Description

브레이크 장치Brake device

본 발명은 브레이크 시스템에 관한 것이며, 특히 기계식과 유압식을 조합한 형태의 새로운 브레이크 시스템에 관한 것이다.The present invention relates to a brake system, and more particularly to a new brake system of a combination of mechanical and hydraulic.

자동차의 브레이크시스템으로는 기계식, 유압식 및 공기압식이 개발되어 있으나, 유압식 브레이크시스템이 주로 사용된다.Mechanical, hydraulic and pneumatic brake systems have been developed, but hydraulic brake systems are mainly used.

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(la)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 실린더(6, 8)로 고압의 브레이크 오일을 공급하여 라이닝이나 패드를 브레이크드럼(내부확장식, 후륜)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 la, 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 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 the brake oil of high pressure, the braking by friction is performed by pressing the lining or pad to the brake drum (internal extension type, rear wheel) or disc (caliper type, front wheel side). 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.

한편, 도 2에 종래의 캘리퍼타입의 휠측 브레이크의 구성이 도시되어 있다.On the other hand, Fig. 2 shows the configuration of a conventional caliper type wheel side brake.

도시된 바와 같이, 캘리퍼형 브레이크는 상술한 바와 같이 브레이크유압라인(3, 4)를 통해 캘리퍼(6)의 양측의 실린더로 제공된 작동유가 디스크(10)의 양측에서 피스톤(11)의 종단에 형성된 브레이크패드(12)를 가압하여 제동이 이루어지게 된다.As shown, the caliper type brake has hydraulic oil provided to the cylinders on both sides of the caliper 6 via the brake hydraulic lines 3 and 4, as described above, formed at the end of the piston 11 on both sides of the disk 10. Braking is achieved by pressing the brake pad 12.

그러나, 기존의 유압식 브레이크는 제동력은 우수하나 각 휠에 유압을 보내 장치가 복잡하고 유암호스나 파이프가 터지면 브레이크가 작동하지 않으므로 시스템의 안정성은 기계식에 비해 떨어진다.However, conventional hydraulic brakes have excellent braking force but send hydraulic pressure to each wheel, which makes the system complicated and the brakes do not work when the oil hose or pipe is blown.

본 발명의 목적은 기계식과 유압식을 복합하여 시스템의 안전성과 제동력을 아울러 갖춘 기계식과 유압식을 조합한 타입의 새로운 형태의 브레이크 장치를 제공하는 것이다.It is an object of the present invention to provide a new type of brake device of a combination of a mechanical and hydraulic type which combines a mechanical and hydraulic type with the safety and braking force of the system.

제1도는 일반적인 유압식 브레이크 장치의 구성을 도시하는 개략적인 구성도이다.1 is a schematic configuration diagram showing the configuration of a general hydraulic brake device.

제2도는 종래의 캘리퍼형 브레이크의 구성을 도시하는 구성단면도이다.2 is a sectional view showing the construction of a conventional caliper brake.

제3도는 본 발명에 따른 브레이크 장치의 구성을 도시하는 구성도이다.3 is a configuration diagram showing the configuration of a brake device according to the present invention.
