Abstract
Description
La présente invention concerne une paroi latérale pour caisse de véhiculeThe present invention relates to a side wall for a vehicle body
ferroviaire comprenant une ossature de support métallique et un habillage extérieur railway including a metal support frame and an exterior cladding
métallique soudé sur l'ossature.metal welded to the frame.
L'invention s'applique en particulier aux caisses The invention applies in particular to cases
de véhicules ferroviaires réalisées en acier. of railway vehicles made of steel.
La tendance actuelle pour améliorer l'aspect visuel des véhicules ferroviaires est de réaliser des parois The current trend to improve the visual appearance of railway vehicles is to make walls
latérales à faces extérieures lisses. sides with smooth outer faces.
L'aluminium permet de réaliser, grâce à des pièces profilées, de telles parois avec un aspect visuel satisfaisant. Cependant, l'utilisation de l'aluminium pour les véhicules ferroviaires a pour conséquence un surcoût substantiel par rapport à l'utilisation de Aluminum allows such walls to be produced with profiled parts with a satisfactory visual appearance. However, the use of aluminum for rail vehicles results in a substantial additional cost compared to the use of
l'acier.steel.
En revanche, dans le cas de l'acier, l'obtention d'un habillage présentant un aspect visuel satisfaisant pose de nombreux problèmes, en particulier du fait des techniques de soudage classiquement utilisées dans le domaine ferroviaire. En effet, l'utilisation du soudage à l'arc, fortement énergétique, pour souder des tôles constituant l'habillage sur l'ossature de support, induit des déformations importantes dans ces tôles d'habillage, de sorte que le temps passé à les redresser a un impact important sur le coût de fabrication des On the other hand, in the case of steel, obtaining a covering having a satisfactory visual appearance poses many problems, in particular due to the welding techniques conventionally used in the railway field. Indeed, the use of arc welding, highly energetic, to weld sheets constituting the covering on the support frame, induces significant deformations in these covering sheets, so that the time spent in straightening has a significant impact on the manufacturing cost of
véhicules ferroviaires.railway vehicles.
Par ailleurs, le soudage par points résistifs provoque le marquage de la face extérieure des tôles d'habillage, au niveau des points de contact entre ces tôles et les électrodes de soudage. En outre, ce type de soudage est prohibé par certains pays et/ou certaines entreprises. L'invention a pour but de résoudre ces problèmes en fournissant une paroi latérale pour véhicule ferroviaire permettant de répondre de manière économique aux Furthermore, resistive spot welding causes the marking of the outer face of the covering sheets, at the contact points between these sheets and the welding electrodes. In addition, this type of welding is prohibited by certain countries and / or certain companies. The object of the invention is to solve these problems by providing a side wall for a rail vehicle making it possible to respond economically to
contraintes d'aspect visuel mentionnées ci-dessus. visual appearance constraints mentioned above.
A cet effet, l'invention a pour objet une paroi latérale pour caisse de véhicule ferroviaire comprenant une ossature de support métallique et un habillage extérieur métallique soudé sur l'ossature, caractérisée en ce qu'au moins certaines soudures reliant l'habillage à l'ossature sont des soudures laser réalisées dans des zones de chevauchement entre l'ossature et l'habillage, en ce que ces soudures sont obtenues par transparence à partir de la face intérieure de la paroi latérale, au travers d'éléments de l'ossature de support, et en ce que ces soudures sont des soudures non-débouchantes dans To this end, the subject of the invention is a side wall for a rail vehicle body comprising a metal support frame and a metallic external covering welded to the framework, characterized in that at least some welds connecting the covering to the frame are laser welds made in overlapping zones between the frame and the covering, in that these welds are obtained by transparency from the inner face of the side wall, through elements of the frame support, and in that these welds are non-through welds in
la face extérieure de la paroi latérale. the outer face of the side wall.
Selon des modes particuliers de réalisation, la paroi latérale peut comprendre l'une ou plusieurs des caractéristiques suivantes, prises isolément ou en combinaison: - elle comprend un battant de pavillon destiné à être relié au pavillon d'une caisse de véhicule ferroviaire, et des éléments de l'ossature de support sont reliés au battant de pavillon par des soudures laser réalisées dans des zones de chevauchement entre ces éléments et le battant de pavillon, ces soudures sont obtenues par transparence à partir de la face intérieure de la paroi latérale, au travers d'éléments de l'ossature, et ces soudures sont non-débouchantes dans la face extérieure de la paroi latérale; et - ces soudures laser sont des soudures According to particular embodiments, the side wall may include one or more of the following characteristics, taken individually or in combination: - it includes a roof leaf intended to be connected to the roof of a rail vehicle body, and elements of the support frame are connected to the roof wing by laser welds produced in overlapping zones between these elements and the roof wing, these welds are obtained by transparency from the inner face of the side wall, at the through elements of the frame, and these welds are non-emerging in the outer face of the side wall; and - these laser welds are welds
structurantes de transmission d'effort. structuring of force transmission.
L'invention a également pour objet une caisse de véhicule ferroviaire, caractérisée en ce qu'elle The invention also relates to a rail vehicle body, characterized in that it
comprend deux parois latérales telles que définies ci- includes two side walls as defined above
dessus.above.
L'invention sera mieux comprise à la lecture de la The invention will be better understood on reading the
description qui va suivre, donnée uniquement à titre description which follows, given only as
d'exemple, et faite en se référant aux dessins annexés, sur lesquels: - La figure 1 est une section transversale et schématique d'une caisse de véhicule ferroviaire selon l'invention; - La figure 2 est une vue partielle, schématique et en perspective extérieure d'une paroi latérale de la caisse de la figure 1; - La figure 3 est une vue partielle, schématique, avec arrachement partiel et en perspective intérieure de la paroi de la figure 2; et - Les figures 4 et 5 sont des sections schématiques, partielles, prises respectivement suivant example, and made with reference to the accompanying drawings, in which: - Figure 1 is a cross section and schematic of a rail vehicle body according to the invention; - Figure 2 is a partial schematic view in external perspective of a side wall of the box of Figure 1; - Figure 3 is a partial, schematic view, partially broken away and inside perspective of the wall of Figure 2; and - Figures 4 and 5 are schematic, partial sections, taken respectively according to
les lignes IV-IV et V-V de la figure 3. lines IV-IV and V-V in Figure 3.
La figure 1 représente schématiquement une caisse 1 de véhicule ferroviaire réalisée en acier et qui comprend essentiellement un châssis 2, un toit ou pavillon 3 et deux parois latérales 4 chacune de FIG. 1 schematically represents a body 1 of a railway vehicle made of steel and which essentially comprises a chassis 2, a roof or roof 3 and two side walls 4 each of
concavité dirigée vers l'intérieur de la caisse 1. concavity directed towards the interior of the body 1.
Les parois 4 étant symétriques l'une de l'autre par rapport à un plan longitudinal médian de la caisse 1, The walls 4 being symmetrical to each other with respect to a median longitudinal plane of the body 1,
une seule sera décrite ci-après.only one will be described below.
Comme illustré par les figures 1 à 3, la paroi 4 comprend essentiellement un longeron inférieur longitudinal 6 (en bas sur les figures 1 et 3), une ossature de support 8, une partie supérieure arquée d'habillage ou battant de pavillon 10 et un habillage extérieur 12, qui s'étend entre le longeron 6 et le battant de pavillon 10 et dont la face extérieure 13 est As illustrated by FIGS. 1 to 3, the wall 4 essentially comprises a longitudinal lower spar 6 (at the bottom in FIGS. 1 and 3), a support frame 8, an upper arched part of the covering or flying the roof 10 and external covering 12, which extends between the side member 6 and the wing 10 and the external face 13 of which is
lisse.smooth.
Le longeron 6 relie le châssis 2 à la paroi 4. Le battant de pavillon 10 relie le pavillon 3 à la paroi The longitudinal member 6 connects the chassis 2 to the wall 4. The wing 10 connects the roof 3 to the wall
latérale 4.lateral 4.
L'ossature 8 en acier comprend essentiellement des montants 14 et des profilés longitudinaux ou longrines The steel frame 8 essentially comprises uprights 14 and longitudinal or beam profiles
16 orthogonales aux montants 14.16 orthogonal to the uprights 14.
Les montants 14 sont des profilés en U (figure 4) de forte épaisseur (3 à 5 mm) dont les extrémités inférieures (en bas sur la figure 3) sont fixées, par exemple par soudage MIG (Metal Inert Gas), sur le longeron 6 et dont les extrémités supérieures sont soudées sur le battant de pavillon 10, comme décrit ultérieurement. Ces montants 14 sont disposés régulièrement le long de la paroi latérale 4 et sensiblement orthogonalement The uprights 14 are very thick U-shaped profiles (FIG. 4) (3 to 5 mm), the lower ends of which (at the bottom in FIG. 3) are fixed, for example by MIG (Metal Inert Gas) welding, to the spar. 6 and whose upper ends are welded to the wing 10, as described later. These uprights 14 are arranged regularly along the side wall 4 and substantially orthogonally
au longeron 6.to the side member 6.
Les longrines 16 sont des profilés de forte épaisseur (3 à 5 mm) et de section courante en Q (figure ). Les éléments 14 et 16 de l'ossature 8 sont assemblés entre eux, par exemple par soudage MIG, au niveau de leurs zones de rencontre en formant des noeuds d'assemblage. Ces éléments 10 et 12 sont par ailleurs emboutis et découpés au niveau de ces noeuds d'assemblage pour présenter des surfaces planes de pose The sills 16 are very thick sections (3 to 5 mm) and of common section in Q (figure). The elements 14 and 16 of the framework 8 are assembled together, for example by MIG welding, at their meeting areas by forming assembly nodes. These elements 10 and 12 are also stamped and cut at these assembly nodes to present flat laying surfaces.
de l'habillage 12.dressing 12.
L'habillage extérieur 12 comprend, par exemple, des tôles fines en acier assemblées entre elles par soudage bord à bord. L'épaisseur de ces tôles est typiquement The outer covering 12 comprises, for example, thin steel sheets assembled together by edge-to-edge welding. The thickness of these sheets is typically
inférieure à 3 mm.less than 3 mm.
L'habillage 12 est prédécoupé pour ménager des The covering 12 is pre-cut to spare
ouvertures 19 pour des fenêtres.openings 19 for windows.
L'habillage 12 est disposé sur le côté extérieur de l'ossature 8 et il est fixé sur les montants 14 par des cordons de soudure laser 20. Comme illustré par la figure 4, ces cordons de soudure laser 20 sont réalisés dans des zones de chevauchement 21 entre l'habillage 12 et les âmes centrales planes 22 des montants 14. Ces cordons de soudure 20 sont obtenus par transparence à partir de la face intérieure 24 de la paroi latérale 4 (en bas sur la figure 4). En d'autres termes, un faisceau laser est venu traverser l'âme 22 du montant 14 pour ensuite faire fondre localement l'habillage 12 et ainsi souder le montant 14 et l'habillage 12 au niveau de leurs surfaces en regard dans la zone de chevauchement 21. Ainsi, chaque cordon de soudure 20 traverse totalement l'âme 22 correspondante puis 315 partiellement l'habillage 12 chevauchant l'âme 22. Ces cordons de soudure 20 sont non-débouchants dans la face The covering 12 is arranged on the outside of the framework 8 and it is fixed to the uprights 14 by laser welding cords 20. As illustrated in FIG. 4, these laser welding cords 20 are produced in areas of overlap 21 between the covering 12 and the flat central cores 22 of the uprights 14. These weld beads 20 are obtained by transparency from the inner face 24 of the side wall 4 (below in FIG. 4). In other words, a laser beam has come through the core 22 of the upright 14 and then locally melt the covering 12 and thus weld the upright 14 and the covering 12 at their facing surfaces in the area of overlap 21. Thus, each weld bead 20 completely crosses the corresponding core 22 and then 315 partially the covering 12 overlapping the core 22. These weld beads 20 are non-opening in the face
extérieure 13 de l'habillage 12.exterior 13 of the covering 12.
De manière analogue, l'habillage 12 est fixé sur les longrines 16 par des cordons de soudure laser 26 réalisés dans des zones de chevauchement 27 entre les pattes 28 latérales des longrines 16 et l'habillage 12. Les pattes 28 ont été agrandies sur la figure 3 pour plus de clarté. Ces cordons de soudure 26 sont réalisés par transparence à partir de la face intérieure 24 de la Similarly, the covering 12 is fixed to the sills 16 by laser welding seams 26 produced in overlapping zones 27 between the lateral tabs 28 of the sills 16 and the covering 12. The tabs 28 have been enlarged on the Figure 3 for clarity. These weld beads 26 are produced by transparency from the inner face 24 of the
paroi 4 (à droite sur la figure 5) et sont non- wall 4 (on the right in figure 5) and are not
débouchants dans la face extérieure 13 de l'habillage opening into the outer face 13 of the covering
12.12.
Comme illustré schématiquement par arrachement sur la figure 3, les montants 14 sont soudés sur le battant de pavillon 10 en des zones de chevauchement 30 entre ce dernier et les montants 14, par prolongement des cordons As illustrated diagrammatically by cutaway in FIG. 3, the uprights 14 are welded to the wing 10 in overlapping zones 30 between the latter and the uprights 14, by extension of the beads
de soudure 20.solder 20.
Enfin, l'habillage 12 est soudé le long de sa partie inférieure sur le longeron 6, par exemple par soudage MIG. Ce soudage, effectué après le soudage de l'habillage 12 sur l'ossature 8, induit des déformations limitées du fait de la rigidité conférée à l'habillage Finally, the covering 12 is welded along its lower part to the beam 6, for example by MIG welding. This welding, carried out after the welding of the covering 12 on the framework 8, induces limited deformations due to the rigidity imparted to the covering.
12 par l'ossature 8.12 by frame 8.
Les cordons de soudure 20 et 26, reliant l'habillage 12 à l'ossature 8, sont des soudures structurantes de transmission d'effort. Ainsi l'habillage 12 participe, avec l'ossature 8, à la rigidification de la paroi latérale 4 et donc de la The weld beads 20 and 26, connecting the covering 12 to the framework 8, are structuring welds of force transmission. Thus the covering 12 participates, with the framework 8, in the stiffening of the side wall 4 and therefore of the
caisse 1.box 1.
La structure décrite ci-dessus permet d'obtenir de manière relativement économique des parois latérales 4 à The structure described above makes it possible to obtain relatively economically side walls 4 to
face extérieure 13 lisse.outer face 13 smooth.
En effet, le type de soudage choisi permet de limiter les déformations induites dans l'habillage 12 lors de son soudage sur l'ossature 8. Ainsi, les opérations nécessaires pour rétablir un aspect visuel satisfaisant sont limitées; les cordons de soudure 20 et 26 non- débouchants, ne marquent pas la face extérieure 13 de la paroi 4, ce qui permet d'obtenir l'aspect visuel recherché. Par ailleurs, la structure choisie de la paroi latérale 4 permet l'assemblage automatisé de ces parois en des temps relativement réduits, le soudage laser permettant d'atteindre des Indeed, the type of welding chosen makes it possible to limit the deformations induced in the covering 12 when it is welded to the frame 8. Thus, the operations necessary to restore a satisfactory visual appearance are limited; the non-opening weld beads 20 and 26 do not mark the outer face 13 of the wall 4, which makes it possible to obtain the desired visual appearance. Furthermore, the chosen structure of the side wall 4 allows the automated assembly of these walls in relatively short times, the laser welding making it possible to reach
vitesses de soudage de 20 m/mn.welding speeds of 20 m / min.
Selon des variantes non représentées, les cordons de soudure 20 et 26 peuvent être discontinus et l'emploi du soudage laser peut être limité aux zones nécessaires According to variants not shown, the weld beads 20 and 26 can be discontinuous and the use of laser welding can be limited to the necessary areas
pour assurer un aspect visuel satisfaisant. to ensure a satisfactory visual appearance.
