Description

2883063 1 Dispositif de liaison d'un tube et d'un élément de ligne d'échappement La présente invention se rapporte à un dispositif de liaison d'un tube et d'un élément de ligne d'échappement. Préférentiellement, mais de manière non exclusive, elle concerne une bride de liaison pour le raccordement de deux éléments du circuit de recyclage des gaz d'échappement d'un moteur diesel d'un véhicule automobile.  The present invention relates to a device for connecting a tube and an exhaust line element. Preferably, but not exclusively, it relates to a connecting flange for connecting two elements of the exhaust gas recirculation circuit of a diesel engine of a motor vehicle.

Un tel circuit est, principalement, composé d'une vanne de régulation des débits de gaz, d'un refroidisseur destiné à abaisser la température desdits gaz, et d'un ensemble de tubulures de liaison, permettant de renvoyer à l'admission du moteur une partie desdits gaz, afin que ceux-ci soient recyclés, de manière à diminuer l'émission de polluants.  Such a circuit is, mainly, composed of a gas flow control valve, a cooler for lowering the temperature of said gases, and a set of connecting pipes, for referring to the engine intake. a portion of said gases, so that they are recycled, so as to reduce the emission of pollutants.

En raison des contraintes fonctionnelles qui lui sont liées, d'une part, et, d'autre part, des contraintes dimensionnelles et d'encombrement de l'environnement dans lequel un tel circuit est placé, les liaisons entre les éléments composant ledit circuit doivent présenter une bonne étanchéité, tout en préservant une bonne accessibilité pour les opérations de montage, démontage, et de maintenance, en particulier en ce qui concerne la liaison d'entrée sur le refroidisseur du circuit.  Because of the functional constraints which are related to it, on the one hand, and on the other hand dimensional and congestion constraints of the environment in which such a circuit is placed, the links between the elements composing said circuit must have a good seal, while maintaining good accessibility for assembly, disassembly, and maintenance operations, particularly with respect to the input connection to the circuit cooler.

D'une manière générale, et comme le présente, par exemple, le document US20040177609, les liaisons sont réalisées au moyen de brides plates percées de deux orifices sensiblement opposés et destinés à accueillir deux vis de serrage. L'étanchéité est, dans ce cas, généralement obtenue au moyen d'un joint approprié glissé entre les brides des éléments à raccorder, de préférence un joint métallique. Un tel système impose toutefois, pour les opérations de montage, démontage, et de maintenance, un double accès à la bride de liaison, pour le passage, notamment, de l'outil de vissage et de dévissage desdites vis de serrage.  In general, and as shown, for example, in US20040177609, the connections are made by means of flat flanges pierced with two orifices substantially opposite and intended to accommodate two clamping screws. The seal is, in this case, generally obtained by means of an appropriate seal slid between the flanges of the elements to be connected, preferably a metal seal. Such a system, however, requires, for assembly operations, disassembly, and maintenance, double access to the connecting flange, for the passage, in particular, the tool for screwing and unscrewing said clamping screws.

Le document US5918912 présente une alternative à ce type de montage, pour la liaison de la tête de cylindre du moteur d'un véhicule automobile aux tubulures d'évacuation des gaz d'échappement dudit moteur. Dans cet agencement, la tête de cylindre est conçue de manière à former, au voisinage des différentes liaisons sur lesdites tubulures d'évacuation, un ensemble de poches dans lesquelles vient s'insérer une partie des brides de liaison de ces tubulures.  The document US5918912 presents an alternative to this type of assembly, for the connection of the engine cylinder head of a motor vehicle to the exhaust pipes of said engine exhaust. In this arrangement, the cylinder head is designed to form, in the vicinity of the various connections on said discharge pipes, a set of pockets in which is inserted a portion of the connecting flanges of these pipes.

La partie sensiblement opposée desdites brides est alors maintenue contre ladite tête de cylindre par une pièce appropriée unique (sensiblement une plaque) rapportée par vissage sur ladite tête de cylindre. Un ensemble de ressorts et de joints, placés entre lesdites brides et ladite tête de cylindre, permet d'assurer l'étanchéité.  The substantially opposite portion of said flanges is then held against said cylinder head by a single appropriate piece (substantially a plate) attached by screwing on said cylinder head. A set of springs and seals, placed between said flanges and said cylinder head, makes it possible to seal.

Un tel agencement, toutefois, impose une conformation particulière de la tête de cylindre, ce qui en complique la réalisation et en augmente le coût de fabrication. II implique de plus l'utilisation de joints présentant des propriétés d'élasticité spécifiques, ou le couplage de joints classiques à un dispositif élastique afin de maintenir une pression constante sur la surface de contact desdites brides avec ladite tête de cylindre.  Such an arrangement, however, imposes a particular conformation of the cylinder head, which complicates the implementation and increases the cost of manufacture. It further involves the use of seals having specific elastic properties, or the coupling of conventional seals to an elastic device to maintain a constant pressure on the contact surface of said flanges with said cylinder head.

La présente invention a pour but de proposer un dispositif de liaison de réalisation simple, d'un montage et d'un accès aisés.  The object of the present invention is to propose a connection device of simple construction, easy assembly and easy access.

L'invention atteint son but grâce à un dispositif pour la liaison d'un tube muni à une extrémité d'une première bride, et d'un élément de ligne d'échappement comportant un conduit destiné à être en vis-à-vis du conduit du tube et une surface d'appui destinée à être en contact avec la bride, le dispositif comportant un moyen de fixation du tube contre la surface d'appui de l'élément, caractérisé en ce que le moyen de fixation comporte une deuxième bride, mobile, appuyant sur la première bride, la deuxième bride étant fixée par deux éléments de fixation, l'un étant solidaire de l'élément et l'autre étant constitué d'une vis se logeant dans un taraudage réalisé dans l'élément.  The invention achieves its goal by means of a device for connecting a tube provided at one end with a first flange, and an exhaust line element comprising a duct intended to be opposite the conduit of the tube and a bearing surface intended to be in contact with the flange, the device comprising a means of fixing the tube against the bearing surface of the element, characterized in that the fastening means comprises a second flange. , mobile, pressing the first flange, the second flange being fixed by two fasteners, one being secured to the element and the other being constituted by a screw being housed in a tapping formed in the element.

L'invention peut également présenter une ou plusieurs des caractéristiques suivantes: la deuxième bride peut comporter une section en forme de Vé appuyant contre la première bride, l'élément de fixation solidaire de l'élément peut être un appendice s'étendant sensiblement dans la direction du tube et dont la section a sensiblement la forme d'un T, la deuxième bride étant insérée entre la première bride et la partie horizontale du T constituant l'appendice, la surface d'appui de l'élément de ligne d'échappement peut être portée par une troisième bride, la troisième bride appuyant contre la première bride du tube et comportant l'élément de fixation solidaire de l'élément de ligne d'échappement.  The invention may also have one or more of the following features: the second flange may comprise a Vee-shaped section pressing against the first flange, the fastening element integral with the element may be an appendix extending substantially in the direction of the tube and whose section has substantially the shape of a T, the second flange being inserted between the first flange and the horizontal portion of the T constituting the appendix, the bearing surface of the exhaust line element can be carried by a third flange, the third flange pressing against the first flange of the tube and having the fastening element integral with the exhaust line element.

- La figure 5 est vue de côté du dispositif de liaison selon l'invention Les figures 1 et 5 présentent schématiquement l'assemblage selon l'invention: un tube 1 est muni à une extrémité d'une première bride 3. Il est destiné à être lié avec un élément E de ligne d'échappement comportant un conduit (non représenté) destiné à être en vis-à-vis du conduit (non représenté) du tube 1 et une surface d'appui destinée à être en contact avec la bride 3. Le dispositif de liaison comporte un moyen de fixation du tube contre la surface d'appui de l'élément E. Selon l'invention, le moyen de fixation comporte une deuxième bride 7, mobile, appuyant sur la première bride 3, la deuxième bride 7 étant fixée par deux éléments de fixation, l'un étant solidaire de l'élément E et l'autre étant constitué d'une vis se logeant dans un taraudage réalisé dans l'élément E. La deuxième bride 7 comporte une section en forme de Vé, la pointe du Vé appuyant contre la première bride 3.  FIG. 5 is a side view of the connection device according to the invention. FIGS. 1 and 5 show schematically the assembly according to the invention: a tube 1 is provided at one end with a first flange 3. It is intended for be linked with an exhaust line element E comprising a duct (not shown) intended to face the duct (not shown) of the tube 1 and a bearing surface intended to be in contact with the flange 3. The connecting device comprises means for fixing the tube against the bearing surface of the element E. According to the invention, the fastening means comprises a second flange 7, movable, pressing on the first flange 3, the second flange 7 being fixed by two fixing elements, one being secured to the element E and the other consisting of a screw housed in a tapping formed in the element E. The second flange 7 has a section in the shape of Ve, the tip of Ve pressing against the first flange 3.

La surface d'appui de l'élément E de ligne d'échappement est portée par une troisième bride 4. L'élément E comporte une partie sensiblement tubulaire 2, et la troisième bride 4 est fixée à une extrémité de cette partie 2. La troisième bride 4 appuie contre la première bride 3 du tube 1 et comporte l'élément de fixation solidaire de l'élément E. La troisième bride 4 se présente sensiblement sous la forme d'un disque principal 4' prolongé par deux disques secondaires 4" de plus petit diamètre, dont les centres sont diamétralement opposés par rapport audit disque principal 4', et reliés audit disque principal 4' par les tangentes communes auxdits disques principal et secondaires 4' et 4", la surface de ladite troisième bride 4 ayant ainsi sensiblement, en vue de dessus selon une direction perpendiculaire à son plan de contact avec la première bride 3, la forme d'un oeil. La première bride 3 se présente sensiblement sous la forme d'un disque, dont le diamètre est sensiblement égal à celui dudit disque principal 4' composant ladite troisième bride 4.  The bearing surface of the exhaust line element E is carried by a third flange 4. The element E comprises a substantially tubular part 2, and the third flange 4 is fixed at one end of this part 2. The third flange 4 bears against the first flange 3 of the tube 1 and comprises the fastening element secured to the element E. The third flange 4 is substantially in the form of a main disk 4 'extended by two secondary disks 4 " of smaller diameter, whose centers are diametrically opposed with respect to said main disk 4 ', and connected to said main disk 4' by the tangents common to said primary and secondary disks 4 'and 4 ", the surface of said third flange 4 thus having substantially in plan view in a direction perpendicular to its plane of contact with the first flange 3, the shape of an eye. The first flange 3 is substantially in the form of a disk, whose diameter is substantially equal to that of said main disk 4 'constituting said third flange 4.

En référence aussi à la figure 2, l'un desdits disques secondaires 4" formant la troisième bride 4 comporte un orifice 5 destiné au passage d'une vis 10 liant le tube 1 et la partie sensiblement tubulaire 2 dudit élément E à raccorder: le mode de liaison sera décrit de manière plus détaillée ultérieurement. L'autre desdits disques secondaires 4" formant ladite troisième bride 4 comporte un élément de fixation solidaire de l'élément E. Cet élément de fixation est un appendice 6 qui est sensiblement en forme de T, et qui s'étend, selon une direction sensiblement parallèle à celle de l'axe local de ladite partie sensiblement tubulaire 2, vers le tube 1. Par ailleurs, l'appendice 6 est configuré et placé de telle manière que la partie verticale 6' du T le composant est tangente à une partie du pourtour extérieur de ladite première bride 3 dudit tube 1.  Referring also to Figure 2, one of said secondary disks 4 "forming the third flange 4 comprises an orifice 5 for the passage of a screw 10 connecting the tube 1 and the substantially tubular portion 2 of said element E to be connected: the link mode will be described in more detail later The other of said secondary disks 4 "forming said third flange 4 comprises a fastening element integral with the element E. This fastening element is an appendix 6 which is substantially shaped T, and which extends, in a direction substantially parallel to that of the local axis of said substantially tubular portion 2, to the tube 1. In addition, the appendix 6 is configured and placed in such a way that the vertical part 6 'of the T component is tangent to a portion of the outer periphery of said first flange 3 of said tube 1.

La deuxième bride 7, mobile, est insérée autour dudit tube 1, en amont de ladite première bride 3, entre ladite première bride 3 et la face inférieure 6" de la partie horizontale du T composant ledit appendice 6. La bride 7 a des dimensions extérieures et une forme sensiblement identiques à celles de ladite troisième bride 4.  The second flange 7, mobile, is inserted around said tube 1, upstream of said first flange 3, between said first flange 3 and the lower face 6 "of the horizontal portion of the T component said appendix 6. The flange 7 has dimensions outer and a shape substantially identical to those of said third flange 4.

En particulier, la bride 7 est constituée d'un disque principal 7' prolongé par deux disques secondaires 7" de plus petit diamètre, dont les centres respectifs sont diamétralement opposés par rapport audit disque principal 7'. L'un desdits disques secondaires 7" comporte un orifice 8 destiné au passage de la vis liant lesdits tube 1 et partie sensiblement tubulaire 2 dudit élément E à raccorder. L'autre disque secondaire 7" comporte, ainsi que le présente la figure 3, une échancrure 9 de forme complémentaire à celle de ladite partie verticale 6' du T constituant ledit appendice 6 (voir figure 3).  In particular, the flange 7 consists of a main disc 7 'extended by two smaller diameter secondary discs 7' ', the respective centers of which are diametrically opposed with respect to said main disc 7'. One of said secondary discs 7 '' has an orifice 8 for the passage of the screw connecting said tube 1 and substantially tubular portion 2 of said element E to be connected. The other secondary disk 7 "comprises, as shown in Figure 3, a notch 9 of complementary shape to that of said vertical portion 6 'of the T constituting said appendix 6 (see Figure 3).

Lors du montage dudit tube 1 sur ladite partie sensiblement tubulaire 2 dudit élément E, ladite échancrure 9, coopérant avec ladite partie verticale 6' du T constituant ledit appendice 6, constitue ainsi une articulation autour de laquelle ladite bride mobile 7 peut basculer lors de sa mise en place entre ladite première bride 3 et ladite face inférieure de ladite partie 6" dudit appendice 6. Avantageusement, la hauteur de ladite partie 6' dudit appendice 6 est sensiblement légèrement supérieure ou égale à la somme des épaisseurs de ladite première bride 3 et de ladite bride mobile 7, un léger jeu étant prévu de manière, d'une part, à permettre le basculement de ladite bride mobile 7, et, d'autre part, de permettre l'insertion, entre ladite première bride 3 et ladite troisième bride 4, d'un joint d'étanchéité classique.  When mounting said tube 1 on said substantially tubular portion 2 of said element E, said notch 9, cooperating with said vertical portion 6 'of the T constituting said appendix 6, thus constitutes a hinge about which said mobile flange 7 can tilt during its placing between said first flange 3 and said lower face of said portion 6 "of said appendix 6. Advantageously, the height of said portion 6 'of said appendix 6 is substantially greater than or equal to the sum of the thicknesses of said first flange 3 and of said mobile flange 7, a slight clearance being provided so as, on the one hand, to allow the tilting of said movable flange 7, and, secondly, to allow insertion between said first flange 3 and said third flange 4, a conventional gasket.

Lesdits orifices 5 et 8 étant alors alignés, il devient alors possible, par insertion d'une vis 10 dans ces dits orifices, de lier entre eux lesdits tube 1 et partie sensiblement tubulaire 2 dudit élément E. Ladite première bride 3 est ainsi prise en sandwich entre ladite troisième bride 4 et ladite bride mobile 7 (voir figure 4), l'effort de serrage étant ainsi uniformément réparti sur la surface de ladite première bride 3. De plus, un des avantages de l'invention est que l'on a besoin de n'avoir accès qu'à la seule vis de fixation du dispositif.  Said orifices 5 and 8 then being aligned, it then becomes possible, by inserting a screw 10 into said orifices, to bond said tubes 1 and substantially tubular portion 2 of said element E together. Said first flange 3 is thus taken into consideration. sandwich between said third flange 4 and said movable flange 7 (see Figure 4), the clamping force thus being uniformly distributed over the surface of said first flange 3. In addition, one of the advantages of the invention is that one needs to have access to only the fixing screw of the device.
