La présente invention concerne un dispositif d'accouplement entre le rotor d'une machine électrique tournante réversible et l'arbre primaire de la boîte de vitesses d'un moteur thermique d'un groupe motopropulseur hybride d'un véhicule automobile. The present invention relates to a coupling device between the rotor of a reversible rotary electric machine and the primary shaft of the gearbox of a heat engine of a hybrid powertrain of a motor vehicle.
On connaît un tel dispositif selon lequel le rotor de la machine électrique est solidaire d'un moyeu monté concentriquement à l'arbre primaire de la boîte de vitesses et à rotation relativement à un carter fixe portant le stator de la machine électrique, le stator et le rotor étant coaxiaux et un entrefer étant défini entre la périphérie interne du stator et la périphérie externe du rotor. Such a device is known according to which the rotor of the electric machine is integral with a hub mounted concentrically to the primary shaft of the gearbox and rotated relative to a fixed casing carrying the stator of the electric machine, the stator and the rotor being coaxial and an air gap being defined between the inner periphery of the stator and the outer periphery of the rotor.
L'arbre primaire est monté à rotation à son extrémité située du côté de la boîte de vitessess par un palier à roulement baignant dans l'huile de boîte de vitessess et son extrémité opposée est également montée à rotation dans un trou borgne réalisé en bout de l'arbre vilebrequin du moteur thermique sans centrage. The primary shaft is rotatably mounted at its end located on the side of the vitessess box by a rolling bearing bathed in the gear box oil and its opposite end is also rotatably mounted in a blind hole made in the end. the crankshaft of the heat engine without centering.
L'arbre primaire est en outre accouplé à l'arbre vilebrequin par l'intermédiaire d'un embrayage pouvant être débrayé par une commande à butée de débrayage de manière à passer d'une position embrayée de l'embrayage dans laquelle la rotation de l'arbre vilebrequin est transmise à l'arbre primaire, à une position débrayée de cet embrayage, lors du passage d'un rapport de vitesse ou en mode électrique de fonctionnement du moteur, et à laquelle l'arbre vilebrequin est désaccouplé de l'arbre primaire. The primary shaft is further coupled to the crankshaft by means of a clutch which can be disengaged by a clutch release stop so as to move from an engaged position of the clutch in which the rotation of the clutch. crankshaft is transmitted to the primary shaft, to a disengaged position of this clutch, during the passage of a gear ratio or in electrical operating mode of the engine, and at which the crankshaft is uncoupled from the shaft primary.
Dans une telle architecture de groupe motopropulseur hybride avec ainsi la machine électrique tournante réversible située entre la boîte de vitessess et le moteur thermique, la commande de débrayage ne se trouve plus directement au contact de l'embrayage. Il y a donc un besoin de créer une liaison à travers la machine électrique. In such a hybrid powertrain architecture with the reversible rotary electric machine located between the gearbox and the engine, the clutch control is no longer directly in contact with the clutch. There is therefore a need to create a connection through the electric machine.
L'invention répond à ce besoin en proposant un dispositif d'accouplement entre le rotor d'une machine électrique tournante réversible et l'arbre primaire de la boîte de vitessess d'un moteur thermique d'un groupe motopropulseur hybride d'un véhicule automobile, le rotor étant solidaire d'un moyeu monté concentriquement à l'arbre primaire et à rotation relativement à un carter fixe portant un stator de la machine électrique définissant un entrefer avec le rotor, et l'arbre primaire pouvant être désacouplé en rotation de l'arbre vilebrequin du moteur par l'intermédiaire d'un embrayage débrayable par une commande à butée de débrayage, et qui est caractérisé en ce que la commande à butée de débrayage permet d'agir sur des extrémités d'au moins deux tiges cylindriques de poussée montées à coulissement parallèlement à l'arbre primaire au travers d'une paroi transversale à cet arbre d'une pièce accouplant le moyeu du rotor à l'arbre primaire, de manière à déplacer élastiquement un diaphragme d'embrayage, par l'intermédiaire d'une butée annulaire solidaire des extrémités des tiges de poussée opposées à leurs extrémités actionnées par la commande à butée de débrayage, pour amener ce diaphragme à sa position de débrayage de l'embrayage. The invention responds to this need by proposing a coupling device between the rotor of a reversible rotary electric machine and the primary shaft of the gearbox of a combustion engine of a hybrid powertrain of a motor vehicle. , the rotor being secured to a hub concentrically mounted to the primary shaft and rotated relative to a fixed housing carrying a stator of the electric machine defining an air gap with the rotor, and the primary shaft can be decoupled in rotation from the crankshaft of the engine via a clutch disengageable by a clutch release control, and which is characterized in that the clutch release control acts on ends of at least two cylindrical rods of thrust slidably mounted parallel to the primary shaft through a wall transverse to the one-piece shaft coupling the hub of the rotor to the primary shaft, so as to resiliently moving a clutch diaphragm, via an annular abutment integral with the ends of the thrust rods opposite their ends actuated by the clutch release control, to bring this diaphragm to its disengaged position of the clutch .
Les extrémités des tiges de poussée opposées à la butée de déplacement du diaphragme sont solidaires d'une plaque sensiblement circulaire perpendiculaire à l'arbre primaire et ayant un perçage central entourant coaxialement cet arbre, la butée de la commande de débrayage étant en appui sur la plaque circulaire. The ends of the thrust rods opposite to the displacement stop of the diaphragm are integral with a substantially circular plate perpendicular to the primary shaft and having a central bore coaxially surrounding this shaft, the abutment of the clutch control bearing against the circular plate.
De préférence, la commande à butée de débrayage agit sur trois tiges de poussée traversant respectivement trois perçages de la paroi transversale de la pièce d'accouplement et régulièrement espacés circonférentiellement les uns des autres de 120 d'angle. Preferably, the clutch release control acts on three thrust rods respectively passing through three holes in the transverse wall of the coupling piece and regularly spaced circumferentially from each other by 120 degrees.
La plaque circulaire est fixée aux extrémités des tiges de poussée par des vis de fixation et la butée de 2881494 3 déplacement du diaphragme est fixée aux extrémités opposées des tiges de poussée par des vis de fixation. The circular plate is attached to the ends of the push rods by fixing screws and the diaphragm stopper is attached to the opposite ends of the push rods by fixing screws.
La pièce d'accouplement comprend une couronne dentée extérieurement en engrènement à l'intérieur du moyeu du rotor et un manchon central monté directement sur l'arbre primaire en étant accouplé à ce dernier par une liaison à cannelures et la couronne dentée ainsi que le manchon central de la pièce d'accouplement ont leurs deux extrémités cylindriques qui sont opposées aux liaisons d'accouplement au moyeu du rotor et à l'arbre primaire, centrées respectivement dans le moyeu du rotor et sur l'arbre primaire suivant un ajustement lisse ou glissant. The coupling part comprises a ring gear externally meshing inside the rotor hub and a central sleeve mounted directly on the primary shaft being coupled thereto by a splined connection and the ring gear and the sleeve. central part of the coupling part have their two cylindrical ends which are opposed to the coupling connections to the rotor hub and to the primary shaft, respectively centered in the rotor hub and on the primary shaft in a smooth or sliding fit .
Les deux extrémités cylindriques de la couronne dentée et du manchon central de la pièce d'accouplement centrées dans le moyeu du rotor et sur l'arbre primaire sont situées d'un même côté parallèlement à l'arbre primaire. The two cylindrical ends of the ring gear and the central sleeve of the coupling piece centered in the rotor hub and on the primary shaft are located on the same side parallel to the primary shaft.
La pièce d'accouplement est immobilisée en translation relativement au moyeu du rotor et à l'arbre primaire d'une part par un épaulement réalisé dans la couronne dentée entre l'extrémité de la couronne dentée et les extrémités adjacentes des dents du moyeu du rotor de manière que les extrémités de ces dents soient en butée sur l'épaulement de la couronne et d'autre part par un épaulement de l'arbre primaire adjacent à ses cannelures de liaison avec le manchon central et sur lequel est en butée la cannelure du manchon central. The coupling piece is immobilized in translation relative to the hub of the rotor and the primary shaft on the one hand by a shoulder formed in the ring gear between the end of the ring gear and the adjacent ends of the teeth of the rotor hub. so that the ends of these teeth are abutting on the shoulder of the ring and secondly by a shoulder of the primary shaft adjacent to its connecting grooves with the central sleeve and on which is abutted the groove of the central sleeve.
La commande à butée de débrayage est du type hydraulique. The throttle stop control is of the hydraulic type.

La pièce d'accouplement 25 est immobilisée en translation relativement au manchon 7a du moyeu 7 du rotor 6 et à l'arbre primaire 8 d'une part par un épaulement 31 réalisé dans la couronne dentée 26 entre l'extrémité cylindrique 29 de la couronne 26 et les extrémités ajacentes des dents internes du manchon 7a du moyeu 7 de manière qu'en position montée de la pièce d'accouplement 25 dans le manchon 7a, les extrémités de ces dents viennent en appui sur l'épaulement 31 et d'autre part par un épaulement 32 de l'arbre primaire 8 adjacent à ses cannelures de liaison avec le manchon central 27 et sur lequel épaulement 32 est en appui un épaulement 33 du manchon central 27. The coupling piece 25 is immobilized in translation relative to the sleeve 7a of the hub 7 of the rotor 6 and to the primary shaft 8 on the one hand by a shoulder 31 made in the ring gear 26 between the cylindrical end 29 of the ring 26 and the ajacentes ends of the inner teeth of the sleeve 7a of the hub 7 so that in the mounted position of the coupling part 25 in the sleeve 7a, the ends of these teeth bear against the shoulder 31 and other part through a shoulder 32 of the primary shaft 8 adjacent its connecting grooves with the central sleeve 27 and on which shoulder 32 bears a shoulder 33 of the central sleeve 27.
2881494 7 Le montage s'opère comme suit: - l'arbre primaire 8 est monté dans la boîte de vitessess, - le manchon 25 est introduit sur l'arbre 5 primaire 8 jusqu'à l'appui sur l'épaulement 32, - puis le moyeu 7 de la machine électrique est introduit sur le manchon 25 jusqu'à l'appui sur l'épaulement 31. The assembly is carried out as follows: - the primary shaft 8 is mounted in the gearbox, - the sleeve 25 is inserted on the primary shaft 8 until it bears on the shoulder 32, - then the hub 7 of the electric machine is introduced on the sleeve 25 until it bears on the shoulder 31.
En prévoyant un ajustement glissant entre d'une part l'extrémité cylindrique 29 de la couronne 26 et le manchon 7a du moyeu 7 du rotor 6 et d'autre part l'extrémité cylindrique 30 et l'arbre primaire 8, on réalise une fonction de centrage de ces pièces séparée de la fonction de transmission de couple entre celles-ci, de sorte que les microdéplacements radiaux entre d'une part la couronne dentée 26 et le manchon 7a du moyeu 7 et d'autre part le manchon central 27 et l'arbre primaire 8, sont supprimés, ce qui par conséquent élimine les problèmes d'usure des dentures et des cannelures de ces pièces. By providing a sliding fit between firstly the cylindrical end 29 of the ring 26 and the sleeve 7a of the hub 7 of the rotor 6 and secondly the cylindrical end 30 and the primary shaft 8, a function is realized. of centering these parts separated from the torque transmission function between them, so that the radial microdisplacements between firstly the ring gear 26 and the sleeve 7a of the hub 7 and secondly the central sleeve 27 and the primary shaft 8, are removed, which therefore eliminates the problems of wear of the teeth and splines of these parts.
La commande à butée de débrayage 18, connue en soi, et par exemple du type hydraulique, est fixée dans le carter d'embrayage 2 côté boîte de vitessess, c'est-à-dire à l'opposé de l'embrayage, et est adaptée pour agir sur les extrémités d'au moins deux tiges cylindriques de poussée 34 montées à coulissement guidé parallèlement à l'arbre primaire 8 au travers d'une paroi 35 s'étendant transversalement à l'arbre primaire 8 et reliant la couronne dentée 26 au manchon central 27 de la pièce d'accouplement 25 qui est ainsi réalisée de façon monobloc. The control clutch release 18, known per se, and for example of the hydraulic type, is fixed in the clutch housing 2 side gear box, that is to say opposite the clutch, and is adapted to act on the ends of at least two cylindrical thrust rods 34 slidably mounted guided parallel to the primary shaft 8 through a wall 35 extending transversely to the primary shaft 8 and connecting the ring gear 26 to the central sleeve 27 of the coupling piece 25 which is thus made integrally.
De préférence, trois tiges coulissantes 34 sont prévues traversant à coulissement guidé respectivement trois perçages 36 de la paroi 35 régulièrement espacés circonférentiellement les uns des autres de 120 degrés d'angle. Preferably, three sliding rods 34 are provided through guided sliding respectively three holes 36 of the wall 35 regularly spaced circumferentially from each other by 120 degrees of angle.
2881494 8 Les tiges de poussée 34 comportent, à leurs extrémités opposées à celles sur lesquelles agit la commande à butée de débrayage 18, une butée annulaire 37 en appui au voisinage du bord délimitant le perçage central du diaphragme 21 disposé concentriquement autour du manchon central 27 de la pièce d'accouplement 25. La butée 37 est montée concentriquement à l'arbre primaire 8 et est en contact glissant sur le manchon central 27 qui assure ainsi le guidage en translation de la butée 37 lors de ses mouvements de débrayage et d'embrayage. The thrust rods 34 comprise, at their opposite ends to those on which the clutch abutment control 18 acts, an annular abutment 37 bearing in the vicinity of the edge delimiting the central bore of the diaphragm 21 arranged concentrically around the central sleeve 27. The stop 37 is mounted concentrically with the primary shaft 8 and is in sliding contact with the central sleeve 27 which thus ensures the translational guidance of the abutment 37 during its disengaging and disengaging movements. clutch.
La butée annulaire 37 est fixée aux extrémités correspondantes des tiges de poussée 34 par exemple par des vis de fixation 38 et une plaque circulaire 39 à perçage central 40 entourant concentriquement l'arbre primaire 8 est fixée aux extrémités opposées des tiges de poussée 34 par des vis de fixation 41. La plaque circulaire 39 s'étend perpendiculairement à l'axe longitudinal de l'arbre primaire 8. The annular abutment 37 is fixed to the corresponding ends of the thrust rods 34, for example by fastening screws 38, and a central drilling circular plate 39 concentrically surrounding the primary shaft 8 is fastened to the opposite ends of the thrust rods 34 by means of fixing screw 41. The circular plate 39 extends perpendicularly to the longitudinal axis of the primary shaft 8.
La demi-vue supérieure de la figure 2 montre que les tiges de poussée 34 et la butée annulaire 37 occupent une position embrayée du mécanisme d'embrayage tandis que la demi-vue inférieure de cette figure montre que la commande à butée de débrayage 18 a été pilotée de manière à déplacer en translation les tiges de poussée 34 et la butée annulaire 37 à une position débrayée du mécanisme d'embrayage. The upper half-view of FIG. 2 shows that the thrust rods 34 and the annular abutment 37 occupy an engaged position of the clutch mechanism while the lower half-view of this figure shows that the throttle stop control 18 has was controlled so as to move in translation the push rods 34 and the annular stop 37 to a disengaged position of the clutch mechanism.
Ainsi, la pièce d'accouplement 25 permet d'une part d'assurer la transmission de couple de la machine électrique 1 à l'arbre primaire 8 par des liaisons dentées et cannelées et d'autre part de guider les tiges de poussoir assurant la fonction d'embrayage et de débrayage du mécanisme d'embrayage par les deux butées situées aux extrémités de ces tiges. Thus, the coupling part 25 makes it possible, on the one hand, to ensure the transmission of torque from the electric machine 1 to the primary shaft 8 by toothed and fluted connections and, on the other hand, to guide the push rods providing the clutch mechanism and clutch release function by the two stops located at the ends of these rods.
