Abstract

Torque-dependent disengaging device for a motor vehicle clutch (10) in which an electronic control (14) converts a control pulse coming from a torque sensor (18) and relays it to an automatic clutch unit (13). The automatic clutch unit (14) opens and closes the clutch (10) by way of a suitable clutch control element (17) as a function of the torque detected by the torque sensor (18). A bridging circuit (16) is assigned to the electronic control (14), by means of which circuit the automatic clutch unit (13) can be shut down and the engine (11) used as engine brake during overrun conditions. A signal transmitter (21) assigned to the accelerator pedal (15) can also relay a closing command to the automatic clutch unit (13).

Description

La présente invention concerne un dispositif d'embrayage pour véhicules à moteur, avec interruption automatique de la chaîne cinématique entre le moteur et la boite de vitesses lorsque le véhicule tend à entraîner le moteur. The present invention relates to a clutch device for motor vehicles, with automatic interruption of the kinematic chain between the engine and the gearbox when the vehicle tends to drive the engine.

En raison de la pénurie croissante d'énergie, notamment à cause de l'augmentation constante des prix du pétrole, l'industrie s'efforce de réduire touJours davantage la consommation de carburant. Pendant la conduite d'un véhicule, il arrive fréquemment que celui-ci soit entraîné par sa masse à une vitesse qui pourrait être supérieure à celle qui correspond au régime du moteur. Dans une telle situation, le véhicule est freiné par le moteur qu'il lui faut entraîner (frein moteur).Mis à part quelques cas peu nombreux de freinage au moteur intentionnel, par exemple lors d'une descente trop abrupte en montagne ou pour renforcer l'effet du freinage sur les roues lorsque le véhicule est un camion lourdement chargE, cette situation n'est pas voulue. I1 est donc incompatible avec une utilisation optimale du carburant de laisser le moteur en aspirer sans fournir d'énergie utile, simplement pour le transformer en gaz polluants rejetés dans l'atmosphère. Chaque fois qu'une telle situation se produit, elle présente donc le double inconvénient de gaspiller de l'énergie motrice et de polluer l'environnement sans contrepartie utile. Due to the increasing energy shortage, notably due to the constant rise in oil prices, the industry is striving to reduce fuel consumption still further. While driving a vehicle, it often happens that it is driven by its mass at a speed that could be higher than that which corresponds to the engine speed. In such a situation, the vehicle is braked by the engine which it must drive (engine brake). Apart from a few cases of intentional engine braking, for example during a too steep descent in the mountains or to reinforce the effect of braking on the wheels when the vehicle is a heavily loaded truck, this situation is not intended. It is therefore incompatible with optimal use of fuel to let the engine suck it up without providing useful energy, simply to transform it into polluting gases discharged into the atmosphere. Whenever such a situation occurs, it therefore has the double disadvantage of wasting motive energy and polluting the environment without useful consideration.

Pour éviter cet entraînement du moteur par le véhicule et la consommation inutile de carburant qui en résulte, il a déJà été proposé dans la demande de brevet allemand DE-OS 27 48 697 d'interrompre la chaîne cinématique entre la boite de vitesses et le moteur lorsque la vitesse de rotation de ce dernier diminue et d'arrêter ainsi le moteur. Dans les longues descentes, il peut toutefois se produire un certain retard lors de la remise en marche de celui-ci. To avoid this driving of the engine by the vehicle and the unnecessary fuel consumption which results therefrom, it has already been proposed in the German patent application DE-OS 27 48 697 to interrupt the kinematic chain between the gearbox and the engine when the speed of rotation of the latter decreases and thus stopping the engine. In long descents, however, there may be some delay when restarting it.

L'objet de la présente invention est donc de réaliser un dispositif qui permet d'éviter ou de diminuer la consommation inutile de carburant lorsque le véhicule tend à entraîner le moteur et qu'on ne désire pas utiliser 1' effet de freinage du moteur. The object of the present invention is therefore to provide a device which makes it possible to avoid or reduce unnecessary fuel consumption when the vehicle tends to drive the engine and that the braking effect of the engine is not desired.

A cet effet dans le dispositif d'embrayage selon l'invention l'interruption de la chaine cinématique a lieu en fonction du couple. To this end, in the clutch device according to the invention, the interruption of the kinematic chain takes place as a function of the torque.

Dans une forme d'exécution de l'invention, il est prévu d'associer au dispositif d'embrayage un. systômat d' actionnement automatique, lui-même associé à une commande de préférence électronique et reliée à un capteur de couple. On obtient ainsi un dispositif au moyen duquel la chaîne cinématique entre le moteur et la boite de vitesses est interrompue automatiquement et sans gêne pour le conducteur lorsque la vitesse du véhicule tend à entraîner le moteur et rétablie de même lorsque cette situation a cessé. In one embodiment of the invention, provision is made to associate one with the clutch device. automatic actuation system, itself associated with an electronic control preferably and connected to a torque sensor. A device is thus obtained by means of which the kinematic chain between the engine and the gearbox is interrupted automatically and without discomfort for the driver when the speed of the vehicle tends to drive the engine and is restored as well when this situation has ceased.

Cette interruption peut être réalisée de façon à faire tourner le moteur au ralenti, c'est-à-direà a'un régime économique, ou à l'arrêter complètement.This interruption can be carried out so as to make the engine idle, that is to say at an economical speed, or to stop it completely.

Dans une forme d'exécution plus élaborée de l'invention, le capteur de couple associé à la commande électronique est placé dans le dispositif d'embrayage, oû.il est avantageusement situé dans la chaîne cinématique. Dans une autre forme d'exécution, il est prévu d'associer au système d'actionnement automatique un organe de réglage pour actionner le dispositif d'embrayage, cet organe de réglage pouvant être mécanique. In a more elaborate embodiment of the invention, the torque sensor associated with the electronic control is placed in the clutch device, where it is advantageously located in the kinematic chain. In another embodiment, provision is made to associate with the automatic actuation system an adjustment member for actuating the clutch device, this adjustment member possibly being mechanical.

Selon une autre caractéristique de l'invention, il est prévu d'associer à la commande électronique un circuit qui rend inopérante l'action du système automatique. Ceci permet d'éviter l'interruption de la chaîne cinématique lorsque, dans une longue descente, par exemple, on veut utiliser l'effet de freinage du moteur comme moyen de décélération supplémentaire' et soulager ainsi les freins du véhicule. Le conducteur peut généralement prévoir ces longues descentes et préparer son véhicule en fonction des nécessités prévisibles de la conduite. According to another characteristic of the invention, provision is made to associate with the electronic control a circuit which renders the action of the automatic system inoperative. This makes it possible to avoid the interruption of the kinematic chain when, on a long descent, for example, one wants to use the braking effect of the engine as an additional deceleration means and thus relieve the brakes of the vehicle. The driver can generally plan these long descents and prepare his vehicle according to the foreseeable needs of driving.

Dans une autre forme d'exécution de l'invention, il est adjoint à la commande électronique un générateur de signaux pour mettre fin à l'interruption de la chaîne ci nématique et, dans une variante de réalisation, ce générateur de signaux est associé à la pédale d'accélérateur. In another embodiment of the invention, a signal generator is added to the electronic control to end the interruption of the nematic chain and, in an alternative embodiment, this signal generator is associated with the accelerator pedal.

De toute façon, l'invention sera bien comprise à 1' aide de la description qui suit, en référence au dessin schématique annexé, dont l'unique figure est un schémabloc représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif. In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, the only figure of which is a diagram showing, by way of nonlimiting example, an embodiment of this device.

Le dispositif d'embrayage 10 représenté dans l'unique figure est monté dans la chaîne cinématique entre le moteur Il et la boite de vitesses 12. La force motrice produite par le moteur est transmise par l'organe de sortie du mouvement 20 de la boite de vitesses 12 aux roues motrices (non représentées) du véhicule. Dans le dispositif d'embrayage 10, la chaîne cinématique peut être interrompue ou rétablie à tout moment, de façon connue en soi. The clutch device 10 shown in the single figure is mounted in the kinematic chain between the engine II and the gearbox 12. The driving force produced by the engine is transmitted by the movement output member 20 of the box of speeds 12 to the driving wheels (not shown) of the vehicle. In the clutch device 10, the kinematic chain can be interrupted or restored at any time, in a manner known per se.

A ce dispositif d'embrayage 10 est associé un système d'actionnement automatique S 1 qui, par l'intermédiaire d'un organe de réglage mécanique 17, peut, en modifiant la position des organes de débrayage du dispositif 10, amener celui-ci à l'état débrayé ou embrayé.Le système automatique d'actionnement 13 reçoit des impulsions de serrage et de desserrage du dispositif d'embrayage 10 d'une commande 14, de préférence électronique. Cette commande électronique 14 est reliée par une ligne électrique 22 à un capteur de couple 18, qui, dans la forme d'exécution représentée, est monté à l'intérieur du dispositif d'embrayage 10, dans la chaîne cinématique. Le courant nécessaire à la commande électronique 14 est fourni par l'installation électrique 19 du véhicule. With this clutch device 10 is associated an automatic actuation system S 1 which, by means of a mechanical adjustment member 17, can, by modifying the position of the clutch release members of the device 10, bring the latter in the disengaged or engaged state. The automatic actuation system 13 receives tightening and loosening pulses from the clutch device 10 of a control 14, preferably electronic. This electronic control 14 is connected by an electric line 22 to a torque sensor 18, which, in the embodiment shown, is mounted inside the clutch device 10, in the kinematic chain. The current necessary for the electronic control 14 is supplied by the electrical installation 19 of the vehicle.

Outre les impulsions de commande envoyées par le capteur de couple 18, la volonté du conducteur joue un rôle important pour une commande optimale du desserrage du dispositif d'embrayage 10. C'est ainsi que le conducteur peut, par l'intermédiaire d'un générateur de signaux 21, informer la commande électronique de son intention d' accélérer le véhicule. Ce générateur de signaux 21 peut êlié, par exemple, à la pédale d'accélérateur 15. L'impul sion envoyée par le générateur de signaux 21 est également transmise comme ordre de serrage au dispositif d'embrayage par le système automatique 13. In addition to the control pulses sent by the torque sensor 18, the will of the driver plays an important role for optimal control of the release of the clutch device 10. This is how the driver can, via a signal generator 21, inform the electronic control of its intention to accelerate the vehicle. This signal generator 21 can be linked, for example, to the accelerator pedal 15. The pulse sent by the signal generator 21 is also transmitted as a tightening order to the clutch device by the automatic system 13.

Si le conducteur peut, d'après le tracé de la route, prévoir qu'il devra utiliser le frein au moteur pour la prochaine partie du parcours pour soulager les freins du véhicule au cours d'une longue descente, par exemple, il peut, en agissant sur un circuit 16, rendre inopérante 1' action de la commande électronique 14 et éviter ainsi 1' intervention du système automatique 13 lorsqu'il passe constamment de la pédale de frein à celle de l'accélérateur. Lorsque le circuit 16 est sous tension, le système automatique 13 ne provoque pas le desserrage du dispositif d'embrayage 10 et le moteur Il peut servir de frein supplémentaire lorsque le véhicule tend à aller plus vite que lui.  If the driver can, according to the road layout, foresee that he will have to use the engine brake for the next part of the journey to relieve the vehicle brakes during a long descent, for example, he can, by acting on a circuit 16, rendering the action of the electronic control 14 inoperative and thus avoiding the intervention of the automatic system 13 when it constantly changes from the brake pedal to that of the accelerator. When the circuit 16 is energized, the automatic system 13 does not release the clutch device 10 and the engine It can serve as an additional brake when the vehicle tends to go faster than it.
