브레이크 디스크 부식 방지 구조{CORROSION PREVENTING STRUCTURE OF BRAKE DISK}Brake disc anti-corrosion structure {CORROSION PREVENTING STRUCTURE OF BRAKE DISK}

본 발명은 브레이크 디스크 부식 방지 구조에 관한 것으로서, 더욱 상세하게는 희생 양극 물질과 전기회로를 이용하여 브레이크 디스크의 부식을 방지하는 브레이크 디스크 부식 방지 구조에 관한 것이다.The present invention relates to a brake disc anti-corrosion structure, and more particularly to a brake disc anti-corrosion structure that prevents corrosion of the brake disc by using a sacrificial anode material and an electric circuit.

일반적으로 브레이크 디스크는 브레이크 패드를 압착시켜 제동 효과를 발생시키는 것으로, 이러한 브레이크 디스크는 제동면에서 장기 판매 대기 및 판매 지역 환경 조건(강우량, 온도, 습도 등)에 따른 부식이 발생하며, 상기와 같이 브레이크 디스크의 부식을 방지하기 위해 표면 처리를 실시한다.In general, a brake disc compresses the brake pads to generate a braking effect. Such brake discs generate corrosion on the braking surface according to the long-term stand-by and sales region environmental conditions (rainfall, temperature, humidity, etc.). Surface treatment is performed to prevent corrosion of the brake discs.

즉, 브레이크 디스크의 표면처리 방법은 브레이크 디스크의 표면을 세척하는 세척 단계, 상기 브레이크 디스크의 제동면을 포함한 전면에 표면처리제로 피막을 형성하는 도장 단계, 상기 브레이크 디스크를 고주파로 가열경화하는 건조 단계, 상기 브레이크 디스크를 냉각시키는 냉각 단계, 및 상기 브레이크 디스크의 표면을 브러싱하는 브러싱 단계를 포함한다.That is, the surface treatment method of the brake disc includes a washing step of washing the surface of the brake disc, a coating step of forming a film with a surface treatment agent on the front surface including the braking surface of the brake disc, and a drying step of heating and curing the brake disc at high frequency. A cooling step of cooling the brake disc, and a brushing step of brushing the surface of the brake disc.

상기와 같이 브레이크 디스크를 표면 처리함으로써 제동면을 포함한 전면에 서 표면처리제 성분에 의해 내식성이 향상되어 부식 발생을 방지한다.By surface treatment of the brake disc as described above, the corrosion resistance is improved by the surface treating agent component on the front surface including the braking surface, thereby preventing the occurrence of corrosion.

그러나 종래의 브레이크 디스크는 브레이크 제동에 의해 브레이크 디스크의 제동면에 형성된 표면 처리층이 제거되어 내식성이 감소하며, 상기와 같이 내식성이 감소한 브레이크 디스크의 제동면에 환경 조건(강우량, 온도, 습도 등)에 의하여 수분이 형성될 경우 부식이 다시 발생하는 문제점이 있었다.However, in the conventional brake disk, the surface treatment layer formed on the brake surface of the brake disk is removed by brake braking to reduce corrosion resistance, and environmental conditions (rainfall, temperature, humidity, etc.) are applied to the brake disk of the brake disk having reduced corrosion resistance as described above. When moisture is formed by the corrosion there was a problem that occurs again.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 희생 양극 물질과 전기회로를 이용하여 브레이크 디스크의 부식을 방지하는 브레이크 디스크 부식 방지 구조를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a brake disk corrosion prevention structure to prevent corrosion of the brake disk using a sacrificial anode material and an electric circuit.

상기 희생 양극용 금속부재는 회주철로 주조되는 브레이크 디스크 보다 이온화경향이 큰 금속 계열로 이루어지는 것을 특징으로 한다.The sacrificial anode metal member is made of a metal series having a larger ionization tendency than a brake disc cast of gray cast iron.

이와 같이 본 발명은 희생 양극용 금속부재, 배터리 및 브레이크 디스크를 포함하여 브레이크 디스크 부식방지 구조를 구성함으로써 브레이크 디스크 대신 희생 양극용 금속부재가 희생 부식하게 되며, 이에 따라 브레이크 디스크의 부식을 방지할 수 있는 효과가 있다.As described above, the present invention constitutes a brake disc corrosion prevention structure including a sacrificial anode metal member, a battery, and a brake disc, thereby sacrificial corrosion of the sacrificial anode metal member instead of the brake disc, thereby preventing corrosion of the brake disc. It has an effect.

이하, 본 발명에 따른 브레이크 디스크 부식 방지 구조를 첨부된 도 1 내지 도 4를 참조하여 상세히 설명한다.Hereinafter, a brake disc corrosion protection structure according to the present invention will be described in detail with reference to FIGS. 1 to 4.

본 발명에 따른 브레이크 디스크 부식 방지 구조는 도 1 및 도 2에 도시된 바와 같이, 브레이크 디스크(100)와, 상기 브레이크 디스크(100)가 삽입되고 결합되는 휠(200)과, 상기 브레이크 디스크(100)와 휠(200) 사이에 구비되고 전위차를 이용하여 브레이크 디스크의 부식을 방지하는 희생 양극용 금속수단(300)을 포함한다.As shown in FIGS. 1 and 2, the brake disc corrosion prevention structure according to the present invention includes a brake disc 100, a wheel 200 into which the brake disc 100 is inserted and coupled, and the brake disc 100. And the sacrificial anode metal means 300 provided between the wheel 200 and the corrosion of the brake disc by using the potential difference.

상기 브레이크 디스크(brake disc)(100)는 바퀴와 함께 회전하며, 양쪽에 브레이크 패드를 압착시켜 제동하는 장치로, 원판형상을 가진다.The brake disc 100 rotates together with the wheels and is a device for pressing and braking the brake pads on both sides thereof, and has a disc shape.

즉, 상기 브레이크 디스크(100)는 브레이크 페달(미도시)을 밟으면 마스터 실린더(미도시) 내부에서 유압이 발생하고, 상기 실린더에 유압이 작동하면 피스톤이 움직여 브레이크 디스크(100)의 제동면(110)에 패드(미도시)를 압착시킴에 따라 발생하는 마찰력을 통해 제동력을 발생시킨다.That is, the brake disc 100 generates hydraulic pressure inside the master cylinder (not shown) by stepping on the brake pedal (not shown), and when the hydraulic pressure is actuated on the cylinder, the piston moves to brake the surface 110 of the brake disc 100. ) To generate a braking force through the friction force generated by pressing the pad (not shown).

상기 휠(200)은 타이어와 함께 노면으로부터의 충격을 흡수하며 자동차의 방향을 전환하고 구동력과 제동력을 전달하는 역할을 하는 것으로, 외주면에는 타이어가 결합되고, 내부에는 다수의 볼트를 이용하여 상기 브레이크 디스크(100)가 삽입되고 결합되며, 중앙에는 구멍(210)이 형성된다.The wheel 200 absorbs the impact from the road surface along with the tire, and serves to change the direction of the vehicle and transmit driving and braking force. A tire is coupled to an outer circumferential surface thereof and the brake is formed by using a plurality of bolts therein. The disk 100 is inserted and coupled, and a hole 210 is formed in the center.

한편, 본 발명의 브레이크 디스크(100)는 제동시 브레이크 디스크(100)의 제동면(110)과 패드의 마찰력에 의해 상기 제동면(110)에 코팅된 코팅층(미도시)이 제거되면서 상기 제동면(110)에 부식이 발생하는 문제점이 있다.On the other hand, the brake disk 100 of the present invention, the braking surface 110 and the coating layer (not shown) coated on the braking surface 110 by the frictional force of the pad during the braking disk 100, the braking surface is removed There is a problem in that corrosion occurs 110.

이를 방지하기 위해 본 발명은 브레이크 디스크(100)와 휠(200) 사이에 희생 양극용 금속수단(300)을 구비함으로써 브레이크 디스크(100)와 희생 양극용 금속수단(300) 사이의 전위차를 발생시켜 브레이크 디스크(100)의 부식을 방지한다.In order to prevent this, the present invention includes the sacrificial anode metal means 300 between the brake disc 100 and the wheel 200 to generate a potential difference between the brake disc 100 and the sacrificial anode metal means 300. To prevent corrosion of the brake disc 100.

한편, 희생양극은 피방식 금속에 보다 저전위의 금속,예를 들면 철에는 알루미늄,마그네슘,아연 등의 양극을 전기적으로 연결하여 양 금속간의 국부전지 작용으로 발생하는 전류를 방식전류로 이용하는 방식이다. 이러한 경우 저전위 금속(희생양극)으로부터는 전류와 더불어 금속이온이 유출되면서,시간 경과에 따라 소모된다. 즉. 양극이 된 금속 대신 희생 부식하면서 피방식체의 부식을 방지하는 것이다.On the other hand, the sacrificial anode is a method of using a current generated by the local battery between the two metals as an anticorrosive current by electrically connecting a positive electrode such as aluminum, magnesium, zinc to a lower potential metal, such as iron, to the metal to be corroded. . In this case, metal ions flow out from the low potential metal (sacrificial anode) and are consumed over time. In other words. It is to prevent corrosion of the object by sacrificial corrosion instead of the anode metal.

그러나 양 금속만으로는 일정한 희생 부식을 유도할 수 없어, 양 금속간에 전류를 일정하게 흘러줌으로써 일정한 희생 부식을 유도할 수 있다.However, both metals alone cannot induce constant sacrificial corrosion, and thus constant sacrificial corrosion can be induced by a constant current flow between the two metals.

이와 같은 희생양극은 산업현장에서 널리 사용되는 공지된 기술로, 그에 따 라 자세한 설명은 생략한다.Such sacrificial anodes are well-known techniques widely used in industrial sites, and thus detailed descriptions thereof will be omitted.

즉, 본 발명의 상기 희생 양극용 금속수단(300)은 휠(200)의 구멍(210)에 삽입 고정되는 희생 양극용 금속부재(310)와, 상기 브레이크 디스크(100) 및 희생 양극용 금속부재(310) 사이에 구비되고 브레이크 디스크(100) 및 희생 양극용 금속부재(310)를 전류가 흐를 수 있도록 연결하는 배터리(320)를 포함한다.That is, the sacrificial anode metal means 300 of the present invention includes a sacrificial anode metal member 310 inserted into and fixed to the hole 210 of the wheel 200, and the brake disc 100 and the sacrificial anode metal member. It is provided between the 310 and includes a battery 320 for connecting the brake disk 100 and the sacrificial anode metal member 310 so that current can flow.

다시 말해, 도 4에 도시된 바와 같이, 상기 배터리(320)의 +극은 희생 양극용 금속부재(310)에 전류가 흐를 수 있도록 연결하고, -극은 브레이크 디스크(100)에 전류가 흐를 수 있도록 연결한다.In other words, as shown in FIG. 4, the positive electrode of the battery 320 may be connected to the sacrificial anode metal member 310 so that a current may flow, and the negative pole may flow a current to the brake disc 100. Connect it so that

따라서 상기 희생 양극용 금속수단(300)은 배터리(320)을 통해 브레이크 디스크(100)에서 희생 양극용 금속부재(310)로 전류가 흐르도록 구성함으로써 희생 양극용 금속부재(310)와 브레이크 디스크(100) 사이에 전위차가 발생하며, 이에 따라 브레이크 디스크(100)에 발생하는 부식을 희생 양극용 금속부재(310)가 대신하여 희생 부식을 하게 된다.Therefore, the sacrificial anode metal member 300 is configured such that a current flows from the brake disc 100 to the sacrificial anode metal member 310 through the battery 320, thereby providing the sacrificial anode metal member 310 and the brake disc ( A potential difference is generated between the 100 and, thus, the sacrificial anode metal member 310 replaces the corrosion generated in the brake disc 100 with the sacrificial corrosion.

여기서, 상기 희생 양극용 금속부재(310)는 브레이크 디스크(100)를 대신하여 희생 부식하기 위해 회주철로 주조되는 브레이크 디스크(100) 보다 이온화 경향이 큰 금속 계열로 이루어진다. Here, the sacrificial anode metal member 310 is made of a metal series having a greater tendency of ionization than the brake disc 100 cast with gray cast iron to sacrificially corrode in place of the brake disc 100.

바람직하게는 상기 희생 양극용 금속부재(310)는 납, 칼륨, 나트륨, 마그네슘, 및 알루미늄 계열 중 하나의 금속 계열을 사용하여 조성되며, 더욱 바람직하게는 상기 희생 양극용 금속부재(310)는 도 3에 도시된 바와 같이, 은(Ag)이 2.0%~5.0%, 안티몬(Sb)이 4.5%~7.5%, 및 납(Pb)이 87.5%~93.5%로 조성된다.Preferably, the sacrificial anode metal member 310 is formed using one metal series of lead, potassium, sodium, magnesium, and aluminum series, and more preferably, the sacrificial anode metal member 310 is illustrated in FIG. As shown in 3, silver (Ag) is 2.0% to 5.0%, antimony (Sb) is 4.5% to 7.5%, and lead (Pb) is composed of 87.5% to 93.5%.

즉, 본 발명의 브레이크 디스크(100)는 회주철로 주조되기 때문에, 상기 브레이크 디스크(100) 보다 이온화 경향이 큰 저전위인 금속인 납이 87.5%~93.5% 포함된 납 계열의 희생 양극용 금속부재(310)를 사용하는 것이 바람직하다.That is, since the brake disc 100 of the present invention is cast from gray cast iron, a lead-based sacrificial anode metal member containing 87.5% to 93.5% of lead, which is a low potential metal having a larger ionization tendency than the brake disc 100 ( 310) is preferred.

따라서 상기 희생 양극용 금속수단(300)은 도 4에 도시된 바와 같이 배터리(320)를 통해 브레이크 디스크(100)와 희생 양극용 금속부재(310) 사이에 전류가 흐르게 되어 브레이크 디스크(100)와 희생 양극용 금속부재(310) 사이에 전위차가 발생함으로써 브레이크 디스크(100)의 부식을 희생 양극용 금속부재(310)가 대신 희생 부식하게 된다.Accordingly, as shown in FIG. 4, the sacrificial anode metal means 300 has a current flowing between the brake disc 100 and the sacrificial anode metal member 310 through the battery 320, thereby providing the brake disc 100 with the brake disc 100. As a potential difference occurs between the sacrificial anode metal members 310, the sacrificial anode metal member 310 sacrificially erodes the corrosion of the brake disc 100.
