Description

"DISPOSITIF D'INDEXATION RELATIVE DES CANNELURES D'UN ARBRE PRIMAIRE D'UNE BOITE DE VITESSES ET D'UN MOYEU CENTRAL D'UN EMBRAYAGE DE MOTEUR POU R VEHICULE AUTOMOBILE" [0001 ] La présente invention concerne d'une manière générale la procédure d'accostage d'un moteur thermique et d'une boîte de vitesses pour un véhicule, tel qu'un véhicule automobile.  FIELD OF THE INVENTION [0001] The present invention relates in a general manner to the procedure for docking a heat engine and a gearbox for a vehicle, such as a motor vehicle.
[0002] Lors de la phase d'accostage d'un moteur thermique et de la boîte de vitesses mécanique en usine terminale, les cannelures de l'arbre primaire de la boîte de vitesses doivent s'engager avec les cannelures du moyeu central d'un embrayage à friction porté par le volant moteur du moteur thermique. During the docking phase of a thermal engine and the mechanical gearbox terminal factory, the splines of the primary shaft of the gearbox must engage with the splines of the central hub of a friction clutch carried by the engine flywheel of the engine.
[0003] Cependant, il peut arriver qu'un tel engagement soit difficile à réaliser et plusieurs méthodes ont déjà été proposées pour corriger ce défaut d'engagement. However, it may happen that such commitment is difficult to achieve and several methods have already been proposed to correct this lack of commitment.
[0004] Une première méthode consiste à un opérateur de manipuler la boîte de vitesses supportée par une grue d'atelier par l'intermédiaire d'élingues pour tenter d'engager les cannelures de l'arbre primaire de la boîte de vitesses dans les cannelures du moyeu d'embrayage de friction associé au moteur thermique reposant sur une table du poste d'accostage. A first method is for an operator to manipulate the gearbox supported by a workshop crane by means of slings in an attempt to engage the splines of the primary shaft of the gearbox in the grooves of the friction clutch hub associated with the heat engine resting on a table of the berth.
[0005] Cette méthode risque d'endommager le moyeu central cannelé de l'embrayage à friction pouvant générer une usure prématurée des cannelures et/ou un mauvais coulissement de l'arbre primaire de la boîte de vitesses en fonctionnement. This method may damage the splined central hub of the friction clutch may generate premature wear of the splines and / or improper sliding of the primary shaft of the gearbox in operation.
[0006] En outre, l'endommagement de ce moyeu peut amener le conducteur du véhicule à des difficultés de passage de vitesse. In addition, the damage to this hub can cause the driver of the vehicle to difficulties of passage of speed.
[0007] Selon une autre méthode, l'opérateur fait tourner manuellement l'arbre primaire de la boîte de vitesses portée par une grue d'atelier par l'intermédiaire d'élingues pour tenter d'engager les cannelures de l'arbre primaire dans les cannelures du moyeu central cannelé de l'embrayage à friction du moteur thermique reposant sur une table du poste d'accostage. [0008] Cette méthode a pour inconvénients de polluer et retirer la graisse déposée en usine mécanique sur les cannelures de l'arbre primaire, d'où un risque de corrosion pouvant générer une usure prématurée des cannelures et/ou un mauvais coulissement de l'arbre primaire en fonctionnement du véhicule. En outre, cette méthode peut occasionner un grippage de l'arbre primaire dans le moyeu d'embrayage à friction et/ou une pollution des garnitures de friction par centrifugation avec pour conséquence le patinage et l'usure prématurée des garnitures de friction de l'embrayage en fonctionnement du véhicule. [0007] In another method, the operator manually rotates the primary shaft of the gearbox carried by a workshop crane by means of slings in order to attempt to engage the splines of the primary shaft in the splines of the splined central hub of the friction clutch of the heat engine resting on a table of the berth. This method has the disadvantage of polluting and removing the grease deposited in the mechanical factory on the splines of the primary shaft, resulting in a risk of corrosion may cause premature wear of the grooves and / or poor sliding of the primary shaft in operation of the vehicle. In addition, this method can lead to jamming of the primary shaft in the friction clutch hub and / or pollution of the friction linings by centrifugation, resulting in slipping and premature wear of the friction linings of the clutch. clutch in operation of the vehicle.
[0009] Selon une troisième méthode plus sophistiquée, un opérateur utilise un outil permettant de faire tourner le différentiel de la boîte de vitesses mécanique qui est élinguée, l'outil étant différent suivant les usines terminales. According to a third more sophisticated method, an operator uses a tool for rotating the differential of the mechanical gearbox which is slung, the tool being different according to the terminal factories.
[0010] Plus précisément, cette méthode comprend les étapes de : More specifically, this method comprises the steps of:
1 / retirer l'obturateur de sortie différentiel gauche de la boîte de vitesses ; 1 / remove the left differential output shutter of the gearbox;
21 engager un rapport de vitesses de la boîte de vitesses, la boîte étant livrée en position neutre ; 3/ mettre en place l'outil de rotation du différentiel ; 21 engage a gear ratio of the gearbox, the box being delivered in neutral position; 3 / set up the differential rotation tool;
4/ effectuer une rotation du différentiel de la boîte de vitesses via l'outil qui, par le train d'engrenage, fait tourner l'arbre primaire de la boîte de vitesses ; 4 / rotation of the gearbox differential via the tool which, by the gear train, rotates the primary shaft of the gearbox;
5/ engager la boîte de vitesses sur le moteur ; 5 / engage the gearbox on the engine;
6/ retirer l'outil ; et 11 remettre en place l'obturateur de sortie du différentiel gauche. 6 / remove the tool; and 11 replace the output shutter of the left differential.
[001 1 ] Si l'engagement de la boîte de vitesses sur le moteur ne peut s'effectuer à cause du défaut d'engagement des cannelures de l'arbre primaire de la boîte de vitesses avec les cannelures du moyeu central de l'embrayage à friction, les étapes précédentes 4/ et 5/ doivent être renouvelées jusqu'à ce que l'engagement de la boîte de vitesses du moteur puisse s'effectuer correctement. [001 1] If the engagement of the gearbox on the engine can not take place because of the fault of engagement of the splines of the primary shaft of the gearbox with the splines of the central hub of the clutch with friction, the previous steps 4 / and 5 / must be renewed until the engagement of the gearbox of the engine can be carried out correctly.
[0012] Cette méthode est chronophage et peut occasionner un risque important d'endommagement du joint de sortie du différentiel gauche. En outre, cette méthode ne fonctionne pas pour les boîtes de vitesses mécaniques pilotées et à double embrayage car il n'est pas possible d'engager un rapport sans alimentation électrique. This method is time consuming and can cause a significant risk of damage to the left differential outlet seal. In addition, this method does not work for mechanical geared and dual clutch gearboxes because it is not possible to engage a gear without power supply.
[0013] Enfin, elle peut provoquer une fuite d'huile de la boîte de vitesses au niveau du joint de transmission lors du fonctionnement du véhicule. [0014] La présente invention a pour but de pallier les inconvénients des méthodes connues ci-dessus pour engager les cannelures de l'arbre primaire d'une boîte de vitesses dans les cannelures du moyeu central de l'embrayage à friction associé au moteur thermique pour un véhicule automobile. Finally, it can cause oil leakage of the gearbox at the transmission joint during operation of the vehicle. The present invention aims to overcome the disadvantages of known methods above to engage the splines of the primary shaft of a gearbox in the splines of the central hub of the friction clutch associated with the engine for a motor vehicle.
[0015] A cet effet, l'invention propose un dispositif permettant une indexation relative des cannelures d'un arbre primaire d'une boîte de vitesses et d'un moyeu central d'un embrayage à friction couplé à un volant moteur de support d'une couronne de démarreur d'un moteur pour un véhicule, notamment automobile, pour l'engagement de l'arbre primaire cannelé dans le moyeu central cannelé lors d'une opération d'accostage de la boîte de vitesses au moteur, et qui est caractérisé en ce qu'il comprend un outil à poignée de manœuvre amoviblement monté au carter du moteur et dont l'extrémité opposée à la poignée de manœuvre est configurée pour venir en engrènement avec la couronne de démarreur pour déplacer concomitamment en rotation à l'aide de la poignée de manœuvre la couronne du démarreur et le moyeu central cannelé à une position angulaire d'indexation permettant l'engagement de l'arbre primaire cannelé dans le moyeu cannelé. [0016] De préférence, l'outil d'indexation comprend une tige solidaire de la poignée de manœuvre et pourvue de l'extrémité apte à venir en engrènement avec la couronne du démarreur et un pion pouvant s'engager amoviblement dans un trou lisse du carter du moteur et assemblé à la tige de manière à permettre un déplacement en translation de l'outil d'indexation relativement au pion engagé dans le trou lisse pour amener en engrènement l'extrémité de la tige avec la couronne de démarreur ainsi qu'un pivotement de l'outil d'indexation autour du pion lorsque l'extrémité de la tige est en engrènement avec la couronne de démarreur.

[0018] La tige s'étend en prolongement de la poignée de manœuvre et l'outil d'indexation, lorsqu'occupant sa position montée au carter du moteur, s'étend sensiblement dans un plan contenant la couronne de démarreur. Advantageously, the pin is mounted through a light extending along the rod of the indexing tool and the end of the rod is tooth-shaped capable of engaging between two teeth. successive stages of the starter ring. The rod extends in extension of the operating handle and the indexing tool, when occupying its position mounted to the motor housing, extends substantially in a plane containing the starter ring.
[0019] Avantageusement, le pion comprend deux parties cylindriques coaxiales assemblées l'une à l'autre par une vis, respectivement une première partie cylindrique engagée dans la lumière de la tige de l'outil d'indexation et une seconde partie cylindrique de plus grand diamètre pouvant s'engager dans le trou lisse du carter du moteur. Advantageously, the pin comprises two coaxial cylindrical parts assembled to each other by a screw, respectively a first cylindrical portion engaged in the light of the indexing tool shank and a second cylindrical portion of more large diameter that can engage in the smooth hole of the motor housing.
[0020] L'invention vise également un outil destiné à une indexation relative des cannelures d'un arbre primaire d'une boîte de vitesses et d'un moyeu central d'un embrayage couplé à un volant moteur de support d'une couronne de démarreur d'un moteur pour un véhicule, notamment automobile, pour l'engagement de l'arbre primaire cannelé dans le moyeu central cannelé lors d'une opération d'accostage de la boîte de vitesses au moteur, et qui est caractérisé en ce qu'il comprend une poignée de manœuvre, une tige de prolongement de la poignée de manœuvre pourvue d'une lumière s'étendant le long de la tige dont une extrémité est en forme de dent et un pion assemblé dans la lumière de la tige transversalement à celle-ci. The invention also relates to a tool for relative indexing splines of a primary shaft of a gearbox and a central hub of a clutch coupled to a flywheel supporting a crown of motor starter for a vehicle, in particular an automobile, for the engagement of the splined primary shaft in the splined central hub during an operation of contacting the gearbox with the engine, and which is characterized in that it comprises an operating handle, an extension rod of the operating handle provided with a lumen extending along the rod, one end of which is tooth-shaped and a peg assembled in the lumen of the rod transversely to it.

- les figures 5 et 6 représentent l'utilisation de l'outil d'indexation permettant d'indexer les cannelures de l'arbre primaire de la boîte de vitesses aux cannelures du moyeu central de l'embrayage à friction. [0024] En se reportant aux figures, la référence 1 désigne un moteur thermique pour un véhicule automobile et auquel est couplé un embrayage à friction 2. - Figures 5 and 6 show the use of the indexing tool for indexing the splines of the primary shaft of the gearbox to the splines of the central hub of the friction clutch. Referring to the figures, the reference 1 designates a heat engine for a motor vehicle and which is coupled to a friction clutch 2.
[0025] Le moteur thermique 1 comprend un carter 3 dans lequel est monté à rotation l'arbre vilebrequin 4 du moteur thermique 1 . [0026] Un volant moteur 5 est fixé à l'arbre vilebrequin 4 par des vis de fixation, non représentées. The heat engine 1 comprises a housing 3 in which is rotatably mounted the crankshaft 4 of the heat engine 1. A flywheel 5 is fixed to the crankshaft 4 by fixing screws, not shown.
[0027] Le volant moteur 5 comporte, solidaire de celui-ci, une couronne de démarreur extérieurement dentée 6. [0028] L'embrayage à friction 2 est destiné à assurer le passage du couple moteur provenant du vilebrequin 4 du moteur thermique 1 à l'arbre primaire 7 d'une boîte de vitesses 8 du véhicule automobile. The flywheel 5 comprises, integral with it, an externally toothed starter ring 6. The friction clutch 2 is intended to ensure the passage of the engine torque from the crankshaft 4 of the heat engine 1 to the primary shaft 7 of a gearbox 8 of the motor vehicle.
[0029] Comme cela est connu en soi, l'embrayage à friction 2 comprend, logé dans un couvercle d'embrayage 9 fixé au volant 5 par des vis de fixation non représentées, un diaphragme 10 et un plateau de pression 1 1 sur lequel agit le diaphragme 10 pour serrer deux garnitures de friction 12 sur une surface de friction du volant moteur 5 en position embrayée. As is known per se, the friction clutch 2 comprises housed in a clutch cover 9 attached to the flywheel 5 by unrepresented fastening screws, a diaphragm 10 and a pressure plate 1 1 on which The diaphragm 10 acts to clamp two friction linings 12 on a friction surface of the flywheel 5 in the engaged position.
[0030] Les deux garnitures de friction 12 sont solidaires d'un voile ou disque d'embrayage 13 dont le moyeu central 14 est intérieurement cannelé pour lui permettre d'être accouplé à la partie cannelée 15 de l'arbre primaire 7 de la boîte de vitesses 8 comme représenté en figure 1 . The two friction linings 12 are integral with a sail or clutch disc 13 whose central hub 14 is internally splined to allow it to be coupled to the fluted portion 15 of the primary shaft 7 of the box 8 as shown in FIG.
[0031 ] En position débrayée, un levier de commande, non représenté, repousse une butée 16 de manière que le diaphragme 10 relâche le plateau de pression 1 1 des garnitures de friction 12 et assure le débrayage. [0032] Ainsi, on peut considérer que le volant moteur 5, le mécanisme d'embrayage 10, 1 1 et le disque d'embrayage 13 à garnitures de friction 12 constituent un seul ensemble. In the disengaged position, a control lever, not shown, pushes a stop 16 so that the diaphragm 10 releases the pressure plate 1 1 of the friction lining 12 and ensures the disengagement. Thus, it can be considered that the flywheel 5, the clutch mechanism 10, 1 1 and the clutch plate 13 with friction linings 12 constitute a single assembly.
[0033] Lorsque l'arbre primaire 7 est engagé par sa partie cannelée 15 dans le moyeu central cannelé 14, l'extrémité libre 17 de l'arbre primaire 7 est montée folle dans un trou borgne 18 de l'arbre vilebrequin 4. [0034] Comme déjà expliqué précédemment, lors de la phase d'accostage du moteur thermique 1 à la boîte de vitesses 8 en usine terminale, la partie cannelée 15 de l'arbre primaire 7 de la boîte de vitesses doit normalement s'engager avec les cannelures 14a du moyeu central 14, mais il peut arriver qu'un tel engagement ne puisse s'effectuer. When the primary shaft 7 is engaged by its splined portion 15 in the central hub splined 14, the free end 17 of the primary shaft 7 is mounted idle in a blind hole 18 of the crankshaft 4. [ 0034] As already explained above, during the docking phase of the heat engine 1 to the gearbox 8 in the terminal plant, the splined portion 15 of the primary shaft 7 of the gearbox must normally engage with the splines 14a of the central hub 14, but it may happen that such a commitment can not be made.
[0035] L'invention propose un outil 20 qui permet d'agir sur la couronne de démarreur 6 du volant moteur 5 pour effectuer une rotation concomitante du volant moteur 5, du mécanisme d'embrayage 10, 1 1 occupant sa position embrayée d'application des garnitures de friction 12 en contact de friction sur la surface de friction du volant moteur 5 et du moyeu central 14 afin d'indexer les cannelures 14a de ce moyeu relativement à la partie cannelée 15 de l'arbre primaire 7 de la boîte de vitesses et permettre l'engagement de l'arbre primaire 7 dans le moyeu central 14 lors de l'opération d'accostage de la boîte de vitesses 8 au moteur thermique 1 . The invention provides a tool 20 which acts on the starter ring 6 of the flywheel 5 to perform a concomitant rotation of the flywheel 5, the clutch mechanism 10, 1 1 occupying its engaged position of applying the friction linings 12 in frictional contact with the friction surface of the flywheel 5 and the central hub 14 so as to index the splines 14a of this hub relative to the splined portion 15 of the primary shaft 7 of the gearbox and allow the engagement of the primary shaft 7 in the central hub 14 during the approaching operation of the gearbox 8 to the engine 1.
[0036] A cet effet, l'outil d'indexation 20 comprend une poignée de manœuvre 21 de forme générale cylindrique et une tige 22 solidaire d'une extrémité de la poignée de manœuvre 21 en prolongeant coaxialement cette dernière. [0037] La tige 22 de l'outil d'indexation 20 a son extrémité libre présentant la forme d'une dent 23 pouvant s'engager entre deux dents successives 6a de la couronne de démarreur 6 comme on le verra ultérieurement. For this purpose, the indexing tool 20 comprises a maneuvering handle 21 of generally cylindrical shape and a rod 22 integral with one end of the operating handle 21 coaxially extending the latter. The rod 22 of the indexing tool 20 has its free end having the shape of a tooth 23 engageable between two successive teeth 6a of the starter ring 6 as will be seen later.
[0038] La tige 22 de l'outil d'indexation 20 comporte une lumière 24 s'étendant le long de la tige 22 en étant située dans le plan médian longitudinal de la poignée 21 , de la tige 22 et de la dent 23. The rod 22 of the indexing tool 20 has a slot 24 extending along the rod 22 being located in the longitudinal median plane of the handle 21, the rod 22 and the tooth 23.
[0039] Comme représenté, la tige 22 est en forme de barreau plat. As shown, the rod 22 is in the form of a flat bar.
[0040] L'outil d'indexation 20 comprend en outre un pion 25 monté au travers de la lumière 24 transversalement à la tige 22 de manière à pouvoir se déplacer en translation le long de la lumière 24. [0041 ] De préférence, le pion 25 comprend deux parties généralement cylindriques de plus petit diamètre 26 engagées dans la lumière 24 et de plus grand diamètre 27 faisant saillie d'un côté de la tige plate 22 perpendiculairement à celle-ci. The indexing tool 20 further comprises a pin 25 mounted through the lumen 24 transversely to the rod 22 so as to be able to move in translation along the lumen 24. [0041] Preferably, the pin 25 comprises two generally cylindrical portions of smaller diameter 26 engaged in the lumen 24 and of larger diameter 27 protruding from one side of the flat rod 22 perpendicular thereto.
[0042] Les deux parties cylindriques 26 et 27 sont solidarisées coaxialement et en aboutement l'une à l'autre par une vis de fixation 28 dont la tige filetée 29 traverse la partie cylindrique de plus petit diamètre 26 et est ancrée dans un trou taraudé traversant 30 de la partie cylindrique de plus grand diamètre 27 du pion 25, la tête hexagonale 31 de la vis 28 étant en appui sur l'extrémité de la partie de plus petit diamètre 26 opposée à la partie de plus grand diamètre 27 et faisant saillie du côté de la tige 22 opposé à la partie 27. Comme le montre clairement la figure 4, la partie de plus petit diamètre 26 du pion 25 présente une largeur supérieure à l'épaisseur de la tige plate 22 de l'outil d'indexation 20 de manière que ses deux extrémités débordent de part et d'autre de la tige 22. [0043] L'extrémité de la partie de plus grand diamètre 27 du pion 25 comporte deux méplats diamétralement opposés 32 pouvant s'engager dans une fourche d'une clef plate pour permettre le serrage de la vis de fixation 28 dans la partie de plus grand diamètre 27 et de bloquer axialement cette dernière contre la partie de plus petit diamètre 26 du pion 25. De la sorte, la partie de plus petit diamètre est maintenue dans la lumière 24. The two cylindrical parts 26 and 27 are coaxially secured and abutted to one another by a fastening screw 28 whose threaded rod 29 passes through the cylindrical portion of smaller diameter 26 and is anchored in a threaded hole passing through the cylindrical portion of larger diameter 27 of the pin 25, the hexagonal head 31 of the screw 28 bearing on the end of the smaller diameter portion 26 opposite the larger diameter portion 27 and projecting the side of the rod 22 opposite the portion 27. As clearly shown in Figure 4, the smaller diameter portion 26 of the pin 25 has a width greater than the thickness of the flat rod 22 of the indexing tool 20 so that its two ends protrude on either side of the rod 22. The end of the larger diameter portion 27 of the pin 25 comprises two diametrically opposed flats 32 which can engage in a fork of a flat key to allow the tightening of the fastening screw 28 in the part of more large diameter 27 and axially lock the latter against the smaller diameter portion 26 of the pin 25. In this way, the smaller diameter portion is maintained in the slot 24.
[0044] La partie de plus grand diamètre 27 peut s'engager amoviblement dans l'un des trous lisses 33 du carter 3 du moteur thermique 1 , ces trous lisses permettant d'assurer la fixation du carter 8a de la boîte de vitesses 8 au carter 3 du moteur thermique. The larger diameter portion 27 can engage removably in one of the smooth holes 33 of the housing 3 of the heat engine 1, these smooth holes to ensure the fixing of the housing 8a of the gearbox 8 to housing 3 of the engine.
[0045] Le procédé d'indexation relative des cannelures 15 et 14a de l'arbre primaire 7 et du moyeu central 14 à l'aide de l'outil d'indexation 20 pour permettre l'engagement de l'arbre primaire cannelé 7 dans le moyeu central cannelé 14 lors de l'opération d'accostage de la boîte de vitesses 8 au moteur thermique 1 s'effectue comme suit. The relative indexing process of the splines 15 and 14a of the primary shaft 7 and the central hub 14 with the indexing tool 20 to allow the engagement of the splined primary shaft 7 in the splined central hub 14 during the approaching operation of the gearbox 8 to the heat engine 1 is carried out as follows.
[0046] La boîte de vitesses, qui est supportée par une grue d'atelier à l'aide d'élingues, est positionnée relativement au moteur thermique 1 posé sur une table du poste d'accostage, de manière à disposer l'arbre primaire 7 en regard et à proximité du moyeu central 14 à proximité de celui-ci. The gearbox, which is supported by a workshop crane with the aid of slings, is positioned relative to the engine 1 placed on a table of the berth, so as to have the primary shaft 7 next to and near the central hub 14 near it.
[0047] L'opérateur monte l'outil d'indexation 20 au carter 3 du moteur thermique 1 en engageant la partie de plus grand diamètre 27 du pion 25 dans le trou lisse correspondant 33 du carter 3. [0048] Ensuite, l'opérateur, à l'aide de la poignée de manœuvre 21 , effectue une translation de la tige 22 de l'outil 20 relativement au pion fixe 25 par l'intermédiaire de la lumière 24 coulissant sur la partie de plus petit diamètre 26 du pion 25 jusqu'à ce que l'extrémité en forme de dent 23 de la tige 22 s'engage entre deux dents successives 6a de la couronne de démarreur 6. [0049] L'opérateur peut alors agir sur la poignée 21 de l'outil d'indexation 20 pour faire office de levier de pivotement autour du pion fixe 25 et faire tourner concomitamment la couronne de démarreur 6, le volant moteur 5 et le moyeu central 14 du fait que l'embrayage à friction 2 occupe sa position embrayée pour amener le moyeu central 14 à une position d'indexation relativement à l'arbre primaire 7 à laquelle, normalement, les cannelures 15 de l'arbre primaire 7 peuvent s'engager avec les cannelures correspondantes 14a du moyeu central 14. [0050] Enfin, l'outil d'indexation 20 est retiré du carter 3 du moteur thermique 1 en désengageant le pion 25 du trou lisse correspondant 33 du carter 3 et l'opérateur effectue une tentative d'engagement de l'arbre primaire 7 dans le moyeu central 14 pour réaliser l'accostage de la boîte de vitesses 8 au moteur thermique 1 . [0051 ] Dans l'hypothèse où la tentative d'engagement de l'arbre primaire 7 dans le moyeu central 14 serait infructueuse, l'opérateur peut alors répéter à nouveau les étapes de montage de l'outil d'indexation 20 au carter 3 du moteur thermique 1 , de translater cet outil par rapport au pion fixe 25 pour engager l'extrémité en forme de dent 23 entre deux dents successives 10a de la couronne de démarreur 6 et agir sur la poignée 21 pour la faire pivoter autour du pion fixe 25 et faire tourner concomitamment la couronne de démarreur 6, le volant moteur 5 et le manchon central 14 à une nouvelle position d'indexation à laquelle l'arbre primaire 7 devrait pouvoir s'engager dans le moyeu central 14. The operator mounts the indexing tool 20 to the casing 3 of the heat engine 1 by engaging the larger diameter portion 27 of the pin 25 in the corresponding smooth hole 33 of the casing 3. [0048] Then, the The operator, by means of the operating handle 21, translates the rod 22 of the tool 20 relative to the fixed pin 25 via the slot 24 sliding on the smaller diameter portion 26 of the pin 25. until the tooth-shaped end 23 of the rod 22 engages between two successive teeth 6a of the starter ring 6. The operator can then act on the handle 21 of the tool indexing 20 to act as a lever for pivoting around the fixed pin 25 and simultaneously rotate the starter ring 6, the flywheel 5 and the central hub 14 because the friction clutch 2 is in its engaged position to bring the central hub 14 at an indexing position relative to the primary shaft 7 to which, normally, the splines 15 of the primary shaft 7 can engage with the corresponding splines 14a of the central hub 14. Finally, the indexing tool 20 is removed from the housing 3 of the heat engine 1 by disengaging the pin 25 of the corresponding smooth hole 33 of the housing 3 and the operator makes an attempt to engage the primary shaft 7 in the central hub 14 to achieve the docking of the gearbox 8 to the engine 1. In the event that the attempt to engage the primary shaft 7 in the central hub 14 would be unsuccessful, the operator can then repeat the steps of mounting the indexing tool 20 to the housing 3 of the heat engine 1, to translate this tool relative to the fixed pin 25 to engage the tooth-shaped end 23 between two successive teeth 10a of the starter ring 6 and act on the handle 21 to rotate it around the fixed pin 25 and simultaneously rotate the starter ring 6, the flywheel 5 and the central sleeve 14 to a new indexing position to which the input shaft 7 should be able to engage in the central hub 14.
[0052] Il est à noter qu'en position de montage de l'outil d'indexation 20 au carter 3 du moteur thermique 1 , la poignée 21 , la tige 22 et l'extrémité en forme de dent 23 de la tige 22 s'étendent sensiblement dans un plan contenant la couronne de démarreur 6 en faisant radialement saillie de cette dernière. It should be noted that in the mounting position of the indexing tool 20 to the housing 3 of the heat engine 1, the handle 21, the rod 22 and the tooth-shaped end 23 of the rod 22 s extend substantially in a plane containing the starter ring 6 radially projecting from the latter.
[0053] L'outil d'indexation 20 de l'invention est d'une structure extrêmement simple et la lumière de réglage 24 de cet outil permet d'ajuster la position de la dent d'extrémité de cet outil par rapport au pion 25 fixé au carter du moteur et d'adapter l'outil aux différents diamètres de couronnes de démarreur solidaires de volants moteur de moteurs thermiques. The indexing tool 20 of the invention is of an extremely simple structure and the adjustment light 24 of this tool makes it possible to adjust the position of the end tooth of this tool relative to the pin 25. attached to the motor housing and to adapt the tool to the different diameters of starter rings integral flywheel motor engines.
[0054] L'utilisation de l'outil d'indexation de l'invention pour assurer l'engagement de l'arbre primaire cannelé d'une boîte de vitesses dans le moyeu central cannelé d'un embrayage à friction procure un gain important de temps de montage et donc de productivité en usine terminale au poste d'accostage moteur-boîte de vitesses et diminue considérablement les risques d'endommagement des cannelures de l'arbre primaire, d'endommagement du joint d'étanchéité de transmission gauche et d'endommagement du moyeu central de l'embrayage à friction. The use of the indexing tool of the invention to ensure the engagement of the splined primary shaft of a gearbox in the central hub grooved friction clutch provides a significant gain of installation time and thus productivity in the final factory at the engine-gearbox berth and considerably reduces the risk of damage to the splines of the main shaft, damage to the left transmission seal and Damage to the center hub of the friction clutch.
