본 발명은 자동으로 제동되는 자동차 브레이크 시스템에 관한 것으로서 더 상세하게는 브레이크 시스템에 제어 장치를 부착하여 자동차가 마스터 실린더의 작동으로 일차적으로 정지(0km/h)하면 이차적으로 제어장치에 의해서 브레이크 페달을 컨트롤하여 운전자가 브레이크 페달에서 발을 뗄수 있도록 하는 장치에 관한 것이다.The present invention relates to an automobile brake system that is automatically braked, and more particularly, by attaching a control device to the brake system, when the vehicle is primarily stopped (0 km / h) by the operation of the master cylinder, the brake pedal is secondly controlled by the control device. It is about a device that allows the driver to take his foot off the brake pedal.
일반적으로 브레이크 시스템은 주행중의 자동차를 감속 또는 정지시킴과 동시에 주차 상태를 유지하기 위해서 사용되는 중요한 장치이며, 일반적으로 마찰력을 이용하여 자동차의 운동에너지를 열 에너지로 바꾸어 그것을 공기중으로 방산함으로서 제동 작용을 하는 마찰식 브레이크가 사용되고 있다.In general, a brake system is an important device used to maintain a parking state while decelerating or stopping a vehicle while driving. In general, a brake system uses a friction force to convert a vehicle's kinetic energy into thermal energy and dissipate it into the air to provide braking action. Friction brakes are used.
브레이크 장치는 작동이 확실하고 효과가 좋아야하며 신뢰성과 내구성이 뛰어나야함은 물론 검색과 조정이 용이하여야하는 조건을 지녀야하는 것으로서 운전자의 조작력을 링크나 유압을 이용하여 증대시켜 전달하는 조작기구와, 그힘을 받아 제동력을 발생하는 본체로 구성되어진 것이다.The brake system must have the conditions to be sure to operate well, to be effective, to be reliable and durable, to be easy to search and adjust, and to control and increase the driver's operating force by using a link or hydraulic pressure. It is composed of a body that receives the braking force.
일예로 유압식 브레이크는 파스칼의 원리를 적용한 것으로 제 2 도에 도시한 바와 같이 페달(70)을 밟음으로서 유압을 발생하는 마스터 실린더(20), 그 유압을 받아 브레이크 슈(30)를 드럼(40)에 밀어 붙여 제동력을 발생시키는 휠 실린더(50), 유로를 형성하는 브레이크 파이프(60), 호스 등으로 구성되어 있으며 유압식 브레이크는 제동력이 모든 바퀴에 균등하게 전달되어 마찰 손실도 적고 조작력도 적게할 수 있는 등의 이점이 있지만, 브레이크 파이프(60) 등의 파손에 의해 브레이크액 누출이 일어나면 기능을 상실하는 단점과 자동차의 정지시 운전자가 항상 브레이크 페달을 밟아야 하므로 시내 주행시 브레이크 성능은 뛰어나지만 여러 종류의 브레이크 시스템과 마찬가지로 운전자에게 피로를 가중시키는 문제점이 존재하였다.As an example, the hydraulic brake applies the principle of Pascal. As shown in FIG. 2, the master cylinder 20 generates hydraulic pressure by pressing the pedal 70, and the brake shoe 30 receives the hydraulic pressure from the drum 40. It consists of a wheel cylinder (50) that pushes on to generate a braking force, a brake pipe (60) that forms a flow path, a hose, and the like. The hydraulic brake is equally transmitted to all wheels, so that the friction loss is low and the operating force can be reduced. Although there is an advantage such as the brake pipe 60, the brake fluid leakage due to damage such as the loss of function and the driver has to always step on the brake pedal when the vehicle is stopped, so the brake performance is excellent while driving in the city As with the brake system, there has been a problem of adding fatigue to the driver.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한것으로서 브레이크 시스템에 제어 장치를 부착하여 제어 장치가 자동차의 정지시 브레이크 페달을 컨트롤하여 운전자가 브레이크 페달에서 발을 뗄 수 있게하여 운전자의 피로를 격감시키는데 그 목적이 있는 것이다.The present invention has been made to solve the above problems, attached to the control device to the brake system, the control device controls the brake pedal when the vehicle is stopped so that the driver can take his foot off the brake pedal to reduce the fatigue of the driver The purpose is to.
첨부된 도면에 의거하여 본 발명의 구성을 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention in detail based on the accompanying drawings as follows.
제 1 도는 본 발명 브레이크 시스템의 작동 상태도를 도시한 것이다.1 shows an operating state diagram of the brake system of the present invention.
브레이크 페달(70)의 작동으로 마스터 실린더(20)의 유압이 브레이크 슈(30)를 드럼(40)에 압착시켜 제동력을 발생시키는 휠 실린더(50)로 구성되는 브레이크 시스템에 있어서;In the brake system, the hydraulic pressure of the master cylinder (20) by the operation of the brake pedal (70) consists of a wheel cylinder (50) for pressing the brake shoe (30) to the drum (40) to generate a braking force;
오일 탱크(1)에서 압축기(2),오일 펌프(3)를 순환 유압 파이프(6)로 직렬로 배관시키고 오일 펌프(3)의 상 · 하단에 솔레노이드 밸브(4)를 착설시키고 오일 탱크(1)의 하단 브레이크 파이프(5)와 순환 유압 파이프(6)의 교차되는 배관상에 마스터 실린더(20)쪽과 오일 펌프(3)쪽을 개폐시키는 솔레노이드 밸브(4')를 정착하여 솔레노이드 밸브 제어 회로로 컨트롤할 수 있게 구성되어진 것이다.In the oil tank (1), the compressor (2) and the oil pump (3) are piped in series with the circulating hydraulic pipe (6), and the solenoid valve (4) is installed on the upper and lower parts of the oil pump (3) and the oil tank (1) is installed. The solenoid valve control circuit is provided by fixing a solenoid valve 4 'for opening and closing the master cylinder 20 side and the oil pump 3 side on a cross between the lower brake pipe 5 and the circulation hydraulic pipe 6 of It is configured to control with.
본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention.
오일 탱크(1)내의 오일이 오일 압축기(2)를 통해 오일 펌프(3)에서 항상 압축된 상태에서 차가 주행하다가 브레이크 페달(70)을 작동시켜 마스터 실린더(20)의 유압이 브레이크 슈(30)를 드럼(40)에 압착시켜 자동차의 속도가 0km/h이고 기어 상태가 중립이 되면 솔레노이드 밸브 제어회로가 작동해서 압축된 오일 펌프(3)의 밸브를 컨트롤하여 즉 오일 펌프(3)의 상 · 하에 장착된 솔레노이드 밸브(4)가 열고 마스터 실린더(20)쪽 브레이크파이프(5)와 순환 유압 파이프(6)의 교차되는 배관상의 솔레노이드 밸브(4')가 마스터 실린더(20)쪽을 폐쇄시켜 압축된 오일 펌프(3)의 오일이 브레이크 드럼(40)을 계속해서 압착함으로 운전자가 브레이크 페달(70)에서 발을 이탈시켜도 계속해서 제동되는 것이고, 클러치 페달을 한 번 밟음으로서 솔레노이드 밸브제어회로에 의해 마스터 실린더(20)의 솔레노이드 밸브(4')는 개방되면서 오일 펌프(3)측의 배관을 폐쇄시켜 브레이크 드럼(40)을 압착하던 오일은 다시 빠져 나와 오일 탱크(1)에 흘러 들어가게 되며 압축기(2)에 의해 오일 펌프(3)로 재압축되게 되는 것이다.The vehicle travels while the oil in the oil tank 1 is always compressed by the oil pump 3 through the oil compressor 2, and then operates the brake pedal 70 so that the hydraulic pressure of the master cylinder 20 is applied to the brake shoe 30. To the drum 40 and the speed of the vehicle is 0 km / h and the gear state becomes neutral, the solenoid valve control circuit operates to control the valve of the compressed oil pump 3, that is, the top of the oil pump 3 The solenoid valve 4 mounted below opens and the solenoid valve 4 'on the pipe where the brake pipe 5 and the circulating hydraulic pipe 6 intersect the master cylinder 20 is closed and the master cylinder 20 is closed. When the oil of the oil pump 3 is squeezed continuously by the brake drum 40, the driver continues to brake even if the driver releases the foot from the brake pedal 70. The solenoid valve control circuit is operated by pressing the clutch pedal once.The solenoid valve 4 'of the master cylinder 20 opens and closes the pipe on the side of the oil pump 3 so that the oil pressurized by the brake drum 40 is discharged again and flows into the oil tank 1, and the compressor ( 2) to be recompressed to the oil pump (3).
상기한 오일 펌프(3)의 압력은 오일 압력 센서에 의해 설정 압력이 되면 오일 펌프(3) 입구의 솔레노이드 밸브(4)가 닫히고 이하의 압력 상태면 열린 상태로 압축기(2)로부터 오일을 공급받게 되는 것이다.When the pressure of the oil pump 3 reaches the set pressure by the oil pressure sensor, the solenoid valve 4 at the inlet of the oil pump 3 is closed and the oil is supplied from the compressor 2 in an open state when the pressure is below. Will be.
그러므로 본 발명은 차량이 운전되고 있는 동안은 시내에서 차량의 증가로 인해 차량이 자주 정지하는 경우에 자동으로 브레이크 시스템이 파킹됨으로서 운전자의 피로를 줄이면서 편의를 제공할 수 있는 발명인 것이다.Therefore, the present invention is an invention that can provide convenience while reducing the fatigue of the driver by automatically parking the brake system when the vehicle frequently stops due to the increase of vehicles in the city while the vehicle is running.
