La ligne d'échappement et le collecteur d'échappement sont reliés par des brides associées 25 avantageusement à une bague d'étanchéité. An exhaust system of a motor vehicle conventionally comprises at least one exhaust line, which can be removable, especially during the after-sales or repair phase, and an exhaust manifold, fixed on the engine of the vehicle. . The exhaust line and the exhaust manifold are connected by flanges advantageously associated with a sealing ring.

Comme illustré sur les figures 1 et 2, représentant schématiquement un système d'échappement 10 selon l'art antérieur, la ligne d'échappement 11 est classiquement équipée d'une bride d'échappement sphérique 12, à son 30 extrémité reliée au collecteur d'échappement 13, la partie sphérique de la bride 12 étant orientée en direction de la ligne d'échappement 11. Par ailleurs, le collecteur d'échappement 13 est muni d'une bride plate 14, destinée à se fixer5 sur la bride d'échappement 12, par l'intermédiaire, par exemple, de vis de fixation 15, et associée à une bague d'étanchéité 16, montée sur la bride plate 14 (figure 2) Cependant, un tel agencement du système d'échappement pose certains problèmes, plus particulièrement en après vente, un opérateur voulant changer la ligne d'échappement rencontre des difficultés à extraire la bague d'étanchéité placée sur le collecteur d'échappement. L'accessibilité à la bague d'étanchéité est donc problématique, notamment en cas de montage ou de démontage de la ligne d'échappement. As illustrated in Figures 1 and 2, schematically showing an exhaust system 10 according to the prior art, the exhaust line 11 is conventionally equipped with a spherical exhaust flange 12, at its end connected to the exhaust manifold. 13, the spherical portion of the flange 12 being oriented towards the exhaust line 11. Moreover, the exhaust manifold 13 is provided with a flat flange 14, intended to be fixed on the flange of exhaust 12, through, for example, fixing screw 15, and associated with a sealing ring 16, mounted on the flat flange 14 (Figure 2) However, such an arrangement of the exhaust system poses certain problems , especially after sales, an operator wanting to change the exhaust line has difficulty extracting the sealing ring placed on the exhaust manifold. Accessibility to the sealing ring is therefore problematic, especially in case of assembly or disassembly of the exhaust line.

Description de modes particuliers de réalisation FIG. 6 schematically represents an enlarged sectional view of detail B of FIG. 4, illustrating the positioning of a sealing ring on an exhaust line of an embodiment variant of an exhaust system according to FIGS. 3 and 4. Description of particular embodiments

En référence aux figures 3 à 6, l'agencement du système d'échappement 10 selon l'invention consiste à inverser le positionnement des éléments 15 constituants le système d'échappement, à savoir la partie sphérique sur le collecteur d'échappement et la bague d'étanchéité sur la ligne d'échappement. Sur la figure 3, la ligne d'échappement 11 est ainsi munie de la bride plate 14 et le collecteur d'échappement 13 est muni de la bride d'échappement 12 sphérique, les deux brides 12 et 14 étant fixées, par exemple, par des vis 15. 20 Le système d'échappement 10 comporte toujours la bague d'étanchéité, mais celle-ci est positionnée sur la ligne d'échappement 11, comme décrit ci-après (figures 4 et 5). With reference to FIGS. 3 to 6, the arrangement of the exhaust system 10 according to the invention consists in reversing the positioning of the elements constituting the exhaust system, namely the spherical part on the exhaust manifold and the ring. sealing on the exhaust line. In FIG. 3, the exhaust line 11 is thus provided with the flat flange 14 and the exhaust manifold 13 is provided with the spherical exhaust flange 12, the two flanges 12 and 14 being fixed, for example, by The exhaust system 10 still includes the sealing ring, but this is positioned on the exhaust line 11, as described hereinafter (FIGS. 4 and 5).

Sur la figure 4, illustrant une vue en coupe partielle du système 25 d'échappement 10 selon l'invention, le collecteur d'échappement 13 est muni de la bride d'échappement 12 sphérique sur son extrémité coopérant avec la ligne d'échappement 11, la partie sphérique de la bride d'échappement 12 étant orientée en direction du collecteur d'échappement 13. La zone de réception de la ligne d'échappement 11 est donc relativement large, offrant ainsi plus de 30 simplicité pour le montage et le démontage de la ligne d'échappement 11 (figure 5). 10 Sur la figure 5, représentant le détail B de la figure 4, la bague d'étanchéité 16 est montée serrée sur la bride plate 14, elle-même montée sur l'extrémité de la ligne d'échappement 11 coopérant avec le collecteur d'échappement 13. La bride plate 14 comporte à cet effet une première portion 14a recevant la bague d'étanchéité 16 et une seconde portion 14b sensiblement bombée, faisant office de butée de support pour la bague d'étanchéité 16. In FIG. 4, illustrating a view in partial section of the exhaust system 10 according to the invention, the exhaust manifold 13 is provided with the spherical exhaust flange 12 on its end cooperating with the exhaust line 11. , the spherical part of the exhaust flange 12 being oriented towards the exhaust manifold 13. The zone of reception of the exhaust line 11 is therefore relatively wide, thus offering more simplicity for assembly and disassembly. of the exhaust line 11 (Figure 5). In FIG. 5, representing the detail B of FIG. 4, the sealing ring 16 is tightly mounted on the flat flange 14, itself mounted on the end of the exhaust line 11 cooperating with the collector. 13. The flat flange 14 comprises for this purpose a first portion 14a receiving the sealing ring 16 and a second substantially convex portion 14b acting as support abutment for the sealing ring 16.

La bague d'étanchéité 16 assure donc l'étanchéité de la liaison entre les deux brides 12 et 14 du système d'échappement 10. De plus, la bague d'étanchéité 16 est liée à la ligne d'échappement 11 qui est amovible, notamment en phase de manutention ou de réparation en après-vente. Il est ainsi possible de monter ou démonter la bague d'étanchéité 16 de façon beaucoup plus simple et plus rapide, notamment grâce à une meilleure accessibilité de la bague d'étanchéité 16, montée à l'extrémité de la ligne d'échappement 11. The sealing ring 16 thus seals the connection between the two flanges 12 and 14 of the exhaust system 10. In addition, the sealing ring 16 is connected to the exhaust line 11 which is removable, especially in the phase of handling or repair in after-sales. It is thus possible to mount or dismount the sealing ring 16 in a much simpler and faster way, in particular thanks to a better accessibility of the sealing ring 16, mounted at the end of the exhaust line 11.

Un tel agencement d'un système d'échappement 10 d'un véhicule automobile comme décrit ci-dessus permet donc de façon simple, rapide et économique de faciliter la manutention et la réparation de la bague d'étanchéité 16 et plus généralement de la ligne d'échappement 11, notamment en phase d'après-vente. Such an arrangement of an exhaust system 10 of a motor vehicle as described above thus allows a simple, fast and economical way to facilitate the handling and repair of the sealing ring 16 and more generally of the line exhaust 11, especially in the after-sales phase.

L'invention n'est pas limitée au mode de réalisation décrit ci-dessus. Les formes et les dimensions des différents éléments composant le système d'échappement 10 sont non limitatives et dépendent de la taille du véhicule sur lequel ils sont installés. Les vis de fixation 15 des brides 12 et 14 peuvent être remplacées par tout type de moyen de fixation démontable, tant que la ligne d'échappement 11 est amovible et tant que la bague d'étanchéité 16 est montée sur la ligne d'échappement 11 et la bride d'échappement sphérique 12 est montée sur le collecteur d'échappement 13. The invention is not limited to the embodiment described above. The shapes and dimensions of the various components of the exhaust system 10 are non-limiting and depend on the size of the vehicle on which they are installed. The fixing screws 15 of the flanges 12 and 14 may be replaced by any type of removable fastening means, as long as the exhaust line 11 is removable and as long as the sealing ring 16 is mounted on the exhaust line 11 and the spherical exhaust flange 12 is mounted on the exhaust manifold 13.

Par ailleurs, dans la variante de réalisation représentée sur la figure 6, le système d'échappement 10 peut notamment comporter un déflecteur 17 monté à l'intérieur de la bride d'échappement sphérique 12 et associé à la bague d'étanchéité 16. Le déflecteur 17 a notamment pour fonction de protéger la bague d'étanchéité 16 des flux de gaz à l'intérieur du système d'échappement 10. Furthermore, in the embodiment shown in Figure 6, the exhaust system 10 may include a deflector 17 mounted inside the spherical exhaust flange 12 and associated with the sealing ring 16. The The deflector 17 serves in particular to protect the sealing ring 16 from the gas flows inside the exhaust system 10.

L'invention s'applique à tous les types de véhicule automobile comportant un tel agencement du système d'échappement, à savoir avec un collecteur d'échappement muni de la bride d'échappement sphérique et avec une ligne d'échappement équipée de la bague d'étanchéité. The invention applies to all types of motor vehicle comprising such an arrangement of the exhaust system, namely with an exhaust manifold provided with the spherical exhaust flange and with an exhaust line equipped with the ring. sealing.
