Abstract

A vehicle disk brake is provided to prevent cooling performance from deteriorating during braking by increasing a contact area between a brake pad and a brake disk. A vehicle disk brake comprises a brake disk(200) inserted into an inner side of a caliper, a pair of brake pads(300) and a piston. The brake pads are installed at two sides of the brake disk while being spaced apart from each other by a certain interval. The piston pressures the brake pads toward the brake disk. Auxiliary disk brakes(210) are formed at the outer portions of two sides of the brake disk while being spaced apart from each other by a certain interval. The brake pads make contact with the outer surfaces of the auxiliary disk brakes and the brake disk. The brake pads are formed with insertion grooves(310) into which the auxiliary disk brakes are inserted respectively.

본 발명은 자동차의 디스크브레이크에 관한 것으로서, 더욱더 상세하게는 브레이크디스크와 브레이크 패드의 마찰면적이 증대되어 제동력이 향상되도록 하는 자동차의 디스크브레이크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake of a motor vehicle, and more particularly, to a disc brake of a motor vehicle, in which a friction area between a brake disc and a brake pad is increased to improve a braking force.

일반적으로 자동차의 브레이크로는 디스크타입 브레이크와 드럼타입 브레이크가 많이 사용되고 있다. (이하 디스크타입 브레이크는 디스크브레이크로, 드럼타입 브레이크는 드럼브레이크로 칭한다.)In general, as a brake of a car, a disk type brake and a drum type brake are used. (Hereinafter, the disc type brake is called a disc brake, and the drum type brake is called a drum brake.)

상기 디스크브레이크는 도 1에 도시하고 있는 바와 같이 캘리퍼(100)의 내측에 삽입되어 있는 브레이크디스크(200)의 좌우 양측에 소정의 간격을 두고 한 쌍의 브레이크패드(300)가 설치되고, 상기 브레이크패드(300)를 브레이크디스크(200)에 가압시키는 피스톤(400)이 캘리퍼(100)의 내측에 내장되는 구조로 이루어져 있다.As shown in FIG. 1, a pair of brake pads 300 are installed at left and right sides of the brake disc 200 inserted into the caliper 100 at predetermined intervals, as shown in FIG. 1. Piston 400 for pressing the pad 300 to the brake disc 200 is made of a structure that is built in the interior of the caliper (100).

따라서, 차량을 운행 시 운전자가 브레이크폐달을 밟음으로써 발생한 제동유압이 최종적으로 상기 피스톤(400)에 작용하여 이 피스톤(400)이 브레이크패드(300)를 브레이크디스크(200)에 밀어붙임으로써 마찰에 의한 제동 작용이 일어나도록 되어 있다.Therefore, the braking hydraulic pressure generated when the driver presses the brake pedal during driving of the vehicle finally acts on the piston 400, and the piston 400 pushes the brake pad 300 to the brake disc 200 to prevent friction. By the braking action.

그러나, 이러한 종래 자동차의 디스크브레이크는 반응은 빠르나 드럼브레이크보다 제동력이 약하다는 단점이 있었다.However, such a disc brake of a conventional vehicle has a disadvantage in that the reaction is fast but the braking force is weaker than that of the drum brake.

따라서, 종래에도 상기와 같은 문제점을 해결하기 위해 브레이크디스크와 브레이크패드 사이의 마찰계수가 커지도록 브레이크패드(300)의 면적을 증대시키기도 하였다.Therefore, in order to solve the above problems, the area of the brake pad 300 has also been increased to increase the coefficient of friction between the brake disc and the brake pad.

그러나 상기와 같이 브레이크패드(300)의 면적을 증대시키는 경우에는 냉각이 제대로 이루어지지 않아 제동력이 저하되어지게 되는 문제점이 있었다.However, in the case of increasing the area of the brake pad 300 as described above, there is a problem that the braking force is lowered due to poor cooling.

본 발명의 목적은 브레이크패드와 브레이크디스크를 다판으로 구성하여, 제동을 수행 시 브레이크패드와 브레이크디스크의 접촉 면적이 증대되도록 함으로써 브레이크 작동시 제동력이 증대되도록 하는 자동차의 디스크브레이크를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a disc brake of an automobile, in which a brake pad and a brake disc are formed of multiple plates so that the contact area between the brake pad and the brake disc is increased when braking is performed, thereby increasing the braking force during brake operation.

상기한 바와 같은 목적을 달성하기 위하여, 본 발명은 캘리퍼(100)의 내측에 삽입되어 있는 브레이크디스크(200)의 좌우 양측에 소정의 간격을 두고 한 쌍의 브레이크패드(300)가 설치되고, 상기 브레이크패드(300)를 브레이크디스크(200)에 가압시키는 피스톤(400)이 캘리퍼(100)의 내측에 내장되는 것에 있어서, 상기 브레이크디스크(200)의 좌우 양측 외측부에 소정의 간격을 두고 보조디스크브레이크(210)가 각각 형성되고, 상기 보조디스크브레이크(210)와 브레이크디스크(200)의 외측면에 브레이크패드(300)가 접촉되도록 설치되는 것에 의해 달성된다. In order to achieve the above object, in the present invention, a pair of brake pads 300 are installed at left and right sides of the brake disc 200 inserted into the caliper 100 at predetermined intervals. When the piston 400 for pressing the brake pad 300 to the brake disc 200 is embedded inside the caliper 100, the auxiliary disc brake is spaced apart from the left and right sides of the brake disc 200 at predetermined intervals. 210 are formed respectively, and the brake pads 300 are installed to contact the outer side surfaces of the auxiliary disc brake 210 and the brake disc 200.

따라서, 차량을 운행하는 운전자가 정차 및 주차를 수행하기위해 브레이크폐달을 발로 밟으면 브레이크패드(300)가 보조디스크브레이크(210)의 외측면과 브레이크디스크(200 )의 외측면에 접촉되어 마찰되는 것에 의해 제동이 이루어지게 된 다.Therefore, when the driver who drives the vehicle presses the brake pedal to stop and park, the brake pad 300 is in contact with the outer surface of the auxiliary disk brake 210 and the outer surface of the brake disk 200 to be rubbed. Braking is achieved.

본 발명인 자동차의 디스크브레이크는 도 3과 도 4 및 도 5에 도시하고 있는 바와 같이 브레이크디스크(200)의 외측면에 접촉되는 접촉면이 소정거리 이격된 상태의 브레이크패드(300)와, 상기 브레이크패드(300)를 브레이크디스크(200)로 밀어붙이는 피스톤(400)을 구비한 디스크브레이크에 있어서, 상기 브레이크디스크(200)의 좌우 양측 외측부에 소정의 간격을 두고 보조디스크브레이크(210)가 각각 형성되고, 상기 보조디스크브레이크(210)의 외측 단부를 감싸며 외측면이 브레이크디스크(200)에 접촉되도록 브레이크패드(300)가 설치된다.Disc brake of the present invention vehicle as shown in Figures 3, 4 and 5 and the brake pad 300, the contact surface which is in contact with the outer surface of the brake disc 200 spaced a predetermined distance and the brake pad In the disc brake having a piston 400 for pushing the 300 to the brake disc 200, the auxiliary disc brakes 210 are formed at left and right sides of the brake disc 200 at predetermined intervals, respectively. The brake pad 300 is installed to surround the outer end of the auxiliary disk brake 210 and the outer surface contacts the brake disk 200.

물론, 상기 브레이크패드는(300) 도 4와 도 5 및 도 6에 도시하고 있는 바와 같이 보조디스크브레이크(210)가 삽입되는 삽입홈(310)이 내삽지게 중앙부에 형성되어 있어, 상기 브레이크패드(300)의 삽입홈(310)에 보조디스크브레이크(210)를 삽입시켜주는 것에 의해 브레이크패드(300)와 보조디스크브레이크(210)에 브레이크패드(200)가 접촉되어 마찰될 수 있도록 설치된 상태를 유지하게 된다.Of course, the brake pad 300 has an insertion groove 310 into which the auxiliary disc brake 210 is inserted, as shown in FIGS. By inserting the auxiliary disk brake 210 into the insertion groove 310 of the 300, the brake pad 300 and the auxiliary disk brake 210 is maintained in a state in which the brake pad 200 is contacted and rubbed. Done.

이와 같이 구성되는 본 발명은 차량을 운행 중 운전자가 브레이크폐달을 발로 밟으면 제동유압을 전달받는 피스톤(400)이 작동되면서 브레이크패드(300)를 밀게 된다.The present invention configured as described above pushes the brake pad 300 while the piston 400 receiving the braking hydraulic pressure is operated when the driver steps on the brake pedal while driving the vehicle.

이때, 상기 브레이크패드(300)의 외 측면은 브레이크디스크(200)의 외측면에 접촉되고, 상기 브레이크패드(300)의 삽입홈(310) 일측 벽면은 보조디스크브레이크(210)의 외측면)에 접촉되면서 마찰력을 발생시키게 된다.At this time, the outer side of the brake pad 300 is in contact with the outer surface of the brake disc 200, one side wall surface of the insertion groove 310 of the brake pad 300 to the outer surface of the auxiliary disk brake 210) The contact causes frictional force.

즉, 브레이크가 작동할 때 브레이크패드(300)의 외측면과 삽입홈(310)의 일측 벽면이 브레이크디스크(200) 및 보조디스크브레이크(210)의 외측면에 각각 접촉되는 것에 의해 마찰면적이 증대되어지게 됨으로써, 차량의 제동력이 증가되어지게 되는 것이다.That is, the friction area is increased by contacting the outer surface of the brake pad 300 and the one side wall of the insertion groove 310 with the outer surface of the brake disk 200 and the auxiliary disk brake 210 when the brake is operated. By doing so, the braking force of the vehicle is increased.

따라서, 본 발명은 차량을 운행 중 제동 등을 수행하는 경우 브레이크패드의 외측면과 삽입홈의 일측 벽면이 브레이크디스크의 측면 및 보조디스크브레이크의 외측면에 접촉되는 것에 의해 접촉면적이 2배로 넓어지게 됨으로써, 제동력이 향상되어지게 됨은 물론 브레이크패드의 많은 면적이 접촉되며 제동시에도 냉각성능이 저하되지 않도록 하는 등의 효과가 있다.Therefore, the present invention is to double the contact area by the outer surface of the brake pad and the one side wall of the insertion groove in contact with the side surface of the brake disk and the outer surface of the auxiliary disk brake when braking, etc. while driving the vehicle. As a result, the braking force is improved, and a large area of the brake pad is in contact with each other, and the cooling performance is not reduced even when braking.
