Abstract

엔진의 크랭크 축에 연결되어 회전하는 펌프와 대향배치되어 유체클러치로서 작용하는 터어빈을 보유하는 토오크 컨버터와, 이 토오크 컨버터의 유체 클러치 작용으로 회전하는 입력축의 회전을 유압제어부에 의해 작용하는 각각의 클러치 및 브레이크의 작동으로 전진 선기어, 후진선기어 및 유성제어장치를 선택적으로 회전시켜 1속 내지 4속의 감속비를 얻는 자동 변속기구에 있어서, 자동장치로 회전력을 전달하는 출력축(28)상에 설치되어 회전하는 드라이브 기어(32)를 보유하는 보조 오일펌프(31)를 설치하고, 상기한 보조 오일펌프(31)의 출구측을 주오일펌프(41)의 출구측으로 연결하여 토오크 컨버터(44)측으로 유압을 공급토록 함으로서 배출관로(49)(51)를 통하여 변속기구에 윤활유를 공급토록 하는 견인시 유입 공급수단을 구비한 자동 변속기구.A torque converter having a turbine connected to a rotating pump connected to the crank shaft of the engine and acting as a fluid clutch, and each clutch acting by the hydraulic control unit to rotate the input shaft rotated by the fluid clutch action of the torque converter. And an automatic transmission mechanism in which the forward sun gear, the reverse sun gear and the planetary control device are selectively rotated by operation of the brake to obtain a reduction ratio of 1 to 4 speeds, wherein the rotation is installed on the output shaft 28 which transmits the rotational force to the automatic device. An auxiliary oil pump 31 having a drive gear 32 is provided, and the outlet side of the auxiliary oil pump 31 is connected to the outlet side of the main oil pump 41 to supply hydraulic pressure to the torque converter 44 side. Automatic transmission mechanism with inflow supply means at the time of traction to supply lubricant to the transmission mechanism through the discharge pipe passages 49 and 51. .
