본 발명은 디스크 브레이크에 관한 것으로, 더욱 상세하게는 캐리어에 설치되는 패드플레이트를 캐리어에 이동가능하게 지지하는 패드스프링을 갖춘 디스크 브레이크에 관한 것이다. The present invention relates to a disc brake, and more particularly, to a disc brake having a pad spring for movably supporting a pad plate installed on the carrier.                         

일반적으로 차량에 장착되는 디스크 브레이크는 주행 중의 자동차를 감속하거나 정지, 또는 정지 상태를 유지하기 위한 장치로서, 휠과 함께 회전하는 원판형의 디스크를 양쪽에서 패드로 강하게 압박하여 제동력을 얻는 것으로, 이의 구조는 다음과 같다.In general, a disc brake mounted on a vehicle is a device for decelerating, stopping or maintaining a vehicle while driving. A disc brake strongly presses a disk-shaped disk rotating together with a wheel with a pad to obtain braking force. The structure is as follows:

종래 디스크 브레이크는 제동유압에 의해 진퇴 운동하도록 피스톤이 내장된 캘리퍼 하우징과, 패드가 부착된 한 쌍의 패드플레이트가 설치되며 차체에 고정되는 캐리어와, 한 쌍의 패드플레이트 사이에 외주연 일부가 삽입되면서 휠과 함께 회전하는 디스크를 구비한다.Conventional disc brakes have a caliper housing with a built-in piston to move back and forth by braking hydraulic pressure, a pair of pad plates with pads installed thereon, a carrier fixed to the vehicle body, and a portion of an outer circumference inserted between the pair of pad plates. And a disk rotating with the wheel.

캘리퍼 하우징의 후방부에는 제동유압에 의해 진퇴되는 피스톤이 설치되어 일측의 패드플레이트를 밀게 되며, 이의 전방부에는 타측 패드플레이트를 감싸도록 굽어진 핑거부가 일체로 마련되어 타측 패드플레이트를 디스크측으로 밀게 된다.The rear part of the caliper housing is provided with a piston that is advanced and retracted by braking hydraulic pressure to push the pad plate on one side, and the front part of the caliper housing is integrally provided with a bent finger part to surround the other pad plate to push the other pad plate to the disc side.

캐리어는 차체의 너클에 볼트를 통해 장착되며, 내측에 두 패드플레이트가 슬라이딩 가능하게 설치된다. 그리고 패드플레이트와 캐리어사이에는 패드플레이트가 그 이동을 원활히 이룰 수 있도록 패드스프링이 마련된다.The carrier is mounted to the knuckle of the vehicle body through bolts, and two pad plates are slidably installed inside. In addition, a pad spring is provided between the pad plate and the carrier so that the pad plate can achieve its movement smoothly.

이러한 구성의 종래 디스크 브레이크는 운전자가 브레이크패달을 밟게 되면, 마스터실린더로부터 발생된 제동유압에 의해 피스톤과 핑거부가 패드플레이트를 밀게 되고, 양 패드플레이트는 캐리어 내을 진퇴하며 디스크를 가압하여 제동을 이루게 된다.In the conventional disc brake having such a configuration, when the driver presses the brake pedal, the piston and the finger portion push the pad plate by the braking hydraulic pressure generated from the master cylinder, and both pad plates move forward and backward in the carrier to press the disc to achieve braking. .

그러나, 종래 디스크 브레이크는 패드스프링이 패드플레이트의 이동을 가이드하게 되므로, 패드스프링과 패드플레이트 사이에는 소정의 유격이 존재하게 된 다.However, in the conventional disc brake, since the pad spring guides the movement of the pad plate, there is a predetermined gap between the pad spring and the pad plate.

이에 따라, 디스크 브레이크가 작동되어 패드플레이트가 캐리어 내를 진퇴하는 경우 패드플레이트와 패드스프링 사이의 유격에 의해 진동 및 소음이 발생하게 되며, 차량의 주행 시에도 패드플레이트와 패드스프링 사이의 유격에 의해 덜컥거리는 레틀노이즈가 발생하게 되는 문제점이 있다.Accordingly, when the disc brake is activated and the pad plate moves forward and backward in the carrier, vibration and noise are generated by the play between the pad plate and the pad spring, and the play between the pad plate and the pad spring also occurs when the vehicle is driven. There is a problem that rattling noise occurs.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 패드플레이트의 이동을 원활히 이루도록 함과 동시에 진동 및 소음을 저감할 수 있는 패드스프링을 갖춘 디스크 브레이크를 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a disk brake having a pad spring that can reduce vibration and noise while at the same time smoothly moving the pad plate.

다음에는 이와 같이 구성된 본 발명에 따른 디스크브레이크의 제동 작용 및 이에 따른 효과를 설명한다.Next, the braking action and the effects thereof of the disc brake according to the present invention configured as described above will be described.

자동차의 주행 중 운전자가 브레이크 패달(미도시)을 밟게 되면 마스터 실린더(미도시)에서 제동유압이 형성되고 마스터 실린더(미도시)에서 형성된 제동유압은 캘리퍼하우징(30)에 전달된다. When the driver steps on the brake pedal (not shown) while driving the vehicle, a braking hydraulic pressure is formed in the master cylinder (not shown), and the braking hydraulic pressure formed in the master cylinder (not shown) is transmitted to the caliper housing 30.

이러한 제동유압에 의해 캘리퍼하우징(30)의 일측에 마련된 실린더부(31)의 피스톤(32)은 일측 패드플레이트(40a)를 밀게 되고, 계속해서 제동유압에 의해 캘리퍼하우징(30)은 퇴진하고 그에 따라 캘리퍼하우징(30)의 타측에 마련되어 있는 핑거부(33)가 타측 패드플레이트(40b)를 밀게 된다.By the braking hydraulic pressure, the piston 32 of the cylinder portion 31 provided on one side of the caliper housing 30 pushes the pad plate 40a on one side, and the caliper housing 30 is subsequently retracted by the braking hydraulic pressure. Accordingly, the finger part 33 provided on the other side of the caliper housing 30 pushes the other pad plate 40b.

따라서, 두 패드플레이트(40a,40b)는 캐리어(20) 및 패드스프링(50)에 의해 가이드 되면서 디스크(10)를 압박하게 되는데, 이때 패드스프링(50)에 형성된 탄성부(52)가 일측이 캐리어(20)에 지지되면서 타측으로 패드플레이트(40a,40b)를 디스크(10)의 회전방향으로 지속적으로 밀게 됨에 따라, 패드플레이트(40a,40b)와 패드스프링(50) 또는 캐리어(20)와 패드스프링(50)간의 유격이 발생하지 않게 되어 패드플레이트(40a,40b)의 진퇴 시 발생되는 진동 및 소음을 억제할 수 있게 된다.Therefore, the two pad plates 40a and 40b are guided by the carrier 20 and the pad spring 50 to press the disc 10. At this time, the elastic portion 52 formed on the pad spring 50 has one side. As the pad plates 40a and 40b are continually pushed in the rotation direction of the disk 10 while being supported by the carrier 20, the pad plates 40a and 40b and the pad spring 50 or the carrier 20 and Since the gap between the pad springs 50 does not occur, it is possible to suppress the vibration and noise generated when the pad plates 40a and 40b move forward and backward.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 디스크 브레이크에 의하면, 패드스프링에 마련된 탄성부가 패드플레이트를 디스크의 회전방향으로 지속적으로 가압하게 된다. As described in detail above, according to the disk brake according to the present invention, the elastic portion provided in the pad spring is to continuously press the pad plate in the rotational direction of the disk.

이에 따라, 패드플레이트와 패드스프링 또는 캐리어와 패드스프링간의 유격이 발생하지 않게 되어 패드플레이트의 진퇴 시 발생되는 진동 및 소음을 억제할 수 있게 된다.Accordingly, the gap between the pad plate and the pad spring or the carrier and the pad spring does not occur, thereby suppressing vibration and noise generated when the pad plate is moved forward and backward.
