Title (EN) BICYCLE CRANK TRANSMISSION APPARATUS
(FR) APPAREIL DE TRANSMISSION À PÉDALIER DE BICYCLETTE
(KO) 자전거 크랭크 변속장치
Abstract:
(EN) The present specification discloses a bicycle crank transmission apparatus that can implement a transmission mechanism using a single chain ring. An embodiment of the aforementioned bicycle crank transmission apparatus comprises: an axial member having an empty space formed therein; a base plate having one side surface coupled with the axial member and an opposite side surface secured to a bottom bracket provided with a spindle; a chain ring housing coupled to the axial member so as to be rotatable and having a ring gear fixedly installed therein; a speed reduction gear unit disposed in the center of the ring gear; a directly-coupled ratchet unit installed on the ring gear; a crank cover having, in the center thereof, a vertical coupling shaft coupled with the spindle and, on the inner wall surface thereof, clutch ratchet saw teeth and directly-coupled ratchet saw teeth formed in parallel in the height direction; and a sun gear mounted on the coupling shaft to rotate only in the clockwise direction.
(FR) La présente invention concerne un appareil de transmission à pédalier de bicyclette, lequel appareil peut mettre en œuvre un mécanisme de transmission utilisant un seul plateau de chaîne. Dans un mode de réalisation, l'appareil de transmission à pédalier de bicyclette comprend : un élément axial ayant un espace vide formé dans ce dernier; une plaque de base ayant une surface latérale accouplée à l'élément axial et une surface latérale opposée fixée à un support inférieur comportant un arbre rotatif; un carter de plateau de chaîne couplé à l'élément axial de manière à pouvoir tourner et ayant une couronne dentée installée de façon fixe à l'intérieur de ce dernier; une unité d'engrenage de réduction de vitesse disposée au centre de la couronne dentée; une unité de rochet à couplage direct installée sur la couronne dentée; un capot de pédalier ayant, au centre de ce dernier, un arbre de couplage vertical couplé à l'arbre rotatif, et, sur la surface de paroi interne de ce dernier, des dents de scie de rochet d'embrayage et des dents de scie de rochet à couplage direct formées en parallèle dans la direction de la hauteur; et une roue solaire montée sur l'arbre de couplage pour tourner uniquement dans le sens des aiguilles d'une montre.
