Description
La présente invention a pour objet un soufflet d'intercirculation pour matériel roulant, destiné par exemple à assurer la liaison entre deux voitures d'un ensemble mobile tel qu'un train, un tramway, un autobus, ou tout autre véhicule ferroviaire ou routier.The subject of the present invention is a bellows for rolling stock, intended by example to ensure the connection between two cars of a mobile assembly such as a train, a tram, a bus, or any other rail or road vehicle.
On sait que les voitures ferroviaires comportent à une extrémité de la caisse proprement dite un soufflet en accordéon destiné à relier les voitures entre elles pour assurer la protection vis-à-vis des intempéries, des passagers qui circulent entre les voitures, voir DE 3612425 A1.We know that rail cars have at one end of the body itself an accordion bellows intended to connect the cars between them to ensure protection from bad weather, passengers traveling between cars, see DE 3612425 A1.
Certains dispositifs connus font appel à une configuration rivetée réalisée en cuir avec comme renforts des profilés d'aluminium, tandis que d'autres sont réalisés en confection sur la base d'un tissu enduit sur ses deux faces de chlorure de polyvinyle (PVC), ou de caoutchouc, puis découpé, assemblé par collage et couture et enfin renforcé sur le contour extérieur des ondes par un profilé d'aluminium cintré et serti.Some known devices use a riveted configuration made of leather with like reinforcements of aluminum profiles, while others are made on the basis of a coated fabric on both sides of polyvinyl chloride (PVC), or rubber, then cut, assembled by gluing and sewing and finally reinforced on the outer contour of the waves by a bent and crimped aluminum profile.
L'exploitation de tels dispositifs n'est pas à l'abri de fuites dues aux coutures et reste limitée quant aux capacités de déformation du fait de l'orientation du support textile, ce qui a pour effet de conduire à des soufflets comportant un grand nombre d'ondes.The operation of such devices is not to protected from leaks due to seams and remains limited as to to the deformation capacities due to the orientation of the textile support, which has the effect of bellows with a large number of waves.
Le problème existe donc de fournir un soufflet de liaison à l'encontre des intempéries, notamment pour une voiture ferroviaire, assurant l'étanchéité et permettant d'absorber les débattements entre les voitures tout en conservant une géométrie développable pour garantir une bonne durée de vie.The problem therefore exists of providing a bellows of connection against bad weather, in particular for a railway car, ensuring watertightness and to absorb the travel between cars while maintaining a developable geometry for guarantee a good service life.
Un but général de la présente invention est d'apporter une solution avantageuse à ce problème.A general object of the present invention is to bring an advantageous solution to this problem.

C'est également un but de l'invention de fournir un soufflet où le matériau de base peut évoluer suivant la demande et les classements Feu/Fumée.It is also an object of the invention of provide a bellows where the base material can evolve according to demand and Fire / Smoke classifications.
C'est encore un but de l'invention de pouvoir raidir ou renforcer la raideur de certaines ondes, tout en ayant la possibilité de ne pas équiper le soufflet de renforts alors que l'aspect extérieur ne change pas.It is another object of the invention of power stiffen or strengthen the stiffness of certain waves, everything by having the possibility of not equipping the bellows with reinforcements while the external appearance does not change.
C'est aussi un but de l'invention de pouvoir s'adapter à la diversité des formes et des débattements.It is also a goal of the invention of power adapt to the diversity of shapes and deflections.
C'est également un but de l'invention de pouvoir utiliser des matériaux plus épais pour améliorer l'isolation phonique et/ou thermique.It is also an object of the invention of ability to use thicker materials to improve sound and / or thermal insulation.

having the features of
Cet assemblage par vulcanisation présente en outre l'avantage important d'éviter la présence de coutures qui d'une part nuisent à l'étanchéité et d'autre part constituent des zones de rétention des salissures.This vulcanization assembly presents in besides the important advantage of avoiding the presence of seams which affect waterproofing on the one hand and part constitute dirt retention zones.

Le soufflet d'interconnexion représenté à la
figure 1 est un soufflet 40 de liaison entre deux
voitures comportant un certain nombre de régions ondulées
ou ondes 2 vulcanisées en forme, sans couture, ni
collage.The interconnection bellows shown in
Figure 1 is a
Comme le montrent les figure 1a et 2, chaque
onde se présente sous la forme d'un cadre incliné 2 qui
présente en coupe une section sensiblement plane,
inclinée d'un angle α par rapport à la normale à l'axe
longitudinal XX' du soufflet. Le bord 21 du cadre 2 qui
est dirigé vers l'intérieur du soufflet 40 se prolonge
par une région plane 20 de contour fermé qui est
vulcanisée avec la région plane 20 de l'onde 2 qui lui
est adjacente. Le module représenté à la figure 1b
comporte à titre d'exemple six régions ondulées 2.As shown in Figures 1a and 2, each
wave is in the form of an
Le bord 22 du cadre 2 qui est dirigé vers
l'extérieur du soufflet 40 est prolongé par un raidisseur
extérieur 3 qui est commun à deux cadres 2 adjacents. Le
raidisseur 3 présente en coupe une section nettement
supérieure à celle des régions 2, alors que les cadres 2
constituent des ondes souples permettant d'assurer les
déplacements recherchés. De la sorte les raidisseurs 3 du
soufflet 40 conservent leur forme lors des déformations
des cadres 2. Ledit raidisseur extérieur 3 présente de
préférence des éléments de renfort 1 tels qu'un ou
plusieurs joncs en verre époxy qui sont logés dans le
raidisseur extérieur 3, et qui sont par exemple noyés
dans celui-ci notamment avec adhérisation sur le matériau
constituant le renfort extérieur 3, ou bien encore fixés
sur celui-ci, par exemple en étant disposés dans des
évidements ménagés à cet effet.The
Le raidisseur extérieur 3 forme un cadre
extérieur d'axe XX' de forme générale rectangulaire de
contour extérieur 35 et présentant des parties
sensiblement rectilignes 10, 12 et 14 reliées entre elles
par des régions de coin 11. Les renforts 1, sont de
préférence disposés uniquement dans les parties
sensiblement rectilignes 10, 12 et 14. The
Un renfort 1 est par exemple un jonc en verre
époxy de diamètre 4 à 6 mm, qui est fabriqué
classiquement à partir d'un jonc en verre tressé qui est
passé dans un bain de résine époxy, la résine étant
ensuite polymérisée.A
Le ou les renforts 1 selon l'invention permettent de s'affranchir des renforts d'onde en aluminium de l'Art Antérieur. De tels renforts en aluminium qui sont cintrés et sertis, sont de mise en oeuvre compliquée.The reinforcement (s) 1 according to the invention allow to overcome wave reinforcements by Aluminum of the Prior Art. Such reinforcements in aluminum which are bent and crimped, are complicated work.
Comme le montre la figure 3, le soufflet 40
est réalisé à partir de modules 50 mis bout à bout et
assemblés par exemple par des vis 6, au niveau de
raidisseurs extérieurs d'extrémité 30. Les cadres 2 qui
forment la partie centrale de l'onde, les régions planes
20 et les raidisseurs extérieurs 3 et 30 sont réalisés en
élastomère vulcanisé par exemple en caoutchouc, et plus
particulièrement en tissu caoutchouté vulcanisé, les
ondes 2 étant assemblées entre elles par vulcanisation,
cette vulcanisation assurant la cohésion mécanique et
l'étanchéité au niveau des cadres 2 et des raidisseurs
extérieurs 3.As shown in Figure 3, the
Les assemblages par contour ou collage de l'Art Antérieur sont ainsi avantageusement remplacés par la vulcanisation de la matière sur elle-même.Contour or bonding of Prior Art are thus advantageously replaced by the vulcanization of the material on itself.
Chaque module 50 peut présenter deux
raidisseurs d'extrémité 30 délimités longitudinalement
par des régions de contour fermé 36 permettant leur
assemblage par exemple par des vis 6. Ces régions 36
peuvent présenter des profils complémentaires 31, par
exemple en dents de scie, pour assurer une étanchéité
sans avoir un nombre de vis de fixation 6 très important
(figure 3). Les vis de fixation 6 peuvent être ainsi
écartées de par exemple 200 à 300 mm.Each
Les renforts d'onde 1 peuvent être combinés
pour former une partie très légère, présentant un module
de flexion évolutif suivant la caractérisation des joncs
et leur fonctionnement.
Le renfort d'ondes 1 peut être le support de
l'onde et remplacer avantageusement le tissu sur sa
surface pour créer une onde se comportant comme "un
ressort plat".The
La fixation d'extrémité peut être reprise sur
un raidisseur 32 aux dimensions plus importantes que le
raidisseur 30 et qui est adhérisé au cadre d'extrémité 2'
et percé en 38 pour la fixation sur la caisse de la
voiture (voir figure 1b).The end fixing can be resumed on
a
Dans une forme avantageuse, chaque extrémité peut être constituée d'un câble métallique fixé sur l'onde, à l'extérieur ou à l'intérieur de celle-ci pour assurer la fixation du soufflet sur un profilé prévu à cet effet.In an advantageous form, each end may consist of a metal cable fixed on the wave, outside or inside of it for secure the bellows on a profile provided for this effect.
Dans l'exemple préféré, le soufflet 40 dans
son ensemble est constitué de 2 ou 3, voire 4, modules 50
qui sont des éléments moulés, vulcanisés et qui sont
assemblés par ce système où le repère 30 constitue le
raidisseur en caoutchouc moulé équipé de ses renforts
verre-résine 5, l'ensemble constitué par les modules C et
D étant assemblé ici par l'intermédiaire de vis 6 (figure
3). La figure 1 représente un soufflet 40 constitué de
deux modules 50.In the preferred example, the
De manière avantageuse, la totalité du cadre 2
peut être réalisé sur la base d'une nappe 7 de joncs de
verre époxy pour assurer une grande raideur verticale au
cadre 2 tout en conservant ses possibilités de
déformation. Cette nappe de joncs comporte par exemple
des joncs de fils de verre époxy espacés d'un pas par
exemple de 5 à 10 mm et solidarisés entre eux par des
fils de trame pour former la nappe 7. Les régions de coin
11 peuvent également être pourvues d'une nappe 7.Advantageously, the
Comme représenté à la figure 4, la nappe 7 qui constitue le renfort est noyée dans le caoutchouc. As shown in Figure 4, the web 7 which constitutes the reinforcement is embedded in the rubber.
En outre, la présente invention s'applique également à conférer de la raideur aux joints d'étanchéité moulés ou extrudés.Furthermore, the present invention applies also to give stiffness to the joints sealing molded or extruded.
Le soufflet selon l'invention peut présenter à
une extrémité un joint d'étanchéité 55 moulé ou extrudé
qui est ensuite adhérisé (ou collé) au soufflet. Un mode
de réalisation préféré de ce joint est représenté à la
figure 5. Il présente une région de renfort 58 dans
laquelle sont de préférence noyés un ou plusieurs
éléments de renfort 8, par exemple un ou plusieurs joncs
en verre-résine, et une lèvre 9 destinée à assurer
l'étanchéité.The bellows according to the invention may have
one end a
