ENSEMBLE DE DIRECTIONSTEERING ASSEMBLY
La présente invention concerne un ensemble de direction, par exemple pour un véhicule tel qu'un véhicule automobile, un 5 simulateur de conduite, ou autre. The present invention relates to a steering assembly, for example for a vehicle such as a motor vehicle, a driving simulator, or the like.
De manière conventionnelle, un ensemble de direction de véhicule, notamment d'une voiture automobile, comporte une colonne de direction à l'extrémité de laquelle est fixé un volant, lequel comprend une partie centrale appelée moyeu et un anneau que le conducteur peut tourner pour diriger le véhicule. La colonne de direction est reliée au pivot des roues par un mécanisme d'engrenages et de barres de timonerie. La rotation de l'anneau permet de tourner les roues directrices et ainsi de diriger le véhicule. Conventionally, a vehicle steering assembly, in particular a motor vehicle, comprises a steering column at the end of which is fixed a steering wheel, which comprises a central part called hub and a ring that the driver can turn to direct the vehicle. The steering column is connected to the wheel pivot by a gear mechanism and wheelbars. Rotation of the ring rotates the steering wheels and thus directs the vehicle.
Pour des raisons d'ergonomie et de sécurité, les constructeurs automobiles ont tendance à regrouper certaines commandes sur le moyeu, par exemples la commande de l'autoradio, du régulateur de vitesse et de la boite de vitesse. Le conducteur peut ainsi commander certains équipements de son véhicule sans avoir à quitter la route des yeux. Cependant, du fait de la rotation du moyeu central solidairement avec l'anneau, la commande de ces appareils devient difficile, voir impossible, lorsque l'angle de rotation du volant dépasse un certain angle par rapport à la position de repos (qui correspond à la trajectoire rectiligne du véhicule). De plus, un coussin gonflable de sécurité (communément désigné par la marque AirBag) est généralement placé à l'intérieur du moyeu. Le déploiement de ce coussin pouvant survenir alors que le volant est tourné par rapport à sa position de repos, on donne au coussin déployé une forme ronde ou cylindrique, alors que pour des raisons d'efficacité de retenue du 2876073 2 conducteur, il serait préférable de lui donner une forme allongée, d'ellipsoïde par exemple. For reasons of ergonomics and safety, car manufacturers tend to group some controls on the hub, for example the control of the car radio, cruise control and gearbox. The driver can thus control certain equipment of his vehicle without having to leave the road of the eyes. However, because of the rotation of the central hub integrally with the ring, the control of these devices becomes difficult, if not impossible, when the angle of rotation of the steering wheel exceeds a certain angle with respect to the rest position (which corresponds to the rectilinear trajectory of the vehicle). In addition, an airbag (commonly referred to as AirBag) is generally placed inside the hub. The deployment of this cushion may occur while the steering wheel is rotated relative to its rest position, it gives the deployed cushion a round or cylindrical shape, while for reasons of efficiency of restraint of the 2876073 2 driver, it would be preferable to give it an elongated shape, of ellipsoid for example.
Des solutions ont donc été proposées afin de désolidariser le moyeu central de l'anneau de sorte que la rotation de l'anneau n'entraîne pas celle du moyeu, lequel reste fixe. Ainsi, la demande de brevet français FR 2828471 déposée par la demanderesse décrit un ensemble de direction comportant des moyens permettant de désolidariser le moyeu central de l'anneau d'un volant, le moyeu restant fixe lorsque l'anneau est mis en rotation. Un capteur angulaire mesure la position angulaire de l'anneau, laquelle est communiquée à un système électrique commandant l'orientation des roues directrices. Solutions have therefore been proposed in order to separate the central hub of the ring so that the rotation of the ring does not cause that of the hub, which remains fixed. Thus, the French patent application FR 2828471 filed by the applicant describes a steering assembly comprising means for separating the central hub of the ring of a steering wheel, the hub remaining fixed when the ring is rotated. An angular sensor measures the angular position of the ring, which is communicated to an electrical system controlling the orientation of the steering wheels.
On connaît également de la demande de brevet français FR2833915, déposée par la demanderesse, un ensemble de direction de véhicule comportant des moyens pour mettre le moyeu central en rotation avec la colonne de direction et agencés, lors d'une rotation de l'anneau, pour faire tourner le moyeu dans le même sens que l'anneau jusqu'à un angle prédéterminé de celui-ci, une rotation de l'anneau au-delà de l'angle prédéterminé ne provoquant pas de rotation additionnelle du moyeu. French patent application FR2833915, filed by the applicant, also discloses a vehicle steering assembly comprising means for rotating the central hub with the steering column and arranged during a rotation of the ring, for rotating the hub in the same direction as the ring to a predetermined angle thereof, rotation of the ring beyond the predetermined angle does not cause additional rotation of the hub.
On connaît également, du brevet US4932285 au nom de la société Izumi, un système permettant de maintenir immobile par rapport au conducteur le moyeu central d'un volant de véhicule. Ce système est composé d'un mécanisme à engrenages et à courroie maintenue tendue par des rouleaux. Un premier pignon est monté en rotation sur la colonne de direction et un deuxième pignon est monté solidaire du moyeu central. Also known from the patent US4932285 in the name of the company Izumi, a system for maintaining stationary relative to the driver the central hub of a vehicle steering wheel. This system consists of a gear mechanism and belt held tight by rollers. A first gear is rotatably mounted on the steering column and a second gear is mounted integral with the central hub.
2876073 3 Ces solutions existantes sont relativement complexes et nécessitent des changements importants des ensembles de direction actuels. Elles sont donc chères à mettre en oeuvre. De plus, du fait du nombre croissant de commandes disposées sur le moyeu central, le poids de ce moyeu et donc l'inertie du volant ont tendance à augmenter. Le volant étant incliné, généralement supporté par la colonne de direction ellemême inclinée, l'effet pendulaire du volant ne peut plus être négligé. 2876073 3 These existing solutions are relatively complex and require significant changes in current direction sets. They are therefore expensive to implement. In addition, because of the increasing number of controls arranged on the central hub, the weight of this hub and therefore the inertia of the steering wheel tend to increase. The steering wheel being inclined, generally supported by the steering column itself inclined, the pendulum effect of the steering wheel can not be neglected.
La présente invention propose un ensemble de direction comportant un moyeu central fixe, particulièrement économique et simple, ne modifiant que légèrement le volant et permettant de s'affranchir en grande partie de l'effet pendulaire du volant. Le moyeu central peut alors comporter un grand nombre de commandes d'équipements. The present invention provides a steering assembly comprising a fixed central hub, particularly economical and simple, modifying only slightly the steering wheel and to overcome largely the pendulum effect of the steering wheel. The central hub can then include a large number of equipment commands.
De façon plus précise, la présente invention concerne un ensemble de direction, par exemple pour un véhicule, comprenant une colonne de direction montée librement en rotation, un volant comportant un anneau fixé par l'intermédiaire d'au moins un bras à une extrémité de ladite colonne et un moyeu central fixe, caractérisé en ce qu'il comporte une pièce de contournement dudit anneau montée solidairement, d'une part, à une partie fixe et, d'autre part, audit moyeu central. More specifically, the present invention relates to a steering assembly, for example for a vehicle, comprising a steering column mounted freely in rotation, a steering wheel having a ring fixed via at least one arm at one end of said column and a fixed central hub, characterized in that it comprises a bypass member of said ring integrally mounted, on the one hand, to a fixed part and on the other hand, to said central hub.
La colonne de direction est montée libre en rotation dans un support de direction, ledit support constituant avantageusement ladite partie fixe sur laquelle est fixée la pièce de contournement. The steering column is rotatably mounted in a steering support, said support advantageously constituting said fixed part on which is fixed the bypass.
La colonne de direction est montée dans ledit support de direction de préférence par l'intermédiaire d'au moins un palier. The steering column is mounted in said steering support preferably via at least one bearing.
2876073 4 Ledit moyeu central comporte avantageusement au moins un coussin gonflable de sécurité et/ou des moyens pour la commande d'au moins un appareil et/ou au moins un écran d'affichage. The central hub advantageously comprises at least one airbag and / or means for controlling at least one device and / or at least one display screen.
D'autres caractéristiques et avantages de la présente invention vont maintenant être décrits de manière plus détaillée à l'aide des dessins annexés donnés à titre illustratif et non limitatif et dans lesquels: - la figure 1 représente schématiquement un ensemble de direction d'un véhicule automobile conforme à l'invention; - les figures 2 et 3 illustrent un mode de réalisation de l'invention respectivement en perspective et en vue de face. Other features and advantages of the present invention will now be described in more detail with the aid of the accompanying drawings given for illustrative and non-limiting and in which: - Figure 1 shows schematically a steering assembly of a vehicle automobile according to the invention; - Figures 2 and 3 illustrate an embodiment of the invention respectively in perspective and in front view.
Dans les solutions de l'art antérieur, l'immobilisation du moyeu central est généralement réalisée par le passage d'une partie fixe, sur laquelle vient se fixer le moyeu, au travers d'une partie en rotation. Selon la présente invention, la partie fixe est amenée au niveau du moyeu central par une pièce fixée à un support immobile (par rapport à la structure du véhicule) et contournant l'anneau du volant. In the solutions of the prior art, the immobilization of the central hub is generally achieved by the passage of a fixed part, on which is fixed the hub, through a rotating part. According to the present invention, the fixed part is brought to the level of the central hub by a part fixed to a stationary support (relative to the structure of the vehicle) and bypassing the ring of the steering wheel.
Sur la figure 1, qui illustre ce principe de réalisation, un ensemble de direction pour voiture automobile comprend un volant 10 formé d'un anneau 12 fixé à deux bras 14 et 16 et d'un moyeu central 18. Les deux bras 14 et 16 se rejoignent à une extrémité 20 d'une colonne de direction 22. Cette colonne 22 est montée libre en rotation à l'aide de deux paliers 24 et 26 qui sont solidaires de la structure du véhicule. Le moyeu central 18 comprend des commandes d'appareils équipant le véhicule, ainsi qu'un coussin gonflable de sécurité désigné habituellement par la marque AirBag. In Figure 1, which illustrates this embodiment, a steering assembly for a car comprises a steering wheel 10 formed of a ring 12 attached to two arms 14 and 16 and a central hub 18. The two arms 14 and 16 are joined at one end 20 of a steering column 22. This column 22 is rotatably mounted by means of two bearings 24 and 26 which are integral with the vehicle structure. The central hub 18 includes control devices of equipment on the vehicle, and an airbag usually designated by the AirBag brand.
Selon l'invention, le moyeu central 18 est rendu immobile par rapport à la structure du véhicule en le montant solidaire d'une pièce 28 de contournement du volant 10, laquelle est fixée à une partie immobile du véhicule par rapport à la structure du véhicule. Cette pièce immobile est représentée sur les figures 1 et 2 par un cylindre creux 30 entourant les paliers 24 et 26. Le cylindre creux 30 peut, mais non nécessairement, servir de support de fixation de la colonne de direction. De façon à bien faire ressortir la pièce de contournement 28, elle est représentée en traits pointillés sur la figure 1. Cette pièce de contournement peut être réalisée par exemple en plastique par injection. Le moyeu central 18, la pièce de contournement 28 et le cylindre 30 sont donc immobiles par rapport à la structure du véhicule. Notamment, le moyeu 18 ne tourne pas avec l'anneau 12 du volant. According to the invention, the central hub 18 is made immobile with respect to the structure of the vehicle by the integral amount of a part 28 bypassing the steering wheel 10, which is fixed to a stationary part of the vehicle relative to the vehicle structure . This stationary piece is shown in Figures 1 and 2 by a hollow cylinder 30 surrounding the bearings 24 and 26. The hollow cylinder 30 may, but not necessarily, serve as a mounting bracket of the steering column. In order to bring out the bypass piece 28, it is shown in dashed lines in FIG. 1. This bypass can be made for example of plastic by injection. The central hub 18, the bypass piece 28 and the cylinder 30 are therefore immobile with respect to the structure of the vehicle. In particular, the hub 18 does not rotate with the ring 12 of the steering wheel.
Sur les figures 2 et 3, le moyeu central 18 est fixé au cylindre immobile 30 par l'intermédiaire de la pièce de contournement 28. L'anneau 12 du volant est fixé à l'extrémité 20 de la colonne de direction 22 à l'aide des deux bras 14 et 16. Lorsque l'anneau 12 tourne, le moyeu central 18 reste immobile. Le moyeu comporte un coussin gonflable (non représenté) dans sa partie centrale, des commandes 32 d'équipements du véhicule et un écran 34, du type LCD par exemple, permettant d'afficher des informations relatives au véhicule (fermeture des portes, gonflage des pneumatiques, etc.) et/ou à la conduite du véhicule (vitesse instantanée, alertes diverses, etc.). Les flèches 36 et 38 indiquent les sens de rotation de l'anneau 12. In FIGS. 2 and 3, the central hub 18 is fixed to the stationary cylinder 30 via the bypass piece 28. The ring 12 of the steering wheel is fixed at the end 20 of the steering column 22 to the using the two arms 14 and 16. When the ring 12 rotates, the central hub 18 remains stationary. The hub comprises an airbag (not shown) in its central part, vehicle equipment controls 32 and a screen 34, of the LCD type, for example, for displaying information relating to the vehicle (closing the doors, inflating the vehicles). tires, etc.) and / or driving the vehicle (instantaneous speed, various alerts, etc.). The arrows 36 and 38 indicate the directions of rotation of the ring 12.
Le moyeu central ne comporte bien entendu pas nécessairement 30 tous ces éléments. Le moyeu peut être avantageusement réalisé en plastique, mais tout autre matériau approprié pourrait convenir. The central hub does not necessarily include all these elements. The hub can be advantageously made of plastic, but any other suitable material could be suitable.
2876073 6 On remarque que la solution proposée par la présente invention est simple et économique, ne modifiant que légèrement les volants existants. Le moyeu central peut être de grande dimension, sans augmenter l'effet pendulaire du volant, et ainsi recevoir des commandes en relativement grand nombre et même au moins un écran d'affichage. La connexion électrique des diverses commandes, de l'écran et du coussin gonflable équipant le moyeu central ne pose pas de difficultés, pouvant être réalisée par exemple par surmoulage. 20 It will be noted that the solution proposed by the present invention is simple and economical, modifying only slightly existing flywheels. The central hub can be large, without increasing the pendulum effect of the steering wheel, and thus receive orders in relatively large numbers and even at least one display screen. The electrical connection of the various controls, the screen and the airbag equipping the central hub does not pose any difficulties, which can be achieved for example by overmolding. 20
