Description
본 발명은 차량의 운행 중에 속도를 감속하거나 정지시킬 수 있도록 하는 디스크 브레이크에 관한 것으로,The present invention relates to a disc brake that allows the vehicle to slow down or stop while driving.
특히 차량용 디스크 브레이크의 패드플레이트를 패드스프링으로 탄성 지지하여 패드에 의한 감속 및 제동작동 후에 패드가 신속하게 후퇴할 수 있도록 하는 디스크 브레이크에 관한 것이다. In particular, the present invention relates to a disc brake that elastically supports a pad plate of a disc brake for a vehicle with a pad spring so that the pad can retreat quickly after deceleration and braking operation by the pad.
일반적으로 차량에 장착되는 브레이크는 주행 중인 자동차를 감속하거나 정지, 또는 정지 상태를 유지하기 위해 마련되는 중요한 장치로서, 드럼 브레이크와 디스크 브레이크가 있으며, 이들 중에서 디스크 브레이크는 드럼 대신에 휠과 함께 회전하는 원판형의 디스크를 양쪽에서 패드로 압박하여 제동력을 얻을 수 있도록 한 것이다.In general, a brake mounted on a vehicle is an important device provided to decelerate, stop or maintain a driving vehicle, and includes a drum brake and a disc brake, among which a disk brake rotates together with a wheel instead of a drum. The disk-shaped disks were pressed by pads on both sides to obtain braking force.
이러한 종래 디스크 브레이크는 제동 유압에 의해 진퇴 운동하는 캘리퍼 하우징과, 차체에 고정되며 캘리퍼 하우징의 양단이 가이드로드를 통해 슬라이딩 가능하게 장착되는 캐리어와, 휠과 함께 회전하는 디스크의 양측에 설치하되 패드가 부착된 한 쌍의 패드플레이트를 로 구성한다.Such a conventional disc brake is installed on both sides of a caliper housing moving forward and backward by braking hydraulic pressure, a carrier fixed to a vehicle body, and both ends of the caliper housing slidably mounted through a guide rod, and a disk rotating together with a wheel, Consists of a pair of pad plates attached.
캘리퍼 하우징은 피스톤이 설치되는 실린더와, 핑거부를 갖추고 있어서 제동 작용 시 한 쌍의 패드플레이트를 디스크 측으로 밀게 된다. The caliper housing has a cylinder in which a piston is installed and a finger portion, so that a pair of pad plates are pushed to the disk side during braking.
또한 두 패드플레이트는 캐리어에 진퇴 가능하도록 장착되는데 피스톤과 마주하는 인너패드플레이트와, 핑거부와 마주하는 아웃터패드플레이트로 구별된다.In addition, the two pad plates are mounted to the carrier so as to be retractable, and are distinguished by an inner pad plate facing the piston and an outer pad plate facing the finger portion.
또한 두 패드플레이트의 상측에는 판상의 패드스프링이 설치되는데, 이러한 패드스프링은 소정의 탄성력으로 두 패드플레이트를 탄성지지하게 된다.In addition, the upper side of the two pad plate is provided with a plate-shaped pad spring, this pad spring is to elastically support the two pad plate with a predetermined elastic force.
따라서 운전자가 브레이크패달을 밟아 마스터실린더로부터 발생된 제동유압이 실린더에 전달되면, 피스톤과 함께 인너패드플레이트가 전진하며, 그 패드가 회전하는 디스크의 일측면에 순간적으로 압착된다.Therefore, when the driver presses the brake pedal and the braking hydraulic pressure generated from the master cylinder is transmitted to the cylinder, the inner pad plate moves forward with the piston, and the pad is momentarily compressed on one side of the rotating disk.
아울러 실린더에 잔존하는 유압에 의해 캘리퍼 하우징이 피스톤과 반대방향으로 이동하면서 핑거부가 아웃터패드플레이트를 밀어 이에 부착된 패드가 디스크의 타측면에 압착되어 제동력을 발휘한다.In addition, the caliper housing is moved in the opposite direction to the piston by the hydraulic pressure remaining in the cylinder, the finger portion pushes the outer pad plate, the pad attached thereto is pressed on the other side of the disk to exert a braking force.
이와 같은 제동시 패드스프링은 두 패드플레이트의 상측을 지속적으로 탄성지지함으로써 두 패드플레이트의 떨림을 방지하게 되고 그에 따른 래틀노이즈를 억제하게 된다.During braking, the pad springs continuously support the upper sides of the two pad plates to prevent shaking of the two pad plates, thereby suppressing rattle noise.
한편, 운전자가 브레이크패달을 놓으면 실린더에 작용하던 제동유압이 해제되며, 디스크와 패드의 마찰력(잔류 드래그, Residual Drag)에 의해 한 쌍의 패드플레이트와 함께 피스톤이 복원되면서 다시 디스크와 패드가 일정간격 이격된다.On the other hand, when the driver releases the brake pedal, the brake hydraulic pressure acting on the cylinder is released, and the piston and the pad are restored together with the pair of pad plates by the frictional force (residual drag) of the disk and the pad, and the disk and the pad are spaced again. Spaced apart.
그러나 종래의 상기와 같은 디스크 브레이크에서는 패드플레이트 상측에 마련된 패드스프링의 지지부가 평면으로 형성되어 패드스프링은 패드플레이트를 하측으로 누르는 탄성력만 가지는 것이므로 패드스프링은 디스크와 패드의 이격에는 아무런 작용을 하지 못하여 패드플레이트와 디스크간의 마찰력으로만 패드플레이트가 복원되었을 뿐만 아니라, 이로 인하여 패드플레이트의 복원이 원활하게 이루어지지 않는 문제점이 있었다.However, in the conventional disc brake as described above, the support portion of the pad spring provided on the upper side of the pad plate is formed in a flat surface, so the pad spring has only an elastic force that pushes the pad plate downward, so that the pad spring has no effect on the separation between the disk and the pad. Not only the pad plate was restored only by the frictional force between the pad plate and the disc, and thus, the pad plate was not smoothly restored.
또한 상기와 같이 패드플레이트와 디스크간의 마찰력으로만 패드플레이트를 복원시킴에 따라 패드플레이트의 복원이 원활하게 이루어지지 않는 문제점이 발생됨으로써 패드와 디스크간의 지속적인 접촉이 발생되고, 이에 따라 슬립현상이 발생되어 진동 및 소음이 발생하는 문제점이 있었다. In addition, as the pad plate is restored only by the frictional force between the pad plate and the disk as described above, there is a problem that the restoration of the pad plate is not performed smoothly, thereby causing continuous contact between the pad and the disk, thereby causing slippage. There was a problem that vibration and noise occur.
따라서 본 발명의 목적은 차량용 디스크 브레이크에서 패드플레이트를 패드스프링으로 탄성 지지하되 그 패드스프링은 중앙부 양측에 제1탄성부와 제2탄성부를 형성함으로써 패드에 의한 감속 및 제동작동 후에 패드플레이트와 디스크간의 마찰력과 패드스프링의 탄성력에 의해 패드를 신속하게 후퇴시킬 수 있을 뿐만 아니라, 이로 인하여 디스크와 패드의 마찰력 발생효율을 높일 수 있도록 한 디스크 브레이크를 제공함에 있다. Accordingly, an object of the present invention is to elastically support a pad plate with a pad spring in a vehicular disk brake, the pad spring having a first elastic part and a second elastic part on both sides of the center part, so that the pad plate and the disc may be separated after the deceleration and braking operation by the pad. Not only can the pad be quickly retracted by the friction force and the elastic force of the pad spring, but also provide a disc brake that can increase the frictional force generating efficiency of the disk and the pad.
이러한 본 발명의 목적은 차량의 휠과 함께 회전하는 디스크와, 상기 디스크를 압착하도록 내면에 패드가 부착되는 인너 패드플레이트 및 아웃터 패드플레이트와, 상기 인너 패드플레이트를 디스크에 압착시키는 피스톤과, 상기 피스톤이 설치된 캘리퍼 하우징과, 상기 캘리퍼하우징에 연결되어 아웃터 패드플레이트를 상대 운동시켜 디스크에 압착시키는 캐리어와, 상기 패드플레이트의 상측을 하방으로 탄성 지지함과 동시에 상기 패드플레이트를 상기 디스크 반대 방향으로 탄성 지지하도록 상기 패드플레이트의 상측에 설치되는 패드스프링과로 디스크브레이크를 구성함으로써 달성될 수 있다.Disclosure of the Invention An object of the present invention is a disk rotating together with a wheel of a vehicle, an inner pad plate and an outer pad plate having a pad attached to an inner surface thereof to compress the disk, a piston for compressing the inner pad plate to the disk, and the piston. A caliper housing installed therein, a carrier connected to the caliper housing to squeeze the outer pad plate relative to the disk and elastically supporting the upper side of the pad plate downward, and at the same time elastically supporting the pad plate in the opposite direction to the disk. It can be achieved by configuring the disc brake with a pad spring installed on the upper side of the pad plate.
이때 상기 패드스프링은 중앙에 평면으로 구성되는 중앙부와, 상기 중앙부의 양측에 일정한 경사각을 갖도록 형성하는 제1, 제2탄성부와, 상기 제1탄성부에 형성되고, 상기 캘리퍼하우징의 상부에 개구된 개구부에 인접 설치하되 상기 개구부의 전방측에 지지턱을 걸어서 설치되는 제1고정편과, 상기 제2탄성부에 형성되고, 상기 제1고정편의 대향측인 개구부의 후방측의 삽입턱에 삽입홈을 걸어서 설치되는 제2고정편과, 상기 중앙부의 정면과 후면에 형성되는 탄성부여부와를 구비한 것을 특징으로 한다.In this case, the pad spring is formed in a central portion having a flat surface in the center, first and second elastic portions formed to have a predetermined inclination angle on both sides of the central portion, and formed in the first elastic portion, and an opening in an upper portion of the caliper housing. A first fixing piece which is installed adjacent to the opened opening and is provided by hanging a support jaw on the front side of the opening, and is formed in the insertion jaw of the rear side of the opening which is formed on the second elastic part and is opposite to the first fixing piece. And a second fixing piece installed on a groove, and an elastic portion formed on the front and rear surfaces of the central portion.
한편 상기 제1탄성부와 제2탄성부는 중앙부에서 절곡선을 기점으로 상측을 향해 일정한 경사각을 이루도록 형성하여 패드플레이트를 외측으로 미는 힘이 작용되도록 구성한 것을 특징으로 한다. On the other hand, the first elastic portion and the second elastic portion is formed to form a predetermined inclination angle toward the upper side starting from the bending line in the center portion is characterized in that configured to act to push the pad plate to the outside.

Meanwhile, the elastic part 840 is provided at the front and rear sides of the central part 810, and the front and rear sides of the central part 810 are substantially symmetric with each other and are formed to be inclined upwardly from the central part 810. Both ends of the 840 support the caliper housing 100 to impart elastic force to the first elastic portion 812 and the second elastic portion 814.
다음에는 이와 같이 구성된 본 발명에 따른 디스크 브레이크의 작용 및 이에 따른 효과를 설명한다.Next, the operation of the disc brake according to the present invention configured as described above and the effects thereof will be described.
먼저, 자동차가 주행하고 있는 상태에서 운전자가 브레이크패달(미도시)을 밟으면, 마스터실린더와 같은 유압원에서 제동유압이 형성되고 이것은 실린더(110)로 전달되어 피스톤(200)을 전진시킨다.First, when the driver presses a brake pedal (not shown) while the vehicle is running, a braking hydraulic pressure is formed in a hydraulic source such as a master cylinder, which is transmitted to the cylinder 110 to advance the piston 200.
이에 따라 캐리어(300)에 설치된 인너 패드플레이트(500)가 전진하면서 회전하는 디스크(700)의 측면에 패드(510)를 마찰시켜 제동력을 발생시키고, 실린더(110)에 잔존하는 유압에 의해 캘리퍼하우징(100)은 피스톤(200)과 반대방향으로 이동하며, 이것에 의해 핑거부(120)가 아웃터 패드플레이트(600)를 끌어 당겨 이의 패드(610)가 디스크(700) 측면에 압착 제동력이 발생된다.Accordingly, the inner pad plate 500 installed on the carrier 300 moves forward to friction the pad 510 on the side of the rotating disk 700 to generate braking force, and the caliper housing is driven by the hydraulic pressure remaining in the cylinder 110. 100 moves in the opposite direction to the piston 200, whereby the finger portion 120 pulls the outer pad plate 600 so that the pad 610 has a crimping braking force on the disk 700 side. .
이처럼 양 패드플레이트(500)(600)의 이동시 패드스프링(800)의 제1, 제2탄성부(812)(814)가 탄성부여부(840)로부터 부여받은 탄성력으로 패드플레이트(500)(600)의 상측을 지속적으로 탄성 지지하게 되어 양 패드플레이트(500)(600)의 떨림 현상을 억제하게 된다.As such, when the two pad plates 500 and 600 are moved, the first and second elastic parts 812 and 814 of the pad spring 800 are pad pads 500 and 600 by the elastic force applied from the elastic applying part 840. The elasticity of the upper side of the pad is continuously supported to suppress the shaking of the pad plates 500 and 600.
특히 본 발명은 중앙부(810)에서 절곡선(811)(813)을 기점으로 일정한 경사각(θ)을 유지하도록 절곡형성된 제1탄성부(812)와 제2탄성부(814)가 자체의 탄성력으로 양 패드플레이트(500)(600)를 아래로 누르는 힘과 밖으로 벌리는 힘으로 작용하게 된다.Particularly, in the present invention, the first elastic portion 812 and the second elastic portion 814, which are bent to maintain a constant inclination angle θ from the bend lines 811 and 813 at the central portion 810, have their own elastic force. Both pad plates 500 and 600 act as a force to push down and a force to spread out.
따라서 운전자가 브레이크패달을 놓아 제동유압이 해제되면, 휠과 함께 회전하는 디스크(700)와 각 패드(510)(610)사이의 마찰력(잔류 드래그, Residual Drag)에 의해 패드플레이트(500)(600)가 디스크(700)와 이격될 뿐만 아니라, 제1탄성부(812)와 제2탄성부(814)의 탄성력이 패드플레이트(500)(600)와 디스크(700)의 이격을 돕게 되므로 패드플레이트(500)(600)와 디스크(700)의 이격이 신속하게 이루어지게 된다.Therefore, when the driver releases the brake pedal and the brake hydraulic pressure is released, the pad plates 500 and 600 are caused by frictional force (residual drag) between the disk 700 and the pads 510 and 610 rotating together with the wheels. In addition to being spaced apart from the disk 700, since the elastic force of the first elastic portion 812 and the second elastic portion 814 helps the separation between the pad plate 500, 600 and the disk 700, the pad plate The separation between the 500 and 600 and the disk 700 is made quickly.
그러므로 패드(510)(610)와 디스크(700)간의 슬립현상이 억제되어 그에 따른 소음 및 진동을 방지할 수 있게 되고, 디스크(700)와 패드(510)(610)의 마찰력 발생효율을 높일 수 있게 된다. Therefore, the slip phenomenon between the pads 510 and 610 and the disk 700 can be suppressed to prevent noise and vibration, and the frictional force generating efficiency of the disk 700 and the pads 510 and 610 can be improved. Will be.
상기에서와 바와 같이 본 발명은 차량용 디스크 브레이크에서 패드플레이트를 패드스프링으로 탄성 지지하되 그 패드스프링은 중앙부 양측에 제1탄성부와 제2탄성부를 형성함으로써 패드에 의한 감속 및 제동작동 후에 패드플레이트와 디스크간의 마찰력과 패드스프링의 탄성력에 의해 패드를 신속하게 후퇴시킬 수 있을 뿐만 아니라, 이로 인하여 디스크와 패드의 마찰력 발생효율을 높일 수 있는 효과가 제공되는 것이다.As described above, the present invention elastically supports the pad plate with the pad spring in the disc brake of the vehicle, which pad spring is formed with the first elastic part and the second elastic part on both sides of the center part, and thus the pad plate and the pad plate after the deceleration and braking operation by the pad. Not only can the pad be quickly retracted by the friction force between the disks and the elastic force of the pad spring, thereby providing an effect of increasing the friction generating efficiency of the disk and the pad.
