Description

DISPOSITIF POUR LA COMMANDE D'UNE BOITE DE VITESSES ET D'UN FREIN DE STATIONNEMENT D'UN VEHICULE AUTOMOBILE AU MOYEN D'UN LEVIER DE MANŒUVRE  DEVICE FOR CONTROLLING A GEARBOX AND A PARKING BRAKE OF A MOTOR VEHICLE USING A LEVER FOR MANEUVER
COMMUN.  COMMON.
L'invention se rattache au secteur technique des équipements pour véhicules automobiles et concerne plus particulièrement un dispositif pour la commande d'une boite de vitesses et d'un frein de stationnement au moyen du même levier de manœuvre. The invention relates to the technical sector of equipment for motor vehicles and relates more particularly to a device for controlling a gearbox and a parking brake using the same operating lever.
Généralement, un véhicule automobile présente, de manière séparée, un levier de commande pour la sélection et le passage des vitesses et un levier agissant le plus souvent sur un câble afin d'actionner un frein de stationnement. Le levier de vitesses est monté avec capacité de déplacement multidirectionnel au moyen d'une articulation sphérique, dans un support fixé sur le plancher ou la planche de bord du véhicule. L'extrémité inférieure du levier, connue sous le nom de pied de levier, est agencée pour être accouplée à des organes de passage et de sélection de vitesses. On a proposé également d'assurer ces deux fonctions, à savoir ; le passage et la sélection des vitesses d'une part, et l'actionnement du frein de stationnement d'autre part, au moyen du même levier de manœuvre. Une solution de ce type ressort par exemple de l'enseignement du brevet EP 2163793 dont le demandeur de la présente est également titulaire. Generally, a motor vehicle has, separately, a control lever for selecting and shifting and a lever acting most often on a cable to actuate a parking brake. The shift lever is mounted with multidirectional displacement capability by means of a ball joint, in a bracket fixed to the floor or dashboard of the vehicle. The lower end of the lever, known as the lever foot, is arranged to be coupled to the passage members and gear selection. It has also been proposed to provide these two functions, namely; the passage and selection of speeds on the one hand, and the actuation of the parking brake on the other hand, by means of the same operating lever. A solution of this type emerges, for example, from the teaching of patent EP 2163793 which the applicant hereof also holds.
La solution technique décrite dans ce brevet donne satisfaction mais est limitée à des véhicules qui ne sont pas équipés d'un système de verrouillage de la marche arrière, par exemple au moyen d'une gâchette escamotable coopérant avec une butée. Tout au contraire, selon l'enseignement de ce brevet, on utilise une gâchette montée sur le levier de commande pour assurer la fonction de commande du frein de stationnement. On observe également que durant l'enclenchement de la fonction frein de stationnement, il n'est plus possible d'assurer la fonction de sélection et de passage d'une vitesse. A noter également que les différents mouvements qu'il est nécessaire d'appliquer sur le levier, ne sont pas ergonomiques. The technical solution described in this patent is satisfactory but is limited to vehicles that are not equipped with a reverse locking system, for example by means of a retractable trigger cooperating with a stop. On the contrary, according to the teaching of this patent is used a trigger mounted on the control lever to provide the parking brake control function. It is also observed that during the activation of the parking brake function, it is no longer possible to perform the function of selecting and passing a speed. Note also that the different movements that it is necessary to apply on the lever, are not ergonomic.
L'invention s'est fixée pour but de remédier à ces inconvénients d'une manière simple, sûre, efficace et rationnelle. Le problème que se propose de résoudre l'invention est de pouvoir utiliser le même levier de manœuvre pour assurer à la fois la fonction de passage et de sélection de vitesses et la fonction d'actionnement du frein de stationnement, avantageusement dans le cas où le levier est équipé d'une gâchette de verrouillage sur la marche arrière.  The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner. The problem to be solved by the invention is to be able to use the same operating lever to ensure both the function of passage and selection of speeds and the function of actuating the parking brake, advantageously in the case where the lever is equipped with a locking trigger on the reverse gear.
Pour résoudre un tel problème il a été conçu et mis au point un dispositif pour la commande d'une boîte de vitesses et d'un frein de stationnement au moyen, d'une manière connue, d'un levier de manœuvre commun, ledit levier présentant une gâchette escamotable à rencontre d'une butée pour le passage de la marche arrière, le levier étant assujetti à des moyens pour être commuté d'une position permettant le passage et la sélection de vitesses à une autre position pour l'actionnement du frein de stationnement avec possibilité de sélectionner et passer une vitesse, le pied de levier présentant un corps sphérique monté avec capacité de déplacement multidirectionnel dans un support, en étant agencé pour le passage et la sélection de vitesses. To solve such a problem it has been designed and developed a device for controlling a gearbox and a parking brake by means, in known manner, of a common operating lever, said lever having a retractable trigger against an abutment for the passage of reverse, the lever being subject to means for being switched from a position permitting passage and selection of gears to another position for actuating the brake parking with possibility to select and pass a speed, the lever foot having a spherical body mounted with multidirectional displacement capacity in a support, being arranged for the passage and selection of speeds.
Selon l'invention, compte tenu du problème posé à résoudre, le corps sphérique présente, dans sa partie médiane, un disque monté libre en rotation dans un plan vertical et traversé par l'extrémité du levier avec capacité de coulissement à rencontre d'un organe élastique, ladite extrémité présentant un organe d'accouplement temporaire entre le disque et le corps sphérique, ledit organe étant apte à coopérer, sous un effort d'appui exercé sur le levier, avec un chariot assujetti à un câble relatif au frein de stationnement, ledit chariot étant déplaçable dans le support dans lequel est monté le corps sphérique, pour provoquer sous un effet de déplacement angulaire du levier, un déplacement dudit chariot et dudit support, pour exercer une force de traction sur le câble, le déplacement angulaire dudit support mettant en prise un système de dentures avec un cliquet escamotable afin de bloquer l'effort de traction sur le câble, le levier étant rappelé en position d'accouplement du disque et du corps par l'organe élastique pour permettre le passage éventuel d'une vitesse. II résulte donc de ces dispositions qu'il est possible de conserver la gâchette de verrouillage de la marche arrière avec, en plus, la possibilité, en position frein de stationnement actionné de passer une vitesse à savoir la première par exemple où la marche arrière pour faciliter par exemple un démarrage en côte. According to the invention, given the problem to be solved, the spherical body has, in its middle part, a rotatably mounted disk in a vertical plane and traversed by the end of the lever with sliding capacity against an elastic member, said end having a temporary coupling member between the disk and the spherical body, said member being adapted to cooperate, under a pressing force exerted on the lever, with a carriage secured to a cable relative to the parking brake, said carriage being movable in the support in which is mounted the spherical body, to cause under the effect of angular displacement of the lever, a displacement said carriage and said support, for exerting a traction force on the cable, the angular displacement of said support engaging a gear system with a retractable pawl to block the tensile force on the cable, the lever being biased into position coupling the disk and the body by the elastic member to allow the possible passage of a speed. It follows therefore from these provisions that it is possible to keep the locking trigger of the reverse gear with, in addition, the possibility, in the parking brake position to move a speed namely the first example where the reverse gear for for example to facilitate a hill start.
Pour résoudre le problème posé de pouvoir utiliser le levier de manœuvre soit pour la commande de sélection de passage de vitesses, soit pour la commande du frein de stationnement, l'organe d'accouplement temporaire entre le disque et le corps sphérique est constitué par une embase hémisphérique présentant une portée méplate circulaire apte à coopérer avec une empreinte complémentaire que présente le disque et un corps sphérique, ladite embase présentant un doigt d'accouplement avec le chariot. Pour résoudre le problème posé d'assurer le déplacement du chariot en vue d'exercer un effort de traction sur le câble, le chariot est monté avec capacité de déplacement angulaire dans deux lumières en arc de cercle formées dans l'épaisseur de flasques latéraux que présente le support qui a sensiblement la forme d'une coquille. To solve the problem of being able to use the operating lever for the shifting selection control or for controlling the parking brake, the temporary coupling member between the disk and the spherical body is constituted by a hemispherical base having a flat flat surface capable of cooperating with a complementary cavity that the disk and a spherical body, said base having a coupling finger with the carriage. To solve the problem of ensuring the displacement of the carriage in order to exert a tensile force on the cable, the carriage is mounted with angular displacement capacity in two arcuate slots formed in the thickness of lateral flanges that presents the support which has substantially the shape of a shell.
Pour résoudre le problème posé d'exercer sur le levier de manœuvre un effort plus important pour l'actionnement du frein de stationnement que pour le déplacement nécessaire au passage et à la sélection d'une vitesse, le chariot est assujetti à un ressort de rappel en position de traction du câble de frein de stationnement. To solve the problem of exerting on the operating lever a greater effort for the actuation of the parking brake than for the movement necessary for the passage and the selection of a speed, the carriage is subject to a return spring in the traction position of the parking brake cable.
Selon une autre caractéristique, pour assurer le blocage en position de traction du câble du frein de stationnement, le système de denture est constitué par un secteur denté formé en débordement de la base de l'un des flasques du support. According to another characteristic, to ensure the locking in the traction position of the parking brake cable, the tooth system is constituted by a toothed sector formed in overflow of the base of one of the flanges of the support.
Selon d'autres caractéristiques, le pied de levier est monté pivotant dans une platine en combinaison avec des éléments d'accouplement reliés aux câbles de sélection et de passage des vitesses. According to other features, the lever foot is pivotally mounted in a plate in combination with coupling elements connected to the selection and shifting cables.
Le ressort de rappel du chariot est accouplé à la platine.  The return spring of the carriage is coupled to the plate.
La butée de marche arrière est formée en débordement de la platine pour coopérer avec la gâchette du levier apte à être escamotée à rencontre d'un organe élastique pour échapper ladite butée correspondant au passage de la marche arrière sous un effet de basculement angulaire dudit levier.  The reverse stop is formed by overflow of the plate to cooperate with the trigger of the lever adapted to be retracted against a resilient member to escape said stop corresponding to the passage of the reverse under an angular tilting effect of said lever.
Pour résoudre le problème posé de relâcher le frein de stationnement, le cliquet est assujetti à des moyens pour être escamoté et rappelé en position de coopération avec le secteur denté du support. Dans une autre forme de réalisation, l'extrémité du levier est monté avec capacité de coulissement guidé dans un trou débouchant formé verticalement dans l'épaisseur du disque, en étant rappelé en position d'accouplement par un ressort monté dans un chambrage coaxial audit trou. To solve the problem of releasing the parking brake, the pawl is subject to means to be retracted and recalled to the position of cooperation with the toothed sector of the support. In another embodiment, the end of the lever is mounted with sliding capacity guided in a through hole formed vertically in the thickness of the disk, being returned to the coupling position by a spring mounted in a recess coaxial with said hole .

Le corps sphérique (2) présente, de manière sensiblement perpendiculaire au levier (1), un doigt d'accouplement (5) pour le montage d'un élément de renvoi et de sélection des vitesses (6) assujetti par exemple à un câble ou une tringle de commande (7). Le levier (1) coopère avec un élément (8) relié à un câble (9) pour le passage des vitesses sélectionnées. Ces différentes dispositions ne sont pas décrites en détail car parfaitement connues pour un homme du métier et susceptibles de faire l'objet de différentes formes de réalisations. De même, le levier (1) est équipé d'une gâchette (10) montée à l'encontre d'un ressort (1 1) assurant la fonction, de manière connue pour un homme du métier de verrouillage de la marche arrière. Cette gâchette (1 1) coopère avec une butée (12) que présente la platine (4). Comme le montrent les figures 8, et 9, pour la sélection des vitesses (1 et 2) par exemple, la gâchette (10) est en position de butée avec l'élément (12), figure 8, tandis que pour le passage de la marche arrière, la gâchette (10) est escamotée vers le haut par exemple, afin d'échapper la butée (12) pour la sélection de la marche arrière, figure 9. The spherical body (2) has, in a manner substantially perpendicular to the lever (1), a coupling pin (5) for mounting a deflection and gear selection element (6) secured for example to a cable or a control rod (7). The lever (1) cooperates with an element (8) connected to a cable (9) for the passage of the selected speeds. These various provisions are not described in detail because they are well known to a person skilled in the art and capable of being the subject of various embodiments. Similarly, the lever (1) is equipped with a trigger (10) mounted against a spring (1 1) providing the function, in a manner known to a person skilled in the art of locking the reverse gear. This trigger (1 1) cooperates with a stop (12) that the platen (4). As shown in FIGS. 8 and 9, for the selection of the speeds (1 and 2) for example, the trigger (10) is in the abutment position with the element (12), FIG. 8, while for the passage of the reverse, the trigger (10) is retracted for example, to escape the stop (12) for the selection of reverse, Figure 9.
C'est à partir de ce type de dispositif comprenant un levier (1) équipé d'une gâchette de verrouillage de la marche arrière, que ledit levier présente notamment au niveau de son extrémité constituant le pied de levier, différents moyens et agencements aptes à permettre sous l'effet de certains déplacements dudit levier, soit la sélection et le passage des vitesses, soit l'actionnement du frein de stationnement avec, lorsque ce dernier est actionné, la possibilité de passer au moins une vitesse (1ère ou marche arrière généralement). It is from this type of device comprising a lever (1) equipped with a reverse locking trigger, that said lever has in particular at its end constituting the lever foot, different means and arrangements adapted to allow under the effect of certain movements of said lever, the selection and shifting, or the actuation of the parking brake with, when the latter is actuated, the possibility of passing at least one speed (1st or reverse generally ).
Selon l'invention, le corps sphérique (2) qui constitue une articulation à rotule, pour un déplacement multidirectionnel du levier (1), présente, dans sa partie médiane, un disque (13) monté libre en rotation dans un plan vertical. Autrement dit, l'axe de rotation du disque (13) est disposé orthogonalement à l'axe du levier (1). L'extrémité inférieure du levier (1) est engagée à libre coulissement dans l'épaisseur du disque (13) à l'encontre d'un organe élastique (14) sous forme, par exemple, d'un ressort. Dans une forme de réalisation, l'extrémité de levier (1) est montée avec capacité de coulissement guidé dans un trou débouchant formé verticalement dans l'épaisseur du disque (13) en étant rappelé en position par le ressort (14) monté dans un chambrage coaxial audit trou. De manière importante, l'extrémité libre du levier (1), présente un organe d'accouplement temporaire (15) entre le disque (13) et le corps sphérique (2). Comme le montrent les figures des dessins, l'organe d'accouplement (15), est constitué par une embase hémisphérique (15) présentant une portée méplate circulaire (15a) apte à coopérer avec une empreinte ou évidement complémentaire (16) que présente le disque (13) et le corps sphérique (2). Lorsqu'aucun effort d'appui n'est exercé sur le levier (1), l'embase hémisphérique (15) est rappelée en position par le ressort (14), de manière à être positionné dans l'empreinte (16). Dans cette position d'accouplement du disque (13) et du corps sphérique (2), un déplacement angulaire dans un sens quelconque du levier (1) provoque, de manière concomitante le déplacement de l'ensemble corps sphérique (2) / disque (13) pour par exemple la sélection et le passage des vitesses, d'une manière classique. According to the invention, the spherical body (2) which constitutes a ball joint, for a multidirectional movement of the lever (1), has, in its middle part, a disc (13) mounted free to rotate in a vertical plane. In other words, the axis of rotation of the disc (13) is disposed orthogonally to the axis of the lever (1). The lower end of the lever (1) is engaged in free sliding in the thickness of the disc (13) against a resilient member (14) in the form, for example, of a spring. In one embodiment, the lever end (1) is mounted with slidability guided in a through hole formed vertically in the thickness of the disk (13) being biased in position by the spring (14) mounted in a coaxial chambering in said hole. Importantly, the free end of the lever (1), has a temporary coupling member (15) between the disk (13) and the spherical body (2). As shown in the drawing figures, the coupling member (15) is constituted by a hemispherical base (15) having a circular flattened bearing surface (15a) adapted to cooperate with a recess or complementary recess (16) that the disc (13) and the spherical body (2). When no pressing force is exerted on the lever (1), the hemispherical base (15) is biased into position by the spring (14), so as to be positioned in the cavity (16). In this coupling position of the disc (13) and the spherical body (2), an angular displacement in any direction of the lever (1) causes, concomitantly, the displacement of the spherical body (2) / disc ( 13) for example selection and shifting in a conventional manner.
Selon une autre caractéristique importante de l'invention, l'organe d'accouplement temporaire (15) présente un doigt transversal (17) apte à coopérer, en position d'accouplement, avec un chariot mobile (18). Le chariot (18) est monté avec capacité de déplacement angulaire dans deux lumières en arc de cercle (3a) et (3b) formées dans l'épaisseur de flasques latéraux (3c) et (3d) que présente le support (3) qui a sensiblement la forme d'une coquille. Le chariot (18) est accouplé à un câble (19) relatif au frein de stationnement. Un ressort (20), accouplé entre le chariot (18) et une partie de la platine (4), assure le rappel en position dudit chariot comme il sera indiqué dans la suite de la description. According to another important feature of the invention, the temporary coupling member (15) has a transverse finger (17) adapted to cooperate, in coupling position, with a movable carriage (18). The carriage (18) is mounted with angular displacement capacity in two arcuate openings (3a) and (3b) formed in the thickness of lateral flanges (3c) and (3d) that the support (3) which has substantially the shape of a shell. The carriage (18) is coupled to a cable (19) relative to the parking brake. A spring (20), coupled between the carriage (18) and a portion of the plate (4), ensures the return position of said carriage as will be indicated in the following description.
En position d'accouplement de l'extrémité intérieure du levier (1) dans le chariot (18) au moyen du doigt (17), un déplacement angulaire dudit levier provoque le déplacement du chariot (18) et du support (3a), ce qui exerce, par conséquent, une force de traction sur le câble (19). In the coupling position of the inner end of the lever (1) in the carriage (18) by means of the finger (17), an angular displacement of said lever causes the carriage (18) and the support (3a) to move, thereby exerting a pulling force on the cable (19).
Le déplacement angulaire du support (3) a pour effet de mettre en prise un système de dentures (21) avec un cliquet escamotable (22) afin de bloquer l'effort de traction sur le câble (19). Ce système de dentures (21) est constitué par exemple par un secteur denté formé en débordement de la base de l'un des flasques du support (3).  The angular displacement of the support (3) has the effect of engaging a tooth system (21) with a retractable ratchet (22) to block the tensile force on the cable (19). This tooth system (21) is constituted for example by a toothed sector formed in overflow of the base of one of the flanges of the support (3).
Il convient d'analyser le positionnement du dispositif en référence aux figures 2 à 7 notamment : It is necessary to analyze the positioning of the device with reference to FIGS. 2 to 7, in particular:
A la figure 2, le dispositif est représenté en position du levier (1) pour le passage et la sélection des vitesses, le frein de stationnement n'étant pas actionné, aucun effort de traction n'est exercé sur le câble (19). Dans cette position, le disque (13) et le corps sphérique (2) sont accouplés par l'organe (15) logé dans les empreintes (16) de l'ensemble du corps sphérique (2-13). Le levier (1) peut par conséquent être soumis à différents déplacements angulaires pour la sélection et le passage des vitesses en considérant que l'accouplement du corps (2) et du disque (13) fait office de rotule. Dans cette position, le doigt (17) n'est pas accouplé au chariot (18). Le levier (4) est maintenu dans cette position d'accouplement sous l'effet de détente du ressort (14).  In Figure 2, the device is shown in the position of the lever (1) for the passage and selection of speeds, the parking brake is not actuated, no tensile force is exerted on the cable (19). In this position, the disc (13) and the spherical body (2) are coupled by the member (15) housed in the indentations (16) of the entire spherical body (2-13). The lever (1) can therefore be subjected to different angular displacements for selection and shifting considering that the coupling of the body (2) and the disk (13) serves as a ball joint. In this position, the finger (17) is not coupled to the carriage (18). The lever (4) is held in this coupling position under the spring release effect (14).
Lorsqu'un appui digital, notamment vertical, est exercé sur le levier (1), le ressort (14) est comprimé et l'organe d'accouplement (15) échappe les empreintes (16). Le doigt (17) s'engage dans une empreinte complémentaire du chariot (18), figure 3. When a digital support, in particular vertical, is exerted on the lever (1), the spring (14) is compressed and the coupling member (15) escapes the fingerprints (16). The finger (17) engages in a complementary cavity of the carriage (18), FIG.
Dans cette position de désaccouplement du disque (13) et du corps (2) et d'accouplement dudit disque avec le chariot (18), un déplacement angulaire du levier (1) provoque, de manière concomitante, le déplacement angulaire du chariot (18) et le pivotement angulaire du support (3), figure4. In this position of disconnection of the disc (13) and the body (2) and coupling of said disc with the carriage (18), a displacement angle of the lever (1) causes, concomitantly, the angular displacement of the carriage (18) and the angular pivoting of the support (3), FIG.
Dans cette position, sous l'effet de déplacement angulaire du chariot et du support (3), le câble (19) du frein de stationnement, est soumis à une force d'attraction correspondant à l'actionnement dudit frein.  In this position, under the effect of angular displacement of the carriage and the support (3), the cable (19) of the parking brake is subjected to an attraction force corresponding to the actuation of said brake.
Toujours dans cette position, le secteur denté (21) vient en prise avec le cliquet (22) afin de maintenir cette position de traction sur le câble de frein (figure 4). Le ressort (20) est également soumis à un effort de traction.  Still in this position, the sector gear (21) engages with the pawl (22) to maintain this traction position on the brake cable (Figure 4). The spring (20) is also subjected to a tensile stress.
Lorsqu'on relâche le levier (1), le ressort (20) ramène automatiquement le chariot (18) en position initiale en alignement de l'organe d'accouplement (15) avec les empreintes (16), figure 5.  When releasing the lever (1), the spring (20) automatically returns the carriage (18) to the initial position in alignment with the coupling member (15) with the fingerprints (16), FIG. 5.
En relâchant l'effort d'appui exercé sur le levier (1), le ressort (14) ramène automatiquement ledit levier, en position d'accouplement de l'organe (15) avec l'empreinte (16), figure 6. Dans cette position, où le frein de stationnement est toujours actionné suite à l'effort de traction exercé sur le câble (la) en maintenant en position angulaire le support (3) dont le secteur denté (21) est en prise avec le cliquet (22), il est tout à fait possible de sélectionner et d'engager une vitesse (la première ou la marche arrière par exemple), le disque n'étant plus accouplé avec le chariot, figure 6.  By releasing the support force exerted on the lever (1), the spring (14) automatically returns said lever, in the coupling position of the member (15) with the impression (16), FIG. this position, where the parking brake is always actuated following the tensile force exerted on the cable (la) while maintaining in angular position the support (3) whose toothed sector (21) is in engagement with the pawl (22). ), it is quite possible to select and engage a speed (the first or the reverse for example), the disc being no longer coupled with the carriage, figure 6.
Pour désactiver le frein de stationnement, il suffit d'escamoter par tout moyen connu et approprié le cliquet (22) et libérer, par conséquent, le câble (19) qui n'est plus soumis à un effort de traction (figure 7).  To deactivate the parking brake, it is sufficient to retract by any known and appropriate means the pawl (22) and release, therefore, the cable (19) which is no longer subjected to a tensile force (Figure 7).
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle : The advantages stand out well from the description, in particular one underlines and recalls:
La double fonction exercée par le levier de manœuvre pour assurer, d'une part le passage et la sélection des vitesses et, d'autre part, actionner le frein de positionnement avec la possibilité d'utiliser un levier équipé d'une gâchette de verrouillage de la marche arrière. The double function exerted by the operating lever to ensure, on the one hand the passage and the selection of the speeds and, on the other hand, to actuate the positioning brake with the possibility to use a lever equipped with a reverse lock trigger.
La possibilité de passer une vitesse en position d' actionnement du frein de stationnement.  The possibility of passing a speed in the position of actuation of the parking brake.
L'ergonomie du mouvement exercé sur le levier pour assurer l'une et l'autre de ces fonctions  The ergonomics of the movement exerted on the lever to ensure one and the other of these functions
