Description

L'invention concerne un verrou débrayable pour un mécanisme de serrure automobile.The invention relates to a disengageable lock for an automobile lock mechanism.

L'adjonction d'un mécanisme de débrayage sur un verrou destiné à une serrure automobile permet d'éviter que ce verrou ne soit forcé. En effet, si une fausse clé, ou tout autre outil plat de forme adéquate, est introduite dans le rotor, et si on tente alors d'entraîner en rotation le rotor, le mécanisme de débrayage permet au rotor et à une douille intermédiaire de pivoter librement à l'intérieur du stator sans que ne s'exercent sur les paillettes des efforts importants.The addition of a disengagement mechanism on a lock for an automobile lock makes it possible to prevent this lock from being forced. Indeed, if a false key, or any other flat tool of adequate form, is introduced into the rotor, and if it then attempts to rotate the rotor, the disengaging mechanism allows the rotor and an intermediate sleeve to rotate freely inside the stator without significant effort being exerted on the glitter.

En effet, en présence d'efforts trop importants, les paillettes sont susceptibles d'être détériorées ou d'être escamotées, en force, ce qui permet alors de déverrouiller le verrou sans la clé conforme.Indeed, in the presence of excessive effort, flakes are likely to be deteriorated or to be retracted, in force, which then allows to unlock the lock without the key compliant.

L'invention se rapporte plus précisément à un verrou débrayable, notamment pour un mécanisme de serrure de véhicule automobile, comportant un stator fixe, une douille intermédiaire tubulaire qui est montée en rotation autour de son axe dans le stator et qui est fixe axialement par rapport au stator, un rotor qui est monté en rotation dans la douille, qui est fixe axialement dans la douille et qui comporte des paillettes mobiles radialement sous l'action d'une clé destinée à être introduite axialement dans le rotor. Des paillettes sont entièrement escamotées à l'intérieur du rotor lorsque la clé est conforme, de manière à permettre une libre rotation du rotor par rapport à la douille et au stator et ainsi permettre l'entraînement en rotation d'un levier de commande, appelé batteuse, de la serrure qui est accouplé au rotor par l'intermédiaire d'un entraîneur. Le rotor et la douille intermédiaire sont bloqués en rotation l'un par rapport à l'autre par les paillettes lorsque la clé n'est pas conforme. Le verrou comporte également un indexeur qui est mobile axialement entre une position de repos et une position de débrayage, sous l'effet d'une rotation de la douille par rapport au stator consécutive à l'entraînement en rotation du rotor à l'aide d'une clé non conforme, pour déplacer axialement l'entraîneur vers une position débrayée.The invention relates more specifically to a disengageable bolt, in particular for a motor vehicle lock mechanism, comprising a fixed stator, a tubular intermediate bush which is rotatably mounted about its axis in the stator and which is axially fixed relative to the stator, a rotor which is rotatably mounted in the sleeve, which is fixed axially in the sleeve and which comprises flakes movable radially under the action of a key intended to be introduced axially into the rotor. Flakes are completely retracted inside the rotor when the key is compliant, so as to allow free rotation of the rotor relative to the sleeve and the stator and thus allow the rotational drive of a control lever, called thresher, the lock that is coupled to the rotor via a coach. The rotor and the intermediate sleeve are locked in rotation relative to one another by the flakes when the key is not in conformity. The lock also comprises an indexer which is movable axially between a rest position and a disengagement position, under the effect of a rotation of the bushing relative to the stator consecutive to the rotational drive of the rotor with the aid of a wrong key, to axially move the coach to a disengaged position.

Un tel verrou débrayable est décrit dans le document de brevet FR 2 748 513 .Such a disengageable lock is described in the patent document FR 2,748,513 .

Selon ce verrou connu, l'indexeur et l'entraîneur sont dans une configuration sensiblement de disposition bout à bout. Ces deux pièces sont sensiblement disposées l'une en prolongement de l'autre.According to this known lock, the indexer and the trainer are in a substantially end-to-end configuration. These two parts are substantially arranged one in extension of the other.

L'indexeur est solidaire en rotation de la douille intermédiaire et est guidé en translation dans cette dernière. L'entraîneur est quant à lui guidé en rotation sur le rotor.The indexer is integral in rotation with the intermediate sleeve and is guided in translation in the latter. The coach is guided in rotation on the rotor.

L'indexeur comporte un anneau principal et des pattes de guidage qui s'étendent axialement depuis l'anneau et qui sont destinées à être reçues dans des encoches axiales correspondantes de la douille intermédiaire. Il comporte également deux ergots qui s'étendent axialement dans le sens inverse dans le prolongement de deux pattes de guidage diamétralement opposées.The indexer comprises a main ring and guide tabs which extend axially from the ring and which are intended to be received in corresponding axial slots of the intermediate sleeve. It also comprises two lugs which extend axially in the opposite direction in the extension of two diametrically opposite guide lugs.

Cet agencement de verrou pose les problèmes techniques suivants.This lock arrangement poses the following technical problems.

De par sa configuration en disposition bout à bout, la longueur d'un tel verrou est relativement importante.By its configuration in end-to-end arrangement, the length of such a lock is relatively important.

Par ailleurs, l'indexeur est une pièce relativement fragile de par sa constitution.Moreover, the indexer is a relatively fragile piece by its constitution.

L'invention résout ces problèmes en proposant un verrou débrayable particulièrement compact, c'est-à-dire de longueur limitée, et de constitution particulièrement robuste. On connaît le document DE 196 26 914 C1 , qui décrit un verrou débrayable pour mécanisme de serrure de véhicule automobile. Ce type de verrou débrayable, ne permet d'assurer, dans sa position débrayée, le blocage de la batteuse. Aussi, le problème technique à résoudre par l'objet de la présente invention, est de proposer un verrou débrayable pour mécanisme de serrure de véhicule automobile, selon le préambule de la revendication 1 qui permettrait d'éviter les problèmes de l'état de la technique et permettrait notamment d'assurer, dans sa position débrayée, le blocage de la batteuse.The invention solves these problems by providing a disengageable lock particularly compact, that is to say of limited length, and particularly robust constitution. We know the document DE 196 26 914 C1 which describes a disengageable latch for a motor vehicle lock mechanism. This type of disengageable latch does not ensure, in its disengaged position, blocking the thresher. Also, the technical problem to be solved by the object of the present invention is to propose a disengageable latch for a motor vehicle lock mechanism, according to the preamble of claim 1 which would make it possible to avoid the problems of the state of the invention. technique and in particular to ensure, in its disengaged position, blocking the thresher.

Avantageusement, le verrou comporte un ressort de compression intercalé entre la batteuse et l'entraîneur.Advantageously, the lock comprises a compression spring interposed between the thresher and the driver.

De préférence, l'entraîneur comporte sur son bord tourné vers la batteuse au moins une bride de guidage destinée à coopérer avec une encoche correspondante portée par la batteuse, cette encoche permettant une translation vers la batteuse de l'entraîneur à l'encontre de l'effort du ressort de compression.Preferably, the coach comprises on its edge turned towards the thresher at least one guide flange intended to cooperate with a corresponding notch carried by the threshing machine, this notch allowing a translation towards the threshing machine of the coach against the effort of the compression spring.

Ladite encoche peut être ouverte sur la face frontale arrière de la batteuse.Said notch may be open on the rear end face of the threshing machine.

On a représenté sur la figure 1 un verrou rotatif d'axe longitudinal A1 comportant des moyens de débrayage conforme aux enseignements de l'invention. Ce verrou est représenté sur les figure 2 à 7 en position initiale avnt introduction d'une clé.We have shown on the figure 1 a rotary latch of longitudinal axis A1 comprising disengaging means according to the teachings of the invention. This lock is represented on the figure 2 to 7 in initial position before introduction of a key.

Le verrou 10 comporte essentiellement un rotor 12 qui est monté tournant, autour de l'axe A1, à l'intérieur d'un stator 14 fixe, avec interposition entre les deux d'une douille intermédiaire 16 tubulaire qui est montée en rotation autour de son axe dans le stator et qui est fixe axialement par rapport au stator.The latch 10 essentially comprises a rotor 12 which is rotatably mounted about the axis A1, inside a fixed stator 14, with the interposition therebetween of an intermediate tubular bushing 16 which is rotatably mounted around its axis in the stator and which is axially fixed relative to the stator.

Une bille 60 est montée entre cuir et chair dans un orifice 16A traversant radial agencé sur la douille intermédiaire 16. Le rotor 12 d'une part comporte une cavité externe de réception 12B externe de cette bille et le stator 14 d'autre part comporte une cavité interne de réception 14B de cette bille. Cet orifice 16A, cette cavité du rotor 12B et cette cavité du stator 14B sont disposés de telle sorte qu'en position de repos, avant rotation d'une clé, l'orifice 16A, la cavité du rotor 12B et la cavité du stator 14B sont alignés comme représenté sur la figure 2.A ball 60 is mounted between leather and flesh in a radial through orifice 16A arranged on the intermediate sleeve 16. The rotor 12 on the one hand has an external external receiving cavity 12B of this ball and the stator 14 on the other hand comprises a internal receiving cavity 14B of this ball. This orifice 16A, this cavity of the rotor 12B and this cavity of the stator 14B are arranged such that in the position of rest, before rotation of a key, the orifice 16A, the cavity of the rotor 12B and the cavity of the stator 14B are aligned as shown on the figure 2 .

Le rotor 12 est destiné à être entraîné en rotation à l'aide d'une clé (non représentée) introduite axialement à l'intérieur du rotor 12 au travers d'une entrée de clé 18 agencée dans une face transversale avant 20 du rotor 12, laquelle face 20 est destinée par exemple à affleurer à l'extérieur d'un panneau de carrosserie (non représenté) du véhicule.The rotor 12 is intended to be rotated by means of a key (not shown) introduced axially inside the rotor 12 through a key inlet 18 arranged in a front transverse face 20 of the rotor 12 , which face 20 is intended for example to be flush with the outside of a body panel (not shown) of the vehicle.

L'extrémité axiale arrière 22 du rotor 12 est destinée à entraîner en rotation un levier de commande 24 d'un mécanisme de serrure (non représenté) pour autoriser la condamnation et la décondamnation d'un ouvrant du véhicule.The rear axial end 22 of the rotor 12 is intended to rotate a control lever 24 of a lock mechanism (not shown) to allow the locking and unlocking of an opening of the vehicle.

Le rotor 12 est susceptible d'entraîner en rotation le levier de commande 24, uniquement en présence d'une clé conforme, par l'intermédiaire d'un entraîneur 26 qui est mobile axialement dans le verrou 10, sous l'action d'un indexeur 28, entre une position embrayée dans laquelle il lie en rotation le rotor 12 et le levier de commande 24, et une position débrayée dans laquelle le rotor 12 n'est plus susceptible d'entraîner le levier 24 en rotation et dans laquelle l'entraîneur 26 assure le blocage en rotation du levier 24 par rapport au stator 14 du verrou 10.The rotor 12 is able to rotate the control lever 24, only in the presence of a suitable key, via a driver 26 which is axially movable in the latch 10, under the action of a indexer 28, between an engaged position in which it links in rotation the rotor 12 and the control lever 24, and a disengaged position in which the rotor 12 is no longer capable of driving the lever 24 in rotation and in which the The driver 26 locks the lever 24 in rotation relative to the stator 14 of the lock 10.

Le rotor 12, le stator 14 et la douille intermédiaire 16 sont immobiles en translation selon l'axe A1 l'un par rapport à l'autre et un ressort hélicoïdal de compression 30 est interposé entre la batteuse 24 et l'entraîneur 26 pour solliciter ce dernier axialement vers l'arrière vers sa position embrayée.The rotor 12, the stator 14 and the intermediate sleeve 16 are immobile in translation along the axis A1 relative to each other and a compression coil spring 30 is interposed between the thresher 24 and the driver 26 to solicit the latter axially towards the rear towards its engaged position.

Le stator 14 est de forme générale tubulaire cylindrique et il comporte des moyens (non représentés) qui permettent le montage et la fixation du verrou 10 sur le véhicule.The stator 14 is generally tubular cylindrical in shape and comprises means (not shown) which allow the mounting and fixing of the lock 10 on the vehicle.

De manière connue, le rotor 12 est destiné à recevoir des paillettes 32 agencées dans des plans transversaux qui se succèdent à intervalles réguliers selon la direction de l'axe A1 du verrou 10 et qui sont reçues dans des logements correspondants du rotor 12.In known manner, the rotor 12 is intended to receive flakes 32 arranged in successive transverse planes at regular intervals in the direction of the axis A1 of the latch 10 and which are received in corresponding housings of the rotor 12.

Les paillettes 32 sont mobiles radialement dans le rotor 12 et elles sont sollicitées élastiquement vers une position saillante dans laquelle elles dépassent partiellement à l'extérieur des logements du rotor 12.The flakes 32 are radially movable in the rotor 12 and they are elastically biased towards a protruding position in which they project partially outside the housings of the rotor 12.

Au contraire, lorsqu'une clé conforme est introduite à l'intérieur du rotor 12, les paillettes 32 sont entièrement escamotées radialement vers l'intérieur dans le rotor 12.On the contrary, when a suitable key is introduced inside the rotor 12, the flakes 32 are entirely retracted radially inwards in the rotor 12.

Ainsi, lorsque la clé conforme est introduite dans le rotor 12, celui-ci peut pivoter librement par rapport à la douille intermédiaire cylindrique 16 et par rapport au stator 14.Thus, when the correct key is introduced into the rotor 12, it can pivot freely relative to the cylindrical intermediate sleeve 16 and relative to the stator 14.

Au contraire, si on introduit dans le rotor 12 une clé non conforme, ou tout autre outil, les paillettes 34 ne sont pas entièrement escamotées et sont reçues à l'intérieur de fenêtres correspondantes 36 agencées dans la douille intermédiaire 16. Ainsi, les paillettes 34 immobilisent en rotation le rotor 12 par rapport à la douille intermédiaire 16 qui, elle, reste libre en rotation par rapport au stator 14.On the other hand, if a non-compliant key or any other tool is introduced into the rotor 12, the flakes 34 are not entirely retracted and are received inside corresponding windows 36 arranged in the intermediate bushing 16. Thus, the flakes 34 immobilize in rotation the rotor 12 relative to the intermediate sleeve 16 which itself remains free in rotation with respect to the stator 14.

L'indexeur 28 mobile axialement entre une position de repos et une position de débrayage est lié en translation sur le stator 14 par l'intermédiaire de rainures agencées à l'intérieur du stator et de nervures 38A, 38B coulissant à l'intérieur de ces rainures et entourant la douille intermédiaire 16. Les nervures 38A, 38B et les rainures sont au nombre de deux et sont diamétralement opposées.The indexer 28 movable axially between a rest position and a disengagement position is translationally connected to the stator 14 by means of grooves arranged inside the stator and ribs 38A, 38B sliding inside these grooves and surrounding the intermediate sleeve 16. The ribs 38A, 38B and the grooves are two in number and are diametrically opposed.

L'indexeur 28 comporte notamment un anneau principal 38 et des premières pattes de guidage 40 de forme trapézoïdale, en section par un plan tangentiel à l'anneau 38, qui s'étendent axialement vers l'avant à partir de l'anneau 38. Ces premières pattes 40 sont destinées à être reçues dans des encoches axiales correspondantes 42 de la douille intermédiaire 16. Ces premières pattes de guidage 40 sont au nombre de deux et sont diamétralement opposées sur l'anneau 38.The indexer 28 comprises in particular a main ring 38 and first trapezoidal guide lugs 40, in section through a plane tangential to the ring 38, which extend axially forwardly from the ring 38. These first lugs 40 are intended to be received in corresponding axial slots 42 of the intermediate bushing 16. These first guide lugs 40 are two in number and are diametrically opposite on the ring 38.

Les encoches 42 débouchent axialement vers l'arrière dans l'extrémité axiale arrière de la douille 16 de sorte que, avec les pattes de guidage 40, elles permettent d'assurer la liaison en rotation de l'indexeur 28 avec la douille intermédiaire 16, tout en laissant subsister la possibilité pour l'indexeur 28 de se déplacer axialement dans le verrou 10.The notches 42 open axially towards the rear in the rear axial end of the bushing 16 so that, with the guide tabs 40, they make it possible to ensure the rotational connection of the indexer 28 with the intermediate bushing 16, while leaving the possibility for the indexer 28 to move axially in the lock 10.

L'indexeur comporte également des secondes pattes de guidage 41 de forme rectangulaire, en section par un plan tangentiel à l'anneau 38, qui s'étendent axialement vers l'arrière à partir de l'anneau 38. Ces secondes pattes 41 sont destinées à être reçues dans des encoches axiales correspondantes 43 de la batteuse 24. Ces secondes pattes de guidage 41 sont au nombre de deux, sont diamétralement opposées sur l'anneau 38 et sont disposées sensiblement en face des premières pattes de guidage 40.The indexer also comprises second guide lugs 41 of rectangular shape, in section through a plane tangential to the ring 38, which extend axially rearwardly from the ring 38. These second lugs 41 are intended to be received in corresponding axial slots 43 of the thresher 24. These second guide lugs 41 are two in number, are diametrically opposite on the ring 38 and are arranged substantially opposite the first guide lugs 40.

L'entraîneur 26 assure l'accouplement du rotor 12 et de la batteuse 24, lorsque la clé est conforme. Il est lié en translation sur le rotor par l'intermédiaire de nervures internes 26A et de rainures 12A portées par le rotor 12.The driver 26 ensures the coupling of the rotor 12 and the thresher 24, when the key is compliant. It is linked in translation on the rotor by means of internal ribs 26A and grooves 12A carried by the rotor 12.

Les nervures internes 26A sont encastrées dans les rainures correspondantes 12A du rotor, en position embrayée, ces rainures étant ouvertes vers l'arrière du rotor 12 sur un tronçon cylindrique de diamètre inférieur au diamètre interne de l'entraîneur.The internal ribs 26A are embedded in the corresponding grooves 12A of the rotor, in the engaged position, these grooves being open towards the rear of the rotor 12 on a cylindrical section of diameter less than the internal diameter of the driver.

L'entraîneur 26 comporte un manchon 39 de diamètre intérieur ou intérieur sensiblement égal au diamètre extérieur ou intérieur de l'anneau 38 de l'indexeur 28, l'indexeur et l'entraîneur étant disposés bout à bout.The driver 26 comprises a sleeve 39 of inner or inner diameter substantially equal to the outer diameter or inside of the ring 38 of the indexer 28, the indexer and the driver being arranged end to end.

L'entraîneur 26 comporte des brides de guidage 45 de forme rectangulaire, en section par un plan tangentiel au manchon 39, qui s'étendent axialement vers l'arrière à partir du manchon 39. Ces brides de guidage 45 sont destinées à être reçues dans des encoches axiales correspondantes 47 de la batteuse 24, ces encoches permettant une translation vers la batteuse de l'entraîneur à l'encontre de l'effort du ressort de compression 30 et, avantageusement étant ouvertes sur la face frontale arrière de la batteuse. Ces brides de guidage 45 sont au nombre de deux, sont diamétralement opposées sur le manchon 39.The driver 26 comprises guide flanges 45 of rectangular shape, in section through a plane tangential to the sleeve 39, which extend axially rearwardly from the sleeve 39. These guide flanges 45 are intended to be received in corresponding axial notches 47 of the thresher 24, these notches allowing a translation to the thresher of the driver against the force of the compression spring 30 and advantageously being open on the rear end face of the thresher. These guide flanges 45 are two in number, are diametrically opposite on the sleeve 39.

Le verrou 10 comporte également un ressort de rappel 50 fonctionnant en torsion et servant au rappel de la batteuse 24 en position initiale.The latch 10 also comprises a return spring 50 operating in torsion and serving to return the thresher 24 to the initial position.

Le fonctionnement du verrou conforme à l'invention va maintenant être décrit en référence aux autres figures.The operation of the lock according to the invention will now be described with reference to the other figures.

Sur la figure 8, une clé conforme a été introduite dans le rotor 12 par l'entrée de clé 18 et le verrou est donc en position embrayée. Les paillettes 32 sont donc escamotées à l'intérieur du rotor 12 qui peut tourner dans la douille intermédiaire 16.On the figure 8 a correct key has been introduced into the rotor 12 by the key input 18 and the lock is thus in the engaged position. The flakes 32 are thus retracted inside the rotor 12 which can rotate in the intermediate bushing 16.

Dans cette position, le rotor 12 peut être tourné avec la clé et entraîne avec lui l'entraîneur 26 qui par l'emboîtement de ses brides 45 dans les encoches correspondantes 47 de la batteuse 24 entraîne cette dernière en rotation, libérant la serrure.In this position, the rotor 12 can be turned with the key and carries with it the driver 26 which by the engagement of its flanges 45 in the corresponding notches 47 of the thresher 24 drives the latter in rotation, releasing the lock.

Les autres pièces restent immobiles, plus précisément la douille intermédiaire 16 immobile en rotation et liée au stator 14 par la bille 60 et l'indexeur 28 emboîté dans cette dernière par l'intermédiaire de ses pattes de guidage avant 40.The other parts remain stationary, more precisely the intermediate sleeve 16 immobile in rotation and connected to the stator 14 by the ball 60 and the indexer 28 fitted into the latter through its front guide tabs 40.

La rotation de la batteuse 24 est obtenue par la rotation des pièces suivantes : clé / rotor / entraîneur / batteuse.The rotation of the thresher 24 is obtained by the rotation of the following parts: key / rotor / trainer / thresher.

En fin de course, lorsque la clé est lâchée, le ressort de rappel 50 dont une extrémité est fixe et une autre extrémité en butée contre une bride 24A de la batteuse 24, fait revenir la batteuse en position initiale ainsi que l'entraîneur et le rotor.At the end of the race, when the key is released, the return spring 50, one end of which is fixed and another end in abutment against a flange 24A of the thresher 24, returns the thresher to its initial position as well as the driver and the rotor.

Sur les figures 9 à 11, une clé non conforme a été introduite dans le rotor 12 par l'entrée de clé 18 et le verrou est donc en position débrayée. Les paillettes 32 ne sont donc pas escamotées à l'intérieur du rotor 12 qui est en conséquence lié en rotation à la douille intermédiaire 16, par encastrement des paillettes dans cette dernière.On the Figures 9 to 11 , a non-compliant key has been introduced into the rotor 12 by the key input 18 and the lock is thus in the disengaged position. The flakes 32 are therefore not retracted inside the rotor 12 which is consequently rotatably connected to the intermediate bushing 16, by embedding the flakes in the latter.

La rotation de la clé non conforme entraîne donc en rotation le rotor 12 et la douille intermédiaire 16 liés et entraînant la bille 60 dans l'orifice 16A de la douille intermédiaire 16A et dans la cavité 12B du rotor 12. La rotation de la douille 16 entraîne la translation de l'indexeur 28 en direction de la batteuse 24, par glissement des pattes de guidages avant 40 de l'indexeur hors des encoches correspondantes 42 de la douille 16. Dans cette position translatée, les pattes de guidage arrière 41 de l'indexeur 28 viennent s'encastrer dans les encoches 43 correspondantes de la batteuse 24. L'indexeur 28 étant immobile en rotation par sa liaison avec le stator, la batteuse ne peut tourner.The rotation of the non-compliant key therefore rotates the rotor 12 and the intermediate sleeve 16 connected and driving the ball 60 in the hole 16A of the intermediate sleeve 16A and in the cavity 12B of the rotor 12. The rotation of the sleeve 16 causes the indexer 28 to travel in the direction of the thresher 24, by sliding the front guide lugs 40 of the indexer out of the corresponding notches 42 of the bushing 16. In this translated position, the rear guide lugs 41 of the indexer 28 are embedded in the corresponding notches 43 of the thresher 24. The indexer 28 being rotatably immobilized by its connection with the stator, the thresher can not rotate.

L'entraîneur 26 est quant à lui désolidarisé du rotor 12, car il est poussé à l'encontre de l'effort du ressort de compression 30 par l'indexeur 28 qui appuie sur la face frontale avant. Ses nervures 26A sortent donc des encoches correspondantes 12A du rotor et le liaison en rotation du rotor et de l'entraîneur est supprimée.The driver 26 is in turn disengaged from the rotor 12 because it is pushed against the force of the compression spring 30 by the indexer 28 which bears on the front end face. Its ribs 26A therefore leave corresponding slots 12A of the rotor and the rotational connection of the rotor and the driver is removed.

Dans cette position débrayée, lors de la rotation d'une clé non conforme, la bille lie en rotation la douille intermédiaire 16 et le rotor 12, c'est-à-dire est encastrée dans la cavité 12B externe du rotor.In this disengaged position, during the rotation of a non-compliant key, the ball links in rotation the intermediate sleeve 16 and the rotor 12, that is to say is embedded in the outer cavity 12B of the rotor.

La rotation volontaire de la clé entraîne donc le déplacement des pièces suivantes : rotation du rotor / rotation de la douille intermédiaire / translation de l'indexeur et blocage en rotation de la batteuse / translation de l'entraîneur et désolidarisation de la batteuse.The voluntary rotation of the key therefore causes the following parts to move: rotation of the rotor / rotation of the intermediate bushing / translation of the indexer and blockage in rotation of the threshing machine / translation of the driver and disconnection of the threshing machine.

Lors de l'introduction ultérieure d'une clé conforme , le rotor 12 est tourné grâce à la rotation de la clé jusqu'à la position initiale représentée sur les figures 2 à 7, la bille 60 étant désolidarisée du rotor, puis le verrou est embrayé si la clé est conforme ou est débrayée si la clé n'est pas conforme.At the subsequent introduction of a suitable key, the rotor 12 is rotated by the rotation of the key to the initial position shown on the Figures 2 to 7 , the ball 60 being disengaged from the rotor, then the lock is engaged if the key is compliant or is disengaged if the key is not compliant.
