Abstract

This safety ring 8 guarantees that the screw 5 for clamping the cardan fork joint 1 is correctly placed in the groove 11 of the gear 6 of the steering box, and it also guarantees clamping of this screw to provide good coupling of the lower steering control shaft to the steering box, on the one hand, or to the upper shaft, on the other hand.

Description

L'invention a pour objet une bague destinée à assurer l'accouplement correct de l'arbre inférieur d'une commande de direction au pignon du bottier de direction et à l'arbre supérieur, dans des conditions de médiocre accessibilité et visibilité de ces organes. The subject of the invention is a ring intended to ensure the correct coupling of the lower shaft of a direction control to the pinion of the steering boot and to the upper shaft, under conditions of poor accessibility and visibility of these members. .

I1 est connu que l'accouplement des organes précités s'effectue normalement par le serrage d'une vis qui relie la fourche du 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 coupling of the abovementioned members is normally carried out by tightening a screw which connects the fork of the universal joint of the lower shaft of the steering control to the pinion of the steering boot or to the shaft. superior.

Cette solution est peu fiable pour la sécurité du véhicule, en ce sens que, dans l'opération d'accouplement de l'arbre inférieur de la commande de direction au pignon du bottier de direction, d'un côté, et à l'arbre supérieur, de l'autre, l'ouvrier chargé du montage ne dispose que d'une médiocre visibilité pour vérifier de façon certaine que la vis est exactement engagée dans la gorge du pignon ou de l'arbre supérieur. This solution is unreliable for vehicle safety, in the sense that, in the operation of coupling the lower shaft of the steering control to the pinion of the steering boot, on one side, and to the shaft on the other, the worker in charge of assembly has only poor visibility to verify with certainty that the screw is exactly engaged in the groove of the pinion or of the upper shaft.

On peut déduire de ce qui précède que le défaut d'engagement de la vis de serrage peut entratner le grave inconvénient de séparation des organes d'accouplement, en entratnant un grave préjudice de la sécurité du véhicule, par manque de transmission de la rotation du volant. It can be deduced from the above that the failure to engage the clamping screw can cause the serious drawback of separation of the coupling members, causing serious damage to vehicle safety, by lack of transmission of the rotation of the steering wheel.

L'invention a pour but de réaliser une bague de sécurité destinée à permettre de réaliser un accouplement correct de l'arbre inférieur de commande de direction au pignon du bottier de direction et à l'arbre supérieur, caractérisée en ce que, outre que la bague garantit le bon positionnement de la vis, elle garantit en outre le serrage de la vis utilisée pour réaliser l'accouplement de l'arbre inférieur de commande de la direction au boîtier de direction, d'une part, ou à l'arbre supérieur d'autre part. The object of the invention is to produce a safety ring intended to allow correct coupling of the lower steering control shaft to the pinion of the steering boot and to the upper shaft, characterized in that, in addition to the ring guarantees the correct positioning of the screw, it also guarantees the tightening of the screw used to couple the lower steering control shaft to the steering box, on the one hand, or to the upper shaft on the other hand.

Le but précité est atteint au moyen d'une bague de sécurité caractérisée en ce qu'elle comprend une pat te de forme appropriée et un trou au moyen duquel la bague se monte sur un tourillon cylindrique du pignon du bottier de direction, tourillon sur lequel elle peut tourner librement et est retenue par une bague d'arrêt (bague Seeger) sans gorge. The above-mentioned object is achieved by means of a safety ring, characterized in that it comprises a lug of suitable shape and a hole by means of which the ring is mounted on a cylindrical journal of the pinion of the steering boot, journal on which it can rotate freely and is retained by a stop ring (Seeger ring) without groove.

D'autres buts et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et en regard des dessins annexés sur lesquels,
la figure 1 est une vue éclatée de l'objet de l'invention t
la figure 2 est une vue en perspective de la bague de sécurité destinée à assurer un accouplement correct et qui fait l'objet de l'invention.Other objects and advantages of the invention will be better understood on reading the description which will follow, given solely by way of example, and with reference to the appended drawings in which,
Figure 1 is an exploded view of the object of the invention t
Figure 2 is a perspective view of the safety ring intended to ensure correct coupling and which is the subject 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 est inséré l'arbre inférieur, non représenté sur le dessin, on a indiqué en 4 un trou traversant dans lequel on enfile une vis d'assemblage 5 destinée à serrer une fourche 1 du joint de
Cardan de l'arbre inférieur, non représenté, de commande de la direction, sur le pignon 6 du bottier de direction ou sur l'arbre supérieur, non rçprésenté ; on a indiqué en 7 un écrou qui sert pour le serrage de la vis 5 et en 8 une bague qui se monte sur un tourillon cylindrique 9 du pignon 6 du bottier de direction, tourillon sur lequel la bague peut tourner librement et est retenue par une bague d'arrêt 10. On a indiqué en 11 une gorge qui donne passage à la vis 5.In Figure 1, there is indicated at 1 a fork on which are made, in the upper part, holes 2 and 3 in which is inserted the lower shaft, not shown in the drawing, there is indicated at 4 a through hole in which a threading screw 5 is threaded intended to tighten a fork 1 of the gasket
Gimbal of the lower shaft, not shown, for steering control, on the pinion 6 of the steering box or on the upper shaft, not shown; a nut has been indicated at 7 which is used for tightening the screw 5 and at 8 a ring which is mounted on a cylindrical journal 9 of the pinion 6 of the steering boot, a journal on which the ring can rotate freely and is retained by a stop ring 10. A groove has been indicated at 11 which gives passage to the screw 5.

Sur la figure 2, on a indiqué en 8 une bague dans laquelle est pratiqué un trou 12 au moyen duquel cette bague est emboîtée sur le tourillon 9 du pignon 6 (figure 1) et, en 13, on a indiqué une patte présentant une forme appropriée et qui se place entre les pattes de la fourche 1, pour déterminer la fixation exacte de la vis 5, en garantissant ainsi que cette vis sera engagée dans la gorge 11 du pignon 6 ou de l'arbre non représenté ; en 10, on a indiqué une bague d'arrêt (bague
Seeger) sans gorge qui retient la bague 8 sur le tourillon cylindrique 9 du pignon 6 (figure 1).In Figure 2, there is indicated at 8 a ring in which is made a hole 12 by means of which this ring is fitted on the pin 9 of the pinion 6 (Figure 1) and, at 13, there is indicated a tab having a shape appropriate and which is placed between the legs of the fork 1, to determine the exact fixing of the screw 5, thus guaranteeing that this screw will be engaged in the groove 11 of the pinion 6 or of the shaft not shown; at 10, we indicated a stop ring (ring
Seeger) without groove which retains the ring 8 on the cylindrical pin 9 of the pinion 6 (Figure 1).

Pour monter correctement le dispositif selon l'invention, le monteur doit procéder comme suit : il engage le pignon 6 du bottier de direction, sur lequel la bague 8 a été préalablement montée, dans la fourche cannelée 1. To correctly mount the device according to the invention, the fitter must proceed as follows: he engages the pinion 6 of the steering boot, on which the ring 8 has been previously mounted, in the grooved fork 1.

Ensuite, il enfile la vis 5 dans le trou traversant 4 et, avant de la serrer au moyen de l'écrou 7, il doit s'assurer que le passage au droit du trou 4 de la fourche 1 n'est pas obstrué par la patte de la bague 8. Then, he threads the screw 5 in the through hole 4 and, before tightening it by means of the nut 7, he must make sure that the passage to the right of the hole 4 of the fork 1 is not obstructed by the ring tab 8.

Si le monteur monte la vis 5 alors que la fourche 1 n'est pas engagée dans la gorge 11 du pignon 6 ou de l'arbre, non représenté, il n'y a pas transmission de la rotation du volant, de sorte que l'anomalie est immédiatement détectée. If the assembler mounts the screw 5 while the fork 1 is not engaged in the groove 11 of the pinion 6 or of the shaft, not shown, there is no transmission of the rotation of the flywheel, so that the the anomaly is immediately detected.

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.
