Abstract
Description
L'invention concerne un dispositif d'embrayage pour véhicule automobile destiné à être associé à une boite de vitesses comprenant deux arbres primaires. The invention relates to a clutch device for a motor vehicle intended to be associated with a gearbox comprising two primary shafts.
Les embrayages classiques ont été conçus pour des vehicules automobiles comportant une boîte de vitesses à seul arbre primaire. Conventional clutches have been designed for motor vehicles comprising a gearbox with a single primary shaft.
Cependant, la conception des boîtes de vitesses est en cours d'évolution et, notamment dans un souci de standardisation, certaines boîtes de vitesses conçues par la demanderesse comportent deux arbres primaires coaxiaux. However, the design of gearboxes is evolving and, in particular for the sake of standardization, some gearboxes designed by the applicant have two primary coaxial shafts.
La présence de ces deux arbres primaires donc necessité l'installation de deux embrayages distincts, exemple des embrayages monodisques à sec, pour agir chacun de ces arbres. The presence of these two primary shafts therefore requires the installation of two separate clutches, for example dry single-plate clutches, to act on each of these trees.
Ces deux embrayages augmentent considérablement l'encombrement et la taille du carter d'embrayage. De ce fait, le groupe moto-propulseur ne peut plus être monté transversalement dans un véhicule car il interfère alors avec le brancard, ce qui nuit au rayon de braquage du véhicule. These two clutches considerably increase the size and size of the clutch housing. Therefore, the powertrain can no longer be mounted transversely in a vehicle because it then interferes with the stretcher, which affects the turning radius of the vehicle.
L'invention a pour objet de pallier ces inconvénients en proposant un dispositif d'embrayage pour une boîte de vitesses à deux arbres primaires, de conception compacte, ce dispositif d'embrayage permettant de réduire l'encombrement et la taille du carter d'embrayage correspondant. Ainsi, l'invention concerne un dispositif d'embrayage pour véhicule automobile, destiné à être intercalé entre volant d'inertie solidaire de l'arbre de vilebrequin un moteur thermique et une ligne primaire motrice une boîte de vitesses comprenant deux arbres primaires, caractérisé en ce qu'il comprend - un plateau d'embrayage lié en rotation avec ledit volant, - un premier et deuxième disques disposés de part et d'autre dudit plateau d'embrayage, chacun d'eux étant monté coulissant sur un des deux arbres primaires en étant solidaire en rotation de cet arbre, - un premier et deuxième organes presseurs disposés de l'autre côté chacun des deux disques par rapport audit plateau d'embrayage et, - un premier et un deuxième diaphragmes liés en rotation avec ledit volant, chaque diaphragme sollicitant un des deux organes presseurs pour solidariser ou désolidariser chacun des disques avec ledit plateau d'embrayage et ainsi solidariser ou désolidariser chacun des arbres primaires avec l'arbre du moteur thermique. The object of the invention is to overcome these drawbacks by proposing a clutch device for a gearbox with two primary shafts, of compact design, this clutch device making it possible to reduce the size and size of the clutch housing. corresponding. Thus, the invention relates to a clutch device for a motor vehicle, intended to be interposed between flywheel integral with the crankshaft, a heat engine and a primary drive line, a gearbox comprising two primary shafts, characterized in what it includes - a clutch plate linked in rotation with said flywheel, - a first and second discs arranged on either side of said clutch plate, each of them being slidably mounted on one of the two primary shafts by being integral in rotation with this shaft, - a first and second pressing members arranged on the other side each of the two discs with respect to said clutch plate and, - a first and a second diaphragm linked in rotation with said flywheel, each diaphragm urging one of the two pressing members to secure or disengage each of the discs with said clutch plate and thus secure or disengage c each of the primary shafts with the engine shaft.
De préférence, le dispositif d'embrayage comporte deux mécanismes supportant les diaphragmes qui sont fixés sur le volant d'inertie. Preferably, the clutch device comprises two mechanisms supporting the diaphragms which are fixed to the flywheel.
Dans ce cas, les deux mécanismes sont avantageusement symétriques par rapport audit plateau d'embrayage. In this case, the two mechanisms are advantageously symmetrical with respect to said clutch plate.
L'invention concerne également un véhicule automobile comportant une ligne primaire motrice d'une boîte de vitesses qui comprend deux arbres primaires et un volant d'inertie évidé, solidaire de l'arbre de vilebrequin d' moteur thermique, dans lequel est au moins partiellement logé un dispositif d'embrayage selon l'invention. The invention also relates to a motor vehicle comprising a primary drive line of a gearbox which comprises two primary shafts and a hollow flywheel, integral with the crankshaft of the heat engine, in which is at least partially housed a clutch device according to the invention.
L'invention sera mieux comprise et d'autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement dans la description qui suit et qui est faite au regard de la figure 1. Cette figure 1 (figure unique) est vue générale schématique du dispositif d'embrayage selon l'invention, représenté selon une demie coupe, le plan coupe passant par l'axe commun XX' de l'arbre de vilebrequin et des deux arbres primaires de la boîte de vitesses Sur la droite de la figure 1, la référence 1 désigne la portion d'extrémité de l'arbre de vilebrequin d'un moteur thermique qui n'est pas représenté. The invention will be better understood and other objects, advantages and characteristics thereof will appear more clearly in the description which follows and which is given with reference to FIG. 1. This FIG. 1 (single figure) is a schematic general view of the clutch device according to the invention, shown in half a section, the sectional plane passing through the common axis XX ′ of the crankshaft and of the two primary shafts of the gearbox On the right of FIG. 1, reference 1 designates the end portion of the crankshaft of a heat engine which is not shown.
La boîte de vitesses, non représentée, est logée à l'intérieur d' carter référencé C. La ligne primaire de cette boîte vitesses est constituée d'une paire d'arbres, à savoir un arbre principal 2 et un arbre auxiliaire tubulaire 3. L'arbre creux auxiliaire 3 est traversé par l'arbre principal 2 et il est libre en rotation par rapport à ce dernier. De plus, l'arbre principal 2 est plus long que l'arbre 3 et il dépasse largement de l'arbre 3 à son extrémité située du côté de l'arbre 1, comme l'illustre la figure. The gearbox, not shown, is housed inside a casing referenced C. The primary line of this gearbox consists of a pair of shafts, namely a main shaft 2 and a tubular auxiliary shaft 3. The auxiliary hollow shaft 3 is crossed by the main shaft 2 and it is free to rotate relative to the latter. In addition, the main shaft 2 is longer than the shaft 3 and it largely protrudes from the shaft 3 at its end situated on the side of the shaft 1, as illustrated in the figure.
A l'entrée de la boîte de vitesses, la portion correspondante 30 de l'arbre 3 est guidée dans un palier à roulement 300 porté par le carter C. At the entrance to the gearbox, the corresponding portion 30 of the shaft 3 is guided in a rolling bearing 300 carried by the casing C.
De manière connue, l'extrémité de l'arbre de vilebrequin 1 solidaire d'un disque 10 sur lequel est monté un volant inertie 11. Le disque 10 est percé d'un alésage central servant au guidage en rotation de la portion d'extrémité 20 de l'arbre au moyen d'un roulement 12. In known manner, the end of the crankshaft 1 secured to a disc 10 on which is mounted an inertia flywheel 11. The disc 10 is pierced with a central bore used for guiding in rotation the end portion 20 of the shaft by means of a bearing 12.
arbres 1, 2 et 3 sont ainsi mutuellement centrés selon l'axe XX', le dispositif d'embrayage 4 selon l'invention permettant la solidarisation ou la désolidarisation relative en rotation de et/ou l'autre des deux arbres primaires 2 et 3 avec arbre de vilebrequin 1. shafts 1, 2 and 3 are thus mutually centered along the axis XX ′, the clutch device 4 according to the invention allowing the relative attachment or disengagement in rotation of and / or the other of the two primary shafts 2 and 3 with crankshaft 1.
Le dispositif d'embrayage 4 comprend tout d'abord un plateau d'embrayage 49 qui est lié en rotation avec le volant inertie 11. The clutch device 4 firstly comprises a clutch plate 49 which is linked in rotation with the flywheel 11.
A effet, le volant moteur 11 utilise est par exemple évidé de façon à comporter partie sensiblement annulaire 13 qui est centrée sur axe XX'. Indeed, the flywheel 11 uses is for example hollowed out so as to comprise a substantially annular part 13 which is centered on axis XX ′.
Cette configuration permet également de loger dans le volant 11 une partie du dispositif d'embrayage 4, ce qui augmente la compacité de l'ensemble. This configuration also makes it possible to accommodate part of the clutch device 4 in the flywheel 11, which increases the compactness of the assembly.
Ainsi, le plateau d'embrayage 49 est fixé à la partie annulaire 13 du volant 11 par des moyens de fixation appropriés référencés 14. Thus, the clutch plate 49 is fixed to the annular part 13 of the flywheel 11 by suitable fixing means referenced 14.
Le dispositif d'embrayage 4 comprend également deux disques 40 et 41 disposés de part et d'autre plateau d'embrayage 49. The clutch device 4 also comprises two discs 40 and 41 arranged on either side of the clutch plate 49.
Chaque disque 40, respectivement 41, est pourvu de garnitures de friction et son moyeu 400, respectivement 410 est rainuré. Ce moyeu s'engage sur des cannelures 401, respectivement 411, prévues sur l'arbre 3, respectivement 2. Each disc 40, respectively 41, is provided with friction linings and its hub 400, respectively 410 is grooved. This hub engages on grooves 401, respectively 411, provided on the shaft 3, respectively 2.
Ainsi, chacun des disques 40, respectivement 41, peut coulisser en translation selon l'axe XX' sur l'arbre 3, respectivement 2, tout en étant constamment solidaire en rotation de cet arbre. Thus, each of the disks 40, respectively 41, can slide in translation along the axis XX 'on the shaft 3, respectively 2, while being constantly integral in rotation with this shaft.
Le dispositif d'embrayage 4 comporte également deux organes presseurs annulaires 42 et 43. L'organe presseur référencé 42 est disposé de l'autre côté du disque 40 par rapport au plateau d'embrayage, tandis que l'organe presseur 43 est disposé de l'autre côté du disque 41 par rapport au plateau d'embrayage. The clutch device 4 also comprises two annular pressing members 42 and 43. The pressing member referenced 42 is arranged on the other side of the disc 40 relative to the clutch plate, while the pressing member 43 is arranged the other side of the disc 41 relative to the clutch plate.
Chacun de ces organes presseurs 42, 43 sollicité par un disque élastique ou diaphragme 44, Chacun de ces diaphragmes 44, respectivement 45, est lié en rotation avec le volant 11 par l'intermédiaire d' mécanisme 46, respectivement 47. Each of these pressing members 42, 43 urged by an elastic disc or diaphragm 44, Each of these diaphragms 44, respectively 45, is linked in rotation with the flywheel 11 by means of mechanism 46, respectively 47.
Comme illustré sur la figure 1, les mécanismes et 47 ont de préférence une forme symétrique l'une l'autre et sont disposés également de façon symétrique rapport au plateau d'embrayage 49. Les deux mécanismes 46 et 47 sont, dans cet exemple réalisation, fixés sur la partie annulaire 13 du volant 11 par les moyens de fixation 14 également utilisés pour le plateau d'embrayage. As illustrated in Figure 1, the mechanisms and 47 preferably have a symmetrical shape to each other and are also arranged symmetrically relative to the clutch plate 49. The two mechanisms 46 and 47 are, in this example embodiment , fixed on the annular part 13 of the flywheel 11 by the fixing means 14 also used for the clutch plate.
Le diaphragme 44 peut se déformer pour prendre sélectivement une disposition légèrement concave, avec concavité tournée vers le volant 11 comme illustré traits pointillés sur la figure 1, soit une configuration également légèrement concave mais de courbure opposée, comme illustré en traits pleins sur la figure 1, selon que sa partie centrale est soumise ou non à une poussée axiale, selon l'axe XX', en direction de l'arbre 1. The diaphragm 44 can be deformed to selectively take a slightly concave arrangement, with a concavity facing the flywheel 11 as illustrated with dotted lines in FIG. 1, ie a configuration also slightly concave but of opposite curvature, as illustrated in solid lines in FIG. , depending on whether its central part is subjected or not to an axial thrust, along the axis XX ', in the direction of the shaft 1.
Cette poussée axiale est imprimée au moyen d'une butée hydraulique 48, dont le piston 480 porte sur la partie centrale annulaire du diaphragme 44 par l'intermédiaire d'un plateau de roulement 440. Dans la position illustrée en traits pleins à la figure 1, le piston 480 n'exerce aucune poussée sur plateau de roulement 440. Le diaphragme 44 sollicite donc l'organe pousseur 42, le disque 40 est alors déplacé la droite, ce qui a pour effet d'emprisonner avec certain serrage les garnitures du disque 40 entre l'organe presseur 42 et le plateau d'embrayage 49. Ainsi la solidarisation du disque 40 et, corrélativement, de l'arbre 3, avec l'arbre 1 est assurée en rotation. This axial thrust is impressed by means of a hydraulic stop 48, the piston 480 of which bears on the annular central part of the diaphragm 44 by means of a rolling plate 440. In the position illustrated in solid lines in FIG. 1 , the piston 480 exerts no thrust on the rolling plate 440. The diaphragm 44 therefore urges the pusher member 42, the disc 40 is then moved to the right, which has the effect of trapping the linings of the disc with certain tightness 40 between the pressing member 42 and the clutch plate 49. Thus the connection of the disc 40 and, correspondingly, of the shaft 3, with the shaft 1 is ensured in rotation.
Lorsque le piston 480 exerce une poussée contre plateau de roulement 440, ceci provoque la déformation diaphragme 44 qui prend la position illustrée pointilles sur la figure 1, cette déformation permettant, grâce à dispositif annexe, le déplacement de l'organe pousseur 42 vers la gauche et, corrélativement, le débrayage. When the piston 480 exerts a thrust against the rolling plate 440, this causes the diaphragm deformation 44 which takes the position illustrated with dots in FIG. 1, this deformation allowing, thanks to the annexed device, the displacement of the pusher member 42 to the left and, correspondingly, the declutching.
Le diaphragme 45 se comporte de façon symétrique par rapport au diaphragme 44. The diaphragm 45 behaves symmetrically with respect to the diaphragm 44.
Ainsi, dans la disposition illustrée en traits pleins à la figure 1, le diaphragme prend une configuration légèrement concave, dont la concavité est tournée vers l'arbre 1, le diaphragme 45 n'étant soumis à aucune poussée provenant de la butée hydraulique qui lui est associée et qui n'est pas représentée à la figure 1. Dans cette position, le diaphragme 45 assure solidarisation en rotation du disque 41 corrélativement, de l'arbre 2, avec l'arbre de vilebrequin 1. Thus, in the arrangement illustrated in solid lines in FIG. 1, the diaphragm assumes a slightly concave configuration, the concavity of which faces the shaft 1, the diaphragm 45 not being subjected to any thrust coming from the hydraulic stop which is associated and which is not represented in FIG. 1. In this position, the diaphragm 45 ensures the rotation 41 of the disc 41 correlatively, of the shaft 2, with the crankshaft 1.
Lorsque la butée hydraulique correspondante exerce une poussée sur la partie centrale du diaphragme 45 l'intermédiaire du plateau de roulement 450, elle provoque sa déformation et le diaphragme 45 prend configuration légèrement concave, mais de courbure opposée, ce qui entraîne le débrayage. When the corresponding hydraulic stop exerts a thrust on the central part of the diaphragm 45 via the rolling plate 450, it causes its deformation and the diaphragm 45 takes a slightly concave configuration, but of opposite curvature, which causes disengagement.
De préférence, les disques 40 et 41 comportent des moyeux amortisseurs. Preferably, the discs 40 and 41 comprise damping hubs.
La description qui précède montre que le dispositif d'embrayage selon l'invention est conçu pour une boîte de vitesses comportant deux arbres primaires et qu'il présente un encombrement réduit, notamment grâce à un plateau d'embrayage commun à deux disques. La réduction des éléments nécessaires pour réaliser l'embrayage ou le débrayage des deux arbres primaires permet de rendre le dispositif d'embrayage plus compact. Ceci est favorisé par la disposition symétrique des pièces par rapport au plateau d'embrayage. The above description shows that the clutch device according to the invention is designed for a gearbox comprising two primary shafts and that it has a reduced bulk, in particular thanks to a clutch plate common to two discs. The reduction of the elements necessary to achieve the clutch or the disengagement of the two primary shafts makes it possible to make the clutch device more compact. This is favored by the symmetrical arrangement of the parts with respect to the clutch plate.
La taille l'encombrement réduits du dispositif d'embrayage sont encore mieux utilisés grâce à un volant d'inertie spécifique, partiellement évidé dans lequel peut être logé partiellement le dispositif d'embrayage selon l'invention Les signes de référence insérés après les caractéristiques techniques figurant dans les revendications pour seul but de faciliter la compréhension de dernières et ne sauraient en limiter la portée.The reduced size and size of the clutch device are even better used thanks to a specific flywheel, partially hollowed out in which the clutch device according to the invention can be partially housed. The reference signs inserted after the technical characteristics appearing in the claims for the sole purpose of facilitating the understanding of the latter and cannot limit their scope.
