Definitions
- the present invention relates to a chassis for a rail vehicle bogie.
- 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.
- a bogie frame comprises two parallel beams connected by two crosspieces perpendicular to the beams.
- 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.
- 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.
- the invention therefore consists in adding at least one auxiliary beam, which also ensures better overall rigidity of the chassis.
- 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 beam connecting the two crosspieces.
- the chassis comprises two auxiliary beams each arranged in the vicinity of one of the main beams and parallel to them.
- the chassis comprises two main longitudinal beams 10 and 20 connected by crosspieces 30 and 40.
- 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.
- the auxiliary beams give greater rigidity to the chassis and in particular to the cross members.
- the auxiliary beams can be made in the form of mechanically welded or molded tubes. They are welded to the crosspieces 30, 40.
- the side members 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.
- 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.
- 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.
- connection between two adjacent crowns is carried out by bolting and, of course, in order to improve the position crowns 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.
- 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.
- 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, 66A are connected by bolting.
Abstract
Description
- La présente invention est relative à un châssis pour bogie de véhicule ferroviaire.
- 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.
- Classiquement, un châssis de bogie comprend deux longerons parallèles reliés par deux traverses perpendiculaires aux longerons.
- Les efforts subis par le châssis sont importants à la jonction longeron-traverse.
- 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.
- 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.
- L'invention consiste donc à rajouter au moins un longeron auxiliaire, ce qui assure en outre une meilleure rigidité d'ensemble du châssis.
- 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.
- De préférence, le châssis comprend deux longerons auxiliaires disposés chacun au voisinage d'un des longerons principaux et parallèlement à ceux-ci.
- 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.
- La figure 1 représente une vue en perspective du premier mode de réalisation dans lequel les longerons auxiliaires sont soudés sur les traverses.
- 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.
- La figure 3 représente, en vue partielle, une variante du deuxième mode de réalisation.
- Dans la figure 1 le châssis comprend deux longerons longitudinaux principaux 10 et 20 reliés par des traverses 30 et 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.
- Les longerons auxiliaires confèrent une plus grande rigidité au châssis et notamment aux traverses.
- Les longerons auxiliaires peuvent être réalisés sous forme de tubes mécano-soudés ou moulés. Ils sont soudés sur les traverses 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.
- 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.
- 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.
- 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.
- La liaison mécanique entre deux couronnes adjacentes est réalisée par boulonnage et, bien entendu, afin d'améliorer le position nement 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.
- 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.
- 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, 66A sont reliées par boulonnage.
