- the coupling piece is integral with the driver so that the surface 37 belongs to the driver and the surface 39 to the pinion.
- a first disadvantage of such a solution is that, depending on the geometrical dispersion of the starter parts, the actuating force exerted by the lever 25 on the driver 33 during the excitation of the contactor 18 would be very high, causing therefore, an increase in the mechanical pressure of the liner 39 on the first friction surface 37. This high contact pressure in the friction clutch would cause premature wear of the friction clutch, with formation in more than one embodiment. significant residual drag torque that could degrade the freewheel function of the launcher 26.

- the presence of the priming spring causes an axial or radial action to obtain a drag torque friction between the driver and the pinion, while the friction surfaces are spaced apart at rest, the rest position of the friction clutch corresponding to the rest position of the launcher.
- This drag torque is sufficient to precisely initiate self-locking of the launcher during the training phase, but remains relatively low so as not to significantly decrease the speed differential in freewheeling phase and not to obliterate the action of the spring teeth against teeth.
- the priming spring makes it possible to reduce the contact pressure between the friction surfaces and to detach the friction surfaces relative to one another because it is arranged in the launcher so as to move the drive away from the pinion, which reduces wear and improve freewheel operation.
- the priming spring has a filter function because it also dampens vibrations and especially shocks when the friction surfaces come into contact with each other. The matting phenomena of the friction surfaces are therefore reduced.
- the friction surfaces of the free wheel are thus provided in all phases so that the life of the starter is increased.
- the friction clutch of the freewheel is of frustoconical shape
- greater latitude is provided for modifying the angle of the friction surfaces because the priming spring is arranged in the launcher so as to move the coach away from the pinion.
- the angle of the friction surfaces can be increased or decreased.
- the friction clutch is semi-spherical shape also has greater latitude to change the radius of curvature.

- the size of the abutment 47 is defined in such a way that it can cooperate with the rear face of the lining 39 (see FIG. Figures 5 to 7 ).
- the blocking of the freewheeling caster 34 by friction is obtained by the combined action of the splines of the driver 33, driven by the electric motor via the teeth of the output shaft, and the cone friction after engagement of the two friction surfaces 37, 40.
- the electric motor 11 drives the pinion 32 and the ring gear for starting the internal combustion engine.
- the clutch is released in the freewheeling phase when the combustion engine drives the pinion 32 at a speed of rotation greater than that of the driver 33.
- the driver 33 has an annular groove 133 for receiving the fork-shaped lower portion of the lever 25 of the figure 1 .
- the invention proposes to initiate the internal self-locking of the freewheel 34 in the driving phase and to separate the friction surfaces 37,40 in freewheeling phase.
- the initiation of the self-locking is provided by an elastic device 51 internal to the free wheel 34, shaped according to a friction clutch, and intended to generate a low intensity drag force and to release the friction surfaces in the wheel phase free.
- this ignition device 51 generates a frictional drag torque between the driver 33 and the pinion 32, said torque being sufficient to initiate the self-locking of the launcher 26 in training phase, but relatively low not to significantly reduce the speed differential in the freewheel phase.
- the initiation of the self-locking of the friction clutch is provided by an elastic device 51 integrated in the launcher, with formation of a reaction between one of the driver elements 33-pinion 32 and the piece coupling 45 secured to the other of the 32-coach 33 gear elements.
- the reaction is of the axial type in the Figures 5 and 6 , and radial in the Figures 7 and 8 .

- the rear face of the lining 39 of the friction clutch is held against the stop 47 of the skirt 48, to generate a residual torque by friction between the coupling piece 45 and the coach 33.
- the presence of this spring R1 initiation causes a friction drag torque between the driver 33 and the pinion 32, said torque being sufficient to initiate self-locking of the launcher 26 in training phase, but relatively low so as not to significantly decrease the differential speed in freewheeling phase.
- This freewheeling phase is carried out according to a first step in which the friction surfaces are in contact with reduction of the contact pressure and a second step in which the friction surfaces are detached from one another under the action of the priming spring.
- the spring R1 is replaced by a coil spring R2 compression wedged between the front face 50 of the driver 33 and a shoulder of the bottom 46.
- the effect of this spring R2 is identical to that of the figure 5 , and this results in a plating force of the lining 39 against the abutment 47 of the skirt 48 with separation of the two friction surfaces 37, 40.
- the elastic device 51 comprises a spring R3 radial action, formed by an annular and corrugated elastic blade.
- the blade is interposed between a cylindrical extension 52 of the skirt 48, and the peripheral surface of the lining 39.
- the friction surfaces 37, 40 remain spaced in the rest position, and the permanent friction effect of the spring R3 against the workpiece coupling 45 and the lining 39, allows the clutch to self-priming following the formation of a resistant torque between the pinion 32 and the coach 33. This effort depends on the applications and is chosen not to disturb unduly the movement of the coach relative to the pinion.

Lorsque le contact mobile 27 vient en engagement avec les contacts fixes des bornes 19, 20 du contacteur 18, le moteur électrique 11 est alimenté électriquement via les bornes 19, 20, en sorte que l'arbre 14 tourne, et entraîne l'arbre de sortie 28, lequel est monté dans un palier 29 avant du support 16. L'extrémité avant de l'arbre 14, à l'opposé du collecteur 17, est configurée pour former un pignon solaire appartenant à un train épicycloïdal constituant un réducteur de vitesses 30 à engrenages, lequel est interposé entre l'arbre de sortie 28 et l'arbre 14 aligné du moteur électrique 11.

Le levier de commande 25, ici en forme de fourchette, est accouplé par sa partie supérieure au noyau mobile 23 via la tige 43 et le ressort 41, et comporte dans sa partie intermédiaire un axe de pivotement 31 pour son montage pivotant dans le démarreur.
La partie inférieure du levier 25, en forme de fourche, est montée dans une gorge annulaire 133 de l'entraîneur 33 et comporte des doigts ou patins profilés pour action sur les flancs de la gorge de l'entraîneur
L'axe 31 comporte ici deux tronçons s'étendant depuis des faces opposées du corps du levier 25, ici en matière plastique, en étant avantageusement venu de moulage avec le levier 25.
Ces tronçons sont montés de manière pivotante par exemple dans un palier en deux parties comportant une première partie reliée au support 16 en étant avantageusement venu de moulage avec celui-ci et une deuxième partie formée en vis-à-vis formant une cale entre l'actionneur 18, plus précisément la cuve de celui-ci, et la culasse 15 comme d écrit dans le document

L'entraîneur 33 est doté intérieurement de cannelures hélicoïdales en prise de manière complémentaire avec des dentures 36 hélicoïdales externes portées par l'arbre de sortie 28. Le lanceur 26 est ainsi animé d'un mouvement hélicoïdal lorsqu'il est déplacé par le levier 25 en direction d'une butée 35 fixe solidaire de l'arbre 28 pour venir en position avant d'engrènement, par l'intermédiaire de son pignon 32, en prise avec la couronne dentée de démarrage 300 du moteur à combustion du véhicule automobile.The

La surface de friction 37 appartient à la périphérie interne d'une jupe de la pièce d'attelage solidaire ici du pignon 26. En variante la garniture 37 est rapportée. L'entraîneur 33 est équipé à sa périphérie interne de cannelures 38 hélicoïdales d'entraînement en prise avec les dentures 36 complémentaires ménagées à la périphérie externe de l'arbre de sortie 28. L'entraîneur 33 est équipé également extérieurement d'une gorge de réception 133 de la fourche du levier de commande 25, et à l'avant d'une garniture 39 de friction ou de frottement de forme convexe, ici de forme tronconique. Cette garniture 39 est à base de matière plastique thermodurcissable ou thermoplastique, avantageusement chargée, pour obtenir le coefficient de frottement souhaité avec des usures faibles. La garniture 39 est ancrée dans un logement annulaire de l'entraîneur 33, et comporte à sa périphérie une deuxième surface de friction 40 convexe coopérant de manière complémentaire et coaxiale avec la première surface de friction 37 pour former un embrayage à friction tronconique constituant une liaison mécanique à roue libre, ici débrayable, entre le pignon 32 et l'entraîneur 33. En variante les surfaces de friction sont conformées pour former un embrayage à friction semi sphérique.
Un capot (non référencé) est serti sur une saillie de la pièce d'attelage et intervient à jeu axial entre la garniture 39 et la pièce d'attelage.

On remarque que lors de l'attraction du noyau mobile 23 contre le noyau fixe 24 du contacteur 18, le jeu d1 entre la butée 35 fixe et le pignon 32 en position avant d'engrènement avec la couronne dentée du volant du moteur à combustion, peut être soit positif (

Pour être sûr d'obtenir l'effet d'autoblocage du lanceur 26, il suffirait à priori de dimensionner le démarreur pour que le jeu d1 en phase d'entraînement du pignon 32 contre la butée 35, soit toujours négatif. Un premier inconvénient d'une telle solution est que, en fonction de la dispersion géométrique des pièces du démarreur, la force d'actionnement exercée par le levier 25 sur l'entraîneur 33 lors de l'excitation du contacteur 18 serait très élevée, provoquant de ce fait une augmentation de la pression mécanique de la garniture 39 sur la première surface de friction 37. Cette pression de contact importante dans l'embrayage à friction provoquerait une usure prématurée de l'embrayage à friction, avec formation en plus d'un important couple résiduel de traînée qui risquerait de dégrader la fonction roue libre du lanceur 26. Un deuxième inconvénient de cette solution à jeu négatif, est le choc mécanique que doit encaisser la butée 35 à chaque accostage du pignon 32 dans la phase d'entraînement.To be sure to obtain the self-locking effect of the
Dans La
En fonction de la dispersion géométrique ou de l'usure des pièces du lanceur, un positionnement imprécis de la rondelle élastique ou du ressort à l'intérieur du de la roue libre peut provoquer une variation de la pression de contact des surfaces de frottement, pouvant affecter la fonction d'autoamorçage de l'embrayage à friction ou la fonction de roue libre du lanceur.Depending on the geometrical dispersion or wear of the launcher parts, inaccurate positioning of the spring washer or spring inside the freewheel may cause a variation of the contact pressure of the friction surfaces, which may assign the self-priming function of the friction clutch or the freewheel function of the launcher.
L'objet de l'invention consiste à réaliser un démarreur équipé d'un lanceur à roue libre par friction qui remédie aux inconvénients précités, et permet d'amorcer de façon fiable l'autoblocage interne du lanceur en phase d'entraînement.The object of the invention is to provide a starter equipped with a freewheeling launcher that overcomes the aforementioned drawbacks, and reliably initiates internal self-locking of the launcher in training phase.
Un autre objet de l'invention est d'améliorer le fonctionnement en phase roue libre du lanceur.Another object of the invention is to improve the freewheeling operation of the launcher.
Un autre objet de l'invention est d'augmenter la durée de vie du démarreur.Another object of the invention is to increase the life of the starter.
Le démarreur selon l'invention du type dans lequel la pièce d'attelage est solidaire de l'un des éléments pignon- entraîneur est caractérisé en ce que le dispositif élastique comporte au moins un ressort d'amorçage intégré dans le lanceur entre la pièce d'attelage et l'autre des éléments entraîneur-pignon, dit second élément, de manière à écarter les deux surfaces de friction l'une de l'autre en position de repos du lanceur, tout en créant un couple résistant par frottement pour amorcer ledit autoblocage de la roue libre.The starter according to the invention of the type in which the coupling piece is integral with one of the pinion-drive elements is characterized in that the elastic device comprises at least one priming spring integrated in the launcher between the piece of coupling and the other of the gear-pinion elements, said second element, so as to move the two friction surfaces away from each other in the rest position of the launcher, while creating a friction-resistant torque to initiate said self-locking of the freewheel.
La présence du ressort d'amorçage engendre une action axiale ou radiale pour obtenir un couple de traînée par frottement entre l'entraîneur et le pignon, alors que les surfaces de friction sont écartées au repos, la position de repos de l'embrayage à friction correspondant à la position de repos du lanceur. Ce couple de traînée est suffisant pour amorcer avec précision l'autoblocage du lanceur en phase d'entraînement, mais reste relativement faible pour ne pas diminuer de façon importante le différentiel de vitesse en phase de roue libre et pour ne pas oblitérer l'action du ressort dents contre dents.The presence of the priming spring causes an axial or radial action to obtain a drag torque friction between the driver and the pinion, while the friction surfaces are spaced apart at rest, the rest position of the friction clutch corresponding to the rest position of the launcher. This drag torque is sufficient to precisely initiate self-locking of the launcher during the training phase, but remains relatively low so as not to significantly decrease the speed differential in freewheeling phase and not to obliterate the action of the spring teeth against teeth.
Le ressort d'amorçage permet en phase roue libre de diminuer la pression de contact entre les surfaces de friction et de décoller les surfaces de friction l'une par rapport à l'autre du fait qu'il est agencé dans le lanceur de manière à écarter l'entraîneur par rapport au pignon, ce qui permet de réduire les usures et d'améliorer le fonctionnement en phase roue libre.In the free-wheeling phase, the priming spring makes it possible to reduce the contact pressure between the friction surfaces and to detach the friction surfaces relative to one another because it is arranged in the launcher so as to move the drive away from the pinion, which reduces wear and improve freewheel operation.
Le ressort d'amorçage à une fonction de filtre car il permet également d'amortir les vibrations et notamment les chocs lorsque les surfaces de friction viennent en contact l'une avec l'autre. Les phénomènes de matage des surfaces de friction sont donc réduits.The priming spring has a filter function because it also dampens vibrations and especially shocks when the friction surfaces come into contact with each other. The matting phenomena of the friction surfaces are therefore reduced.
Les surfaces de friction de la roue libre sont ainsi ménagées dans toutes les phases en sorte que la durée de vie du démarreur est augmentée.The friction surfaces of the free wheel are thus provided in all phases so that the life of the starter is increased.
En outre dans le cas ou l'embrayage à friction de la roue libre est de forme tronconique, on bénéficie d'une plus grande latitude pour modifier l'angle des surfaces de friction du fait que le ressort d'amorçage est agencé dans le lanceur de manière à écarter l'entraîneur par rapport au pignon.
On peut donc par exemple augmenter ou diminuer l'angle des surfaces de friction.
Lorsque l'embrayage à friction est de forme semi-sphérique on bénéficie également d'une plus grande latitude pour modifier le rayon de courbure.In addition, in the case where the friction clutch of the freewheel is of frustoconical shape, greater latitude is provided for modifying the angle of the friction surfaces because the priming spring is arranged in the launcher so as to move the coach away from the pinion.
For example, the angle of the friction surfaces can be increased or decreased.
When the friction clutch is semi-spherical shape also has greater latitude to change the radius of curvature.
La raideur du ressort d'amorçage peut être déterminée avec moins de précision du fait que ce ressort à une action qui temps à écarter l'entraîneur par rapport au pignon et à libérer les surfaces de friction.The stiffness of the priming spring can be determined with less precision as this spring has an action that time to move the driver away from the pinion and release the friction surfaces.
D'autres caractéristiques peuvent être utilisées isolément ou en combinaison pour amorcer avec précision l'autoblocage du lanceur et débloquer les surfaces de friction en phase roue libre.
