Description

Dispositif d'accouplement entre
deux conduits tubulaires
La présente invention se rapporte à un dispositif d'accouplement entre deux conduites de fluide tubulaires, ledit dispositif permettant un déplacement angulaire entre les deux conduites tout en conservant l'étanchéité.Coupling device between
two tubular conduits
The present invention relates to a coupling device between two tubular fluid conduits, said device allowing angular displacement between the two conduits while retaining the seal.

Le problème de la réalisation d'un tel mode d'accouplement se pose, par exemple, dans le cas d'une ligne d'échappement d'un moteur à combustion interne équipé d'un silencieux catalytique. The problem of producing such a coupling mode arises, for example, in the case of an exhaust line of an internal combustion engine equipped with a catalytic silencer.

Il existe actuellement des dispositifs d'accouplement souple : le soufflet slmpln et d autres techn5qiie' clont l'llno d'entre elles est représentée en figure 1. There are currently flexible coupling devices: the bellows slmpln and other techn5qiie 'clll illo of them is shown in Figure 1.

Sur cette figure 1, la référence 1 désigne le tube directement relié au collecteur d'échappement d'un moteur à combustion interne de véhicule automobile et la référence 2 désigne le tube, de même diamètre, qui est relié au silencieux. Le dispositif d'accouplement flexible 3 est, dans ce dispositif connu, composé essentiellement d'une première bride annulaire 4 soudée sur le pourtour du tube 1, d'une deuxième bride annulaire 5 soudée sur le pourtour du tube 2, ces deux brides étant reliées par une liaison à rotule 6 dont la partie mâle à portée sphérique 7 est constituée par un joint en fils d'acier inoxydable agglomérés et dont la partie femelle correspondante 8 est constituée par une protubérance tubulaire de la bride 5.La fixation souple des deux brides 4 et 5 l'une à l'autre est réalisée par des tirants 9, avec ressorts de répulsion 10, entre la bride 5 et une rondelle 13 serrée par l'écrou 14, qui d'une part coulissent sans jeu dans des perçages longitudinaux 11 du flasque 5, et d'autre part traversent des petites rotules 12 engagées dans des perçages 33 de la bride 4, vis-à-vis des perçages correspondants 11 dans la bride 5.  In this FIG. 1, the reference 1 designates the tube directly connected to the exhaust manifold of an internal combustion engine of a motor vehicle and the reference 2 designates the tube, of the same diameter, which is connected to the silencer. The flexible coupling device 3 is, in this known device, essentially composed of a first annular flange 4 welded on the periphery of the tube 1, a second annular flange 5 welded on the periphery of the tube 2, these two flanges being connected by a ball joint 6 whose male part with spherical bearing 7 is constituted by a joint made of agglomerated stainless steel wires and whose corresponding female part 8 is constituted by a tubular protuberance of the flange 5. The flexible fixing of the two flanges 4 and 5 to each other is produced by tie rods 9, with repulsion springs 10, between the flange 5 and a washer 13 tightened by the nut 14, which on the one hand slide without play in bores longitudinal 11 of the flange 5, and on the other hand pass through small ball joints 12 engaged in bores 33 of the flange 4, opposite the corresponding bores 11 in the flange 5.

Ce genre de dispositifs connu résiste convenablement aux températures élevées et permet une transmission des mouve ments longitudinaux. Il a néanmoins pour inconvénient de ne pas assurer une étanchéité suffisante, d'être complexe en raison de l'utilisation de rotules 12 en association avec les tirants9, et d'utiliser une rotule 6 qui n'est pas interchangeable indépendamment des conduites 1 et 2 qu'elle réunit. This type of known device withstands high temperatures well and allows transmission of longitudinal movements. However, it has the drawback of not ensuring a sufficient seal, of being complex due to the use of ball joints 12 in association with the tie rods 9, and of using a ball joint 6 which is not interchangeable independently of the pipes 1 and 2 that it brings together.

Le dispositif d'accouplement de l'invention ne présente pas les inconvénients des dispositifs connus jusqu'alors. The coupling device of the invention does not have the drawbacks of the devices known hitherto.

Il est du type comportant,d'une part, deux brides annulaires fixées chacune sur une extrémité des deux conduites à accoupler et solidarisées par un dispositif de tension élastique, ou analogue, autorisant un mouvement relatif des deux brides et,d'autre part, une rotule de liaison entre les deux conduites, et il est caractérisé en ce qu'il est composé d'une cartouche tubulaire destinée à être montée entre les deux brides comportant ladite rotule de liaison, et délimitée vers l'extérieur par un soufflet s'adaptant de manière étanche sur les deux extrémités, rabattues chacune en collerette de ladite cartouche tubulaire.It is of the type comprising, on the one hand, two annular flanges fixed each on one end of the two pipes to be coupled and secured by an elastic tensioning device, or the like, allowing a relative movement of the two flanges and, on the other hand, a ball joint between the two pipes, and it is characterized in that it is composed of a tubular cartridge intended to be mounted between the two flanges comprising said ball joint, and delimited towards the outside by a bellows s' fitting tightly on the two ends, each folded down as a collar of said tubular cartridge.

Avantageusement par ailleurs, ledit dispositif de tension élastique comporte plusieurs tirants associés chacun à un ressort coaxial qu'il vient comprimer contre une des deux brides, ledit tirant traversant les deux brides avec jeu. Advantageously also, said elastic tensioning device comprises several tie rods each associated with a coaxial spring which it comes to compress against one of the two flanges, said tie rod passing through the two flanges with play.

Préférentiellement alors, le centre de rotation de la rotule est situé dans le plan transversal d'appui de l'une des extrémités desdits ressorts sur la bride correspondante.Preferably then, the center of rotation of the ball joint is located in the transverse plane of support of one of the ends of said springs on the corresponding flange.

L'invention sera mieux comprise, et d'autres caractéristiques avantageuses apparaîtront, au cours de la description suivante d'un exemple de réalisation, en référence à la figure 2 annexée qui en est une vue latérale schématique avec demi-coupe passant par l'axe. The invention will be better understood, and other advantageous characteristics will appear, during the following description of an exemplary embodiment, with reference to the appended FIG. 2 which is a schematic side view thereof with half-section passing through it. axis.

Sur la figure 2, les éléments homologues à ceux de la figure 1 y ont été désignés par les mêmes chiffres de référence. Il s'agit en l'espèce des conduites cylindriques 1 et 2, des deux brides associées 4 et 5, et des tirants 9 avec les ressorts tendeurs 10 associés aux rondelles 13 et écrous 14. Dans ce cas toutefois, la bride 5 est une simple bride plane annulaire comme représenté. In FIG. 2, the elements homologous to those of FIG. 1 have been designated therein by the same reference numbers. These are cylindrical pipes 1 and 2, the two associated flanges 4 and 5, and tie rods 9 with the tension springs 10 associated with the washers 13 and nuts 14. In this case, however, the flange 5 is a simple flat annular flange as shown.

Conformément à l'invention, la liaison à rotule entre les deux extrémités en regard des conduites d'échappement 1 et 2 est réalisée de manière étanche par une cartouche interchangeable 15 pressée entre les brides 4 et 5 par l'intermédiaire de deux points d'étanchéité annulaires 16. In accordance with the invention, the ball joint connection between the two opposite ends of the exhaust pipes 1 and 2 is made in leaktight manner by an interchangeable cartridge 15 pressed between the flanges 4 and 5 by means of two points of ring seals 16.

Comme on le voit sur le dessin, la cartouche 15 enferme une rotule 17 à portée sphérique, dont le centre O est préférentiellement situé à l'intersection de l'axe longitudinal 18 et du plan d'appui 19 des ressorts 10 sur la bride 5. La partie femelle 20 de la rotule 17 est en acier, et sa partie mâle 21 est en matière pour joint métallique aggloméré, tel qu'en fil inoxydable. Préférentiellement, la rotule 17 est placée au milieu, dans le sens longitudinal de la cartouche 15. As can be seen in the drawing, the cartridge 15 encloses a ball joint 17 with a spherical bearing, the center O of which is preferably located at the intersection of the longitudinal axis 18 and the support plane 19 of the springs 10 on the flange 5 The female part 20 of the ball joint 17 is made of steel, and its male part 21 is made of material for agglomerated metal joint, such as stainless steel wire. Preferably, the ball joint 17 is placed in the middle, in the longitudinal direction of the cartridge 15.

La cartouche 15 a une allure générale tubulaire et comporte deux manchons ou coupelles 22, supportant la rotule 17 dont les extrémités 23 sont rabattues en collerette, un soufflet 24, soudé à ses deux extrémités sur ces collerettes 23, formant la partie extérieure visible de la cartouche. Deux cales annulaires 25 maintiennent la rotule 17 en position entre les deux coupelles 23. The cartridge 15 has a generally tubular appearance and comprises two sleeves or cups 22, supporting the ball joint 17 whose ends 23 are folded down as a flange, a bellows 24, welded at its two ends to these flanges 23, forming the visible external part of the cartridge. Two annular wedges 25 hold the ball joint 17 in position between the two cups 23.

Par ailleurs, selon une autre caractéristique avantageuse de l'invention, les tirants 9 traversent les deux brides 4 et 5 avec un jeu j qui autorise le débattement angulaire des deux conduites 1 et 2 sans qu'il soit nécessaire de faire usage de rotules supplémentaires comme c'était le cas pour le dispositif de la figure 1. Furthermore, according to another advantageous characteristic of the invention, the tie rods 9 pass through the two flanges 4 and 5 with a clearance j which allows the angular movement of the two pipes 1 and 2 without it being necessary to make use of additional ball joints as was the case for the device in Figure 1.

On remarquera finalement que le dispositif de l'invention est parfaitement étanche, qu'il a toutes les qualités pour résister aux gaz d'échappement, et qu'il est aisément interchangeable. Finally, it will be noted that the device of the invention is perfectly sealed, that it has all the qualities to resist exhaust gases, and that it is easily interchangeable.

L'invention n'est bien évidemment pas limitée à l'exem- ple de réalisation qui vient d'être décrit. La cartouche 17 pourrait comporter moins d'éléments constitutifs séparés, étant donné par exemple que les éléments 25, 22, 20 d'une part, et 25, 22, 21 d'autre part pourraient être chacun monolithiques. Les dispositifs tendeurs 9, 10 pourraient être remplacés par des dispositifs tendeurs d'un autre type par exemple, dans le cas où l'on effectuerait un montage inamovible, ils pourraient être consitués par des ressorts de traction ancrés à leurs deux extrémités sur les deux faces en regard des brides 4 et 5.  The invention is obviously not limited to the embodiment which has just been described. The cartridge 17 could comprise fewer separate constituent elements, given for example that the elements 25, 22, 20 on the one hand, and 25, 22, 21 on the other hand could each be monolithic. The tensioning devices 9, 10 could be replaced by tensioning devices of another type for example, in the case where an irremovable assembly is carried out, they could be constituted by tension springs anchored at their two ends on both opposite sides of flanges 4 and 5.
