Description

완충부재가 구비된 디스크 브레이크{Disk brake with damping material}Disk brake with damping material

본 발명은 디스크 브레이크의 패드 플레이트에 관한 것으로, 더욱 상세하게는 패드 플레이트에 비금속성 완충부재가 구비되어 있는 디스크 브레이크에 관한 것이다.The present invention relates to a pad plate of a disc brake, and more particularly, to a disc brake having a non-metallic shock absorbing member provided on the pad plate.

종래의 디스크 브레이크는 도 1에 도시되어 있는 바와 같이, 차량의 바퀴와함께 회전하는 디스크(10)의 양측에 마찰패드(41, 41')가 부착된 한 쌍의 패드 플레이트(40, 40')가 구비된다. 이때 이들 패드 플레이트(40, 40')는 차량의 너클부(미도시)에 고정되는 캐리어(30)에 의하여 지지되는데, 각 패드 플레이트(40, 40')의 양단에 형성된 돌출부(42, 42')가 이와 대응하도록 캐리어의 양측에 형성된 안착홈(31)에 끼워짐으로써 패드 플레이트(40, 40')가 디스크(10) 쪽으로 진퇴 가능하게 지지된다.As shown in FIG. 1, a conventional disc brake includes a pair of pad plates 40 and 40 'having friction pads 41 and 41' attached to both sides of a disc 10 that rotates together with a wheel of a vehicle. Is provided. At this time, these pad plates 40, 40 'are supported by a carrier 30 fixed to a knuckle portion (not shown) of the vehicle, and protrusions 42, 42' formed at both ends of each pad plate 40, 40 '. The pad plate 40, 40 'is supported by the disc 10 in a retractable manner by being fitted into the mounting groove 31 formed on both sides of the carrier so as to correspond thereto.

또한 캐리어(30)의 외측에는 디스크(10) 양측에 배치된 두 개의 패드 플레이트(40, 40')를 디스크(10) 쪽으로 가압하는 캘리퍼 하우징(20)이 마련된다.In addition, the outer side of the carrier 30 is provided with a caliper housing 20 for pressing the two pad plates 40, 40 'disposed on both sides of the disk 10 toward the disk 10.

이때 캘리퍼 하우징(20)의 일측에는 내측 패드 플레이트(40, 40')를 디스크(10) 쪽으로 가압하도록 피스톤(21a)이 설치된 실린더부(21)가 마련되고, 실린더부(21)의 타측에는 맞은편의 외측 패드 플레이트(40, 40')의 이면을 지지하는 핑거부(22)가 마련된다.At this time, one side of the caliper housing 20 is provided with a cylinder portion 21 provided with a piston 21a to press the inner pad plate 40, 40 'toward the disk 10, and the other side of the cylinder portion 21 is fitted. A finger portion 22 is provided that supports the back surface of the bias outer pad plates 40, 40 '.

그리고 캘리퍼 하우징(20)의 양측에는 캘리퍼 하우징(20)이 캐리어(30)에 미끄럼 가능하게 결합될 수 있도록 안내봉(23)이 마련되고, 캐리어(30)의 양측에는 안내봉(23)이 끼워져 안내봉(23)을 유도하는 안내공(33)이 형성된다.And guide rods 23 are provided on both sides of the caliper housing 20 so that the caliper housing 20 can be slidably coupled to the carrier 30, and guide rods 23 are fitted to both sides of the carrier 30. Guide holes 33 for guiding the guide rods 23 are formed.

이러한 차량용 디스크 브레이크에 있어서, 유압이 캘리퍼 하우징(20)으로 전해지면 실린더부(21)의 피스톤(21a)과 핑거부(22)가 그 사이에 구비되어 있는 디스크(10) 측으로 이동하여 패드 플레이트(40, 40')와 마찰패드(41, 41')를 압박, 제동이 일어나게 된다.In the vehicular disk brake, when the hydraulic pressure is transmitted to the caliper housing 20, the piston plate 21a and the finger portion 22 of the cylinder portion 21 are moved to the side of the disk 10 provided with the pad plate ( 40, 40 ') and the friction pads 41, 41' are pressed and brake occurs.

이때 회전하는 디스크(10)에 접하게 됨으로 패드 플레이트(40, 40')에는 진동이 발생한다. 패드 플레이트(40, 40')가 진동하게 되면 패드 플레이트(40, 40')와 패드 플레이트(40, 40')를 지지하고 있는 캐리어(30)가 모두 금속 재질로 구비되어 있고, 상호간에 어느 정도의 공차를 가지고 설치되어 있기 때문에 작동 중 서로 부딪쳐 소음(rattle noise)이 발생하게 된다.At this time, the vibration occurs in the pad plates 40 and 40 'because they come into contact with the rotating disk 10. When the pad plates 40 and 40 'vibrate, both the pad plates 40 and 40' and the carrier 30 supporting the pad plates 40 and 40 'are made of a metal material. Because they are installed with tolerances of each other, they collide with each other during operation, resulting in rattle noise.

따라서 패드 플레이트(40, 40')와 캐리어(30) 사이에는 이러한 소음을 방지하기 위하여 완충부재로써 패드 스프링(50)이 구비된다.Therefore, a pad spring 50 is provided as a cushioning member between the pad plates 40 and 40 'and the carrier 30 to prevent such noise.

통상적으로 패드 스프링(50)은 금속재질의 판 스프링으로, 캐리어(30)의 안착홈(31)에 안착되어 패드 플레이트(40, 40')를 완충지지하여 줌으로써 패드 플레이트(40, 40')의 진동을 감쇄시켜 소음을 감소시킨다.In general, the pad spring 50 is a plate spring made of metal, and is seated in the seating groove 31 of the carrier 30 to cushion and support the pad plates 40 and 40 '. Attenuates vibration to reduce noise.

그러나 패드 플레이트(40, 40')와 캐리어(30)의 안착홈(31)은 모두 금속 재질로 이루어져 있으며, 패드 스프링(50) 또한 금속 재질로 이루어져 있으므로 패드 스프링(50)의 완충작용에 의하여 진동이 줄어들어 소음은 감소하기는 하지만, 진동에 의하여 패드 스프링(50)이 패드 플레이트(40, 40') 또는 캐리어(30)에 부딪쳐 소음을 발생시키는 소음원으로 작용하게 된다는 문제점이 있다.However, the pad plates 40 and 40 'and the seating groove 31 of the carrier 30 are all made of a metal material, and the pad spring 50 is also made of a metal material, and thus vibrates by the cushioning action of the pad spring 50. Although the noise is reduced due to this reduction, there is a problem that the pad spring 50 acts as a noise source to generate noise by hitting the pad plates 40 and 40 'or the carrier 30 by vibration.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 패드 플레이트와 캐리어 사이에 비금속성 완충부재를 구비함으로써,The present invention is to solve this problem, by providing a non-metallic buffer member between the pad plate and the carrier,

패드 플레이트와 캐리어가 진동으로 서로 부딪치며 소음을 발생시키는 것을 방지하며, 동시에 완충부재가 소음원으로 작용하는 것을 방지하고자 한다.To prevent the pad plate and the carrier from hitting each other with vibration and generating noise, and at the same time to prevent the buffer member from acting as a noise source.

이하에서는 본 발명에 따른 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

본 발명이 적용되는 디스크 브레이크는 도 2에 도시되어 있는 바와 같이, 차량의 바퀴와 함께 회전하는 디스크(10)의 양측에 마찰패드(41, 41')가 부착된 한 쌍의 패드 플레이트(40, 40')가 구비된다.As shown in FIG. 2, a disc brake to which the present invention is applied includes a pair of pad plates 40 having friction pads 41 and 41 'attached to both sides of the disc 10 rotating together with the wheels of the vehicle. 40 ') is provided.

이때 이들 패드 플레이트(40, 40')는 차량의 너클부(미도시)에 고정되는 캐리어(30)에 의하여 지지되는데, 각 패드 플레이트(40, 40')의 양단에 형성된 돌출부(42, 42')가 이와 대응하도록 캐리어(30)의 양측에 형성된 안착홈(31)에 끼워짐으로써 패드 플레이트(40, 40')가 디스크 쪽으로 진퇴 가능하게 지지된다.At this time, these pad plates 40, 40 'are supported by a carrier 30 fixed to a knuckle portion (not shown) of the vehicle, and protrusions 42, 42' formed at both ends of each pad plate 40, 40 '. The pad plate 40, 40 'is supported by the disc so as to be able to move forward and backward by being fitted into the mounting groove 31 formed on both sides of the carrier 30 so as to correspond thereto.

또한 캐리어(30)의 외측에는 디스크(10) 양측에 배치된 두 패드 플레이트(40, 40')를 디스크(10) 쪽으로 가압하는 캘리퍼 하우징(20)이 마련된다.In addition, the outer side of the carrier 30 is provided with a caliper housing 20 for pressing the two pad plates 40, 40 'disposed on both sides of the disk 10 toward the disk 10.

이때 캘리퍼 하우징(20)의 일측에는 내측 패드 플레이트(40, 40')를 디스크(10) 쪽으로 가압하도록 피스톤(21a)이 설치된 실린더부(21)가 마련되고, 실린더부(21)의 타측에는 맞은편의 외측 패드 플레이트(40, 40')의 이면을 지지하는 핑거부(22)가 마련된다.At this time, one side of the caliper housing 20 is provided with a cylinder portion 21 provided with a piston 21a to press the inner pad plate 40, 40 'toward the disk 10, and the other side of the cylinder portion 21 is fitted. A finger portion 22 is provided that supports the back surface of the bias outer pad plates 40, 40 '.

그리고 캘리퍼 하우징(20)의 양측에는 캘리퍼 하우징(20)이 캐리어(30)에 미끄럼 가능하게 결합될 수 있도록 안내봉(23)이 마련되고, 캐리어(30)의 양측에는 안내봉(23)이 끼워져 안내봉(23)을 유도하는 안내공(33)이 형성된다.And guide rods 23 are provided on both sides of the caliper housing 20 so that the caliper housing 20 can be slidably coupled to the carrier 30, and guide rods 23 are fitted to both sides of the carrier 30. Guide holes 33 for guiding the guide rods 23 are formed.

그리고 본 발명에 따라 패드 플레이트(40, 40')의 돌출부(42, 42')과 캐리어(30)의 안착홈(31) 사이에는 비금속성 완충부재(50')가 구비된다.According to the present invention, a non-metallic shock absorbing member 50 'is provided between the protrusions 42 and 42' of the pad plates 40 and 40 'and the seating groove 31 of the carrier 30.

다음에는 이와 같이 구성된 본 발명에 따른 차량용 브레이크 부스터의 동작을 상세히 설명한다.Next, the operation of the vehicle brake booster according to the present invention configured as described above will be described in detail.

운전자가 브레이크 페달을 밟아 유압이 캘리퍼 하우징(20)으로 전해지면 피스톤(21a)과 핑거부(22)가 내측으로 이동하면서 패드 플레이트(40, 40')와 마찰패드(41, 41')를 가압하고, 그에 따라 두 개의 마찰패드(41, 41') 중간에 구비되어 있는 디스크(10)를 가압, 제동이 발생하게 된다.When the driver presses the brake pedal and hydraulic pressure is transmitted to the caliper housing 20, the piston 21a and the finger portion 22 move inward to press the pad plates 40 and 40 'and the friction pads 41 and 41'. As a result, the disk 10 provided in the middle of the two friction pads 41 and 41 'is pressed and brake is generated.

이때, 디스크(10)의 회전운동을 마찰패드(41, 41')에 의하여 강제로 정지시킴으로 인하여 마찰패드(41, 41')와 패드 플레이트(40, 40')에는 진동이 발생하게 된다. 패드 플레이트(40, 40')에 진동이 발생하게 되면 패드 플레이트(40, 40')의 돌출부(42, 42')가 캐리어(30)의 안착홈(31)에 안착되어 있으므로 캐리어(30)의 안착홈(31)과 부딪쳐 소음을 발생시키게 된다.At this time, vibration is generated in the friction pads 41 and 41 'and the pad plates 40 and 40' by forcibly stopping the rotational movement of the disk 10 by the friction pads 41 and 41 '. When vibration occurs in the pad plates 40 and 40 ', the protrusions 42 and 42' of the pad plates 40 and 40 'are seated in the seating grooves 31 of the carrier 30. The noise hits the mounting groove 31.

그러나 본 발명에 따라 패드 플레이트(40, 40')의 돌출부(42, 42')에는 비금속성 완충부재(50')가 씌워져 있으므로 작동 중 발생되는 진동이 비금속성 완충부재(50')에 의하여 감쇄되고, 각 부품, 특히 패드 플레이트(40, 40')와 캐리어(30)가 부딪치더라도 소음이 발생되지 않는다. 또한 합성수지나 합성고무 등의 비금속성 완충부재(50')로 구비되어 있으므로 소음을 발생시키는 소음원으로 작용하지 않는다.However, according to the present invention, since the protrusions 42 and 42 'of the pad plates 40 and 40' are covered with a nonmetallic buffer member 50 ', vibration generated during operation is attenuated by the nonmetallic buffer member 50'. No noise is generated even when the components, particularly the pad plates 40 and 40 'and the carrier 30 collide with each other. In addition, since it is provided with a non-metallic shock absorbing member 50 'such as synthetic resin or synthetic rubber, it does not act as a noise source for generating noise.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 디스크 브레이크에는 패드 플레이트의 돌출부에 합성수지, 합성고무 등의 비금속성 완충부재가 사용됨으로써, 제동 시 발생되는 진동으로 인하여 패드 플레이트와 캐리어가 부딪쳐 소음을 발생시키는 것을 방지하며, 또한 완충부재가 패드 플레이트 또는 캐리어와 부딪쳐 완충부재가 소음을 발생시키는 소음원으로써 작용하는 것을 방지한다.As described in detail above, in the disc brake according to the present invention, non-metallic shock absorbing members, such as synthetic resin and synthetic rubber, are used in the protrusions of the pad plate, so that the pad plate and the carrier collide with each other due to vibration generated during braking to generate noise. It also prevents the shock absorbing member from colliding with the pad plate or the carrier and acting as a noise source generating noise.
