An automatically and smoothly continuously variable transmission, particularly for a bicycle, for transmitting input mechanical energy from a crank (80) to the drive wheel. A ratchet, having an oscillatory, alternating motion member (96) and a continuous rotary motion member (102), connected to the driven wheel, has a drive spring (82) drivingly linked between the ratchet alternating member and the crank for driving the ratchet alternating member in one direction of motion. A return spring (100) is linked to the ratchet alternating member for applying a return force upon the ratchet alternating member to return the alternating member in the opposite direction.
L'invention concerne une transmission variable en continu de façon automatique et sans heur, notamment, destinée à une bicyclette de manière à transmettre l'énergie mécanique d'entrée d'une manivelle à la roue motrice. Un rochet doté d'un élément mobile alternant, oscillatoire et d'un élément mobile rotatif en continu relié à la roue motrice présente un ressort d'entraînement lié de manière à être entraîner entre l'élément alternant du rochet et la manivelle d'entraînement de l'élément alternant du rochet dans une direction de déplacement. Un ressort de rappel est relié à l'élément alternant du rochet de manière à appliquer une force de retour sur l'élément alternant du rochet afin de retourner l'élément alternant dans la direction opposée.
