Description

BOITE D'ESSIEU SUR LAQUELLE PREND APPUI AU MOINS UN ENSEMBLE ELASTIQUE L'invention se rapporte à une boite d'essieu sur laquelle prend appui au moins un ensemble élastique entrant dans la réalisation d'une suspension d'un matériel ferroviaire tel un bogie ou un wagon. The invention relates to an axle box on which is supported at least one elastic assembly used in the production of a suspension of railway equipment such as a bogie or a wagon.
La suspension d'un véhicule à pour objet, d'une part, de répartir la charge statique du véhicule entre les différents points d'appui au sol et, d'autre part, d'amortir les efforts dynamiques produits notamment par les irrégularités de la surface d'appui.The purpose of suspending a vehicle is, on the one hand, to distribute the static load of the vehicle between the different ground support points and, on the other hand, to absorb the dynamic forces produced in particular by the irregularities of the support surface.
La suspension d'un véhicule ferroviaire comprend, généralement, au moins une paire d'ensembles élastiques situés de part et d'autre d'une boite d'essieu et qui à leur base sont chacun en appui sur une table d'appui dite généralement "palette" laquelle est solidaire de la boite d'essieu et qui à leur extrémité supérieure sont associés au moins indirectement au longeron du wagon ou d'un bogie.The suspension of a railway vehicle generally comprises at least one pair of elastic assemblies located on either side of an axle box and which at their base are each supported on a support table known as generally "pallet" which is integral with the axle box and which at their upper end are associated at least indirectly with the spar of the wagon or a bogie.
Classiquement, l'ensemble élastique est constitué de deux ressorts spirales dont l'un dit ressort de tare a un diamètre interne supérieur au diamètre externe du second ressort dit ressort de charge, de sorte que le ressort de charge puisse être logé dans le ressort de tare.Conventionally, the elastic assembly consists of two spiral springs, one of which says tare spring has an internal diameter greater than the external diameter of the second spring called load spring, so that the load spring can be accommodated in the spring tare.
Le ressort de tare reprend les efforts liés au poids à vide du wagon, tandis que le second devient actif au delà d'une charge prédéterminée qui s'ajoute au poids à vide du wagon. De manière classique, la table d'appui présente un dispositif de maintien de la base de l'ensemble élastique.The tare spring takes up the efforts linked to the empty weight of the wagon, while the second becomes active beyond a predetermined load which is added to the empty weight of the wagon. Conventionally, the support table has a device for holding the base of the elastic assembly.
Dans les solutions connues, le dispositif de maintien est fixé sur la face supérieure de la table d'appui et comprend des moyens de centrage des ressorts coaxiaux, la base de chacun de ces ressorts prenant appui sur un même plan.In known solutions, the holding device is fixed to the upper face of the support table and comprises means for centering the coaxial springs, the base of each of these springs resting on the same plane.
Dans ces solutions connues, les moyens de centrage comprennent un tourillon sur lequel la paroi interne du petit ressort se centre et une chemise qui, montée coaxialement au tourillon, a sa face externe qui coopère avec la paroi interne du gros ressort.In these known solutions, the centering means comprise a pin on which the internal wall of the small spring is centered and a jacket which, mounted coaxially with the pin, has its external face which cooperates with the internal wall of the large spring.
Pour avoir une hauteur de chargement importante, la distance qui sépare la table d'appui de la structure d'appui de l'extrémité supérieure de l'ensemble élastique est limitée.To have a significant loading height, the distance between the support table and the support structure of the upper end of the elastic assembly is limited.
On sait que dans un ressort la variation de longueur est proportionnelle à la raideur du ressort et à la variation de la force exercée sur le ressort.It is known that in a spring the variation in length is proportional to the stiffness of the spring and to the variation of the force exerted on the spring.
Dans le cas d'un ressort sollicité en compression, la variation de longueur admissible est liée à la distance séparant deux spires contigϋes et au nombre de spires.In the case of a spring stressed in compression, the variation in permissible length is linked to the distance separating two contiguous turns and to the number of turns.
De ce fait, pour une longueur donnée de ressort, si on souhaite augmenter la charge dynamique et si on souhaite contenir l'amplitude d'évolution de la longueur du ressort dans les limites disponibles, lors de la construction du ressort, il faut en augmenter la raideur, ce qui se traduit toutefois par une suspension plus dure qui devient alors plus agressive pour les rails.Therefore, for a given length of spring, if one wishes to increase the dynamic load and if one wishes to contain the amplitude of evolution of the length of the spring within the available limits, during the construction of the spring, it is necessary to increase it stiffness, which however results in a harder suspension which then becomes more aggressive for the rails.
Si on souhaite une suspension moins agressive et donc plus souple, il faut que la raideur du ressort soit plus faible ce qui entraine une variation de longueur du ressort, pour une force donnée, plus importante, d'où un risque de contact des spires si le ressort n'est pas suffisamment aéré, c'est à dire si les spires sont trop proches.If a less aggressive and therefore more flexible suspension is desired, the spring stiffness must be lower, which leads to a variation in the length of the spring, for a given force, greater, hence a risk of contacting the turns if the spring is not sufficiently ventilated, ie if the turns are too close.
Ceci impose donc de limiter le poids en charge des wagons ou leur vitesse de circulation pour éviter que les forces induites par les déformations de la voie de roulement soient trop importantes.This therefore requires limiting the laden weight of the wagons or their running speed to prevent the forces induced by the deformations of the track from being too great.
Un des résultats que l'invention vise à obtenir est une boite du type précité qui remédie à cet inconvénient et permet d'augmenter la charge à l'essieu et de limiter l'agressivité des matériels ferroviaires circulant sur les voies de chemin de fer.One of the results which the invention aims to obtain is a box of the aforementioned type which overcomes this drawback and makes it possible to increase the axle load and to limit the aggressiveness of the railway materials circulating on the railway tracks.
A cet effet, l'invention a pour objet une telle boite d'essieu présentant donc de part et d'autre de l'essieu une table d'appui encore appelée palette portant un dispositif de maintien pour la base d'un ensemble élastique d'une suspension, lequel ensemble élastique comprend lui même un premier ressort dit ressort de tare et un second ressort dit ressort de charge monté à l'intérieur du ressort de tare, cette boite d'essieu étant notamment caractérisée en ce que la table d'appui présente une cavité qui, sans diminuer notablement la résistance mécanique de ladite table, est apte à recevoir et loger sur une hauteur prédéterminée au moins le ressort de charge.To this end, the invention relates to such an axle box therefore having on either side of the axle a support table also called a pallet carrying a holding device for the base of an elastic assembly of a suspension, which elastic assembly itself comprises a first spring called a tare spring and a second spring called a load spring mounted on the inside the tare spring, this axle box being in particular characterized in that the support table has a cavity which, without significantly reducing the mechanical resistance of said table, is capable of receiving and accommodating at a predetermined height at least the load spring.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement : - figure 1 : une vue partielle d'une suspension d'un matériel ferroviaire,The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the appended drawing which schematically represents: - Figure 1: a partial view of a suspension of equipment rail,
- figure 2 : une vue partielle et en coupe d'une boite d'essieu.- Figure 2: a partial sectional view of an axle box.
En se reportant au dessin on voit que la suspension du véhicule ferroviaire comprend un essieu dont les extrémités sont guidées en rotation dans une boite d'essieu 1 associée au moins indirectement au châssis d'un matériel ferroviaire, tel un bogie ou une structure inférieure d'un wagon. Classiquement, la boite d'essieu 1 présente, de part et d'autre de son axe, une table d'appui 2 encore appelée palette portant un dispositif de maintien 3 pour la base 4 d'un ensemble élastique 5 d'une suspension, lequel ensemble élastique 5 comprend lui même un premier 5a ressort dit ressort de tare et un second 5b ressort dit ressort de charge monté à l'intérieur du ressort de tare.Referring to the drawing, it can be seen that the suspension of the railway vehicle comprises an axle, the ends of which are guided in rotation in an axle box 1 associated at least indirectly with the chassis of railway equipment, such as a bogie or a lower structure d 'a wagon. Conventionally, the axle box 1 has, on either side of its axis, a support table 2 also called a pallet carrying a holding device 3 for the base 4 of an elastic assembly 5 of a suspension, which elastic assembly 5 itself comprises a first spring 5a said tare spring and a second spring 5b said load spring mounted inside the tare spring.
Cette table d'appui 2 est solidaire de la boite d'essieu 1.This support table 2 is integral with the axle box 1.
Au lieu que l'ensemble élastique repose par sa base en totalité sur un même plan de la table d'appui qui est celui de la face supérieure de la table d'appui, selon l'invention, la table d'appui 2 présente une cavité 6 qui, sans diminuer notablement la résistance mécanique de ladite table, est apte à recevoir et loger sur une hauteur prédéterminée au moins le ressort 5b de charge.Instead of the elastic assembly resting at its base entirely on the same plane of the support table which is that of the upper face of the support table, according to the invention, the support table 2 has a cavity 6 which, without significantly reducing the mechanical resistance of said table, is capable of receiving and accommodating at a predetermined height at least the load spring 5b.
Ceci permet, pour une distance constructionnelle entre la face supérieure de la table et le point d'appui de l'extrémité haute de l'ensemble élastique, d'augmenter la longueur totale du ressort par rapport à un montage dit traditionnel où la base du ressort de charge repose sur la face supérieure de la table.This allows, for a structural distance between the upper face of the table and the fulcrum of the upper end of the elastic assembly, to increase the total length of the spring compared to a so-called traditional assembly where the base of the load spring rests on the upper side of the table.
De préférence, cette cavité 6 a une forme tronconique de révolution.Preferably, this cavity 6 has a frustoconical shape of revolution.
Dans une forme préférée de réalisation, au lieu que la base du ressort de charge repose librement directement dans une cavité 6 solidaire de la table d'appui, cette cavité 6 est réalisée par un pot amovible 6a dit de centrage qui porte en sa partie supérieure une collerette 7 d'appui qui coopère avec la face 8 supérieure de la table d'appui et c'est dans le pot que se loge partiellement le ressort de charge.In a preferred embodiment, instead of the base of the load spring freely resting directly in a cavity 6 integral with the support table, this cavity 6 is produced by a removable pot 6a, said to be centering, which carries in its upper part a support flange 7 which cooperates with the upper face 8 of the support table and it is in the pot that the load spring is partially housed.
C'est au moins indirectement la face interne 9 de cette cavité 6 ou du pot 6a de centrage qui fait office de portée de centrage du ressort de charge.It is at least indirectly the internal face 9 of this cavity 6 or of the centering pot 6a which acts as a centering surface for the load spring.
Le fond du pot reçoit la base du ressort de tare. Selon l'invention, la face supérieure 14 de la collerette 7 reçoit la base du ressort 5a de tare. Le bord externe 10 de la collerette d'appui du pot de centrage porte une chemise 11 dont la face interne 12 constitue pour le ressort 5a de tare une portée de centrage.The bottom of the pot receives the base of the tare spring. According to the invention, the upper face 14 of the collar 7 receives the base of the tare spring 5a. The outer edge 10 of the support flange of the centering pot carries a jacket 11 whose internal face 12 constitutes for the tare spring 5a a centering surface.
Avantageusement, la chemise 11 présente au moins une découpe 15 qui évite, lors de la phase de compression de l'élément élastique, que l'anneau 16 de suspension que comprend généralement ce type de suspension vienne en butée sur le bord supérieur de la chemise, ce qui limiterait l'amplitude d'évolution de l'élément élastique. Avantageusement, le pot 6a de centrage comprend des moyens 13 de liaison démontable avec l'ensemble élastique tels une tige qui s'appuie sur le dessous du pot de centrage et au moins indirectement sur la partie supérieure de l'ensemble élastique.Advantageously, the jacket 11 has at least one cutout 15 which prevents, during the compression phase of the elastic element, that the suspension ring 16 that this type of suspension generally comprises comes into abutment on the upper edge of the shirt , which would limit the amplitude of evolution of the elastic element. Advantageously, the centering pot 6a comprises means 13 for removable connection with the elastic assembly such as a rod which rests on the underside of the pot. centering and at least indirectly on the upper part of the elastic assembly.
De préférence, le fond du pot de centrage présente un bossage 17 délimitant une cavité suffisante pour y loger le pied du moyen 13 de liaison et de ce fait, limiter la longueur de la tige et l'encombrement total de l'ensemble élastique.Preferably, the bottom of the centering pot has a boss 17 delimiting a cavity sufficient to accommodate the foot of the connecting means 13 and therefore limit the length of the rod and the total size of the elastic assembly.
En outre, ce bossage constitue un élément de centrage pour le ressort de charge. Avantageusement, la disposition des portées de centrage 9 et 12 du ressort de charge et du ressort de tare permet de diminuer la différence de diamètre entre le ressort de charge et le ressort de tare. In addition, this boss constitutes a centering element for the load spring. Advantageously, the arrangement of the centering surfaces 9 and 12 of the load spring and the tare spring makes it possible to reduce the difference in diameter between the load spring and the tare spring.
