Abstract

Embrayage à roue libre à cliquets multiples, comprenant un rochet d'entraînement (1, 5), un cliquet (2, 6), un élément élastique (3, 7), un siège de cliquet (4, 8), et un ensemble rochet entraîné. L'ensemble rochet entraîné comprend un premier rochet entraîné (11, 51) et un second rochet entraîné (12, 52) ; lorsque l'embrayage à roue libre à cliquets multiples tourne le long d'une direction de ralenti, le rochet d'entraînement (1, 5) entraîne le premier rochet entraîné (11, 51) et le second rochet entraîné (12, 52) en rotation, de sorte que les sommets des dents du premier rochet entraîné (11, 51) et les sommets des dents du second rochet entraîné (12, 52) sont complémentaires dans la direction axiale, le cliquet se déplace sur les sommets des dents du premier rochet entraîné (11, 51) et les sommets des dents du second rochet entraîné (12, 52), et le cliquet (2, 6) n'entre pas en contact avec le rochet d'entraînement (1, 5).
