- one of the two bearings is an elastic joint, and the other bearing is a spherical joint acting as an axial stop.
- An elastic articulation is preferably close to a spherical articulation in order to limit the mechanical forces on the parts constituting the articulation device.
- the central position of the axis of the articulation shaft allows the installation of a coaxial anti-roll device. This coaxiality cancels the distortion torque of the bogie due to the radial reactions of the bearings of the anti-roll device.
- the shaft is hollow and crossed by the anti-roll device consisting of a torsion bar comprising, at each end, a lever connected to the vehicle body by means of a connecting rod.
- the anti-roll device is constituted by the shaft itself which is extended beyond the elastic joints and which comprises, at each of its ends, a lever connected to the vehicle body by the through a connecting rod.

Abstract
Description
La présente invention concerne un bogie articulé pour véhicules ferroviaires, comportant deux longerons, deux traverses solidaires chacune d'un longeron, et un dispositif d'articulation autorisant une rotation de chaque longeron autour d'un axe transversal central. Cette rotation de chaque longeron permet de mieux répartir les charges verticales sur les quatre roues du bogie, particulièrement lors des passages comportant des variations de dévers, ou des défauts de nivellement de la voie.The present invention relates to an articulated bogie for railway vehicles, comprising two longitudinal members, two cross members each secured to a longitudinal member, and an articulation device allowing rotation of each longitudinal member around a central transverse axis. This rotation of each spar allows better distribution of the vertical loads on the four wheels of the bogie, particularly during passages with slope variations, or track leveling faults.
On connaît, notamment par la figure 2 du document FR-2 036 071, un tel bogie articulé.We know, in particular from Figure 2 of document FR-2 036 071, such an articulated bogie.
Dans ce bogie, les deux traverses sont interrompues, au niveau de l'axe central longitudinal, et raccordées élastiquement par l'intermédiaire du dispositif d'articulation constitué de deux platines comportant deux, quatre, ou huit blocs élastiques.In this bogie, the two crosspieces are interrupted, at the level of the longitudinal central axis, and connected elastically by means of the articulation device consisting of two plates comprising two, four, or eight elastic blocks.
La hauteur de ces platines est importante, comme le montre la figure 3 de ce document FR-2 036 071, ce qui rend la partie centrale de ce bogie très encombrante en hauteur, et donc inadaptée pour certaines applications, par exemple, pour un faible niveau de plancher par rapport aux rails .The height of these plates is important, as shown in Figure 3 of this document FR-2 036 071, which makes the central part of this bogie very bulky in height, and therefore unsuitable for certain applications, for example, for a low floor level in relation to the rails.
De plus, le dispositif d'articulation se trouve au niveau de l'axe central longitudinal du bogie, ce qui complique la fixation d'un moteur, car elle doit se faire sur une demi-traverse. Un tel bogie est donc principalement porteur.In addition, the articulation device is located at the level of the longitudinal central axis of the bogie, which complicates the fixing of a motor, since it must be done on a half-cross member. Such a bogie is therefore mainly carrier.
On connaît également, par le document GB-A-1203530, un bogie articulé comportant deux longerons et un dispositif d'articulation autorisant une rotation de chaque longeron autour d'un axe transversal central, le dispositif d'articulation comprenant deux parties d'arbre disposées selon l'axe transversal. Ces parties d'arbre sont supportées par des supports solidaires des longerons à raison de deux paliers lisses par support.Document GB-A-1203530 also discloses an articulated bogie comprising two longitudinal members and an articulation device allowing rotation of each longitudinal member around a central transverse axis, the articulation device comprising two shaft parts. arranged along the transverse axis. These shaft parts are supported by supports integral with the side members at the rate of two plain bearings per support.
La présente invention a pour but de diminuer l'encombrement vertical, tout en permettant une bonne fixation d'un moteur sur une traverse, ce bogie étant alors aussi bien moteur que porteur.The present invention aims to reduce the vertical size, while allowing a good fixing of an engine on a cross, this bogie then being both engine and carrier.
La solution proposée par la présente invention consiste à munir chaque longeron d'une traverse comportant une partie en forme de poutre, de monter ces deux traverses tête-bêche, et de les relier par un arbre n'autorisant qu'une rotation des longerons selon l'axe transversal central.The solution proposed by the present invention consists in provide each beam with a cross member having a beam-shaped part, mount these two cross beams, and connect them by a shaft allowing only a rotation of the beams along the central transverse axis.
La présente invention a pour objet un bogie articulé pour véhicules ferroviaires, comportant deux longerons, deux traverses solidaires chacune d'un longeron, et un dispositif d'articulation autorisant une rotation de chaque longeron autour d'un axe transversal central, le dispositif d'articulation comportant un arbre disposé selon un axe transversal et central au bogie et quatre paliers supportant l'arbre, caractérisé en ce que les traverses sont montées tête-bêche, chaque extrémité de l'arbre étant supportée par deux paliers dont l'un appartient à l'une des traverses et dont l'autre appartient à l'autre traverse.The present invention relates to an articulated bogie for railway vehicles, comprising two beams, two cross members each secured to a beam, and an articulation device allowing a rotation of each beam around a central transverse axis, the device articulation comprising a shaft arranged along an axis transverse and central to the bogie and four bearings supporting the shaft, characterized in that the cross members are mounted head to tail, each end of the shaft being supported by two bearings, one of which belongs to one of the sleepers and the other of which belongs to the other sleeper.
De préférence pour chaque extrémité d'arbre, l'un des deux paliers est une articulation élastique, et l'autre palier est une articulation sphérique jouant le rôle de butée axiale.Preferably for each shaft end, one of the two bearings is an elastic joint, and the other bearing is a spherical joint acting as an axial stop.
Une articulation élastique est de préférence voisine d'une articulation sphérique afin de limiter les efforts mécaniques sur les pièces constituant le dispositif d'articulation.An elastic articulation is preferably close to a spherical articulation in order to limit the mechanical forces on the parts constituting the articulation device.
La position centrale de l'axe de l'arbre d'articulation permet la mise en place d'un dispositif anti-roulis coaxial. Cette coaxialité annule le couple de distorsion du bogie dû aux réactions radiales des paliers du dispositif anti-roulis.The central position of the axis of the articulation shaft allows the installation of a coaxial anti-roll device. This coaxiality cancels the distortion torque of the bogie due to the radial reactions of the bearings of the anti-roll device.
Selon un premier mode de réalisation, l'arbre est creux et traversé par le dispositif anti-roulis constitué d'une barre de torsion comportant, à chaque extrémité, un levier relié à la caisse du véhicule par l'intermédiaire d'une bielle.According to a first embodiment, the shaft is hollow and crossed by the anti-roll device consisting of a torsion bar comprising, at each end, a lever connected to the vehicle body by means of a connecting rod.
Selon un deuxième mode de réalisation, le dispositif anti-roulis est constitué par l'arbre lui-même qui est prolongé au delà des articulations élastiques et qui comporte, à chacune de ses extrémités, un levier relié à la caisse du véhicule par l'intermédiaire d'une bielle.According to a second embodiment, the anti-roll device is constituted by the shaft itself which is extended beyond the elastic joints and which comprises, at each of its ends, a lever connected to the vehicle body by the through a connecting rod.
Il est décrit ci-après, à titre d'exemple et en référence aux figures annexées, un bogie selon l'invention.A bogie according to the invention is described below, by way of example and with reference to the appended figures.
La figure 1 montre une vue de dessus, schématique, d'un bogie sans dispositif anti-roulis.Figure 1 shows a schematic top view of a bogie without anti-roll device.
La figure 2 montre une vue centrale d'un bogie comportant un dispositif anti-roulis, selon le premier mode de réalisation.FIG. 2 shows a central view of a bogie comprising an anti-roll device, according to the first embodiment.
La figure 3 est une vue de côté selon III de la figure 2.FIG. 3 is a side view along III in FIG. 2.

Le dispositif d'articulation comporte un arbre 20 et quatre paliers 12, 13 Chaque traverse comporte deux paliers constitués l'un d'une articulation à rotule 12 et l'autre d'une articulation élastique 13. L'arbre 20 relie entre elles ces quatre articulations, et chaque longeron peut ainsi tourner autour de l'arbre transversal central 6.The articulation device comprises a
Cette figure montre l'écartement minimal qui peut exister entre les deux articulations élastiques afin d'éviter une rotation d'un longeron par rapport à l'autre selon l'axe central longitudinal. L'écartement maximal serait réalisé en logeant chaque articulation élastique dans un longeron, et, bien entendu, une position intermédiaire est possible, celle-ci étant déterminée en fonction de la place disponible.This figure shows the minimum spacing that can exist between the two elastic joints in order to avoid rotation of one spar relative to the other along the longitudinal central axis. The maximum spacing would be achieved by housing each elastic joint in a beam, and, of course, an intermediate position is possible, this being determined according to the space available.
Le bogie comporte également un dispositif d'entraînement 30 constitué de deux bielles 31 et d'un palonnier 32, chaque bielle étant reliée, de manière articulée, à une traverse 10. Ce dispositif d'entraînement permet d'appliquer au bogie des efforts principalement longitudinaux.The bogie also includes a
