La présente invention concerne un dispositif d'accouplement élastique entre le rotor d'une machine électrique tournante réversible et l'arbre vilebrequin d'un moteur thermique notamment d'un groupe motopropulseur hybride d'un véhicule automobile. The present invention relates to an elastic coupling device between the rotor of a reversible rotary electrical machine and the crankshaft of a heat engine, in particular of a hybrid powertrain of a motor vehicle.
Le rotor de la machine électrique tournante, qui peut être un alternateur-démarreur, est solidaire d'un moyeu monté coaxialement à l'arbre vilebrequin entraînant en rotation un volant d'inertie par l'intermédiaire d'un couvercle d'embrayage solidaire en rotation de ce volant. The rotor of the rotary electric machine, which can be an alternator-starter, is integral with a hub mounted coaxially with the crankshaft driving in rotation a flywheel by means of a clutch cover integral in rotation of this steering wheel.
Des moyens d'accouplement sont prévus entre le moyeu du rotor de la machine électrique et le couvercle d'embrayage. Coupling means are provided between the hub of the rotor of the electric machine and the clutch cover.
Cependant, ces moyens d'accouplement ont pour inconvénient d'être sensibles aux déplacements du vilebrequin ainsi qu'au fonctionnement acyclique du moteur thermique et aux déformations géométriques de cet arbre, provoquant de la sorte des dysfonctionnements de la machine électrique. En outre, les moyens d'accouplement ne sont pas adaptés pour compenser un désalignement pouvant intervenir entre le rotor de la machine électrique et l'arbre vilebrequin du moteur thermique. Enfin, les moyens d'accouplement sont d'une structure relativement complexe et rendent extrêmement difficiles le montage ou le démontage du couvercle d'embrayage relativement au moyeu du rotor de la machine électrique. However, these coupling means have the disadvantage of being sensitive to the movements of the crankshaft as well as to the acyclic operation of the heat engine and to the geometric deformations of this shaft, thereby causing malfunctions of the electric machine. In addition, the coupling means are not suitable for compensating for a misalignment which may occur between the rotor of the electric machine and the crankshaft of the heat engine. Finally, the coupling means are of a relatively complex structure and make it extremely difficult to assemble or disassemble the clutch cover relative to the hub of the rotor of the electric machine.
La présente invention a pour but d'éliminer les inconvénients ci-dessus en proposant un dispositif d'accouplement élastique entre le rotor d'une machine électrique tournante réversible et l'arbre vilebrequin d'un moteur thermique d'un groupe motopropulseur hybride d'un véhicule automobile, le rotor étant solidaire d'un moyeu monté coaxialement à l'arbre vilebrequin entraînant en rotation un volant d'inertie auquel est solidarisé en rotation un couvercle d'embrayage, et qui est caractérisé en ce qu'il comprend un boîtier d'accouplement de forme The present invention aims to eliminate the above drawbacks by proposing an elastic coupling device between the rotor of a reversible rotary electric machine and the crankshaft of a heat engine of a hybrid powertrain of a motor vehicle, the rotor being integral with a hub mounted coaxially with the crankshaft driving in rotation a flywheel to which is attached in rotation a clutch cover, and which is characterized in that it comprises a housing form coupling

Chaque bloc en élastomère est bilatéralement maintenu précontraint en direction circonférentielle entre deux pattes rigides solidaires du plateau de la seconde partie du boîtier perpendiculairement à celui-ci. Each elastomer block is bilaterally held prestressed in the circumferential direction between two rigid tabs integral with the plate of the second part of the housing perpendicularly thereto.
La face radialement interne de chaque bloc en élastomère est formée sur sa majeure partie par une pièce en tôle emboutie solidaire du bloc et comportant les deux rampes de sens opposés et la rainure centrale. The radially internal face of each elastomer block is formed over its major part by a stamped sheet metal part integral with the block and comprising the two ramps in opposite directions and the central groove.
Chaque tenon est situé au sommet d'une pièce en tôle en forme générale de dôme fixée sur une paroi rigide en forme de secteur solidaire du plateau de la première partie de boîtier perpendiculairement à celui-ci, de façon à permettre un déplacement radial élastique du tenon lors de l'accouplement de la première partie de boîtier à la seconde partie de boîtier. Each tenon is located at the top of a sheet metal part in the general shape of a dome fixed on a rigid wall in the form of a sector integral with the plate of the first housing part perpendicular to the latter, so as to allow an elastic radial displacement of the lug when coupling the first housing part to the second housing part.
Chaque bloc en élastomère est fixé sur une patte de support rigide solidaire du plateau de la seconde partie de boîtier perpendiculairement à celui-ci. Each elastomer block is fixed to a rigid support lug integral with the plate of the second housing part perpendicular to the latter.
Le plateau de la seconde partie de boîtier est fixé sur la partie centrale cylindrique du moyeu par un circlips fixé sur cette partie et au moins une rondelle élastique montée concentriquement sur la partie centrale cylindrique et interposée entre le circlips et le plateau pour plaquer ce dernier au fond du moyeu du rotor.

L'accouplement de la première partie de boîtier 35 à la seconde partie de boîtier 36 ressort déjà de la description qui précède et va être maintenant expliqué. The coupling of the first housing part 35 to the second housing part 36 is already apparent from the above description and will now be explained.
Après avoir fixé la seconde partie de boîtier 36 et ses blocs en élastomère 37 dans le moyeu 11 et la première partie de boîtier 35 et ses tenons 49 au couvercle d'embrayage 22 lui-même fixé au carter 4 du moteur thermique, ce dernier est positionné relativement au rotor 6 de la machine électrique 1 pour amener la première partie de boîtier 35 en regard du moyeu 11. Ensuite, le moteur est déplacé de façon à introduire en aveugle la première partie de boîtier 35 dans le moyeu 11 en amenant les tenons 49 en appui respectivement sur les faces en rampe correspondantes des blocs en élastomère 37. Par alimentation de la machine électrique 1, le rotor 6 et le moyeu 11 ainsi que la seconde partie de boîtier 36 et ses blocs en élastomère 37 sont tournés dans le sens approprié et d'une valeur d'angle déterminée de façon à déplacer les tenons 49 le long des faces en rampe correspondantes 43 avec déplacement en direction radiale interne de ces tenons à l'encontre de la force élastique de rappel des parois latérales 50 et à engager élastiquement les tenons 49 respectivement dans les gorges 42, chacune de section transversale en forme de V. After having fixed the second housing part 36 and its elastomer blocks 37 in the hub 11 and the first housing part 35 and its pins 49 to the clutch cover 22 itself fixed to the casing 4 of the heat engine, the latter is positioned relative to the rotor 6 of the electric machine 1 to bring the first housing part 35 facing the hub 11. Then, the motor is moved so as to blindly insert the first housing part 35 in the hub 11 by bringing the pins 49 bearing respectively on the corresponding ramp faces of the elastomer blocks 37. By powering the electric machine 1, the rotor 6 and the hub 11 as well as the second housing part 36 and its elastomer blocks 37 are turned in the direction suitable and with a value of angle determined so as to move the studs 49 along the corresponding ramp faces 43 with displacement in the internal radial direction of these studs against of the elastic return force of the side walls 50 and of elastically engaging the pins 49 respectively in the grooves 42, each of V-shaped cross section.
Lors d'un fonctionnement acyclique du moteur thermique ou de déformations géométriques du vilebrequin de ce moteur, les écarts en torsion résultant appliqués entre les deux parties 35, 36 du boîtier d'accouplement 34 sont amortis par les blocs en élastomère 37 sur lesquels agissent les tenons 49 suivant le sens du mouvement de torsion. Les blocs en élastomère 37 sont montés au plateau 38 de la seconde partie de boîtier 36 de façon à procurer la même raideur en direction circonférentielle. During acyclic operation of the heat engine or of geometric deformations of the crankshaft of this engine, the resulting torsional deviations applied between the two parts 35, 36 of the coupling housing 34 are absorbed by the elastomer blocks 37 on which the let us hold 49 in the direction of the torsional movement. The elastomer blocks 37 are mounted on the plate 38 of the second housing part 36 so as to provide the same stiffness in the circumferential direction.
Le boîtier 36 a ainsi une double fonction d'une part d'amortissement ou de limiteur de couple permettant la filtration des déplacements du vilebrequin et du The housing 36 thus has a double function on the one hand of damping or of torque limiter allowing the filtration of the movements of the crankshaft and of the
