A chainless drive system for a bicycle, according to the present invention, comprises: a gear housing (50) including a crank shaft (40) having a crank (38) mounted thereon, an input gear shaft (60a) spaced apart from the crank shaft (40) and having an input gear (65) mounted on one side thereof, and an output gear shaft (60b) having an output part (55) mounted on an opposite side thereof; a rear shaft (140) having a rear-shaft gear (142) mounted on one side thereof; a connecting gear (152) engaged with the rear-shaft gear (142) and disposed so as to be rotatable relative to a link stay (155); and a plurality of links (150) between the output part (55), which is mounted on the output gear shaft (60b) of the gear housing (50), and the connecting gear (152), the links (150) being rotatable and being connected and arranged parallel to one another, wherein the plurality of links (150) are configured to rotate to an oblique angle in the longitudinal and lateral directions according to rotation of the crank shaft (40) without interference therebetween.

    La présente invention concerne un système d'entraînement sans chaîne pour une bicyclette qui comprend : un carter d'engrenage (50) comprenant un vilebrequin (40) sur lequel est montée une manivelle (38), un arbre d'engrenage d'entrée (60a) espacé du vilebrequin (40) et ayant un engrenage d'entrée (65) monté sur son côté et un arbre d'engrenage de sortie (60b) ayant une partie de sortie (55) monté sur son côté opposé ; un arbre arrière (140) ayant un engrenage (142) d'arbre arrière monté sur son côté ; un engrenage de liaison (152) en prise avec l'engrenage (142) d'arbre arrière et disposé de manière à pouvoir tourner par rapport à un hauban de liaison (155) ; et une pluralité de liaisons (150) entre la partie de sortie (55), qui est montée sur l'arbre d'engrenage de sortie (60b) du carter d'engrenage (50) et l'engrenage de liaison (152), les liaisons (150) pouvant tourner et étant reliées et agencées parallèles les unes aux autres, la pluralité de liaisons (150) étant conçues pour tourner selon un angle oblique dans les directions longitudinale et latérale selon la rotation du vilebrequin (40) sans interférence entre ces éléments.

    본 발명의 자전거용 무체인 구동계는 크랭크(38)가 끼워지는 크랭크축(40)과, 상기 크랭크축(40)에 간격을 두고 배치되며 일측에 입력기어(65)가 끼워지는 입력기어축(60a)과 타측에 출력부(55)가 끼워지는 출력기어축(60b)을 구비한 기어 하우징(50)과; 일측에 뒷축기어(142)가 끼워지는 뒷축(140)과; 상기 뒷축기어(142)와 치합되고, 링크 스테이(155)에 회전 가능하게 배치된 연결기어(152)와; 상기 기어 하우징(50)의 출력기어축(60b)에 끼워진 출력부(55)와 상기 연결기어(152)의 사이에 회동 가능하고 서로 평행하게 연결 배치된 복수개의 링크(150)를 포함하며, 상기 복수개의 링크(150)는 크랭크축(40)의 회전에 따라 경사진 각도로 종방향과 횡방향으로 서로 간섭되지 않게 회동하도록 구성된다.
