Description

DISPOSITIF DE TRACTION HYBRIDE DE VEHICULE AUTOMOBILE A DOUBLE CHEMIN DE PUISSANCE ELECTRIQUEELECTRIC POWER DUAL PATH MOTOR VEHICLE HYBRID TRACTION DEVICE

L’invention concerne un dispositif de traction hybride pour véhicule automobile comportant un moteur thermique avec sa boîte de vitesses manuelle ou robotisée, et une machine électrique connectée à la boîte de vitesses.The invention relates to a hybrid traction device for a motor vehicle comprising a heat engine with its manual or robotized gearbox, and an electric machine connected to the gearbox.

Plus précisément, elle a pour objet un dispositif de traction hybride à double chemin de puissance entre une machine électrique et les roues d’un véhicule, composé d’une boîte de vitesses à arbres parallèles, dont un arbre primaire qui transmet la puissance d’un moteur thermique d’entraînement à un arbre secondaire relié aux roues du véhicule, et d’une machine électrique.More specifically, it relates to a hybrid traction device with a dual power path between an electric machine and the wheels of a vehicle, consisting of a gearbox with parallel shafts, including a primary shaft which transmits the power to a heat engine driving a secondary shaft connected to the wheels of the vehicle, and an electric machine.

Dans les véhicules hybrides comportant une double motorisation, thermique et électrique, la machine électrique est parfois liée au moteur thermique sur sa face dite « accessoires », comme l’alternateur. Pour augmenter la puissance électrique installée et l’efficacité des échanges d’énergie de stockage en batterie et de restitution, il est plus avantageux de connecter la machine électrique à la boîte de vitesses. Cette disposition permet d’ouvrir ces véhicules à des possibilités nouvelles, en particulier le roulage en mode électrique, et de réduire leur consommation.In hybrid vehicles with dual motorization, internal combustion and electric, the electric machine is sometimes linked to the internal combustion engine on its so-called "accessory" side, such as the alternator. To increase the installed electric power and the efficiency of battery storage and restitution energy exchanges, it is more advantageous to connect the electric machine to the gearbox. This arrangement makes it possible to open up these vehicles to new possibilities, in particular driving in electric mode, and to reduce their consumption.

La publication DE 10 2016 120 010, décrit un groupe motopropulseur comportant un moteur thermique, une boîte de vitesses, et une machine électrique agencée à l’intérieur de la boîte, dans une disposition dite «add-in». L’arbre du rotor de la machine électrique porte un premier pignon, qui met en mouvement un premier arbre comportant deux pignons fixes, à l’aide d’un pignon intermédiaire. Un deuxième arbre porte deux pignons fous, un groupe de crabotage, et possède à son extrémité un pignon fixe qui engrène avec la couronne du différentiel. Une seconde boîte à deux rapports dédiés à la machine électrique, est ainsi adossée à la boîte de vitesses principale, qui est dédiée au moteur thermique.Publication DE 10 2016 120 010 describes a powertrain comprising a heat engine, a gearbox, and an electric machine arranged inside the box, in a so-called “ add-in ” arrangement. The rotor shaft of the electric machine carries a first pinion, which sets in motion a first shaft comprising two fixed pinions, with the aid of an intermediate pinion. A second shaft carries two idler gears, a dog clutch unit, and has a fixed gear at its end which meshes with the crown of the differential. A second two-speed gearbox dedicated to the electric machine is thus attached to the main gearbox, which is dedicated to the heat engine.

Dans un groupe motopropulseur hybride, la machine électrique peut être connectée à l’un ou à l’autre des arbres de la boîte de vitesses, ou aux deux, comme dans publication FR 2 787 395. Celle-ci décrit une transmission hybride, dans laquelle la machine électrique est agencée entre le moteur et la boîte de vitesses. La machine électrique se connecte par un crabot, soit à l’arbre primaire, soit à l’arbre secondaire de la boîte.In a hybrid powertrain, the electric machine can be connected to either or both of the gearbox shafts, as in publication FR 2 787 395. This describes a hybrid transmission, in which the electrical machine is arranged between the engine and the gearbox. The electric machine is connected by a dog clutch, either to the primary shaft or to the secondary shaft of the gearbox.

La connexion de la machine électrique à l’arbre primaire, présente certains avantages. On dispose en particulier d’une capacité de démarrage du moteur thermique, lorsque le véhicule est à l’arrêt. De plus, on peut associer à cette hybridation légère, un alterno-démarreur agencé sur la face «accessoires», qui assure le démarrage du moteur, dans presque toutes les situations, sauf par grand froid, où la courroie peut ne pas être assez efficiente.The connection of the electric machine to the primary shaft has certain advantages. In particular, there is a capacity for starting the heat engine, when the vehicle is stationary. In addition, this light hybridization can be associated with an alternator-starter arranged on the " accessories " side, which ensures engine starting in almost all situations, except in very cold weather, where the belt may not be efficient enough. .

Lorsque la machine électrique est liée avec l’arbre primaire, elle bénéficie des rapports de réduction de la boîte, et donne tout son potentiel de traction et de brio. Toutefois, elle perturbe l’inertie, et augmente la traînée équivalente de la boîte. Dans une boîte à commande manuelle, il faut donc découpler rapidement la machine électrique, avant la phase de synchronisation du rapport en cours d’engagement. Dans le cas d’une boîte robotisée, ce découplage n’est pas indispensable, car un superviseur pilote la machine électrique pendant les changements de rapport, de manière à limiter ou à supprimer, les effets indésirables d’inertie et de traînée. Dans certains cas, la machine électrique peut réaliser à elle seule la synchronisation. Les synchroniseurs classiques sont alors supprimés. Toutefois, pour une plus grande rapidité d’exécution, il est préférable d’ajouter un système de découplage de la machine électrique.When the electric machine is linked with the primary shaft, it benefits from the gearbox's reduction ratios, and gives all its traction and brilliance potential. However, it disturbs the inertia, and increases the equivalent drag of the box. In a manual gearbox, the electric machine must therefore be uncoupled quickly, before the synchronization phase of the gear being engaged. In the case of a robotic gearbox, this decoupling is not essential, because a supervisor controls the electric machine during gear changes, so as to limit or eliminate the undesirable effects of inertia and drag. In some cases, the electric machine can perform the synchronization on its own. The classic synchronizers are then removed. However, for greater speed of execution, it is preferable to add a system for decoupling the electric machine.

Par ailleurs, si la machine électrique est coaxiale à l’arbre primaire, l’absence de démultiplication lui permet difficilement d’assurer le démarrage du moteur thermique.Furthermore, if the electric machine is coaxial with the primary shaft, the absence of gear reduction makes it difficult for it to start the heat engine.

La présente invention vise à introduire une démultiplication entre la machine électrique et l’arbre primaire de la boîte, tout en pouvant la coupler sélectivement avec l’arbre primaire, ou avec l’arbre secondaire.The present invention aims to introduce a reduction between the electric machine and the primary shaft of the gearbox, while being able to couple it selectively with the primary shaft, or with the secondary shaft.

Dans ce but, elle propose que la machine électrique transmette sa puissance sur un rapport unique à un arbre de couplage avec la boîte, puis à partir de celui-ci, sélectivement sur l’arbre primaire, ou sur l’arbre secondaire de la boîte.For this purpose, it proposes that the electric machine transmits its power on a single ratio to a coupling shaft with the box, then from this, selectively on the primary shaft, or on the secondary shaft of the box. .

Dans un mode de réalisation particulier, l’arbre de couplage porte deux pignons fous, transmettant respectivement la puissance de la machine électrique vers l’arbre primaire, et vers l’arbre secondaire.In a particular embodiment, the coupling shaft carries two idler gears, respectively transmitting the power of the electric machine to the primary shaft, and to the secondary shaft.

Dans ce cas, l’arbre de couplage porte avantageusement un dispositif de couplage, pour chacun de ces deux pignons fous.In this case, the coupling shaft advantageously carries a coupling device, for each of these two idler gears.

La présente invention sera mieux comprise à la lecture de la description suivante d’un mode de réalisation non limitatif de celle-ci, en se reportant aux dessins annexés.The present invention will be better understood on reading the following description of a non-limiting embodiment thereof, with reference to the accompanying drawings.

Sur la figure 1, on a représenté en coupe longitudinale, un mode de réalisation du dispositif de traction hybride pour véhicule automobile 1, faisant l’objet de l’invention. Ce dispositif est composé essentiellement d’une boîte de vitesses à arbres parallèles 20, 30, dont un arbre primaire 20 transmet la puissance d’un moteur thermique d’entraînement à un arbre secondaire 30 relié aux roues du véhicule, et d’une machine électrique 60, qui transmet sa puissance sur un rapport unique à un arbre de couplage 80 portant deux pignons fous 82, 83, puis à partir de celui-ci, sélectivement sur l’arbre primaire, ou sur l’arbre secondaire de la boîte.In Figure 1, there is shown in longitudinal section, an embodiment of the hybrid traction device for motor vehicle 1, which is the subject of the invention. This device is essentially composed of a gearbox with parallel shafts 20, 30, of which a primary shaft 20 transmits the power of a thermal drive motor to a secondary shaft 30 connected to the wheels of the vehicle, and of a machine electric 60, which transmits its power on a single report to a coupling shaft 80 carrying two idler gears 82, 83, then from the latter, selectively on the primary shaft, or on the secondary shaft of the box.

L’arbre de couplage 80 porte deux pignons fous 82, 83, transmettant respectivement la puissance de la machine électrique vers l’arbre primaire 20, et vers l’arbre secondaire 30. Le dispositif de traction hybride comporte un premier dispositif de couplage 90 assurant le couplage, du premier pignon fou 82 avec un pignon fixe 21 de l’arbre primaire, et un deuxième dispositif de couplage 97 assurant le couplage du deuxième pignon fou 83 avec un pignon fixe 31 de l’arbre secondaire 30, par l’intermédiaire d’un pignon fou 22 porté par l’arbre primaire 20.The coupling shaft 80 carries two idler gears 82, 83, respectively transmitting the power of the electric machine to the primary shaft 20, and to the secondary shaft 30. The hybrid traction device comprises a first coupling device 90 ensuring the coupling, of the first idler gear 82 with a fixed gear 21 of the primary shaft, and a second coupling device 97 ensuring the coupling of the second idler gear 83 with a fixed gear 31 of the secondary shaft 30, via an idler gear 22 carried by the primary shaft 20.

Grâce au premier dispositif de couplage 90, la puissance de la machine électrique passe du premier pignon fou 82 à un pignon fixe 21 de l’arbre primaire 20 de la boîte 1.Thanks to the first coupling device 90, the power of the electric machine passes from the first idler gear 82 to a fixed gear 21 of the primary shaft 20 of the gearbox 1.

Grâce au deuxième dispositif de couplage 97, elle passe du deuxième pignon fou 83, à un pignon fixe 31 de l’arbre secondaire 30 par l’intermédiaire d’un pignon fou 22 porté par l’arbre primaire. Les deux dispositifs de couplage sont commandés par le même actionneur 100, qui agit sur un axe commun 95 portant deux fourchettes de commande. Lorsque l’axe 95 se déplace dans un premier sens, le dispositif de couplage vers l’arbre primaire est verrouillé, et le dispositif de couplage vers l’arbre secondaire est ouvert. En se déplaçant dans l’autre sens, le dispositif de couplage vers l’arbre primaire est ouvert, et le dispositif de couplage vers l’arbre secondaire est verrouillé. Enfin dans une position centrale, les deux dispositifs de couplage sont ouverts.Thanks to the second coupling device 97, it passes from the second idler gear 83 to a fixed gear 31 of the secondary shaft 30 via an idler gear 22 carried by the primary shaft. The two coupling devices are controlled by the same actuator 100, which acts on a common axis 95 carrying two control forks. When axis 95 moves in a first direction, the coupling device to the primary shaft is locked, and the coupling device to the secondary shaft is open. Moving in the other direction, the coupling device to the primary shaft is open, and the coupling device to the secondary shaft is locked. Finally in a central position, the two coupling devices are open.

Le dispositif proposé, constitue un dispositif d’hybridation électrique ou de traction hybride complet. Ce dispositif est une extension d’une boîte de vitesses mécanique classique à arbres parallèles. Dans l’exemple de réalisation non limitatif illustré par les figures, c’est une boîte de vitesses manuelle. Elle peut aussi être équipée d’un embrayage automatisé, ou même être entièrement robotisée. Sans sortir du cadre de l’invention, le dispositif peut aussi être réalisé avec une transmission automatique, notamment à double embrayage.The proposed device constitutes a complete electric hybridization or hybrid traction device. This device is an extension of a classic mechanical gearbox with parallel shafts. In the non-limiting embodiment illustrated by the figures, it is a manual gearbox. It can also be equipped with an automated clutch, or even be fully robotized. Without departing from the scope of the invention, the device can also be produced with an automatic transmission, in particular with a double clutch.

La boîte de vitesses à laquelle on vient rapporter un module d’électrification est composée de deux carters, le carter d’embrayage 10 et le carter de mécanisme 11. A l’intérieur des carters 10, 11, on trouve l’arbre primaire 20, un arbre secondaire 30, un différentiel complet 40, un dispositif de changements de rapports composé de leviers de sélection et passage 50 agencés en extérieur de la boite, et de moyen de commande des fourchettes 52 reliés par un axe de commande 51 traversant la boîte de vitesses.The gearbox to which an electrification module has just been added is made up of two casings, the clutch casing 10 and the mechanism casing 11. Inside the casings 10, 11, there is the primary shaft 20 , a secondary shaft 30, a complete differential 40, a gear change device composed of selection and passage levers 50 arranged outside the box, and fork control means 52 connected by a control shaft 51 passing through the box of speeds.

L’hybridation, ou l’électrification de la boîte, consiste à rapporter à l’extérieur de celle-ci une machine électrique 60, dont le rotor entraine le manchon cannelé 61. L’arbre rotor de la machine électrique 60 entraine une descente de pignons commune vers l’arbre de couplage 80. L’arbre rotor de la machine électrique, entraîne d’abord l’arbre d’entrée 70 supportant une seule denture fixe, puis le pignon 71 solidaire du pignon 72 supporté par l’axe 73, qui à son tour entraine l’arbre de couplage 80 par sa denture fixe 81. Le mécanisme d’entraînement commun aux deux chemins de puissance, comprend au moins un arbre intermédiaire de renvoi 73 entre l’arbre de la machine électrique et l’arbre de couplage 80.The hybridization, or the electrification of the box, consists in bringing an electric machine 60 outside of it, the rotor of which drives the splined sleeve 61. The rotor shaft of the electric machine 60 causes a lowering of common pinions towards the coupling shaft 80. The rotor shaft of the electric machine first drives the input shaft 70 supporting a single fixed toothing, then the pinion 71 integral with the pinion 72 supported by the axis 73 , which in turn drives the coupling shaft 80 by its fixed toothing 81. The drive mechanism common to the two power paths, comprises at least one intermediate countershaft 73 between the shaft of the electric machine and the coupling shaft 80.

De l’arbre de couplage 80 au différentiel 40, deux chemins de puissance sont possibles.From coupling shaft 80 to differential 40, two power paths are possible.

Le premier chemin de puissance relie l’arbre 80 à l’arbre primaire 20 par le moyen de couplage 90 d’un premier pignon fou 82 en engrènement permanent avec un pignon fixe 21 de l’arbre primaire 20. Le premier pignon fou 82 engrène de manière permanente avec le plus grand pignon fixe 21 de l’arbre primaire. De préférence, le premier dispositif de couplage 90 est un dispositif sans crabotage.The first power path connects the shaft 80 to the primary shaft 20 by means 90 of coupling a first idler gear 82 in permanent mesh with a fixed gear 21 of the primary shaft 20. The first idler gear 82 meshes permanently with the largest fixed gear 21 of the primary shaft. Preferably, the first coupling device 90 is a device without dog clutch.

Selon ce premier chemin (voir figure 4) , la transmission de puissance de la machine électrique aux roues, est assurée, de la même manière que pour le moteur thermique, c’est-à-dire par tout ou partie des rapports de la boîte de vitesses. Pour les changements de rapports, le découplage de la machine électrique 60 est nécessaire. Son inertie est trop génératrice d’énergie pour les synchroniseurs normaux d’une boîte de vitesses. Les systèmes sans crabots, du type embrayage, sont plus rapides à ouvrir que les coupleurs à crabots. De nombreux systèmes d’embrayage sont capables en principe, d’assurer le découplage de la machine électrique, notamment des systèmes à commande hydraulique. Toutefois, leur intégration dans une boîte de vitesses manuelle, dépourvue à l’origine de système à pression hydraulique, génère un surcoût important. De plus, les embrayages hydrauliques sont actifs en permanence, si bien qu’ils dégradent sensiblement le rendement mécanique de la transmission.According to this first path (see Figure 4), the transmission of power from the electric machine to the wheels is ensured, in the same way as for the heat engine, that is to say by all or part of the gear ratios of speeds. For the gear changes, the decoupling of the electric machine 60 is necessary. Its inertia generates too much energy for the normal synchronizers of a gearbox. Systems without dogs, of the clutch type, are quicker to open than couplers with dogs. Many clutch systems are able, in principle, to ensure the decoupling of the electric machine, in particular hydraulically controlled systems. However, their integration into a manual gearbox, originally devoid of a hydraulic pressure system, generates a significant additional cost. In addition, the hydraulic clutches are permanently active, so that they significantly degrade the mechanical efficiency of the transmission.

Sans sortir du cadre de l’invention, différents types de dispositifs de couplage peuvent être utilisés. Dans un mode de réalisation non limitatif, le dispositif de couplage 90 est un coupleur conique auto-assisté, notamment du type décrit dans la publication FR 2 890 426. Il s’agit d’un système de couplage électromécanique à cônes équipés de rampes d’auto-assistance. Il est capable de développer le couple transmissible requis, et ne nécessite qu’une faible poussée axiale. Son actionneur est stable dans toute ses positions. Il ne dépense de l’énergie que lors les manœuvres. Enfin, ce système de couplage est suffisamment capacitif en dissipation d’énergie, pour rendre possible le couplage d’une machine électrique, avec un écart de régimes important.Without departing from the scope of the invention, different types of coupling devices can be used. In one non-limiting embodiment, the coupling device 90 is a self-assisted conical coupler, in particular of the type described in the publication FR 2 890 426. This is an electromechanical coupling system with cones equipped with damper ramps. self-help. It is able to develop the required transmissible torque, and requires only low axial thrust. Its actuator is stable in all its positions. It only expends energy when maneuvering. Finally, this coupling system is sufficiently capacitive in energy dissipation, to make possible the coupling of an electrical machine, with a significant difference in speeds.

Le coupleur conique 90 illustré par la figure 3 est composé d’un flasque 91 rapporté sur le pignon fou 82, entraînant en rotation un cône inférieur 92,a et un cône intermédiaire supérieur 92,b , et d’un cône supérieur 92,d solidaire d’un moyeu 94 fixés sur l’arbre de couplage 80, entraînant aussi en rotation un cône intermédiaire inférieur 92,c.The conical coupler 90 illustrated by FIG. 3 is composed of a flange 91 attached to the idler gear 82, rotating a lower cone 92,a and an upper intermediate cone 92,b, and an upper cone 92,d integral with a hub 94 fixed on the coupling shaft 80, also rotating a lower intermediate cone 92,c.

Le flasque 91 est par exemple en tôle, et rapporté sur le pignon fou 82, par soudure ou par un autre moyen. Ce flasque entraîne en rotation un premier cône inférieur 92,a et le second cône intermédiaire supérieur 92,b, grâce aux crans 91,a dans sa périphérie extérieure. Le cône intermédiaire inférieur 92,c, est solidaire en rotation avec le moyeu 94, par une cannelure dans sa périphérie intérieure. Enfin le cône supérieur 92,d est également solidaire du moyeu par l’intermédiaire de dents.The flange 91 is for example made of sheet metal, and attached to the idler gear 82, by welding or by another means. This flange rotates a first lower cone 92, a and the second upper intermediate cone 92, b, thanks to the notches 91, a in its outer periphery. The lower intermediate cone 92, c, is integral in rotation with the hub 94, by a groove in its inner periphery. Finally, the upper cone 92,d is also secured to the hub by means of teeth.

Ce coupleur est auto-assisté, car le couple de glissement et d’adhérence amplifie le serrage et la pression sur les faces de frottement. Le contact des dents du cône supérieur 92,d avec le moyeu 94 est oblique, de sorte que le couple de frottement crée une force axiale induite de serrage des cônes les uns sur les autres. Le couple de frottement des dents du cône supérieur 92,d sur le moyeu 94, crée une force axiale induite de serrage des cônes 92,d ,92,c ,9,b et 92,a les uns sur les autres, en phase de synchronisation ou d’adhérence pendant la phase couplée. La force de serrage des cônes s’ajoute à celle fournie par l’actionneur 100, agissant sur une fourchette de commande 96 du dispositif de couplage 90.This coupler is self-assisted, because the sliding and adhesion torque amplifies the tightening and the pressure on the friction faces. The contact of the teeth of the upper cone 92,d with the hub 94 is oblique, so that the friction torque creates an induced axial force of clamping the cones on each other. The friction torque of the teeth of the upper cone 92, d on the hub 94, creates an induced axial force of clamping of the cones 92, d, 92, c, 9, b and 92, a on each other, in phase of synchronization or adhesion during the coupled phase. The clamping force of the cones is added to that provided by the actuator 100, acting on a control fork 96 of the coupling device 90.

L’effort transmis par la fourchette 96 à l’anneau supérieur 92,d, transite par un roulement 96,a monté dans la fourchette 98. Un ressort 93 repousse l’anneau supérieur 92,d , et assure la désactivation complète du coupleur conique lors du recul de la fourchette 96 pour le découplage. Le pignon 82 reprend les efforts axiaux appliqués à la fourchette 98 et induits dans le système pendant la phase de synchronisation. Il prend appui sur une butée à aiguilles.The force transmitted by the fork 96 to the upper ring 92,d, passes through a bearing 96,a mounted in the fork 98. A spring 93 pushes the upper ring 92,d, and ensures the complete deactivation of the conical coupler when the fork 96 moves back for decoupling. The pinion 82 picks up the axial forces applied to the fork 98 and induced in the system during the synchronization phase. It rests on a needle thrust bearing.

La figure 4 montre un exemple de chemin de puissance de la machine électrique 60 au différentiel 40, en passant par la deuxième engagée. Ce premier chemin de puissance entre la machine électrique, est préférentiellement utilisé sur les rapports de première et de deuxième. La démultiplication totale pour la machine électrique en passant par le rapport de première, peut dépasser la valeur de 40. Cela permet alors des décollages et le roulage en électrique, ensuite prolongé sur le rapport de deuxième. La puissance limitée d’une machine alimentée en 48V, restreint la vitesse du véhicule.FIG. 4 shows an example of the power path from the electric machine 60 to the differential 40, passing through the second engaged. This first power path between the electric machine is preferably used on the first and second ratios. The total reduction for the electric machine via first gear, can exceed the value of 40. This then allows take-offs and taxiing in electric mode, then extended to second gear. The limited power of a machine supplied with 48V, restricts the speed of the vehicle.

A partir d’une certaine vitesse, ou lorsque l’accélération demandée par le conducteur est trop forte, le moteur thermique est mis en action. Le groupe motopropulseur fonctionne alors en mode hybride, avec une machine électrique connectée par le deuxième chemin de puissance mieux adapté pour réaliser des gains en consommation. Le premier chemin de puissance est destiné à l’agrément de roulage en électrique, et pour les manœuvres à faible vitesse.From a certain speed, or when the acceleration requested by the driver is too strong, the internal combustion engine is activated. The powertrain then operates in hybrid mode, with an electric machine connected by the second power path better suited to achieving savings in consumption. The first power path is intended for driving pleasure in electric mode, and for low-speed manoeuvres.

Combinée à la démultiplication du rapport de première, la démultiplication entre la machine électrique et l’arbre primaire, permet d’atteindre, par la traction électrique, un niveau de couple à la roue suffisant pour déplacer le véhicule en toutes situations. Les éléments de transmission spécifiques à la marche arrière, peuvent être supprimés si l’on utilise le rapport de première en inversant le sens de rotation de la machine électrique. Enfin, l’association de la machine de traction à un alterno-démarreur, permet un fonctionnement en hybride série, et une utilisation de durée indéterminée, de la marche arrière.Combined with the reduction of the first gear, the reduction between the electric machine and the primary shaft, makes it possible to achieve, through electric traction, a level of torque at the wheel sufficient to move the vehicle in all situations. The transmission elements specific to reverse gear can be eliminated if the first gear is used by reversing the direction of rotation of the electric machine. Finally, the association of the traction machine with an alternator-starter, allows series hybrid operation, and use of reverse gear for an indefinite period.

Le second chemin de puissance relie l’arbre 80 à l’arbre secondaire 30, par un moyen de couplage 97 d’un pignon fou 83 en engrènement permanent avec un pignon fixe 31 porté par l’arbre secondaire 30, par l’intermédiaire du pignon fou 22 porté par l’arbre primaire 20.The second power path connects the shaft 80 to the secondary shaft 30, by means 97 of coupling an idler gear 83 in permanent mesh with a fixed gear 31 carried by the secondary shaft 30, via the idler gear 22 carried by the primary shaft 20.

Dans ce second chemin de puissance (voir figure 5), la transmission de puissance de la machine électrique aux roues, est assurée sur un unique rapport, qui est utilisable sur toute la plage de vitesses de véhicule. La connexion ou la déconnexion de la machine ont lieu en roulant avec le moteur thermique allumé. La machine n’impacte pas l’inertie à synchroniser. Il n’a pas lieu de la déconnecter lors des changements de rapports. Dans ces conditions, le simple dispositif de synchronisation et de crabotage classique 97 suffit.In this second power path (see FIG. 5), the transmission of power from the electric machine to the wheels is ensured on a single ratio, which is usable over the entire range of vehicle speeds. The connection or disconnection of the machine takes place while driving with the heat engine on. The machine does not impact the inertia to be synchronized. There is no need to disconnect it when changing gears. Under these conditions, the simple synchronization and conventional dog clutch device 97 suffices.

L’intérêt de ce deuxième type d’électrification est de pouvoir utiliser la machine électrique pour fournir ou pour prélever de l’énergie délivrée par le moteur thermique, de manière à le placer sur un meilleur point de fonctionnement à faible charge. Au lever de pied, la boîte de vitesses peut être découplée du moteur thermique, grâce à un embrayage automatisé, en arrêtant le moteur, dans un mode dit de «sailing stop». La machine électrique peut éventuellement maintenir la vitesse du véhicule, ou simuler un frein moteur pour récupérer une partie de l’énergie cinétique du véhicule, ou pour accentuer la récupération, si la pédale de frein est activée.The advantage of this second type of electrification is to be able to use the electric machine to supply or to take energy delivered by the heat engine, so as to place it on a better operating point at low load. On lifting the foot, the gearbox can be decoupled from the internal combustion engine, thanks to an automated clutch, by stopping the engine, in a so-called “ sailing stop ” mode. The electric machine can possibly maintain the speed of the vehicle, or simulate an engine brake to recover part of the kinetic energy of the vehicle, or to accentuate the recovery, if the brake pedal is activated.

Les deux types d’électrification disponibles sont complémentaires : le premier est performant pour les prestations roulage et performances en roulage en électrique, et le second pour réduire la consommation.The two types of electrification available are complementary: the first is efficient for driving performance and driving performance in electric mode, and the second to reduce consumption.

- l’association de la machine de traction à un alterno-démarreur permet un fonctionnement en hybride série, et un roulage de durée indéterminée en marche arrière.The hybrid traction device that is proposed has many advantages:

- when the gear ratio between the electric machine and the primary shaft is chosen to ensure the torque required to start the engine, starting is possible by putting the gearbox in neutral and closing the clutch, so that the classic pinion starter can be removed;
- by closing the clutch with the gearbox in neutral, the electric machine can recharge the batteries of the stationary vehicle when it is driven by the internal combustion engine;
- combined with the reduction of the first gear, the reduction between the electric machine and the primary shaft, makes it possible to achieve, by electric traction, a level of torque at the wheel sufficient to move the vehicle in all situations;
- the gearbox does not need a specific reverse gear mechanism;
- the association of the traction machine with an alternator-starter allows series hybrid operation, and rolling of indefinite duration in reverse.
