Definitions
- the invention relates to a bogie for railway vehicles with spacing wheels variable and more particularly to a bogie comprising a chassis carrying 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 ability to quickly adjust bogie wheel spacing to different width track existing between certain rail networks.

- Such bogie has the disadvantage of not being suitable for receiving traction motors. So, if it is possible with such a bogie to modify the spacing wheels of towed vehicles, it is however necessary to change the drive advantage of a power train adapted to the new gauge of the tracks when a train is preparing to pass on a network having a different track width. Such a change of motor considerably complicates logistics and is not compatible with optimal use of equipment.
- the object of the present invention is therefore to propose a bogie allowing a variable wheel spacing which can, without modification of its structure, be used as a simple carrying bogie or as a driving bogie in order to be able indifferently equip traction vehicles and towed vehicles.

- the first branch 51 comprises a body having a large volume which constitutes a transmission casing in which a gear train 6 ensuring the transmission of the rotational movement between the wheel 4 and a secondary shaft 16 disposed near the hinge axis 3.
- This secondary shaft 16 of each articulated arm 5 opens towards the inside of the frame 12, as shown in Figure 1, and is connected, via a gimbal 7, to an output shaft of a traction motor 8 fixed directly under the vehicle body by silentblocs 19.
- the traction motor 8 can also be fixed directly to the bogie frame 1 and in particular to the central cross member 11.
- 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 motor of traction 8 being centered on the longitudinal axis of the bogie and comprising an output shaft on each of its two sides.
- Each of the output shafts of the traction motor 8 has a cooperating disc 9 with a brake caliper 10 fixed directly to the central cross member 11 of the chassis 1, or fixed to the structure of the traction motor 8 in the alternative embodiment not shown where the traction motor 8 is fixed directly to the chassis 1, the assembly constituting a disc brake system for braking the output shaft of the traction motor 8 and therefore the wheel 4 which is connected to it via the train gear 6 and gimbal 7.

- locking means are for example described in patent application FR 1 558 329.
- the half-axle comprises a gear wheel 61 belonging to the gear train 6 ensuring the transmission of the movement of rotation of the wheel 4 towards the secondary shaft 16.
- This gear wheel 61 is located in the transmission casing formed by the body of the first branch 51 and accompanies the half-axle in its transverse movement.
- the gear wheel 61 cooperates with a second gear wheel 62, shown schematically in dotted in Figures 1 and 6, which is immobile transversely and has a wider width allowing the drive 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 secured to the shaft secondary 16.
- the bogie thus produced can adapt to two different track widths by operating from 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 track width to another.

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 spacing wheels variable and more particularly to a bogie comprising a chassis carrying 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 ability to quickly adjust bogie wheel spacing to different width track existing between certain rail networks.

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.EP-B1-0 591 088 discloses a carrier bogie for a vehicle rail allowing a variable spacing between the wheels and comprising a chassis central and four swing arms joined to the central chassis, the arms each supporting a set of transversely movable bearings for positioning the wheels of the bogie in two positions corresponding to two different track widths. Such bogie has the disadvantage of not being suitable for receiving traction motors. So, if it is possible with such a bogie to modify the spacing wheels of towed vehicles, it is however necessary to change the drive advantage of a power train adapted to the new gauge of the tracks when a train is preparing to pass on a network having a different track width. Such a change of motor considerably complicates logistics and is not compatible with optimal use of equipment.

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.In FIGS. 1 to 5, the
Conformément aux figures 5 et 7, le demi-essieu comporte une roue d'engrenage 61

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

secondaire 16.In accordance with FIGS. 5 and 7, the half-axle comprises a
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 track widths by operating from 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 track width to another. The wheel spacing change will be achieved by releasing the sets of bogies bearings from their locking means and by moving the train at speed reduced on the installation, the rails and the counter-rails then come to guide the wheels in their transverse displacements. Such a type of installation is for example described in 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 bogie motor by connecting the secondary shaft of the articulated arms to a traction motor, according to the particular embodiment described above, but also to be able to be used as a simple carrying bogie while retaining the same bogie structure and connecting the secondary shaft to a simple device braking consisting for example of a shaft provided with brake discs, the latter being then coupled to the universal joints in a similar manner to what has been described above. In the case where the bogie according to the invention is used as a simple carrying bogie, the shaft supporting the brake discs will for example be guided by one or more bearings which will advantageously be directly connected to the chassis and in particular to the central crosspiece.
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 motorization distributed on each of the bogies, this distribution motorization with the advantage of better weight distribution and allow more passengers to board thanks to the transport of passengers on all the vehicles making up 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 in no way limited to the embodiment described and illustrated which has been given only as an example. Modifications are still possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without however leaving the field 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 bogie with spacing wheels variable according to the invention may be equipped with a traction motor per wheel. In in such a case, the motor could advantageously be fixed directly to the articulated arm, the motor output shaft then being connected directly to the secondary shaft of the articulated arm.
