JOINT DE CULASSE COMPRENANT UN STOPPEUR BORD A BORD
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
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.

Selon un mode de réalisation illustré par la figure 1, un joint de culasse 10 comprend deux tôles 12 avec au moins une ouverture 14 correspondant à l'ouverture d'une chambre de combustion, au moins l'une des deux tôles, et de préférence les deux, comportant une nervure 1 6 ménagée autour de chaque ouverture, à distance du bord de ladite l'ouverture, lesdites nervures étant déformées vers l'intérieur du joint.  According to an embodiment illustrated in FIG. 1, a cylinder head gasket 10 comprises two sheets 12 with at least one opening 14 corresponding to the opening of a combustion chamber, at least one of the two sheets, and preferably both, comprising a rib 1 6 formed around each opening, at a distance from the edge of said opening, said ribs being deformed towards the inside of the joint.

En complément, le joint 10 comprend une tôle support 18 intermédiaire interposée entre les deux tôles extérieures 12, au droit des nervures 16, ainsi qu'un stoppeur 20, 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 10 comprises an intermediate support plate 18 interposed between the two external plates 12, in line with the ribs 16, as well as a stopper 20, in the form of an annular wedge, having an internal diameter corresponding substantially to that of the opening and an outside diameter smaller than that of the ribs, said stopper being arranged edge to edge, in the extension of the support sheet.

Ce stoppeur 20 a une 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 20 has a 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 one external sheet 12 of so as to limit the travel of the latter in operation.

Bien que le stoppeur soit normalement immobilisé dans le sens transversal par la tôle support et dans le sens vertical par les tôles extérieures,  Although the stopper is normally immobilized transversely by the support plate and vertically by the external plates,

<Desc/Clms Page number 2><Desc / Clms Page number 2>

une liaison rigide entre ledit stoppeur et ladite tôle support est rendue nécessaire en raison de la flexibilité des tôles nervurées extérieures 12 qui peuvent bailler et autoriser un glissement du stoppeur 20 entre la tôle support 18 et l'une des tôles extérieures 12.  a rigid connection between said stopper and said support plate is made necessary due to the flexibility of the outer ribbed sheets 12 which can yawn and allow the stopper 20 to slide between the support sheet 18 and one of the outer sheets 12.

Ainsi, la liaison entre le stoppeur 20 et la tôle support 18 est généralement réalisée par soudage, collage ou analogue. La demande de brevet FR-00. 12669 au nom du demandeur propose un procédé de fixation du stoppeur sur sa tôle support par expansion radiale dudit stoppeur.  Thus, the connection between the stopper 20 and the support sheet 18 is generally carried out by welding, gluing or the like. Patent application FR-00. 12669 in the name of the applicant proposes a method of fixing the stopper on its support sheet by radial expansion of said stopper.

Aussi, la présente invention vise à proposer un nouveau joint de culasse comprenant un stoppeur bord à bord sans liaison rigide entre le stoppeur et la tôle support, ledit stoppeur étant toutefois parfaitement maintenu en position.  Also, the present invention aims to provide a new cylinder head gasket comprising an edge to edge stopper without rigid connection between the stopper and the support plate, said stopper being however perfectly maintained in position.

A cet effet, l'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 deux tôles dites extérieures, au moins l'une d'elles comportant une nervure circulaire, entourant l'ouverture, ménagée à une distance d du bord de ladite ouverture, et d'autre part, une tôle support disposée entre les tôles extérieures, comprenant une ouverture de diamètre supérieure à l'ouverture des tôles extérieures afin de définir un espace dans lequel est disposé un stoppeur sous forme d'une cale annulaire de diamètre intérieur correspondant 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 la tôle support a une surface de contact plus importante que la surface de contact du stoppeur en regard.  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 two so-called external sheets, at least one of them comprising a rib circular, surrounding the opening, formed at a distance d from the edge of said opening, and on the other hand, a support sheet disposed between the external sheets, comprising an opening of diameter greater than the opening of the external sheets in order to define a space in which a stopper is arranged in the form of an annular shim of internal diameter corresponding to that of the opening and of external diameter substantially adjusted to the opening of the support sheet so as to be arranged edge to edge, characterized in that that the support sheet has a larger contact surface than the contact surface of the opposite stopper.

Selon un mode de réalisation préféré, cette différence de surfaces de contact est obtenue par déformation plastique du bord de la tôle support, ce dernier présentant des découpes de manière à former des languettes légèrement pliées, de préférence de manière alternée.  According to a preferred embodiment, this difference in contact surfaces is obtained by plastic deformation of the edge of the support sheet, the latter having cutouts so as to form slightly folded tongues, preferably alternately.

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 transversale d'un joint de culasse selon l'art antérieur,  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 cross-sectional view of a cylinder head gasket according to the prior art,

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

- la figure 2 est une vue de dessus d'un joint de culasse multi-cylindres, - la figure 3 est une vue en coupe transversale du joint de culasse de la figure 2, - la figure 4A est une vue en coupe transversale d'un joint de culasse selon l'invention en position repos, et - la figure 4B est une vue en coupe transversale d'un joint de culasse selon l'invention montrant la flexibilité des tôles extérieures.  - Figure 2 is a top view of a multi-cylinder cylinder head gasket, - Figure 3 is a cross-sectional view of the cylinder head gasket of Figure 2, - Figure 4A is a cross-sectional view of a cylinder head gasket according to the invention in the rest position, and - Figure 4B is a cross-sectional view of a cylinder head gasket according to the invention showing the flexibility of the outer sheets.

Sur les différentes figures, on a représenté un joint de culasse 110 comprenant au moins deux tôles extérieures 112, avec au moins une ouverture 114 correspondant à une chambre à combustion d'un bloc moteur, au moins l'une des tôles extérieures 112, et de préférence les deux, comportant une nervure 116 circulaire, entourant l'ouverture 114, ménagée à une distance d du bord de l'ouverture 114, la ou les nervures étant déformée (s) vers l'intérieur du joint.  In the various figures, there is shown a cylinder head gasket 110 comprising at least two external sheets 112, with at least one opening 114 corresponding to a combustion chamber of an engine block, at least one of the external sheets 112, and preferably both, comprising a circular rib 116, surrounding the opening 114, formed at a distance d from the edge of the opening 114, the rib or ribs being deformed towards the interior of the joint.

De façon connue, une tôle support intermédiaire 118 est interposée entre les tôles extérieures 112. La tôle support 118 comprend une ouverture concentrique à l'ouverture 114 des tôles extérieures 112, de diamètre supérieur à l'ouverture 114 afin de définir un espace dans lequel est disposé un stoppeur 120, sous forme d'une cale annulaire, de diamètre intérieur correspondant à celui de l'ouverture 114 et de diamètre extérieur sensiblement ajusté à l'ouverture de la tôle support, de manière à être disposé bord à bord.  In known manner, an intermediate support sheet 118 is interposed between the exterior sheets 112. The support sheet 118 comprises an opening concentric with the opening 114 of the exterior sheets 112, of diameter greater than the opening 114 in order to define a space in which is disposed a stopper 120, in the form of an annular shim, of internal diameter corresponding to that of the opening 114 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 122 d'épaisseur X1 supérieure à l'épaisseur X2 de la tôle support 118 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 122 of thickness X1 greater than the thickness X2 of the support sheet 118 in order to constitute a limiter for crushing the ribs, a first sealing barrier and to allow the arching of the minus an outer sheet 12 so as to limit the deflections of the latter in operation.

Selon les cas, le diamètre extérieur du stoppeur 120 peut être inférieur à celui des nervures 116, si bien que la tôle support 118 est intercalée entre les nervures 116 ou bien être supérieur à celui des nervures 116, comme illustré par les figures 3,4A et 4B, si bien qu'une zone 124 dudit stoppeur  Depending on the case, the outside diameter of the stopper 120 may be less than that of the ribs 116, so that the support plate 118 is interposed between the ribs 116 or else be greater than that of the ribs 116, as illustrated in FIGS. 3,4A and 4B, so that a zone 124 of said stopper

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

d'épaisseur inférieur à X1 est intercalée entre les nervures 116 comme illustré par la figure 3.  of thickness less than X1 is interposed between the ribs 116 as illustrated in FIG. 3.

Cette dernière variante a pour avantages d'intercaler entre les nervures 116 une pièce d'une précision relativement importante, le stoppeur étant parfaitement calibré, et d'obtenir une distance inter-cylindre entre les ouvertures 112 plus réduite du fait que seul le stoppeur 120 est disposé entre lesdites ouvertures 112 comme illustré par la figure 2.  The latter variant has the advantages of interposing between the ribs 116 a piece of relatively high precision, the stopper being perfectly calibrated, and of obtaining a smaller inter-cylinder distance between the openings 112 because only the stopper 120 is disposed between said openings 112 as illustrated in FIG. 2.

Le stoppeur 120 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 120 may 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.

Selon l'invention, de manière à maintenir le stoppeur, la tôle support 118 a une surface de contact plus importante que la surface de contact du stoppeur 120 en regard.  According to the invention, in order to maintain the stopper, the support plate 118 has a larger contact surface than the contact surface of the stopper 120 opposite.

Selon un mode de réalisation illustré par les figures 3,4A et 4B, la différence de surfaces de contact est obtenue par déformation plastique du bord 126 de la tôle support 118 afin d'augmenter la surface de contact. Ainsi, à partir d'une épaisseur donnée de la tôle support, éventuellement identique à celle de l'art antérieur, il est possible d'augmenter artificiellement la surface de contact, cette dernière ayant une épaisseur fictive correspondant à l'écart

Figure img00040001

entre les points les plus haut et les points les plus bas de la déformation. According to an embodiment illustrated in FIGS. 3,4A and 4B, the difference in contact surfaces is obtained by plastic deformation of the edge 126 of the support sheet 118 in order to increase the contact surface. Thus, from a given thickness of the support sheet, possibly identical to that of the prior art, it is possible to artificially increase the contact surface, the latter having a fictitious thickness corresponding to the difference
Figure img00040001

between the highest points and the lowest points of the deformation.

Selon une première variante, le bord 126 comprend des ondulations.  According to a first variant, the edge 126 comprises undulations.

Selon une autre variante, illustrée par les figures 3,4A et 4B, le bord 126 présente des découpes de manière à former des languettes 128 qui sont légèrement pliées certaines vers le haut, d'autre vers le bas, de préférence de manière alternée.  According to another variant, illustrated by FIGS. 3,4A and 4B, the edge 126 has cutouts so as to form tabs 128 which are slightly bent some upwards, others downwards, preferably alternately.

Selon l'agencement de l'invention, on obtient une butée plastique susceptible d'empêcher le glissement du stoppeur entre la tôle support et l'une des tôles extérieures lorsque ces dernières s'écartent. Comme nous l'avons vu, cette butée peut être réalisée par emboutissage ou par découpe et  According to the arrangement of the invention, a plastic stop is obtained capable of preventing the sliding of the stopper between the support sheet and one of the outer sheets when the latter move apart. As we have seen, this stop can be produced by stamping or by cutting and

<Desc/Clms Page number 5><Desc / Clms Page number 5>

pliage permettant d'obtenir une épaisseur fictive de la tôle support supérieure à celle du stoppeur. Cette butée est dite plastique car elle peut éventuellement se comprimer au moment du montage du joint.  folding to obtain a fictitious thickness of the support sheet greater than that of the stopper. This stop is said to be plastic because it can possibly compress when the seal is assembled.

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 profil du stoppeur, les matériaux utilisés, la réalisation des tôles qui peuvent être chacune constituée d'un empilage de tôles ainsi que le profils et la positions des nervures. 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 profile of the stopper, the materials used, the production of the sheets which can each consist of a stack of sheets as well as the profiles and positions of the ribs.
