Description
본 고안은 차량을 정지시키는 브레이크 장치에 관한 것으로서, 특히 브레이크 페달에 의한 제동력을 전륜과 후륜으로 분배하는 제동력 배분 장치에 관한 것이다.The present invention relates to a brake device for stopping a vehicle, and more particularly to a braking force distribution device for distributing the braking force by the brake pedal to the front wheel and the rear wheel.
일반적으로 자동차의 브레이크 장치는 각 바퀴에 설치된 브레이크 본체와, 브레이크 페달의 조작력을 상기 브레이크 본체로 전달하는 브레이크 본체로 구성되어 있다. 따라서, 운전자가 브레이크 페달을 밟으면 유압 등에 의하여 브레이크 본체가 작동됨으로써 각 바퀴에 제동력을 가하게 된다.In general, a brake device of an automobile is composed of a brake body provided on each wheel, and a brake body that transmits the operating force of the brake pedal to the brake body. Therefore, when the driver presses the brake pedal, the brake body is operated by hydraulic pressure or the like to apply braking force to each wheel.
여기서 각 바퀴에 걸리는 제동력을 살펴보면 도 1에 도시된 바와 같이 프런트 제동력과 리어 제동력이 동일하게 배분된다. 그러나, 실험에 의한 이상적인 제동력은 제동 초기에는 리어측에 더 많은 제동력이 필요하고 그 후로는 프런트측에 더 많은 제동력이 필요함을 알 수 있다.Here, looking at the braking force applied to each wheel, the front braking force and the rear braking force are equally distributed as shown in FIG. 1. However, it can be seen that the experimentally ideal braking force requires more braking force on the rear side at the beginning of braking and more braking force on the front side thereafter.
즉, 종래의 제동 장치는 전륜과 후륜에 동일한 제동력이 인가되어 제동 효율이 떨어지는 문제점이 있다.That is, the conventional braking device has a problem in that braking efficiency is lowered because the same braking force is applied to the front wheel and the rear wheel.
본 고안은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 차량의 감속도를 센싱하여 전륜과 후륜으로 제동력을 적절하게 분배함으로써 실제의 제동선이 이상 제동선에 근접할 수 있도록 하여 최대한의 제동 효과를 얻을 수 있도록 하는 제동력 배분 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, by sensing the deceleration of the vehicle to properly distribute the braking force to the front and rear wheels so that the actual braking line can be close to the abnormal braking line It is an object of the present invention to provide a braking force distribution device capable of obtaining a braking effect.

상기한 목적을 달성하기 위한 본 고안은 브레이크 페달에 의해 발생된 유압이 일시 저장되는 오일 챔버와, 상기 오일 챔버의 하측에 설치되어 차량의 감속도를 감지하는 중추와, 상기 오일 챔버에 설치되고 상기 중추에 의해 감지된 감속도에 따라 프런트측과 리어측으로 유압을 분배하는 밸브로 구성된 것을 특징으로 한다.The present invention for achieving the above object is an oil chamber in which the hydraulic pressure generated by the brake pedal is temporarily stored, the central portion is installed on the lower side of the oil chamber to detect the deceleration of the vehicle, the oil chamber is installed in the It is characterized by consisting of a valve for distributing the hydraulic pressure to the front side and the rear side in accordance with the deceleration detected by the center.
이하, 본 고안의 바람직한 실시 예를 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
본 고안에 의한 제동력 배분 장치는 도 2에 도시된 바와 같이 브레이크 페달에 의해 발생된 유압이 일시 저장되는 오일 챔버(51)와, 상기 오일 챔버(51)의 하측에 설치되어 차량의 감속도를 감지하는 중추(52)와, 상기 오일 챔버(51)에 설치되고 상기 중추(52)에 의해 감지된 감속도에 따라 프런트측과 리어측으로 유압을 분배하는 밸브(53)로 구성되고; 상기 밸브(53)는 프런트측 통로(55a)와 리어측 통로(55b)가 형성된 하우징(53a)과, 상기 하우징(53a)에 설치되고 하측에 상기 중추(52)가 연결되어 그 경사각의 변화되는 본체(53b)와, 상기 본체(53b)를 탄발시키는 리턴 스프링(53c)으로 구성된다.As shown in FIG. 2, the braking force distribution device according to the present invention has an oil chamber 51 temporarily storing hydraulic pressure generated by a brake pedal and a lower side of the oil chamber 51 to detect a deceleration of a vehicle. And a valve (53) installed in the oil chamber (51) and distributing hydraulic pressure to the front side and the rear side according to the deceleration sensed by the weight (52); The valve 53 has a housing 53a having a front side passage 55a and a rear side passage 55b, and a central portion 52 connected to the housing 53a and connected to the lower side thereof so that its inclination angle is changed. It consists of a main body 53b and the return spring 53c which shots the main body 53b.
상기와 같이 구성된 본 고안의 제동력 배분 장치는 제동시 감속도에 따라 중추가 밸브 본체의 경사각을 변화시켜 제동력을 프런트측과 리어측으로 배분하도록 되어 있다.The braking force distribution device of the present invention configured as described above is configured to distribute the braking force to the front side and the rear side by changing the inclination angle of the valve body according to the deceleration during braking.
제동력 분배 장치가 차량에 설치되면 중추(52)에 의해 리턴 스프링(53c)이 늘어나면서 본체(53b)가 유압 통로(55a,55b)를 차단하게 된다. 차량이 주행중일 때에는 중추(52)의 영향으로 본체(53b)가 리어측으로 기울게 되므로 제동 초기에는 오일 챔버(51)의 유압이 리어측으로 집중된다. 따라서, 리어측의 제동력이 프런트측에 비해 커지게 되고, 제동이 진행됨에 따라 중추(52)가 앞으로 이동되면서 본체의 경사각이 변화되므로 프런트측으로 전달되는 제동력이 점차적으로 커지게 된다.When the braking force distribution device is installed in the vehicle, the return spring 53c is extended by the weight 52 so that the main body 53b blocks the hydraulic passages 55a and 55b. When the vehicle is running, the main body 53b is inclined to the rear side under the influence of the weight 52, so that the oil pressure of the oil chamber 51 is concentrated to the rear side at the initial braking time. Accordingly, the braking force of the rear side is increased compared to the front side, and as the braking proceeds, as the weight 52 moves forward, the inclination angle of the main body is changed, so that the braking force transmitted to the front side is gradually increased.
즉, 본 고안의 제동력 분배 장치가 적용될 경우 도 4에 도시된 바와 같이 이상 제동선과 거의 유사한 제동선을 얻을 수 있다.That is, when the braking force distribution device of the present invention is applied, a braking line almost similar to the abnormal braking line can be obtained as shown in FIG. 4.
이와 같이, 본 고안에 의한 제동력 배분 장치는 감속도에 따라 프런트측과 리어측의 제동력을 제어하여 제동시의 제동선을 이상 제동선에 근접시킬 수 있으므로 제동 효과를 향상시킬 수 있는 이점이 있다.As described above, the braking force distribution device according to the present invention can control the braking force of the front side and the rear side according to the deceleration to bring the braking line at the time of braking to the abnormal braking line, thereby improving the braking effect.
