Description

안티 록 브레이크 장치Anti lock brake device

본 발명은 브레이크 장치에 관한 것으로서, 보다 상세하게는 자동차용 안티 록 브레이크 장치(Anti-Locking Brake System)에 관한 것이다.The present invention relates to a brake device, and more particularly to an anti-locking brake system for automobiles.

일반적으로, 자동차의 안티 록 브레이크 장치는 차량의 주행중 타이어가 록킹되면서 노면과 슬립이 발생되고, 이로 인해 정지 거리가 길어지는 것을 방지하기 위하여 개발되었다.In general, an anti-lock brake device of a vehicle has been developed to prevent roads and slips as the tire is locked while the vehicle is being driven, thereby prolonging the stopping distance.

즉, 상기한 안티 록브레이크 장치는 타이어를 록킹시키지 않고 노면과의 마찰력을 최대로 유지하도록 함으로써 정지 능력을 향상시키는 것이다.In other words, the above-described anti-lock brake device improves the stopping ability by maintaining the maximum frictional force with the road surface without locking the tire.

상기한 안티 록 브레이크 장치는 도3에 도시된 바와 같이 브레이크 밸브(50)와, 상기한 브레이크 밸브(50)에 연결되어 있는 리저버 탱크(51)와, 상기한 브레이크 밸브(50)에 릴레이 밸브(52)를 개재한 상태로 연결된 2개의 더블 체크 밸브(53)와, 상기한 더블 체크 밸브(53)에 연통됨과 아울러 리저버 탱크(51)에 연결된 스핀 방지 밸브(54)와, 상기한 스핀 방지 밸브(54)에 연결된 ECU(55) 및 휠 센서(56)와, 상기한 더블 체크 밸브(53)에 각각 연결된 각 차륜의 압력 밸브(57) 및 에어 챔버(58)로 구성되어 있다.As shown in FIG. 3, the anti-lock brake device includes a brake valve 50, a reservoir tank 51 connected to the brake valve 50, and a relay valve to the brake valve 50. Two double check valves 53 connected via 52, the spin check valve 54 connected to the reservoir tank 51 and the spin check valve 53 connected to the reservoir tank 51, and the spin check valve described above. ECU 55 and wheel sensor 56 connected to 54, and pressure valve 57 and air chamber 58 of each wheel connected to said double check valve 53, respectively.

상기한 브레이크 장치는 운전자가 브레이크 밸브(50)를 동작시키게 되면 릴레이 밸브(52)와 더블 체크 밸브(53)를 통해 공압이 에어 챔버(58)에 전달되면서 브레이크를 동작시키게 되는 것이다.When the driver operates the brake valve 50, the brake device operates the brake while the pneumatic pressure is transmitted to the air chamber 58 through the relay valve 52 and the double check valve 53.

여기서, 상기한 각 차륜중 하나의 휠이 스핀을 일으키게 되면 횔 센서(56)에 의해 ECU(55)가 이를 체크하게 됨과 아울러 스핀 방지 밸브(54)를 동작시키게 된다.In this case, when one wheel of each of the wheels causes the spin, the ECU 55 checks this by the 횔 sensor 56 and operates the spin prevention valve 54.

스핀 방지 밸브(54)가 동작되면 리저버 탱크(51)로부터의 공압이 스핀되는 휠에 공급됨으로써 스핀을 감쇄시키게 되는 것이다.When the spin prevention valve 54 is operated, the pneumatic pressure from the reservoir tank 51 is supplied to the wheel to spin, thereby reducing the spin.

상기한 스핀 방지 밸브(54)는 도4에 도시된 바와 같이 입구(59) 및 제 1, 2출구(60, 61)가 형성된 밸브 본체(62)와, 상기한 밸브 본체(62)에 승강 가능하도록 설치됨과 아울러 제 1, 2출구(60, 61)를 간헐 제한하도록 설치된 제 1, 2솔레노이드 밸브(63, 64)로 구성되어 있다.As shown in FIG. 4, the spin prevention valve 54 can be lifted up and down the valve body 62 having the inlet 59 and the first and second outlets 60 and 61, and the valve body 62. The first and second solenoid valves 63 and 64 are installed to intermittently limit the first and second outlets 60 and 61.

즉, 입구(59)로부터 공압이 인가되면 휠이 스핀되는 위치인 제1 또는 2출구(60, 61)측의 솔레노이드 밸브(63, 64)를 동작시킴으로써 휠 스핀을 차단하게 되는 것이다.That is, when pneumatic pressure is applied from the inlet 59, the wheel spin is blocked by operating the solenoid valves 63 and 64 on the first or second outlets 60 and 61, which are the positions at which the wheels are spun.

그러나, 상기한 바와 같은 스핀 방지 밸브는 구성이 복잡하여 제조가 어려울 뿐만 아니라 이를 통해 횔 스핀을 제어하기 위하여 각각의 라인으로 구성된 2개의 더블 체크 밸브를 사용하게 됨으로써 제작비가 많이 소요되는 문제점이 있다.However, the spin prevention valve as described above is not only difficult to manufacture due to the complicated configuration, but also has a problem in that the production cost is high due to the use of two double check valves each configured to control the spin.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 구성이 단순화됨과 아울러 하나의 더블 체크 밸브만을 사용하여 스핀 방지 회로를 구성할 수 있도록 구성된 안티 록 브레이크 장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, to provide an anti-lock brake device configured to simplify the configuration and to configure a spin prevention circuit using only one double check valve.

상기한 목적을 실현하기 의하여 본 발명은 브레이크 밸브와, 상기한 브레이크 밸브에 연결된 릴레이 밸브와, 상기한 릴레이 밸브로부터의 공압을 제어하도록 ECU에 연결되어 있고 에어 챔버에 연결되어 있는 압력 밸브를 구비한 안티 록 브레이크 장치에 있어서, 상기한 릴레이 밸브에 연결됨과 아울러 2개의 압력 밸브에 연결된 하나의 더블 체크 밸브와, 상기한 더블 체크 밸브에 연결됨과 아울러 리저버 탱크에 연결된 스핀 방지 밸브를 포함함을 특징으로 한다.In order to achieve the above object, the present invention provides a brake valve, a relay valve connected to the brake valve, and a pressure valve connected to an ECU and connected to an air chamber to control pneumatic pressure from the relay valve. An anti-lock brake device comprising: a double check valve connected to the relay valve as well as two pressure valves, and a spin prevention valve connected to the reservoir tank and connected to the double check valve. do.

도1과 도2는 본 발명에 따른 안티 록 브레이크 장치의 스핀 방지 밸브 설치 상태를 도시한 개략도와 밸브 단면도로서, 릴레이 밸브(52)와 스핀 방지 밸브(1)가 하나의 더블 체크 밸브(53)를 개재한 상태로 연결되어 있고, 상기한 더블 체크 밸브(53)에 2개의 압력 밸브(57)가 안결되어 공압의 온, 오프를 제어하게 되어 있다.1 and 2 are schematic and sectional views showing the anti-spin valve installation state of the anti-lock brake device according to the present invention, wherein the relay valve 52 and the anti-spin valve 1 have one double check valve 53. The two pressure valves 57 are secured to the above double check valve 53 to control on / off of the pneumatic pressure.

즉, 종래 2개의 출구(60, 61)를 갖는 스핀 방지 밸브(54)에 2개의 더블 체크 밸브(53)를 연결하여 상기한 스핀 방지 밸브(54)로 공압을 제어하는 것에 비해 하나의 더블 체크 밸브(53)만을 사용함과 아울러 기존 부품인 압력 밸브(57)로 공압을 제어하게 됨으로써 구성이 단순화되는 것이다.That is, the double check valve 53 is connected to the spin prevention valve 54 having the two outlets 60 and 61 in the related art, so that the double check valve 53 controls the air pressure with the spin prevention valve 54. In addition to using only the valve 53, by controlling the pneumatic pressure with the existing pressure valve 57, the configuration is simplified.

상기한 스핀 방지 밸브(1)는 도2에 도시된 바와 같이 하나의 입구(2)와 하나의 출구(3)를 갖는 본체(4)와 상기한 본체(4)에 설치되어 출구(3)를 제어하게 되는 솔레노이드 밸브(5)로 구성되어 있다.The spin preventing valve 1 is installed in the main body 4 and the main body 4 having one inlet 2 and one outlet 3 as shown in FIG. It consists of the solenoid valve 5 to control.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 운전자가 주행중 브레이크 밸브(50)를 동작시키게 되면 릴레이 밸브(52)를 통해 공압이 더블 체크 밸브(53)로 인가되고, 상기한 공압은 다시 압력 밸브(57)로 인가된다.As described above, when the driver operates the brake valve 50 while driving, pneumatic pressure is applied to the double check valve 53 through the relay valve 52, and the pneumatic pressure is again a pressure valve. Is applied to (57).

압력 밸브(57)로 인가된 공압은 에어 챔버(58)에 공급됨으로써 각각의 휠에 설치된 브레이크를 동작시켜 정지시키게 된다.Pneumatic pressure applied to the pressure valve 57 is supplied to the air chamber 58 to stop the brakes provided on each wheel by operating.

여기서, 상기한 주행중 일측 타이어 예를 들면, 좌측의 횔이 스핀을 일으키게 되면 휠 센서(56)에 의해 ECU(55)가 이를 감지하게 되고, 상기한 ECU(55)가 스핀 방지 밸브(1)를 동작시키게 된다.Here, when the tire on one side, for example, the wheel on the left side causes the spin, the ECU 55 detects this by the wheel sensor 56, and the ECU 55 opens the spin prevention valve 1. It will work.

스핀 방지 밸브(1)가 동작되면 솔레노이드 밸브(5)가 상승하게 됨으로써 출구(3)가 개방되어 별도로 리저버 탱크(51)에 저장되어 있는 공압이 더블 체크 밸브(53)로 인가된다.When the spin prevention valve 1 is operated, the solenoid valve 5 is raised to open the outlet 3 so that the pneumatic pressure stored in the reservoir tank 51 is applied to the double check valve 53.

더블 체크 밸브(53)로 인가된 공압은 2개의 압력 밸브(57)에 도달되는 바, 상기한 압력 밸브(57)중 좌측의 압력 밸브(57)를 ECU(55)가 동작시켜 개방되어 있는 상태가 됨으로써 좌측의 휠이 제동되면서 스핀을 감쇄시키게 되는 것이다.The pneumatic pressure applied to the double check valve 53 reaches the two pressure valves 57, and the ECU 55 operates the pressure valve 57 on the left side of the pressure valve 57 to open. This will damp the spin while the wheel on the left brakes.

즉, 종래에는 스핀 방지 밸브(54) 자체가 좌우측의 선택 역할을 하지만 본 발명에서는 기존 설치 부품인 압력 밸브(57)에 의해 좌우측을 선택하게 됨으로써 스핀 방지 밸브(1)의 구성을 단순화시킬 수 있게 되는 것이다.That is, in the related art, the spin prevention valve 54 itself plays a role of selecting left and right, but in the present invention, the left and right sides are selected by the pressure valve 57 which is an existing installation part, so that the configuration of the spin prevention valve 1 can be simplified. Will be.

물론, 상기한 스핀 방지 밸브(1)에 하나의 출구(3)만 존재하기 때문에 이와 연결되는 더블 체크 밸브(53)도 하나만 필요하게 되어 전체적으로 브레이크 라인의 구성이 단순화된다.Of course, since only one outlet 3 exists in the above-described spin prevention valve 1, only one double check valve 53 connected thereto is required, thereby simplifying the overall configuration of the brake line.

이상과 같이 본 발명은 스핀 방지 밸브의 구성을 단순화함과 아울러 더블 체크 밸브를 하나만 사용하게 됨으로써 브레이크 라인의 구성이 단순화되고, 제작이 용이하게 되는 잇점이 있는 것이다.As described above, the present invention has the advantage of simplifying the configuration of the spin prevention valve and using only one double check valve, thereby simplifying the configuration of the brake line and facilitating manufacturing.
