"Dispositif pour l'accouplement d'une dynamo-démarreur et d'un moteur à combustion".
La présente invention se rapporte au montage d'une dynamo-démarreur à l'avant d'un moteur à combus- tion et elle a pour objet .un dispositif particulier pour l'accouplement des arbres de ces appareils .
Suivant cette invention, on dispose sur l'ex- trémité avant du vilebrequin du moteur une poulie à friction d'un genre déjà connu mais dont le moyeu est prolongé au-delà du vilebrequin et agencé pour être accouplé avec l'arbre de la dynamo-démarreur par l'in- termédiaire d'organes-élastiques.
<Desc/Clms Page number 2>
Grâce à cette combinaison très simple et d'encombrement extrêmement réduit, l'un des arbres peut tourner d'un angle quelconque par rapport à l'autre quand la différence entre les couples moteur et résistant dé- passe une valeur déterminée, de sorte que les effets des variations brusques de régime sont amortis par la friction autant qu'il est désirable pour éviter les détériorations et les ruptures d'organes, et la liaison entre les deux arbres conserve cependant à tout instant une élasticité constante qui s'oppose à la transmission des trépidations.
Le dessin ciannexé à titre d'exemple représen- te en élévation la partie avant d'un moteur et la dynamo-démarreur dont elle est munie, avec arrachement montrant en coupe le dispositif d'accouplement suivant l'invention.
1 désigne l'arbre vilebrequin, 2 l'arbre d'induit. Sur l'extrémité de l'arbre 1 est claveté un manchon 3 portant un disque de friction serré élasti- quement entre les deux joues 4 et 5 d'une poulie de fric- tion qui peut servir à la commande d'un ventilateur 6 ou à un autre usage.
Le serrage est obtenu par l'action de res- sorts 7 montés sur des goujons 8 et prenant appui contre des écrous 9 qui permettent de régler leur tension. La joue 4 de la poulie est prolongée vers l'avant par un moyeu 10 dans lequel sont ménagées des'échancrures 11.
@
L'extrémité arrière de l'arbre d'induit est engagée librement à l'intérieur du moyeu 10 et présente une échancrure dans laquelle sont encastrées des lames flexibles et élastiques 12, dont les extrémités se logent
<Desc/Clms Page number 3>
dans les échancrures 11.
Dans le cas ou une variation brusque de régime vient à se produire, un glissement a lieu entre le disque 3 et les joues 4, 5, jusqu'à ce que l'effort anormal disparaisse, ce qui permet à l'un des arbres de ne suivre les variations de vitesse de l'autre qu'avec un certain retard et une accélération positive ou négative relativement petite* En outre, les lames 12 reliant 1'arbre 2 à la poulie à friction assurent constamment une élasticité de transmission qui évite toute répercussion nuisible des trépidations du moteur sur le démarreur:
Il doit être entendu qu'on pourra sans s'écarter de cette invention remplacer les lames 12 par tous autres organes élastiques convenables.
D'autre part, la poulie à friction pourrait être montée sur l'arbre d'induit et l'accouplement élastique pourrait être intercalé entre la poulie et le vilebrequin.

"Device for coupling a dynamo-starter and a combustion engine".
The present invention relates to the mounting of a starter-dynamo at the front of a combustion engine and its object is a particular device for coupling the shafts of these devices.
According to this invention, there is placed on the front end of the crankshaft of the engine a friction pulley of a type already known, but the hub of which is extended beyond the crankshaft and arranged to be coupled with the shaft of the dynamo. -starter via elastic-members.
<Desc / Clms Page number 2>
Thanks to this very simple combination and extremely small size, one of the shafts can turn at any angle with respect to the other when the difference between the motor and resistance torques exceeds a determined value, so the effects of sudden variations in speed are damped by the friction as much as is desirable to avoid damage and breakage of components, and the connection between the two shafts however retains at all times a constant elasticity which opposes the transmission of trepidations.
The accompanying drawing by way of example shows in elevation the front part of an engine and the dynamo-starter with which it is provided, with cutaway showing in section the coupling device according to the invention.
1 designates the crankshaft shaft, 2 the armature shaft. On the end of the shaft 1 is keyed a sleeve 3 carrying a friction disc clamped elastically between the two cheeks 4 and 5 of a friction pulley which can be used to control a fan 6 or for another use.
Tightening is obtained by the action of springs 7 mounted on studs 8 and bearing against nuts 9 which allow their tension to be adjusted. The cheek 4 of the pulley is extended towards the front by a hub 10 in which des'écollures 11 are formed.
@
The rear end of the armature shaft is freely engaged inside the hub 10 and has a notch in which are embedded flexible and resilient blades 12, the ends of which are housed
<Desc / Clms Page number 3>
in the cutouts 11.
In the event that a sudden change in speed occurs, a slip takes place between the disc 3 and the cheeks 4, 5, until the abnormal force disappears, which allows one of the shafts to only follow the speed variations of the other with a certain delay and a relatively small positive or negative acceleration * In addition, the blades 12 connecting the shaft 2 to the friction pulley constantly ensure a transmission elasticity which avoids any harmful repercussions of the engine shaking on the starter:
It should be understood that, without departing from this invention, the blades 12 can be replaced by any other suitable elastic members.
On the other hand, the friction pulley could be mounted on the armature shaft and the elastic coupling could be interposed between the pulley and the crankshaft.
