본 고안은 자동차의 브레이크패드 고정용 백플레이트 설치구조에 관한 것으로, 특히 캘리퍼의 구성 부품인 캐리어의 요입부에는 고정홈과 안내홈을 형성하는 동시에 백플레이트의 양측단에는 고정돌기와 삽지부를 일체로 형성하므로써, 제동시 디스크의 회전 방향으로 백플레이트가 치우치는 현상에 의해 제동토크가 집중되어 소음 및 이상진동 발생을 예방하여 정상적인 제동력을 유지할 수 있게 된 자동차의 브레이크패드 고정용 백플레이트 설치구조에 관한 것이다.The present invention relates to a back plate mounting structure for fixing a brake pad of an automobile, and in particular, a fixing groove and a guide groove are formed in a recess of a carrier, which is a component of a caliper, and at the both ends of the back plate, the fixing protrusion and the inserting portion are integrally formed. The present invention relates to a brake pad fixing structure for fixing a brake pad of a vehicle in which a braking torque is concentrated due to a phenomenon in which the back plate is biased in the rotational direction of the disk during braking, thereby preventing noise and abnormal vibrations from occurring. .

일반적으로 디스크 브레이크(Disc brake)는 드럼 대신에 바퀴와 함께 회전하도록 된 디스크를 유압에 의하여 작동하는 패드로써 양쪽에서 압착하여 마찰력으로 제동하는 브레이크이다.In general, a disc brake (Disc brake) is a pad that is operated by a hydraulic pressure to the disk that is to rotate with the wheel instead of the drum is a brake that is squeezed on both sides by the friction force.

이러한 디스크 브레이크는 특수 주철로 만들며 휘일 허브에 결합되어 바퀴와 함께 회전하는 디스크(Disc)와, 특수 주철로 된 안장 모양이며 지지 브래킷과 너클 스핀들 사이에는 디스크와 중심을 맞추기 위한 심(Shim)과 양쪽면에 브레이크 실린더가 설치된 캘리퍼(Caliper)와, 그 캘리퍼의 외부에 2개가 결합되어 있는 브레이크 실린더와, 보통 석면과 수지를 혼합 소성한 것으로 뒷면에는 얇은 금속판으로 된 백플레이트가 결합된 브레이크패드(Break pad)와, 그 밖에 시일 및 실린더 안에 물이나 먼지가 침입하는 것을 방지하는 실린더 부우트(Cylinder boots)가 설치되어 있다.These disc brakes are made of special cast iron and are coupled to wheel hubs to rotate with the wheels (Disc), saddle shaped with special cast iron and between the support bracket and the knuckle spindle shim and both sides to center the disk. A brake pad with a brake cylinder installed on the surface, a brake cylinder with two bonded to the outside of the caliper, and a combination of plastic and plastic asbestos and resin, and a back plate made of a thin metal plate on the back. pad) and other cylinder boots that prevent water or dust from entering the seal and the cylinder.

한편 상기 브레이크패드가 부설된 백플레이트의 설치구조에 있어, 종래에는 도면 도 3에 도시된 바와같이 디스크(10)의 일측면에 위치하고 너클(도면에 미도시)에 고정 설치된 캘리퍼(20)는 하우징(Housing)(도면에 미도시)과 캐리어(Carrier)(22)로 구분 형성되어 있으며, 그 캐리어(22)의 일측에는 삽지홈(26)이 양측벽으로 형성된 요입부(24)를 형성하고 있으며, 그 요입부(24)에 안착된 다음 삽지홈(26)에 끼워 고정되도록 상기 백플레이트(30)의 양단에는 삽지돌기(32)를 각각 형성하고 있었다.Meanwhile, in the installation structure of the back plate on which the brake pad is installed, the caliper 20 is conventionally located on one side of the disk 10 and fixed to a knuckle (not shown) as shown in FIG. 3. (Housing) (not shown in the figure) and the carrier (Carrier) 22 is formed separately, one side of the carrier 22, the insertion grooves 26 are formed in the recessed portion 24 formed with both side walls. Inserting protrusions 32 were formed at both ends of the back plate 30 so as to be seated in the recess 24 and then inserted into the inserting groove 26.

이렇게 된 종래의 기술에서는 차량의 주행시 기관의 회전력은 바퀴와 함께 상기 디스크(10)를 회전시키게 된다. 이때 상기 캐리어(22)의 요입부(24)에는 백플레이트(30)가 설치되어 있는 데, 그 백플레이트(30)의 삽지돌기(32)는 요입부(24)의 삽지홈(26)에 끼워져 요동이 가능한 상태로 되어 있었다. 그렇지만 이 같은 상태에서는 차량의 주행도중 노면의 상태에 따라 차량의 진동 발생시 상기 백플레이트(30)도 함께 요동하거나, 도면에서처럼 재료내의 서로 접근한 두 평행면에 크기는 같으나 반대 방향으로 작용하는 힘인 전단력(前斷力)에 의해 상기 디스크(10)의 회전 방향으로 백플레이트(30)가 쏠리는 현상이 발생하게 되었다. 이에 따라 제동시 밸플레이트(30)의 일단으로만 제동토크가 발생하게 되어 브레이크패드의 편마모 및 이상마모가 발생하여 소음, 이상진동(Judder) 등이 발생하므로 정상적인 제동력을 얻을 수 없는 등의 문제점이 있었다.In the related art, the rotational force of the engine during the driving of the vehicle rotates the disk 10 together with the wheels. At this time, the back plate 30 is provided in the recess portion 24 of the carrier 22, the insertion protrusion 32 of the back plate 30 is fitted into the insertion groove 26 of the recess portion 24 The swinging was possible. However, in such a state, the back plate 30 also swings together when the vehicle vibrates according to the road surface during driving of the vehicle, or as shown in the drawing, the shear force, which is a force acting in the opposite direction but the same magnitude in two parallel surfaces approaching each other in the material ( The phenomenon in which the back plate 30 is inclined in the rotational direction of the disk 10 due to the front force occurs. Accordingly, when braking, the braking torque is generated only at one end of the ball plate 30, and the brake pad is subjected to uneven wear and abnormal wear, which causes noise, abnormal vibration, etc., and thus, normal braking force cannot be obtained. there was.

본 고안의 기술적 과제는 제동시 디스크의 회전 방향에 따른 제동토크를 방지시켜 백플레이트가 일측 부위로 치우치는 현상을 방지하므로써 백플레이트의 요동이 발생되는 것을 방지하여 소음 및 이상진동을 예방함에 따라 정상적인 제동력을 발휘할 수 있게 된 자동차의 브레이크패드 고정용 백플레이트 설치구조를 제공하는 데 있다.The technical problem of the present invention is to prevent braking torque according to the rotational direction of the disk during braking, thereby preventing the backplate from shifting to one side, thereby preventing the backplate from occurring, thus preventing normal noise and abnormal vibration. The present invention provides a back plate mounting structure for fixing a brake pad of a vehicle that can be used.

이러한 본 고안은 디스크 일측면에 위치하도록 설치된 캘리퍼의 캐리어에는 요입부를 형성하고, 그 요입부에 안착되어 슬라이딩 가능하게 설치한 자동차의 브레이크패드 고정용 백플레이트에 있어서, 상기 캐리 어의 요입부 양측벽의 안내홈을 내측으로 굴곡 연장시켜 고정홈을 형성하고, 그 고정홈에 끼워 빠지지 않도록 상기 백플레이트의 양측단에는 선단에 고정돌기가 형성된 삽지부를 일체로 형성하므로써 달성되는 것이다.The present invention is to provide a recess in the carrier of the caliper installed to be located on one side of the disk, the brake pad fixing back plate of the car installed in the recess to be slidably installed, both side walls of the recess of the carrier It is achieved by bending the guide groove of the inner side to form a fixing groove, integrally forming an insertion portion formed with a fixing projection at the front end at both ends of the back plate so as not to be inserted into the fixing groove.

그 요입부(124)에 안착되어 슬라이딩 가능하게 브레이크패드 고정용 백플레이트를 설치하되 상기 캐리어(122)의 요입부(124) 양측벽의 안내홈(126)을 내측으로 굴곡 연장시켜 고정홈(128)을 형성한다.The brake pad fixing back plate is installed on the concave inlet 124 so as to be slidable, but the guide grooves 126 of both side walls of the concave inlet 124 of the carrier 122 are bent to extend inward to fix the fixing groove 128. ).

그 안내홈(126)에 끼워 빠지지 않도록 상기 백플레이트(130)의 양측단에는 선단에 고정돌기(134)가 형성된 삽지부(132)를 일체로 형성하여 된 것이다.In order to prevent the guide groove 126 from being inserted into the back plate 130, insertion portions 132 having fixed protrusions 134 formed on the front end are formed integrally.

이와같이 구성된 본 고안의 작용을 상세히 설명한다.The operation of the present invention configured as described above will be described in detail.

이와 같은 구성으로 된 본 고안은 캘리퍼(120)의 캐리어(122)에 형성된 요입부(124)로 브레이크패드가 설치되어 제동력을 얻을 수 있도록 한 것인 데, 주행시에는 회전하게 된 디스크의 회전 방향으로 치우쳐 제동토크가 발생하는 현상을 백플레이트(130)의 양측단에 형성한 삽지부(132)를 캐리어(122)에 형성한 안내홈(126)에 끼워 고정되게 하여 이상진동이나 소음의 발생을 방지하게 된 것이다.The present invention having such a configuration is to provide a brake pad to the concave inlet 124 formed on the carrier 122 of the caliper 120 to obtain a braking force, in the direction of rotation of the disk rotated when running The occurrence of the bias braking torque is inserted into the guide grooves 126 formed on the carrier 122 by fixing the insertion portions 132 formed at both ends of the back plate 130 to prevent abnormal vibration or noise. It is done.

즉, 상기 캐리어(122)의 요입부(124) 양측벽에는 안내홈(126)을 각각 형성하게 되고, 그 안내홈(126)을 연장하여 고정홈(128)이 형성된다. 그리고 백플레이트(130)의 양단에는 삽지부(132)를 형성하되 그 삽지부(132)의 선단에는 고정돌기(134)를 일체로 절곡 형성하게 된다. 이후 상기 백플레이트(130)를 캐리어(122)의 요입부(124)에 설치할 경우 백플레이트(130)의 삽지부(132)가 캐리어(122)의 안내홈(126)에 끼워지면서, 삽지부(132)의 고정돌기(134)가 안내홈(126)의 고정홈(128)으로 끼워 움직이지 않게 되는 것이다.That is, guide grooves 126 are formed on both side walls of the recessed portion 124 of the carrier 122, and the guide grooves 126 extend to form the fixing grooves 128. And the inserting portion 132 is formed at both ends of the back plate 130, but the fixing projections 134 are integrally bent at the tip of the inserting portion 132. Since the back plate 130 is installed in the recess 124 of the carrier 122, the inserting portion 132 of the back plate 130 is inserted into the guide groove 126 of the carrier 122, the inserting portion ( The fixing protrusion 134 of the 132 is inserted into the fixing groove 128 of the guide groove 126 is not moved.
