Description

La présente invention a pour objet une articulation perfectionnée destinée particulièrement, mais non exclusivement à être montée sur les capots avant ou arrière de véhicules automobiles telle que définie par le préambule de la revendication principale.The present invention relates to an improved articulation intended particularly, but not exclusively, to be mounted on the front or rear hoods of motor vehicles as defined by the preamble of the main claim.

Le publication FR-A-592 872 décrit une charnière qui comporte deux têtes comprenant chacune un embouti sphérique. Placée entre les deux têtes, on trouve une pièce d'appui sphérique, constituée d'un métal antifriction. Les deux têtes et la pièce d'appui sont traversées par un axe. Il y a donc une possibilité de centrage automatique entre les deux têtes et de réglage automatique de cette charnière par rapport à une autre charnière du même ouvrant.The publication FR-A-592 872 describes a hinge which comprises two heads each comprising a spherical stamping. Placed between the two heads, there is a spherical support piece, made of an anti-friction metal. The two heads and the support piece are crossed by an axis. There is therefore a possibility of automatic centering between the two heads and of automatic adjustment of this hinge relative to another hinge of the same opening.

La publication GB-A-2 101 203 concerne une articulation dont les parties mobile et fixe de forme tronconique sont assemblées, avec interposition d'une rondelle anti-friction, par un rivet de forme conjuguée. Cette forme tronconique facilite le positionnement des différents éléments formant l'articulation.The publication GB-A-2 101 203 relates to a joint whose movable and fixed parts of frustoconical shape are assembled, with the interposition of an anti-friction washer, by a rivet of conjugate shape. This frustoconical shape facilitates the positioning of the various elements forming the joint.

Ces dispositifs ont l'inconvénient de ne permettre aucun déplacement relatif des parties fixes et mobiles exception faite du mouvement de rotation pour lequel ils sont conçus. Or lors de la fabrication d'un véhicule, il se produit des distorsions angulaires et de position sur les portées et ouvertures destinées à recevoir les articulations. De ce fait, le montage des ouvrants nécessite la mise sous contrainte des articulations pour pouvoir les fixer. Cette mise sous contrainte rend le montage malaisé et provoque en outre une dureté de fonctionnement, du bruit et une usure beaucoup plus rapide des articulations.These devices have the drawback of not allowing any relative movement of the fixed and mobile parts except for the rotational movement for which they are designed. However, during the manufacture of a vehicle, angular and positional distortions occur on the surfaces and openings intended to receive the joints. Therefore, the assembly of the openings requires the stressing of the joints to be able to fix them. This stressing makes assembly difficult and also causes hardness of operation, noise and much faster wear of the joints.

La présente invention remédie à ces inconvénients en permettant en plus du mouvement de rotation propre à sa fonction un déplacement angulaire relatif des parties fixes et mobiles, assurant un montage aisé et un fontionnement sans contrainte et sans jeu.The present invention overcomes these drawbacks by allowing, in addition to the rotation movement specific to its function, a relative angular displacement of the fixed and mobile parts, ensuring easy mounting and operation without constraint and without play.

L'articulation perfectionnée selon l'invention est composée d'un support fixe portant un palier sphérique destiné à recevoir l'extrémité sphérique d'un col de cygne mobile, l'ensemble étant articulé autour d'un axe ayant une portée également sphérique après interposition de deux rondelles de glissement.The improved articulation according to the invention is composed of a fixed support carrying a spherical bearing intended to receive the spherical end of a mobile gooseneck, the assembly being articulated around an axis having a bearing also spherical after interposition of two sliding washers.

L'invention sera mieux comprise à la lecture de la description qui suit d'une de ses réalisations préférées à l'examen des dessins annexés sur lesquels:

  • La figure 1 est une vue en élévation de l'articulation perfectionnée selon l'invention;
  • La figure 2 est une vue de l'articulation selon la flèche F de la figure 1 avec coupe partielle à plus grande échelle montrant l'axe d'articulation;
  • La figure 3 est une vue en plan de ladite articulation de la figure 1.
The invention will be better understood on reading the following description of one of its preferred embodiments on examining the appended drawings in which:
  • Figure 1 is an elevational view of the improved joint according to the invention;
  • Figure 2 is a view of the joint according to arrow F of Figure 1 with partial section on a larger scale showing the axis of articulation;
  • FIG. 3 is a plan view of said articulation of FIG. 1.

En se reportant aux figures 1, 2 et 3, on voit que l'articulation selon l'invention est composée d'une part, d'un support fixe 1 de forme triangulaire, dont la base est pliée perpendiculairement pour former une patte de fixation 2 comportant des alésages 3 permettant de rendre ledit support solidaire de la carrosserie par boulonnage, et d'autre part, d'une partie mobile en col ce cygne 4 destinée à être fixée au capot du véhicule, l'ensemble étant réuni par un axe d'articulation 5 avec interposition de deux rondelles 6 et 7 de glissement.Referring to Figures 1, 2 and 3, we see that the joint according to the invention is composed on the one hand, of a fixed support 1 of triangular shape, the base of which is folded perpendicularly to form a fixing lug 2 comprising bores 3 making it possible to make said support integral with the bodywork by bolting, and on the other hand, a movable part in neck this swan 4 intended to be fixed to the hood of the vehicle, the whole being joined by an axis articulation 5 with interposition of two sliding washers 6 and 7.

L'extrémité supérieure du support fixe 1 comporte un embouti formant palier sphérique 1A pourvu en son centre d'un orifice 1B pour le passage de l'axe d'articulation 5.The upper end of the fixed support 1 has a stamped forming a spherical bearing 1A provided in its center with an orifice 1B for the passage of the articulation axis 5.

De même l'extrémité de la partie mobile 4 comporte également un embouti sphérique 4A avec un alésage 4B destiné à recevoir l'axe d'articulation 5. Celui-ci comporte à l'une de ses extrémités une portée sphérique 5A et dans sa partie médiane un moletage 5B destiné à assurer son blocage dans l'alésage 4B de la partie mobile 4 en col de cygne. Des rondelles de glissement 6 et 7 sont disposées de part et d'autre du palier sphérique 1A de la partie fixe 1.Similarly, the end of the movable part 4 also includes a spherical stamped 4A with a bore 4B intended to receive the hinge pin 5. The latter has at one of its ends a spherical bearing 5A and in its part middle knurling 5B intended to ensure its blocking in the bore 4B of the movable part 4 in swan neck. Sliding washers 6 and 7 are arranged on either side of the spherical bearing 1A of the fixed part 1.

Ces rondelles de glissement 6 et 7 sont réalisées en un matériau composite ayant une grande résistance au fluage et un coefficient de frottement très bas.These sliding washers 6 and 7 are made of a composite material having a high creep resistance and a very low coefficient of friction.

Comme on peut le voir sur les figures lors du montage une des rondelles 7 se trouve pincée entre la portée sphérique 5A de l'axe 5 et la portée du support fixe 1, l'autre rondelle 6 se trouvant pincée entre l'autre portée sphérique du support fixe 1 et la portée 4A de la pièce mobile 4 en col de cygne, l'axe 5 étant maintenu en rotation par ses cannelures 5B emmanchées serrées dans l'alésage 4B de la pièce mobile 4 en col de cygneAs can be seen in the figures during assembly, one of the washers 7 is pinched between the spherical bearing 5A of the axis 5 and the bearing of the fixed support 1, the other washer 6 being pinched between the other spherical bearing of the fixed support 1 and the bearing 4A of the moving part 4 in swan neck, the axis 5 being kept in rotation by its grooves 5B fitted tightly in the bore 4B of the moving part 4 in swan neck

L'axe 5 est maintenu en translation par rivetage de son extrémité 5C. Grâce au jeu entre l'alésage 1B du support fixe 1 et l'axe 5, l'embouti sphérique dudit support fixe peut glisser entre les rondelles 6 et 7 autorisant la rotation mais également, et c'est très important lors du montage de l'ensemble, un débattement angulaire relatif entre le support fixe 1 et l'élément mobile 4. Il faut noter que l'articulation selon l'invention malgré le débattement angulaire qu'elle permet fonctionne sans jeu du fait du pincement de l'élément mobile 4 entre les deux rondelles de glissement 6 et 7, évitant ainsi tout bruit pouvant être causé par les vibrations du véhicule en mouvement. De plus, les qualités de glissement du matériau constituant les rondelles évitent d'avoir à graisser l'articulation.The axis 5 is held in translation by riveting its end 5C. Thanks to the play between the bore 1B of the support fixed 1 and axis 5, the spherical stamping of said fixed support can slide between the washers 6 and 7 allowing rotation but also, and this is very important during assembly of the assembly, a relative angular movement between the support fixed 1 and the movable element 4. It should be noted that the articulation according to the invention despite the angular movement that it allows operates without play due to the pinching of the movable element 4 between the two sliding washers 6 and 7 , thus avoiding any noise that may be caused by the vibrations of the moving vehicle. In addition, the sliding qualities of the material constituting the washers avoid having to grease the joint.
