본 고안은 유압식 파킹 브레이크 장치에 관한 것으로서, 더욱 상세하게는 자동차의 주차 브레이크를 전륜쪽에도 구성하여 비상 상태시 등에 제동력의 향상을 도모한 유압식 파킹 브레이크 장치에 관한 것이다.The present invention relates to a hydraulic parking brake device, and more particularly, to a hydraulic parking brake device configured to improve the braking force in an emergency state by configuring a parking brake of a vehicle on the front wheel side.
일반적으로 자동차에 적용하고 있는 제동장치는 주행하는 자동차를 감속 또는 정지시킴과 아울러 주차상태를 유지하기 위한 장치로서, 마찰력을 이용하여 자동차의 운동에너지를 열에너지로 바꾸어 그것을 대기속으로 방출시키는 작용으로 제동을 행하고 있다.In general, a brake device applied to a vehicle is a device for decelerating or stopping a driving car and maintaining a parking state. The brake device uses a friction force to convert the kinetic energy into thermal energy and release it into the atmosphere. Is doing.
이러한 방식의 제동장치는 휘일 실린더, 브레이크슈 및 이것을 장착하는 백플레이트 그리고 브레이크 드럼 등을 구성 요소로 하는 드럼식 브레이크와 차륜과 함께 회전하는 디스크의 양측에서 유압으로 패드를 가압해 줌으로써 제동을 행하는 디스크식 브레이크로 대분되고 있다.The brake device of this type is a disk type for braking by pressurizing the pads hydraulically on both sides of the rotating disk along with the drum-type brakes and wheels, which include wheel cylinders, brake shoes, back plates and brake drums. It is largely braked.
이러한 제동장치는 바퀴의 안쪽에 결합되어 있는 브레이크 드럼 또는 브레이크 디스크에 마찰재를 붙여서 그 마찰력을 이용하여 제동력을 발생하게 하는데 주로 유압식이 널리 이용되고 있다.Such a braking device attaches a friction material to a brake drum or a brake disc coupled to an inner side of a wheel and generates a braking force by using the friction force, and hydraulic type is widely used.
상기한 유압식 브레이크 시스템은 제동력이 모든 바퀴에 균등하게 전달되고, 마찰 손실도 적음은 물론 조작력도 적게할 수 있는 장점이 있는 반면에 브레이크 파이프 등의 파손으로 브레이크 오일이 누출되면 그 기능을 상실하게 된다.The hydraulic brake system has the advantage that the braking force is equally transmitted to all the wheels, and the friction loss is small as well as the operation force is reduced, whereas the brake oil leaks due to breakage of the brake pipe, etc., and the function is lost. .
따라서 운행중에 브레이크 파이프가 파손되면 운전자는 비상대책 방법의 일환으로 엔진 브레이크를 사용하거나 주차 브레이크를 당기는 등 비상방법을 사용하지만 순간적인 상황에서 대형사고가 초래되는 제반 문제점이 내재되어 있다.Therefore, if the brake pipe is broken during operation, the driver uses an emergency method such as using an engine brake or pulling a parking brake as part of the emergency countermeasure method, but there are inherent problems that cause a large accident in a momentary situation.
본 고안은 상기한 바와 같은 종래의 문제점을 해결하기 위해 고안된 것으로서, 본 고안의 목적은 자동차의 주차 브레이클 전륜쪽에도 구성하여 비상 상태시 등에 제동력의 향상을 도모한 유압식 파킹 브레이크 장치를 제공함에 있다.The present invention has been devised to solve the conventional problems as described above, and an object of the present invention is to provide a hydraulic parking brake device configured to improve the braking force in an emergency situation by also configuring the front side of the parking brake of the vehicle.
상기한 바와 같은 목적을 실현하기 위하여 본 고안은 자동차의 휠 디스크브레이크 장치에 매스터 실린더의 유압이 휠 실린더에 가해져 패드를 부착한 피스톤을 가압하도록 형성된 휠 디스크 브레이크 장치에 있어서, 상기 휠 디스크 브레이크 장치의 캘리퍼 일측에 파킹 실린더를 형성하여 링크와 케이블로 주차 브레이크 레버에 연결하고, 이 주차 브레이크 레버 작동여하에 따라 휠 실린더에 유압을 가압하도록 한 파킹 실린더가 형성됨을 특징으로 한 유압식 파킹 브레이크 장치를 제공하는데 있다.In order to achieve the above object, the present invention provides a wheel disc brake device in which a hydraulic pressure of a master cylinder is applied to a wheel disc brake device of a vehicle to pressurize a piston with a pad. It provides a hydraulic parking brake device, characterized in that the parking cylinder is formed on one side of the caliper, connected to the parking brake lever with a link and a cable, and the parking cylinder is configured to pressurize the wheel cylinder according to the operation of the parking brake lever. have.
이하 본 고안의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 고안으로 자동차의 브레이크 장치에 파킹 실린더를 장착한 구성을 나타내는 도면이고, 제2도의 a)는 본 고안으로 자동차의 브레이크 장치의 비작동시 구성을 나타내는 도면이고, b)는 본 고안으로 자동차의 브레이크 장치의 작동시 구성을 나타내는 도면이다.1 is a view showing a configuration in which the parking cylinder is mounted on the brake device of the vehicle according to the present invention, Figure 2 a) is a view showing the configuration of the non-operation of the brake device of the vehicle by the present invention, b) is the present invention The figure which shows the structure at the time of operation | movement of the brake apparatus of an automobile.
자동차의 휠 디스크 브레이크 장치에 매스터 실린더의 유압이 휠 실린더에 도달하여 패드를 부착한 피스톤을 가압하도록 형성된 휠 디스크 브레이크 장치에 있어서, 상기한 휠 디스크 브레이크 장치(1)의 캘리퍼(3) 일측에 파킹 실린더(5)를 형성한다.A wheel disc brake device configured to pressurize a piston having a pad with the hydraulic pressure of a master cylinder reaching a wheel cylinder of a wheel disc brake device of an automobile, and parking on one side of the caliper 3 of the wheel disc brake device 1 described above. The cylinder 5 is formed.
상기한 파킹 실린더(5)내에 형성된 1,2차 피스톤(7),(9)이 주차 브레이크 레버(도시 생략)에 의해 작동하도록 링크(11)와 케이블(13)로 연결 구성되어 있으며, 또한 1,2차 피스톤(7),(9)이 복원력을 갖도록 1,2차 탄성부재(17),(23)가 탄지되고 1,2차 피스톤(7),(9)을 분리 형성하는 1,2차 분리벽(33),(29)이 형성되어 있다. 1,2차 분리벽(33),(29)의 중심에는 구멍(35),(31)이 형성되어 2차 피스톤(9)의 가압에 의한 유압이 휠 실린더(21)에 용이하게 전달되도록 되어 있다.The primary and secondary pistons 7 and 9 formed in the parking cylinder 5 are connected by a link 11 and a cable 13 so as to be operated by a parking brake lever (not shown). 1,2, the first and second elastic members 17, 23 are supported so that the secondary pistons 7, 9 have a restoring force, and the first and second pistons 7, 9 are separated. The vehicle separation walls 33 and 29 are formed. Holes 35 and 31 are formed in the centers of the primary and secondary separation walls 33 and 29 so that hydraulic pressure due to pressurization of the secondary piston 9 can be easily transmitted to the wheel cylinder 21. have.
또한 파킹 실린더를 통해 매스터 실린더(도시생략)의 유압이 휠 실린더(21)에 가해져서 피스톤(15)이 작동되도록 한 유압식 파킹 브레이크 장치의 구성이다.Moreover, it is the structure of the hydraulic parking brake apparatus which the hydraulic pressure of the master cylinder (not shown) is applied to the wheel cylinder 21 through the parking cylinder, and the piston 15 is operated.
상기한 파킹 실린더(5)를 형성한 디스크 브레이크 장치(1)를 전륜에도 구성하여 주차 브레이크 레버를 당겼을 때 전,후륜 파킹 브레이크 장치가 동시에 작동되도록 한 구성이다.The disc brake device 1 having the above described parking cylinder 5 is also configured on the front wheels so that the front and rear parking brake devices are operated simultaneously when the parking brake lever is pulled.
따라서 상기한 파킹 실린더(5)의 비작동은 브레이크 페달을 밟았을 때의 경우로 제2도의 a)와 같이 피스톤(7),(9)은 정지 상태에 있으므로 매스터 실린더(24)의 유압이 휘일 실린더(21)로 바로 전달되도록하여 디스크 브레이크 장치(1)의 피스톤(5)이 가압 되는 구성이다.Therefore, the non-operation of the above-mentioned parking cylinder 5 is when the brake pedal is pressed, and as shown in a) of FIG. 2, the pistons 7 and 9 are in a stopped state, so the hydraulic pressure of the master cylinder 24 is changed. The piston 5 of the disc brake device 1 is pressurized by being directly transmitted to the cylinder 21.
또한 파킹 실린더(5)의 작동시는 제2도의 b)와 같이 케이블(13)에 연결된 주차 브레이크 레버(도시생략)를 당기면 링크에 의해 피스톤(9)을 가압할 때 피스톤(7)은 왼쪽으로 슬라이드되어 포트(35)를 막아 매스터 실린더(24)의 유압을 차단하고 피스톤(9)에 의해 가압된 유압이 휠 실린더(21)에 도달하여 피스톤(15)을 가압하도록 한 구성이다.In addition, when the parking cylinder 5 is operated, as shown in b) of FIG. 2, when the parking brake lever (not shown) connected to the cable 13 is pulled out, the piston 7 moves to the left when the piston 9 is pressed by the link. It slides and closes the port 35, shuts off the hydraulic pressure of the master cylinder 24, and the hydraulic pressure pressurized by the piston 9 reaches the wheel cylinder 21, and it is the structure which made it pressurize the piston 15. FIG.
상기와 같이 휠 디스크 브레이크 장치(1)에 파킹 실린더(5)를 형성하고 주차 브레이크 레버를 당기면 케이블(13)로 연결된 링크(11)가 2차 피스톤(9)을 민다. 이때 2차 분리벽(29)에는 중심에 구멍(31)이 뚫려 있어 2차 피스톤(9)이 가압될 때 동시에 1차 피스톤(7)도 가압되어 1차 분리벽(33)에 형성되어 있는 구멍(35)을 막도록하여 파킹 실린더(5)내에 유액을 가압하여 휠 실린더(21)에 유압이 가해져 패드를 부착한 피스톤(15)을 가압하는 작용을 한다.As described above, when the parking cylinder 5 is formed on the wheel disc brake device 1 and the parking brake lever is pulled, the link 11 connected by the cable 13 pushes the secondary piston 9. At this time, a hole 31 is drilled in the center of the secondary dividing wall 29 so that when the secondary piston 9 is pressurized, the primary piston 7 is also pressed to form a hole formed in the primary dividing wall 33. (35) is blocked to pressurize the fluid in the parking cylinder (5) to apply hydraulic pressure to the wheel cylinder (21) to pressurize the piston (15) with the pad.
상기한 구멍(31)은 주차 브레이크 레버 조작시 오일의 유동이 이루어지는 구멍으로, 유압과 1차 탄성부재(17)의 탄성력으로 슬라이드 작동하는 개폐가 이루어진다.The hole 31 is a hole through which oil flows when the parking brake lever is operated. The hole 31 is opened and closed to slide by the hydraulic force and the elastic force of the primary elastic member 17.
또, 구멍(35)은 통상 개구되어 브레이크 폐달 답단에 의한 유압이 전달되도록 주차 브레이크 레버 조작시 차단이 이루어지는 구멍이다.In addition, the hole 35 is a hole which is normally opened and blocked when the parking brake lever is operated so that the hydraulic pressure by the brake closing step is transmitted.
따라서 전륜의 휠 디스크 브레이크 장치(1)에 파킹 실린더(5)를 형성하므로서 주차 브레이크 레버를 당기면 동시에 전,후륜 주차 브레이크가 작동되고, 주차 브레이크 레버를 원상태로 복귀시키면 1,2차 탄성부재(17),(23)에 의해 1,2차 피스톤(7),(9)은 비작동시 상태로 복원된다.Therefore, when the parking brake lever is pulled by forming the parking cylinder 5 in the front wheel disc brake device 1, the front and rear parking brakes are operated at the same time, and when the parking brake lever is returned to its original state, the primary and secondary elastic members 17 The primary and secondary pistons 7 and 9 are restored to the non-operational state by means of.
이러한 본 고안은 전륜의 휠 디스크 브레이크 장치에 파킹 실린더를 형성함에 있어 구조가 복잡하지 않고 간단한 구조로 제작할 수 있으며 비상상태시에 전,후륜을 동시에 파킹 브레이크를 작동시킬 수 있기 때문에 제동력이 종래 기술에 비해 월등하고, 또한 종래 후륜 브레이크만을 사용함으로서 마찰력이 적은 곳에서 미끌리는 현상을 해소시킬 수 있는 유용한 고안이다.The present invention can be manufactured in a simple structure without complex structure in forming the parking cylinder on the wheel disk brake device of the front wheel, and the braking force is applied to the prior art because the parking brake can be operated at the same time in the emergency state. Compared to the above, and by using only conventional rear wheel brakes, it is a useful design that can eliminate the phenomenon of slipping in a place where the frictional force is low.
