Abstract
Description
L'invention concerne un wagon à plateforme surbaissée.The invention relates to a wagon with a lowered platform.
Comme les wagons à plateforme de hauteur normale (FR-A-2.140.937), les wagons à plateforme surbaissée comprenennent, outre la plateforme proprement dite, des boggies supportant la dite plateforme, laquelle est constituée de brancards et longrines reliés par des traverses au moins d'extrémités et présente des semelles inférieure et supérieure, celles-ci formant ou recevant un plancher.Like the wagons with normal height platform (FR-A-2.140.937), the wagons with low platform include, in addition to the platform itself, bogies supporting the said platform, which consists of stretchers and stringers connected by crosspieces to the fewer ends and has lower and upper soles, these forming or receiving a floor.
Aux traverses d'extrémité sont évidemment associés les organes classiques notamment de traction et de tamponnement.The end crosspieces are obviously associated with the conventional members, in particular the traction and buffering members.
L'avantage des plateformes surbaissées est évidemment de pouvoir admettre des charges de plus grande hauteur sans dépasser le gabarit imposé par les normes en vigueur mais aussi, compte tenu de l'inclinaison des parties supérieures gauche et droite de ce gabarit, d'admettre une plus grande distance entre boggies et donc en courbe un déport latéral plus important sans dans la dite courbe interférer avec l'une des susdites parties inclinées du gabarit.The advantage of lowered platforms is obviously to be able to admit loads of greater height without exceeding the template imposed by the standards in force but also, given the inclination of the upper left and right parts of this template, to admit a greater distance between bogies and therefore in curve a greater lateral offset without in said curve interfering with one of the above inclined portions of the template.
Dans les wagons à plateforme de hauteur normale, afin de reporter sur les longrines de la plateforme les efforts de tamponnement et de traction et de décharger des contraintes correspondantes les brancards, en tête du chassis est prévue, pour relier la traverse d'extrémité aux longrines, une structure en caisson communément dite "écharpe" formée de deux plaques horizontales de forme sensiblement trapézoïdale dont la grande base s'étend au moins jusqu'aux organes de tamponnement et dont la petite base appuie sur les extrémités des longrines centrales, ces deux plaques étant reliées entre elles par des nervures verticales qui, depuis les longrines centrales, rejoignent l'arrière des traverses dans les plans verticaux des organes de tamponnement.In wagons with platform of normal height, in order to transfer to the sills of the platform the buffering and traction efforts and to discharge the corresponding stresses the stretchers, at the head of the chassis is provided, to connect the end cross member to the sills , a structure in a box commonly known as a "scarf" formed by two horizontal plates of substantially trapezoidal shape, the large base of which extends at least to the buffering members and the small base of which bears on the ends of the central sills, these two plates being connected between them by vertical ribs which, from the central sills, join the rear of the sleepers in the vertical planes of the buffering members.
Quel que soit le type de plateforme, la tête de chassis doit, derrière la traverse, réserver au droit du dispositif d'attelage un logement pour les organes essentiels du dispositif d'attelage automatique que sont la butée et l'amortisseur, lequel logement doit être d'axe horizontal et s'étendre sur une longueur imposée par celle des organes concernés.Whatever the type of platform, the chassis head must, behind the crossmember, reserve to the right of the coupling device a housing for the essential organs of the automatic coupling device that are the stop and the shock absorber, which housing must have a horizontal axis and extend over a length imposed by that of the bodies concerned.
Parmi les wagons à plateforme surbaissée, l'invention vise ceux qui, de manière à coopérer avec ceux portés à hauteur normale par un autre wagon, ont au moins l'une de leurs extrémités qui porte les moyens d'attelage à hauteur normale par exemple à mille deux cents millimètres du rail et non sous le plan de charge de la plateforme surbaissée, lequel se situe par exemple à neuf cent trente huit millimètres du rail.Among the wagons with low platform, the invention is aimed at those which, in order to cooperate with those carried at normal height by another wagon, have at least one of their ends which carries the coupling means at normal height for example one thousand two hundred millimeters from the rail and not under the load plan of the lowered platform, which is for example nine hundred and thirty-eight millimeters from the rail.
Entre la traverse d'extrémité portée à hauteur normale et la partie surbaissée de la plateforme, la tête de chassis doit assurer le changement de niveau tout en garantissant un bon report des efforts de pression et traction notamment sur les longrines centrales de la plateforme.Between the end crossmember brought to normal height and the lowered part of the platform, the chassis head must ensure the level change while guaranteeing a good transfer of the pressure and traction forces, especially on the central sills of the platform.
A cet effet, on a généralement recours à une tête de chassis comprenant, attenant à la traverse d'extrémité des semelles horizontales inférieure et supérieure de longueur suffisante pour l'encadrement des organes de butée et d'amortissement de l'attelage automatique, lesquelles semelles sont reliées à la partie surbaissée de la plateforme par des poutres en col de cygne c'est à dire qui présentent deux arrondis opposés de rayon prôche de la moitié de différence de hauteur.For this purpose, use is generally made of a chassis head comprising, adjoining the end cross member of the lower and upper horizontal flanges of sufficient length for the framing of the abutment and damping members of the automatic coupling, which soles are connected to the lowered part of the platform by swan neck beams, that is to say which have two opposite rounded radii close to half the height difference.
Du fait de ces arrondis opposés, ces têtes de chassis ont l'inconvénient de s'étendre sur une hauteur importante.Due to these opposite rounding, these chassis heads have the disadvantage of extending over a significant height.
Aussi:
- d'une part, pour une même longueur hors tout de plateforme, cela pénalise la longueur de la partie surbaissée seule utilisable pour le chargement sur une hauteur maximale, et,
- d'autre part, le porte à faux de la traverse d'extrémité par rapport à l'axe du boggie et également trop important pour, en courbe de faible rayon garantir dans un plan horizontal la coopération de ses organes d'attelage avec ceux d'un wagon normal.As well:
on the one hand, for the same overall length of the platform, this penalizes the length of the lowered part alone, usable for loading to a maximum height, and,
- on the other hand, the overhang of the end cross member with respect to the axis of the bogie and also too large to, in a curve of small radius guarantee in a horizontal plane the cooperation of its coupling members with those of a normal wagon.
Ce porte à faux ne peut être réduit par écartement des boggies car on a vu que la distance entre boggies était limitée par le gabarit à respecter.This overhang cannot be reduced by spacing the bogies because we have seen that the distance between bogies was limited by the template to be respected.
Compte tenu de ces exigences contradictoires, on ne peut à ce jour sur une telle plateforme surbaissée placer bout à bout deux conteneurs du type dit "caisse mobile" faisant chacun sept mille huit cents millimètres de longueur.In view of these contradictory requirements, it is not possible to date on such a lowered platform place end to end two containers of the so-called "swap body" type each making seven thousand eight hundred millimeters in length.
D'autre têtes de chassis de plateforme surbaissée ont déjà été imaginées et notamment une plateforme (FR-A-2.061.193) dont les éléments de traction et de tamponnement sont portés par l'extrémité libre d'un panneau articulé par son extrémité opposée autour d'un axe porté horizontalement et transversalement par la plateforme de même qu'une plateforme (FR-A-2.026.167) dont l'association à la traverse d'extrémité s'opère par des supports réglables en hauteur.Other lowered platform chassis heads have already been imagined, and in particular a platform (FR-A-2,061,193), the traction and buffering elements of which are carried by the free end of a panel articulated by its opposite end. around an axis carried horizontally and transversely by the platform as well as a platform (FR-A-2,026,167) whose association with the end cross member is effected by supports adjustable in height.
Si elles permettent de réduire l'encombrement longitudinal de la liaison entre la traverse d'extrémité et la partie surbaissée ces solutions n'assurent que dans de mauvaises conditions le report vers la plateforme surbaissée des efforts dus à la traction et au tamponnement.If they make it possible to reduce the longitudinal size of the connection between the end crossmember and the lowered part, these solutions only ensure that, under poor conditions, the forces due to traction and buffering are transferred to the lowered platform.
L'invention a pour but de proposer une tête de chassis qui, tout en étant de longueur moindre que celle à poutres en col de cygne, assurent dans des conditions encore meilleures à celles-ci, le report des efforts de traction et de tamponnement. A cet effet, elle a pour objet un wagon à plateforme surbaissée du type cité plus haut, notamment caractérisé en ce qu'au lieu d'une tête de chassis comprenant une partie horizontale reliée à la partie surbaissée par des poutres en col de cygne, il comprend de manière connue pour une plateforme normale mais nouvelle pour une plateforme surbaissée, une structure en caisson dite "écharpe" formée :
- de deux plaques au moins sensiblement planes en forme sensiblement de trapèze dont la grande base qui est horizontale et transversale à la plateforme s'étand transversalement au moins jusqu'aux organes de tamponnement tandis que la petite base s'étand transversalement au moins jusqu'aux longrines centrales, lesquelles plaques relient, l'une dite supérieure, le bord supérieur de la traverse d'extrémité au bord de la semelle supérieure de la plateforme, l'autre dite inférieure le bord inférieur de la traverse d'extrémité au bord de la semelle inférieure de la plateforme,
- de nervures verticales reliant entre elles les deux plaques et s'étendant symétriquement depuis l'extrémité de l'une des longrines centrales jusque sur la traverse d'extrémité, dans le plan axial de l'une des organes de tamponnement, cette écharpe étant remarquable en ce qu'elle est inclinée longitudinalement.The object of the invention is to propose a chassis head which, while being of shorter length than that with swan neck beams, ensure in even better conditions the transfer of traction and buffering forces. To this end, it relates to a wagon with a lowered platform of the type mentioned above, in particular characterized in that instead of a chassis head comprising a horizontal part connected to the lowered part by swan neck beams, it comprises, in a known manner for a normal but new platform for a lowered platform, a box structure known as a "scarf" formed:
- of two at least substantially flat plates substantially in the shape of a trapezium, the large base of which is horizontal and transverse to the platform extends transversely at least to the buffering members while the small base extends transversely at least up to to the central sills, which plates connect, one said to be upper, the upper edge of the end crossmember to the edge of the upper sole of the platform, the other called lower the lower edge of the end crossmember to the edge of the bottom sole of the platform,
- vertical ribs connecting the two plates together and extending symmetrically from the end of one of the central sills to the end cross member, in the axial plane of one of the buffering members, this scarf being remarkable in that it is inclined longitudinally.

En se reportant au dessin, on voit que le wagon 1 comprend une plateforme 2 reposant sur les rails 3 par au moins deux boggies 4.Referring to the drawing, it can be seen that the
La plateforme 2 est constituée de longerons 5, 6 dont sur les bords des brancards 5 et entre eux des longrines 6 reliés par des traverses notamment d'extrémité 9, par exemple en U, pour former deux ailes supérieure 7 et inférieure 8 et présente une semelle inférieure 10 et une semelle supérieure 11 formant ou recevant un plancher.The

Le wagon objet de l'invention porte au moins à l'une de ses extrémités ses organes d'attelage et de tamponnement à une hauteur normale du rail, par exemple de mille deux cents millimètres et non sous le plan P de chargement qui est, par exemple à neuf cent trente huit millimètres du rail.The wagon which is the subject of the invention carries at least at one of its ends its coupling and buffering members at a normal height of the rail, for example one thousand two hundred millimeters and not under the loading plane P which is, for example nine hundred and thirty eight millimeters from the rail.
La partie de plateforme dite "tête de chassis" 17 située entre la traverse d'extrémité 9 et la partie surbaissée 18 de la plateforme 2 est conçue de manière à assurer le changement de niveau tout en garantissant un bon report des efforts de pression et de traction notamment sur les longrines 6 centrales à la plateforme.The part of the platform called "chassis head" 17 located between the
Au lieu d'une tête de chassis 17 comprenant une partie horizontale reliée à la partie surbaissée 18 par des poutres en col de cygne, la dite tête de chassis comprend de manière connue pour une plateforme normale mais nouvelle pour une plateforme surbaissée, une structure en caisson 20 dite "écharpe" formée :
- de deux plaques au moins sensiblement planes 21, 22 en forme sensiblement de trapèze dont la grande base qui est horizontale et transversale à la plateforme s'étand au moins jusqu'aux organes de tamponnement 13 tandis que la petite base s'étend au moins jusqu'aux longrines centrales 6, lesquelles plaques 21, 22 relient, l'une 21 dite supérieure, le bord supérieur 23 de la traverse d'extrémité au bord 24 de la semelle supérieure 11 de la plateforme, l'autre 22 dite inférieure le bord inférieur 25 de la traverse d'extrémité au bord 26 de la semelle inférieure 10 de la plateforme,
- de nervures verticales 27, 28 reliant entre elles les deux plaques et s'étendant symétriquement depuis l'extrémité 29, 30 de l'une des longrines centrales 6 jusque sur la traverse d'extrémité, dans le plan axial de l'un des organes de tamponnement, cette écharpe étant remarquable en ce qu'elle est inclinée longitudinalement.Instead of a

Selon l'invention, cette écharpe est caractérisée :
- d'une part, en ce que les plaques 21, 22 sont longitudinalement régulièrement inclinées et,
- d'autre part, en ce que la plaque supérieure 21 présente une découpe axiale débouchant au moins du côté de la grande base et recevant un boîtier 31 d'axe horizontal constituant intérieurement le logement 14 des organes 15, 16 de butée et d'amortissement de l'attelage automatique, lequel boîtier 31 est solidarisé à la plaque supérieure 21 par exemple par soudure.According to the invention, this scarf is characterized:

Selon une autre caractéristique de l'invention, entre, d'une part, les bords des longrines centrales 6 et semelles inférieure 22 et supérieure 21 et, d'autre part, l'écharpe 20 est intercalée une plaque verticale 32 qui se poursuit verticalement jusqu'en haut du boîtier sur l'extrémité duquel elle appuie de manière à former une butée 33 marquant la limite du plan de chargement P.According to another characteristic of the invention, between, on the one hand, the edges of the
Les parois latérales verticales 34, 35 du boîtier se raccordent avec les extrémités des longrines centrales et constituent des longrines de traction.The
De préférence, bien que cela ne soit pas nécessaire pour le report des efforts mais afin de favoriser la liaison aux brancards, au moins l'une des plaques inférieure et supérieure de l'écharpe 20 présente des prolongements latéraux 36, 37.Preferably, although this is not necessary for the transfer of the forces but in order to promote the connection to the stretchers, at least one of the lower and upper plates of the
La plaque inférieure 22 peut évidemment présenter des découpes 38 d'allègement et/ou d'accés à l'intérieur du caisson, par exemple pour les soudures et/ou la peinture.The
Avec une tête de chassis ainsi conçue, dans le cas d'une plateforme dont le plan de chargement était à neuf cent trente huit millimètres du rail et dont les organes de tamponnement étaient à mille deux cents millimètres du rail, d'excellents résultats dans le report des efforts ont été obtenus avec entre l'avant de la traverse d'extrémité et la face de butée 33 une longeur de mille cent soixante millimètres dictée par la longueur de l'encagement utile de l'attelage automatique (mille cent trente millimètres) et l'épaisseur de la plaque 32 (trente millimètres) ce qui, pour une plateforme hors tout de dix huit mille cent millimètres libère un plan de chargement de quinze mille sept cents millimètres de long et permet de placer sans problème deux caisses mobiles de sept mille huit cents millimètres de long.With a chassis head thus designed, in the case of a platform whose loading plane was nine hundred and thirty eight millimeters from the rail and whose buffering members were one thousand two hundred millimeters from the rail, excellent results in the transfer of efforts has been obtained with between the front of the end crossmember and the abutment face 33 a length of one thousand one hundred and sixty millimeters dictated by the length of the useful engagement of the automatic coupling (one thousand one hundred and thirty millimeters) and the thickness of the plate 32 (thirty millimeters) which, for an overall platform of eighteen thousand one hundred millimeters frees a loading plan of fifteen thousand seven hundred millimeters long and allows to place without problem two swap bodies of seven one thousand eight hundred millimeters long.
Cette réduction de la longueur de la tête de chassis permet par la même occasion de réduire son porte à faux par rapport à l'axe du boggie (dans l'exemple ci-dessus à deux mille trois cents millimètres).This reduction in the length of the chassis head makes it possible at the same time to reduce its overhang relative to the axis of the bogie (in the example above to two thousand three hundred millimeters).

cette écharpe étant remarquable en ce qu'elle est inclinée longitudinalement.- has a lower sole (10) and an upper sole (11) forming or receiving a floor,
in which platform, the end crosspieces are associated with the coupling (12) and buffering (13) members and behind each of which crosspieces is reserved a housing (14) of horizontal axis for the elements of the element coupling (12) which are its traction stop (15) and its shock absorber (16), which wagon carries at least at one of its ends its coupling and buffering members at a normal height of the rail, for example of one thousand two hundred millimeters and not under the loading plane P which is, for example nine hundred and thirty eight millimeters from the rail,
this wagon, the platform part called "chassis head" (17) located between the end crosspiece (9) and the lowered part (18) of the platform (2) is designed so as to ensure the level change while guaranteeing a good transfer of the pressure and traction forces, in particular on the sills (6) central to the platform, is CHARACTERIZED in that, instead of a chassis head (17) comprising a horizontal part connected to the part lowered (18) by swan neck beams, it comprises, in known manner for a normal but new platform for a lowered platform, a box structure (20) called "scarf" formed:
- two at least substantially flat plates (21, 22) in the form of a substantially trapezoid, the large base of which is horizontal and transverse to the platform extends at least to the buffering members (13) while the small base s 'extends at least to the central beams (6), which plates (21, 22) connect, one (21) called upper, the upper edge (23) of the end cross member to the edge (24) of the upper sole (11) of the platform, the other (22) called lower the lower edge (25) of the end cross member at the edge (26) of the lower sole (10) of the platform,
- vertical ribs (27, 28) connecting the two plates together and extending symmetrically from the end (29, 30) of one of the central beams (6) up to the end cross member, in the plane axial of one of the buffering members,
this scarf being remarkable in that it is inclined longitudinally.
- d'une part, en ce que les plaques (21, 22) sont longitudinalement régulièrement inclinées et,
- d'autre part, en ce que la plaque supérieure (21) présente une découpe axiale débouchant au moins du côté de la grande base et recevant un boîtier (31) d'axe horizontal constituant intérieurement le logement (14) d'encagement des organes (15, 16) de butée et d'amortissement de l'attelage automatique, lequel boîtier (31) est solidarisé à la plaque supérieure (21).2. Wagon according to claim 2 characterized:
- on the one hand, in that the plates (21, 22) are longitudinally regularly inclined and,
- on the other hand, in that the upper plate (21) has an axial cutout opening at least on the side of the large base and receiving a housing (31) of horizontal axis internally constituting the housing (14) for engaging the abutment and damping members (15, 16) of the automatic coupling, which housing (31) is secured to the upper plate (21).
