Description

La présente invention concerne une caisse pour véhicule, tel qu'un véhicule ferroviaire.The present invention relates to a body for a vehicle, such as a railway vehicle.

L'invention concerne également un véhicule, tel qu'un véhicule ferroviaire, comprenant une telle caisse.The invention also relates to a vehicle, such as a railway vehicle, comprising such a body.

L'invention s'applique au domaine des transports, en particulier des transports ferroviaires.The invention applies to the field of transport, in particular rail transport.

Les véhicules, tels que des véhicules ferroviaires, comportent généralement une caisse permettant de transporter, par exemple, des passagers. Une telle caisse est souvent constituée d'une paroi extérieure en contact direct avec l'atmosphère extérieure, et d'une paroi intérieure délimitant le volume interne du véhicule. L'espace entre ces deux parois permet notamment de limiter la conduction thermique entre l'intérieur de la caisse et l'extérieur.Vehicles, such as railway vehicles, generally comprise a body making it possible to transport, for example, passengers. Such a box often consists of an outer wall in direct contact with the outside atmosphere, and an inner wall delimiting the internal volume of the vehicle. The space between these two walls makes it possible in particular to limit thermal conduction between the inside of the box and the outside.

En outre, une telle caisse comporte des éléments de support entre les deux parois, permettant de fixer la paroi intérieure sur la paroi extérieure l'une en face de l'autre. Ces éléments de support sont généralement réalisés en aluminium. Afin que les éléments de support maintiennent les parois de la façon la plus stable possible, il est nécessaire que les éléments de support aient une surface de contact importante avec les parois, et des moyens de fixation solides.In addition, such a box comprises support elements between the two walls, making it possible to fix the inner wall to the outer wall, one facing the other. These support elements are generally made of aluminum. In order for the support elements to hold the walls in the most stable way possible, it is necessary for the support elements to have a large contact surface with the walls, and solid fixing means.

Un problème existant est alors que la conduction thermique est importante au niveau des éléments de support, ce qui implique un isolement thermique de la caisse amoindri. En outre, plus la surface de contact entre les éléments de support et les parois est importante, plus la conduction thermique à travers l'élément de support, entre l'intérieur et l'extérieur de la caisse est importante.An existing problem is then that thermal conduction is high at the level of the support elements, which implies reduced thermal insulation of the body. In addition, the greater the contact surface between the support elements and the walls, the greater the thermal conduction through the support element, between the inside and the outside of the box.

Afin d'améliorer l'isolement de la caisse, il est possible d'ajouter une cale thermique en matériau isolant, entre une des parois et un élément de support, au niveau d'une surface de contact.In order to improve the insulation of the body, it is possible to add a thermal wedge of insulating material, between one of the walls and a support element, at the level of a contact surface.

Cependant, l'utilisation d'une cale thermique implique un coût de fabrication et un temps de montage plus important.However, the use of a thermal wedge involves a manufacturing cost and a greater assembly time.

L'un des buts de l'invention est de proposer une caisse pour véhicule permettant de limiter la conduction thermique entre l'intérieur et l'extérieur de la caisse, avec un coût de fabrication et un temps de montage réduits.One of the aims of the invention is to propose a body for a vehicle making it possible to limit thermal conduction between the inside and the outside of the body, with reduced manufacturing cost and assembly time.

A cet effet, l'invention a pour objet une caisse pour véhicule, tel qu'un véhicule ferroviaire, comprenant :

  • une paroi extérieure et une paroi intérieure, les parois extérieure et intérieure étant disposées l'une en face de l'autre,
  • au moins un élément de support en matériau thermiquement isolant entre la paroi intérieure et la paroi extérieure, l'au moins un élément de support comportant une première surface, de préférence plate, de contact avec la paroi extérieure,
  • des premiers moyens de fixation de l'au moins un élément de support avec la paroi extérieure, au niveau de la première surface, et
  • des deuxièmes moyens de fixation de l'au moins un élément de support avec la paroi intérieure.
To this end, the subject of the invention is a body for a vehicle, such as a railway vehicle, comprising:
  • an outer wall and an inner wall, the outer and inner walls being arranged opposite each other,
  • at least one support element made of thermally insulating material between the inner wall and the outer wall, the at least one support element comprising a first surface, preferably flat, of contact with the outer wall,
  • first means for fixing the at least one support element to the outer wall, at the level of the first surface, and
  • second means for fixing the at least one support element to the inner wall.

Une telle caisse permet de limiter la conduction thermique entre l'intérieur et l'extérieur de la caisse, en utilisant au moins un élément de support en matériau thermiquement isolant. En outre, le coût de fabrication d'un tel élément de support est réduit par rapport à une caisse avec des éléments de support en aluminium et une cale thermique. Enfin, l'élément de support présente une unique pièce, ce qui facilite le montage d'un tel élément de support, et réduit donc le temps de montage.Such a box makes it possible to limit thermal conduction between the inside and the outside of the box, by using at least one support element made of thermally insulating material. In addition, the manufacturing cost of such a support element is reduced compared to a crate with aluminum support elements and a thermal wedge. Finally, the support element has a single piece, which facilitates the assembly of such a support element, and therefore reduces the assembly time.

Suivant d'autres aspects avantageux, la caisse comporte l'une ou plusieurs des caractéristiques suivantes, selon toutes les combinaisons techniquement possibles :

  • au moins un élément de support est en matériau plastique, tel que le polyamide 6.6 ;
  • au moins un élément de support est en matériau plastique moulé ;
  • les premiers moyens de fixation comprennent au moins un rail en C et au moins une vis ;
  • la caisse comprend en outre une cale de fixation perpendiculaire à la paroi intérieure et solidaire de la paroi intérieure, les deuxièmes moyens de fixation étant apte à fixer l'au moins un élément de support à la cale de fixation ; et
  • au moins un élément de support comprend une deuxième surface de contact avec la cale de fixation, la deuxième surface étant perpendiculaire à la première surface, les deuxièmes moyens de fixation étant apte à fixer l'au moins un élément de support à la cale de fixation, au niveau de la deuxième surface.
According to other advantageous aspects, the cash register comprises one or more of the following characteristics, according to all the technically possible combinations:
  • at least one support element is made of plastic material, such as polyamide 6.6;
  • at least one support element is made of molded plastic material;
  • the first fixing means comprise at least one C-rail and at least one screw;
  • the body further comprises a fixing wedge perpendicular to the inner wall and integral with the inner wall, the second fixing means being capable of fixing the at least one support element to the fixing wedge; and
  • at least one support element comprises a second surface for contact with the fixing wedge, the second surface being perpendicular to the first surface, the second fixing means being capable of fixing the at least one support element to the fixing wedge , at the level of the second surface.

L'invention a également pour objet un véhicule, tel qu'un véhicule ferroviaire, comprenant une caisse telle que précédemment décrite.The invention also relates to a vehicle, such as a railway vehicle, comprising a body as previously described.

D'autres aspects et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple non limitatif, et faite en référence aux dessins annexés sur lesquels :

  • [Fig 1] la figure 1 est une représentation schématique d'une coupe transversale d'un plafond d'une caisse selon l'invention, comprenant notamment deux éléments de support, et
  • [Fig 2] la figure 2 est une représentation schématique d'un élément de support de la figure 1.
Other aspects and advantages of the invention will appear on reading the following description, given solely by way of non-limiting example, and made with reference to the appended drawings in which:
  • [ Fig 1 ] the figure 1 is a schematic representation of a cross section of a ceiling of a box according to the invention, comprising in particular two support elements, and
  • [ Fig 2 ] the figure 2 is a schematic representation of a support element of the figure 1 .

La figure 1 représente une coupe transversale d'une caisse 10 d'un véhicule. Plus précisément, elle représente une partie supérieure de la caisse 10, en particulier un plafond de la caisse 10.The figure 1 represents a cross section of a body 10 of a vehicle. More precisely, it represents an upper part of the body 10, in particular a ceiling of the body 10.

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

La caisse 10 comprend une paroi extérieure 20 et une paroi intérieure 22, les parois extérieure 20 et intérieure 22 étant disposées l'une en face de l'autre.The box 10 comprises an outer wall 20 and an inner wall 22, the outer 20 and inner 22 walls being arranged opposite each other.

Les parois extérieure 20 et intérieure 22 s'étendent sur toute la longueur de la caisse 10.The exterior 20 and interior 22 walls extend over the entire length of the box 10.

La caisse 10 comprend un plancher, un pavillon et des cloisons latérales. Le pavillon et les cloisons sont notamment formés des parois extérieure 20 et intérieure 22.The body 10 comprises a floor, a pavilion and side partitions. The pavilion and the partitions are in particular formed from the outer 20 and inner 22 walls.

Par exemple, au niveau du pavillon ou d'une cloison de la caisse 10, les parois extérieure 20 et intérieure 22 sont sensiblement parallèles.For example, at the level of the roof or a partition of the body 10, the outer 20 and inner 22 walls are substantially parallel.

La caisse 10 comprend, en outre, au moins un élément de support 26 entre la paroi extérieure 20 et la paroi intérieure 22, des premiers moyens de fixation 30 de l'au moins un élément de support 26 avec la paroi extérieure 20, et des deuxièmes moyens de fixation 32 de l'au moins un élément de support 26 avec la paroi intérieure 22.The box 10 further comprises at least one support element 26 between the outer wall 20 and the inner wall 22, first means 30 for fixing the at least one support element 26 to the outer wall 20, and second means 32 for fixing the at least one support element 26 with the inner wall 22.

A titre d'exemple, sur la figure 1 sont représentées deux éléments de support 26 de la caisse 10 au niveau du pavillon de la caisse 10.For example, on the figure 1 are shown two support elements 26 of the body 10 at the roof of the body 10.

En complément ou en variante, non représenté, la caisse 10 comprend des éléments de support 26 entre la paroi extérieure 20 et la paroi intérieure 22 au niveau d'une autre partie de la caisse 10, par exemple au niveau d'une cloison latérale de la caisse 10.In addition or as a variant, not shown, the box 10 comprises support elements 26 between the outer wall 20 and the inner wall 22 at the level of another part of the box 10, for example at the level of a side wall of the box 10.

Selon l'exemple de la figure 1, la caisse 10 comprend en outre, une cale de fixation 38 perpendiculaire à la paroi intérieure 22 et solidaire de la paroi intérieure 22.According to the example of figure 1 , the body 10 further comprises a fixing wedge 38 perpendicular to the inner wall 22 and secured to the inner wall 22.

La paroi extérieure 20 définit, par exemple, la surface extérieure de la caisse 10. Elle est en contact avec l'atmosphère extérieure.The outer wall 20 defines, for example, the outer surface of the box 10. It is in contact with the outside atmosphere.

La paroi intérieure 22 correspond, par exemple, à un habillage intérieur de la caisse 10. Elle délimite le volume interne de la caisse 10.The inner wall 22 corresponds, for example, to an interior lining of the box 10. It delimits the internal volume of the box 10.

Une zone d'isolation est située entre les parois extérieure 20 et intérieure 22. Elle comprend, par exemple un matériau d'isolation thermique.An insulation zone is located between the outer 20 and inner 22 walls. It comprises, for example, a thermal insulation material.

La figure 2 représente un élément de support 26, tel que ceux de la figure 1.The figure 2 represents a support element 26, such as those of the figure 1 .

L'élément de support 26 comporte une première surface 40 plate de contact avec la paroi extérieure 20.The support element 26 has a first flat surface 40 in contact with the outer wall 20.

L'élément de support 26 est en matériau thermiquement isolant.The support element 26 is made of thermally insulating material.

Selon l'exemple de la figure 2, l'élément de support 26 comprend, en outre une deuxième surface plate 42 de contact avec la cale de fixation 38.According to the example of figure 2 , the support element 26 further comprises a second flat surface 42 for contact with the fixing wedge 38.

Selon l'exemple de la figure 2, la deuxième surface 42 est perpendiculaire à la première surface 40.According to the example of figure 2 , the second surface 42 is perpendicular to the first surface 40.

La première surface 40 est adaptée pour être placée en contact de la paroi extérieure 20, la première surface 40 étant placée directement contre la paroi extérieure 20. La deuxième surface 42 est adaptée pour être placée en contact de la cale de fixation 38, la deuxième surface 42 étant placée directement contre la cale de fixation 38.The first surface 40 is adapted to be placed in contact with the outer wall 20, the first surface 40 being placed directly against the outer wall 20. The second surface 42 is adapted to be placed in contact with the fixing wedge 38, the second surface 42 being placed directly against the fixing block 38.

Selon l'exemple de la figure 2, la première surface 40 et respectivement, la deuxième surface 42 comprennent au moins un premier orifice de fixation 46 adapté pour accueillir les premiers moyens de fixation 30, et respectivement, au moins un deuxième orifice de fixation 48 adapté pour accueillir les deuxièmes moyens de fixation 32.According to the example of figure 2 , the first surface 40 and respectively, the second surface 42 comprise at least one first attachment hole 46 adapted to receive the first attachment means 30, and respectively, at least one second attachment hole 48 adapted to accommodate the second attachment means 32.

Par exemple, l'élément de support 26 est en matériau plastique, tel que le polyamide 6.6, aussi appelé PA6.6. En variante, l'élément de support 26 est fait en un autre matériau thermiquement isolant tel qu'un matériau composite ou du liège.For example, the support element 26 is made of plastic material, such as polyamide 6.6, also called PA6.6. Alternatively, the support element 26 is made of another thermally insulating material such as a composite material or cork.

De préférence, l'élément de support 26 est en matériau plastique moulé.Preferably, the support element 26 is made of molded plastic material.

Les premiers moyens de fixation 30 sont aptes à fixer l'au moins un élément de support 26 à la paroi extérieure 20, au niveau de sa première surface 40, plus particulièrement au niveau du ou des premiers orifices de fixation 46 de sa première surface 40.The first fixing means 30 are capable of fixing the at least one support element 26 to the outer wall 20, at the level of its first surface 40, more particularly at the level of the first fixing orifice(s) 46 of its first surface 40 .

Selon l'exemple de la figure 1, les premiers moyens de fixation 30 comprennent au moins un rail en C 50 et au moins une vis 52. Par exemple, les premiers moyens de fixation 30 comprennent, pour chaque orifice de fixation 46, un rail en C 50 et une vis 52.According to the example of figure 1 , the first fixing means 30 comprise at least one C-shaped rail 50 and at least one screw 52. For example, the first fixing means 30 comprise, for each fixing hole 46, a C-shaped rail 50 and a screw 52.

Chaque rail en C 50 est positionné en face d'un orifice de fixation 46, et chaque vis 52 étant propre à s'insérer à l'intérieur d'un orifice de fixation 46 et d'un rail en C 50.Each C-rail 50 is positioned opposite a fixing hole 46, and each screw 52 being capable of being inserted inside a fixing hole 46 and a C-shaped rail 50.

Les deuxièmes moyens de fixation 32 sont aptes à fixer l'au moins un élément de support 26 à la cale de fixation 38, au niveau de sa deuxième surface 42, plus particulièrement au niveau du ou des deuxièmes orifices de fixation 48 de sa deuxième surface 42.The second fixing means 32 are suitable for fixing the at least one support element 26 to the fixing block 38, at the level of its second surface 42, more particularly at the level of the second fixing hole(s) 48 of its second surface. 42.

La cale de fixation 38 est, par exemple, maintenue solidaire à la paroi intérieure 22, via d'autres moyens de fixation. Alternativement, la cale de fixation 38 et la paroi intérieure 38 sont soudées l'une à l'autre.The fixing wedge 38 is, for example, held integral with the inner wall 22, via other fixing means. Alternatively, the fixing wedge 38 and the inner wall 38 are welded together.

En variante non représentée, la caisse 10 ne comprend pas de cale de fixation 38.In a variant not shown, the body 10 does not include a fixing wedge 38.

Selon cette variante, l'au moins un élément de support 26 comprend une deuxième surface plate de contact directement avec la paroi intérieure 22. La première surface 40 et la deuxième surface se font alors face l'une par rapport à l'autre.According to this variant, the at least one support element 26 comprises a second flat surface in direct contact with the inner wall 22. The first surface 40 and the second surface then face each other.

Par exemple, selon cette variante, la première surface 40 et la deuxième surface sont sensiblement parallèles.For example, according to this variant, the first surface 40 and the second surface are substantially parallel.

Selon cette variante, la deuxième surface est adaptée pour être placée en contact de la paroi intérieure 22, la deuxième surface étant placée directement contre la paroi intérieure 22. Les deuxièmes moyens de fixation 32 sont alors aptes à fixer l'au moins un élément de support 26 à la paroi intérieure 22, au niveau de sa deuxième surface, plus particulièrement au niveau d'un ou de deuxièmes orifices de fixation de sa deuxième surface.According to this variant, the second surface is adapted to be placed in contact with the inner wall 22, the second surface being placed directly against the inner wall 22. The second fixing means 32 are then able to fix the at least one element of support 26 to the inner wall 22, at its second surface, more particularly at one or two second fixing holes of its second surface.

On comprend alors que l'élément de support 26 permet de fixer les parois extérieure 20 et intérieure 22 l'une en face de l'autre, en limitant la conduction thermique entre les parois extérieure 20 et intérieure 22, grâce à l'utilisation d'un matériau thermiquement isolant.It is then understood that the support element 26 makes it possible to fix the outer 20 and inner 22 walls opposite each other, by limiting the thermal conduction between the outer 20 and inner 22 walls, thanks to the use of a thermally insulating material.

En outre, les première et deuxième surfaces 40 et 42 permettent un appui solide respectivement des parois intérieures et extérieures 20 et 22 à l'au moins un élément de support 26, et donc une fixation robuste.In addition, the first and second surfaces 40 and 42 allow a solid support respectively of the inner and outer walls 20 and 22 to the at least one support element 26, and therefore a robust attachment.

De plus, l'utilisation du matériau plastique, tel que le PA6.6, donne aux éléments de support 26 une résistance importante. Les éléments de support 26 faits avec un tel matériau présentent en outre l'intérêt d'être plus légers que des éléments de support classiques en aluminium.In addition, the use of the plastic material, such as PA6.6, gives the support elements 26 a high resistance. The support elements 26 made with such a material also have the advantage of being lighter than conventional aluminum support elements.

Enfin, de tels éléments de support 26 permettent de se passer de l'utilisation d'une cale thermique, et permet donc d'avoir un coût de fabrication et un temps de montage réduits.Finally, such support elements 26 make it possible to dispense with the use of a thermal wedge, and therefore makes it possible to have a reduced manufacturing cost and assembly time.
