디스크 브레이크 캘리퍼의 채터링 방지장치Chattering prevention device of disc brake caliper

본 고안은 자동차 디스크 브레이크에 관한 것으로 보다 상세하게는 바퀴와 함께 회전하는 브레이크 디스크의 양쪽에서 제동 패드를 유압에 의해 눌러서 제동 하도록 하는 형식의 캘리퍼형 디스크 디스크 브레이크에 있어서 캘리퍼 고정 구조에 관한 것이다.The present invention relates to an automobile disc brake, and more particularly, to a caliper fixing structure in a caliper-type disc disc brake of a type in which a brake pad is pressed by hydraulic pressure on both sides of a brake disc rotating with a wheel.

캘리퍼형 디스크 브레이크는 대향 피스턴 고정 캘리퍼형, 싱글 실린더 플로팅 캘리퍼형이 있고,어느 것이나 디스크, 캘리퍼, 브레이크 실린더 및 피스턴, 자동틈새 조정장치등을 갖추고 있다.The caliper disc brakes have opposing piston fixed calipers, single cylinder floating calipers, and are equipped with discs, calipers, brake cylinders and pistons, and automatic clearance adjustment.

이러한 종래 디스크 브레이크는 제1도와 같이 마스터 실린더측으로 부터 유압을 받는 브레이크 파이프 홈, 피스턴, 피스턴 시일, 실린더, 캘리퍼등이 있고,바퀴와 같이 회전하는 디스크(1), 상기 디스크(1)에 접촉되어 디스크를 제동하는 캘리퍼(2), 캘리퍼(2)에 수용되어 디스크(1)를 마찰력으로 제동하는 패드등으로 구성되어 캘리퍼 브라켓(3)에 의해 조향 너클(4)측에 결합된다.The conventional disc brake includes a brake pipe groove, piston, piston seal, cylinder, caliper, etc., which receive hydraulic pressure from the master cylinder side as shown in FIG. 1, and is in contact with the disc 1 rotating like a wheel and the disc 1 It consists of a caliper 2 for braking the disc, a pad accommodated in the caliper 2, and a pad for braking the disc 1 with a frictional force, and is coupled to the steering knuckle 4 side by the caliper bracket 3.

조향 너클(4)측에 대한 캘리퍼(2) 결합 구조는 제2도와 같이 캘리퍼 브라켓(3)을 통해 조향 너클(4)에 장착되는데, 캘리퍼 브라켓(3)은 조향 너클(4)측에 마운팅 볼트(5)에 의해 직접 고정된다.The caliper 2 coupling structure on the steering knuckle 4 side is mounted to the steering knuckle 4 via the caliper bracket 3 as shown in FIG. 2, with the caliper bracket 3 mounting bolts on the steering knuckle 4 side. It is directly fixed by (5).

이를 위하여 캘리퍼 브라켓(3)에는 조향 너클(4)측 설치환경에 맞춘 볼트 안내홈(6)을 상, 하부에 밸런스를 유지시켜 형성하고, 조향 너클(4)측에는 상기 캐리어(3)의 볼트 안내홈(6)과 일치되는 캐리어 고정용 마운팅 홀(7)을 형성하여 마운팅 볼트(5)를 사용하여 고정한다.To this end, the caliper bracket (3) is formed by balancing the bolt guide groove (6) in accordance with the installation environment on the steering knuckle (4) side, upper and lower, and the bolt guide of the carrier (3) on the steering knuckle (4) side A mounting hole 7 for fixing the carrier is formed to coincide with the groove 6 and fixed using the mounting bolt 5.

따라서 캐리어 브라켓(3)은 조향 너클(4)에 고정된 상태를 유지하고 캘리퍼(2)상의 실린더 보디(8)가 좌, 우측으로 움직여 브레이크 디스크(1)를 잡아주는 설치 형태를 갖게되지만 이때, 브레이크 디스크(1)를 마찰력으로 잡아주는 동적 움직임에 의해 캘리퍼(2)측에는 회전 모멘트가 발생하여 캘리퍼 브라켓(3)의 마운팅 부분에 떨림 현상이 나타나고, 채터링 발생 소지가 있으며, 이는 제동 안정성에 영향을 미치는 것으로 나타났다.Therefore, the carrier bracket 3 is fixed to the steering knuckle 4 and has an installation form in which the cylinder body 8 on the caliper 2 moves left and right to hold the brake disc 1. Due to the dynamic movement that holds the brake disc 1 with friction, rotation moment is generated on the side of the caliper 2, causing a shaking phenomenon in the mounting portion of the caliper bracket 3, which may cause chattering, which affects the braking stability. Appeared to affect.

본 고안은 디스크 브레이크에서 제동시 캘리퍼에서 생기는 회전 모멘트에 의한 캘리퍼의 진동을 억제시키고, 채터링 발생 가능성을 낮춰주는 것이다.The present invention is to suppress the vibration of the caliper due to the rotation moment generated in the caliper when braking in the disc brake, and to reduce the possibility of chattering.

본 고안은 바퀴와 같이 회전하는 디스크, 디스크에 접촉되어 디스크를 제동하는 캘리퍼, 캘리퍼를 캘리퍼 브라켓에 의해 조향너클측에 결합하는 디스크 브레이크 캘리퍼 장착 구조에 있어서, 제5도와 같이 캘리퍼(2)를 조향 너클(4)측에 장착하기 위해 캘리퍼 브라켓(3a)측에 형성된 볼트 안내홈(6a)에 쿠션 패드(10)를삽입시켜 구성한다.The present invention is a disc that rotates like a wheel, a caliper for contacting the disc to brake the disc, and a disc brake caliper mounting structure for coupling the caliper to the steering knuckle side by a caliper bracket, steering the caliper 2 as shown in FIG. The cushion pad 10 is inserted into the bolt guide groove 6a formed on the caliper bracket 3a side for mounting on the knuckle 4 side.

이렇게 볼트 안내홈(6a)에 쿠션 패드(10)를 삽입한 캘리퍼 브라켓(3a)은, 조향 너클(4)에 대한 캘리퍼(2) 장착의 경우 캘리퍼 브라켓(3a)의 볼트 안내홈(6a)을 관통하는 고정용 볼트(5a)의 외경과 쿠션 패드(10)가 직접 접촉되면서 캘리퍼(2)를 조향 너클(4)에 장착 시킨다.The caliper bracket 3a in which the cushion pad 10 is inserted into the bolt guide groove 6a in this way is, when the caliper 2 is attached to the steering knuckle 4, the bolt guide groove 6a of the caliper bracket 3a. As the outer diameter of the fixing bolt 5a penetrating and the cushion pad 10 come into direct contact with each other, the caliper 2 is mounted on the steering knuckle 4.

한편, 제동시 실린더 보디측에서 디스크를 잡아주는데, 이러한 제동 단계에서 캘리퍼(2)가 좌,우로 유동 되면서 캘리퍼측에 회전 모멘트를 형성 시키고, 이 회전 모멘트에 의해 캘리퍼(2)를 고정하는 캘리퍼 브라켓(3a)의 지지점인 고정용 볼트(5a)에는 방향성 부하가 작용되면서 캘리퍼 브라켓(3a)의 지지점이 되는 부분에는 진동이 발생된다.On the other hand, when braking, the disc is held by the cylinder body side. In this braking step, the caliper 2 flows to the left and right to form a rotation moment on the caliper side, and the caliper bracket fixes the caliper 2 by the rotation moment. While the directional load is applied to the fixing bolt 5a, which is the support point of 3a, vibration is generated at the portion that becomes the support point of the caliper bracket 3a.

이때, 캘리퍼 브라켓(3a)의 지지점이 되는 고정용 볼트(5a)와 면 접촉되는 캘리퍼 브라켓(3a)측 볼트 안내홈(6a)에 끼워진 쿠션 패드(10)는 고정용 볼트(6a)를 통해 전가되는 진동을 흡수하고, 완충 시킨다.At this time, the cushion pad 10 fitted in the caliper bracket 3a side bolt guide groove 6a which is in surface contact with the fixing bolt 5a serving as the support point of the caliper bracket 3a is transferred through the fixing bolt 6a. Absorbs and cushions vibrations.

본 고안은 캘리퍼 브라켓측 볼트 안내홈에 끼워지고, 이를 관통하여 조향 너클측에 결합되는 고정용 볼트의 외경측과 캘리퍼 브라켓의 볼트 안내홈과의 직접 접촉을 피하고, 그 사이에 완충단면을 형성 함으로서 제동시 캘리퍼를 통해 전달되는 회전 모멘트에 의한 진동을 완화 시켜 채터링 발생 가능성을 줄여, 제동 안정성을 높혀주는데 기여한다.The present invention fits into the caliper bracket side bolt guide groove, avoids direct contact between the outer diameter side of the fixing bolt coupled to the steering knuckle side and the bolt guide groove of the caliper bracket, and forms a cushioning section therebetween. It reduces vibrations caused by the rotation moment transmitted through the caliper during braking, reducing the possibility of chattering and contributing to enhancing braking stability.

본 고안은 스티어링 너클측에 장착 고정되는 디스크 브레이크 캘리퍼의 진동을 줄이고 채터링(CHATTERING) 현상을 억제 하여 제동 안정성을 좋게 하는 것이다.The present invention is to improve the braking stability by reducing the vibration of the disc brake caliper mounted on the steering knuckle side and suppressing chattering phenomenon.
