Description

SYSTÈME DE FIXATION DES COMMANDES SECONDAIRES SITUÉES SOUS LE VOLANT D'UN VÉHICULE AUTOMOBILE La présente invention concerne un système de fixation des commandes secondaires situées sous le volant d'un véhicule automobile émergeant d'un habillage de la colonne de direction, les commandes ayant la forme de manettes insérées dans des ouvertures correspondantes. The present invention relates to a system for attaching secondary controls located under the steering wheel of a motor vehicle emerging from a casing of the steering column, the controls having the same function as the steering wheel. form of levers inserted into corresponding openings.

Un tel agencement des commandes secondaires est connu, par exemple, du brevet américain US 5,769,649 Al. Les deux commandes secondaires montrées dans ce document sont réalisées par des manettes émergeant de part et d'autre de l'habillage de la colonne de direction derrière le volant. Elles sont fixées à l'habillage par une interface de type glissière avec un clipsage de fin de course. Ce mode de fixation présente l'inconvénient de créer toujours un jeu qui se traduit par des vibrations de la manette pendant la conduite. Ceci est inacceptable pour l'utilisateur d'un véhicule et demande une fixation supplémentaire des manettes au moyen de cales pour compenser ce jeu. En outre, la mise au point d'une telle fixation reste délicate. Such an arrangement of secondary controls is known, for example, from US Pat. No. 5,769,649 A1. The two secondary controls shown in this document are made by joysticks emerging on either side of the upholstery of the steering column behind the wheel. They are fixed to the cladding by a slide-type interface with an end-of-stroke clipping. This method of attachment has the disadvantage of always creating a game that results in vibrations of the joystick while driving. This is unacceptable for the user of a vehicle and requires additional fixing of the levers by means of wedges to compensate for this game. In addition, the development of such a binding remains delicate.

C'est le but de la présente invention de remédier à ces inconvénients et de proposer un système de fixation des commandes secondaires qui soit simple à réaliser, fiable en évitant des jeux qui apparaissent lors du montage et qui puisse être mis au point par une simple action de vissage. It is the object of the present invention to overcome these drawbacks and to propose a system for attaching secondary controls that is simple to perform, reliable, avoiding games that appear during assembly and that can be developed by a simple screwing action.

L'objet de la présente invention est un système de fixation des commandes secondaires situées sous le volant d'un véhicule automobile émergeant d'un habillage de la colonne de direction, les commandes secondaires présentant la forme de manettes insérées dans des The object of the present invention is a system for fixing the secondary controls located under the steering wheel of a motor vehicle emerging from a dressing of the steering column, the secondary controls in the form of joysticks inserted into

ouvertures correspondantes, dans lequel les manettes sont entraînées et insérées dans les ouvertures correspondantes par des vérins à vis, qui sont entraînés à leur tour par un système d'engrenage conique. corresponding openings, wherein the levers are driven and inserted into the corresponding openings by screw jacks, which are in turn driven by a bevel gear system.

Avantageusement, les vérins à vis comprennent un axe fileté et un écrou vissé sur l'axe fileté fermant l'extrémité d'un trou central de la manette. Advantageously, the screw jacks comprise a threaded shaft and a nut screwed onto the threaded shaft closing the end of a central hole of the handle.

Avantageusement, le système d'engrenage conique comprend une 10 roue dentée et des pignons dentés fixés à l'extrémité libre des axes filetés par des goupilles coniques. Advantageously, the bevel gear system comprises a gearwheel and toothed gears attached to the free end of the threaded pins by tapered pins.

Dans un mode de réalisation préféré, le pignon et la roue dentée forment des engrenages coniques à axes concourants perpendiculaires à 15 denture droite. In a preferred embodiment, the pinion and the gearwheel form bevel gears with concurrent axes perpendicular to the right toothing.

Avantageusement, la roue dentée est entraînée en rotation par un axe de commande comportant une empreinte de vis à six pans creux disposée sur l'axe central de rotation. Avantageusement, les prolongations géométriques des cônes primitifs de la roue dentée et des pignons à axes concourants perpendiculaires croisent l'axe de rotation des axes filetés. Advantageously, the toothed wheel is rotated by a control shaft comprising an Allen screw recess disposed on the central axis of rotation. Advantageously, the geometric extensions of the primitive cones of the toothed wheel and sprockets with perpendicular axes intersect the axis of rotation of the threaded axles.

25 Selon un mode de réalisation préféré, les vérins à vis comportent un pignon qui va tourner en raison de son positionnement sur la roue dentée dans le sens inverse de celui de l'autre pignon, le sens du pas de filetage des axes étant inversé. According to a preferred embodiment, the screw jacks comprise a pinion which will rotate due to its positioning on the toothed wheel in the opposite direction to that of the other pinion, the direction of the thread pitch of the axes being reversed.

30 De préférence, le mouvement de la manette dans son ouverture correspondante est limité par un clip de fin de course. 20 Preferably, the movement of the joystick in its corresponding aperture is limited by an end-of-stroke clip. 20

Avantageusement, l'extrémité de l'axe de commande comporte une empreinte de vis à six pans creux pour recevoir la partie mâle d'une visseuse. Advantageously, the end of the control shaft has an Allen screw recess for receiving the male part of a screwdriver.

L'invention sera mieux comprise à l'aide de la description qui suit, en référence aux dessins schématiques annexés représentant un exemple d'un système de fixation selon l'invention. D'autres avantages et caractéristiques sont mis en évidence à la lecture de la description. The invention will be better understood from the description which follows, with reference to the accompanying schematic drawings showing an example of a fastening system according to the invention. Other advantages and features are highlighted by reading the description.

Fig. 1 montre deux commandes secondaires montées sur l'habillage d'une colonne de direction d'un véhicule; Fig. 1 shows two secondary controls mounted on the upholstery of a steering column of a vehicle;

Fig.2 montre schématiquement le principe de la fixation des commandes secondaires selon l'invention; et Figs 3A et 3B montrent schématiquement vu de dessus et en coupe transversale un mode de réalisation du système de fixation selon l'invention. Fig.2 schematically shows the principle of fixing the secondary controls according to the invention; and FIGS. 3A and 3B show schematically seen from above and in cross section an embodiment of the fastening system according to the invention.

20 Fig. 1 est une vue de dessus de l'habillage 2 de la colonne de direction 3 (enlevée) avec deux commandes secondaires 1 disposées de chaque côté de la colonne de direction 3 sur l'habillage 2. Les commandes secondaires 1 ont la forme de manettes 4 et elles peuvent effectuer plusieurs fonctions chacune, comme la commande de 25 l'essuyage des vitres, la commande des clignotants, des commandes du système audio, etc. Fig. 1 is a top view of the cladding 2 of the steering column 3 (removed) with two secondary controls 1 disposed on each side of the steering column 3 on the cladding 2. The secondary controls 1 are in the form of joysticks 4 and they can perform several functions each, such as wiper control, turn signal control, audio system controls, etc.

Le système de fixation selon l'invention se trouve situé à l'intérieur de l'habillage 2 de la colonne de direction entre les deux manettes 4 et 30 seule l'extrémité de l'axe de commande 11 comportant l'empreinte de vis à six pans creux 13 du système est visible de l'extérieur.15 The fastening system according to the invention is located inside the casing 2 of the steering column between the two levers 4 and 30 only the end of the control shaft 11 comprising the screw cavity to hexagon socket 13 of the system is visible from the outside.15

Fig. 2 montre schématiquement une vue de côté du système de fixation selon l'invention. Les manettes 4 sont disposées dans des ouvertures 5 correspondantes dans lhabillage 2 de la colonne de direction 3 avec leurs axes longitudinaux disposés sur un même axe. Fig. 2 schematically shows a side view of the fastening system according to the invention. The levers 4 are arranged in corresponding openings 5 in the lining 2 of the steering column 3 with their longitudinal axes arranged on the same axis.

Les manettes sont reliées par des écrous 16, situés à l'extrémité d'un trou central, à des axes filetés 8. Les axes 8 sont fixés à leur extrémité libre à des pignons coniques dentés 9. La liaison en rotation entre l'axe fileté 8 et le pignon 9 est réalisée par la goupille conique 19 (visible sur Fig. 3A). Les écrous 16 et les axes filetés 8 forment un système de vérin à vis 6. Les axes filetés 8 des vérins à vis sont entraînés en rotation par l'intermédiaire d'un système d'engrenage 7 comportant une roue dentée conique 10 dans laquelle les pignons 9 viennent s'engrener. Les pignons 9 et la roue dentée 10 forment des systèmes d'engrenages coniques à axes concourants perpendiculaires à denture droite. L'axe de rotation 12 (visible sur les figures 3) de la roue dentée 10 est perpendiculaire à l'axe de rotation des axes filetés 8. Les prolongations des cônes primitifs de la roue dentée 10 et des pignons 9 à axes concourants croisent l'axe des axes filetés 8. The levers are connected by nuts 16, located at the end of a central hole, to threaded pins 8. The pins 8 are fixed at their free end to beveled bevel gears 9. The connection in rotation between the axis threaded 8 and the pinion 9 is formed by the taper pin 19 (visible in Fig. 3A). The nuts 16 and the threaded axles 8 form a screw jack system 6. The threaded axles 8 of the screw jacks are rotated by means of a gear system 7 comprising a conical gear 10 in which the gables 9 come to mesh. The pinions 9 and the toothed wheel 10 form conical gears systems with concurrent axes perpendicular to right teeth. The axis of rotation 12 (visible in FIG. 3) of the toothed wheel 10 is perpendicular to the axis of rotation of the threaded axles 8. The prolongations of the pitch cones of the toothed wheel 10 and the pinions 9 with intersecting axes intersect the axis of the threaded pins 8.

La roue dentée 10 est entraînée en rotation par l'intermédiaire d'une visseuse 14 qui peut être accouplée à l'axe de commande 11 qui comporte de préférence une empreinte de vis à six pans creux 13. The toothed wheel 10 is rotated by means of a screwdriver 14 which can be coupled to the control shaft 11, which preferably comprises an Allen screw 13.

En tournant la visseuse 14, accouplée à l'axe de commande 11, la roue dentée 10 est entraînée en rotation, ce qui fait tourner les pignons 9 ainsi que les axes filetés 8 accouplés à ces derniers. Le sens du pas de filetage des axes filetés 8 à droite et à gauche est inversé car le sens de rotation des deux pignons 9 est inversé également. Ainsi, en tournant la roue dentée 10, les deux manettes 4 se déplacent toutes les deux en même temps vers l'intérieur de leurs ouvertures 5 correspondantes. By turning the screwdriver 14, coupled to the control shaft 11, the toothed wheel 10 is rotated, which rotates the pinions 9 and the threaded pins 8 coupled thereto. The direction of the thread pitch of the threaded pins 8 on the right and on the left is reversed because the direction of rotation of the two pinions 9 is reversed as well. Thus, by turning the toothed wheel 10, the two levers 4 move both at the same time towards the inside of their corresponding openings 5.

Avantageusement, comme représenté, les pignons 9 et la roue dentée 10 sont coniques. Quand les deux manettes 4 arrivent au fond de leurs ouvertures correspondantes 5, elles viennent buter contre des anneaux d'arrêt anti-retour 15 qui empêchent le déblocage des manettes 4 dans leur position de fixation finale dans le trou correspondant. Advantageously, as shown, the pinions 9 and the toothed wheel 10 are conical. When the two handles 4 arrive at the bottom of their corresponding openings 5, they abut against non-return stop rings 15 which prevent the release of the levers 4 in their final fixing position in the corresponding hole.

Les figures 3 montrent un mode de réalisation du système de fixation selon l'invention vu de dessus (Fig. 3 A) et en coupe transversale (Fig. 3 B) plus détaillé. Les axes filetés 8 et l'axe de rotation 12 de la roue dentée 10 sont montés dans des paliers 17 et 18 respectivement. Ces paliers font partie de la structure interne de l'habillage 2. Cette structure comporte des anneaux d'arrêt 15 nécessaires pour maintenir l'axe 8 en position dans le palier 17, des anneaux d'arrêt 21 nécessaires pour maintenir l'axe de commande 11 en position dans le palier 18, un axe d'arrêt 20 nécessaire pour maintenir la roue dentée 10 en bûtée sur la collerette de l'axe de commande 11. Figures 3 show an embodiment of the fastening system according to the invention seen from above (Figure 3 A) and in cross section (Figure 3 B) more detailed. The threaded shafts 8 and the axis of rotation 12 of the toothed wheel 10 are mounted in bearings 17 and 18 respectively. These bearings are part of the internal structure of the casing 2. This structure comprises stop rings 15 necessary to maintain the axis 8 in position in the bearing 17, stop rings 21 necessary to maintain the axis of control 11 in position in the bearing 18, a stop pin 20 necessary to keep the toothed wheel 10 flush on the flange of the control shaft 11.

Dans l'exemple montré, les deux axes filetés 8 se trouvent sur le même axe géométrique qui croise l'axe de rotation 12 de la roue dentée 10. I1 est également possible de désaxer ces deux axes filetés 8 à condition qu'ils croisent néanmoins l'axe de rotation 12 de la roue dentée 10. In the example shown, the two threaded pins 8 are on the same geometrical axis which crosses the axis of rotation 12 of the toothed wheel 10. It is also possible to offset these two threaded axes 8 provided that they nevertheless cross the axis of rotation 12 of the toothed wheel 10.

Il est également possible de prévoir plus de deux commandes 25 secondaires, par exemple quatre, deux de chaque côté, angulairement décalées. It is also possible to provide more than two secondary commands, for example four, two on each side, angularly offset.
