JOINT DE CULASSE COMPRENANT UN STOPPEUR BORD A BORD

Figure img00010001

La présente invention se rapporte à un joint, notamment un joint de culasse, comprenant un stoppeur bord à bord. La présente invention est plus particulièrement adaptée au joint de culasse multifeuilles comprenant au moins deux tôles dont au moins une est nervurée. CYLINDER HEAD GASKET COMPRISING AN EDGE-TO-EDGE STOPPER
Figure img00010001

The present invention relates to a seal, in particular a cylinder head gasket, comprising an edge to edge stopper. The present invention is more particularly suited to the multi-sheet cylinder head gasket comprising at least two sheets, at least one of which is ribbed.

Un joint de culasse comprend généralement deux tôles avec au moins une ouverture correspondant à l'ouverture d'une chambre de combustion, au moins l'une des deux tôles, et de préférence les deux, comportant une nervure ménagée autour de chaque ouverture, à distance du bord de ladite l'ouverture, lesdites nervures étant déformées vers l'intérieur du joint. A cylinder head gasket generally comprises two sheets with at least one opening corresponding to the opening of a combustion chamber, at least one of the two sheets, and preferably both, having a rib formed around each opening, with distance from the edge of said opening, said ribs being deformed towards the inside of the joint.

En complément, le joint comprend une tôle support intermédiaire interposée entre les deux tôles extérieures, au droit des nervures, ainsi qu'un stoppeur, sous forme d'une cale annulaire, ayant un diamètre intérieur correspondant sensiblement à celui de l'ouverture et un diamètre extérieur inférieur à celui des nervures, ledit stoppeur étant disposé bord à bord, dans le prolongement de la tôle support. In addition, the seal includes an intermediate support sheet interposed between the two outer sheets, in line with the ribs, as well as a stopper, in the form of an annular shim, having an internal diameter corresponding substantially to that of the opening and a outer diameter less than that of the ribs, said stopper being arranged edge to edge, in the extension of the support sheet.

Selon l'art antérieur, une partie au moins de la tôle support est toujours intercalée entre les nervures. Les tôles sont des produits laminés dont l'épaisseur et les tolérances dimensionnelles sont imposées par leur fabrication et sont peu précises. Or, pour assurer un bon fonctionnement du joint de culasse, il est important de maîtriser avec une grande précision l'écartement des nervures lorsque ces dernières sont en contact avec l'élément interposé. According to the prior art, at least part of the support sheet is always interposed between the ribs. Sheets are rolled products whose thickness and dimensional tolerances are imposed by their manufacture and are not very precise. However, to ensure proper operation of the cylinder head gasket, it is important to control with great precision the spacing of the ribs when the latter are in contact with the interposed element.

Aussi, la présente invention vise à pallier les inconvénients de l'art antérieur en proposant un nouveau joint de culasse comprenant un stoppeur Also, the present invention aims to overcome the drawbacks of the prior art by proposing a new cylinder head gasket comprising a stopper

bord à bord, permettant une meilleure maîtrise de l'écartement des nervures des tôles extérieures.  edge to edge, allowing better control of the spacing of the ribs of the outer sheets.

A cet effet, t'invention a pour objet un joint de culasse avec au moins une ouverture correspondant à une chambre de combustion, comprenant d'une part, au moins une tôle extérieure, au moins l'une d'elles comportant une nervure circulaire, entourant l'ouverture, ménagée à distance du bord de ladite ouverture, et d'autre part, une tôle support disposée contre la face nervurée de la ou des tôle (s) extérieure (s), comprenant une ouverture de diamètre supérieure à l'ouverture de la ou des tôle (s) extérieure (s) afin de définir un espace dans lequel est disposé un stoppeur sous forme d'une cale annulaire de diamètre intérieur correspondant sensiblement à celui de l'ouverture et de diamètre extérieur sensiblement ajusté à l'ouverture de la tôle support de manière à être disposé bord à bord, caractérisé en ce que le stoppeur a un diamètre extérieur supérieur à celui de la ou des nervures.  To this end, the invention relates to a cylinder head gasket with at least one opening corresponding to a combustion chamber, comprising on the one hand, at least one external sheet, at least one of them comprising a circular rib , surrounding the opening, formed at a distance from the edge of said opening, and on the other hand, a support sheet disposed against the ribbed face of the outer sheet (s), comprising an opening of diameter greater than l opening of the outer sheet (s) in order to define a space in which a stopper is arranged in the form of an annular shim with an inner diameter corresponding substantially to that of the opening and with an outer diameter substantially adjusted to the opening of the support sheet so as to be arranged edge to edge, characterized in that the stopper has an outside diameter greater than that of the rib or ribs.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre du dispositif de l'invention, description donnée à titre d'exemple uniquement, en regard des dessins annexés sur lesquels : - la figure 1 est une vue en coupe longitudinale d'un joint de culasse selon l'invention, - la figure 2 est une vue en coupe dans le plan de la tôle support, et - la figure 3 est une vue en coupe longitudinale d'une variante de réalisation du joint de culasse de l'invention.  Other characteristics and advantages will emerge from the description which follows of the device of the invention, description given by way of example only, with reference to the appended drawings in which: - Figure 1 is a view in longitudinal section of a cylinder head gasket according to the invention, - Figure 2 is a sectional view in the plane of the support plate, and - Figure 3 is a longitudinal sectional view of an alternative embodiment of the cylinder head gasket of the invention .

Sur les figures, on a représenté un joint de culasse 10 comprenant au moins une tôles extérieures 12, de préférence deux, avec au moins une ouverture 14 correspondant à une chambre à combustion d'un bloc moteur, au moins l'une des tôles extérieures 12, et de préférence les deux, comportant une nervure 16 circulaire, entourant l'ouverture 14, ménagée à une distance d du bord de l'ouverture 14, la ou les nervures étant déformée (s) vers l'intérieur du joint.  In the figures, there is shown a cylinder head gasket 10 comprising at least one external plate 12, preferably two, with at least one opening 14 corresponding to a combustion chamber of an engine block, at least one of the external plates 12, and preferably both, comprising a circular rib 16, surrounding the opening 14, formed at a distance d from the edge of the opening 14, the rib or ribs being deformed towards the interior of the joint.

Les nervures 16 des tôles extérieures peuvent avoir des raideurs différentes, et être centrées l'une par rapport à l'autre ou non, si des efforts différenciés sont souhaités.  The ribs 16 of the outer sheets may have different stiffnesses, and may be centered with respect to each other or not, if differentiated forces are desired.

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

Une tôle support intermédiaire 18 est interposée entre les tôles extérieures 12. Dans le cas, d'un joint avec une seule tôle extérieure, la tôle intermédiaire 18 est disposée contre la face nervurée en saillie de ladite tôle extérieure.  An intermediate support sheet 18 is interposed between the outer sheets 12. In the case of a joint with a single outer sheet, the intermediate sheet 18 is disposed against the rib face projecting from said outer sheet.

La tôle support comprend une ouverture concentrique à l'ouverture 14 des tôles extérieures 12, de diamètre supérieur à l'ouverture 14 afin de définir un espace dans lequel est disposé un stoppeur 20, sous forme d'une cale annulaire, de diamètre intérieur correspondant à celui de l'ouverture 14 et de diamètre extérieur sensiblement ajusté à l'ouverture de la tôle support, de manière à être disposé bord à bord.  The support sheet includes an opening concentric with the opening 14 of the external sheets 12, of diameter greater than the opening 14 in order to define a space in which a stopper 20 is arranged, in the form of an annular shim, of corresponding inside diameter to that of the opening 14 and of external diameter substantially adjusted to the opening of the support sheet, so as to be arranged edge to edge.

Ce stoppeur comprend au moins une zone 22 d'épaisseur X1 supérieure à l'épaisseur X2 de la tôle support afin de constituer un limiteur d'écrasement des nervures, une première barrière d'étanchéité et de permettre la mise en voûte d'au moins une tôle extérieure 12 de manière à limiter les débattements de cette dernière en fonctionnement.  This stopper comprises at least one zone 22 of thickness X1 greater than the thickness X2 of the support sheet in order to constitute a crushing limiter for the ribs, a first sealing barrier and to allow the arching of at least an outer sheet 12 so as to limit the deflections of the latter in operation.

Selon l'invention, le diamètre extérieur du stoppeur 20 est supérieur à celui des nervures 16 si bien qu'une zone 24 dudit stoppeur d'épaisseur inférieur à X1 est intercalée entre les nervures 16, comme illustré par la figure 1.  According to the invention, the outside diameter of the stopper 20 is greater than that of the ribs 16 so that an area 24 of said stopper of thickness less than X1 is interposed between the ribs 16, as illustrated in FIG. 1.

Cette solution a pour avantage d'intercaler entre les nervures 16 une pièce d'une précision relativement importante, le stoppeur obtenu de préférence par estampage, étant parfaitement calibré.  This solution has the advantage of interposing between the ribs 16 a piece of relatively high precision, the stopper preferably obtained by stamping, being perfectly calibrated.

Comme illustré par la figure 2, dans le cas d'un joint de culasse multicylindre, il est possible selon l'agencement de l'invention de réduire la distance intercylindre du fait que seul le stoppeur 20 est disposé entre les ouvertures 14.  As illustrated by FIG. 2, in the case of a multi-cylinder head gasket, it is possible according to the arrangement of the invention to reduce the inter-cylinder distance because only the stopper 20 is disposed between the openings 14.

Le stoppeur 20 peut être de type métallique ou bien en matériau fibreux comme décrit dans la demande de brevet FR-01. 06129 au nom du demandeur.  The stopper 20 can be of metallic type or else of fibrous material as described in patent application FR-01. 06129 in the name of the applicant.

Selon une autre caractéristique, le stoppeur peut avoir un profil évolutif le long de sa périphérie. Ainsi, son épaisseur peut varier afin d'obtenir une pression de contact constante malgré des efforts de serrage localisés.  According to another characteristic, the stopper can have an evolving profile along its periphery. Thus, its thickness can vary in order to obtain a constant contact pressure despite localized clamping forces.

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

Avantageusement, dans le cas d'un joint de culasse monocylindre, au moins une languette est prévue en périphérie du stoppeur de manière à assurer une indexation en rotation.  Advantageously, in the case of a single-cylinder head gasket, at least one tongue is provided on the periphery of the stopper so as to provide indexing in rotation.

Dans le cas d'un stoppeur plan avec une épaisseur constante, il n'est pas nécessaire de prévoir des moyens d'indexation en rotation.  In the case of a flat stopper with a constant thickness, it is not necessary to provide means for indexing in rotation.

Selon les cas, le stoppeur peut avoir un profil symétrique, c'est à dire avoir des faces supérieures et inférieures présentant le même profil, ou non. A titre d'exemple, dans le cas d'un joint comportant une seule tôle extérieure, seule la face du stoppeur orientée vers ladite tôle extérieure comprend un décrochement, l'autre face étant sensiblement plane.  Depending on the case, the stopper may have a symmetrical profile, that is to say have upper and lower faces having the same profile, or not. By way of example, in the case of a seal comprising a single external sheet, only the face of the stopper facing said external sheet comprises a recess, the other face being substantially planar.

Sur la figure 3, on a représenté une variante du joint de culasse de l'invention. Dans ce cas, la tôle intermédiaire 18 est constituée de deux tôles 18.1 et 18. 2 qui peuvent avoir un profil particulier pour accentuer les caractéristiques élastiques de ladite tôle 18.  In Figure 3, a variant of the cylinder head gasket of the invention is shown. In this case, the intermediate sheet 18 consists of two sheets 18.1 and 18. 2 which can have a particular profile to accentuate the elastic characteristics of said sheet 18.

En fonction du mode de réalisation, les tôles extérieures, la tôle intermédiaire et le stoppeur peuvent être réalisés chacun d'une seule épaisseur comme illustré par la figure 1 ou bien obtenus par empilage d'au moins deux tôles.  Depending on the embodiment, the outer sheets, the intermediate sheet and the stopper can each be made of a single thickness as illustrated in FIG. 1 or else obtained by stacking at least two sheets.

Bien entendu, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne le mode de maintien du stoppeur qui peut être fixé de manière rigide à la tôle support par soudage, collage ou analogue, par expansion radiale dudit stoppeur.  Of course, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all variants thereof, in particular as regards the method of holding the stopper which can be rigidly fixed to the support sheet by welding, gluing or the like, by radial expansion of said stopper.

Selon un autre mode de réalisation, le maintien du stoppeur est assuré par un élément interposé entre le stoppeur et la tôle support, tel qu'un rivet comprenant à chaque extrémité un rebord rabattu contre les faces du stoppeur et de la tôle support afin de les enserrer et de limiter leurs mouvements relatifs.  According to another embodiment, the retention of the stopper is ensured by an element interposed between the stopper and the support plate, such as a rivet comprising at each end a flange folded against the faces of the stopper and of the support plate in order to enclose and limit their relative movements.

Enfin, le maintien du stoppeur peut être assuré par la tôle support ellemême, cette dernière comportant au niveau de la zone de contact une épaisseur supérieure à celle du stoppeur. Finally, the stopper can be maintained by the support plate itself, the latter comprising at the level of the contact zone a thickness greater than that of the stopper.
