일반적으로, 밸브 트레인은 차량의 엔진등에서 밸브 트레인을 선택 구동케 제어함이 요구되며, 이를 위해서는 각종 센서등을 구비하여 제어하고 있다. 때문에 각종 센서로 부터의 테이타를 입력받아 대응하는 출력 테이타에 기록하여 구동순서 및 작동을 중앙 제어장치가 제어하는 방식이 주류를 이루는 바, 이들은 각종 센서와 대응하는 제어 프로그램이 필수적이어서 그 제어 설계 및 구현이 어려운 단점이 있다.In general, the valve train is required to control the selective drive of the valve train in the engine of the vehicle, etc., for this purpose, it is equipped with a variety of sensors and control. Therefore, the main method is that the central controller controls the driving sequence and operation by receiving data from various sensors and recording them in the corresponding output data.

본 고안은 이를 해결코자 하는 것으로, 트레인상의 밸브 구동용 캠에 의해 가변저항치를 선택토록 하는 피스톤을 작동시키고, 가변저항 전류에 따라 밸브 구동용 압축공기 및 유압을 유기적으로 제어토록 함을 특징으로 한다.The present invention is to solve this problem, by operating the piston to select the variable resistance value by the valve drive cam on the train, characterized in that to control the compressed air for driving the valve and the hydraulic pressure in accordance with the variable resistance current. .
즉, 본 고안은 트레인상의 밸브 구동용 캠과, 캠에 의해 피스톤 작용하며 피스톤 내벽에 가변저항과 오프 접점 스위치가 내장된 가변저항 피스톤과, 오프 접점 스위치가 온 될때 3웨이 밸브의 솔레노이드 구동용 솔레노이드 스위치와, 3웨이 밸브를 통해 공기압을 제공하는 컴프레서의 구동 스위치 접점을 가지는 릴레이부와, 상기 가변저항 피스톤의 선택전류갑에 의해 유압을 조절하는 유압조절기와, 상기 유압조절기의 조절유압으로 스프링에 의해 밸브 공을 차단하는 밸브를 열도록하며, 으로 이루어지는 엔진 밸브 트레인 구동장치를 제공하려는데 있다.That is, the present invention is a valve driving cam on a train, a variable resistance piston having a piston acting by a cam and having a built-in variable resistance and an off contact switch, and a solenoid driving solenoid of a three-way valve when the off contact switch is turned on. A relay unit having a switch, a drive switch contact of a compressor for supplying air pressure through a three-way valve, a hydraulic regulator for adjusting the hydraulic pressure by means of a selective current pack of the variable resistance piston, and an adjustment hydraulic pressure of the hydraulic regulator to the spring. It is intended to provide an engine valve train drive device consisting of opening the valve to block the valve ball by.
이하, 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the drawings.
제1도는 본 고안의 구성도로, 엔진 밸브 트레인 제어장치에 있어서, 밸브(1) 구동용 캠(2)과, 캠(2)에 의해 피스톤이 작용하며 피스톤 작용시 피스톤 내벽에 전류값을 구분시키는 가변저항(3)과, 오프 접점 스위치(4)가 온 될때 3웨이 밸브(6)의 솔레노이드(7) 구동용 솔레노이드 스위치(8)와, 3웨이 밸브(6)를 통해 공기압을 제공하는 컴프레서(9)의 구동 스위치(10) 접점을 가지는 릴레이부(11)와; 상기 가변저항 피스톤(5)의 선택 전류값에 의해 유압을 조절하는 유압조절기(12)와; 상기 유압조절기(12)의 조절유압으로 스프링(13)에 의해 밸브 공(14)을 차단하는 밸브(1)를 열도록 하며, 3웨이 밸브(6)을 통한 공기압으로 작동되는 유압 피스톤(15)으로 이루어진다.1 is a configuration diagram of the present invention, in the engine valve train control device, the piston (2) driving cam 2, the piston by the cam (2) acts to distinguish the current value on the inner wall of the piston when the piston acts A compressor for providing air pressure through the variable resistor 3, the solenoid switch 8 for driving the solenoid 7 of the three-way valve 6, and the three-way valve 6 when the off-contact switch 4 is turned on ( A relay section 11 having a drive switch 10 contact of 9); A hydraulic regulator 12 for adjusting the hydraulic pressure by the selected current value of the variable resistance piston 5; The hydraulic piston 15 is operated by pneumatic pressure through the three-way valve 6 to open the valve 1 to block the valve ball 14 by the spring 13 with the hydraulic pressure of the hydraulic regulator 12. Is done.
이와같이 구성하는 본원 고안의 동작을 설명하면, 엔진 구동축과 연동하는 캠(2)이 회전하면 로드(5-1)가 상승하게 되고 이때의 대응 가변저항(3)이 유압조절기(12)에 인가된다.Referring to the operation of the present invention configured as described above, when the cam (2) interlocked with the engine drive shaft is rotated, the rod (5-1) is raised and the corresponding variable resistor (3) at this time is applied to the hydraulic regulator 12 .
이렇게 캠(2)이 회전하여 제1도 같은 상태로 복귀하면 오프 접점 스위치(4)가 온되어 릴레이부(11) 전압(V)이 솔레노이드(7)에 인가되고, 컴프레서(9)를 구동시켜 3웨이 밸브(6)를 통해 유압피스톤(15)을 하강시킨다. 밸브스프링(16)의 텐션보다 큰 힘으로 유압피스톤(15)이 하강하면 밸브(1)가 하강하여 밸브 공(14)을 열고 연료를 주입하면 된다. 이때, 캠(2)은 밸브(1)에 대응하는 갯수로 구비하여 순차 구동함은 알 수 있을 것이다. 상기에서 유압조절기(14)는 유압을 조절하여 유압피스톤(15)의 작동 압력등을 제어함으로써 유압피스톤(15)의 밸브구동을 제어토록 한다.When the cam 2 rotates and returns to the same state as in FIG. 1, the off-contact switch 4 is turned on, and the relay unit 11 voltage V is applied to the solenoid 7 to drive the compressor 9. The hydraulic piston 15 is lowered through the three-way valve 6. When the hydraulic piston 15 descends with a force greater than the tension of the valve spring 16, the valve 1 descends to open the valve ball 14 and inject fuel. At this time, it will be appreciated that the cam 2 is provided in the number corresponding to the valve 1 and sequentially driven. The hydraulic controller 14 controls the valve drive of the hydraulic piston 15 by controlling the hydraulic pressure to control the operating pressure of the hydraulic piston 15.
상기와 같이 본원 고안은 엔진 밸브 트레인을 캠과 피스톤으로 제어하는 구조이므로 별도의 제어수단이 없어도 밸브를 구동시킬 수 있다.As described above, the present invention has a structure for controlling the engine valve train with a cam and a piston so that the valve can be driven without a separate control means.
