Abstract
Description
L'invention se rapporte à un wagon pour charge lourde.The invention relates to a wagon for heavy load.
Elle se rapporte plus particulièrement mais non exclusivement à un wagon citerne.It relates more particularly but not exclusively to a wagon tank.
Classiquement, un wagon se compose d'organes de roulement tels les roues d'un ou plusieurs bogies destinés à soutenir une charge.Conventionally, a wagon consists of running gear such as wheels one or more bogies for supporting a load.
Les bogies supportent, via une articulation pivot, un châssis lequel porte une charge telle une citerne ou une caisse etc.The bogies support, via a pivot joint, a frame which carries a load such as a tank or a crate etc.
Lorsque l'on souhaite augmenter la charge, se pose comme problème les effets de celle-ci sur les rails.When it is desired to increase the load, the problem arises effects of it on the rails.
En effet, les forces verticales et horizontales tendent à dégrader significativement les rails et plus la charge est lourde plus ces forces sont importantes.Indeed, the vertical and horizontal forces tend to degrade significantly the rails and the heavier the load is the more these forces are important.
Pour atténuer ces effets, on a déjà construit des wagons à huit essieux et donc des wagons soutenus à chaque extrémité par deux bogies comportant chacun deux essieux. To mitigate these effects, eight-axle wagons have already been built and wagons supported at each end by two bogies each carrying two axles.
Chaque paire de bogies extrêmes soutient par une articulation à pivot plat un châssis intermédiaire s'étendant entre les deux bogies portant quant à lui un châssis principal.Each pair of extreme bogies supports with a flat swivel joint a intermediate chassis extending between the two bogies carrying a chassis main.
Les tampons et le point de traction se situent dans l'axe du châssis porté par les bogies et les points de pivots avec le châssis sont décalés verticalement de sorte que les efforts longitudinaux modifient notamment les forces verticales ce qui, en outre, dégrade le comportement du wagon.The buffers and the point of traction are located in the axis of the chassis carried by the bogies and the pivot points with the chassis are vertically offset so that the longitudinal forces modify, in particular, the vertical forces which, in in addition, degrades the behavior of the wagon.
Un wagon du type ci-dessus est décrit dans le document US-A-3 645 213.A wagon of the above type is described in US-A-3,645,213.
L'invention a pour objectif un wagon qui remédie notamment aux problèmes évoqués ci dessus.The invention aims at a wagon which remedies the problems mentioned above.
A cet effet l'invention a pour objet un wagon comprenant :
- deux groupes de quatre essieux organisés en bogie supportant une structure accueillant une charge,
- pour chaque groupe de bogie, d'une part des moyens d'application d'une force longitudinale dite de déplacement et d'autre part des pivots de liaison avec au moins indirectement la charge ce wagon étant caractérisé en ce que chaque groupe de deux bogies est, par les pivots de liaison, associé à un cadre portant les moyens d'application de la force longitudinale dite de déplacement avec, d'une part, portée par la face supérieure du cadre, une liaison à pivot avec la structure contenant la charge laquelle liaison à pivot est alignée avec les moyens d'application précités et d'autre part c'est directement l'enveloppe contenant la charge qui transmet les efforts longitudinaux entre les deux groupes de bogie.
- two groups of four axles organized in bogie supporting a structure accommodating a load,
- for each bogie group, on the one hand means for applying a longitudinal displacement force and on the other hand connecting pivots with at least indirectly the load, this wagon being characterized in that each group of two bogies is, by the connecting pins, associated with a frame carrying the means for applying the longitudinal displacement force with, on the one hand, carried by the upper face of the frame, a pivot connection with the structure containing the load which pivot connection is aligned with the aforementioned application means and secondly it is directly the casing containing the load which transmits the longitudinal forces between the two bogie groups.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple au regard du dessin qui représente schématiquement :

- wagon citerne

- vertical axial section of the tank car.
En se reportant au dessin on voit un wagon 1.Referring to the drawing we see a car 1.
Ce wagon porte une charge contenue dans une enveloppe 2.This car carries a load contained in an
Dans l'exemple représenté mais sans limitation, il s'agit d'un wagon citerne mais il pourrait s'agir d'un autre type de produit transporté et par exemple faisant appel à une caisse ou une plate-forme. In the example shown but without limitation, it is a tank car but it could be another type of product transported and for example call to a cash register or a platform.
De manière classique ce wagon comprend :
- deux groupes A, B, de quatre
essieux 3 organisés enbogie 4 supportant une structure accueillant une charge, - pour chaque groupe de bogie, d'une part des
moyens 5,6 d'application d'une force longitudinale dite de traction ou de compression et, d'autre part, des pivots 7 de liaison au moins indirectement liés avec la charge.
- two groups A, B, of four
axles 3 organized inbogie 4 supporting a structure accommodating a load, - for each group of bogie, on the one hand means 5,6 applying a longitudinal force called traction or compression and, on the other hand, connecting pins 7 at least indirectly related to the load.
Par moyens d'application d'une force longitudinale de traction ou de compression, on comprendra tant la liaison (crochet/anneau) avec par exemple la locomotive de traction que les tampons utilisés lors du freinage.By means of application of a longitudinal force of traction or compression, we will understand both the connection (hook / ring) with for example the traction locomotive as the buffers used during braking.
Pour certains types de liaison, la liaison crochet/anneau fait également office de tampon.For certain types of connection, the hook / ring connection also serves buffer.
Chaque bogie comprend une poutre 8 transversale, deux poutres 9
longitudinales, une liaison 7 supérieure à pivot et deux essieux 3.Each bogie comprises a
Bien évidemment, sont également prévus des suspensions, des organes de freinage et une timonerie de commande du freinage.Of course, there are also suspensions, braking and a braking control linkage.
Selon l'invention, chaque groupe A, B, de deux bogies est, par les pivots 7 de
liaison, associé à un cadre 10 portant les moyens d'application de la force
longitudinale dite de déplacement avec d'une part, portée par la face supérieure du
cadre, une liaison 11 à pivot avec la structure contenant la charge laquelle liaison 11
à pivot est alignée avec les moyens 5,6 d'application précités et d'autre part c'est
directement l'enveloppe 2 contenant la charge qui transmet les efforts longitudinaux
entre les deux groupes A, B de bogie.According to the invention, each group A, B, of two bogies is, by the pivots 7 of
link, associated with a
La structure 2 est donc portée par deux cadres 10 indépendants.The
Cette liaison 11 à pivot avec la structure se compose d'un pivot comportant
une partie de sphère en son sommet qui coopère avec une cavité partiellement
sphérique que présente la base de la structure 2.This
Avantageusement, au droit de cette liaison à pivot, la structure présente des moyens 12 de renforcement de celle ci.Advantageously, at the right of this pivot link, the structure has means 12 of reinforcing it.
Dans le cas par exemple d'une citerne, ce renforcement 12 est réalisé par une
frette 12 interne à la citerne dont le rôle n'est plus uniquement dédié à la résistance
au flambage mais à la transmission des efforts. In the case for example of a tank, this
Par rapport aux autres frettes que comportent habituellement cette citerne , la hauteur et l'épaisseur de la frette sont majorées.Compared to the other frets that usually comprise this tank, the height and thickness of the hoop are increased.
A titre de comparaison, la hauteur habituelle de la frette est de 100 mm environ alors que pour cette citerne la hauteur est comprise entre 300 et 400 mm environ.For comparison, the usual height of the hoop is 100 mm approximately while for this tank the height is between 300 and 400 mm about.
L'épaisseur habituelle est de 6 mm environ alors que dans le cas présent elle est de 15 à 20 mm environ.The usual thickness is about 6 mm whereas in the present case it is is about 15 to 20 mm.
L'acier utilisé est à haute limite élastique genre S 550 MC ou P 460MLThe steel used is high elastic limit type S 550 MC or P 460ML
On note que la hauteur de la frette varie en décroissant depuis le bas vers le haut.Note that the height of the hoop varies in decreasing from the bottom to the high.
Lorsque la forme de la structure n'est pas un cylindre, les moyens de renforcement utilisés sont adaptés à cette forme.When the shape of the structure is not a cylinder, the means of reinforcement used are adapted to this form.
Comme on peut le voir chaque cadre 10 soutenu par le groupe de bogie se
compose de trois poutrelles 13 longitudinales dont une centrée sur l'axe longitudinal.As can be seen each
La poutrelle médiane porte sur sa face supérieure la partie mâle du pivot.The median beam carries on its upper face the male part of the pivot.
Inversement, il pourrait s'agir de la partie femelle.Conversely, it could be the female part.
Ce cadre, pour être relié à une locomotive ou à un autre wagon, se prolonge
au delà de l'extrémité de la structure, d'un côté par des bras 14 qui s'élèvent pour
que les points d'application des forces soient dans le plan horizontal contenant le pivot 11.This frame, to be connected to a locomotive or another wagon, extends
beyond the end of the structure, on one side by
On notera que pour alléger ce cadre les poutrelles ou poutres des bogies sont évidées.It will be noted that to lighten this frame the beams or beams of the bogies are cored.
Une autre caractéristique intéressante est le positionnement des points de pivotement sur la structure.Another interesting feature is the positioning of the points of pivoting on the structure.
Ces points de pivotement sont écartés d'une distance de l'ordre de 60% de la longueur de la charge, les 40% restant étant répartis de part et d'autre.These pivot points are separated by a distance of about 60% of the length of the load, the remaining 40% being distributed on both sides.
La situation antérieure était de 80% à 90% entre les points de pivots. Il y a donc une transmission plus régulière des charges le long du wagon.The previous situation was 80% to 90% between the pivot points. There is therefore a more regular transmission of loads along the wagon.
Cette disposition permet de désynchroniser les efforts verticaux et horizontaux des roues aux rails.This arrangement makes it possible to desynchronize the vertical and horizontal forces wheels to the rails.
Le wagon se comporte comme un filtre passe bas.The car behaves like a low pass filter.
Du fait que les extrémités des cadres reposant sur les bogies sont relevées, la citerne se termine en ses extrémités par une forme tronconique. Since the ends of the frames resting on the bogies are raised, the tank ends in its ends by a frustoconical shape.
On a donc une architecture à six pivots et douze lisoirs qui contribuent à ce filtrage.So we have an architecture with six pivots and twelve sliders that contribute to this filtering.
Avantageusement, la suspension est du type viscoélastique.Advantageously, the suspension is of the viscoelastic type.
Le porte-à-faux par rapport à la liaison 11 à pivot est de petite longueur, ce
qui permet la compatibilité au montage de l'attelage automatique de choc et traction,
tout en autorisant une longueur de plate-forme utile supérieure à 22 m.The cantilever relative to the
