Abstract

Electro-centrifugal clutch having discs associating a system of axial displacement generated by the pivoting of masses moved by centrifugal force, with an electromagnet whose excitation, or de-energising, allows the clutch to be coupled or uncoupled. The masses 5 act on the crown 9 which moves axially. The latter comes into contact with the receiving disc 6 which drives the shaft. The excitation of the electro-magnet 2 attracts the disc 3; the reception shaft is coupled. De-energising of the electro-magnet makes uncoupling possible.

Description

DESCRIPTION
EMBRAYAGE ELECTRO-CENTRIFUGE
L'invention concerne le domaine des transmissions de mouvements mécaniques.DESCRIPTION
ELECTRO-CENTRIFUGAL CLUTCH
The invention relates to the field of mechanical movement transmissions.

Elle a pour objet un embrayage particulier de type nouveau qui associe un dispositif centrifuge à disque et un électro-aimant. It relates to a particular new type of clutch which combines a centrifugal disc device and an electromagnet.

Elle permet de réaliser, à volonté, la liaison entre deux arbres situés sur un même axe, l'un étant l'arbre moteur, l'autre étant l'arbre récepteur. It allows to realize, at will, the connection between two shafts located on the same axis, one being the driving shaft, the other being the receiving shaft.

La relation entre ces deux arbres s'effectue par l'action de masses qui, pivotant sous l'action de la force centrifuge, mettent e n contact des disques garnis de matière anti-friction. Un électroaimant permet de rompre à volonté l'adhérence des disques, donc d'interrompre l'entrainement de l'arbre récepteur. The relationship between these two shafts is effected by the action of masses which, pivoting under the action of centrifugal force, bring into contact discs filled with anti-friction material. An electromagnet allows the adhesion of the discs to be broken at will, thus interrupting the drive of the receiving shaft.

Le fonctionnement est le suivant
Sous l'action de la force centrifuge, les masses (5) pivotent, agissent sur la couronne (9) qui les supporté en la faisant se déplacer axialement, celle-ci entre alors en contact avec le disque récepteur (6), lequel entraîne l'arbre sur lequel il est monté. La force de contact croit selon le carré de la vitesse de rotation et, l'entraînement est assuré grâce aux garnitures anti-friction.The operation is as follows
Under the action of centrifugal force, the masses (5) pivot, act on the crown (9) which supports them by making it move axially, this then comes into contact with the receiving disc (6), which drives the tree on which it is mounted. The contact force increases according to the square of the speed of rotation and, the drive is ensured thanks to the anti-friction linings.

Il est alors possible d'arrêter à volonté cet entraînement en commandant la mise hors tension d'un électro-aimant (2). It is then possible to stop this drive at will by controlling the switching off of an electromagnet (2).

Ce dispositif est particulièrement adapté aux transmissions susceptibles d'être fréquemment interrompues, c'est par exemple, le cas de l'embrayage d'une automobile dont le changement de vitesse exige un débrayage. This device is particularly suitable for transmissions likely to be frequently interrupted, this is for example the case of the clutch of an automobile whose change of speed requires a clutch.

Jusqu'à présent, les embrayages centrifuges étaient construits selon le principe général qui met en oeuvre le déplacement radial des masses liées à l'arbre moteur qui, sous l'effet de la force centrifuge entrent en contact avec la paroi interne d'un élément (carter, tambour, jante, etc...) qui est lié à l'arbre récepteur. Les masses pouvant être de nature diverse et guidées de différente façon. Until now, centrifugal clutches were built according to the general principle which implements the radial displacement of the masses linked to the drive shaft which, under the effect of centrifugal force come into contact with the internal wall of an element (casing, drum, rim, etc.) which is linked to the receiving shaft. The masses can be of diverse nature and guided in different ways.

I1 n'existe pas, à ce jour, d'embrayage centrifuge à disque, qui, associé à un électro-aimant permette d'obtenir la souplesse d'utilisation qu'offre la présente invention. De plus celle-ci permet une exécution peu coûteuse, grâce à sa simplicité qui se prête parfaitement à la production en grande série. Cet embrayage est léger et particulièrement interessant dans les cas ou la légèreté est recherchée.  I1 does not exist, to date, centrifugal disc clutch, which, associated with an electromagnet allows to obtain the flexibility of use offered by the present invention. In addition it allows inexpensive execution, thanks to its simplicity which lends itself perfectly to mass production. This clutch is light and particularly interesting in cases where lightness is sought.

La présente invention comporte, dans son principe - un disque solidaire d'un arbre moteur (1) - un électro-aimant (2) - un ensemble disque (3) - chappes (4) - masses (5) - et couronne
(9) monté fou en bout d'un arbre récepteur - un disque (6) lié en rotation à l'arbre récepteur, libre en translation
grâce aux cannelures. Ce disque est garni d'une matière anti-friction - un ensemble de ressorts (7) - les axes de pivotement des masses (8) - éventuellement un carter enfermant l'ensemble.The present invention comprises, in principle - a disc secured to a motor shaft (1) - an electromagnet (2) - a disc assembly (3) - caps (4) - masses (5) - and crown
(9) mounted idly at the end of a receiving shaft - a disc (6) linked in rotation to the receiving shaft, free in translation
thanks to the grooves. This disc is lined with an anti-friction material - a set of springs (7) - the pivot axes of the masses (8) - possibly a casing enclosing the whole.

L'invention sera mieux comprise en se reportant au dessin schématique annexé qui donne à titre d'exemple et non limitativement un mode de réalisation de ladite invention. The invention will be better understood by referring to the appended schematic drawing which gives by way of example and without limitation an embodiment of said invention.

On ne sortira pas du cadre de l'invention quelque soit les formes, les dimensions, les proportions des différents éléments constitutifs de l'invention, éléments qui pourraient être obtenus en toute matière ou combinaison de matières,subir tout traitement.  It will not depart from the scope of the invention whatever the shapes, the dimensions, the proportions of the various constituent elements of the invention, elements which could be obtained in any material or combination of materials, undergo any treatment.
