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

APPUI LATERAL FLOTTANT POUR DEUX STRUCTURES WAGON SUCCESSIVES ARTICULEES SUR UN MEME BOGIE FERROVIAIREFLOATING SIDE SUPPORT FOR TWO SUCCESSIVE WAGON STRUCTURES ARTICULATED ON THE SAME RAILWAY BOGIE
Appui d'articulation latéral flottant entre 5 les extrémités opposées de deux structures wagon articulées entre elles sur un même bogie- La présente invention se situe dans le domaine ferroviaire et plus particulièrement dans le domaine ferroviaire du transport de véhicules routiers 10 sur wagons.Lateral articulation support floating between 5 the opposite ends of two wagon structures hinged together on the same bogie.
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 articulation support for the opposite ends of two wagon structures articulated together by a central articulation on the same bogie.
15 II 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 articulation15 In the field of rail transport, there are train constitutions formed by the succession of wagon structures whose opposite ends rest on the same bogie. These are generally hinged together by an articulation
20 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-châssis20 common central unit which rests on the bogie chassis by an articulated support called a crapaudine. The latter, in the form of a spherical articulation, ensures the articulation connection between the ends of the wagon structures joined together and the chassis base
25 du bogie.25 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 movement.
Pour des raisons de stabilité, cet appui central est complété par un appui latéral de chaque 30 côté dont le débattement est limité par des butées internes au dispositif.For reasons of stability, this central support is completed by a lateral support on each side, the movement of which 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 lateral supports mounted on each side of the central articulation, are traditionally called reading rooms. The movements of the wagon structure from rolling and dynamic forces are absorbed and limited by these lateral supports.
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 .Conventionally, the sideboards are each formed of a dynamic support plate, the latter being mounted on a base movable relative to the frame and suspended on the latter by two springs. The pressing forces exerted on the reading frame will compress the springs and the base moves in a damped movement.
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 1 ' extrémité haute de la charge transportée par des déplacements importants pouvant faire sortir la charge transportée du gabarit ferroviaire imposé. On connaît une solution antérieure selon laquelle l'entraînement 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 entraînent l'autre dans sa course.It is the same as the effort comes from one end or the other. Thus, the amplitudes of the deflections of the ends at the level of the support, even small, are reflected at the upper end of the load transported by large displacements which can cause the transported load to come out of the imposed railway gauge. A prior solution is known according to which the drive in rolling and pitching movement of one end of a wagon structure by the other is reduced in that one presses on the other with a certain play in the transmission some efforts. Thus, each can debate independently of one another to catch up with the game introduced in their technical connection. In reality, this is only a delay effect and after a certain time the reading boards are used because the movements of one end lead the other in its course.
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 accroît le risque de sortie du gabarit ferroviaire de la partie haute de la charge transportée. 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.This solution brings only a small improvement because the game cannot be important for avoid jolts and beyond this game all the disadvantages reappear. The presence of this clearance increases the risk of the rail gauge leaving the upper part of the load transported. The present invention relates to the rail transport of loads of a maximum height in the case in particular of trailers and semi-trailers while remaining within the railway gauge whatever the movements of the wagon structures in particular during taxiing.
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. 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.The present invention also aims to avoid too much play in the joints to guarantee reliability and to provide affordable and technically and economically achievable products. By putting less stress on joints and structures, reliability is improved. By reducing the structures, the cost of material and labor is reduced, as well as the dead weight.
L ' invention a pour but de remédier aux différents inconvénients précités et procure plusieurs avantages importants .The object of the invention is to remedy the various aforementioned drawbacks and provides several important advantages.
A cet effet, elle se rapporte à 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 1 ' 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 1 ' 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.To this end, it relates to a floating lateral support for two successive wagon structures articulated together on the same railway bogie by a common central articulation, support used on each side of the common bogie and on either side of the articulation common central unit comprising an elastic suspension assembly carrying a friction lining, a first end leg of a wagon structure and a second end leg of the following wagon structure, the end legs being joined by a joint with movement scope by an articulation support mounted on a support and support plate, itself carried by and movable on the suspension assembly and with respect to it and by a link which can be interrupted formed by a zone of sliding friction support on the support and support plate and of an open or closed contact between the friction sliding support zone and the second end tab.
Cette constitution permet de procurer divers avantages importants.This constitution provides various important advantages.
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.The independence of movements within the limit of the games provided ensures high operating reliability and a long service life of the equipment due to the absence of mechanical stress from one of the 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. 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.The construction can be lightened by material savings and simplifications of construction reducing the assembly time and more generally of construction. Thanks to the invention, by limiting the interaction and the vertical play of the wagon structures between them, it is possible to transport loads of maximum height within the limit of the railway gauge.

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 emboîtée dans cette coque réceptrice. La crapaudine 9 est reliée à une articulation centrale commune de pivotement 13 avec débattement en basculement latéral constituant 1 ' articulation principale par laquelle les extrémités 3 et 4 sont reliées entre elles à pivotement. 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 present invention applies to two successive wagon structures 1 and 2 from left to right in FIG. 2, the opposite ends 3 and 4 of which are articulated on the same bogie 5 having two axles 6 and 7 and a chassis 8. This chassis 8 carries a plug 9 with a semi-spherical body 10 formed of two complementary articulation parts including a receiving spherical shell 11 and a sphere 12 fitted into this receiving shell. The clamp 9 is connected to a common central pivot articulation 13 with lateral tilting movement constituting the main articulation by which the ends 3 and 4 are pivotally connected to one another. The basket 9 and the common central articulation 13 form a composite articulation with three degrees of freedom allowing all the inclinations related to the rolling movements and among them the rolling and pitching 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.The opposite ends 3 and 4 of the wagon structures are connected to each other on each side by a specific lateral connection with occasional discontinuity 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 the successive wagon structures 1 and 2 in their movements, there are two movable lateral supports 16 and 17 on each of which carries an end element of one of the discontinuous lateral connections 14 and 15 respectively.
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 side connections 14 and 15 generally consist of the following means, according to the present invention. A vertically movable base 18 is mounted on a suspension device with stops forming a bogie suspension assembly 19 commonly known in the technical language as a reader. A support and support plate 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 integral with this base 18 or mounted thereon or in relation to it a hinge support 21 receiving a hinge 22, for example a hinge of the type with pivot axis 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 1 • 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 comprise, at the level of each discontinuous lateral connection 14 and 15, extensions in the form of end tabs carrying out at the level of each discontinuous lateral connection on one side a junction with the edge panel and on the other side a bond to occasional or closed discontinuity depending on whether the end of the corresponding end tab is in the raised position or in contact with support. These end tabs, present on each side, are of two types: a forked end tab 24 for the end 3 and a double end tab 25 for 1 • end 4 facing each other of the common central joint 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 by two elements 26 and 26a, at least one of which, but preferably both, have a substantially horizontal underside 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 articulation support according to the invention has 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. 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 in the form of a plate is slidably mounted vertically by its central part 27, for example in cylindrical projection to come to guide sliding in a housing 28 for example cylindrical formed in a fixed support 29 integral with the chassis 8 of the bogie. Guidance is improved by a central stud 30 slidingly engaging in a central cavity 31. The base 18 is mounted on a bogie suspension made up of at least two compression springs 32 and 33 on the end of which it rests by its end parts to form the suspension assembly 19. The springs 32 and 33 of the suspension are guided by internal parts 34 and 35 along which they move in a compression-relaxation movement 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 Figures 5 to 8 also play the role of guide and stop. They will be called thereafter guide and stop parts. In fact, the underside of the base 18 comes to the end of its travel, in abutment contact with the front face of these abutment and guide parts during movements of large amplitude corresponding to the movement of the base 18 making it possible to dampen 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. 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.A distinction is then made between the support and support plate 20 mounted as a friction support on the upper face of the base 18 provided with an intermediate support and friction piece 36. The support and support plate 20 can be made according to different technological variants for example in a composite structure formed of several superimposed plates, for example three as shown in the figures or any other constitution. The support and support plate 20 has on its upper face a friction-carrying zone 37 extending for example on either side and around the support 21 articulation carrier. This friction-carrying zone 37 is lined around the articulation support 21 but at a distance therefrom, from a friction insert 38 in one piece in the form of a frame or in several pieces on which each of the corresponding soles 39 and 40 with which the underside of elements 26 and 26a of the double end tab 25 are equipped respectively.
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 1* insert de friction 38 de la zone de portée-friction 37 en regard.The frictional insert 38 in the frame is placed for example at a distance by its internal perimeter from the edges of the articulation support 21 and slightly recessed downwards relative to the plane of the upper face of the support and support plate 20. It embeds the friction-carrying zone 37 and is produced in the form of a solid plate or a coating, in a material with a high coefficient of friction making it possible to degrade a significant part of the mechanical energy during the work of 'support and displacement in sliding-friction of the sole 39 or 40 of each underside of the elements 26 and 26a composing the double end tab 25 and 1 * friction insert 38 of the bearing-friction 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 carrier.
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 articulation support 21 is shaped as a vertical stirrup and is in the form of a mechanical block formed for example of two flank pieces assembled by a pin 41 to the support and support plate 20 The articulation support 21 has in its upper part a displacement housing 42 for the pivot axis 23 of the pivot articulation 22. This housing 42 is formed by a lower transverse cylindrical cavity extending upwards by two branches open or paired by a transverse safety link. 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 lateral ends of the fork dropout 24. The displacement housing 42 presents for the displacement of the axis 23 of the pivot joint 22 a cross section of substantially oblong shape open upwards but preferably with an outlet locked by the transverse safety link, 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.The vertical mobility of the pivot axis 23 of the pivot joint 22 between a low position and a high position along its displacement housing 42 represents the vertical clearance used as freedom of movement in conjunction with the floating mounting of the plate support and support 20 and the latitude of movement existing between the double end tab 25 and the support and support plate 20. This latitude of movement corresponds to the travel between the support and the raised position of the double end tab 25 as will be described below in the explanation of operation. Reverse mobility is also used, that is to say that of the articulation support 21 with respect 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, it is possible to produce the support 21 for movable articulation with respect to the support and support plate 20 to obtain complete independence of movement between one and the other ends of the wagon structures. According to this variant, the articulation support 21 thus crosses the support and support plate 20 to directly exert its pushing force on and against the friction piece 36 of the suspension assembly 19 forming a reading stand. To this end, this support 21 articulation can be slidably mounted in a recess through the center of the support plate 20 and support (not shown). A movement guided by grooves, grooves or other means would allow proper operation and a correct presentation of support of the base of this support 21. Of course, in this case, the movement of the pivot axis 23 along its housing is no longer completely necessary because it is provided by the displacement of its support 21 hinge door.
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 and support plate 20, but acts indirectly on the bookcase and this 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 an 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. Les positions extrêmes sont représentées sur les figures 5 à 9.In taxiing, according to the movements coming from a wagon structure or from the other or from one side or the other of the same wagon structure, the floating lateral supports will work by moving in one direction or another by example from bottom to top or vice versa. The extreme positions are shown in 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 thrust coming from the wagon structure 1 on the left (FIGS. 5 and 6), during a downward tilting, the fork tab 24 at the end will press on the suspension assembly 19 or side bar via the articulation support 21 until compensation or stop contact by the compression springs 32 and 33 of the suspension assembly 19 on the internal abutment and guide parts 34 and 35. In fact, as soon as the pivot axis 23 comes into abutment at the bottom of the housing 42, the suspension assembly sags in a damped movement under the thrust of the corresponding end 3 of the wagon structure 1 due to the work of the suspension springs.
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 also has a horizontal component, the support and support plate 20 rips by sliding friction on the intermediate support and friction part 36.
L'axe de pivotement 23 est prévu pour tourner dans son logement lors des basculements de tangage. 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. Toute composition des mouvements ci-dessus est possible en raison de l'absence de liaison mécanique fonctionnelle entre les pattes 24 et 25.The pivot axis 23 is provided to rotate in its housing during pitch tilting. Conversely, in the case of FIGS. 7 and 8, the double support leg 25 can be pushed downwards and it is then the two elements 26 and 26a of the double support leg 25 which collapse the suspension assembly 19 by pressing their lining plates 39 and 40 on the friction-carrying zone 37. The suspension assembly 19 descends with the support 21 articulation carrier, leaving the pivot axis 23 in its position in its housing 42 thanks to freedom of movement along this oblong section housing. Any composition of the above movements is possible due to the absence of a functional mechanical connection 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.The movements of the end of a wagon structure have thus been made independent of those of the end of the following wagon structure within the limit of maximum travel 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 of sliding articulation independently of the support and support plate 20, independence is total. Each end of each wagon structure can move and act alone on the friction piece 36 of the reader.
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 level of the articulation support 21 and the other between the end tab 24 and the support and support plate 20. 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 the extremities, these deflections are not necessarily simultaneous. They offer in all cases of normal use of wagon structures during taxiing, an idle stroke making it possible to avoid the transmission of movements at the other end, knowing that in addition, these are damped by the springs of suspension assembly 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 shown in Figures 10 to 19 has the same general functions and equivalent means. The same or almost identical elements will have the same reference numbers.
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.In this second variant, an attempt has been made to descend the horizontal pivot axis referenced 23 from the pivot articulation 22 as much as possible towards the bookcase so as to minimize the tilting torque. Indeed, friction has the effect of creating a couple and the more the friction part is distant from the pivot axis, the more it tends to brace. This effect should be made minimal for proper functioning, to reduce wear and to avoid torques prejudicial to the rolling stability of the 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 movable vertically mounted on a suspension device with stops forming the suspension assembly 19 of bogie commonly called in technical language reading board. A support and support plate 20 in frictional contact with the upper face or the lining of the base 18 has a hinge support 43 receiving a special hinge 44 for pivoting about a horizontal axis and vertical translation. A multidirectional articulation, for example of the ball-and-socket type or equivalent shape, may also be suitable although, apart from clearance clearance, only the vertical translational and pivoting movements about a horizontal axis passing through the 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 1 ' autre patte d'extrémité à savoir la patte centrale d'extrémité 48 qui se trouve montée en prise sur l'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.The end tabs are almost identical in shape for one of them 45 with two branches 46 and 47 corresponding to the double tab 25, but different at its end for the other end tab, namely the central end tab 48 which is engaged on the articulation 44. With particular reference to FIGS. 11 and 12, the central end tab 48 ends with an end looking downwards and having a cavity forming a housing 49 for the articulation 44. The latter relates to the articulation support 43 produced in the form of a block 50, for example parallelepiped. On this articulation support block is mounted a receiving element 51 by straight example as shown in Figure 12 cooperating with a stud 52 fitted to the bottom of the housing 49 to form a safety assembly for the operation of the joint. This articulation support 43 produced in the form of the block 50 comprises on a part of its lateral surface a bearing lining 53 with a convex outer face. This bearing lining 53 is located during operation opposite a fur 54 attached to the lateral surface of the housing 49. This fur 54 has a flat outer face which reduces the surface in contact with the outer face of the lining 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 should be understood that here the articulation support 43 is the support block 50 on the support and support plate 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 be otherwise connected or related to it. In particular, this articulation support can be mounted mobile relative 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 shown and used to form the articulation 44 carried by the articulation support 43 were chosen because of the small amplitudes of movement generated during 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. 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.By examining the means described above, it can be concluded that the general function of uncoupling the movements of the end legs is fulfilled in the same way in accordance with the invention. It is indeed a variant coming within the scope of the present invention. With regard to the operation, reference will be made for the main phases to the detailed explanation above already described for the first variant. The particularity of the operation of this second variant comes from the replacement of the pivot joint 22 with vertical displacement of its axis 23 by a specific joint 44. The operation of this specific joint 44 makes it possible to complete the explanation of the overall operation.
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 1 ' invention. When taking a curve or during another fact generating movement at the end tabs, the double end tab 45 acts by sliding support in the same way as that of the first variant. On the other hand, the central end tab 48 directly transmits the movement which animates it to the articulation 44. This makes it possible to absorb the types of deviations and displacements generated whether they are vertical, or inclination around of a horizontal pivot axis and of damping them by friction on the friction lining (s) and obtaining the uncoupling which is the main object of the invention.
