이하, 본 발명의 일 실시예를 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 자동차용 반자동 유압작동식 변속장치의 구성을 도식적으로 나타낸 도면으로서, 본 발명의 일 실시예에 따른 반자동 유압작동식 변속기의 동력 단속장치는, 전자제어유니트(1)에 연결되어 변속 레버(2)에 장착된 클러치 작동 스위치(3)의 온(on)시 전자계어유니트(1)의 제어신호에 따라 유압이 공급될 수 있도록 유압 라인(4)을 개방하여 클러치(5)를 끊는 제1마그네틱 밸브(6)와, 변속기(7)에 장착되어 클러치(5)의 끊김을 검출하는 액튜에이터 피스톤 위치검출센서(8)와, 상기 액튜에이터 피스톤 위치검출센서(8)에 의해 검출된 검출신호가 전자제어유니트(1)에 전달됨에 따라 전자제어유니트(1)에 변속 레버(2)의 레버위치를 검출하여 전달하는 변속레버 위치검출센서(9)와, 상기 변속레버 위치검출센서(9)의 레버위치 검출신호에 따라 변속이 수행된 후, 전자제어유니트(1)의 제어에 따라 유압이 배출되도록 유압 라인(4)을 개방시켜 클러치(5)를 다시 접속시키는 제2 및 제3마그네틱 밸브(10, 11)와, 상기 제1마그네틱 밸브(6)와 제2 및 제3마그네틱 밸브(10, 11)가 설치된 유압 라인(4)에 연결되어 제1마그네틱 밸브(6)의 개방시 펌핑작용에 의해 유압을 공급하는 한편, 제2 및 제3마그네틱 밸브(10, 11)의 개방시 펌핑작용에 의해 유압을 배출시키는 펌프(12)와, 상기 펌프(12)에 연결되는 오일 탱크(13)로 구성된다.1 is a diagram schematically showing the configuration of a semi-automatic hydraulically actuated transmission for a vehicle according to the present invention, wherein the power control device of the semi-automatic hydraulically actuated transmission according to the embodiment of the present invention is provided in the electronic control unit 1. When the clutch operation switch 3 connected to the shift lever 2 is turned on, the hydraulic line 4 is opened to open the hydraulic line 4 so that the hydraulic pressure can be supplied according to the control signal of the electronic gear unit 1. Is detected by the first magnetic valve (6) cutting off the actuator, the actuator piston position detecting sensor (8) mounted on the transmission (7), and detecting the disconnection of the clutch (5), and the actuator piston position detecting sensor (8). The shift lever position detection sensor 9 detects and transmits the lever position of the shift lever 2 to the electronic control unit 1 as the detected detection signal is transmitted to the electronic control unit 1, and the shift lever position detection sensor. According to the lever position detection signal in (9) After the operation is performed, the second and third magnetic valves 10 and 11 which reconnect the clutch 5 by opening the hydraulic line 4 so that the hydraulic pressure is discharged under the control of the electronic control unit 1, and the It is connected to the hydraulic line 4 provided with the first magnetic valve 6 and the second and third magnetic valves 10 and 11 to supply hydraulic pressure by a pumping action when the first magnetic valve 6 is opened. It consists of a pump 12 for discharging hydraulic pressure by the pumping action when the second and third magnetic valves 10 and 11 are opened, and an oil tank 13 connected to the pump 12.

이때, 클러치(5)를 접속시키는 제2 및 제3마그네틱 밸브(10, 11)는 제2마그네틱 밸브(10)가 제3마그네틱 밸브(11)보다 큰 오리피스 직경을 가지도록 구성되어, 초기 출발시에는 오리피스 직경이 작은 제3마그네틱 밸브(11)를 통해 유압이 배출되어 클러치(5)의 접속이 천천히 이루어지도록 하고, 가속시에는 오리피스 직경이 큰 제2마그네틱 밸브(10)를 통해 유압이 배출되어 클러치(5)의 접속이 급속히 이루어지도록 하고 있다.At this time, the second and third magnetic valves 10 and 11 connecting the clutch 5 are configured such that the second magnetic valve 10 has a larger orifice diameter than the third magnetic valve 11, so In this case, the hydraulic pressure is discharged through the third magnetic valve 11 having a small orifice diameter so that the clutch 5 is connected slowly, and during acceleration, the hydraulic pressure is discharged through the second magnetic valve 10 having a large orifice diameter. The clutch 5 is connected rapidly.

이와 같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

클러치 작동 스위치(3)의 온(on)시, 전자제어유니트(1)는 제1마그네틱 밸브(6)를 제어하여, 유압을 공급함으로써 신속하게 클러치(5)를 떼어 놓는다.When the clutch operation switch 3 is turned on, the electronic control unit 1 controls the first magnetic valve 6 to quickly release the clutch 5 by supplying hydraulic pressure.

이에 따라, 액튜에이터 피스톤 위치검출센서(8)로는 클러치(5)의 작동을 감지하여 클러치(5)의 작동이 완료되면 전자제어유니트(1)에 검출신호를 보내게 되며, 변속 레버(2)에 장착된 변속레버 위치검출센서(9)는 레버의 위치를 검출한 신호를 전자제어유니트(1)로 보내게 된다.Accordingly, the actuator piston position detection sensor 8 detects the operation of the clutch 5, and when the operation of the clutch 5 is completed, sends a detection signal to the electronic control unit 1, and transmits to the shift lever 2. The shift lever position detection sensor 9 mounted sends a signal detecting the position of the lever to the electronic control unit 1.

따라서, 변속기(7)에서는 전자제어유니트(1)의 제어에 따라 변속이 수행된다.Therefore, the transmission 7 is shifted under the control of the electronic control unit 1.

변속이 완료되면 제2 및 제3마그네틱 밸브(10, 11)가 열려 펌핑작용에 의해 유압이 배출됩으로써 클러치(5)의 접속이 이루어지게 된다.When the shift is completed, the second and third magnetic valves 10 and 11 are opened so that the hydraulic pressure is discharged by the pumping action, so that the clutch 5 is connected.

한편, 클러치(5)를 접속시키는 제2 및 제3마그네틱 밸브(10, 11)중 제3마그네틱 밸브(11)가 초기 출발시에 그 밸브를 통해 유압이 배출되게 하여 클러치(5)의 접속이 천천히 이루어지도록 하고, 가속시에는 제2마그네틱 밸브(10)를 통해 유압이 배출되게 하여 클러치(5)의 접속이 급속히 이루어지도록 한다.On the other hand, of the second and third magnetic valves 10 and 11 connecting the clutch 5, the third magnetic valve 11 causes the hydraulic pressure to be discharged through the valve at the initial start so that the connection of the clutch 5 is performed. When the acceleration is made slowly, the hydraulic pressure is discharged through the second magnetic valve 10 to accelerate the connection of the clutch 5.

따라서, 본 발명은 공압보다 제어가 용이한 유압을 이용하여 클러치(5)의 단속 작용을 보다 정확하고 미세하게 조절할 수 있게 된다.Therefore, the present invention can more precisely and finely control the intermittent action of the clutch 5 by using hydraulic pressure that is easier to control than pneumatic pressure.

이상에서와 같이, 본 발명은 차량의 반자동 유압작동식 변속장치의 클러치(5)의 동작이 보다 정확하고 정밀하게 이루어질 수 있도록 하여 반자동유압작동식 변속장치를 장착한 차량의 변속성능이 보다 향상될 수 있도록 한 매우 유용한 발명이다.As described above, the present invention enables the operation of the clutch 5 of the semi-automatic hydraulically actuated transmission of the vehicle to be made more accurately and precisely so that the shift performance of the vehicle equipped with the semi-automatic hydraulic actuated transmission is more improved. One very useful invention that makes it possible.
