Abstract
Description
La présente invention est relative à des perfectionnements apportés aux démarreurs électriques pour moteurs thermiques et elle vise plus particulièrement les démarreurs du genre en question qui comportent deux moteurs électriques de commande. The present invention relates to improvements made to electric starters for internal combustion engines and it relates more particularly to starters of the type in question which comprise two electric control motors.
On connait, par exemple par le brevet américain 2 302 680, des démarreurs du genre en question dont l'un des moteurs sert à l'avancement du lanceur par rotation d'un écrou longitudinalement fixe coopérant avec un filetage externe d'une douille montée autour de l'arbre de l'induit du moteur principal. La puissance des deux moteurs s'ajoute pour transmettre un effort accru au pignon du lanceur. Un tel démarreur est complexe car le moteur auxiliaire actionne l'écrou par l'intermédiaire d'un renvoi d'angle denté dont la réalisation est onéreuse et le montage délicat. Un tel démarreur ne peut pas permettre l'utilisation d'un réducteur associé à l'arbre de l'induit du moteur principal, de telle sorte que ce dernier doit être largement dimensionné. We know, for example from US Patent 2,302,680, starters of the kind in question, one of the motors of which is used for advancing the launcher by rotation of a longitudinally fixed nut cooperating with an external thread of a mounted socket around the armature shaft of the main motor. The power of the two motors is added to transmit an increased force to the pinion of the starter. Such a starter is complex because the auxiliary motor actuates the nut by means of a toothed angle gear, the construction of which is expensive and the assembly delicate. Such a starter cannot allow the use of a reduction gear associated with the armature shaft of the main motor, so that the latter must be largely dimensioned.
Suivant l'invention, le premier moteur actionne un réducteur dont la roue de sortie comporte un moyeu à alésage cannelé de manière hélicoldale qui coopère avec la périphérie de forme complémentaire de la queue tubulaire du lanceur, l'arbre le long duquel coulisse ce dernier comprenant une portée à nervures droites qui s'engage dans des rainures axiales ménagées dans l'alésage de la queue tubulaire précitée, tandis que l'arbre du lanceur est solidaire de la roue de sortie d'un réducteur actionné par le second moteur. According to the invention, the first motor actuates a reduction gear whose output wheel comprises a hub with helically grooved bore which cooperates with the periphery of complementary shape of the tubular tail of the launcher, the shaft along which slides the latter comprising a bearing with straight ribs which engages in axial grooves formed in the bore of the aforementioned tubular tail, while the starter shaft is integral with the output wheel of a reduction gear actuated by the second motor.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une coupe transversale d'un démarreur électrique comportant application des perfectionnements suivant l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a cross section of an electric starter comprising application of improvements according to the invention.
Fig. 2 illustre un dispositif de freinage de la roue de sortie du réducteur actionnée par le second moteur. Fig. 2 illustrates a device for braking the output wheel of the reduction gear actuated by the second motor.
Fig. 3 en est une coupe suivant III-III (Fig.- 2). Fig. 3 is a section on III-III (Fig. 2).
On a illustré en fig. 1 un démarreur électrique pour moteur thermique comportant un carter 1 renfermant les divers mécanismes d'actionnement du lanceur 2 du démarreur en question, ce lanceur étant pourvu à la manière usuelle d'un pignon 3 destiné à venir en prise avec une couronne 4 associée au moteur thermique. Le lanceur 2 comporte, comme à l'accoutumée, une roue libre 5 à cage extérieure 5a solidaire d'une queue tubulaire 6 dont l'alésage interne comporte des rainures droites 7. ladite queue peut donc coulisser par rapport à une portée 8 pourvue de rainures complémentaires à celles 7 et qui fait partie d'un arbre 9 solidaire de la roue de sortie 10 d'un réducteur 11 entraîné par le second moteur 12 du réducteur suivant l'invention.L'arbre 9 comporte une partie 9a à diamètre réduit le long de laquelle coulisse le prolongement de la piste intérieure 5b de la roue libre 5, ce prolongement constituant support pour le coulissement du lanceur 2. Illustrated in fig. 1 an electric starter for an internal combustion engine comprising a casing 1 containing the various mechanisms for actuating the starter 2 of the starter in question, this starter being provided in the usual manner with a pinion 3 intended to engage with a crown 4 associated with the thermal motor. The launcher 2 comprises, as usual, a freewheel 5 with an external cage 5a secured to a tubular tail 6 whose internal bore has straight grooves 7. said tail can therefore slide relative to a bearing surface 8 provided with grooves complementary to those 7 and which is part of a shaft 9 integral with the output wheel 10 of a reduction gear 11 driven by the second motor 12 of the reduction gear according to the invention. The shaft 9 comprises a part 9a with reduced diameter along which slides the extension of the inner track 5b of the freewheel 5, this extension constituting support for the sliding of the launcher 2.
La périphérie de la douille 6 est pourvue de rainures hélicoidales 13 qui sont en prise avec des nervures complémentaires 14a ménagées dans l'alésage d'une roue dentée 14, comportant un manchon tubulaire 14b à plus grand diamètre dont la périphérie coopère avec un palier 15 solidaire du carter 1 par l'intermédiaire d'un coussinet 16. The periphery of the sleeve 6 is provided with helical grooves 13 which are engaged with complementary ribs 14a formed in the bore of a toothed wheel 14, comprising a tubular sleeve 14b with a larger diameter whose periphery cooperates with a bearing 15 secured to housing 1 by means of a bearing 16.
La denture périphérique 14c de la roue 14 est en prise avec le pignon de sortie 17 du premier moteur 18 par l'intermédiaire d'un pignon double 19. The peripheral toothing 14c of the wheel 14 is engaged with the output pinion 17 of the first motor 18 by means of a double pinion 19.
On observe que le pignon double 19 est monté libre sur un arbre 20 autour duquel tourillonne un second pignon double 21 faisant partie du réducteur 11. It can be seen that the double pinion 19 is mounted free on a shaft 20 around which a second double pinion 21 which forms part of the reducer 11 journals.
Le fonctionnement est le suivant
Le moteur 18 est d'abord mis sous tension, ce qui provoque la rotation de la roue 14. Comme la douille 6 est immobilisée en rotation par les frottements, la coopération des rainures hélicoldales 13 avec celles complémentaires 14a de ladite roue provoque le déplacement longitudinal du lanceur 2 en direction de la gauché, de sorte que son pignon 3 vient, à la manière habituelle, en prise avec la grande couronne 4 du moteur thermique. A ce moment, le moteur 12 est mis sous tension pour faire tourner l'arbre 9 qui, par l'intermédiaire des rainures droites de sa portée 8, entrasse la rotation de la douille 6 et par conséquent celle du pignon 3 qui commande la grande couronne 4 et le démarrage du moteur thermique.On note qu'alors les couples développés par les-deux moteurs s'appliquent sur le pignon 3.The operation is as follows
The motor 18 is first put under tension, which causes the rotation of the wheel 14. As the sleeve 6 is immobilized in rotation by friction, the cooperation of the helical grooves 13 with those complementary 14a of said wheel causes the longitudinal displacement of the launcher 2 in the direction of the left, so that its pinion 3 comes, in the usual way, in engagement with the large crown 4 of the heat engine. At this time, the motor 12 is energized to rotate the shaft 9 which, by means of the straight grooves of its bearing surface 8, overlaps the rotation of the sleeve 6 and consequently that of the pinion 3 which controls the large crown 4 and starting the heat engine. Note that the torques developed by the two motors then apply to the pinion 3.
I1 est évident que l'avancement du lanceur ne peut s'effectuer que si l'arbre 9 est immobile en rotation. Comme indiqué plus haut, les divers frottements peuvent permettre cette immobilisation angulaire, mais on peut associer à la roue 10 un dispositif d'immobilisation 22 illustré en fig. 2 et 3. It is obvious that the advancement of the launcher can only take place if the shaft 9 is stationary in rotation. As indicated above, the various frictions can allow this angular immobilization, but it is possible to associate with the wheel 10 an immobilizing device 22 illustrated in FIG. 2 and 3.
Le dispositif 22 s'adapte au pignon 10 engrenant avec la roue 21 du réducteur 11. L'un des flancs du pignon 10 porte deux axes diamétrale, ment opposés 24 autour desquels sont montés à basculement deux sabots 25 propres à coopérer avec une jante fixe 26, par exemple solidaire du carter I grâce à la présence de deux ressorts de traction 27. Les sabots 25 sont dissvmétriques, ctest-a-dire que la distance séparant leur partie active ou patin 25a qui coopère avec la jante 26 est largement inférieure à celle qui sépare Itaxe en question de la partie carrière 25b desdits sabots.De cette marnière, lorsque la roue 10 tourne entraînée par la roue 1, la force centrifuge fait basculer les sabots, de telle sorte que leur patins 2fa quittent la jante 26. La course vers l'extérieur des sabots est limitée par des pions 28 engagés dans des encoches de ces sabots. Ainsi, pour revenir au fonctionnement ci-dessus, lorsque la roue l tourne, elle fait obligatoirement avancer le lanceur 2 du fait que la portée 8-de lrarbre 9 est immobilisée en rotation par le dispositif 22. The device 22 adapts to the pinion 10 meshing with the wheel 21 of the reduction gear 11. One of the sides of the pinion 10 carries two diametrical axes, opposite opposite 24 around which two shoes 25 are mounted to tilt capable of cooperating with a fixed rim 26, for example secured to the casing I by virtue of the presence of two tension springs 27. The shoes 25 are dissymmetrical, that is to say that the distance separating their active part or shoe 25a which cooperates with the rim 26 is much less than that which separates Itaxe in question from the quarry part 25b of the said shoes. From this hinge, when the wheel 10 rotates driven by the wheel 1, the centrifugal force causes the shoes to tilt, so that their pads 2fa leave the rim 26. The outward travel of the hooves is limited by pins 28 engaged in the notches of these hooves. Thus, to return to the above operation, when the wheel 1 rotates, it obligatorily causes the launcher 2 to advance because the range 8 of the shaft 9 is immobilized in rotation by the device 22.
Une fois que le moteur thermique a démarré a la maniere usuelle, la roue libre 5 désolidarise le pignon 3 de l'arbre 9 et un ressort de compression 29 disposé entre une portée 14d de la roue 14 et une butée 30 solidaire de la douille 6 provoque le retour a sa position initiale du lanceur lors de l'arrêt des moteurs 18 et 12. La butée 30 constitue une limite d'avancement du lanceur du fait qu'elle vient buter sur l'arête libre du manchon 14b de la roue 14. Once the heat engine has started in the usual way, the freewheel 5 separates the pinion 3 from the shaft 9 and a compression spring 29 disposed between a bearing 14d of the wheel 14 and a stop 30 integral with the sleeve 6 causes the launcher to return to its initial position when the engines 18 and 12 stop. The stop 30 constitutes a limit on the advance of the launcher because it abuts on the free edge of the sleeve 14b of the wheel 14 .
Il doit d'ailleurs tre entendu que la description qui précède n'a été-donnée qu' titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
