Abstract

본 발명은 변속기의 구성부분을 이루는 무단변속기구에 관한 것으로, 하나의 유성기어유닛(1)과 토오크를 변화시키는 토오크컨버터(2)로 구성되면서, 상기 유성기어유닛(1)의 선기어(3)에 동력원이 입력축(5)을 통해 연결되고, 상기 선기어(3)의 둘레에 소정의 간격을 두고 배치된 다수개의 피니언기어(6)가 피니언캐리어(7)를 매개하여 토오크컨버터(2)의 임펠러(8)와 연결되어 있으며, 상기 임펠러(8)로부터 동력을 전달받아 회전하게 되는 토오크컨버터(2)의 터어빈(9)은 상기 유성기어유닛(1)의 링기어(10)와 연결되어 있는 한편, 상기 링기어(10)는 링기어축(11)과 출력축(12)을 매개하여 차동기어(13)와 연결된 구조로 이루어져, 엔진에서 전달되는 동력이 출력축에 가해지는 부하의 크기에 따라 자동적으로 제어되면서, 상기 부하에 알맞는 크기로 출력되어지도록 되어 있다.The present invention relates to a continuously variable transmission mechanism that forms a constituent part of a transmission, and comprises one planetary gear unit (1) and a torque converter (2) for changing torque, and the sun gear (3) of the planetary gear unit (1). The power source is connected via the input shaft 5, and a plurality of pinion gears 6 arranged at predetermined intervals around the sun gear 3 are connected to the pinion carriers 7 via the impeller of the torque converter 2. It is connected to (8), the turbine (9) of the torque converter (2) is rotated by receiving power from the impeller (8) is connected to the ring gear (10) of the planetary gear unit (1) The ring gear 10 has a structure connected to the differential gear 13 through the ring gear shaft 11 and the output shaft 12, so that the power transmitted from the engine is automatically applied according to the magnitude of the load applied to the output shaft. While being controlled, it may be output in a size suitable for the load It is locked.
