본 발명은 차량의 브레이크 장치에 관한 것으로, 특히 충돌 시에 에어백이 작동됨과 동시에 차량의 제동이 이루어지도록 브레이크페달을 조작하여 차량 충격을 최소화하며, 브레이크페달과 운전자의 하체가 접촉하여 발생할 수 있는 부상을 최소화할 수 있는 차량의 브레이크장치에 관한 것이다.The present invention relates to a brake device of a vehicle, and in particular, to minimize the impact of the vehicle by manipulating the brake pedal so that the airbag is actuated and the vehicle is braked at the time of a collision, and injuries that may occur when the brake pedal and the lower body of the driver come into contact with each other. It relates to a vehicle brake device that can minimize the.

일반적으로 자동차의 브레이크 장치는 주브레이크와, 주차브레이크가 있다.Generally, a brake device of a vehicle includes a main brake and a parking brake.

주브레이크는 주행 중에 차속을 감속하거나 차량을 정지시키기 위하여 사용되며, 주차브레이크는 주차 시에 차량을 정지상태로 유지하여 차량이 움직이지 못하도록 한다.The main brake is used to slow down the vehicle speed or stop the vehicle while driving, and the parking brake keeps the vehicle stationary when the vehicle is parked to prevent the vehicle from moving.

도 1은 일반적인 차량의 브레이크 장치를 보여주는 도면이다.1 is a view illustrating a brake apparatus of a general vehicle.

이하, 도 1을 참고하여 일반적인 주브레이크 장치를 살펴보면 다음과 같다.Hereinafter, a general main brake device will be described with reference to FIG. 1.

족동식 주브레이크(10)는 브레이크페달(11)에 작용하는 답력에 따라 마스터실린더(12)에 유압이 발생되며, 마스터실린더(12)에서 발생된 유압은 전륜(1)(2)을 제동시키기 위한 캘리퍼(13)의 유압실과, 후륜(3)(4)을 제동시키기 위한 릴리스실린더에 공급된다.The foot-type main brake 10 generates hydraulic pressure in the master cylinder 12 according to the stepping force acting on the brake pedal 11, and the hydraulic pressure generated in the master cylinder 12 causes the front wheels 1 and 2 to brake. It is supplied to the hydraulic chamber of the caliper 13 for release, and the release cylinder for braking the rear wheels 3 and 4. As shown in FIG.

이와 같이 각 차륜(1)(2)(3)(4)에 유압이 작용함으로써 캘리퍼(13)의 패드와브레이크슈의 라이닝이 디스크(14) 및 드럼(15)에 각각 밀착되도록 함으로써 제동이 이루어지게 된다.In this way, the hydraulic pressure acts on each of the wheels 1, 2, 3, and 4 so that the pads of the caliper 13 and the linings of the brake shoes are brought into close contact with the disk 14 and the drum 15, respectively. You lose.
