Description

"Bouchon de fermeture d'un carter de cylindres" "Closing cap of a cylinder block"

L'invention concerne un bouchon de fermeture pour un carter de cylindres, la disposition d'un tel bouchon de fermeture dans un carter de cylindres ainsi qu'un carter de cylindres pourvu d'un tel bouchon de fermeture.The invention relates to a closure cap for a cylinder block, the provision of such a closure cap in a cylinder block and a cylinder block provided with such a closure cap.

Lors de la fabrication d'un carter de cylindres d'un moteur à combustion interne, des trous sont générés dans la paroi du carter. Une partie des trous est générée par le passage de broches destinées à former des canaux d'huile dans le carter, - et d'autres trous sont générés pour former des évents.- Ces trous doivent être obturés afin de garantir l'étanchéité à l'huile du carter.In the manufacture of a crankcase of an internal combustion engine, holes are generated in the crankcase wall. Part of the holes are generated by the passage of pins for forming oil channels in the housing, and other holes are generated to form vents. These holes must be closed to ensure watertightness. crankcase oil.

Une première possibilité d'obturation consiste en l'utilisation de bouchons vissés. Une autre possibilité est celle d'emmancher des billes dans les obturations et de les coller.A first shutter option is the use of screw caps. Another possibility is to put beads in the fillings and paste them.

Dans un cas comme dans l'autre, les bouchons constituent des éléments ayant une épaisseur assez importante, par exemple de l'ordre de 10 mm.In one case as in the other, the plugs are elements having a fairly large thickness, for example of the order of 10 mm.

Une telle épaisseur du bouchon entraîne une profondeur d'implantation également assez importante. Il s'y ajoute un jeu fonctionnel nécessaire entre la paroi et des éléments accessoires remplissant plusieurs rôles dans le fonctionnement du moteur. A titre d'exemple, il est cité le jeu entre la paroi et l'ensemble chaîne de distribution qui est supérieur à 3 mm, ou le jeu entre la paroi et la poulie amortisseur de la chaîne de distribution qui est de l'ordre de 2 mm, ou encore le jeu entre la paroi et le bras tendeur de la courroie d'accessoire qui est de l'ordre de 3 mm.Such a thickness of the cap results in a depth of implantation also quite important. There is a necessary functional clearance between the wall and accessory elements fulfilling several roles in the operation of the engine. By way of example, mention is made of the clearance between the wall and the distribution chain assembly which is greater than 3 mm, or the clearance between the wall and the damping pulley of the distribution chain which is of the order of 2 mm, or the clearance between the wall and the tension arm of the accessory belt which is of the order of 3 mm.

Il en résulte que les moyens d'obturation utilisés jusqu'à maintenant entraînent des contraintes de conception, qui ne sont pas toujours acceptables.As a result, the sealing means used up to now lead to design constraints, which are not always acceptable.

Aussi, le but de l'invention est de proposer des moyens d'obturation des trous pratiqués dans un carter de cylindres qui remédient aux inconvénients décrits ci avant .Also, the object of the invention is to provide means for closing the holes in a crankcase. cylinders that remedy the disadvantages described above.

Le but de 1 ' invention est atteint avec un bouchon de fermeture destiné à obturer un trou pratiqué dans un carter de cylindres, qui est constitué par un disque de faible épaisseur.The object of the invention is achieved with a closure plug for closing a hole in a cylinder housing, which is constituted by a thin disc.

Avantageusement, le disque est pourvu d'un chanfrein d'entrée.Advantageously, the disk is provided with an input chamfer.

La réalisation d'un tel bouchon permet d'obturer les trous pratiqués dans un carter de cylindres de manière à éviter des surépaisseurs ou des pièces en saillie par rapport à la paroi du carter.The production of such a cap makes it possible to close off the holes made in a cylinder casing so as to avoid oversize or protruding parts with respect to the wall of the casing.

L'absence de pièces proéminentes ou de parties en saillie permet d'obtenir le jeu fonctionnel nécessaire entre la paroi du carter du cylindre et d'autres constituants du moteur à combustion interne sans entraver 1 ' étanchéité à l'huile du carter.The absence of protruding parts or projecting parts makes it possible to obtain the necessary functional clearance between the wall of the cylinder housing and other constituents of the internal combustion engine without hindering the oil seal of the housing.

Cette disposition de l'invention permet d'obtenir une obturation pour le moins aussi fiable que par l'utilisation d'un bouchon vissé ou d'une bille emmanchée, ou encore d'autres moyens utilisés avant 1 ' invention.This arrangement of the invention provides a closure at least as reliable as the use of a screw cap or a ball fitted, or other means used before the invention.

Le bouchon de fermeture de l'invention permet d'obtenir une obturation fiable d'un trou pratiqué dans un carter de cylindres rien que par sa forme qui est celle d'un simple disque pourvu d'un chanfrein d'entrée, et qui permet ainsi d'emmancher le bouchon dans le trou du carter avec un ajustement serré.The closure cap of the invention makes it possible to obtain a reliable closure of a hole made in a cylinder casing only by its shape which is that of a simple disk provided with an entry chamfer, and which allows thus to fit the plug in the housing hole with a tight fit.

En variante, un chanfrein d'entrée est réalisé sur l'alésage du carter de cylindres et/ou une gorge est pratiquée en fond d'alésage.Alternatively, an inlet chamfer is made on the bore of the cylinder block and / or a groove is formed at the bottom of the bore.

L'étanchéité entre le bouchon de l'invention et le carter de cylindres peut être améliorée en disposant, lors de la mise en place du bouchon dans le trou, un produit d'étanchéité sur le pourtour intérieur du trou. En garnissant le logement que représente le trou pour le bouchon à mettre en place, de la manière indiquée, on assure aussi la fonction maintien du bouchon dans le trou par collage. Lors de l'emmanchement du bouchon dans le trou, le produit d'êtanchéitê vient se loger, pour le moins principalement, entre le chanfrein du bouchon et l'épaulement de l'alésage ou dans la gorge. Cette disposition garantit ainsi l'étanchéité de l'obturation.The seal between the plug of the invention and the cylinder casing can be improved by providing, during the introduction of the plug in the hole, a sealant on the inner periphery of the hole. By filling the housing that represents the hole for the cap to put in place, as indicated, we also ensures the function of holding the plug in the hole by gluing. When fitting the stopper into the hole, the sealing product is housed, at least mainly, between the chamfer of the stopper and the shoulder of the bore or in the groove. This arrangement thus ensures the sealing of the closure.

Le bouchon de 1 ' invention présente 1 ' avantage de pouvoir être utilisé dans des encombrements réduits. De plus, le bouchon de l'invention est, notamment grâce à sa forme simple, une pièce que l'on peut réaliser de manière simple et de manière peu coûteuse. Il contribue en plus à la réalisation de moteurs compacts ou, pour le moins, évite que les moteurs deviennent moins compacts.The plug of the invention has the advantage of being able to be used in reduced dimensions. In addition, the plug of the invention is, thanks to its simple shape, a piece that can be made simply and inexpensively. It also contributes to the production of compact engines or, at the very least, prevents engines from becoming less compact.

Le but de l'invention est également atteint avec une disposition d'un bouchon de fermeture décrit ci avant en position d'obturation d'un trou pratiqué dans un carter de cylindres, ainsi que par un carter de cylindres comprenant un bouchon de fermeture selon la description ci avant .The object of the invention is also achieved with an arrangement of a closure cap described above in the closed position of a hole made in a cylinder block, as well as by a cylinder block comprising a closure cap according to the description above.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description ci- après d'un mode de réalisation préféré de l'invention. Cette description est faite en référence aux dessins dans lesquels : la figure 1 représente un bouchon de l'invention en une vue en perspective ; la figure 2 représente le bouchon de l'invention, en une vue latérale, dans une position juste avant l'emmanchement dans un trou pratiqué dans un carter de cylindres, la figure 3 schématise, en un détail de la figure 2, la mise en place du bouchon de l'invention dans un trou, et la figure 4 montre la disposition de deux trous à boucher sur un carter de cylindres d'un moteur à combustion interne. Un bouchon 1 destiné à obturer un trou 2 pratiqué dans un carter de cylindres C, est constitué par un disque 3 présentant un diamètre d et une épaisseur e. Le diamètre d du disque 3 est déterminé de manière à permettre 1 ' introduction du bouchon 1 dans le trou 2 avec un ajustement serré.Other features and advantages of the present invention will become apparent from the following description of a preferred embodiment of the invention. This description is made with reference to the drawings in which: FIG. 1 shows a plug of the invention in a perspective view; FIG. 2 shows the plug of the invention, in a lateral view, in a position just before fitting into a hole made in a cylinder block, FIG. 3 diagrammatically shows in a detail of FIG. place the plug of the invention in a hole, and Figure 4 shows the arrangement of two holes to be plugged on a cylinder block of an internal combustion engine. A plug 1 for closing a hole 2 formed in a cylinder casing C is constituted by a disk 3 having a diameter d and a thickness e. The diameter of the disk 3 is determined so as to allow the plug 1 to be inserted into the hole 2 with a tight fit.

L'épaisseur e du disque 3 est comprise entre 3 mm et 4 mm. Cette épaisseur correspond à environ 10 % du diamètre du disque 3.The thickness e of the disc 3 is between 3 mm and 4 mm. This thickness corresponds to approximately 10% of the diameter of the disc 3.

Pour s'affranchir des différences de dilatation entre différents matériaux, le bouchon 1 est réalisé dans la même matière que le carter C dans lequel le trou à obturer est pratiqué. Ainsi, pour un carter en alliage d'aluminium, le bouchon est également réalisé en alliage d'aluminium. Dans la mesure possible, le bouchon est réalisé dans le même alliage d'aluminium que le carter.To overcome the differences in expansion between different materials, the plug 1 is made of the same material as the casing C in which the hole to be closed is practiced. Thus, for an aluminum alloy casing, the cap is also made of aluminum alloy. As far as possible, the plug is made of the same aluminum alloy as the housing.

Le fait de choisir le diamètre du bouchon 1, ou du disque 3, de manière que le bouchon 1 soit introduit dans le trou 2 du carter C avec un ajustement serré, assure déjà à lui seul une bonne étanchéité à l'huile. Le coefficient de serrage, c'est-à-dire le rapport entre la différence entre les deux diamètres, respectivement du disque 3 et du trou 2, et le diamètre du trou 2 peut varier selon la pression d'huile maximale estimée pour un type de moteur donné. Il est en général de l'ordre de 0, 05.The fact of choosing the diameter of the plug 1, or the disc 3, so that the plug 1 is introduced into the hole 2 of the casing C with a tight fit, already ensures alone a good oil seal. The clamping coefficient, that is to say the ratio between the difference between the two diameters, respectively of the disc 3 and the hole 2, and the diameter of the hole 2 may vary according to the maximum oil pressure estimated for a type given engine. It is generally of the order of 0.05.

Pour améliorer cette étanchéité encore d'avantage, et pour assurer une fonction de maintien par collage, un produit d'étanchéité, par exemple du LOCTITE® 129078, est déposé dans le logement constituant le trou 2 et destiné à recevoir le bouchon 1. Lors de l'emmanchement, le produit d'étanchéité est repoussé dans le chanfrein d'entrée, comme cela est représenté sur la figure 3. Plus particulièrement, le produit d'étanchéité vient se loger, au moins principalement, entre le chanfrein du bouchon et l'épaulement de l'alésage et garantit ainsi 1 'étanchéité. To improve this seal even more advantageously, and to ensure a function of holding by gluing, a sealant, for example LOCTITE ® 129078, is deposited in the housing constituting the hole 2 and intended to receive the plug 1. When of the fitting, the sealant is pushed into the chamfer input, as shown in Figure 3. More particularly, the sealant is housed, at least primarily between the chamfer of the cap and the shoulder of the bore and thus ensures 1 sealing.
