Description

La présente invention se rapporte à un bogie ferroviaire muni d'appuis latéraux flottants à moyen anti-basculement pour deux structures wagon successives articulées sur ce même bogie.The present invention relates to a railway bogie with supports floating sides with medium anti-tilt for two successive wagon structures articulated on the same bogie.

La demande française n° 0202577 du 28 février 2002, du même déposant montre un appui latéral flottant pour deux structures wagon successives articulées sur un même bogie ferroviaire par l'intermédiaire d'une articulation commune de pivotement s'appuyant sur une crapaudine.French Application No. 0202577 of February 28 2002, same depositor shows lateral support floating for two successive wagon structures articulated on the same railway bogie by through a joint joint of pivoting based on a thrust.

Selon la présente invention on prévoit un appui latéral de part et d'autre de l'articulation centrale des deux structures wagon successives reposant sur un bogie commun. Chaque appui latéral se situe d'un côté entre les extrémités des deux structures wagon et la suspension au droit de ces extrémités ou lisoir.According to the present invention there is provision for lateral on either side of the central articulation two successive wagon structures based on a common truck. Each side support is on one side between the ends of the two wagon structures and the suspension to the right of these ends or to read.

Cette solution a pour but de désaccoupler les mouvements des extrémités des structures wagon, c'est-à-dire de rendre ces mouvements indépendants les uns des autres au niveau de l'appui sur la suspension latérale ou lisoir.This solution is intended to uncouple movements of the ends of the wagon structures, that is to say to make these movements independent of each others at the level of support on the suspension lateral or lip.

Cette solution a également pour but de diminuer les jeux et les amplitudes de mouvements des extrémités des structures wagon dans le cas de forces d'appui en opposition, c'est-à-dire en sens contraire.This solution also aims to decrease the games and the amplitudes of movements of ends of wagon structures in the case of forces support in opposition, that is to say in the opposite direction.

Cette solution apporte d'importants avantages.This solution brings important advantages.

L'indépendance de mouvement assure une grande fiabilité de fonctionnement et une meilleure longévité du matériel en raison de l'absence de sollicitation mécanique de l'une des structures wagon sur l'autre.Movement independence ensures a great reliable operation and better durability material due to lack of solicitation mechanics of one of the wagon structures on the other.

Grâce à l'invention, par la limitation de l'interaction des structures et des jeux verticaux, on peut transporter des charges de hauteur maximale dans la limite du gabarit ferroviaire.Thanks to the invention, by the limitation of the interaction of structures and vertical games, we can carry loads of maximum height in the rail gauge limit.

La constitution imaginée fonctionne par déplacement de plaques de friction l'une sur l'autre afin de dégrader l'énergie pour bénéficier d'un effet d'amortissement.The imagined constitution works by moving friction plates one over the other to degrade the energy to have an effect amortization.

Cependant, les mouvements des extrémités provenant du roulage ne sont que rarement des mouvements de roulis et de tangage purs. De ce fait, ils présentent fréquemment une composante de basculement souvent prépondérante en mouvement initial.However, the movements of the extremities from rolling are rarely pure roll and pitch movements. Thereby, they frequently exhibit a component of often overturning in initial motion.

Celle-ci s'exerçant sur les plaques d'appui et de support, dégrade la qualité d'appui de contact entre les plaques de friction et ainsi ne permet pas d'en obtenir tout l'effet escompté.This one exerted on the plates of support and support, degrades the quality of contact support between the friction plates and so does not allow to get all the desired effect.

De plus, la suspension du lisoir travaille de façon inégale ce qui la rend moins efficace et la fatigue. Dans les cas extrêmes, on peut aboutir à une déformation.In addition, the slider suspension works from unequal way which makes it less effective and the tired. In extreme cases, it can lead to deformation.

Le présent perfectionnement a pour but de réduire et de limiter le mouvement de basculement initial pour faire travailler la suspension du lisoir dans de bonnes conditions et assurer un bon contact uniforme entre les plaques de friction permettant ainsi de bénéficier d'un amortissement constant dont le plein effet existe dès le début.The present improvement aims to reduce and limit tipping movement initial to make the suspension of the light in good conditions and ensure good contact uniform between the friction plates thus allowing to benefit from a constant amortization of which the full effect exists from the beginning.

Il a pour but également d'augmenter l'effet recherché d'amortissement dans le cadre de ce type d'appui flottant.It also aims to increase the effect sought depreciation under this type floating support.

On le décrira ci-après dans le cas de deux variantes principales.It will be described hereinafter in the case of two main variants.

A cet effet, on présentera ci-après, à chaque fois, les principaux éléments constitutifs de l'appui latéral flottant tel que déjà décrit dans un dépôt antérieur.For this purpose, it will be presented below, at each times, the main building blocks of the support lateral floating as already described in a deposit prior.

La présente invention s'applique à deux structures wagon successives 1 et 2 de gauche à droite sur la figure 2, dont les extrémités opposées 3 et 4 sont articulées sur le même bogie 5 présentant deux essieux 6 et 7 et un châssis 8. Ce châssis 8 porte une crapaudine 9 à corps semi-sphérique 10 formée de deux pièces complémentaires d'articulation dont une coque sphérique réceptrice 11 et une sphère 12 emboítée dans cette coque réceptrice (figure 9). The present invention applies to two successive wagon structures 1 and 2 from left to right in Figure 2, the opposite ends 3 and 4 are articulated on the same bogie 5 having two axles 6 and 7 and a chassis 8. This chassis 8 carries a crapaudine 9 with semi-spherical body 10 formed of two additional hinge parts including a hull spherical receiver 11 and a sphere 12 fitted into this receiver shell (Figure 9).

La crapaudine 9 est reliée à une articulation centrale commune de pivotement 13 avec débattement en basculement latéral constituant l'articulation principale par laquelle les extrémités 3 et 4 sont reliées entre elles à pivotement.Crapaudine 9 is connected to a joint common central pivot 13 with clearance in lateral tilting constituting the articulation principal by which the ends 3 and 4 are connected to each other pivotally.

La crapaudine 9 et l'articulation centrale 13 forment une articulation composite à trois degrés de liberté autorisant toutes les inclinaisons liées aux mouvements de roulage et parmi eux les mouvements de roulis et de tangage.Crapaudine 9 and the central articulation 13 form a composite articulation with three degrees of freedom allowing all the inclinations related to movements of rolling and among them the movements of roll and pitch.

Les extrémités opposées 3 et 4 des structures wagon sont reliées entre elles de chaque côté par une liaison latérale spécifique à discontinuité occasionnelle 14 et 15.Opposite ends 3 and 4 of structures wagon are interconnected on each side by a specific lateral connection with discontinuity occasional 14 and 15.

Afin de supporter les extrémités des structures wagon successives 1 et 2 dans leurs mouvements, il existe deux appuis latéraux mobiles 16 et 17 sur chacun desquels porte un élément d'extrémité d'une des liaisons latérales discontinues respectivement 14 et 15.In order to support the ends of successive wagon structures 1 and 2 in their movements, there are two movable side supports 16 and 17 on each of which carries an end element of one of the discontinuous lateral connections respectively 14 and 15.

Ces liaisons latérales discontinues 14 et 15 sont constituées, selon la présente invention des moyens suivants. Une embase 18 mobile verticalement est montée sur un dispositif de suspension à butées formant un ensemble de suspension 19 appelé communément dans le langage technique lisoir. Une plaque d'appui et de support 20, en contact de frottement avec la face supérieure ou la garniture de l'embase 18, présente un support 21 porte articulation recevant une articulation 22 par exemple une articulation du type à axe de pivotement 23.These discontinuous lateral bonds 14 and 15 are constituted, according to the present invention, following means. A vertically movable base 18 is mounted on a suspension device with stops forming a suspension assembly 19 commonly called in the technical language. A support plate and support 20, in frictional contact with the face upper or the lining of the base 18, has a support 21 articulation door receiving a joint 22 for example a hinge type axis pivoting 23.

Les extrémités 3 et 4 des structures wagon 1 et 2 comportent au niveau de chaque liaison latérale discontinue 14 et 15 des prolongations sous la forme de pattes d'extrémité réalisant au niveau de chaque liaison latérale discontinue, d'un côté une jonction avec le lisoir, et de l'autre côté une liaison à discontinuité occasionnelle ouverte ou fermée selon que l'extrémité de la patte d'extrémité correspondante est en position relevée ou en contact d'appui. Ces pattes d'extrémité, présentes de chaque côté, sont de deux types : une patte d'extrémité à fourche 24 pour l'extrémité 3 et une patte double d'extrémité 25 pour l'extrémité 4 en regard de part et d'autre de l'articulation principale 13.The ends 3 and 4 of the wagon structures 1 and 2 have at each side link discontinuous 14 and 15 extensions in the form of end brackets realizing at the level of each discontinuous lateral connection, on one side a junction with the light, and on the other side a link to occasional discontinuity open or closed as the end of the corresponding end tab is in raised position or in contact with support. These legs end, present on each side, are two types: a fork end tab 24 for the end 3 and a double end tab 25 for end 4 opposite each side of the main articulation 13.

La patte double d'extrémité 25 est formée de deux éléments 26 et 26a dont l'un au moins, mais de préférence les deux, présentent une sous face sensiblement horizontale disposée en regard de la plaque d'appui et de support 20.The double end tab 25 is formed of two elements 26 and 26a, at least one of which, but preferably both, have an underside substantially horizontal disposed opposite the support and support plate 20.

Plus particulièrement, chaque appui latéral d'articulation selon l'invention présente les composants suivants.More particularly, each lateral support of articulation according to the invention presents the following components.

L'embase 18 en forme de plateau est montée coulissante verticalement par sa partie centrale 27 par exemple en saillie cylindrique pour venir coulisser à guidage dans un logement 28 par exemple cylindrique ménagé dans un support fixe 29 solidaire du châssis 8 du bogie. Le guidage est amélioré par un plot central 30 s'engageant à coulissement dans une cavité centrale 31.The base 18 in the form of a plateau is mounted sliding vertically by its central portion 27 by example protruding cylindrical to slide to guiding in a housing 28 for example cylindrical arranged in a fixed support 29 secured to the chassis 8 of the bogie. Guiding is improved by a central block 30 slidingly engaged in a central cavity 31.

L'embase 18 est montée sur une suspension constituée d'au moins deux ressorts de compression 32 et 33 sur l'extrémité desquels elle repose par ses parties d'extrémité pour former l'ensemble de suspension 19. Les ressorts 32 et 33 de la suspension sont guidés par des pièces intérieures 34 et 35 le long desquelles ils se déplacent dans un mouvement de compression-relâchement correspondant à leur travail de suspension.The base 18 is mounted on a suspension consisting of two or more compression springs 32 and 33 on the end of which it rests by its end parts to form the set of suspension 19. The springs 32 and 33 of the suspension are guided by inner pieces 34 and 35 along from which they move in a movement of compression-looseness corresponding to their work of suspension.

Ces pièces intérieures 34 et 35 représentées sur les figures 6 et 8 jouent également le rôle de butée et de guidage. On les appellera par la suite pièces de guidage et de butée. En effet, la sous face de l'embase 18 vient en bout de course, en contact de butée avec la face frontale de ces pièces de butée et de guidage lors des mouvements de grande amplitude correspondant au débattement de l'embase 18 permettant d'amortir les mouvements.These inner parts 34 and 35 shown Figures 6 and 8 also play the role of stop and guide. We will call them later guiding and abutment parts. Indeed, the underside of the base 18 comes to the end of the race, in contact with stop with the front face of these abutment pieces and guidance during large amplitude movements corresponding to the travel of the base 18 allowing to dampen the movements.

On distingue ensuite la plaque d'appui et de support 20 montée en appui de frottement sur la face supérieure de l'embase 18 garnie d'une pièce d'appui et de frottement 36. La plaque d'appui et de support 20 peut être réalisée selon différentes variantes technologiques par exemple en une structure composite formée de plusieurs plaques superposées par exemple trois comme représenté sur les figures ou toute autre constitution.We then distinguish the support plate and support 20 mounted in frictional support on the face upper base 18 furnished with a support piece and friction 36. The support plate and support 20 can be made according to different variants technological for example in a composite structure formed of several superimposed plates for example three as depicted in the figures or any other constitution.

La plaque d'appui et de support 20 présente sur sa face supérieure une zone de portée-friction 37 s'étendant par exemple de part et d'autre et autour du support d'articulation 21. Cette zone de portée-friction 37 est garnie autour du support d'articulation 21 mais à distance de celui-ci, d'un insert de friction 38 d'une seule pièce et en forme de cadre ou en plusieurs pièces sur lequel vient porter chacune des semelles correspondantes 39 et 40 dont est équipée la sous face respectivement des éléments 26 et 26a de la patte double d'extrémité 25.The bearing plate and support 20 presents on its upper surface a friction-grip zone 37 extending for example on both sides and around the articulation support 21. This friction-grip zone 37 is lined around the hinge support 21 but away from it, a friction insert 38 one-piece and frame-shaped or in several pieces on which comes to wear each of corresponding soles 39 and 40 which is equipped with underface respectively elements 26 and 26a of the double end tab 25.

L'insert de friction 38 en cadre est placé par exemple à distance par son périmètre intérieur des bords du support d'articulation 21 et légèrement en retrait vers le bas par rapport au plan de la face supérieure de la plaque 20 d'appui et de support. Il garnit à encastrement la zone de portée-friction 37 et se trouve réalisé sous la forme d'une plaque massive ou à revêtement, en un matériau à fort coefficient de frottement permettant de dégrader une partie importante de l'énergie lors du travail d'appui et de déplacement en glissement-friction de la semelle 39 ou 40 de chaque sous face des éléments 26 et 26a composant la patte double d'extrémité 25 et l'insert de friction 38 de la zone de portée-friction 37 en regard.The friction insert 38 in the frame is placed for example remotely by its inner perimeter of edges of the hinge support 21 and slightly in withdrawal towards the plane of the face upper plate 20 support and support. he flush-fitting the friction-reach zone 37 and is realized in the form of a massive plate or coated, made of a material with a high coefficient of friction to degrade an important part energy during support and displacement work slip-friction of the sole 39 or 40 of each underface of the elements 26 and 26a composing the leg double end 25 and the friction insert 38 of the friction-bearing zone 37 opposite.

Il peut exister deux inserts 38 l'un et l'autre présents sur les parties longitudinales adjacentes au support 21 porte articulation.There may be two inserts 38 one and the other present on the longitudinal parts adjacent to the support 21 articulation door.

Selon la première variante représentée, ce support 21 porte articulation est conformé en étrier vertical et se présente sous la forme d'un bloc mécanique formé par exemple de deux pièces de flanc assemblées par un pion 41 à la plaque d'appui et de support 20. Le support 21 comporte dans sa partie supérieure un logement de déplacement 42 pour l'axe de pivotement 22. Ce logement 42 est formé d'une cavité cylindrique transversale inférieure se prolongeant vers le haut par deux branches ouvertes ou jumelées par une liaison transversale de sécurité. L'axe de pivotement 22 de l'articulation peut se déplacer le long de ce logement 42 entre une position haute et une position basse et inversement. Sur cet axe de pivotement 22 sont montées les extrémités latérales de la patte à fourche 24. Le logement de déplacement 42 présente à l'effet de déplacement de l'axe 22 une section transversale de forme sensiblement oblongue ouverte vers le haut mais de préférence à sortie condamnée par la liaison transversale de sécurité par exemple par des boulons transversaux (non représentés).According to the first variant represented, this support 21 door hinge is shaped in stirrup vertical and is in the form of a block mechanical formed for example of two flank pieces assembled by a pin 41 to the support plate and 20. The support 21 has in its part upper displacement housing 42 for the axis of 22. This housing 42 is formed of a cavity lower transverse cylindrical extending towards the top by two branches open or twinned by a transversal safety connection. The pivot axis 22 of the joint can move along this housing 42 between a high position and a position low and vice versa. On this pivot axis 22 are mounted the lateral ends of the fork leg 24. Displacement dwelling 42 has the effect of displacement of the axis 22 a cross section of substantially oblong shape open upward but preferably with an exit condemned by the link transversal safety for example by bolts transversal (not shown).

La mobilité verticale de l'axe de pivotement 22 entre une position basse et une position haute le long de son logement de déplacement 42 représente le débattement vertical utilisé comme liberté de mouvement conjointement avec le montage flottant de la plaque d'appui et de support 20 et la latitude de mouvement existant entre la patte d'extrémité 25 et la plaque d'appui et de support 20. Cette latitude de mouvement correspond à la course entre l'appui et la position relevée de la patte double 25 comme il sera décrit ci-après dans l'explication du fonctionnement. On utilise également la mobilité inverse c'est-à-dire celle du support d'articulation 21 par rapport à l'axe de pivotement 22 qui, dans ce cas est fixe. Bien entendu, tous les cas de combinaison de ces mobilités sont possibles.Vertical mobility of the pivot axis 22 between a low position and a high position on along its displacement housing 42 represents the vertical deflection used as freedom of movement together with the floating mounting of the plate of support and support 20 and the latitude of movement existing between the end tab 25 and the plate of support and support 20. This latitude of movement corresponds to the race between the support and the position raised the double leg 25 as will be described below in the explanation of the operation. We use also the reverse mobility that is to say that of the articulation support 21 with respect to the axis of pivoting 22 which in this case is fixed. Of course, all cases of combination of these mobilities are possible.

Selon une variante, on peut réaliser le support 21 porte articulation mobile par rapport à la plaque 20 d'appui et de support pour obtenir une totale indépendance de mouvements entre l'une et l'autre extrémités des structures wagon. Selon cette variante, le support 21 porte articulation traverse ainsi la plaque 20 d'appui et de support pour exercer directement sa force de poussée sur et contre la pièce de friction 36 de l'ensemble de suspension 19 formant lisoir. A cet effet, ce support 21 peut être monté à coulissement dans un évidemment traversant au centre de la plaque 20 d'appui et de support (non représenté). Un mouvement guidé par des rainures, des gorges ou autres moyens permettrait un bon fonctionnement et une présentation correcte d'appui de la base de ce support 21. Bien entendu, dans ce cas, le débattement de l'axe 22 le long de son logement n'est plus totalement nécessaire car celui-ci est assuré par le déplacement de son support 21.According to one variant, the support 21 door hinge movable relative to the support plate 20 and support to obtain a total independence of movement between one and the other ends of wagon structures. According to this variant, the support 21 door hinge thus passes through the plate 20 support and support for exercise directly its pushing force on and against the piece of friction 36 of the suspension assembly 19 forming side bearers. For this purpose, this support 21 can be mounted to sliding in a obviously crossing at the center of the support and support plate 20 (not shown). A movement guided by grooves, grooves or other means would allow proper functioning and correct presentation of support of the base of this support 21. Of course, in this case, the deflection of the axis 22 along his housing is no longer totally necessary because it is ensured by the displacement of its support 21.

On peut également envisager une variante selon laquelle le support d'articulation est mobile par rapport à la plaque d'appui et de support 20, mais agit indirectement sur le lisoir et ceci à travers cette plaque 20. Dans ce cas, il est possible de prévoir un débattement supplémentaire entre le support d'articulation et la plaque 20 par un intervalle avant contact.It is also possible to envisage a variant that the hinge support is movable by relative to the support and support plate 20, but acts indirectly on the light and this through this In this case, it is possible to provide a additional travel between the support of hinge and the plate 20 by a gap before contact.

En roulage, selon les mouvements provenant d'une structure wagon ou de l'autre ou d'un côté ou de l'autre de la même structure wagon, les appuis latéraux flottants vont travailler en se déplaçant dans un sens ou dans un autre par exemple du bas vers le haut ou inversement.In rolling, according to movements from of a wagon structure or the other or on one side or the other of the same wagon structure, the lateral supports floats are going to work by moving in one direction or in another for example from bottom to top or Conversely.

Les positions extrêmes sont représentées sur les figures 5 à 8.The extreme positions are represented on Figures 5 to 8.

Dans le cas d'une poussée provenant de la structure wagon 1 de gauche (figures 5 et 6), lors d'un basculement vers le bas, la patte à fourche 24 d'extrémité va appuyer sur l'ensemble de suspension 19 ou lisoir par l'intermédiaire du support 21 porte articulation jusqu'à compensation ou contact de butée par les ressorts de compression 32 et 33 de l'ensemble de suspension 19 sur les pièces intérieures de butée et de guidage 34 et 35. En effet, dès que l'axe de pivotement 22 arrive en butée de fond de logement 42, l'ensemble de suspension s'affaisse dans un mouvement amorti sous la poussée de l'extrémité 3 correspondante de la structure wagon 1 en raison du travail des ressorts de la suspension.In the case of a push coming from the wagon structure 1 on the left (Figures 5 and 6), during a tilting down, the fork leg 24 end will press the suspension assembly 19 or lip through the support 21 door articulation until compensation or stop contact by the compression springs 32 and 33 of the assembly suspension 19 on the inner stops and 34 and 35. Indeed, as soon as the axis of pivoting 22 arrives at the bottom abutment 42, the suspension assembly sags in a movement cushioned under the thrust of the corresponding 3 end of the wagon 1 structure because of the work of the springs of the suspension.

Si la poussée présente en plus une composante horizontale, la plaque d'appui et de support 20 ripe par glissement de friction sur la pièce intercalaire d'appui et de frottement 36.If the thrust additionally has a component horizontal, the support plate and support 20 ripe sliding friction on the insert support and friction 36.

L'axe de pivotement 22 est prévu pour tourner dans son logement lors des basculements de tangage.The pivot axis 22 is intended to rotate in its housing during pitching changes.

Inversement, dans le cas des figures 7 et 8, la patte double d'appui 25 peut subir une poussée vers le bas et ce sont alors les deux éléments 26 et 26a de la patte double d'appui 25 qui affaissent l'ensemble de suspension 19 par appui de leurs semelles de garniture 39 et 40 sur la zone de portée-friction 37. L'ensemble de suspension 19 descend avec le support 21 porte articulation, laissant l'axe de pivotement 22 dans sa position dans son logement 42 grâce à la liberté de mouvement le long de ce logement à section oblongue.Conversely, in the case of Figures 7 and 8, the double support leg 25 can be pushed towards the bottom and these are then the two elements 26 and 26a of the double support leg 25 which sag the set of suspension 19 by support of their insoles 39 and 40 on the friction range 37. The assembly suspension 19 goes down with the support 21 door articulation, leaving the pivot axis 22 in its position in his dwelling 42 thanks to the freedom of movement along this oblong section housing.

Toute composition des mouvements ci-dessus est possible en raison de l'absence de liaison mécanique fonctionnelle entre les pattes 24 et 25.Any composition of the movements above is possible due to the lack of liaison functional mechanics between the legs 24 and 25.

On a ainsi rendu les mouvements de l'extrémité d'une structure wagon indépendants de ceux de l'extrémité de la structure wagon suivante dans la limite des débattements maximum en utilisation.We made the movements of the end of a wagon structure independent of those from the end of the next wagon structure in the limit of the maximum deflections in use.

Dans le cas de la variante à support 21 d'articulation coulissant indépendamment de la plaque 20 d'appui et de support, l'indépendance est totale. Chaque extrémité de chaque structure wagon peut se déplacer et agir seule sur la pièce de friction 36 du lisoir.In the case of the support variant 21 sliding hinge regardless of the plate 20 of support and support, independence is total. Each end of each car structure can be move and act alone on the friction piece 36 of the side bearers.

L'intérêt général des moyens décrits ci-dessus réside dans la présence d'au moins deux débattements, l'un au niveau du support 21 d'articulation et l'autre entre la patte d'extrémité 25 et la plaque 20 d'appui et de support, lors des mouvements dus au roulage.The general interest of the means described above lies in the presence of at least two deflections, one at the level of the support 21 hinge and the other between the end tab 25 and the support plate 20 and support, during movements due to rolling.

Selon les particularités des mouvements des extrémités, ces débattements ne sont pas forcément simultanés. Ils offrent dans tous les cas d'utilisation normale des structures wagon lors du roulage, une course à vide permettant d'éviter la transmission des mouvements à l'autre extrémité, sachant qu'en plus, ceux-ci sont amortis par les ressorts de l'ensemble de suspension 19.According to the particularities of the movements of extremes, these deflections are not necessarily concurrent. They offer in all cases of use normal wagon structures during taxiing, a empty race to prevent the transmission of movements at the other end, knowing that in addition, these are buffered by the springs of the set of suspension 19.

La deuxième variante sur laquelle s'applique la présente invention est représentée sur les figures 10 à 19. Elle comporte les mêmes fonctions générales et des moyens équivalents. Les mêmes éléments ou les éléments quasi identiques porteront les mêmes références numériques.The second variant to which applies the present invention is shown in the figures 10 to 19. It has the same general functions and equivalent means. The same elements or almost identical elements will wear the same numerical references.

On a cherché dans cette deuxième variante à descendre l'axe horizontal de pivotement référencé 23 de l'articulation de pivotement 22 le plus possible vers le lisoir de manière à réduire au maximum le couple de basculement. En effet, le frottement a pour effet de créer un couple et, plus la pièce de friction est éloignée de l'axe de pivotement, plus elle a tendance à s'arc-bouter. Il y a lieu de rendre cet effet minimal pour le bon fonctionnement, pour diminuer l'usure et pour éviter des couples préjudiciables à la stabilité en roulage des wagons.We looked in this second variant to down the horizontal pivot axis referenced 23 pivot joint 22 as much as possible towards the slider so as to minimize the tilt torque. Indeed, the friction has for effect of creating a couple and, plus the friction piece is away from the pivot axis, the more it has tendency to bend. It is appropriate to make this minimal effect for proper functioning, to decrease wear and to avoid couples detrimental to the stability when rolling wagons.

On retrouve ainsi l'embase 18 mobile verticalement montée sur un dispositif de suspension à butées formant l'ensemble de suspension 19 de bogie appelé communément dans le langage technique lisoir. Une plaque d'appui et de support 20 en contact de frottement avec la face supérieure ou la garniture de l'embase 18 présente un support 43 d'articulation recevant une articulation spéciale 44 de pivotement autour d'un axe horizontal et de translation verticale. Une articulation multidirectionnelle par exemple du type à rotule ou forme équivalente peut également convenir bien que, aux débattements de jeu près, seuls les mouvements de translation verticaux et de pivotement autour d'un axe horizontal passant par l'articulation soient concernés.We thus find the base 18 mobile vertically mounted on a suspension device to stops forming the bogie suspension assembly 19 commonly called in the technical language. A support and support plate 20 in contact with friction with the upper face or the lining of the base 18 has a support 43 of articulation receiving a special articulation 44 of pivoting around a horizontal axis and vertical translation. A multidirectional articulation for example of ball type or equivalent form can also to suit although, to the game clearances by, only vertical translation movements and pivoting around a horizontal axis passing through articulation are concerned.

Les pattes d'extrémité sont de forme quasi identique pour l'une d'entre elles 45 à deux branches 46 et 47 correspondant à la patte double 25, mais différente au niveau de son extrémité pour l'autre patte d'extrémité à savoir la patte centrale d'extrémité 48 qui se trouve montée en prise sur l'articulation 44.The end tabs are of quasi form identical for one of them 45 with two branches 46 and 47 corresponding to the double leg 25 but different at the end for the other end tab namely the central leg end 48 which is engaged on articulation 44.

En se référant plus particulièrement aux figures 11 et 12, la patte centrale d'extrémité 48 se termine par une extrémité regardant vers le bas et présentant une cavité formant un logement 49 pour l'articulation 44. Cette dernière porte sur le support d'articulation 43 réalisé sous la forme d'un bloc 50 par exemple parallélépipédique. Sur ce bloc support d'articulation est monté un élément récepteur 51 par exemple rectiligne comme visible sur la figure 12 coopérant avec un plot 52 équipant le fond du logement 49 afin de constituer un ensemble de sécurité pour le fonctionnement de l'articulation. Ce support d'articulation 43 réalisé sous la forme du bloc 50, comporte sur une partie de sa surface latérale une garniture de portée 53 à face extérieure convexe. Cette garniture de portée 53 se trouve lors du fonctionnement en regard d'une fourrure 54 rapportée sur la surface latérale du logement 49. Cette fourrure 54 présente une face extérieure plane, ce qui réduit la surface en contact avec la face extérieure de la garniture de portée 53.With particular reference to FIGS. 11 and 12, the central end tab 48 is ends with one end looking down and having a cavity forming a housing 49 for the articulation 44. The latter relates to the support hinge 43 made in the form of a block 50 for example parallelepipedic. On this support block of articulation is mounted a receiver element 51 by rectilinear example as shown in Figure 12 cooperating with a stud 52 equipping the bottom of the housing 49 to constitute a security package for the functioning of the joint. This support hinge 43 made in the form of block 50, has on one part of its lateral surface a bearing pad 53 with convex outer surface. This span pad 53 is found during operation next to a fur 54 reported on the surface housing 49. This fur 54 has a flat surface, which reduces the surface area contact with the outside of the filling of range 53.

Il faut comprendre qu'ici le support d'articulation 43 est le bloc support 50 sur la plaque d'appui et de support 20.It must be understood that here the support articulation 43 is the support block 50 on the plate support and support 20.

Comme précédemment, ce support d'articulation solidaire de la plaque 20 ou montée sur celle-ci peut être autrement relié ou en relation avec elle. En particulier, ce support d'articulation peut être monté mobile par rapport à la plaque 20.As before, this articulation support integral with the plate 20 or mounted thereon may to be otherwise connected or related to it. In particular, this articulation support can be mounted mobile with respect to the plate 20.

Les moyens mécaniques représentés et utilisés pour former l'articulation 44 portée par le support d'articulation 43 ont été choisis en raison des faibles amplitudes de débattement engendrées lors du fonctionnement.The mechanical means represented and used to form the hinge 44 carried by the support of articulation 43 were chosen because of the weak travel amplitudes generated during the operation.

En examinant les moyens décrits ci-dessus, on peut conclure que la fonction générale de désaccouplement des mouvements des pattes d'extrémité est bien remplie de la même façon conformément à l'invention. Il s'agit bien d'une variante entrant dans le cadre de la présente invention.By examining the means described above, can conclude that the general function of uncoupling the movements of the end tabs is fulfilled in the same way in accordance with the invention. It is indeed a variant entering into the scope of the present invention.

En ce qui concerne le fonctionnement, on se référera pour les principales phases à l'explication détaillée ci-dessus déjà décrite pour la première variante. La particularité du fonctionnement de cette deuxième variante vient du remplacement de l'articulation de pivotement 22 avec déplacement vertical de son axe 23 par une articulation spécifique 44. Le fonctionnement de cette articulation spécifique 44 permet de compléter l'explication du fonctionnement d'ensemble.As for the functioning, we are will refer for the main phases to the explanation detailed above already described for the first variant. The peculiarity of the operation of this second variant comes from the replacement of the pivot joint 22 with displacement vertical axis 23 by a specific articulation 44. The functioning of this specific articulation 44 completes the explanation of how overall.

Lors d'une prise de courbe ou lors d'un autre fait générateur de mouvement au niveau des pattes d'extrémité, la patte double d'extrémité 45 agit par appui glissant de la même façon que celle de la première variante. Par contre, la patte d'extrémité centrale 48 transmet directement le mouvement qui l'anime à l'articulation 44. Celle-ci permet d'absorber les types de déviations et de déplacements générés qu'ils soient verticaux, ou d'inclinaison autour d'un axe horizontal de pivotement et de les amortir par friction sur la ou les garniture(s) de friction et obtenir le désaccouplement qui est le but principal de l'invention.When taking a curve or at another makes movement generator at the level of the legs end, the end double tab 45 acts by sliding support in the same way as that of the first variant. By cons, the end tab central 48 directly transmits the movement that the anime at the joint 44. This allows to absorb the types of deviations and displacements generated whether they are vertical, or tilting around a horizontal pivot axis and damping them by friction on the friction lining (s) and get the uncoupling which is the main purpose of the invention.

L'idée générale inventive du présent perfectionnement consiste à prévoir un moyen anti-basculement en particulier un moyen de limitation du basculement pour la plaque d'appui et de support 20 par laquelle le dispositif d'appui flottant est en contact avec le lisoir.The inventive general idea of the present improvement consists in providing anti-tipping means in particular a means of limiting the tilting for the support plate and support 20 by which the floating support device is in contact with the light.

Ce moyen peut être simple ou double, sous la forme d'un cadre ou d'une glissière ou de deux appuis d'extrémité ou de toute autre solution mettant en oeuvre des moyens classiques ou de fonctions secondaires dont la combinaison aboutit au même résultat d'ensemble.This means can be single or double, under the a frame or a slide or two supports end or any other solution implementing classical means or functions the combination of which leads to the same overall result.

On décrira ci-après à titre d'exemple non limitatif, un des moyens à base de deux lames de torsion dont une extrémité de chacune est fixée sur une extrémité de la plaque d'appui et de support 20 et dont l'autre extrémité de chacune est fixée sur une platine faisant partie du châssis du bogie ferroviaire ou de sa crapaudine.Hereinafter will be described by way of example no limiting, one of the means based on two blades of torsion of which one end of each is fixed on a end of the support plate and support 20 and whose the other end of each is fixed on a platinum forming part of the chassis of the railway bogie or its crapaudine.

Le présent perfectionnement concerne un moyen limitant le mouvement de basculement initial provenant de l'appui de la patte d'extrémité à fourche 24 par l'intermédiaire de l'axe de pivotement 23 et/ou de l'appui de la patte double d'extrémité 25.The present improvement concerns a means limiting the initial tilting movement from from the support of the fork end tab 24 by intermediate pivot axis 23 and / or the support of the double end tab 25.

En raison du caractère symétrique de l'appui, le moyen se compose de deux éléments semblables raidisseurs fixés aux extrémités longitudinales de la plaque d'appui et de support 20 jouant le rôle de structure d'appui sur l'embase du lisoir.Due to the symmetrical nature of the support, the medium consists of two similar elements stiffeners attached to the longitudinal ends of the support plate and support 20 playing the role of support structure on the collar of the collar.

Selon la variante représentée, il s'agit de deux lames métalliques indépendantes de torsion 55 et 56 dont respectivement l'une des extrémités 57 et 58 est fixée sur une extrémité de la plaque d'appui et de support et dont l'autre extrémité respectivement 59 et 60 est montée sur un support indépendant du lisoir par exemple une platine 61 adjacente, par exemple solidaire du châssis, mobile ou non avec lui ou par rapport à lui. Sur la variante représentée, on a choisi un support solidaire de la crapaudine.According to the variant represented, this is two independent metal blades of torsion 55 and 56 of which respectively one of the ends 57 and 58 is attached to one end of the backing plate and support and whose other end respectively 59 and 60 is mounted on a stand independent of the example an adjacent plate 61, for example solidaire chassis, mobile or not with him or with respect to him. On the variant shown, we chose a solidarity support of the crapaudine.

Il importe que le support sur lequel sont fixées les extrémités des lames métalliques de torsion ne soit pas animé de mouvements conjugués avec ceux de l'articulation portée par l'appui flottant.It is important that the medium on which are fixed the ends of the metal torsion blades is not animated by movements combined with those of the articulation carried by the floating support.

Ces lames de torsion 55 et 56 constituent une liaison de jumelage entre chacune des deux extrémités de la plaque d'appui et de support 20 d'un même appui flottant. Elles constituent en même temps et à chaque fois une liaison individuelle à résistance de torsion à un point fixe voisin sur la platine commune 61.These torsion blades 55 and 56 constitute a twinning link between each of the two ends of the support and support plate 20 of the same support floating. They constitute at the same time and at each times an individual torsion-resistance link to a neighboring fixed point on the common plate 61.

Ces lames de torsion jumelées imposent une résistance mécanique pour réduire voire annuler l'effort de basculement transmis par l'articulation de pivotement portée par la plaque d'appui et de support 20.These twin torsion blades impose a mechanical resistance to reduce or cancel the tipping force transmitted by the articulation of pivoting carried by the support and support plate 20.

Cette liaison assure également une résistance supplémentaire et une meilleure raideur à la suspension élastique lui évitant ainsi des mouvements latéraux sources d'instabilité et de déformation.This link also provides resistance additional and better stiffness to the suspension elastic thus avoiding lateral movements sources of instability and deformation.

Elle assure aussi un effet supplémentaire d'amortissement des mouvements qui vient s'ajouter à la dégradation de l'énergie par friction.It also provides an additional effect of damping movements which is added to the degradation of energy by friction.

Selon une variante, on peut utiliser la même lame de torsion pour les deux extrémités de la plaque d'appui et de support 20 du même appui flottant. Cette lame commune aurait alors une extrémité conformée en fourche.According to one variant, the same torsion blade for both ends of the plate support and support 20 of the same floating support. This common blade would then have a consistent end in fork.

Selon une autre variante, on utilise la même lame pour relier les deux extrémités correspondantes de la plaque d'appui et de support 20 des deux appuis flottants homologues. De ce fait, une seule lame réunit à chaque fois les deux extrémités correspondantes des appuis flottants, cette lame étant fixée dans sa partie médiane à un support, par exemple la platine 61.According to another variant, the same blade to connect the two corresponding ends of the support and support plate 20 of the two supports floating counterparts. As a result, only one blade meets each time the two corresponding ends of floating supports, this blade being fixed in its part median to a support, for example platinum 61.

On peut aussi utiliser une seule lame commune dont chacune des deux extrémités est conformée en fourche pour former le moyen anti-basculement des deux appuis flottantsOne can also use a single common blade each of whose two ends is shaped in fork to form the anti-tilt means of both floating supports

Le dispositif d'appui flottant avec le moyen anti-basculement selon l'invention fonctionne de la façon suivante.The floating support device with the means anti-tilt according to the invention operates from the following way.

Lorsque l'impulsion initiale en mouvement de l'extrémité concernée est une tendance au basculement longitudinal et/ou transversal, la pression consécutive sur l'une des extrémités de la plaque d'appui et de support 20 est immédiatement neutralisée en général totalement par les couples inverses que lui oppose(nt) la ou les lame(s) de torsion sollicitée(s).When the initial pulse in motion of the affected end is a tipping tendency longitudinal and / or transversal, the consecutive pressure on one end of the support plate and support 20 is immediately neutralized in general totally by the opposite pairs that opposes him (it) the requested torsion blade (s).

Ces couples opposés étant fonction de l'effort de basculement, ils diminuent puis s'annulent lorsque cet effort de basculement décroít vers zéro permettant ainsi un meilleur glissement de friction.These opposing pairs being a function of the tipping effort, they diminish then cancel each other when this tipping effort decreases to zero thus allowing a better slip of friction.

Les lames de torsion présentant également une résistance aux efforts notamment longitudinaux, augmentent l'amortissement des mouvements et ainsi la dégradation de l'énergie s'en trouve encore améliorée.The torsion blades also having a resistance to particularly longitudinal forces, increase the damping of movements and so the energy degradation is further improved.

Le présent perfectionnement s'applique également aux moyens représentés sur les figures 10 à 19 et décrits ci-dessus.This improvement applies also to the means shown in FIGS. 19 and described above.

Le ou les moyens anti-basculement se réalise(nt) à chaque fois sous la forme de deux lames de torsion, de préférence métalliques à deux branches indépendantes 62 et 63 comme représenté sur la figure 10, mais dont les extrémités dirigées vers l'articulation centrale commune 13 sont fixées sur un même support 64 par exemple solidaire de la crapaudine. Ces lames constituent de chaque côté un ensemble anti-basculement dont la forme de profil est celle de deux U couchés et accolés par une branche commune 65 et dont les extrémités des deux autres branches 66 et 67 sont fixées de chaque côté à la plaque d'appui et de support 20 correspondante.The anti-tipping means realize (s) each time in the form of two blades torsion, preferably two-branched metal 62 and 63 as shown in FIG. 10, but whose ends directed towards the common central joint 13 are fixed on a same support 64 for example integral with the thrust. These blades constitute on each side an anti-tilt assembly whose profile shape is that of two U lying and joined together by a common branch 65 and the ends of the other two branches 66 and 67 are fixed on each side to the support and support plate Corresponding.

Bien entendu d'autres réalisations entrant dans le même concept inventif sont possibles, notamment celles à moyens équivalents par ressorts autres que des lames de torsion.Of course other achievements coming in in the same inventive concept are possible, especially those with equivalent means by means other than torsion blades.
