Abstract

La transmission transforme le mouvement d'aller et retour d'une pédale 8 en rotation d'un arbre de sortie, par un câble 10 fixé directement au levier 1 permettant le mouvement oscillant de la pédale. Ce câble s'enroule sur un cylindre 12 entraînant l'arbre de sortie par une roue libre. A l'aller, la tension du câble provoque la rotation de l'arbre de sortie, et au retour, un rappel élastique permet à la pédale de reprendre sa position d'origine sans faire tourner l'arbre de sortie en sens inverse grâce à la roue libre. Cette transmission très légère, fiable, propre et simple est très efficace parce que le rapport de couple varie peu au cours d'un cycle. Un moyen simple permet de faire varier en continu le rapport de transmission, aussi bien sur commande de l'utilisateur qu'en fonction de la variation du couple résistant.The transmission transforms the back and forth movement of a pedal 8 into rotation of an output shaft, by a cable 10 fixed directly to the lever 1 allowing the oscillating movement of the pedal. This cable is wound on a cylinder 12 driving the output shaft by a free wheel. On the go, the tension of the cable causes the rotation of the output shaft, and on the return, an elastic return allows the pedal to return to its original position without turning the output shaft in the opposite direction thanks to freewheeling. This very light, reliable, clean and simple transmission is very efficient because the torque ratio varies little during a cycle. A simple means makes it possible to continuously vary the transmission ratio, both on command of the user and as a function of the variation of the resisting torque.
