Description

BIELLETTE LESTEE DE COMMANDE DE BOITE DE VITESSES  CONNECTED GEAR LINK WITH GEARBOX CONTROL
L'invention a trait au domaine des véhicules automobiles. Plus particulièrement l'invention a trait à la commande de la boîte de vitesses d'un véhicule. The invention relates to the field of motor vehicles. More particularly, the invention relates to the control of the gearbox of a vehicle.
A l'occasion d'un passage de vitesse sur une boîte de vitesses de véhicule automobile, le conducteur agit par l'intermédiaire du levier de changement de vitesse sur des mécanismes dont le mouvement génère, par réaction, une sensation de résistance ou d'accrochage. Cette réaction est due plus particulièrement au déplacement de pièces mécaniques lors de la synchronisation de la vitesse, par exemple l'accouplement d'un crabot sur un pignon. Le document de brevet FR 2 976 994 A1 divulgue un dispositif d'actionnement d'une commande de boîte de vitesses qui comporte un levier de commande ainsi qu'une masse d'inertie reliée cinématiquement au levier via une biellette. L'enseignement est intéressant en ce que la masse apporte un surcroît d'inertie de la commande de vitesse ce qui facilite le passage de vitesse et améliore le ressenti. En revanche cette solution n'est pas économique. On the occasion of a gearshift on a motor vehicle gearbox, the driver acts via the gearshift lever on mechanisms whose movement generates, by reaction, a feeling of resistance or of hanging. This reaction is due more particularly to the displacement of mechanical parts during the synchronization of the speed, for example the coupling of a clutch on a pinion. Patent document FR 2 976 994 A1 discloses a device for actuating a gearbox control which comprises a control lever and a mass of inertia connected kinematically to the lever via a link. The teaching is interesting in that the mass provides an additional inertia of the speed control which facilitates the passage of speed and improves the feeling. On the other hand, this solution is not economical.

La figure 1 est une vue schématique d'un véhicule 2 comprenant un dispositif de commande mécanique 4 de boîte de vitesses conforme à l'invention. Le véhicule 2 comprend plus précisément une boîte de vitesses 6 avec au moins un levier de commande 8, un manche 10 de changement de vitesse pour le conducteur, le dispositif de commande 4 reliant le manche 10 au levier de commande 8 de la boîte de vitesses 6 par une biellette 12 conforme à l'invention. Dans un mode particulier de l'invention la boite de vitesses 6 comprend deux leviers de commande (un seul est représenté), chacun des leviers 8 étant apte à se déplacer par pivotement autour de son axe ou déplacement axial, ces déplacements correspondant au déplacement avant - arrière, ou longitudinal, et/ou droite - gauche, ou transversal, du manche de vitesse 10. On peut voir sur l'image des flèches représentant ces mouvements dont la combinaison permet la sélection des vitesses. Une indication 14 des vitesses pouvant être sélectionnées sur le véhicule est également représentée, les 6 vitesses représentées ne limitant en rien l'invention. Le véhicule 2 peut comprendre un système de câbles 16 reliant le manche de commande 10 au dispositif de commande 4 de façon à transmettre les mouvements du manche de vitesse 10 vers le dispositif de commande 4. Figure 1 is a schematic view of a vehicle 2 comprising a mechanical control device 4 gearbox according to the invention. The vehicle 2 more specifically comprises a gearbox 6 with at least one control lever 8, a handle 10 for shifting the driver, the control device 4 connecting the handle 10 to the control lever 8 of the gearbox 6 by a rod 12 according to the invention. In a particular embodiment of the invention the gearbox 6 comprises two control levers (only one is shown), each of the levers 8 being able to move by pivoting about its axis or axial displacement, these displacements corresponding to the displacement before - Rear, or longitudinal, and / or right - left, or transverse, the speed stick 10. It can be seen in the image arrows representing these movements whose combination allows the selection of speeds. An indication 14 of the selectable speeds on the vehicle is also shown, the 6 speeds shown not limiting the invention. The vehicle 2 may comprise a cable system 16 connecting the control stick 10 to the control device 4 so as to transmit the movements of the speed stick 10 to the control device 4.
La figure 2 est une vue en perspective du dispositif 4 de commande mécanique de boîte de vitesses conforme à l'invention, dans un mode préféré de réalisation. Le dispositif 4 comprend la biellette 12 coopérant avec le levier 8 ou un des leviers de la boite de vitesses (non représentée). La biellette 12 a deux extrémités et comprend un corps métallique 24 (partie encadrée en pointillé sur l'image) et un surmoulage 26 en matière plastique, le corps métallique 24 de la biellette 12 étant destiné à augmenter la masse de la biellette 12 pour apporter un surcroît d'inertie au passage de vitesse. On peut voir sur le haut de l'image un câble 16 du système de câbles vu en relation avec la figure précédente. Le câble 16 relie le dispositif 4 au manche de commande (non représenté). Le passage de vitesse est effectué par le mouvement de la biellette 12, celle-ci pouvant se déplacer sur une distance comprise entre 10mm et 30mm. Le mouvement de la biellette 12 peut être généré par un système de renvoi d'angle 18 de façon à décupler la force nécessaire au passage de vitesse. Le passage de vitesse se fait en l'occurrence par la rotation de l'axe du levier de changement de vitesse 8, celui-ci étant apte à pivoter grâce au mouvement de la biellette 12. Un système de flèches sur l'image permet de visualiser la direction du mouvement de la biellette 12 et le pivotement engendré sur l'axe du levier de vitesse 8, le mode de réalisation présenté ne limitant en rien d'autres modes possibles de déplacement du levier. Dans ce mode préféré de réalisation, la liaison mécanique 20 entre le levier de changement de vitesse 8 et la biellette 12 est une liaison à rotule. La liaison mécanique 22 à l'autre extrémité 30 de la biellette peut être une liaison pivot ou également une liaison à rotule. Une autre biellette (non représenté) du même type que la biellette 12 peut également coopérer avec un autre levier (non représenté) de commande de la boîte de vitesses, cette mesure étant avantageuse pour homogénéiser le ressenti du passage de vitesse sur le manche de changement de vitesse. Figure 2 is a perspective view of the mechanical transmission control device 4 according to the invention, in a preferred embodiment. The device 4 comprises the link 12 cooperating with the lever 8 or one of the levers of the gearbox (not shown). The rod 12 has two ends and comprises a metal body 24 (part framed dashed in the image) and a plastic overmoulding 26, the metal body 24 of the rod 12 being intended for increase the mass of the rod 12 to bring more inertia to the shift. On the top of the image can be seen a cable 16 of the cable system seen in connection with the previous figure. The cable 16 connects the device 4 to the control stick (not shown). The passage of speed is effected by the movement of the link 12, which can move over a distance of between 10mm and 30mm. The movement of the rod 12 may be generated by a system of return angle 18 so as to increase the force required for the passage of speed. The gearshift is made in this case by the rotation of the axis of the shift lever 8, the latter being able to pivot through the movement of the rod 12. A system of arrows on the image allows for visualize the direction of movement of the rod 12 and the pivoting generated on the axis of the speed lever 8, the embodiment shown does not limit other possible modes of movement of the lever. In this preferred embodiment, the mechanical connection 20 between the shift lever 8 and the link 12 is a ball joint. The mechanical connection 22 at the other end 30 of the rod may be a pivot connection or also a ball joint. Another rod (not shown) of the same type as the rod 12 can also cooperate with another lever (not shown) for controlling the gearbox, this measurement being advantageous for homogenizing the feel of the gearshift on the change stick. of speed.
La figure 3 est une vue de dessous de la biellette 12 conforme à l'invention et dans un autre mode de réalisation, la différence de réalisation étant dans la forme générale de la biellette au niveau de l'une 28 ou des extrémités 28 et 30 de la ou des biellette(s). On peut voir le corps métallique 24 et le surmoulage 26 de la biellette 12. Le surmoulage 26 en question forme à l'extrémité 28 de la biellette la liaison à rotule 20 destinée à s'engager avec le levier de vitesse. Le surmoulage peut également former une rotule 22 à l'autre extrémité 30 de la biellette. Ces liaisons à rotule 20 et 22 peuvent être réalisées par une cavité généralement sphérique formée dans le surmoulage, la cavité étant destinée à s'engager sur une sphère de forme correspondante sur le levier de vitesse. FIG. 3 is a view from below of the link 12 according to the invention and in another embodiment, the difference in embodiment being in the general shape of the link at one of the ends 28 and 30; the rod (s). The metal body 24 and the overmolding 26 of the rod 12 can be seen. The overmolding 26 in question forms at the end 28 of the link the ball joint 20 intended to engage with the gear lever. Overmolding may also form a ball 22 at the other end 30 of the rod. These ball joints 20 and 22 can be made by a generally spherical cavity formed in the overmoulding, the cavity being intended to engage a sphere of corresponding shape on the gear lever.
Le corps métallique 24 de la biellette 12 peut entourer la liaison à rotule 20 liée au levier de vitesse. Cette mesure est intéressante en ce que le volume supplémentaire de matériau métallique est à une distance moyenne « D » de la rotule 22 à partir de laquelle le mouvement de la biellette est engendré. En effet, cette distance « D »est favorable au surcroît d'inertie particulièrement en cas de pivotement de la biellette autour de la rotule 22. The metal body 24 of the rod 12 may surround the ball joint 20 connected to the gear lever. This measurement is interesting in that the additional volume of metallic material is at an average distance "D" of the ball 22 from which the movement of the rod is generated. Indeed, this distance "D" is favorable to the increased inertia especially in case of pivoting of the rod around the ball 22.
La surface de la section transversale de la biellette 12, section qui est indiquée sur l'image par le trait de coupe IV-IV, peut être croissante avec le rapprochement de la rotule 20 à l'extrémité 28 de la biellette 12, extrémité qui est opposée à celle 30 d'où est générée le mouvement. Cette mesure est intéressante en ce que la surface de section croissante engendre une masse croissante, son déport générant un surcroît d'inertie. Dans un mode préféré de réalisation, le corps métallique 24 entoure chacune des liaisons à rotule 20 et 22. Le corps métallique 24 peut être à base de fer ou de cuivre ou de nickel, il est favorablement de densité supérieure à 7. Le corps métallique peut être obtenu par moulage ou par frittage. La biellette 12 peut être d'une longueur comprise entre 40mm et 150mm. The surface of the cross section of the rod 12, which section is indicated on the image by the cut line IV-IV, may be increasing with the approach of the ball 20 to the end 28 of the rod 12, which end is opposite to that from which motion is generated. This measurement is interesting in that the surface of increasing section generates an increasing mass, its offset generating additional inertia. In a preferred embodiment, the metal body 24 surrounds each of the ball joints 20 and 22. The metal body 24 may be based on iron or copper or nickel, it is favorably with a density greater than 7. The metal body can be obtained by molding or sintering. The rod 12 may be of a length between 40mm and 150mm.
La figure 4 est une vue en coupe transversale IV-IV de la biellette 12. On peut voir sur cette section le corps en matériau métallique 24 et le surmoulage 26 en plastique sur le corps 24. Le surmoulage 26 peut être réalisé par un procédé d'injection. Le corps métallique 24 peut correspondre à plus de 50% de la surface de la section transversale de la biellette 12. Dans un mode préféré de réalisation le corps métallique correspond à plus de 70% de la surface de la section transversale de la biellette sur plus de 80% de la longueur de la biellette. FIG. 4 is a cross-sectional view IV-IV of the rod 12. This section shows the metal material body 24 and the plastic overmolding 26 on the body 24. The overmolding 26 can be made by a method of FIG. 'injection. The metal body 24 may correspond to more than 50% of the cross-sectional area of the link 12. In a preferred embodiment the metal body corresponds to more than 70% of the cross-sectional area of the connecting rod over 80% of the length of the link.
