Description

SYSTEME DE TRANSMISSION A COUPLAGE/DECOUPLAGE DE MACHINES ELECTRIQUES, ROUE, VEHICULE ET SUR LA BASE D’UN TEL SYSTEMECOUPLING/DECOUPLING TRANSMISSION SYSTEM OF ELECTRIC MACHINES, WHEELS, VEHICLES AND ON THE BASIS OF SUCH A SYSTEM

L’invention se rapporte au domaine des dispositifs et systèmes de transmission pour véhicule hybride thermique/électrique. L’invention concerne plus particulièrement des moyens de transmission entre un moteur thermique et au moins deux machines électriques concentriques.The invention relates to the field of transmission devices and systems for thermal/electric hybrid vehicles. The invention relates more particularly to means of transmission between a heat engine and at least two concentric electric machines.

L’invention trouve une application particulière dans la transmission entre un moteur thermique et une roue incluant des machines électriques. Il s’agit d’un organe de transmission entre le moteur thermique et la roue incluant des moteurs électriques.The invention finds a particular application in the transmission between a heat engine and a wheel including electric machines. This is a transmission component between the heat engine and the wheel including electric motors.

Dans ce domaine il a été proposé des systèmes de transmissions basées sur des coupleurs magnétiques pour simplifier l’assemblage. Malheureusement, les solutions proposées ne sont pas pleinement satisfaisantes du point de vue de la taille de l’assemblage obtenu et du rendement.In this field, transmission systems based on magnetic couplers have been proposed to simplify assembly. Unfortunately, the proposed solutions are not fully satisfactory from the point of view of the size of the assembly obtained and the yield.

En effet, les solutions de l’état de l’art proposent des configurations fixes aboutissant à des rendements de coupleur bas.Indeed, state-of-the-art solutions offer fixed configurations resulting in low coupler efficiencies.

Ainsi, un objectif de l’invention est de proposer une solution de coupleur magnétique permettant d’avoir un changement de configurations de sorte à s’adapter à différentes situations et d’augmenter le rendement du coupleur.Thus, an objective of the invention is to propose a magnetic coupler solution making it possible to have a change of configurations so as to adapt to different situations and to increase the efficiency of the coupler.

Pour atteindre cet objectif, l’invention propose un système de transmission pour véhicule automobile, le système de transmission comprenant
- au moins deux machines électriques concentriques disposées sensiblement à l’intérieur d’une roue de véhicule,
- un arbre de transmission s’étendant suivant un axe central des machines électriques,
caractérisé en ce qu’il comprend un système de couplage/découplage des machines électriques, et/ou d’au moins une machine électrique à un bâti fixe.To achieve this objective, the invention proposes a transmission system for a motor vehicle, the transmission system comprising
- at least two concentric electrical machines arranged substantially inside a vehicle wheel,
- a transmission shaft extending along a central axis of the electrical machines,
characterized in that it comprises a system for coupling/decoupling electric machines, and/or at least one electric machine to a fixed frame.

Avantageusement, le système de couplage permet un changement de configuration permettant dans une deuxième configuration de combiner les deux machines électriques, dans une troisième configuration d’immobiliser une machine électrique.Advantageously, the coupling system allows a change of configuration allowing in a second configuration to combine the two electric machines, in a third configuration to immobilize an electric machine.

Selon une variante, le système de couplage/découplage comprend un mécanisme de crabotage. Cela permet de coupler facilement la machine électrique à une pièce adjacente.According to a variant, the coupling/decoupling system comprises a dog clutch mechanism. This makes it easy to couple the electric machine to an adjacent room.

Selon une variante, le système de couplage/découplage est configuré pour être déplacé entre les machines pour les coupler entre-elles. Cela permet de coupler simplement les deux machines électriques.According to a variant, the coupling/decoupling system is configured to be moved between the machines to couple them together. This makes it possible to simply couple the two electric machines.

Selon une variante, le système de couplage/découplage est configuré pour être déplacé d’une machine vers le bâti fixe pour immobiliser ladite machine. Cela permet de coupler simplement la machine électrique au bâti fixe.According to a variant, the coupling/decoupling system is configured to be moved from a machine to the fixed frame to immobilize said machine. This makes it possible to simply couple the electric machine to the fixed frame.

Selon une variante, le système de couplage/découplage est piloté par actionnement électromagnétique. Cela permet d’actionner le couplage avec une force significative.According to a variant, the coupling/decoupling system is controlled by electromagnetic actuation. This allows the coupling to be operated with significant force.

Selon une variante, le système de couplage/découplage comprend un moyen de glissement à embrayage.According to a variant, the coupling/decoupling system comprises a sliding clutch means.

Selon une variante, au moins une machine électrique est une machine axiale ou radiale ou une combinaison radiale/axiale.According to a variant, at least one electric machine is an axial or radial machine or a radial/axial combination.

L’invention concerne également une roue de véhicule comprenant un système de transmission selon l’invention.The invention also relates to a vehicle wheel comprising a transmission system according to the invention.

Un autre objet de l’invention concerne un véhicule automobile comprenant un système de transmission selon l’invention.Another object of the invention relates to a motor vehicle comprising a transmission system according to the invention.

L’invention concerne également une méthode de roulage d’un véhicule automobile comprenant un système de transmission selon l’invention, la méthode comprenant des étapes pour
- coupler les machines lors de phases en dérivation de puissance ; et/ou
- découpler les deux machines lors des phases de roulage électrique ; et/ou

Pour plus de clarté, les hachures de coupe sont omises dans la . On distingue un stator dit « fixe » SF (servant de machine électrique par exemple de traction), et un rotor ST (ou stator tournant) pouvant servir de coupleur magnétique ou de deuxième machine électrique. S’agissant d’un coupleur magnétique, le stator SF habituellement fixe est tournant.The transmission system T comprises two concentric electric machines (or electric motors) arranged substantially inside a vehicle wheel R. These machines are illustrated in . For clarity, section hatches are omitted from the . A distinction is made between a so-called “fixed” stator SF (serving as an electric machine for example for traction), and a rotor ST (or rotating stator) which can serve as a magnetic coupler or as a second electric machine. Being a magnetic coupler, the usually fixed stator SF is rotating.

Le système de transmission T comprend en outre un arbre de transmission A s’étendant suivant un axe central des machines électriques SF, ST. Une première section de l’arbre A (à droite sur la ) se trouve dans l’axe central du rotor ST. Une deuxième section (à gauche sur la ) se trouve dans l’axe central du stator SF.The transmission system T further comprises a transmission shaft A extending along a central axis of the electric machines SF, ST. A first section of tree A (on the right on the ) is in the central axis of the rotor ST. A second section (on the left on the ) is in the central axis of the stator SF.

Le système de transmission T comprend de préférence en outre des balais collecteurs B en contact avec l’arbre de transmission A.The transmission system T preferably further comprises commutator brushes B in contact with the transmission shaft A.

Les balais collecteurs B sont de préférence intégrés à ladite machine électrique SF, ST. En outre, les balais collecteurs B sont de préférence orientés dans un sens radial vis-à-vis de l’arbre de transmission A.The collector brushes B are preferably integrated into said electric machine SF, ST. Furthermore, the commutator brushes B are preferably oriented in a radial direction with respect to the transmission shaft A.

Selon l’invention, le système de transmission T comprend un système de couplage/découplage soit des machines électriques SF, ST entre-elles, soit d’au moins une machine électrique ST à un bâti fixe, à savoir un carter fixe CF.According to the invention, the transmission system T comprises a system for coupling/decoupling either electric machines SF, ST between them, or at least one electric machine ST to a fixed frame, namely a fixed casing CF.

Avantageusement, le système de couplage implique un changement de configuration permettant dans une deuxième configuration de combiner les deux machines électriques SF, ST, dans une troisième configuration d’immobiliser une machine électrique ST.Advantageously, the coupling system involves a change of configuration allowing in a second configuration to combine the two electric machines SF, ST, in a third configuration to immobilize an electric machine ST.

En particulier, le système de couplage/découplage comprend un mécanisme de crabotage CR vis-à-vis d’au moins une des machines électriques ST, configuré pour un déplacement axial suivant l’axe des machines électriques SF, ST.In particular, the coupling/decoupling system comprises a dog clutch mechanism CR vis-à-vis at least one of the electric machines ST, configured for an axial displacement along the axis of the electric machines SF, ST.

Le mécanisme de crabotage CR est de préférence externe aux machines électriques pour avoir une bonne tenue.The dog clutch mechanism CR is preferably external to the electric machines in order to have good resistance.

Dans la variante illustrée, le système de couplage/découplage, à savoir le mécanisme de crabotage CR, est sur une machine, à savoir le coupleur ST. En outre, ce système de couplage/découplage est configuré pour être déplacé vers l’autre machine électrique, à savoir le stator SF, pour coupler les deux machines ensemble SF, ST.In the variant illustrated, the coupling/decoupling system, namely the dog clutch mechanism CR, is on a machine, namely the coupler ST. Furthermore, this coupling/decoupling system is configured to be moved to the other electric machine, namely the stator SF, to couple the two machines together SF, ST.

Par ailleurs, dans la variante illustrée, le système de couplage/découplage, à savoir le mécanisme de crabotage CR, est configuré pour être déplacé vers le carter fixe CF pour immobiliser ladite machine, à savoir le coupleur ST.Furthermore, in the variant illustrated, the coupling/decoupling system, namely the dog clutch mechanism CR, is configured to be moved towards the fixed casing CF to immobilize said machine, namely the coupler ST.

Ainsi, le coupleur ST est de préférence disposé entre l’autre machine électrique SF et le carter fixe CF. Cela permet de déplacer le système de couplage d’un côté ou de l’autre selon les besoins.Thus, the coupler ST is preferably arranged between the other electrical machine SF and the fixed casing CF. This allows the coupling system to be moved to one side or the other as needed.

L’invention permet lors de certaines phases de vie d’effacer complètement une machine électrique ST (le coupleur). Elle permet aussi de bloquer en rotation le rotor coupleur ST afin qu’il fonctionnement non plus en coupleur mais en machine électrique traditionnelle.The invention makes it possible during certain phases of life to completely erase an electrical machine ST (the coupler). It also makes it possible to lock the ST coupler rotor in rotation so that it no longer operates as a coupler but as a traditional electric machine.

Il est aussi intéressant dans certaines configurations (par exemple en extension de jauge, en hybride « Plugin » (ou PHEV) ou en hybride de série) de séparer le coupleur magnétique ST de la machine de traction SF car cela permet en Zone de Traction Electrique Pure de ne plus avoir les pertes du coupleur ST. En outre, cela permet en extension de jauge, de bloquer le coupleur ST pour créer un « hybride série ».It is also interesting in certain configurations (for example in extension of gauge, in hybrid "Plugin" (or PHEV) or in hybrid of series) to separate the magnetic coupler ST from the traction machine SF because that allows in Electric Traction Zone Pure to no longer have the losses of the ST coupler. In addition, this allows gauge extension to block the ST coupler to create a "series hybrid".

La illustre un système décraboté entre les machines électriques ST, SF permettant de faire fonctionner le système en véhicule électrique à batterie (BEV).The illustrates a clutch-free system between the electric machines ST, SF allowing the system to operate as a battery electric vehicle (BEV).

La illustre un système craboté entre les machines électriques ST, SF permettant de faire fonctionner le système en véhicule hybride de série ou « plugin ».The illustrates a system coupled between the electric machines ST, SF allowing the system to operate as a standard hybrid vehicle or "plugin".

La illustre le coupleur SF bloqué permettant de faire fonctionner le système en véhicule hybride de série avec extension de jauge (REX).The illustrates the blocked SF coupler allowing the system to operate in a series hybrid vehicle with gauge extension (REX).

Concernant le pilotage, le système de couplage/découplage, en particulier le mécanisme de crabotage CR, peut être piloté par actionnement électromagnétique.Concerning the control, the coupling/decoupling system, in particular the dog clutch mechanism CR, can be controlled by electromagnetic actuation.

Plus particulièrement, l’actionnement du crabot CR pourra être électromagnétique direct au via un palonnier de commande. L’actionnement électromagnétique pourra être intégré sur les parties tournantes de préférence avec un collecteur électrique tournant (non représenté).More specifically, the actuation of the CR dog clutch may be direct electromagnetic or via a control bar. The electromagnetic actuation can be integrated on the rotating parts preferably with a rotating electrical collector (not shown).

Dans les autres cas, une liaison mécanique de type plateau tournant ou fourchette, peut être utilisée afin de transmettre le mouvement vers le crabot CR.In other cases, a mechanical connection of the turntable or fork type can be used in order to transmit the movement to the dog clutch CR.

Lors du décrabotage comme du recrabotage le coupleur magnétique ST peut être piloté afin d’annuler la vitesse entre les deux rotors ST, SF de manière à pouvoir dégager/engager le crabot CR.During disengagement as well as re-engagement, the magnetic coupler ST can be controlled in order to cancel the speed between the two rotors ST, SF so as to be able to disengage/engage the dog clutch CR.

On peut aussi envisager un système de couplage/découplage comprenant un moyen de glissement à embrayage suivant des modes de réalisation particuliers.It is also possible to envisage a coupling/decoupling system comprising a clutch sliding means according to particular embodiments.

L’invention est adaptée à un coupleur de type radial. Elle peut également être adaptée à des machines axiales ou une combinaison de machine radiale et machine axiale, pour y avoir les avantages susvisés.The invention is adapted to a radial-type coupler. It can also be adapted to axial machines or a combination of radial machine and axial machine, in order to have the aforementioned advantages.

L’invention concerne en outre une roue de véhicule R comprenant un système de transmission T tel que décrit précédemment.The invention further relates to a vehicle wheel R comprising a transmission system T as described above.

Un autre objet de l’invention concerne un véhicule automobile V comprenant un système de transmission T tel que décrit précédemment.Another object of the invention relates to a motor vehicle V comprising a transmission system T as described above.

L’invention concerne en outre une méthode de roulage d’un véhicule automobile comprenant un système de transmission T tel que décrit précédemment.The invention further relates to a method of driving a motor vehicle comprising a transmission system T as described above.

La méthode peut comprendre une étape pour coupler les machines électriques ST, SF lors de phases en dérivation de puissance.The method may include a step for coupling the electrical machines ST, SF during power bypass phases.

La méthode peut aussi comprendre une étape pour découpler les deux machines ST, SF lors des phases de roulage électrique.The method can also comprise a step for decoupling the two machines ST, SF during the electric driving phases.

La méthode peut aussi comprendre une étape pour coupler une machine ST au bâti fixe lors de phases à forte recharge.The method can also comprise a step for coupling an ST machine to the fixed frame during high recharging phases.

En particulier, selon le besoin une des étapes est mise en œuvre pour adapter le système à la situation et aux besoins.In particular, depending on the need, one of the steps is implemented to adapt the system to the situation and the needs.

Par exemple, le superviseur de la chaîne de traction détermine en fonction des paramètres énergétiques et de la vitesse du véhicule si les deux rotors ST, SF doivent être crabotés (phase de vie en dérivation de puissance) ou décrabotés (phase de vie en roulage électrique) ou si le rotor du coupleur ST doit être bloqué en rotation (phase de vie à forte recharge).For example, the powertrain supervisor determines, depending on the energy parameters and the speed of the vehicle, whether the two rotors ST, SF must be clutched (life phase in power bypass) or disengaged (life phase in electric driving ) or if the rotor of the ST coupler must be locked in rotation (high recharging life phase).

L’intérêt de l’invention est que dans les phases de vie où le superviseur demande un roulage électrique, alors le coupleur peur être décraboté afin de réduire les pertes et améliorer la consommation.The advantage of the invention is that in the phases of life where the supervisor requests electric driving, then the coupler can be disengaged in order to reduce losses and improve consumption.

De même pour les cas de vie où la puissance de recharge est élevée, le blocage en rotation du coupleur ST permet de recharger à forte puissance avec un rendement optimal.
Similarly for life cases where the recharging power is high, the rotational blocking of the ST coupler makes it possible to recharge at high power with optimal efficiency.
