The present invention claims the priority of French application No. 2110764 filed on 12.10.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
La présente invention concerne l’assemblage mécanique, en particulier le détrompage au montage d’un tuyau. The present invention relates to mechanical assembly, in particular keying when mounting a pipe.
Le montage d’un tuyau ayant à chaque extrémité un connecteur identique peut conduire un opérateur à inverser par erreur le branchement, ce qui peut conduire à une détérioration du tuyau. Fitting a hose with an identical connector at each end can lead an operator to invert the connection by mistake, which can lead to damage to the hose.
Une solution connue est de faire un marquage spécifique visant à indiquer le sens du montage. Cependant ce marquage peut être illisible ou peu visible au moment du montage. A known solution is to make a specific marking to indicate the direction of assembly. However, this marking may be illegible or barely visible at the time of assembly.

-un tuyau comprenant à une première extrémité un troisième connecteur, à une seconde extrémité un quatrième connecteur, le troisième et quatrième connecteur étant complémentaires respectivement aux premier et second connecteur et aptes à être raccordés à ce premier et second connecteur pour former un premier et second raccord fluidique, caractérisé en ce que le tuyau comprend, en partant de sa première extrémité, un premier coude et en ce que l’élément comprend une butée dont la position sur l’élément et la dimension sont configurées de sorte que si le troisième connecteur de la première extrémité est présenté au montage devant le second connecteur, la butée vient au contact du tuyau après le coude, empêchant la connexion du troisième connecteur avec le second connecteur. -a pipe comprising at a first end a third connector, at a second end a fourth connector, the third and fourth connector being respectively complementary to the first and second connector and adapted to be connected to this first and second connector to form a first and second fluid connection, characterized in that the pipe comprises, starting from its first end, a first elbow and in that the element comprises an abutment whose position on the element and the dimension are configured so that if the third connector of the first end is presented for assembly in front of the second connector, the abutment comes into contact with the pipe after the elbow, preventing the connection of the third connector with the second connector.
L’effet technique est d’éviter une erreur de montage. The technical effect is to avoid an assembly error.
Diverses caractéristiques supplémentaires peuvent être prévues, seules ou en combinaisons Selon une réalisation, le tuyau comprend en partant de sa seconde extrémité un second coude, la longueur du tuyau entre la première extrémité et le premier coude étant inférieure à la longueur du tuyau entre la seconde extrémité et le second coude, la butée ayant une longueur comprise entre les deux longueurs précitées. Various additional features may be provided, singly or in combinations According to one embodiment, the pipe comprises, starting from its second end, a second elbow, the length of the pipe between the first end and the first elbow being less than the length of the pipe between the second end and the second elbow, the stop having a length between the two aforementioned lengths.
Selon une réalisation, les deux raccords fluidiques sont des raccords rapides de type raccords encliquetables. According to one embodiment, the two fluidic connectors are quick connectors of the snap-in connector type.
Selon une réalisation, le premier et le second connecteur de l’élément sont des connecteurs mâles. According to one embodiment, the first and the second connector of the element are male connectors.
Selon une réalisation, l’élément comprend une première pièce comprenant le premier connecteur et une seconde pièce distincte de la première pièce comprenant le second connecteur. According to one embodiment, the element comprises a first part comprising the first connector and a second part distinct from the first part comprising the second connector.
Selon une réalisation, la butée présente une forme de paroi mince. According to one embodiment, the abutment has the shape of a thin wall.
Selon une réalisation, la paroi de la butée est prolongée par deux parois en regard de sorte à former un II de protection du second raccord fluidique. According to one embodiment, the wall of the abutment is extended by two facing walls so as to form an II for protecting the second fluid connection.
L’invention a aussi pour objet un moteur à combustion interne comprenant un ensemble selon l’une quelconque des variantes précédemment décrites. The invention also relates to an internal combustion engine comprising an assembly according to any one of the previously described variants.
Selon une réalisation, la première pièce est un filtre à air, la seconde pièce un carter moteur, le tuyau étant un tuyau de récupération des gaz du carter moteur et de retour vers le filtre à air. According to one embodiment, the first part is an air filter, the second part a crankcase, the pipe being a pipe for recovering the gases from the crankcase and returning to the air filter.
L’invention a aussi pour objet un véhicule automobile, caractérisé en ce qu’il comprend un moteur à combustion interne selon l’une des variantes précédemment décrites. The invention also relates to a motor vehicle, characterized in that it comprises an internal combustion engine according to one of the previously described variants.
D’autres particularités et avantages apparaîtront à la lecture de la description ci-après d’un mode particulier de réalisation, non limitatif de l’invention, faite en référence aux figures dans lesquelles : Other features and advantages will appear on reading the description below of a particular, non-limiting embodiment of the invention, made with reference to the figures in which:
[Fig 1] : cette figure représente partiellement un mode de réalisation d’un ensemble conforme à l’invention. [Fig 2] : cette figure représente le tuyau sous deux angles de vue différents. [Fig 1]: this figure partially represents an embodiment of an assembly according to the invention. [Fig 2]: this figure shows the pipe from two different angles.
[Fig 3] : cette figure représente, selon la coupe AA indiquée en figure 1, la connexion de l’extrémité du tuyau au connecteur du filtre à air. [Fig 3]: this figure shows, according to section AA indicated in figure 1, the connection of the end of the pipe to the connector of the air filter.
La figure 1 représente un filtre à air FA. A ce filtre à air FA est connecté un tuyau T. Ce tuyau est également connecté à un carter, non représenté. Le filtre à air FA et le carter peuvent appartenir à un moteur à combustion interne. Un tel moteur à combustion interne peut équiper un véhicule automobile, pour sa propulsion. Figure 1 shows an FA air filter. To this air filter FA is connected a pipe T. This pipe is also connected to a casing, not shown. The air filter FA and the crankcase can belong to an internal combustion engine. Such an internal combustion engine can equip a motor vehicle, for its propulsion.
Le carter comprend un premier connecteur M1 et le filtre à air FA comprend un second connecteur M2. Le connecteur du carter et celui M2 du filtre à air FA sont identiques. Dans ce mode de réalisation le connecteur du carter et celui M2 du filtre à air FA sont des connecteurs males, ce qui avantage la conception du carter du filtre à air FA. Le connecteur du carter et celui M2 du filtre à air FA pourraient être des connecteurs femelles, mais cela serait moins avantageux. The housing includes a first connector M1 and the air filter FA includes a second connector M2. The crankcase connector and that M2 of the FA air filter are identical. In this embodiment, the housing connector and that M2 of the air filter FA are male connectors, which benefits the design of the housing of the air filter FA. The crankcase connector and that M2 of the FA air filter could be female connectors, but this would be less advantageous.
Comme le montre également la figure 3, le tuyau T comprend à une première extrémité E1 un troisième connecteur F1 et à une seconde extrémité E2 un quatrième connecteur F2. As also shown in Figure 3, the pipe T comprises at a first end E1 a third connector F1 and at a second end E2 a fourth connector F2.
Ce troisième et quatrième connecteur, F1 , F2, sont des connecteurs complémentaires respectivement aux premier et second connecteur M1 , M2. Dans ce mode de réalisation, le troisième et quatrième connecteur, F1 , F2, sont donc des connecteurs femelles aptes à être raccordés au premier et second connecteur M1 , M2, pour former un premier et second raccord fluidique. This third and fourth connector, F1, F2, are complementary connectors respectively to the first and second connector M1, M2. In this embodiment, the third and fourth connectors, F1, F2, are therefore female connectors capable of being connected to the first and second connectors M1, M2, to form a first and second fluid connection.
Pour des raisons de rapidité de montage, les deux raccords fluidiques sont des raccords rapides de type raccord encliquetables. For reasons of speed of assembly, the two fluidic connectors are quick connectors of the snap-in connector type.
Le tuyau T est ici un tuyau de récupération des gaz du carter moteur et de retour vers le filtre à air FA. The pipe T here is a pipe for recovering the gases from the crankcase and returning to the air filter FA.
Comme le montre la figure 2, le tuyau T comprend, en partant de sa première extrémité E1 et en suivant le tuyau, un premier coude C1. Le tuyau T comprend encore, en partant de sa seconde extrémité E2 et en suivant le tuyau, un second coude C2. La longueur L1 du tuyau T entre la première extrémité E1 et le premier coude C1 est inférieure à la longueur L2 du tuyau T entre la seconde extrémité E2 et le second coude C2. Afin qu’un opérateur évite de se tromper au montage du tuyau T sur le filtre à air FA, il est disposé sur le filtre à air FA une butée B dont les dimensions et la position sont prévues de sorte qu’au montage, si le troisième connecteur F1 de la première extrémité E1 est présenté devant le second connecteur M2, la butée B vient au contact du tuyau T après le coude C1 , empêchant ainsi la connexion du troisième connecteur F1 avec le second connecteur M2. As shown in Figure 2, the pipe T comprises, starting from its first end E1 and following the pipe, a first elbow C1. The pipe T further comprises, starting from its second end E2 and following the pipe, a second elbow C2. The length L1 of the pipe T between the first end E1 and the first elbow C1 is less than the length L2 of the pipe T between the second end E2 and the second elbow C2. In order for an operator to avoid making a mistake when fitting the pipe T on the air filter FA, there is placed on the air filter FA a stop B whose dimensions and position are provided so that during fitting, if the third connector F1 of the first end E1 is presented in front of the second connector M2, the stop B comes into contact with the pipe T after the elbow C1, thus preventing the connection of the third connector F1 with the second connector M2.
Les dimensions de la butée sont prévues de sorte que la butée B ne vient pas au contact tuyau T si le montage est correct, c’est-à-dire si le quatrième connecteur F2 est présenté devant le second connecteur M2. La longueur L de la butée B est donc comprise en la longueur L1 et la longueur L2. The dimensions of the stop are provided so that the stop B does not come into contact with pipe T if the assembly is correct, i.e. if the fourth connector F2 is presented in front of the second connector M2. The length L of the stop B is therefore included in the length L1 and the length L2.
Comme le montre les figures 1 et 2 la butée B présente la forme d’une paroi B1 mince, par exemple une nervure dont le bord libre fait office de butée. Ainsi, si l’opérateur tente de monter le tuyau T à l’envers, la nervure va bloquer le tuyau T et empêcher montage. La forme de paroi permet également une protection du raccord fluidique connecté au filtre à air FA. As shown in Figures 1 and 2, the stop B has the shape of a thin wall B1, for example a rib whose free edge acts as a stop. Thus, if the operator tries to mount the T-pipe upside down, the rib will block the T-pipe and prevent assembly. The shape of the wall also allows protection of the fluid connection connected to the air filter FA.
Pour améliorer la protection du raccord fluidique connecté au filtre à air FA, on peut prévoir de prolonger chaque côté de la paroi B1 de la butée B par deux parois B2, B3 en regard, ici perpendiculaires à la paroi B1 de la butée B, les trois parois B1 , B2, B3 formant un U de protection du raccord fluidique connecté au filtre à air FA. To improve the protection of the fluid connection connected to the air filter FA, it is possible to extend each side of the wall B1 of the stop B by two facing walls B2, B3, here perpendicular to the wall B1 of the stop B, the three walls B1, B2, B3 forming a U for protecting the fluid connection connected to the air filter FA.
L’invention ne se limite pas au mode de réalisation décrit. En variante, les connecteurs du filtre à air et du carter du moteur peuvent être sur d’autres pièces distinctes ou appartenir à une même pièce d’un ensemble mécanique. Dans une autre variante, le tuyau peut un autre tuyau qu’un tuyau de réaspiration des gaz de carter moteur. Dans une autre variante, les deux coudes peuvent être confondus, autrement dit le tuyau ne possède qu’un coude. The invention is not limited to the embodiment described. Alternatively, the air filter and motor housing connectors may be on other separate parts or belong to the same part of a mechanical assembly. In another variant, the pipe may be a pipe other than a crankcase gas rebreathing pipe. In another variant, the two elbows can be confused, in other words the pipe has only one elbow.
L’invention permet d’éviter une erreur de montage, avec peu de modification, donc un coût de réalisation très faible. Permet d’éviter la solution alternative d’un marquage spécifique visant à indiquer le sens du montage, ce marquage pouvant être illisible ou peu visible au moment du montage. The invention makes it possible to avoid an assembly error, with little modification, therefore a very low production cost. Allows to avoid the alternative solution of a specific marking aiming at indicating the direction of the assembly, this marking being able to be illegible or not very visible at the time of the assembly.
