Abstract

본 발명은 유성기어장치와 베인펌프형 유체클러치를 조합시킨 자동변속장치에 관한 것이다.The present invention relates to an automatic transmission in which a planetary gear device and a vane pump type fluid clutch are combined.

자동변속장치의 구조가 간단하고 장치의 제어가 용이하며 토크 전달용량이 크기 때문에 시내버스와 같은 대형 차량에 탑재 가능하다.Because of the simple structure of the automatic transmission, the control of the device is easy, and the torque transmission capacity is large, it can be mounted on large vehicles such as city buses.

유성기어장치의 선기어(1)에 엔진의 동력을 전달하고, 링기어(4)의 역회전을 억제하는 방향으로 그 힘이 작용하는 베인펌프형 유체클러치를 통해 링기어에 부하되는 반력을 뒷받침하여 주며, 링기어(4)의 역회전 회전속도의 변화에 따라 유성캐리어의 회전력과 회전속도가 변화된다.It supports the reaction force loaded on the ring gear through the vane pump type fluid clutch which transmits the engine power to the sun gear 1 of the planetary gear device and suppresses the reverse rotation of the ring gear 4. The rotational force and the rotational speed of the planetary carrier are changed according to the change of the reverse rotational rotational speed of the ring gear 4.
