Rotule élastique d'articulation et procédé de montage~d'une telle rotule
La présente invention concerne une rotule élastique d'articulation ainsi que son procédé de montage.Elastic articulation ball joint and method of mounting ~ such a ball joint
The present invention relates to an elastic articulation ball and its mounting method.
Les rotules élastiques d'articulation sont généralement constituées d'une armature intérieure, cette armature comportant une calotte sphérique, un alésage pour recevoir un axe, ou des embouts adaptés pour permettre un montage en chape, d'une bague externe munie d'une cavité sphérique, et d'un élément amortisseur en caoutchouc naturel ou synthétique moulé entre l'armature et la bague externe. The elastic articulation ball joints generally consist of an internal reinforcement, this reinforcement comprising a spherical cap, a bore to receive an axis, or end pieces adapted to allow a mounting in clevis, of an external ring provided with a cavity spherical, and a damping element in natural or synthetic rubber molded between the frame and the outer ring.
D'une manière connue, la bague externe de certaines rotules est constituée de deux demi-bagues, munie chacune d'une cavité interne demi-sphérique, reliées entre elles par un plan de joint radial et maintenues par une douille recouvrant les deux demi-bagues. En ce qui concerne le montage de ce type de rotules, la douille est ajustée sur les deux demi-bagues et chaque extrémité de cette douille est alors repliée et matée pour maintenir les demi-bagues serrées l'une contre l'autre au niveau du plan de joint. Au cours de ce montage, en amenant les deux demi-bagues en contact par un effort axial, on introduit inévitablement des contraintes de cisaillement dans l'élément amortisseur et de plus, les contraintes de compression ne sont pas uniformes. In a known manner, the outer ring of certain ball joints consists of two half-rings, each provided with a semi-spherical internal cavity, connected together by a radial joint plane and held by a sleeve covering the two half-rings. rings. As regards the mounting of this type of ball joint, the bush is adjusted on the two half-rings and each end of this bush is then folded and matted to keep the half-rings tight against each other at the level of the joint plane. During this assembly, by bringing the two half-rings into contact by an axial force, shear stresses are inevitably introduced into the damping element and, moreover, the compression stresses are not uniform.
Elles sont plus importantes aux bords qu'au centre de la rotule. La durée de vie de cette rotule s'en trouve alors limitée.They are more important at the edges than in the center of the patella. The life of this ball joint is therefore limited.
La présente invention a pour but de supprimer les contraintes de cisaillement introduites lors du montage et de répartir uniformément les contraintes de compression. The object of the present invention is to eliminate the shear stresses introduced during assembly and to uniformly distribute the compression stresses.
Elle a pour objet une rotule élastique d'articulation, constituée d'une armature interne comportant dans sa partie centrale une calotte sphérique, d'un élement amortisseur moulé recouvrant entièrement la calotte sphérique, de deux demi-bagues raccordées par un plan de joint radial et munies chacune d'une cavité-demi-sphérique, caractérisée en ce qu'elle comporte deux demi-coquilles souples raccordées par un plan de joint axial et situées entre l'élément amortisseur et les deux demi-bagues. Its subject is an elastic articulation ball joint, consisting of an internal frame comprising in its central part a spherical cap, a molded damping element entirely covering the spherical cap, two half-rings connected by a radial joint plane and each provided with a semi-spherical cavity, characterized in that it comprises two flexible half-shells connected by an axial joint plane and situated between the damping element and the two half-rings.
Avantageusement au niveau du contact entre les deux demi-bagues et les deux demi-coupelles, le rayon de la cavité demi-spérique de chaque demi-bague est légèrement inférieur au rayon sphérique extérieur de chaque demi-coupelle pour apporter une précontraite de l'élément amortisseur. Advantageously, at the level of the contact between the two half-rings and the two half-cups, the radius of the semi-spherical cavity of each half-ring is slightly less than the external spherical radius of each half-cup to provide a pre-tension of the damping element.
Elle a également pour objet un procédé de montage de cette rotule, caractérisé en ce que, après moulage de l'élément amortisseur entre l'armature et les deux demi-coquilles, on introduit axialement les deux demi-bagues sur la rotule pour les amener au contact l'une de l'autre, et on les maintient en contact par des moyens appropriés. It also relates to a method of mounting this ball joint, characterized in that, after molding the damping element between the frame and the two half-shells, the two half-rings are introduced axially on the ball joint to bring them in contact with each other, and they are kept in contact by appropriate means.
Selon un mode préféré de montage, on sertit les extrémités des deux demi-coquilles sur chaque demi-bague. According to a preferred mounting method, the ends of the two half-shells are crimped onto each half-ring.
Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, une rotule selon l'invention. There is described below, by way of example and with reference to the accompanying drawings, a ball joint according to the invention.
La figure 1 montre, en coupe axiale suivant I de la figure 2, une rotule selon l'invention. Figure 1 shows, in axial section along I of Figure 2, a ball joint according to the invention.
La figure 2 montre la rotule en demi-vue, demi-coupe suivant II de la figure 1. FIG. 2 shows the ball joint in half-view, half-section along II of FIG. 1.
Dans la figure 1, il est représenté une rotule 1 constituée d'une armature interne 2, d'un élément amortisseur 3 de deux demi-coquilles 4, 4', et de deux demi-bagues externes 6, 6'. In Figure 1, there is shown a ball 1 consisting of an internal frame 2, a damping element 3 of two half-shells 4, 4 ', and two external half-rings 6, 6'.
L'armature interne 2 comporte une calotte sphérique 2' et omette armature est creuse pour recevoir un axe, mais elle peut également être pleine et munie d'embouts appropriés pour un montage en chape. The internal frame 2 comprises a spherical cap 2 ′ and omits the frame is hollow to receive an axis, but it can also be full and provided with suitable end caps for mounting in a yoke.
Les deux demi-coquilles 4, 4' sont souples, réalisées de préférence en tôle emboutie, et elles comportent un plan de joint axial mieux visible en figure 2. Ces deux demi-coquilles sont recouvertes par les deux demi-bagues externes 6, 6' qui comportent un plan de joint radial. The two half-shells 4, 4 ′ are flexible, preferably made of stamped sheet metal, and they have an axial joint plane better visible in FIG. 2. These two half-shells are covered by the two external half-rings 6, 6 'which have a radial joint plane.
Chaque demi-bague 6, 6' comporte un épaulement interne 7, 7' et les extrémités 5, 5' de chaque demi-coquille 4, 4' sont serties chacune sur un épaulement 7, 7'. Each half-ring 6, 6 'has an internal shoulder 7, 7' and the ends 5, 5 'of each half-shell 4, 4' are each crimped on a shoulder 7, 7 '.
Le moulage de l'élément amortisseur 3 s'effectue entre l'armature 2 et les deux demi-coquilles 4, 4'. Le retrait du caoutchouc est facilité du fait de la présence des deux demi-coquilles, et ce retrait n'introduit pas de contraintes de traction au niveau de l'adhérisa tion. The damping element 3 is molded between the frame 2 and the two half-shells 4, 4 '. The withdrawal of the rubber is facilitated due to the presence of the two half-shells, and this withdrawal does not introduce tensile stresses at the level of the adhesion.
Une opération de montage s'effectue de la manière suivante après moulage de l'élément amortisseur, on introduit les deux demi-bagues sur les deux demi-coquilles et ces deux demi-bagues permettent d'apporter une précontrainte de l'élément amortisseur, car le rayon sphérique de chaque demi-bague est légèrement inférieur au rayon sphérique de chaque demi-coupelle. Lorsque les deux bagues sont en place, on sertit les extrémités 5, 5' de chaque demi-coupelle 4, 4' et on maintient ainsi la précontrainte de l'élément amortisseur. An assembly operation is carried out in the following manner after molding of the damping element, the two half-rings are introduced on the two half-shells and these two half-rings make it possible to provide a prestressing of the damping element, because the spherical radius of each half-ring is slightly less than the spherical radius of each half-cup. When the two rings are in place, the ends 5, 5 ′ of each half-cup 4, 4 ′ are crimped and the preload of the damping element is thus maintained.
L'effort nécessaire au maintien des deux bagues est moins important que celui qui est appliqué à l'élément amortisseur. L'opération de sertissage peut bien entendu être remplacée par des moyens équivalents par exemple, par la mise en place d'un circlips ou d'un jonc sur les extrémités de demi-coupelles, munies d'une gorge appropriée, et chaque demi-bague 6, 6' prend alors appui par l'intermédiaire -de son épaulement 7, 7' sur un circlips ou un jonc. The effort required to maintain the two rings is less than that applied to the damping element. The crimping operation can of course be replaced by equivalent means for example, by placing a circlip or a ring on the ends of half-cups, provided with an appropriate groove, and each half ring 6, 6 'then bears via its shoulder 7, 7' on a circlip or a ring.
Ce montage avec précontrainte permet une meilleure répartition des contraintes de compression. La rotule 1 ainsi montée, est une pièce finie qui ne nécessite pas un usinage de son diamètre extérieur. This pre-stressed mounting allows a better distribution of the compression stresses. The ball joint 1 thus mounted, is a finished part which does not require machining of its outside diameter.
