Abstract

PURPOSE: A device for compensating air pressure of a tire for a vehicle is provided to keep optimum internal pressure of the tire by automatically taking in air supplied to the engine of the vehicle according to a change of the internal pressure of the tire. CONSTITUTION: A device for compensating air pressure of a tire for a vehicle comprises a controller(50) and an actuator(60). The controller measures and monitors pressure of a super charger(10) and a tire(T). The super charger is connected with a suction intake(IP) through a connection passage(20), to compress air coming in through an inflow line(A) and send the air to a combustion chamber of the engine, with using flow of exhaust gas. The actuator is controlled by the controller, and the actuator opens and shuts a connection line(70) bypassing the compressed air of the connection passage to the tire. The controller receives signals of a pressure sensor(40) mounted to a compressor of the super charger and a pressure sensor(30) disposed in the tire. External air compressed by the super charger is bypassed to the tire when the pressure of the tire is lowered and therefore, pressure of the tire is filled up periodically.

본 발명은 차량의 타이어 공기압 보상장치에 관한 것으로, 보다 상세하게는 과급기를 통해 엔진으로 유입되는 외부 공기를 타이어로 바이패스시킬 수 있도록 된 차량의 타이어 공기압 보상장치에 관한 것이다.The present invention relates to a tire inflation pressure compensator for a vehicle, and more particularly, to a tire inflation compensator for a vehicle that enables bypass of external air introduced into an engine through a supercharger to a tire.

일반적으로 차량의 타이어는 주행 시 적정한 공기압력을 유지해야만 제동시나 주행 시 제동거리의 불필요한 증가나 연료의 과 소모를 방지할 수 있으므로, 타이어는 압력 저하시 운전자가 직접 공기를 주입할 수 있도록 노출된 공기 주입구를 구비하게 된다.Generally, tires of a vehicle must maintain proper air pressure when driving to prevent unnecessary increase in braking distance or excessive consumption of fuel during braking or driving. Therefore, tires are exposed so that the driver can directly inject air when the pressure decreases. It is provided with an air inlet.

즉, 회전력을 전달하는 등속조인트에 결합된 허브를 매개로 고정된 타이어의 림부위로 공기 주입구가 노출되어져 이를 통해 공기를 충진하고 공기압을 적정하게 유지시키게 된다.That is, the air inlet is exposed to the rim of the tire fixed by the hub coupled to the constant velocity joint that transmits the rotational force, thereby filling the air and maintaining the air pressure appropriately.

그러나, 이와 같은 타이어의 공기 주입구는 차량을 정지시킨 상태에서 공기 주입용 펌핑 도구를 이용할 수밖에 없고 또한, 주행 중 펑크가 날 경우 타이어의 압력 유지가 불가능해 운전 조작의 미숙으로 인한 대형 사고를 발생시킬 수 있는 문제가 있게 된다.However, such an air inlet of the tire has to use a pumping tool for injecting air while the vehicle is stopped, and also, if a puncture occurs while driving, it is impossible to maintain the pressure of the tire and cause a large accident due to immature driving operation. There will be a problem.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량의 엔진으로 공급되는 공기를 타이어의 내압 변화에 따라 자동으로 유입시켜 항상 최적의 타이어 내압을 유지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described problems, and an object thereof is to maintain the optimum tire internal pressure at all times by automatically introducing air supplied to the engine of the vehicle according to the change in the internal pressure of the tire.

상기와 같은 목적을 달성하기 위한 본 발명은, 배기가스의 흐름을 이용해 유입라인을 통해 유입되는 공기를 압축시켜 엔진의 연소실로 보내도록 흡기인테이크와 연결통로를 매개로 이어진 과급기의 압력과 타이어의 압력을 측정하여 모니터링하는 콘트롤러와, 이 콘트롤러에 의해 제어되어 상기 연결통로의 압축공기를 타이어로 바이패스시키는 연결라인을 개·폐시키는 액튜에이터로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the pressure of the supercharger and the pressure of the tire connected through the intake intake and the connection passage to compress the air flowing through the inlet line using the exhaust gas flow to the combustion chamber of the engine It is characterized in that it comprises a controller for measuring and monitoring the controller, and an actuator controlled by the controller to open and close the connection line for bypassing the compressed air of the connection passage to the tire.

도 1은 본 발명에 따른 과급기를 이용한 차량의 타이어 공기압 보상장치의 구성도를 도시한 것인바, 본 발명은 배기가스의 흐름을 이용해 유입라인(A)을 통해 유입되는 공기를 압축시켜 엔진(E)의 연소실로 보내도록 흡기인테이크(IP)와 연결통로(20)를 매개로 이어진 과급기(10)의 압력과 타이어(T)의 압력을 측정하여 모니터링하는 콘트롤러(50)와, 이 콘트롤러(50)에 의해 제어되어 상기 연결통로(20)의 압축공기를 타이어(T)로 바이패스(Bypass)시키는 연결라인(70)을 개·폐시키는 액튜에이터(60)로 이루어진다.1 is a block diagram of a tire inflation pressure compensator for a vehicle using a turbocharger according to the present invention. The present invention compresses the air flowing through the inflow line A by using the flow of the exhaust gas engine E. The controller 50 for monitoring and measuring the pressure of the supercharger 10 and the pressure of the tire T connected to the intake intake IP and the connecting passage 20 to be sent to the combustion chamber of Controlled by the actuator consists of an actuator 60 for opening and closing the connection line 70 for bypassing the compressed air of the connection passage 20 to the tire (T).

여기서, 상기 콘트롤러(50)는 과급기(10)와 타이어(T)의 압력을 각각 측정하도록 과급기(10)의 컴프레셔부위에 구비된 압력센서(40)와 타이어(T)내에 구비된 압력센서(30)의 신호를 전송받게 됨은 물론이다.Here, the controller 50 is a pressure sensor 30 provided in the compressor portion of the turbocharger 10 and the pressure sensor 30 provided in the tire T to measure the pressure of the turbocharger 10 and the tire T, respectively. Of course, you will receive a signal of).

또한, 상기 연결라인(70)에는 타이어(T)의 압력이 과급기(10)의 연결라인(20)압력보다 높더라도 역류되지 않도록 일 방향의 첵밸브(80)가 구비되어진다.In addition, the connection line 70 is provided with a check valve 80 in one direction so that the pressure of the tire T is not reversed even if the pressure of the tire T is higher than the pressure of the connection line 20 of the supercharger 10.

이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

일반적으로, 과급기(10)는 차량의 엔진에 장착된 배기인테이크(EP)에 연결된배기라인(B)을 통해 배출되는 배기가스에 의해 회전되는 터빈과 함께 회전되는 컴프레셔을 통해 흡기라인(A)으로 유입되는 외부공기를 압축하여 배기인테이크(EP)로 연결되는 연결통로(20)를 통해 엔진(E)으로 공급하는 즉, 배기가스의 압력을 이용해 엔진으로 유입되는 외부공기를 압축하여 엔진 성능을 향상시키는 것이다.In general, the supercharger 10 flows into the intake line A through a compressor that is rotated together with a turbine that is rotated by an exhaust gas discharged through an exhaust line B connected to an exhaust intake EP mounted to an engine of the vehicle. Compressed air is supplied to the engine (E) through the connection passage 20 connected to the exhaust intake (EP), that is, to improve the engine performance by compressing the external air flowing into the engine using the pressure of the exhaust gas will be.

이에 따라, 본 발명은 이러한 과급기(10)에 의해 압축되는 유입공기의 압력을 이용해 타이어(T)의 압력을 보충하는 것으로 즉, 콘트롤러(50)가 타이어(T)내의 압력을 압력센서(30)를 통해 지속적으로 모니터링하면서 설정 값 이하로 타이어(T)의 압력이 저하되면, 상기 콘트롤러(50)가 과급기(10)에 구비된 압력센서(40)를 통해 모니터링된 유입공기의 압력과 비교하여 타이어(T)로 유입시키게 된다.Accordingly, the present invention supplements the pressure of the tire T by using the pressure of the intake air compressed by the supercharger 10, that is, the controller 50 controls the pressure in the tire T to the pressure sensor 30. If the pressure of the tire (T) falls below the set value while continuously monitoring through the controller, the controller 50 is compared with the pressure of the inlet air monitored through the pressure sensor 40 provided in the supercharger 10. To (T).

즉, 상기 콘트롤러(50)가 과급기(10)의 유입공기의 압력이 충분하고 타이어(T)의 압력이 저하되어 압력의 보충이 필요하다고 판단되면, 상기 콘트롤러(50)가 연결라인(70)에 구비된 액튜에이터(60)를 온(On)시켜 통로를 열어 엔진(E)으로 공급되는 유입공기를 타이어(T)로 바이패스시켜 타이어(T)의 압력을 상승시키게 된다.That is, when the controller 50 determines that the pressure of the inlet air of the supercharger 10 is sufficient and that the pressure of the tire T is lowered and the pressure needs to be supplemented, the controller 50 is connected to the connection line 70. By turning on the provided actuator (60) to open the passage to bypass the inlet air supplied to the engine (E) to the tire (T) to increase the pressure of the tire (T).

이어, 상기 콘트롤러(50)가 압력센서(30)를 통해 액튜에이터(60)에 의해 연결라인(70)을 통해 유입된 공기에 의해 타이어(T)의 압력이 다시 설정 값까지 높아진 것을 확인하면 다시 상기 액튜에이터(60)를 오프(Off)시켜 연결라인(70)의 통로를 닫아 유입공기의 유입을 차단하게 된다.Subsequently, when the controller 50 confirms that the pressure of the tire T is increased to the set value again by the air introduced through the connection line 70 by the actuator 60 through the pressure sensor 30, the pressure is increased again. The actuator 60 is turned off to close the passage of the connection line 70 to block the inflow of inlet air.

한편, 상기 연결라인(70)에 구비된 첵밸브(80)는 타이어(T)의 압력이 과급기(10)의 압력보다 높더라도 타이어(T)의 공기가 과급기(10)쪽으로 역류되는것을 방지하게 됨은 물론이다.Meanwhile, the check valve 80 provided in the connection line 70 prevents the air of the tire T from flowing back toward the supercharger 10 even if the pressure of the tire T is higher than the pressure of the supercharger 10. Of course.

이상 설명한 바와 같이 본 발명에 의하면, 배기가스의 압력을 이용해 작동되는 과급기에 의해 압축된 외부공기를 타이어의 압력저하 시 타이어쪽으로 바이패스시켜 타이어의 압력을 주기적으로 보충하게 되어 항상 최적의 타이어 내압을 유지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the external air compressed by the supercharger operated by using the exhaust gas pressure is bypassed to the tire when the pressure decreases, thereby periodically replenishing the tire pressure so that the optimum tire internal pressure is always maintained. There is a sustainable effect.
