Abstract
Description
La présente invention concerne un bogie à deux essieux orientables, monté pivotant sous une caisse d'un véhicule ferroviaire, comportant un châssis relié à chaque essieu par l'intermédiaire de deux boîtes d'essieux et d'une suspension primaire, deux dispositifs articulés reliant chacun les deux boîtes d'essieux situées d'un même côté du châssis, et un dispositif de commande des deux dispositifs articulés.The present invention relates to a bogie with two orientable axles, pivotally mounted under a body of a railway vehicle, comprising a chassis connected to each axle by means of two axle boxes and a primary suspension, two articulated devices connecting each the two axle boxes located on the same side of the chassis, and a control device for the two articulated devices.
On connait, notamment par la figure 7 du document FR-2.510.962, un tel bogie dont les deux dispositifs articulés sont commandés par la rotation de la caisse autour de l'axe vertical central du bogie. Le dispositif de commande est donc installé sur la couronne de pivotement, entre caisse et châssis, et il comporte deux leviers horizontaux qui agissent sur les deux dispositifs articulés.We know, in particular from FIG. 7 of document FR-2,510,962, such a bogie, the two articulated devices of which are controlled by the rotation of the body around the central vertical axis of the bogie. The control device is therefore installed on the swivel ring, between the body and the chassis, and it comprises two horizontal levers which act on the two articulated devices.
Ce dispositif de commande entièrement mécanique ne permet pas de transmettre des efforts importants pour orienter l'essieu, et on est alors obligé de mettre en place, entre le châssis et les boîtes d'essieux, une suspension primaire à faible raideur.This entirely mechanical control device does not allow significant forces to be transmitted to orient the axle, and it is then necessary to install, between the chassis and the axle boxes, a primary suspension with low stiffness.
Bien que la raideur de la suspension soit faible, la vitesse critique de stabilité en alignement est néanmoins assez élevée car les deux dispositifs articulés assurent un rôle de stabilité.Although the stiffness of the suspension is low, the critical speed of stability in alignment is nevertheless quite high because the two articulated devices provide a role of stability.
Mais, dans le cas d'une défaillance d'un dispositif articulé ou de son dispositif de commande, la faible raideur de la suspension primaire impose une vitesse critique faible.However, in the event of a failure of an articulated device or of its control device, the low stiffness of the primary suspension imposes a low critical speed.
Pour obtenir une vitesse critique importante, donc un bogie stable à grande vitesse, il faut augmenter la raideur de la suspension primaire mais aussi mettre en place un dispositif de commande capable de déformer cette suspension.To obtain a significant critical speed, therefore a stable bogie at high speed, it is necessary to increase the stiffness of the primary suspension but also to install a control device capable of deforming this suspension.
Pour atteindre ce but, la présente invention propose de supprimer les deux leviers de commande horizontaux liés à la couronne de pivotement, et de manoeuvrer les deux dispositifs articulés à l'aide d'au moins un vérin commandé par un ensemble capteur-émetteur d'informations. On a proposé, dans le document SOVIET INVENTIONS ILLUSTRATED, semaine 8742, 28 octobre 1987, classe Q21, n° 87-297330142 et SU-A-1 298 121, de commander la rotation d'un bogie de véhicule, dans son ensemble, au moyen d'un vérin piloté par un capteur de voie.To achieve this aim, the present invention proposes to eliminate the two horizontal control levers linked to the pivoting ring, and to operate the two articulated devices using at least one actuator controlled by a sensor-transmitter assembly. information. We have proposed, in the document SOVIET INVENTIONS ILLUSTRATED, week 8742, October 28, 1987, class Q21, n ° 87-297330142 and SU-A-1 298 121, to control the rotation of a vehicle bogie, as a whole, by means of an actuator controlled by a way.
Cette possibilité d'orientation est insuffisante, surtout lorsque la voie présente un fort rayon de courbure car les essieux du bogie, restent parallèles entre eux.This possibility of orientation is insufficient, especially when the track has a large radius of curvature because the axles of the bogie remain parallel to each other.
Un but de l'invention est de réaliser un bogie dans lequel chacun des essieux est orienté indépendamment de l'autre.An object of the invention is to produce a bogie in which each of the axles is oriented independently of the other.
L'invention a pour objet un bogie à deux essieux orientables, monté pivotant sous une caisse d'un véhicule ferroviaire, comportant un châssis relié à chaque essieu par l'intermédiaire de deux boîtes d'essieux et d'une suspension primaire, deux dispositifs articulés reliant chacun les deux boîtes d'essieux situées d'un même côté du châssis, et un dispositif de commande des deux dispositifs articulés permettant de faire converger les essieux dans les courbes, caractérisé en ce que le dispositif de commande comporte au moins un vérin relié au châssis du bogie et exerçant son action sur les dispositifs articulés, le vérin étant commandé par un ensemble capteur-émetteur d'informations, le capteur étant embarqué sur le bogie et l'émetteur étant placé à poste fixe à l'entrée d'une courbe de la voie.The subject of the invention is a bogie with two orientable axles, pivotally mounted under a body of a railway vehicle, comprising a chassis connected to each axle by means of two axle boxes and a primary suspension, two devices articulated each connecting the two axle boxes located on the same side of the chassis, and a control device for the two articulated devices allowing the axles to converge in curves, characterized in that the control device comprises at least one jack connected to the bogie chassis and exerting its action on the articulated devices, the jack being controlled by a sensor-information transmitter assembly, the sensor being on board the bogie and the transmitter being placed at a fixed position at the entrance to a track curve.
Pour éviter la transmission mécanique d'un effort entre le vérin et chaque palonnier d'un dispositif articulé, le dispositif de commande comporte deux vérins, chaque vérin actionnant un palonnier d'un dispositif articulé.To avoid the mechanical transmission of a force between the jack and each spreader of an articulated device, the control device comprises two jacks, each jack actuating a spreader of an articulated device.
Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, un bogie selon l'invention muni de deux vérins.There is described below, by way of example and with reference to the accompanying drawings, a bogie according to the invention provided with two jacks.
La figure 1 montre un tel bogie, en vue de dessus.Figure 1 shows such a bogie, seen from above.
La figure 2 montre le même bogie, vu de côté.Figure 2 shows the same bogie, seen from the side.
La figure 3 montre une suspension primaire selon III de la figure 2.FIG. 3 shows a primary suspension according to III in FIG. 2.
La figure 4 montre un longeron du bogie, en coupe selon IV de la figure 2.FIG. 4 shows a spar of the bogie, in section along IV of FIG. 2.
Dans la figure 1, le châssis de bogie est constitué de deux longerons 1 reliés par une traverse inférieure 2. La caisse est reliée au bogie par l'intermédiaire d'une couronne de pivotement 3 d'axe vertical central 4. Cette couronne est solidaire d'une traverse supérieure 5. Cette traverse 5 s'appuie, à chacune de ses extrémités, sur un longeron 1 du châssis par l'intermédiaire d'un ressort 6 formant suspension secondaire. Ce châssis porte deux essieux 7, chaque essieu étant porté par deux boîtes d'essieux 8.In FIG. 1, the bogie frame is made up of two longitudinal members 1 connected by a
Deux boîtes d'essieux 8 sont visibles dans la figure 2 et une seule est représentée dans la figure 3, celle-ci étant reliée élastiquement au châssis par quatre blocs élastiques 9 constitués d'éléments élastomères séparés par des plaques d'acier. La figure 2 montre qu'un longeron comporte, à chacune de ses extrémités, une pièce rapportée 10 qui reçoit deux blocs élastiques 9.Two
Chaque essieu 7 porte deux roues 11 et un ensemble moto-réducteur 12.Each
Les deux essieux sont orientables dans la mesure où l'axe principal 21 d'un essieu peut pivoter autour d'un axe fictif vertical 20 et selon un faible débattement, comme le montre les deux positions extrêmes 22, 23 que peut atteindre chaque axe d'essieu 21.The two axles are steerable insofar as the
Ce faible pivotement est assuré pour un essieu, par deux bielles 30, 31, la bielle 30 étant fixée à une boîte et logée dans un longeron, la bielle 31 étant fixée à l'autre boîte et logée dans l'autre longeron.This slight pivoting is ensured for an axle, by two connecting
Chaque bielle est articulée sur un palonnier 32, et chaque palonnier reçoit également une autre bielle. Un dispositif articulé, comportant un palonnier 32, une bielle 30 et une bielle 31, est alors logé dans un longeron et il actionne une boîte d'essieu de chaque essieu comme cela est bien visible figure 2.Each connecting rod is articulated on a
La figure 4 montre un longeron 1 constitué d'un assemblage de quatre plaques soudées entre elles, une plaque supérieure 1A, deux flancs 1B et une plaque inférieure 1C. Ce longeron renferme un palonnier 32 et les deux bielles 30, 31, le palonnier pivotant autour d'un axe 33 et étant actionné par un vérin 34 monté à l'extérieur de la plaque 1C, comme cela est bien visible figure 2. Ce vérin est alimenté en fluide par une source non représentée, et à travers une servo-valve non représentée.Figure 4 shows a beam 1 consisting of an assembly of four plates welded together, an upper plate 1A, two sides 1B and a lower plate 1C. This spar contains a
Le bogie comporte également un capteur embarqué 41 et une boîte électronique, non représentée, pilotant les deux servo-valves. La voie est munie d'un émetteur 42.The bogie also includes an on-
L'ensemble capteur-émetteur peut être de type code à barres, électromagnétique, ou guide d'ondes.The sensor-transmitter assembly can be of the barcode, electromagnetic, or waveguide type.
Un tel bogie fonctionne de la manière suivante :
à l'entrée d'une courbe, l'émetteur délivre un signal donnant les caractéristiques de cette courbe et le capteur réceptionne ce signal. La boîte électronique le traite et pilote les servo-valves qui commandent chacune un vérin.Such a bogie works in the following way:
at the entry of a curve, the transmitter delivers a signal giving the characteristics of this curve and the sensor receives this signal. The electronic box processes it and controls the servo-valves which each control a cylinder.
Dans la figure 2, la sortie de la tige du vérin 34 rapproche les deux roues 11, ce qui doit correspondre à une rentrée de la tige dans le vérin opposé pour éloigner les deux autres roues, et de la même valeur, afin d'obtenir un pivotement de chaque essieu autour de l'axe fictif 20.In FIG. 2, the output of the rod of the jack 34 brings the two
A la sortie de la courbe, les vérins sont réactivés en sens opposé, pour ramener les deux essieux parallèles.At the end of the curve, the jacks are reactivated in the opposite direction, to bring the two parallel axles.
Dans le cas d'une défaillance d'un dispositif articulé ou de son dispositif de commande lorsque le train roule à grande vitesse, la raideur de la suspension primaire est alors suffisante pour que le bogie reste stable en alignement.In the event of a failure of an articulated device or of its control device when the train is traveling at high speed, the stiffness of the primary suspension is then sufficient for the bogie to remain stable in alignment.
