본 고안은 기존 자동차의 구조 및 사용법을 변경하지 않고 간편하게 연결 부착하여 자동차 제동시 미끄러짐 현상을 완전히 방지하도록 된 자동차 미끄러짐 방지용 유압식 제어 장치에 관한 것이다.The present invention relates to a hydraulic control device for preventing slipping of a vehicle to prevent slippage during braking of a vehicle by simply attaching and changing the structure and usage of an existing vehicle.

종래의 브레이크는 종류에 따라 상당한 차이가 있으나 자동차에 가장 널리 사용되는 유압식 브레이크는 기능이 브레이크 페달을 밟으면 마스터 실린더내의 피스톤은 오일을 휘일 실린더 내에 압송하고, 휘일 실린더는 유압으로 인하여 휘일 디스크나 휘일 드럼에 압력을 가함으로서 휘일이 제동되는 원리로, 이러한 것은 경사진 도로에서 자동차 정지시 브레이크 페달을 밟으며 클러치 페달을 밟아 엔진 동력과 구동부분을 단절한 다음 브레이크 페달을 계속 밟고 있어야 하며, 이 때 자동차는 정지해도 엔진이 여전히 구동됨으로서 재출발시 전진 기어를 넣고 클러치 페달을 밟은 후 브레이크 페달에서 발을 떼어 신속히 엑셀러레이터 페달에 옮겨 밟아서 가속해야 하는 짧은 순간에 자동차는 차체 하중에 의하여 내리막으로 미끄러져 내려가게 된다.Conventional brakes vary considerably depending on the type, but the hydraulic brakes most widely used in automobiles have the function of pressing the brake pedal, the piston in the master cylinder pumps oil into the wheel cylinder, and the wheel cylinder is a wheel disk or wheel drum due to hydraulic pressure. The principle is that the wheels are braked by applying pressure to the brakes, which means that when the car is stopped on a sloping road, the brake pedal must be pressed, the clutch pedal must disconnect the engine power and driving parts, and then the vehicle must continue to press the brake pedal. When the engine is still running, the engine is still running, so when the vehicle is restarted, the forward gear, the clutch pedal are pressed, the foot is released from the brake pedal, and the vehicle is slid downhill by the body load in a short moment to accelerate by stepping on the accelerator pedal.

이와같이 경사진 도로에서 정차 또는 주차후 자동차 출발시에 초보자 또는 운전에 미숙한 운전자들은 조작 미숙으로 시동이 꺼지는등 심리적으로 불안한 출발을 하게 되고, 특히, 내리막으로 미끄러지는등 거리가 길어지는 경우에는 전, 후방 차량과 충돌하여 물적 피해 및 심한 경우 인명 사고를 유발시키는 등의 여러 가지 문제점이 있었다.In this way, when starting or stopping a car on a sloping road, beginners or inexperienced drivers have a psychologically unstable start, such as starting off due to inexperienced operation, especially when the distance is long, such as slipping downhill. In addition, there have been various problems such as collision with a rear vehicle causing physical damage and serious accidents.

본 고안은 이러한 문제점을 해소하기 위하여 안출한 것으로서, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a problem, described in detail based on the accompanying drawings as follows.

본 고안은 제1도에 도시한 바와 같이 크게 피스톤 실린더(1)와 파이로트 체크밸브(2)로 구분되어 좌, 우측 파이프(11)(11')로 상호 연결되고, 내부에 오일이 충만된 유압장치이다.The present invention is largely divided into a piston cylinder (1) and a pilot check valve (2), as shown in FIG. 1, interconnected by left and right pipes (11) and (11 '), and filled with oil therein. It is a hydraulic system.

이러한 본 고안은 피스톤 실린더(1)는 실린더 몸체(3) 내주면 중심부에 피스톤(5)과 스프링(9)이 탄설된 피스톤 로드(6)가 결합 고정되고, 일측이 외부로 연장 돌출된 피스톤로드(6) 말단부(12)에 브레이크 연결부(도시없음)가 구비되며, 파이로트 체크 밸브(2)는 밸브 몸체(4) 내주면 중심부에 밸브(7)와 스프링(10)이 탄설된 파이로트(8)가 결합 고정되고, 피스톤로드(6) 말단부(12)와 상반되게 일측이 외부로 연장 돌출된 파이로트(8) 말단부(13)에 엑셀러레이터 연결부(도시없음)가 구비되어 피스톤 실린더(1)와 파이로트 체크 밸브(2) 사이에는 유로가 형성된 좌, 우측 파이프(11)(11')로 상호 연결 조립된 구성이다.The present invention is a piston cylinder (1) is a piston rod (6) in which the piston (5) and the spring (9) is installed in the center of the inner circumferential surface of the cylinder body (3) is fixedly coupled, one side of the piston rod protruding outward ( 6) A brake connection portion (not shown) is provided at the distal end portion 12, and the pilot check valve 2 includes a pilot 8 in which a valve 7 and a spring 10 are installed at the center of the inner circumferential surface of the valve body 4. Is coupled to the piston rod (6) and the piston rod (6) is provided with an accelerator connection portion (not shown) is provided on the distal end 13 of the pilot 8 protruding outwardly opposite to the distal end 12 of the piston rod (6) It is the structure which was mutually assembled by the left and right pipes 11 and 11 'in which the flow path was formed between the lot check valves 2.

단, 본 고안의 적용시 구성은 동일하나 설치 방향에 따라 파이로트 체크 밸브(2)와 좌, 우측 파이프(11)(11')의 결합 위치는 변형될 수도 있는 것이다.However, the configuration of the present invention is the same, but the coupling position of the pilot check valve 2 and the left and right pipes 11, 11 'according to the installation direction may be modified.

이러한 본 고안의 설치방법은 제1도 및 제3도에 도시한 바와같이, 피스톤 실린더(1)의 피스톤로드(6) 말단부(12)와 마스터 실린더(18)의 푸시로드(14)를 연결하여 브레이크 페달(15)에 결착하고, 파이로트 체크밸브(2)의 파이로트(8) 말단부(13)와 엑셀러레이터 페달(16)를 케이블(17)로 연결하여 사용하도록 된 구조이다.The installation method of the present invention, as shown in FIGS. 1 and 3, by connecting the end of the piston rod (6) 12 of the piston cylinder (1) and the push rod (14) of the master cylinder (18) It is a structure which is attached to the brake pedal 15, and connects the pilot 8 end part 13 of the pilot check valve 2, and the accelerator pedal 16 with the cable 17, and is used.

이와같이 된 본 고안의 작동 상태에 의한 작용효과를 살펴보면 다음과 같다.Looking at the effect by the operating state of the present invention as described above are as follows.

제2a도는 브레이크 페달(15)을 밟는 순간을 도시한 것으로서, 자동차를 주행중 정지하기 위하여 브레이크 페달(15)을 밟는 순간 피스톤로드(6)는 좌측으로 당겨짐과 동시에 피스톤(5) 이동에 의해서 오일은 좌측 파이프(11)를 통하여 이동되면서 유압을 발생시켜 파이로트 체크밸브(2)의 밸브(7)가 열리면서 오일을 이동시켜 우측 파이프(11')를 통하여 피스톤 실린더(1)의 우측 내부 공간부로 오일이 유입 충만되어 유압에 의하여 피스톤(5) 이동이 정지된다.FIG. 2A shows the moment when the brake pedal 15 is pressed, the piston rod 6 is pulled to the left and the oil is moved by the piston 5 at the moment when the brake pedal 15 is pressed to stop the vehicle while driving. The hydraulic pressure is generated while being moved through the left pipe 11, the valve 7 of the pilot check valve 2 is opened, and the oil is moved to the right inner space of the piston cylinder 1 through the right pipe 11 '. This inflow is filled and the movement of the piston 5 is stopped by hydraulic pressure.

제2b도는 브레이크 페달(15)을 밟은 직후를 도시한 것으로서, 제2a도의 작동이 완료된 직후 브레이크 페달(15)을 밟고 있게되면 장치 내부의 오일 이동이 정지되어 평형 상태에 도달하게 되므로서 피스톤 로드(6)는 정지상태가 된다.FIG. 2b shows the brake rod 15 immediately after pressing the brake pedal 15. When the brake pedal 15 is pressed immediately after the operation of FIG. 2a is completed, the oil movement inside the apparatus is stopped to reach an equilibrium state. 6) becomes a stop state.

이때, 파이로트 체크 밸브(2) 내부에 탄설된 스프링(10)의 압력에 의하여 밸브(7)는 즉시 닫히게 되고, 브레이크 페달(15)이 풀리려는 유압의 역방향 이동은 밸브(7)가 닫힘으로서 오일이 역류하지 못하므로 피스톤(5)은 이동되지 않는다.At this time, the valve 7 is immediately closed by the pressure of the spring 10 installed in the pilot check valve 2, and the reverse movement of hydraulic pressure to which the brake pedal 15 is released is performed by closing the valve 7. The piston 5 does not move because the oil does not flow back.

이는 브레이크 페달(15)에서 발을 떼어도 브레이크가 강력히 걸린 상태를 유지하게 되고, 도로의 경사도 및 브레이크의 작동과는 무관하게 자동차는 정지상태를 유지할 수밖에 없다.The brake is strongly held even when the foot is released from the brake pedal 15, and the vehicle is forced to remain stopped regardless of the inclination of the road and the operation of the brake.

제2c도는 자동차 출발시의 상태를 도시한 것으로서, 자동차가 정지된 상태에서 출발시에 운전자는 클러치 페달을 밟고 전진기어를 넣은 후 브레이크 페달(15)에서 발을 떼고 엑셀러레이터 페달(16)을 밟으면 그 힘은 파이로트 체크 밸브(2)의 파이로트(8)에 힘을 가함으로서 닫혀있는 밸브(7)가 열리게 되어 피스톤 실린더(1) 내부에 압축된 스프링(9)의 압력과 브레이크 스프링의 복원력으로 인하여 피스톤 실린더(1)의 피스톤(5)이 우측으로 이동되고 오일은 파이로트 체크 밸브(2)에 열려 있는 밸브(7)를 통하여 좌측 파이프(11)로 이동되어 피스톤 실린더(1)의 피스톤(5)을 원상복귀 시키므로서, 브레이크 페달(15)은 풀린 상태를 유지하여 자동차 주행이 원활하게 되도록 제공한다.FIG. 2C shows the state at the time of starting the vehicle. When the vehicle is stopped, the driver presses the clutch pedal, inserts the forward gear, releases the brake pedal 15, and presses the accelerator pedal 16 when the vehicle starts. The force is applied to the pilot 8 of the pilot check valve 2 to open the closed valve 7 so that the pressure of the spring 9 compressed inside the piston cylinder 1 and the restoring force of the brake spring. Due to this, the piston 5 of the piston cylinder 1 is moved to the right side and the oil is moved to the left pipe 11 through the valve 7 open to the pilot check valve 2 to the piston of the piston cylinder 1 ( By restoring 5), the brake pedal 15 is provided to keep the vehicle running smoothly.

제2d도는 자동차 주행시의 상태를 도시한 것으로서, 전술한 바와 같이 피스톤(5)이 원상복귀되어 브레이크 페달(15)이 완전히 풀린상태에서 파이로트 체크 밸브(2) 내부의 스프링(10) 압력에 의하여 밸브(7)는 다시 닫히게 되고, 피스톤 실린더(1)와 파이로트 체크 밸브(2)의 내부의 오일은 다시 평형 상태가 유지되므로서 자동차 주행에 아무런 영향을 미치지 않는 상태가 된다.FIG. 2d illustrates a state of driving a vehicle. As described above, the piston 5 is returned to its original position and the brake pedal 15 is fully released. The valve 7 is closed again, and the oil in the piston cylinder 1 and the pilot check valve 2 remain in equilibrium again and thus have no influence on driving of the vehicle.

상기와 같은 본 고안은 네가지 동작(제2a, b, c, d도)을 반복하므로서 자동차 주행이 정상적으로 유지되고, 특히, 정지 또는 정차시 브레이크 페달을 밟고 그 즉시 발을 떼어도 항상 브레이크 페달을 밟고 있는 효과가 제공되어 경사진 도로 출발시 충분한 심리적, 시간적 여유가 있으며, 자동차의 미끄러짐을 완전히 방지하여 급가속 출발로 인한 엔진의 과부하 현상을 해소하는 효과가 있도록 매우 유용하게 고안된 것이 특징이다.The present invention, as described above, repeats four operations (2a, b, c, d degrees), and the driving of a vehicle is normally maintained. In particular, the brake pedal is always pressed even when the user presses the brake pedal immediately after stopping or stopping. It is provided with the effect that there is sufficient psychological and time margin at the start of the inclined road, and it is very usefully designed to have the effect of relieving the overload phenomenon of the engine due to the rapid acceleration by completely preventing the slip of the car.
