Definitions

  • the present invention relates to the field of transmissions for motor vehicles. It relates in particular to a torque transmission device intended to be arranged in the drive train of a motor vehicle, between a heat engine and a gearbox.
  • the invention more specifically relates to a torque transmission device for a hybrid type of motor vehicle in which a rotating electrical machine is arranged in the traction chain.
  • transmission assemblies arranged between the gearbox and the engine and comprising a rotating electrical machine and a clutch on the motor side for coupling in rotation the crankshaft of the engine to the rotor of the rotating electric machine.
  • the rotating electrical machine can also constitute an electric brake or bring a surplus of energy to the engine to assist or prevent it from stalling.
  • the rotating electrical machine can also drive the vehicle. When the engine is running, the rotating electrical machine acts as an alternator.
  • Such a transmission assembly can also link the rotating electrical machine to the gearbox by two separate torque paths each comprising an output clutch and a gearbox input shaft.
  • the document DE102007003107 discloses a triple clutch in which the actuations are of the piston type with actuating chamber and balancing chamber.
  • a problem of this type of architecture lies in the complexity of mounting the transmission device. The invention thus aims to allow to benefit from a torque transmission device for a reliable and simplified mounting. The invention also aims to allow to benefit from a torque transmission device to reconcile the requirements of axial and radial compactness while having a long life and significant efficiency.
  • the rotating electrical machine and its components are particularly heavy and have an unbalance related to their manufacture and assembly, which is likely to increase the load on the support of the rotor.
  • acceleration of the vehicle can multiply by 10 or 20 the load on the rotor support. It is therefore also necessary to have a torque transmission device for supporting and rotating this rotating electrical machine and in particular the rotor.
  • the invention achieves this, in one of its aspects, by means of a torque transmission device, in particular for a motor vehicle, comprising:
  • a torque input element rotating about an axis X, able to be coupled in rotation to a crankshaft of a heat engine

  • a rotary electric machine comprising a rotor
  • an intermediate element defining a rotor support, said intermediate element and said rotor being arranged in the direction of the transmission of torque between the input element and the first output element and being selectively connected to the input element by an input clutch and the first output member by a first output clutch,

  • At least one rolling member arranged radially between the intermediate element and the protective casing
  • the radial succession is understood in terms of radial distance.
  • the input clutch, the actuating member associated with the input clutch and a rolling member radially follow one another towards the X axis.
  • the device has two bearing members arranged radially between the intermediate element and the protective casing.
  • the presence of these two bearings makes it possible to obtain improved guidance of the electric motor by the protective casing.
  • these rolling members are arranged on the same radial height.

  • the at least one rolling member is a bearing with a row of balls.
  • the intermediate element is carried by the protective casing only via at least one rolling member.
  • This has the advantage of reducing the number of intermediate piece between the rotor and the part carrying the rotor, in this case the protective housing. Indeed, too many intermediate parts leads to an increase in the side chain that results in an increase in the gap between the stator and the rotor and therefore a decrease in efficiency via a drop in the magnetic field.

Description

Dispositif de transmission pour véhicule hybride  Transmission device for a hybrid vehicle
La présente invention se rapporte au domaine des transmissions pour véhicules automobiles. Elle se rapporte notamment à un dispositif de transmission de couple destiné à être disposé dans la chaîne de traction d’un véhicule automobile, entre un moteur thermique et une boîte de vitesses. The present invention relates to the field of transmissions for motor vehicles. It relates in particular to a torque transmission device intended to be arranged in the drive train of a motor vehicle, between a heat engine and a gearbox.
L’invention concerne plus précisément un dispositif de transmission de couple pour un véhicule automobile de type hybride dans lequel une machine électrique tournante est disposée dans la chaîne de traction.  The invention more specifically relates to a torque transmission device for a hybrid type of motor vehicle in which a rotating electrical machine is arranged in the traction chain.
Dans l’état de la technique, il est connu des ensembles de transmission, disposés entre la boîte de vitesses et le moteur thermique et comportant une machine électrique tournante et un embrayage côté moteur permettant d’accoupler en rotation le vilebrequin du moteur thermique au rotor de la machine électrique tournante. Ainsi, il est possible de couper le moteur thermique à chaque arrêt du véhicule et de le redémarrer grâce à la machine électrique tournante. La machine électrique tournante peut également constituer un frein électrique ou apporter un surplus d’énergie au moteur thermique pour l’assister ou éviter que celui-ci ne cale. La machine électrique tournante peut également assurer l’entraînement du véhicule. Lorsque le moteur tourne, la machine électrique tournante joue le rôle d’un alternateur. Un tel ensemble de transmission peut également lier la machine électrique tournante à la boite de vitesses par deux chemins de couples distincts comprenant chacun un embrayage de sortie et un arbre d’entrée de boite de vitesses.  In the state of the art, it is known transmission assemblies, arranged between the gearbox and the engine and comprising a rotating electrical machine and a clutch on the motor side for coupling in rotation the crankshaft of the engine to the rotor of the rotating electric machine. Thus, it is possible to shut off the engine at each stop of the vehicle and restart it with the rotating electric machine. The rotating electrical machine can also constitute an electric brake or bring a surplus of energy to the engine to assist or prevent it from stalling. The rotating electrical machine can also drive the vehicle. When the engine is running, the rotating electrical machine acts as an alternator. Such a transmission assembly can also link the rotating electrical machine to the gearbox by two separate torque paths each comprising an output clutch and a gearbox input shaft.
Il existe des dispositifs comprenant trois organes d’actionnement distincts pour l’actionnement des trois embrayages, un embrayage d’entrée entre le moteur thermique et la machine électrique tournante et deux embrayages de sortie entre la machine électrique tournante et les deux arbres d’entrée d’une boite de vitesses. Dans ces dispositifs, la machine électrique tournante comprend un stator et un rotor entraîné en rotation autour d’un axe de rotation. Le document DE102007003107 divulgue un triple embrayage dans lequel les actionnements sont du type piston avec chambre d’actionnement et chambre d’équilibrage. Un problème de ce type d’architecture se trouve dans la complexité du montage du dispositif de transmission. L’invention vise ainsi à permettre de bénéficier d’un dispositif de transmission de couple permettant un montage fiable et simplifié. L’invention vise également à permettre de bénéficier d’un dispositif de transmission de couple permettant de concilier les exigences de compacité axiale et radiale tout en possédant une durée de vie et une efficacité importante. There are devices comprising three separate actuating members for actuating the three clutches, an input clutch between the thermal engine and the rotating electrical machine and two output clutches between the rotating electrical machine and the two input shafts. a gearbox. In these devices, the rotating electrical machine comprises a stator and a rotor driven in rotation about an axis of rotation. The document DE102007003107 discloses a triple clutch in which the actuations are of the piston type with actuating chamber and balancing chamber. A problem of this type of architecture lies in the complexity of mounting the transmission device. The invention thus aims to allow to benefit from a torque transmission device for a reliable and simplified mounting. The invention also aims to allow to benefit from a torque transmission device to reconcile the requirements of axial and radial compactness while having a long life and significant efficiency.
La machine électrique tournante et ses composants (rotor, stator, capteur(s),...) sont particulièrement lourds et comportent un balourd lié à leur fabrication et à leur assemblage, ce qui est susceptible d’augmenter la charge sur le support du rotor. De plus, une accélération du véhicule peut multiplier par 10 ou 20 la charge sur le support du rotor. Il est donc également nécessaire de disposer d’un dispositif de transmission de couple permettant de supporter et guider en rotation cette machine électrique tournante et notamment le rotor.  The rotating electrical machine and its components (rotor, stator, sensor (s), ...) are particularly heavy and have an unbalance related to their manufacture and assembly, which is likely to increase the load on the support of the rotor. In addition, acceleration of the vehicle can multiply by 10 or 20 the load on the rotor support. It is therefore also necessary to have a torque transmission device for supporting and rotating this rotating electrical machine and in particular the rotor.
L’invention y parvient, selon l’un de ses aspects, grâce à un dispositif de transmission de couple, notamment pour véhicule automobile, comprenant :  The invention achieves this, in one of its aspects, by means of a torque transmission device, in particular for a motor vehicle, comprising:
- un élément d’entrée de couple en rotation autour d’un axe X, apte à être couplé en rotation à un vilebrequin d’un moteur thermique,  a torque input element rotating about an axis X, able to be coupled in rotation to a crankshaft of a heat engine,
- un premier élément de sortie de couple, apte à être couplé en rotation à un premier arbre d’entrée d’une boite de vitesses,  a first torque output element adapted to be coupled in rotation to a first input shaft of a gearbox,
- une machine électrique tournante comprenant un rotor,  a rotary electric machine comprising a rotor,
- un élément intermédiaire définissant un support de rotor, ledit élément intermédiaire et ledit rotor étant disposés au sens de la transmission de couple entre l’élément d’entrée et le premier élément de sortie et étant reliés sélectivement à l’élément d’entrée par un embrayage d’entrée et au premier élément de sortie par un premier embrayage de sortie,  an intermediate element defining a rotor support, said intermediate element and said rotor being arranged in the direction of the transmission of torque between the input element and the first output element and being selectively connected to the input element by an input clutch and the first output member by a first output clutch,
- un organe d’actionnement avec une butée tournante associé à l’embrayage d’entrée,  an actuating member with a rotary stop associated with the input clutch,
- un carter de protection agencé pour envelopper au moins partiellement l’élément d’entrée de couple, l’élément de sortie de couple, la machine électrique tournante, l’élément intermédiaire et l’organe d’actionnement, et a protective casing arranged to at least partially enclose the torque input element, the torque output element, the rotating electrical machine, the intermediate element and the actuating member, and
- au moins un organe de roulement disposé radialement entre l’élément intermédiaire et le carter de protection, at least one rolling member arranged radially between the intermediate element and the protective casing,
dans lequel l’embrayage d’entrée, l’organe d’actionnement associé à l’embrayage d’entrée et l’au moins un organe de roulement se succèdent radialement en rapprochement de l’axe X. Cette configuration permet ainsi d’empiler les éléments radialement de sorte que l’on dispose d’un dispositif compact axialement. wherein the input clutch, the actuating member associated with the input clutch and the at least one rolling member radially alternate with each other in the direction of the X axis. This configuration thus makes it possible to stack the elements radially so that one has an axially compact device.
Au sens de l’invention, la succession radiale se comprend en termes de distance radiale.  In the sense of the invention, the radial succession is understood in terms of radial distance.
Dans la suite de la description et les revendications, on utilisera à titre non limitatif et afin d'en faciliter la compréhension, les termes « avant » ou « arrière » selon la direction par rapport à une orientation axiale déterminée par l’axe X principal de rotation de la transmission du véhicule automobile et les termes « intérieur /interne » ou « extérieur / externe » par rapport à l’axe X et suivant une orientation radiale, orthogonale à ladite orientation axiale.  In the remainder of the description and the claims, the terms "before" or "backward" depending on the direction with respect to an axial orientation determined by the principal axis X will be used in a nonlimiting manner and in order to facilitate understanding thereof. of rotation of the transmission of the motor vehicle and the terms "inner / inner" or "outer / outer" with respect to the axis X and in a radial orientation, orthogonal to said axial orientation.
Selon un autre aspect de l’invention, l’embrayage d’entrée, l’organe d’actionnement associé à l’embrayage d’entrée et un organe de roulement se succèdent radialement en rapprochement de l’axe X.  According to another aspect of the invention, the input clutch, the actuating member associated with the input clutch and a rolling member radially follow one another towards the X axis.
Selon un autre aspect de l’invention, le dispositif présente deux organes de roulements disposés radialement entre l’élément intermédiaire et le carter de protection. La présence de ces deux roulements permet d’obtenir un guidage amélioré du moteur électrique par le carter de protection.  According to another aspect of the invention, the device has two bearing members arranged radially between the intermediate element and the protective casing. The presence of these two bearings makes it possible to obtain improved guidance of the electric motor by the protective casing.
Selon un aspect de l’invention, ces organes de roulement sont disposés sur une même hauteur radiale. Avantageusement, les diamètres internes et externes des organes de roulement sont alors identiques.  According to one aspect of the invention, these rolling members are arranged on the same radial height. Advantageously, the inner and outer diameters of the rolling members are then identical.
Selon une variante, les deux organes de roulements sont disposés sur deux hauteurs radiales différentes.  According to one variant, the two bearing members are arranged on two different radial heights.
Selon un autre aspect de l’invention, les deux organes de roulement sont espacés axialement d’au moins 20 mm.  According to another aspect of the invention, the two rolling members are spaced axially by at least 20 mm.
Selon un autre aspect de l’invention, l’élément intermédiaire est porté uniquement par le carter de protection. Ainsi, la machine électrique est guidée en rotation uniquement par le carter de protection de façon optimisée et sans diminution de son efficacité dans le temps. En effet, le dispositif dispose d’une liaison mécanique, de type pivot, particulièrement robuste entre le rotor de la machine électrique, via le support de rotor, fonction occupée par l’élément intermédiaire, et le carter de protection comme élément fixe. L’au moins un organe de roulement est une liaison rotule et assure une liaison pivot indispensable au bon guidage de la machine électrique tournante. En effet, l'étude cinématique d'un organe de roulement (de manière générale un roulement à une rangée de billes) conduit à modéliser ce composant par une liaison rotule. Les actions mécaniques transmissibles par les contacts entre les billes et les bagues sont essentiellement radiales ou obliques et concourantes. Le torseur des actions mécaniques transmissibles par un roulement s'apparente donc à celui d'une liaison rotule. According to another aspect of the invention, the intermediate element is carried only by the protective casing. Thus, the electric machine is guided in rotation only by the protective casing optimally and without decreasing its effectiveness over time. Indeed, the device has a mechanical connection, pivot type, particularly robust between the rotor of the electric machine, via the rotor support, function occupied by the intermediate element, and the protective housing as a fixed element. The at least one rolling member is a ball joint and provides a pivot connection essential for the proper guidance of the rotating electrical machine. Indeed, the kinematic study of a rolling member (generally a single-row ball bearing) leads to modeling this component by a ball joint connection. The mechanical actions transmissible by the contacts between the balls and the rings are essentially radial or oblique and concurrent. The torsor of the mechanical actions transmissible by a bearing is therefore similar to that of a ball joint.
Avantageusement, l’au moins un organe de roulement est un roulement à une rangée de billes.  Advantageously, the at least one rolling member is a bearing with a row of balls.
Selon un autre aspect de l’invention, l’élément intermédiaire est porté par le carter de protection uniquement par l’intermédiaire d’au moins un organe de roulement. Ceci a pour avantage de diminuer le nombre de pièce intermédiaire entre le rotor et la pièce portant le rotor, en l’espèce le carter de protection. En effet, un trop grand nombre de pièces intermédiaires entraîne une augmentation de la chaîne de côte qui aboutit à une augmentation de l’écart entre le stator et le rotor et donc une diminution de l’efficacité via une baisse du champ magnétique. Ainsi, selon cet aspect, seul le ou les organes de roulement constituent les pièces intermédiaires entre le carter de protection et l’élément intermédiaire lorsque ce dernier est porté par le carter.  According to another aspect of the invention, the intermediate element is carried by the protective casing only via at least one rolling member. This has the advantage of reducing the number of intermediate piece between the rotor and the part carrying the rotor, in this case the protective housing. Indeed, too many intermediate parts leads to an increase in the side chain that results in an increase in the gap between the stator and the rotor and therefore a decrease in efficiency via a drop in the magnetic field. Thus, according to this aspect, only the rolling element or members constitute the intermediate parts between the protective casing and the intermediate element when the latter is carried by the casing.
En variante, l’élément intermédiaire est porté par le carter de protection par l’intermédiaire d’au moins un organe de roulement et d’une pièce supplémentaire, ladite pièce étant de préférence l’élément d’entrée de couple. . Ainsi, selon cet aspect, le ou les organes de roulement ne constituent pas les seules pièces intermédiaires entre le carter de protection et l’élément intermédiaire lorsque ce dernier est porté par le carter.  Alternatively, the intermediate element is carried by the protective casing via at least one rolling member and an additional piece, said part preferably being the torque input member. . Thus, according to this aspect, the rolling element or members are not the only intermediate parts between the protective casing and the intermediate element when the latter is carried by the casing.
Selon un autre aspect de l’invention, l’au moins un organe de roulement comporte une bague intérieur et une bague extérieure, ladite bague intérieure étant au contact avec l’élément intermédiaire et ladite bague extérieure étant au contact avec le carter de protection.  According to another aspect of the invention, the at least one rolling member comprises an inner ring and an outer ring, said inner ring being in contact with the intermediate element and said outer ring being in contact with the protective casing.
Selon un autre aspect de l’invention, le dispositif comprend en outre un organe d’actionnement avec une butée tournante associé au premier embrayage de sortie, dans lequel le premier embrayage d’entrée, l’organe d’actionnement associé au premier embrayage de sortie, l’organe d’actionnement associé à l’embrayage d’entrée et l’au moins un organe de roulement se succèdent radialement en rapprochement de l’axe X. According to another aspect of the invention, the device further comprises an actuating member with a rotary stop associated with the first output clutch, wherein the first input clutch, the associated actuating member. the first output clutch, the actuating member associated with the input clutch and the at least one rolling member radially succeed each other in approaching the X axis.
Selon un autre aspect de l’invention, le premier embrayage d’entrée, l’organe d’actionnement associé au premier embrayage de sortie, l’organe d’actionnement associé à l’embrayage d’entrée sont situé d’un premier coté du dispositif 1 , avantageusement coté moteur thermique.  According to another aspect of the invention, the first input clutch, the actuating member associated with the first output clutch, the actuating member associated with the input clutch are located on a first side. of the device 1, advantageously side thermal engine.
Selon un autre aspect de l’invention, l’au moins un organe de roulement est disposé entre une extrémité radiale du carter de protection et une portion axiale de l’élément intermédiaire.  According to another aspect of the invention, the at least one rolling member is disposed between a radial end of the protective housing and an axial portion of the intermediate element.
Selon un autre aspect de l’invention, le dispositif comprend en outre :  According to another aspect of the invention, the device further comprises:
- un deuxième élément de sortie de couple, apte à être couplé en rotation à un deuxième arbre d’entrée d’une boite de vitesses, ledit deuxième élément de sortie étant disposé en parallèle du premier élément de sortie de couple au sens de la transmission de couple, le rotor étant relié sélectivement au deuxième élément de sortie par un deuxième embrayage de sortie et a second torque output element, able to be coupled in rotation to a second input shaft of a gearbox, said second output element being arranged in parallel with the first torque output element in the transmission direction; of torque, the rotor being selectively connected to the second output member by a second output clutch and
- un troisième organe d’actionnement avec une butée tournante associé au deuxième embrayage de sortie. - A third actuating member with a rotary stop associated with the second output clutch.
Selon un autre aspect de l’invention, le premier embrayage de sortie, le deuxième embrayage de sortie et l’organe d’actionnement associé au deuxième embrayage de sortie se succèdent radialement en rapprochement de l’axe X.  According to another aspect of the invention, the first output clutch, the second output clutch and the actuating member associated with the second output clutch are successively radially close to the X axis.
Selon un autre aspect de l’invention, le premier embrayage de sortie, le deuxième embrayage de sortie et l’organe d’actionnement associé au deuxième embrayage de sortie sont situé d’un second coté du dispositif, avantageusement, coté boite de vitesses. Ainsi, un tel dispositif peut être considéré comme extrêmement compact radialement et axialement. En effet, les embrayages et les organes d’actionnement sont répartis équitablement de manière à réduire au maximum l’encombrement axial et radial.  According to another aspect of the invention, the first output clutch, the second output clutch and the actuating member associated with the second output clutch are situated on a second side of the device, advantageously on the gearbox side. Thus, such a device can be considered extremely compact radially and axially. Indeed, the clutches and the actuating members are equitably distributed so as to minimize the axial and radial dimensions.
Au sens de la présente demande, le premier embrayage de sortie est celui situé radialement à l’extérieur, c'est-à-dire le plus loin de l’axe de rotation X du dispositif. Le deuxième embrayage de sortie étant celui situé radialement à l’intérieur, c'est-à-dire le plus proche de l’axe de rotation du dispositif. Selon un autre aspect de l’invention, il existe un plan perpendiculaire à l’axe de rotation qui coupe à la fois le premier embrayage de sortie, le deuxième embrayage de sortie et l’organe d’actionnement associé au deuxième embrayage de sortie. For the purposes of the present application, the first output clutch is that located radially outward, that is to say the furthest from the axis of rotation X of the device. The second outlet clutch being that located radially inward, that is to say the closest to the axis of rotation of the device. According to another aspect of the invention, there is a plane perpendicular to the axis of rotation which intersects both the first output clutch, the second output clutch and the actuating member associated with the second output clutch.
Selon une caractéristique supplémentaire de l’invention, l’embrayage d’entrée et/ou les premier et deuxième embrayages de sortie comprennent :  According to a further feature of the invention, the input clutch and / or the first and second output clutches comprise:
- un porte-disque d’entrée solidaire en rotation de l’élément d’entrée de couple pour l’embrayage d’entrée, et solidaire en rotation du voile d’entrée pour le premier embrayage de sortie,  an input disk carrier integral in rotation with the torque input element for the input clutch, and integral in rotation with the entry web for the first output clutch,
- un porte-disque de sortie solidaire en rotation du voile d’entrée pour l’embrayage d’entrée, et solidaire en rotation du premier élément de sortie pour le premier embrayage de sortie, et  an outlet disk carrier integral in rotation with the entry web for the input clutch, and integral in rotation with the first output element for the first output clutch, and
- un ensemble multidisque comprenant au moins un disque de friction solidaire en rotation de l’un des porte-disque d’entrée et de sortie, au moins deux plateaux respectivement disposés de part et d’autre de chaque disque de friction, solidaires en rotation de l’autre des porte-disque d’entrée et de sortie et des garnitures de friction disposées entre les plateaux et un disque de friction, l’embrayage d’entrée et/ou le premier embrayage de sortie décrivant une position débrayée et une position embrayée dans laquelle lesdits plateaux et le disque de friction pincent les garnitures de friction de manière à transmettre un couple entre le porte-disque d’entrée et le porte-disque de sortie.  a multi-disk assembly comprising at least one friction disk integral in rotation with one of the input and output disk carriers, at least two plates respectively arranged on either side of each friction disk, integral in rotation on the other hand, inlet and outlet disc holders and friction linings disposed between the platens and a friction disc, the input clutch and / or the first output clutch describing a disengaged position and a position engaged in which said trays and the friction disk pinch the friction liners so as to transmit torque between the input disk carrier and the output disk carrier.
Selon un autre aspect de l’invention, l’élément intermédiaire définit en outre le porte-disque de sortie de l’embrayage d’entrée et le porte-disque d’entrée du premier embrayage de sortie. Ainsi, l’élément intermédiaire définit à la fois le support de rotor, le porte-disque de sortie de l’embrayage d’entrée et le porte-disque d’entrée du premier embrayage de sortie. Ceci permet donc de limiter le nombre de pièces et facilite le montage.  According to another aspect of the invention, the intermediate element further defines the output disk carrier of the input clutch and the input disk carrier of the first output clutch. Thus, the intermediate element defines both the rotor support, the output clutch of the input clutch and the input disk carrier of the first output clutch. This therefore limits the number of parts and facilitates assembly.

Un dispositif d’amortisseur de torsion (non représenté) peut être positionné entre le vilebrequin du moteur thermique et l’élément d’entrée de couple 2.  A torsion damper device (not shown) can be positioned between the crankshaft of the engine and the torque input member 2.
Le dispositif comprend également une machine électrique tournante 12 comprenant un rotor 13 et un stator 14. Le stator 14 est fixe et disposé autour du rotor 13. Le rotor 13 est disposé au sens de la transmission de couple entre l’élément d’entrée de couple 2 d’une part et le premier élément de sortie 3 d’autre part.  The device also comprises a rotating electrical machine 12 comprising a rotor 13 and a stator 14. The stator 14 is fixed and arranged around the rotor 13. The rotor 13 is arranged in the direction of the transmission of torque between the input element of the couple 2 on the one hand and the first output element 3 on the other.
Dans l’exemple considéré, la machine électrique tournante 12 est une machine synchrone à aimants permanents.  In the example considered, the rotating electrical machine 12 is a synchronous machine with permanent magnets.
Le rotor 13 de la machine électrique tournante est relié sélectivement à l’élément d’entrée 2 par un embrayage d’entrée 10, au premier élément de sortie 3 par un premier embrayage de sortie 20, et au deuxième élément de sortie 4 par un deuxième embrayage de sortie 30.  The rotor 13 of the rotating electrical machine is selectively connected to the input element 2 by an input clutch 10, to the first output element 3 by a first output clutch 20, and to the second output element 4 by a second output clutch 30.

In the example considered, an additional piece 19 secured to the intermediate element 5 is provided as a rotor support. Alternatively, the rotor is disposed directly on the intermediate member 5 without additional parts.
Ainsi, l’élément intermédiaire 5 maintient la machine électrique tournante 12 en rotation. La machine électrique tournante 12 est alors appelée « in-line », c'est-à- dire que l’axe de rotation de la machine électrique tournante 12 est confondu avec l’axe de rotation X du dispositif 1 de transmission de couple. Thus, the intermediate element 5 keeps the rotating electrical machine 12 in rotation. The rotating electrical machine 12 is then called "in-line", that is, say that the axis of rotation of the rotating electrical machine 12 coincides with the axis of rotation X of the torque transmission device 1.

Each disc holder 11, 12 has a cylindrical skirt on which the trays and the friction discs are mounted.
Les disques de friction de l’ensemble multidisque 13 coopèrent avec la jupe cylindrique du porte-disque d’entrée 11 selon leur périphérie radialement intérieure par cannelures. Les disques de friction sont donc radialement à l’extérieur de la jupe cylindrique.  The friction discs of the multi-disc assembly 13 cooperate with the cylindrical skirt of the input disc carrier 11 along their radially inner periphery by fluting. The friction discs are radially outwardly of the cylindrical skirt.
Les plateaux de l’ensemble multidisque 13 coopèrent avec la jupe cylindrique du porte-disque de sortie 12 selon leur périphérie radialement extérieur par cannelures. Les plateaux sont donc radialement à l’intérieur de la jupe cylindrique.  The trays of the multi-disk assembly 13 cooperate with the cylindrical skirt of the output disk carrier 12 according to their radially outer periphery by fluting. The trays are therefore radially inside the cylindrical skirt.
Dans l’exemple considéré, le dispositif comprend également un premier embrayage de sortie 20 accouplant sélectivement et par friction l’élément intermédiaire 5 et le premier élément de sortie 3.  In the example considered, the device also comprises a first output clutch 20 selectively and frictionally coupling the intermediate element 5 and the first output element 3.
Ainsi, le premier embrayage de sortie 20 comprend :  Thus, the first output clutch 20 comprises:
- un porte-disque d’entrée 21 défini par l’élément intermédiaire 5, - un porte-disque de sortie 22 solidaire en rotation du premier élément de sortie 3 et, an input disk carrier 21 defined by the intermediate element 5, an outlet disk carrier 22 integral in rotation with the first output element 3 and,

Les disques de friction de l’ensemble multidisque 23 coopèrent avec la jupe cylindrique du porte-disques de sortie 22 selon leur périphérie radialement extérieure par cannelures. Les disques de friction sont donc radialement à l’intérieur de la jupe cylindrique.  The friction discs of the multidisk assembly 23 cooperate with the cylindrical skirt of the output disk carrier 22 according to their radially outer periphery by fluting. The friction discs are therefore radially inside the cylindrical skirt.
Les plateaux de l’ensemble multidisque 23 coopèrent avec la jupe cylindrique du porte-disque d’entrée 21 selon leur périphérie radialement extérieur par cannelures. Les plateaux sont donc radialement à l’intérieur de la jupe cylindrique.  The trays of the multidisk assembly 23 cooperate with the cylindrical skirt of the inlet disk carrier 21 according to their radially outer periphery by splines. The trays are therefore radially inside the cylindrical skirt.
Dans l’exemple considéré, le dispositif 1 comprend un deuxième embrayage de sortie 30, accouplant sélectivement et par friction l’élément intermédiaire 5 et le premier élément de sortie 4.  In the example considered, the device 1 comprises a second output clutch 30, selectively and frictionally coupling the intermediate element 5 and the first output element 4.

L’ensemble multidisque 33 présente les mêmes caractéristiques techniques que l’ensemble multidisque de l’embrayage 20. In the example under consideration, although they are two different parts, the intermediate element 5 also defines the input disk carrier of the second output clutch 30. The multi-disk assembly 33 has the same technical characteristics as the multi-disk assembly of the clutch 20.
De manière commune aux trois embrayages 10, 20 et 30, les garnitures peuvent être fixées sur les disques de friction, notamment par collage, notamment par rivetage, notamment par surmoulage. En variante, les garnitures sont fixées sur les plateaux.  In common with the three clutches 10, 20 and 30, the linings can be fixed to the friction discs, in particular by gluing, in particular by riveting, in particular by overmolding. Alternatively, the fittings are fixed on the trays.
Chaque porte-disque 11 , 12, 21 , 22, 31 , 32 peut synchroniser en rotation l’ensemble des plateaux ou l’ensemble des disques de friction.  Each disk carrier 11, 12, 21, 22, 31, 32 can synchronize in rotation all the trays or all of the friction discs.

En variante, les plateaux peuvent être solidaires en rotation du porte-disque de sortie 12, 22, 32. Les disques peuvent être solidaires en rotation du porte-disque d’entrée 1 1 , 21 , 31 .  According to one aspect of the invention, the trays can be integral in rotation with the input disk carrier 11, 21, 31 and the friction disks can be integral with the output disk carrier 12, 22, 32. Alternatively, the plates can be integral in rotation with the output disk carrier 12, 22, 32. The disks can be integral in rotation with the input disk carrier 1 1, 21, 31.
Les embrayages sont de type humide et comportent entre deux et sept disques de friction, de préférence quatre disques de friction. De tels embrayages multi-disques permettent de limiter la hauteur radiale de limiter l’étendue axiale.  The clutches are wet type and have between two and seven friction discs, preferably four friction discs. Such multi-disk clutches can limit the radial height to limit the axial extent.
Les embrayages de sortie 20, 30 peuvent être agencés pour ne pas être simultanément dans la même configuration embrayée. En revanche, ils peuvent simultanément être configurés dans leur position débrayée.  The output clutches 20, 30 may be arranged not to be simultaneously in the same engaged configuration. On the other hand, they can simultaneously be configured in their disengaged position.
Dans l’exemple considéré, le premier embrayage de sortie 20 et le deuxième embrayage de sortie 30 se succèdent radialement en rapprochement de l’axe X.

L’organe de transmission de force 51 est mobile axialement pour transmettre l’effort d’actionnement de l’organe d’actionnement 50 vers l’embrayage d’entrée 20. In the example considered, the device 1 also comprises an actuating member 50, in particular an actuating device with a rotary stop and a force transmission member 51 associated with the first output clutch 20. The force transmission member 51 is axially movable to transmit the actuating force of the actuating member 50 to the input clutch 20.
Avantageusement, le premier embrayage d’entrée 10, l’organe d’actionnement 50 associé au premier embrayage de sortie 20, l’organe d’actionnement 40 associé à l’embrayage d’entrée 10 et au moins un organe de roulement 47 se succèdent radialement en rapprochement de l’axe X.  Advantageously, the first input clutch 10, the actuating member 50 associated with the first output clutch 20, the actuating member 40 associated with the input clutch 10 and at least one rolling member 47 follow radially towards the X axis.
Le dispositif 1 comprend également un organe d’actionnement 60 et un organe de transmission de force 61 associé au deuxième embrayage de sortie 30. L’organe de transmission de force 61 est mobile axialement pour transmettre l’effort d’actionnement de l’organe d’actionnement 60 vers le deuxième embrayage de sortie 30.  The device 1 also comprises an actuating member 60 and a force transmission member 61 associated with the second output clutch 30. The force transmission member 61 is axially movable to transmit the actuating force of the organ actuating device 60 to the second output clutch 30.
Un organe de maintien en position débrayée, tel qu’un ressort hélicoïdal peut être prévu pour repousser les organes de transmission de force 51 , 61 des embrayages de sortie 20, 30. Les embrayages de sortie 20, 30 sont de type « normalement ouvert ».  A holding member in the disengaged position, such as a coil spring can be provided to push the force transmission members 51, 61 of the output clutches 20, 30. The output clutches 20, 30 are of the "normally open" type .
Ces organes d’actionnement 50, 60 reprennent les mêmes éléments que ceux détaillés en lien avec l’organe d’actionnement 40 de l’embrayage d’entrée.  These actuating members 50, 60 have the same elements as those detailed in connection with the actuating member 40 of the input clutch.
Dans l’exemple considéré, les organes d’actionnement 40 et 50 sont logés dans une même enveloppe et ne forment qu’un seul et même composant appelé classiquement système hydraulique de commande ou double actionneur concentrique. Ainsi, les organes d’actionnement 40 et 50, en particulier leur chambre d’actionnement, ainsi que l’embrayage d’entrée 10 sont empilés radialement coté moteur thermique tandis que l’organe d’actionnement 60 et les embrayages de sortie 20 et 30 sont empilés radialement coté boite de vitesses. Cette architecture contribue à la compacité axiale et radiale du dispositif.  In the example considered, the actuating members 40 and 50 are housed in the same envelope and form a single component conventionally called hydraulic control system or double concentric actuator. Thus, the actuating members 40 and 50, in particular their actuating chamber, as well as the input clutch 10 are stacked radially on the thermal engine side while the actuating member 60 and the output clutches 20 and 30 are stacked radially next gearbox. This architecture contributes to the axial and radial compactness of the device.
Selon une variante, les organes d’actionnement 50 et 60 sont logés dans une même enveloppe et ne forment qu’un seul et même composant appelé classiquement système hydraulique de commande ou double actionneur concentrique. Les formes des pistons et/ou des organes d’actionnement 40, 50, 60 sont choisis de sorte qu’ils puissent s’empiler radialement ce qui contribue à la compacité axiale du dispositif 1. Les organes de transmission de force 41 , 51 , 61 des embrayages 10, 20, 30 présentent chacun une extrémité radiale extérieure recourbée définissant une surface d’appui pour exercer l’effort axial sur les ensemble multidisques, 13, 23, 33. L’actionnement est ainsi de type « poussé ». According to a variant, the actuating members 50 and 60 are housed in one and the same envelope and form a single component conventionally called hydraulic control system or double concentric actuator. The shapes of the pistons and / or the actuating members 40, 50, 60 are chosen so that they can be stacked radially, which contributes to the axial compactness of the device 1. The force transmission members 41, 51, 61 of the clutches 10, 20, 30 each have a curved outer radial end defining a bearing surface for exerting the axial force on the multi-disk assemblies, 13, 23, 33. Actuation is thus of the "pushed" type.
Dans l’exemple considéré, l’extrémité radiale extérieure de trois organes de transmission de force 41 , 51 , 61 comporte une pluralité de doigts d’extension axiale, respectivement numérotés 73, 53, 63, et reparties autour de l’axe X de sorte que leur surface d’appui est discontinue. Dans l’exemple considéré, les doigts 73, 53 passent ici au travers d’ouvertures ménagées dans l’élément intermédiaire 5.  In the example considered, the outer radial end of three force transmission members 41, 51, 61 comprises a plurality of axial extension fingers, respectively numbered 73, 53, 63, and distributed around the X axis of so that their bearing surface is discontinuous. In the example considered, the fingers 73, 53 pass here through openings in the intermediate element 5.
Ces doigts 73, 53, permettent aux organes de transmission de force 41 , 51 , de pouvoir actionner l’ensemble multidisque au travers de l’élément intermédiaire 5.  These fingers 73, 53 allow the force-transmitting members 41, 51 to be able to actuate the multi-disk assembly through the intermediate element 5.
La figure 2 décrit un second mode de réalisation selon l’invention similaire à celui de la figure 1 . Une différence dans l’exemple considéré réside dans le fait que l’élément intermédiaire 5 est porté par le carter de protection 46 par l’intermédiaire de deux organes de roulement 47 et d’une pièce supplémentaire, en l’occurrence l’élément d’entrée de couple 2.  FIG. 2 describes a second embodiment according to the invention similar to that of FIG. A difference in the example considered lies in the fact that the intermediate element 5 is carried by the protective casing 46 by means of two rolling members 47 and an additional piece, in this case the element d torque input 2.
En outre, la machine électrique 12 est porté à la fois par le carter de protection 46 via les organes de roulement 47, l’élément d’entrée de couple 2 et l’élément intermédiaire 5 d’une part et le porte-disque d’entrée 21 , 31 des embrayages de sortie 20, 30 et un autre organe de roulement 48 d’autre part.  In addition, the electrical machine 12 is carried both by the protective casing 46 via the rolling members 47, the torque input element 2 and the intermediate element 5 on the one hand and the disc carrier inlet 21, 31 of the outlet clutches 20, 30 and another bearing member 48 on the other hand.
L’organe de roulement 48 et les embrayages de sortie 20, 30 sont empilés radialement.  The rolling member 48 and the outlet clutches 20, 30 are stacked radially.
Dans l’exemple considéré, les organes d’actionnement 50 et 60 sont logés dans une même enveloppe et ne forment qu’un seul et même composant appelé classiquement système hydraulique de commande ou double actionneur concentrique.  In the example considered, the actuating members 50 and 60 are housed in the same casing and form a single component conventionally called hydraulic control system or double concentric actuator.
Dans l’exemple considéré, le premier embrayage de sortie 20, le deuxième embrayage de sortie 30, l’organe d’actionnement 50 et l’organe d’actionnement 60 se succèdent radialement en rapprochement de l’axe X.  In the example considered, the first output clutch 20, the second output clutch 30, the actuating member 50 and the actuating member 60 radially alternate with each other in the direction of the X axis.
Dans l’exemple considéré, il existe un plan perpendiculaire à l’axe X qui coupe à la fois l’embrayage d’entrée 10, l’organe d’actionnement 40 associé à l’embrayage d’entrée 10 et l’au moins un organe de roulement 47. Bien que l'invention ait été décrite en liaison avec plusieurs modes de réalisation particuliers, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. In the example considered, there is a plane perpendicular to the X axis which intersects both the input clutch 10, the actuating member 40 associated with the input clutch 10 and the at least one a rolling member 47. Although the invention has been described in connection with several particular embodiments, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
