Description
1 MODULE HYDRAULIQUE DISPOSE ENTRE UN MOTEUR THERMIQUE ET UNE TRANSMISSION, COMPORTANT UN MOYEN D'ACCOUPLEMENT ET UNE MACHINE HYDRAULIQUE La présente invention concerne un module hydraulique prévu pour être disposé entre un moteur thermique et une transmission d'un véhicule automobile hybride, ainsi qu'un véhicule automobile hybride équipé d'un tel module. Les véhicules hybrides comportent généralement un moteur thermique alimenté par un carburant, formant une motorisation principale, et une deuxième motorisation reliée à une réserve d'énergie auxiliaire, qui peut fonctionner en moteur en consommant cette énergie, ou à l'inverse fonctionner en génératrice en produisant une énergie rechargeant cette réserve lors des freinages du véhicule. L'énergie auxiliaire peut être en particulier l'électricité ou une pression hydraulique. Un type de véhicule hybride connu, présenté notamment par le document US-A1-20120258838, comporte une machine électrique disposée entre l'embrayage monté en sortie du moteur thermique, et la transmission, qui est reliée à des batteries de stockage pour à partir d'une rotation de l'arbre d'entrée de cette transmission, récupérer une énergie électrique, ou délivrer un couple moteur sur cet arbre. Cependant les batteries électriques sont lourdes et encombrantes par rapport à la quantité d'énergie qu'elles peuvent stocker. De plus elles sont chères, et présentent par leurs matériaux un impact important sur l'environnement pour leur fabrication et leur recyclage. Un autre type de véhicule hybride connu, présenté notamment par le document FR-A1-2973302, comporte une transmission équipée d'un train planétaire comprenant une couronne reliée à un moteur thermique, un pignon planétaire relié à une pompe hydraulique, et un porte-satellites relié à un différentiel de sortie entraînant les roues motrices. La transmission comporte de plus une entrée liée à une machine hydraulique pouvant travailler en moteur ou en pompe, qui peut être reliée au 3033740 2 différentiel de sortie par deux rapports de démultiplication différents, commandés par un manchon de synchronisation. Toutefois ce véhicule nécessite une transmission spécifique dédiée pour cette application, qui ne peut pas être réutilisée sur d'autres types de 5 véhicules. Cette transmission fabriquée alors en petite série, coûte relativement cher. La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure. Elle propose à cet effet un module hydraulique intermédiaire prévu pour 10 être disposé entre un moteur thermique et une transmission d'un véhicule hybride hydraulique, pour relier un arbre d'entrée lié à ce moteur et un arbre de sortie lié à cette transmission, caractérisé en ce qu'il comporte dans un carter fermé un moyen d'accouplement commandé des arbres d'entrée et de sortie, et une machine hydraulique entraînée par l'arbre de sortie, pouvant 15 fonctionner en moteur et en frein, ce carter fermé comprenant de plus un réservoir de fluide à la pression atmosphérique d'alimentation de cette machine. Un avantage de ce module hydraulique est que l'on regroupe plusieurs fonctions dans le même carter fermé, notamment le réservoir à la pression 20 atmosphérique et le moyen d'accouplement, ce qui permet de réaliser en interne les différents canalisations reliant ses fonctions, en évitant des moyens extérieurs nécessitant des connexions, qui ajouteraient de la complexité et des coûts. De plus ce module s'interposant entre le moteur thermique et la 25 transmission sans modifier cette transmission, on ne change pas l'architecture du véhicule et on peut utiliser des boîtes de vitesses manuelles ou automatisées standards, ce qui permet de limiter les coûts. Le module hydraulique intermédiaire selon l'invention peut de plus comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être 30 combinées entre elles. En particulier, le moyen d'accouplement peut être un embrayage du type humide.The present invention relates to a hydraulic module intended to be arranged between a heat engine and a transmission of a hybrid motor vehicle, as well as a hydraulic module that can be arranged between a heat engine and a transmission of a hybrid motor vehicle, as well as a hydraulic module. a hybrid motor vehicle equipped with such a module. Hybrid vehicles generally comprise a heat engine powered by a fuel, forming a main engine, and a second engine connected to a reserve of auxiliary energy, which can operate as a motor by consuming this energy, or conversely operate as a generator. producing an energy recharging this reserve during the braking of the vehicle. The auxiliary energy can be in particular electricity or a hydraulic pressure. A known type of hybrid vehicle, presented in particular in the document US-A1-20120258838, comprises an electric machine arranged between the clutch mounted at the output of the heat engine, and the transmission, which is connected to storage batteries for starting from a rotation of the input shaft of this transmission, recover electrical energy, or deliver a motor torque on this shaft. However, electric batteries are heavy and cumbersome compared to the amount of energy they can store. In addition, they are expensive, and their materials have a significant impact on the environment for their manufacture and recycling. Another type of known hybrid vehicle, presented in particular in the document FR-A1-2973302, comprises a transmission equipped with a planetary gear comprising a ring gear connected to a heat engine, a sun gear connected to a hydraulic pump, and a carrier. satellites connected to an output differential driving the driving wheels. The transmission further includes an inlet connected to a hydraulic machine that can work in motor or pump, which can be connected to the output differential by two different gear ratios, controlled by a synchronization sleeve. However, this vehicle requires a specific dedicated transmission for this application, which can not be reused on other types of vehicles. This transmission then manufactured in small series, is relatively expensive. The present invention is intended to avoid these disadvantages of the prior art. It proposes for this purpose an intermediate hydraulic module intended to be arranged between a heat engine and a transmission of a hybrid hydraulic vehicle, for connecting an input shaft connected to this engine and an output shaft connected to this transmission, characterized in that it comprises, in a closed casing, a means of controlled coupling of the input and output shafts, and a hydraulic machine driven by the output shaft, operable in motor and brake, this closed casing comprising in addition a fluid reservoir at the atmospheric pressure supply of this machine. An advantage of this hydraulic module is that several functions are grouped together in the same closed casing, in particular the tank at the atmospheric pressure and the coupling means, which makes it possible to carry out internally the various ducts connecting its functions, avoiding external means requiring connections, which would add complexity and costs. Moreover, this module interposing between the heat engine and the transmission without modifying this transmission, the architecture of the vehicle is not changed and standard manual or automated gearboxes can be used, which makes it possible to limit costs. The intermediate hydraulic module according to the invention may further comprise one or more of the following features, which may be combined with one another. In particular, the coupling means may be a wet type clutch.
3033740 3 Dans ce cas, le module hydraulique comporte avantageusement à l'intérieur du carter fermé un dispositif de contrôle du moyen d'accouplement commandé. Avantageusement, le module hydraulique comporte à l'intérieur du 5 carter fermé une unité de filtration et de refroidissement du fluide, recevant une circulation d'un liquide de refroidissement venant de l'extérieur. Avantageusement, les arbres d'entrée et de sortie sont alignés axiale ment. Selon un mode de réalisation, l'axe de la machine hydraulique est 10 décalé latéralement par rapport à l'axe des arbres d'entrée et de sortie. Dans ce cas, avantageusement la machine hydraulique comporte un barillet recevant sur son contour extérieur un pignon mené qui est engrené sur un pignon menant lié à l'arbre de sortie. Selon un autre mode de réalisation, l'axe de la machine hydraulique est 15 aligné sur les arbres d'entrée et de sortie, le module hydraulique comportant un train planétaire comprenant un élément lié à l'arbre d'entrée, et un autre entraînant cette machine hydraulique. Dans ce cas, avantageusement le module hydraulique comporte un frein freinant un des éléments du train planétaire, pour réaliser le moyen 20 d'accouplement commandé. L'invention a aussi pour objet un véhicule automobile hybride utilisant une énergie hydraulique, comprenant un moteur thermique entraînant une transmission, ce véhicule comportant un module hydraulique comprenant l'une quelconque des caractéristiques précédentes, qui est disposé entre le 25 moteur thermique et la transmission. L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d'exemple, en référence aux dessins annexés dans lesquels : - la figure 1 est un schéma de principe du montage d'un module 30 hydraulique selon l'invention ; - la figure 2 est un schéma de principe du contenu de ce module hydraulique ; 3033740 4 - la figure 3 est un schéma d'une machine hydraulique d'un type connu ; - la figure 4 est un schéma d'une machine hydraulique adaptée pour un module hydraulique selon l'invention ; - la figure 5 est un schéma d'un module hydraulique selon l'invention 5 présentant une machine hydraulique déportée ; et - la figure 6 est un schéma d'un module hydraulique selon l'invention présentant une machine hydraulique concentrique. La figure 1 présente un module hydraulique fermé 4 recevant d'un côté la puissance de l'arbre 6 d'un moteur thermique 2, appelé par la suite arbre 10 d'entrée, pour la renvoyer vers l'arbre 8 d'une transmission 10 comprenant différents rapports, appelé par la suite arbre de sortie. Les deux arbres d'entrée 6 et de sortie 8 sont alignés suivant un même axe, ce qui permet de garder une configuration d'origine habituellement utilisée sur les véhicules automobiles.In this case, the hydraulic module advantageously comprises inside the closed housing a control device of the controlled coupling means. Advantageously, the hydraulic module comprises, inside the closed casing, a unit for filtering and cooling the fluid, receiving a circulation of a cooling liquid coming from the outside. Advantageously, the input and output shafts are aligned axially. According to one embodiment, the axis of the hydraulic machine is offset laterally with respect to the axis of the input and output shafts.

Le module hydraulique 4 comporte le moyen d'accouplement commandé généralement disposé à l'entrée de la transmission 10 pour la 20 séparer du moteur thermique 2, notamment un embrayage à sec pour une boîte de vitesses manuelle ou robotisée, un double embrayage pour une boîte de vitesses à doubles embrayages, ou un convertisseur de couple pour une boîte de vitesses automatique. La figure 2 présente le module hydraulique 4 comprenant un carter 25 fermé 12 recevant le mouvement de l'arbre d'entrée 6, qui entraîne successivement suivant un même axe un premier volant d'inertie 20, un système d'amortissement des vibrations en torsion 22, un embrayage 24, et un deuxième volant d'inertie 26. Le mouvement est transmis ensuite suivant le même axe à un arbre 30 interne 14, qui est prolongé par l'arbre de sortie 8 relié à la transmission. En variante l'arbre interne 14 peut être constitué directement par l'extrémité de l'arbre de sortie 8.The transmission 10 may be in particular a manual or robotically controlled gearbox, a continuously variable transmission, a dual-clutch transmission or an automatic transmission. The hydraulic module 4 comprises the controlled coupling means generally disposed at the input of the transmission 10 to separate it from the heat engine 2, in particular a dry clutch for a manual or robotic gearbox, a double clutch for a gearbox double clutch gearboxes, or a torque converter for an automatic gearbox. FIG. 2 shows the hydraulic module 4 comprising a closed casing 12 receiving the movement of the input shaft 6, which drives successively along a same axis a first flywheel 20, a torsional vibration damping system. 22, a clutch 24, and a second flywheel 26. The movement is then transmitted along the same axis to an internal shaft 14, which is extended by the output shaft 8 connected to the transmission. In a variant, the internal shaft 14 can be constituted directly by the end of the output shaft 8.
3033740 5 Le module hydraulique 4 comporte en option un entraînement d'accessoires du véhicule 28, en particulier un alternateur, qui est entraîné dans cet exemple par un couple de pignons 30 prenant le mouvement sur l'arbre interne 14.The hydraulic module 4 optionally comprises an accessory drive of the vehicle 28, in particular an alternator, which is driven in this example by a pair of gears 30 taking the movement on the internal shaft 14.
5 Un autre couple de pignons 32, 80 prenant le mouvement sur l'arbre interne 14, entraîne une machine hydraulique 34 qui peut fonctionner dans les deux sens de rotation, en délivrant un couple moteur sur cet arbre à partir d'une énergie hydraulique reçue d'un accumulateur haute pression 38, ou en appliquant un couple de freinage sur cet arbre avec un fonctionnement en 10 génératrice rechargeant cet accumulateur. Une vanne de sortie haute pression 36 disposée en sortie de la machine hydraulique 34 vers l'accumulateur haute pression 38, comporte une position de libre passage dans les deux sens pour un fonctionnement en moteur de la machine recevant le fluide de cet accumulateur, et une position 15 comprenant un clapet anti-retour permettant seulement la recharge de l'accumulateur haute pression en fluide venant de cette machine pour un fonctionnement en génératrice. Un deuxième accumulateur basse pression 40 disposé comme l'accumulateur haute pression 38 à l'extérieur du carter fermé 12, est relié à 20 la machine hydraulique 34 par une unité de filtration et de refroidissement 48, afin de faire travailler cette machine par un transfert de fluide entre ces deux accumulateurs. L'accumulateur basse pression 40 travaillant par exemple à une pression de l'ordre de 20bars, permet d'améliorer le rendement général, et 25 d'obtenir un fonctionnement silencieux en évitant un phénomène de cavitation, qui peut de plus entraîner des défaillances. Un élément de sécurité 42 disposé entre l'accumulateur haute pression 38 et accumulateur basse pression 40, limite l'écart de pression entre ces deux accumulateurs à un seuil maximum ce qui permet notamment de 30 maîtriser des dysfonctionnements. L'unité de filtration et de refroidissement 48 est alimentée par une pompe de relevage 44 puisant le fluide dans un réservoir interne à la 3033740 6 pression atmosphérique 46, pour recharger en fluide le circuit basse pression comprenant son accumulateur 40, en fonction des différentes pertes des composants. L'unité de filtration et de refroidissement 48 comporte une circulation de 5 liquide de refroidissement venant de l'extérieur, comprenant une entrée 50 et une sortie 52 du carter fermé 12. Le réservoir interne 46 recueille les pertes des différents composants, en particulier celles de la machine hydraulique 34, et fournit le fluide de lubrification des différents composants internes en fonctionnement, 10 notamment les engrenages des couples de pignons 30, 32, 80. On peut en particulier prévoir une lubrification directe des composants nécessitant un flux de fluide, comme les couples de pignons 30, 32, 80, en les disposant en-dessous des fuites de la machine hydraulique 34. La basse pression fournie par l'unité de filtration et de refroidissement 15 48, est suffisante pour être aussi délivrée à un système de contrôle de l'embrayage 54 qui pilote cet embrayage 24. Le système de contrôle de l'embrayage 54 peut être en particulier un vérin qui effectue le serrage de cet embrayage 24, le fluide en retour vidant ce vérin étant reconduit vers le réservoir interne 46.Another pair of pinions 32, 80 taking the movement on the internal shaft 14, drives a hydraulic machine 34 which can operate in both directions of rotation, by delivering a motor torque on this shaft from a hydraulic energy received of a high pressure accumulator 38, or by applying a braking torque on this shaft with a generator operation recharging the accumulator. A high pressure outlet valve 36 disposed at the outlet of the hydraulic machine 34 to the high pressure accumulator 38 has a free passage position in both directions for motor operation of the machine receiving the fluid of this accumulator, and a position 15 comprising a non-return valve allowing only the refilling of the high pressure fluid accumulator from this machine for generator operation. A second low pressure accumulator 40 arranged as the high pressure accumulator 38 outside the closed housing 12, is connected to the hydraulic machine 34 by a filtration and cooling unit 48, in order to operate this machine by a transfer. of fluid between these two accumulators. The low-pressure accumulator 40 operating for example at a pressure of the order of 20 bars, makes it possible to improve the overall efficiency, and to obtain a silent operation by avoiding a phenomenon of cavitation, which can further cause failures. A security element 42 disposed between the high-pressure accumulator 38 and the low-pressure accumulator 40 limits the pressure difference between these two accumulators to a maximum threshold, which makes it possible in particular to control malfunctions. The filtration and cooling unit 48 is fed by a lifting pump 44 drawing the fluid into an internal tank at atmospheric pressure 46, to reload the low pressure circuit comprising its accumulator 40 as a function of the different losses. components. The filtration and cooling unit 48 has a coolant circulation coming from the outside, comprising an inlet 50 and an outlet 52 of the closed housing 12. The internal reservoir 46 collects the losses of the various components, in particular those of the hydraulic machine 34, and provides the lubrication fluid of the various internal components in operation, in particular the gears of the gear pairs 30, 32, 80. In particular, it is possible to provide direct lubrication of the components requiring a flow of fluid, such as the pinion pairs 30, 32, 80, placing them below the leaks of the hydraulic machine 34. The low pressure supplied by the filtration and cooling unit 48 is sufficient to be also delivered to a control system. control of the clutch 54 which controls this clutch 24. The control system of the clutch 54 may be in particular a jack which performs the tightening of this clutch 54. clutch 24, the fluid returning emptying this jack being conveyed to the internal reservoir 46.
20 Avantageusement on prévoit un embrayage 24 du type humide qui est compact, et qui peut être ainsi directement lubrifié et refroidi par le fluide contenu dans le carter fermé 12. La basse pression peut aussi servir à commander une transmission 10 comprenant des changements de vitesse automatisés, en alimentant des 25 valves et des vérins de commande. On obtient un module hydraulique 4 comprenant un certain nombre de fonctions internes autonomes, qui nécessite en plus des liaisons mécaniques un minimum de connexions vers l'extérieur. On a notamment un branchement sur les deux réservoirs haute 38 et basse pression 40, un 30 branchement sur l'entrée 50 et la sortie 52 du liquide de refroidissement, ainsi que des connexions électriques pour commander les composants électriques internes comme des électrovannes.Advantageously, a wet-type clutch 24 is provided which is compact and can thus be directly lubricated and cooled by the fluid contained in the closed casing 12. The low pressure can also be used to control a transmission comprising automated gear changes. by feeding valves and control cylinders. A hydraulic module 4 is obtained comprising a certain number of autonomous internal functions, which in addition requires mechanical connections with a minimum of connections to the outside. In particular, there is a connection to the two high and low pressure tanks 40, a connection to the inlet 50 and the outlet 52 of the coolant, as well as electrical connections for controlling the internal electrical components such as solenoid valves.
3033740 7 La figure 3 présente une machine hydraulique 34 d'un type connu, comprenant un arbre d'entrée 90 maintenu par deux roulements 68 disposés axialement de chaque côté du carter 92 de manière à obtenir un espacement important. Le mécanisme intérieur de la machine hydraulique 34 comprenant 5 le barillet 60, ses pistons axiaux 62 et le plateau inclinable d'actionnement des pistons 64, est disposé axialement entre les deux roulements 68. Le plateau inclinable 64 comporte un centre d'inclinaison qui se trouve au point 0, disposé axialement dans une partie médiane de ce plateau. Cette inclinaison est réglée par deux vérins V agissant axialement, qui sont 10 disposés en deux points diamétralement opposés par rapport à l'axe. Le côté avant de l'arbre 90 passe après le roulement 68, par un joint d'étanchéité dynamique à lèvre 94 pour sortir du carter 92, son extrémité supportant un pignon 80 recevant le mouvement d'un arbre parallèle portant un pignon correspondant engrenant dessus.3 shows a hydraulic machine 34 of a known type, comprising an input shaft 90 held by two bearings 68 axially disposed on each side of the housing 92 so as to obtain a large spacing. The internal mechanism of the hydraulic machine 34 comprising the barrel 60, its axial pistons 62 and the tilting plate for actuating the pistons 64, is arranged axially between the two bearings 68. The tilting plate 64 comprises a center of inclination which located at the point 0, arranged axially in a median part of this plate. This inclination is regulated by two axially acting cylinders V which are arranged at two diametrically opposite points with respect to the axis. The forward side of the shaft 90 passes after the bearing 68, by a dynamic lip seal 94 to exit the casing 92, its end supporting a pinion 80 receiving the movement of a parallel shaft carrying a corresponding pinion meshing on .
15 On obtient une machine hydraulique 34 présentant un encombrement axial important, l'épaisseur de la paroi arrière du carter 92, des deux roulements 68, du joint d'étanchéité 94 et du pignon 80 venant s'ajouter à la longueur de son mécanisme intérieur. La figure 4 présente une machine hydraulique 34 comprenant un barillet 20 60 recevant sur son contour radialement extérieur deux roulements 68 disposés axialement aux extrémités de ce barillet, qui sont prévus pour être maintenus dans le carter du module hydraulique 4 tout en assurant une bonne stabilité au barillet. Un pignon 80 fixé sur le contour extérieur du barillet 60, axialement 25 entre les deux roulements 68, permet la transmission du mouvement vers un arbre parallèle portant un pignon complémentaire engrenant dessus. Le pignon 80 peut être rapporté sur le barillet 60, ou taillé directement dans la matière de ce barillet. Le plateau inclinable 64 comporte un centre d'inclinaison qui se trouve 30 au point 0, disposé axialement à l'extérieur de ce plateau vers l'arrière, dans le barillet 60. Cette inclinaison est réglée par un vérin V agissant radialement, à une certaine distance axiale du point 0 pour obtenir un effort d'inclinaison.A hydraulic machine 34 having a large axial space is obtained, the thickness of the rear wall of the casing 92, the two bearings 68, the seal 94 and the pinion 80 being added to the length of its internal mechanism. . FIG. 4 shows a hydraulic machine 34 comprising a barrel 20 receiving on its radially outer contour two bearings 68 arranged axially at the ends of this barrel, which are intended to be held in the casing of the hydraulic module 4 while ensuring good stability at barrel. A pinion 80 fixed on the outer contour of the barrel 60, axially between the two bearings 68, allows the transmission of the movement to a parallel shaft carrying a complementary pinion meshing thereon. The pinion 80 may be attached to the barrel 60, or cut directly into the material of this barrel. The tilting plate 64 has a center of inclination which is located at the point 0, arranged axially outside this plate rearwardly, in the barrel 60. This inclination is regulated by a cylinder V acting radially, at a certain axial distance from the point 0 to obtain a tilting force.
3033740 8 On notera que le vérin V disposé radialement sur le côté, n'ajoute pas de longueur axiale sur la machine hydraulique 34. On obtient pour cette version un ensemble compact axialement. La figure 5 présente un module hydraulique 4 comprenant le premier 5 volant d'inertie 20 se trouvant à l'extérieur du carter fermé 12. La machine hydraulique 34 réalisée suivant le modèle présenté figure 4, disposée parallèlement à l'arbre interne 14, comprend un barillet 60 guidé dans le carter fermé 12 par les deux roulements 68 entourant ce barillet. Le pignon mené 80 fixé directement autour du barillet 60 entre les deux 10 roulements 68, engrène avec le pignon menant 32 fixé sur l'arbre interne 14. Un bloc hydraulique de commande 58 est disposé vers l'extérieur du carter fermé 12 dans un secteur opposé à celui occupé par la machine hydraulique 34, afin de ne pas augmenter l'encombrement radial global du module hydraulique 4.It will be noted that the cylinder V arranged radially on the side does not add any axial length to the hydraulic machine 34. This version provides an axially compact assembly. FIG. 5 shows a hydraulic module 4 comprising the first flywheel 20 located outside the closed casing 12. The hydraulic machine 34 made according to the model shown in FIG. 4, arranged parallel to the internal shaft 14, comprises a cylinder 60 guided in the closed housing 12 by the two bearings 68 surrounding the cylinder. The driven pinion 80 fixed directly around the barrel 60 between the two bearings 68, meshes with the driving pinion 32 fixed on the internal shaft 14. A hydraulic control unit 58 is disposed towards the outside of the closed casing 12 in a sector opposite to that occupied by the hydraulic machine 34, in order not to increase the overall radial space requirement of the hydraulic module 4.
15 On obtient pour ce module hydraulique 4 comprenant la machine hydraulique 34 déportée, un ensemble qui peut être axialement court. La figure 6 présente un module hydraulique 4 comprenant deux volants d'inertie 20 recevant un système d'amortissement des vibrations 22 disposé entre eux, qui se trouvent à l'extérieur du carter fermé 12. La machine 20 hydraulique 34 est disposée suivant l'axe des arbres d'entrée 6 et de sortie 8 du module hydraulique 4. Le barillet de cette machine 60 est directement relié à l'arbre de sortie 8. L'entrée de la puissance venant du moteur thermique 2 se fait par l'arbre d'entrée creux de grand diamètre 6, qui entraîne la couronne 25 extérieure 70 d'un train planétaire comprenant un porte-satellites 72 relié directement au barillet 60 de la machine hydraulique 34. Le pignon solaire 74 du train planétaire est relié à une forme cylindrique concentrique, entourée par un frein à bande 76 qui peut assurer son freinage progressif. Le barillet 60 de la machine hydraulique 34 est guidé par les deux 30 roulements 68 l'entourant, qui sont répartis axialement à ses extrémités, le roulement du côté du moteur thermique 2 étant disposé à l'intérieur de l'arbre creux d'entrée de grand diamètre 6. La liaison avec le porte-satellites 72 3033740 9 formant le moyen d'entraînement en rotation du barillet 60, est fixée axialement sur ce barillet entre les deux roulements 68. Le plateau inclinable 64 de commande des pistons 62, est disposé aussi à l'intérieur de l'arbre d'entrée creux de grand diamètre 6.For this hydraulic module 4 comprising the remote hydraulic machine 34, an assembly which can be axially short is obtained. FIG. 6 shows a hydraulic module 4 comprising two flywheels 20 receiving a vibration damping system 22 arranged between them, which are outside the closed casing 12. The hydraulic machine 34 is arranged according to the invention. axis of the input shaft 6 and output 8 of the hydraulic module 4. The barrel of this machine 60 is directly connected to the output shaft 8. The input of the power from the engine 2 is made by the shaft large diameter hollow inlet 6, which drives the outer ring 70 of a planetary gear comprising a planet carrier 72 connected directly to the cylinder 60 of the hydraulic machine 34. The sun gear 74 of the sun gear is connected to a shape concentric cylindrical, surrounded by a brake band 76 which can ensure its progressive braking. The barrel 60 of the hydraulic machine 34 is guided by the two bearings 68 surrounding it, which are distributed axially at its ends, the bearing on the side of the heat engine 2 being disposed inside the hollow input shaft. of large diameter 6. The connection with the planet carrier 72 forming the means for rotating the barrel 60, is fixed axially on this cylinder between the two bearings 68. The tilting plate 64 for controlling the pistons 62, is also disposed within the large diameter hollow input shaft 6.
5 Le frein à bande 76 constitue un moyen d'accouplement entre l'arbre d'entrée 6 et l'arbre de sortie 8 du module hydraulique 4, par le freinage du pignon solaire 74 du train planétaire donnant un entraînement progressif du porte satellite 72 avec une réduction de la vitesse, qui entraîne alors directement le barillet de la machine hydraulique 60 relié à l'arbre de sortie.The belt brake 76 constitutes a coupling means between the input shaft 6 and the output shaft 8 of the hydraulic module 4, by the braking of the sun gear 74 of the sun gear train giving a progressive drive of the planet gear 72 with a reduction in speed, which then directly drives the cylinder of the hydraulic machine 60 connected to the output shaft.
10 On obtient pour ce module hydraulique 4 comprenant la machine hydraulique 34 coaxiale, un ensemble qui est plus long axialement que la version présentée figure 5, mais qui peut comporter des dimensions radiales réduites. On notera que ces deux versions de module hydraulique 4 comportent 15 un carter fermé 12 qui peut être globalement cylindrique, avec un contour extérieur sensiblement aligné sur celui du volant d'inertie d'entrée 20. On peut alors loger ce module hydraulique 4 entre le moteur thermique 2 et la transmission 10 en prenant la place dédiée habituellement à l'embrayage à sec des boîtes de vitesses manuelles, ou au convertisseur de couple des 20 transmissions automatiques. On notera aussi qu'en regroupant un grand nombre de fonctions hydrauliques dans le carter fermé 12, on diminue le nombre de canalisations extérieures nécessaires, notamment vers le réservoir de fluide à la pression atmosphérique 46 qui est interne.For this hydraulic module 4 comprising the coaxial hydraulic machine 34, there is obtained an assembly which is longer axially than the version shown in FIG. 5, but which may comprise reduced radial dimensions. It will be noted that these two versions of hydraulic module 4 comprise a closed casing 12 which may be generally cylindrical, with an outer contour substantially aligned with that of the input flywheel 20. This hydraulic module 4 can then be housed between the heat engine 2 and the transmission 10 taking the place usually dedicated to the dry clutch of the manual gearboxes, or to the torque converter of the 20 automatic transmissions. It will also be noted that by grouping a large number of hydraulic functions in the closed casing 12, the number of external ducts required is reduced, in particular towards the fluid reservoir at atmospheric pressure 46 which is internal.
25 Le véhicule hybride peut conserver un type de transmission 10 produit en grande série et de manière économique, en intercalant simplement le module hydraulique 4 entre cette transmission et le moteur thermique 2 pour réaliser l'hybridation.The hybrid vehicle can maintain a type of transmission produced massively and economically, simply by interposing the hydraulic module 4 between this transmission and the heat engine 2 to perform the hybridization.
