Description

~3290~

Châ~si~ pour bo~ie de véhicule ferroviaire.
La pré~ente invention est relatlve a un châsi3is pour bogie de véhicule ferroviaire.
Le châssis de bogie est la structure qui reçoit toutes les fonotions du bogie (support de caisse, support des roues, disposltlfs de freinage, etc...) ; il i~ert à tran3mettre tous les e~forts entre la cai3se et les roues.
Classiquement, un châssis de bogie comprend deux longeron~
parallèles reliés par deux traverses perpendiculaires aux longerons.
Les efforts subis par le châssis sont importants à la ~onction longeron-traverse.
L'augmentation des vitesses d'exploitation des chemins de fer a pour conséquence d'augmenter les contraintes sur le chassi~
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 ~oumis à des efforts moins importants lors de~ accélération~ et décélérations.
L'invantion consiste donc à ra~outer au moins un longeron auxiliaire, ce qui assure en outre une meilleure rigidité d'ensemble du châssis.
L'invention a pour ob~et un châssis pour bogie de véhicule ferroviaire, incluant deux longerons principaux reliés par deux traverses, caractérisé en ce qu'il inclut au moins un longeron auxiliaire reliant les deux traverses et sol~aement fixé à ces traNerses.
De préférence, le châssls comprend deux longerons auxiliaires disposés chacun au voisinage d'un des longerons pr~nclpaux et parallè-;~ lement à ceux-ol.
~ Il est déorlt oi-après, à titre d'exemple et en référenoe ;;~ 30 aux dessins annexés, deux modes de réali~ation du ohâssis de bogie ~ selon l'invention.
,^ La figure 1 représente une vua en perspeotive du premier mode de réalisation dans lequel les longerons auxiliaires sont sQudés sur les traverses.
`~ 35 ~' ~,~,.. ~

~,:

- ~ 1329055 La figure 2 représente une vue en per~peotive, partiellement éclatée, du deuxième mode de réalisation dan~ lequel chaque longeron auxiliaire e~t boulonné sur les traverses et sur un longeron principal.
La figurs 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.
Con~ormément à l'invention, le châssis comprend en outre deux longerons auxilaires 50 et 60, parallèles aux longerons auxi-lialres et reliant les deux traversss. Ils sont avantageusement di~posés chacun à proximité d'un des longsrons, ce qui leur permet de soulager les encastrements des traver~es dans les longerons principaux.
Les longeron~ auxiliaire~ confèrent une plus grande rigidité
au châssis et notamment aux traverses.
Les longerons auxiliaires peuvent être réalisés sous I`orme de tube~ mécano-soudes ou moulés. Ils sont soudé~ sur le~ ~raverses 30, 40.
On peut envi~ager de placer un seul longeron aux1liaire ou plus de deux et le~ fixer aux traverses selon un angle dif~érent d'un angle droit.
Dans la figure 2, les longerons 10, 20 se composent chacun d'une poutre 119 21 et de deux couronnes de liaison 12, 13; 22, 23, dans cztte figure, ~eules les couronnes 22, 23 du longeron 20 étant clairement représentées.
Les traverses 30, 40 ~e composent chacune d'un tube 31, 41 i~
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, pien sntendu, afin d'améliorer le position-132gOS5 .. ~ - 3 -nement des oouronnes entre elles, la liaison peut comporter un embo~tement oir¢ulaire. La liaison peut aussi être réalisée par des boulons traversant chacun les quatre couronneq, par exemple, les couronnes 22, 64, 62, 33.
La ~igure 3 montre une variante de réalisation dans laquelle la barre-support de freins est directement reliée à l'extrémite d'un longeron auxiliaire, de sorte que les potences sont supprimées.
La poutre 61 du longeron secondaire 60 est prolongée, au-delà des oouronnes 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 qont reliées par boulonnage.

Châ ~ si ~ pour bo ~ ie of railway vehicle.
The pre ~ ent invention is relatlve to a frame for bogie of railway vehicle.
The bogie chassis is the structure that receives all the bogie fundamentals (body support, wheel support, disposltlfs braking, etc ...); it i ~ ert to transmit all e ~ strong between the case and the wheels.
Conventionally, a bogie chassis comprises two spar ~
parallel connected by two crosspieces perpendicular to the side members.
The stresses undergone by the chassis are significant at the anointing cross member.
The increase in operating speeds of railways iron has the consequence of increasing the stresses on the chassi ~
and, in particular, the longitudinal forces exerted on the side rails, especially when braking the vehicle.
The object of the invention is to produce a chassis in which the mounting of the cross member on the beam is ~ oumis à
less effort during ~ acceleration ~ and decelerations.
The advantage therefore consists in ra ~ outer at least one spar auxiliary, which also provides better overall rigidity of the chassis.
The invention has for ob ~ and a chassis for vehicle bogie rail, including two main beams connected by two sleepers, characterized in that it includes at least one spar auxiliary connecting the two sleepers and ground ~ aement fixed to these traNerses.
Preferably, the châssls includes two auxiliary beams each arranged in the vicinity of one of the longitudinal members pr ~ nclpaux and parallé-; ~ Lement to these ol.
~ It is now or later, by way of example and in reference ;; ~ 30 in the accompanying drawings, two embodiments ~ ation of the bogie chassis ~ According to the invention.
, ^ Figure 1 shows a perspective view of the first embodiment in which the auxiliary beams are sQudées on the sleepers.
`~ 35 ~ ' ~, ~, .. ~

~ ,:

- ~ 1329055 Figure 2 shows a view in per ~ peotive, partially exploded view, of the second embodiment dan ~ which each spar auxiliary e ~ t bolted to the cross members and to a main spar.
FIGS 3 represents, in partial view, a variant of the second embodiment.
In Figure 1 the chassis includes two longitudinal beams main 10 and 20 connected by crosspieces 30 and 40.
Con ~ ormément to the invention, the chassis further comprises two auxiliary beams 50 and 60, parallel to the auxiliary beams lines and connecting the two crossings. They are advantageously di ~ placed each near one of the longrons, which allows them relieve the embedding of travers ~ es in the side members main.
The side rails ~ auxiliary ~ provide greater rigidity to the chassis and in particular to the crosspieces.
The auxiliary beams can be made in the form of tube ~ mechanic-soda or molded. They are welded ~ on the ~ ~ raverses 30, 40.
We can envi ~ ager to place a single spar aux1liaire or more than two and fix it to the crosspieces at a dif ~ erent angle at a right angle.
In Figure 2, the side members 10, 20 each consist of a beam 119 21 and two connecting rings 12, 13; 22, 23, in cztte figure, ~ eules the crowns 22, 23 of the spar 20 being clearly represented.
The sleepers 30, 40 ~ e each consist of a tube 31, 41 i ~
carrying two connecting rings 32, 33; 42, 43, and two gallows 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 crowns, only the crowns - ~
connecting 62, 63, 64, 65 of the auxiliary beam 60 being clearly represented.
The mechanical connection between two adjacent crowns is carried out by bolting and, pien sntendu, in order to improve the position-132gOS5 .. ~ - 3 -between the turrets, the connection can include a oir ¢ ulaire interlocking. The connection can also be carried out by bolts each passing through the four crowns, for example, crowns 22, 64, 62, 33.
The ~ igure 3 shows an alternative embodiment in which the brake support bar is directly connected to the end an auxiliary spar, so that the brackets are eliminated.
The beam 61 of the secondary spar 60 is extended, au-beyond the connecting rods, by a protrusion 66 terminated by a connection plate 66A. Bar 36 has a plate 36A, and the two plates 36A, 66A qont connected by bolting.
