Description

L'invention concerne un mécanisme de coupure de faisceau lumineux pour module optique et ledit module optique. Elle s'applique notamment à un module optique destiné à s'insérer dans un projecteur automobile, en particulier un projecteur elliptique, installé à l'avant du véhicule automobile.The invention relates to a light beam cut-off mechanism for an optical module and said optical module. It applies in particular to an optical module intended to be inserted into a motor vehicle headlight, in particular an elliptical headlight, installed at the front of the motor vehicle.

De tels modules optiques possèdent une source lumineuse qui projette de la lumière sur un réflecteur. La lumière est ensuite réfléchie sur une lentille afin d'être renversée et renvoyée sous forme d'un faisceau lumineux à l'extérieur du véhicule. Document EP 2169299 A1 divulgue un tel module optique.Such optical modules have a light source which projects light onto a reflector. The light is then reflected off a lens to be knocked down and reflected back as a beam of light outside the vehicle. Document EP 2169299 A1 discloses such an optical module.

L'invention s'intéresse plus particulièrement aux modules optiques comprenant une barrette de coupure rotative, actionnée électriquement pour se déplacer, sur commande, d'une première position angulaire, dans laquelle elle occulte une partie du faisceau lumineux afin de limiter la portée du projecteur à celle des feux de code pour ne pas éblouir les autres conducteurs circulant en sens inverse, à une deuxième position angulaire, dans laquelle elle n'occulte pas le faisceau lumineux, la portée du projecteur correspondant alors à celle des feux de route.The invention is more particularly interested in optical modules comprising a rotary cut-off strip, electrically actuated to move, on command, from a first angular position, in which it obscures a part of the light beam in order to limit the range of the projector. to that of the code lights so as not to dazzle other drivers traveling in the opposite direction, to a second angular position, in which it does not obscure the light beam, the range of the headlight then corresponding to that of the main beam.

La barrette de coupure est actionnée électriquement par un moteur afin de l'entrainer en rotation. Le moteur comprend pour cela un arbre de transmission entrainant en rotation un mécanisme d'engrenage de manière à transmettre à la barrette de coupure son mouvement de rotation.The cut-off bar is electrically actuated by a motor in order to drive it in rotation. For this, the motor comprises a transmission shaft driving a gear mechanism in rotation so as to transmit its rotational movement to the cut-off bar.

L'activation du moteur permet d'entrainer la barrette de coupure depuis sa première position correspondant aux feux de code jusqu'à une butée maintenant la barrette de coupure dans sa deuxième position correspondant aux feux de route. Le moteur est alors maintenu activé pour que l'arbre de transmission, par l'intermédiaire du mécanisme d'engrenage, maintienne la barrette de coupure dans cette position.Activation of the engine makes it possible to drive the cut-off bar from its first position corresponding to the code lights to a stop maintaining the cut-off bar in its second position corresponding to the high beams. The motor is then kept activated so that the transmission, through the gear mechanism, maintains the cut-off bar in this position.

Lorsque l'on souhaite repositionner la barrette de coupure dans sa première position, le moteur est désactivé. Son arbre de transmission est alors libre en rotation de sorte qu'il ne retient plus la barrette de coupure. Elle est alors entrainée par l'intermédiaire d'un ressort de rappel jusqu'à une butée définissant sa première position. Pendant cette rotation, c'est la barrette de coupure qui entraine l'arbre de transmission en rotation par l'intermédiaire du mécanisme d'engrenage.When you want to reposition the cut-off bar in its first position, the motor is deactivated. Its transmission shaft is then free to rotate so that it no longer retains the cut-off bar. It is then driven by means of a return spring to a stop defining its first position. During this rotation, it is the cut-off bar which drives the transmission shaft in rotation by means of the gear mechanism.

Or, il est nécessaire que la barrette de coupure passe rapidement de sa deuxième à sa première position afin de limiter le temps de transition entre les feux de route et les feux de codes. La force de rappel que le ressort exerce sur la barrette est donc importante et lorsque la barrette de coupure arrive contre la butée définissant sa première position, elle est ainsi soumise à des rebonds. Ces rebonds sont en outre amplifiés par l'inertie de l'arbre de transmission, entrainé avec la barrette comme vu précédemment, et du rotor du moteur auquel l'arbre de transmission est relié. Ces rebonds peuvent être perceptibles par le conducteur et ont pour conséquence une dégradation de la fonction code tant que la barrette de coupure n'est pas stabilisée.However, it is necessary for the cut-off bar to pass quickly from its second to its first position in order to limit the transition time between the main beam headlights and the running lights. The return force that the spring exerts on the bar is therefore significant and when the cut-off bar arrives against the stop defining its first position, it is thus subjected to rebounds. These rebounds are further amplified by the inertia of the transmission shaft, driven with the bar as seen above, and of the motor rotor to which the transmission shaft is connected. These bounces can be perceptible by the driver and result in a degradation of the code function as long as the cut-off bar is not stabilized.

L'invention vise à améliorer la situation. Elle concerne ainsi un mécanisme de coupure de module optique comprenant une barrette de coupure, un moteur entrainant la barrette de coupure entre au moins une première et une deuxième position par l'intermédiaire d'un arbre de transmission du moteur et d'un moyen d'entrainement de la barrette de coupure lié à l'arbre de transmission, un moyen de rappel tendant à ramener la barrette de coupure dans sa première position, caractérisé par le fait que le moyen d'entrainement comprend un dispositif de découplage du mouvement de l'arbre de transmission par rapport à celui de la barrette de coupure lorsque la barrette de coupure atteint la première position.The invention aims to improve the situation. It thus relates to an optical module cut-off mechanism comprising a cut-off bar, a motor driving the cut-off bar between at least a first and a second position via a transmission shaft of the motor and a means of 'drive of the cut-off bar linked to the transmission shaft, a return means tending to return the cut-off bar to its first position, characterized in that the drive means comprises a device for decoupling the movement of the 'transmission shaft relative to that of the cut-off bar when the cut-off bar reaches the first position.

Ainsi, grâce à l'invention et en particulier au dispositif de découplage, au moment où la barrette de coupure entre en contact avec une première butée définissant la première position de la barrette de coupure, son mouvement de rotation s'arrête alors que celui de l'arbre de transmission continue. Les rebonds de la barrette de coupure sont alors très fortement diminués puisqu'elle n'est pas soumise, à ce moment là, à l'inertie de l'arbre de transmission et que son inertie propre est très faible. L'arbre de transmission sera notamment ralenti du fait des caractéristiques internes du moteur, par exemple par frottement, et lorsque la barrette de coupure et l'arbre de transmission seront de nouveau couplés, la vitesse de rotation de l'arbre de transmission et donc son moment cinétique seront réduits.Thus, thanks to the invention and in particular to the decoupling device, at the moment when the cut-off bar comes into contact with a first stop defining the first position of the cut-off bar, its rotational movement stops while that of the continuous transmission shaft. The rebounds of the cut-off bar are then very greatly reduced since it is not subject, at this time, to the inertia of the transmission shaft and its own inertia is very low. The transmission shaft will in particular be slowed down due to the internal characteristics of the engine, for example by friction, and when the cut-off bar and the transmission shaft are again coupled, the speed of rotation of the transmission shaft and therefore its angular momentum will be reduced.

Selon un aspect de l'invention, ledit dispositif de découplage comporte un ou des moyens d'amortissement du mouvement de l'arbre de transmission une fois que la barrette de coupure a atteint la première position. Le mouvement de l'arbre de transmission est ainsi amorti davantage que par ses simple frottements ce qui a pour conséquence de réduire les rebonds subis par la barrette de coupure. L'amortissement se fait, par exemple, par le frottement d'une pièce sur une autre.According to one aspect of the invention, said decoupling device comprises one or more means for damping the movement of the transmission shaft once the cut-off bar has reached the first position. The movement of the transmission shaft is thus dampened more than by its simple friction, which has the consequence of reducing the rebounds undergone by the cut-off bar. Damping is done, for example, by the friction of one part on another.

Selon un exemple de réalisation de l'invention, le dispositif de découplage comprend une première pièce solidaire de l'arbre de transmission et une deuxième pièce entrainant la barrette de coupure en rotation, la première pièce étant entrainée par la deuxième pièce quand la barrette de coupure passe de la deuxième position à la première position, ladite première pièce se découplant de la deuxième pièce lorsque la barrette de coupure atteint la première position. Avantageusement, la deuxième pièce amortit le mouvement de la première pièce lorsque la barrette de coupure atteint la première position. Le moyen d'amortissement est de manière avantageuse constitué par le frottement entre la deuxième pièce et la première pièce.According to an exemplary embodiment of the invention, the decoupling device comprises a first part integral with the transmission shaft and a second part driving the cut-off bar in rotation, the first part being driven by the second part when the bar of cut passes from the second position to the first position, said first part decoupling from the second part when the cut strip reaches the first position. Advantageously, the second part dampens the movement of the first part when the cut-off bar reaches the first position. The damping means is advantageously constituted by the friction between the second part and the first part.

De manière avantageuse, la deuxième pièce comprend une denture réalisant un engrenage avec ladite barrette de coupure.Advantageously, the second part comprises a set of teeth forming a gear with said cut-off bar.

Selon un aspect de l'invention, la première et la deuxième pièces sont liées de manière à permettre un débattement angulaire de la première pièce par rapport à la deuxième pièce selon un axe de rotation de l'arbre de transmission. Le débattement angulaire autorise ainsi le découplage du mouvement de la première pièce par rapport à celui de la deuxième pièce lorsque la barrette de coupure atteint sa première position.According to one aspect of the invention, the first and second parts are linked so as to allow angular movement of the first part relative to the second part along an axis of rotation of the transmission shaft. The angular movement thus allows the movement of the first part to be decoupled from that of the second part when the cut-off bar reaches its first position.

Selon un exemple de réalisation de l'invention, la deuxième pièce comprend une rainure en forme de secteur angulaire et la première pièce comprend une nervure se déplaçant dans ladite rainure de manière à autoriser ledit débattement angulaire.According to an exemplary embodiment of the invention, the second part comprises a groove in the form of an angular sector and the first part comprises a rib moving in said groove so as to allow said angular movement.

Selon un aspect de l'invention, le moyen d'amortissement est constitué par le frottement entre la nervure et la rainure.According to one aspect of the invention, the damping means consists of the friction between the rib and the groove.

Avantageusement, la première pièce a la forme d'un cylindre situé au niveau d'une extrémité distale de l'arbre de transmission, ladite nervure étant située à la périphérie du cylindre.Advantageously, the first part has the shape of a cylinder located at a distal end of the transmission shaft, said rib being located at the periphery of the cylinder.

Selon un aspect de l'invention, la première pièce est située au centre de la deuxième pièce, ladite rainure en forme de secteur angulaire étant située à la périphérie de ladite première pièce. Ainsi le dispositif de découplage à la forme d'un cylindre d'engrenage classique comprenant la première pièce dans sa partie centrale et la deuxième pièce dans sa partie périphérique. Il peut de la sorte être intégré aux mécanismes de coupure existants sans besoin de modification du mécanisme de coupure.According to one aspect of the invention, the first part is located at the center of the second part, said groove in the form of an angular sector being located at the periphery of said first part. Thus the decoupling device in the form of a conventional gear cylinder comprising the first part in its central part and the second part in its peripheral part. It can thus be integrated into existing cut-off mechanisms without the need for modification of the cut-off mechanism.

L'invention concerne aussi un module optique comprenant un mécanisme de coupure tel que décrit précédemment.The invention also relates to an optical module comprising a cut-off mechanism as described above.

The light beam is then projected onto a lens 4 which reverses it and sends it back onto the road located in front of the vehicle in which the optical module is mounted. . The lens 4 is arranged on a lens holder 7. The light source here is a halogen lamp.

Le mécanisme de coupure 5 est disposé entre le réflecteur 3 et la lentille 4. Ce mécanisme de coupure 5 permet d'obturer plus ou moins le faisceau lumineux, en réaction à une commande de l'utilisateur du véhicule ou à une commande automatique, afin de proposer différents modes d'éclairages de la route.The cut-off mechanism 5 is arranged between the reflector 3 and the lens 4. This cut-off mechanism 5 makes it possible to more or less block the light beam, in reaction to a command from the user of the vehicle or to an automatic command, in order to to offer different ways of lighting the road.

Ce mécanisme de coupure 5 va maintenant être décrit plus en détail grâce aux figures 2 et 3. Dans la suite de la description, les qualifications avant, arrière, droite, gauche, supérieure et inférieure sont définies par rapport au sens de marche avant du véhicule, c'est-à-dire par rapport au sens de la flèche référencée 80 sur la figure 2.This cut-off mechanism 5 will now be described in more detail thanks to the figures 2 and 3 . In the remainder of the description, the front, rear, right, left, upper and lower ratings are defined with respect to the direction of forward travel of the vehicle, that is to say with respect to the direction of the arrow referenced 80 on the figure 2 .

Le mécanisme de coupure 5 comprend une barrette de coupure 10. Il s'agit ici d'un mécanisme de coupure bi-fonction, c'est-à-dire que la barrette de coupure peut se positionner selon deux positions, une première position dans laquelle elle obture partiellement le faisceau lumineux et correspondant au feu de code et une deuxième position dans laquelle elle n'obture pas ou moins le faisceau lumineux et correspondant au feu de route. Dans sa première position, la barrette de coupure 10 s'étend selon un plan sensiblement vertical alors que dans sa deuxième position elle s'étend dans un plan sensiblement horizontal.The cut-off mechanism 5 comprises a cut-off bar 10. This is a dual-function cut-off mechanism, that is to say that the cut-off bar can be positioned in two positions, a first position in which it partially blocks the light beam and corresponding to the code light and a second position in which it does not or less block the light beam and corresponding to the main beam. In its first position, the cut-off bar 10 extends in a substantially vertical plane, while in its second position it extends in a substantially horizontal plane.

La barrette de coupure 10 est positionnée en face de la source lumineuse. Elle est montée sur un support 11 de barrette comprenant une première partie 12 disposant d'un engrenage 14, située au niveau d'une première extrémité longitudinale 72 de la barrette 10. La première partie est ici en forme d'un secteur de disque et comprend une partie centrale 21 à la périphérie de laquelle se trouve l'engrenage 14. Le support 11 de la barrette comprend également une deuxième partie 13 disposant d'un moyen de rappel, notamment un ressort de rappel 15, tendant à ramener la barrette 10 dans la première position, c'est-à-dire dans sa position sensiblement verticale, la deuxième partie 13 étant située au niveau d'une deuxième extrémité longitudinale 73 de la barrette 10. La première extrémité longitudinale 72 est située à gauche de la barrette 10 sur la figure 2 alors que la deuxième extrémité longitudinale 73 est située à droite de la barrette 10.The cut-off bar 10 is positioned opposite the light source. It is mounted on a bar support 11 comprising a first part 12 having a gear 14, located at a first longitudinal end 72 of the bar 10. The first part is here in the form of a disc sector and comprises a central part 21 at the periphery of which the gear 14 is located. The support 11 of the bar also comprises a second part 13 having a return means, in particular a return spring 15, tending to bring back the bar 10 in the first position, that is to say in its substantially vertical position, the second part 13 being located at a second longitudinal end 73 of the bar 10. The first longitudinal end 72 is located to the left of bar 10 on the figure 2 while the second longitudinal end 73 is located to the right of the bar 10.

La barrette 10 est ici en acier. Elle est de forme sensiblement rectangulaire et agencée pour obturer plus ou moins le faisceau lumineux comme expliqué précédemment, c'est-à-dire pour couper plus ou moins le faisceau lumineux.The bar 10 is here made of steel. It is of substantially rectangular shape and designed to more or less block the light beam as explained above, that is to say to cut the light beam more or less.

Le support 11 de barrette est monté sur une armature 50 du mécanisme de coupure 5. Le mécanisme de coupure 5 comprend également un moyen d'entrainement 90 comprenant notamment la première partie 12 du support 11 et un pignon muni d'une denture, actionné par un moteur à courant continu 30. Le moyen d'entrainement 90 est relié à un arbre d'entrainement 38 du moteur à courant continu 30 de manière à entrainer la barrette de coupure.The bar support 11 is mounted on a frame 50 of the cut-off mechanism 5. The cut-off mechanism 5 also comprises a drive means 90 comprising in particular the first part 12 of the support 11 and a pinion provided with teeth, actuated by a DC motor 30. The drive means 90 is connected to a drive shaft 38 of the DC motor 30 so as to drive the cut-off bar.

Le moteur 30 est de forme sensiblement parallélépipédique de sorte qu'il comprend une face supérieure 32, une face avant 33, une face inférieure 34, une face arrière 35, une face gauche 36 et une face droite 37. La face supérieure 32 et la face inférieure 34, opposées entre elles sont de formes courbées.The motor 30 is of substantially parallelepipedal shape so that it comprises an upper face 32, a front face 33, a lower face 34, a rear face 35, a left face 36 and a right face 37. The upper face 32 and the lower face 34, opposite to each other, are of curved shapes.

Au niveau de la face gauche 36 du moteur 30 se situe le moyen d'entrainement 90. Il est relié à l'arbre de transmission 38, faisant saillie par rapport à la face gauche 36 du moteur 30 et situé sensiblement au milieu de la face gauche 36 du moteur 30.At the level of the left face 36 of the motor 30 is located the drive means 90. It is connected to the transmission shaft 38, projecting relative to the left face 36 of the motor 30 and situated substantially in the middle of the face. left 36 of engine 30.

Le moteur 30 est monté sur un support de moteur 40 situé au centre et vers l'avant de l'armature 50, c'est-à-dire entre le moteur et lentille, une fois le mécanisme de coupure 5 monté dans le module optique.The motor 30 is mounted on a motor support 40 located in the center and towards the front of the frame 50, that is to say between the motor and the lens, once the cut-off mechanism 5 is mounted in the optical module. .

Le mécanisme de coupure 5 comprend également un écran thermique 60 épousant une face externe du support 40 du moteur 30 dirigée vers l'avant. L'écran thermique 60 est ainsi situé entre le support 40 de moteur et la lentille. Il est en métal de sorte qu'il protège le support 40 de moteur et le moteur 30 des rayons du soleil.The cut-off mechanism 5 also comprises a heat shield 60 conforming to an outer face of the support 40 of the motor 30 facing forward. The heat shield 60 is thus located between the motor support 40 and the lens. It is made of metal so that it protects the motor mount 40 and the motor 30 from sunlight.

La partie centrale 21 de la première partie 12 du support 11 comprend une lumière (non visible) coopérant avec un bossage 61 du mécanisme de coupure 5 situé sur l'armature 50. La liberté de déplacement du bossage 61 dans la lumière définit la rotation que doit effectuer la barrette de coupure entre sa première position et sa deuxième position. Ainsi la lumière définit une première butée contre laquelle le bossage 61 vient en butée lorsque la barrette de coupure est dans sa première position et une deuxième butée contre laquelle le bossage 61 vient en butée lorsque la barrette de coupure est dans sa deuxième position.The central part 21 of the first part 12 of the support 11 comprises a light (not visible) cooperating with a boss 61 of the cut-off mechanism 5 located on the frame 50. The freedom of movement of the boss 61 in the light defines the rotation that must make the cut-off bar between its first position and its second position. Thus the light defines a first stop against which the boss 61 abuts when the cut-off bar is in its first position and a second stop against which the boss 61 abuts when the cut-off bar is in its second position.

Le moteur 30 entraine la barrette de coupure par l'intermédiaire de son moyen d'entrainement 90 et de l'arbre de transmission 38 de sa première position jusqu'à sa deuxième position en basculant ici la barrette de coupure vers l'avant. Tant que l'on souhaite maintenir la barrette de coupure 10 en position de feux de route, c'est-à-dire dans sa deuxième position, le moteur reste activé pour que son arbre de transmission 38 maintienne la barrette de coupure 10 dans cette position par l'intermédiaire du moyen d'entrainement 90.The motor 30 drives the cut-off bar via its drive means 90 and the transmission shaft 38 from its first position to its second position, here tilting the cut-off bar forward. As long as it is desired to keep the cut-off bar 10 in the main beam position, that is to say in its second position, the engine remains activated so that its transmission shaft 38 maintains the cut-off bar 10 in this position. position via the drive means 90.

Lorsque le moteur est désactivé, son arbre de transmission 38 devient libre en rotation et la barrette de coupure 10 est amenée à sa première position grâce au ressort de rappel 15.When the engine is deactivated, its transmission shaft 38 becomes free to rotate and the cut-off bar 10 is brought to its first position thanks to the return spring 15.

Selon l'invention, le moyen d'entrainement 90 comprend un dispositif de découplage 81 du mouvement de l'arbre de transmission 38 par rapport à celui de la barrette de coupure 10 lorsque la barrette de coupure 10 atteint la première position.According to the invention, the drive means 90 comprises a device 81 for decoupling the movement of the transmission shaft 38 relative to that of the cut-off bar 10 when the cut-off bar 10 reaches the first position.

Ainsi, au moment où la première butée du moyen d'entrainement 90 arrive contre le bossage 61, la barrette de coupure est arrêtée dans sa première position et l'arbre de transmission 38 continue à tourner grâce au dispositif de découplage ne provoquant donc pas de rebonds de la barrette de coupure 10.Thus, when the first stop of the drive means 90 arrives against the boss 61, the cut-off bar is stopped in its first position and the transmission shaft 38 continues to rotate thanks to the decoupling device thus not causing any interference. rebounds of the cut-off bar 10.

Le dispositif de découplage 81 est décrit de manière plus détaillée sur les figures 4 à 6. On remarque sur ces figures qu'il comprend une première pièce 82 sensiblement cylindrique, coaxiale et liée à l'arbre de transmission 38, c'est-à-dire que la première pièce est solidaire de l'arbre de transmission 38. La première pièce 82 comprend, un anneau 91, situé au niveau de sa base, c'est-à-dire de sa partie située la plus proche du moteur. L'anneau 91 est de diamètre supérieur à la forme cylindrique de la première pièce 82. La première pièce 82 peut être située au niveau d'une extrémité distale de l'arbre de transmission 38. Elle comprend une nervure 87 qui s'étend radialement à la périphérie du cylindre.The decoupling device 81 is described in more detail on the figures 4 to 6 . Note in these figures that it comprises a first part 82 which is substantially cylindrical, coaxial and linked to the transmission shaft 38, that is to say that the first part is integral with the transmission shaft 38. The first part part 82 comprises a ring 91, located at its base, that is to say of its part located closest to the engine. The ring 91 is of greater diameter than the cylindrical shape of the first part 82. The first part 82 may be located at a distal end of the transmission shaft 38. It comprises a rib 87 which extends radially. at the periphery of the cylinder.

Le dispositif de découplage comprend également une deuxième pièce 83 sensiblement cylindrique et entrainant la barrette de coupure. Dans l'exemple illustré, la deuxième pièce 83 entraine la barrette de coupure par l'intermédiaire de la première partie 12 du support de barrette comprenant l'engrenage.The decoupling device also comprises a second part 83 which is substantially cylindrical and driving the cut-off bar. In the example illustrated, the second part 83 drives the cut-off bar by means of the first part 12 of the bar support comprising the gear.

La deuxième pièce 83 est ici un pignon comprenant une denture 89. La deuxième pièce 83 peut ainsi s'engrener avec le l'engrenage de la première partie afin d'entrainer la barrette de coupure. La deuxième pièce comprend une ouverture centrale, coaxiale à l'arbre de transmission. La deuxième pièce 83 comprend une rainure 84 s'enfonçant radialement, depuis l'ouverture centrale vers l'extérieur, dans l'épaisseur du pignon. La rainure 84 est ici en forme de secteur angulaire. Elle s'étend entre une première extrémité 85 située sur la gauche de la figure 4 et une deuxième extrémité 86 située sur la droite de la figure 4. La première pièce est située ici au centre de la deuxième pièce 83. La rainure 84 est située autour de la première pièce 82, notamment à la périphérie de celle-ci.The second part 83 is here a pinion comprising a toothing 89. The second part 83 can thus mesh with the gear of the first part in order to drive the cut-off bar. The second part comprises a central opening, coaxial with the transmission shaft. The second part 83 comprises a groove 84 which is inserted radially, from the central opening outwards, into the thickness of the pinion. The groove 84 is here in the form of an angular sector. It extends between a first end 85 located on the left of the figure 4 and a second end 86 located on the right of the figure 4 . The first room is located here in the center of the second room 83. The groove 84 is located around the first part 82, in particular at the periphery of the latter.

L'ouverture centrale de la deuxième pièce 83 accueille la première pièce 82 et c'est la rainure 84 qui accueille la nervure 87. La première pièce 82 est ainsi insérée dans la deuxième pièce 83 de sorte que l'anneau 91 soit au contact de la deuxième pièce 83. Ainsi le dispositif de découplage 81 a la forme d'un pignon classique et peut être positionné sur un arbre de transmission de l'art antérieur sans nécessiter d'adaptation particulière de l'arbre de transmission 38.The central opening of the second part 83 receives the first part 82 and it is the groove 84 which accommodates the rib 87. The first part 82 is thus inserted into the second part 83 so that the ring 91 is in contact with the second part 83. Thus the decoupling device 81 has the shape of a conventional pinion and can be positioned on a transmission shaft of the prior art without requiring particular adaptation of the transmission shaft 38.

La rainure 84 est située à la périphérie de la première pièce 82. Elle autorise la première pièce 82 à tourner autour de l'axe de l'arbre de transmission, à l'intérieur du secteur angulaire qu'elle définit sans que la deuxième pièce 83 ne tourne. On comprend ici que la première pièce 82 et la deuxième pièce 83 sont liées de manière à permettre un débattement angulaire de la première pièce 82 par rapport à la deuxième pièce 83 selon un axe de rotation de l'arbre de transmission 38.The groove 84 is located at the periphery of the first part 82. It allows the first part 82 to rotate around the axis of the transmission shaft, inside the angular sector that it defines without the second part 83 does not turn. It is understood here that the first part 82 and the second part 83 are linked so as to allow angular displacement of the first part 82 relative to the second part 83 along an axis of rotation of the transmission shaft 38.

Le mouvement de la première pièce 82 dans la rainure 84 est ainsi découplé du mouvement de la deuxième pièce 83. En effet, lorsque le moteur 30 entraine la barrette de coupure 10 de la première à la deuxième position, son arbre de transmission 38 tourne ici selon le sens des aiguilles d'une montre sur la figure 4 de sorte que la nervure 87 appuie sur la deuxième extrémité 86 de la rainure 84 et entraine ainsi en rotation la deuxième pièce 83 qui entraine à son tour la barrette de coupure par l'intermédiaire de l'engrenage. Lorsque le moteur 30 est désactivé, le ressort de rappel 15 appuie, par l'intermédiaire de la première partie 13, contre la barrette de coupure 10 qui entraine alors l'engrenage 14 qui entraine à son tour la deuxième pièce 83 dans une rotation dans le sens inverse des aiguilles d'une montre sur la figure 4. Cette dernière entraine alors la première pièce 82 dont la nervure 87 se trouve en butée contre la deuxième extrémité 86 de la rainure 84. Ainsi, lorsque la première butée arrive contre le bossage c'est-à-dire au moment où la barrette de coupure arrive dans sa première position, elle s'arrête de tourner, ce qui a pour conséquence d'arrêter la rotation de l'engrenage et donc de la deuxième pièce 83. L'arbre de transmission 38 continue cependant sa rotation du fait de son inertie, la rainure 84 autorisant alors le déplacement de la nervure 87 et donc de la première pièce 82 liée à l'arbre de transmission 38. On obtient ainsi, sur l'étendue de la rainure, un découplage du mouvement de l'arbre de transmission 38 par rapport à celui de la barrette de coupure lorsque cette dernière atteint sa première position.The movement of the first part 82 in the groove 84 is thus decoupled from the movement of the second part 83. Indeed, when the motor 30 drives the cut-off bar 10 from the first to the second position, its transmission shaft 38 turns here. clockwise on the figure 4 so that the rib 87 presses on the second end 86 of the groove 84 and thus drives the second part 83 in rotation which in turn drives the cut-off bar via the gear. When the motor 30 is deactivated, the return spring 15 presses, via the first part 13, against the cut-off bar 10 which then drives the gear 14 which in turn drives the second part 83 in a rotation in counterclockwise on the figure 4 . The latter then drives the first part 82, the rib 87 of which is in abutment against the second end 86 of the groove 84. Thus, when the first stop arrives against the boss i.e. when the cut-off bar arrives in its first position, it stops rotating, which has the consequence of stopping the rotation of the gear and therefore of the second part 83. The transmission shaft 38 however continues its rotation due to its inertia, the groove 84 then allowing the displacement of the rib 87 and therefore of the first part 82 linked to the transmission shaft 38. The result is thus, over the extent of the groove, a decoupling of the movement of the transmission shaft 38 relative to that of the cut-off bar when the latter reaches its first position.

La nervure 87 parcourt le trajet défini par la rainure 84 jusqu'à arriver en butée contre la première extrémité 85 de la rainure 84. L'arbre de transmission étant soumis à des frottements internes au moteur, il perd ainsi de la vitesse pendant sa rotation correspondant au secteur angulaire défini par la rainure. Sa quantité de mouvement sera ainsi réduite de sorte que les rebonds auxquels est soumise la barrette de coupure seront réduits.The rib 87 travels the path defined by the groove 84 until it comes into abutment against the first end 85 of the groove 84. The transmission shaft being subjected to internal friction in the engine, it thus loses speed during its rotation. corresponding to the angular sector defined by the groove. Its momentum will thus be reduced so that the rebounds to which the cut-off bar is subjected will be reduced.

Le dispositif de découplage 81 peut également comprendre un ou des moyens d'amortissement de sorte que le mouvement de l'arbre de transmission soit davantage freiné et que sa vitesse soit davantage réduite lorsque la nervure 87 arrive à la première extrémité 85 de la rainure 84. Ces moyens d'amortissement comprennent ici la première pièce 82 et la deuxième pièce 83 et sont constitués en particulier des frottements entre la première pièce 82 et la deuxième pièce 83, notamment entre la nervure 87 et le fond de la rainure 84. Des frottements entre la première pièce 82 et la deuxième pièce 83 autres que ceux réalisés entre la nervure 87 et la rainure 84 peuvent également amortir le mouvement de l'arbre de transmission 38.The decoupling device 81 may also include one or more damping means so that the movement of the transmission shaft is further braked and its speed is further reduced when the rib 87 arrives at the first end 85 of the groove 84. These damping means here comprise the first part 82 and the second part 83 and in particular consist of friction between the first part 82 and the second part 83, in particular between the rib 87 and the bottom of the groove 84. Frictions between the first part 82 and the second part 83 other than those made between the rib 87 and the groove 84 can also dampen the movement of the transmission shaft 38.

Il est possible de choisir un débattement angulaire entre la première pièce et la deuxième pièce en changeant les dimensions de la rainure 84 en fonction notamment de l'amortissement désiré du mouvement de l'arbre de transmission 38.It is possible to choose an angular displacement between the first part and the second part by changing the dimensions of the groove 84 as a function in particular of the desired damping of the movement of the transmission shaft 38.
