Description

La présente invention concerne un procédé de fabrication d'un stator de verrou rotatif pour système de verrouillage de véhicule automobile et un verrou fabriqué par un tel procédé.The present invention relates to a method of manufacturing a rotary latch stator for a motor vehicle locking system and a latch manufactured by such a method.

Plus particulièrement, l'invention concerne un stator de verrou rotatif à monter sur un ouvrant de véhicule automobile pour les mécanismes de serrure, notamment pour une portière, un hayon, une lunette de hayon, un coffre, une boîte à gant ou encore pour un bouchon de réservoir de carburant de véhicule. Un tel verrou et en particulier stator de verrou est par exemple connu du document EP1026343 .More particularly, the invention relates to a rotary latch stator to be mounted on an opening of a motor vehicle for the lock mechanisms, in particular for a door, a tailgate, a tailgate bezel, a trunk, a glove box or for a vehicle fuel tank cap. Such a lock and in particular bolt stator is for example known from the document EP1026343 .

L'invention s'applique également aux verrous de commutateur électrique rotatif pour antivol de véhicule automobile.The invention also applies to rotary electrical switch locks for a motor vehicle lock.

Les verrous rotatifs comportent un stator à l'intérieur duquel un rotor est susceptible d'être mobile en rotation lorsque la clef conforme au verrou est insérée de manière à décondamner le système de verrouillage du véhicule automobile.The rotary locks comprise a stator inside which a rotor is able to be rotatable when the key according to the lock is inserted so as to unlock the locking system of the motor vehicle.

Dans la plupart des cas, les stators sont réalisés d'une seule pièce.In most cases, the stators are made in one piece.

Toutefois, dans certaines applications spécifiques, il est nécessaire que le stator se présente en deux parties complémentaires aptes à s'assembler. Les verrous comportent alors des moyens de fixation permettant de solidariser rigidement ensemble les deux parties du stator.However, in some specific applications, it is necessary that the stator is in two complementary parts suitable for assembly. The locks then comprise fixing means for rigidly securing together the two parts of the stator.

Ces moyens de fixation sont constitués de goupilles cylindriques, élastiques ou à vis, à même d'être insérées dans des trous ménagés à travers les deux parties du stator et positionnés en regard les uns des autres.These fixing means consist of cylindrical pins, elastic or screw, able to be inserted into holes formed through the two parts of the stator and positioned opposite one another.

Cette structure est suffisamment rigide pour garantir l'intégrité du verrou, notamment en cas d'arrachement ou d'enfoncement du rotor.This structure is rigid enough to ensure the integrity of the lock, especially in case of tearing or sinking of the rotor.

On cherche cependant un moyen alternatif pour assembler solidement les deux pièces formant le stator, permettant de réduire les coûts et les risques qualitatifs de fabrication tout en garantissant l'intégrité du verrou.However, we seek an alternative way to securely assemble the two parts forming the stator, to reduce the costs and quality of manufacturing risks while ensuring the integrity of the lock.

La présente invention vise à remédier à ce problème en proposant un procédé de fabrication d'un stator de verrou rotatif pour système de verrouillage de véhicule automobile comprenant au moins une première partie et une deuxième partie complémentaires, aptes à s'assembler dans au moins une zone de recouvrement pour former le stator à l'intérieur duquel un rotor est susceptible d'être mobile en rotation, caractérisé en ce qu'il comporte les étapes suivantes :

  • une première étape d'assemblage desdites deux parties, de façon à positionner dans la zone de recouvrement au moins un orifice ménagé dans la première partie du stator face à l'ouverture d'une cavité correspondante ménagée dans la deuxième partie du stator,
  • une seconde étape de sertissage au cours de laquelle on introduit un poinçon de sertissage dans chaque orifice pour déformer au moins partiellement la paroi de l'orifice en direction de la cavité correspondante de façon à sertir l'assemblage des deux parties du stator.
The present invention aims to remedy this problem by proposing a method of manufacturing a rotary latch stator for a motor vehicle locking system comprising at least a first part and a second complementary part, able to assemble in at least one covering zone for forming the stator inside which a rotor is able to be rotatable, characterized in that it comprises the following steps:
  • a first assembly step of said two parts, so as to position in the overlap zone at least one orifice formed in the first part of the stator facing the opening of a corresponding cavity formed in the second part of the stator,
  • a second crimping step during which a crimping punch is introduced into each orifice to at least partially deform the wall of the orifice in the direction of the corresponding cavity so as to crimp the assembly of the two parts of the stator.

L'invention a également pour objet un stator de verrou rotatif pour système de verrouillage de véhicule automobile comprenant au moins une première et une deuxième partie, assemblées dans au moins une zone de recouvrement à l'intérieur duquel un rotor est susceptible d'être mobile en rotation, caractérisé en ce qu'il comporte au moins un orifice ménagé dans une première partie du stator positionné face à l'ouverture d'une cavité correspondante ménagée dans une deuxième partie du stator, la paroi de l'orifice ayant été déformée au moins partiellement par l'introduction d'un poinçon de sertissage en direction de la cavité correspondante, de façon à sertir les deux parties du stator.The invention also relates to a rotary latch stator for a motor vehicle locking system comprising at least a first and a second part, assembled in at least one overlap zone inside which a rotor is likely to be movable. in rotation, characterized in that it comprises at least one orifice formed in a first portion of the stator positioned facing the opening of a corresponding cavity formed in a second portion of the stator, the wall of the orifice having been deformed at the less partially by the introduction of a crimping punch towards the corresponding cavity, so as to crimp the two parts of the stator.

La figure 1 représente différents éléments d'un verrou rotatif pour système de verrouillage de véhicule automobile selon l'invention.The figure 1 represents various elements of a rotary latch for a motor vehicle locking system according to the invention.

Il est entendu que l'invention s'applique à tout type de verrou rotatif composé d'un rotor et d'un stator tel qu'un verrou d'ouvrant de véhicule automobile ou un verrou de commutateur électrique rotatif pour antivol de véhicule automobile.It is understood that the invention applies to any type of rotary latch composed of a rotor and a stator such as a motor vehicle door latch or a rotary electric switch lock for a motor vehicle lock.

Plus particulièrement, l'invention s'applique aux verrous à monter sur ouvrant de véhicule automobile pour les mécanismes de serrure, notamment pour une portière telle qu'à poignée d'ouverture mobile ou à poignée fixe, un hayon, une lunette de hayon, un coffre, une boîte à gant ou encore pour un bouchon de réservoir de carburant de véhicule.More particularly, the invention applies to locks for mounting on a motor vehicle door for the lock mechanisms, in particular for a door such as a movable opening handle or fixed handle, a tailgate, a tailgate bezel, a trunk, a glove box or for a vehicle fuel tank cap.

La figure 1 illustre un système de verrouillage de porte de véhicule automobile comportant un support 1 servant de socle d'ancrage à une poignée d'ouverture extérieure, ainsi qu'à un verrou rotatif de condamnation 10.The figure 1 illustrates a motor vehicle door locking system comprising a support 1 serving as anchoring base for an external opening handle, as well as a rotary locking latch 10.

Dans ce mode de réalisation, la poignée mobile est actionnable manuellement depuis l'extérieur du véhicule. L'ensemble est classiquement agencé de manière à ce que la mobilité de la poignée soit en mesure de commander un mécanisme de serrure associé à une porte (non représentée).In this embodiment, the movable handle is manually operable from outside the vehicle. The set is classically arranged so that the mobility of the handle is able to control a lock mechanism associated with a door (not shown).

Le verrou 10 destiné à condamner l'ouverture de la porte est de type rotatif, c'est-à-dire qu'il est composé d'un rotor 11 susceptible d'être mobile en rotation axiale à l'intérieur d'un stator 12 lorsque la clef conforme au verrou 10 est insérée dans l'entrée de clé 13 ménagée à l'extrémité du rotor 11, de manière à décondamner le système de verrouillage du véhicule automobile.The lock 10 intended to block the opening of the door is of rotary type, that is to say that it is composed of a rotor 11 capable of being movable in axial rotation within a stator 12 when the key according to the latch 10 is inserted into the key inlet 13 formed at the end of the rotor 11, so as to unlock the locking system of the motor vehicle.

Il est entendu que, dans l'ensemble de ce texte, le terme rotor désigne très généralement tout sous-ensemble comprenant un corps de rotor à travers lequel sont ménagés des logements radiaux à même de recevoir des paillettes qui sont montées mobiles en translation radiale et qui sont couplées à des ressorts de rappel les entraînant en permanence dans des positions saillantes par rapport au corps du rotor.It is understood that throughout this text, the term rotor designates very generally any subassembly comprising a rotor body through which are formed radial housings able to receive flakes which are movably mounted in radial translation and which are coupled to return springs permanently driving them into protruding positions with respect to the rotor body.

Le verrou 10 est implanté au niveau du support 1, de telle sorte que l'entrée de clé 13 ménagée à l'extrémité du rotor 11 soit accessible depuis l'extérieur du véhicule automobile.The latch 10 is located at the support 1, so that the key inlet 13 formed at the end of the rotor 11 is accessible from outside the motor vehicle.

Le support 1 peut être solidarisé à la porte par au moins une vis d'assemblage qui est apte, d'une part, à être insérée dans un trou ménagé à travers un panneau de la porte, et d'autre part, à coopérer avec un alésage taraudé 15 ménagé dans une partie du support 1.The support 1 can be secured to the door by at least one assembly screw which is able, on the one hand, to be inserted into a hole formed through a panel of the door, and on the other hand, to cooperate with a tapped bore 15 formed in a part of the support 1.

Une portion du support 1 forme le stator 12 en délimitant un logement 2 qui est en mesure de recevoir le rotor 11 du verrou 10.A portion of the support 1 forms the stator 12 delimiting a housing 2 which is able to receive the rotor 11 of the lock 10.

Le logement 2 présente une forme sensiblement cylindrique, étant donné que la portion du support 1 qui la délimite a pour fonction de constituer le stator 12 du verrou 10, c'est-à-dire de guider la rotation axiale du rotor 11 du verrou 10.The housing 2 has a substantially cylindrical shape, since the portion of the support 1 which delimits it has the function of constituting the stator 12 of the lock 10, that is to say to guide the axial rotation of the rotor 11 of the lock 10 .

Par ailleurs, le support 1 comporte des moyens de butée 20 qui sont en mesure de bloquer, en translation axiale, le rotor 11 du verrou 10 à l'intérieur dudit logement 2. La présence des moyens de butée 20 s'avère indispensable pour assurer un maintien omnidirectionnel du rotor 11 du verrou 10, et ainsi garantir que la portion du support 1, qui délimite le logement 2, soit en mesure de jouer pleinement son rôle de stator.Furthermore, the support 1 comprises stop means 20 which are able to block, in axial translation, the rotor 11 of the lock 10 inside said housing 2. The presence of the abutment means 20 is essential to ensure omnidirectional support of the rotor 11 of the lock 10, and thus guarantee that the portion of the support 1, which delimits the housing 2, is able to play its role of stator fully.

Cette caractéristique permet également d'accroître significativement la tenue mécanique de l'ensemble, notamment vis-à-vis d'éventuelles tentatives d'effraction par arrachage ou défoncement du rotor 11.This characteristic also makes it possible to significantly increase the mechanical strength of the assembly, particularly with respect to possible attempts of burglary by tearing or breaking the rotor 11.

Dans cet exemple de réalisation, ce sont les deux extrémités du logement 2 qui sont ouvertes, puisqu'une ouverture avant est prévue pour assurer l'accès à l'entrée de clé 13 du rotor 11, tandis qu'une ouverture arrière est nécessaire pour permettre le passage d'un classique élément de liaison 14 destiné à être couplé au mécanisme de serrure de la porte.In this embodiment, it is the two ends of the housing 2 which are open, since a front opening is provided to provide access to the key entry 13 of the rotor 11, while a rear opening is necessary to allow the passage of a conventional connecting element 14 to be coupled to the lock mechanism of the door.

Ainsi qu'on peut le voir clairement toujours sur la figure 1, les moyens de butée 20 sont ici concrètement constitués par des nervures saillantes. Chacune d'entre elles est ménagée à proximité d'une des extrémités ouvertes du logement 2, sur la surface interne de la portion du support 1 qui délimite le logement 2.As can be seen clearly still on the figure 1 the abutment means 20 are here concretely constituted by projecting ribs. Each of them is formed near one of the open ends of the housing 2, on the inner surface of the portion of the support 1 which defines the housing 2.

Le logement 2 est défini par la juxtaposition de deux parois semi-cylindriques 3, 4 qui sont respectivement ménagées sur des éléments constitutifs distincts du support 1, dits parties 5, 6 ; chaque partie 5, 6 étant destinée à être assemblée radialement avec l'autre partie de stator complémentaire dans au moins une zone de recouvrement 7 pour former le stator 12 du verrou 10 à l'intérieur duquel un rotor 11 est susceptible d'être mobile en rotation.The housing 2 is defined by the juxtaposition of two semi-cylindrical walls 3, 4 which are respectively formed on separate constituent elements of the support 1, said parts 5, 6; each part 5, 6 being intended to be assembled radially with the other complementary stator part in at least one overlap area 7 to form the stator 12 of the lock 10 inside which a rotor 11 is able to be movable in rotation.

Dans ce mode de réalisation, la partie de stator 6 représentée à gauche sur la figure 1 recouvre la partie de stator 5 représentée à droite dans deux zones de recouvrement 7a, 7b symétriques au plan général du support 1.In this embodiment, the stator portion 6 shown to the left on the figure 1 covers the stator portion 5 shown to the right in two overlapping zones 7a, 7b symmetrical to the general plane of the support 1.

Les deux zones de recouvrement 7a, 7b sont formées par des pattes de liaison portées par les extrémités de la partie de stator gauche 6 recouvrant des embases portées par les extrémités de la partie de stator droit 5 lorsque les deux parties de stator 5, 6 sont assemblées.The two overlapping zones 7a, 7b are formed by connecting tabs carried by the ends of the left stator part 6 covering bases carried by the ends of the right stator part 5 when the two stator parts 5, 6 are assemblies.

Cette caractéristique permet de pouvoir monter le rotor 11 à l'intérieur du logement 2, même lorsque comme précédemment décrit, le support 1 est conformé de manière à garantir l'immobilité en translation axiale du rotor 11.This characteristic makes it possible to mount the rotor 11 inside the housing 2, even when, as previously described, the support 1 is shaped so as to guarantee the immobility in axial translation of the rotor 11.

L'ensemble est agencé de façon à ce que lors de l'assemblage des différents parties 5, 6, les deux parois semi-cylindriques correspondantes 3, 4 viennent se positionner en regard les unes des autres, et constituer ainsi le logement 2 dont la forme et les dimensions sont choisies pour maintenir et guider en rotation axiale le rotor 11 du verrou 10.The assembly is arranged so that during the assembly of the different parts 5, 6, the two corresponding semi-cylindrical walls 3, 4 are positioned opposite one another, and thus constitute the housing 2 whose shape and dimensions are chosen to maintain and guide in axial rotation the rotor 11 of the lock 10.

Dans ce mode particulier de réalisation, le logement 2 est défini par la juxtaposition d'uniquement deux parois semi-cylindriques 3, 4 qui sont de formes sensiblement identiques.In this particular embodiment, the housing 2 is defined by the juxtaposition of only two semi-cylindrical walls 3, 4 which are substantially identical shapes.

Dans un second mode de réalisation illustré par la figure 3, le logement 2 est également défini par la juxtaposition d'uniquement deux parties de stator 5, 6 complémentaires s'assemblant radialement.In a second embodiment illustrated by the figure 3 , the housing 2 is also defined by the juxtaposition of only two complementary stator parts 5, 6 joining radially.

La partie de stator 6 représentée à droite sur la figure 3 recouvre la partie de stator 5 représentée à gauche dans quatre zones de recouvrement 7a, 7b (non visible), 7c et 7d.The stator portion 6 shown to the right on the figure 3 covers the stator portion 5 shown to the left in four overlapping zones 7a, 7b (not visible), 7c and 7d.

Les quatre zones de recouvrement 7a, 7b, 7c, 7d portées par la partie de support droit 6 forment quatre pattes de liaison, dont deux 7a et 7b sont diamétralement opposées et positionnées sur l'extrémité du rotor 11 comportant l'entrée de clé de serrure 13. Deux autres zones de recouvrement 7c et 7d également diamétralement opposées sont positionnées sur l'extrémité opposée du rotor 11.The four overlapping zones 7a, 7b, 7c, 7d carried by the right support portion 6 form four connecting lugs, two of which 7a and 7b are diametrically opposed and positioned on the end of the rotor 11 having the key input. lock 13. Two other overlapping zones 7c and 7d, also diametrically opposed, are positioned on the opposite end of the rotor 11.

Les quatre zones de recouvrement 7a, 7b, 7c, 7d correspondantes portées par la partie de support gauche 5 sont formées par quatre faces de liaison.The four overlapping areas 7a, 7b, 7c, 7d corresponding carried by the left support portion 5 are formed by four connecting faces.

Dans un troisième mode de réalisation illustré sur les figures 4a et 4b, le logement 2 est défini par l'assemblage axial de deux parties de stator 5, 6 radialement complémentaires.In a third embodiment illustrated on the Figures 4a and 4b , the housing 2 is defined by the axial assembly of two stator portions 5, 6 radially complementary.

Dans ce mode de réalisation, il est nécessaire, pour pouvoir monter l'ensemble des composants internes à l'intérieur du verrou 10 que le stator 12 se présente sous la forme de deux parties 5, 6 à même d'être assemblées par emboîtement axial dans la zone de recouvrement 7.In this embodiment, it is necessary, in order to mount all the internal components inside the latch 10 that the stator 12 is in the form of two parts 5, 6 able to be assembled by axial interlocking in the overlap area 7.

Le stator 12 est alors composé d'une partie de stator avant 6 entourant l'entrée de clé 13 du rotor 11, ainsi que d'une partie de stator arrière 5, qui sont sensiblement tubulaires et radialement complémentaires.The stator 12 is then composed of a front stator portion 6 surrounding the key inlet 13 of the rotor 11, as well as a rear stator portion 5, which are substantially tubular and radially complementary.

Avantageusement, la partie de stator avant 6 recouvre la partie de stator arrière 5 dans deux zones de recouvrement 7a et 7b.Advantageously, the front stator portion 6 covers the rear stator portion 5 in two overlapping zones 7a and 7b.

Une première zone de recouvrement 7a est formée par l'engagement d'une patte de la partie de stator arrière 5 dans un conduit porté par la partie de stator avant 6.A first lap region 7a is formed by engaging a tab of the rear stator portion 5 in a conduit carried by the front stator portion 6.

Une deuxième zone de recouvrement 7b est formée par le recouvrement d'une face inférieure coulissante de partie de stator arrière 5 par une face supérieure coulissante de partie de stator avant 6.A second overlap area 7b is formed by overlapping a rear lower portion of the rear stator portion 5 by a front upper stator portion sliding front surface 6.

Pour l'ensemble des formes de réalisation de stator 12 de verrou 10 en deux parties, telles que celles décrites précédemment, l'invention propose un procédé de fabrication comportant une première étape d'assemblage suivie d'une seconde étape de sertissage permettant d'assembler et de sertir les deux parties du stator 5, 6 entre elles pour obtenir le verrou 10 selon l'invention.For all embodiments of stator 12 lock 10 in two parts, such as those described above, the invention provides a manufacturing method comprising a first assembly step followed by a second crimping step allowing assembling and crimping the two parts of the stator 5, 6 together to obtain the lock 10 according to the invention.

Pour cela, une première partie de stator 6 comporte au moins deux orifices 32 dans la zone de recouvrement 7.For this, a first stator portion 6 comprises at least two orifices 32 in the overlap area 7.

Chaque orifice 32 comporte une portion de paroi 23 susceptible d'être déformée par l'introduction d'un poinçon de sertissage 22.Each orifice 32 has a wall portion 23 that can be deformed by the introduction of a crimping punch 22.

De préférence, chaque zone de recouvrement comporte un orifice.Preferably, each overlap zone comprises an orifice.

On peut également envisager que deux orifices soient ménagés dans la partie de stator avant 6 dans chacune des deux zones de recouvrement 7a, 7b, comme illustré dans le mode de réalisation particulier de la figure 4a.It can also be envisaged that two orifices are formed in the front stator portion 6 in each of the two overlapping zones 7a, 7b, as illustrated in the particular embodiment of FIG. figure 4a .

Ainsi, deux orifices 32 sont prévus latéralement et symétriquement dans deux faces latérales opposées du conduit de la première zone de recouvrement 7a et deux orifices 32 sont prévus latéralement et symétriquement dans deux faces latérales opposées d'une face supérieure coulissante de la deuxième zone de recouvrement 7b.Thus, two orifices 32 are provided laterally and symmetrically in two opposite lateral faces of the duct of the first zone of overlap 7a and two orifices 32 are provided laterally and symmetrically in two opposite lateral faces of a sliding upper face of the second overlap zone 7b.

De préférence, les orifices 32 prévus dans le conduit sont situés proches de l'extrémité comportant l'entrée de clef 13 de sorte qu'ils soient longitudinalement décalés avec les orifices 32 prévus dans la face supérieure coulissante.Preferably, the orifices 32 provided in the duct are located near the end comprising the key inlet 13 so that they are longitudinally offset with the orifices 32 provided in the sliding upper face.

D'autre part, pour l'ensemble des modes de réalisation, la partie de stator 5 destinée à être assemblée avec la partie de stator complémentaire 6 comporte au moins deux cavités 34 dans la zone de recouvrement.On the other hand, for all the embodiments, the stator portion 5 intended to be assembled with the complementary stator portion 6 comprises at least two cavities 34 in the overlap zone.

La position et les dimensions des cavités correspondent à celles des orifices 32 de sorte qu'une fois les parties de stator 5, 6 assemblées, d'une part, une portion de paroi 23 de chaque orifice 32 est positionnée face à l'ouverture de la cavité 34 correspondante et d'autre part, les cavités soient aptes à recevoir les portions de paroi 23 déformées des orifices 32.The position and the dimensions of the cavities correspond to those of the orifices 32 so that once the stator parts 5, 6 are assembled, on the one hand, a wall portion 23 of each orifice 32 is positioned facing the opening of the corresponding cavity 34 and, on the other hand, the cavities are able to receive the deformed wall portions 23 of the orifices 32.

Puis, dans la première étape d'assemblage des deux parties 5, 6 de stator, on positionne une portion de paroi 23 de chaque orifice 32 face à l'ouverture d'une cavité 34 correspondante.Then, in the first step of assembling the two parts 5, 6 of the stator, positioning a wall portion 23 of each orifice 32 facing the opening of a corresponding cavity 34.

Ainsi, on assemble les deux parties de stator 5, 6 comme Indiqué sur les figures 1, 3 et 4a par les flèches 24 et 25 de manière à bien positionner les portions de paroi 23 de chaque orifice 32 face aux ouvertures de cavité 34 correspondantes.Thus, we assemble the two parts of stator 5, 6 as indicated on the figures 1 , 3 and 4a by the arrows 24 and 25 so as to properly position the wall portions 23 of each orifice 32 facing the corresponding cavity openings 34.

Ensuite, dans la seconde étape de sertissage, on introduit un poinçon de sertissage 22 dans chaque orifice 32 pour déformer les portions de paroi 23 en direction des cavités 34 de façon à sertir l'assemblage des deux parties du stator 5, 6.Then, in the second crimping step, a crimping punch 22 is introduced into each orifice 32 to deform the wall portions 23 in the direction of the cavities 34 so as to crimp the assembly of the two parts of the stator 5, 6.

La direction du poinçon de sertissage 22 dans chaque orifice 32 est indiquée sur les figures 1, 3 et 4a par les flèches 26.The direction of the crimping punch 22 in each orifice 32 is indicated on the figures 1 , 3 and 4a by the arrows 26.

Selon une première variante de procédé et de manière avantageuse, les orifices 32 sont borgnes et c'est la paroi de fond de chaque orifice 32 borgne qui forme la portion de paroi 23 susceptible d'être positionnée face à l'ouverture de la cavité correspondante au cours de la première étape d'assemblage et susceptible d'être déformée au cours de la deuxième étape de sertissage.According to a first variant of the method and advantageously, the orifices 32 are blind and this is the bottom wall of each orifice 32 blind that forms the wall portion 23 may be positioned facing the opening of the corresponding cavity during the first assembly step and may be deformed during the second crimping step.

Une alternative à cette variante de procédé propose des orifices 32 traversants. Les parois latérales de chaque orifice 32 traversant forment alors la portion de paroi 23 susceptible d'être positionnée face à l'ouverture de la cavité 34 correspondante au cours de la première étape d'assemblage.An alternative to this variant of the method proposes through orifices 32. The side walls of each through-orifice 32 then form the wall portion 23 capable of being positioned facing the opening of the corresponding cavity 34 during the first assembly step.

Dans cette alternative, la portion de paroi 23 est susceptible d'être déformée au cours de la deuxième étape de sertissage. Pour cela, les orifices 32 traversants possèdent une ouverture de dimension plus petite que la dimension transversale de l'extrémité de déformation du poinçon de sertissage 22, de sorte que l'extrémité du poinçon de sertissage 22 emporte partiellement les parois latérales de l'orifice 32 dans la cavité 34.In this alternative, the wall portion 23 is likely to be deformed during the second crimping step. For this, the through orifices 32 have an opening smaller in size than the transverse dimension of the deformation end of the crimping punch 22, so that the end of the crimping punch 22 partially carries the side walls of the orifice 32 in the cavity 34.

Selon une seconde variante de procédé, on prévoit que le poinçon de sertissage 22 possède une extrémité de déformation de forme sensiblement plate pour déformer de façon discontinue la portion de paroi 23 dans la cavité 34 lors de la deuxième étape de sertissage.According to a second variant of the method, the crimping punch 22 has a deformation end of substantially flat shape to discontinuously deform the wall portion 23 in the cavity 34 during the second crimping step.

Cette variante est illustrée sur la figure 2a représentant deux parties de stator en cours de sertissage selon le mode de réalisation sensiblement équivalent de la figure 3.This variant is illustrated on the figure 2a showing two stator parts being crimped according to the substantially equivalent embodiment of the figure 3 .

La portion de paroi 23 est alors rompue formant un ergot dans la cavité 34 correspondante.The wall portion 23 is then broken forming a lug in the corresponding cavity 34.

Selon une alternative à cette variante représentée sur la figure 2b, le poinçon de sertissage 22 possède une extrémité de déformation de forme arrondie pour déformer de façon continue la portion de paroi 23 dans la cavité 34 lors de la deuxième étape de sertissage.According to an alternative to this variant represented on the figure 2b the crimping punch 22 has a rounded deformation end for continuously deforming the wall portion 23 in the cavity 34 during the second crimping step.

En sertissant avec cet outil, la portion de paroi 23 est déformée sans rupture par pénétration dans la cavité 34, augmentant la solidité du sertissage.Crimping with this tool, the wall portion 23 is deformed without breaking by penetration into the cavity 34, increasing the strength of the crimping.

On obtient alors un verrou 10 assemblé et serti tel que représenté sur la figure 4b pour lequel le nombre de pièces nécessaires à l'assemblage du stator 12 a été réduit.We then obtain a bolt 10 assembled and crimped as shown on the figure 4b for which the number of parts necessary for the assembly of the stator 12 has been reduced.

En effet, le procédé de fabrication selon l'invention ne nécessite plus l'introduction de goupilles supplémentaires évitant ainsi les risques de pertes lors du transport des pièces ou d'oubli et de pertes ou encore de mauvais positionnement des goupilles sur les parties de stator 5, 6 empêchant le montage ultérieur sur véhicule.Indeed, the manufacturing method according to the invention no longer requires the introduction of additional pins thus avoiding the risk of losses during the transport of parts or forgetting and loss or misplacement of the pins on the stator parts 5, 6 preventing subsequent mounting on the vehicle.

Les parties de stator 5, 6 de verrou 10 sont assemblées solidement de manière simple et automatisée.The stator parts 5, 6 of the lock 10 are securely assembled in a simple and automated manner.

Il en résulte une diminution significative des coûts de production et de montage.This results in a significant decrease in production and assembly costs.
