ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

La présente invention concerne des paliers pour pièces d'horlogerie, plus particulièrement du type permettant d'amortir les chocs. Les constructeurs de montres mécaniques ont conçu depuis longtemps de nombreux dispositifs permettant à un axe d'absorber l'énergie résultant d'un choc, notamment d'un choc latéral, par butée contre une paroi du trou du bloc de base qu'il traverse, tout en permettant un déplacement momentané du tigeron avant qu'il ne soit ramené à sa position de repos sous l'action d'un ressort.The present invention relates to bearings for timepieces, more particularly of the type for damping shocks. The mechanical watch manufacturers have long since designed numerous devices allowing an axis to absorb the energy resulting from an impact, in particular a side impact, by abutment against a wall of the hole of the base block that it crosses. while allowing a momentary movement of the tigeron before it is brought back to its rest position under the action of a spring.

Les figures 1 et 2 illustrent un dispositif dit à double cône inversé qui est actuellement utilisé dans des pièces d'horlogerie se trouvant sur le marché.The Figures 1 and 2 illustrate an inverted double-cone device that is currently used in timepieces on the market.

Un support 1, dont la base comporte un trou 2 pour le passage de l'axe de balancier 3 terminé par un tigeron 3a, permet de positionner un chaton 20 dans lequel sont immobilisées une pierre percée 4 traversée par le tigeron 3a et une pierre contre-pivot 5. Le chaton 20 est maintenu dans un logement 6 du support 1 par un ressort 10 qui comprend dans cet exemple des extensions radiales 9 comprimant la pierre contre-pivot 5. Le support 1 est une pièce de révolution comprenant un rebord circulaire 11. Ce rebord 11 est interrompu en deux endroits diamétralement opposés par une ouverture 12 de sorte à créer deux rebords semi-circulaires 11a, 11b. L'ouverture 12 est ménagée pour partie dans les deux rebords semi-circulaires 11a, 11b de façon à matérialiser deux retours 13. Le chaton 20 est maintenu dans un logement 6 du support 1 par des moyens élastiques tels un ressort 10 qui comprend dans cet exemple des extensions radiales 9 comprimant la pierre contre-pivot 5. Le ressort 10 est du type axiale et présente une forme de lyre agencée pour prendre appui sous les retours des rebords semi-circulaires 11a, 11b. Le logement 6 comporte deux portées 7, 7a en forme de cônes inversés sur lesquelles prennent appui des portées complémentaires 8, 8a du chaton 20, lesdites portées devant être exécutées avec une très grande précision. En cas de choc axial, la pierre percée 4, la pierre contre-pivot 5 et l'axe du balancier se déplacent et le ressort 10 agit seul pour ramener l'axe de balancier 3 dans sa position initiale. Le ressort 10 est dimensionné pour avoir une limite de déplacement de sorte qu'au-delà de cette limite, l'axe de balancier 3 arrive en contact avec des butées 14 permettant audit axe 3 d'absorber le choc, ce que les tigerons 3a de l'axe 3 ne peuvent faire sous peine de casser. En cas de choc latéral, c'est-à-dire lorsque l'extrémité du tigeron déséquilibre le chaton 20 hors de son plan de repos, le ressort 10 coopère avec les plans inclinés complémentaires 7, 7a ; 8, 8a pour recentrer le chaton 20. De tels paliers ont par exemple été vendus sous la marque Incabloc®. Ces ressorts peuvent être réalisés en phynox ou laiton et sont fabriqués par des moyens traditionnels de découpage.A support 1, whose base comprises a hole 2 for the passage of the balance shaft 3 terminated by a tigeron 3a, allows positioning a kitten 20 in which are immobilized a pierced stone 4 traversed by 3. The kitten 20 is held in a housing 6 of the support 1 by a spring 10 which comprises in this example radial extensions 9 compressing the stone against pivot 5. The support 1 is a part of revolution comprising a circular flange 11. This flange 11 is interrupted in two diametrically opposite locations by an opening 12 so as to create two semi-circular flanges 11a, 11b. The opening 12 is formed partly in the two semicircular edges 11a, 11b so as to materialize two returns 13. The kitten 20 is held in a housing 6 of the support 1 by elastic means such as a spring 10 which comprises in this example of the radial extensions 9 compressing the counter-pivot stone 5. The spring 10 is of the axial type and has a form of lyre arranged to bear under the return semicircular flanges 11a, 11b. The housing 6 comprises two bearing surfaces 7, 7a in the form of inverted cones on which support complementary bearing surfaces 8, 8a of the kitten 20, said bearing surfaces to be executed with very high accuracy. In the event of an axial impact, the pierced stone 4, the counter pivot stone 5 and the axis of the balance arm move and the spring 10 acts alone to bring the balance shaft 3 back to its initial position. The spring 10 is dimensioned to have a limit of displacement so that beyond this limit, the balance shaft 3 comes into contact with abutments 14 allowing said axis 3 to absorb the shock, which the rods 3a Axis 3 can not do without breaking. In case of lateral impact, that is to say when the end of the tigeron imbalances the kitten 20 out of its resting plane, the spring 10 cooperates with the complementary inclined planes 7, 7a; 8, 8a to refocus the kitten 20. Such bearings have for example been sold under the trademark Incabloc®. These springs can be made of phynox or brass and are manufactured by traditional means of cutting.

Or, un inconvénient de ces systèmes amortisseurs de chocs est que leur montage n'est pas aisé. En effet, certaines pièces comme le support 1 et le ressort 10 doivent être orientées et manipulées d'une certaine façon lors de l'opération de montage pour que l'assemblage puisse se faire. Ainsi, l'assemblage du système amortisseur de chocs commence en se munissant d'un support, puis d'un chaton avec ces pierres. Ce dernier est placé dans le logement du support. Ensuite, On se munit d'un ressort du type axial et qui présente une forme de lyre. Celui-ci est manipulé pour qu'il puisse prendre appui sous les retours des rebords semi-circulaires 11a, 11b du support.However, a disadvantage of these shock absorber systems is that their assembly is not easy. Indeed, certain parts such as the support 1 and the spring 10 must be oriented and manipulated in a certain way during the assembly operation so that the assembly can be done. Thus, the assembly of the shock absorber system begins by providing a support, then a kitten with these stones. The latter is placed in the support housing. Then, one is equipped with a spring of the axial type and which presents a form of lyre. It is manipulated so that it can take support under the returns of semicircular flanges 11a, 11b of the support.

Par conséquent, la mise en place du ressort et sa fixation au support nécessite une manipulation particulière. De ce fait, les systèmes amortisseurs de chocs doivent être assemblés en partie manuellement car un robot ne peut réaliser une manipulation si complexe.Therefore, the establishment of the spring and its attachment to the support requires special handling. As a result, the shock-absorbing systems must be assembled in part manually because a robot can not perform such complex manipulation.

De plus, l'assemblage manuel est privilégié car l'être humain est capable de savoir instantanément l'orientation dans laquelle il doit placer les pièces du système amortisseur de chocs les unes par rapport aux autres. En effet, peu importe la forme des pièces, l'homme est capable de savoir instantanément comme il doit manipuler ces pièces pour les assembler. Or, même si un robot peut distinguer l'orientation d'une pièce par rapport à une autre, cela nécessite un robot plus complexe et donc plus coûteux tout en nécessitant un temps plus important. Cela détériore en conséquence le rendement de production.In addition, the manual assembly is preferred because the human being is able to instantly know the orientation in which he must place the parts of the shock absorber system relative to each other. Indeed, regardless of the shape of the pieces, the man is able to know instantly how he must manipulate these pieces to assemble. However, even if a robot can distinguish the orientation of a room relative to another, it requires a more complex robot and therefore more expensive while requiring a longer time. This consequently deteriorates the production yield.

Ainsi, l'automatisation totale de l'assemblage n'est pas possible et le procédé d'assemblage des systèmes amortisseurs de chocs est donc plus coûteux.Thus, total automation of the assembly is not possible and the method of assembling the shock absorbing systems is therefore more expensive.

Par ailleurs, l'automatisation du montage peut entraîner la présence de vibrations qui se propagent au niveau du système amortisseur de chocs. Ces vibrations peuvent engendrer un déplacement des pièces du système amortisseur de chocs de sorte que ces pièces ne sont plus parfaitement centrées les unes par rapport aux autres. Ce décentrage potentiel peut entraîner d'autres dégâts. En effet, lors du montage d'une première pièce sur une seconde pièce, une troisième pièce devant être placée entre la première pièce et la seconde pièce peut se retrouver pincer par lesdites première et seconde pièces et ainsi être endommagée.Furthermore, the automation of the assembly can cause the presence of vibrations that propagate at the level of the shock absorber system. These vibrations can cause a displacement of the parts of the shock absorber system so that these parts are no longer perfectly centered relative to each other. This potential decentering can lead to further damage. Indeed, during the assembly of a first piece on a second piece, a third piece to be placed between the first piece and the second piece can be pinched by said first and second pieces and thus be damaged.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

La présente invention procède de l'idée générale inventive qui consiste à procurer un dispositif amortisseur de chocs non démontable ou système antichoc simple, facile à monter et offrant moins de risques de problèmes lors du montage. Ce système amortisseur de chocs est agencé pour être monté sur une platine et/ou au moins un pont d'un mouvement horloger. Le mouvement horloger est placé dans une pièce d'horlogerie comprenant une carrure fermée par un fond et une glace.The present invention proceeds from the general inventive idea of providing a non-removable shock absorbing device or simple shockproof system, easy to mount and offering less risk of problems during assembly. This shock absorber system is arranged to be mounted on a plate and / or at least one bridge of a movement watchmaker. The watch movement is placed in a timepiece comprising a middle part closed by a bottom and an ice.

Sur les figures 3 et 4, un dispositif ou palier amortisseur de chocs 100 ou système antichoc selon un premier mode de réalisation est représenté. Ce dispositif amortisseur de chocs ou système antichoc 100 est monté dans un élément de base d'un mouvement de pièce d'horlogerie. En particulier, la platine ou les ponts du mouvement sont l'élément de base dans lesquels le système antichoc 100 selon l'invention est placé. Ce système antichoc 100 comprend un support 200. Ce support 200 se présente sous la forme d'une coupelle 201, pourvue d'un trou 202, surmontée par un rebord périphérique 203 délimité, à l'opposé de ladite coupelle, par une surface supérieure 213. Ce rebord périphérique 203 présente également une paroi externe 214 et une paroi interne 215. Ce rebord 203 et la coupelle de fond 201 permettent de définir un logement 206 dans lequel un module pivot 400 est inséré. Un module pivot 400 classique comprend un chaton 401 c'est-à-dire une pièce présentant un orifice central circulaire, une paroi externe et une paroi interne. Dans l'orifice central est insérée une pierre percée 402 dont le diamètre correspond à celui de l'orifice central. La paroi interne comprend un épaulement de sorte qu'une pierre contre-pivot 403 puisse être fixée. Le module pivot 400 est alors placé dans le logement 206 du support 200 et coopère avec le tigeron d'un axe.On the figures 3 and 4 , a device or shock-absorbing bearing 100 or shockproof system according to a first embodiment is shown. This shock absorbing device or shockproof system 100 is mounted in a base element of a timepiece movement. In particular, the plate or the bridges of the movement are the basic element in which the anti-shock system 100 according to the invention is placed. This anti-shock system 100 comprises a support 200. This support 200 is in the form of a cup 201, provided with a hole 202, surmounted by a peripheral rim 203 delimited, opposite said cup, by an upper surface. 213. This peripheral flange 203 also has an outer wall 214 and an inner wall 215. This flange 203 and the bottom cup 201 define a housing 206 in which a pivot module 400 is inserted. A conventional pivot module 400 comprises a kitten 401, that is to say a part having a circular central orifice, an outer wall and an inner wall. In the central orifice is inserted a pierced stone 402 whose diameter corresponds to that of the central orifice. The inner wall includes a shoulder so that a counter pivot stone 403 can be attached. The pivot module 400 is then placed in the housing 206 of the support 200 and cooperates with the shank of an axis.

Le système antichoc 100 comprend en outre des moyens élastiques 300 qui sont agencés pour coopérer avec le module pivot 400. Cela permet d'amortir les chocs et de ramener le module pivot 400 dans sa position de repos lorsque les contraintes exercées suite aux chocs s'estompent. Les moyens élastiques 300 sont fixés sur le support 200. De préférence, les moyens élastiques 300 sont également placés sur le module pivot 400. Le système antichoc 100 est ensuite inséré dans un orifice de la platine ou dans l'un des ponts du mouvement.The shockproof system 100 further comprises resilient means 300 which are arranged to cooperate with the pivot module 400. This makes it possible to dampen the shocks and to bring the pivot module 400 back to its rest position when the stresses exerted following the shocks occur. fade. The elastic means 300 are fixed on the support 200. Preferably, the elastic means 300 are also placed on the pivot module 400. The shockproof system 100 is then inserted into an orifice of the plate or in one of the bridges of the movement.

Les moyens de fixation 500 comprennent une pièce supplémentaire 510 servant à fixer les moyens élastiques 300 sur le support 200. Cette pièce supplémentaire 510 se présente sous la forme d'un capot 510 qui se fixe sur le support 200. Ce capot 510 est conçu pour que lors de la fixation au support 200, les moyens élastique 300 exercent une contrainte sur le module pivot 400. Cette contrainte permet au module pivot 400 d'être immobile sans toutefois entraver le déplacement de celui-ci lors d'un choc. En effet, lors d'un choc, l'axe vient buter sur le module pivot 400 qui se déplace et déforme élastiquement les moyens élastiques 300.The attachment means 500 comprise an additional piece 510 for fixing the elastic means 300 on the support 200. This additional part 510 is in the form of a cover 510 which is fixed on the support 200. This cover 510 is designed to that during attachment to the support 200, the elastic means 300 exert a stress on the pivot module 400. This constraint allows the pivot module 400 to be stationary without, however, hinder the movement thereof during an impact. Indeed, during an impact, the axis abuts on the pivot module 400 which moves and elastically deforms the elastic means 300.

Ce capot 510 se présente sous la forme d'une pièce 511 présentant une ouverture 512. Cette pièce 511 présente une paroi intérieure 513 et une paroi extérieure 514 ainsi qu'une extrémité supérieure 515 et une extrémité inférieure 516. L'ouverture de l'élément 511 à une première dimension intérieure de sorte à coopérer avec le rebord périphérique 203. En effet, la pièce 511 se fixe via l'extrémité inférieure 515 au rebord périphérique 203. Ainsi, le support 20, le rebord 203 et le capot 510 peuvent être de forme carré ou avoir toutes autres formes possibles, il faut juste que l'élément 511 puisse se fixer au rebord périphérique 203This cover 510 is in the form of a part 511 having an opening 512. This part 511 has an inner wall 513 and an outer wall 514 and an upper end 515 and a lower end 516. The opening of the element 511 to a first inner dimension so as to cooperate with the peripheral rim 203. Indeed, the part 511 is fixed via the lower end 515 to the peripheral rim 203. Thus, the support 20, the rim 203 and the cover 510 can be of square shape or have any other possible forms, it is just necessary that the element 511 can be attached to the peripheral rim 203

Préférentiellement, le capot 510 se présente sous la forme d'une pièce 511 annulaire cylindrique s'étendant selon un axe central (C) et présentant une ouverture 512. Cette pièce 511 annulaire cylindrique présente une paroi intérieure 513 et une paroi extérieure 514 ainsi qu'une extrémité supérieure 515 et une extrémité inférieure 516. L'ouverture de la pièce 511 annulaire cylindrique à un premier diamètre intérieure D1 de sorte à coopérer avec le rebord périphérique 203. En effet, la pièce 511 annulaire cylindrique s'insère par l'extrémité inférieure 515 au rebord périphérique 203. Cette fixation de la pièce 511 annulaire cylindrique au rebord périphérique 203 se fait par insertion à force, par vissage, par soudage ou par collage.Preferably, the cap 510 is in the form of a cylindrical annular piece 511 extending along a central axis (C) and having an opening 512. This annular cylindrical piece 511 has an inner wall 513 and an outer wall 514 as an upper end 515 and a lower end 516. The opening of the cylindrical annular piece 511 to a first inner diameter D1 so as to cooperate with the peripheral rim 203. In fact, the annular cylindrical piece 511 is inserted by the lower end 515 to the peripheral rim 203. This attachment of the cylindrical annular piece 511 to the peripheral rim 203 is by force insertion, screwing, welding or gluing.

Une zone de maintien 520 est agencée sur la paroi intérieure 513. Cette zone de maintien 520 peut se présenter sous la forme d'une gorge 520a (non représentée) pour que les moyens élastiques 300 puissent s'y insérer. Cela permet aux moyens élastiques 300 de ne pas être pincés entre le capot 510 et le support 200 lors du montage du système antichoc 100. La paroi intérieure peut avoir une forme différente de la paroi extérieure 514, par exemple, la paroi intérieure 513 peut être circulaire et la paroi extérieure 514 peut être carré. De plus, il est envisageable que la paroi intérieure 513 présente une première forme au niveau de l'extrémité supérieure 515 et une seconde forme au niveau de l'extrémité inférieure 516. Ainsi, il est possible d'avoir une paroi intérieure 513 présentant, au niveau de son extrémité supérieure 515, une forme adapté pour la zone de maintien des moyens élastiques 300, et, au niveau de son extrémité inférieure 516, une forme adapté pour la fixation dudit capot 510 au support 200 via le rebord périphérique 203.A holding zone 520 is arranged on the inner wall 513. This holding zone 520 may be in the form of a groove 520a (not shown) so that the elastic means 300 can be inserted therein. This allows the elastic means 300 not to be pinched between the cover 510 and the support 200 during mounting of the shockproof system 100. The inner wall may have a different form of the outer wall 514, for example, the inner wall 513 may be circular and the outer wall 514 may be square. In addition, it is conceivable that the inner wall 513 has a first shape at the upper end 515 and a second shape at the lower end 516. Thus, it is possible to have an inner wall 513 having, at its upper end 515, a shape adapted for the holding region of the elastic means 300, and at its lower end 516, a shape adapted for fixing said cover 510 to the support 200 via the peripheral rim 203.

Dans une première variante avantageuse illustrée sur la figure 3, l'extrémité supérieure 515 de l'élément 511 annulaire cylindrique présente un second diamètre intérieur D2 plus faible que le premier diamètre intérieur D1. Cette différence de diamètre permet de créer une zone d'appui 517 pour les moyens élastiques 300. Au niveau de cette extrémité supérieure de la pièce 511 annulaire cylindrique présentant un second diamètre intérieur D2, la zone de maintien 520 est agencée.In a first advantageous variant illustrated on the figure 3 , the upper end 515 of the cylindrical annular element 511 has a second inner diameter D2 smaller than the first inner diameter D1. This difference in diameter makes it possible to create a bearing zone 517 for the elastic means 300. At this upper end of the cylindrical annular piece 511 having a second internal diameter D2, the holding zone 520 is arranged.

Cette zone de maintien 520 comprend une excroissance 521 s'étendant depuis la paroi intérieure 513 de la pièce 511 annulaire cylindrique. Cette excroissance 521 forme, avec la zone d'appui 517, une gorge 522 dans laquelle les moyens élastiques 300 s'insèrent. Les moyens élastiques 300 prennent appui sur l'excroissance 521. Lors d'un choc de la pièce d'horlogerie, l'axe vient buter sur le système antichoc 100 de sorte que le module pivot 400 se déplace. Les moyens élastiques 300 se déforment et viennent prendre appui sur la zone d'appui 517.This holding zone 520 comprises an outgrowth 521 extending from the inner wall 513 of the cylindrical annular piece 511. This protrusion 521 forms, with the bearing zone 517, a groove 522 in which the elastic means 300 fit. The elastic means 300 are supported on the protrusion 521. During an impact of the timepiece, the axis abuts on the shockproof system 100 so that the pivot module 400 moves. The elastic means 300 deform and come to bear on the bearing zone 517.

Les moyens élastiques 300 se présentent, par exemple, sous la forme d'un anneau ressort 301. Cet anneau ressort 301 est du type plat c'est-à-dire qu'il est constitué d'une bande ou ruban c'est-à-dire présentant une largeur plus grande que l'épaisseur. La bande ou ruban constituant l'anneau ressort 301 est métallique et circulaire s'étendant selon un axe central (C).The elastic means 300 are, for example, in the form of a spring ring 301. This spring ring 301 is of the flat type, that is to say that it consists of a band or ribbon that is that is, having a width greater than the thickness. The band or ribbon constituting the spring ring 301 is metallic and circular extending along a central axis (C).

Dans une première réalisation de cet anneau ressort 301 visible à la figure 5, les moyens élastiques 300 se présentent sous la forme d'un anneau ressort 301 qui comprend deux bras 302 s'étendant vers le centre axial dudit anneau ressort 301. Ces bras 302 sont diamétralement opposées et servent à plaquer ledit module pivot 400 dans le logement 206 du support 200.In a first embodiment of this spring ring 301 visible at the figure 5 , the elastic means 300 are in the form of a spring ring 301 which comprises two arms 302 extending towards the axial center of said spring ring 301. These arms 302 are diametrically opposed and serve to press said pivot module 400 into the housing 206 of the support 200.

Dans une seconde réalisation de cette anneau ressort 301 visible à la figure 6, l'anneau ressort 301 comprend des extensions radiales internes 303 disposées entre des parties annulaires 304. Ces extensions radiales internes 303 sont constituées par la bande formant l'anneau 301 qui est recourbée vers l'intérieur de l'anneau 301. Ces extensions radiales internes 303 sont, de préférence, régulièrement réparties sur le tour de l'anneau plat 301 de sorte que l'anneau ressort 301 puisse agir de façon homogène comme visible à la figure 5. On comprend alors que l'anneau ressort 301 peut être orienté d'une manière quelconque par rapport au support 200.In a second embodiment of this spring ring 301 visible at the figure 6 , the spring ring 301 comprises internal radial extensions 303 disposed between annular portions 304. These internal radial extensions 303 are constituted by the band forming the ring 301 which is curved towards the inside of the ring 301. These radial extensions 303 are preferably evenly distributed over the round of the flat ring 301 so that the spring ring 301 can act homogeneously as visible in the figure 5 . It is then understood that the spring ring 301 can be oriented in any way with respect to the support 200.

Cet anneau ressort 301 est alors agencé pour s'insérer dans la gorge 520a, 522 située sur la paroi intérieure 513 du capot 510. Plus particulièrement, ce sont les parties annulaires 303 qui s'insèrent dans ladite gorge 520a. Cette agencement permet d'avoir un anneau ressort 301 qui est solidaire du capot 510 c'est-à-dire que cet anneau ressort 301 est prémonté avec ledit capot 510. Ainsi, le montage dudit capot 510 est simplifié.This spring ring 301 is then arranged to fit into the groove 520a, 522 located on the inner wall 513 of the cover 510. More particularly, it is the annular portions 303 which fit into said groove 520a. This arrangement makes it possible to have a spring ring 301 which is integral with the cover 510, that is to say that this spring ring 301 is pre-assembled with said cover 510. Thus, the mounting of said cap 510 is simplified.

La gorge 520a, 522 présente des dimensions telles que l'anneau ressort 301, une fois installé, puisse légèrement se déplacer. Cela permet à l'anneau ressort 301 de se déplacer et de parfaitement se centrer lors du montage du capot 510 sur le support 200. Les vibrations pouvant être engendrées lors du montage automatique sont alors sans conséquence.The groove 520a, 522 has dimensions such that the spring ring 301, once installed, can move slightly. This allows the spring ring 301 to move and perfectly center when mounting the cap 510 on the support 200. The vibrations that can be generated during the automatic assembly are then of no consequence.

Dans une seconde variante, l'anneau ressort 301 présente, au niveau des parties annulaires 303, des ergots 305 s'étendant de sorte à s'éloigner du centre axial dudit anneau ressort 301 comme visible à la figure 7. Ces ergots 305 sont agencés pour maintenir ledit anneau ressort 301 audit capot 510. Effectivement, les dimensions de l'anneau ressort 301 et du capot 510 sont calculées de sorte que seuls les ergots 305 s'insèrent dans la gorge 520a.In a second variant, the spring ring 301 has, at the level of the annular portions 303, lugs 305 extending so as to move away from the axial center of said spring ring 301 as visible in FIG. figure 7 . These lugs 305 are arranged to maintain said spring ring 301 to said cover 510. Indeed, the dimensions of the spring ring 301 and the cap 510 are calculated so that only the lugs 305 fit into the groove 520a.

Cet agencement a l'avantage de permettre de limiter l'influence de la gorge 520a, 522 sur ledit anneau ressort 301. En effet, lorsque l'anneau ressort 301 est placé dans la gorge 520a, 522, cette dernière modifie la réponse mécanique lors d'une contrainte puisqu'elle exerce une contrainte sur ledit anneau ressort, notamment sur les parties annulaires 303 de l'anneau ressort 301 décrit auparavant. Ces parties annulaires 303 sont des zones actives c'est-à-dire qu'elles interviennent dans l'action élastique de l'anneau ressort 301. Les réactions dudit anneau ressort 301 peuvent alors être modifiées ce qui implique de les prendre en compte lors de la conception de l'anneau ressort 301.This arrangement has the advantage of making it possible to limit the influence of the groove 520a, 522 on said spring ring 301. Indeed, when the spring ring 301 is placed in the groove 520a, 522, the latter modifies the mechanical response during a constraint since it exerts a stress on said spring ring, in particular on the annular parts 303 of the spring ring 301 previously described. These annular portions 303 are active zones, that is to say they intervene in the elastic action of the spring ring 301. The reactions of said spring ring 301 can then be modified, which involves taking them into account when of the design of the spring ring 301.

Or, avec la présence des ergots 305, la contrainte exercée sur ledit anneau ressort 301 par la gorge 520a, 522 du capot 510 est uniquement localisée sur ces ergots 305. Par conséquent, comme ces ergots 305 sont des zones passives c'est-à-dire sans influence sur le comportement de l'anneau ressort 301. De ce fait, le comportement initial de l'anneau ressort 301 n'est pas modifié par son agencement dans la gorge 522, 520a du capot 510.However, with the presence of the pins 305, the stress exerted on said spring ring 301 by the groove 520a, 522 of the cover 510 is only located on these pins 305. Therefore, since these pins 305 are passive zones that is ie without influence on the behavior of the spring ring 301. As a result, the initial behavior of the spring ring 301 is not modified by its arrangement in the groove 522, 520a of the cover 510.

Dans une troisième variante, au moins le logement 206, le module pivot 400 et les moyens élastiques 300 sont réalisés/agencés pour que les différentes pièces soient angulairement libres les unes par rapport aux autres. On entend par là que les différentes pièces qui composent le système amortisseur de chocs 100 telle qu'au moins le logement 206, le module pivot 400 et les moyens élastiques 300 sont assemblées les unes dans les autres sans qu'une manipulation particulière soit nécessaire. Ainsi, aucune rotation ou manipulation ou torsion n'est faite lors du montage. Préférentiellement, au moins le logement 206, le module pivot 400, le capot 510 et les moyens élastiques 300 sont des pièces de révolution c'est-à-dire ayant une forme générale circulaire et s'étendant selon un axe central (C). Cette forme circulaire permet de s'adapter à toute les formes de support 200. Effectivement, la forme circulaire, sans orientation, du logement 206, du module pivot 400 et des moyens élastiques 300 permet d'avoir un support 200 de forme quelconque qui, lors du montage, sera positionné de façon quelconque sans que cela ait une incidence sur le processus de montage du palier amortisseur de chocs 100. Il est également possible que le support 200, le logement 206, le module pivot 400 et les moyens élastiques 300 sont des pièces de révolution c'est-à-dire ayant une forme circulaire.In a third variant, at least the housing 206, the pivot module 400 and the elastic means 300 are made / arranged so that the various parts are angularly free with respect to other. By this is meant that the various parts that make up the shock absorbing system 100 such that at least the housing 206, the pivot module 400 and the elastic means 300 are assembled into each other without any particular manipulation is necessary. Thus, no rotation or manipulation or twisting is made during assembly. Preferably, at least the housing 206, the pivot module 400, the cover 510 and the elastic means 300 are parts of revolution that is to say having a generally circular shape and extending along a central axis (C). This circular shape makes it possible to adapt to all the support forms 200. Indeed, the circular, non-oriented shape of the housing 206, the pivot module 400 and the elastic means 300 makes it possible to have a support 200 of any shape which, during assembly, will be positioned in any way without affecting the mounting process of the shock absorbing bearing 100. It is also possible that the support 200, the housing 206, the pivot module 400 and the elastic means 300 are parts of revolution that is to say having a circular shape.

Cette configuration des pièces du palier amortisseur de chocs 100 selon l'invention permet de faciliter l'assemblage. En effet, si les pièces présentent une orientation entre elles, il est nécessaire de les manipuler de sorte que l'assemblage puisse se faire. Par exemple, pour emboîter deux figures géométriques triangulaires l'une dans l'autres, il faut que chacun des cotés soient parallèles, une orientation est donc nécessaire.This configuration of the parts of the shock absorbing bearing 100 according to the invention facilitates assembly. Indeed, if the parts have an orientation between them, it is necessary to manipulate them so that the assembly can be done. For example, to fit two triangular geometric figures into each other, each side must be parallel, an orientation is necessary.

Or, en réalisant le support 200, le logement 206, le module pivot 400 et les moyens élastiques 300 de sorte que ces différentes pièces soient angulairement libres les unes par rapport aux autres, on permet de prendre, par exemple, le module pivot 400 et de le placer dans le logement 206 sans aucune manipulation préalable.However, by producing the support 200, the housing 206, the pivot module 400 and the elastic means 300 so that these different parts are angularly free with respect to each other, it is possible to take, for example, the pivot module 400 and to place it in the housing 206 without any prior manipulation.

On peut imaginer, le support 200 et l'élément du mouvement dans lequel le palier amortisseur de chocs 100 est placé ne sont qu'une seule et même pièce, le support 200 et l'élément du mouvement sont donc monoblocs. On comprend alors que l'élément de base présente un évidement agencé pour former un fond percé d'un trou et formant le logement 206 dans lequel le module pivot 400 est placé. On comprend également que cette seconde variante peut cohabiter avec la première variante. En effet, comme un pont ou une platine présente une forme quelconque, une zone de montage agencée permet d'être sure de pouvoir installer les moyens de fixations et donc de maintenir le module pivot 400 dans le logement.One can imagine, the support 200 and the element of the movement in which the shock absorbing bearing 100 is placed are only one and same piece, the support 200 and the element of movement are monobloc. It is then understood that the base member has a recess arranged to form a bottom pierced with a hole and forming the housing 206 in which the pivot module 400 is placed. It is also understood that this second variant can coexist with the first variant. Indeed, as a bridge or a platen has any shape, an assembly area arranged makes it possible to be sure to install the fastening means and thus to maintain the pivot module 400 in the housing.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.

En effet, il est possible que le module pivot 400 puisse être constitué d'une pierre unique ou que la pierre percée et la pierre contre-pivot soient solidaires l'une de l'autre. On comprend que la pierre percée et la pierre contre-pivot peuvent être chassées l'une dans l'autre ou être monoblocs. Ces possibilités permettent de limiter le nombre de pièce du palier amortisseur de chocs.Indeed, it is possible that the pivot module 400 may consist of a single stone or that the pierced stone and the pivot-pivot stone are integral with one another. It is understood that the pierced stone and the counter-pivot stone can be driven into one another or be one-piece. These possibilities make it possible to limit the number of parts of the shock-absorbing bearing.

De plus, on comprendra que la forme des moyens élastiques peut être envisageable pour peu qu'ils puissent s'insérer dans la gorge 520a, 522.In addition, it will be understood that the shape of the elastic means may be conceivable provided that they can fit into the groove 520a, 522.

On peut également imaginer que la capot 510 comprend deux gorges 520a, 522 afin de placer deux anneaux ressorts 301.One can also imagine that the cover 510 includes two grooves 520a, 522 to place two spring rings 301.
