« DISPOSITIF DE TRANSMISSION POUR VEHICULE A MOTORISATION "TRANSMISSION DEVICE FOR MOTOR VEHICLE

HYBRIDE »HYBRID »

La présente invention concerne un dispositif de transmission pour véhicule à motorisation hybride.The present invention relates to a transmission device for hybrid drive vehicle.

Un dispositif de transmission hybride peut transmettre une puissance mécanique à au moins une roue motrice d'un véhicule à partir de différentes sources d'énergie.A hybrid transmission device can transmit mechanical power to at least one driving wheel of a vehicle from different energy sources.

En référence à la figure 1, un tel dispositif peut utiliser comme sources d'énergie un moteur thermique 1 et des machines électriques 2 et 3.With reference to FIG. 1, such a device can use as energy sources a heat engine 1 and electric machines 2 and 3.

Le dispositif fournit à un arbre 4 de roue 5 une puissance mécanique issue d'une sortie 11 du moteur 1 thermique et/ou des arbres 8 et 9 respectifs des machines électriques 2 et 3.The device supplies a wheel shaft 4 with mechanical power from an output 11 of the thermal engine 1 and / or the respective shafts 8 and 9 of the electric machines 2 and 3.

Le fonctionnement d'un tel dispositif est décrit en détail dans la demande de brevet FR2883515 dont le contenu est incorporé à cette demande par référence.The operation of such a device is described in detail in the patent application FR2883515 whose contents are incorporated in this application by reference.

D'une façon générale, le dispositif 1 comprend : - un arbre d'entrée 10, également dénommé arbre primaire, relié à la sortie 11 du moteur thermique 1 et un arbre de sortie 12 relié à l'arbre 4 de roue 5.In general, the device 1 comprises: an input shaft 10, also called primary shaft, connected to the output 11 of the heat engine 1 and an output shaft 12 connected to the wheel shaft 4.

- un ensemble mécanique, délimité par une ligne fermée en trait mixte, la reliant entre eux l'arbre primaire 10, l'arbre de sortie 12 et les arbres 8 et 9 des machines 2 et 3.a mechanical assembly, delimited by a closed line in broken lines, connecting it to each other the primary shaft 10, the output shaft 12 and the shafts 8 and 9 of the machines 2 and 3.

L'ensemble mécanique la est formé par au moins deux trains épicycloïdaux 13 et 14 comportant un porte-satellites commun 15 qui entraîne six axes (trois axes par train disposés à 120° les uns par rapport aux autres) dont uniquement quatre axes 16 à 19 sont représentés, et six satellites (trois satellites par train disposés à 120° les uns par rapport aux autres) dont uniquement quatre satellites 20a, 20b, 21a et 21b sont représentés. Cet ensemble la comprend également un premier dispositif de commutation 22, délimité par une ligne fermée en trait mixte, comportant des moyens 22a, 22b, 22c et 22d pour relier l'arbre 8 de la machine électrique 2 soit à l'arbre primaire 10 soit à un élément 27 du train épicycloïdal 14.The mechanical assembly la is formed by at least two planetary gear trains 13 and 14 comprising a common planet carrier 15 which drives six axes (three axes per train arranged at 120 ° relative to each other) of which only four axes 16 to 19 are shown, and six satellites (three satellites per train arranged at 120 ° relative to each other) of which only four satellites 20a, 20b, 21a and 21b are shown. This assembly also comprises a first switching device 22, delimited by a closed line in dotted lines, comprising means 22a, 22b, 22c and 22d to connect the shaft 8 of the electrical machine 2 to either the primary shaft 10 or to an element 27 of the epicyclic gear train 14.

De façon analogue, cet ensemble la comprend un second dispositif de commutation 28 , délimité par une ligne fermée en trait mixte, comportant des moyens 28a, 28b, 28c et 28d pour relier l'arbre 9 de la machine électrique 3 soit à une couronne 25, directement reliée à l'arbre de sortie 12, soit à un élément 26 du train épicycloïdal 13. Grâce aux dispositifs de commutation 22 et 28, un tel dispositif peut être mis en œuvre selon trois modes de fonctionnement :Similarly, this assembly includes a second switching device 28 delimited by a closed line in dotted lines, comprising means 28a, 28b, 28c and 28d for connecting the shaft 9 of the electric machine 3 to a ring 25. , directly connected to the output shaft 12, or to an element 26 of the epicyclic gear train 13. Thanks to the switching devices 22 and 28, such a device can be implemented according to three modes of operation:

- Dans un premier mode de fonctionnement, on relie l'arbre 8 de la première machine 2 à l'élément 27 du train épicycloïdal 14 et l'arbre 9 de la deuxième machine 3 à la couronne 25.In a first mode of operation, the shaft 8 of the first machine 2 is connected to the element 27 of the epicyclic gear train 14 and the shaft 9 of the second machine 3 to the ring gear 25.

- Dans un deuxième mode de fonctionnement, on relie l'arbre 8 de la première machine 2 à l'élément 27 du train épicycloïdal 14 et l'arbre 9 de la deuxième machine 3 à l'élément 26 du train épicycloïdal 13.In a second mode of operation, the shaft 8 of the first machine 2 is connected to the element 27 of the epicyclic gear train 14 and the shaft 9 of the second machine 3 to the element 26 of the epicyclic gear train 13.

- Dans un troisième mode de fonctionnement, on relie l'arbre 8 de la première machine 2 à l'arbre primaire 10 et l'arbre 9 de la deuxième machine 3 à l'élément 26 du train épicycloïdal 13. Ces différents modes de fonctionnement peuvent être mis en œuvre successivement de façon à modifier en continu le rapport de transmission entre les arbres de sortie des machines électriques 2 et 3 et l'arbre 4 de roue 5.- In a third mode of operation, the shaft 8 of the first machine 2 is connected to the primary shaft 10 and the shaft 9 of the second machine 3 to the element 26 of the epicyclic gear train 13. These different operating modes can be implemented successively so as to continuously change the transmission ratio between the output shafts of the electric machines 2 and 3 and the wheel shaft 4.

Toutefois, un tel dispositif présente des inconvénients lorsque le véhicule fonctionne uniquement à partir de la puissance fournie par une ou par les deux machines électriques 2 ou 3.However, such a device has drawbacks when the vehicle only operates from the power supplied by one or both electric machines 2 or 3.

De fait, le moteur thermique doit être maintenu arrêté lorsque le véhicule fonctionne selon un mode électrique, notamment pour diminuer la consommation du véhicule.In fact, the heat engine must be kept stopped when the vehicle operates in an electric mode, in particular to reduce the consumption of the vehicle.

Or, l'arbre primaire 10 du moteur thermique peut être entraîné par les machines électriques, notamment lorsque la machine 2 fournit de la puissance par l'intermédiaire de cet arbre primaire 10.However, the primary shaft 10 of the engine can be driven by the electric machines, especially when the machine 2 provides power through this primary shaft 10.

Dans ces cas, un démarrage intempestif du moteur thermique peut se produire et perturber la conduite et le fonctionnement du véhicule.In these cases, an inadvertent start of the engine may occur and disrupt the driving and operation of the vehicle.

Indépendamment du mode de fonctionnement des machines 2 et 3, une partie de la puissance fournie par ces machines 2 et 3 est utilisée pour empêcher le démarrage du moteur thermique afin de le maintenir à l'arrêt. Dès lors, le rendement du véhicule est abaissé par cette utilisation de puissance électrique tandis que le contrôle de la puissance effectivement fournie à l'arbre 4 de roue 5 est rendu plus complexe.Regardless of the mode of operation of the machines 2 and 3, a portion of the power provided by these machines 2 and 3 is used to prevent the starting of the engine to keep it at a standstill. Therefore, the efficiency of the vehicle is lowered by this use of electric power while the control of the power actually supplied to the wheel shaft 4 is made more complex.

Un autre problème réside dans les positions variables de fonctionnement des machines électriques 2 et 3. De fait, ces dernières peuvent fournir de la puissance à la roue 5 en occupant les positions distinctes décrites précédemment.Another problem lies in the variable operating positions of the electrical machines 2 and 3. In fact, the latter can supply power to the wheel 5 by occupying the distinct positions described above.

Or, ces variations de positions de fonctionnement peuvent provoquer des variations de la puissance fournie à la roue 5, ces variations pouvant nuire à l'agrément de conduite du véhicule.However, these variations in operating positions may cause variations in the power supplied to the wheel 5, these variations may impair the driveability of the vehicle.

La présente invention, qui permet de pallier à au moins un des inconvénients cités ci-dessus, porte sur un dispositif de transmission de puissance pour véhicule hybride, ce dispositif comprenant :The present invention, which makes it possible to overcome at least one of the disadvantages mentioned above, relates to a power transmission device for a hybrid vehicle, this device comprising:

- un ensemble mécanique reliant un arbre primaire relié à la sortie d'un moteur thermique, un arbre de sortie et des arbres de machines électriques, cet ensemble comprenant au moins deux trains épicycloïdaux munis d'un porte-satellites commun qui entraîne des axes et des satellites, des premiers moyens de commutation pour relier l'arbre d'une première machine électrique soit directement soit indirectement à une couronne reliée à un arbre de roue, - des moyens pour bloquer la rotation de l'arbre primaire .a mechanical assembly connecting a primary shaft connected to the output of a heat engine, an output shaft and shafts of electrical machines, this assembly comprising at least two planetary gear trains provided with a common planet carrier which drives axes and satellites, first switching means for connecting the shaft of a first electrical machine either directly or indirectly to a ring gear connected to a wheel shaft; means for locking the rotation of the primary shaft.

Grâce à sa structure, un tel dispositif permet d'empêcher le démarrage du moteur thermique en bloquant toute rotation de l'arbre primaire sans sollicitation des machines électrique.Thanks to its structure, such a device allows to prevent the starting of the engine by blocking any rotation of the primary shaft without stressing the electrical machines.

De plus, comme aucune puissance électrique n'est requise pour empêcher cette rotation, le rendement d'un dispositif conforme à l'invention est accru par rapport à un dispositif conforme à l'art antérieur.In addition, since no electric power is required to prevent this rotation, the efficiency of a device according to the invention is increased compared to a device according to the prior art.

Le blocage peut être réalisé de différentes manières, par exemple au moyen d'un système de cliquets, d'un système de roue libre, de frein ou de tout autre moyen de blocage en rotation d'un arbre tournant.The locking can be achieved in various ways, for example by means of a system of pawls, a freewheel system, brake or any other means of locking in rotation of a rotating shaft.

De préférence, le dispositif comprend des moyens pour que le blocage de l'arbre primaire soit mis en œuvre lorsque le moteur thermique est à l'arrêt. Avantageusement, le dispositif comprend des moyens de commutation pour relier l'arbre d'une deuxième machine électrique soit à l'arbre primaire soit à un planétaire d'un train épicycloïdal .Preferably, the device comprises means for locking the primary shaft is implemented when the engine is stopped. Advantageously, the device comprises switching means for connecting the shaft of a second electrical machine either to the primary shaft or to a sun gear of an epicyclic gear train.

Dans ce cas, le dispositif peut comprendre des moyens pour maintenir l'arbre de la deuxième machine électrique en liaison avec le planétaire lorsque l'arbre primaire est bloqué .In this case, the device may comprise means for maintaining the shaft of the second electrical machine in connection with the sun gear when the primary shaft is blocked.

L' invention concerne également un procédé de transmission de puissance pour véhicule hybride, ce procédé comprenant les étapes de : relier un arbre primaire relié à la sortie d'un moteur thermique, un arbre de sortie et des arbres de machines électriques par un ensemble comprenant au moins deux trains épicycloïdaux munis d'un porte-satellites commun qui entraîne des axes et des satellites,The invention also relates to a power transmission method for a hybrid vehicle, the method comprising the steps of: connecting a primary shaft connected to the output of a heat engine, an output shaft and electric machine shafts by an assembly comprising at least two planetary gear trains provided with a common planet carrier which drives axes and satellites,

Preferably, the method comprises the step of blocking the primary shaft when the heat engine is stopped.

Avantageusement, le procédé comprend l'étape de commuter l'arbre d'une deuxième machine électrique soit vers l'arbre primaire soit vers un planétaire d'un train épicycloïdal lorsque le moteur thermique fonctionne.Advantageously, the process comprises the step of to switch the shaft of a second electric machine either towards the primary shaft or towards a sun gear of an epicyclic gear train when the heat engine is running.

De préférence, le procédé comprend l'étape de maintenir l'arbre de la deuxième machine électrique en liaison avec le planétaire lorsque l'arbre primaire est bloqué .Preferably, the method comprises the step of maintaining the shaft of the second electrical machine in connection with the sun gear when the primary shaft is blocked.

L'invention sera mieux comprise et d'autres buts, avantages et caractéristiques apparaîtront plus clairement à la lecture de la description qui suit et qui est faite au regard des dessins annexés et sur lesquels : la figure 1, déjà décrite, est une illustration schématique d'un dispositif connu de transmission pour véhicule à motorisation hybride, - les figures 2A, 2B et 2C sont des schémas d'un dispositif conforme à l'invention mis en œuvre selon un premier mode d'utilisation, et les figures 3A, 3B et 3C sont des schémas du dispositif des figures 2A, 2B et 2C mis en œuvre selon un second mode d'utilisation.The invention will be better understood and other objects, advantages and features will appear more clearly on reading the description which follows and which is made with reference to the appended drawings and in which: FIG. 1, already described, is a diagrammatic illustration of a known transmission device for a vehicle with hybrid drive, - FIGS. 2A, 2B and 2C are diagrams of a device according to the invention implemented according to a first mode of use, and FIGS. 3A, 3B and 3C are diagrams of the device of FIGS. 2A, 2B and 2C implemented according to a second mode of use.

Un dispositif de transmission de puissance pour véhicule hybride conforme à l'invention est décrit ci- dessous lors de son utilisation dans un mode électrique pur, la puissance fournie à ce dispositif provenant uniquement d'une ou de deux machines électriques.A hybrid vehicle power transmission device according to the invention is described below when used in a pure electric mode, the power supplied to this device coming only from one or two electrical machines.

C'est pourquoi, le moteur thermique du dispositif n'est pas représenté dans les figures 2A, 2B, 2C, 3A, 3B et 3C décrivant le fonctionnement de ce dispositif dans ce mode électrique . Toutefois, l'arbre primaire 31 d'un tel moteur thermique est représenté bloqué sur ces figures, conformément à l'invention, à l'aide de moyens 60. Ces moyens peuvent être, par exemple, des éléments de serrage commandés électroniquement. De ce fait, le nombre de positions de fonctionnement du dispositif est limité car une des machines électriques ne peut plus transmettre de puissance à travers cet arbre primaire, comme décrit ci-dessous à l'aide de la figure 2A.Therefore, the thermal engine of the device is not shown in Figures 2A, 2B, 2C, 3A, 3B and 3C describing the operation of this device in this electrical mode. However, the primary shaft 31 of such a heat engine is shown blocked in these figures, according to the invention, by means 60. These means may be, for example, electronically controlled clamping elements. As a result, the number of operating positions of the device is limited because one of the electrical machines can no longer transmit power through this shaft. primary, as described below using Figure 2A.

Sur cette figure 2A sont représentées une première machine électrique 32 à l'arrêt et une deuxième machine électrique 33 transmettant de la puissance via son arbre 39 à l'arbre 34 de la roue motrice 35.In this FIG. 2A there is shown a first electric machine 32 stopped and a second electric machine 33 transmitting power via its shaft 39 to the shaft 34 of the driving wheel 35.

De fait, un ensemble mécanique 3a, délimité par une ligne fermée en trait mixte, analogue à l'ensemble la déjà décrit relie l'arbre primaire 31, l'arbre de sortie 34 et les arbres 38 ou 39 des machines électriques 32 ou 33. De même, cet ensemble mécanique 3a comprend deux trains épicycloïdaux 43 et 44 comportant un porte-satellites commun 45 qui entraîne six axes (trois axes par train disposés à 120° les uns par rapport aux autres) dont uniquement quatre axes 46 à 49 sont représentés, et six satellites (trois satellites par train disposés à 120° les uns par rapport aux autres) dont uniquement quatre satellites 50a, 50b, 51a et 51b sont représentés.In fact, a mechanical assembly 3a delimited by a closed line in phantom, similar to the assembly already described, connects the primary shaft 31, the output shaft 34 and the shafts 38 or 39 of the electrical machines 32 or 33 Likewise, this mechanical assembly 3a comprises two planetary gear trains 43 and 44 comprising a common planet carrier 45 which drives six axes (three axes per train arranged at 120 ° relative to one another) of which only four axes 46 to 49 are shown, and six satellites (three satellites per train arranged at 120 ° relative to each other) of which only four satellites 50a, 50b, 51a and 51b are shown.

Un dispositif de commutation 58 permet de relier l'arbre 39 de la machine électrique 33 soit à une couronne 55, directement reliée à l'arbre de sortie 42, soit au planétaire 56 du train épicycloïdal 43 de l'ensemble 3a.A switching device 58 makes it possible to connect the shaft 39 of the electrical machine 33 to either a ring 55, directly connected to the output shaft 42, or to the sun gear 56 of the epicyclic gear train 43 of the assembly 3a.

A cet effet, ce dispositif de commutation 58 comprend des moyens tels qu'un crabot 58b pouvant s'engager ou se dégager vis-à-vis des pignons 58a ou 58c reliés respectivement à la couronne 55 ou au planétaire 43.For this purpose, this switching device 58 comprises means such as a dog 58b that can engage or disengage vis-à-vis the pinions 58a or 58c respectively connected to the ring 55 or the sun gear 43.

Ainsi, la machine 33 peut fonctionner selon deux modes :Thus, the machine 33 can operate in two modes:

- un premier mode tel que la machine électrique 33 fournit son couple à la roue 35 directement via cette couronne 55, ce mode étant ensuite dénommé mode 1.- A first mode such that the electric machine 33 provides its torque to the wheel 35 directly via the ring 55, this mode is then referred to as mode 1.

Dans les figures 2A, 2B et 2C, la machine électrique 33 est en position d'utilisation de ce mode 1.In FIGS. 2A, 2B and 2C, the electric machine 33 is in the use position of this mode 1.

C'est pourquoi, des éléments de transmission - pignon 58c, roue 58d et planétaire 56 - propres à un autre mode de transmission décrit ci-dessous sont représentés en pointillés sur ces figures 2A, 2B et 2C.Therefore, transmission elements - pinion 58c, 58d and planetary wheel 56 - specific to another mode of transmission described below are shown in dashed lines in these Figures 2A, 2B and 2C.

- un second mode tel que la machine électrique 33 fournit son couple à la roue 35 via le train épicycloïdal 43, ce mode étant ensuite dénommé mode 2.a second mode such as the electric machine 33 provides its torque to the wheel 35 via the planetary gear train 43, which mode is then referred to as mode 2.

Dans les figures 3A, 3B et 3C, la machine électrique 33 est en position d'utilisation de ce mode 2. C'est pourquoi, l'élément de transmission - pignon 58a- propre au mode 1 décrit ci-dessus est représenté en pointillés sur ces figures 3A, 3B et 3C.In FIGS. 3A, 3B and 3C, the electric machine 33 is in the use position of this mode 2. Therefore, the transmission element - pinion 58a specific to the mode 1 described above is shown in dashed lines. in these figures 3A, 3B and 3C.

Indépendamment du mode mis en œuvre pour la machine 33, cette dernière peut fournir toute la puissance motrice à l'arbre 34. Cette situation est représentée dans les figures 2A - machine 33 en mode 1 - et 3A - machine 33 en mode 2.Independently of the mode implemented for the machine 33, the latter can supply all the motive power to the shaft 34. This situation is represented in FIGS. 2A - machine 33 in mode 1 - and 3A - machine 33 in mode 2.

La machine 32 étant à l'arrêt, elle est représentée en pointillés comme les éléments de transmission qui lui sont associés, à savoir l'arbre 38, l'élément (roue) 52d et le planétaire 57.The machine 32 being stopped, it is represented in dashed lines as the transmission elements associated with it, namely the shaft 38, the element (wheel) 52d and the sun gear 57.

Cette machine électrique 32 peut également fournir toute la puissance à l'arbre 34 de roue 35 lorsque la machine électrique 33 est à l'arrêt, comme représenté sur les figures 2B - machine 33 en mode 1 - ou 3B - machine 33 en mode 2.This electric machine 32 can also provide all the power to the wheel shaft 35 when the electric machine 33 is stopped, as shown in FIG. 2B - machine 33 in mode 1 - or 3B - machine 33 in mode 2 .

Dans ce cas, les éléments de transmission - arbre 38, élément (roue) 52d et planétaire 57 - de la machine 32 sont représentés en trait plein tandis que les éléments de transmission de la machine 33 à l'arrêt sont représentés en pointillés.In this case, the transmission elements - shaft 38, element (wheel) 52d and planetary gear 57 - of the machine 32 are shown in solid line while the transmission elements of the machine 33 stopped are shown in dashed lines.

Finalement, comme montré sur les figures 2C - machine 33 en mode 1 - ou 3C - machine 33 en mode 2, les machines électriques 32 et 33 peuvent fournir conjointement de la puissance à l'arbre 34 de la roue motrice. Conformément à l'invention, l'arbre primaire 10 est représenté bloqué dans l'ensemble des positions décrites ci- dessus. Ainsi, aucune puissance n'est requise pour bloquer les rotations de cet arbre primaire pouvant provoquer un démarrage du moteur thermique. De plus, la machine 32 est maintenue dans un mode de fonctionnement unique qui lui permet de fournir une puissance de façon continue. La machine 33 peut ainsi modifier son mode de fonctionnement de façon continue en utilisant la machine 32 pour obtenir une puissance constante au niveau de l'arbre 34 de roue 35 pendant ces changements de mode. En définitive, la puissance fournie à la roue motrice peut être générée indifféremment par l'une ou l'autre des machines électriques 32 ou 33.Finally, as shown in FIG. 2C - machine 33 in mode 1 - or 3C - machine 33 in mode 2, the electric machines 32 and 33 can jointly supply power to shaft 34 of the driving wheel. According to the invention, the primary shaft 10 is shown locked in all the positions described above. Thus, no power is required to block the rotations of the primary shaft that can cause a start of the engine. In addition, the machine 32 is maintained in a unique operating mode that allows it to provide power continuously. The machine 33 can thus change its mode of operation continuously by using the machine 32 to obtain a constant power at the wheel shaft 34 during these mode changes. Ultimately, the power supplied to the driving wheel can be generated indifferently by one or the other of the electric machines 32 or 33.

De plus, il est possible lors du changement de mode de générer le couple fourni à la roue uniquement à l'aide de la machine électrique qui conserve la même position dans la cinématique de la transmission dans les deux modes - dans notre exemple, la machine électrique 32.In addition, it is possible when changing the mode to generate the torque supplied to the wheel only with the help of the electric machine which retains the same position in the kinematics of the transmission in both modes - in our example, the machine electric 32.

La désolidarisation puis la re-solidarisation de l'autre machine électrique - dans notre exemple, la machine électrique 33 - peut ainsi se faire de manière totalement transparente . The separation and the re-joining of the other electrical machine - in our example, the electric machine 33 - can be done in a completely transparent manner.
