Abstract

L'invention concerne un ensemble d'embrayage à friction, qui est constitué d'un embrayage de séparation 1 ainsi que d'un embrayage de démarrage et de changement de vitesse 2. De tels systèmes sont utilisés pour, par l'intermédiaire d'un générateur de démarrage et de l'embrayage de séparation, mettre en marche le moteur à combustion interne, et couper le moteur à tous les états de marche ne nécessitant pas d'entraînement. L'embrayage de démarrage et de changement de vitesse 2 est réalisé sous la forme d'un embrayage à diaphragme en construction " tirée ", et l'embrayage de séparation 1 est actionné, à la suite de la course de débrayage normale, par l'accomplissement d'une course supplémentaire prédéterminée. L'actionnement des deux embrayages 1, 2 peut ainsi être effectué avec un seul système de débrayage conventionnel 5.The invention relates to a friction clutch assembly, which consists of a separating clutch 1 as well as a starting and shifting clutch 2. Such systems are used for, through Starting a generator and separating clutch, starting the internal combustion engine, and shutting off the engine in all operating states not requiring drive. The starting and shifting clutch 2 is designed as a diaphragm clutch in "pull-out" construction, and the separating clutch 1 is actuated, following the normal disengagement stroke, by the 'completion of a predetermined additional stroke. The actuation of the two clutches 1, 2 can thus be performed with a single conventional clutch system 5.

Description

I Ensemble d'embrayage à friction La présente invention concerne unI Friction clutch assembly The present invention relates to a

ensemble d'embrayage à friction constitué d'un embrayage de séparation entre le vilebrequin d'un moteur à combustion interne et une masse d'inertie montée rotative, et d'un embrayage de démarrage et de changement de vitesse entre la masse d'inertie et un arbre de boîte de vitesses, les deux embrayages étant  friction clutch assembly consisting of a separation clutch between the crankshaft of an internal combustion engine and a mass of inertia rotatably mounted, and of a starting clutch and of gear change between the mass of inertia and a gearbox shaft, the two clutches being

nique commun, l'embrayage de démarrage et de changement de vitesse étant actionnable dans une première plage de course de débrayage, et 0 l'embrayage de séparation étant actionnable dans une deuxième plage de course de débrayage, faisant suite à la première dans la course de débrayage. On connaît, par exemple, un tel ensemble d'embrayage à friction par la demande de brevet allemand DE-2 931 515. Dans cet ensemble connu d'embrayage à friction, on utilise un système de débrayage qui actionne successivement les deux embrayages. Pour cela, pour une part, on utilise un embrayage à diaphragme de type "poussé" avec des leviers de débrayage supplémentaires et, pour une autre part, le mouvement de débrayage est transmis par l'intermédiaire d'une tringle dans l'arbre creux de boîte de vitesses. Dans tous les cas, des mécanismes de leviers relativement complexes sont prévus, au moins pour la transmission du  common pic, the starting and shifting clutch being actuable in a first disengaging stroke range, and 0 the separation clutch being actuable in a second disengaging stroke range, following the first in the stroke clutch release. For example, such a friction clutch assembly is known from German patent application DE-2 931 515. In this known friction clutch assembly, a clutch system is used which successively actuates the two clutches. For this, on the one hand, a diaphragm clutch of the "pushed" type is used with additional release levers and, on the other hand, the release movement is transmitted via a rod in the hollow shaft. gearbox. In all cases, relatively complex lever mechanisms are provided, at least for the transmission of

Selon l'invention, ce but est atteint par le fait que: a) l'embrayage de démarrage et de changement de vitesse est réalisé sous la forme d'un embrayage à diaphragme en construction "tirée", avec une butée de mouvement de débrayage dirigée en éloignement du moteur à combustion interne, b) le ressort diaphragme de l'embrayage de démarrage et de changement de vitesse est disposé sur le c8té du plateau de pression associé qui est  According to the invention, this object is achieved by the fact that: a) the starting and shifting clutch is produced in the form of a diaphragm clutch in "pulled" construction, with a disengaging movement stop directed away from the internal combustion engine, b) the diaphragm spring of the starting and shifting clutch is arranged on the side of the associated pressure plate which is

En configurant l'embrayage de démarrage et de changement de vitesse en embrayage à diaphragme "tiré", on assure la présence de peu d'éléments constructifs, avec un faible encombrement. Dans le même temps, ce type d'embrayage est particulièrement peu susceptible d'usure au niveau des points d'application mutuels du ressort diaphragme et du  lower, on a constructive element secured to the casing and, via a smaller diameter, on, an application circle provided on the pressure plate and, c) during the loosening process, the diaphragm spring comes s '' apply, on the side opposite the pressure plate, once the idle stroke has been completed, approximately in the region of the application circle against a clutch ring assembly which - externally surrounding the pressure plate - acts on the clutch separation for loosening. By configuring the starting clutch and the gear change clutch with a "pulled" diaphragm clutch, it ensures the presence of few constructive elements, with a small footprint. At the same time, this type of clutch is particularly unlikely to wear at the mutual points of application of the diaphragm spring and the

In addition, extended application surfaces are present in both axial directions. Possible wear appearing on the

Selon une configuration supplémentaire de l'invention, il est avantageux que le plateau de pression de l'embrayage de séparation soit sollicité par l'intermédiaire d'une rondelle-ressort en direction du moteur à combustion interne et que des goujons de traction s'étendent du plateau de pression dans la bague de débrayage et soient munis d'éléments de réglage. On obtient ainsi, avec des éléments constructifs simples, une transmission directe de la force de débrayage du ressort diaphragme au plateau de pression de l'embrayage de séparation. Les éléments de réglage prévus sous la forme d'écrous sont aisément accessibles par le côté boîte de vitesses.  clutch. According to a further configuration of the invention, it is advantageous that the pressure plate of the separation clutch is biased by means of a spring washer in the direction of the internal combustion engine and that the traction studs are extend from the pressure plate in the clutch release ring and are fitted with adjustment elements. One thus obtains, with simple constructive elements, a direct transmission of the declutching force from the diaphragm spring to the pressure plate of the separation clutch. The adjustment elements provided in the form of nuts are easily accessible from the gearbox side.

L'ensemble d'embrayage à friction fonctionne comme suit Pour mettre en route le moteur à combustion interne, on n'a pas besoin de démarrer, car les aimants 15 et les bobines 16 servent de générateur de démarrage. Les deux embrayages 1 et 2 sont débrayés en déplaçant le système de débrayage dans le sens de la flèche F, le plateau de pression 20 de l'embrayage de démarrage et de changement de vitesse 2 étant tout d'abord desserré, puis, une fois accomplie la course X, le plateau- de pression 25 de l'embrayage de séparation 1 est déserré, par l'intermédiaire de la bague de débrayage 21 et des goujons de traction 22. A cet état, les différentes masses librement rotatives, qui sont montées  The friction clutch assembly operates as follows. To start the internal combustion engine, there is no need to start, since the magnets 15 and the coils 16 serve as a starting generator. The two clutches 1 and 2 are disengaged by moving the declutching system in the direction of arrow F, the pressure plate 20 of the starting and shifting clutch 2 being first released, then, once when race X has been completed, the pressure plate 25 of the separating clutch 1 is released, by means of the disengaging ring 21 and the traction studs 22. In this state, the various freely rotating masses, which are climbs

En outre, les embrayages de ce type sont très insensibles au régime de rotation et font appel à peu d'éléments individuels.

In addition, clutches of this type are very insensitive to the rotation speed and require few individual elements. The arrangement of the declutching ring 21 on the side of the declutching system opposite the internal combustion engine allows very easy adjustment of the stroke X by means of
