DISPOSITIF D'ACCOUPLEMENT MECAHIQUE
PROGRESSIF UTILISANT LA FORCE CENTRIFUGE
La présenie inveution concerne un couplour mécanique progressif, de la roue libre à la prise directe, caractérisé par l'absence d friction et de liquide. Il ne chauffe pas, ne s'use pas et décroche on cas de surcharge, avec résnclanchement automatique.MECHANICAL COUPLING DEVICE
PROGRESSIVE USING CENTRIFUGAL FORCE
The present investment concerns a progressive mechanical coupling, from the freewheel to the direct drive, characterized by the absence of friction and of liquid. It does not heat, does not wear out and goes off in the event of an overload, with automatic reconnection.
Il est insensible à la température. It is insensitive to temperature.
Il n'y a pas de perte de puissance en prise directe. There is no loss of power in direct drive.
Il est très s8imble de conception (trois pièces dans le modèle élémentaire). It is very s8imble in design (three pieces in the elementary model).
L'arbre menant A (fig 1) entraine le bras G sur lequel est monté un axe molille C. The driving shaft A (fig 1) drives the arm G on which is mounted a molle axis C.
Sur cet axe est claveté d'un côté une masse excentrique F et de l'autre côté un pignon D qui roule sur (ou dans : fig F6 un pignon E solidaire de l'arbre mené B. On this axis is keyed on one side an eccentric mass F and on the other side a pinion D which rolls on (or in: fig F6 a pinion E secured to the driven shaft B.
Quand la vitesse augmente, la force centrifuge pousse la masselotte F.vers l'extérieur et tente de lty maintenir, freinant par là- même le pignon D et finissant par l'immobiliser par rapport à l'arbre A. When the speed increases, the centrifugal force pushes the flyweight F. outwards and tries to maintain it, thereby braking the pinion D and finally immobilizing it in relation to the shaft A.
Ceci entraîne alors l'arbre B à la même vitesse que l'arbre A, le tout formant bloc. This then drives the shaft B at the same speed as the shaft A, the whole forming a block.
Les masselottes réagissent à deux forces centrifuges différentes, l'une autour de l'axe C, l'autre autour de l'axe A, qui finit par l'emporter. The flyweights react to two different centrifugal forces, one around the C axis, the other around the A axis, which eventually prevails.
Les masselottes et les pignons sont calculés en fonction de la demande
En cas de surcharge ou de ralentissement trop prononcé, il y a déclenchement automatique.Weights and pinions are calculated according to demand
In the event of too pronounced overloading or slowing down, automatic triggering occurs.
Selon une variante (fig 2) oh peut désolidariser la masse F de l'axe C par un frein ou embrayage 11, commandé ou automatique. Il n'y a presque plu de résistance et plus d'entrainement, à la demande. According to a variant (fig 2) oh can separate the mass F from the axis C by a brake or clutch 11, controlled or automatic. There was almost no resistance and no more training, on demand.
Variante 2. : L'excentricité de la masse F peut être modulée par des moyens mécaniques, hydraliques ou électromagnétiques, qui permettent, à faible vitesse, un entrainement presque nul. Le plus simule est nn ressort de retenue (même figure). Variant 2.: The eccentricity of the mass F can be modulated by mechanical, hydraulic or electromagnetic means, which allow, at low speed, almost zero training. The most simulated is a retaining spring (same figure).
Variante 3 : La masse F pout être montée sur une-bielle (ou câme) eri bot de 7..'arbre 5. Elle ne tourne plus autour de cet axe et elle est continuellement rejetée vers l'extérieur (on peut prévoir uil guide). Il y a modification du rapport des forces ce@trifuges. Variant 3: The mass F can be mounted on a connecting rod (or cam) eri bot of 7 .. 'shaft 5. It no longer rotates around this axis and it is continually rejected towards the outside (we can provide a guide ). There is a change in the balance of forces ce @ trifuges.
Variante 4 : Dans le sens inverse, le système deviens un dijoncteur mécanique ou le rkenclanchement n'est pas automatique (parfois utile). Variant 4: In the opposite direction, the system becomes a mechanical circuit breaker or the closing is not automatic (sometimes useful).
Variante 5 : Dans le cas 011 la masse F est montre sur une bielle, un ressort (M peut également freiner cette bielle, modifiant ainsi l'entrainement à faible vitesse et nermettant une certaine réversibilité (fig. 3 bis). Variant 5: In case 011 the mass F is shown on a connecting rod, a spring (M can also brake this connecting rod, thus modifying the drive at low speed and allowing a certain reversibility (fig. 3 bis).
Variante 6 : (fig 4) Il est possible que l'arbre A entraine toujours l'arbre B, même à faible vitesse et avec démultiplication, sans pont mort possible. Dans ce cas l'arbre A, par l'axe C, entraîne deux roues dentées D1 et D2 (solidaires) qui roulent sur deux autres roues deutées El et 32 (séparées) tournant librement sur l'axe B. Variant 6: (fig 4) It is possible that the shaft A always drives the shaft B, even at low speed and with gear reduction, with no dead bridge possible. In this case the shaft A, by the axis C, drives two toothed wheels D1 and D2 (integral) which roll on two other deuterated wheels El and 32 (separated) freely rotating on the axis B.
Elles tournent à des vitesses différentes, les démultiplications étant différertes. E1 et E2 sont solidaires des planétaires I1 et I2 qui par l'intermédiaire des satellites J montes sur les aies K fixes sur l'arbre
B, entraînent cet arbre B à une vitesse différentielle. Le tout fait bloc (prise directe) quand lavitesse de A est suffisante pour que les
masses F ne tournent plus autour des axes C. Une roue libre L empêche la roue E2 de tourner en sens inverse. Celle-ci joue le rôle de point fixe ou point d'appui du levier.They rotate at different speeds, the gears being different. E1 and E2 are integral with the planets I1 and I2 which by means of the satellites J mount on the aies K fixed on the shaft
B, drive this shaft B at a differential speed. The whole unit (direct plug) when the speed of A is sufficient for the
masses F no longer rotate around axes C. A free wheel L prevents wheel E2 from turning in the opposite direction. This plays the role of fixed point or fulcrum of the lever.
Variante 7 : Une autre solution consiste à rendre la roue dentée El solidaire de l'arbre B. L'autre roue dentée E2 étant montée sur roue libre comme précédemment (fig F5). Variant 7: Another solution consists in making the toothed wheel El integral with the shaft B. The other toothed wheel E2 being mounted on a free wheel as before (fig F5).
Variante 8 : Il est possible de combiner plusieurs systèmes , en vue de résultats complémentaires. Variant 8: It is possible to combine several systems, for additional results.
Variante 9 : (fig 6). La masse excentrique (F2) peut être incorporée dans le pignon D, à la place ou en complément de la masse F1. Variant 9: (fig 6). The eccentric mass (F2) can be incorporated into the pinion D, in place of or in addition to the mass F1.
