Description
본 발명은 자동차의 브레이크 시스템에 관한 것이며, 특히 언덕길에서 자동으로 작동하는 안전브레이크장치에 관한 것이다.The present invention relates to a brake system of a motor vehicle, and more particularly, to a safety brake device that automatically operates on a hill.
제동장치(brake system)는 주행하는 자동차를 감속 또는 정지시킴과 동시에 주차상태를 유지하기 위해 사용하는 중요한 장치이며, 일반적으로 마찰력을 이용하여 자동차의 운동에너지를 열에너지로 바꾸어, 그것을 대기속으로 방출시켜 제동작용을 하는 마찰식 브레이크가 사용되고 있다.A brake system is an important device used to keep a car parked at the same time as decelerating or stopping a driving car. In general, a brake system converts the kinetic energy of the car into thermal energy using a friction force and releases it into the atmosphere. Friction brakes with braking action are used.
또한, 제동장치에는 여러형식이 사용되고 있으며, 사용상태에 따라 주행시 제동하기 위한 주브레이크와 주차시 사용하는 주차브레이크가 있다. 주브레이크는 운전자의 발로 조작하므로 푸트브레이크(foot brake)라고 불리며, 주차브레이크는 주로 손으로 조작하기 때문에 핸드브레이크라고도 불린다.In addition, various types are used for the braking device, and there are a main brake for braking when driving and a parking brake for parking. The main brake is called a foot brake because it is operated by the driver's foot, and the parking brake is also called a hand brake because it is mainly operated by hand.
브레이크는 작동방식에 따라 다시 로드나 와이어를 이용하는 기계식과 유압을 이용하는 유압식이 있으며, 일반적으로 푸트 브레이크는 유압식이고 주차브레이크는 기계식이다.Depending on how the brake is operated, there are mechanical methods using hydraulic loads and wires and hydraulic types using hydraulic pressure. In general, the foot brake is hydraulic and the parking brake is mechanical.
유압식브레이크는 그 형식에 따라 드럼식 브레이크와 디스크식 브레이크가 주로 사용되고 있으며, 디스크브레이크는 바퀴와 함께 회전하는 브레이크 디스크의 양측에서 제동패드를 유압에 의하여 눌러서 제동하도록 되어 있으며, 이와 같은 형식을 캘리퍼형(caliper type brake)이라고 부르기도 한다.According to the type of hydraulic brake, the drum type brake and the disc type brake are mainly used. The disc brake is configured to brake by pressing the brake pads by hydraulic pressure on both sides of the brake disc that rotates together with the wheels. Also called a caliper type brake.
도 1에 일반적인 유압브레이크시스템의 구성이 도시되어 있다. 도시의 편의상 전륜과 후륜의 일측의 휠만을 도시하였다.1 shows a configuration of a general hydraulic brake system. For convenience of illustration, only the wheels on one side of the front and rear wheels are illustrated.
도시된 바와 같이, 브레이크페달(1)을 작동시키면 페달아암(1a)에 연결된 푸시로드(1b)에 의해 마스터 실린더(2)내의 피스톤(2a)이 전진하여 실린더(2)내의 브레이크 오일을 압축하므로써 전,후륜측의 브레이크라인(3,4)을 통해 브레이크 오일을 압축하게 되며, 브레이크라인(3,4)의 종단과 연통된 캘리퍼(전륜측)나 브레이크슈(후륜측)의 휠실린더(6,8)로 고압의 브레이크 오일을 공급하여 라이닝이나 패드를 브레이크드럼(내부확장식)이나 디스크(캘리퍼식, 전륜측)에 압착하여 마찰에 의한 제동이 이루어지게 된다. 또한, 브레이크페달을 해방시키면 압축되었던 브레이크 오일이 마스터실린더(2)로 복귀하며 브레이크가 해제되게 된다.As shown, when the brake pedal 1 is operated, the piston 2a in the master cylinder 2 is advanced by the push rod 1b connected to the pedal arm 1a, thereby compressing the brake oil in the cylinder 2. The brake oil is compressed through the brake lines 3 and 4 on the front and rear wheels, and the wheel cylinder 6 of the caliper (front wheel side) or brake shoe (rear wheel side) communicating with the ends of the brake lines 3 and 4. 8) by supplying high pressure brake oil, the lining or pad is pressed against the brake drum (internal expansion type) or the disc (caliper type, front wheel side) to brake by friction. In addition, when the brake pedal is released, the brake oil that has been compressed returns to the master cylinder 2 and the brake is released.
그러나, 상술한 바와 같이 구성된 종래의 브레이크 시스템은 브레이크가 페달의 답력에 의해 작동하게 되므로 내리막 길 등과 같이 제동거리가 길어지는 제동조건하에서는 제동거리를 충분히 확보한 상태에서 페달을 조작하여야 하며, 운전자가 앞차와의 간격을 충분히 유지하지 않은 상태에서 페달을 조작하게 되면, 제동거리가 길어져 추돌사고의 우려가 있으며, 또한, 급브레이크의 작동으로 언덕길에서 차량이 전복될 우려도 크다.However, in the conventional brake system configured as described above, since the brake is operated by the pedaling force of the pedal, under the braking condition such that the braking distance is long, such as a downhill road, the braking distance must be sufficiently operated, and the driver If the pedal is operated without maintaining a sufficient distance from the vehicle in front of the vehicle, the braking distance may be long and a collision may occur, and the vehicle may be overturned on a hill road due to the sudden brake operation.
본 발명은 언덕길에서 앞차와의 간격과 차량의 속도에 따라 자동으로 제동을 수행하여 안전속도를 유지하도록 하므로써 추돌사고나 전복사고를 방지할 수 있는 안전브레이크장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a safety brake device that can prevent a crash or rollover by maintaining a safe speed by automatically braking in accordance with the distance between the vehicle in front of the hill and the speed of the vehicle.
