Abstract

The floating lateral support for two successive wagon structures (1,2), articulated on a single bogie, comprises a bogie suspension unit on each side of the bogie central articulation. On the suspension unit a support (21) is mounted by means of a support bearing plate (20). The support has an articulation providing a displacement between the bearing plate and an end toe (24) representing a first functional displacement. The other end toe (25) has an intermittent mechanical connection by means of a frictional support contact between the lower and upper face of the bearing support plate representing another functional displacement between a support position and a raised position.

Description

L'invention concerne un système d'articulation entre deux structures wagon successives reposant sur un même bogie et comprenant des appuis d'articulation latéraux flottants entre les extrémités opposées des deux structures wagon.The invention relates to a system of articulation between two structures wagon on the same bogie and including floating lateral articulation supports between the opposite ends of the two wagon structures.

La présente invention se situe dans le domaine ferroviaire et plus particulièrement dans le domaine ferroviaire du transport de véhicules routiers sur wagons.The present invention lies in the railway sector and more particularly in the road transport sector of road vehicles on wagons.

Elle se rapporte plus particulièrement à un appui d'articulation flottant pour les extrémités opposées de deux structures wagon articulées entre elles par une articulation centrale sur un même bogie.It relates more particularly to a floating hinge support for the ends opposing two wagon structures articulated between they by a central articulation on the same bogie.

Il existe dans le domaine des transports ferroviaires des constitutions de train formés par la succession de structures wagon dont les extrémités opposées reposent sur un même bogie. Celles-ci sont articulées entre elles en général par une articulation centrale commune qui repose sur le châssis du bogie par un support articulé appelé crapaudine. Cette dernière, sous la forme d'une articulation sphérique, assure la liaison d'articulation entre les extrémités des structures wagon réunies entre elles et la base-châssis du bogie.It exists in the field of transport railway constitutions formed by the succession of wagon structures whose ends opposed are based on the same bogie. These are articulated together in general by an articulation common plant that is based on the bogie frame an articulated support called crapaudine. The latter, in the form of a spherical joint, ensures the articulation link between the ends of the wagon structures joined together and the chassis base of the bogie.

Cet appui ponctuel central laisse un débattement de basculement latéral et longitudinal.This central point support leaves a Lateral and longitudinal tilting clearance

Pour des raisons de stabilité, cet appui central est complété par un appui latéral de chaque côté dont le débattement est limité par des butées internes au dispositif.For reasons of stability, this support central is complemented by lateral support from each side whose travel is limited by stops internal to the device.

Ces appuis latéraux montés de chaque côté de l'articulation centrale, sont appelés traditionnellement lisoirs. Les mouvements de la structure wagon provenant du roulage et des efforts dynamiques sont amortis et limités par ces appuis latéraux.These side supports mounted on each side of the central articulation, are called traditionally slips. The movements of the wagon structure from rolling and efforts dynamics are amortized and limited by these supports side.

De façon classique, les lisoirs sont formés chacun d'une platine d'appui dynamique, celle-ci étant montée sur une embase mobile par rapport au châssis et suspendue sur celui-ci par deux ressorts. Les efforts en appui s'exerçant sur le lisoir vont comprimer les ressorts et l'embase se déplace dans un mouvement amorti.Typically, the flasks are formed each of a dynamic support plate, the latter being mounted on a mobile base relative to the chassis and suspended on it by two springs. The efforts in support acting on the light will compress the springs and the base moves in a movement amortized.

Il en est de même que l'effort vienne d'une extrémité ou de l'autre. Ainsi, les amplitudes des débattements des extrémités au niveau de l'appui même peu importantes se traduisent à l'extrémité haute de la charge transportée par des déplacements importants pouvant faire sortir la charge transportée du gabarit ferroviaire imposé.It is the same that the effort comes from a end or the other. Thus, the amplitudes of deflections of the ends at the level of the support itself unimportant translates to the high end of the load transported by large displacements able to remove the load transported from the template imposed railway.

On connaít une solution antérieure selon laquelle l'entraínement en mouvement de roulis et de tangage d'une extrémité d'une structure wagon par l'autre est réduit en ce que l'une appuie sur l'autre avec un certain jeu dans la transmission des efforts. Ainsi, chacune peut débattre indépendamment l'une de l'autre jusqu'à rattraper le jeu introduit dans leur liaison technique. Il ne s'agit en réalité que d'un effet retard et au bout d'un certain temps les lisoirs sont sollicités car les mouvements d'une extrémité entraínent l'autre dans sa course.We know an earlier solution according to which drive in motion roll and pitching one end of a wagon structure by the other is reduced in that one presses on the other with some game in the transmission of efforts. Thus, each can independently debate one of the other up to catch up with the game introduced in their technical liaison. It is really only a question of effect delay and after a while the flasks are solicited because the movements of one end drive the other in his race.

Cette solution n'apporte qu'une faible amélioration car le jeu ne peut être important pour éviter les à-coups et au-delà de ce jeu tous les inconvénients réapparaissent. La présence de ce jeu accroít le risque de sortie du gabarit ferroviaire de la partie haute de la charge transportée.This solution brings only a weak improvement because the game can not be important for avoid jolts and beyond this game all the disadvantages reappear. The presence of this game increases the risk of leaving the rail gauge the upper part of the load transported.

Une connexion entre deux structures wagon successives reposant sur un même bogie et présentant une articulation centrale commune et deux appuis latéraux flottants est suggérée par le document US-A-2,104,840 en vue d'assurer une certaine stabilité.A connection between two wagon structures successive stages based on the same bogie and a common central joint and two supports floating sides is suggested by the document US-A-2,104,840 to provide some stability.

Les moyens utilisés sont du type à roulement et ne peuvent donc pas présenter un amortissement lié à la friction car la surface de roulement doit être plane et lisse.The means used are of rolling type and therefore can not have a depreciation related to friction because the running surface must be flat and smooth.

Cette solution générale est celle décrite dans le préambule de la revendication principale.This general solution is that described in the preamble of the main claim.

La présente invention vise le transport ferroviaire de charges d'une hauteur maximale dans le cas notamment de remorques et de semi-remorques tout en restant dans le gabarit ferroviaire quels que soient les mouvements des structures wagon notamment lors du roulage.The present invention relates to the transport rail of loads of maximum height in the in particular trailers and semi-trailers while remaining in the rail gauge whatever the movements of the wagon structures, especially during the rolling.

La présente invention vise aussi à éviter un trop grand jeu dans les articulations pour garantir une fiabilité et à procurer des réalisations abordables techniquement et économiquement.The present invention also aims at avoiding a too much play in the joints to guarantee a reliability and affordable achievements technically and economically.

En sollicitant moins les articulations et les structures, on améliore la fiabilité. En allégeant les structures on réduit le coût en matière et en main d'oeuvre ainsi que le poids mort.By less stress on the joints and structures, we improve reliability. By lightening structures we reduce the cost in matter and in hand as well as the dead weight.

L'invention a pour but de remédier aux différents inconvénients précités et procure plusieurs avantages importants.The aim of the invention is to remedy various disadvantages mentioned above and provides several important benefits.

A cet effet, le système d'articulation présente un appui latéral flottant pour deux structures wagon successives articulées entre elles sur un même bogie ferroviaire par une articulation centrale commune, appui utilisé de chaque côté du bogie commun et de part et d'autre de l'articulation centrale commune comprenant un ensemble de suspension élastique portant une garniture de friction, une première patte d'extrémité d'une structure wagon et une deuxième patte d'extrémité de la structure wagon suivante, les pattes d'extrémité étant réunies par une articulation avec débattement portée par un support d'articulation monté sur une plaque d'appui et de support, elle même portée par et déplaçable sur l'ensemble de suspension et par rapport à celui-ci et par une liaison pouvant être interrompue formée d'une zone d'appui glissant de friction sur la plaque d'appui et de support et d'un contact ouvert ou fermé entre la zone d'appui glissant de friction et la deuxième patte d'extrémité.For this purpose, the articulation system has a support floating side for two successive wagon structures articulated together on the same railway bogie by a common central joint, used support of each side of the common truck and on both sides of the common central articulation comprising a set of elastic suspension with a filling of friction, a first end leg of a wagon structure and a second end tab of the next wagon structure, the end legs being united by a joint with deflection by a hinge support mounted on a plate support and support, it is itself worn by and movable on the suspension assembly and relative to this one and by a link that can be interrupted formed of a sliding friction bearing zone on the support plate and support and an open contact or closed between the slip sliding friction zone and the second end tab.

Cette constitution permet de procurer divers avantages importants.This constitution makes it possible to provide various important benefits.

L'indépendance des mouvements dans la limite des jeux prévus assure une grande fiabilité de fonctionnement et une grande longévité du matériel en raison de l'absence de sollicitation mécanique de l'une des structures wagon par l'autre.Independence of movements within the limit scheduled games ensures high reliability of operation and a long service life of the equipment because of the lack of mechanical stress on one wagon structures by the other.

La construction peut s'alléger par des gains de matière et des simplifications de réalisation diminuant le temps de montage et plus généralement de construction.Construction can be lightened by gains of material and simplifications of realization decreasing the assembly time and more generally construction.

Grâce à l'invention, par la limitation de l'interaction et des jeux verticaux des structures wagon entre elles, on peut transporter des charges de hauteur maximale dans la limite du gabarit ferroviaire.Thanks to the invention, by the limitation of interaction and vertical games structures wagon between them, one can carry loads of maximum height within the limit of the railway gauge.

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 commune 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.The crapaudine 9 and the central articulation common 13 form a composite joint to three degrees of freedom allowing all inclinations related to rolling movements and among them the roll and pitch movements.

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 de façon générale, 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 de bogie appelé communément dans le langage technique lisoir. Une plaque d'appui et de support 20 est en contact de frottement avec la face supérieure ou la garniture de l'embase 18.These discontinuous lateral bonds 14 and 15 are constituted in a general way, according to this invention of the following means. A mobile base 18 vertically is mounted on a device suspension with stops forming a suspension assembly 19 of bogie commonly called in the language technical readout. A support plate and support 20 is in frictional contact with the upper face or the lining of the base 18.

Selon la première variante de l'invention, se trouve solidaire de cette embase 18 ou monté sur celle-ci ou en relation avec elle un support 21 d'articulation recevant une articulation 22 par exemple une articulation du type à axe de pivotement 23.According to the first variant of the invention, is secured to this base 18 or mounted on it or in connection with it a support 21 articulation receiving a joint 22 for example pivot-type articulation 23.

Les extrémités 3 et 4 des structures wagons 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 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 centrale commune 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 slider and on the other side a link to occasional or closed discontinuity depending on whether 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 common central articulation 13.

La patte double d'extrémité 24 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 24 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 de bogie 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 of bogie consisting of at least two compression 32 and 33 on the end of which she rests by its end portions to form the suspension assembly 19. The springs 32 and 33 of the suspension are guided by inner parts 34 and 35 along which they move in a compression-loosening motion corresponding to their suspension work.

Ces pièces intérieures 34 et 35 représentées sur les figures 5 à 8 jouent également le rôle de guidage et de butée. 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 in FIGS. 5 to 8 also play the role of guiding and abutment. 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 intercalaire 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 of the base 18 furnished with a piece insert and friction interlayers 36. The plate support and support 20 can be carried out according to different technological variants for example in one composite structure formed of several plates superimposed for example three as shown on 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 21 porte articulation. Cette zone de portée-friction 37 est garnie autour du support 21 d'articulation mais à distance de celui-ci, d'un insert de friction 38 d'une seule pièce 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 support 21 door articulation. This range of friction 37 is lined around the support 21 articulation but at a distance from it, an insert of friction 38 of a single piece in the form of a frame 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 21 d'articulation 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 un revêtement, en un matériau à fort coefficient de frottement permettant de dégrader une partie importante de l'énergie mécanique 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 a coating made of a material with a high coefficient of friction to degrade an important part mechanical energy during support work and slip-friction displacement of the sole 39 or 40 of each underside of the elements 26 and 26a component the double end tab 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 variante représentée, ce support 21 d'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 d'articulation comporte dans sa partie supérieure un logement de déplacement 42 pour l'axe de pivotement 23 de l'articulation 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 23 de l'articulation de pivotement 22 peut se déplacer le long de ce logement 42 entre une position haute et une position basse et inversement. Sur cet axe de pivotement sont montées les extrémités latérales de la patte à fourche 24. Le logement de déplacement 42 présente en vue du déplacement de l'axe 23 de l'articulation de pivotement 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 variant shown, this support 21 articulation is shaped as a vertical stirrup and present in the form of a mechanical block formed by example of two flank pieces assembled by a pawn 41 to the support and support plate 20. The support 21 articulation has in its upper part a displacement housing 42 for the pivot axis 23 of the pivot joint 22. This housing 42 is formed of a lower transverse cylindrical cavity extending upwards by two open branches or twinned by a transverse safety connection. The pivot axis 23 of the pivot joint 22 can move along this housing 42 between a high position and a low position and vice versa. On this pivot axis are mounted the ends side of the fork leg. displacement 42 present for the displacement of the axis 23 of the pivot joint 22 a section transverse of substantially oblong open form upward but preferably to exit condemned by the transverse safety connection for example by transverse bolts (not shown).

La mobilité verticale de l'axe de pivotement 23 de l'articulation 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 double 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 d'extrémité 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 23 qui, dans ce cas est fixe. Bien entendu, tous les cas de combinaison de ces mobilités sont possibles.Vertical mobility of the pivot axis 23 of the pivot joint 22 between a low position and a high position along his displacement housing 42 represents the travel vertical 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 double end tab 25 and the support plate and support 20. This latitude of movement corresponds to the race between the support and the raised position of the double end tab 25 as will be described below in the explanation of the operation. Mobility is also used reverse that is to say that of the hinge support 21 relative to the pivot axis 23 which, in this case is fixed. Of course, all cases of combination of these mobilities are possible.

Selon une variante particulière de cette fonction, on peut réaliser le support 21 d'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 d'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 d'articulation 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 de pivotement 23 le long de son logement n'est plus totalement nécessaire car celui-ci est assuré par le déplacement de son support 21 porte articulation.According to a particular variant of this function, one can realize the articulation support 21 movable relative to the plate 20 support and support to achieve total independence of movement between the two ends of the wagon structures. According to this variant, the articulation support 21 thus crosses the support plate 20 and support for directly exert his pushing force on and against the friction piece 36 of the suspension assembly 19 forming a lip. For this purpose, this support 21 hinge can be slidably mounted in a obviously crossing in the center of the support plate 20 and support (not shown). A movement guided by grooves, grooves or other means would allow a good functioning and a correct presentation support of the base of this support 21. Of course, in this case, the displacement of the pivot axis 23 the along its housing is no longer completely necessary because it is ensured by the displacement of its support 21 door articulation.

On peut également envisager une variante selon laquelle le support 21 d'articulation est aussi 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 21 porte d'articulation et la plaque 20 par un intervalle avant contact.It is also possible to envisage a variant according to which the articulation support 21 is also movable relative to the support plate and support 20, but acts indirectly on the lip and this to through this plate 20. In this case, it is possible to provide additional travel between the support 21 hinge door and the plate 20 by a interval 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 9.The extreme positions are represented on Figures 5 to 9.

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 d'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 23 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 hinge up to 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 23 reaches the bottom abutment housing 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 23 est prévu pour tourner dans son logement lors des basculements de tangage.The pivot axis 23 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 23 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 23 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 de la présente invention 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 24 et la plaque 20 d'appui et de support lors des mouvements dus au roulage.The general interest of the present invention lies in the presence of at least two deflections one at the articulation support 21 and the other between the end tab 24 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 représentée sur les figures 10 à 19 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 represented on the Figures 10 to 19 have 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 more 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 figure 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 11 and 12, the end central leg 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 outer 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.
