Abstract

클러치 2개와 브레이크 3개를 마찰요소로 사용하는 자동변속기의 변속장치에 있어서 부변속 수단을 사용하지 않고 4속의 변속단을 실현하기 위하여, 엔진의 회전 동력을 토오크 컨버터를 통하여 전달받는 입력축과, 입력요소 또는 반력요소로 선택될 수 있는 선기어와 출력축으로 동력을 전달하는 유성 캐리어를 공용으로 하는 첫번째 및 두번째 단순 유성기어셋트와, 상기한 유성기어셋트들의 어느 한 요소 또는 2개의 요소로 상기한 입력축의 동력을 선택적으로 전달하는 1개 이상의 마찰요소와, 상기한 유성기어셋트들의 어느 한 요소 또는 2개의 요소를 반력요소로 선택하는 1개 이상의 마찰요소를 포함하는 차량용 자동변속기의 파워트레인을 제공한다.In the transmission of the automatic transmission using two clutches and three brakes as friction elements, the input shaft receives the rotational power of the engine through the torque converter to realize the four-speed shift stage without using a sub-shift means. The first and second simple planetary gearsets, which share a sun gear that can be selected as an element or a reaction element, and a planetary carrier that transmits power to the output shaft, and any one or two elements of the planetary gearsets described above. A powertrain for a vehicular automatic transmission comprising at least one friction element for selectively transmitting power and at least one friction element for selecting one or two elements of the planetary gear sets as reaction elements.
