Abstract

La présente invention concerne un embrayage automatique pour motocyclette comportant un disque avant (1), un disque arrière (2) et un disque intermédiaire (3). L'extrémité gauche du disque intermédiaire (3) est sous forme d'une paroi et forme une cavité conjointement avec la paroi du disque arrière (2) pour limiter le déplacement axial d'un disque entraîné (4) disposé du côté gauche. Une cavité abdominale du disque intermédiaire (3) est en articulation coaxiale et uniforme avec deux des six marteaux de volée (5). Un manche de marteau est disposé sur la partie gauche du marteau de volée (5) et un corps de marteau est disposé sur la partie droite. L'extrémité gauche du manche de marteau est munie d'un trou pivotant qui est articulé sur la base de l'articulation au niveau de la partie médiane du côté gauche du disque intermédiaire (3). Le côté gauche de la partie droite du corps de marteau est muni d'un doigt de pression (7) comprimé à l'extrémité droite d'un plateau de pression d'embrayage. Dans la cavité du corps de marteau de la partie droite il est prévu un piston à rappel (8) et un ressort de piston à rappel (9). L'extrémité supérieure sphérique du piston à rappel (8) se déplace en un mouvement alternatif sur une orbite d'une paroi de cavité d'un trou interne du disque intermédiaire (3). La force centrifuge à grande vitesse d'un moteur entraîne la compression d'un groupe de marteaux de volée contre un groupe de membranes d'embrayage (13) dans le disque arrière (2), pour transmettre la puissance à un disque de sortie connecté à une boîte de vitesses.
