Description

DISPOSITIF DE REGLAGE POUR COMMANDE MECANIQUE PAR CABLE, COMMANDE DE DEBRAYAGE ET VEHICULE AUTOMOBILE INCORPORANT CE DISPOSITIF La présente invention vise un dispositif de réglage pour commande mécanique par câble, une commande de débrayage et un véhicule incorporant ce dispositif.  The present invention relates to an adjustment device for mechanical control by cable, a disengagement control and a vehicle incorporating this device.
L'invention vise plus particulièrement les commandes à câble utilisées dans les véhicules automobiles du type dans lequel un câble interposé sur un parcours défini entre un organe de commande et un organe commandé peut coulisser dans un sens sous l'action de l'organe de commande afin d'actionner l'organe commandé.  The invention relates more particularly to the cable controls used in motor vehicles of the type in which a cable interposed on a path defined between a control member and a controlled member can slide in one direction under the action of the control member in order to actuate the controlled organ.
Dans un exemple typique, l'organe de commande est une pédale et l'organe commandé est un embrayage ou un frein de véhicule automobile.  In a typical example, the control member is a pedal and the controlled member is a clutch or a motor vehicle brake.
Le bon fonctionnement des commandes de débrayage nécessite un réglage de la précharge. Cette fonction de réglage est assurée actuellement par la pédale au moyen d'un ressort.  Proper operation of the clutch controls requires a preload adjustment. This adjustment function is currently provided by the pedal by means of a spring.
D'autre part, pour que la commande se fasse sans jeu, il est indispensable que le câble soit tendu. Cette tension est assurée au montage par un réglage approprié de la longueur du câble. Cependant, un jeu peut se créer avec le temps dans la commande, notamment en raison d'une modification de la longueur du câble sous l'effet des sollicitations répétées auxquelles il est soumis.  On the other hand, for control to be without play, it is essential that the cable is taut. This tension is ensured by fitting by a suitable adjustment of the length of the cable. However, a game can be created over time in the control, especially due to a change in the length of the cable under the effect of repeated solicitations to which it is subject.
En effet, on constate après l'installation d'une telle commande sur un véhicule et après un court temps d'utilisation que le câble tend à s'allonger sous l'effet des efforts de traction qui lui sont appliqués, tandis que la gaine tend à se raccourcir sous l'effet des efforts de compression qui lui sont appliqués en réaction. Ce rallongement du câble et le raccourcissement de la gaine s'ajoutent et provoquent également l'apparition de jeux parasites dans la chaîne de transmission de commande, qui sont nuisibles à un fonctionnement correct de la commande. Différentes solutions ont été proposées pour rattraper ce jeu par un dispositif automatique intégré au câble ou encore par un dispositif indépendant intégré au câble. Indeed, it is found after the installation of such a control on a vehicle and after a short time of use that the cable tends to elongate under the effect of the traction forces applied to it, while the sheath tends to shorten under the effect of compressive forces applied to it in reaction. This extension of the cable and the shortening of the sheath are added and also cause the appearance of stray games in the control transmission chain, which are detrimental to proper operation of the control. Various solutions have been proposed to make up for this game by an automatic device integrated in the cable or by an independent device integrated into the cable.
Le document US4263998 par exemple décrit un système d'ajustement de la longueur du câble d'embrayage sans avoir à le changer qui permet ainsi l'ajustement de la hauteur de la pédale.  Document US4263998 for example describes a system for adjusting the length of the clutch cable without having to change it, which thus makes it possible to adjust the height of the pedal.
Le document US4717004 décrit un système d'ajustement automatisé de la longueur du câble d'embrayage afin de compenser l'usure des plateaux d'embrayage.  US4717004 discloses an automated adjustment system of the length of the clutch cable to compensate for the wear of the clutch plates.
Cependant ces systèmes présentent un taux de défaillance important. However, these systems have a high failure rate.
De plus, il est nécessaire d'utiliser un dispositif indépendant pour assurer la fonction de précharge. In addition, it is necessary to use an independent device to provide the precharge function.
Par conséquent, les systèmes de l'art antérieur nécessitent des points multiples de fixation sur le pédalier, sur le support du pédalier et sur le câble. L'encombrement engendré est contraignant.  As a result, prior art systems require multiple attachment points on the crankset, the crank bracket and the cable. The generated space is constraining.
La présente invention vise à remédier à tout ou partie de ces inconvénients.  The present invention aims to remedy all or part of these disadvantages.
A cet effet, la présente invention a pour objet un dispositif de réglage pour commande mécanique par câble du type dans lequel un câble interposé sur un parcours défini entre un organe de commande et un organe commandé être déplacé dans un sens sous l'action de l'organe de commande afin d'actionner l'organe commandé, comprenant :  To this end, the subject of the present invention is an adjustment device for mechanical cable control of the type in which a cable interposed on a path defined between a control member and a member controlled to be moved in one direction under the action of the control member for actuating the controlled member, comprising:
- un support d'interface coopérant avec l'organe commandé,  an interface support cooperating with the controlled member,
- un moyen élastique,  an elastic means,
- une tige montée solidaire à une extrémité du câble,  a rod mounted integral with one end of the cable,
- une pièce coulissante apte à coulisser le long de la tige, le moyen élastique étant monté en appui contre la pièce coulissante et contre le support d'interface,  a sliding part able to slide along the rod, the elastic means being mounted in abutment against the sliding part and against the interface support,
- un corps de réglage coopérant avec la tige de manière à faire varier la longueur du câble en fonction des jeux apparaissant dans la commande. Grâce à cet agencement, le dispositif de réglage selon l'invention permet d'assurer à la fois la fonction de précharge et la fonction de réglage de la longueur du câble de commande. - An adjusting body cooperating with the rod so as to vary the length of the cable according to the games appearing in the command. Thanks to this arrangement, the adjustment device according to the invention makes it possible to ensure both the precharge function and the function for adjusting the length of the control cable.
La présente invention permet ainsi de résoudre le problème de l'encombrement engendré par la fixation de plusieurs dispositifs sur la commande mécanique par câble, tout en offrant un dispositif performant de réglage de la longueur du câble.  The present invention thus makes it possible to solve the problem of the space generated by the fixing of several devices on the mechanical control cable, while providing a powerful device for adjusting the length of the cable.
La mise en œuvre de la présente invention comporte plusieurs avantages, notamment cela permet d'éviter les risques d'interférence entre les divers dispositifs remplacés par le dispositif selon l'invention et les pièces et faisceaux voisins.  The implementation of the present invention has several advantages, in particular it avoids the risk of interference between the various devices replaced by the device according to the invention and the neighboring parts and beams.
Un autre avantage du dispositif selon l'invention est qu'il permet un gain important en temps de montage et une simplification de la logistique car il y a moins des pièces à gérer. En effet, l'invention permet de remplacer un support pour attacher le ressort soudé sur la pédale et un support pour attacher le ressort soudé sur le support de pédalier par le montage d'un seul dispositif au lieu des deux dispositifs actuellement montés séparément.  Another advantage of the device according to the invention is that it allows a significant gain in assembly time and simplification of logistics because there are fewer parts to manage. Indeed, the invention allows to replace a support for attaching the welded spring on the pedal and a support for attaching the welded spring on the bottom bracket by mounting a single device instead of the two devices currently mounted separately.
Enfin, un avantage supplémentaire de l'invention est que le dispositif selon l'invention permet d'avoir un levier de commande ayant une hauteur constante ce qui permet d'équiper le levier de commande par différents capteurs. Ceci est important pour les pédales devant être équipées par des capteurs de positions par exemple.  Finally, an additional advantage of the invention is that the device according to the invention allows to have a control lever having a constant height which allows to equip the control lever by different sensors. This is important for pedals to be equipped with position sensors for example.
On note que la pédale de débrayage est un levier de commande.  Note that the clutch pedal is a control lever.
Dans le cas d'une pédale de débrayage notamment, cela permet d'équiper la pédale par différents capteurs nécessaires aux fonctions de dépollution et de Start - Stop.  In the case of a clutch pedal in particular, it allows to equip the pedal by different sensors necessary for the functions of depollution and Start - Stop.
Selon une réalisation, le coulissement de la pièce coulissante est limité par un jeu associé au support d'interface.  According to one embodiment, the sliding of the sliding part is limited by a game associated with the interface support.
Selon une réalisation, la pièce coulissante est plaquée contre le corps de réglage.  In one embodiment, the slider is pressed against the adjusting body.
Selon une réalisation, la tige est filetée et le corps de réglage est percé et taraudé de manière à faire varier la longueur du câble par des rotations du corps de réglage autour de la tige filetée. Selon une réalisation, le moyen élastique est installé autour de la tige. In one embodiment, the rod is threaded and the adjusting body is drilled and tapped so as to vary the length of the cable by rotations of the adjusting body around the threaded rod. In one embodiment, the elastic means is installed around the rod.
Selon une réalisation, le moyen élastique est un ressort de compression. In one embodiment, the elastic means is a compression spring.
La présente l'invention a aussi pour objet, une commande de débrayage par câble comprenant un dispositif objet de l'invention tel que décrit ci-dessus.  The present invention also relates to a cable release control comprising a device object of the invention as described above.
Selon des caractéristiques particulières, la commande de débrayage par câble comprend un dispositif de réglage objet de l'invention installé à l'extrémité du câble de commande du côté de la fourchette d'embrayage.  According to particular features, the cable clutch control comprises an adjustment device object of the invention installed at the end of the control cable on the side of the clutch fork.
Enfin, la présente invention a pour objet un véhicule automobile comprenant une commande mécanique par câble équipée d'un dispositif objet de l'invention tel que décrit ci-dessus.  Finally, the present invention relates to a motor vehicle comprising a mechanical control cable equipped with a device according to the invention as described above.
Les avantages, buts et caractéristiques particulières de ce procédé et de ces applications étant similaires à ceux du dispositif objet de la présente invention, ils ne sont pas rappelés ici.  Since the advantages, aims and particular characteristics of this method and of these applications are similar to those of the device that is the subject of the present invention, they are not recalled here.
D'autres avantages, buts et caractéristiques de l'invention apparaîtront à la lecture de la description suivante, donnée à titre d'exemple nullement limitatif, et faite en se référant aux figures dans lesquelles:  Other advantages, aims and features of the invention will appear on reading the following description, given by way of non-limiting example, and with reference to the figures in which:

La figure 1 illustre un dispositif de commande d'un câble de débrayage, selon un mode de réalisation de l'invention.  Figure 1 illustrates a control device of a release cable, according to one embodiment of the invention.
La présente invention permet de résoudre le problème de l'encombrement engendré par la fixation de plusieurs dispositifs sur la commande mécanique par câble par la mise en œuvre d'un dispositif de réglage permettant à la fois d'assurer la fonction de précharge du système de commande et la fonction de réglage de la longueur du câble. Le dispositif de réglage selon l'invention peut être utilisé pour équiper une commande de débrayage par câble d'un véhicule automobile, comme le montre la Figure 1 . The present invention makes it possible to solve the problem of the bulk generated by the fixing of several devices on the mechanical cable control by the implementation of an adjustment device making it possible at the same time to perform the precharging function of the control system. control and function of adjusting the length of the cable. The adjusting device according to the invention can be used to equip a cable release control of a motor vehicle, as shown in Figure 1.
Dans ce mode de réalisation, la commande de débrayage 10 comporte une pédale 14 de débrayage qui est l'organe de commande, reliée par un câble 13 entouré d'une gaine flexible à une fourchette d'embrayage 26. Lorsque la pédale 14 de débrayage est actionnée, le câble 13 peut coulisser dans un sens afin d'actionner la fourchette d'embrayage 26.  In this embodiment, the clutch control 10 comprises a clutch pedal 14 which is the control member, connected by a cable 13 surrounded by a flexible sheath to a clutch fork 26. When the clutch pedal 14 is actuated, the cable 13 can slide in one direction in order to actuate the clutch fork 26.
Le dispositif 1 1 de réglage selon l'invention est installé du côté de la fourchette d'embrayage 26 et il est relié à celle-ci par l'une de ses extrémités.  The device 1 1 of adjustment according to the invention is installed on the side of the clutch fork 26 and is connected thereto by one of its ends.
Un mode de mise en œuvre du dispositif 1 1 de réglage pour équiper une commande de débrayage 10 est détaillé dans les Figures 2 et 3.  An embodiment of the adjustment device 1 1 to equip a clutch control 10 is detailed in Figures 2 and 3.
A l'extrémité du câble 13 de débrayage située du coté de la fourchette d'embrayage 26, une tige filetée 21 est montée solidaire à une de ses extrémités du câble 13. Sur cette tige 21 sont installés un ressort 23 à spirales et un corps de réglage 25 percé et taraudé.  At the end of the release cable 13 located on the side of the clutch fork 26, a threaded rod 21 is mounted integral with one of its ends of the cable 13. On this rod 21 are installed a spiral spring 23 and a body setting 25 pierced and tapped.
Un support 22 d'interface avec la fourchette d'embrayage 26 est porteur de l'ensemble du dispositif et assure l'ancrage de la commande et du dispositif 1 1 de réglage dans la fourchette d'embrayage 26.  A support 22 interfacing with the clutch fork 26 carries the entire device and ensures the anchoring of the control and the device 1 1 of adjustment in the clutch fork 26.
En d'autres termes, les pièces du dispositif sont intégrées et montées dans le support d'interface 22. Un côté du support d'interface 22 est ancré dans la fourchette d'embrayage 26. L'autre côté de ce support 22 sert de face d'appui contre le ressort 23 et assure l'interface avec le câble de commande 13 et la tige filetée 21 .  In other words, the parts of the device are integrated and mounted in the interface support 22. One side of the interface support 22 is anchored in the clutch fork 26. The other side of this support 22 serves as bearing surface against the spring 23 and provides the interface with the control cable 13 and the threaded rod 21.
De plus, ce support 22 assure également un jeu 37 facilitant le fonctionnement de la pièce coulissante 24, comme le montre la Figure 3.  In addition, this support 22 also provides a clearance 37 facilitating the operation of the slider 24, as shown in Figure 3.
Cette pièce coulissante 24, apte à coulisser le long de la tige 21 , est en appui contre le corps de réglage 25 et assure les interfaces par rapport à la tige 21 et par rapport au support 22.  This sliding piece 24, slidable along the rod 21, bears against the adjustment body 25 and provides the interfaces with respect to the rod 21 and relative to the support 22.
Le ressort 23 est enroulé autour de la tige 21 et comprimé entre la pièce coulissante 24 et le support d'interface 22.  The spring 23 is wound around the rod 21 and compressed between the sliding piece 24 and the interface support 22.
On note que le ressort de compression 23 constitue dans cet exemple le moyen élastique qui permet au dispositif objet de l'invention d'assurer la fonction de précharge de la commande de débrayage. En variante, le ressort 26 peut-être un ressort de traction ou bien encore un ressort de torsion. Note that the compression spring 23 is in this example the elastic means that allows the device object of the invention to ensure the preload function of the clutch control. Alternatively, the spring 26 may be a tension spring or a torsion spring.
Le corps de réglage 25 est taraudé ce qui lui permet de coopérer avec la tige 21 filetée de manière à régler la longueur du câble en fonction des jeux apparaissant dans la commande de débrayage.  The adjusting body 25 is threaded which allows it to cooperate with the threaded rod 21 so as to adjust the length of the cable according to the clearances appearing in the clutch control.
En effet, le corps de réglage 25 est apte à tourner autour de la tige filetée 21 , ce qui permet de serrer ou de desserrer la pièce coulissante 24 et le ressort de compression 23 et, par conséquent, de tendre ou de détendre le câble selon les besoins.  Indeed, the adjusting body 25 is able to rotate around the threaded rod 21, which allows to tighten or loosen the sliding piece 24 and the compression spring 23 and, consequently, to stretch or relax the cable according to needs.
En d'autres termes, si des jeux apparaissent dans la commande et qu'il devient nécessaire de tendre le câble 13, le corps de réglage 25 tourne pour serrer la pièce coulissante 24 contre le ressort 23. Le ressort 23 se trouve alors comprimé par la pièce coulissante 24 et le support d'interface 22. Or ce dernier est bloqué car il est ancré dans la fourchette d'embrayage 26. Par conséquent le câble 13 est tendu et la pédale remonte ce qui permet d'obtenir la hauteur de pédale de débrayage souhaitée.  In other words, if gaps appear in the control and it becomes necessary to tension the cable 13, the adjusting body 25 rotates to tighten the sliding member 24 against the spring 23. The spring 23 is then compressed by the sliding part 24 and the interface support 22. The latter is blocked because it is anchored in the clutch fork 26. Therefore the cable 13 is stretched and the pedal goes up which allows to obtain the pedal height desired release.
D'une manière analogue, lorsqu'il est nécessaire de détendre le câble 13, le corps de réglage 25 tourne de manière à desserrer la pièce coulissante 24. Ainsi, le ressort 23 se détend et pousse la pièce coulissante 24 ce qui permet au câble de se détendre. La pédale 14 va adopter alors une position plus basse correspondant à la hauteur recherchée pour le bon fonctionnement de la commande de débrayage.  In a similar way, when it is necessary to relax the cable 13, the adjusting body 25 rotates so as to loosen the sliding part 24. Thus, the spring 23 relaxes and pushes the sliding part 24 which allows the cable to relax. The pedal 14 will then adopt a lower position corresponding to the desired height for the proper operation of the clutch control.
Le dispositif 1 1 selon l'invention peut fonctionner correctement jusqu'à la fin de vie de l'embrayage. Cependant, pour améliorer l'agrément de conduite, la longueur de câble peut être réglée manuellement à des intervalles réguliers. Le réglage manuel du câble peut par exemple être effectué tous les 40 000 où 50 000 km.  The device 1 1 according to the invention can function properly until the end of life of the clutch. However, to improve driveability, the cable length can be adjusted manually at regular intervals. The manual adjustment of the cable can for example be performed every 40 000 or 50 000 km.
On note qu'il est possible d'utiliser d'autres dispositifs de réglage.  Note that it is possible to use other adjustment devices.
La figure 4 illustre un autre mode de réalisation de l'invention.  Figure 4 illustrates another embodiment of the invention.
A l'extrémité du câble 13 de débrayage située du coté de la fourchette d'embrayage 26, une tige filetée 41 est montée solidaire à une de ses extrémités du câble 13. Dans ce mode de réalisation, le dispositif 1 1 objet de l'invention comprend un ressort 43 de torsion assurant la fonction de précharge et un corps de réglage 45 installés sur la tige 41 . At the end of the clutch cable 13 located on the side of the clutch fork 26, a threaded rod 41 is mounted integral with one of its ends of the cable 13. In this embodiment, the device 1 1 object of the invention comprises a torsion spring 43 providing the precharge function and a control body 45 installed on the rod 41.
Un support 42 d'interface avec la fourchette d'embrayage 26 est porteur de l'ensemble du dispositif et assure l'ancrage de la commande et du dispositif 1 1 de réglage dans la fourchette d'embrayage 26.  A support 42 interfacing with the clutch fork 26 carries the entire device and ensures the anchoring of the control and the device 1 1 of adjustment in the clutch fork 26.
La pièce coulissante 44 est un corps cylindrique apte à coulisser le long de la tige 41 . La pièce 44 est en appui contre le corps de réglage 45 et assure les interfaces par rapport à la tige 41 et par rapport au support 42.  The sliding part 44 is a cylindrical body able to slide along the rod 41. The piece 44 bears against the adjustment body 45 and provides the interfaces with respect to the rod 41 and relative to the support 42.
Le support 42 assure un jeu 47 facilitant le fonctionnement de la pièce coulissante 44.  The support 42 provides a clearance 47 facilitating the operation of the sliding part 44.
Le fait d'équiper la commande de débrayage d'un dispositif de réglage de la longueur du câble 13 de commande qui assure aussi la précharge du système tel que décrit ci-dessus permet de résoudre la problème de l'encombrement généré par la fixation de plusieurs dispositifs indépendants pour régler ces deux fonctions tout en apportant des gains en temps de montage.  Equipping the disengagement control with a device for adjusting the length of the control cable 13 which also ensures the precharging of the system as described above makes it possible to solve the problem of the space generated by the fixing of the several independent devices to adjust these two functions while providing gains in mounting time.
