본 발명은 브레이크 컨트롤 시스템용 솔레노이드밸브에 관한 것으로,The present invention relates to a solenoid valve for a brake control system,

특히, 브레이크 컨트롤 시스템에 사용되는 솔레노이드밸브 중에서 NC(Normally Close)밸브의 슬리브와 시트하우징을 결합할 때 슬리브에 단차를 형성하여 링부재로 압입 고정할 수 있도록 하는 브레이크 컨트롤 시스템용 솔레노이드밸브에 관한 것이다.In particular, the present invention relates to a solenoid valve for a brake control system that allows a press-fitting and fixing to a ring member by forming a step in the sleeve when combining the sleeve of the NC (Normally Close) valve among the solenoid valves used in the brake control system. .

일반적으로 차량용 안티록 브레이크시스템은 바퀴 측으로 가해지는 제동압의 단속(斷續) 및 조절이 가능하도록 브레이크유압라인의 중도에 설치되는 것으로, 제어신호에 따라 유로를 개폐하는 다수의 솔레노이드밸브를 구비한다.In general, an anti-lock brake system for a vehicle is installed in the middle of a brake hydraulic line to control and control the braking pressure applied to the wheel side, and includes a plurality of solenoid valves that open and close the flow path according to a control signal. .

이러한 브레이크시스템용 솔레노이드밸브 중에서 NC밸브는 도 1에 도시된 바와 같이, 모듈레이터블록(13)의 밸브결합공(14)에 압입되어 설치되며, 유체의 흐름을 위한 입구(3)와 출구(4)를 갖는 중공의 시트하우징(1)을 구비한다.Among the brake system solenoid valves, the NC valve is press-fitted into the valve coupling hole 14 of the modulator block 13, as shown in FIG. 1, and has an inlet 3 and an outlet 4 for the flow of fluid. It is provided with a hollow seat housing (1) having.

상기 시트하우징(1)의 일단에는 그 내부에 설치되는 아마추어(5)가 진퇴할 수 있도록 원통형 슬리브(6)가 결합되며, 슬리브(6)의 개방된 단부에는 슬리브(6)의 개방된 부분을 폐쇄함과 동시에 아마추어(5)를 진퇴시키기 위한 마그네트코어(7)가 결합된다.A cylindrical sleeve 6 is coupled to one end of the seat housing 1 to allow the armature 5 installed therein to retreat, and an open portion of the sleeve 6 at an open end of the sleeve 6. At the same time as closing, the magnet core 7 for advancing the armature 5 is engaged.

또 아마추어(5)는 진퇴운동을 통해 밸브시트(8)의 오리피스(8a)를 개폐하도록 그 일단에 일체로 마련된 플런저(5a)가 시트하우징(1)의 중공부(2) 내에 설치된 밸브시트(8) 쪽으로 연장된다.In addition, the armature 5 has a valve seat provided in the hollow portion 2 of the seat housing 1 with a plunger 5a integrally provided at one end thereof so as to open and close the orifice 8a of the valve seat 8 through a forward and backward movement. 8) side.

상기 아마추어(5)와 마그네트코어(7) 사이에는 아마추어(5)가 평소 오리피스(8a)를 폐쇄한 상태를 유지하도록 아마추어(5)에 탄성 복원력을 부여하는 복원스프링(9)이 설치되고, 슬리브(6)와 마그네트코어(7)의 외측에는 아마추어(5)를 진퇴시키는 여자코일(10)이 설치된다.Between the armature 5 and the magnet core 7 is provided a restoring spring 9 for imparting elastic restoring force to the armature 5 so that the armature 5 keeps the orifice 8a normally closed. On the outside of the 6 and the magnet core 7, a female coil 10 for advancing and retracting the armature 5 is provided.

또한 상기와 같이 밸브시트(8)의 오리피스(8a)를 플런저(5a)로 개폐하는 아마추어(5)의 이동은 슬리브(6)의 상단에 용접부(6a)에 의해 고정된 마그네트코어(7)와 슬리브(6)의 하단에 용접부(6b)에 의해 고정된 시트하우징(1) 사이에서 이루어진다.Further, as described above, the movement of the armature 5 that opens and closes the orifice 8a of the valve seat 8 with the plunger 5a is performed by the magnet core 7 fixed by the welding portion 6a on the upper end of the sleeve 6. It is made between the seat housings 1 fixed by the weld 6b to the lower end of the sleeve 6.

이러한 구성의 NC밸브타입의 솔레노이드밸브는 아마추어(5)의 플런저(5a)가 밸브시트(8)의 오리피스(8a)를 항상 막고있는 상태에서 여자코일(10)에 전원이 인가될 때 마그네트코어(7)와 아마추어(5) 사이에 자기력이 생기고, 이 자기력에 의해 아마추어(5)가 복원스프링(9)을 압축하면서 마그네트코어(7) 쪽으로 이동하면 아마추어(5)의 이동거리만큼 플런저(5a)가 밸브시트(8)의 오리피스(8a)에서 떨어지게 되므로 밸브시트(8)의 오리피스(8a)를 열리게 된다.The NC valve type solenoid valve of this configuration has a magnet core (when power is applied to the excitation coil 10 in a state where the plunger 5a of the armature 5 always blocks the orifice 8a of the valve seat 8). A magnetic force is generated between the armature (7) and the armature (5). When the armature (5) moves toward the magnet core (7) while compressing the restoring spring (9) by this magnetic force, the plunger (5a) moves as much as the arming distance of the armature (5). Is dropped from the orifice 8a of the valve seat 8, so that the orifice 8a of the valve seat 8 is opened.

그리고 여자코일(10)에 인가되던 전원이 차단되면 자기력이 해제되며, 복원스프링(9)의 탄성에 의해 아마추어(5)가 원상태로 복귀되면서 오리피스(8a)가 닫힌다.When the power applied to the excitation coil 10 is cut off, the magnetic force is released, and the orifice 8a is closed as the armature 5 returns to its original state by the elasticity of the restoring spring 9.

상기와 같은 구성과 작용의 종래 솔레노이드밸브는 슬리브(6)와 마그네트코어(7)를 용접하여 용접부(6a)에 의해 조립되도록 함과 동시에 슬리브(6)와 시트하우징(1) 역시 용접을 하여 용접부(6b)에 의해 조립되도록 하는 구조이므로 슬리브 (6)와 마그네트코어(7) 및 시트하우징(1)의 재질선택이 까다롭다.Conventional solenoid valves having the above-described configuration and operation are welded to the sleeve 6 and the magnet core 7 to be assembled by the welded portion 6a, and the sleeve 6 and the seat housing 1 are also welded to the welded portion. Since the structure to be assembled by (6b), the material selection of the sleeve (6), the magnet core (7) and the seat housing (1) is difficult.

특히 마그네트코어(7)의 경우는 여자코일(10)에 의해 전자석이 될 수 있도록 해야하므로 재질선택의 여지가 없지만, 시트하우징(1)의 경우에는 어떠한 제약이 없음에도 불구하고 용접부(6b)에 의한 조립으로 인하여 용접성이 좋은 재질을 선택해야 하는 것이므로 제조 및 재료의 단가가 상승하게 되는 문제점이 있었다.Particularly, in the case of the magnet core 7, the magnet coil 10 must be made to be an electromagnet, so there is no choice of materials. However, in the case of the seat housing 1, the welding part 6b has no limitation. Due to the assembly by the good weldability to select a material, there was a problem that the cost of manufacturing and material rises.

상기와 같이 조립과정에서 슬리브(6)와 시트하우징(1)을 용접하게 되면 작업사이클 타임이 늘어나고, 조립조건의 세팅이 까다로워지는 문제점이 있었다.As described above, when the sleeve 6 and the seat housing 1 are welded in the assembling process, the work cycle time increases and the setting of the assembly condition is difficult.

따라서, 본 발명의 목적은 종래의 문제점을 해소하기 위한 것으로, 시트하우징의 결합부에 압입된 슬리브에 단차를 형성하여 그 단차의 외측으로 링부재가 압입되도록 함으로써 시트하우징은 용접성에 무관하게 폭넓은 재질 선택을 할 수 있고, 그로 인하여 재료비를 절감할 수 있으며, 소재 변형성에도 무관하게 시트하우징의 재질을 선택할 수 있게 될 뿐만 아니라, 슬리브와 시트하우징의 결합부위 상단에 형성된 단차와 그 아래의 확장된 직경으로 인하여 링부재의 압입이 필요한 부분에서만 이루어지고 압입된 결합상태로 안정시킬 수 있도록 한 브레이크 컨트롤 시스템용 솔레노이드밸브를 제공함에 있다.Accordingly, an object of the present invention is to solve the conventional problems, by forming a step in the sleeve pressed into the coupling portion of the seat housing to allow the ring member to be pressed into the outside of the step, the seat housing is wide regardless of weldability Material selection is possible, thereby reducing material costs, and the material of the seat housing can be selected irrespective of the material deformability, and the step formed on the upper part of the coupling portion of the sleeve and the seat housing and the extended portion thereunder The present invention provides a solenoid valve for a brake control system that is made only in a part requiring a press-in of a ring member due to its diameter, and stabilizes the press-fitted state.

이러한 본 발명의 목적은 다수 개의 솔레노이드밸브가 각각의 밸브결합공에 결합 구성되는 모듈레이터블록과, 상기 모듈레이터블록에 삽입되어 입구측으로 유입된 브레이크 오일을 필요에 따라 출구측으로 보내는 시트하우징과, 상기 시트하우징의 상측에 구비되고 복원스프링의 탄성력을 받을 수 있도록 하는 아마추어와, 상기 아마추어의 상측으로 구비되어 여자코일에 의해 자화되어 상기 아마추어를 당기는 마그네트코어와, 상기 시트하우징과 마그네트코어에 양단이 고정되어 상기 아마추어가 한정된 거리를 안정되게 직선 왕복운동할 수 있도록 하는 슬리브와, 상기 아마추어에 의해 오리피스가 개폐된 후 하측의 주밸브가 개폐되는 밸브시트를 포함하는 솔레노이드밸브에 있어서, 상기 슬리브의 하단에는 벤딩부를 형성하고, 그 슬리브의 하측에는 단차를 형성하여 단차 하측의 확대된 직경부위 슬리브가 시트하우징의 결합부 외측으로 압입되게 구성하며, 상기 단차 하측의 확대된 직경부위 슬리브 외측으로 링부재를 압입하여 구성된 것을 특징으로 한 솔레노이드밸브에 의해 달성될 수 있다.The object of the present invention is a modulator block comprising a plurality of solenoid valves coupled to each valve coupling hole, a seat housing for inserting the brake oil introduced into the modulator block to the inlet side to the outlet side, if necessary, and the seat housing An armature provided at an upper side of the arm and receiving an elastic force of a restoring spring, and a magnet core provided on an upper side of the armature and magnetized by a female coil to pull the armature, and both ends of the arm housing are fixed to the seat housing and the magnet core.

And the bottom of the sleeve In the solenoid valve, characterized in that the step formed by forming a stepped portion of the enlarged diameter sleeve in the lower side of the step portion is pressed into the outer side of the seat housing, and the ring member is pressed into the outside of the enlarged diameter portion sleeve of the stepped lower side Can be achieved by

이때 상기 링부재는 외주면 상단에 단턱을 형성하고 그 단턱에 모듈레이터블록을 소성 변형시켜서된 고정부재를 결합하여 구성됨을 특징으로 한다.At this time, the ring member is formed by combining the fixing member formed by forming a step on the upper end of the outer peripheral surface and plastic deformation of the modulator block on the step.
