본 고안은 배기압을 이용한 미끄럼방지용 브레이크 장치에 관한 것이다.The present invention relates to a non-slip brake device using exhaust pressure.

일반적으로, 자동차의 브레이크 장치는 푸트 브레이크와 주차 브레이크로 구분되는 바, 상기한 푸트 브레이크는 승용차의 경우 유압을 사용하여 4륜에 장착된 디스크 브레이크 또는 드럼 브레이크를 제어함으로써 자동차의 제동력을 발생시키게 되는 것이다.In general, a brake device of a vehicle is classified into a foot brake and a parking brake. The foot brake generates a braking force of a vehicle by controlling a disc brake or a drum brake mounted on four wheels using hydraulic pressure in a passenger car. will be.

여기서, 상기한 브레이크 장치는 회전되는 타이어를 유압으로 정지시킴으로써 상기한 타이어와 노면의 마찰에 의해 차량을 정지시키게 되는 바, 이는 도 2에 도시된 바와 같이 브레이크 페달(50)과, 상기한 브레이크 페달(50)에 연결되어 있는 마스터 실린더(51)와, 상기한 마스터 실린더(51)와 연결되어 있을 뿐만 아니라 고압 공기가 인가되는 부스터(52)와, 상기한 마스터 실린더(51)와 연결되어 있는 전, 후륜 브레이크(53, 54)로 구성되어 있다.Here, the brake device is to stop the vehicle by the friction of the tire and the road surface by hydraulically stopping the rotating tire, which is the brake pedal 50 and the brake pedal as shown in FIG. The master cylinder 51 connected to 50, the booster 52 not only connected to the master cylinder 51 described above, but also to which the high pressure air is applied, and the master cylinder 51 connected to the master cylinder 51 described above. And rear wheel brakes 53 and 54.

즉, 페달 답력과 부스터(52)의 배력에 의한 유압이 전, 후륜 브레이크(53, 54)의 휠 실린더(미 도시)를 제어함으로써 제동력을 발생시키게 되는 것이다.That is, the hydraulic pressure generated by the pedal effort and the booster 52 boosts the braking force by controlling the wheel cylinders (not shown) of the front and rear wheel brakes 53 and 54.

상기한 목적을 실현하기 위하여 본 고안은 차량의 배기압을 이용하여 경사로 주정차시 운전자가 브레이크 페달에서 발을 뗌과 동시에 악셀러레이터 페달을 밟으면 브레이크 페달을 당겨 제동력을 확보하도록 구성된 보조제동수단이 부스터에 연결 설치하여 구성함을 특징으로 한다.In order to achieve the above object, the present invention provides an auxiliary braking means configured to secure a braking force by pulling the brake pedal when the driver steps out of the brake pedal and stops the accelerator pedal at the same time using the exhaust pressure of the vehicle. It is characterized in that the installation by connecting to.

이하, 본 고안에 대하여 첨부된 도면에 따라 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 1은 본 고안에 따른 자동차용 브레이크 장치를 도시한 개략도이다.1 is a schematic view showing a brake device for a vehicle according to the present invention.

도시된 바와 같이, 경사로 주정차 시 운전자가 브레이크 페달(50)에서 발을 뗌과 동시에 악셀러레이터 페달(A)을 밟으면 브레이크 페달(50)을 당겨 제동력을 확보하도록 구성된 보조 제동 수단이 부스터(52)에 연결 설치되어 있다.As shown, the auxiliary braking means configured to pull the brake pedal 50 to secure the braking force when the driver steps out of the brake pedal 50 and presses the accelerator pedal A at the same time as the driver stops the booster 52. Connected to

상기한 보조 제동 수단은 부스터(52)에 고정됨과 아울러 부스터 로드(R)가 돌출된 커버(1)와, 상기한 부스터 로드(R)에 형성된 피스톤(2)과, 상기한 피스톤(2)과 커버(1) 사이에 개재된 백(3)과, 상기한 악셀러레이터 페달(A) 이격 시 백(3)을 팽창시키도록 구성된 팽창 수단과, 상기한 팽창 수단을 동작시키도록 연결 설치됨과 아울러 휠 센서(4) 및 경사 센서(5)와 악셀러레이터 페달 스위치(6)가 연결된 ECU(7)로 구성되어 있다.The auxiliary braking means is fixed to the booster 52, and the cover 1 in which the booster rod R protrudes, the piston 2 formed on the booster rod R, the piston 2 and A bag (3) interposed between the cover (1), an expansion means configured to expand the bag (3) when the accelerator pedal (A) is spaced apart, and is connected and installed to operate the expansion means. The wheel sensor 4, the inclination sensor 5, and the accelerator pedal switch 6 are comprised by the ECU 7 connected.

즉, 경사로에서 출발 시 브레이크 페달(50)에서 발을 떼게 되면 ECU(7)가 팽창 수단을 동작시킴과 아울러 백(3)을 팽창시켜 부스터 로드(R)가 압박되면서 제동 작용이 이루어지게 되는 것이다.That is, when the foot is released from the brake pedal 50 at the start of the ramp, the ECU 7 operates the expansion means and expands the bag 3 so that the booster rod R is pressed to perform a braking action. .

상기한 팽창 수단은 백(3)에 배관(8)으로 연결됨과 아울러 상기한 배관(8)의 사이에 ECU(7)에 연결되어 있는 솔레노이드 밸브(9)가 설치된 탱크(10)와, 상기한 탱크(10)에 배기 기스가 유입되도록 연결됨과 아울러 흡입, 배기 밸브(11, 12)를 개재하여 연결된 흡입, 배출 배관(13, 14)으로 구성되어 있다.The expansion means is a tank (10) provided with a solenoid valve (9) connected to the bag (3) by a pipe (8) and connected to the ECU (7) between the pipes (8), The exhaust gas flows into the tank 10 and is composed of suction and discharge pipes 13 and 14 connected through the suction and exhaust valves 11 and 12.

상기한 바와 같은 본 고안의 작용 효과를 설명하면 자동차의 주행중 경사로에 차량이 주정차하게 되면 경사 센서(5)를 통해 ECU(7)가 이를 판단하게 된다.Referring to the operation and effect of the present invention as described above, when the vehicle is parked on the ramp while the vehicle is running, the ECU 7 determines this through the inclination sensor 5.

ECU(7)가 차량의 경사 상태를 판단하게 되면 현재 차량의 휠 센서(4)가 정지 상태를 판별하게 되는 바, 운전자가 브레이크 페달(50)에서 발을 떼게 되면 ECU(7)가 솔레노이드 밸브(9)를 개방시키게 된다.When the ECU 7 determines the inclination state of the vehicle, the wheel sensor 4 of the current vehicle determines the stop state. When the driver releases the brake pedal 50, the ECU 7 causes the solenoid valve ( 9) is opened.

이때, 상기한 배기 파이프(E)의 배기 가스가 흡입 배관(13)과 흡입 밸브(11)를 통해 탱크(10)에 충만되어 있는 상태이기 때문에 솔레노이드 밸브(9)를 통해 백(3)에 배기 가스가 충진된다.At this time, since the exhaust gas of the exhaust pipe E is filled in the tank 10 through the intake pipe 13 and the intake valve 11, the exhaust gas is exhausted to the bag 3 through the solenoid valve 9. The gas is filled.

백(3)에 배기 가스가 충진되면 팽창되면서 피스톤(2)을 압박하게 되고, 피스톤(2)의 압박에 의해 부스터(52)가 동작하게 됨으로써 브레이크가 동작된다.When the exhaust gas is filled in the bag 3, the piston 2 is pushed while expanding, and the booster 52 is operated by the pressure of the piston 2 to operate the brake.

즉, 운전자가 브레이크 페달(50)에서 발을 떼고 악셀러레이터 페달(A)을 밟는 시간 사이에 백(3)이 브레이크를 동작시켜 차량이 후진되지 않도록 하는 것이다.That is, the bag 3 operates the brake between the time when the driver takes his foot off the brake pedal 50 and presses the accelerator pedal A so that the vehicle does not move backward.

물론, 악셀러레이터 페달(A)을 밟게 되면 ECU(7)가 이를 체크하여 솔레노이드 밸브(9)를 차단시키게 됨으로써 백(3)에 충진된 배기 가스가 배기되고, 제동 작용을 해제시키게 되는 것이다.Of course, when the accelerator pedal A is pressed, the ECU 7 checks this to shut off the solenoid valve 9, thereby exhausting the exhaust gas filled in the bag 3, thereby releasing the braking action.

제동 작용이 해제되면 운전자가 악셀러레이터 페달(A)을 밟고 정상 출발 가능하게 된다.When the braking action is released, the driver presses the accelerator pedal A and can start normally.

이상과 같이 본 고안은 배기 가스의 압력을 통해 경사로 출발 시 브레이크를 동작시킴으로써 차량이 뒤로 밀리는 것을 방지할 수 있는 효과가 있는 것이다.As described above, the present invention has an effect of preventing the vehicle from being pushed back by operating the brake at the start of the ramp through the pressure of the exhaust gas.
