L'invention concerne un bogie pour véhicules fer- The invention relates to a bogie for railway vehicles
roviaires, notamment pour véhicules ferroviaires surbaissés, dans lequel des ressorts hydropneumatiques sont disposés dans particularly for low-rail vehicles, in which hydropneumatic springs are arranged in
l'étage secondaire de suspension du bogie. the secondary suspension stage of the bogie.
Dans des véhicules ferroviaires surbaissés, la hauteur de construction des bogies est souvent réduite si fortement qu'il n'existe aucun espace de montage pour une traverse danseuse, qui permet un mouvement de rotation autour de l'axe vertical du bogie pendant le déplacement dans une courbe de la voie et transmet la force d'appui, des ressorts In lowered rail vehicles, the construction height of the bogies is often reduced so much that there is no mounting space for a bolster, which allows rotational movement around the vertical axis of the bogie during movement into the bogie. a curve of the track and transmits the support force, springs
disposés latéralement à l'extérieur au tourillon central. arranged laterally outside the central trunnion.
C'est pourquoi l'invention s'est fixé pour but de créer un bogie pour véhicules ferroviaires, dans lequel le problème Therefore, the purpose of the invention is to create a bogie for railway vehicles, in which the problem
mentionné précédemment soit évité. previously mentioned is avoided.
Ce but est atteint conformément à l'invention à l'aide d'un bogie pour véhicules ferroviaires, notamment pour véhicules ferroviaires surbaissés, qui est caractérisé en ce que - dans un étage de suspension secondaire du bogie, des ressorts hydropneumatiques à support pendulaire sont guidés, sur un chariot monté sur roulements, sur une trajectoire courbe, notamment un tronçon de trajectoire circulaire, - le centre de la trajectoire circulaire est situé sur l'axe vertical d'un tourillon, et - les ressorts hydropneumatiques à support pendulaire sont reliés, à leur partie supérieure, au chariot monté sur roulements et, à leur partie inférieure, à une console This object is achieved according to the invention by means of a bogie for railway vehicles, in particular for low-rail vehicles, which is characterized in that - in a secondary suspension stage of the bogie, hydropneumatic springs with pendular support are guided, on a carriage mounted on bearings, on a curved path, in particular a section of circular trajectory, - the center of the circular trajectory is located on the vertical axis of a trunnion, and - the hydropneumatic springs with pendular support are connected , at their upper part, to the carriage mounted on bearings and, at their lower part, to a console

Conformément à l'invention, le longeron du bogie possède des consoles disposées latéralement à l'extérieur, sur lesquelles est située la surface de palier et de roulement inférieure du support pendulaire. Au- dessus des ressorts hydropneumatiques, est disposé un chariot monté sur roulements, qui glisse sur un tronçon d'une piste circulaire autour du centre de l'axe de rotation vertical dans le véhicule. Le chariot est guidé, à l'aide d'une tringlerie ou de composants agissant de façon analogue, par le cadre du bogie, de sorte que les ressorts hydropneumatiques équipés du support pendulaire sont toujours verticaux, mais peuvent s'écarter latéralement. L'agencement ne requiert aucune forme de réalisation particulière du bogie. Ce dernier peut être aussi bien à un essieu qu'à plusieurs essieux. De même, le tourillon sur le bogie peut être accouplé par l'intermédiaire According to the invention, the beam of the bogie has brackets arranged laterally on the outside, on which is located the bearing surface and lower bearing of the pendular support. Above the hydropneumatic springs is arranged a carriage mounted on bearings, which slides on a section of a circular track around the center of the vertical axis of rotation in the vehicle. The carriage is guided, by means of a linkage or components acting in a similar way, by the frame of the bogie, so that the hydropneumatic springs equipped with the pendular support are always vertical, but can deviate laterally. The arrangement does not require any particular embodiment of the bogie. The latter can be both an axle and several axles. Similarly, the trunnion on the bogie can be coupled via
d'une barre articulée ou d'une bielle à lemniscate. an articulated bar or a lemniscate connecting rod.

invention ressortiront de la description donnée ci-après invention will emerge from the description given below
prise en référence aux dessins annexés, sur lesquels: - la figure 1 représente une coupe transversale d'une partie d'un bogie, selon l'invention, d'un véhicule ferroviaire surbaissé; et - la figure 2 représente une vue en plan prise Reference is made to the accompanying drawings, in which: - Figure 1 shows a cross section of a portion of a bogie, according to the invention, of a lowered rail vehicle; and - Figure 2 shows a plan view taken

Les figures 1 et 2 représentent un ressort hydro- Figures 1 and 2 show a hydraulic spring
pneumatique à support pendulaire 1, qui porte, à sa partie supérieure, un chariot 2 monté sur roulements. Ce chariot roule sur un tronçon d'une piste circulaire 3. Le support pendulaire du ressort hydropneumatique 1 est supporté, à sa partie inférieure, par une console 4 qui est raccordée au pneumatic pendulum support 1, which carries, at its upper part, a carriage 2 mounted on bearings. This carriage rolls over a section of a circular track 3. The pendulum support of the hydropneumatic spring 1 is supported, at its lower part, by a bracket 4 which is connected to the
longeron 5 du bogie.beam 5 of the bogie.
3 27342293 2734229
Le centre du tronçon de la piste circulaire 3 est situé sur l'axe vertical du tourillon 6. Ce dernier est relié à la traverse 8 du bogie, par exemple, par des bielles à lemniscate 7. Le chariot 2 monté sur roulements est guidé, lors de débattements angulaires du bogie, par une tringlerie 9 reliée à ce chariot et qui, de son côté, est reliée à un bras 10, qui est fixé au longeron 5 du bogie, de sorte que le ressort hydropneumatique 1 est toujours vertical lorsqu'on The center of the portion of the circular track 3 is located on the vertical axis of the journal 6. The latter is connected to the crossbar 8 of the bogie, for example, by rods lemniscate 7. The carriage 2 mounted on bearings is guided, during angular deflections of the bogie, by a linkage 9 connected to this carriage and which, for its part, is connected to an arm 10, which is fixed to the beam 5 of the bogie, so that the hydropneumatic spring 1 is always vertical when we
