Description

L'invention porte sur un véhicule sur rails, notamment une voiture de chemin de fer à deux niveaux dont la-structure de la caisse est réalisée en matériaux différents. The invention relates to a rail vehicle, in particular a two-level railway car, the body structure of which is made of different materials.

Plusieurs sortes de métaux sont à l'heure actuelle utilisés pour, réaliser les structures de caisse, mais en général ces structures sont homogènes, par exemple caisse entièrement en aluminium ou entièrement en acier inoxydable ou entièrement en acier au cuivre ou entièrement en acier HLE. Several kinds of metals are currently used to make the body structures, but in general these structures are homogeneous, for example body entirely in aluminum or entirely in stainless steel or entirely in copper steel or entirely in HLE steel.

Les structures en alliage léger pour véhicule ferroviaire sont bien connues, elles se caractérisent par ltemploi de profilés filés de grandes dimensions permettant ainsi d'obtenir non seulement un gain de masse intéressant, mais aussi des économies de main-d'oeuvre d'assemblage. Par contre, certains des clients utilisateurs hésitent à adopter cette technique en raison de la moindre résistance au feu d'une telle structure
Certaines associations entre ces métaux existent néanmoins déjà : une voiture en acier inoxydable comporte en général des extrémités de châssis en acier au cuivre ou en acier
HLE. Par contre, aucune des techniques actuelles ne comporte de structure mixte où des parties en aluminium sont soudées, moyennant une interface spéciale à la structure en acier au cuivre ou autre acier allié.Light alloy structures for rail vehicles are well known, they are characterized by the use of large extruded sections thus making it possible to obtain not only an advantageous gain in mass, but also savings in assembly labor. On the other hand, some of the user customers are hesitant to adopt this technique because of the lower fire resistance of such a structure.
Certain associations between these metals nevertheless already exist: a stainless steel car generally has chassis ends made of copper steel or steel
HLE. On the other hand, none of the current techniques has a mixed structure where aluminum parts are welded, by means of a special interface to the structure made of copper steel or other alloy steel.

Par ailleurs, les voitures à deux niveaux les plus récentes comportent un plancher intermédiaire en composite aluminium, à coeur en nids d'abeille, -qui doit être fixé sur les faces moyennant un dispositif d'assemblage tel que rivets ou vis. Ce plancher ne fait donc pas partie de la structure de caisse proprement dite et ne participe pas obligatoirement aux efforts pour les calculs de résistance, de plus le système d'assemblage peut présenter des défauts de résistance à la corrosion dûs au couple acier-aluminium. Furthermore, the most recent two-level cars have an intermediate floor made of aluminum composite, with a honeycomb core, which must be fixed to the faces by means of an assembly device such as rivets or screws. This floor is therefore not part of the body structure proper and does not necessarily participate in the efforts for strength calculations, moreover the assembly system may have corrosion resistance defects due to the steel-aluminum couple.

En outre, les impératifs de construction de gabarit, notamment les hauteurs d'habitacles, limitent l'épaisseur disponible pour les planchers. Ceci exclut la possibilité de monter des planchers à traverses et panneaux suffisamment résistants.  In addition, the size construction requirements, including cabin heights, limit the thickness available for floors. This excludes the possibility of mounting floors with transoms and panels that are sufficiently resistant.

Pour résoudre ce problème, il existe des planchers de faible épaisseur, réalisés en ondulés, présentant une bonne rigidité transversale mais une certaine souplesse longitudinale, et de ce fait, ils ne sont pas capables de résister aux efforts longitudinaux. To solve this problem, there are thin floors, made of corrugated, having good transverse rigidity but a certain longitudinal flexibility, and therefore they are not able to withstand the longitudinal forces.

Pour pallier tous les inconvénients des techniques précitées, la demanderesse s'est imposée un double but, réaliser d'une part une structure mixte, en acier pour les faces et le pavillon, et en aluminium pour les planchers cette structure mixte devant d'autre part se comporter comme une caisse unique homogène face aux différents efforts, imposés par les essais de contrainte rencontrés en service charges verticales et efforts de compression. To overcome all the drawbacks of the aforementioned techniques, the applicant has set itself a double goal, to produce on the one hand a mixed structure, in steel for the faces and the roof, and in aluminum for the floors, this mixed structure in front of other share behave like a single body homogeneous in the face of the various forces imposed by the stress tests encountered in vertical loads and compression forces service.

La caisse de voiture conforme à l'invention comporte au moins un niveau d'habitacle, elle est de structure mixte comportant un pavillon, au moins un plancher, des faces constituées de montants verticaux en acier portant des longrines en acier et un habillage, caractérisée en ce qu'elle comporte au moins un plancher composé de plaques en aluminium filé, soudées sur des dispositifs d'encastrement constitués au moins de
- un support solidaire d'une face de la caisse,
- deux éléments cofilés en forme de bandes aluminiumacier, les côtés acier de ces bandes étant soudés sur le support, les côtés aluminium étant soudés sur un plancher en aluminium et de part et d'autre de celui-ci.The car body according to the invention comprises at least one level of passenger compartment, it is of mixed structure comprising a flag, at least one floor, faces made up of vertical steel uprights carrying steel sills and a covering, characterized in that it comprises at least one floor made up of spun aluminum plates, welded to embedding devices made up of at least
- a support integral with one face of the body,
- two co-formed elements in the form of aluminum steel strips, the steel sides of these strips being welded to the support, the aluminum sides being welded to and on either side of an aluminum floor.

Plus particulièrement selon un premier mode de réali- sation, le support est composé d'une longrine longitudinale, de section sensiblement en oméga, comportant deux bandes longitudinales soudées sur les montants de la structure et une face proéminente coopérant à au moins une ferrure de liaison par soudure. More particularly according to a first embodiment, the support is composed of a longitudinal sill, of section substantially in omega, comprising two longitudinal strips welded on the uprights of the structure and a prominent face cooperating with at least one connecting fitting. by welding.

Selon un deuxième mode de réalisation, le support est composé d'un longeron longitudinal comportant au moins une bordure soudée aux montants de la structure d'une face, et au moins une ferrure de liaison soudée sur le longeron.  According to a second embodiment, the support is composed of a longitudinal spar comprising at least one edge welded to the uprights of the structure of a face, and at least one connecting fitting welded to the spar.

La technique nouvelle, objet du dépôt de la présente demande de brevet, utilise l'aluminium pour les parties inférieures de caisse qui ne sont pas exposées à des températures très élevées lors d'u-n incendie. De plus, le plancher intermédiaire entre les deux niveaux est également constitué en aluminium, soudé moyennant une interface spéciale sur les faces du véhicule. L'ensemble de ces différentes parties constitue un assemblage soudé qui permet de considérer le plancher intermédiaire comme un élément résistant totalement intégré dans la structure de caisse et dont on peut tenir compte lors du calcul de résistance par éléments finis. The new technique, the subject of the filing of this patent application, uses aluminum for the lower body parts which are not exposed to very high temperatures during a fire. In addition, the intermediate floor between the two levels is also made of aluminum, welded by means of a special interface on the sides of the vehicle. All of these different parts constitute a welded assembly which makes it possible to consider the intermediate floor as a resistant element fully integrated into the body structure and which can be taken into account when calculating resistance by finite elements.

La figure 1 est une coupe transversale d'une caisse de voiture de chemin de fer à deux niveaux, objet de l'invention. Figure 1 is a cross section of a two-level railway car body, object of the invention.

La figure 2 est une coupe longitudinale selon le plan DD de la figure 1. FIG. 2 is a longitudinal section along the plane DD of FIG. 1.

La structure de la caisse représentée à la figure 1 se compose principalement de deux faces (1), d'un pavillon (2), d'un plancher inférieur (3), d'un plancher intermédiaire (4), de dispositifs (5) pour réaliser l'encastrement des planchers (3, 4) sur les faces (1). The body structure shown in Figure 1 mainly consists of two faces (1), a pavilion (2), a lower floor (3), an intermediate floor (4), devices (5 ) to embed the floors (3, 4) on the faces (1).

Les faces (1) sont constituées de façon classique, par des montants verticaux (6) portant des longrines longitudinales et un habillage. The faces (1) are constituted in a conventional manner, by vertical uprights (6) carrying longitudinal sills and a covering.

Les planchers intermédiaire (4) et inférieur (3) sont en aluminium filé, le premier (4) par des éléments' dont le sens du filage est transversal pour mieux résister aux charges verticaux, le second (3) par des éléments dont le sens du filage est longitudinal pour mieux résister aux efforts de compression.  The intermediate (4) and lower (3) floors are in spun aluminum, the first (4) by elements' whose direction of spinning is transverse to better resist vertical loads, the second (3) by elements whose direction spinning is longitudinal to better withstand compression forces.

A titre d'exemples non limitatifs, la figure 3 représente un dispositif d'encastrement (5) du plancher intermédiaire (4) qui est composé
- d'une longrine (7) de section dite en oméga, dont les bordures (7a) sont soudées sur les montants (6), s'étendant sur toute la longueur de la caisse,
- de ferrures d'assemblage (9a, 9b) soudées sur la face proéminente de la longrine (7),
- de deux éléments en cofilé (8a, 8b) c'est-à-dire des bandes métalliques aluminium-acier inoxydable. Les côtés acier inoxydable de ces bandes sont soudés sur les ferrures d'assemblage (9a, 9b), les côtés aluminium sur le plancher intermédiaire (4) en aluminium et de part et d'autre de celui-ci.By way of nonlimiting examples, FIG. 3 represents an embedding device (5) of the intermediate floor (4) which is composed
- a sill (7) of so-called omega section, the edges (7a) of which are welded to the uprights (6), extending over the entire length of the body,
- assembly fittings (9a, 9b) welded to the prominent face of the sill (7),
- two co-threaded elements (8a, 8b), that is to say aluminum-stainless steel metal strips. The stainless steel sides of these strips are welded on the assembly fittings (9a, 9b), the aluminum sides on the intermediate floor (4) in aluminum and on either side thereof.

Ces deux éléments (8a, 8b) jouent le rôle d'interface pour 1' assemblage.  These two elements (8a, 8b) act as an interface for the assembly.

La figure 4 montre à titre d'exemple non limitatif un dispositif d'encastrement du plancher inférieur (3) dont le principe est analogue à celui de la figure 3 avec un longeron (10) comportant une bordure (10a) soudée au montant (6), une ferrure d'assemblage (9c), une interface composée de deux éléments en cofilé (8c, 8d).  FIG. 4 shows by way of nonlimiting example a device for embedding the lower floor (3), the principle of which is similar to that of FIG. 3 with a spar (10) comprising an edge (10a) welded to the upright (6 ), an assembly fitting (9c), an interface composed of two co-wired elements (8c, 8d).

Le nouveau dispositif d'encastrement (5) décrit ci-dessus permet d'éliminer les liaisons de type rivets ou vis au profit de liaisons soudées, de réaliser un bon encastrement du plancher par rapport à la face, d'éviter les problèmes de corrosion. The new embedding device (5) described above makes it possible to eliminate rivet or screw type connections in favor of welded connections, to achieve good embedding of the floor relative to the face, to avoid corrosion problems. .

Cette technique nouvelle permet d'obtenir dans des conditions de résistance identiques par rapport à la solution conventionnelle à structure homogène en acier, une importante économie de masse, environ 15 S de la masse totale de la structure.  This new technique makes it possible to obtain, under identical resistance conditions compared to the conventional solution with a homogeneous steel structure, a significant saving in mass, approximately 15% of the total mass of the structure.

Bien entendu les modes de-réalisation représentés aux figures 3 et 4 sont des exemples non limitatifs du dispositif d'encastrement (5) qui peut présenter des variantes d'exécution par exemple au niveau de la forme, des dimensions ou du nombre des pièces. Of course the embodiments shown in Figures 3 and 4 are non-limiting examples of the embedding device (5) which may have alternative embodiments for example in terms of shape, dimensions or number of parts.

Ce dispositif d'encastrement (5) peut être envisagé pour un seul des deux planchers ou pour les deux, il peut également être utilisé sur d-es voitures à un seul niveau, et sur tout type de véhicules sur rails, par exemple voitures de chemin de fer, tramway, métro...  This embedding device (5) can be envisaged for only one of the two floors or for both, it can also be used on single-level cars, and on all types of rail vehicles, for example passenger cars. rail, tram, metro ...
