Abstract

연속 가변 비율 변속기는 비율 가변 유니트("가변기") 및 동심적으로 배열된 세 개의 출력을 가진 유성 유니트를 포함한다. 상기 출력중 둘은 가변기의 양쪽단부에 고정된 비율로 각각 연결되며, 따라서 가변기 비율이 변화될 때, 이들 출력중 하나의 속도는 항상 상승하며 나머지는 떨어진다. 이들 두 출력은 적당한 기어링과 클러치에 의하여 CVT출력축에 연결된다. 전체 CVT의 비율 범위를 확장하는 연속적인 동작의 기어비는 두유성 출력 각각을 CVT 출력에 선택적으로 연결시킴으로써 얻어진다. 비율 및 다른 파라미터는 기어비 변화가동기적으로 되도록 선택된다.
