Abstract
본 발명은 기관의 연소실에 장착되는 밸브들을 개폐하는 밸브구동장치에 관한 것으로서, 기관의 성능이 향상되도록 하기 위해, 밸브(31)가 개폐 가능하게 장착되는 오일통로가 형성되는 캠축(10)과, 상기 캠축의 일단부 외주면에 회전 가능하도록 끼워져 상기 오일통로와 연통되는 유로가 중심부에 형성되고 중심 동심원상으로 소정의 수납공간이 형성되는 캠축풀리(11)와, 상기 캠축풀리의 수납공간 내부에서 연동 가능하게 장치되어 상기 캠축의 위상각이 가변되도록 하는 타이밍가변장치(20)와, 상기 캠축의 밸브(31)에 조작 가능하게 연결되어 상기 타이밍가변장치의 동력전달과정을 제어하는 솔레노이드(30)와, 기관의 회전속도를 일정 비례값으로 연산처리하여 제어신호를 상기 솔레노이드에 출력하는 전자제어유니트(40)로 구성하여, 기관의 회전속도가 센서에 감지되어 전자제어유니트(40)에 입력되면, 전자제어유니트(40)에서 입력되는 기관의 회전속도를 일정 비례값으로 연산처리하여 일정 회전속도 이상에서 제어신호를 솔레노이드(30)에 인가하고, 솔레노이드(30)에 제어신호가 인가되면 캠축(10)의 유로에 장착되는 밸브(31)를 개구시켜 유로를 통해 일정 유압이 타이밍가변장치(20)에 작용되도록 하며, 타이밍가변장치(20)가 유압에 의해 일정각도 회전되어 캠축풀리(11)와 캠축(10) 사이에 위상각이 변하도록 하는 기관의 밸브 타이밍 가변장치이다.The present invention relates to a valve drive device for opening and closing the valves mounted in the combustion chamber of the engine, in order to improve the performance of the engine, the cam shaft 10 is formed with an oil passage in which the valve 31 is opened and closed, A camshaft pulley 11 interlocked with one end portion of the camshaft so as to be rotatable, the flow passage communicating with the oil passage is formed at the center thereof, and a predetermined storage space is formed in the center concentric circle. A timing variable device 20 capable of being mounted so that the phase angle of the cam shaft is variable, and a solenoid 30 operatively connected to the valve 31 of the cam shaft to control a power transmission process of the timing variable device; And an electronic control unit 40 which calculates and processes the rotational speed of the engine at a constant proportional value and outputs a control signal to the solenoid. Is detected by the sensor and input to the electronic control unit 40, the rotational speed of the engine input from the electronic control unit 40 is processed to a predetermined proportional value to apply a control signal to the solenoid 30 above the predetermined rotational speed. When the control signal is applied to the solenoid 30, the valve 31 mounted on the flow path of the camshaft 10 is opened so that a predetermined hydraulic pressure is applied to the timing variable device 20 through the flow path, and the timing variable device 20 is applied. ) Is a valve timing variable device of an engine which rotates a certain angle by hydraulic pressure so that the phase angle is changed between the camshaft pulley 11 and the camshaft 10.
