Description

La présente invention concerne un bogie de véhicule ferroviaire du type comprenant :

  • au moins deux longerons s'étendant selon une direction longitudinale entre une première extrémité et une deuxième extrémité,
  • au moins une poutre transversale s'étendant selon une direction transversale sensiblement perpendiculaire à la direction longitudinale et reliant les deux longerons l'un à l'autre.
The present invention relates to a railway vehicle bogie of the type comprising:
  • at least two longitudinal members extending in a longitudinal direction between a first end and a second end,
  • at least one transverse beam extending in a transverse direction substantially perpendicular to the longitudinal direction and connecting the two longitudinal members to one another.

Il est connu, pour réaliser ce type de bogie, de fixer les différents éléments qui composent le châssis au moyen de soudures, par exemple en soudant les extrémités de la poutre transversale aux extrémités des longerons afin de rendre les pièces solidaires entre elles.It is known, to achieve this type of bogie, to fix the various elements that make up the frame by means of welds, for example by welding the ends of the transverse beam to the ends of the side members to make the parts integral with each other.

La structure de ce type de bogie, notamment l'accessibilité limitée de certaines zones du châssis, impose un soudage manuel ou semi-automatique des pièces. Ceci a pour effet de rendre la fabrication du châssis complexe et longue.The structure of this type of bogie, including the limited accessibility of certain areas of the chassis, requires a manual or semi-automatic welding of parts. This has the effect of making the manufacture of the chassis complex and long.

De plus, la qualité des soudures peut varier d'un châssis à un autre et d'une soudure à une autre sur un même châssis.In addition, the quality of the welds can vary from one frame to another and from one weld to another on the same frame.

L'un des buts de l'invention est de pallier ces inconvénients en proposant un bogie dont la structure du châssis permet l'utilisation d'équipements robotisés afin d'automatiser majoritairement la réalisation des soudures tout en rendant le châssis plus modulaire et en garantissant une qualité de soudure optimale.One of the aims of the invention is to overcome these drawbacks by proposing a bogie whose chassis structure allows the use of robotic equipment to automate the majority of the welding process while making the chassis more modular and ensuring an optimal welding quality.

A cet effet, l'invention concerne un bogie de véhicule ferroviaire du type précité dans lequel le châssis comprend au moins deux organes de maintien soudés respectivement à la première extrémité de chacun des longerons et en ce que la poutre transversale est fixée par boulonnage sur chacun des organes de maintien.For this purpose, the invention relates to a railway vehicle bogie of the aforementioned type in which the frame comprises at least two holding members welded respectively to the first end of each of the longitudinal members and in that the transverse beam is fixed by bolting on each holding members.

Ainsi, le soudage des organes de maintien sur les extrémités des longerons est une opération qui peut facilement être réalisée par des équipements de soudage robotisés. En effet, l'absence de poutre transversale dans l'environnement des zones de soudures facilite l'accès des équipements robotisés.Thus, the welding of the holding members on the ends of the spars is an operation that can easily be performed by robotic welding equipment. Indeed, the absence of transverse beam in the environment of the weld zones facilitates the access of robotic equipment.

Selon des modes de réalisation différents, le bogie comprend en outre une ou plusieurs des caractéristiques suivantes, prises isolément ou selon toutes les combinaisons techniquement possible :

  • l'organe de maintien enserre la première extrémité du longeron ;

  • l'organe de maintien est soudé à l'extrémité du longeron au moyen d'une première soudure bout à bout entre la partie supérieure de l'organe de maintien et la partie haute de l'extrémité du longeron et d'une deuxième soudure bout à bout entre la partie inférieure de l'organe de maintien et la partie basse du longeron ;
  • la projection de l'extrémité du longeron dans le plan longitudinal présente un profil continu, ledit profil présentant une pente variant continûment ;
  • l'organe de maintien est soudé à l'extrémité du longeron au moyen d'une soudure d'angle circulaire ;
  • le châssis comporte en outre au moins une traverse centrale, s'étendant dans la direction transversale, reliant les deux longerons l'un à l'autre dans une zone s'étendant entre la première extrémité et la deuxième extrémité des longerons, la traverse centrale comprenant une partie haute, une partie basse, deux flancs, la partie haute et la partie basse reliant les deux flancs, au moins un flanc étant formé d'une unique tôle découpée sensiblement plane et non pliée ;
  • le flanc de la traverse centrale est soudé à la partie basse de la traverse centrale au moyen d'une soudure rectiligne ;
  • le châssis comporte :
    • au moins une traverse centrale s'étendant dans la direction transversale, reliant les deux longerons l'un à l'autre dans une zone s'étendant entre la première extrémité et la deuxième extrémité des longerons, la traverse centrale comprenant une partie haute, une partie basse, deux flancs, la partie haute et la partie basse reliant les deux flancs, au moins l'une des parties haute et basse de la traverse centrale comportant une portion en saillie selon sensiblement la direction longitudinale,
    • une attache de bielle, par exemple destiné à fixer une bielle de réducteur, ladite attache étant soudée sur la portion en saillie d'au moins l'une des parties haute et basse de la traverse centrale.

  • the projection of the end of the spar in the longitudinal plane has a continuous profile, said profile having a continuously varying slope;
  • the holding member is welded to the end of the spar by means of a circular angle weld;
  • the chassis further comprises at least one central cross member, extending in the transverse direction, connecting the two longitudinal members to one another in an area extending between the first end and the second end of the longitudinal members, the central cross member comprising an upper part, a lower part, two sides, the upper part and the lower part connecting the two sides, at least one side being formed of a single cut sheet substantially flat and unfolded;
  • the side of the central web is welded to the lower part of the central web by means of a straight weld;
  • the chassis comprises:
    • at least one central cross-piece extending in the transverse direction, connecting the two longitudinal members to one another in an area extending between the first end and the second end of the longitudinal members, the central cross-member comprising a top part, a lower part, two sidewalls, the upper part and the lower part connecting the two sidewalls, at least one of the upper and lower parts of the central crosspiece having a projecting portion substantially in the longitudinal direction,

  • fixation de la poutre transversale par boulonnage sur chacun des organes de maintien.
The invention also relates to a method for manufacturing a railway vehicle bogie as described above. The manufacturing process comprises the following steps:
  • supply of at least two spars extending in a longitudinal direction, each spar having two flanks, an upper part and a lower part, the upper part and the lower part connecting the two flanks,

D'autres aspects et avantages de l'invention apparaîtront à la lecture de la description qui suit, donnée à titre d'exemple et faite en référence aux dessins annexés parmi lesquels :

  • la figure 1 est une représentation schématique d'un châssis d'un bogie selon l'invention ;
  • la figure 2 est une représentation schématique partiellement en éclaté d'une extrémité d'un longeron de la figure 1 ;
  • la figure 3 est une représentation schématique d'une variante d'un organe de maintien ; et
  • la figure 4 est une représentation d'une traverse centrale du bogie de la figure 1.
Other aspects and advantages of the invention will appear on reading the description which follows, given by way of example and with reference to the appended drawings among which:
  • the figure 1 is a schematic representation of a chassis of a bogie according to the invention;
  • the figure 2 is a schematic representation partially exploded from one end of a spar of the figure 1 ;
  • the figure 3 is a schematic representation of a variant of a holding member; and
  • the figure 4 is a representation of a central beam of the bogie of the figure 1 .

Dans la description qui suit, le terme « longitudinal » est défini par rapport à la direction selon laquelle circule le véhicule ferroviaire auquel appartient le bogie, c'est-à-dire la direction dans laquelle s'étendent les rails sur lesquels circule le véhicule.In the description that follows, the term "longitudinal" is defined with respect to the direction in which the railway vehicle to which the bogie belongs, that is to say the direction in which the rails on which the vehicle is traveling, runs. .

Le terme « transversal » est défini par rapport à une direction sensiblement perpendiculaire à la direction longitudinale, c'est-à-dire la direction selon laquelle les rails sont écartés l'un de l'autre.The term "transverse" is defined relative to a direction substantially perpendicular to the longitudinal direction, that is to say the direction in which the rails are spaced apart from each other.

Un châssis 1 d'un bogie pour véhicule ferroviaire est représenté sur la figure 1.A chassis 1 of a bogie for a railway vehicle is represented on the figure 1 .

Le châssis 1 comprend deux longerons 3 s'étendant chacun selon une direction longitudinale entre une première extrémité 5 et une deuxième extrémité 7 et deux poutres transversales 9A s'étendant selon une direction transversale et reliant les deux longerons 3 l'un à l'autre.The frame 1 comprises two longitudinal members 3 each extending in a longitudinal direction between a first end 5 and a second end 7 and two transverse beams 9A extending in a transverse direction and connecting the two side members 3 to each other .

En variante, le châssis 1 comprend plus de deux longerons 3 et/ou plus ou moins de poutres transversales 9A.Alternatively, the frame 1 comprises more than two longitudinal members 3 and / or more or less transverse beams 9A.

Chaque longeron 3 comprend deux flancs 11, une partie haute 13 et une partie basse 15. La partie haute 13 et la partie basse 15 relient les deux flancs 11 entre eux, de sorte que le longeron présente une section fermée sensiblement rectangulaire.Each spar 3 comprises two flanks 11, an upper part 13 and a lower part 15. The upper part 13 and the lower part 15 connect the two flanks 11 between them, so that the spar has a substantially rectangular closed section.

Typiquement, la projection de la première extrémité 5 et/ou de la deuxième extrémité 7 de chacun des longerons 3 dans un plan longitudinal a un profil continu et la pente dudit profil varie également continûment.Typically, the projection of the first end 5 and / or the second end 7 of each of the longitudinal members 3 in a longitudinal plane has a continuous profile and the slope of said profile also varies continuously.

Autrement dit, la projection de la première extrémité 5 et/ou de la deuxième extrémité 7 de chacun des longerons 3 dans un plan longitudinal a un profil dépourvu d'angles vifs.In other words, the projection of the first end 5 and / or the second end 7 of each of the longitudinal members 3 in a longitudinal plane has a profile devoid of sharp angles.

La projection de la première extrémité 5 et/ou de la deuxième extrémité 7 de chacun des longerons 3 dans un plan longitudinal a typiquement un profil correspondant à un arc géométrique de classe C1. Le profil est continu et la dérivée dudit profil est également continue.The projection of the first end 5 and / or the second end 7 of each of the longitudinal members 3 in a longitudinal plane typically has a profile corresponding to a class C1 geometric arc. The profile is continuous and the derivative of said profile is also continuous.

Par exemple, le profil est un demi-cercle.For example, the profile is a semicircle.

Les flancs 11 de chaque longeron 3 sont par exemple en tôle d'épaisseur comprise entre 6 mm et 16 mm. On entend par tôle une fine feuille de métal, par exemple de l'acier, obtenue par laminage.The flanks 11 of each spar 3 are for example sheet metal thickness between 6 mm and 16 mm. Sheet metal is a thin sheet of metal, for example steel, obtained by rolling.

La tôle formant les flancs 11 de chaque longeron 3 est non pliée et sensiblement plane. La tôle de chacun des flancs 11 est typiquement découpée dans une tôle de plus grande dimension.The sheet forming the flanks 11 of each spar 3 is unfolded and substantially flat. The sheet of each of the flanks 11 is typically cut into a sheet of larger size.

La partie haute 13 et la partie basse 15 de chacun des longerons 3 sont par exemple formées d'une pluralité de tôles fixées entre elles.The upper part 13 and the lower part 15 of each of the longitudinal members 3 are for example formed of a plurality of sheets fixed together.

En variante, la partie haute 13 et la partie basse 15 sont formées d'une unique tôle pliée, typiquement découpée dans une tôle de plus grande dimension.Alternatively, the upper part 13 and the lower part 15 are formed of a single folded sheet, typically cut into a sheet of larger size.

La partie haute 13 et la partie basse 15 sont par exemple formées d'une tôle similaire à celle utilisée pour la fabrication des flancs 11.The upper part 13 and the lower part 15 are for example formed of a sheet similar to that used for the manufacture of the flanks 11.

Au niveau de chaque extrémité 5, 7 de chacun des longerons 3, les deux flancs 11 s'étendent au-delà de la partie haute 13 et de la partie basse 15 selon la direction longitudinale.At each end 5, 7 of each of the longitudinal members 3, the two flanks 11 extend beyond the upper part 13 and the lower part 15 in the longitudinal direction.
