Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un système de fixation de deux organes de dépollution dans une ligne d'échappement de moteur de véhicule auto- mobile.  The present invention relates to a system for fixing two pollution control devices in an exhaust line of an automobile vehicle engine.

On connaît déjà dans l'état de la technique, des systèmes de fixation de ce type qui comportent deux brides fixées sur les bords d'extrémité en regard de ces organes de dépollution et qui sont munies sur leurs faces en regard de surfaces de contact entre lesquelles sont disposés des moyens d'étanchéité.  Fixing systems of this type are already known in the state of the art, which comprise two flanges fixed on the end edges facing these pollution control members and which are provided on their opposite faces with contact surfaces between which are arranged sealing means.

Ces brides sont associées à des moyens de serrage de celles-ci l'une sur l'autre pour assurer leur fixation et l'étanchéité entre les deux organes.  These flanges are associated with means for clamping them one on the other to ensure their fixing and sealing between the two members.

De façon générale, ces moyens de fixation comprennent par exemple des boulons traversant des trous correspondants de ces brides.  Generally, these fixing means comprise for example bolts passing through corresponding holes in these flanges.

Cependant, ces systèmes de fixation présentent un certain nombre d'inconvénients car les organes de dépollution doivent pouvoir être démontés facilement en vue par exemple de leur nettoyage ou de leur remplacement.  However, these fastening systems have a certain number of drawbacks because the pollution control devices must be able to be easily dismantled with a view, for example, to cleaning or replacing them.

De plus, de nombreux capteurs et sondes sont nécessaires au bon fonctionnement de ces organes, tels que par exemple des capteurs de pression, de température, etc...  In addition, many sensors and probes are necessary for the proper functioning of these organs, such as for example pressure, temperature sensors, etc.

Or, les systèmes à brides et boulons actuellement utilisés sont lourds, encombrants, coûteux et difficiles à manipuler, notamment lors de démontages et de remontages successifs.  However, the flange and bolt systems currently used are heavy, bulky, expensive and difficult to handle, especially during successive disassembly and reassembly.

Le but de l'invention est donc de résoudre ces problèmes.  The object of the invention is therefore to solve these problems.

A cet effet, l'invention a pour objet un système de fixation de deux organes de dépollution dans une ligne d'échappement de moteur de véhicule automobile, du type comportant deux brides fixées sur les bords d'extrémité en regard de ces organes et munies sur leurs faces en regard de surfaces de contact entre lesquelles sont disposés des moyens d'étanchéité, et associées à des moyens de serrage de celles-ci l'une contre l'autre, caractérisé en ce que les brides comprennent sur leurs faces opposées, des surfaces inclinées et en ce que les moyens de serrage comprennent un collier de section de forme générale en V adapté pour s'étendre autour des brides et pour coopérer avec les surfaces inclinées de celles-ci afin de les serrer l'une contre l'autre.  To this end, the subject of the invention is a system for fixing two depollution members in an exhaust line of a motor vehicle engine, of the type comprising two flanges fixed on the end edges facing these members and provided on their faces opposite contact surfaces between which are sealing means, and associated with means for clamping the latter one against the other, characterized in that the flanges comprise on their opposite faces, inclined surfaces and in that the clamping means comprise a generally V-shaped section collar adapted to extend around the flanges and to cooperate with the inclined surfaces of the latter in order to clamp them one against the other.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :  The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings, in which:

<Desc/Clms Page number 2><Desc / Clms Page number 2>

- la Fig. 1 illustre la fixation de deux organes de dépollution grâce à un système de fixation selon l'invention ; - les Figs. 2 et 3 représentent des vues respectivement éclatée et en position de montage d'un exemple de réalisation d'un système de fixation selon l'invention ; et la Fig. 4 représente une vue en coupe d'une partie de celui-ci.  - Fig. 1 illustrates the fixing of two depollution organs using a fixing system according to the invention; - Figs. 2 and 3 show views respectively exploded and in the mounting position of an embodiment of a fixing system according to the invention; and Fig. 4 shows a sectional view of part of it.

On a en effet représenté sur ces figures, un système de fixation de deux organes de dépollution dans une ligne d'échappement d'un moteur de véhicule automobile.  There is indeed shown in these figures, a system for fixing two pollution control elements in an exhaust line of a motor vehicle engine.

Ces organes sont par exemple désignés par les références générales 1 et 2 sur la figure 1 et comprennent par exemple un catalyseur, un filtre à particules, etc...  These bodies are for example designated by the general references 1 and 2 in FIG. 1 and comprise for example a catalyst, a particle filter, etc.

Selon l'invention, le système de fixation comporte deux brides, par exemple 3 et 4, fixées sur les bords d'extrémité en regard de ces organes et munies sur leurs faces en regard de surfaces de contact, par exemple 5 et 6, entre lesquelles sont disposés des moyens d'étanchéité, par exemple 7, de type classique.  According to the invention, the fixing system comprises two flanges, for example 3 and 4, fixed on the end edges facing these members and provided on their facing faces with contact surfaces, for example 5 and 6, between which are arranged sealing means, for example 7, of conventional type.

Ces brides sont associées à des moyens de serrage de celles-ci l'une contre l'autre.  These flanges are associated with means for clamping them one against the other.

En fait, les brides comportent sur leurs faces opposées, des surfaces inclinées telles que les surfaces 8 et 9 et les moyens de serrage comprennent un collier 10 de section de forme générale en V, adapté pour s'étendre autour des brides et pour coopérer avec les surfaces inclinées de celles-ci afin de les serrer l'une contre l'autre.  In fact, the flanges have on their opposite faces, inclined surfaces such as the surfaces 8 and 9 and the clamping means comprise a collar 10 of generally V-shaped section, adapted to extend around the flanges and to cooperate with the inclined surfaces of these in order to clamp them together.

Dans l'exemple de réalisation décrit, le collier est un collier ouvert dont les extrémités sont associées à des moyens 11 de rapprochement pour serrer celui-ci sur les brides.  In the embodiment described, the collar is an open collar, the ends of which are associated with approximation means 11 for tightening the latter on the flanges.

En fait, ces moyens de rapprochement peuvent comporter des moyens de vissage tangentiels complémentaires des extrémités du collier.  In fact, these approximation means may include tangential screwing means complementary to the ends of the collar.

Chaque extrémité du collier est alors munie d'une oreille percée respectivement 12 et 13 de passage par exemple d'une vis 14, adaptée pour coopérer avec un écrou 15 pour assurer lors du vissage, le serrage de ce collier autour des brides et donc le serrage des surfaces de contact de celles-ci contre les moyens d'étanchéité 7.  Each end of the collar is then provided with a pierced ear respectively 12 and 13 for passage, for example of a screw 14, adapted to cooperate with a nut 15 to ensure during tightening, the tightening of this collar around the flanges and therefore the tightening their contact surfaces against the sealing means 7.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

De plus, ces surfaces en regard des faces des brides peuvent comporter des portions en relief telles que les portions 16 et 17 illustrées sur la figure 4.  In addition, these surfaces facing the faces of the flanges may include raised portions such as the portions 16 and 17 illustrated in FIG. 4.

Ceci permet d'assurer un positionnement correct des brides l'une par rapport à l'autre et de former une chicane d'optimisation de l'étanchéité entre ces brides.  This ensures correct positioning of the flanges relative to each other and to form a baffle for optimizing the seal between these flanges.

Au moins l'une des brides, comme par exemple la bride 3, peut également comporter des moyens de réception de moyens d'acquisition d'informations relatives au fonctionnement des organes de dépollution, tels que les capteurs et sondes décrits précédemment.  At least one of the flanges, such as for example the flange 3, may also include means for receiving means for acquiring information relating to the operation of the pollution control devices, such as the sensors and probes described above.

A cet effet, les moyens de réception peuvent par exemple comporter un bloc de montage 18 de ces moyens, munis de trous taraudés de vissage en position de ces moyens d'acquisition dont deux 19 et 20 sont illustrés sur ces figures.  To this end, the receiving means may for example comprise a mounting block 18 of these means, provided with threaded screw holes in the position of these acquisition means, two of which 19 and 20 are illustrated in these figures.

Une telle structure peut être utilisée pour une ligne d'échappement d'un moteur à essence, Diesel ou autre, turbocompressé ou non.  Such a structure can be used for an exhaust line of a petrol, diesel or other engine, turbocharged or not.

Elle peut également être utilisée pour assurer la fixation de n'importe quels types d'organes de dépollution entre eux, tels que par exemple des catalyseurs, des filtres à particules, des pièges à NOx etc..  It can also be used to ensure the attachment of any type of pollution control device to one another, such as, for example, catalysts, particle filters, NOx traps, etc.

Ceci permet alors un montage et un démontage aisés de ces organes de dépollution, ce qui facilite par exemple les opérations d'entretien des lignes d'échappement. This then allows easy assembly and disassembly of these pollution control devices, which facilitates for example the maintenance operations of the exhaust lines.
