Abstract

The matrix for a catalyst to be used as purifier of the exhaust gases of motor vehicle engines consists of a corrugated and a plain metal strip, lined with a catalyst and wound into a roll for welding to a sleeve and into the exhaust pipe. For the last turn of the roll, the plain strip is reduced in width to leave the sleeve to be welded to the corrugated strip.

Description

La présente invention concerne une matrice de pot catalytique, constituée par deux bandes métalliques, une ondulée et une lisse, revetues de catalyseur et enroulées-sensiblement en cvlindre de fanon que la bande métallique lisse forme la peau, le corps ainsi obtenu étant partiellement inséré dans un manchon métallique et brasé sur ce dernier. The present invention relates to a catalytic converter matrix, consisting of two metal strips, one corrugated and one smooth, coated with catalyst and wound-substantially in bend of bale that the smooth metallic strip forms the skin, the body thus obtained being partially inserted in a metal sleeve and brazed thereon.

Des pots catalytiques simples ou des micropots catalytiques de ce type sont connus. Ils sont introduits directement dans un tuyau d'echappeluer,t adapte à leurs dimensions eztérieures, puis soudés dans ce dernier, le manchon servant de butée lors de l'introduction du pot. Simple catalytic converters or catalytic micropots of this type are known. They are introduced directly into a pipe to escape, adapts to their eztérieur dimensions, then welded in the latter, the sleeve serving as a stop during the introduction of the pot.

Liinconvénient d'une telle matrice réside dans le fait que le manchon cylindrique est relativement difficile à relier à la peau lisse du corps cylindrique de la matrice. L'invention vise à remédier à cet inconvénient. The drawback of such a matrix lies in the fact that the cylindrical sleeve is relatively difficult to connect to the smooth skin of the cylindrical body of the matrix. The invention aims to remedy this drawback.

Selon une caractéristique essentielle de l'invention, la spire extérieure de la bande métallique lisse est formée par un tronçon d'extrémité dont la longueur est sensiblement égale à la circonférence du corps cylindrique et dont la largeur est égale à la longueur axiale de la partie non insérée dans le manchon; et la spire extérieure de la bande métallique ondulée, située dans le manchon, est reliée directement à ce dernier. Par suite de cette réalisation, la bande métallique lisse constitue la peau uniquement dans la zone non enfichée dans le manchon. Un secteur cylindrique, dont la couche extérieure est formée par la bande ondulée, pénètre par suite dans le manchon. La matrice enroulée s'applique ainsi linéairement sur la bande ondulée et essentiellement suivant la direction axiale sur la circonférence intérieure du manchon.Son brasage sur le manchon est ainsi très simple car la brasure peut s'écouler dans les fentes cunéiformes comprises entre les ondulations et le manchon, et atteindre régulièrement tous les points de contact. According to an essential characteristic of the invention, the outer turn of the smooth metal strip is formed by an end section whose length is substantially equal to the circumference of the cylindrical body and whose width is equal to the axial length of the part not inserted in the sleeve; and the outer coil of the corrugated metal strip, located in the sleeve, is connected directly to the latter. As a result of this embodiment, the smooth metal strip constitutes the skin only in the area not plugged into the sleeve. A cylindrical sector, the outer layer of which is formed by the corrugated strip, consequently penetrates into the sleeve. The wound matrix is thus applied linearly on the corrugated strip and essentially in the axial direction on the inner circumference of the sleeve. Its soldering on the sleeve is thus very simple because the solder can flow in the wedge-shaped slots between the undulations and the sleeve, and regularly reach all contact points.

Selon une autre caractéristique de l'invention, les extrémités de l'enveloppe du manchon se chevauchent mutuellement et sont brasées. Cette réalisation présente l'avantage de former entre les deux zones cylindriques de la matrice un net rebord de butée, qu'ii est d'une part facile de positionner et qui présente d'autre part l'avantage que le rebord de la matrice ainsi formée et insérée dans le tuyau d'échappement peut etre soudé facilement et régulièrement audit tuyau qui l'entoure. According to another characteristic of the invention, the ends of the envelope of the sleeve overlap each other and are brazed. This embodiment has the advantage of forming a clear stop flange between the two cylindrical zones of the matrix, which it is easy to position on the one hand and which has the advantage that the matrix flange thus formed and inserted in the exhaust pipe can be welded easily and regularly to said pipe which surrounds it.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description détaillée ci-dessous d'exemples de réalisation et du dessin annexé sur lequel la figure 1 est une élévation latérale avec coupe partielle d'une nouvelle matrice de pot catalytique; la figure 2 est l'élévation frontale de la forme de réalisation selon figure 1, vue dans le sens de la flèche II; la figure 3 représente la matrice selon figures 1 et 2 mentée dans un tronçon de tuyau d'échappement; la figure 4 représente une variante du manchon de la forme de réalisation selon figure 1, avec une enveloppe enroulée dont les extrémités se chevauchent; la figure 5 représente un manchon semblable à celui de la figure 4, avec une enveloppe dont les extrémités sont toutefois aboutées; la figure 6 représente une variante de réalisation d'une matrice, semblable à celle de la figure 1, mais dans laquelle le bord fron tal intérieur du manchon est replié vers 1 'extérieur; et la figure 7 représente schématiquement et en Perspective l'enrou- lement d'une matrice selon l'invention, pendant la phase finale et sans manchon mis en place. Other characteristics and advantages of the invention will be better understood with the aid of the detailed description below of exemplary embodiments and of the appended drawing in which FIG. 1 is a side elevation with partial section of a new die catalytic converter; Figure 2 is the front elevation of the embodiment according to Figure 1, viewed in the direction of arrow II; FIG. 3 represents the matrix according to FIGS. 1 and 2 lying in a section of exhaust pipe; FIG. 4 represents a variant of the sleeve of the embodiment according to FIG. 1, with a rolled envelope whose ends overlap; 5 shows a sleeve similar to that of Figure 4, with an envelope whose ends are however butted; FIG. 6 represents an alternative embodiment of a matrix, similar to that of FIG. 1, but in which the internal fringe edge of the sleeve is folded outwards; and FIG. 7 schematically and in perspective shows the winding of a matrix according to the invention, during the final phase and without the sleeve in place.

Les figures 1 et 2 représentent une matrice de pot catalytique utilisé pour l'épuration des gaz d'échappement d'un véhicule. La matrice est constituée par une bande métallique 2 ondulée perpendiculairement à son grand axe et une bande métallique lisse 3 de même largeur b qui, selon figure 7, sont superposées et enroulées sous forme d'un corps cylindrique 1 de façon que la bande métallique lisse 3 se trouve à l'extérieur de la dernière spire et constitue la peau. Figures 1 and 2 show a catalytic converter matrix used for the purification of vehicle exhaust gases. The matrix consists of a metal strip 2 corrugated perpendicular to its long axis and a smooth metal strip 3 of the same width b which, according to FIG. 7, are superimposed and wound in the form of a cylindrical body 1 so that the smooth metal strip 3 is located outside the last turn and constitutes the skin.

Comme le montre en particulier la figure 7, la bande métallique 3 lisse comprend un tronçon d'extrémité 3' de largeur a inférieure à la largeur totale b des deux bandes 2 et 3. Le tronçon d'extrémité 31 présente une longueur U sensiblement égale à la circonférence du corps cylindrique 1, c'est-à-dire environ la longueur
U = d x dans l'exemple de réalisation considéré, d étant le diamètre extérieur du corps cylindrique 1 représenté sur la figure 2.As shown in particular in FIG. 7, the smooth metal strip 3 comprises an end section 3 'of width a less than the total width b of the two strips 2 and 3. The end section 31 has a length U substantially equal at the circumference of the cylindrical body 1, i.e. about the length
U = dx in the embodiment considered, d being the outside diameter of the cylindrical body 1 shown in FIG. 2.

Lorsque le corps cylindrique est produit par enroulement de ces deux bandes 2 et 3, on obtient donc une zone la du corps cylindrique 1, de longueur axiale a et présentant une peau lisse, et une zone lb de longueur axiale b - a, dans laquelle la bande ondulée 2 forme la couche extérieure. Cette zone lb est, dans l'exemple de réalisation des figures 1 à 3, enfichée dans un manchon 4 constitué par un tronçon de tube, puis brasée sur ce dernier. te brasage s'effectue de façon très simple et très sure, car la brasure peut pénétrer dans les fentes cunéiformes comprises entre la circonférence intérieure du manchon 4 et la bande ondulée 2 extérieure, et bien se répartir.When the cylindrical body is produced by winding these two bands 2 and 3, there is therefore obtained a region la of the cylindrical body 1, of axial length a and having a smooth skin, and a region lb of axial length b - a, in which the corrugated strip 2 forms the outer layer. This zone 1b is, in the embodiment of FIGS. 1 to 3, inserted in a sleeve 4 constituted by a section of tube, then brazed on the latter. brazing is carried out in a very simple and very safe way, because the brazing can penetrate into the wedge-shaped slots comprised between the inner circumference of the sleeve 4 and the outer corrugated strip 2, and be well distributed.

Le corps 1, ainsi muni d'un épaulement formé par une arête frontale 6 du manchon et constituant une sorte de cartouche pour gaz d'échappement, est ensuite - de façon connue - inséré axialement dans un tuyau d'échappement 8, muni d'un épaulement 9 correspondant, puis bloqué ou soudé sur ledit tuyau. The body 1, thus provided with a shoulder formed by a front edge 6 of the sleeve and constituting a kind of cartridge for exhaust gas, is then - in known manner - inserted axially in an exhaust pipe 8, provided with a corresponding shoulder 9, then blocked or welded to said pipe.

Le manchon peut, comme sur les figures 1 à 3, etre constitué par un morceau de tuyau cylindrique découpé. Il eput aussi, comme indiqué sur les figures 4 et 5, être constitué par une enveloppe 5 enroulée dont les extrémités 5c, 5d se chevauchent, puis sont brasées ou soudées, ou aboutées puis également soudées ou brasées, comme indiqué à l'aide des extrémités 5a et 5b de la figure 5. The sleeve can, as in Figures 1 to 3, be constituted by a piece of cut cylindrical pipe. It is also possible, as shown in FIGS. 4 and 5, to be constituted by a coiled envelope 5 whose ends 5c, 5d overlap, then are brazed or welded, or butted and then also welded or brazed, as indicated using ends 5a and 5b of figure 5.

La figure 6 représente une variante de matrice dans laquelle l'arête frontale 6 du manchon 4", située dans la zone circonférentielle du corps cylindrique 1, présente un bord 7 replié vers l'extérieur, servant de tulipe pour l'insertion de la matrice et se prêtant aussi au soudage sur le tuyau d'échappement 8. Lors de l'insertion axiale de la matrice finie dans le tuyau d'échappement 8, ce bord 7 s'applique énergiquement sur la circonférence intérieure de ce dernier et constitue une butée sûre même en présence de tolérances sur le diamètre. La manchon 4 est soudé sur le tuyau d'échap pement 8, même dans la forme de réalisation selon figure 3. Il fournit le matériau plus épais nécessaire pour le soudage et ne sert donc pas uniquement de butée axiale. FIG. 6 represents a variant of a matrix in which the front edge 6 of the sleeve 4 ", located in the circumferential zone of the cylindrical body 1, has an edge 7 folded outwards, serving as a tulip for the insertion of the matrix and also suitable for welding on the exhaust pipe 8. During the axial insertion of the finished matrix into the exhaust pipe 8, this edge 7 is applied energetically on the inner circumference of the latter and constitutes a stop safe even in the presence of tolerances on the diameter The sleeve 4 is welded to the exhaust pipe 8, even in the embodiment according to Figure 3. It provides the thicker material necessary for welding and is therefore not only used axial stop.

N Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art au principe et aux dispositifs qui viennent d'être décrits uniquement à titre d'exemples non limitatifs, sans sortir du cadre de l'invention.  N Of course, various modifications can be made by those skilled in the art to the principle and to the devices which have just been described only by way of nonlimiting examples, without departing from the scope of the invention.
