Description

차량용 브레이크캘리퍼의 복원력 보강구조Reinforcement structure of brake brake caliper for vehicle

본 고안은 차량에 구비되는 자동제동시스템용 브레이크캘리퍼의 복원력 보강구조에 관한 것으로, 특히 상기 브레이크캘리퍼를 이루는 피스톤측 캘리퍼바디의 내주면 결합요부에 끼워지는 리턴씰에 스프링부재를 구비하여 차량의 운전자가 브레이크페달을 밟았다 놓을 시 상기 캘리퍼바디의 피스톤이 신속히 원위치로 복귀될 수 있게 하도록 한 차량용 브레이크캘리퍼의 복원력 보강구조에 관한 것이다.The present invention relates to a restoring force reinforcing structure of a brake caliper for an automatic braking system provided in a vehicle, and in particular, a driver of a vehicle includes a spring member in a return seal fitted to an inner circumferential surface engaging portion of a piston-side caliper body forming the brake caliper. It relates to a restoring force reinforcing structure of a brake caliper for a vehicle that allows the piston of the caliper body to quickly return to its original position when the brake pedal is stepped on and released.

일반적으로, 차량은 제동시 감속속도에 따라 차량의 무게중심이 전방향으로 이동하여 앞바퀴의 하중은 증가하고 뒷바퀴의 하중은 감소하는 경향이 생기게 되는데 이때, 바퀴가 정지하여 스키드(Skid)현상을 일으키게 됨에 따라 바퀴와 노면과의 마찰력이 현저하게 감소하게 된다.In general, when the vehicle is braking, the center of gravity of the vehicle moves forward in accordance with the deceleration speed, so that the load of the front wheel increases and the load of the rear wheel tends to decrease. At this time, the wheel stops causing skid phenomenon. As a result, the friction between the wheel and the road surface is significantly reduced.

그에 따라서, 차량이 방향성을 잃게 되어 제동성능이 저하됨은 물론 궁극적으로 차량의 사고를 불러일으키게 된다.As a result, the vehicle loses its direction and thus the braking performance is deteriorated, and ultimately it causes an accident of the vehicle.

제1도에 도시된 바와 같이 차량은 앞 뒤, 좌우의 제동력을 균일하게 유지시키는 자동제동시스템(1)이 구비되는 바 상기 자동제동시스템(1)은 대별하여 브레이크페달(2), 마스터실린더(3), 프로포션닝밸브(4), 브레이크캘리퍼(5)로 이루어지는 바 상기 브레이크페달(2)은 운전자로 하여금 작은 힘으로도 커다란 가압력을 발생시킬 수 있게 하는 지렛대역할를 담당하게 된다.As shown in FIG. 1, the vehicle is provided with an automatic braking system 1 which maintains the braking force of the front, rear, left and right uniformly. The automatic braking system 1 is divided into a brake pedal 2 and a master cylinder. 3), the proportioning valve 4 and the brake caliper 5, the brake pedal 2 is responsible for lever lever to enable the driver to generate a large pressing force even with a small force.

특히, 상기 마스터실린더(3)는 유압회로에서 오일이 누출되면 자동제동시스템(1)이 작동불능상태가 되기 때문에 그 안정성을 높이기 위해 상기 브레이크페달(2)로 부터 힘을 받아 각 파이프(6)에 고압의 오일을 송출시키는 작용을 담당하게 된다.In particular, the master cylinder (3) receives the force from the brake pedal (2) to increase the stability of each pipe (6) because the automatic braking system (1) is inoperable when the oil leaks from the hydraulic circuit It is responsible for sending the high pressure oil.

또한, 상기 프로포션닝밸브(4)는 앞뒤바퀴에 각각 다르게 걸리는 제동력을 평형되게 유지시키는 기능을 담당하게 된다.In addition, the proportioning valve 4 is responsible for maintaining a balanced braking force applied to the front and rear wheels differently.

또한, 상기 브레이크캘리퍼(5)는 각각 차량의 프론트휠(7)측 디스크(8)를 중심으로 일측에 상기 브레이크캘리퍼(5)를 이루는 캘리퍼바디(9)의 내주면 피스톤(10)에 인너패드(11)가 구비되고 상기 인너패드(11)에 상응하여 상기 캘리퍼바디(9)의 타측에는 아웃터패드(12)가 구비됨으로써 차량의 운전자가 차량의 브레이크페달(2)을 밟을 시 상기 브레이크캘리퍼(5)의 양측 인너패드(11) 및 아웃터패드(12)가 상기 디스크(8)를 상호 밀착시키게됨에 따라 차량이 제동될 수 있게 하는 기능을 담당하게 된다.In addition, the brake caliper (5) is an inner pad (10) on the inner circumferential surface piston (10) of the caliper body (9) forming the brake caliper (5) on one side around the disk (8) of the front wheel (7) of the vehicle, respectively. 11 and the outer pad 12 is provided at the other side of the caliper body 9 corresponding to the inner pad 11 so that the brake caliper 5 when the driver of the vehicle steps on the brake pedal 2 of the vehicle. Both inner pads 11 and the outer pads 12) serve to brake the vehicle as the disk 8 comes into close contact with each other.

특히, 상기 캘리퍼바디(9)는 양측에 동일체로 형성되는 실린더부(13)에 차량의 브레이크캘리퍼(5)를 이루는 하우징(14)이 소정의 볼트(15)를 갖는 슬라이딩핀(16)으로 습동되게 연결됨으로써 차량의 제동시 상기 캘리퍼바디(9)와 상기 캘리퍼바디(9)의 내측 피스톤(10)이 차량용 프론트휠(7)의 디스크(8)측으로 상호 이동될 수 있게 된다.In particular, the caliper body 9 slides with a sliding pin 16 having a predetermined bolt 15 in a housing 14 constituting the brake caliper 5 of the vehicle in a cylinder 13 formed on the same side on both sides. In this case, the caliper body 9 and the inner piston 10 of the caliper body 9 can move to the disk 8 side of the front wheel 7 of the vehicle when the vehicle is braked.

또한, 상기 캘리퍼바디(9)의 피스톤(10)측 내주면 소정부위에 형성되는 결합요부(17)에는 리턴씰(18)이 구비됨으로써 차량의 운전자가 차량의 브레이크페달(2)을 밟았다 놓을 시 상기 캘리퍼바디(9)측 리턴씰(18)에 의해서 상기 피스톤(10)이 원래의 위치로 복귀될 수 있게 된다.In addition, a return seal 18 is provided in the coupling recess 17 formed at a predetermined portion of the inner surface of the piston 10 of the caliper body 9 so that the driver of the vehicle presses the brake pedal 2 of the vehicle. The return seal 18 on the caliper body 9 allows the piston 10 to return to its original position.

그러나, 일반적으로 차량의 운전자가 브레이크페달(2)을 밟았다 놓을 시 차량용 캘리퍼바디(9)측 리턴씰(18)이 복귀력이 취약하게 구비되어 있음으로 인해 상기 브레이크페달(2)의 계속적인 사용에 따라 상기 캘리퍼바디(9)의 피스톤(10)이 원래의 위치로 신속하게 복귀되지 못하게 되어 차량의 프론트휠(7)측 디스크(8)와 인너패드(11) 및 아웃터패드(12)의 마모가 가중되게 되는 문제점이 있었다.In general, however, when the driver of the vehicle steps on and releases the brake pedal 2, the return seal 18 of the vehicle caliper body 9 is provided with a weak return force, so that the continuous use of the brake pedal 2 is continued. As a result, the piston 10 of the caliper body 9 cannot be quickly returned to its original position, and thus the wear of the disc 8 and the inner pad 11 and the outer pad 12 on the front wheel 7 side of the vehicle is prevented. There was a problem that became weighted.

이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 차량의 운전자가 브레이크페달을 밟았다 놓을 시 차량의 브레이크캘리퍼를 이루는 캘리퍼바디의 피스톤이 원래의 위치로 신속히 복귀될 수 있게 하도록 한 차량용 브레이크캘리퍼의 복원력보강구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, the vehicle brake to enable the piston of the caliper body constituting the brake caliper of the vehicle to be quickly returned to its original position when the driver of the vehicle stepped on and release the brake pedal The purpose is to provide a resilience reinforcement structure of the caliper.
