Description

La présente invention concerne un dispositif pour accoupler à volenté à un arbre moteur tant un arbre mené qu'une masse d'inertie, notamment pour véhicules automobiles, comportant un embrayage, dit embrayage principal, agissant entre l'arbre moteur et l'arbre mené et un embrayage, dit embrayage inertiel, agissant entre l'arbre moteur et la masse d'inertie, chacun des deux embrayages étant, l'un comme l'autre, du type ayant un couvercle, montable par fixation sur un volant, au moins un plateau monté solidaire en rotation et mobile axialement sur le couvercle et au moins un disque de friction adapté à être serré et desserré entre le plateau et le volant, des moyens de serrage et de desserrage du disque de friction s'appuyant sur le couvercle et coopérant avec la plateau, et une commande, associée auxdits moyens de serrage et de desserrage, permettant d'obtenir à volonté le serrage et le desserrage du disque de friction, dispositif dans lequel la masse d'inertie constitue le volant de l'embrayage inertiel.The present invention relates to a device for freely coupling to a drive shaft both a driven shaft and a mass of inertia, in particular for motor vehicles, comprising a clutch, called the main clutch, acting between the drive shaft and the driven shaft and a clutch, called an inertial clutch, acting between the drive shaft and the inertia mass, each of the two clutches being, one like the other, of the type having a cover, mountable by fixing on a flywheel, at least a plate mounted integral in rotation and axially movable on the cover and at least one friction disc adapted to be tightened and loosened between the plate and the flywheel, means for tightening and loosening the friction disc resting on the cover and cooperating with the plate, and a control, associated with said tightening and loosening means, making it possible to obtain at will the tightening and loosening of the friction disc, device in which the mass of inertia constitutes the flywheel of the e inertial clutch.

Un tel dispositif est décrit, par exemple, dans la demande de brevet FR-A 2 560 125.Such a device is described, for example, in patent application FR-A 2,560,125.

Dans ce sus mentionné document (figure 1), le volant 11 D de l'embrayage principal est solidaire de l'arbre moteur A, tandis que le disque de friction 14D est, après montage du couvercle 10D sur le volant 11 D, solidaire en rotation de l'arbre mené B, le disque de friction 14E étant fixé au couvercle 10D par des pattes élastiques 25.In this above mentioned document (Figure 1), the flywheel 11 D of the main clutch is secured to the drive shaft A, while the friction disc 14D is, after mounting the cover 10D on the flywheel 11 D, secured in rotation of the driven shaft B, the friction disc 14E being fixed to the cover 10D by elastic tabs 25.

Les deux embrayages D, E sont emboités concentriquement l'un à l'intérieur de l'autre, les zones de friction 15D et 15E des deux disques de friction 14D et 14E étant sensiblement coplanaires, et l'embrayage inertiel E peut être lancé à l'aide d'un petit moteur électrique M et d'une liaison à courroie.The two clutches D, E are concentrically fitted one inside the other, the friction zones 15D and 15E of the two friction discs 14D and 14E being substantially coplanar, and the inertial clutch E can be launched at using a small electric motor M and a belt connection.

En pratique, la courroie coopère avec une poulie solidaire de la masse d'inertie C et un roulement à contact oblique 27 est interposé radialement entre la masse d'inertie C et un manchon en deux parties solidaires en rotation de l'arbre moteur A, la bague externe du roulement 27 portant la masse C.In practice, the belt cooperates with a pulley integral with the mass of inertia C and an angular contact bearing 27 is interposed radially between the mass of inertia C and a sleeve in two parts integral in rotation with the motor shaft A, the outer ring of the bearing 27 carrying the mass C.

Bien que donnant satisfaction une telle disposition conduit à disposer la partie courante ou principale de la masse d'inertie en porte à faux, c'est-à-dire à écartement axial par rapport au roulement 27, ce qui a pour résultat de faire travailler celui-ci dans des conditions pas aussi souhaitables que désirées. En outre, ledit roulement 27 est disposé au voisinage du plateau de réaction de l'embrayage principal, qui peut atteindre des températures non négligeables notamment en régime sévère d'utilisation, et de ce fait est soumis à des contraintes thermiques élevées.Although satisfying such an arrangement results in having the main or main part of the inertia mass cantilevered, that is to say axially spaced from the bearing 27, which has the result of making work this under conditions not as desirable as desired. In addition, said bearing 27 is disposed in the vicinity of the reaction plate of the main clutch, which can reach non-negligible temperatures, in particular under severe conditions of use, and therefore is subject to high thermal stresses.

Dans le document GB-A 2 054 491 il est prévu une disposition avec un embrayage interposé entre le vilebrequin et le volant de l'embrayage principal. Ceci conduit à bouleverser la constitution de l'embrayage principal et inertiel.In document GB-A 2 054 491 there is provided an arrangement with a clutch interposed between the crankshaft and the flywheel of the main clutch. This leads to upsetting the constitution of the main and inertial clutch.

La présente invention a pour objet de pallier ces inconvénients et donc de créer un dispositif, pour accoupler à volonté à un arbre moteur tant à un arbre mené qu'une masse d'inertie, dans lequel le roulement associé à la masse d'inertie subit des contraintes mécaniques et themiques moindres, sans bouleverser la constitution de l'embrayage principal et de l'embrayage inertiel, tout en procurant d'autres avantages.The object of the present invention is to overcome these drawbacks and therefore to create a device, for coupling at will to a drive shaft both to a driven shaft and to a mass of inertia, in which the bearing associated with the mass of inertia is subjected less mechanical and thematic constraints, without upsetting the constitution of the main clutch and the inertial clutch, while providing other advantages.

L'invention propose à cet effet un dispositif du type sus indiqué, caractérisé en ce que la partie centrale et principale de la masse d'inertie est disposée axialement entre les deux couvercles d'embrayage, écartés axialement l'un par rapport à l'autre à cet effet, en ce que le roulement de support de la masse d'inertie est porté par un manchon solidaire du couvercle de l'embrayage principal et en ce que le disque de friction de l'embrayage inertiel est monté solidaire en rotation sur ledit manchon.The invention provides for this purpose a device of the type indicated above, characterized in that the central and main part of the inertia mass is disposed axially between the two clutch covers, axially spaced apart from the other for this purpose, in that the bearing for supporting the inertia mass is carried by a sleeve integral with the cover of the main clutch and in that the friction disc of the inertial clutch is mounted integral in rotation on said sleeve.

Grâce à la disposition selon la présente invention la masse d'inertie est disposée à l'aplomb du roulement ce qui ménage celui-ci et permet l'utilisation d'une plus grande gamme de roulement.Thanks to the arrangement according to the present invention, the mass of inertia is arranged directly above the bearing, which protects it and allows the use of a greater range of bearings.

De plus ce roulement, du fait de son éloignement du plateau de réaction de l'embrayage principal est sujet à des températures moins élevées.In addition, this bearing, due to its distance from the reaction plate of the main clutch, is subject to lower temperatures.

On appréciera outre la configuration standard des embrayages, que les couvercles, les plateaux, et les garnitures du disque de friction de l'embrayage principal et de l'embrayage inertiel peuvent avoir la même taille ce qui facilite la standardisation de la fabrication. En outre, le plateau de réaction de l'embrayage principal est simplifié.It will be appreciated in addition to the standard configuration of the clutches, that the covers, the plates, and the linings of the friction disc of the main clutch and of the inertial clutch can have the same size which facilitates the standardization of the manufacture. In addition, the main clutch reaction plate is simplified.

Suivant une autre caractéristique le manchon appartient à une pièce fixée au couvercle. Cette disposition permet d'avoir un couvercle identique pour l'embrayage principal et inertiel, leur différentiation ne s'effectuant que par la fixation de la pièce au couvercle de l'embrayage principal.According to another characteristic, the sleeve belongs to a part fixed to the cover. This arrangement makes it possible to have an identical cover for the main and inertial clutch, their differentiation being effected only by fixing the part to the cover of the main clutch.

Suivant une autre caractéristique l'extrémité libre du manchon est profilée pour réception et liaison en rotation avec le disque de friction de l'embrayage inertiel.According to another characteristic, the free end of the sleeve is profiled for reception and connection in rotation with the friction disc of the inertial clutch.

Cette disposition permet un montage coulissant aisé du disque de friction de l'embrayage inertiel tout en conservant des garnitures de friction de taille identique à celle du disque de friction de l'embrayage principal.This arrangement allows easy sliding mounting of the friction disc of the inertial clutch while retaining friction linings of size identical to that of the friction disc of the main clutch.

Suivant une autre caractéristique la masse d'inertie constitue la bague externe du roulement.According to another characteristic, the mass of inertia constitutes the outer ring of the bearing.

Cette disposition est favorable à une réduction du temps de montage du dispositif et diminue le nombre de composants de celui-ci.This arrangement is favorable to a reduction in the assembly time of the device and reduces the number of components thereof.

Suivant une autre caractéristique le volant de l'embrayage principal porte une zone de démarrage pour coopération avec un dispositif de démarrage.According to another characteristic, the flywheel of the main clutch carries a starting zone for cooperation with a starting device.

Cette réalisation est particulièrement avantageuse. En effet, lors d'une circulation dans les embouteillages, il peut se faire que la masse d'inertie n'ait pas une vitesse de rotation suffisante pour relancer le moteur.This achievement is particularly advantageous. Indeed, during traffic in traffic jams, it may happen that the mass of inertia does not have a sufficient speed of rotation to restart the engine.

Antérieurement, dans le document FR-A 2 560 125, dans une telle situation, il fallait réactiver la masse d'inertie à l'aide du moteur de relance et de la transmission à courroie. Ceci entraînait un temps de démarrage, par exemple, au feu rouge supérieur à celui des véhicules classiques. Grâce à la sus mentionnée disposition il devient possible de relancer directement le volant de l'embrayage principal et doncPreviously, in document FR-A 2 560 125, in such a situation, it was necessary to reactivate the inertia mass using the restart motor and the belt transmission. This resulted in a starting time, for example, at a red light greater than that of conventional vehicles. Thanks to the above mentioned provision it becomes possible to directly restart the flywheel of the main clutch and therefore

de provoquer un démarrage instantané du véhicule. On appréciera qu'il devient possible de supprimer le moteur de relance ainsi que les poulies et la courroie de transmission, ce qui permet de gagner axialement quelques centimètres et de diminuer la ralentissement de la masse d'inertie dû notamment à ladite courroie, ainsi que d'atténuer les bruits en régime normal de marche.cause an instant start of the vehicle. It will be appreciated that it becomes possible to eliminate the stimulus motor as well as the pulleys and the transmission belt, which makes it possible to gain a few centimeters axially and to reduce the slowing down of the mass of inertia due in particular to said belt, as well as reduce noise in normal running conditions.

Suivant une autre caractéristique la masse d'inertie porte une zone de démarrage propre à coopérer avec un dispositif de démarrage.According to another characteristic, the mass of inertia carries a starting zone capable of cooperating with a starting device.

Cette caractéristique est favorable à une augmentation de la taille radiale de la masse d'inertie, et donc a une diminution de l'encombrement axial de l'ensemble.This characteristic is favorable to an increase in the radial size of the mass of inertia, and therefore to a reduction in the axial size of the assembly.

Suivant une autre caractéristique la zone de démarrage consiste en une bague de démarrage propre à coopérer avec le pignon lanceur d'un démarreur.According to another characteristic, the starting zone consists of a starting ring capable of cooperating with the starter pinion of a starter.

Suivant une autre caractéristique la zone de démarrage consiste en un rotor d'une machine électrique porté par la masse d'inertie à sa périphérie externe.According to another characteristic, the starting zone consists of a rotor of an electric machine carried by the mass of inertia at its external periphery.

En regard dudit rotor le carter de la cloche d'embrayage porte un stator. Ainsi, en régime normal de marche le dispositif selon l'invention, suivant une autre caractéristique peut être utilisé comme alternateur.Opposite said rotor, the clutch bell housing has a stator. Thus, under normal operating conditions, the device according to the invention, according to another characteristic, can be used as an alternator.

Dans le mode de réalisation représenté aux figures 1 à 3 le dispositif pour accoupler à volonté à un arbre moteur A, tant un arbre mené B qu'une masse d'inertie C, notamment pour un véhicule automobile, comporte un embrayage D, dit embrayage principal, agissant entre l'arbre moteur A et l'arbre mené B et un embrayage E, dit embrayage inertiel, agissant entre l'arbre moteur A et la masse d'inertie C.In the embodiment shown in Figures 1 to 3 the device for coupling at will to a motor shaft A, both a driven shaft B and a mass of inertia C, in particular for a motor vehicle, comprises a clutch D, called a clutch main, acting between the driving shaft A and the driven shaft B and a clutch E, called inertial clutch, acting between the driving shaft A and the mass of inertia C.

Ici, l'arbre moteur A est le vilebrequin du moteur thermique du véhicule, tandis que l'arbre mené B est l'arbre d'entrée de la boîte de vitesses. Chacun des deux embrayages D, E étant, l'un comme l'autre, du type ayant un couvercle 10D, 10E, montable par fixation sur un volant 11 D, 11 E, ou plateau de réaction 11 D, 11 E, un plateau de pression 13D, 13E, monté solidaire en rotation et mobile axialement par rapport au couvercle 10D, 10E, un disque de friction 14D, 14E, ayant une zone annulaire bilatérale de friction 15D, 15E, adaptée à être serrée et desserrée entre le plateau 13D, 13E et le volant 11 D, 11 E, et des moyens de serrage et de desserrage du disque de friction 14D, 14E coopérant avec le plateau 13D, 13E.Here, the drive shaft A is the crankshaft of the thermal engine of the vehicle, while the driven shaft B is the input shaft of the gearbox. Each of the two clutches D, E being, one as the other, of the type having a cover 10D, 10E, mountable by fixing on a flywheel 11 D, 11 E, or reaction plate 11 D, 11 E, a plate pressure 13D, 13E, mounted integral in rotation and axially movable relative to the cover 10D, 10E, a friction disc 14D, 14E, having a bilateral annular friction zone 15D, 15E, adapted to be tightened and loosened between the plate 13D , 13E and the flywheel 11 D, 11 E, and means for tightening and loosening the friction disc 14D, 14E cooperating with the plate 13D, 13E.

Ainsi qu'on le sait, une commande est associée auxdits moyens de serrage et desserrage et permet d'obtenir à volonté le serrage et le desserrage du disque 14D, 14E.As is known, a command is associated with said tightening and loosening means and makes it possible to obtain at will the tightening and loosening of the disc 14D, 14E.

Dans l'exemple de réalisation représenté les moyens de serrage et de desserrage de l'embrayage principal D comportent un diaphragme 16D (figure 2) ayant une partie périphérique continue 18D, formant rondelle Belleville, douée de précontrainte élastique de serrage, et une pluralité de fentes radiales 19D qui définissent des doigts de desserrage 20D coopérant avec la commande.In the example of embodiment shown, the means for tightening and loosening the main clutch D comprise a diaphragm 16D (FIG. 2) having a continuous peripheral part 18D, forming a Belleville washer, endowed with elastic pre-stress for tightening, and a plurality of radial slots 19D which define release fingers 20D cooperating with the control.

Le volant 11 E de l'embrayage inertiel E est monté libre en rotation au moyen de roulements 27 sur l'arbre A, tandis que le disque 14E est fixé au couvercle 1 CD par des pattes 25 élastiques.The flywheel 11 E of the inertial clutch E is mounted to rotate freely by means of bearings 27 on the shaft A, while the disc 14E is fixed to the cover 1 CD by elastic tabs 25.

Les moyens de serrage et de desserrage de l'embrayage inertiel E comportent un faux diaphragme 16E (figure 3), dont la partie périphérique est interrompue par des fentes radiales 23E rendant la partie périphérique 18E du faux diaphragme quasi exempte de précontrainte élastique. Le faux diaphragme 16E comporte, comme le diaphragme 16D, des doigts 20E séparés par des fentes 19E; lesdites fentes 19E alternant avec les fentes radiales 23E.The means for tightening and loosening the inertial clutch E comprise a false diaphragm 16E (FIG. 3), the peripheral part of which is interrupted by radial slots 23E making the peripheral part 18E of the false diaphragm almost free from elastic preload. The false diaphragm 16E comprises, like the diaphragm 16D, fingers 20E separated by slots 19E; said slots 19E alternating with radial slots 23E.

Le diaphragme 16D est monté basculant sur le couvercle 10D à l'aide de colonnettes 21 D fixées à ce couvercle 10D et une butée de commande 17D agit sur l'extrémité des doigts 20D. Le faux diaphragme 16E est centré sur le couvercle 10E par des pions de centrage (non représentés) engagés dans la partie élargie des fentes 19E. Une butée de commande 17E agit également sur l'extrémité des doigts 20E du faux diaphragme. Les deux butées de commande 17E et 17D sont actionnées par une fourchette 22E, 22D à partir d'un petit moteur électrique ME, par l'intermédiaire d'une pignonnerie ou tout autre moyen approprié désigné par 24E. Par exemple, il peut s'agir d'une commande motorisée telle celle décrite dans la demande de brevet FR-A 2 564 999, avec ressort modérateur d'effort attelé à un bras double.The diaphragm 16D is pivotally mounted on the cover 10D by means of balusters 21 D fixed to this cover 10D and a control stop 17D acts on the end of the fingers 20D. The false diaphragm 16E is centered on the cover 10E by centering pins (not shown) engaged in the enlarged part of the slots 19E. A control stop 17E also acts on the end of the fingers 20E of the false diaphragm. The two control stops 17E and 17D are actuated by a fork 22E, 22D from a small electric motor ME, by means of a gear or any other suitable means designated by 24E. For example, it may be a motorized control such as that described in patent application FR-A 2,564,999, with force moderating spring coupled to a double arm.

Pour désengager l'embrayage principal D il faut agir en poussant par l'intermédiaire de la butée de commande 17D sur les extrémités des doigts 20D du diaphragme 16D, pour engager l'embrayage inertiel E il faut agir en traction sur les extrémités des doigts 20E du faux diaphragme.To disengage the main clutch D it is necessary to act by pushing via the control stop 17D on the ends of the fingers 20D of the diaphragm 16D, to engage the inertial clutch E it is necessary to act in traction on the ends of the fingers 20E of the false diaphragm.

Lorsque le butée 17D est déplacée vers la gauche, à la figure 1 et la butée 17E à droite, l'embrayage D est désengagé tandis que l'embrayage E est engagé, ceci correspond à une condition dans laquelle le moteur est relancé par la masse d'inertie C.When the stop 17D is moved to the left, in Figure 1 and the stop 17E to the right, the clutch D is disengaged while the clutch E is engaged, this corresponds to a condition in which the engine is restarted by the mass of inertia C.

Lorsque la butée 17D est à droite at la butée 17E est déplacée vers la gauche, l'embrayage D est engagé et l'embrayage E est désengagé. Ceci correspond à un régime de croisière et la masse d'inertie est mise hors jeu. Lorsque les butées 17D et 17E sont toutes les deux à droite les deux embrayages sont engagés.When the stop 17D is on the right and the stop 17E is moved to the left, the clutch D is engaged and the clutch E is disengaged. This corresponds to a cruising speed and the mass of inertia is put out of play. When the stops 17D and 17E are both on the right the two clutches are engaged.

A la figure 4, on voit un dispositif selon la présente invention et par simplicité les mêmes éléments qu'à la figure 1 auront les mêmes références augmentées d'un indice 100. Ainsi, on voit en 111 D le volant ou plateau de réaction de l'embrayage principal D, en 110D, 114D, 113D respectivement le couvercle, le disque de friction, le plateau de pression de l'embrayage principal D. Le volant 111 D est du type classique et porte une zone de démarrage 140D ou de lancement, consistant ici en une bague de démarrage, propre à coopérer avec un dispositif de démarrage 150, ici le pignon lanceur 151 D d'un démarreur 150. Celui-ci est porté par une entretoise 152D solidaire de la cloche d'embrayage 153D fixée au carter 154D de la boîte de vitesses, dont on voit en 155D l'arbre primaire ou arbre mené B, et en 157D le pignon conique du réducteur en prise avec l'arbre de sortie de la boîte de vitesses. Le plateau de réaction 111 D est fixé au vilebrequin de l'arbre moteur A. Comme à la figure 1 l'embrayage principal est du type poussé, c'est-à-dire que le diaphragme 116D, interposé axialement entre le couvercle 110D et le plateau de presssion 113D, s'appuie, en position embrayage D engagé, par la partie périphérique externe de sa rondelle Belleville 118D sur un cordon 158D du plateau de pression 113D et par la partie périphérique interne de sa rondelle Belleville 118D sur un appui 159D porté par le couvercle 110D, ici un embouti formé dans celui-ci. Ici, le diaphragme 116D est comme le diaphragme 16D monté basculant sur le couvercle 110D par l'intermédiaire de colonnettes, non visibles, identiques au colonnettes 21 D de la figure 1. Sur les extrémités des doigts 120D du diaphragme 116D agit en poussant une butée de débrayage 117D. Celle-ci comporte, de manière connue en soi, un élément d'attaque formé ici par la bague interne d'un roulement 160D, conformé à cet effet, attelé axialement à un élément de manoeuvre 161 D sur lequel agit une fourchette, dont on voit en 122'D l'axe d'articulation. Pour plus de clarté cette fourchette, analogue à celle de la figure 1, n'a pas été représentée. Il en est de même pour le moteur et la pignonnerie qui agit sur ladite fourchette; ce moteur et cette pignonnerie étant identiques au moteur ME et à la pignonnerie 24E de la figure 1. Le disque de friction 114D est monté coulissant sur des cannelures 162D de l'arbre primaire B en étant lié en rotation à celui-ci. Ce disque de friction 114D est rigide, en variante non représentée il pourrait comporter un dispositif d'amortissement à ressorts, et on voit en 115D ses garnitures de friction propres à être serrées entre le plateau 113D et le volant 111 D sous l'action du diaphragme 116D. La référence C représente la masse d'inertie formant le volant ou plateau de réaction 111 E de l'embrayage inertiel E. Les références 110E, 113E, 116E, et 114E indiquent respectivement le couvercle, le plateau de pression, le faux diaphragme et le disque de friction de l'embrayage inertiel E. Tout comme le diaphragme 116D, le faux diaphragme 116E est interposé axialement entre le couvercle 110E et le plateau de pression 113 E en étant centré sur le couvercle 110E par des pions de centrage non représentés. En pratique, cette réalisation avec faux diaphragme 116E permet d'avoir des plateaux de pression 113E et 113D identiques, ainsi que les couvercles 110D, 110E leur différentiation ne s'effectuant que par les pions de centrage et les colonnettes.In Figure 4, we see a device according to the present invention and for simplicity the same elements as in Figure 1 will have the same references increased by an index 100. Thus, we see in 111 D the steering wheel or reaction plate the main clutch D, in 110D, 114D, 113D respectively the cover, the friction disc, the pressure plate of the main clutch D. The flywheel 111 D is of the conventional type and carries a starting area 140D or launching , consisting here of a starting ring, suitable for cooperating with a starting device 150, here the starter pinion 151 D of a starter 150. This is carried by a spacer 152D secured to the clutch housing 153D fixed to the housing 154D of the gearbox, of which the primary shaft or driven shaft B is seen in 155D, and in 157D the bevel gear of the reduction gear engaged with the output shaft of the gearbox. The reaction plate 111 D is fixed to the crankshaft of the engine shaft A. As in FIG. 1, the main clutch is of the pushed type, that is to say that the diaphragm 116D, interposed axially between the cover 110D and the pressure plate 113D, is supported, in the clutch position D engaged, by the external peripheral part of its Belleville washer 118D on a cord 158D of the pressure plate 113D and by the internal peripheral part of its Belleville washer 118D on a support 159D carried by the cover 110D, here a stamp formed therein. Here, the diaphragm 116D is like the diaphragm 16D pivotally mounted on the cover 110D by means of balusters, not visible, identical to the balusters 21 D of FIG. 1. On the ends of the fingers 120D of the diaphragm 116D acts by pushing a stop clutch release 117D. This comprises, in a manner known per se, a driving element formed here by the inner ring of a bearing 160D, shaped for this purpose, axially coupled to an operating element 161 D on which a fork acts, of which sees in 122'D the axis of articulation. For clarity, this range, similar to that of FIG. 1, has not been shown. It is the same for the engine and the gear which acts on said fork; this motor and this pinion being identical to the motor ME and to the pinion 24E of FIG. 1. The friction disc 114D is slidably mounted on splines 162D of the primary shaft B while being linked in rotation to the latter. This friction disc 114D is rigid, in a variant not shown, it could include a spring damping device, and we see in 115D its own friction linings to be clamped between the plate 113D and the flywheel 111 D under the action of diaphragm 116D. The reference C represents the mass of inertia forming the flywheel or reaction plate 111 E of the inertial clutch E. The references 110E, 113E, 116E, and 114E respectively indicate the cover, the pressure plate, the false diaphragm and the inertial clutch friction disc E. Like the diaphragm 116D, the false diaphragm 116E is interposed axially between the cover 110E and the pressure plate 113 E while being centered on the cover 110E by centering pins not shown. In practice, this embodiment with false diaphragm 116E makes it possible to have identical pressure plates 113E and 113D, as well as the covers 110D, 110E, their differentiation being effected only by the centering pins and the balusters.

Selon l'invention la partie courante 170E de la masse d'inertie C est disposée axialement entre les deux couvercles d'embrayage 110D, 110E, écartés axialement l'un par rapport à l'autre à cet effet, et la masse d'inertie C est supportée par la bague extérieure d'un roulement 127 porté par un manchon 200 solidaire du couvercle 110D de l'embrayage principal D, le disque de friction 114E de l'embrayage inertiel E étant monté solidaire en rotation sur ledit manchon 200.According to the invention, the main part 170E of the mass of inertia C is disposed axially between the two clutch covers 110D, 110E, axially spaced apart from one another for this purpose, and the mass of inertia C is supported by the outer ring of a bearing 127 carried by a sleeve 200 integral with the cover 110D of the main clutch D, the friction disc 114E of the inertial clutch E being mounted integral in rotation on said sleeve 200.

En pratique la partie courante 170E, qui correspond à la partie principale, forme la partie centrale de ladite masse d'inertie E, et le roulement 127 est localisé entre le moteur et la boîte de vitesses.In practice, the main part 170E, which corresponds to the main part, forms the central part of said mass of inertia E, and the bearing 127 is located between the engine and the gearbox.

Ici, le manchon 200 appartient à une pièce 201 dotée d'un flasque 202, pourvu d'une portée de centrage 203 à sa périphérie interne, par lequel il est centré sur le pourtour interne de l'ouverture central 204 du couvercle. Par sa périphérie externe, le flasque 202 est fixé au couvercle 110D par soudage par points, cette fixation s'effectuant radialement au-delà de l'appui 159D à niveau avec la paroi latérale 205D du couvercle 110D.Here, the sleeve 200 belongs to a part 201 provided with a flange 202, provided with a centering surface 203 at its internal periphery, by which it is centered on the internal periphery of the central opening 204 of the cover. By its external periphery, the flange 202 is fixed to the cover 110D by spot welding, this fixing being effected radially beyond the support 159D at level with the side wall 205D of the cover 110D.

On notera qu'il est tiré parti du profil du couvercle 110D, en effet le flasque 202 n'est en contact qu'avec les zones non embouties de la paroi transversale extrême 210D du couvercle 110D dans laquelle est pratiqué l'embouti pour formation de l'appui 159D. Ce couvercle 110D avec une première série 300D de plages coplanaires pour la fixation au plateau de réaction 111 D, un deuxième série de plages coplanaires, pour l'attache de languettes tangentielles (non représentées) liant en rotation le plateau de pression 113D au couvercle 110D tout en lui autoriant une mobilité axiale par rapport à celui-ci, une troisième série de plages coplanaires prolongée vers le centre par la paroi transversale 210D du couvercle, étant du type de celui divulgué dans le brevet FR-A 1 529 779 déposé le 8 mai 1967 ne sera pas décrit plus en détail ici. A son extrémité libre 211, le manchon 200 est profilé pour réception et liaison en rotation avec le disque de friction 114E de l'embrayage inertiel E. En pratique, ce profil consiste en des cannelures 211' et le disque de friction 114E comporte un voile dentelé intérieurement, pour coopération avec les cannelures 211'. Au voisinage de l'extrémité, la plus proche du flasque 202, de la cannelure 211' est prévue une gorge pour réception d'un circlips 212, servant de butée à une rondelle d'appui 213 formant épaulement pour la bague interne du roulement 127 à deux rangées de billes; ledit roulement 127 étant par ailleurs, du côté du couvercle 110D, en appui contre un épaulement 214 que comporte la pièce 201 au voisinage de sa portée 203. La masse d'inertie C est en deux parties, fixées l'une à l'autre pour liaison avec la bague externe du roulement 127, et a en section une forme de T dont les aîles surplombent les couvercles 110E, 110D et augmentent la masse. La fixation des deux masses peut être réalisée, après montage du roulement 127, 1 ou analogue. En pratique l'alésage interne 128 de la partie centrale 170E de la masse d'inertie est pourvu d'un enlèvement de matière pour logement de la bague externe du roulement 127. Une butée ce commande 117E agit en tirant sur les extrémités des doigts 120E du faux diaphragme 116E. Comme la butée 117D la butée de commande 117E comporte un élément d'attaque formé ici par la bague externe d'un roulement, un élément de manoeuvre attelé audit élément d'attaque et soumis à l'action d'une fourchette de débrayage, dont on a représenté ici seulement, par simplicité, l'axe de rotation 122'E. La fourchette est commandée par un moteur doté d'une pignonnerie identiques au moteur ME et à la pignonnerie 24E de la figure 1. On notera que l'élément de manoeuvre de la butée 117E coulisse sur un manchon de l'élément de manoeuvre 161 D de la butée de commande 117D; les deux butées étant commandées l'une indépendamment de l'autre.It will be noted that advantage is taken of the profile of the cover 110D, in fact the flange 202 is only in contact with the non-stamped areas of the extreme transverse wall 210D of the cover 110D in which the stamped is made for the formation of 159D support. This cover 110D with a first series 300D of coplanar areas for fixing to the reaction plate 111 D, a second series of coplanar areas, for attaching tangential tabs (not shown) connecting in rotation the pressure plate 113D to the cover 110D while allowing it to move axially with respect thereto, a third series of coplanar areas extended towards the center by the transverse wall 210D of the cover, being of the type of that disclosed in patent FR-A 1,529,779 filed on 8 May 1967 will not be described in more detail here. At its free end 211, the sleeve 200 is profiled for reception and connection in rotation with the friction disc 114E of the inertial clutch E. In practice, this profile consists of splines 211 ′ and the friction disc 114E comprises a web internally serrated, for cooperation with the splines 211 '. In the vicinity of the end, closest to the flange 202, of the groove 211 ′, a groove is provided for receiving a circlip 212, serving as a stop for a support washer 213 forming a shoulder for the inner ring of the bearing 127 with two rows of balls; said bearing 127 being moreover, on the side of the cover 110D, in abutment against a shoulder 214 that comprises the part 201 in the vicinity of its bearing 203. The mass of inertia C is in two parts, fixed to one another for connection with the outer ring of the bearing 127, and has a T-shaped section, the elders of which overhang the covers 110E, 110D and increase the mass. The two masses can be fixed, after mounting the bearing 127, 1 or the like. In practice, the internal bore 128 of the central part 170E of the inertia mass is provided with a material removal for housing the external ring of the bearing 127. A stop this control 117E acts by pulling on the ends of the fingers 120E of the false diaphragm 116E. Like the stop 117D, the control stop 117E comprises an attack element formed here by the outer ring of a bearing, an operating element coupled to said attack element and subjected to the action of a clutch release fork, of which here only shown, for simplicity, the axis of rotation 122'E. The fork is controlled by a motor fitted with a pinion identical to the ME motor and to the pinion 24E of FIG. 1. It will be noted that the operating element of the stop 117E slides on a sleeve of the operating element 161 D of the control stop 117D; the two stops being controlled one independently of the other.

De manière connue en soi, cet élément de manoeuvre 161 D coulisse sur une trompette de débrayage portée par la cloche d'embrayage 153D.In a manner known per se, this maneuvering element 161 D slides on a declutching trumpet carried by the clutch housing 153D.

On notera que la butée 117D est logée dans l'alésage interne du manchon 200, que la bague externe du roulement de la butée 117E est radialement à niveau avec l'extrémité 211 du manchon 200. Ainsi on utilise au mieux la place disponible tout en ayant un roulement 127 et des roulements pour les butées 117D et 117E de petite taille. Ainsi le roulement 127 est globalement disposé axialement dans l'intervalle qui existe entre les deux roulements des butées 117D et 117E; cet intervalle s'agrandit lorsque l'on desserre le diaphragme 116D de l'embrayage principal D et/ou lorsque l'on serre le faux diaphragme 116E de l'embrayage inertiel E. On appréciera que le dispositif peut se loger aisément dans le même encombrement axial que celui de la figure 1 et être moins encombrant du fait de la suppression de la courroie de transmission et de la poulie de la figure 1.It will be noted that the stop 117D is housed in the internal bore of the sleeve 200, that the outer ring of the bearing of the stop 117E is radially level with the end 211 of the sleeve 200. Thus the best use is made of the space available while having a bearing 127 and bearings for the small stops 117D and 117E. Thus the bearing 127 is generally disposed axially in the interval which exists between the two bearings of the stops 117D and 117E; this interval increases when the diaphragm 116D of the main clutch D is released and / or when the false diaphragm 116E of the inertial clutch E is tightened. It will be appreciated that the device can be easily accommodated in the same axial dimensions than that of FIG. 1 and be less bulky due to the elimination of the transmission belt and of the pulley of FIG. 1.

Le dispositif fonctionne de la manière décrite ci-après.The device operates as described below.

En marche de croisière, les garnitures de friction 115D de l'embrayage principal D sont serrées entre le plateau de pression 113 D et le volant 111D sous l'action de serrage exercée par le diaphragme 116D, tandis que les garnitures de friction 115E du disque de friction 114E de l'embrayage inertiel E, du fait de l'absence de précontrainte du faux diaphragme 116E, ne sont pas serrées entre le plateau de pression 113E et la masse d'inertie C. Dans ces conditions, l'embrayage inertiel E est désengagé et l'embrayage principal D est engagé.When cruising, the friction linings 115D of the main clutch D are clamped between the pressure plate 113 D and the flywheel 111D under the tightening action exerted by the diaphragm 116D, while the friction linings 115E of the disc 114E of the inertial clutch E due to the absence of pretension of the false diaphragm 116E, are not clamped between the pressure plate 113E and the inertia mass C. Under these conditions, the inertial clutch E is disengaged and the main clutch D is engaged.

Pour changer de vitesse, il suffit d'agir sur les extrémités des doigts 120D du diaphragme 116D à l'aide de la butée 117D en poussant, c'est-à-dire dans le sens axial allant de la boîte de vitesses à l'arbre moteur A, pour désengager l'embrayage principal, tandis que l'embrayage inertiel reste en position désengagée.To change speed, it suffices to act on the ends of the fingers 120D of the diaphragm 116D using the stop 117D by pushing, that is to say in the axial direction going from the gearbox to the motor shaft A, to disengage the main clutch, while the inertial clutch remains in the disengaged position.

Lors d'un arrêt, par exemple au feu rouge, on desserre J'embrayage principal et l'on coupe le moteur, l'embrayage inertiel étant désengagé.During a stop, for example at a red light, the main clutch is released and the engine is shut down, the inertial clutch being disengaged.

Pour redémarrer, la masse d'inertie C étant rotative du fait de son entraînement en rotation auparavant entretenu par le roulement 127, on serre l'embrayage inertiel en agissant par traction sur les extrémités des doigts 120E du faux diaphragme 116E, à l'aide de la butée 117E, c'est-à-dire en agissant dans le sens axial allant de l'arbre moteur A à la boîte de vitesses. Lors de ce fonctionnement, la butée 117E s'éloigne de l'extrémité libre 211 du manchon 200 et le disque de friction 114 E est progressivement serré entre le plateau de pression 113E et la masse d'inertie C. Par sa périphérie interne et la liaison à cannelures, le disque de friction 114E entraîne en rotation le manchon 200 et, par l'intermédiaire de la pièce 201, le couvercle 110D et donc le volant 111 D de l'embrayage principal et l'arbre moteur A.To restart, the mass of inertia C being rotary due to its rotary drive previously maintained by the bearing 127, the inertial clutch is tightened by acting by pulling on the ends of the fingers 120E of the false diaphragm 116E, using of the stop 117E, that is to say by acting in the axial direction going from the motor shaft A to the gearbox. During this operation, the stop 117E moves away from the free end 211 of the sleeve 200 and the friction disc 114 E is progressively clamped between the pressure plate 113E and the mass of inertia C. By its internal periphery and the splined connection, the friction disc 114E rotates the sleeve 200 and, through the part 201, the cover 110D and therefore the flywheel 111 D of the main clutch and the motor shaft A.

Après un arrêt prolongé, notamment le matin au démarrage du véhicule, il suffit à l'aide du démarreur et plus particulièrement du lanceur 151 D, d'entraîner la baque de démarrage 140D du volant 111 D pour lancer le moteur. Il en est de même lorsque la vitesse de rotation de la masse d'inertie n'est pas suffisante pour relancer par elle-même l'embrayage principal D. En effet, dans ce cas on peut agir directement sur le moteur par le lanceur 151 D, la bague 140D et le volant 111 D ce qui provoque un démarrage instantané du véhicule.After a prolonged stop, in particular in the morning when the vehicle starts, it suffices with the aid of the starter and more particularly of the launcher 151 D, to drive the starter pack 140D of the flywheel 111 D to start the engine. It is the same when the speed of rotation of the mass of inertia is not sufficient to restart by itself the main clutch D. In fact, in this case one can act directly on the engine by the starter 151 D, the ring 140D and the steering wheel 111 D which causes an instantaneous start of the vehicle.

On notera que l'utilisation du démarreur pour relancer, par exemple au feu rouge, la masse d'inertie n'est pas courante du fait de la suppression de la courroie de la figure 1, l'expérience de conduite ayant permis de constater que pour la grande majorité des arrêts en ville, la masse d'inertie garde un régime suffisant pour la relance du moteur thermique.It will be noted that the use of the starter to restart, for example at a red light, the mass of inertia is not common due to the removal of the belt in FIG. 1, the driving experience having shown that for the vast majority of stops in town, the mass of inertia keeps a sufficient speed for the restart of the heat engine.

La figure 5 est une vue analogue à celle de la figure 4 et ne diffère de celle-ci que par la localisation du démarreur et la position de la zone de démarrage. Ici, la zone de démarrage 140E est portée par la masse d'inertie C ce qui permet par recul du démarreur une augmentation du diamètre de la masse d'inertie favorable à une réduction de l'encombrement axial de l'ensemble. Dans ce cas, pour redémarrer le moteur au feu rouge il suffit de serrer l'embrayage inertiel pour entraîner le couvercle 110D par l'intermédiaire du manchon 200 et provoquer la rotation du volant 111 D.Figure 5 is a view similar to that of Figure 4 and differs from it only by the location of the starter and the position of the starting area. Here, the starting area 140E is carried by the mass of inertia C which allows by retraction of the starter an increase in the diameter of the mass of inertia favorable to a reduction in the axial size of the assembly. In this case, to restart the engine at red light, simply tighten the inertial clutch to drive the cover 110D via the sleeve 200 and cause the flywheel 111 D.

A la figure 6 il est tiré un parti supplémentaire de la masse d'inertie.In FIG. 6, an additional advantage is taken of the mass of inertia.

Plus précisément la masse d'inertie C porte, à se périphérie externe, un rotor 300 disposé en regard d'un stator 301 porté par le carter de la cloche d'embrayage. Ici, le rotor 300 comporte un paquet de tôles magnétiques, par exemple en fer doux, et est pincé entre les deux parties que comporte la masse d'inertie en étant radialement dans l'alignement du roulement 127. Comme visible sur cette figure 6, la masse d'inertie C est pourvue à sa périphérie externe d'une gorge pour recevoir le paquet de tôles. Le stator 301 est doté comme le roter 300 d'un paquet de tôles magnétiques, par exemple en fer doux, ainsi que d'au moins deux bobinages imbriqués, l'un des bobinages étant du type inducteur, tandis que le ou les autres étant du type induit. Ici, le stator 301 est collé sur une protubérance de l'entretoise 152D.More specifically, the mass of inertia C carries, at its outer periphery, a rotor 300 disposed opposite a stator 301 carried by the housing of the clutch housing. Here, the rotor 300 comprises a packet of magnetic sheets, for example of soft iron, and is pinched between the two parts which the mass of inertia comprises while being radially in alignment with the bearing 127. As can be seen in this FIG. 6, the mass of inertia C is provided at its outer periphery with a groove for receiving the packet of sheets. The stator 301 is provided, like the roter 300, with a packet of magnetic sheets, for example of soft iron, as well as at least two nested windings, one of the windings being of the inductor type, while the other being of the induced type. Here, the stator 301 is glued to a protuberance of the spacer 152D.

On appréciera, du fait de la disposition du rotor 300 à la périphérie externe de la masse d'inertie C, que le poids de celle-ci est augmenté ce qui permet ainsi, à inertie égale, de réduire les aîles axiales de ladite masse C. Par simplicité ce rotor 300 sera assimilé à la zone de démarrage des précédentes réalisations car comme l'équipage bague de démarrage 140D-démarreur 150 il forme avec le stator 301 un équipage pour lancer le moteur thermique.It will be appreciated, due to the arrangement of the rotor 300 at the external periphery of the mass of inertia C, that the weight of the latter is increased, which allows thus, with equal inertia, reduce the axial ancestors of said mass C. For simplicity, this rotor 300 will be assimilated to the starting zone of the previous embodiments because, like the starting ring 140D-starter 150 crew, it forms with stator 301 a crew to start the heat engine.

En régime normal de marche, la masse d'inertie tourne et l'ensemble rotor-stator de la machine électrique fonctionne comme un alternateur, un dispositif électrique redresseur et un régulateur de tension étant, de manière connue en soi, disposés dans le circuit électrique entre la batterie et les bobinages du stator 301. Au feu rouge, on coupe l'alimentation d'essence du moteur thermique, l'allumage et l'alimentation des bobinages du stator, ce qui libère complètement la masse d'inertie et permet par l'intermédiaire de celle-ci et de l'embrayage inertiel, de relancer ultérieurement le moteur thermique.In normal operating conditions, the mass of inertia rotates and the rotor-stator assembly of the electric machine functions as an alternator, an electric rectifier device and a voltage regulator being, in a manner known per se, arranged in the electric circuit. between the battery and the stator windings 301. At the red light, the fuel supply to the heat engine is cut off, the ignition and supply to the stator windings are cut, which completely releases the inertia mass and allows through it and the inertial clutch, to restart the engine later.

Lorsque la vitesse de la masse d'inertie n'est pas suffisante, et lorsque le moteur thermique est chaud, on peut remettre en route celui-ci en transformant l'ensemble rotor-stator en un moteur électrique grâce à une électronique appropriée prévue à cet effet entre la batterie et les bobinages. Une remise en route instantanée du moteur thermique est ainsi possible.When the speed of the inertia mass is not sufficient, and when the heat engine is hot, it can be started again by transforming the rotor-stator assembly into an electric motor thanks to appropriate electronics provided for this effect between the battery and the windings. Instant restart of the engine is thus possible.

Dans le cas d'un démarrage avec un moteur froid, par exemple lorsque l'usager utilise son véhicule le matin, l'ensemble rotor-stator avec son circuit électronique d'alimentation lance la masse d'inertie ce qui, par actionnement de l'embrayage inertiel, permet de démarrer le moteur thermique.In the case of starting with a cold engine, for example when the user uses his vehicle in the morning, the rotor-stator assembly with its electronic supply circuit launches the mass of inertia which, by actuation of the inertial clutch, allows the engine to be started.

On appréciera donc que l'ensemble rotor-stator a une fonction d'alternateur en régime de marche normal, de moteur de relance lorsque le moteur thermique est chaud, de moteur de lancement lorsque ledit moteur thermique est froid.It will therefore be appreciated that the rotor-stator assembly has the function of an alternator under normal operating conditions, of a restart engine when the heat engine is hot, of a launch engine when said heat engine is cold.

Bien entendu, en surdimensionnant l'ensemble rotor-stator de manière appropriée, on peut obtenir un démarrage direct du moteur thermique, l'embrayage inertiel étant alors en position engagée.Of course, by appropriately oversizing the rotor-stator assembly, it is possible to obtain a direct start of the heat engine, the inertial clutch then being in the engaged position.

Ainsi qu'il ressort à l'évidence de la description, les couvercles 110D, 110E, les plateaux 113D, 113E, ainsi que les garnitures de friction 115D, 115E ont la même taille. En pratique, les couvercles 110D, 110E sont identiques, leur différentiation s'opérant au dernier moment par fixation de la pièce 201 sur le couvercle 110D. Il en est de même pour les plateaux de pression 113D, 113E et les garnitures de friction 115D, 115E. Toutes ces dispositions favorisent la standardisation des la fabrication.As is evident from the description, the covers 110D, 110E, the plates 113D, 113E, as well as the friction linings 115D, 115E are the same size. In practice, the covers 110D, 110E are identical, their differentiation taking place at the last moment by fixing the part 201 on the cover 110D. The same applies to the pressure plates 113D, 113E and the friction linings 115D, 115E. All these provisions promote the standardization of manufacturing.

Il ressort également à l'évidence de la description que le manchon 200 peut être d'un seul tenant avec le couvercle 110D de l'embrayage principal D. Il en est ainsi lorsque, par exemple, contrairement aux réalisations décrites ci-dessus où les couvercles sont réalisés en tôle emboutie, les couvercles sont réalisés par moulage, notamment en fonte. On appréciera également que la suppression de la courroie réduit la consommation d'énergie en régime normal de marche et améliore le confort en réduisant les bruits.It is also evident from the description that the sleeve 200 can be in one piece with the cover 110D of the main clutch D. This is so when, for example, unlike the embodiments described above where the covers are made of pressed sheet metal, the covers are made by molding, in particular cast iron. It will also be appreciated that the removal of the belt reduces energy consumption under normal running conditions and improves comfort by reducing noise.

Bien entendu, la présente invention n'est pas limitée aux exemples de réalisations décrits. En particulier selon les cas il est possible d'employer d'autres types de roulement, par exemple des roulements à aiguilles, au lieu du roulement 127 à deux rangées de billes sans contact oblique décrit ci-dessus. Le faux diaphragme de l'embrayage inertiel peut être remplacé par un vrai diaphragme. Dans ces conditions il suffit constamment d'agir en poussée sur le diaphragme de l'embrayage inertiel pour mettre hors service la masse d'inertie lorsque l'on n'a pas besoin de celle-ci.Of course, the present invention is not limited to the examples of embodiments described. In particular, depending on the case, it is possible to use other types of bearing, for example needle bearings, instead of the bearing 127 with two rows of balls without oblique contact described above. The false diaphragm of the inertial clutch can be replaced by a real diaphragm. Under these conditions, it suffices constantly to act on thrust on the diaphragm of the inertial clutch in order to deactivate the inertial mass when it is not needed.

On notera que dans ce cas là les deux butées de commande agissent en poussée sur les embrayages et que l'embrayage inertiel a une structure identique à celui de l'embrayage principal, en étant doté comme celui-ci de colonnettes pour montage pivotant du diaphragme de l'embrayage inertiel sur le couvercle de celui-ci. De plus, l'embrayage principal D pourrait être du type tiré, dans ce cas le diaphragme 116D s'appuierait par la partie périphérique externe de sa rondelle Belleville 118D sur le couvercle, et par la partie périphérique interne de sa partie rondelle Belleville 118D sur un cordon du plateau de pression 113D. Bien sûr, dans ce cas, la butée 117D agirait par traction sur les doigts 120D du diaphragme 116E. La commande de l'embrayage inertiel E étant indépendante de la commande de l'embrayage principal D, l'embrayage inertiel E pourrait avoir également une structure d'embrayage tiré pour conservation d'éléments standards. Dans ce cas, il faudrait agir en poussant sur les extrémités des doigts 120E du faux diaphragme pour serrer l'embrayage inertiel E.It will be noted that in this case the two control stops act in thrust on the clutches and that the inertial clutch has a structure identical to that of the main clutch, being provided like this with balusters for pivoting mounting of the diaphragm of the inertial clutch on the cover thereof. In addition, the main clutch D could be of the pulled type, in this case the diaphragm 116D would be supported by the external peripheral part of its Belleville washer 118D on the cover, and by the internal peripheral part of its Belleville washer part 118D on a pressure plate cord 113D. Of course, in this case, the stop 117D would act by traction on the fingers 120D of the diaphragm 116E. The control of the inertial clutch E being independent of the control of the main clutch D, the inertial clutch E could also have a clutch structure pulled for conservation of standard elements. In this case, it would be necessary to act by pushing on the ends of the fingers 120E of the false diaphragm to tighten the inertial clutch E.

En outre, au lieu de démarreur on peut utiliser un moteur de relance avec un pignon de forme conique adapté à coopérer avec und zone de démarrage complémentaire prévue à cet effet par exemple sur la masse d'inertie. La bague de démarrage peut être portée par la couvercle de l'embrayage inertiel et les moyens de serrage et de desserrage des embrayages inertiel et principal consistés en une pluralité de ressorts à boudin et de leviers. De même, à la figure 4 la position du démarreur 150 peut être inversée en sorte que sa partie courante est disposée au voisinage du moteur thermique ce qui permet d'augmenter le diamètre de la masse d'inertie et donc de réduire encore la dimension axiale de l'ensemble.In addition, instead of a starter, it is possible to use a recovery motor with a conical pinion adapted to cooperate with an additional starting zone provided for this purpose, for example on the mass of inertia. The starter ring can be carried by the cover of the inertial clutch and the means for tightening and loosening the inertial and main clutches consist of a plurality of coil springs and levers. Similarly, in Figure 4 the position of the starter 150 can be reversed so that its current part is arranged in the vicinity of the heat engine which allows to increase the diameter of the mass of inertia and therefore further reduce the axial dimension from the whole.

Enfin, la pièce 201 au lieu d'être fixée au couvercle 110D par soudage pourrait être rivetée sur le couvercle 110D. Par exemple, en alternance avec les colonnettes 21 D servant pour le basculement du diaphragme 116D, il pourrait être prévu des colonnettes dirigées en sens axial inverse à celui des colonnettes 21 D pour fixation de la pièce 201.Finally, the part 201 instead of being fixed to the cover 110D by welding could be riveted on the cover 110D. For example, alternating with the balusters 21 D serving for the tilting of the diaphragm 116D, it could be provided for balusters directed in the opposite axial direction to that of the balusters 21 D for fixing the part 201.
