Description

Dispositif d'amortissement  Damping device
La présente invention se rapporte à un dispositif d'amortissement, notamment pour double embrayage tel qu'un double embrayage humide ou pour tout système de transmission pour groupe motopropulseur de véhicule hybride. L'invention peut encore s'appliquer à un système de transmission automatique.  The present invention relates to a damping device, especially for double clutch such as a double wet clutch or for any transmission system for a hybrid vehicle powertrain. The invention can still be applied to an automatic transmission system.
Un tel dispositif d'amortissement vise à filtrer tout ou partie des oscillations de torsion issues des acyclismes du moteur thermique.  Such a damping device is intended to filter all or part of the torsional oscillations resulting from the acyclisms of the heat engine.
Dans ce but, il est connu de prévoir un dispositif d'amortissement comprenant :  For this purpose, it is known to provide a damping device comprising:
- un composant primaire apte à être solidarisé à un vilebrequin,  a primary component capable of being secured to a crankshaft,
- un composant secondaire apte à transmettre le couple du composant primaire vers une boîte de vitesses, et a secondary component capable of transmitting the torque of the primary component to a gearbox, and
- une pluralité d'organes de rappel élastique coopérant d'une part avec le composant primaire et d'autre part avec le composant secondaire de manière à limiter la rotation du composant secondaire par rapport au composant primaire autour d'un axe de rotation.  a plurality of resilient return members cooperating on the one hand with the primary component and on the other with the secondary component so as to limit the rotation of the secondary component with respect to the primary component around an axis of rotation.
Un tel dispositif d'amortissement peut porter un module d'amortissement pendulaire bien connu.  Such a damping device may carry a well-known pendulum damping module.
Il est nécessaire de limiter les déplacements axiaux du composant primaire par rapport au composant secondaire. Une solution connue est de prévoir :  It is necessary to limit the axial displacements of the primary component relative to the secondary component. A known solution is to provide:
- une rondelle en plastique sur le moyeu du composant primaire pour former une butée pour le déplacement axial du composant primaire en rapprochement du composant secondaire, et a plastic washer on the hub of the primary component to form a stop for the axial displacement of the primary component towards the secondary component, and
- une rondelle métallique sertie sur ce moyeu primaire pour former une butée pour le déplacement axial du composant primaire en éloignement du composant secondaire. - A metal washer crimped on the primary hub to form a stop for the axial displacement of the primary component away from the secondary component.
La présence de la rondelle métallique empêche que le composant secondaire soit assemblé à l'état monté sur le composant primaire. En effet, une étape de sertissage de la rondelle métallique sur le moyeu du composant primaire rend nécessaire un accès au moyeu du composant primaire, ce qui n'est plus possible une fois le moyeu du composant secondaire assemblé. Il est ainsi nécessaire de n'assembler d'abord sur le composant primaire qu'une partie du composant secondaire, puis de sertir la rondelle métallique sur le moyeu du composant primaire, puis de fixer enfin le moyeu du composant secondaire avec la partie de ce composant secondaire déjà assemblée sur le composant primaire. Une telle succession d'étapes est complexe et coûteuse. En outre, la rondelle métallique sertie sur le moyeu du composant primaire a un coût non négligeable et une durée de vie limitée.  The presence of the metal washer prevents the secondary component from being assembled in the mounted state on the primary component. Indeed, a step of crimping the metal washer on the hub of the primary component makes it necessary access to the hub of the primary component, which is no longer possible once the hub of the secondary component assembled. It is thus necessary to first assemble on the primary component only a portion of the secondary component, then to crimp the metal washer on the hub of the primary component, then to finally fix the hub of the secondary component with the part of this secondary component already assembled on the primary component. Such a succession of steps is complex and expensive. In addition, the metal washer crimped on the hub of the primary component has a significant cost and a limited life.
Enfin, l'équilibrage du composant secondaire pour remédier au problème de balourd ne peut se faire sur la totalité du composant secondaire puisque le moyeu de ce composant secondaire n'est assemblé sur le composant primaire qu'en toute fin de processus, de sorte que l'équilibrage est effectué sur une partie seulement du composant secondaire. Un tel équilibrage n'est ainsi pas pleinement satisfaisant. Finally, the balancing of the secondary component to remedy the unbalance problem can not be done on the entire secondary component since the hub of this secondary component is assembled on the primary component only at the very end of the process, so that balancing is performed on only part of the secondary component. Such balancing is thus not fully satisfactory.
Il existe un besoin pour remédier à tout ou partie des inconvénients précités.  There is a need to remedy all or some of the aforementioned drawbacks.
L'invention a pour but de répondre à ce besoin et elle y parvient, selon l'un de ses aspects, à l'aide d'un dispositif d'amortissement comprenant :  The invention aims to meet this need and it achieves, in one aspect, with the aid of a damping device comprising:
- un composant primaire apte à être solidarisé à un vilebrequin,  a primary component capable of being secured to a crankshaft,
- un composant secondaire apte à transmettre le couple du composant primaire vers une boîte de vitesses, et  a secondary component capable of transmitting the torque of the primary component to a gearbox, and
- une pluralité d'organes de rappel élastique coopérant d'une part avec le composant primaire et d'autre part avec le composant secondaire de manière à limiter la rotation du composant secondaire par rapport au composant primaire autour d'un axe de rotation,  a plurality of resilient return members cooperating on the one hand with the primary component and on the other with the secondary component so as to limit the rotation of the secondary component with respect to the primary component around an axis of rotation,
le composant primaire portant un élément en plastique apte à venir en butée contre le composant secondaire lors d'un déplacement du composant primaire en rapprochement du composant secondaire, et the primary component carrying a plastic element adapted to abut against the secondary component during a displacement of the primary component towards the secondary component, and
le composant secondaire comprenant un élément métallique définissant une butée pour le déplacement axial du composant primaire en éloignement du composant secondaire. the secondary component comprising a metal element defining a stop for the axial displacement of the primary component away from the secondary component.
Selon l'invention, la butée pour le déplacement axial du composant primaire par rapport au composant secondaire ne se fait plus via des éléments uniquement portés par le composant primaire. L'assemblage du composant secondaire sur le composant primaire peut se faire en une seule étape et, préalablement à cette seule étape, le composant secondaire peut être déjà avoir été monté.  According to the invention, the stop for the axial displacement of the primary component relative to the secondary component is no longer via elements solely carried by the primary component. The assembly of the secondary component on the primary component can be done in a single step and, prior to this single step, the secondary component can already be mounted.
Le composant primaire est apte à être solidarisé à un vilebrequin, ce qui signifie qu'il pourra être rigidement fixé par des moyens de fixation tels que des rivets à ce vilebrequin. Cette solidarisation peut ainsi être permanente. Cette solidarisation du composant primaire au vilebrequin est alors différente de celle qui se produirait sélectivement via un embrayage, par exemple.  The primary component is able to be secured to a crankshaft, which means that it can be rigidly fixed by fastening means such as rivets to the crankshaft. This solidarity can be permanent. This attachment of the primary component to the crankshaft is then different from that which would occur selectively via a clutch, for example.
Au sens de la présente demande :  For the purposes of this application:
- « axialement » signifie « parallèlement à l'axe de rotation»,  - "axially" means "parallel to the axis of rotation",
- « radialement » signifie « le long d'un axe appartenant à un plan orthogonal à l'axe de rotation et coupant cet axe de rotation du support»,  - "radially" means "along an axis belonging to a plane orthogonal to the axis of rotation and intersecting that axis of rotation of the support",
- « angulairement » ou « circonférentiellement » signifie « autour de l'axe de rotation»,  - "angularly" or "circumferentially" means "around the axis of rotation",
- « orthoradialement » signifie « perpendiculairement à une direction radiale »,  - "orthoradially" means "perpendicular to a radial direction",
- « solidaire » signifie « rigidement couplé ».  - "solidarity" means "rigidly coupled".
L'élément en plastique peut être rapporté, notamment par encliquetage, sur une plaque d'arrêt du composant primaire. L'élément en plastique est par exemple une rondelle. La rondelle présente par exemple : The plastic element may be attached, in particular by snapping, on a stop plate of the primary component. The plastic element is for example a washer. The puck presents for example:
- une portion annulaire s 'étendant tout autour de l'axe du dispositif, et  an annular portion extending all around the axis of the device, and
- des pattes permettant l'accrochage, notamment par encliquetage, de la rondelle sur la plaque d'arrêt. Chaque patte présente par exemple une extrémité libre venant se bloquer contre un bord de la plaque d'arrêt.  - Lugs for attachment, in particular by snapping, the washer on the stop plate. Each tab has for example a free end coming to lock against an edge of the stop plate.
La plaque d'arrêt peut présenter une portion annulaire s'étendant tout autour de l'axe du dispositif et contre laquelle vient en appui la portion annulaire de la rondelle lorsque celle-ci est accrochée sur la plaque d'arrêt. La plaque d'arrêt peut également comprendre des bras de fixation au reste du composant primaire, et la plaque peut comprendre, entre la portion annulaire et un bras de fixation, une portion de transition qui définit une ouverture dans laquelle une patte de la rondelle en plastique vient se positionner.  The stop plate may have an annular portion extending all around the axis of the device and against which bears the annular portion of the washer when it is hooked on the stop plate. The stop plate may also comprise fixing arms to the remainder of the primary component, and the plate may comprise, between the annular portion and a fixing arm, a transition portion which defines an opening in which a tab of the washer in plastic comes to position itself.
Le composant primaire peut comprendre un moyeu et un flasque flexible, encore appelé « flexplate » en anglais, ce moyeu et ce flasque flexible étant assemblés à la plaque d'arrêt par de mêmes moyens de fixation, notamment des rivets ou des vis.  The primary component may comprise a hub and a flexible flange, also called "flexplate" in English, this hub and this flexible flange being assembled to the stop plate by the same fastening means, including rivets or screws.
Le composant primaire peut encore comprendre une couronne de démarreur reliée au moyeu via la flexplate.  The primary component may further comprise a starter ring connected to the hub via the flexplate.
Le composant primaire peut former un volant primaire. En variante, le volant primaire peut être rigide, étant notamment dépourvu de moyeu et de flexplate.  The primary component can form a primary flywheel. Alternatively, the primary flywheel can be rigid, including without hub and flexplate.
La plaque d'arrêt peut venir directement au contact du moyen de fixation, notamment du rivet ou de la vis, qui assemble simultanément le moyeu, le flasque flexible et la plaque d'arrêt. Dans ce cas, la plaque d'arrêt peut être réalisée en acier.  The stop plate can come into direct contact with the fastening means, in particular the rivet or the screw, which simultaneously assembles the hub, the flexible flange and the stop plate. In this case, the stop plate can be made of steel.
En variante, la plaque d'arrêt ne vient pas directement au contact du moyen de fixation, notamment du rivet ou de la vis, qui assemble simultanément le moyeu, le flasque flexible et la plaque d'arrêt. Une pièce additionnelle est alors présente et interposée, directement ou non, entre la plaque d'arrêt et le moyen de fixation. La pièce additionnelle peut alors être réalisée en plastique.  In a variant, the stop plate does not come into direct contact with the fastening means, in particular the rivet or the screw, which simultaneously assembles the hub, the flexible flange and the stop plate. An additional piece is then present and interposed, directly or indirectly, between the stop plate and the fixing means. The additional piece can then be made of plastic.
La plaque d'arrêt peut venir en butée contre l'élément métallique lors d'un déplacement axial du composant primaire en éloignement du composant secondaire.  The stop plate can abut against the metal element during axial displacement of the primary component away from the secondary component.
L'élément métallique est par exemple une rondelle.  The metal element is for example a washer.
L'élément métallique peut être monté sur le composant secondaire après assemblage de ce composant secondaire sur le composant primaire.  The metal member may be mounted to the secondary component after assembling this secondary component to the primary component.
Lors de son montage sur le composant secondaire, l'élément métallique peut se déformer. When mounted on the secondary component, the metal element may deform.
A l'état assemblé, le dispositif d'amortissement peut être tel que le composant primaire présente un jeu axial par rapport au composant secondaire. Dans tout ce qui précède, l'élément en plastique, la plaque d'arrêt et la rondelle métallique peuvent respectivement comprendre des portions en regard les unes les autres axialement. In the assembled state, the damping device may be such that the primary component has an axial clearance with respect to the secondary component. In all the above, the plastic element, the stop plate and the metal washer may respectively comprise portions facing each other axially.
Le composant secondaire peut comprendre un moyeu dans lequel est ménagée une gorge, l'élément métallique définissant une butée pour le déplacement axial du composant primaire en éloignement du composant secondaire étant une rondelle montée dans cette gorge.  The secondary component may comprise a hub in which is formed a groove, the metal element defining a stop for the axial displacement of the primary component away from the secondary component being a washer mounted in this groove.
La gorge peut s'étendre sur 360° autour de l'axe du dispositif et ne recevoir qu'une unique rondelle métallique.  The groove can extend 360 ° around the axis of the device and receive only one metal washer.
Le composant secondaire peut encore comprendre un ou plusieurs joints d'étanchéité. Le moyeu du composant secondaire peut comprendre des cannelures, afin d'être emboîté sur un arbre d'entrée de boîte de vitesses ou sur un arbre d'entrée d'un double embrayage, à sec ou humide. Le dispositif, et notamment le composant secondaire, peut être dépourvu de module d'amortissement pendulaire.  The secondary component may further include one or more seals. The hub of the secondary component may comprise splines, to be fitted on a gearbox input shaft or on a double clutch drive shaft, dry or wet. The device, and in particular the secondary component, may be devoid of a pendulum damping module.
En variante, le composant secondaire peut porter un module d'amortissement pendulaire. Le module d'amortissement pendulaire peut présenter une pluralité de corps pendulaires guidés en déplacement via un ou plusieurs organes de roulement par rapport au moyeu du composant secondaire. Chaque corps pendulaire peut être disposé radialement à l'intérieur des organes de rappel élastique du dispositif, radialement à hauteur de ces organes de rappel élastique, ou radialement à l'extérieur de ces organes de rappel élastique.  Alternatively, the secondary component may carry a pendulum damping module. The pendulum damping module may have a plurality of pendular bodies guided in displacement via one or more rolling members relative to the hub of the secondary component. Each pendulum body may be disposed radially inside the elastic return members of the device, radially at height of these resilient return members, or radially outwardly of these elastic return members.
Le composant secondaire peut comprendre un flasque, encore appelé « voile » venant au contact des organes de rappel élastique. Les pistes de roulement coopérant avec les organes de roulement du module d'amortissement pendulaire peuvent être ménagées dans ce voile ou dans un support rigidement couplé à ce voile.  The secondary component may comprise a flange, also called "veil" coming into contact with the elastic return members. The rolling tracks cooperating with the running members of the pendulum damping module may be formed in the web or in a support rigidly coupled to the web.
Lors de l'assemblage du composant secondaire sur le composant primaire, le composant secondaire peut déjà comprendre à l'état assemblé : le moyeu, le voile et les corps pendulaires, et le cas échéant le ou les joints d'étanchéité.  During the assembly of the secondary component on the primary component, the secondary component can already include in the assembled state: the hub, the sail and the pendular bodies, and if necessary the seal or seals.
Le composant primaire peut définir deux portées diamétralement opposées, le composant secondaire comprenant deux bras, chacun des bras étant destiné à venir axialement en regard d'une portée, notamment en appui contre une portée, et coopérant avec des organes de rappel élastique lorsque le composant secondaire est assemblé sur le composant primaire.  The primary component may define two diametrically opposite bearing surfaces, the secondary component comprising two arms, each of the arms being intended to come axially opposite a bearing surface, in particular bearing against a bearing surface, and cooperating with resilient return members when the component secondary is assembled on the primary component.
Dans tout ce qui précède, le composant secondaire peut comprendre une pluralité d'éléments d'équilibrage. Plusieurs plaquettes d'équilibrage, par exemple dix plaquettes d'équilibrage, peuvent être disposées sur le composant secondaire. Ces plaquettes d'équilibrage sont par exemple fixées, notamment rivetées, sur la plaque du composant secondaire précitée. Comme déjà mentionné, grâce à l'invention, cet équilibrage se fait pour corriger le balourd du composant secondaire considéré dans sa totalité, et non seulement en partie. Dans tout ce qui précède, le dispositif d'amortissement est avantageusement dépourvu de moyens de guidage en rotation du composant secondaire par rapport au composant primaire, tels que des roulements ou paliers. In all of the above, the secondary component may comprise a plurality of balancing elements. Several balancing plates, for example ten balancing plates, can be arranged on the secondary component. These balancing plates are for example fixed, in particular riveted, on the plate of the aforementioned secondary component. As already mentioned, thanks to the invention, this balancing is done to correct the unbalance of the secondary component considered in its entirety, and not only in part. In all the foregoing, the damping device is advantageously devoid of means for rotating the secondary component relative to the primary component, such as bearings or bearings.
Les seuls éléments interposés en rotation entre le composant primaire et le composant secondaire du dispositif sont alors les organes de rappel élastique précités.  The only elements interposed in rotation between the primary component and the secondary component of the device are then the aforementioned elastic return members.
Les organes de rappel élastique sont par exemple des ressorts hélicoïdaux, par exemple droits ou courbes.  The elastic return members are for example helical springs, for example straight or curved.
L'invention a encore pour objet, selon un autre de ses aspects, un double embrayage, notamment un double embrayage humide, comprenant un dispositif d'amortissement tel que défini ci-dessus.  The invention further relates, in another of its aspects, a dual clutch, including a double wet clutch, comprising a damping device as defined above.
L'invention a encore pour objet, selon encore un autre de ses aspects, un groupe  Another subject of the invention is, according to yet another of its aspects, a group
motopropulseur hybride de véhicule, comprenant : Hybrid vehicle power train, comprising:
- un moteur thermique,  a heat engine,
- un moteur électrique, et  an electric motor, and
- un dispositif d'amortissement tel que défini ci-dessus. a damping device as defined above.
L'invention a encore pour objet, selon un autre de ses aspects, un procédé d'assemblage d'un dispositif d'amortissement, comprenant les étapes suivantes :  The invention further relates, in another of its aspects, to a method of assembling a damping device, comprising the following steps:
- disposer d'un composant secondaire, ce composant secondaire comprenant un moyeu, et de préférence un module d'amortissement pendulaire,  - Have a secondary component, this secondary component comprising a hub, and preferably a pendular damping module,
- assembler le composant secondaire sur un composant primaire du dispositif d'amortissement, ce composant primaire portant un élément en plastique définissant, une fois l'assemblage réalisé, une butée pour le déplacement axial du composant primaire en rapprochement du composant secondaire. - Assemble the secondary component on a primary component of the damping device, the primary component carrying a plastic element defining, once assembly is made, a stop for the axial displacement of the primary component towards the secondary component.
Le procédé peut comprendre l'étape consistant, ultérieurement à l'assemblage du composant secondaire sur le composant primaire, à mettre en place sur le composant secondaire une rondelle métallique définissant une butée pour le déplacement axial du composant primaire en éloignement du composant secondaire.  The method may comprise the step of, after assembly of the secondary component on the primary component, to set up on the secondary component a metal washer defining a stop for the axial displacement of the primary component away from the secondary component.
Tout ou partie des caractéristiques mentionnées en rapport avec le dispositif d'amortissement s'applique encore au procédé ci-dessus.  All or some of the features mentioned in connection with the damping device still apply to the above process.
A titre d'exemple, des éléments d'équilibrage peuvent avoir été rapportés sur le composant secondaire préalablement à son assemblage sur le composant primaire.  For example, balancing elements may have been reported on the secondary component prior to its assembly on the primary component.
L'étape d'assemblage peut être une étape unique réalisée en une seule fois.  The assembly step can be a single step performed at one time.
Lors de cette étape d'assemblage, le composant secondaire peut être formé par : le moyeu, un flasque apte à venir au contact des organes de rappel élastique, un module d'amortissement pendulaire, et un ou plusieurs joints d'étanchéité. Le procédé peut comporter une étape, préalable à l'étape d'assemblage du composant secondaire sur le composant primaire, lors de laquelle étape préalable des éléments d'équilibrage sont rapportés sur le composant secondaire. During this assembly step, the secondary component may be formed by: the hub, a flange adapted to come into contact with the elastic return members, a pendular damping module, and one or more seals. The method may comprise a step, prior in the step of assembling the secondary component on the primary component, in which preliminary step of the balancing elements are reported on the secondary component.
L'invention pourra être mieux comprise à la lecture de la description qui va suivre d'exemples non limitatifs de mise en œuvre de celle-ci et à l'examen du dessin annexé sur lequel :  The invention will be better understood on reading the following description of non-limiting examples of implementation thereof and on examining the appended drawing in which:
- la figure 1 est une vue d'un dispositif d'amortissement selon un exemple de mise en œuvre de l'invention, FIG. 1 is a view of a damping device according to an exemplary implementation of the invention,
- les figures 2 et 3 sont des vues similaires à la figure 1 ,  FIGS. 2 and 3 are views similar to FIG.
- la figure 4 représente de façon isolée le composant primaire du dispositif d'amortissement des figures 2 et 3, et  FIG. 4 is an isolated representation of the primary component of the damping device of FIGS. 2 and 3, and
- la figure 5 représente de façon isolée la plaque d'arrêt et la rondelle plastique de butée du composant primaire de la figure 4. FIG. 5 is an isolated representation of the stop plate and the plastic stop washer of the primary component of FIG. 4.
On a représenté sur la figure 1 un dispositif d'amortissement 1 selon un premier exemple de mise en œuvre de l'invention. Le dispositif d'amortissement 1 est par exemple destiné à être associé à un double embrayage humide ou à être intégré à un groupe motopropulseur hybride de véhicule.  FIG. 1 shows a damping device 1 according to a first embodiment of the invention. The damping device 1 is for example intended to be associated with a double wet clutch or to be integrated with a hybrid powertrain vehicle.
Le dispositif 1 comprend, comme on peut le voir sur la figure 1 :  The device 1 comprises, as can be seen in FIG.
- un composant primaire 2, qui se présente sous la forme d'un volant primaire, et  a primary component 2, which is in the form of a primary flywheel, and
- un composant secondaire 3.  - a secondary component 3.
Le volant primaire 2 peut comprendre :  The primary flywheel 2 can include:
- un moyeu 4, a hub 4,
- une flexplate 5,  a flexplate 5,
- une couronne de démarreur 6,  a starter ring 6,
- un joint métallique.  - a metal seal.
Ce volant primaire est apte à être fixé au vilebrequin d'un moteur thermique via des rivets non visibles sur les figures.  This primary flywheel is adapted to be attached to the crankshaft of a heat engine via rivets not visible in the figures.
Le composant secondaire 3 comprend:  Secondary component 3 comprises:
- un moyeu 12 présentant des cannelures 11 permettant son montage sur un arbre,  a hub 12 having splines 11 enabling it to be mounted on a shaft,
- un flasque 13, encore appelé « voile », et fixé via des rivets 15 sur le moyeu 12,  a flange 13, also called "sail", and fixed via rivets 15 to the hub 12,
- des corps pendulaires, chaque corps pendulaire comprenant deux masses pendulaires 14 respectivement disposée axialement d'un côté du voile, ce dernier jouant le rôle de support pour les corps pendulaires.  - Pendular bodies, each pendulum body comprising two pendular masses 14 respectively axially disposed on one side of the web, the latter acting as a support for the pendular bodies.
Le composant secondaire 3 intègre donc ici un module d'amortissement pendulaire dont le voile 13 forme le support. Le dispositif 1 comprend encore des organes de rappel élastique 18 limitant la rotation du composant secondaire 3 par rapport au volant primaire 2 autour de l'axe de rotation X. Deux ressorts 18 sont ici prévus et il s'agit de ressorts courbes. The secondary component 3 thus incorporates a pendular damping module whose web 13 forms the support. The device 1 also comprises elastic return members 18 limiting the rotation of the secondary component 3 relative to the primary flywheel 2 about the axis of rotation X. Two springs 18 are provided here and are curved springs.
Comme on peut le voir sur la figure 1, le voile 13 comprend dans cet exemple deux bras 20 définissant chacun une extension radiale et chacun de ces bras 20 vient en contact avec un ressort 18 lorsque le composant secondaire 3 se déplace en rotation autour de l'axe X par rapport au volant primaire 2. Les deux bras 20 sont ici diamétralement opposés.  As can be seen in FIG. 1, the web 13 comprises, in this example, two arms 20 each defining a radial extension and each of these arms 20 comes into contact with a spring 18 when the secondary component 3 moves in rotation about the X axis relative to the primary flywheel 2. The two arms 20 are here diametrically opposed.
Dans l'exemple décrit, le volant primaire définit une bordure pour le déplacement radial vers l'extérieur des ressorts 18.  In the example described, the primary flywheel defines a border for the radial displacement towards the outside of the springs 18.
Dans l'exemple décrit, le déplacement du volant primaire 2 par rapport au composant secondaire 3 est borné, comme cela va maintenant être décrit.  In the example described, the movement of the primary flywheel 2 relative to the secondary component 3 is bounded, as will now be described.
Dans ce but, le volant primaire 2 porte dans l'exemple décrit une rondelle en plastique 25 apte à venir en butée contre le composant secondaire 3 lorsque le volant primaire 2 se déplace axialement en rapprochement du composant secondaire 3, et le composant secondaire 3 comprend une rondelle métallique 26 qui définit une butée pour le déplacement axial du volant primaire 2 en éloignement du composant secondaire 3.  For this purpose, the primary flywheel 2 carries in the example described a plastic washer 25 adapted to abut against the secondary component 3 when the primary flywheel 2 moves axially towards the secondary component 3, and the secondary component 3 comprises a metal washer 26 which defines a stop for the axial displacement of the primary flywheel 2 away from the secondary component 3.
On constate sur les figures 2 à 5 que le volant primaire 2 comprend une plaque d'arrêt 30 fixée via des bras de fixation 32 au reste du volant primaire 2. Trois bras de fixation 32 sont par exemple prévus et répartis uniformément autour de l'axe X du dispositif 1. Chaque bras de fixation 32 présente dans l'exemple décrit un trou qui reçoit dans l'exemple décrit un rivet 33 venant fixer la plaque d'arrêt 30 simultanément au moyeu 4 et à la flexplate 5 du volant primaire 2. Ce rivet 33 s'étend ainsi à travers : le bras de fixation 32, la flexplate 5, et le moyeu 4. Le bras de fixation 32 vient alors directement au contact de la tête du rivet 33, étant avantageusement réalisé en acier.  It can be seen in FIGS. 2 to 5 that the primary flywheel 2 comprises a stop plate 30 fixed via attachment arms 32 to the remainder of the primary flywheel 2. Three attachment arms 32 are for example provided and uniformly distributed around the X axis of the device 1. Each fixing arm 32 has in the example described a hole which receives in the example described a rivet 33 coming to fix the stop plate 30 simultaneously to the hub 4 and the flexplate 5 of the primary flywheel 2 This rivet 33 thus extends through: the attachment arm 32, the flexplate 5, and the hub 4. The attachment arm 32 then comes into direct contact with the rivet head 33, advantageously being made of steel.
En plus de plusieurs bras de fixation 32, la plaque d'arrêt 30 comprend encore, dans l'exemple décrit, une portion annulaire 34 s'étendant tout autour de l'axe X du dispositif 1.  In addition to several fixing arms 32, the stop plate 30 also comprises, in the example described, an annular portion 34 extending all around the axis X of the device 1.
Entre la portion annulaire 34 et chaque bras de fixation 32, est prévue une portion de transition 36 dans laquelle est ménagée une ouverture 38 dont le rôle sera décrit par la suite.  Between the annular portion 34 and each attachment arm 32 is provided a transition portion 36 in which is formed an opening 38 whose role will be described later.
La plaque d'arrêt 30 joue dans l'exemple décrit le rôle de support pour la rondelle en plastique 25. La rondelle en plastique 25 comprend ici une portion annulaire 40 s'étendant tout autour de l'axe X du dispositif 1 et une pluralité de pattes 42, ici autant de pattes 42 qu'il y a de bras de fixation 32, chaque patte 42 permettant l'accrochage, ici par encliquetage, de la rondelle 25 sur la plaque d'arrêt 30. Chaque patte 42 présente dans cet exemple une extrémité libre 43 venant se bloquer contre la portion de transition 36. La rondelle métallique 26 définissant une butée pour le déplacement axial du volant primaire 2 en éloignement du composant secondaire 3 est ici engagée dans une gorge 45 ménagée dans le moyeu 12 du composant secondaire 3. La gorge 45 est par exemple unique et elle s'étend sur 360° autour de l'axe du dispositif 1. Cette gorge 45 est ici ménagée sur une surface radialement extérieure du moyeu, cette surface radialement extérieure étant sensiblement cylindrique. The stop plate 30 plays in the example described the role of support for the plastic washer 25. The plastic washer 25 here comprises an annular portion 40 extending all around the axis X of the device 1 and a plurality of tabs 42, here as many tabs 42 as there are fastening arms 32, each tab 42 allowing attachment, here by snapping, of the washer 25 on the stop plate 30. Each tab 42 present in this example a free end 43 coming to lock against the transition portion 36. The metal washer 26 defining a stop for the axial displacement of the primary flywheel 2 away from the secondary component 3 is here engaged in a groove 45 formed in the hub 12 of the secondary component 3. The groove 45 is for example unique and extends 360 ° about the axis of the device 1. This groove 45 is here formed on a radially outer surface of the hub, this radially outer surface being substantially cylindrical.
La rondelle métallique 26 forme ici un circlip.  The metal washer 26 forms a circlip here.
Plusieurs plaquettes d'équilibrage, par exemple dix plaquettes d'équilibrage, peuvent être disposées sur le composant secondaire 3. Ces plaquettes d'équilibrage sont par exemple fixées, notamment rivetées, sur le composant secondaire 3. Comme déjà mentionné, grâce à l'invention, cet équilibrage se fait pour corriger le balourd du composant secondaire considéré dans sa totalité, et non seulement en partie.  Several balancing plates, for example ten balancing plates, may be arranged on the secondary component 3. These balancing plates are for example fixed, in particular riveted, on the secondary component 3. As already mentioned, thanks to the Invention, this balancing is done to correct the unbalance of the secondary component considered in its entirety, and not only in part.
Dans tout ce qui précède, le dispositif d'amortissement est avantageusement dépourvu de moyens de guidage en rotation du composant secondaire par rapport au composant primaire, tels que des roulements ou paliers. Les seuls éléments interposés en rotation entre le composant primaire et le composant secondaire du dispositif sont alors les organes de rappel élastique précités.  In all the foregoing, the damping device is advantageously devoid of means for rotating the secondary component relative to the primary component, such as bearings or bearings. The only elements interposed in rotation between the primary component and the secondary component of the device are then the aforementioned elastic return members.
Les organes de rappel élastique sont par exemple des ressorts hélicoïdaux, par exemple droits ou courbes.  The elastic return members are for example helical springs, for example straight or curved.
L'invention n'est pas limitée à l'exemple qui vient d'être décrit. A la place d'un double embrayage humide, l'invention peut ainsi s'appliquer à un double embrayage à sec ou à un système de transmission automatique.  The invention is not limited to the example which has just been described. Instead of a double wet clutch, the invention can thus be applied to a double dry clutch or to an automatic transmission system.
