Abstract

A solenoid valve for an anti-lock brake system is provided to reduce size of the raw material for processing of a valve housing, and also save the processing time. A solenoid valve(40) for an anti-lock brake system comprises a coil(42), a sleeve(45), an armature(47), a valve housing(50), and a modulator block(60). The coil forms an electric field as electricity is applied thereto. The sleeve having a cylinder form penetrates the center of the coil. The armature is inserted in one end of the sleeve, and moved up and down by the electric field generated at the coil. The valve housing receives the armature and is fixed to one end of the sleeve. The modulator block is connected with outer circumference of the valve housing. The valve housing, more specifically, has a mounting groove(50a) on the outer circumference thereof. After being pressed into a valve mounting hole formed on the modulator block, the valve housing is mounted to the valve mounting hole by a connection ring(54) having a projection part for connection with the mounting groove.

이하, 본 발명에 따른 하나의 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 2을 참조하면, 본 발명에 따른 안티록 브레이크용 솔레노이드밸브(40)는 유입포트와 토출포트가 형성되어 있는 모듈레이터블럭(60)의 밸브설치공에 삽입설치된다.2, the anti-lock brake solenoid valve 40 according to the present invention is inserted into the valve installation hole of the modulator block 60 is formed in the inlet port and the discharge port.

솔레노이드 밸브(40)의 상부는 보빈(41)에 권선되어 전류가 흐르면 전자기장을 형성하는 코일(42)과, 상기 코일(42)을 감싸며 일면이 개구된 중공의 원통형상으로 이루어진 코일 케이스(43)와, 코일케이스(43)의 개구면을 덮는 플러스링(44)를 구비한다.The upper part of the solenoid valve 40 is wound around the bobbin 41 to form an electromagnetic field when a current flows, and a coil case 43 formed of a hollow cylindrical shape surrounding one side of the coil 42 and openings. And a plus ring 44 covering the opening face of the coil case 43.

상기 코일케이스(43)의 중심부에는 양면이 개구된 원통형상의 슬리브(45)가 관통되며, 슬리브(45)의 상단 개구부에는 마그네트 코어(46)가 삽입 고정되고, 슬리브(45) 의 하단 개구부에는 아마추어(47)가 마그네트 코어(46)와 소정간격 이격되어 상하운동 가능하게 설치된다.A cylindrical sleeve 45 having both sides is penetrated through a central portion of the coil case 43, a magnet core 46 is inserted into and fixed to an upper end of the sleeve 45, and an armature is inserted into a lower end of the sleeve 45. The 47 is spaced apart from the magnet core 46 by a predetermined interval so as to be able to move up and down.

아마추어(47)의 하단에는 아마추어(47)보다 작은 직경을 가지는 봉상의 플런저(48)가 일체로 형성되어 아마추어(47)와 함께 연동되며, 플런저(48)의 끝단에는 구체(48a)가 구비된다.At the lower end of the armature 47, a rod-shaped plunger 48 having a diameter smaller than the armature 47 is integrally formed and interlocked with the armature 47, and the end of the plunger 48 is provided with a sphere 48a. .

상기 플런저(48)의 외주면에는 플런저(48)가 상하운동 가능하게 삽입되도록 중심부에 축방향의 관통공(49)이 형성된 밸브하우징(50)이 구비된다. 상기 밸브하우징(50)의 측면에는 오일유입로(51)가 형성되고, 상기 구체(48a)의 하단에는 오리피스가 천공된 밸브시트(52)가 밸브하우징(50)내의 밸브설치공에 안착된다.The outer circumferential surface of the plunger 48 is provided with a valve housing 50 in which a through hole 49 in the axial direction is formed at the center thereof so that the plunger 48 can be vertically inserted. An oil inflow passage 51 is formed at the side of the valve housing 50, and a valve seat 52 having an orifice perforated at the lower end of the sphere 48a is seated in the valve installation hole in the valve housing 50.

이와같이 상기 슬리브(45)와 밸브하우징(50)내에 부품이 조립된 상태에서 상기 슬리브(45)의 하단은 밸브하우징(50)의 상단부에 고정되며, 하나의 밸브조립체(53)가 완성되고, 상기 밸브조립체(53)에서 밸브하우징(50)은 모듈레이터블럭(60)의 밸브설치공에 압입되어 수용된다.As such, the lower end of the sleeve 45 is fixed to the upper end of the valve housing 50 in a state in which components are assembled in the sleeve 45 and the valve housing 50, and one valve assembly 53 is completed. In the valve assembly 53, the valve housing 50 is press-fitted into the valve installation hole of the modulator block 60 to be received.

상기 밸브설치공은 밸브조립체(53)가 삽입될 수 있도록 상측이 최대구경을 갖도록 가공되고 밸브하우징(50)이 삽입된 상태에서 모듈레이터블럭(60)에 고정되어 기밀이 유지되도록 밸브하우징(50)의 외주면과 밸브설치공의 내주면사이에 결합링(54)을 설치하여 체결한다.The valve installation hole is processed so that the upper side has a maximum diameter so that the valve assembly 53 can be inserted, and the valve housing 50 is fixed to the modulator block 60 while the valve housing 50 is inserted to maintain the airtightness. The coupling ring 54 is installed between the outer peripheral surface of the valve and the inner peripheral surface of the valve installation hole.

이를 위해 밸브하우징(50)의 외주면에는 중심부로 오목하게 굴곡된 설치홈(50a)이 구비되고 모듈레이터블럭(60)의 밸브설치공에는 단차부(61)가 형성된다.To this end, an outer circumferential surface of the valve housing 50 is provided with an installation groove 50a that is concavely curved toward the center thereof, and a step portion 61 is formed in the valve installation hole of the modulator block 60.

결합링(54)은 슬리브(45)에 코일케이스(43)가 슬리브에 결합되기 전에 설치하는 것으로, 결합링(54)은 밸브하우징(50)과 모듈레이터블럭(60)사이에서 체결력을 갖도록 외경과 내경이 각각 밸브설치공의 단차부(61) 내경과 설치홈(50a)의 외경과 최소한 동일하여야 한다.The coupling ring 54 is installed in the sleeve 45 before the coil case 43 is coupled to the sleeve. The coupling ring 54 has an outer diameter and a coupling force between the valve housing 50 and the modulator block 60. The inner diameter should be at least equal to the inner diameter of the step portion 61 of the valve installation hole and the outer diameter of the installation groove 50a, respectively.

그러나, 결합링(54)의 돌기부(54a) 내경은 슬리브(45)의 외경보다 작아 결합링(54)이 마그네트코어(46) 상단으로부터 삽입되어 슬리브(45)를 통과할 수 없으므로, 돌기부(54a)의 내경이 확대되도록 결합링(54)은 중심을 지나는 수평면으로부터 소정의 중심각을 갖도록 상측면이 내측 하방으로 경사진 상태에서 삽입된다.However, since the inner diameter of the protrusion 54a of the coupling ring 54 is smaller than the outer diameter of the sleeve 45, the protrusion 54a cannot be inserted from the upper end of the magnet core 46 and pass through the sleeve 45. The coupling ring 54 is inserted with the upper side inclined downward inwardly so as to have a predetermined center angle from the horizontal plane passing through the center so as to enlarge the inner diameter of.

도 3은 결합링이 경사진 상태에서 슬리브를 통과하고 있는 상태를 나타낸 것이다.3 shows a state in which the coupling ring passes through the sleeve in an inclined state.

결합링(54)이 슬리브(45)를 통과하여 결합링(54)의 내경부가 설치홈(50a)에 다다르면 도 4에서와 같이 고정부재(62)를 통해 결합링(54)의 상단을 아래로 가압하면 경사진 상태의 결합링(54)이 중심을 지나는 수평면상에서 펼쳐지게 되고, 결합링(54)의 설치가 끝나게 된다.When the coupling ring 54 passes through the sleeve 45 and the inner diameter of the coupling ring 54 reaches the installation groove 50a, the upper end of the coupling ring 54 is lowered through the fixing member 62 as shown in FIG. 4. When pressed, the inclined coupling ring 54 is unfolded on a horizontal plane passing through the center, and the installation of the coupling ring 54 is completed.

이 상태에서 밸브하우징(50)을 포함하는 밸브조립체(53)를 모듈레이터블럭(60)에 삽입 설치하고 도 2에서와 같이 결합링(54)의 상단부와 접하는 모듈레이터블럭(60)의 내경부 일부를 결합링(54)의 상단을 덮도록 가압하여 소성변형시키면 밸브하우징(50)의 모듈레이터블럭(60)에의 설치과정이 끝나게 되고, 코일케이스(43)를 슬리브(45)의 외주면에 결합시키면 솔레노이드밸브의 조립이 완결된다.In this state, the valve assembly 53 including the valve housing 50 is inserted into the modulator block 60 and a portion of the inner diameter of the modulator block 60 contacting the upper end of the coupling ring 54 as shown in FIG. When plastic deformation is performed by pressing the upper end of the coupling ring 54, the installation process of the valve housing 50 to the modulator block 60 is completed. When the coil case 43 is coupled to the outer circumferential surface of the sleeve 45, the solenoid valve Assembly is completed.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 안티록 브레이크 시스템용 솔레노이드 밸브는 중심각이 있는 별도의 결합링을 채용하여 결합링의 중심각을 해체하여 수평면에 일치시키는 과정에서 발생되는 내경 축소효과를 이용하여 밸브하우징의 기밀을 유지하도록 하여 밸브 하우징의 외주부의 최대 외경부를 축소하여 밸브하우징의 가공 제작을 위한 원소재의 크기 및 가공시간이 단축되는 효과가 있다. As described in detail above, the anti-lock brake system solenoid valve according to the present invention employs a separate coupling ring having a center angle to use the inner diameter reduction effect generated in the process of disassembling the center angle of the coupling ring to match the horizontal plane. By maintaining the airtightness of the valve housing has the effect of reducing the maximum outer diameter of the outer peripheral portion of the valve housing to reduce the size and processing time of the raw material for the processing of the valve housing.
