Description

La présente invention concerne une structure de wagon à ouverture latérale totale.The present invention relates to a wagon structure with full lateral opening.

De tels wagons sont connus et comportent généralement un châssis, deux bouts et un tôit, parfois avec en plus une cloison transversale intermédiaire. Ces divers éléments de l'ossature porteuse sont reliés rigidement entre eux de façon à délimiter des ouvertures latérales totales pour l'accès du chargement, ces ouvertures pouvant être fermées pendant le transport par des portes coulissantes ou des bâches.Such wagons are known and generally include a chassis, two ends and a roof, sometimes with an additional transverse bulkhead. These various elements of the supporting frame are rigidly connected together so as to delimit total lateral openings for access to the load, these openings being able to be closed during transport by sliding doors or tarpaulins.

Le problème de résistance le plus important dans le wagonnage est posé par le tamponnement. Pour résoudre ce problème en ce qui concerne la structure, les wagons comportent des bouts renforcés fortement encastrés dans le châssis du wagon.The most important resistance problem in waggons is posed by buffering. To solve this problem with regard to the structure, the wagons have reinforced ends strongly embedded in the frame of the wagon.

Or, sous l'effet de la charge utile le châssis se déforme et prend une flèche. Si le toit ne reliait pas les bouts de wagon , ces derniers auraient tendance à se rapprocher à leurs parties hautes. Sous l'effet de la charge le toit travaille donc en compression et les bouts en flexion,introduisant ainsi un moment dans les extrémités du châssis.However, under the effect of the payload the chassis deforms and takes an arrow. If the roof did not connect the ends of the wagon, the latter would tend to approach their upper parts. Under the effect of the load the roof therefore works in compression and the ends in bending, thus introducing a moment into the ends of the chassis.

L'expérience montre que cette contrainte permanente en charge provoque des fissurations par vieillissement du métal. Par ailleurs, les efforts ainsi engendrés dans le toit obligent à augmenter son poids.Experience shows that this permanent load stress causes cracking by aging of the metal. In addition, the efforts thus generated in the roof make it necessary to increase its weight.

La présente invention vise à annihiler l'introduction par la charge utile de contraintes dans les bouts et dans le toit, ce qui a pour conséquence d'alléger ces éléments et d'éviter leur renforcement, ainsi que dans certains cas celui du châssis.The present invention aims to annihilate the introduction by the payload of constraints in the ends and in the roof, which has the consequence of lightening these elements and of avoiding their reinforcement, as well as in certain cases that of the chassis.

Dans ce but et conformément à l'invention, l'un au moins des noeuds de liaison des éléments précités de l'ossature porteuse présente un degré de liberté en pivotement.For this purpose and in accordance with the invention, at least one of the connecting nodes of the aforementioned elements of the supporting frame has a degree of freedom in pivoting.

Suivant une première forme de réalisation particulièrement avantageuse, le noeud de liaison entre l'un des bouts et le châssis est un encastrement, les autres noeuds étant des articulations au moins partielles.According to a first particularly advantageous embodiment, the connection node between one of the ends and the chassis is an embedding, the other nodes being at least partial articulations.

Suivant une deuxième forme de réalisation également intéressante, le noeud de liaison de la cloison intermédiaire avec le châssis est un encastrement, les cinq autres noeuds de liaison étant des articulations au moins partielles.According to a second equally advantageous embodiment, the node connecting the intermediate partition with the chassis is an embedding, the other five connecting nodes being at least partial joints.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, sur le dessin annexé.Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.

Sur ce dessin, les figures 1 à 5 sont des élévations schématiques analogues illustrant cinq formes de réalisation différentes d'un wagon perfectionné, conforme à l'invention.In this drawing, Figures 1 to 5 are similar schematic elevations illustrating five different embodiments of an improved wagon, according to the invention.

Le wagon comporte un châssis 1 supporté, par l'intermédiaire de suspensions appropriées,par des éléments roulants 2 tels que des bogies et équipé de dispositifs de tamponnement 3. Ce châssis est relié par des bouts 4, 5 et, éventuellement, une cloison transversale intermédiaire 6, à un toit 7 afin de former une ossature porteuse couverte mais ouverte latéralement.The wagon comprises a chassis 1 supported, by means of appropriate suspensions, by rolling elements 2 such as bogies and equipped with buffering devices 3. This chassis is connected by ends 4, 5 and, optionally, a transverse partition. intermediate 6, to a roof 7 in order to form a load-bearing framework covered but open laterally.

Suivant la première forme de réalisation (figure 1), le bout 4 et le châssis 1 sont encastrés l'un dans l'autre en 8 et forment un ensemble rigide. Par contre, il n'y a pas d'encastrements entre les bouts 4, 5 et le toît 7, ni entre le bout 5 et le châssis 1 ; ces divers éléments sont reliés entre eux au moyen d'articulations au moins partielles 9 à 11 qui permettent une très légère rotation relative autour de leurs axes fictifs sans introduire de contrainte sensible dans les tôles de liaison.According to the first embodiment (Figure 1), the end 4 and the frame 1 are embedded one inside the other at 8 and form a rigid assembly. On the other hand, there is no embedding between the ends 4, 5 and the roof 7, nor between the end 5 and the frame 1; these various elements are interconnected by means of at least partial articulations 9 to 11 which allow a very slight relative rotation around their fictitious axes without introducing appreciable stress into the connecting plates.

Si au tamponnement, une force F1 est appliquée sur le bout 4, elle se trouve transmise aux tampons 3 et elle engendre un moment dans l'encastrement 8 de ce bout 4 relativement au châssis 1. Par contre, le chargement déforme légèrement ce châssis, mais n'introduit aucune contrainte dans l'ossature qui se déforme par des rotations de très faible amplitude des articulations 9 à 11. Si le tamponnement se produit dans le sens opposé, une force F2est appliquée sur le bout 5 et se répartit entre le châssis 1 et le toit 7 qui est retenu par le bout 4 ; il en résulte un moment de sens inverse au précédent dans l'encastrement 8.If at buffering, a force F1 is applied to the end 4, it is transmitted to the buffers 3 and it generates a moment in the embedding 8 of this end 4 relative to the chassis 1. On the other hand, the loading slightly deforms this chassis, but does not introduce any constraint into the framework which deforms by very small amplitude rotations of the joints 9 to 11. If the buffering occurs in the opposite direction, a force F2 is applied to the end 5 and is distributed between the chassis 1 and the roof 7 which is retained by the end 4; this results in a moment of opposite direction to the previous one in the embedding 8.

Suivant la deuxième forme de réalisation (figure 2), le bout 4 et le toit 7 sont encastrés l'un .dans l'autre en 12 et forment un ensemble rigide. Par contre, les bouts 4, 5 sont reliés avec le châssis 1 et le bout 5 avec le toit 7 par des articulations au moins partielles 13 et 11, 10 respectivement. Cette réalisation est comparable à la précédente en ce qui concerne la diffusion des efforts, mais dans ce cas un moment important doit être supporté par le toit 7. Celui-ci est alors alourdi mais le châssis 1 peut être allégé.According to the second embodiment (Figure 2), the end 4 and the roof 7 are embedded one in the other at 12 and form a rigid assembly. On the other hand, the ends 4, 5 are connected with the chassis 1 and the end 5 with the roof 7 by at least partial articulations 13 and 11, 10 respectively. This achievement is comparable to the previous one with regard to the diffusion of the forces, but in this case a significant moment must be supported by the roof 7. The latter is then weighed down but the chassis 1 can be lightened.

Suivant la troisième forme de réalisation (figure 3), les deux bouts 4 et 5 sont encastrés dans le toit 7 en 12 et 14 respectivement ; ils sont reliés au châssis 1 par des articulations au moins partielles 13 et 11 respectivement. L'application de la force F 1 ou F2 engendre deux moments extrêmes sur le toit, moments qui sont moitié du précédent selon la figure 2. Par ailleurs, la déformation du châssis 1 sous l'effet de la charge utile n'entraîne aucune variation de longueur, donc aucune contrainte dans le portique rigide constitué par les bouts 4, 5 et le toit 7.According to the third embodiment (Figure 3), the two ends 4 and 5 are embedded in the roof 7 at 12 and 14 respectively; they are connected to the chassis 1 by at least partial articulations 13 and 11 respectively. The application of the force F 1 or F2 generates two extreme moments on the roof, moments which are half of the previous one according to FIG. 2. Furthermore, the deformation of the chassis 1 under the effect of the payload does not cause any variation. in length, so no constraints in the rigid gantry formed by the ends 4, 5 and the roof 7.

Suivant la quatrième forme de réalisation (figure 4), la cloison transversale intermédiaire 6 est encastrée dans le châssis 1 en 15 et reliéeau toit 7 par une articulation au moins partielle 16, d'autres articulations du même type 9, 10 et 13, 11 reliant le toit 7 et le châssis 1 aux bouts 4 et 5 respectivement. Dès lors, la force Fl précitée se décompose en deux forces F 14 et F 16 appliquées respectivement sur le bout 4 et la cloison 6 ; de même, la force F2 se décompose en deux forces F 25 et F26 appliqués respectivement sur le bout 5 et la cloison 6 ; les éléments 4, 5 et 6 sont donc soumis à des sollicitations moitié. D'autre part, la liaison particulière de la cloison 6 avec le toit 7 conduit à ce que ce toit 7 prend la même flèche que le châssis 1 sous l'effet de la charge utile et participe donc à la résistance.According to the fourth embodiment (Figure 4), the intermediate transverse partition 6 is embedded in the chassis 1 at 15 and connected to the roof 7 by an at least partial articulation 16, other articulations of the same type 9, 10 and 13, 11 connecting the roof 7 and the chassis 1 at the ends 4 and 5 respectively. Consequently, the aforementioned force F1 breaks down into two forces F 14 and F 16 applied respectively to the end 4 and the partition 6; similarly, the force F2 breaks down into two forces F 25 and F26 applied respectively to the end 5 and the partition 6; elements 4, 5 and 6 are therefore subjected to half stresses. On the other hand, the particular connection of the partition 6 with the roof 7 leads to the fact that this roof 7 takes the same deflection as the chassis 1 under the effect of the payload and therefore participates in the resistance.

Suivant la cinquième forme de réalisation (figure 5), la cloison transversale intermédiaire 6 est encastrée dans le toit 7 en 17 et articulée relativement au châssis 1 en 18, tous les autres éléments étant reliés entre eux par des articulations au moins partielles 9, 10, 11 et 13.According to the fifth embodiment (Figure 5), the intermediate transverse partition 6 is embedded in the roof 7 at 17 and articulated relative to the frame 1 at 18, all the other elements being connected together by at least partial articulations 9, 10 , 11 and 13.

L'invention n'est pas limitée aux formes de réalisation représentées et décrites en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiments shown and described in detail, since various modifications can be made thereto without departing from its scope.
