Description

La présente invention concerne un véhicule ferroviaire comprenant aux moins une voiture, chaque voiture comprenant une caisse de voiture, la caisse étant supportée par au moins un bogie comprenant des coussins d'air et des longerons. La caisse et le bogie sont liés entre eux par au moins une traverse de charge.The present invention relates to a railway vehicle comprising at least one car, each car comprising a car body, the body being supported by at least one bogie comprising air cushions and longitudinal members. The body and the bogie are interconnected by at least one load beam.

L'invention s'applique plus particulièrement aux véhicules ferroviaires du type métro, trains interrégionaux et autres.The invention applies more particularly to railway vehicles of the subway type, interregional trains and others.

Pour faciliter le processus de fabrication d'un bogie, il est connu d'utiliser des composants en fonte. Par rapport au composants en acier, en acier mécano-soudé ou moulé, la fonte comporte des caractéristiques avantageuses concernant sa coulabilité pendant le processus de fabrication. Ainsi, la fonte permet de réaliser des pièces présentant des formes plus complexes d'un seul tenant.To facilitate the process of manufacturing a bogie, it is known to use cast iron components. Compared to the steel, steel-welded or cast steel components, the cast iron has advantageous characteristics regarding its flowability during the manufacturing process. Thus, the cast makes it possible to produce parts having more complex shapes in one piece.

Il a été proposé, par exemple dans le document DE 10 200 602 98 35 , de fournir, dans un véhicule ferroviaire, un composant de la caisse en fonte afin de faciliter le processus de fabrication. Ce composant est la traverse reliant les deux longerons de la caisse du véhicule et supportant le bogie.It has been proposed, for example in the document DE 10 200 602 98 35 , to provide, in a railway vehicle, a component of the cast iron crate to facilitate the manufacturing process. This component is the crossbar connecting the two longitudinal members of the vehicle body and supporting the bogie.

Dans un bogie, plusieurs composants actifs sont intégrés, par exemple des moteurs pour entrainer le véhicule, des systèmes d'alimentation d'air et autres. Dans le type de véhicule ferroviaire précité, en général, il est désirable d'avoir un plancher très bas afin de mettre à disposition un maximum d'espace pour les passagers. En conséquence, un espace faible et limité par ces contraintes est disponible pour intégrer la traverse qui lie le bogie à la caisse, ainsi que très peu de place est disponible pour réaliser la connexion des composants actifs du bogie sur la traverse.In a bogie, several active components are integrated, for example engines for driving the vehicle, air supply systems and the like. In the aforementioned type of railway vehicle, in general, it is desirable to have a very low floor in order to provide a maximum of space for the passengers. As a result, a small space limited by these constraints is available to integrate the crossbar which links the bogie to the body, and very little space is available to connect the active components of the bogie to the crosshead.

L'un des buts de l'invention est de pallier ces inconvénients en proposant un véhicule ferroviaire présentant une liaison entre une caisse et un bogie permettant l'intégration simple de composants actifs.One of the aims of the invention is to overcome these disadvantages by proposing a railway vehicle having a connection between a body and a bogie allowing the simple integration of active components.

A cet effet, l'invention concerne un véhicule ferroviaire du type précité, dans lequel la traverse de charge est fixée sous la caisse du véhicule ferroviaire et repose sur les coussins d'air et dans lequel la traverse de charge est réalisée en fonte.To this end, the invention relates to a railway vehicle of the aforementioned type, wherein the load crossbar is fixed under the body of the railway vehicle and rests on the air cushions and wherein the load crossbar is made of cast iron.

Le fait que la traverse de charge est fixée sous la caisse et repose sur les coussins d'air permet d'économiser de l'espace dans le bogie. En conséquence, plus d'espace est disponible dans le bogie pour accueillir des composants actifs. En outre, le fait de réaliser la traverse de charge en fonte réduit le poids de la traverse et permet de lui conférer une forme plus complexe.The fact that the load crossbar is fixed under the body and rests on the air cushions saves space in the bogie. As a result, more space is available in the bogie to accommodate active components. In addition, the fact of making the cast iron crosshead reduces the weight of the cross and allows to give it a more complex shape.

Dans la description, les termes « sur », « sous », « au-dessus », « en-dessous » sont définis par rapport à une direction d'élévation d'un véhicule ferroviaire lorsqu'il est disposé sur des rails, c'est-à-dire une direction sensiblement verticale lorsque le train circule sur des rails horizontaux. La direction longitudinale est définie par la direction de circulation du véhicule ferroviaire et la direction transversale est la direction sensiblement perpendiculaire à la direction longitudinale et à la direction d'élévation du véhicule ferroviaire.In the description, the terms "on", "under", "above", "below" are defined with respect to a direction of elevation of a railway vehicle when it is arranged on rails, c. that is to say a substantially vertical direction when the train is traveling on horizontal rails. The longitudinal direction is defined by the direction of circulation of the railway vehicle and the transverse direction is the direction substantially perpendicular to the longitudinal direction and the direction of elevation of the railway vehicle.

En référence aux figures 1 à 3, on décrit un bogie comprenant deux longerons 3a, 3b qui s'étendent selon la direction longitudinale et qui supportent des essieux non représentés. Les longerons 3a, 3b portent au moins un coussin d'air 1a, 1b chacun, le coussin d'air 1a, 1b sensiblement au centre des longerons 3a, 3b selon la direction longitudinale. En outre, les longerons 3a, 3b sont, aux extrémités longitudinales et à leur centre, connectés par des traverses 5a, 5b et 5c l'une à l'autre. Les traverses 5a, 5b et 5c s'étendent sensiblement selon une direction transversale perpendiculaire par rapport à la direction longitudinale. La traverse 5c assure la liaison avec un pivot 7. En outre, le bogie comprend un ou plusieurs composants actifs, par exemple un moteur, un système d'alimentation d'air et autre.With reference to Figures 1 to 3 , a bogie comprising two longitudinal members 3a, 3b which extend in the longitudinal direction and which support unrepresented axles. The longitudinal members 3a, 3b carry at least one air cushion 1a, 1b each, the air cushion 1a, 1b substantially in the center of the longitudinal members 3a, 3b in the longitudinal direction. In addition, the longitudinal members 3a, 3b are, at the longitudinal ends and at their center, connected by cross members 5a, 5b and 5c to one another. The crosspieces 5a, 5b and 5c extend substantially in a transverse direction perpendicular to the longitudinal direction. The cross member 5c provides the connection with a pivot 7. In addition, the bogie comprises one or more active components, for example a motor, an air supply system and the like.

La structure du bogie n'est donnée qu'à titre d'exemple et pourrait être différente. Par exemple, le bogie pourrait être formé par deux demi-châssis articulés entre eux et supportant chacun un essieu.The bogie structure is only given as an example and could be different. For example, the bogie could be formed by two half-frames hinged together and each supporting an axle.

Les coussins d'air 1a, 1b, ou coussins pneumatiques, qui sont fixés au bogie, supportent une traverse de charge 2. La traverse de charge 2 s'étend sensiblement selon la direction transversale au-dessus du bogie. Les coussins d'air sont aptes à atténuer des mouvements verticaux d'une caisse 9 et se comportent donc comme un amortisseur.The air cushions 1a, 1b, or pneumatic cushions, which are fixed to the bogie, support a load crossbar 2. The load crossbar 2 extends substantially in the transverse direction above the bogie. The air cushions are capable of attenuating vertical movements of a box 9 and therefore behave like a shock absorber.

La traverse de charge 2 est moulée en fonte, par exemple fonte graphite sphéroïdale. De préférence, elle est faite en une seule pièce, ce que permet le fait de réaliser la traverse en fonte.The load beam 2 is molded of cast iron, for example spheroidal graphite cast iron. Preferably, it is made in one piece, which allows the realization of the cast iron cross.

La traverse de charge 2 est, entre autres, liée par des amortisseurs 4a, 4b au bogie, les amortisseurs s'étendant sensiblement selon la direction d'élévation. En outre, la traverse 2 est reliée au bogie par le pivot 7, des bielles antiroulis 6a, 6b, les bielles s'étendant sensiblement selon la direction d'élévation. Les bielles antiroulis 6a, 6b comprennent deux articulations chacune, une articulation liant la bielle 6a, 6b à la traverse de charge 2, l'autre articulation liant la bielle 6a, 6b au bogie. Les axes des articulations s'étendent sensiblement selon la direction transversale.The load crossbar 2 is inter alia bound by dampers 4a, 4b to the bogie, the dampers extending substantially in the direction of elevation. In addition, the cross member 2 is connected to the bogie by the pivot 7, anti-roll rods 6a, 6b, connecting rods extending substantially in the direction of elevation. The antiroll rods 6a, 6b comprise two joints each, an articulation linking the connecting rod 6a, 6b to the load crossbar 2, the other link connecting the connecting rod 6a, 6b to the bogie. The axes of the joints extend substantially in the transverse direction.

La traverse de charge 2 comprend à chacune de ses extrémités transversales deux surfaces de fixation 8a, 10 a et 8b, 10b formant entre elles un angle. Dans un mode de réalisation préféré, les deux surfaces de fixation sont perpendiculaires l'une par rapport à l'autre respectivement. La traverse de charge 2 est fixée par ces surfaces de fixation 8a, 8b, 10a, 10b à la caisse 9 du véhicule ferroviaire. La caisse 9 du véhicule est par exemple de matériau aluminium. La fixation entre la traverse de charge 2 en fonte et la caisse 9 est de préférence effectuée par des rivets ou tout autre moyen de fixation techniquement possible. Cependant, la fixation n'est pas effectuée par soudage du fait de l'hétérogénéité des matériaux assemblés.The load beam 2 comprises at each of its transverse ends two fastening surfaces 8a, 10a and 8b, 10b forming an angle between them. In a preferred embodiment, the two attachment surfaces are perpendicular to each other respectively. The load beam 2 is fixed by these attachment surfaces 8a, 8b, 10a, 10b to the body 9 of the railway vehicle. The body 9 of the vehicle is for example of aluminum material. The attachment between the load beam 2 of cast iron and the body 9 is preferably made by rivets or any other technically possible fastening means. However, the fixing is not performed by welding due to the heterogeneity of the assembled materials.

Selon la direction d'élévation, la traverse de charge 2 s'étend entre une face supérieure 12 et une face inférieure 14, les faces contenant une direction longitudinale et une direction transversale, la face supérieure 12 s'étendant au-dessus de la face inférieure 14.According to the elevation direction, the load crossbar 2 extends between an upper face 12 and a lower face 14, the faces containing a longitudinal direction and a transverse direction, the upper face 12 extending above the face. lower 14.

La traverse de charge 2 comprend au moins une concavité 16a, 16b, qui s'étend à partir de la face supérieure 12 en direction de la face inférieure 14. La concavité 16a, 16b permet de réduire la quantité de matériau de la fonte, ce qui rend la traverse de charge 2 plus légère, en gardant une résistance mécanique satisfaisante.The load crossbar 2 comprises at least one concavity 16a, 16b, which extends from the upper face 12 towards the lower face 14. The concavity 16a, 16b reduces the amount of material of the cast iron, which makes the load crossbar 2 lighter, keeping satisfactory mechanical strength.

La concavité 16a, 16b comprend une surface entre la face supérieure 12 et la face inférieure 14 qui forme le fond 17a, 17b de la concavité.
