Description

Dispositif de transmission de vitesse pour le déplacement d'un véhicule automobile, notamment d'un véhicule motorisé à au moins deux roues, et groupe motopropulseur utilisant un tel dispositif.  Speed transmission device for moving a motor vehicle, in particular a motorized vehicle with at least two wheels, and powertrain using such a device.
La présente invention se rapporte à un dispositif de transmission de vitesse pour le déplacement d'un véhicule automobile, notamment d'un véhicule motorisé à au moins deux roues, ainsi qu'à un groupe motopropulseur utilisant ce dispositif de transmission de vitesse. The present invention relates to a speed transmission device for moving a motor vehicle, in particular a motorized vehicle with at least two wheels, and a powertrain using this speed transmission device.
Dans l'exemple décrit dans le document FR 2 81 1 395, ce dispositif de transmission de vitesse comprend un arbre moteur placé sensiblement parallèlement à un arbre récepteur qui est généralement utilisé pour entraîner la ou les roues motrices du véhicule. In the example described in document FR 2 81 1 395, this speed transmission device comprises a motor shaft placed substantially parallel to a receiving shaft which is generally used to drive the driving wheel or wheels of the vehicle.
Dans ce type de transmission, l'arbre moteur est entraîné en rotation par le moteur à combustion interne et porte, de manière fixe, deux roues menantes qui sont chacune en prise avec des roues menées réceptrices portées par l'arbre récepteur en étant montées folles sur cet arbre. Cet arbre récepteur porte également des baladeurs à débattement alternatif qui permettent de rendre solidaires en rotation les roues menées réceptrices avec cet arbre. In this type of transmission, the drive shaft is rotated by the internal combustion engine and carries, in a fixed manner, two driving wheels which are each engaged with driven wheels carried by the receiving shaft by being mounted crazy. on this tree. This receiver shaft also carries walk-around players which make it possible to rotate the driven wheels together with this shaft.
Ainsi, en fonctionnement, le véhicule est entraîné en déplacement à différentes vitesses en agissant sur les différents baladeurs que portent l'arbre récepteur pour solidariser une des roues menantes de l'arbre moteur avec une des roues réceptrices de cet arbre récepteur. Thus, in operation, the vehicle is driven in motion at different speeds by acting on the various players that carry the receiving shaft to secure one of the driving wheels of the drive shaft with one of the receiving wheels of the receiving shaft.
Comme cela est bien connu, ce type de transmission peut être utilisé avec un véhicule de type hybride qui combine, comme moyen de déplacement du véhicule, le moteur à combustion interne à une machine motrice/génératrice rotative, comme une machine électrique reliée à une source électrique, telle qu'un ou plusieurs accumulateurs électriques. As is well known, this type of transmission can be used with a hybrid type vehicle that combines, as means of moving the vehicle, the internal combustion engine to a driving machine / generator rotary, like an electric machine connected to an electrical source, such as one or more electric accumulators.
Cette combinaison permet d'optimiser les performances de ce véhicule, notamment en diminuant la consommation en carburant de l'ensemble du dispositif, tout en préservant l'environnement par des rejets limités de polluants dans l'atmosphère. This combination optimizes the performance of this vehicle, in particular by reducing the fuel consumption of the entire device, while preserving the environment by limited releases of pollutants into the atmosphere.
Ainsi, lorsque l'on souhaite déplacer le véhicule avec un couple important sur une grande plage de vitesses tout en limitant la génération de gaz polluant d'échappement et de bruit, comme dans un site urbain, l'utilisation de la machine électrique est privilégiée pour entraîner en déplacement ce véhicule.  Thus, when it is desired to move the vehicle with a large torque over a wide range of speeds while limiting the generation of pollutant exhaust gas and noise, as in an urban site, the use of the electric machine is preferred to train on the move this vehicle.
Par contre, le moteur thermique est utilisé pour déplacer ce véhicule lors d'utilisations où une puissance d'entraînement élevée et une grande autonomie de fonctionnement sont demandées. On the other hand, the engine is used to move this vehicle for uses where high driving power and a long operating autonomy are required.
Ce dispositif de transmission bien que donnant satisfaction présente néanmoins des inconvénients non négligeables. En effet, il est nécessaire, pour obtenir la vitesse de déplacement souhaitée, d'accoupler ou de désaccoupler certains éléments du dispositif, comme les roues dentées réceptrices. Ceci a pour effet d'allonger le temps de passage d'une vitesse à une autre en entraînant un inconfort de conduite. De plus, le dispositif de transmission doit comporter une multiplicité d'actionneurs pour commander les baladeurs. Ces actionneurs augmentent le coût de réalisation du dispositif et peuvent être la source de pannes et/ou de dysfonctionnements. En outre, ces actionneurs doivent être contrôlés par une unité de calcul, comme le calculateur que comporte habituellement le moteur, ce qui nécessite d'augmenter la capacité de ce calculateur. La présente invention se propose de remédier aux inconvénients mentionnés ci-dessus grâce à un dispositif de transmission de vitesse de réalisation simple et peu coûteuse. This transmission device, although satisfactory, nevertheless has significant disadvantages. Indeed, it is necessary, to obtain the desired speed of movement, to couple or uncouple some elements of the device, such as the gears receiving. This has the effect of lengthening the time of passage from one speed to another resulting in driving discomfort. In addition, the transmission device must include a multiplicity of actuators to control the players. These actuators increase the cost of producing the device and can be the source of faults and / or malfunctions. In addition, these actuators must be controlled by a computing unit, as the calculator that usually includes the engine, which requires increasing the capacity of this computer.

Comme illustré sur la figure 1 , le dispositif de transmission de vitesse 10 comprend un arbre moteur 12 portant deux roues dentées de diamètre différent 14 et 1 6, un accouplement à commande contrôlée 18 pour la roue 14 et un autre accouplement à commande contrôlée 20 pour la roue 16. En considérant la figure 1 , la roue dentée 14 (dénommée petite roue dentée) est placée sur un fourreau 22 entourant l'arbre 12 en étant libre en rotation sur cet arbre mais fixe en translation. Cette roue a la possibilité d'être reliée en rotation à cet arbre par l'accouplement à commande contrôlée 18, comme un embrayage à disque de friction ou un synchroniseur. A gauche de cette petite roue dentée, l'autre roue dentée 1 6 (ou grande roue dentée) est placée sur un fourreau 24 entourant l'arbre 12 en étant libre en rotation sur cet arbre mais fixe en translation. L'accouplement à commande contrôlée 20, comme un embrayage à disque de friction ou un synchroniseur, permet de relier en rotation la roue 1 6 avec l'arbre moteur 1 2. As illustrated in FIG. 1, the speed transmission device 10 comprises a driving shaft 12 carrying two different diameter toothed wheels 14 and 16, a controlled-control coupling 18 for the wheel 14 and another controlled-control coupling 20 for the wheel 16. Referring to Figure 1, the toothed wheel 14 (called small gear) is placed on a sleeve 22 surrounding the shaft 12 being free to rotate on the shaft but fixed in translation. This wheel has the possibility of being rotatably connected to this shaft by the controlled-control coupling 18, such as a friction disk clutch or a synchronizer. To the left of this small toothed wheel, the other toothed wheel 1 6 (or large toothed wheel) is placed on a sleeve 24 surrounding the shaft 12 being free to rotate on this shaft but fixed in translation. The controlled-control coupling 20, such as a friction disc clutch or a synchronizer, makes it possible to connect the wheel 1 6 in rotation with the driving shaft 1 2.
Pour des raisons de simplification dans la suite de la description, les roues dentées 14 et 16 sont dénommées roues dentées menantes. A titre d'exemple et comme mieux illustré sur la figure 1 , les accouplements à commande contrôlée sont des embrayages à disque de friction et comprennent un plateau de réaction 26, 28 fixe sur l'arbre moteur 12, un plateau de pression 30, 32 , libre en translation mais fixe en rotation avec le plateau de réaction en étant commandé en déplacement vers le plateau de réaction par tous moyens connus, comme des leviers 34, 36, et un disque de friction 38, 40 libre en translation sur les fourreaux 22, 24 mais fixe en rotation en étant placé entre le plateau de pression et le plateau de réaction. For reasons of simplification in the rest of the description, the gears 14 and 16 are called driving gears. By way of example and as best illustrated in FIG. 1, the controlled-control couplings are friction disc clutches and comprise a reaction plate 26, 28 fixed to the drive shaft 12, a pressure plate 30, 32 , free in translation but fixed in rotation with the reaction plate being controlled in displacement towards the reaction plate by any known means, such as levers 34, 36, and a friction disc 38, 40 free in translation on the sleeves 22 But rotates while being placed between the pressure plate and the reaction plate.
Ce dispositif comprend également un arbre intermédiaire de transmission de mouvement de rotation 42, placé sensiblement parallèlement à l'arbre moteur 12 et qui porte deux roues dentées 44, 46 fixes sur cet arbre et de diamètre différent en engrenant avec les roues dentées de l'arbre moteur. La roue dentée 44 (grande roue dentée intermédiaire) de cet arbre de liaison coopère avec la petite roue dentée menante et la roue dentée 46 (petite roue dentée intermédiaire) coopère avec la grande roue dentée menante. Ce dispositif comprend aussi, sensiblement parallèlement à l'arbre moteur 12 et à l'arbre intermédiaire 42, un arbre récepteur 48 qui porte, comme pour l'arbre moteur 12, deux roues dentées réceptrices 50 et 52 de diamètre différent. This device also comprises an intermediate shaft for transmitting rotational movement 42, placed substantially parallel to the drive shaft 12 and carrying two toothed wheels 44, 46 fixed to this shaft and of different diameter by meshing with the toothed wheels of the engine shaft. The toothed wheel 44 (large intermediate gear) of this connecting shaft cooperates with the small drive gear and the gear wheel 46 (small intermediate gear) cooperates with the large drive gear. This device also comprises, substantially parallel to the drive shaft 12 and the intermediate shaft 42, a receiving shaft 48 which carries, as for the drive shaft 12, two gears receiving receptors 50 and 52 of different diameter.
Les roues dentées réceptrices sont placées sur l'arbre récepteur d'une façon symétrique à celle de l'arbre moteur. The receiver gears are placed on the receiving shaft in a manner symmetrical to that of the motor shaft.
Ainsi, la roue dentée 50 (petite roue dentée menée) est placée sur un fourreau 54 entourant l'arbre récepteur 48 en étant libre en rotation sur cet arbre mais fixe en translation. Cette roue dentée 50 a la possibilité d'être reliée en rotation à cet arbre récepteur par un accouplement à commande contrôlée 56, comme un embrayage à disque de friction ou un synchroniseur. Thus, the toothed wheel 50 (small driven gear wheel) is placed on a sleeve 54 surrounding the receiving shaft 48 being free to rotate on the shaft but fixed in translation. This toothed wheel 50 has the possibility of being connected in rotation to this receiving shaft by a controlled-control coupling 56, such as a friction disc clutch or a synchronizer.
Comme pour les accouplements placés sur l'arbre moteur, l'accouplement à commande contrôlée 56 est ici un embrayage à friction avec un plateau de réaction 58 fixe sur l'arbre récepteur, un plateau de pression 60, libre en translation mais fixe en rotation avec le plateau de réaction, en étant commandé en déplacement vers le plateau de réaction par tous moyens connus, comme des leviers 62, et un disque de friction 64 libre en translation sur le fourreau 54 mais fixe en rotation.  As for the couplings placed on the motor shaft, the controlled-control coupling 56 is here a friction clutch with a reaction plate 58 fixed on the receiving shaft, a pressure plate 60, free in translation but fixed in rotation with the reaction plate, being controlled in displacement towards the reaction plate by any known means, such as levers 62, and a friction disc 64 free in translation on the sleeve 54 but fixed in rotation.
Comme mieux illustré sur la figure 1 , la roue dentée 52 (grande roue dentée menée) est placée sur l'arbre 48 au travers d'un accouplement unidirectionnel 66, comme une roue libre. As best illustrated in FIG. 1, the gearwheel 52 (large driven gearwheel) is placed on the shaft 48 through a unidirectional coupling 66, such as a freewheel.
Comme mieux visible sur la figure, la grande roue menée 52 engrène avec la petite roue intermédiaire 46 alors que la petite roue menée 50 engrène avec la grande roue intermédiaire 44.  As best seen in the figure, the large driven wheel 52 meshes with the small intermediate wheel 46 while the small driven wheel 50 meshes with the large intermediate wheel 44.
Dans cette configuration, le dispositif de transmission comprend deux trains d'engrenages formant deux voies de transmission de mouvement de rotation T1 et T2 entre l'arbre moteur et l'arbre récepteur. L'une T2 de ces voies comprend la grande roue dentée menante 1 6, la petite roue dentée intermédiaire 46 et la grande roue menée 52. L'autre T1 de ces voies comprend, de manière symétrique, la petite roue menante 14, la grande roue intermédiaire 44 et la petite roue menée 50. Bien entendu, il est à la portée de l'homme du métier de prévoir des moyens connus, comme des actionneurs hydrauliques ou électriques ou mécaniques, pour actionner les leviers 34, 36 et 62 en fonction du rapport de vitesse souhaité. Le dispositif décrit ci-dessus permet ainsi de réaliser quatre rapports de vitesse en utilisant trois embrayages et une roue libre. In this configuration, the transmission device comprises two gear trains forming two rotational movement transmission channels T1 and T2 between the motor shaft and the receiving shaft. One T2 of these tracks includes the large driving gear 1 6, the small gear wheel intermediate 46 and the large wheel 52. The other T1 of these tracks comprises, symmetrically, the small driving wheel 14, the large intermediate wheel 44 and the small driven wheel 50. Of course, it is within the reach of the those skilled in the art to provide known means, such as hydraulic or electric or mechanical actuators, to operate the levers 34, 36 and 62 as a function of the desired speed ratio. The device described above thus makes it possible to achieve four gear ratios by using three clutches and a freewheel.
Dans un de ces rapports de vitesse, lors de la rotation de l'arbre moteur et dans la position embrayée pour l'embrayage 18 et débrayée pour les embrayages 20 et 56, la petite roue dentée menée 14 est entraînée en rotation par sa liaison avec l'arbre 12 au travers de l'embrayage 18. Cette rotation de la roue 14 est ensuite transmise à l'arbre intermédiaire 42 par la grande roue dentée intermédiaire 44, ce qui a pour effet d'entraîner en rotation la petite roue dentée intermédiaire 46. Cette petite roue entraîne à son tour la grande roue menée 52 qui retransmet cette rotation à l'arbre récepteur 48 grâce à l'action de la roue libre 66. In one of these speed ratios, during the rotation of the drive shaft and in the engaged position for the clutch 18 and disengaged for the clutches 20 and 56, the small driven gear 14 is rotated by its connection with the shaft 12 through the clutch 18. This rotation of the wheel 14 is then transmitted to the intermediate shaft 42 by the large intermediate gear wheel 44, which has the effect of driving in rotation the small intermediate gear wheel 46. This small wheel in turn drives the large driven wheel 52 which retransmits this rotation to the receiving shaft 48 through the action of the free wheel 66.
Bien entendu comme les deux embrayages 20 et 56 sont inactifs, ni la grande roue menante 1 6, ni la petite roue menée 50 ne sont entraînées en rotation par l'arbre moteur ou l'arbre récepteur et tournent de manière folle sur les arbres 12 et 48. Of course, as the two clutches 20 and 56 are inactive, neither the large driving wheel 1 6, nor the small driven wheel 50 are rotated by the motor shaft or the receiving shaft and rotate wildly on the shafts 12 and 48.
Dans un autre rapport de vitesse, l'embrayage 20 est en position embrayée et les embrayages 18 et 56 sont en position débrayée. La grande roue menante 1 6 est alors entraînée en rotation par l'arbre moteur 12 sous l'action de l'embrayage 20. Cette rotation est retransmise à l'arbre intermédiaire 42 par la petite roue intermédiaire 46 qui la communique à la grande roue menée 52. La rotation de cette grande roue menée est transmise à l'arbre récepteur 48 par la mise en action de la roue libre 66. In another gear ratio, the clutch 20 is in the engaged position and the clutches 18 and 56 are in the disengaged position. The large driving wheel 1 6 is then rotated by the drive shaft 12 under the action of the clutch 20. This rotation is transmitted to the intermediate shaft 42 by the small intermediate wheel 46 which communicates to the ferris wheel conducted 52. The rotation of this large driven wheel is transmitted to the receiving shaft 48 by the actuation of the free wheel 66.
Simultanément, la rotation de l'arbre intermédiaire 42 par la petite roue intermédiaire entraîne la rotation de la grande roue intermédiaire 44, qui entraîne à son tour la petite roue menante 14 et la petite roue menée 50. Compte tenu de la position débrayée des embrayages 18 et 56, la petite roue menante 14 et la petite roue menée 50 tournent de manière folle sur leur arbre respectif. Simultaneously, the rotation of the intermediate shaft 42 by the small intermediate wheel causes the rotation of the large intermediate wheel 44, which in turn drives the small driving wheel 14 and the small driven wheel 50. Given the disengaged position of the clutches 18 and 56, the small driving wheel 14 and the small driven wheel 50 rotate wildly on their respective shaft.
Pour un autre rapport de vitesse, les embrayages 18 et 56 sont en position embrayée et l'embrayage 20 est en position débrayée. La petite roue menante 14 est alors entraînée en rotation par l'arbre moteur par l'action de l'embrayage 18. La rotation de cette petite roue menante est communiquée à l'arbre intermédiaire 42 par la grande roue intermédiaire 44 qui la transmet à l'arbre récepteur par la petite roue menée 50 relié à cet arbre récepteur par l'action de l'embrayage 56. For another gear ratio, the clutches 18 and 56 are in the engaged position and the clutch 20 is in the disengaged position. The small driving wheel 14 is then driven in rotation by the drive shaft by the action of the clutch 18. The rotation of this small driving wheel is communicated to the intermediate shaft 42 by the large intermediate wheel 44 which transmits it to the receiving shaft by the small driven wheel 50 connected to this receiving shaft by the action of the clutch 56.
La rotation de l'arbre intermédiaire 42 par la grande roue intermédiaire 44 entraîne la rotation la petite roue 46 qui engrène avec la grande roue dentée menée 52. Cependant, compte tenu du différentiel de vitesses de rotation entre la roue menée 52 et l'arbre récepteur 38, ce dernier est désaccouplé de la grande roue menée par l'inaction de la roue libre 66. The rotation of the intermediate shaft 42 by the large intermediate wheel 44 causes the rotation of the small wheel 46 which meshes with the large driven gear 52. However, taking into account the differential speed of rotation between the driven wheel 52 and the shaft receiver 38, the latter is uncoupled from the large wheel driven by the inaction of the free wheel 66.
Bien entendu et cela compte tenu de la position débrayée de l'embrayage 20, la rotation de la petite roue intermédiaire 46 n'a aucune influence sur l'arbre menant 12 puisque la grande roue dentée menante 1 6 tourne folle sur cet arbre.  Of course and this considering the disengaged position of the clutch 20, the rotation of the small intermediate wheel 46 has no influence on the drive shaft 12 since the large driving gear 1 6 rotates crazy on this shaft.
Enfin pour le dernier rapport, les deux embrayages 20 et 56 sont en position embrayée et l'embrayage 18 est en position débrayée. La rotation de l'arbre moteur 12 est transmise, par l'action de l'embrayage 20, à la grande roue menante 1 6 qui la transmet à la petite roue dentée intermédiaire 46 de l'arbre intermédiaire 42. Ce dernier transmet cette rotation à la petite roue menée 50 par l'intermédiaire de la grande roue dentée intermédiaire 44. L'arbre récepteur est alors entraîné en rotation par l'action de l'embrayage 56 qui relie la petite roue dentée menée à cet arbre. Finally for the last report, the two clutches 20 and 56 are in the engaged position and the clutch 18 is in the disengaged position. The rotation of the drive shaft 12 is transmitted, by the action of the clutch 20, to the large driving wheel 1 6 which transmits it to the small intermediate gear wheel 46 of the shaft intermediate 42. The latter transmits this rotation to the small driven wheel 50 via the large intermediate gear wheel 44. The receiving shaft is then rotated by the action of the clutch 56 which connects the small gear wheel led to this tree.
Dans cette configuration, la rotation de l'arbre intermédiaire 42 entraîne également, par l'entremise des roues dentées intermédiaires 44 et 46, la rotation de la petite roue dentée menante 14 et de la grande roue dentée menée 52. Comme déjà mentionné, compte tenu du différentiel de vitesses de rotation entre la roue menée et l'arbre récepteur, ce dernier est désaccouplé de la grande roue menée 52 par la roue libre 66.  In this configuration, the rotation of the intermediate shaft 42 also causes, through the intermediary gears 44 and 46, the rotation of the small driving gear 14 and the large driven gear 52. As already mentioned, account Due to the difference in speed of rotation between the driven wheel and the receiver shaft, the latter is uncoupled from the large driven wheel 52 by the free wheel 66.
Ainsi, le dispositif de transmission tel que décrit ci-dessus permet de réaliser quatre rapports de vitesse avec l'avantage de disposer d'un embrayage 18 sur l'arbre moteur qui permet d'obtenir la fonction point mort sur la transmission. Il permet aussi de réaliser la fonction de décollage du véhicule depuis la vitesse nulle, ainsi que de disposer de deux rapports avec du frein moteur. Thus, the transmission device as described above makes it possible to achieve four gear ratios with the advantage of having a clutch 18 on the motor shaft which makes it possible to obtain the neutral position function on the transmission. It also makes it possible to perform the function of taking off the vehicle from zero speed, as well as having two gears with engine braking.
Ce dispositif permet également de réaliser des rapports de vitesse différents en utilisant les roues dentées de chaque voie de transmissions T1 ou T2 ou de combiner une partie des roues dentées de l'une T1 des voies avec une partie de l'autre T2 des voies pour réaliser d'autres rapports de vitesse. This device also makes it possible to achieve different speed ratios by using the gears of each transmission channel T1 or T2 or to combine a part of the gears of one T1 of the tracks with a part of the other T2 of the channels for perform other gear ratios.
Sur la figure 1 , les différentes roues de chaque voie de transmission de mouvement de rotation T1 et T2 sont reliées entre elles par une bande fermée sur elle-même, comme une chaîne ou une courroie, de préférence crantée intérieurement et/ou extérieurement. In Figure 1, the different wheels of each rotational movement transmission path T1 and T2 are connected together by a band closed on itself, such as a chain or a belt, preferably notched internally and / or externally.
Comme mieux visible sur cette figure, il est prévu une chaîne pour chaque voie de transmission, une chaîne 70 pour relier la grande roue dentée menante 1 6, la petite roue dentée intermédiaire 46 et la grande roue dentée menée 52, et une chaîne 68 pour relier la petite roue menante 14, la grande roue dentée intermédiaire 44 et la petite roue menée 50. Cela a pour effet de pouvoir modifier l'emplacement des arbres et de les placer à distance les uns des autres selon l'encombrement disponible tout en assurant la transmission du mouvement de rotation entre ces arbres. As best seen in this figure, there is provided a chain for each transmission channel, a chain 70 for connecting the large driving gear 1 6, the small intermediate gear 46 and the large driven gear 52, and a chain 68 for connecting the small driving wheel 14, the large intermediate gear wheel 44 and the small driven wheel 50. This has the effect of modifying the location of the trees and placing them at a distance from each other according to the available space while ensuring the transmission of the rotational movement between these trees.
De plus, cette chaîne (ou cette courroie) permet de limiter les frottements avec les roues en comparaison de la disposition selon laquelle les roues dentées engrènent directement les unes avec les autres. L'utilisation de chaîne ou de courroie peut permettre également d'éviter des solutions de lubrification en carter humide. In addition, this chain (or belt) limits the friction with the wheels compared to the arrangement according to which the gear wheels meshing directly with each other. The use of a chain or belt may also prevent wet sump lubrication solutions.
La variante de la figure 2 se distingue de l'exemple de réalisation de la figure 1 par le fait que l'embrayage à disque 18 pour la roue dentée menée 14 de l'arbre récepteur de la figure 1 est remplacé par un accouplement unidirectionnel 72, comme une roue libre, interposé entre la roue dentée 14 et l'arbre menant 12. Dans cette variante, la roue libre 66 interposée entre la grande roue dentée menée 52 et l'arbre récepteur 48 de la figure 1 est remplacé par un accouplement à commande contrôlée 74, ici sous la forme d'un embrayage à disque, coopérant avec un fourreau 76 portant la roue 52 en entourant l'arbre récepteur de manière fixe en translation mais libre en rotation. The variant of Figure 2 differs from the embodiment of Figure 1 in that the disc clutch 18 for the driven gear 14 of the receiving shaft of Figure 1 is replaced by a unidirectional coupling 72 , as a free wheel, interposed between the toothed wheel 14 and the drive shaft 12. In this variant, the free wheel 66 interposed between the large driven gear 52 and the receiving shaft 48 of FIG. 1 is replaced by a coupling controlled control 74, here in the form of a disk clutch, cooperating with a sleeve 76 carrying the wheel 52 by surrounding the receiving shaft in a fixed manner in translation but free in rotation.
Comme pour l'exemple de réalisation précédent, cet accouplement comporte un plateau de réaction 78 fixe sur l'arbre récepteur 48, un plateau de pression 80, libre en translation mais fixe en rotation avec le plateau de réaction, en étant commandé en déplacement vers le plateau de réaction par des leviers 82, et un disque de friction 84 libre en translation et fixe en rotation sur le fourreau 76 en étant placé entre le plateau de réaction et le plateau de pression. As for the preceding embodiment, this coupling comprises a reaction plate 78 fixed on the receiving shaft 48, a pressure plate 80, free in translation but fixed in rotation with the reaction plate, being controlled in motion towards the reaction plate by levers 82, and a friction disc 84 free in translation and fixed in rotation on the sleeve 76 being placed between the reaction plate and the pressure plate.
Le fonctionnement de cette variante est semblable à celui de la figure 1 en offrant la possibilité d'obtenir quatre rapports de vitesse. Pour l'un des rapports, les embrayages 20 et 56 sont en position débrayée et l'embrayage 74 est en position embrayée. Dans cette configuration, lors de la rotation de l'arbre moteur 12, la petite roue dentée menée 14 est entraînée en rotation par la mise en action de la roue libre 72 reliant l'arbre moteur et cette roue dentée. Cette rotation de la roue 14 est ensuite transmise à l'arbre intermédiaire 42 par la grande roue dentée intermédiaire 44, ce qui a pour effet d'entraîner en rotation la petite roue dentée intermédiaire 46. Cette petite roue entraîne à son tour la grande roue menée 52 qui retransmet cette rotation à l'arbre récepteur 48 sous l'action de l'embrayage 74. The operation of this variant is similar to that of Figure 1 by providing the possibility of obtaining four gear ratios. For one of the reports, the clutches 20 and 56 are in the disengaged position and the clutch 74 is in the engaged position. In this configuration, during the rotation of the motor shaft 12, the small driven gear 14 is rotated by the actuation of the freewheel 72 connecting the motor shaft and the toothed wheel. This rotation of the wheel 14 is then transmitted to the intermediate shaft 42 by the large intermediate gear wheel 44, which has the effect of rotating the small intermediate gear wheel 46. This small wheel in turn drives the ferris wheel led 52 which retransmits this rotation to the receiving shaft 48 under the action of the clutch 74.
Comme les deux embrayages 20 et 56 sont inactifs, ni la grande roue menante 1 6, ni la petite roue menée 50 ne sont entraînées en rotation par l'arbre moteur ou l'arbre récepteur, ces deux roues 1 6 et 50 tournent folles respectivement chacune autour de leur arbre respectif.  As the two clutches 20 and 56 are inactive, neither the large driving wheel 1 6, nor the small driven wheel 50 are driven in rotation by the drive shaft or the receiving shaft, these two wheels 1 6 and 50 turn crazy respectively each around their respective trees.
Dans un autre rapport, l'embrayage 20 et l'embrayage 74 sont en position embrayée et l'embrayage 56 est en position débrayée. La grande roue menante 1 6 est alors entraînée en rotation par l'arbre moteur 12 par l'action de l'embrayage 20. Cette rotation est retransmise à l'arbre intermédiaire 42 par la petite roue intermédiaire 46 qui la communique à la grande roue menée 52 La rotation de cette grande roue est transmise à l'arbre récepteur 48 au travers de l'embrayage 74.  In another report, the clutch 20 and the clutch 74 are in the engaged position and the clutch 56 is in the disengaged position. The large driving wheel 1 6 is then rotated by the drive shaft 12 by the action of the clutch 20. This rotation is transmitted to the intermediate shaft 42 by the small intermediate wheel 46 which communicates to the ferris wheel The rotation of this large wheel is transmitted to the receiver shaft 48 through the clutch 74.
Simultanément, la rotation de l'arbre intermédiaire 42 par la petite roue intermédiaire entraîne la rotation de la grande roue intermédiaire 44. Compte tenu du différentiel de vitesses de rotation entre l'arbre moteur 12 et la petite roue menante 14, cet arbre est désaccouplé de la petite roue menante par l'inaction de la roue libre 72. La petite roue menée 50 tourne alors folle autour de son axe sur l'arbre 48.  Simultaneously, the rotation of the intermediate shaft 42 by the small intermediate wheel causes the rotation of the large intermediate wheel 44. Given the differential speed of rotation between the drive shaft 12 and the small drive wheel 14, this shaft is uncoupled of the small driving wheel by the inaction of the freewheel 72. The small driven wheel 50 then turns wild about its axis on the shaft 48.
Dans un autre rapport de vitesse, l'embrayage 56 est en position embrayée et les embrayages 20 et 74 sont en position débrayée. La petite roue menée 14 est alors entraînée en rotation par la mise en action de la roue libre 72 reliant l'arbre moteur et cette roue dentée.  In another gear ratio, the clutch 56 is in the engaged position and the clutches 20 and 74 are in the disengaged position. The small driven wheel 14 is then rotated by the actuation of the freewheel 72 connecting the motor shaft and the toothed wheel.
La rotation de cette petite roue menante est communiquée à l'arbre intermédiaire 42 par la grande roue intermédiaire 44 qui la transmet à l'arbre récepteur par la petite roue menée 50 reliée à cet arbre récepteur par l'action de l'embrayage 56. The rotation of this small driving wheel is communicated to the intermediate shaft 42 by the large intermediate wheel 44 which transmits it to the shaft receiver by the small driven wheel 50 connected to this receiving shaft by the action of the clutch 56.
Bien entendu et cela compte tenu de la position débrayée des embrayages 20 et 74, la rotation de la petite roue intermédiaire 46 n'a aucune influence sur l'arbre menant 12 et sur l'arbre récepteur 48 puisque la grande roue dentée menante 1 6 et la grande roue dentée menée 52 tournent folles sur les arbres 12 et 48.  Of course, and in view of the disengaged position of the clutches 20 and 74, the rotation of the small intermediate wheel 46 has no influence on the driving shaft 12 and on the receiving shaft 48 since the large driving gear 1 6 and the large driven gear 52 turn wild on the 12th and 48th trees.
Pour le dernier rapport, les deux embrayages 20 et 56 sont en position embrayée et l'embrayage 74 est en position débrayée. La rotation de l'arbre moteur 12 est transmise, par l'action de l'embrayage 20, à la grande roue menante 1 6 qui la transmet à la petite roue dentée intermédiaire 46 de l'arbre intermédiaire 42 qui transmet cette rotation à la petite roue menée 50 par l'intermédiaire de la grande roue dentée intermédiaire 44. L'arbre récepteur est alors entraîné en rotation par l'action de l'embrayage 56 qui relie la petite roue dentée menée à cet arbre. For the last report, the two clutches 20 and 56 are in the engaged position and the clutch 74 is in the disengaged position. The rotation of the drive shaft 12 is transmitted, by the action of the clutch 20, to the large driving wheel 1 6 which transmits it to the small intermediate gear 46 of the intermediate shaft 42 which transmits this rotation to the small driven wheel 50 via the large intermediate gear wheel 44. The receiving shaft is then rotated by the action of the clutch 56 which connects the small gear wheel led to this shaft.
Dans cette configuration, la rotation de l'arbre intermédiaire 42 entraîne également, par l'entremise de la roue dentée intermédiaire 44, la rotation de la petite roue dentée menante 14. Comme déjà mentionnée, compte tenu du différentiel de vitesses de rotation entre la roue menante 14 et l'arbre moteur, ce dernier est désaccouplé de la petite roue menante 14 par la roue libre 72. La grande roue menée 52 tourne folle autour de son axe sur l'arbre 48.  In this configuration, the rotation of the intermediate shaft 42 also causes, through the intermediate gear 44, the rotation of the small driving gear 14. As already mentioned, given the difference in rotational speeds between the driving wheel 14 and the drive shaft, the latter is uncoupled from the small driving wheel 14 by the freewheel 72. The large driven wheel 52 turns wild about its axis on the shaft 48.
Pour la variante de la figure 3, la roue libre 66 de la figure 1 et la roue libre 72 de la figure 2 sont remplacées par un accouplement à commande contrôlée, comme un embrayage à disque 18 et 74. For the variant of FIG. 3, the freewheel 66 of FIG. 1 and the freewheel 72 of FIG. 2 are replaced by a controlled-control coupling, such as a disk clutch 18 and 74.
Ainsi, la petite roue dentée menante 14 est placée sur l'arbre moteur 12 sur un fourreau 22 entourant cet arbre en étant libre en rotation sur cet arbre mais fixe en translation et en ayant la possibilité d'être reliée en rotation à cet arbre par l'embrayage 18. La grande roue menée 52 est portée par un fourreau 76 entourant l'arbre récepteur 48 en étant libre en rotation sur cet arbre mais fixe en translation avec la possibilité d'être reliée en rotation à cet arbre par l'embrayage 74. Thus, the small drive gear 14 is placed on the drive shaft 12 on a sleeve 22 surrounding this shaft being free to rotate on the shaft but fixed in translation and having the possibility of being connected in rotation to this shaft by the clutch 18. The large driven wheel 52 is carried by a sleeve 76 surrounding the receiving shaft 48 while being free to rotate on this shaft but fixed in translation with the possibility of being connected in rotation to this shaft by the clutch 74.
Comme déjà illustré sur les figures 1 et 2, les embrayages 18 et 74 comprennent un plateau de réaction 26, 78 fixe sur l'arbre moteur 12 et l'arbre récepteur 48, un plateau de pression 30, 80, libre en translation mais fixe en rotation avec le plateau de réaction, en étant commandé en déplacement vers le plateau de réaction par tous moyens connus, comme des leviers 34, 82, et un disque de friction 38, 84 libre en translation sur les fourreaux 22, 76 mais fixe en rotation en étant placé entre le plateau de pression et le plateau de réaction. As already illustrated in Figures 1 and 2, the clutches 18 and 74 comprise a reaction plate 26, 78 fixed on the drive shaft 12 and the receiving shaft 48, a pressure plate 30, 80, free in translation but fixed in rotation with the reaction plate, being controlled in displacement towards the reaction plate by any known means, such as levers 34, 82, and a friction disc 38, 84 free in translation on the sleeves 22, 76 but fixed in rotation being placed between the pressure plate and the reaction plate.
Les rapports de vitesse sont semblables à ceux décrits ci-dessus avec, pour l'un des rapports, la position embrayée des embrayages 18 et 56 et la position débrayée des embrayages 20 et 74 ; pour un autre rapport de vitesse, la position embrayée des embrayages 20 et 74 et la position débrayée des embrayages 18 et 56 ; pour encore un autre rapport de vitesse, la position embrayée des embrayages 18 et 56 et la position débrayée des embrayages 20 et 74 ; pour un dernier rapport, la position embrayée des embrayages 20 et 56 et la position débrayée des embrayages 18 et 74. The gear ratios are similar to those described above with, for one of the reports, the engaged position of the clutches 18 and 56 and the disengaged position of the clutches 20 and 74; for another gear ratio, the engaged position of the clutches 20 and 74 and the disengaged position of the clutches 18 and 56; for yet another gear ratio, the engaged position of the clutches 18 and 56 and the disengaged position of the clutches 20 and 74; for a last report, the engaged position of the clutches 20 and 56 and the disengaged position of the clutches 18 and 74.
La figure 4 illustre maintenant l'application du dispositif de transmission de vitesse 10 à un groupe motopropulseur de véhicule automobile, notamment un véhicule à au moins deux roues. Figure 4 now illustrates the application of the speed transmission device 10 to a powertrain of a motor vehicle, including a vehicle with at least two wheels.
Ce groupe comprend donc un moteur de propulsion, ici un moteur à combustion interne 86, le dispositif de transmission de vitesse 10 et une voie motrice du véhicule. Comme visible sur cette figure, l'arbre moteur 12 du dispositif 10 est relié au vilebrequin 88 du moteur à combustion interne et l'arbre récepteur 48 est connecté à la voie motrice du véhicule (non représentée). A titre d'exemple, pour un véhicule à deux ou trois roues, cet arbre récepteur sera relié à la roue motrice (ou aux roues motrices) directement au travers d'une chaîne, d'une courroie ou d'un train d'engrenages ou indirectement par un essieu moteur portant les roues motrices. This group thus comprises a propulsion engine, here an internal combustion engine 86, the speed transmission device 10 and a driving path of the vehicle. As shown in this figure, the motor shaft 12 of the device 10 is connected to the crankshaft 88 of the internal combustion engine and the receiving shaft 48 is connected to the drive path of the vehicle (not shown). For example, for a vehicle with two or three wheels, this receiver shaft will be connected to the drive wheel (or the drive wheels) directly through a chain, a belt or a gear train or indirectly by a drive axle carrying the drive wheels.
Avantageusement, le groupe motopropulseur avec le dispositif de transmission de vitesse de la figure 4 peut être utilisé sur un véhicule de type hybride avec l'association d'une machine motrice/génératrice 90 au moteur à combustion interne 86. Advantageously, the powertrain with the speed transmission device of FIG. 4 can be used on a hybrid type vehicle with the combination of a prime mover / generator 90 to the internal combustion engine 86.
Cette machine est, uniquement à titre d'exemple dans la suite de la description, une machine hydraulique ou une machine électrique raccordée à des batteries (non représentées). Elle est utilisée, soit en tant que moteur électrique pour le déplacement du véhicule, soit en tant que génératrice pour charger les batteries ou alimenter les accessoires électriques du véhicule. This machine is, solely by way of example in the following description, a hydraulic machine or an electrical machine connected to batteries (not shown). It is used either as an electric motor for moving the vehicle, or as a generator to charge the batteries or power the vehicle's electrical accessories.
Comme mieux visible sur la figure 4, la machine électrique comporte un rotor 92 portant une roue dentée 94. Cette machine peut être reliée en différents endroits au dispositif de transmission. As best seen in Figure 4, the electric machine has a rotor 92 carrying a gear wheel 94. This machine can be connected in different places to the transmission device.
Ainsi, dans la configuration A mentionnée sur la figure 4, le rotor 92 est lié en rotation avec le plateau de réaction 78 de l'embrayage 74 ; pour la configuration B, ce rotor est relié à l'arbre intermédiaire 42 qui porte à cet effet une roue dentée de liaison fixe 96 ; pour la configuration C, le rotor est relié au plateau de réaction 28 de l'embrayage 20.  Thus, in the configuration A mentioned in FIG. 4, the rotor 92 is rotatably connected to the reaction plate 78 of the clutch 74; for configuration B, this rotor is connected to the intermediate shaft 42 which carries for this purpose a fixed link gear 96; for the configuration C, the rotor is connected to the reaction plate 28 of the clutch 20.
La localisation de cette machine sera choisie par l'homme du métier de manière judicieuse, notamment en tenant compte de l'encombrement et des rapports de vitesse souhaité pour l'entraînement purement électrique du véhicule. Dans la configuration A, la machine entraîne le véhicule avec un rapport de vitesse, pour la configuration B avec deux rapports de vitesse et pour la configuration C avec 4 rapports de vitesse. A titre d'exemple et comme mieux visible sur la figure 4, la liaison de la machine avec les plateaux de réaction ou avec la roue dentée de liaison 96 peut être réalisée par une chaîne ou une courroie crantée ou en prise directe. The location of this machine will be chosen by the skilled person in a judicious manner, including taking into account the size and speed ratios desired for the purely electric drive of the vehicle. In configuration A, the machine drives the vehicle with a gear ratio, for configuration B with two gear ratios and for configuration C with 4 gear ratios. For example and as best seen in Figure 4, the connection of the machine with the reaction plates or with the gear wheel 96 can be achieved by a chain or toothed belt or direct drive.
Cette liaison peut également être réalisée par coopération de la roue dentée 94 du rotor avec une denture complémentaire (non représentée) portée par la périphérie du plateau de réaction ou avec la denture de la roue dentée de liaison 96. This connection can also be achieved by co-operating the toothed wheel 94 of the rotor with a complementary toothing (not shown) carried by the periphery of the reaction plate or with the toothing of the toothed wheel 96.
Par cela, il est possible de réaliser l'entraînement du véhicule en marche avant ou en marche arrière grâce à la rotation du rotor 92 qui est transmise, via les différentes roues dentées, à la voie motrice. By this, it is possible to carry out the drive of the vehicle in forward or reverse through the rotation of the rotor 92 which is transmitted via the different gears to the drive way.
En fonctionnement purement électrique pour le déplacement du véhicule, seul le moteur électrique est utilisé. En outre, ce moteur électrique peut être également utilisé en association avec le moteur à combustion interne 86, soit pour amener un complément de puissance sur l'arbre récepteur, soit être utilisé en tant que génératrice pour recharger les batteries. In purely electric operation for the movement of the vehicle, only the electric motor is used. In addition, this electric motor can also be used in combination with the internal combustion engine 86, either to bring additional power to the receiver shaft, or be used as a generator to recharge the batteries.
De plus, lors des décélérations du véhicule, le rotor de la machine est entraîné en rotation par les différentes roues dentées et dans ce cas la machine devient une génératrice. In addition, during decelerations of the vehicle, the rotor of the machine is rotated by the different gears and in this case the machine becomes a generator.
