Description

전자제어식 브레이크 시스템을 위한 밸브{Valve for electronic control brake system}Valve for electronic control brake system

본 발명은 전자제어식 브레이크 시스템을 위한 밸브에 관한 것으로, 더욱 상세하게는 종래보다 용이하게 제조할 수 있고 제조비용도 줄일 수 있는 전자제어식 브레이크 시스템을 위한 밸브에 관한 것이다.The present invention relates to a valve for an electronically controlled brake system, and more particularly to a valve for an electronically controlled brake system that can be manufactured more easily than before and can reduce manufacturing costs.

일반적으로, 전자제어식 브레이크 시스템은 차량의 제동, 급발진, 또는 급가속시 발생할 수 있는 휠의 슬립현상을 효율적으로 방지하기 위한 것으로, 마스터 실린더에서 휠 실린더 측으로 전달되는 제동 유압을 제어하는 다수의 밸브 즉, 솔레노이드밸브와, 휠 실린더로부터 빠져나온 오일을 일시 저장하기 위한 어큐뮬레이터와, 휠 실린더에서 빠져나온 오일을 마스터 실린더 측으로 회수시키기 위한 오일펌프와, 솔레노이드밸브와 오일펌프의 구동을 제어하기 위한 전자제어유닛(ECU)을 포함한다. In general, the electronically controlled brake system effectively prevents wheel slippage that may occur during vehicle braking, rapid start, or rapid acceleration, and includes a plurality of valves for controlling the braking hydraulic pressure transmitted from the master cylinder to the wheel cylinder. , Solenoid valve, accumulator for temporarily storing oil from wheel cylinder, oil pump for recovering oil from wheel cylinder to master cylinder, electronic control unit for controlling operation of solenoid valve and oil pump (ECU).

도 1은 종래의 전자제어식 브레이크 시스템을 위한 밸브를 나타낸 것으로, 밸브는 도시된 바와 같이 브레이크 시스템의 유로들이 형성된 모듈레이터블록(10)의 보어(11)에 압입되어 설치되는 구조로 설치되며, 유체의 흐름을 위한 유입 구(20a)와 유출구(20b)를 갖는 중공의 밸브하우징(20)을 구비한다.Figure 1 shows a valve for a conventional electronically controlled brake system, the valve is installed in a structure that is press-fitted into the bore 11 of the modulator block 10, the flow path of the brake system is formed as shown, A hollow valve housing 20 having an inlet 20a and an outlet 20b for flow.

여기서, 밸브하우징(20)의 일단에는 그 내부에 설치되는 아마츄어(30)가 진퇴할 수 있도록 원통형 슬리브(50)가 결합되고, 슬리브(50)의 개방된 단부에는 이 슬리브(50)의 개방된 부분을 폐쇄하며 아마츄어(30)를 진퇴시키기 위한 밸브 코어(40)가 결합된다.Here, the cylindrical sleeve 50 is coupled to one end of the valve housing 20 so that the armature 30 installed therein may retreat, and the open end of the sleeve 50 may be opened. A valve core 40 is engaged to close the part and to retract the armature 30.

이때, 슬리브(50)의 외측에는 코일(미도시)이 감싸는 구조로 마련되어 전압이 인가됨에 따라 전자기적 상호작용에 의해 밸브 코어(40)가 진퇴하면서 아마츄어(30)도 진퇴하게 된다. 또, 아마츄어(30)의 하부 끝단에는 구체(35)가 마련되며, 이 구체(35)의 하측 방향에는 밸브시트(60)가 설치된다. At this time, the outside of the sleeve 50 is provided with a structure wrapped around a coil (not shown) as the voltage is applied to the valve core 40 by the electromagnetic interaction, the amateur 30 is also advanced. In addition, the lower end of the armature 30 is provided with a sphere 35, the valve seat 60 is provided in the lower direction of the sphere (35).

한편, 상술한 밸브시트(60)에는 길이방향으로 유로(60a)가 형성되는데, 이 유로(60a)의 주변에는 도시된 바와 같이 밸브하우징(20)에 또 다른 유로 즉 유출구(20b)가 형성되어 있다. 여기서, 밸브하우징(20)에 형성된 유로(20b)는 이 밸브하우징(20)의 반경방향으로 구멍을 형성함으로써 만들어진다. Meanwhile, a flow path 60a is formed in the valve seat 60 in the longitudinal direction, and another flow path 20b is formed in the valve housing 20 as shown in the periphery of the flow path 60a. have. Here, the flow path 20b formed in the valve housing 20 is made by forming a hole in the radial direction of the valve housing 20.

하지만, 밸브하우징(20)에 반경방향으로 구멍을 형성하기 위해서는 단조가공에 의해 주로 이루어지는데, 상기와 같은 단조가공은 통상적인 절삭가공에 비해 어려운 문제점이 있다. 또, 단조가공에 의해 밸브하우징(20)에 구멍을 형성하더라도 추가적인 절삭가공이 필요하여 단조가공만으로 밸브하우징(20)을 제작할 수 없다. 또, 밸브하우징(20)에 압입되어 설치된 밸브시트(60)의 유로측에 구멍을 형성해야 하기 때문에 구멍 형성을 위한 공간만큼 밸브의 길이가 길어지는 문제점이 있다.However, in order to form a hole in the valve housing 20 in the radial direction is mainly made by forging, such a forging is difficult compared to the conventional cutting. In addition, even if a hole is formed in the valve housing 20 by forging, additional cutting is required, and thus, the valve housing 20 cannot be manufactured by only forging. In addition, since the hole must be formed in the flow path side of the valve seat 60 press-fitted into the valve housing 20, the length of the valve is long as much as the space for forming the hole.

따라서, 본 발명은 이와 같은 문제점을 감안한 것으로서, 본 발명의 목적은 종래의 밸브와 다른 유로 구조를 통하여 밸브하우징의 형상을 단순화하고 적은 비용으로 제작할 수 있는 전자제어식 브레이크 시스템을 위한 밸브를 제공하는데 있다.Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a valve for an electronically controlled brake system that can simplify the shape of the valve housing and manufacture the valve housing through a flow path structure different from that of a conventional valve. .

In this case, the sleeve 180 is press-opened and fixed to an outer surface of the valve housing 120, and the sleeve 180 may be fixed to the valve housing 120 by welding or the like.

아마츄어(170)는 진퇴동작에 의해 플런저(160) 상부를 가압하도록 슬리브(180) 내에 진퇴 가능하게 설치된다. 여기서, 아마츄어(170)는 자성체로 이루어지며, 아마츄어(170)의 외면 일측에는 상하로 오일이 유통할 수 있도록 오일유로(171)가 형성된다.The armature 170 is retractably installed in the sleeve 180 to press the upper portion of the plunger 160 by the retraction operation. Here, the amateur 170 is made of a magnetic material, the oil flow path 171 is formed on one side of the outer surface of the amateur 170 so that the oil can flow up and down.

또한, 아마츄어(170) 주위의 슬리브(180) 내면에는 상호 소정 간격 이격된 원통형의 자성체(181)가 각각 설치되며, 이때의 각 자성체(181)는 아마츄어(170)의 이동방향으로 상호 이격된다. 그리고, 도면에 도시되지는 않았지만 슬리브(180)의 외면에는 코일조립체(미도시)가 마련되어 아마츄어(170)를 진퇴시키는 역할을 수행한다.In addition, cylindrical magnetic bodies 181 spaced apart from each other by predetermined intervals are installed on the inner surface of the sleeve 180 around the armature 170, and the magnetic bodies 181 at this time are spaced apart from each other in the moving direction of the armature 170. Although not shown in the drawings, a coil assembly (not shown) is provided on an outer surface of the sleeve 180 to advance and retract the amateur 170.

따라서, 본 발명의 실시예에서는 밸브시트의 중심에 형성된 내측유로와 그 외면에 홈형상으로 형성된 외측유로에 의해 유입구를 통해 유입된 유체가 유출구로 흐르므로 밸브하우징에 별도의 유로를 형성하는 종래와는 달리 밸브하우징의 길이 축소가 가능하며 밸브하우징을 단순화할 수 있다. 이에 따라 밸브하우징의 제작 시 단조가공할 수 있어 비용이 절감되는 효과가 있다.Therefore, in the exemplary embodiment of the present invention, since the fluid flowing through the inlet flows through the inlet by the inner flow path formed in the center of the valve seat and the outer flow path formed in the groove shape on the outer surface thereof, the separate flow path is formed in the valve housing. Alternatively, the length of the valve housing can be reduced and the valve housing can be simplified. As a result, forging may be performed when the valve housing is manufactured, thereby reducing the cost.
