Abstract

1. A railway vehicle comprissing a body and two motor bogies, each of the bogies being connected to the body by a single connecting rod (7'-9', 4'-6), one of the connecting rods being compressed in operation, while the other is extended, and vice-versa, according to the direction of travel, characterized in that each of the connecting rods is articulated between a point (7', 4') of the longitudinal axis of the bogie near the end of the body and a point (9', 6') of the longitudinal axis of the body near said end.

Description

La présente invention concerne un véhicule ferroviaire comportant une caisse et deux bogies, dont chacun est relié à la caisse par une seule bielle articulée entre un point de l'axe longitudinal du bogie proche de l'extrémité de la caisse et un point de l'axe longitudinal de la caisse proche de ladite extrémité, l'une des bielles travaillant en compression alors que l'autre travaille en traction, et vice-versa, selon le sens de la marche. Un tel véhicule permet de réduire les usures des boudins des roues dans le cas du parcours de voies courbes.The present invention relates to a railway vehicle comprising a body and two bogies, each of which is connected to the body by a single connecting rod articulated between a point of the longitudinal axis of the bogie close to the end of the body and a point of the longitudinal axis of the body close to said end, one of the connecting rods working in compression while the other working in traction, and vice versa, depending on the direction of travel. Such a vehicle makes it possible to reduce the wear of the flanges of the wheels in the case of the course of curved tracks.

Un véhicule de ce genre est décrit dans le document FR-A 2 190 656. Les figures 1 et 2 montrent comment ce résultat est atteint.A vehicle of this kind is described in document FR-A 2 190 656. FIGS. 1 and 2 show how this result is achieved.

La figure 1 représente le comportement d'un tel véhicule pour une locomotive ayant le sens de marche considéré, illustré par la flèche M. Le bogie 2 est le bogie avant et il pousse la caisse 1 au moyen de la bielle 7'-9', cette bielle étant disposée à l'avant du bogie avant en 7', un point d'articulation au bogie 2, et en 9', un point d'articulation avec la caisse 1. L'effort F transmis au bogie 2 en 7' par la bielle 7'-9' agit sur celle-ci en compression. L'effort F possède une composante longitudinale L égale à l'effort moteur du bogie 2 et une composante transversale T équilibrée par des réactions R1 et R2 de la voie sur les essieux qui sont de sens opposé aux réactions normales S1 et S2 dues aux glissements sur le rail et viennent donc en réduire la valeur. L'usure des boudins de la locomotive est donc faible.FIG. 1 represents the behavior of such a vehicle for a locomotive having the direction of travel considered, illustrated by the arrow M. The bogie 2 is the front bogie and it pushes the body 1 by means of the connecting rod 7'-9 ' , this connecting rod being disposed at the front of the front bogie in 7 ', a point of articulation to the bogie 2, and in 9', a point of articulation with the body 1. The force F transmitted to the bogie 2 in 7 'by the rod 7'-9' acts on it in compression. The force F has a longitudinal component L equal to the motor force of the bogie 2 and a transverse component T balanced by reactions R1 and R2 of the track on the axles which are in the opposite direction to the normal reactions S1 and S2 due to slipping on the rail and therefore come to reduce its value. The wear of the locomotive flanges is therefore low.

Quant au bogie arrière 2', il tire la caisse 1 au moyen de la bielle 4'-6' disposée à l'arrière du bogie arrière 2'. L'effort F transmis par la bielle sur.la caisse agit cette fois en traction mais les réactions R3, R4 de la voie sur les essieux et équilibrant la composante transversale T sont de sens opposé aux réactions S3 et S4 dues aux glissements des essieux sur le rail et viennent donc toujours en réduire la valeur.As for the rear bogie 2 ', it pulls the body 1 by means of the connecting rod 4'-6' disposed at the rear of the rear bogie 2 '. The force F transmitted by the connecting rod on the body acts this time in traction but the reactions R3, R4 of the track on the axles and balancing the transverse component T are in the opposite direction to the reactions S3 and S4 due to the sliding of the axles on the rail and therefore always come to reduce its value.

Le même raisonnement s'applique pour le sens de marche inverse de la figure 2. Dans ce cas le bogie 2' est le bogie avant et il pousse la caisse 1 au moyen de la bielle 4'-6'. La bielle 4'-6' est disposée cette fois à l'avant du bogie avant 2', et elle travaille en compression. Le bogie 2 est le bogie arrière et il tire la caisse 1 au moyen de la bielle 7'-9'. La bielle 7'-9' est disposée à l'arrière du bogie arrière 2 et elle travaille en traction.The same reasoning applies for the reverse direction of FIG. 2. In this case the bogie 2 'is the front bogie and it pushes the body 1 by means of the connecting rod 4'-6'. The 4'-6 'rod is arranged this times at the front of the bogie before 2 ', and it works in compression. The bogie 2 is the rear bogie and it pulls the body 1 by means of the connecting rod 7'-9 '. The rod 7'-9 'is disposed at the rear of the rear bogie 2 and it works in traction.

La disposition des bielles 7'-9' et 4'-6' entre les bogies et la caisse de la locomotive vers l'extérieur de cette caisse permet donc en courbe, de réduire les efforts transversaux agissant sur les boudins de toutes les roues au moment où sous l'action des efforts moteurs, les glissements entre ces roues et le rail sont les plus importants et les usures les plus rapides.The arrangement of the connecting rods 7'-9 'and 4'-6' between the bogies and the locomotive body towards the outside of this body therefore makes it possible in curves, to reduce the transverse forces acting on the flanges of all the wheels at when under the action of the engine forces, the slippage between these wheels and the rail is greatest and the wear is the fastest.

Cependant les bielles 7'-9' et 4' travaillent dans ce cas aussi bien en compression qu'en traction. Ceci oblige à surdimensionher la section droite des bielles pour leur permettre de répondre aux contraintes de compression aussi bien que de traction.However, the connecting rods 7'-9 'and 4' work in this case both in compression and in traction. This requires oversizing the cross section of the connecting rods to allow them to respond to compression as well as tensile stresses.

L'invention a pour but de permettre l'utilisation de bielles de section droite modérée dans un véhicule ferroviaine dont chaque bogie est relié à la caisse par une seule bielle fonctionnant en traction ou en compression de façon à réduire l'usure des boudins des roues.The invention aims to allow the use of connecting rods of moderate cross section in a railroad vehicle each bogie of which is connected to the body by a single connecting rod operating in traction or in compression so as to reduce the wear of the flanges of the wheels. .

Le véhicule ferroviaire selon l'invention est caractérisé en ce que ses bielles de liaison entre caisse et bogie sont pleines, au moins à leurs deux extrémités, et de section droite progressivement croissante à partir de leurs extrémités.The rail vehicle according to the invention is characterized in that its connecting rods between body and bogie are full, at least at their two ends, and of cross section progressively increasing from their ends.

Selon une particularité de l'invention l'articulation de ladite bielle ne comporte pas de jeu.According to a feature of the invention, the articulation of said connecting rod does not include any play.

Selon une autre particularité de l'invention ladite bielle est métallique.According to another feature of the invention, said connecting rod is metallic.

Selon une autre particularité de l'invention ladite bielle est pleine à ses deux extrémités et creuse sous forme de tube cylindrique en son milieu.According to another feature of the invention, said connecting rod is full at its two ends and hollow in the form of a cylindrical tube in the middle.

En se référant aux figures schématiques 3 à-5 ci-jointes on va décrire ci-après un exemple de mise en oeuvre de la présente invention. Les mêmes éléments représentés sur plusieurs de ces figures portent sur toutes celles-ci les mêmes références.With reference to the attached schematic figures 3 to 5, an example of the implementation of the present invention will be described below. The same elements shown in several of these figures bear the same references on all of them.

  • La figure 3 représente une vue latérale schématique d'une bielle selon l'invention et de ses articulations.Figure 3 shows a schematic side view of a connecting rod according to the invention and its joints.
  • La figure 4 représente une vue latérale schématique d'une autre bielle selon l'invention avec les mêmes articulations.Figure 4 shows a schematic side view of another connecting rod according to the invention with the same joints.
  • La figure 5 représente une vue latérale schématique d'une variante des articulations comportant des éléments en élastomère.FIG. 5 represents a schematic side view of a variant of the joints comprising elastomer elements.

Sur la figure 3 on voit une bielle 100 reliant les points d'articulation 7' et 9' ou 4' et 6'. La bielle 100 est dimensionnée de telle sorte qu'elle peut supporter les efforts de compression ou de traction et pour cela la section de la bielle 100, métallique et pleine, est plus importante au milieu de là bielle qu'aux extrémités, la variation de la section étant progressive.In Figure 3 we see a connecting rod 100 connecting the points of articulation 7 'and 9' or 4 'and 6'. The connecting rod 100 is dimensioned so that it can withstand compression or tensile forces and for this the section of the connecting rod 100, metallic and solid, is greater in the middle of the connecting rod than at the ends, the variation in the section being progressive.

L'articulation 9' appartient à la caisse 1 et l'articulation 7' au bogie 2. La bielle 100 comporte à ses extrémités des rotules 11 qui coopèrent avec et sont traversées par les axes 12 et 13 disposés dans des chapes 14 et 15 fixées respectivement dans les châssis de caisse et de bogie. Il est à noter qu'au lieu de rotules telles que 11 on peut envisager des orifices dans les extrémités des bielles assurant un rôle équivalent qui est de transférer les efforts de la chape à la bielle ou inversement et de permettre une rotation de la bielle autour de l'axe.The articulation 9 'belongs to the body 1 and the articulation 7' to the bogie 2. The connecting rod 100 has at its ends ball joints 11 which cooperate with and are crossed by the axes 12 and 13 arranged in fixed yokes 14 and 15 respectively in the body and bogie chassis. It should be noted that instead of ball joints such as 11, it is possible to envisage orifices in the ends of the connecting rods ensuring an equivalent role which is to transfer the forces from the yoke to the connecting rod or vice versa and to allow rotation of the connecting rod around of the axis.

Les axes 12 et 13 présentent des têtes d'arrêt 16, 17 inversées afin de faciliter leur pose mais des têtes disposées dans le même sens peuvent être aussi envisagées.The axes 12 and 13 have reverse stop heads 16, 17 in order to facilitate their installation, but heads arranged in the same direction can also be envisaged.

Sur la figure 4 on voit des articulations 7' et 9' identiques à celles de la figure 5 mais une bielle 100' représente une variante de la bielle 100. La bielle 100' est constituée d'extrémités métalliques 18 et 19 de sections progressivement croissantes et pleines et d'une partie médiane 20 métallique et creuse en forme de tube cylindrique, par exemple, soudé aux extrémités 18 et 19 par des soudures telles que 21.In FIG. 4 we see articulations 7 ′ and 9 ′ identical to those of FIG. 5 but a connecting rod 100 ′ represents a variant of the connecting rod 100. The connecting rod 100 ′ is made up of metal ends 18 and 19 of progressively increasing sections and solid and of a metallic and hollow central part 20 in the form of a cylindrical tube, for example, welded to the ends 18 and 19 by welds such as 21.

Sur la figure 5 on voit une articulation telle que 7' remarquable en ce qu'elle comporte des éléments en élastomère qui ont l'avantage d'amortir les chocs. On voit une bielle 100 (ou 100') traversant une pièce fixe 22 solidaire du châssis de caisse ou de bogie. La pièce fixe 22 comporte un orifice 23 par lequel passe l'extrémité de la bielle 100. Sur cette extrémité de la bielle 100 sont montés deux éléments en élastomère 24, 25 maintenus en position par deux butées métalliques 26, 27 ; l'une des butées 26 s'appuie sur un épaulement 28 de la bielle 100, l'autre butée 26 s'appuie par l'intermédiaire d'une rondelle 29 sur un écrou 30. Les éléments en élastomère 24, 25 assurent le transfert des efforts de la bielle 100 à la pièce fixe 22 ou inversement.In Figure 5 we see an articulation such as 7 'remarkable in that it comprises elastomer elements which have the advantage of absorbing shocks. We see a connecting rod 100 (or 100 ') passing through a fixed part 22 secured to the body or bogie chassis. The fixed part 22 has an orifice 23 through which the end of the connecting rod 100 passes. On this end of the connecting rod 100 are mounted two elastomer elements 24, 25 held in position by two metal stops 26, 27; one of the stops 26 rests on a shoulder 28 of the connecting rod 100, the other stop 26 is supported by a washer 29 on a nut 30. The elastomer elements 24, 25 ensure the transfer of forces from the connecting rod 100 to the fixed part 22 or vice versa.

Les applications du dispositif de la présente invention sont du domaine de l'aménagement des bogies et des châssis de véhicule ferroviaire ainsi que de leurs liaisons.The applications of the device of the present invention are in the field of fitting out bogies and rail vehicle chassis as well as their connections.
