Abstract

본 발명은 산업장비의 동력전달장치에 있어서 출력되는 동력을 임의적으로 변속하여 주도록 하되 기어변환 없이 변속비를 무단계로 변속이 가능하며 따라서 변속시 입력되는 동력을 차단시키지 않고 변속이 가능하도록한 무단 변속장치에 관한 것으로 서로 연결작동되는 2단의 차동장치와 상기 각 차동장치 사이를 서로 다른 감속비를 갖는 고변속부와 저변속부로 이루어진 기어배열을 통하여 동시 연결 작동되도록 하되 동시 작동되는 역학관계에 의하여 변속기능이 이루어지도록 하는 것이다. 따라서 종래의 자동변속기의 경우보다 다소 간단하며 최적의 변속비로 엔진의 출력을 전달하므로 영ㄴ비 및 경제성 향상에 도움을 줄 수 있으며 차량의 승차감 향상 및 운전의 편의성을 가져다 준다.The present invention is to continuously change the power output in the power transmission device of the industrial equipment, but the speed ratio can be shifted steplessly without gear shifting, and thus continuously variable speed transmission without interrupting the power input during transmission It relates to a two-stage differential device that is connected to each other and the differential operation between each of the differential gears through a gear arrangement consisting of a high speed gear and a low speed gear having a different reduction ratio, but the shift function by the dynamics operating simultaneously To make this happen. Therefore, it is somewhat simpler than in the case of the conventional automatic transmission, and can transmit the output of the engine at the optimum transmission ratio, which can help improve the efficiency and economy, and bring the comfort of the vehicle and the convenience of driving.
