Abstract

간단하고 밸브의 개폐 타이밍화 밸브의 리프트 조정을 동시에 할 수 있도록 하기 위하여 일측(도면에서 좌측)으로부터 타측으로 갈수록 리프트가 커지는 형태 즉, 노즈가 경사지게 형성되는 프로파일을 보유하는 다수의 캠이 축방향 등간격으로 배치되는 메인축과, 상기 메인축의 일측부에 메인축의 축방향 이동시 위상각이 변화할 수 있도록 헤리컬 기어로 결합되는 스프로켓축을 포함하여 구성되는 캠축과; 상기 메인축의 후단에 배치되어 전자제어장치의 제어에 의하여 상기 메인축을 축방향으로 이동시키는 솔레노이드 제어기로 형성되는 구동수단을 포함하여 이루어짐으로써, 밸브의 리프트 및 개폐 타이밍이 가변되도록 구성한 내연기관의 가변 타이밍 밸브 구동장치.Simple and open / close timing of the valve In order to allow simultaneous adjustment of the lift of the valve, a plurality of cams having a profile in which the lift is inclined from one side (left in the drawing) to the other side, that is, the nose is inclined are formed in the axial direction. A cam shaft including a main shaft disposed at an interval, and a sprocket shaft coupled to the helical gear so that a phase angle of the main shaft can be changed at one side of the main shaft; And a driving means disposed at a rear end of the main shaft and formed as a solenoid controller for moving the main shaft in the axial direction by the control of the electronic controller, thereby changing the timing of lift and opening and closing of the valve. Valve drive.
