Abstract
Description
L'invention concerne une chaîne de traction hybride différentielle pour un véhicule automobile. The invention relates to a differential hybrid traction chain for a motor vehicle.
L'invention concerne plus particulièrement une transmission pour un véhicule automobile comportant un premier et un second moteur, tels qu'un moteur thermique et un moteur électrique, reliés à un premier et à un second organe d'entrée d'un train épicycloïdal dont l'organe de sortie entraîne les roues motrices du véhicule. The invention relates more particularly to a transmission for a motor vehicle comprising a first and a second engine, such as a heat engine and an electric motor, connected to a first and to a second input member of a planetary gear train whose l The output member drives the drive wheels of the vehicle.
Les avantages des véhicules électriques sont connus et proviennent notamment du caractère silencieux et non polluant de leur moteur. The advantages of electric vehicles are known and come in particular from the silent and non-polluting nature of their engine.
Toutefois, un véhicule disposant seulement d'un moteur électrique est obligé de recharger régulièrement sa batterie d'accumulateur, ce qui impose une immobilisation totale du véhicule et suppose de plus que soient installées des bornes d'alimentation spécifiques. However, a vehicle having only an electric motor is obliged to regularly recharge its accumulator battery, which imposes total immobilization of the vehicle and also supposes that specific supply terminals are installed.
De plus, il est nécessaire d'effectuer un compromis entre la puissance du moteur électrique qui conditionne la vitesse maximale du véhicule d'une part et, d'autre part,
I'autonomie conférée par les batteries.In addition, it is necessary to make a compromise between the power of the electric motor which conditions the maximum speed of the vehicle on the one hand and, on the other hand,
The autonomy conferred by the batteries.
De la sorte, et en l'état actuel de la technique, les véhicules purement électriques présentent le double inconvénient d'avoir une faible autonomie et d'avoir de faibles performances. In this way, and in the current state of the art, purely electric vehicles have the double disadvantage of having a low range and of having poor performance.
C'est dans le but de proposer un véhicule très peu polluant et parfaitement autonome que sont actuellement développés les véhicules à motorisation hybride. It is with the aim of offering a very low-pollution and perfectly autonomous vehicle that hybrid motor vehicles are currently being developed.
En effet, le véhicule hybride peut circuler grâce à la seule énergie de son moteur électrique, notamment en circulation urbaine, pour peu qu'il soit muni d'une batterie d'accumulateurs lui conférant une autonomie et une puissance suffisantes pour les courts trajets effectués en milieu urbain. Indeed, the hybrid vehicle can circulate thanks to the only energy of its electric motor, in particular in urban circulation, provided that it is provided with a storage battery conferring on it a sufficient autonomy and power for the short journeys made. in an urban environment.
Dans le cas du moteur hybride, un moteur thermique complémentaire du moteur électrique est installé et permet soit d'apporter un complément de puissance pour des trajets sur route, soit de recharger les batteries d'accumulateur en utilisant le moteur électrique comme génératrice de courant. In the case of the hybrid engine, a thermal engine complementary to the electric motor is installed and makes it possible either to provide additional power for road journeys, or to recharge the accumulator batteries by using the electric motor as a current generator.
L'agencement particulier des organes composant la chaîne de traction hybride différentielle est particulièrement avantageux par rapport à celui d'une chaîne de traction hybride, dite "en série", dans laquelle un moteur thermique entraîne le rotor d'une génératrice de courant dont le courant est ensuite transmis au moteur électrique chargé de l'entraînement des roues motrices. The particular arrangement of the components of the differential hybrid traction chain is particularly advantageous compared to that of a hybrid traction chain, known as "in series", in which a heat engine drives the rotor of a current generator, the current is then transmitted to the electric motor responsible for driving the drive wheels.
Dans une chaîne de transmission hybride différentielle, on évite l'implantation d'une génératrice de courant, ce qui représente un gain de place et un gain de coût important. In a differential hybrid transmission chain, the installation of a current generator is avoided, which saves space and saves significant cost.
Ce type de transmission conserve toutefois l'avantage de ne pas nécessiter de boîte de vitesses puisqu'il est possible, par combinaison des vitesses de rotation du moteur thermique et du moteur électrique, d'obtenir une plage continue de vitesses en sortie de transmission. However, this type of transmission retains the advantage of not requiring a gearbox since it is possible, by combining the rotational speeds of the heat engine and the electric motor, to obtain a continuous range of speeds at the output of the transmission.
De plus, contrairement aux chaînes de traction hybride en série dans laquelle toute la puissance motrice du véhicule est fournie par le moteur électrique, la puissance motrice maximale d'une chaîne de traction hybride différentielle est fournie à la fois par le moteur électrique et par le moteur thermique, ce qui permet de réaliser des gains de poids, de place et de coût importants pour l'implantation dans un véhicule automobile. In addition, unlike hybrid powertrains in series in which all the driving power of the vehicle is supplied by the electric motor, the maximum driving power of a differential hybrid powertrain is supplied by both the electric motor and the heat engine, which allows significant weight, space and cost savings for installation in a motor vehicle.
L'invention a donc pour but de proposer une transmission pour une chaîne de traction hybride différentielle qui permette d'allier aux qualités inhérentes à cette conception des fonctionnalités supplémentaires visant à augmenter encore la souplesse d'utilisation et l'intérêt de l'intégration d'une telle chaîne de traction dans un véhicule automobile. The object of the invention is therefore to propose a transmission for a differential hybrid traction chain which makes it possible to combine the qualities inherent in this design with additional functionalities aimed at further increasing the flexibility of use and the advantage of integrating 'Such a traction chain in a motor vehicle.
Dans ce but, I'invention propose une transmission du type vu précédemment, caractérisée en ce qu'elle dispose d'un premier organe d'immobilisation assurant le blocage relatif des éléments du train en vue d'imposer un rapport des vitesses de rotation constant entre les deux moteurs. To this end, the invention proposes a transmission of the type seen above, characterized in that it has a first immobilizing member ensuring the relative blocking of the elements of the train with a view to imposing a constant speed ratio between the two motors.

Dans l'exemple de réalisation qui est représenté sur les figures, le premier moteur 14 est un moteur thermique et le second moteur est un moteur électrique. In the embodiment which is shown in the figures, the first motor 14 is a heat engine and the second motor is an electric motor.
La transmission 10 est destinée à entraîner en rotation deux arbres de sortie 20 reliés à des roues motrices du véhicule (non représentées). The transmission 10 is intended to drive in rotation two output shafts 20 connected to the driving wheels of the vehicle (not shown).
La transmission 10 est enfermée à l'intérieur d'un carter 22 et comporte tout d'abord un train épicycloïdal plan 24. The transmission 10 is enclosed inside a casing 22 and firstly comprises a planar planetary gear train 24.
Les arbres d'entrée 12, 16 sont agencés sur le même axe Al et sont guidés chacun dans un palier respectif 13, 17 du carter 22 de la transmission 10. The input shafts 12, 16 are arranged on the same axis A1 and are each guided in a respective bearing 13, 17 of the casing 22 of the transmission 10.
Le train épicycloïdal 24 est agencé axialement entre les deux paliers 13, 17 d'axe Al du carter 22 de la transmission 10. The planetary gear 24 is arranged axially between the two bearings 13, 17 of axis Al of the casing 22 of the transmission 10.

Comme on peut le voir sur les figures, le planétaire 26 forme un premier composant d'entrée de mouvement de la transmission 10, et il est entraîné en rotation autour de son axe Al par le premier arbre d'entrée 12, tandis que le portesatellites 30 forme un deuxième composant de sortie de mouvement, et il est entraîné en rotation autour du même axe Al par le second arbre d'entrée 16. As can be seen in the figures, the sun gear 26 forms a first movement input component of the transmission 10, and it is rotated about its axis A1 by the first input shaft 12, while the satellite carriers 30 forms a second movement output component, and it is rotated about the same axis A1 by the second input shaft 16.
La couronne dentée 32 comporte un manchon tubulaire 36 qui permet son montage à rotation sur l'arbre d'entrée 12 qui entraîne le planétaire 26. The ring gear 32 includes a tubular sleeve 36 which allows it to be mounted in rotation on the input shaft 12 which drives the planet wheel 26.
Afin de parfaire la rigidité du train épicycloïdal 24 et afin d'assurer une bonne coaxialité des arbres d'entrée 12, 16, le premier arbre 12 comporte une extrémité axiale 38 qui est guidée en rotation dans le porte-satellites 30 qui est solidaire du second arbre 16. In order to perfect the rigidity of the planetary gear train 24 and in order to ensure good coaxiality of the input shafts 12, 16, the first shaft 12 has an axial end 38 which is guided in rotation in the planet carrier 30 which is integral with the second tree 16.
Comme on peut le voir sur les figures, le mouvement des moteurs 14, 18 est récupéré en sortie du train épicycloïdal 24 grâce à une denture 40 formée sur le manchon 38 de la couronne 32 qui forme ainsi le troisième composant de sortie de mouvement du train 24. As can be seen in the figures, the movement of the motors 14, 18 is recovered at the outlet of the planetary gear train 24 thanks to a toothing 40 formed on the sleeve 38 of the crown 32 which thus forms the third component of the train movement output 24.
La denture 40 du manchon 38 attaque, par l'intermédiaire d'un pignon réducteur 42, une couronne externe 44 d'un différentiel à pignon conique 46 de conception connue qui permet de transmettre un couple moteur aux arbres de sortie 20 reliés chacun à une roue motrice du véhicule. The toothing 40 of the sleeve 38 attacks, by means of a reducing pinion 42, an outer ring 44 of a bevel gear differential 46 of known design which makes it possible to transmit a driving torque to the output shafts 20 each connected to a driving wheel of the vehicle.
Conformément aux enseignements de l'invention, la transmission 10 est munie d'organes d'immobilisation qui sont susceptibles de bloquer les mouvements relatifs de certains éléments de la transmission 10 dans le but d'obtenir différents modes de fonctionnement de la chaîne de traction hybride d ifférentielle . In accordance with the teachings of the invention, the transmission 10 is provided with immobilizing members which are capable of blocking the relative movements of certain elements of the transmission 10 in order to obtain different modes of operation of the hybrid powertrain differential.
La transmission 10 comporte notamment des moyens pour bloquer les mouvements relatifs du planétaire 26 par rapport au carter 22 ou par rapport à la couronne 32. The transmission 10 includes in particular means for blocking the relative movements of the sun gear 26 relative to the casing 22 or relative to the crown 32.
A cet effet, une roue à denture externe 50 est montée solidaire en rotation sur le premier arbre d'entrée 12 par l'intermédiaire de cannelures 48. To this end, an external toothed wheel 50 is mounted for rotation on the first input shaft 12 by means of grooves 48.
La roue dentée 50 est agencée axialement entre le palier 13 du carter 22 et le manchon 38 de la roue 32 qui comportent chacun respectivement une denture externe 52, 54 correspondante. The toothed wheel 50 is arranged axially between the bearing 13 of the casing 22 and the sleeve 38 of the wheel 32 which each have a corresponding external toothing 52, 54 respectively.
Un baladeur 56 est monté coulissant sur la roue dentée 50 du premier arbre d'entrée 12 et est susceptible de coulisser axialement, vers la gauche ou vers la droite en considérant les figures, de part et d'autre d'une position intermédiaire, représentée notamment sur les figures 1 et 2, dans laquelle le baladeur 26 ne coopère qu'avec la roue dentée 50. A walkman 56 is slidably mounted on the toothed wheel 50 of the first input shaft 12 and is capable of sliding axially, to the left or to the right considering the figures, on either side of an intermediate position, shown in particular in FIGS. 1 and 2, in which the player 26 only cooperates with the toothed wheel 50.
Le baladeur 56 est destiné ainsi à provoquer l'accouplement en rotation de la roue dentée 50 du premier arbre d'entrée 12 respectivement avec la denture externe 52 du palier 13 du carter 22 ou avec celle 54 du manchon 38 de la couronne 32. The player 56 is thus intended to cause the rotation of the toothed wheel 50 of the first input shaft 12 respectively with the external toothing 52 of the bearing 13 of the casing 22 or with that 54 of the sleeve 38 of the crown 32.
La transmission 10 comporte également un dispositif à crabot 58 susceptible de rendre solidaire en rotation le portesatellites 30, qui est solidaire du second arbre d'entrée 16, et le manchon 17 du carter 22 dans lequel est guidé le second arbre 16. The transmission 10 also includes a dog clutch 58 capable of making the satellite carriers 30 integral in rotation, which is integral with the second input shaft 16, and the sleeve 17 of the housing 22 in which the second shaft 16 is guided.
Le crabot 58 est monté coulissant sur une denture du manchon 17 et est destiné à coopérer avec une denture correspondante du porte-satellites 30. The dog clutch 58 is slidably mounted on a toothing of the sleeve 17 and is intended to cooperate with a corresponding toothing of the planet carrier 30.
Enfin, il est prévu un dispositif 60 qui permet de bloquer la rotation de la couronne 32 du train épicycloïdal 24, ce qui entraîne bien entendu le blocage des arbres de sortie 20 reliés aux roues motrices du véhicule. Finally, there is provided a device 60 which makes it possible to block the rotation of the crown 32 of the planetary gear 24, which of course results in the blocking of the output shafts 20 connected to the drive wheels of the vehicle.
Le dispositif 60 effectue un blocage indirect de la couronne 32 car il comporte un doigt rétractable 62 solidaire du carter 22, qui est susceptible de coopérer avec une roue dentée solidaire du boîtier du différentiel 46 à pignon conique. The device 60 performs an indirect blocking of the crown 32 because it comprises a retractable finger 62 secured to the casing 22, which is capable of cooperating with a toothed wheel secured to the housing of the differential 46 with bevel gear.
Les différents modes de fonctionnement de la chaîne de traction hybride selon l'invention vont être maintenant décrits en référence aux figures 2 à 6. The different operating modes of the hybrid traction chain according to the invention will now be described with reference to FIGS. 2 to 6.
On a représenté sur la figure 2 la chaîne de traction en mode de fonctionnement hybride différentiel. FIG. 2 shows the powertrain in differential hybrid operating mode.
Chacun des dispositifs de blocage 56, 58, 60 est alors désactivé de sorte que le moteur thermique 14 entraîne librement l'engrenage planétaire 26 et que le moteur électrique 18 entraîne librement le porte-satellites 30. Each of the blocking devices 56, 58, 60 is then deactivated so that the heat engine 14 freely drives the planetary gear 26 and the electric motor 18 freely drives the planet carrier 30.
Notamment, le baladeur 56 est en position intermédiaire. In particular, the player 56 is in the intermediate position.
De la sorte, la couronne 32 du train épicycloïdal 24, qui est libre en rotation par rapport au carter 22, est animée d'un mouvement de rotation dont la vitesse est une composition linéaire des vitesses de l'engrenage planétaire 26 et du portesatellites 30, pondérées chacune en fonction des rapports de transmission déterminés par les diamètres respectifs du planétaire 26, des satellites 28 et de la denture interne de la couronne 32. In this way, the crown 32 of the planetary gear train 24, which is free to rotate relative to the casing 22, is driven in a rotational movement whose speed is a linear composition of the speeds of the planetary gear 26 and the satellite carriers 30 , each weighted according to the transmission ratios determined by the respective diameters of the sun gear 26, the satellites 28 and the internal toothing of the crown 32.
Dans ce mode de fonctionnement, il est particulièrement intéressant d'utiliser le moteur thermique à un régime constant qui correspond à son régime de rotation pour lequel son rendement est optimal. Le moteur électrique 18 est alors commandé pour adapter la vitesse de la couronne 32 afin d'adapter la vitesse du véhicule à la valeur voulue par le conducteur. In this operating mode, it is particularly advantageous to use the heat engine at a constant speed which corresponds to its rotation speed for which its performance is optimal. The electric motor 18 is then controlled to adapt the speed of the crown 32 in order to adapt the speed of the vehicle to the value desired by the driver.
On a représenté sur la figure 3 la chaîne de traction hybride en mode de traction électrique pure. FIG. 3 shows the hybrid traction chain in pure electric traction mode.
Dans ce mode de fonctionnement, le baladeur 56 est déplacé axialement vers la gauche, en considérant les figures, de manière à réaliser l'accouplement en rotation entre la roue dentée 50 du premier arbre d'entrée 12 et le palier 13 du carter 22, ce qui a pour conséquence d'immobiliser le premier arbre d'entrée 12. In this operating mode, the player 56 is moved axially to the left, considering the figures, so as to produce the coupling in rotation between the toothed wheel 50 of the first input shaft 12 and the bearing 13 of the casing 22, which has the consequence of immobilizing the first input shaft 12.
On neutralise ainsi le moteur thermique 14 et l'engrenage planétaire 26 est également bloqué. The thermal engine 14 is thus neutralized and the planetary gear 26 is also blocked.
De la sorte, la vitesse de rotation de la couronne 32 du train épicycloïdal 24 est directement commandée par le moteur électrique 18 qui l'entraîne en rotation par l'intermédiaire du porte-satellites 30. In this way, the speed of rotation of the crown 32 of the planetary gear 24 is directly controlled by the electric motor 18 which drives it in rotation via the planet carrier 30.
Ce mode de fonctionnement est par exemple préféré en cas de circulation du véhicule en milieu urbain en raison de son silence et de son caractère non polluant, d'autant plus que les performances nécessaires à un tel type de circulation sont largement assurées par le seul moteur électrique 18. This operating mode is for example preferred in the event of vehicle traffic in an urban environment because of its silence and its non-polluting nature, all the more since the performance required for such a type of traffic is largely ensured by the engine alone. electric 18.
On a représenté sur la figure 4 la chaîne de traction hybride en mode de fonctionnement hybride parallèle. FIG. 4 shows the hybrid powertrain in parallel hybrid operating mode.
Dans ce mode de fonctionnement, le baladeur 56 est déplacé axialement vers la droite, en considérant la figure, de manière à accoupler en rotation la roue dentée 50 du premier arbre d'entrée 12 avec le manchon 38 de la couronne 32. In this operating mode, the player 56 is moved axially to the right, considering the figure, so as to rotate the toothed wheel 50 of the first input shaft 12 with the sleeve 38 of the crown 32.
Ceci a pour conséquence de "bloquer" le train épicycloïdal 24, c'est-à-dire que l'engrenage planétaire 26, les satellites 28, le porte-satellites 30 et la couronne 32 sont immobiles les uns par rapport aux autres et sont susceptibles de tourner à la même vitesse autour de l'axe Al. This has the effect of "blocking" the planetary gear 24, that is to say that the planetary gear 26, the satellites 28, the planet carrier 30 and the ring 32 are stationary with respect to each other and are likely to rotate at the same speed around the axis Al.
Dans ce mode de fonctionnement, les deux moteurs 14, 18 fonctionnent simultanément et à la même vitesse pour entraîner en rotation l'ensemble du train épicycloïdal 24. In this operating mode, the two motors 14, 18 operate simultaneously and at the same speed to rotate the whole planetary gear train 24.
On peut également choisir de ne pas alimenter le moteur électrique 18 et de n'utiliser que le seul moteur thermique 14 pour entraîner le véhicule, ou choisir d'utiliser une partie de l'énergie fournie par le moteur thermique 14 pour produire du courant électrique grâce au moteur électrique 18 utilisé comme génératrice afin de recharger des accumulateurs tout en roulant. It is also possible to choose not to power the electric motor 18 and to use only the heat engine 14 to drive the vehicle, or to choose to use part of the energy supplied by the heat engine 14 to produce electric current. thanks to the electric motor 18 used as a generator in order to recharge accumulators while driving.
On a représenté sur la figure 5 un mode particulier de fonctionnement de la chaîne de traction hybride dans laquelle le doigt rétractable 62 du dispositif de blocage 60 immobilise le boîtier de différentiel 46 et par conséquent la couronne 32 du train épicycloïdal 24. FIG. 5 shows a particular mode of operation of the hybrid traction chain in which the retractable finger 62 of the locking device 60 immobilizes the differential housing 46 and consequently the crown 32 of the planetary gear 24.
Bien entendu, ce mode de fonctionnement implique que le véhicule est à l'arrêt. Of course, this operating mode implies that the vehicle is stationary.
La couronne 32 étant immobile en rotation, il subsiste toutefois la possibilité pour l'engrenage planétaire 26 et pour porte-satellites 30 d'être entraînés en rotation l'un par l'autre. The crown 32 being stationary in rotation, there remains however the possibility for the planetary gear 26 and for planet carrier 30 to be driven in rotation by one another.
II est alors possible, dans un premier cas, de provoquer la mise en rotation du moteur thermique 14, en vue de son démarrage, à l'aide du moteur électrique 18, ce qui est particulièrement avantageux car cela évite ainsi l'implantation d'un démarreur complémentaire. It is then possible, in a first case, to cause the combustion engine 14 to rotate, with a view to starting it, using the electric motor 18, which is particularly advantageous since this thus avoids the establishment of a complementary starter.
Dans un second cas, on peut utiliser le moteur thermique 14 pour entraîner en rotation le moteur électrique 18 qui, utilisé comme une génératrice de courant, va permettre de recharger les batteries d'accumulateur du véhicule. In a second case, the heat engine 14 can be used to rotate the electric motor 18 which, used as a current generator, will allow the vehicle's accumulator batteries to be recharged.
Enfin, on a représenté sur la figure 6 la chaîne de traction hybride en mode de traction thermique pure. Finally, FIG. 6 shows the hybrid traction chain in pure thermal traction mode.
Dans ce mode de fonctionnement, le baladeur 58 est commandé pour être déplacé, axialement vers la gauche en considérant la figure, de manière à provoquer l'accouplement en rotation du porte-satellites 30 avec le manchon 17 du carter 22. In this operating mode, the player 58 is controlled to be moved, axially to the left, considering the figure, so as to cause the planet carrier 30 to rotate in coupling with the sleeve 17 of the housing 22.
Dans ce mode de fonctionnement, le moteur électrique 18 est ainsi neutralisé et le porte-satellites 30 est bloqué en rotation. In this operating mode, the electric motor 18 is thus neutralized and the planet carrier 30 is locked in rotation.
De la sorte, la vitesse de rotation de la couronne 32 du train épicycloïdal 24 est commandée par la vitesse de rotation de l'engrenage planétaire 26, et donc par le moteur thermique 14, le rapport de démultiplication étant une fonction des diamètres respectifs des composants du train épicycloïdal 24. In this way, the speed of rotation of the crown 32 of the planetary gear train 24 is controlled by the speed of rotation of the planetary gear 26, and therefore by the heat engine 14, the gear ratio being a function of the respective diameters of the components. of the planetary gear train 24.
II est à noter que dans ce mode de fonctionnement,
I'engrenage planétaire 26 et la couronne 32 tournent en sens inverse autour de l'axe Al. It should be noted that in this operating mode,
The planetary gear 26 and the crown 32 rotate in opposite directions around the axis Al.
Ce mode de fonctionnement peut ainsi former une marche arrière pour le véhicule, sauf à utiliser un mécanisme inverseur permettant de rétablir une marche avant. This operating mode can thus form a reverse gear for the vehicle, except by using a reversing mechanism making it possible to restore forward gear.
On a représenté sur la figure 7 une variante de réalisation de l'invention dans laquelle la couronne 32 et le porte-satellites 30 ont été intervertis de manière à former respectivement le deuxième composant d'entrée de mouvement et le troisième composant de sortie de mouvement du train épicycloïdal 24. FIG. 7 shows an alternative embodiment of the invention in which the ring gear 32 and the planet carrier 30 have been inverted so as to respectively form the second motion input component and the third motion output component of the planetary gear train 24.
Ce mode de réalisation permet de réaliser, tout comme celui vu précédemment, une chaîne de traction hybride ou parallèle, seul le rapport des vitesses des deux moteurs, entre eux et avec les roues motrices, étant modifié. II permet aussi d'entraîner l'un des moteurs 14, 18 à l'aide de l'autre. This embodiment makes it possible, like the one seen above, to produce a hybrid or parallel traction chain, only the speed ratio of the two motors, between them and with the drive wheels, being modified. It also makes it possible to drive one of the motors 14, 18 using the other.
Toutefois, il existe une différence de fonctionnement entre les deux modes de réalisation dans le cas de blocage du deuxième composant d'entrée de mouvement, ce qui est représenté respectivement aux figures 6 et 7. However, there is a difference in operation between the two embodiments in the case of blockage of the second motion input component, which is shown in Figures 6 and 7 respectively.
En effet, comme on peut le voir sur la figure 7, le baladeur 58 est commandé pour être déplacé, axialement vers la gauche en considérant la figure, de manière à provoquer, dans ce cas, I'accouplement en rotation de la couronne 32 avec le manchon 17 du carter 22. Indeed, as can be seen in Figure 7, the player 58 is controlled to be moved, axially to the left considering the figure, so as to cause, in this case, the coupling in rotation of the crown 32 with the sleeve 17 of the housing 22.
On obtient ainsi l'entraînement en rotation des roues motrices à l'aide du seul moteur thermique 14, cette fois dans le même sens de rotation mais avec un rapport de réduction suffisamment important pour compenser l'absence de puissance fournie par le moteur électrique. The drive wheels are thus driven in rotation using the sole heat engine 14, this time in the same direction of rotation but with a reduction ratio sufficiently large to compensate for the lack of power supplied by the electric motor.
Dans les modes de réalisation de l'invention qui sont représentés sur les figures, les organes d'immobilisation 56, 58, 60 sont du type à crabot ou à doigt rétractable et représentent des moyen de réalisation simple de l'invention. In the embodiments of the invention which are shown in the figures, the immobilizing members 56, 58, 60 are of the dog clutch or retractable finger type and represent simple means of carrying out the invention.
Toutefois, il peut être intéressant de remplacer au moins l'un de ces organes d'immobilisation par des systèmes à friction, tels que ceux utilisés dans les boîtes de vitesses automatiques, qui permettent un fonctionnement sans à-coups lors des passages entre les différents modes de fonctionnement de la transmission 10 et qui permettent de s'affranchir de tout problème de synchronisation au moment de l'enclenchement des dispositifs d'immobilisation. However, it may be advantageous to replace at least one of these immobilizing members with friction systems, such as those used in automatic gearboxes, which allow smooth operation during the passages between the different operating modes of the transmission 10 and which make it possible to overcome any synchronization problem when the immobilization devices are engaged.
Les modes de réalisation de la chaîne de traction hybride qui sont représentés sur les figures sont susceptibles d'être modifiés sans sortir du cadre de l'invention. The embodiments of the hybrid traction chain which are shown in the figures are capable of being modified without departing from the scope of the invention.
II est par exemple possible d'intervertir les moteurs thermique 14 et électrique 18, en fonction de la prépondérance que l'on souhaite accorder à l'un ou à l'autre, pour modifier les rapports de démultiplications appliqués à l'un et à l'autre. It is for example possible to reverse the thermal 14 and electric 18 motors, depending on the preponderance which one wishes to grant to one or the other, to modify the gear ratios applied to one and to the other.
De même, on peut choisir de prévoir de bloquer la rotation du porte-satellites 30 par rapport au planétaire 26 ou à la couronne 32, plutôt que celle du planétaire 26 par rapport à la couronne 32, dans le but de bloquer le train épicycloïdal 24 pour que la chaîne de traction fonctionne en mode hybride parallèle. Likewise, it is possible to choose to provide for blocking the rotation of the planet carrier 30 relative to the sun gear 26 or to the crown 32, rather than that of the sun gear 26 relative to the crown 32, in order to block the planetary gear 24 so that the drive train operates in parallel hybrid mode.
