자동차의 타이어 공기압 조절장치{an air pressure control device of tire for a vehicle}An air pressure control device of tire for a vehicle

본 발명은 자동차의 타이어 공기압 조절장치에 관한 것으로, 특히 노면의 상태와 차량의 적재상태에 따라 타이어의 공기압을 조절하여 보다 안전하고 효율적인 주행을 할 수 있도록 된 자동차의 타이어 공기압 조절장치에 관한 것이다.The present invention relates to a tire inflation pressure regulating device of an automobile, and more particularly, to a tire inflation pressure regulating device of a vehicle that enables safer and more efficient driving by adjusting tire pressure in accordance with a road surface and a loading state of a vehicle.

일반적으로 자동차의 타이어 압력은 주행 및 타이어 자체의 수명에 영향을 미치는바, 공기압이 너무 높으면 승차감이 떨어지고, 반대로 너무 낮으면 동력손실이 클 뿐만 아니라 타이어의 측부가 마모되는 이상마모현상이 발생하게 된다.In general, the tire pressure of the car affects the driving and the life of the tire itself. If the air pressure is too high, the ride quality is decreased. On the contrary, if the air pressure is too low, the wear loss is excessive as well as the power loss is great. .

따라서, 상기와 같은 점을 고려하여 타이어는 적정압력으로 공기충전되어 있는데, 승용차의 경우 표준공기압은 약 1.7∼2.1kg/cm2이고 트럭 및 버스의 경우에는 약 4.2kg/cm2이 되도록 조절되어 있다.Thus, there considering that as the tire is filled with air pressure titration, in the case of a standard passenger car air pressure is about 1.7~2.1kg / cm 2 in the case of truck and bus is controlled to be about 4.2kg / cm 2 have.

한편, 자동차는 항상 포장이 잘된 도로만을 주행하는 것이 아니고, 경우에 따라서는 비포장도로 또는 야지(野地)의 자갈길, 모래길을 달리기도 하며, 비가 와서 노면에 수막이 형성되어 있을 경우도 있고, 또한 차량 자체의 상태가 짐을 적재한 상태일 수도 있고 아닐 수 도 있는데, 이러한 각각의 상황에 따라 타이어의 적정공기압은 모두 다를 수 밖에 없다.On the other hand, automobiles do not always drive only well-paved roads, and in some cases, they run on unpaved roads, gravel roads and sandy roads on unpaved roads. The condition of the vehicle itself may or may not be loaded, and the proper air pressure of the tires may be different depending on each of these situations.

그럼에도 불구하고 운전자들은 포장도로, 비포장도로, 눈길,빗길, 모래길 등 노면상태와는 관계없이 평상시 주행처럼 똑같은 타이어 공기압으로 주행을 할 수 밖에 없으므로 주행중에 동력손실이 크고, 연료소비량이 증대되는 문제점이 있었다.Nevertheless, drivers are forced to run with the same tire inflation pressure as normal driving regardless of road conditions such as pavement, dirt road, snow road, rain road, sand road, etc. There was this.

한편, 기존에는 웅덩이, 모래사장 등의 악로에서 차동장치나 인터록장치등을 동작시켜 비상상황에 대처하였으나, 이들은 사용후 바로 해제시켜야 하며 평로로 접어든 후에도 계속 작동시에는 사고발생의 위험이 있다.On the other hand, in the past, a differential device or an interlock device was operated in a muddy furnace such as a puddle or a sandy beach to cope with an emergency situation, but these should be released immediately after use, and there is a risk of an accident when it continues to operate even after entering a flat road.

이에 본 발명은 상기와 같은 문제점들을 해결하기 위하여 발명된 것으로, 노면상태와 화물 적재상태에 따라 적절히 타이어의 공기압을 조절할 수 있게 됨으로써 안전하면서도 동력손실이 적은 효율적인 운행을 할 수 있음은 물론, 타이어의 이상마모를 방지하여 수명을 연장시킬 수 있도록 된 자동차의 타이어 공기압 조절장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, it is possible to properly adjust the air pressure of the tire in accordance with the road surface and load state, it is possible to safely and efficiently run less power loss, of course, It is an object of the present invention to provide a tire inflation pressure control device for a vehicle that can prevent abnormal wear and extend its life.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 자동차의 타이어 공기압 조절장치의 구성도로서, 본 발명은 노면상태에 따른 구분 즉, 포장도로, 비포장도로, 눈길, 빗길, 자갈길, 모래길 등에 따라 타이어 공기압을 지정할 수 있도록 된 노면상태 선택버튼들과 적재상태에 따른 구분 즉, 화물을 적재한 상태와 화물을 적재하지 않은 상태에 따라 공기압을 지정할 수 있도록 된 적재상태 선택버튼들이 구비되어 운전자가 선택조작할 수 있도록 된 조작패널(1)이 제어유니트(2)에 연결되고, 차량에 기설치되어 있는 에어탱크(4)로부터 각 타이어(8)로 공기공급관로가 연결되어 있으며, 이 공기공급관로에 컴프레서(3)가 설치되며, 이 컴프레서(3)와 상기 에어탱크(4) 사이에 마그네틱밸브(5)가 설치되고, 상기 컴프레서(3)의 이후부분에 체크밸브(6)가 설치되며, 상기 공기공급관로의 끝부분인 타이어에 공기를 주입하는 부분 직전에는 쓰리웨이밸브(7)가 설치되고, 상기 제어유니트(2)에 마그네틱밸브(5), 컴프레서(3), 체크밸브(6) 및 쓰리웨이밸브(7)가 연결되는 한편, 상기 제어유니트(2)에 차량의 속도를 측정하는 스피도미터(speedometer ; 9)가 연결되는 구조로 이루어져 있다.1 is a configuration diagram of a tire inflation pressure control apparatus of a vehicle according to the present invention, the present invention is to specify the tire inflation pressure according to the road surface state, that is, pavement, dirt road, snow road, rain road, gravel road, sand road, etc. The road surface selection buttons and the loading status selection buttons that can be used to specify the air pressure according to the loading status, that is, the cargo loading status and the cargo loading status, are provided for the operator to select the operation. The panel (1) is connected to the control unit (2), and the air supply line is connected to each tire (8) from the air tank (4) already installed in the vehicle, and the compressor (3) is connected to the air supply line. A magnetic valve 5 is installed between the compressor 3 and the air tank 4, and a check valve 6 is installed at a later part of the compressor 3, and at the end of the air supply line. A three-way valve 7 is installed just before the air injecting portion to the in-tire, and the control unit 2 has a magnetic valve 5, a compressor 3, a check valve 6 and a three-way valve 7. Is connected to the control unit 2, a speedometer (9) for measuring the speed of the vehicle is configured.

여기서, 상기 제어유니트(2)는 마그네틱밸브(5)를 열어 에어탱크(4)의 공기를 컴프레서(3)로 유입시키고, 컴프레서(3)로 하여금 에어탱크(4)로부터 유입된 공기를 설정압력으로 압축토록 하며, 체크밸브(6)를 열어 압축된 공기를 타이어(8)쪽으로 흐르도록 하고, 상기 쓰리웨이밸브(7)를 개폐하여 타이어(8)의 공기를 빼거나 체크밸브(6)를 통과하여 온 공기를 타이어(8)로 주입하도록 하는 일련의 제어작용을 수행한다.Here, the control unit 2 opens the magnetic valve 5 to introduce air from the air tank 4 into the compressor 3, and causes the compressor 3 to set the air introduced from the air tank 4 into a set pressure. To open the check valve (6) to allow the compressed air to flow toward the tire (8), open and close the three-way valve (7) to release air from the tire (8) or to remove the check valve (6). A series of control actions are performed to inject the air that has passed through to the tire 8.

또한, 스피도미터(9)에서 측정된 차량의 속도에 대한 정보가 제어유니트(2)로 입력되는바, 제어유니트(2)는 측정된 차량의 속도가 60km이상이 되면, 차량이 정상주행상태로 접어든 것으로 판단하고, 상기 마그네틱밸브(5)와 컴프레서(3)와 체크밸브(6)와 쓰리웨이밸브(7)를 제어하여 타이어(8)의 공기압을 정상상태로 회복시키도록 되어 있다.In addition, the information on the speed of the vehicle measured by the speedometer 9 is input to the control unit 2, the control unit 2, when the measured speed of the vehicle is 60km or more, the vehicle is folded into the normal driving state The magnetic valve 5, the compressor 3, the check valve 6 and the three-way valve 7 are controlled to restore the air pressure of the tire 8 to the normal state.

따라서, 운전자가 노면상태나 적재상태에 따라 자가판단하여 상기 조작패널(1)의 버튼을 조작하였을 때, 타이어(8)의 공기압을 감압시켜야 할 경우라면 상기 제어유니트(2)는 쓰리웨이밸브(7)를 개방시켜 타이어(8)의 공기압이 지정된 압력이 될 때까지 배출하고, 타이어(8)의 공기압을 상승시켜야 할 경우라면 쓰리웨이밸브(7)의 방향을 절환시켜 공기가 타이어(8)로 주입될 수 있는 상태로 변경하고, 상기 마그네틱밸브(5)를 열어 에어탱크(4)로부터 컴프레서(3)로 공기를 공급하며, 컴프레서(3)는 공기를 공급받아 제어유니트(2)의 제어에 따라 지정압력까지 공기를 압축시키고, 이후 체크밸브(6)를 개방시켜 압축된 공기가 쓰리웨이밸브(7)를 통해 각 타이어(8)로 주입되도록 되어 있다.Therefore, when the driver determines the air pressure of the tire 8 when the driver self-determines according to the road surface state or the loading state, and the air pressure of the tire 8 is reduced, the control unit 2 is a three-way valve ( 7) is opened and discharged until the air pressure of the tire 8 reaches the specified pressure, and when it is necessary to increase the air pressure of the tire 8, the direction of the three-way valve 7 is switched so that the air is released from the tire 8 The magnetic valve 5 is opened to supply air to the compressor 3 from the air tank 4, and the compressor 3 receives air to control the control unit 2. The air is compressed to a predetermined pressure, and then the check valve 6 is opened so that the compressed air is injected into each tire 8 through the three-way valve 7.

즉, 운전자는 간편한 버튼 조작을 통하여 노면상태나 적재상태에 따라 타이어가 최적의 공기압을 가지도록 조절할 수 있게 되며, 이에 따라 자동차는 타이어에 전달되는 동력의 손실을 최소화시키면서 보다 효율적인 주행을 할 수 있게 되므로 연료의 소비량이 줄어들게 되고, 아울러 타이어가 적정공기압으로 주행하게 되어 이상마모현상이 발생하지 않으므로 타이어의 수명도 연장됨은 물론, 보다 안전한 주행을 할 수 있게 된다.That is, the driver can adjust the tire to have the optimum air pressure according to the road surface or loading state through a simple button operation, so that the car can run more efficiently while minimizing the loss of power transmitted to the tire. As a result, the consumption of fuel is reduced, and at the same time, the tire is driven at an appropriate air pressure so that abnormal abrasion does not occur, thereby extending the life of the tire as well as driving more safely.

한편, 상기와 같이 조절된 공기압으로 주행하다가 차량의 속도가 60km 이상이 되면, 제어유니트(2)는 차량이 정상로에서 주행하는 것으로 인식하고, 각 밸브들과 컴프레서를 조작하여 타이어(8)의 공기압을 본래의 표준공기압으로 회복시킴으로써 정상로에서도 조절된 타이어압력으로 부적절한 주행을 계속하는 것을 방지해준다.On the other hand, when the vehicle speed is 60km or more while driving with the air pressure adjusted as described above, the control unit 2 recognizes that the vehicle is traveling on the normal road, and operates the valves and the compressor to operate the tire 8. By restoring the air pressure to the original standard air pressure, it prevents improper driving even with normal tire pressure even in normal roads.

이는 종래 악로를 통과하기 위해 작동시켰던 차동장치나 인터록장치등을 작동시키지 않아도 되므로, 이들을 작동후 해제하지 않고 주행함으로써 바퀴의 쏠림이 발생하여 사고가 발생되던 위험성을 저감시키는데도 일조할 수 있다.Since it is not necessary to operate the differential device or the interlock device, etc., which have been operated to pass through the conventional path, it may also help to reduce the risk of an accident due to the wheel's tilting by driving without releasing them after operation.

이상 설명한 바와 같이 본 발명에 따르면, 조작패널의 버튼을 선택지정함으로써 타이어의 공기압을 노면상태와 적재상태에 따라 조절할 수 있게 되어 보다 안전하고 효율적인 주행을 할 수 있을 뿐만 아니라 타이어의 수명도 연장시킬 수 있게 되는 효과가 있다.As described above, according to the present invention, by selecting a button on the operation panel, the air pressure of the tire can be adjusted according to the road surface state and the loading state, thereby enabling safer and more efficient driving as well as extending the life of the tire. It is effective to be.
