Abstract
Description
L'invention concerne un agencement de boîte de vitesses pour un véhicule à moteur comprenant une boîte de changement de vitesses, qui présente un appareil de commande. The invention relates to a gearbox arrangement for a motor vehicle comprising a gearbox, which has a control apparatus.
Alors que les boîtes de vitesses automatiques présentent un freinage de stationnement, qui doit empêcher un glissement du véhicule à l'arrêt, un système de ce type fait défaut dans le cas des boîtes de changement de vitesses automatisées, qui se composent en principe d'une boîte de changement de vitesses manuelle habituelle avec un système de réglage servant à sélectionner et à passer les vitesses, boîte de vitesse à laquelle est associé un appareil de commande. Le levier de sélection des vitesses est dans ce cas relié électriquement, par exemple au moyen d'un potentiomètre sur l'appareil de commande, à la boîte de vitesses de telle sorte que la boîte de vitesses puisse prendre les positions correspondant aux états de marche sélectionnés de cette façon, au moyen du levier de sélection, dont les positions correspondent aux positions habituelles dans le cas d'une boîte de vitesses automatique. While automatic gearboxes have parking brakes, which must prevent the vehicle from slipping when stationary, a system of this type is lacking in the case of automated gearboxes, which in principle consist of a conventional manual gearbox with an adjustment system for selecting and changing gears, a gearbox with which a control unit is associated. The gear selection lever is in this case electrically connected, for example by means of a potentiometer on the control unit, to the gearbox so that the gearbox can take the positions corresponding to the operating states selected in this way, using the selector lever, the positions of which correspond to the usual positions in the case of an automatic gearbox.
Alors qu'il manque ainsi aux boîtes de changement de vitesses automatisées connues, du type que l'on vient de décrire, un freinage de stationnement, l'invention a pour objet de compléter un agencement de boîte de vitesses en partant du fait que l'on doit pouvoir fournir avec une dépense additionnelle minimale aussi un freinage de stationnement. Celui-ci doit pouvoir être aussi utilisé dans le cas des boîtes de changement de vitesses normales. While there is thus a lack of known automatic gearboxes, of the type just described, parking braking, the object of the invention is to complete a gearbox arrangement starting from the fact that the '' we must be able to provide with a minimum additional expense also a parking brake. This must also be usable in the case of normal gearboxes.
La solution, conforme à l'invention, de ce problème consiste en ce que, pour obtenir un freinage de stationnement, l'appareil de commande se trouve en liaison opérationnelle avec un frein du véhicule, d'une manière telle que celui-ci ne soit activé par l'appareil de commande que dans le cas de positions de la boîte de vitesses qui requièrent un freinage de stationnement. The solution, in accordance with the invention, of this problem consists in that, in order to obtain parking braking, the control device is in operational connection with a brake of the vehicle, in such a way that the latter does not is activated by the control unit only in the case of gearbox positions which require parking braking.
Selon des dispositions préférées, éventuellement combinées
- le frein est un frein à main du véhicule,
- avec l'agencement à ressort vient en contact un levier pivotant, duquel part un organe de transmission de force allant au frein et avec lequel vient en contact un organe de réglage, qui peut être actionné par l'appareil de commande,
- l'organe de réglage est un vérin hydraulique à double effet, dont une partie constitutive est articulée sur le véhicule de façon solidaire et dont l'autre partie constitutive vient en contact avec le levier pivotant,
- l'appareil de commande est relié à un détecteur de contact d'allumage à serrure sur la serrure de contact du véhicule,
- la boîte de vitesses est une boîte de changement de vitesses à main ou une boîte de changement de vitesses automatisée,
- on relâche le freinage de stationnement lors du démarrage du moteur du véhicule et on le tire lors du débranchement du moteur du véhicule,
- le signal servant à faire démarrer ou à débrancher est signalé par un détecteur de la serrure de contact d'allumage,
- on retarde le relâchement du freinage de stationnement lors du démarrage du moteur, quand une position en pente du véhicule a été détectée.According to preferred arrangements, possibly combined
- the brake is a vehicle handbrake,
- with the spring arrangement, a pivoting lever comes into contact, from which a force transmission member going to the brake leaves and with which an adjustment member comes into contact, which can be actuated by the control device,
the adjusting member is a double-acting hydraulic cylinder, one component part of which is hinged to the vehicle in an integral manner and the other component part of which comes into contact with the pivoting lever,
- the control unit is connected to a lock ignition switch detector on the vehicle's contact lock,
- the gearbox is a manual gearbox or an automated gearbox,
- the parking brake is released when the vehicle engine is started and it is pulled when the vehicle engine is disconnected,
- the signal used to start or disconnect is signaled by a detector of the ignition switch,
- the parking brake release is delayed when the engine starts, when a sloping position of the vehicle has been detected.
On peut dire à la manière d'un slogan que, par les mesures selon l'invention, on fait du frein qui existe de toute façon, en particulier du frein à main du véhicule, à la fois un composant de l'agencement de boîte de vitesses constituant le freinage de stationnement. It can be said in the manner of a slogan that, by the measures according to the invention, the brake which exists anyway, in particular the vehicle hand brake, is both a component of the gearbox arrangement of speeds constituting the parking brake.
La configuration de l'invention, dans laquelle la liaison opérationnelle contient un agencement à ressort, qui est articulé de façon à pouvoir pivoter, avec deux positions de point mort (butées) autobloquantes, dont l'une est associée à l'état activé du frein et l'autre à son état désactivé, est particulièrement avantageuse, car un agencement à ressort assure avec des positions de point mort autobloquantes le fonctionnement du freinage de stationnement même quand la source d'énergie extérieure est en panne. Un apport d'énergie n'est ici nécessaire que quand l'agencement à ressort doit quitter sa position correspondante de point mort. The configuration of the invention, in which the operational link contains a spring arrangement, which is articulated so as to be able to pivot, with two self-locking neutral positions (stops), one of which is associated with the activated state of the brake and the other in its deactivated state, is particularly advantageous, because a spring arrangement ensures with self-locking neutral positions the operation of the parking brake even when the external power source is broken. An energy supply is only necessary here when the spring arrangement must leave its corresponding neutral position.
A ce sujet on doit ajouter que des freins à main pour des véhicules ou des remorques de véhicules avec des agencements à ressort mécaniques ou actionnés par un gaz comprimé, auxquels sont associés deux positions de point mort, font en soi partie de l'état de la technique; voir les documents DE 41 22 447 Al, EP 0 319 994 A2 ou DE-GM 88 05 106. A cet état de la technique il manque toutefois la caractéristique, essentielle selon l'invention, de l'utilisation d'un frein, existant de toute façon sur le véhicule, comme freinage de stationnement, pour une boîte de changement de vitesses à main ou pour une boîte de changement de vitesses automatisée. In this regard, it should be added that hand brakes for vehicles or vehicle trailers with mechanical spring arrangements or actuated by compressed gas, with which two neutral positions are associated, are in themselves part of the state of the technique; see documents DE 41 22 447 A1, EP 0 319 994 A2 or DE-GM 88 05 106. In this state of the art, however, the essential characteristic of the invention lacks the use of an existing brake in any case on the vehicle, as a parking brake, for a manual gearbox or for an automated gearbox.
On va décrire ci-après un exemple de réalisation de l'invention à partir du dessin schématique unique. An exemplary embodiment of the invention will be described below from the single schematic drawing.
On a désigné par la référence 1 l'appareil de commande connu en soi pour une boîte de changement de vitesses non représentée, car connue en soi. Entre ces deux systèmes il y a une liaison électrique de commande, qui donne l'assurance qu'au moyen d'un levier de sélection, également non représenté, associé à l'appareil de commande 1, la mise en place d'états de marche (positions du levier de sélection P, D, R, N) conduit à des mises en place correspondantes dans la boîte de changement de vitesses. The control device known per se has been designated by the reference 1 for a gear change box, not shown, since it is known per se. Between these two systems there is an electrical control link, which gives the assurance that by means of a selection lever, also not shown, associated with the control device 1, the establishment of on (positions of the selection lever P, D, R, N) leads to corresponding positioning in the gearbox.
Pour activer le freinage de stationnement l'appareil de commande est en outre relié à une serrure de contact de l'allumage 15, qui signale à l'appareil de commande l'actionnement d'une clé de contact.To activate the parking brake, the control device is also connected to an ignition ignition lock 15, which signals to the control device the actuation of an ignition key.
On a désigné par la référence 2 un frein de roue, connu également en soi, d'un véhicule à moteur, qui est en liaison opérationnelle, en étant constitué sous la forme d'un frein à main, par l'intermédiaire d'une timonerie de serrage de frein ou d'un câble de serrage de frein avec un levier de frein à main, qui se trouve à l'intérieur du véhicule et que l'on n'a pas non plus représenté. A wheel brake, also known per se, of a motor vehicle, which is in operational connection, being constituted in the form of a hand brake, by means of a brake linkage or a brake cable with a handbrake lever, which is inside the vehicle and which has not been shown either.
Ce qui est alors essentiel pour l'invention, c'est l'utilisation de ce frein de véhicule 2, qui existe de toute façon, en même temps comme freinage de stationnement pour la boîte de vitesses. Dans ce but l'appareil de commande actionne par l'intermédiaire de conduites hydrauliques 3 et 4 l'organe de réglage 5 en fonction de l'état de marche respectivement sélectionné, de telle sorte que se produise ou non, par l'intermédiaire de la liaison opérationnelle, désignée de façon générale par la référence 6, entre lui et le frein 2, un actionnement du frein. Dans cet exemple de réalisation l'organe de réglage 5 est un vérin hydraulique à double effet, dont le cylindre est articulé à poste fixe en 7, tandis que son piston vient en contact par l'intermédiaire de la tige de piston 8 avec le levier à deux bras 9. Dans cet exemple de réalisation, la tige du piston 8 vient en contact avec la branche supérieure du levier 9, tandis que sa branche inférieure est reliée au frein 2 au moyen de l'organe de transmission de force 10, qui peut être un câble (câble Bowden) ou une tige. What is then essential for the invention is the use of this vehicle brake 2, which exists anyway, at the same time as parking braking for the gearbox. For this purpose, the control device actuates, by means of hydraulic lines 3 and 4, the adjusting member 5 as a function of the operating state respectively selected, so that it occurs or not, via the operational link, generally designated by the reference 6, between it and the brake 2, an actuation of the brake. In this embodiment, the adjusting member 5 is a double-acting hydraulic cylinder, the cylinder of which is articulated at a fixed position at 7, while its piston comes into contact via the piston rod 8 with the lever. with two arms 9. In this exemplary embodiment, the piston rod 8 comes into contact with the upper branch of the lever 9, while its lower branch is connected to the brake 2 by means of the force transmission member 10, which can be a cable (Bowden cable) or a rod.
On a reproduit le levier de pivotement 9 dans la position déployée qu'il prend quand le véhicule est en marche; il prend appui sur la butée fixe 11. Par contre on a indiqué par des lignes en tirets la position du levier pivotant 9 et de l'organe de transmission de force 10 quand le frein 2 fonctionne comme freinage de stationnement. Dans ce cas le levier pivotant 9 prend appui par son bras supérieur sur la butée fixe 12. The pivot lever 9 has been reproduced in the deployed position which it takes when the vehicle is in motion; it is supported on the fixed stop 11. On the other hand, the position of the pivoting lever 9 and of the force transmission member 10 has been indicated by dashed lines when the brake 2 operates as parking braking. In this case the pivoting lever 9 is supported by its upper arm on the fixed stop 12.
Il est alors important d'avoir l'agencement à ressort 14, articulé en 13 de façon à pouvoir pivoter, avec deux positions de points morts autobloquantes. La position de point mort de l'agencement à ressort 14, qui est constitué ici par un agencement mécanique télescopique à ressort, est représentée, quand le freinage de stationnement est opérationnel, par une ligne en tirets, la position de point mort est représentée, quand le freinage de stationnement est desserré, en trait plein. It is then important to have the spring arrangement 14, articulated at 13 so as to be able to pivot, with two positions of self-locking dead centers. The neutral position of the spring arrangement 14, which is constituted here by a telescopic mechanical spring arrangement, is represented, when the parking brake is operational, by a dashed line, the neutral position is represented, when the parking brake is released, in solid lines.
Les parties 9 et 14 sont déplacées, à partir de leurs positions déployées en prolongeant l'organe de réglage 5, à partir de leurs positions indiquées par des lignes en tirets, en raccourcissant l'organe de réglage 5, et mises dans l'autre position de point mort respectivement. Les chambres partielles, qui se trouvent dans le cylindre de l'organe de réglage 5, des deux côtés du piston qui marche à cet endroit, sont alimentées en fluide sous pression à partir de l'appareil de commande 1 par l'intermédiaire des conduites hydrauliques 3 et 4. Parts 9 and 14 are moved, from their deployed positions by extending the adjustment member 5, from their positions indicated by dashed lines, by shortening the adjustment member 5, and placed in the other neutral position respectively. The partial chambers, which are located in the cylinder of the regulating member 5, on both sides of the piston which operates there, are supplied with pressurized fluid from the control device 1 via the pipes. hydraulics 3 and 4.
En raison des positions de point mort autobloquantes de l'agencement à ressort 14, d'éventuelles oscillations de la pression ou chutes de la pression, comme celles qui peuvent se produire par exemple lors d'un long arrêt du véhicule, ne peuvent pas affecter l'action du freinage de stationnement. Due to the self-locking neutral positions of the spring arrangement 14, any pressure oscillations or pressure drops, such as those which can occur for example during a long stop of the vehicle, cannot affect the action of the parking brake.
On réalise en conséquence avec l'invention un agencement de boîte de vitesses, dans lequel est intégré avec des mesures simples un freinage de stationnement en se reportant sur le frein du véhicule qui existe de toute façon. Dans ce cas il ne doit pas s'agir seulement obligatoirement du frein à main, on doit pouvoir aussi se reporter dans le cadre de l'invention sur le frein à pied. Consequently, with the invention, a gearbox arrangement is made, in which parking brakes are integrated with simple measures, referring to the brake of the vehicle which exists anyway. In this case, it must not be necessarily only the hand brake, it must also be possible to refer in the context of the invention to the foot brake.
On peut utiliser ce dispositif dans ce cas de façon avantageuse non seulement dans le cas de boîtes de changement de vitesses à main, automatisées, mais aussi dans le cas de boîtes de changement de vitesses normales. This device can be used in this case advantageously not only in the case of manual gearboxes, automated, but also in the case of normal gearboxes.
Dans ce dernier cas le conducteur, quand il ne veut pas avoir à tirer le frein à main lors de l'arrêt du véhicule, par exemple en pente, n'a plus besoin d'engager une vitesse pour bloquer le véhicule. Au contraire le dispositif selon l'invention a aussi ici pour rôle d'activer le freinage de stationnement, que l'on a présenté, par exemple en coupant le contact d'allumage du véhicule ou en retirant la clé de contact. Le freinage de stationnement sera par contre relâché en actionnant l'allumage du moteur, par exemple en tournant la clé de contact dans la serrure de contact de l'allumage 15. On peut dans ce cas retarder le relâchement du freinage de stationnement quand un détecteur a détecté une position du véhicule en pente et en a informé l'appareil de commande. In the latter case, the driver, when he does not want to have to pull the handbrake when stopping the vehicle, for example on a slope, no longer needs to engage a gear to block the vehicle. On the contrary, the device according to the invention also here has the role of activating the parking braking, which has been presented, for example by switching off the ignition ignition of the vehicle or by removing the ignition key. The parking brakes will however be released by activating the ignition of the engine, for example by turning the ignition key in the ignition ignition lock 15. In this case, the parking brakes can be released when a detector detected a position of the vehicle on a slope and informed the control unit thereof.
