Description
Claims (3)
- 선기어(1)를 중심으로 3개의 유성기어(2)가 유성기어캐리어(4)로 지지되어 물려지고 그 외주에 링기어(3)가 맞물린 구조로 이루어진 유성기어장치의 상기 선기어(1)가 엔진회전력이 전달되는 풀리샤프트(8)의 단부에 고정되고, 상기 유성기어캐리어(4)는 캠샤프트(9)의 단부에 고정되는 한편, 회전축에 웜(5)이 장착된 모터(6)가 구비되고, 이 모터(6)의 웜(5)은 상기 유성기어장치의 링기어(3) 외주면에 형성된 웜기어(3a)에 치합되는 구조로 이루어진 자동차 엔진의 밸브타이밍 가변기구.
- 제 1항에 있어서, 상기 모터(6)는 밸브타이밍이 맵핑된 엔진제어유니트(10)에 의해 작동제어되는 것을 특징으로 하는 자동차 엔진의 밸브타이밍 가변기구.
- 제 2항에 있어서, 상기 엔진제어유니트(10)는 밸브타이밍의 지각조절이 필요할 경우 모터(6)를 정방향으로 작동시켜 링기어(3)를 순방향으로 회전시키고, 진각조절이 필요할 경우에는 모터(6)를 역방향으로 작동시켜 링기어(3)를 역방향으로 회전키도록 된 것을 특징으로 하는 자동차 엔진의 밸브타이밍 가변기구.
