Abstract

Ce dispositif sert à actionner un axe de commande (30) fonctionnellement relié à un mécanisme de transmission (10) à vitesses multiples monté dans l'axe du pédalier d'une bicyclette ou similaire. L'axe de commande (30) est coaxialement monté dans un arbre moteur (35) pourvu à au moins une extrémité d'une manivelle (1, 2) de pédalier assujettie en rotation. Afin de pouvoir changer les vitesses, un premier organe d'accouplement (23) monté sur l'arbre moteur (35) peut être déplacé dans le sens axial par l'axe de commande (30) de façon à mettre les éléments de transmission de force du mécanisme de transmission (10) en prise par liaison de forme et de force. Un corps de commande (45) fonctionnellement relié à l'axe de commande (30) par un deuxième organe d'accouplement (40) est monté à l'autre extrémité de l'arbre d'entraînement pour assurer un déplacement en sens axial. Lorsque le corps de commande (45) est mis en rotation autour de l'axe longitudinal (X) par rapport à une partie formant boîtier (25) et pourvue d'au moins un régulateur (27), il peut se déplacer en sens axial. Le corps de commande (45) peut être mis en rotation par exemple par un organe d'actionnement qui lui est fonctionnellement relié et qui peut pivoter autour de l'axe longitudinal (X).
