Description

"ARTICULATION A ROTULE , AVEC AMORTISSEURS INTEGRES1 "BALL JOINT, WITH INTEGRATED SHOCK ABSORBERS 1
Le présente invention concerne une articu- lation à rotule , du genre de celles qu'on utilise pour as¬ surer , à la fois , l'accouplement et l'articulation de di¬ verses tringleries de commande ou de liaison.The present invention relates to a ball joint, of the kind used for ensuring, both, the coupling and the articulation of various control or linkage linkages.
De telles tringleries articulées par des rotules sont bien connues , d'une part sur des machines des types les plus divers,et d'autre part , dans l'automobile.Such linkages articulated by ball joints are well known, on the one hand on machines of the most diverse types, and on the other hand, in the automobile.
Actuellement , la plupart des articulations à rotule sont réalisées , comme décrit,par exemple, dans le brevet français 2 402 797 . Une telle articulation connue a pour avantage essentiel la possibilité de monter facilement sur la rotule ,1e boîtier d'articulation d'une tringlerie . Par ailleurs,1 ' articulation reste démontable,mais son démon¬ tage nécessite un effort beaucoup plus important .Ceci faci¬ lite le montage et accroît la fiabilité de l'ensemble. Le boîtier n'étant pas détérioré , il peut être réutilisé. out ceci réduit le coût et accroît la sécurité.Currently, most ball joints are made, as described, for example, in French patent 2,402,797. The essential advantage of such a known articulation is the possibility of easily mounting the articulation housing of a linkage on the ball joint. Furthermore, the articulation remains removable, but its dismantling requires a much greater effort. This facilitates mounting and increases the reliability of the assembly. The case is not damaged, it can be reused. all this reduces the cost and increases security.
Dans certains cas ,notamment pour des appli¬ cations dans l'automobile , il serait nécessaire d'interpo¬ ser,entre le levier de commandes et la boîte à vitesses ,un système d'amortissement ,qui aurait pour but de réduire le bruit ou les vibrations.In certain cases, in particular for applications in the automobile, it would be necessary to interpose, between the control lever and the gearbox, a damping system, which would have the aim of reducing noise or vibrations.
Pour parvenir à ce résultat ,une solution connue consiste à interposer une pièce complémentaire ,mu¬ nie d'un silent-block élastique.Cette solution connue per¬ met d'obtenir le résultat souhaité en ce qui concerne 1 ' a- ortissement du bruit et des vibrations , mais elle est coû¬ teuse et offre plusieurs inconvénients , notamment :To achieve this result, a known solution consists in interposing an additional part, provided with an elastic silent block. This known solution allows the desired result to be obtained with regard to noise abatement. and vibrations, but it is costly and offers several disadvantages, in particular:
- articulation dans un seul plan ;- articulation in a single plane;
- rajout obligatoire d'un système de blocage , pour éviter le désemmanchement , après montage de 1 ' rti- culation sur l'axe de rotation ;- mandatory addition of a blocking system, to avoid undocking, after mounting the cross-link on the axis of rotation;
- rajout d'une bague intermédiaire pour permet¬ tre le montage de 1 ' amortisseur sur la biell.ette de trin¬ glerie;- addition of an intermediate ring to allow mounting of the damper on the connecting rod;
- fi on constate qu'en utilisation , ce système connu est peu fiable , car il se produit une corrosion et éventuellement un, grippage , entre l'axe de rota¬ tion et la bague intérieure de l'amortisseur ( ce qui nuit au bon fonctionnement de l'articulation).. La présente invention a pour but d'évi¬ ter ces inconvénients , en réalisant une articulation a rotu¬ le d'un type nouveau , comportant un amortisseur élastique intégré.- fi it is found that in use, this known system is not very reliable, because corrosion and possibly a seizure between the axis of rotation and the inner ring of the shock absorber (which affects the proper functioning of the joint). The present invention aims to avoid these drawbacks, by realizing a new type of articulation with a built-in elastic damper.
Une articulation à rotule perfectionnée selon l'invention , comprend un palier sphérique en matière moulée et monté dans un boîtier rigide , si bien que 1 ' assem¬ blage s'effectue par clipsage à force d'une rotule mâle dans le palier , et elle est caractérisée en ce que le boîtier est entouré par un amortisseur en matière élastique dont il est solidaire , cet amortisseur étant lui-même fixé par sa périphérie , dans un manchon de support.An improved ball joint according to the invention comprises a spherical bearing of molded material and mounted in a rigid housing, so that the assembly is effected by clipping by force of a male ball joint in the bearing, and it is characterized in that the housing is surrounded by a shock absorber of elastic material to which it is integral, this shock absorber itself being fixed by its periphery, in a support sleeve.
Suivant une autre caractéristique de 1 ' invention , l'amortisseur est constitué par un anneau en ca¬ outchouc ou analogue , surmoulé d'une part sur l'extérieur du boîtier qu'il entoure , d'autre part sur l'intérieur du manchon de support.According to another characteristic of the invention, the damper is constituted by a rubber ring or the like, molded on the one hand on the outside of the housing which it surrounds, on the other hand on the inside of the sleeve. of support.
Suivant une autre caractéristique de 1 ' invention , l'amortisseur élastique a une forme annulaire dans laquelle sont répartis des alvéoles de déformation . Suivant une autre caractéristique de 1* invention ,1a périphérie du palier peut coulisser à l'inté¬ rieur du boîtier , à 1'encontre d'une rondelle élastique prenant appui sur le boîtier , sous le fond du palier .According to another characteristic of one invention, the elastic damper has an annular shape in which are distributed deformation cells. According to another characteristic of the invention, the periphery of the bearing can slide inside the housing, against an elastic washer bearing on the housing, under the bottom of the bearing.
Suivant une autre caractéristique de 1 ' invention , le palier est pourvu d'une fente intéressant toute sa hauteur , afin de faciliter sa déformation , lors¬ qu'on emmanche la rotule.According to another characteristic of the invention, the bearing is provided with a slit covering its entire height, in order to facilitate its deformation, when the ball joint is engaged.
Le dessin annexé , donné à titre d'exem¬ ple non limitatif , permettra de mieux comprendre les carac- téristiques de l'invention , et les avantages qu'elle est sussceptible de procurer.The appended drawing, given by way of nonlimiting example, will make it possible to better understand the characteristics of the invention, and the advantages which it is likely to provide.
Figures 1 à 4 sont des perspectives en coupe , illustrant les phases successives pour la fabrica¬ tion du boîtier à amortisseur incorporé selon l'invention. Figures 5 à 7 illustrent les opérations d'assemblage d'une articulation à rotule selon l'inven¬ tion.Figures 1 to 4 are sectional views, illustrating the successive phases for the manufacture of the housing with built-in damper according to the invention. Figures 5 to 7 illustrate the operations assembly of a ball joint according to the invention.
On a représenté sur la figure 1 , un manchon de support métallique 1 , auquel est latéralement soudée une barre métallique 2 . A 1 ' intérieur du manchon 1 , se trouve un boîtier 3 dont il est rendu définitive¬ ment solidaire par surmoulage , collage , vulcanisation ou autre , d'un amortisseur 4 en une matière souple tel- le qu'un caoutchouc ou une matière plastique.FIG. 1 shows a metal support sleeve 1, to which a metal bar 2 is laterally welded. Inside the sleeve 1, there is a housing 3 which is made definitively integral by overmolding, bonding, vulcanization or the like, of a shock absorber 4 made of a flexible material such as rubber or plastic .
Le manchon 1 a la forme d'un tronçon d' un tube cylindrique de révolution.The sleeve 1 has the shape of a section of a cylindrical tube of revolution.
Le boîtier 3 , lui aussi de forme tubu- laire , présente , à sa partie inférieure , un tronc de cône rétreint 5 . Sa partie supérieure cylindrique 6 dé¬ passe preferablement au-dessus du manchon 1.The casing 3, also of tubular shape, has, at its lower part, a constricted truncated cone 5. Its cylindrical upper part 6 preferably passes over the sleeve 1.
L'amortisseur 4 occupe l'espace inter¬ médiaire annulaire , situé entre le manchon 1 et le boî¬ tier 3 . Il est preferablement creusé d'alvéoles 7 , 8 , dont le nombre , la forme et la répartition peuvent être choisis en fonction des caractéristiques élastiques et d' amortissement désirées .The damper 4 occupies the annular intermediate space, located between the sleeve 1 and the housing 3. It is preferably hollowed out of cells 7, 8, the number, shape and distribution of which can be chosen as a function of the elastic and damping characteristics desired.
De haut en bas ( figure 2 , flèche 9), on introduit , dans le boîtier 3 , un palier sphérique 10 dont le logement sphérique 11 est ouvert vers le bas . Son fond supérieur plat 12 se trouve donc au-dessous de la partie supérieure 6 , tandis que son nez tronconique 13 revient s'encastrer dans le tronc de cône rétreint 5 où il reste tendu . Ce palier 10 est réalisé en une matière synthétique connue , telle que , par exemple , une super¬ polyamide . Il présente la particularité d'être latérale¬ ment fendu suivant une fente 14 qui traverse toute l'épais¬ seur de sa paroi. La fente 14 est preferablement oblique ou hélicoïdale . Enfin , le diamètre 15 de l'ouverture du logement 11 est inférieur au diamètre 16 de ce logement sphérique (figure 3) .From top to bottom (Figure 2, arrow 9), a spherical bearing 10 is introduced into the housing 3, the spherical housing 11 of which is open downwards. Its flat upper bottom 12 is therefore located below the upper part 6, while its frustoconical nose 13 returns to be embedded in the constricted truncated cone 5 where it remains taut. This bearing 10 is made of a known synthetic material, such as, for example, a polyamide super¬. It has the particularity of being laterally split along a slot 14 which crosses the entire thickness of its wall. The slot 14 is preferably oblique or helical. Finally, the diameter 15 of the opening of the housing 11 is less than the diameter 16 of this spherical housing (Figure 3).
Grâce à cette fente 14 , le palier 10 présente une déformabilité supérieure à ce que permet¬ trait seule la nature de sa matière constitutive. Sur le fond 12 , on pose un ressort plat 17 , par exemple du type dit " rondelle papillo ".Thanks to this slot 14, the bearing 10 has a greater deformability than that allows only the nature of its constituent material. On the bottom 12, we put a spring flat 17, for example of the so-called "papillo washer" type.
On sait qu'un tel ressort comporte , sur sa périphérie , de larges ailes découpées alternativement inclinées vers le haut ( ailes 18) et vers le bas ( ailes 19) . Ainsi , les ailes inférieures 19 prennent appui sur le fond 12 , cependant que les ailes supérieures 18 restent dirigées vers le haut , contre la paroi interne de la partie supé¬ rieure 6 ( figure 3). On roule cette dernière vers 1 ' inté¬ rieur et vers le bas (figure 4 ,flèche 20) , jusqu'à ve¬ nir comprimer le sommet des ailes 18 au-dessus desquelles est ainsi formée une collerette de compression 21.It is known that such a spring has, on its periphery, large cut wings alternately inclined upwards (wings 18) and downwards (wings 19). Thus, the lower wings 19 are supported on the bottom 12, while the upper wings 18 remain directed upwards, against the internal wall of the upper part 6 (Figure 3). The latter is rolled inwards and downwards (FIG. 4, arrow 20), until ve¬ nir compress the top of the wings 18 above which a compression flange 21 is thus formed.
Le logement 11 est prévu pour rece- voir une rotule sphérique mâle 22 , solidaire d'une tige métallique 23 . Le diamètre 24 de la rotule 22 est sensi¬ blement égal au diamètre 16 du palier 13 au repos.The housing 11 is designed to receive a male spherical ball joint 22, integral with a metal rod 23. The diameter 24 of the ball joint 22 is substantially equal to the diameter 16 of the bearing 13 at rest.
Le fonctionnement est le suivant: Pour mettre en place la rotule 22 , on la présente sous l'ouverture du logement 11 (figure 5) puis on l'y enfonce à force ( figure 6 , flèche 25) .The operation is as follows: To set up the ball joint 22, it is presented under the opening of the housing 11 (FIG. 5) and then it is forced into it (FIG. 6, arrow 25).
Ce faisant , par écrasement du res¬ sort 17 entre la collerette 21 et le fond plat 12 , on provoque la remontée du palier 13 par coulissement dans le boîtier 3 . Il en résulte que le nez tronconique 13 est extrait vers le haut hors du tronc de cône rétreint 5 où il était encastré , si bien que , désormais , la fente 14 peut s'élargir et bailler jusqu' à laisser la sphère 22 franchir l'entrée resserrée du logement 11. Une fois la rotule 22 en place dans ce logement ( figure 7 ) , 1 ' assemblage est terminé ; la barre 2 et la tige 23 sont désormais reliées par une ar¬ ticulation à rotule . Le ressort 17 rappelle élastiquement vers le bas le palier 10 dont le nez est à nouveau serré et encastré dans le tronc de cône rétreint 5.In doing so, by crushing the res¬ fate 17 between the flange 21 and the flat bottom 12, the bearing 13 is raised by sliding in the housing 3. As a result, the frustoconical nose 13 is extracted upwards from the constricted truncated cone 5 where it was embedded, so that, from now on, the slot 14 can widen and yawn until letting the sphere 22 cross the tight entry of the housing 11. Once the ball 22 in place in this housing (Figure 7), 1 assembly is completed; the bar 2 and the rod 23 are now connected by a ball joint. The spring 17 resembles the bearing 10 elastically downwards, the nose of which is again tightened and embedded in the constricted truncated cone 5.
Parmi les avantages de cette articu¬ lation ,on peut noter que :Among the advantages of this articulation, it can be noted that:
- les organes 5 , 13 , 17 suffisent à eux seuls pour empêcher tout arrachement intempestif de la rotu- le 22 hors de son palier 13 ;the members 5, 13, 17 are sufficient in themselves to prevent any untimely tearing of the ball 22 out of its bearing 13;
FEUILLE DE REMPLACEMENT - aucun système de blocage complémentaire n' est nécessaire ;REPLACEMENT SHEET - no additional blocking system is necessary;
- aucune bague intermédiaire n'est nécessaire du genre de celles dont on sait qu'elles engendrent des problèmes de corrosion dans les articulations connues ;- No intermediate ring is necessary of the kind which are known to cause corrosion problems in known joints;
- la fente 14 peut travailler , c'est-à-dire bailler plus ou moins quand la matière vieillit : ce- la évite donc au palier 13 de risquer , à la longue, un serrage sur la rotule 22 , ce qui aurait pour ré¬ sultat néfaste de faire tourner la palier 13 dans le boîtier 3 ;- The slot 14 can work, that is to say yawning more or less when the material ages: this therefore avoids the bearing 13 from risking, in the long run, a tightening on the ball 22, which would have for re ¬ harmful result of rotating the bearing 13 in the housing 3;
- le ressort métallique 17 peut résister à des températures élevées , et il constitue un écran ther¬ mique protecteur pour le fond 12 du palier 13 . - the metal spring 17 can withstand high temperatures, and it constitutes a protective thermal screen for the bottom 12 of the bearing 13.
