.The figure 5 represents a section of an articulated arm 5 at the axis of the wheel 4. According to this figure, each arm 5 supports a half-axle, secured to the wheel 4, mounted on two sets of bearings 22 movable transversely to the inside of housings made inside the first 51 and the second branch 52, these sets of movable bearings 22 allowing the displacement of the half-axle, and therefore of the wheel 4, in two positions corresponding to two widths of different way.

Sur les figures 1 à 5, les roues 4 sont représentées dans la position correspondant à la largeur de voie la plus étroite et sur les figures 6 et 7, les roues 4 sont représentées dans la position correspondant à la largeur de voie la plus large. Le blocage des roues 4 dans une position déterminée est réalisé en immobilisant transversalement les ensembles de roulements 22 par des moyens de blocage non représentés sur les figures, tels que des doigts de blocage manipulable par l'extérieur et insérés dans le corps des premières et seconde branches 51 et 52 de manière à constituer des butés bloquant latéralement les ensembles de roulements 22. De tels moyens de blocage sont par exemple décrits dans la demande de brevet FR 1 558 329 .On the Figures 1 to 5 , the wheels 4 are represented in the position corresponding to the narrowest track width and on the figures 6 and 7 the wheels 4 are shown in the position corresponding to the widest track width. The locking of the wheels 4 in a determined position is achieved by immobilizing the bearing assemblies transversely 22 by locking means not shown in the figures, such as locking fingers which can be manipulated by the outside and inserted into the body of the first and second branches 51 and 52 so as to form stops laterally blocking the bearing assemblies 22. Such locking means are for example described in the application of patent FR 1 558 329 .

Conformément aux figures 5 et 7, le demi-essieu comporte une roue d'engrenage 61 appartenant au train d'engrenage 6 assurant la transmission du mouvement de rotation de la roue 4 vers l'arbre secondaire 16. Cette roue d'engrenage 61 est située dans le carter de transmission formé par le corps de la première branche 51 et accompagne le demi-essieu dans son déplacement transversal. La roue d'engrenage 61 coopère avec une deuxième roue d'engrenage 62, représentée schématiquement en pointillé sur les figures 1 et 6, qui est immobile transversalement et possède une largeur plus importante permettant l'engrainement avec la roue d'engrenage 61 dans les deux positions transversales du demi-essieu. La deuxième roue d'engrenage 62 comporte un axe qui est solidaire d'une autre roue d'engrenage 63, cette dernière coopérant avec une roue d'engrenage 64 complémentaire solidaire de l'arbre secondaire 16.In accordance with Figures 5 and 7 , the half-axle comprises a gear wheel 61 belonging to the gear train 6 ensuring the transmission of the rotational movement of the wheel 4 to the secondary shaft 16. This gear wheel 61 is located in the transmission housing formed by the body of the first branch 51 and accompanies the half-axle in its transverse displacement. The gear wheel 61 cooperates with a second gear wheel 62, shown diagrammatically in dotted lines on the figures 1 and 6 , which is immobile transversely and has a greater width allowing the engrainement with the gear wheel 61 in the two transverse positions of the half-axle. The second gear wheel 62 has an axis which is integral with another gear wheel 63, the latter cooperating with a complementary gear wheel 64 integral with the secondary shaft 16.

Le bogie ainsi réalisé peut s'adapter à deux largeurs de voie différentes en opérant de manière connue en soi à l'aide d'une installation fixe munie par exemple de rails et de contre-rails et située au lieu où l'on passe d'une largeur de voie à l'autre. Le changement d'écartement des roues sera ainsi réalisé en libérant les ensembles de roulements des bogies de leurs moyens de blocage et en déplaçant le train à vitesse réduite sur l'installation, les rails et les contre-rails venant alors guider les roues dans leurs déplacements transversaux. Un tel type d'installation est par exemple décrit dans le brevet FR 1 548 462 .The bogie thus produced can adapt to two different lane widths by operating in a manner known per se using a fixed installation provided for example with rails and against rails and located at the place where one passes from one lane width to another. The change in wheel spacing will thus be achieved by releasing the sets of bearings of the bogies from their locking means and by moving the gear at reduced speed on the installation, the rails and the rails against then guiding the wheels in their transversal displacements. Such a type of installation is for example described in the patent FR 1 548 462 .

Le bogie selon l'invention présente l'avantage de pouvoir être utilisé comme un bogie moteur en reliant l'arbre secondaire des bras articulés à un moteur de traction, conformément au mode de réalisation particulier précédemment décrit, mais également de pouvoir être utilisé comme simple bogie porteur en conservant la même structure du bogie et en reliant l'arbre secondaire à un simple dispositif de freinage constitué par exemple d'un arbre muni de disques de freins, ce dernier étant alors accouplé aux cardans de manière similaire à ce qui à été décrit précédemment. Dans le cas où le bogie selon l'invention est utilisé comme un simple bogie porteur, l'arbre supportant les disques de freins sera par exemple guidé par un ou plusieurs paliers qui seront avantageusement reliés directement au châssis et notamment à la traverse centrale.The bogie according to the invention has the advantage of being able to be used as a motor bogie by connecting the secondary shaft of the articulated arms to a traction motor, according to the particular embodiment previously described, but also of being able to be used as simple bogie carrier maintaining the same structure of the bogie and connecting the secondary shaft to a simple braking device consisting for example of a shaft with brake discs, the latter then being coupled to the gimbals in a manner similar to what has been previously described. In the case where the bogie according to the invention is used as a simple bogie carrier, the shaft supporting the brake discs will for example be guided by one or more bearings which will be advantageously connected directly to the frame and in particular to the central cross member.

Un tel bogie présente également l'avantage d'être adapté pour équiper les nouveaux trains à grande vitesse à motorisation répartie sur chacun des bogies, cette répartition de la motorisation présentant l'avantage d'une meilleure répartition des masses et de permettre l'embarquement d'un plus grand nombre de passagers grâce au transport de passagers sur l'ensemble des véhicules constituant le train.Such a bogie also has the advantage of being adapted to equip the new high-speed trains with distributed motorization on each of the bogies, this distribution of the motorization having the advantage of a better distribution of the masses and of allow the boarding of a larger number of passengers by carrying passengers on all vehicles constituting the train.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, dans une variante de réalisation non représenté le bogie à roues à écartement variable selon l'invention pourra être équipé d'un moteur de traction par roue. Dans un tel cas le moteur pourra avantageusement être fixé directement sur le bras articulé, l'arbre de sortie du moteur étant alors connecté directement à l'arbre secondaire du bras articulé.Thus, in an alternative embodiment not shown the variable gauge wheeled bogie according to the invention may be equipped with a wheel traction motor. In such a case the motor can advantageously be fixed directly on the articulated arm, the output shaft of the motor then being directly connected to the secondary shaft of the articulated arm.
