Abstract

무단의 변속폭을 크게 하여 동력을 효과적으로 이용할 목적으로; 각각 고종부재와 이동부재로 이루어져 동력원의 구동축과 종동축에 배치되어 벨트로서 연결되는 풀리로 이루어지는 제1 무단변속수단과; 상기 풀리의 일측으로 배치되어 상기 제1 변속수단의 무단 변속의 최고 변속비와 동일한 변속비를 갖도록 체인으로 연결되는 스프로켓과; 유성기어셋트로 이루어져 상기 1차 변속과 체인 스프로켓의 변속을 합성 또는 단속할 수 있는 제2 무단 변속수단을 포함하여 이루어지는 2단 변속시스템을 제공한다.To make effective use of power by increasing stepless speed; A first continuously variable means comprising a pulley which is composed of a high seed member and a movable member, respectively, and is formed on a drive shaft and a driven shaft of a power source and connected as a belt; A sprocket disposed on one side of the pulley and connected to a chain so as to have a speed ratio equal to a maximum speed ratio of the continuously variable speed of the first speed shift means; It provides a two-speed system consisting of a planetary gear set comprising a second continuously variable means for synthesizing or regulating the shift of the primary gear and the chain sprocket.
