Description

자동차의 브레이크 공기탱크 구조Brake air tank structure of car

본 발명은 자동차의 브레이크 공기탱크에 관한 것으로, 특히 전륜과 후륜으로 가는 브레이크 라인에 동일한 압력의 공기를 공급시킬 수 있도록 된 자동차의 브레이크 공기탱크 구조에 관한 것이다.The present invention relates to a brake air tank of a motor vehicle, and more particularly, to a brake air tank structure of a motor vehicle capable of supplying air of equal pressure to a brake line going to a front wheel and a rear wheel.

일반적으로, 대형자동차의 브레이크장치는 주행중인 자동차의 움직임을 정지 시키거나 차속을 감속시키기 위한 것으로, 이러한 브레이크장치에는 주행중 주로 운전자의 발동작에 의해 작동되는 주브레이크(일명 풋브레이크)와, 차량을 노면상에 주차시키기 위해 손동작에 의해 작동되는 주차브레이크(일명 핸드브레이크)로 대별된다.In general, the brake device of a large vehicle is to stop the movement of the driving car or to reduce the speed of the vehicle, and such brake device includes a main brake (also called a foot brake) mainly operated by the driver's foot movement during driving and a road surface. They are roughly classified as parking brakes (aka hand brakes) which are activated by hand gestures to park on the road.

여기서, 브레이크장치에는 로드와 와이어를 사용하는 기계식과 유압식이 있는데, 통상적으로 상기 주브레이크는 유압식을 이용하게 되며, 상기 주차브레이크는 기계식을 이용하게 된다.Here, the brake device is a mechanical and hydraulic using a rod and a wire, the main brake is a hydraulic using a conventional, the parking brake is to use a mechanical.

한편, 주브레이크는 유압식 이외에 압축공기를 이용하는 공기식 브레이크가 이용되고 있다.On the other hand, the main brake is a pneumatic brake using compressed air in addition to hydraulic.

여기서, 공기브레이크에는 엔진의 구동에 의해서 발생되는 흡입공기를 일정한 압력으로 압축하여 공급시킬 수 있도록 된 공기탱크가 연결설치되어 있는데, 이러한 공기탱크는 압축공기속에 함유된 수분을 제거하여 주는 탈수탱크와, 전륜으로 공기를 공급하여 주는 앞탱크 및, 후륜으로 공기를 공급하여 주는 뒤탱크로 구성되어 있다.Here, the air brake is connected to the air tank that can be supplied by supplying compressed air in a constant pressure generated by the drive of the engine, such an air tank and the dehydration tank to remove the moisture contained in the compressed air It consists of a front tank that supplies air to the front wheels and a rear tank that supplies air to the rear wheels.

즉, 상기한 기능을 수행할 수 있도록 된 종래의 공기탱크는 제1도의 구성도에 개략적으로 도시된 바와 같이, 엔진에서 공급되는 공기를 일정한 압력으로 압축시키는 압축기(100)와, 이 압축기(100)를 통해 압축되어진 공기의 내부에 함유된 수분을 제거시키는 탈수탱크(110), 전륜의 좌우측 브레이크장치로 공급되는 공기가 저장된 제1,2앞탱크(120,130), 후륜의 좌우측 브레이크장치로 공급되는 공기가 저장된 제1,2뒤탱크(140,150) 및, 주차브레이크장치로 공급되는 공기공급파이프(160)로 구성되어 있다.That is, the conventional air tank, which is capable of performing the above functions, has a compressor 100 for compressing air supplied from an engine to a constant pressure, as shown in the configuration diagram of FIG. 1, and the compressor 100. Dehydration tank 110 to remove the moisture contained in the compressed air through the), the first and second tanks 120 and 130 stored in the air supplied to the left and right brake device of the front wheel, supplied to the left and right brake device of the rear wheel The first and second rear tanks 140 and 150 in which air is stored, and the air supply pipe 160 is supplied to the parking brake device.

또한, 압축기(100)와 탈수탱크(110)의 사이에는 압축된 공기의 압력이 규정치 이상으로 되면 외부로 배출시키는 안전밸브(101)가 장착되며, 제1,2앞/뒤탱크(120,130,140,150)의 입구에는 압축공기가 역류되는 것을 방지시키는 첵밸브(121,131,141,151)가 각각 장착된 구조로 되어 있다.In addition, between the compressor 100 and the dehydration tank 110 is installed a safety valve 101 for discharging to the outside when the pressure of the compressed air is more than the prescribed value, the first and second front / rear tanks (120, 130, 140, 150) At the inlet, the check valves 121, 131, 141, and 151 are mounted to prevent compressed air from flowing back.

따라서, 상기 압축기(100)에서 압축된 공기는 상기 탈수탱크(110)를 거쳐 상기 앞뒤탱크(120,130,140,150)로 유입되며, 이 앞뒤탱크내의 공기는 각각의 브레이크 라인으로 공급되는 것이다. 물론, 압축기(100)는 앞뒤탱크(120,130,140,150)에 일정한 분량의 공기가 충진되면 작동이 멈추게 되고, 공기의 분량이 부족하면 재작동하게 되어 것이다.Therefore, the compressed air in the compressor 100 is introduced into the front and rear tanks 120, 130, 140 and 150 via the dehydration tank 110, the air in the front and rear tanks are supplied to the respective brake lines. Of course, the compressor 100 is stopped when a certain amount of air is filled in the front and rear tanks (120, 130, 140, 150), it will be restarted if the amount of air is insufficient.

그런데, 탈수탱크(110)에서 수분이 제거된 압축공기가, 먼저 제1앞/뒤탱크(120,140)로 공급된 후에, 제2앞/뒤탱크(130)로 나중에 공급되게 되므로써, 제1,2앞/뒤탱크(120,130,140,150)내로 동일한 압력 또는 동일한 분량의 압축공기를 유지시키는 것이 불가능하므로 예컨대, 브레이크를 작동시키는 경우에 차량이 한쪽방향으로 쏠리게 된다는 문제점이 있었다.However, since the compressed air from which the water is removed from the dehydration tank 110 is first supplied to the first front / rear tanks 120 and 140 and later supplied to the second front / rear tanks 130, the first and second Since it is impossible to maintain the same pressure or the same amount of compressed air into the front / rear tanks 120, 130, 140, and 150, there is a problem that the vehicle is oriented in one direction when the brake is operated.

또한, 제1,2앞/뒤탱크(120,130,140,150)에 공기가 부족한 경우 상기 압축기(100)에 의하여 공기가 공급되므로, 공기의 충진시간이 소요된다는 또다른 문제점이 있었다.In addition, when air is insufficient in the first and second front / rear tanks 120, 130, 140, and 150, air is supplied by the compressor 100, and thus there is another problem in that air filling time is required.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 전륜과 후륜으로 가는 브레이크 라인에 동일한 압력의 공기를 공급시킬 수 있도록 된 자동차의 브레이크 공기탱크 구조를 제공하는데에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, the object of the present invention is to provide a brake air tank structure of a vehicle that can supply the air of the same pressure to the brake line going to the front wheel and the rear wheel. have.

물론, 압력균일장치(80)의 내부는 연통된 상태이므로, 이 압력균일장치(80)에서 균일한 압력으로 유지된 압축공기는 제1,2앞뒤탱크(30,40,50,60)에 균일한 상태로 공급되는 것이다.Of course, since the inside of the pressure uniform device 80 is in a communicating state, the compressed air maintained at a uniform pressure in the pressure uniform device 80 is uniform to the first and second front and rear tanks 30, 40, 50, and 60. It is supplied in a state.

또한, 수용홈(81)의 후단부에 장착된 상기 배출구(84)는 피스톤의 작용을 원활하게 유지시키기 위한 것으로, 수용홈(81)의 내부에 충진된 공기를 외부로 배출 시키게 되는 것이다.In addition, the discharge port 84 mounted to the rear end of the receiving groove 81 is for smoothly maintaining the action of the piston, it is to discharge the air filled in the interior of the receiving groove 81 to the outside.

이상 설명한 바와 같이 본 발명에 따른 자동차용 브레이크 공기탱크의 구조에 의하면, 제1,2앞뒤탱크의 내부에 동일한 압력 또는 동일한 분량의 압축공기가 유지되므로써, 브레이크를 작동시 한쪽방향으로 쏠림이 방지될 뿐만 아니라 공기가 일정하게 브레이크라인으로 공급되므로써, 브레이크의 답력이 향상되는 효과가 있는 것이다.As described above, according to the structure of the automobile brake air tank according to the present invention, the same pressure or the same amount of compressed air is maintained inside the first and second front and rear tanks, thereby preventing the brake from being pulled in one direction. In addition, since the air is constantly supplied to the brake line, the pedal effort of the brake is improved.
