Description

Palier d'embrayage à centrage automatique ". Self-centering clutch bearing ".

La présente invention a pour objet un palier à centrage automatique, permettant notamment de débrayer des embrayages d'automobiles de tourisme. The present invention relates to a self-centering bearing, allowing in particular to disengage clutches of passenger cars.

A l'heure actuelle, les paliers d'embrayage sont munis de joints d'étanchéité en caoutchouc du côté de l'embrayage et de déflecteurs en tôle du côté opposé qui sont moins soumis aux effets de la poussière ambiante. Dans le but d'assurer un frottement uniforme pendant le déplacement du palier dans le sens radial, et de compenser les écarts angulaires pendant la transmission de la force de débrayage entre la membrane, le palier et la surface d'appui de la bride du porte-butee, on insère, assez souvent, un anneau d'appui en plastique entre le palier ou éventuellement sa bague non rotative, et la surface d'appui de la bride du porte-butée.Cependant, cette version de palier à centrage automatique présente l'inconvénient de diviser l'élément d'étanchéité et d'appui en deux composants indépendants, de prévoir nécessairement une gorge pour joint d'étanchéité dans la bague extérieure du palier et d'exiger un espace assez vaste. At present, clutch bearings are fitted with rubber seals on the clutch side and sheet metal deflectors on the opposite side which are less subject to the effects of ambient dust. In order to ensure a uniform friction during the displacement of the bearing in the radial direction, and to compensate for the angular deviations during the transmission of the declutching force between the membrane, the bearing and the bearing surface of the door flange -stop, quite often a plastic support ring is inserted between the bearing or possibly its non-rotating ring, and the support surface of the flange of the stopper.However, this version of self-centering bearing has the disadvantage of dividing the sealing and supporting element into two independent components, of necessarily providing a groove for a seal in the outer ring of the bearing and of requiring a fairly large space.

La présente invention a pour but de créer un palier d'embrayage à centrage automatique qui remédie à ces inconvénients.  The object of the present invention is to create a self-centering clutch bearing which overcomes these drawbacks.

A cet effet, l'invention concerne un palier caractérisé en en ce que l'anneau d'appui est réalisé sous la forme d'un disque plan muni d'un alésage dont le diamètre extérieur est avantageusement moins grand que celui de la bague extérieure du palier, ce disque étant muni, du côté frontal par rapport au palier, d'un anneau de section avantageusement rectangulaire, cet anneau présentant un diamètre extérieur aussi grand que celui de l'épaulement de la bague extérieure du palier ou dépassant celui-ci de la valeur de la saillie. To this end, the invention relates to a bearing, characterized in that the support ring is produced in the form of a flat disc provided with a bore whose outside diameter is advantageously less than that of the outer ring. of the bearing, this disc being provided, on the front side with respect to the bearing, of a ring of advantageously rectangular section, this ring having an outside diameter as large as that of the shoulder of the outer ring of the bearing or projecting therefrom the value of the projection.

Selon une autre caractéristique de l'invention, le diamètre intérieur de l'anneau d'appui est moins grand que celui de la bague intérieure du palier. Selon une autre caractéristique de l'invention, le diamètre intérieur de l'anneau est plus grand que le diamètre de l'épaulement de la bague intérieure du palier. Selon une autre caractéristique encore de l'invention, la bague intérieure du palier est munie de dégagement du côté de la bride du porte-butée. Une autre substance de l'invention consiste en ce que le diamètre intérieur de l'anneau est moins grand que le diamètre de l'épaulement de la bague intérieure du palier. Une autre substance de l'invention consiste en ce que l'anneau est muni de creux, celui-ci, orienté dans le sens axial, est réalisé comme une rainure continue ou entrecoupée de proéminences disposées dans des intervalles réguliers. According to another characteristic of the invention, the internal diameter of the support ring is less than that of the internal ring of the bearing. According to another characteristic of the invention, the inner diameter of the ring is larger than the diameter of the shoulder of the inner ring of the bearing. According to yet another characteristic of the invention, the inner ring of the bearing is provided with clearance on the side of the flange of the stop carrier. Another substance of the invention consists in that the internal diameter of the ring is less than the diameter of the shoulder of the internal ring of the bearing. Another substance of the invention consists in that the ring is provided with recesses, the latter, oriented in the axial direction, is produced as a continuous groove or interspersed with prominences arranged in regular intervals.

La forme préférée de réalisation du palier d'embrayage à centrage automatique selon l'invention consiste notamment en ce que l'anneau d'appui exerce, en même temps, la fonction de déflecteur, en facilitant ainsi sensiblement le montage du palier et en évitant la nécessité de former la gorge de fixation du déflecteur dans la bague extérieure du palier. Compa rativement à la version classique des joints d'étan cheité de'palier, l'application de l'anneau d'appui permet d'augmenter l'effet d'étanchéité dit à "labyrinthe", de remplir en même temps, l'espace du palier d'un plus grand volume de lubrifiant, et éventuellement d'utiliser une boite en matière plastique massive. The preferred embodiment of the self-centering clutch bearing according to the invention consists in particular in that the support ring exerts, at the same time, the deflector function, thereby appreciably facilitating the mounting of the bearing and avoiding the need to form the deflector fixing groove in the outer ring of the bearing. Compared to the classic version of the seals of the staircase, the application of the support ring makes it possible to increase the sealing effect called "labyrinth", to fill at the same time, the bearing space with a larger volume of lubricant, and possibly using a massive plastic box.

L'invention sera mieux comprise à la lecture de la description détaillée qui suit du palier d'embrayage à centrage automatique, donnée à titre d'exemple en se référant aux dessins annexés, dans lesquels - la figure 1 représente la version de base ; et - la figure 2 représente une autre version possible dudit palier. The invention will be better understood on reading the detailed description which follows of the self-centering clutch bearing, given by way of example with reference to the appended drawings, in which - FIG. 1 represents the basic version; and - Figure 2 shows another possible version of said bearing.

La figure 1 est une vue représentant un palier d'embrayage à centrage automatique comportant un porte-butée 4 sur lequel le palier est monté par sa bague intérieure 5, avec un jeu radial, ce palier comportant entre sa bague extérieure 2 et la bride du porte-butée 4 un anneau d'appui 1 en matière plastique se présentant sous la forme d'un disque plan muni d'un alésage. Le diamètre extérieur de l'anneau d'appui 1 est moins grand que celui de la bague extérieure 2 du palier, le diamètre intérieur de l'anneau d'appui 1 étant moins grand que celui de la bague intérieure 5 du palier. La face frontale de l'anneau d'appui 1 est constituée, du côté du palier, par un anneau 3 de section rectangulaire disposé de manière à présenter une saillie dans l'épaulement de la bague extérieure 2 du palier.Le diamètre intérieur de l'anneau 3 est plus grand que le diamètre de l'épaulement de la bague intérieure 5 du palier. Figure 1 is a view showing a self-centering clutch bearing comprising a bearing carrier 4 on which the bearing is mounted by its inner ring 5, with a radial clearance, this bearing comprising between its outer ring 2 and the flange of the abutment holder 4 a support ring 1 made of plastic material in the form of a flat disc provided with a bore. The outer diameter of the support ring 1 is less than that of the outer ring 2 of the bearing, the inner diameter of the support ring 1 being less than that of the inner ring 5 of the bearing. The front face of the support ring 1 is constituted, on the side of the bearing, by a ring 3 of rectangular section arranged so as to present a projection in the shoulder of the outer ring 2 of the bearing. The inside diameter of l 'ring 3 is larger than the diameter of the shoulder of the inner ring 5 of the bearing.

La figure 2 représente une version de l'anneau d'appui 1 dans laquelle cet anneau est également monté par l'intermédiaire de l'anneau. 3 dans la bague extérieure 2 du palier. Le diamètre intérieur de l'anneau 3 est moins grand que le diamètre de l'épaulement de la bague intérieure 5 du palier. De ce fait, l'anneau 3 s'engrène avec jeu dans le dégagement rectangulaire 6 ménagé dans la bague intérieure 5 du palier. L'anneau 3 est également muni d'un creux axial 7 qui, dans ce cas représenté ici, se présente sous la forme d'une rainure continue de section rectangulaire. FIG. 2 represents a version of the support ring 1 in which this ring is also mounted by means of the ring. 3 in the outer ring 2 of the bearing. The inner diameter of the ring 3 is less than the diameter of the shoulder of the inner ring 5 of the bearing. Therefore, the ring 3 meshes with play in the rectangular clearance 6 formed in the inner ring 5 of the bearing. The ring 3 is also provided with an axial recess 7 which, in this case shown here, is in the form of a continuous groove of rectangular section.

Dans ce cas particulier, le creux 7 peut être entrecoupé de proéminences disposées à intervalles réguliers ou, éventuellement, de nervures orientées dans le sens radial.In this particular case, the hollow 7 may be interspersed with prominences arranged at regular intervals or, possibly, ribs oriented in the radial direction.

Pendant le fonctionnement du palier d'embrayage à centrage automatique selon l'invention, le porte- butée 4 est réglé par un levier de débrayage non représenté et fait appuyer la bague intérieure 5 du palier sur le ressort Belleville de l'embrayage, ce qui provoque son mouvement de rotation. Lorsqu'on appuie pour la première fois sur la pédale d'embrayage après le montage du moteur, de l'embrayage et de la boîte de vitesses, le palier s'installe, par rapport au porte-butée 4 dans une position coaxiale ou .non coaxiale suivant la précision de position du moteur par rapport à la boîte de vitesses, ce qui est accompagné du déplacement radial non seulement du palier, mais aussi de l'anneau d'appui 1. En plus de sa fonction d'élément d'appui, l'anneau 3 sert également de déflecteur dont l'effet d'étanchéité à labyrinthe est augmenté par le creux 7. Dans le cas du déplacement radial maximum du palier par rapport au porte-butee 4, l'anneau d'appui 1 évite le contact de la bague intérieure 5 rotative du palier avec la surface extérieure du moyeu du porte-butée 4.  During the operation of the self-centering clutch bearing according to the invention, the thrust bearing 4 is adjusted by a disengaging lever not shown and causes the inner ring 5 of the bearing to rest on the Belleville spring of the clutch, which causes its rotational movement. When the clutch pedal is pressed for the first time after the engine, clutch and gearbox have been fitted, the bearing is installed, with respect to the stopper holder 4 in a coaxial position or. non-coaxial depending on the position accuracy of the motor with respect to the gearbox, which is accompanied by the radial displacement not only of the bearing, but also of the support ring 1. In addition to its function as an element of support, the ring 3 also serves as a deflector, the sealing effect of the labyrinth is increased by the recess 7. In the case of the maximum radial displacement of the bearing relative to the stopper 4, the support ring 1 avoids contact of the rotating inner ring 5 of the bearing with the outer surface of the hub of the stop holder 4.
