본 발명은 차량의 급발진 제어용 솔레노이드에 관한 것으로서, 더욱 상세하게는 자기력을 증가시키기 위하여 플런저의 구조가 개선된 차량의 급발진 제어용 솔레노이드에 관한 것이다.The present invention relates to a sudden start control solenoid of a vehicle, and more particularly, to a sudden start control solenoid of a vehicle having an improved structure of a plunger to increase a magnetic force.

일반적으로 차량에는 차량의 감속 또는 정지를 목적으로 각 바퀴측에 설치되는 휠실린더와, 제동압을 형성하여 휠실린더 측으로 전달하는 부스터 및 마스터실린더 등이 장착되어 있어서, 운전자가 브레이크페달을 밟으면 마스터실린더에서 형성된 제동압이 휠실린더로 전달되어 제동력이 발생된다. 그러나 이러한 제동작용 중에는 바퀴가 멈춰진 상태에서도 차가 여전히 진행하여 노면에서 미끄러지는 슬립현상이 흔히 발생된다.In general, the vehicle is equipped with a wheel cylinder installed on each wheel side for the purpose of decelerating or stopping the vehicle, and a booster and a master cylinder for forming a braking pressure and transmitting it to the wheel cylinder side. The braking pressure generated at is transmitted to the wheel cylinder to generate a braking force. However, during this braking operation, slipping occurs on the road even when the wheels are stopped.

따라서 최근에는 이러한 슬립 현상을 효율적으로 방지하여 강력하고 안정된 제동력을 발휘하여 운전조작을 보다 용이하게 하기 위해 제동시 바퀴의 미끄러짐을 방지하는 안티록 브레이크 시스템(anti-rock brake system)과, 제동시 뿐만 아니라 차량의 급발진시나 급가속시 구동륜의 과도한 슬립을 방지하는 브레이크 트랙션 제어 시스템(brake traction control system)이 개발되고 있다.Therefore, in recent years, in order to effectively prevent such slip phenomenon and to exhibit a strong and stable braking force to make driving easier, an anti-rock brake system that prevents slippage of the wheel during braking and In addition, a brake traction control system has been developed to prevent excessive slippage of the driving wheel during rapid start or acceleration of a vehicle.

이러한 브레이크 트랙션 제어 시스템에 사용되는 솔레노이드밸브(1)는 도 1에서와 같이, 전류가 인가되면 자기장을 형성하는 코일(12)이 권선되는 보빈(bobbin:10)이 개구된 중공부를 가지며 설치되고, 보빈(10)의 후측에 플레이트(20)가 삽입 설치되며, 보빈(10)의 전방측으로 브라켓(30)이 설치되고, 브라켓(30)의 내측으로 바텀(bottom:40)이 부시(42)와 같이 설치된다.The solenoid valve 1 used in the brake traction control system is provided with a hollow portion having an opening bobbin (10), in which a coil 12, which forms a magnetic field, is wound, as shown in FIG. Plate 20 is inserted into the rear side of the bobbin 10, the bracket 30 is installed to the front side of the bobbin 10, the bottom (bottom: 40) to the inside of the bracket 30 and the bush 42 It is installed together.

그리고 보빈(10)의 중공부에 일체로 연동되는 케이블(cable:60)과 플런저(plunger:50)가 설치되고, 플런저(50)의 후측으로는 충격 흡수용 댐퍼(70)가 스프링(72)과 같이 설치된다. A cable 60 and a plunger 50 integrally interlocked with the hollow part of the bobbin 10 are installed, and a shock absorbing damper 70 is provided at the rear side of the plunger 50 with a spring 72. It is installed as follows.

위와 같은 솔레노이드(1)의 작동을 설명하면, 코일(12)에 전류가 인가되어 자기장이 발생하면, 자속이 보빈(10)의 브라켓(30)과 바텀(40)을 따라 흐르게 되고, 이에 반대 극성을 가지는 플런저(50)가 케이블(60)과 같이 댐퍼(70)의 스프링(72)을 압축시키면서 전진 이동된다. 따라서 전진 이동된 케이블(60)은 미도시된 레버를 록킹상태로 고정시켜서 차량의 급발진을 방지하게 된다.Referring to the operation of the solenoid 1 as described above, when a current is applied to the coil 12 to generate a magnetic field, the magnetic flux flows along the bracket 30 and the bottom 40 of the bobbin 10, the opposite polarity Plunger 50 having a forward movement while compressing the spring 72 of the damper 70, such as the cable (60). Therefore, the forwarded cable 60 is fixed to the lever not shown in the locked state to prevent the sudden start of the vehicle.

그리고 코일(12)의 전류가 차단되면, 스프링(72)의 탄성력에 의해 댐퍼(70) 및 플런저(50)와 케이블(60)이 후퇴된다.When the current of the coil 12 is cut off, the damper 70, the plunger 50, and the cable 60 are retracted by the elastic force of the spring 72.

이와 같이 구동하는 솔레노이드는 그 크기가 클수록 자기력이 증대되어 바텀과에 대한 플런저의 응답 속도가 증가될 수 있지만, 크기를 무한정 키울 수 없는 관계로 종래에는 요구된 힘의 크기만큼 플런저의 길이를 선택했다. 또한 바텀과 마주하는 플런저의 끝단을 경사지게 형성시켜 안정적 운동을 만들어냈다. 하지만 플런저의 직선운동시 그 응답속도를 증가시키기 위해서는 플런저가 받는 자기력의 증가가 요구되며, 낮은 전압, 전류 및 적은 코일의 권선 수에서도 큰 힘을 유지하여 안정된 응답속도를 만들어 낼 필요가 있다.The larger the size of the solenoid is, the more the magnetic force increases, so the response speed of the plunger to the bottom can be increased. . In addition, the end of the plunger facing the bottom is inclined to form a stable motion. However, in order to increase the response speed during linear movement of the plunger, an increase in the magnetic force received by the plunger is required, and it is necessary to maintain a large force even at low voltage, current, and a small number of coil turns to produce a stable response speed.

본 발명은 상기한 바와 같은 문제점을 개선시키기 위하여 안출된 것으로, 플런저의 후측 끝단부에 자기력보강수단을 설치함으로써, 자기력이 증가된 플런저는 응답 속도가 크게 향상되고, 더욱이 솔레노이드의 전제적인 크기와 무게를 줄일 수 있는 차량의 급발진 제어용 솔레노이드를 제공하고자 하는 것이다.The present invention has been made in order to improve the above problems, by installing a magnetic force reinforcing means at the rear end of the plunger, the magnetic force increased plunger significantly improves the response speed, moreover, the total size and weight of the solenoid To provide a solenoid for the rapid start control of the vehicle can be reduced.

상술한 목적을 달성하기 위한 본 발명은, 전류가 인가되면 자기장을 형성하는 코일이 권선되는 보빈(bobbin)과, 보빈의 일측으로 설치되는 바텀(bottom)과, 보빈의 중공 내부에 설치되어 상기 바텀과 반대 극성을 띄며 자기력에 의해서 이동되는 케이블(cable) 및 플런저(plunger)로 구성되는 차량의 급발진 제어용 솔레노이드에 있어서, 플런저의 후측 끝단부에 자기력보강수단을 설치함으로써, 플런저의 자기력 증가로 바텀과의 응답 속도를 향상시킨 차량의 급발진 제어용 솔레노이드를 제공한다. The present invention for achieving the above object is, the bobbin (bobbin) winding the coil to form a magnetic field when a current is applied, the bottom (bottom) is installed to one side of the bobbin, and installed inside the hollow of the bobbin bottom In a sudden start control solenoid of a vehicle composed of a cable and a plunger which is moved by magnetic force, having a polarity opposite to that of the plunger, the magnetic force reinforcing means is provided at the rear end of the plunger, thereby increasing the magnetic force of the plunger. Provides a rapid start control solenoid of the vehicle with improved response speed.

도 2는 본 발명에 따른 일실시예로 차량의 급발진 제어용 솔레노이드를 도시한 단면도이고, 도 3a, 3b, 3c는 본 발명에 따른 차량의 급발진 제어용 솔레노이드의 성능시험 선도이다.2 is a cross-sectional view showing a sudden start control solenoid of a vehicle according to an embodiment of the present invention, Figure 3a, 3b, 3c is a performance test diagram of the sudden start control solenoid of the vehicle according to the present invention.

차량의 급발진 제어용 솔레노이드(100)는, 전류가 인가되면 자기장을 형성하는 코일(112)이 권선되는 보빈(bobbin:110)이 개구된 중공부를 가지며 설치되고, 보빈(110)의 후측에 플레이트(120)가 삽입 설치되며, 보빈(110)의 전방측으로 브라켓(130)이 설치되고, 브라켓(130)의 내측으로 바텀(bottom:140)이 부시(142)와 같이 설치된다.The sudden start control solenoid 100 of the vehicle is provided with a hollow having an opening of a bobbin 110 in which a coil 112 for forming a magnetic field is wound when a current is applied, and a plate 120 at the rear side of the bobbin 110. ) Is inserted and installed, the bracket 130 is installed to the front side of the bobbin 110, the bottom (bottom: 140) is installed like the bush 142 to the inside of the bracket 130.

그리고 보빈(110)의 중공부에 일체로 연동되는 케이블(cable:160)과 플런저(plunger:150)가 설치되고, 플런저(150)의 후측으로는 충격 흡수용 댐퍼(170)가 스프링(172)과 같이 설치된다. A cable (160) and a plunger (150) are integrally interlocked with the hollow part of the bobbin 110, and a shock absorbing damper 170 is provided at the rear side of the plunger 150 for the spring 172. It is installed as follows.

여기서 본 발명의 특징에 따라서 플런저(150)의 자기력을 증대시킴으로써 바텀(140)으로부터 플런저(150)의 응답 속도를 향상시킬 수 있도록 플런저(150)의 후측 끝단부에 자기력보강수단을 설치하였다.The magnetic force reinforcing means is provided at the rear end of the plunger 150 to increase the response speed of the plunger 150 from the bottom 140 by increasing the magnetic force of the plunger 150 according to the features of the present invention.

도 2에 도시된 자기력보강수단의 일실시예는, 플런저(150)의 후측 끝단부에 링(152)이 삽입 고정 설치된다. 링(152)은 플런저(150)와 동일 재질이 바람직하며, 링(152)의 높이(H) 즉, 폭의 향상에 따라 힘도 증가하게 된다.In one embodiment of the magnetic force reinforcing means shown in Figure 2, the ring 152 is inserted and fixed to the rear end of the plunger 150. The ring 152 is preferably made of the same material as the plunger 150, and the force is also increased as the height H of the ring 152 is improved.

또한, 링(152)의 설치로 자기력이 증가된 플런저(150)는 그 길이와 폭의 감소가 가능하게 되었다.In addition, the installation of the ring 152 allows the plunger 150 whose magnetic force is increased to reduce its length and width.

이와 같이 본 발명에 따라 구성된 차량의 급발진 제어용 솔레노이드의 작용을 바람직한 실시예를 들어 설명하면 다음과 같다.Thus, the operation of the sudden start control solenoid of the vehicle configured according to the present invention will be described with reference to a preferred embodiment as follows.

솔레노이드(100)의 작동으로 먼저, 코일(112)에 전류가 인가되어 자기장이 발생하면, 자속이 보빈(110)의 브라켓(130)과 바텀(140)을 따라 흐르게 되고, 이에 반대 극성을 가지는 플런저(150)가 케이블(160)과 같이 댐퍼(170)의 스프링(172)을 압축시키면서 전진 이동된다. 따라서 전진 이동된 케이블(160)은 미도시된 레버를 고정시켜서 차량의 급발진을 방지하게 된다.In operation of the solenoid 100, first, when a current is applied to the coil 112 to generate a magnetic field, the magnetic flux flows along the bracket 130 and the bottom 140 of the bobbin 110, and the plunger has the opposite polarity. 150 is moved forward while compressing the spring 172 of the damper 170, such as cable 160. Therefore, the forwarded cable 160 is fixed to the lever not shown to prevent the sudden start of the vehicle.

이때, 플런저(150)의 후측 끝단부에 설치된 자기력보강수단인 링(152)은, 플런저가 앞으로 진행할수록 즉, 링(152)이 보빈(110)의 끝단에 근접할수록 자기력이 증가하고 링(152)의 높이(H) 그리고 단면적이 증가할수록 자기력이 증대되고, 이에 플런저(150)의 자기력 증대는 바텀(140)으로부터의 응답 속도를 빠르게 가져 갈 수 있다.At this time, the magnetic force reinforcing means installed in the rear end portion of the plunger 150, the magnetic force increases as the plunger moves forward, that is, the closer the ring 152 to the end of the bobbin 110, the ring 152 As the height (H) and the cross-sectional area of the) increases, the magnetic force increases, and thus, the magnetic force increase of the plunger 150 may bring a response speed from the bottom 140 faster.

그리고 코일(112)의 전류가 차단되면, 스프링(172)의 탄성력에 의해 댐퍼(170) 및 플런저(150)와 케이블(160)이 후퇴된다. 이 때 후퇴의 속도 역시 자기력에 비례하여 강한 스프링(172)에 의해 증가시킬 수 있다.When the current of the coil 112 is cut off, the damper 170, the plunger 150, and the cable 160 are retracted by the elastic force of the spring 172. At this time, the speed of retraction can also be increased by the strong spring 172 in proportion to the magnetic force.

한편, 도 3a, 3b, 3c는 링(152)의 높이를 증가시킴으로써 플런저(150)가 받는 힘이 증가되고 있음을 알 수 있는 성능 시험선도로서, 도 3a는 링(152)의 길이(L)를 1mm에서 4mm가지 각각 변화시켰을 때에 플런저(150)가 받는 힘의 크기를 나타냈으며, 이때, 링(152)의 높이(H)는 1mm로 고정하였다.3A, 3B, and 3C are performance test diagrams showing that the force received by the plunger 150 is increased by increasing the height of the ring 152, and FIG. 3A is a length L of the ring 152. When the change from 1mm to 4mm each showed the magnitude of the force received by the plunger 150, at this time, the height (H) of the ring 152 was fixed to 1mm.

그리고 도 3b에서는 링(152)의 길이(L)를 1mm로 하고, 도 3c에서는 링(152)의 길이(L)를 2mm로 하였으며, 각각에 대하여 링(152)의 높이(H)를 1mm에서 4mm로 변화시켰을 때의 힘의 결과를 나타낸 것이다.In FIG. 3B, the length L of the ring 152 is 1 mm, and the length L of the ring 152 is 2 mm in FIG. 3C, and the height H of the ring 152 is 1 mm for each. The result of the force when changed to 4mm is shown.

이처럼, 본 발명은 플런저(150)의 후측 끝단부에 자기력보강수단을 설치함으로써, 플런저(150)의 자기력 증가로 바텀과의 응답 속도를 빠르게 할 수 있다.As described above, the present invention provides a magnetic force reinforcing means at the rear end of the plunger 150, thereby increasing the magnetic force of the plunger 150 to increase the response speed with the bottom.

이상, 상기 내용은 본 발명의 바람직한 일실시 예를 단지 예시한 것으로 본 발명의 당업자는 본 발명의 요지를 변경시킴이 없이 본 발명에 대한 수정 및 변경 을 가할 수 있음을 인지해야 한다. In the above description, it should be understood that those skilled in the present invention can only make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

이상에서 설명한 바와 같이, 본 발명에 의한 차량의 급발진 제어용 솔레노이드는, 플런저의 후측 끝단부에 자기력보강수단을 설치함으로써, 자기력이 증가된 플런저는 바텀과의 응답 속도가 향상되고, 더욱이 솔레노이드의 전제적인 크기와 무게를 줄일 수 있게 됨으로써, 차량의 장착성이 뛰어나며, 원가가 절감되는 효과가 있다.As described above, the sudden start control solenoid of the vehicle according to the present invention is provided with a magnetic force reinforcing means at the rear end of the plunger, whereby the plunger with increased magnetic force improves the response speed with the bottom, and furthermore, the solenoid By being able to reduce the size and weight, the mounting of the vehicle is excellent, the cost is reduced.
