Abstract

L'invention concerne un ensemble de transmission à vitesses multiples comprenant une première roue dentée (5) entraînée pour tourner à une première vitesse, une deuxième roue dentée (9) entraînée pour tourner à une deuxième vitesse et un arbre (2). Les première (5) et deuxième (9) roues dentées sont montées sur l'arbre (2) et peuvent tourner par rapport à celui-ci. Des moyens de blocage (3, 4, 7) servent à bloquer chaque roue dentée (5, 9) séparément sur l'arbre (2). Les moyens de blocage comprennent un élément de blocage (3) se déplaçant radialement vers l'intérieur et vers l'extérieur de l'arbre (1) et des moyens d'actionnement (1, 7, 4) servant à déplacer l'élément de blocage (3) radialement vers l'extérieur de l'arbre (2) pour qu'il s'engage dans la première (5) ou la deuxième roue dentée (9), et radialement vers l'intérieur de l'arbre (2) pour qu'il libère la roue dentée concernée (5; 9).
