Description
La présente invention a pour objet un dispositif pour assurer la conformité du positionnement de l'arbre inférieur de la commande de direction par rapport au pignon du bottier de direction ou à l'arbre supérieur, dispositif qui comprend un ressort de sécurité muni d'une languette de repérage qui sert pour assurer la conformité du positionnement et/ou de l'assemblage des organes précités. The present invention relates to a device for ensuring the conformity of the positioning of the lower shaft of the steering control with respect to the pinion of the steering boot or to the upper shaft, device which comprises a safety spring provided with a locating tab which serves to ensure the conformity of the positioning and / or the assembly of the abovementioned members.
Il est connu que l'assemblage des organes décrits plus haut s'effectue normalement par le serrage d'une vis qui relie la fourche de joint de Cardan de l'arbre inférieur de la commande de direction au pignon du bottier de direction ou à l'arbre supérieur. It is known that the assembly of the members described above is normally carried out by tightening a screw which connects the universal joint fork of the lower shaft of the steering control to the pinion of the steering boot or to the 'upper tree.
Cette opération est peu fiable pour la sécurité du véhicule, en ce sens que, dans les opérations de positionnement et/ou d'assemblage décrites plus haut, l'ouvrier préposé au montage ne dispose que d'une médiocre visibilité pour vérifier avec certitude que la vis de serrage est exactement engagée dans la gorge du pignon du bottier de direction ou de l'arbre supérieur. This operation is not very reliable for the safety of the vehicle, in the sense that, in the positioning and / or assembly operations described above, the worker in charge of assembly only has poor visibility to verify with certainty that the clamping screw is exactly engaged in the groove of the pinion of the steering box or of the upper shaft.
I1 est connu par ailleurs que les inconvénients décrits plus haut ont été surmontés par les brevets nO 54 187B/86 Et 67 432A/87 de la meme demanderesse. It is also known that the drawbacks described above have been overcome by patents Nos. 54 187B / 86 and 67 432A / 87 by the same applicant.
Les solutions décrites dans ces documents se rapportent à une bague de sécurité destinée à assurer la conformité de l'assemblage de l'arbre inférieur de la commande de direction au pignon du bottier de direction ou à l'arbre supérieur mais si, dlun côté, ces solutions garantissent le parfait positionnement de la vis, d'un autre côté, pour l'opérateur, elles limitent la liberté de mouvement dans les manoeuvres de positionnement et/ou d'assemblage des organes décrits ci-dessus. The solutions described in these documents relate to a safety ring intended to ensure the conformity of the assembly of the lower shaft of the steering control to the pinion of the steering boot or to the upper shaft but if, on one side, these solutions guarantee perfect positioning of the screw, on the other hand, for the operator, they limit the freedom of movement in the positioning and / or assembly maneuvers of the members described above.
En outre, ces solutions exigent des cycles de travail différenciés et, par conséquent, des coats plus élevés. In addition, these solutions require differentiated work cycles and, therefore, higher costs.
La présente invention a pour but de réaliser un ressort de sécurité destiné à assurer la conformité de l'assemblage de l'arbre inférieur de la commande de direction au pignon du bottier de direction ou à l'arbre supérieur, caractérisé en ce que, outre le fait qu'il qarantit le positionnement conforme de la vis, il garantit aussi le serrage de la vis pour l'assemblage des organes précités. The object of the present invention is to produce a safety spring intended to ensure the conformity of the assembly of the lower shaft of the steering control to the pinion of the steering boot or to the upper shaft, characterized in that, in addition the fact that it guarantees the correct positioning of the screw, it also guarantees the tightening of the screw for the assembly of the abovementioned members.
Le but décrit ci-dessus est atteint au moyen d'un ressort de sécurité, caractérisé en ce qu'il comprend une languette de repérage 14, convenablement formée sur le ressort 8 et deux languettes 9 et 10, également formées sur le ressort 8 et qui, dans la position de repos de la languette de repérage 14, ferment la lumière du trou traversant 5 pratiqué sur la fourche 1 et dans lequel on enfile la vis de serrage 4. The object described above is achieved by means of a safety spring, characterized in that it comprises a locating tab 14, suitably formed on the spring 8 and two tabs 9 and 10, also formed on the spring 8 and which, in the rest position of the locating tab 14, close the light of the through hole 5 made on the fork 1 and in which the tightening screw 4 is threaded.
En outre, sur ledit ressort de sécurité 8, sont formées une série de languettes de retenue 11, 12 et 13 qui fixent ledit ressort de sécurité 8 sur la fourche 1 par repliage. In addition, on said safety spring 8, a series of retaining tongues 11, 12 and 13 are formed which fix said safety spring 8 on the fork 1 by folding.
La fixation dudit ressort de sécurité 8 sur la fourche 1 s'effectue en repliant les languettes 11, 12 et 13 respectivement sur les pattes 6 et 7 et sur le dos de la fourche 1. The fixing of said safety spring 8 on the fork 1 is effected by folding the tabs 11, 12 and 13 respectively on the legs 6 and 7 and on the back of the fork 1.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une vue éclatée du détail de l'objet de l'invention ;
la figure 2 est une vue en perspective du ressort de sécurité destiné 9 assurer la conformité de l'assemblage qui constitue l'objet de l'invention.Other characteristics and advantages of the invention will be better understood on reading the following description of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is an exploded view of the detail of the object of the invention;
FIG. 2 is a perspective view of the safety spring intended to ensure the conformity of the assembly which constitutes the object of the invention.
Sur la figure 1, on a indiqué en 1 une fourche sur laquelle sont pratiqués, dans la partie supérieure, des trous 2 et 3 dans lesquels l'arbre inférieur est monté par un croisillon, non représenté sur le dessin ; on a indiqué en 5 un trou traversant dans lequel est enfilée une vis 4 destinée à serrer la fourche 1 du joint de
Cardan de l'arbre inférieur, non représenté, de la commande de direction sur le pignon 17 du bottier de direction ou sur l'arbre supérieur, non représenté t on a indiqué en 15 un écrou de serrage de la vis 4 ; en 8, un ressort de sécurité qui se monte sur la fourche 1, sur laquelle ce ressort est retenu au moyen des languettes 11, 12 et 13, repliées respectivement sur les pattes 6, 7 et sur le dos de la fourche 1, et on a indiqué en 16 une gorge pratiquée sur le pignon 17 de commande du bot- tier de direction et qui détermine le passage de la vis de serrage 4.In Figure 1, there is indicated in 1 a fork on which are made, in the upper part, holes 2 and 3 in which the lower shaft is mounted by a spider, not shown in the drawing; there is indicated at 5 a through hole in which is threaded a screw 4 intended to tighten the fork 1 of the gasket
Cardan shaft of the lower shaft, not shown, of the steering control on the pinion 17 of the steering box or on the upper shaft, not shown t a screw tightening nut 4 has been indicated; at 8, a safety spring which mounts on the fork 1, on which this spring is retained by means of the tongues 11, 12 and 13, folded respectively on the legs 6, 7 and on the back of the fork 1, and indicated at 16 a groove formed on the pinion 17 for controlling the steering box and which determines the passage of the tightening screw 4.
Sur la figure 2, on a indiqué en 8 un ressort de sécurité qui se monte sur la fourche 1 et est retenu sur cette fourche au moyen des languettes 11, 12 et 13 en 14, on a indiqué une languette de repérage qui, sous la poussée du pignon du boitier de direction 17, donne le repérage exact pour le positionnement des organes de l'assemblage qui ont été décrits ci-dessus ; ce repérage exact est donné par le fait que les languettes 9 et 10 étant solidaires de la languette 14, l'élévation de cette dernière entrain également lesdites languettes 9 et 10, lesquelles démasquent alors le trou 5 de la fourche 1. In Figure 2, there is indicated at 8 a safety spring which mounts on the fork 1 and is retained on this fork by means of the tongues 11, 12 and 13 at 14, there is indicated a locating tongue which, under the thrust of the pinion of the steering box 17, gives the exact location for the positioning of the assembly members which have been described above; this exact location is given by the fact that the tongues 9 and 10 being integral with the tongue 14, the elevation of the latter also causes said tongues 9 and 10, which then unmask the hole 5 of the fork 1.
Pour effectuer le montage conforme du dispositif objet de l'invention, l'opérateur doit procéder de la façon suivante : engager le pignon 17 du bottier de direction dans la fourche 1, sur laquelle le ressort de sécurité 8 est déjà monté. To carry out the correct assembly of the device which is the subject of the invention, the operator must proceed as follows: engage the pinion 17 of the steering box in the fork 1, on which the safety spring 8 is already mounted.
Si le passage de lavis 4 n'est pas obstrué par les languettes 8,, 10 du ressort ceci signifie que la fourche I est bien positionnée sur le pignon 17 et on procède alors à l'engagement de la vis 4 dans le trou 5 de la fourche 1 et dans la gorge 16 du pignon 17. If the passage of the wash 4 is not obstructed by the tongues 8, 10 of the spring, this means that the fork I is correctly positioned on the pinion 17 and the screw 4 is then engaged in the hole 5 of the fork 1 and in the groove 16 of the pinion 17.
Si, au moment où l'opérateur monte la vis 4, la fourche 1 n'est pas emmanchée sur le pignon 17, l'anomalie sera évidente dans ce cas puisqu'il n'y aura pas d'entratnement de la fourche 1 en rotation par le volant. If, when the operator mounts the screw 4, the fork 1 is not fitted onto the pinion 17, the anomaly will be obvious in this case since there will be no drive of the fork 1 in rotation by the steering wheel.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of non-limiting example without departing from the scope of the invention.
