Description

La présente invention concerne une structure de caisse de voiture de véhicule, notamment ferroviaire.The present invention relates to a vehicle car body structure, in particular railway.

Dans des structures de caisse de véhicule connues, il est connu d'utiliser une pièce structurelle dite « en col de cygne » faisant la liaison entre un passage d'une porte d'une voiture du véhicule et un espace de réception d'un bogie du véhicule. Les documents FR 3 024 117 A1 et JP 2018 176796 A décrivent des structures de caisse selon l'art antérieur.In known vehicle body structures, it is known to use a so-called “swan neck” structural part making the connection between a passage of a door of a car of the vehicle and a space for receiving a bogie of the vehicle. The documents FR 3 024 117 A1 And JP 2018 176796 A describe body structures according to the prior art.

L'appellation « col de cygne » provient de la forme de la pièce qui présente une partie sensiblement verticale et une partie inclinée par rapport à la partie verticale, et présentant une découpe arrondie au voisinage d'un bogie du véhicule, et une découpe sensiblement rectangulaire à bords arrondis au voisinage d'une porte du véhicule.The name "swan neck" comes from the shape of the part which has a substantially vertical part and a part inclined relative to the vertical part, and having a rounded cutout in the vicinity of a bogie of the vehicle, and a cutout substantially rectangular with rounded edges near a vehicle door.

Du fait de sa position, cette pièce subit des contraintes élevées et doit donc être conçue pour résister à ces contraintes.Due to its position, this part undergoes high stresses and must therefore be designed to withstand these stresses.

La forme particulière et la résistance aux contraintes de la pièce la rendent particulièrement complexe à réaliser, engendrant en outre un coût élevé.The particular shape and resistance to stress of the part make it particularly complex to produce, also generating a high cost.

Il existe donc un besoin pour une structure de caisse de véhicule plus simple à réaliser, tout en étant capable de résister à des contraintes importantes.There is therefore a need for a vehicle body structure that is simpler to produce, while still being capable of withstanding significant stresses.

A cet effet, la présente invention a pour objet une structure de caisse de voiture de véhicule, notamment ferroviaire, comprenant au moins deux pièces structurelles agencées transversalement de part et d'autre de la structure de caisse, dans laquelle chaque pièce structurelle présente une partie sensiblement verticale et une partie inclinée par rapport à la partie verticale, et comprend au moins deux profilés assemblés et réalisés en aluminium ou en matériau composite, la structure de caisse comprenant une poutre de jonction transversale fixée à chacune des deux pièces structurelles, la poutre de jonction transversale étant réalisée en acier ou en matériau composite, chaque pièce structurelle comprenant trois profilés assemblés, le premier profilé formant une partie supérieure de la pièce structurelle, et présente une forme sensiblement rectangulaire, le deuxième profilé formant une partie inférieure de la pièce structurelle, et comprend trois portions, comportant une première portion supérieure, une deuxième portion intermédiaire et une troisième portion inférieure, la première portion supérieure s'étendant dans le même plan que le premier profilé, la deuxième portion intermédiaire s'étendant entre la première portion et la troisième portion, la deuxième portion intermédiaire formant avantageusement un angle obtus avec la première portion, la troisième portion inférieure s'étendant depuis la deuxième portion intermédiaire et formant avantageusement un angle obtus avec la deuxième portion intermédiaire, de sorte que les trois portions, forment sensiblement un U évasé, et le troisième profilé s'étendant entre le premier profilé et le deuxième profilé.For this purpose, the present invention relates to a vehicle car body structure, in particular a railway body, comprising at least two structural parts arranged transversely on either side of the body structure, in which each structural part has a part substantially vertical and a part inclined relative to the vertical part, and comprises at least two profiles assembled and made of aluminum or composite material, the body structure comprising a transverse junction beam fixed to each of the two structural parts, the beam of transverse junction being made of steel or composite material, each structural part comprising three assembled profiles, the first profile forming an upper part of the structural part, and has a substantially rectangular shape, the second profile forming a lower part of the structural part, and comprises three portions, comprising a first upper portion, a second intermediate portion and a third lower portion, the first upper portion extending in the same plane as the first profile, the second intermediate portion extending between the first portion and the third portion, the second intermediate portion advantageously forming an obtuse angle with the first portion, the third lower portion extending from the second intermediate portion and advantageously forming an obtuse angle with the second intermediate portion, so that the three portions form substantially a flared U, and the third profile extending between the first profile and the second profile.

Grâce à la réalisation des pièces structurelles à l'aide d'au moins deux profilés en aluminium et d'une poutre de jonction en acier, les pièces structurelles et la poutre de jonction sont simples à produire, et l'ensemble est renforcé de telle sorte que la structure de caisse est résistante aux contraintes élevées.Thanks to the production of the structural parts using at least two aluminum profiles and a steel junction beam, the structural parts and the junction beam are simple to produce, and the whole is reinforced such so that the body structure is resistant to high stresses.

Dans la suite de la description, les termes « longitudinal », « transversal », « avant », « arrière », « gauche » et « droite » s'entendent par rapport au sens normal de circulation d'un véhicule.In the remainder of the description, the terms “longitudinal”, “transverse”, “front”, “rear”, “left” and “right” are understood in relation to the normal direction of movement of a vehicle.

Les termes « intérieur » et « extérieur » s'entendent par rapport au sens normal de l'intérieur de la voiture 10 et de l'extérieur de la voiture 10.The terms “interior” and “exterior” are understood in relation to the normal meaning of the interior of car 10 and the exterior of car 10.

Le véhicule est par exemple un véhicule ferroviaire.The vehicle is for example a railway vehicle.

En variante, le véhicule est un autobus.Alternatively, the vehicle is a bus.

La voiture 10 comprend une caisse 12.Car 10 includes a body 12.

La caisse 12 comprend un châssis 13.The body 12 includes a chassis 13.

La voiture 10 comprend au moins une porte 14 destinée à la montée ou la descente de voyageurs ou de personnel à bord de la voiture 10.The car 10 includes at least one door 14 intended for boarding or disembarking passengers or personnel on board the car 10.

La caisse 12 comprend une structure de caisse 18.The body 12 includes a body structure 18.

La structure de caisse 18 comprend notamment deux pièces structurelles 20, 21 agencées transversalement de part et d'autre de la structure de caisse et une poutre de jonction transversale 22 fixée à chacune des deux pièces structurelles 20, 21 comme cela est visible sur la figure 3.The body structure 18 comprises in particular two structural parts 20, 21 arranged transversely on either side of the body structure and a transverse junction beam 22 fixed to each of the two structural parts 20, 21 as is visible on the Figure 3 .

Chaque pièce structurelle 20, 21 dont une est représentée sur la figure 2 présente une partie sensiblement verticale et une partie inclinée par rapport à la partie verticale et comprend au moins deux profilés 24, 26, 28 assemblés comme cela sera décrit plus en détail ci-après.Each structural part 20, 21, one of which is represented on the figure 2 has a substantially vertical part and a part inclined relative to the vertical part and comprises at least two profiles 24, 26, 28 assembled as will be described in more detail below.

Chaque pièce structurelle 20, 21 est par exemple destinée à être placée entre un bogie 16 et une porte 12 de voiture de véhicule ferroviaire.Each structural part 20, 21 is for example intended to be placed between a bogie 16 and a door 12 of a railway vehicle car.

Les profilés 24, 26, 28 sont réalisés en aluminium ou en matériau composite. De préférence, les profilés 24, 26, 28 sont réalisés en aluminium.The profiles 24, 26, 28 are made of aluminum or composite material. Preferably, the profiles 24, 26, 28 are made of aluminum.

La pièce structurelle 20, 21 est donc légère et n'alourdit pas la voiture 10.The structural part 20, 21 is therefore light and does not weigh down the car 10.

Les profilés 24, 26, 28 sont par exemple assemblés les uns aux autres par soudage.The profiles 24, 26, 28 are for example assembled together by welding.

En particulier, chaque pièce structurelle 20, 21 comprend trois profilés 24, 26, 28 assemblés.In particular, each structural part 20, 21 comprises three assembled profiles 24, 26, 28.

Parmi les trois profilés 24, 26, 28, un premier profilé 24 forme une partie supérieure de la pièce structurelle 20, 21.Among the three profiles 24, 26, 28, a first profile 24 forms an upper part of the structural part 20, 21.

Le premier profilé 24 présente par exemple une forme sensiblement rectangulaire dont les deux grands côtés s'étendent sensiblement suivant la direction longitudinale L définie par rapport à un sens normal de circulation d'un véhicule.The first profile 24 has for example a substantially rectangular shape whose two long sides extend substantially in the longitudinal direction L defined in relation to a normal direction of movement of a vehicle.

Le premier profilé 24, et en particulier les deux grands côtés du premier profilé 24, s'étend entre un bord d'extrémité avant 30 et un bord d'extrémité arrière 32.The first profile 24, and in particular the two long sides of the first profile 24, extends between a front end edge 30 and a rear end edge 32.

Un deuxième profilé 26 forme une partie inférieure de la pièce structurelle 20, 21.A second profile 26 forms a lower part of the structural part 20, 21.

Le deuxième profilé 26 comprend par exemple trois portions 34, 36, 38 comportant une première portion supérieure 34, une deuxième portion intermédiaire 36 et une troisième portion inférieure 38.The second profile 26 comprises for example three portions 34, 36, 38 comprising a first upper portion 34, a second intermediate portion 36 and a third lower portion 38.

La première portion supérieure 34 s'étend avantageusement dans le même plan que le premier profilé 24.The first upper portion 34 advantageously extends in the same plane as the first profile 24.

La deuxième portion intermédiaire 36 s'étend avantageusement entre la première portion 34 et la troisième portion 38.The second intermediate portion 36 advantageously extends between the first portion 34 and the third portion 38.

La deuxième portion intermédiaire 36 forme avantageusement un angle obtus avec la première portion 34.The second intermediate portion 36 advantageously forms an obtuse angle with the first portion 34.

La troisième portion inférieure 38 s'étend depuis la deuxième portion intermédiaire 36.The third lower portion 38 extends from the second intermediate portion 36.

La troisième portion inférieure 38 forme avantageusement un angle obtus avec la deuxième portion intermédiaire 36 de sorte que les trois portions 34, 36, 38 forment sensiblement un U évasé.The third lower portion 38 advantageously forms an obtuse angle with the second intermediate portion 36 so that the three portions 34, 36, 38 substantially form a flared U.

Un troisième profilé 28 dit profilé de liaison s'étend entre le premier profilé 24 et le deuxième profilé 26.A third profile 28 called connecting profile extends between the first profile 24 and the second profile 26.

Le profilé de liaison 28 s'étend dans le même plan que le premier profilé 24 et que la première portion supérieure 30 du deuxième profilé 26.The connecting profile 28 extends in the same plane as the first profile 24 and the first upper portion 30 of the second profile 26.

Le profilé de liaison 28 présente par exemple un bord avant 40 découpé suivant une forme de demi-parabole, et un bord arrière 42 droit.The connecting profile 28 has for example a front edge 40 cut in the shape of a half-parabola, and a straight rear edge 42.

Le sommet de la demi-parabole se situe en partie supérieure du troisième profilé 28.The top of the half-parabola is located in the upper part of the third profile 28.

La forme en demi-parabole permet notamment d'encadrer le bogie 16 se trouvant sous la pièce structurelle 20, 21 lorsque celle-ci est en place sur une voiture 10 de véhicule ferroviaire.The half-parabolic shape makes it possible in particular to frame the bogie 16 located under the structural part 20, 21 when the latter is in place on a car 10 of a railway vehicle.

Le bord arrière 42 s'étend dans le prolongement du bord d'extrémité arrière 32 du premier profilé 24.The rear edge 42 extends in the extension of the rear end edge 32 of the first profile 24.

Le deuxième profilé 26 s'étend entre un bord d'extrémité avant 44 et un bord d'extrémité arrière 46.The second profile 26 extends between a front end edge 44 and a rear end edge 46.

Le bord d'extrémité avant 44 du deuxième profilé 26 est droit et s'étend dans le prolongement du bord d'extrémité avant 40 du profilé de liaison 28.The front end edge 44 of the second profile 26 is straight and extends in the extension of the front end edge 40 of the connecting profile 28.

Le bord d'extrémité arrière 46 du deuxième profilé 26 s'étend avantageusement d'abord dans le prolongement du bord d'extrémité arrière 42 du profilé de liaison 28 puis forme un angle de façon à ce que le bord d'extrémité arrière 46 du deuxième profilé 26 délimite une partie d'un passage de la porte 14.The rear end edge 46 of the second profile 26 advantageously extends first in the extension of the rear end edge 42 of the connecting profile 28 then forms an angle so that the rear end edge 46 of the second profile 26 delimits part of a passage of the door 14.

Par exemple, l'angle formé est sensiblement droit et présente des bords arrondis.For example, the angle formed is substantially straight and has rounded edges.

Les deux pièces structurelles 20, 21 sont symétriques par rapport à un plan.The two structural parts 20, 21 are symmetrical with respect to a plane.

En particulier, les deux pièces structurelles 20, 21 sont symétriques par rapport à un plan longitudinal médian P, ledit plan P séparant la voiture 10 en une moitié gauche et une moitié droite.In particular, the two structural parts 20, 21 are symmetrical with respect to a median longitudinal plane P, said plane P separating the car 10 into a left half and a right half.

Les deux pièces structurelles 20, 21 sont jointes entre elles par une poutre de jonction 22.The two structural parts 20, 21 are joined together by a junction beam 22.

La poutre de jonction transversale 22, visible sur la Figure 3, est réalisée en acier ou en matériau composite. De préférence, la poutre de jonction transversale 22 est réalisée en acier.The transverse junction beam 22, visible on the Figure 3 , is made of steel or composite material. Preferably, the transverse junction beam 22 is made of steel.

La poutre de jonction transversale 22 contribue ainsi à renforcer les deux pièces structurelles 20, 21 qui sont réalisées en aluminium.The transverse junction beam 22 thus contributes to reinforcing the two structural parts 20, 21 which are made of aluminum.

La poutre de jonction transversale 22 est disposée transversalement entre les deux pièces structurelles 20, 21 et s'étend entre deux extrémités 50, 52.The transverse junction beam 22 is arranged transversely between the two structural parts 20, 21 and extends between two ends 50, 52.

Chaque extrémité 50, 52 de la poutre de jonction transversale 22 prend appui sur deux profilés 26, 28 adjacents d'une pièce structurelle 20, 21.Each end 50, 52 of the transverse junction beam 22 is supported on two adjacent profiles 26, 28 of a structural part 20, 21.

En particulier, chaque extrémité 50, 52 de la poutre de jonction transversale 22 prend appui sur le deuxième profilé inférieur 26 et sur le profilé de liaison 28.In particular, each end 50, 52 of the transverse junction beam 22 bears on the second lower profile 26 and on the connecting profile 28.

Avantageusement, chaque extrémité 50, 52 de la poutre de jonction transversale 22 a une forme complémentaire de la forme des deux profilés 26, 28 sur lesquels elle prend appui.Advantageously, each end 50, 52 of the transverse junction beam 22 has a shape complementary to the shape of the two profiles 26, 28 on which it rests.

Cela permet d'obtenir un plaquage entre les profilés et la poutre de jonction transversale 22 en supprimant le jeu entre ces pièces.This makes it possible to obtain a connection between the profiles and the transverse junction beam 22 by eliminating the play between these parts.

Avantageusement, la poutre de jonction transversale 22 est fixée à chaque pièce structurelle 20, 21 par rivetage.Advantageously, the transverse junction beam 22 is fixed to each structural part 20, 21 by riveting.

La poutre de jonction transversale 22 est par exemple fabriquée à l'aide d'un gabarit d'assemblage.The transverse junction beam 22 is for example manufactured using an assembly template.

Les poutres de jonction 22 produites à partir d'un même gabarit présenteront donc des dimensions identiques, facilitant le respect des normes de largeur de caisse.The junction beams 22 produced from the same template will therefore have identical dimensions, facilitating compliance with body width standards.

Monter les pièces structurelles 20, 21 en appui sur la poutre de jonction transversale 22 permet d'avoir une largeur de caisse conforme au plan.Mounting the structural parts 20, 21 in support of the transverse junction beam 22 provides a body width conforming to the plan.

La structure de caisse 18 permet ainsi d'alléger la caisse 12 en proposant des pièces structurelles 20, 21 en aluminium, tout en garantissant une rigidité optimale à l'aide de la poutre de jonction transversale 22.The body structure 18 thus makes it possible to lighten the body 12 by offering structural parts 20, 21 in aluminum, while guaranteeing optimal rigidity using the transverse junction beam 22.

Un exemple de procédé d'assemblage de la structure de caisse 18 sur une voiture 10 de véhicule va maintenant être décrit.An example of a method of assembling the body structure 18 on a vehicle car 10 will now be described.

Les pièces structurelles 20, 21 sont placées en regard l'une de l'autre de façon symétrique par rapport au plan longitudinal médian P, ledit plan P séparant la voiture 10 en une moitié gauche et une moitié droite.The structural parts 20, 21 are placed facing each other symmetrically with respect to the median longitudinal plane P, said plane P separating the car 10 into a left half and a right half.

La poutre de jonction transversale 22 est assemblée aux pièces structurelles 20, 21 transversalement au plan P, de préférence par rivetage.The transverse junction beam 22 is assembled to the structural parts 20, 21 transversely to the plane P, preferably by riveting.

Avantageusement, le châssis 13 comporte une traverse basse transversale 60.Advantageously, the chassis 13 comprises a low transverse crosspiece 60.

La traverse basse transversale 60 est assemblée par exemple en même temps que la poutre de jonction transversale 22.The lower transverse crosspiece 60 is assembled for example at the same time as the transverse junction beam 22.

Les autres pièces de la caisse 12 sont ensuite assemblées.The other parts of box 12 are then assembled.
