Description

ASSEMBLAGE D'UN FLEXIBLE D'ECHAPPEMENT ET D'UN DISPOSITIF  ASSEMBLY OF AN EXHAUST HOSE AND A DEVICE
DE PROTECTION  PROTECTION
L'invention se rapporte à un assemblage d'un flexible d'échappement et d'un dispositif de protection dudit flexible. The invention relates to an assembly of an exhaust hose and a device for protecting said hose.
Actuellement, le flexible d'échappement est soudé à une bride évasée, qui vient se fixer par vissage sur une bride du collecteur d'échappement, côté moteur. Un dispositif de protection temporaire entoure le flexible pour notamment le protéger des agressions de soudure.  Currently, the exhaust hose is welded to a flared flange, which is fixed by screwing on a flange of the exhaust manifold, engine side. A temporary protection device surrounds the hose, in particular to protect it from welding attack.
Pour des raisons de gain économique et d'allègement cette liaison entre brides, est remplacée par une liaison « biconique » entre la bride du moteur et une extrémité du flexible, ladite liaison étant assurée par un collier circulaire de serrage.  For reasons of economic gain and lightening, this connection between flanges is replaced by a "biconical" connection between the motor flange and one end of the hose, said connection being provided by a circular clamping collar.
Pour garantir l'accessibilité au montage en usine, et au démontage en après-vente en garage, le collier doit être indexé en position sur le flexible. Autrement dit, le flexible et le collier sont assemblés à un endroit, puis sont acheminés ainsi assemblés à un autre endroit, où le flexible doit être monté sur un véhicule, ledit autre endroit pouvant par exemple être une zone particulière d'une chaîne d'assemblage dudit véhicule. Or, le protecteur actuel ne protège que le flexible et non pas le collier de serrage prémonté sur le flexible.  To guarantee accessibility to factory assembly, and to disassembly after-sales in the garage, the clamp must be indexed in position on the hose. In other words, the hose and the collar are assembled in one place, then are thus routed assembled in another place, where the hose is to be mounted on a vehicle, said other place can for example be a particular zone of a chain of assembly of said vehicle. However, the current protector protects only the hose and not the hose clamp pre-mounted on the hose.
Un dispositif de protection d'un assemblage selon l'invention, permet de garantir la protection à la fois du flexible et de du collier.  A device for protecting an assembly according to the invention makes it possible to guarantee protection both of the hose and of the collar.
L'invention a pour objet un assemblage d'un flexible d'échappement doté d'une extrémité évasée autour de laquelle est monté un collier de serrage, et d'un dispositif de protection dudit flexible.  The subject of the invention is an assembly of an exhaust hose having a flared end around which a clamp is mounted, and a device for protecting said hose.
Selon l'invention, le dispositif de protection comprend un boîtier doté de deux parties articulées autour d'un axe de rotation, lesdites deux parties articulées étant aptes à se rabattre l'une contre l'autre par pivotement pour envelopper l'intégralité du flexible, de l'extrémité évasée et du collier. De cette manière, le flexible et le collier de serrage peuvent être assemblés à part, puis être ensuite acheminés en toute protection sur les lieux de son montage dans un véhicule, par exemple le long d'une chaîne d'assemblage. Ce dispositif de protection est particulièrement efficace car il enserre le flexible, l'extrémité évasée et le collier. Préférentiellement, un tel boîtier est réalisé en matière plastique. Le collier de serrage a pour objet de fixer le flexible à une bride du moteur. De façon avantageuse, le boîtier une fois qu'il a été refermé sur le flexible, l'extrémité évasée et le collier, a une forme de champignon, avec un pied cylindrique droit prolongé par une tête élargie arrondie. De façon préférentielle, un tel boîtier présente une forme générale arrondie, sans présenter d'aspérité particulière et qui favorise une manipulation aisée. Les deux parties sont complémentaires de manière à former un boîtier creux une fois qu'elles ont été rabattues l'une contre l'autre. According to the invention, the protection device comprises a housing provided with two parts articulated around an axis of rotation, said two articulated parts being able to fold against one another by pivoting to wrap the entire hose. , the flared end and the collar. In this way, the hose and the hose clamp can be assembled separately, and then be safely transported to the places where it is mounted in a vehicle, for example along an assembly line. This device protection is particularly effective because it encloses the hose, the flared end and the collar. Preferably, such a housing is made of plastic. The purpose of the hose clamp is to secure the hose to a motor flange. Advantageously, the housing once it has been closed on the flexible, the flared end and the collar, has a mushroom shape, with a straight cylindrical foot extended by an enlarged rounded head. Preferably, such a case has a generally rounded shape, without presenting any particular roughness and which favors easy handling. The two parts are complementary so as to form a hollow housing once they have been folded against each other.
Avantageusement, le flexible est une pièce cylindrique creuse, le boîtier étant une pièce présentant un corps cylindrique creux destiné à envelopper le flexible, et une tête élargie fermée destinée à envelopper l'extrémité évasée et le collier. Ainsi, le profil du boîtier s'adapte au profil de l'ensemble constitué par le flexible, l'extrémité évasée et le collier de serrage. Autrement dit, le boîtier est dimensionné au plus juste de façon à envelopper entièrement cet ensemble, sans créer d'espaces libres superflus entre ledit boîtier et ledit ensemble.  Advantageously, the hose is a hollow cylindrical part, the housing being a part having a hollow cylindrical body intended to wrap the hose, and an enlarged closed head intended to wrap the flared end and the collar. Thus, the profile of the housing adapts to the profile of the assembly constituted by the flexible, the flared end and the clamp. In other words, the housing is dimensioned as tightly as possible so as to completely envelop this assembly, without creating superfluous free spaces between said housing and said assembly.
De façon préférentielle, l'axe de rotation est placé en appui contre l'extrémité évasée, les deux parties qui sont initialement placées de part et d'autre du flexible, étant rabattues sur celui-ci pour enserrer l'extrémité évasée pourvue du collier de serrage et ledit flexible.  Preferably, the axis of rotation is placed in abutment against the flared end, the two parts which are initially placed on either side of the hose, being folded over the latter to grip the flared end provided with the collar clamp and said flexible.
Préférentiellement, l'extrémité évasée est creuse, le boîtier comprenant un pion de centrage destiné à pénétrer dans ladite extrémité afin de prépositionner le dispositif de protection par rapport au flexible. En effet, afin de faciliter le montage du dispositif de protection autour du flexible, le pion de centrage est d'abord inséré dans l'extrémité évasée du flexible de façon à bien prépositionner le boîtier sur ledit flexible. Il devient alors aisé de rabattre les deux parties articulées l'une contre l'autre. Préférentiellement, le pion de centrage est cylindrique. De façon avantageuse, ledit pion est creux afin notamment d'alléger le boîtier de protection. De façon avantageuse, le pion de centrage est allongé et possède une collerette dont le plan est perpendiculaire à un axe longitudinal dudit pion, ladite collerette servant d'élément d'appui aux deux parties articulées qui se sont rabattues l'une contre l'autre. De cette manière, la collerette joue le rôle d'une entretoise apte à maintenir la tête élargie du dispositif de protection, dans une configuration arrondie. Preferably, the flared end is hollow, the housing comprising a centering pin intended to penetrate into said end in order to preposition the protection device relative to the hose. Indeed, in order to facilitate the mounting of the protection device around the hose, the centering pin is first inserted into the flared end of the hose so as to properly preposition the housing on said hose. It then becomes easy to fold the two articulated parts together. Preferably, the centering pin is cylindrical. Advantageously, said pin is hollow in particular in order to lighten the protective housing. Advantageously, the centering pin is elongated and has a collar whose plane is perpendicular to a longitudinal axis of said pin, said collar serving as a support element for the two articulated parts which have folded against each other. . In this way, the flange acts as a spacer capable of holding the enlarged head of the protection device, in a rounded configuration.
Avantageusement, les deux parties articulées disposent chacune de moyens de fixation aptes à coopérer ensemble, pour permettre de solidariser lesdites parties l'une à l'autre lorsqu'elles enveloppent le flexible, l'extrémité évasée et le collier. En effet, une fois que les deux parties ont été rabattues l'une contre l'autre en enveloppant l'ensemble constitué par le flexible, l'extrémité évasée et le collier de serrage, il est nécessaire qu'elles demeurent étroitement au contact l'une de l'autre afin de bien enserrer cet ensemble, et éliminer toute possibilité d'une ouverture intempestive. Ces moyens de fixation sont supposés être réversibles, afin de permettre au boîtier de protection de pouvoir être ôté facilement au moment du montage du flexible sur le moteur du véhicule concerné.  Advantageously, the two articulated parts each have fixing means able to cooperate together, to allow the said parts to be joined to one another when they surround the flexible, the flared end and the collar. Indeed, once the two parts have been folded against each other by wrapping the assembly constituted by the flexible, the flared end and the clamp, it is necessary that they remain closely in contact l 'one of the other to properly enclose this set, and eliminate any possibility of inadvertent opening. These fixing means are assumed to be reversible, in order to allow the protective casing to be able to be removed easily when the hose is mounted on the engine of the vehicle concerned.
De façon préférentielle, les moyens de fixation sont des clips en plastique. Il s'agit de moyens de fixation les plus simples et les plus rapides à mettre en œuvre, ne nécessitant ni un outillage particulier ni des manipulations compliquées.  Preferably, the fixing means are plastic clips. These are the simplest and quickest means of installation, requiring neither special tools nor complicated handling.
Préférentiellement, la tête élargie creuse est dimensionnée par rapport au collier de serrage de manière à laisser subsister un jeu entre ladite tête et ledit collier. Comme le collier de serrage est une pièce rapportée qui est juste placé sur l'extrémité évasée du flexible, il ne faut pas que le boîtier de protection interfère avec ledit collier, sous peine de déplacer ou d'endommager ledit collier au moindre choc produit sur ledit boîtier.  Preferably, the enlarged hollow head is dimensioned relative to the clamp so as to leave a clearance between said head and said collar. As the hose clamp is an insert which is just placed on the flared end of the hose, the protective casing must not interfere with said collar, under penalty of moving or damaging said collar at the slightest shock produced on said housing.
De façon avantageuse, le flexible présente une collerette d'extrémité, les deux parties articulées venant en appui contre la collerette lorsqu'elles enserrent le flexible, l'extrémité évasée et le collier, afin d'empêcher tout coulissement du dispositif de protection le long du flexible. A priori, une fois que le boîtier de protection a été monté autour du flexible, de l'extrémité évasée et du collier de serrage, rien ne l'empêche de coulisser le long dudit flexible. Cette collerette d'extrémité a pour but d'empêcher ce coulissement en constituant une butée d'arrêt pour le boîtier de protection. Advantageously, the hose has an end flange, the two articulated parts coming to bear against the flange when they enclose the hose, the flared end and the collar, in order to prevent any sliding of the protection device along hose. A priori, once that the protective casing has been mounted around the hose, the flared end and the clamp, nothing prevents it from sliding along said hose. The purpose of this end flange is to prevent this sliding by constituting a stop stop for the protective housing.
L'invention a pour autre objet un dispositif de protection pour la réalisation d'un assemblage selon l'invention.  Another subject of the invention is a protection device for producing an assembly according to the invention.
Selon l'invention, un dispositif de protection selon l'invention comprend un boîtier doté de deux parties articulées autour d'un axe de rotation, ledit assemblage comprenant un pion de centrage sur lequel est solidarisé ledit axe de rotation.  According to the invention, a protection device according to the invention comprises a housing provided with two parts articulated around an axis of rotation, said assembly comprising a centering pin on which said axis of rotation is secured.
Un assemblage selon l'invention présente l'avantage de comprendre un flexible directement prêt au montage, grâce à la présence du collier de serrage, et de pouvoir le transporter en toute sécurité sur les lieux se son montage grâce à un boîtier enveloppant l'intégralité du flexible et du collier de serrage. Le boîtier de protection mis en œuvre dans un assemble selon l'invention, a l'avantage d'être facile et rapide à placer autour du flexible, et de pouvoir être retiré tout aussi facilement et rapidement avant le montage du flexible sur un véhicule. Un tel boîtier de protection présente en outre l'avantage d'être dimensionné pour pouvoir protéger un flexible doté de son collier de serrage sans interférer avec ledit collier de serrage.  An assembly according to the invention has the advantage of comprising a hose directly ready for assembly, thanks to the presence of the clamp, and of being able to transport it safely on the premises if it is assembled thanks to a housing enveloping the whole. hose and hose clamp. The protective housing implemented in an assembly according to the invention has the advantage of being easy and quick to place around the hose, and of being able to be removed just as easily and quickly before mounting the hose on a vehicle. Such a protective casing also has the advantage of being dimensioned so as to be able to protect a hose provided with its hose clamp without interfering with said hose clamp.

An assembly 1 according to the invention comprises an assembly composed of a hose 2 provided with a flared end 3 and a clamp 4, and a protection device 5 intended to protect this assembly in order to route it in complete safety to a mounting point of said hose 2 on a vehicle engine.
En se référant aux figures 1, 2A et 2B, le flexible 2 est une pièce cylindrique creuse de forme allongée, possédant une extrémité évasée 3 constituée par une bride creuse insérée dans ledit flexible 2 et émergeant de celui-ci. La partie 6 de la bride 3 qui émerge du flexible 2 est constituée par une paroi de forme tronconique, la section transversale de ladite partie 6 croissant régulièrement au fur et à mesure que l'on s'éloigne du flexible 2. Le flexible 2 est destiné à venir se fixer sur une bride 7 d'un moteur, qui est une pièce cylindrique creuse possédant un bourrelet 8 annulaire élargissant localement ladite bride 7. Le bourrelet 8 est délimité par deux bords 9, 10 en continuité l'un de l'autre et inclinés l'un par rapport à l'autre, si bien que la section transversale du bourrelet 8 est maximale au niveau de sa circonférence centrale 11, et décroît progressivement de part et d'autre ladite circonférence centrale 11. Le flexible 2 vient se fixer dans la bride 7 du moteur au moyen d'une insertion de ladite bride 7 dans la bride 3 du flexible 2 jusqu'à ce que l'un des bords 9, 10 délimitant le bourrelet 8 vienne au contact d'une surface interne de la paroi tronconique de la partie émergeante de la bride 3 du flexible 2. Le collier 4 se présente sous la forme d'un anneau délimité par deux bords 12, 13 de sorte que la section transversale dudit anneau est maximale au niveau de sa circonférence centrale et décroît progressivement de part et d'autre de ladite circonférence centrale. Cette anneau 4 vient coiffer le bourrelet 8 de la bride 7 du moteur, et la paroi tronconique 6 de la bride 3 du flexible 2, un serrage dudit collier 4 plaquant ladite paroi tronconique 6 contre l'un des bords 9, 10 délimitant ledit bourrelet 8. Referring to Figures 1, 2A and 2B, the hose 2 is a hollow cylindrical piece of elongated shape, having a flared end 3 constituted by a hollow flange inserted in said hose 2 and emerging from it. The part 6 of the flange 3 which emerges from the flexible 2 is constituted by a wall of frustoconical shape, the cross section of said part 6 increasing regularly as one moves away from the flexible 2. The flexible 2 is intended to be fixed on a flange 7 of an engine, which is a hollow cylindrical part having an annular bead 8 locally widening said flange 7. The bead 8 is delimited by two edges 9, 10 in continuity of one another and inclined with respect to each other, so that the cross section of the bead 8 is maximum at its central circumference 11, and decreases progressively on either side of said circumference central 11. The flexible 2 is fixed in the flange 7 of the motor by means of an insertion of said flange 7 in the flange 3 of the flexible 2 until one of the edges 9, 10 delimiting the bead 8 comes in contact with an internal surface of the frustoconical wall of the emerging part of the flange 3 of the hose 2. The collar 4 is in the form of a ring delimited by two edges 12, 13 so that the cross section of said ring is maximum at its central circumference and gradually decreases on either side of said central circumference. This ring 4 covers the bead 8 of the motor flange 7, and the frustoconical wall 6 of the flange 3 of the hose 2, a tightening of said collar 4 pressing said frustoconical wall 6 against one of the edges 9, 10 delimiting said bead 8.
En se référant aux figures 3 et 6, le dispositif de protection 5 est composé d'un boîtier comprenant deux parties articulées 15, 16 autour d'un axe de rotation 17 et un pion de centrage 18. Les deux parties 15, 16 sont identiques et comportent chacune un corps creux hémicylindrique 19 prolongé par une demi tête 20 creuse de forme tronconique. Les deux parties 15, 16 sont en continuité et sont reliées l'une à l'autre au moyen de l'axe de rotation 17 pouvant par exemple être constitué par une bande de matériau de moindre épaisseur et apte à se plier pour rapprocher ou éloigner ces deux parties 15, 16. Avantageusement, les deux parties 15, 16 et l'axe de rotation 18 sont réalisés dans le même matériau.  Referring to Figures 3 and 6, the protection device 5 is composed of a housing comprising two articulated parts 15, 16 around an axis of rotation 17 and a centering pin 18. The two parts 15, 16 are identical and each comprise a semi-cylindrical hollow body 19 extended by a hollow half-head 20 of frustoconical shape. The two parts 15, 16 are in continuity and are connected to each other by means of the axis of rotation 17 which may for example be constituted by a strip of material of lesser thickness and able to bend to bring closer or farther these two parts 15, 16. Advantageously, the two parts 15, 16 and the axis of rotation 18 are made of the same material.
En se référant aux figures 3, 5A et 5B, le pion de centrage 18 comporte un corps cylindrique creux allongé 21 et une collerette 22 plane et annulaire, dont le plan est perpendiculaire à un axe longitudinal dudit corps allongé 21. Le corps cylindrique creux 21 présente une première extrémité au niveau de laquelle est située la collerette 22 et une deuxième extrémité libre se terminant par un tronçon cylindrique creux 23 de diamètre réduit par rapport au diamètre du reste dudit corps 21, cette différence de diamètre induisant un épaulement 30. L'axe de rotation 17 situé entre les deux parties articulées 15, 16 est solidarisé au pion de centrage 18 au niveau d'une zone centrale de la collerette 22. Préférentiellement, le pion de centrage 18, les deux parties articulées 15, 16 et l'axe de rotation 17 sont réalisés dans le même matériau. Les deux parties 15, 16 sont aptes à passer d'une position d'ouverture, comme cela est illustré aux figures 3, 4A, et 4B à une position de fermeture, comme illustré aux figures 6 et 7, pour laquelle lesdites deux parties 15, 16 sont rabattues l'une contre l'autre au moyen d'un pivotement dans le sens matérialisé par les deux flèches 24, 25 de la figure 6. Dans la position fermée, les deux parties 15, 16 sont complémentaires pour constituer une pièce creuse ayant la forme d'un champignon, doté d'un corps cylindrique de diamètre constant, prolongé par une tête cylindrique élargie 27 ayant un diamètre variable et supérieur à celui dudit corps 26. Une fois que les deux parties 15, 16 ont été rabattues l'une contre l'autre, elles sont fixées l'une à l'autre par des clips 28, 29 en plastique. Le flexible 2 présente une collerette arrière 40 sur laquelle viennent en butée les extrémités libres des deux parties 15, 16 articulées, afin d'empêcher un coulissement du dispositif de protection le long du flexible 2. Il est à noter que la tête élargie cylindrique 27 est dimensionnée de telle sorte qu'il existe un jeu entre ladite partie 27 et le collier de serrage 4 monté sur l'extrémité élargie 3 du flexible 2. Referring to Figures 3, 5A and 5B, the centering pin 18 comprises an elongated hollow cylindrical body 21 and a flat and annular flange 22, the plane of which is perpendicular to a longitudinal axis of said elongated body 21. The hollow cylindrical body 21 has a first end at which the flange 22 is located and a second free end ending in a hollow cylindrical section 23 of reduced diameter compared to the diameter of the rest of said body 21, this difference in diameter inducing a shoulder 30. The axis of rotation 17 located between the two articulated parts 15, 16 is secured to the centering pin 18 at a zone central flange 22. Preferably, the centering pin 18, the two articulated parts 15, 16 and the axis of rotation 17 are made of the same material. The two parts 15, 16 are capable of passing from an open position, as illustrated in FIGS. 3, 4A, and 4B to a closed position, as illustrated in FIGS. 6 and 7, for which said two parts 15 , 16 are folded against each other by means of a pivoting in the direction materialized by the two arrows 24, 25 of FIG. 6. In the closed position, the two parts 15, 16 are complementary to constitute a part hollow in the shape of a mushroom, provided with a cylindrical body of constant diameter, extended by an enlarged cylindrical head 27 having a variable diameter and greater than that of said body 26. Once the two parts 15, 16 have been folded down one against the other, they are fixed to each other by plastic clips 28, 29. The hose 2 has a rear flange 40 on which the free ends of the two articulated parts 15, 16 come into abutment, in order to prevent sliding of the protection device along the hose 2. It should be noted that the enlarged cylindrical head 27 is dimensioned so that there is play between said part 27 and the clamp 4 mounted on the enlarged end 3 of the hose 2.
Un procédé de mise en place du dispositif de protection 5 sur l'ensemble constitué par le flexible 2, l'extrémité évasée 3 et le collier de serrage 4, suit les étapes suivantes,  A method of fitting the protection device 5 onto the assembly constituted by the flexible 2, the flared end 3 and the clamp 4, follows the following steps,
- Une étape de positionnement du dispositif de protection 5 devant cet ensemble de sorte que le pion de centrage 18 soit placé en face de l'extrémité évasée 3, comme illustré à la figure 4A, les deux parties 15, 16 étant dans une position d'ouverture,  - A step of positioning the protection device 5 in front of this assembly so that the centering pin 18 is placed opposite the flared end 3, as illustrated in FIG. 4A, the two parts 15, 16 being in a position d 'opening,

De cette manière, la tête élargie 27 du dispositif de protection 5 enveloppe le collier de serrage 4 et l'extrémité évasée 3, en laissant subsister un jeu avec ledit collier 4, et le corps cylindrique 26 dudit dispositif de protection 5 enveloppe le flexible 2. La collerette 22 du pion de centrage 18 sert d'élément d'appui aux deux parties 15, 16 lorsqu'elles sont dans une position de fermeture, - A step of continuing said insertion until the shoulder 30 of the centering pin 18 comes into abutment against an internal shoulder of the flared end 3, this abutment keeping the flange 22 at a certain distance from the collar tightening 4, - A step of folding the two parts 15, 16 towards each other by means of a pivoting around the axis of rotation 17, so that said parts 15, 16 come into contact with one of the other, by wrapping the clamp 4, the flared end 3 and the hose 2. In this way, the enlarged head 27 of the protective device 5 wraps the clamp 4 and the flared end 3, leaving a clearance with said collar 4, and the cylindrical body 26 of said protection device 5 envelops the hose 2. The collar 22 of the centering pin 18 serves as a support element for the two parts 15, 16 when they are in a position of closing,
- Une étape de fixation des deux parties 15, 16 l'une à l'autre au moyen des clips 28, 29 en plastique. II est à noter que le dispositif de protection 5 est monté temporairement sur le flexible 2, le temps d'acheminer celui-ci sur les lieux de son montage sur un véhicule. Une fois l'assemblage « flexible/dispositif de protection » acheminé au bon endroit, le dispositif de protection est ensuite retiré tout aussi facilement et rapidement que ne l'a été son montage autour dudit flexible 2.  - A step of fixing the two parts 15, 16 to each other by means of plastic clips 28, 29. It should be noted that the protection device 5 is temporarily mounted on the hose 2, the time to convey the latter to the places of its mounting on a vehicle. Once the “flexible / protective device” assembly is routed to the right place, the protective device is then removed just as easily and quickly as it was mounted around said flexible hose 2.
