Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un groupe motopropulseur pour un véhicule automobile à propulsion hybride.  The present invention relates to a powertrain for a motor vehicle with hybrid propulsion.

On entend ici par"propulsion hybride"une propulsion qui est réalisée à partir d'un moteur thermique et/ou d'un moteur électrique, le véhicule étant équipé de ces deux types de moteur.  The term “hybrid propulsion” is understood here to mean propulsion which is produced from a heat engine and / or an electric motor, the vehicle being equipped with these two types of engine.

Ainsi, le groupe motopropulseur qui fait l'objet de l'invention est du type comprenant un moteur thermique et un moteur électrique, ces deux moteurs étant destinés à entraîner le ou les arbres primaires menants d'une boîte de vitesses.  Thus, the powertrain which is the subject of the invention is of the type comprising a heat engine and an electric motor, these two motors being intended to drive the primary drive shaft (s) of a gearbox.

L'invention a pour but de proposer un groupe motopropulseur de ce type qui permet, avec un nombre réduit de commandes, d'assurer la recharge des batteries du moteur électrique, lors de l'arrêt du véhicule, ainsi que le démarrage du véhicule à l'arrêt, ce groupe motopropulseur présentant par ailleurs une structure compacte.  The invention aims to provide a powertrain of this type which allows, with a reduced number of commands, to ensure the recharging of the batteries of the electric motor, when the vehicle is stopped, as well as the starting of the vehicle at stopping, this powertrain also having a compact structure.

Ce but est atteint, conformément à l'invention, grâce au fait que le rotor du moteur électrique est relié à chaque arbre primaire de la boîte de vitesses par l'intermédiaire d'un embrayage, le moteur thermique étant relié audit rotor par l'intermédiaire d'un autre embrayage.  This object is achieved, in accordance with the invention, thanks to the fact that the rotor of the electric motor is connected to each primary shaft of the gearbox by means of a clutch, the heat engine being connected to said rotor by the through another clutch.

Avec cette construction, le rotor du moteur électrique est systématiquement entraîné par le moteur thermique, lorsque celui-ci fonctionne.  With this construction, the rotor of the electric motor is systematically driven by the heat engine, when the latter is operating.

De préférence, le rotor du moteur électrique est relié par un premier embrayage à un premier arbre primaire et par un deuxième embrayage à un deuxième arbre primaire tubulaire entourant le premier arbre primaire.  Preferably, the rotor of the electric motor is connected by a first clutch to a first primary shaft and by a second clutch to a second tubular primary shaft surrounding the first primary shaft.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

Dans un mode avantageux de réalisation, le premier arbre primaire porte les pignons correspondant à des rapports de vitesses impairs, tandis que le deuxième arbre primaire porte les pignons correspondant à des rapports de vitesses pairs. In an advantageous embodiment, the first primary shaft carries the pinions corresponding to odd speed ratios, while the second primary shaft carries the pinions corresponding to even speed ratios.

Dans un mode particulier de réalisation, les embrayages sont du type humide.  In a particular embodiment, the clutches are of the wet type.

Dans ce cas, l'alimentation hydraulique de ces embrayages est avantageusement réalisée au moyen de canaux ménagés dans le carter du groupe motopropulseur.  In this case, the hydraulic supply of these clutches is advantageously carried out by means of channels provided in the casing of the powertrain.

De façon à augmenter la compacité du groupe motopropulseur, chaque embrayage reliant le rotor à un arbre primaire de la boîte de vitesses est avantageusement logé sous ledit rotor.  In order to increase the compactness of the powertrain, each clutch connecting the rotor to a primary shaft of the gearbox is advantageously housed under said rotor.

L'invention concerne également un véhicule automobile à propulsion hybride comportant un groupe motopropulseur tel que décrit précédemment.  The invention also relates to a hybrid propulsion motor vehicle comprising a powertrain as described above.

L'invention sera mieux comprise et d'autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement de la description qui suit et qui est faite en référence aux dessins annexés, sur lesquels : la figure 1 est une vue générale, très schématique, d'un exemple de réalisation du groupe motopropulseur selon l'invention, avec une boîte de vitesses comportant un arbre menant, et - la figure 2 est une vue partielle en demi-coupe axiale d'un exemple de réalisation d'un groupe motopropulseur selon l'invention, avec une boîte de vitesses à deux arbres menants et des embrayages de type humide.  The invention will be better understood and other objects, advantages and characteristics thereof will appear more clearly from the description which follows and which is given with reference to the appended drawings, in which: FIG. 1 is a general view, very schematic , of an exemplary embodiment of the powertrain according to the invention, with a gearbox comprising a drive shaft, and - Figure 2 is a partial view in axial half-section of an exemplary embodiment of a powertrain according to the invention, with a gearbox with two driving shafts and wet type clutches.

En référence tout d'abord à la figure 1, la référence XX'désigne la ligne primaire de la boîte de vitesses. Referring first to Figure 1, the reference XX 'denotes the primary line of the gearbox.

Le groupe motopropulseur comporte un moteur thermique, par exemple un moteur à quatre temps, à essence ou du type diesel, qui porte la référence 1. Le moteur électrique est référencé 2. Il comporte un stator central 3 et un rotor annulaire 4.  The powertrain comprises a heat engine, for example a four-stroke engine, petrol or of the diesel type, which bears the reference 1. The electric motor is referenced 2. It comprises a central stator 3 and an annular rotor 4.

Le stator 3 est ici solidaire d'une partie fixe 5 constitutive du carter du groupe motopropulseur.  The stator 3 is here secured to a fixed part 5 constituting the casing of the powertrain.

L'arbre de sortie 6 du moteur thermique est relié au rotor 4 du moteur électrique 2, par l'intermédiaire d'un embrayage 7.  The output shaft 6 of the heat engine is connected to the rotor 4 of the electric motor 2, by means of a clutch 7.

Par ailleurs, la ligne primaire de la boîte de vitesses comporte un arbre menant 8 qui est relié au rotor 4 du moteur électrique 2, par l'intermédiaire d'un embrayage 9.  Furthermore, the primary line of the gearbox comprises a driving shaft 8 which is connected to the rotor 4 of the electric motor 2, by means of a clutch 9.

Ainsi, dans ce groupe motopropulseur, l'arbre 8 de la boîte de vitesses est entraîné en rotation par le moteur thermique 1, par l'intermédiaire du rotor 4 du moteur électrique 2, lorsque les deux embrayages 7 et 9 sont en position embrayée.  Thus, in this powertrain, the shaft 8 of the gearbox is rotated by the heat engine 1, via the rotor 4 of the electric motor 2, when the two clutches 7 and 9 are in the engaged position.

L'arbre 8 de la boîte de vitesses peut également être entraîné uniquement par le moteur électrique 2, l'embrayage 7 étant en position débrayée et l'embrayage 9 en position embrayée.  The shaft 8 of the gearbox can also be driven only by the electric motor 2, the clutch 7 being in the disengaged position and the clutch 9 in the engaged position.

Ainsi, quel que soit le mode d'entraînement de l'arbre menant de la boîte de vitesses, l'entraînement de cet arbre fait toujours intervenir le rotor 4 du moteur électrique 2.  Thus, whatever the drive mode of the drive shaft of the gearbox, the drive of this shaft always involves the rotor 4 of the electric motor 2.

Cette structure particulière du groupe motopropulseur permet de commander facilement la recharge  This particular structure of the powertrain makes it easy to control the refill

<Desc/Clms Page number 4><Desc / Clms Page number 4>

de la batterie du moteur électrique, lorsque le véhicule automobile est à l'arrêt, alors que le moteur thermique 1 fonctionne.  of the battery of the electric motor, when the motor vehicle is stopped, while the heat engine 1 is operating.

Dans cet état du véhicule, l'embrayage 9 est en position débrayée puisqu'il n'est pas nécessaire d'entraîner les roues du véhicule et l'embrayage 7 est en position embrayée.  In this state of the vehicle, the clutch 9 is in the disengaged position since it is not necessary to drive the wheels of the vehicle and the clutch 7 is in the engaged position.

Ainsi, le moteur thermique 1 entraîne en rotation le rotor 4, par l'intermédiaire de son arbre de sortie 6, ce qui assure la recharge de la batterie.  Thus, the heat engine 1 rotates the rotor 4, via its output shaft 6, which ensures the recharging of the battery.

La recharge de la batterie est donc obtenue simplement en commandant le débrayage de l'embrayage 9.  The recharging of the battery is therefore obtained simply by controlling the disengagement of the clutch 9.

Lorsque le conducteur souhaite redémarrer le véhicule qui est alors à l'arrêt, deux situations se présentent.  When the driver wishes to restart the vehicle which is then stopped, two situations arise.

Si le moteur thermique 1 est déjà en fonctionnement, il suffit de placer l'embrayage 9 en position embrayée.  If the heat engine 1 is already in operation, it suffices to place the clutch 9 in the engaged position.

Si le moteur thermique 1 est éteint, il est possible d'assurer le démarrage du véhicule par l'intermédiaire du moteur électrique 2, en plaçant l'embrayage 9 en position embrayée.  If the heat engine 1 is switched off, it is possible to start the vehicle via the electric motor 2, by placing the clutch 9 in the engaged position.

Le moteur thermique 1 pourra ensuite prendre le relais du. moteur électrique 2, l'embrayage 7 étant alors placé en position embrayée. Le moteur électrique pourra alors éventuellement être arrêté, l'entraînement de l'arbre menant 8 de la boite de vitesses s'effectuant par le moteur thermique 1, par l'intermédiaire du rotor 4 du moteur électrique 2.  The engine 1 can then take over from. electric motor 2, the clutch 7 then being placed in the engaged position. The electric motor can then possibly be stopped, the drive of the driving shaft 8 of the gearbox being effected by the heat engine 1, by means of the rotor 4 of the electric motor 2.

On se réfère maintenant à la figure 2 qui illustre partiellement un exemple de réalisation particulier du groupe motopropulseur selon l'invention.  Referring now to Figure 2 which partially illustrates a particular embodiment of the powertrain according to the invention.

<Desc/Clms Page number 5> <Desc / Clms Page number 5>

Sur la figure 2, la référence XX'désigne toujours la ligne primaire de la boîte de vitesses. In Figure 2, the reference XX 'always denotes the primary line of the gearbox.

La ligne primaire XX'est ici constituée d'une paire d'arbres menants, à savoir un arbre principal 10 et un arbre auxiliaire tubulaire 20 qui entoure l'arbre principal 10 et qui est libre en rotation par rapport à ce dernier.  The primary line XX 'here consists of a pair of drive shafts, namely a main shaft 10 and a tubular auxiliary shaft 20 which surrounds the main shaft 10 and which is free to rotate relative to the latter.

Chacun de ces arbres menants 10,20 porte des pignons qui ne sont pas illustrés sur la figure 2.  Each of these leading trees 10,20 carries gears which are not illustrated in FIG. 2.

De préférence, ces pignons sont répartis sur l'arbre menant principal 10 et sur l'arbre menant auxiliaire 20 de telle sorte que leur diamètre va dans un ordre croissant et alternativement sur l'un et l'autre des deux arbres menants.  Preferably, these pinions are distributed on the main driving shaft 10 and on the auxiliary driving shaft 20 so that their diameter goes in an increasing order and alternately on one and the other of the two driving shafts.

Ainsi, la présence de deux arbres menants et cette disposition particulière des pignons permet d'assurer des passages de vitesses sans à-coups.  Thus, the presence of two drive shafts and this particular arrangement of the pinions makes it possible to ensure smooth shifts.

Par ailleurs, il est avantageux que les pignons correspondant à des rapports de vitesses impairs soient portés par l'arbre principal 10, les pignons correspondant à des rapports de vitesses pairs étant alors portés par l'arbre auxiliaire 20.  Furthermore, it is advantageous for the pinions corresponding to odd speed ratios to be carried by the main shaft 10, the pinions corresponding to even speed ratios then being carried by the auxiliary shaft 20.

Dans cette configuration, le pignon correspondant à la première vitesse est alors porté par l'arbre principal 10 qui peut être avantageusement un arbre plein, ce qui permet de limiter la taille du pignon correspondant situé sur la ligne secondaire (non représentée).  In this configuration, the pinion corresponding to the first speed is then carried by the main shaft 10 which can advantageously be a solid shaft, which makes it possible to limit the size of the corresponding pinion located on the secondary line (not shown).

Le groupe motopropulseur comporte un moteur thermique (non illustré) dont l'arbre de sortie présente une extrémité référencée 30.  The powertrain includes a heat engine (not shown), the output shaft of which has an end referenced 30.

<Desc/Clms Page number 6> <Desc / Clms Page number 6>

Le groupe motopropulseur comporte également un moteur électrique 40 avec un rotor 41, des bobinages 42 et un stator 43. The powertrain also includes an electric motor 40 with a rotor 41, windings 42 and a stator 43.

Le stator 43 est ici fixé au carter 50 du groupe motopropulseur.  The stator 43 is here fixed to the casing 50 of the powertrain.

Dans cet exemple de réalisation, le rotor annulaire 41 est associé à une pièce de liaison 44 formée de plusieurs éléments et qui assure la liaison entre le rotor 41 et les différents embrayages reliés au moteur thermique ainsi qu'à chacun des arbres menants de la ligne primaire.  In this exemplary embodiment, the annular rotor 41 is associated with a connecting piece 44 formed of several elements and which provides the connection between the rotor 41 and the different clutches connected to the heat engine as well as to each of the driving shafts of the line. primary.

Cette pièce de liaison 44 comporte un premier élément 440, fixe en rotation par rapport au rotor 41, dans lequel est logé un premier embrayage 11.  This connecting piece 44 comprises a first element 440, fixed in rotation relative to the rotor 41, in which is housed a first clutch 11.

Cet embrayage 11 est lui-même relié à l'arbre menant principal 10 par l'intermédiaire d'un premier moyen de liaison 12.  This clutch 11 is itself connected to the main driving shaft 10 by means of a first connecting means 12.

L'élément 440 présente également un logement pour un deuxième embrayage 21 relié au deuxième arbre primaire 20 tubulaire par l'intermédiaire d'un deuxième moyen de liaison 22.  The element 440 also has a housing for a second clutch 21 connected to the second tubular primary shaft 20 via a second connecting means 22.

Cet élément 440, lié en rotation au rotor 41, est susceptible de tourner autour du carter 50, grâce à la présence de joints tournants 441.  This element 440, linked in rotation to the rotor 41, is capable of rotating around the casing 50, thanks to the presence of rotary joints 441.

Les deux embrayages 11 et 21 sont des embrayages de type humide dont le fonctionnement sera décrit plus loin.  The two clutches 11 and 21 are wet type clutches, the operation of which will be described later.

La pièce de liaison 44 comporte un autre élément

Figure img00060001

442 qui est solidaire en rotation de la pièce 440, cette pièce 442 étant elle-même solidaire en rotation d'une troisième pièce 443. The connecting piece 44 has another element
Figure img00060001

442 which is integral in rotation with the piece 440, this piece 442 itself being integral in rotation with a third piece 443.

<Desc/Clms Page number 7> <Desc / Clms Page number 7>

Dans cet élément 443 est logé l'embrayage 31 qui permet de relier le rotor 41 à l'extrémité 30 de l'arbre de sortie du moteur thermique.  In this element 443 is housed the clutch 31 which makes it possible to connect the rotor 41 to the end 30 of the output shaft of the heat engine.

L'élément 442 peut librement tourner par rapport au carter 50 grâce aux roulements 444.  The element 442 can freely rotate relative to the casing 50 thanks to the bearings 444.

L'élément 443 peut, quant à lui, librement tourner par rapport à ce carter 50, grâce à la présence des joints tournants 445.  The element 443 can, for its part, freely rotate relative to this casing 50, thanks to the presence of the rotary joints 445.

Dans l'exemple de réalisation qui vient d'être décrit, le rotor 41 est associé à une pièce de liaison 44 de forme complexe. On pourrait également prévoir de former directement le rotor 41 en une seule pièce.  In the embodiment which has just been described, the rotor 41 is associated with a connecting piece 44 of complex shape. One could also plan to directly form the rotor 41 in one piece.

Les embrayages 11, 21 et 31 sont des embrayages de type humide dont l'alimentation hydraulique est assurée par une série de canaux ménagés dans le carter 50 et portant les références 51 à 55.  The clutches 11, 21 and 31 are wet type clutches the hydraulic supply of which is ensured by a series of channels provided in the casing 50 and bearing the references 51 to 55.

Ces embrayages de type humide sont bien connus de l'homme du métier.  These wet type clutches are well known to those skilled in the art.

Leur fonctionnement sera rappelé en référence à l'embrayage 31.  Their operation will be recalled with reference to the clutch 31.

Cet embrayage 31 comporte une série de disques 310 qui sont, dans l'état illustré à la figure 2, séparés les uns des autres.  This clutch 31 comprises a series of discs 310 which are, in the state illustrated in FIG. 2, separated from each other.

L'embrayage 31 comporte également une première pièce 311 qui joue le rôle d'un piston et qui définit, avec le troisième élément 443 de la pièce de liaison 44, une première chambre 313, et une deuxième pièce 312 qui définit avec la première pièce 311 une deuxième chambre 314.  The clutch 31 also includes a first part 311 which acts as a piston and which defines, with the third element 443 of the connecting part 44, a first chamber 313, and a second part 312 which defines with the first part 311 a second bedroom 314.

La première chambre 313 est susceptible d'être alimentée en liquide sous pression par l'intermédiaire  The first chamber 313 is capable of being supplied with liquid under pressure via

<Desc/Clms Page number 8><Desc / Clms Page number 8>

d'un canal 55a ménagé à la fois dans le carter 50 et dans le troisième élément 443.  a channel 55a formed both in the casing 50 and in the third element 443.

La deuxième chambre 314 est reliée au canal 55, par l'intermédiaire d'un canal 55b ménagé à la fois dans le carter 50 et dans le troisième élément 443.  The second chamber 314 is connected to the channel 55, via a channel 55b formed both in the casing 50 and in the third element 443.

Lorsque la chambre 313 est alimentée en fluide sous pression par l'intermédiaire du canal 55a, le premier élément 311 se déplace vers la droite, par rapport à la figure, et applique donc les disques 310 les uns contre les autres. Ceci place l'embrayage 31 en position embrayée.  When the chamber 313 is supplied with pressurized fluid via the channel 55a, the first element 311 moves to the right, with respect to the figure, and therefore applies the discs 310 against each other. This places the clutch 31 in the engaged position.

On notera que la chambre 314, dite"chambre de compensation"est alimentée en permanence, ce qui rappelle constamment l'embrayage 31 en position débrayée, tandis que la chambre 313, dite"chambre de pression", n'est alimentée que pour mettre l'embrayage en position embrayée, et mise à l'évacuation lorsque l'on veut débrayer.  It will be noted that the chamber 314, called the "compensation chamber" is permanently supplied, which constantly reminds the clutch 31 in the disengaged position, while the chamber 313, called the "pressure chamber", is supplied only to put the clutch in the engaged position, and evacuation when one wants to disengage.

Les embrayages 11 et 21 sont construits de façon similaire et ne seront pas décrits en détail.  Clutches 11 and 21 are constructed similarly and will not be described in detail.

Ainsi, l'embrayage 11 est alimenté en fluide sous pression au moyen du canal 54 et des canaux radiaux 54a et 54b, tandis que l'embrayage 21 est alimenté en fluide sous pression par l'intermédiaire de ce même canal 54 et des canaux radiaux 54c et 54d.  Thus, the clutch 11 is supplied with pressurized fluid by means of the channel 54 and the radial channels 54a and 54b, while the clutch 21 is supplied with pressurized fluid by means of this same channel 54 and the radial channels. 54c and 54d.

Dans l'exemple décrit ici, il y a une alimentation commune pour les chambres de compensation telles que 314 et des alimentations individuelles (avec des moyens de commande qui n'ont pas été représentés sur le dessin) pour les chambres de pression telles que 313.  In the example described here, there is a common supply for the compensation chambers such as 314 and individual supplies (with control means which have not been shown in the drawing) for the pressure chambers such as 313 .

<Desc/Clms Page number 9> <Desc / Clms Page number 9>

Le fonctionnement du groupe motopropulseur est le suivant. The operation of the powertrain is as follows.

Lors du démarrage du véhicule, on peut par exemple choisir d'utiliser le moteur électrique 40.  When starting the vehicle, one can for example choose to use the electric motor 40.

Ce moteur électrique 40 est alors alimenté et l'embrayage 11 mis en position embrayée, l'embrayage 21 et l'embrayage 31 étant tous les deux en position débrayée.  This electric motor 40 is then supplied and the clutch 11 is put in the engaged position, the clutch 21 and the clutch 31 being both in the disengaged position.

Ceci permet d'entraîner l'arbre menant principal 10 qui porte le pignon correspondant à la première vitesse.  This allows to drive the main driving shaft 10 which carries the pinion corresponding to the first speed.

Si l'on choisit de rester en mode électrique, l'embrayage 11 est placé en position débrayée et l'embrayage 21 en position embrayée pour passer en seconde. Ces deux embrayages sont commandés successivement lors des changements de vitesse.  If one chooses to remain in electric mode, the clutch 11 is placed in the disengaged position and the clutch 21 in the engaged position to pass in second. These two clutches are controlled successively during gear changes.

Le moteur électrique peut également être utilisé au démarrage, comme indiqué précédemment, le moteur thermique prenant le relais après le démarrage.  The electric motor can also be used at start-up, as indicated above, the internal combustion engine taking over after starting.

L'embrayage 31 est alors placé en position embrayée, le moteur thermique entraînant alors le rotor 41 du moteur électrique, qui lui-même entraîne l'arbre menant principal 10 ou l'arbre menant auxiliaire 20, suivant le rapport de vitesse choisi.  The clutch 31 is then placed in the engaged position, the heat engine then driving the rotor 41 of the electric motor, which itself drives the main driving shaft 10 or the auxiliary driving shaft 20, depending on the gear ratio chosen.

Lorsque le véhicule est à l'arrêt, alors que le moteur thermique fonctionne, les deux embrayages 11 et 21 sont en position débrayée, tandis que l'embrayage 31 est en position embrayée.  When the vehicle is stopped, while the engine is running, the two clutches 11 and 21 are in the disengaged position, while the clutch 31 is in the engaged position.

Ainsi, le moteur thermique entraîne le rotor 41, ce qui assure la recharge de la batterie qui alimente le moteur électrique.  Thus, the heat engine drives the rotor 41, which ensures the recharging of the battery which powers the electric motor.

Lorsque le conducteur souhaite repartir, il suffit de commander l'embrayage 11 pour le mettre en position  When the driver wishes to leave, it suffices to control the clutch 11 to put it in position

<Desc/Clms Page number 10><Desc / Clms Page number 10>

embrayée et l'arbre menant principal 10 est alors entraîné par le moteur thermique, et ceci par l'intermédiaire du rotor 41.  engaged and the main driving shaft 10 is then driven by the heat engine, and this via the rotor 41.

Ainsi, la structure du groupe motopropulseur selon l'invention permet d'assurer la charge de la batterie lors de l'arrêt du véhicule ainsi que le démarrage du véhicule grâce à un nombre de commandes qui est réduit.  Thus, the structure of the powertrain according to the invention makes it possible to ensure the battery charge when the vehicle is stopped as well as the vehicle starting thanks to a number of commands which is reduced.

La présence d'un démarreur est également rendue inutile, ce qui entraîne des réductions de coûts.  The presence of a starter is also made unnecessary, which leads to cost reductions.

Dans le mode de réalisation illustré à la figure 2, l'encombrement axial du groupe motopropulseur est limité puisque les embrayages reliant le rotor à chacun des deux arbres menants sont logés sous le rotor ou encore de façon radiale entre le rotor et l'axe de la ligne primaire XX'.  In the embodiment illustrated in FIG. 2, the axial size of the powertrain is limited since the clutches connecting the rotor to each of the two driving shafts are housed under the rotor or even radially between the rotor and the axis of the primary line XX '.

Les signes de référence insérés après les caractéristiques techniques figurant dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et ne sauraient en limiter la portée. The reference signs inserted after the technical characteristics appearing in the claims have the sole purpose of facilitating the understanding of the latter and should not limit their scope.
