Description

La présente invention est relative à un châssis pour bogie de véhicule ferroviaire.The present invention relates to a chassis for a rail vehicle bogie.

Le châssis de bogie est la structure qui reçoit toutes les fonctions du bogie (support de caisse, support des roues, dispositifs de freinage, etc...) ; il sert à transmettre tous les efforts entre la caisse et les roues.The bogie chassis is the structure that receives all of the bogie's functions (body support, wheel support, braking devices, etc.); it is used to transmit all the forces between the body and the wheels.

Classiquement, un châssis de bogie comprend deux longerons parallèles reliés par deux traverses perpendiculaires aux longerons.Conventionally, a bogie frame comprises two parallel beams connected by two crosspieces perpendicular to the beams.

Les efforts subis par le châssis sont importants à la jonction longeron-traverse.The forces undergone by the chassis are significant at the spar-cross junction.

L'augmentation des vitesses d'exploitation des chemins de fer a pour conséquence d'augmenter les contraintes sur le châssis et, en particulier, les forces longitudinales exercées sur les longerons, notamment lors du freinage du véhicule.The increase in railway operating speeds has the consequence of increasing the stresses on the chassis and, in particular, the longitudinal forces exerted on the side members, in particular when the vehicle is braking.

Le but de l'invention est de réaliser un châssis dans lequel l'encastrement de la traverse sur le longeron est soumis à des efforts moins importants lors des accélérations et décélérations.The object of the invention is to produce a chassis in which the embedding of the cross member on the spar is subjected to less significant forces during accelerations and decelerations.

L'invention consiste donc à rajouter au moins un longeron auxiliaire, ce qui assure en outre une meilleure rigidité d'ensemble du châssis.The invention therefore consists in adding at least one auxiliary beam, which also provides better overall rigidity of the chassis.

L'invention a pour objet un châssis pour bogie de véhicule ferroviaire, comprenant deux longerons principaux reliés par deux traverses, caractérisé en ce qu'il comprend au moins un longeron auxiliaire reliant les deux traverses et solidement fixé à ces traverses, contrairement au bogie selon FR-A-1 452 450 où le longeron auxiliaire est monté sur les travers de manière à consentir une rotation par rapport à elles.The invention relates to a chassis for a bogie of a railway vehicle, comprising two main beams connected by two crosspieces, characterized in that it comprises at least one auxiliary spar connecting the two crossbeams and securely fixed to these crossbeams, unlike the bogie according to FR-A-1 452 450 where the auxiliary spar is mounted on the cross members so as to allow rotation relative to them.

De préférence, le châssis comprend deux longerons auxiliaires disposés chacun au voisinage d'un des longerons principaux et parallèlement à ceux-ci.Preferably, the chassis comprises two auxiliary beams each arranged in the vicinity of one of the main beams and parallel to them.

Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, deux modes de réalisation du châssis de bogie selon l'invention.There are described below, by way of example and with reference to the accompanying drawings, two embodiments of the bogie frame according to the invention.

  • La figure 1 représente une vue en perspective du premier mode de réalisation dans lequel les longerons auxiliaires sont soudés sur les traverses.Figure 1 shows a perspective view of the first embodiment in which the auxiliary beams are welded to the sleepers.
  • La figure 2 représente une vue en perspective, partiellement éclatée, du deuxième mode de réalisation dans lequel chaque longeron auxiliaire est boulonné sur les traverses et sur un longeron principal.Figure 2 shows a perspective view, partially exploded, of the second embodiment in which each auxiliary spar is bolted to the cross members and to a main spar.
  • La figure 3 représente, en vue partielle, une variante du deuxième mode de réalisation.FIG. 3 represents, in partial view, a variant of the second embodiment.

Dans la figure 1 le châssis comprend deux longerons longitudinaux principaux 10 et 20 reliés par des traverses 30 et 40.In FIG. 1, the chassis comprises two main longitudinal beams 10 and 20 connected by crosspieces 30 and 40.

Conformément à l'invention, le châssis comprend en outre deux longerons auxilaires 50 et 60, parallèles aux longerons auxiliaires et reliant les deux traverses. Ils sont avantageusement disposés chacun à proximité d'un des longerons, ce qui leur permet de soulager les encastrements des traverses dans les longerons principaux.According to the invention, the chassis further comprises two auxiliary beams 50 and 60, parallel to the auxiliary beams and connecting the two crosspieces. They are advantageously arranged each near one of the beams, which allows them to relieve the embedding of the sleepers in the main beams.

Les longerons auxiliaires confèrent une plus grande rigidité au châssis et notamment aux traverses.The auxiliary beams give greater rigidity to the chassis and in particular to the cross members.

Les longerons auxiliaires peuvent être réalisés sous forme de tubes mécano-soudés ou moulés. Ils sont soudés sur les traverses 30, 40.The auxiliary beams can be made in the form of mechanically welded or molded tubes. They are welded to the crosspieces 30, 40.

On peut envisager de placer un seul longeron auxiliaire ou plus de deux et les fixer aux traverses selon un angle différent d'un angle droit.It is possible to envisage placing a single auxiliary beam or more than two and fixing them to the crosspieces at an angle different from a right angle.

Dans la figure 2, les longerons 10, 20 se composent chacun d'une poutre 11,21 et de deux couronnes de liaison 12, 13; 22, 23, dans cette figure, seules les couronnes 22, 23 du longeron 20 étant clairement représentées.In Figure 2, the beams 10, 20 each consist of a beam 11,21 and two connecting rings 12, 13; 22, 23, in this figure, only the rings 22, 23 of the spar 20 being clearly represented.

Les traverses 30, 40 se composent chacune d'un tube 31,41 portant deux couronnes de liaison 32, 33; 42, 43, et deux potences soutenant une barre-support de freins 36, seules les deux potences 34, 35 et la barre-support 36 de la traverse 30 étant représentées.The crosspieces 30, 40 each consist of a tube 31, 41 carrying two connecting rings 32, 33; 42, 43, and two brackets supporting a brake support bar 36, only the two brackets 34, 35 and the support bar 36 of the cross member 30 being shown.

Les longerons auxiliaires 50, 60 se composent chacun d'une poutre 51,61 et de quatre couronnes de liaison, seules les couronnes de liaison 62, 63, 64, 65 du longeron auxiliaire 60 étant clairement représentées.The auxiliary beams 50, 60 each consist of a beam 51,61 and four connecting rings, only the connecting rings 62, 63, 64, 65 of the auxiliary beam 60 being clearly represented.

La liaison mécanique entre deux couronnes adjacentes est réalisée par boulonnage et, bien entendu, afin d'améliorer le positionnement des couronnes entre elles, la liaison peut comporter un emboîtement circulaire. La liaison peut aussi être réalisée par des boulons traversant chacun les quatre couronnes, par exemple, les couronnes 22, 64, 62, 33.The mechanical connection between two adjacent rings is carried out by bolting and, of course, in order to improve the positioning of the rings between them, the connection may include a circular interlocking. The connection can also be achieved by bolts each passing through the four crowns, for example, the crowns 22, 64, 62, 33.

La figure 3 montre une variante de réalisation dans laquelle la barre-support de freins est directement reliée à l'extrémité d'un longeron auxiliaire, de sorte que les potences sont supprimées.Figure 3 shows an alternative embodiment in which the brake support bar is directly connected to the end of an auxiliary beam, so that the brackets are eliminated.

La poutre 61 du longeron secondaire 60 est prolongée, au-delà des couronnes de liaison, par une protubérance 66 terminée par une plaque de liaison 66A. La barre 36 comporte une plaque de liaison 36A, et les deux plaques 36A, 66Asont reliées par boulonnage.The beam 61 of the secondary spar 60 is extended, beyond the connecting rings, by a protuberance 66 terminated by a connecting plate 66A. The bar 36 has a connecting plate 36A, and the two plates 36A, 66As are connected by bolting.
