Abstract

The system includes a primary gear train (XX') driving a secondary gear train (YY') using a gear unit (5), this movement being transmitted to the differential (9). The primary train includes a principal shaft (3) driven by an IC engine (1) and a tubular auxiliary shaft (4), which is driven by an electric motor (2). By means of a sliding gear (42) fixed to the principal shaft, it is possible to directly engage the auxiliary shaft or obtain speed reduction by using intermediate reduction gears (40-60, 61-41).

Description

La présente invention concerne un système de transmission de mouvement pour un véhicule à propulsion hybride. The present invention relates to a motion transmission system for a hybrid propulsion vehicle.

Par l'expression propulsion hybride , on entendra dans la présente description, et dans les revendications qui suivent, 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. By the expression hybrid propulsion will be understood in the present description, and in the claims which follow, a propulsion which is produced from a heat engine and / or an electric motor, the vehicle being equipped with these two types engine.

Le système de transmission qui fait l'objet de l'invention est du type comportant des lignes primaire et secondaire parallèles, à savoir une ligne primaire motrice et une ligne secondaire réceptrice du mouvement, laquelle entraîne un différentiel qui commande à son tour les roues motrices du véhicule. The transmission system which is the subject of the invention is of the type comprising parallel primary and secondary lines, namely a primary drive line and a secondary line receiving the movement, which drives a differential which in turn controls the drive wheels. of the vehicle.

L'objectif de l'invention est de proposer un système de transmission du type ci-dessus indiqué, qui soit d'une conception relativement simple et compacte, et qui permette de développer un couple adapté aux conditions de circulation du véhicule, en particulier à la vitesse voulue, ceci en utilisant comme source motrice l'un et/ou l'autre des deux moteurs. The objective of the invention is to propose a transmission system of the type indicated above, which is of a relatively simple and compact design, and which makes it possible to develop a torque adapted to the conditions of circulation of the vehicle, in particular to the desired speed, this using one and / or the other of the two motors as the driving source.

Cet objectif est atteint, conformément à l'invention, grâce au fait que - la ligne primaire est constituée d'un arbre menant principal entraîné en rotation par le moteur thermique via un embrayage et d'un arbre menant auxiliaire tubulaire qui entoure coaxialement l'arbre menant principal et qui est entraîné par le moteur électrique, ces deux arbres étant mutuellement libres en rotation ; - l'arbre menant principal porte un pignon fou ; - l'arbre menant auxiliaire porte un pignon, dont il est solidaire en rotation, et dont le diamètre est différent dudit pignon fou ; - elle comporte une ligne tertiaire qui est parallèle aux lignes primaire et secondaire et est constituée par un arbre - dit intermédiaire - libre en rotation ; - l'arbre intermédiaire porte une paire de pignons de diamètres différents, dont il est solidaire en rotation, l'un de ces pignons étant en prise avec le pignon de l'arbre menant auxiliaire, tandis que l'autre est en prise avec le pignon fou de l'arbre menant principal ; - un baladeur permet de solidariser sélectivement, soit ledit pignon de l'arbre menant auxiliaire, soit ledit pignon fou, avec l'arbre menant principal. L'invention est particulièrement adaptée à un système de transmission du type mentionné ci-dessus, dans lequel la ligne secondaire comporte un arbre mené qui est entraîné par l'arbre menant principal au moyen d'un variateur de vitesse. This objective is achieved, in accordance with the invention, thanks to the fact that - the primary line consists of a main driving shaft driven in rotation by the heat engine via a clutch and of a tubular auxiliary driving shaft which coaxially surrounds the main drive shaft which is driven by the electric motor, these two shafts being mutually free to rotate; - the main drive shaft carries an idler gear; - The auxiliary drive shaft carries a pinion, of which it is integral in rotation, and whose diameter is different from said idler pinion; - It includes a tertiary line which is parallel to the primary and secondary lines and is constituted by a shaft - called intermediate - free to rotate; the intermediate shaft carries a pair of pinions of different diameters, of which it is integral in rotation, one of these pinions being engaged with the pinion of the auxiliary driving shaft, while the other is engaged with the idler gear of the main drive tree; - A player selectively secures either said pinion of the auxiliary drive shaft, or said idler gear, with the main drive shaft. The invention is particularly suitable for a transmission system of the type mentioned above, in which the secondary line comprises a driven shaft which is driven by the main driving shaft by means of a variable speed drive.

De manière usuelle, un variateur de vitesse comporte une paire de poulies, et la poulie secondaire possède un dispositif de commande relativement encombrant dans le sens de la longueur. Usually, a variable speed drive has a pair of pulleys, and the secondary pulley has a relatively bulky control device in the longitudinal direction.

Il est possible de donner au dispositif une configuration telle que la longueur de l'arbre intermédiaire s'inscrive dans cet encombrement, ce qui permet d'obtenir, globalement, une compacité remarquable. It is possible to give the device a configuration such that the length of the intermediate shaft fits into this space, which makes it possible to obtain, overall, a remarkable compactness.

Selon un mode de réalisation possible, l'arbre mené entraîne le différentiel par l'intermédiaire d'un mécanisme de démultiplication de vitesse. D'autres caractéristiques et avantages de l'invention apparaîtront de la description qui va suivre, en référence aux dessins annexés, qui représentent un mode de réalisation préféré de l'objet de cette invention. According to a possible embodiment, the driven shaft drives the differential by means of a gear reduction mechanism. Other characteristics and advantages of the invention will emerge from the description which follows, with reference to the appended drawings, which represent a preferred embodiment of the subject of this invention.

Sur les dessins - la figure 1 est une vue générale, très schématique, d'un mode de réalisation possible du système de transmission ; - les figures 2 et 3 sont des vues partielles, analogues à la vue de la figure 1, destinées à montrer deux modes d'entraînement possibles de l'arbre principal à partir du moteur électrique ; sur ces deux figures, les différents organes d'entraînement qui ne sont pas sollicités dans la configuration illustrée n'ont pas été représentés, afin de ne pas alourdir inutilement les figures. In the drawings - Figure 1 is a general view, very schematic, of a possible embodiment of the transmission system; - Figures 2 and 3 are partial views, similar to the view of Figure 1, intended to show two possible drive modes of the main shaft from the electric motor; in these two figures, the various drive members which are not stressed in the illustrated configuration have not been shown, so as not to unnecessarily burden the figures.

Sur la figure 1, on a désigné par les références XX' et YY' les lignes primaire et, respectivement, secondaire du système de transmission. In FIG. 1, the primary and, respectively, secondary lines of the transmission system have been designated by the references XX 'and YY'.

Ces deux lignes sont parallèles, disposées à proximité l'une de l'autre. Dans l'exemple illustré, la ligne XX est placée au-dessus de la ligne YY'. These two lines are parallel, arranged close to each other. In the example illustrated, line XX is placed above line YY '.

Le moteur thermique, qui est par exemple un moteur à quatre temps, à essence ou du type Diesel, est référencé 1. The heat engine, which is for example a four-stroke engine, petrol or of the Diesel type, is referenced 1.

Le moteur électrique est référencé 2, son stator (central) et son rotor (annulaire) étant référencés respectivement 20 et 21. The electric motor is referenced 2, its stator (central) and its rotor (annular) being referenced 20 and 21 respectively.

La ligne primaire XX' est constituée d'une paire d'arbres, dits menants, à savoir un arbre principal 3 et un arbre auxiliaire tubulaire 4. The primary line XX ′ is made up of a pair of shafts, called leading shafts, namely a main shaft 3 and a tubular auxiliary shaft 4.

L'arbre 3 est entraîné en rotation par le moteur thermique 1, ceci par l'intermédiaire d'un embrayage 10 de type connu. Dans sa portion d'extrémité qui est opposée à l'extrémité comportant l'embrayage 10, cet arbre 3 entraîne un variateur de vitesse, qui sera décrit plus loin. The shaft 3 is rotated by the heat engine 1, this by means of a clutch 10 of known type. In its end portion which is opposite the end comprising the clutch 10, this shaft 3 drives a speed variator, which will be described later.

L'axe du moteur électrique 2 coïncide avec la ligne XX', le rotor 21 entourant le stator 20 qui lui-même entoure coaxialement l'arbre 3 qui le traverse. Avantageusement, le stator 20 est solidaire d'une partie fixe 200 constitutive du carter de l'embrayage 10. The axis of the electric motor 2 coincides with the line XX ', the rotor 21 surrounding the stator 20 which itself coaxially surrounds the shaft 3 which passes through it. Advantageously, the stator 20 is integral with a fixed part 200 constituting the clutch housing 10.

Le moteur électrique est donc contenu dans ce carter. The electric motor is therefore contained in this casing.

L'arbre creux auxiliaire 4 est traversé par l'arbre principal 3 et est libre en rotation par rapport à ce dernier. The auxiliary hollow shaft 4 is traversed by the main shaft 3 and is free to rotate relative to the latter.

L'arbre 4 est notablement plus court que l'arbre 3, celui-ci dépassant largement à ses deux extrémités, d'un côté par la portion équipée de l'embrayage 10, de l'autre jusqu'au variateur 5. The shaft 4 is notably shorter than the shaft 3, the latter largely protruding at its two ends, on one side by the portion equipped with the clutch 10, on the other to the variator 5.

L'arbre tubulaire 4 est solidaire à l'une de ses extrémités du rotor 21. Dans sa portion d'extrémité opposée, il porte un pignon 40. The tubular shaft 4 is integral with one of its ends of the rotor 21. In its opposite end portion, it carries a pinion 40.

Sur l'arbre 3, entre le pignon 40 et le variateur 5, est monté un pignon fou 41. On the shaft 3, between the pinion 40 and the variator 5, is mounted a idler pinion 41.

Un baladeur 42 intercalé entre les pignons 40 et 41, et solidaire en rotation de l'arbre 3, permet de solidariser sélectivement avec ce dernier, soit le pignon 40, soit le pignon 41. A player 42 interposed between the pinions 40 and 41, and integral in rotation with the shaft 3, makes it possible to selectively secure with the latter, either the pinion 40, or the pinion 41.

Des organes appropriés, tels que des paliers de roulement référencés 300, 301 et 400, assurent le guidage en rotation des deux arbres 3, 4 de la ligne primaire. Appropriate members, such as rolling bearings referenced 300, 301 and 400, ensure the rotational guidance of the two shafts 3, 4 of the primary line.

Dans l'exemple illustré, le palier 300 réalise le guidage d'une extrémité de l'arbre 3, du côté opposé à l'embrayage, tandis que le palier 400 assure le guidage de l'arbre tubulaire 4 dans sa portion comprise entre le moteur 2 et la paire de pignons 40, 41. Le palier 301 assure un guidage intermédiaire de l'arbre 3, entre le variateur 5 et le pignon 41. In the example illustrated, the bearing 300 guides one end of the shaft 3, on the side opposite to the clutch, while the bearing 400 guides the tubular shaft 4 in its portion between the motor 2 and the pair of pinions 40, 41. The bearing 301 provides intermediate guiding of the shaft 3, between the variator 5 and the pinion 41.

L'arbre 4 est lui-même guidé en rotation sur l'arbre central 3, si bien que les deux arbres 3, 4 sont parfaitement guidés en rotation. The shaft 4 is itself guided in rotation on the central shaft 3, so that the two shafts 3, 4 are perfectly guided in rotation.

Des moyens appropriés, non représentés, assurent également l'immobilisation axiale de chacun de ces deux arbres. Appropriate means, not shown, also ensure the axial immobilization of each of these two shafts.

La ligne secondaire YY' comporte un arbre mené 7, guidé en rotation dans des paliers 700, 701 à ses deux extrémités, et convenablement immobilisé en translation. Le variateur 5 assure une démultiplication automatique et continue, en fonction de la vitesse, dans la transmission du mouvement de l'arbre menant 3 à l'arbre mené 7. The secondary line YY 'comprises a driven shaft 7, guided in rotation in bearings 700, 701 at its two ends, and suitably immobilized in translation. The variator 5 ensures an automatic and continuous reduction, as a function of the speed, in the transmission of the movement of the driving shaft 3 to the driven shaft 7.

Ce variateur est de type connu en soi. This variator is of a type known per se.

Il comprend une paire de poulies menante 50 et menée 51 portées par les arbres 3 et, respectivement, 7. It includes a pair of driving pulleys 50 and driven 51 carried by the shafts 3 and, respectively, 7.

Les poulies sont des poulies à gorge biconique, dont l'un des flasques est mobile latéralement par rapport à l'autre, de sorte que la largeur de sa gorge varie avec la vitesse. The pulleys are pulleys with biconical grooves, one of the flanges of which is movable laterally with respect to the other, so that the width of its groove varies with speed.

Lorsque la vitesse augmente, la largeur de gorge de la poulie motrice 50 diminue tandis que celle de la poulie réceptrice 51 augmente d'une valeur correspondante, et inversement. When the speed increases, the groove width of the driving pulley 50 decreases while that of the receiving pulley 51 increases by a corresponding value, and vice versa.

Une courroie de section trapézoïdale 52 assure la transmission du mouvement entre les deux poulies, avec un facteur de démultiplication qui varie donc de façon automatique et continue. A trapezoidal section belt 52 ensures the transmission of movement between the two pulleys, with a reduction factor which therefore varies automatically and continuously.

Chaque poulie 50, 51 comporte un mécanisme de commande relativement sophistiqué, par exemple à ressorts et masselottes, qui provoque l'écartement ou le rapprochement mutuel des deux flasques en fonction de la vitesse de rotation. Ces mécanismes sont logés dans des boîtiers 53, respectivement 54, relativement volumineux et encombrants dans le sens de la longueur (suivant l'axe de la ligne). Each pulley 50, 51 comprises a relatively sophisticated control mechanism, for example with springs and weights, which causes the spacing or mutual approximation of the two flanges as a function of the speed of rotation. These mechanisms are housed in housings 53, respectively 54, relatively bulky and bulky in the longitudinal direction (along the axis of the line).

C'est le cas, en particulier, pour le boîtier 54 de la poulie réceptrice 51. This is the case, in particular, for the housing 54 of the receiving pulley 51.

L'arbre mené 7 porte un pignon 70, dont il est solidaire en rotation. Ce pignon est en prise avec un pignon 80 constitutif d'un mécanisme de démultiplication comprenant un arbre 8, parallèle à l'arbre 7, et portant - outre le pignon 80 - un second pignon 81. L'arbre 8 est libre en rotation. Il est guidé en rotation, par ses portions d'extrémité, dans des paliers appropriés 800, 801. The driven shaft 7 carries a pinion 70, of which it is integral in rotation. This pinion is engaged with a pinion 80 constituting a reduction mechanism comprising a shaft 8, parallel to the shaft 7, and carrying - in addition to the pinion 80 - a second pinion 81. The shaft 8 is free to rotate. It is guided in rotation, by its end portions, in appropriate bearings 800, 801.

Les pignons 80, 81 ont des diamètres différents. The pinions 80, 81 have different diameters.

Le pignon 81 est en prise avec la couronne 90 du différentiel 9. The pinion 81 is engaged with the crown 90 of the differential 9.

De manière connue, celui-ci entraîne deux demi-essieux 91a, 91b, qui portent chacun l'une des roues motrices du véhicule. In known manner, this drives two half-axles 91a, 91b, which each carry one of the drive wheels of the vehicle.

Selon une caractéristique essentielle, le système qui fait l'objet de la présente invention est équipé d'un arbre intermédiaire 6, qui matérialise une ligne WW', dite "tertiaire". L'arbre 6 est parallèle aux arbres 3 et 7, et est disposé entre ces deux derniers. Il est guidé, à chaque extrémité, dans des paliers appropriés 600, 601, et immobilisé en translation. According to an essential characteristic, the system which is the subject of the present invention is equipped with an intermediate shaft 6, which materializes a line WW ', called "tertiary". The shaft 6 is parallel to the trees 3 and 7, and is arranged between the latter two. It is guided, at each end, in appropriate bearings 600, 601, and immobilized in translation.

Cet arbre 6 porte une paire de pignons 60, 61 dont il est solidaire en rotation. This shaft 6 carries a pair of pinions 60, 61 of which it is integral in rotation.

L'écartement mutuel des deux pignons 60, 61 est identique à celui des deux pignons précités 40, 41.  The mutual spacing of the two pinions 60, 61 is identical to that of the above two pinions 40, 41.

Leurs diamètres sont tels que le pignon 60 vient en prise avec le pignon 40, et le pignon 61 avec le pignon 41. Their diameters are such that the pinion 60 engages with the pinion 40, and the pinion 61 with the pinion 41.

Bien entendu, la somme des rayons de deux pignons en prise correspond par conséquent à la valeur d'entraxe des deux lignes XX', `VW'. Of course, the sum of the radii of two gears in engagement therefore corresponds to the value of spacing of the two lines XX ', `VW'.

Les deux jeux de pignons 40-4l, 60-6l, constituent le mécanisme d'une boîte de vitesses à deux vitesses pour le mode d'entraînement électrique, comme cela va être expliqué ci-après. The two sets of pinions 40-4l, 60-6l, constitute the mechanism of a two-speed gearbox for the electric drive mode, as will be explained below.

En mode de fonctionnement thermique, le moteur 1 entraîne l'arbre 3 lorsque l'embrayage 10 est en position embrayée. In thermal operating mode, the motor 1 drives the shaft 3 when the clutch 10 is in the engaged position.

Cette rotation est transmise à l'arbre 7 par l'intermédiaire du variateur 5, avec un rapport de démultiplication automatiquement variable, dépendant de la vitesse. This rotation is transmitted to the shaft 7 via the variator 5, with an automatically variable gear ratio, dependent on the speed.

A son tour, l'arbre 7 transmet ce mouvement, via les pignons 70-80 et 81 à la couronne 90 du différentiel, avec un rapport de démultiplication déterminé. Les demi-essieux 91 a, 91 b sont ainsi entraînés en rotation. In turn, the shaft 7 transmits this movement, via the pinions 70-80 and 81 to the crown 90 of the differential, with a determined gear ratio. The half-axles 91 a, 91 b are thus driven in rotation.

En mode de fonctionnement électrique, en première vitesse, le baladeur 42 est craboté sur le pignon 40. In electric operating mode, in first gear, the sliding gear 42 is clutched to the pinion 40.

Cette situation est illustrée sur la figure 2. This situation is illustrated in Figure 2.

Le rotor 21 entraîne l'arbre tubulaire 4 et le pignon 40 en rotation, comme symbolisé par la flèche f,. The rotor 21 drives the tubular shaft 4 and the pinion 40 in rotation, as symbolized by the arrow f i.

Ce mouvement est transmis à l'arbre central 3 par l'intermédiaire du baladeur 42, comme symbolisé par la flèche g,. This movement is transmitted to the central shaft 3 via the player 42, as symbolized by the arrow g i.

Ce mouvement est ensuite transmis au différentiel via le variateur 5, de la même façon qu'en fonctionnement thermique. This movement is then transmitted to the differential via the variator 5, in the same way as in thermal operation.

Le moteur électrique 2 se trouve donc en prise directe avec le variateur 5. The electric motor 2 is therefore in direct contact with the variator 5.

Les pignons 60, 61 et 41 tournent librement, leur mouvement n'ayant pas d'influence sur la propulsion. Toujours en mode de fonctionnement électrique, mais en seconde vitesse, le baladeur 42 est cette fois craboté sur le pignon 41. The pinions 60, 61 and 41 rotate freely, their movement having no influence on the propulsion. Still in electric operating mode, but in second gear, the player 42 is this time clutched to the pinion 41.

Cette situation est illustrée sur la figure 3. This situation is illustrated in Figure 3.

Le rotor 21 entraîne l'arbre tubulaire 4 et le pignon 40 en rotation, comme symbolisé par la flèche f2. The rotor 21 drives the tubular shaft 4 and the pinion 40 in rotation, as symbolized by the arrow f2.

Le pignon 40 entraîne, en sens inverse, le pignon 60 et, conjointement, l'arbre 6 et le pignon 61 (flèches g2). The pinion 40 drives, in the opposite direction, the pinion 60 and, jointly, the shaft 6 and the pinion 61 (arrows g2).

A son tour, le pignon 61 entraîne le pignon 41 en sens inverse de 92, symbolisé par la flèche h2. In turn, the pinion 61 drives the pinion 41 in the opposite direction to 92, symbolized by the arrow h2.

Ce mouvement est transmis à l'arbre 3 par l'intermédiaire du baladeur 42. This movement is transmitted to the shaft 3 via the player 42.

L'arbre 3 tourne donc selon h2, dans le même sens, mais à vitesse différente - en l'occurrence supérieure - à f2, en raison de la démultiplication liée aux différences de diamètres des deux jeux de pignons 40-60 et 61-4I. The shaft 3 therefore rotates according to h2, in the same direction, but at a different speed - in this case greater - than f2, due to the reduction linked to the differences in diameters of the two sets of pinions 40-60 and 61-4I .

Ce mouvement est transmis au différentiel via le variateur 5, comme dans les configurations précédentes. This movement is transmitted to the differential via the variator 5, as in the previous configurations.

Il est possible, bien sûr, de mettre en fonctionnement, simultanément, à la fois le moteur thermique et le moteur électrique (soit en première, soit en seconde vitesse) de telle sorte que les couples qu'ils développent s'ajoutent. It is possible, of course, to simultaneously operate both the heat engine and the electric motor (either first or second speed) so that the torques they develop are added.

Le moteur électrique peut servir d'appoint au moteur thermique à toute demande de puissance importante. The electric motor can be used as a supplement to the heat engine for any significant power demand.

Il peut être utilisé seul au démarrage et/ou au moment de l'arrêt, voire à faible vitesse. It can be used alone at start-up and / or at stop, or even at low speed.

On peut faire le choix que la seconde vitesse électrique soit plus longue ou plus courte que la ligne directe. You can choose whether the second electric speed is longer or shorter than the direct line.

Le moteur électrique peut donc avoir ainsi une vitesse de rotation maximale inférieure ou supérieure à celle du moteur thermique. The electric motor can thus have a maximum rotation speed lower or higher than that of the thermal engine.

Dans un souci de bonne lisibilité des dessins, les différents pignons et paliers ont été représentés avec des espacements importants selon la direction longitudinale (suivant XX', WW' et YY'). For the sake of readability of the drawings, the various gears and bearings have been shown with large spacings in the longitudinal direction (along XX ', WW' and YY ').

En pratique, ils sont plus rapprochés. In practice, they are closer together.

Ainsi, le système peut être agencé de telle sorte que l'arbre auxiliaire 6 et ses pignons 60-6l viennent se positionner en vis-à-vis du boîtier de commande 54 de la poulie réceptrice 51, de manière à s'inscrire dans son encombrement, relativement important. On obtient ainsi un ensemble extrêmement compact.Thus, the system can be arranged in such a way that the auxiliary shaft 6 and its pinions 60-6l come to be positioned facing the control unit 54 of the take-up pulley 51, so as to register in its size, relatively large. An extremely compact assembly is thus obtained.
