Abstract

The present invention relates to a pressure plate for adjusting a surface pressure of an automobile disc brake. An area of a left unit (12) on a leading side is wider than the same of a right unit (14) on a riding side, so a pressing force on an inner brake pad (28) is weakened by dispersion of a force in the left unit (12) during braking. Therefore, a large load applied to the leading side of the inner brake pad (28) by a disk (30) is offset, so the inner brake pad (28) presses the disk (30) under a uniform surface pressure as a whole to achieve braking.

Description

자동차 디스크 브레이크의 면압조정용 가압 플레이트{Pressurization plate for face pressure adjustment of automobile disc brakes}Pressurization plate for face pressure adjustment of automobile disc brakes

본 발명은 자동차 디스크 브레이크의 면압조정용 가압 플레이트에 관한 것으로서, 상세하게는 회전하는 디스크에 의해 브레이크패드의 리딩측에 주어지는 하중을 적절히 상쇄시켜서 제동시 브레이크패드에 전체적으로 균일한 면압이 주어질 수 있도록 한 것이다.The present invention relates to a pressure plate for adjusting the surface pressure of a disc brake of an automobile, and more particularly, to appropriately offset the load applied to the leading side of the brake pad by a rotating disc so that a uniform surface pressure can be applied to the brake pad as a whole during braking. .

일반적으로 자동차용 디스크 브레이크는 휠과 함께 회전하는 디스크를 사이에 두고 캐리어측의 피스톤에 결합되는 내측브레이크패드와 하우징에 결합되는 외측브레이크패드가 서로 마주하도록 하여 주행중 운전자가 브레이크패달을 밟게 되면 피스톤의 작동으로 내측브레이크패드가 디스크를 가압해주도록 함과 아울러 그 가압력에 의해 하우징이 캐리어로부터 슬라이딩하면서 외측브레이크패드도 디스크를 가압하여 제동이 이루어지도록 구성된다.In general, disc brakes for automobiles have the inner brake pad coupled to the piston on the carrier side and the outer brake pad coupled to the housing face each other with a disk rotating together with the wheel interposed therebetween. The inner brake pad presses the disk by operation, and the housing slides from the carrier by the pressing force, and the outer brake pad also presses the disk to achieve braking.

다만 이러한 제동시 내측브레이크패드를 가압하는 피스톤은 가압면의 면적이 작아 면적이 넓은 브레이크패드를 전체적으로 가압해줄 수 없게 되므로 소음 및 진동이 심하게 발생하게 되고 또 제동이 안정감 있게 이루어질 수 없게 된다.However, when braking, the piston pressing the inner brake pad has a small pressing surface, so it cannot press the large brake pad as a whole, so noise and vibration are severely generated, and braking cannot be performed stably.

따라서 피스톤과 내측 브레이크패드 사이에 면적이 넓은 가압플레이트를 결합하여 피스톤의 가압력을 내측브레이크패드에 전체적으로 전달해줄 수 있도록 한 자동차 디스크 브레이크의 면압조정용 가압 플레이트에 대하여 이미 미국공개특허 US 2014/0284152 '디스크 브레이크, 특히 상용차의 디스크 브레이크의 압력플레이트 및 디스크 브레이크의 브레이크패드' 및 미국특허 US 9,291,226 '디스크 브레이크 및 디스크 브레이크용 압력플레이트와 브레이크패드' 등이 제공된바 있다.Therefore, with respect to the pressure plate for adjusting the surface pressure of a car disc brake that combines the pressure plate with a large area between the piston and the inner brake pad to transmit the pressure of the piston to the inner brake pad as a whole, US Patent Publication US 2014/0284152 'Disc Brakes, in particular, a pressure plate for a disc brake of a commercial vehicle and a brake pad for a disc brake' and US Pat. No. 9,291,226 'Pressure plate and brake pad for a disc brake and disc brake' have been provided.

그러나 상기한 자동차 디스크 브레이크의 면압조정용 가압 플레이트는 디스크 브레이크 고유의 특수성을 감안하지 않고 단순히 가압플레이트를 브레이크패드의 백플레이트와 유사한 외형을 갖도록 좌우대칭형으로 넓게 형성되므로 피스톤의 가압력을 브레이크패드에 전체적으로 고르게 전달해줄 수는 있다 하겠으나, 직선운동하는 브레이크패드가 회전운동하는 디스크를 가압할 시 디스크의 회전토크로 인하여 내측브레이크패드가 디스크의 회전방향으로 밀리면서 리딩측에 라이딩측에 비해 큰 하중이 가해지게 되면 편마모가 발생하게 되므로 사용수명단축에 의한 금전적손실을 가져오게 됨은 물론 브레이크패드의 면압불균형으로 인하여 제동력저하로 이어지게 되는 등 많은 문제점들이 발생하게 된다.However, the pressure plate for adjusting the surface pressure of the automobile disc brake is not considered the specificity of the disc brake and is simply formed in a wide symmetrical shape to have an external shape similar to the back plate of the brake pad, so that the pressing force of the piston is applied evenly to the brake pad as a whole. It can be delivered, but when a linear brake pad presses a rotating disk, the inner brake pad is pushed in the rotational direction of the disk due to the rotational torque of the disk, and a greater load is applied to the leading side compared to the riding side. When this happens, uneven wear occurs, resulting in financial loss due to shortening of the service life, and many problems such as lowering of braking force due to uneven surface pressure of the brake pad.

본 발명의 목적은 제동시 디스크에 의해 브레이크패드의 리딩측에 가해지는 큰 하중을 상쇄시켜서 브레이크패드가 전체적으로 균일한 면압하에서 디스크를 가압하여 제동이 이루어지도록 할 수가 있는 자동차 디스크 브레이크의 면압조정용 가압 플레이트를 제공하는데 있다.An object of the present invention is to offset the large load applied to the leading side of the brake pad by the disc during braking, so that the brake pad presses the disc under a uniform surface pressure as a whole so that braking can be achieved. is to provide

상기한 목적달성을 위한 본 발명 자동차 디스크 브레이크의 면압조정용 가압 플레이트는 라이딩측인 우측부에 비해 리딩측인 좌측부의 면적을 넓게 형성하여 제동시 좌측부는 힘의 분산으로 내측브레이크패드에 대한 가압력을 약화시켜서 디스크에 의해 내측브레이크패드의 리딩측에 가해지는 큰 하중을 상쇄시켜주도록 구성함을 특징으로 한다.In order to achieve the above object, the pressure plate for adjusting the surface pressure of the disc brake of the present invention of the present invention makes the area of the left side of the leading side wider than the right side of the riding side, so that the left side during braking weakens the pressing force on the inner brake pad by dispersing the force. It is characterized in that it is configured to offset the large load applied to the leading side of the inner brake pad by the disc.

본 발명은 제동시 디스크에 의해 내측브레이크패드의 리딩측에 가해지는 큰 하중을 상쇄시켜서 내측브레이크패드가 전체적으로 균일한 면압하에서 디스크를 가압하여 제동이 이루어지도록 할 수가 있게 되므로 브레이크패드의 사용수명을 보장해줄 수 있고 또 면압불균형에 의한 제동력저하를 방지해줄 수 있게 되는 등의 효과를 기대할 수 있게 된다.The present invention ensures the service life of the brake pad because it is possible to offset the large load applied to the leading side of the inner brake pad by the disk during braking, so that the inner brake pad presses the disk under a uniform surface pressure as a whole to achieve braking. In addition, effects such as being able to prevent a decrease in braking force due to surface pressure imbalance can be expected.

The pressure plate 10 for adjusting the surface pressure of the disc brake of the present invention is the leading side, and the left part 12 has a wide area and the riding side The right side portion 14 has a narrow area, and is formed by forming coupling grooves 20 and 22 for coupling the distal ends of the pistons 16 and 18 on the surface facing the pistons 16 and 18. do.

도 3은 본 발명의 설치시를 보여주는 분해사시도이고, 도 4는 본 발명의 사용상태를 보여주는 사시도로서, 본 발명은 자동차 디스크 브레이크(24)의 하우징(26) 측에 설치되는 피스톤(16)(18)과 내측브레이크패드(28) 사이에 결합하여 피스톤(16)(18)의 작동시 피스톤(16)(18)에 의해 가해지는 가압력을 내측브레이크패드(28)에 전달하여 제동이 이루어지도록 하게 된다.Figure 3 is an exploded perspective view showing the installation of the present invention, Figure 4 is a perspective view showing the use state of the present invention, the present invention is a piston 16 installed on the housing 26 side of the disc brake 24 of the automobile ( 18) and the inner brake pad 28 to transmit the pressing force applied by the pistons 16 and 18 to the inner brake pad 28 when the pistons 16 and 18 are operated to achieve braking. do.

즉, 주행중 운전자가 브레이크패달을 밟게 되면 피스톤(16)(18)은 본 발명 면압조정용 가압 플레이트(10)가 피스톤(16)(18)의 가압력을 내측브레이크패드(28)에 전달하여 내측브레이크패드(28)가 디스크(30)를 가압하도록 함과 아울러 그 가압력에 의해 하우징(28)과 브릿지(32)가 캐리어(34)로부터 슬라이딩하면서 외측브레이크패드(36)도 디스크(30)를 가압하여 제동이 이루어지도록 하게 된다.That is, when the driver steps on the brake pedal while driving, the pistons 16 and 18 transmit the pressing force of the pistons 16 and 18 to the inner brake pad 28 by the pressure plate 10 for adjusting the surface pressure of the present invention to the inner brake pad. As the housing 28 and the bridge 32 slide from the carrier 34 by the pressing force, the outer brake pad 36 also presses the disk 30 to brake will make this happen.

그리고 이러한 제동시 직선운동하는 내측브레이크패드(28)가 회전운동하는 디스크(30)를 가압하게 되면 내측브레이크패드(28)는 디스크(30)의 회전토크로 인하여 디스크(30)의 회전방향으로 밀리면서 리딩측에는 라이딩측에 비해 큰 하중이 가해지게 되나, 피스톤(16)(18)의 가압력을 내측브레이크패드(28)에 전달하는 본 발명 면압조정용 가압 플레이트(10)는 리딩측인 좌측부(12)가 라이딩측인 우측부(14)에 비해 면적이 넓어 좌측부(12)는 힘의 분산에 의한 가압력의 약화로 디스크에 의해 내측브레이크패드(28)의 리딩측에 가해지는 큰 하중을 상쇄시켜주게 되므로 내측브레이크패드(28)는 전체적으로 균일한 면압하에서 디스크(30)를 가압하여 제동이 이루어지도록 하게 된다.And when the linearly moving inner brake pad 28 presses the rotating disk 30 during braking, the inner brake pad 28 is pushed in the rotational direction of the disk 30 due to the rotational torque of the disk 30 . While a larger load is applied to the leading side compared to the riding side, the present invention that transmits the pressing force of the pistons 16 and 18 to the inner brake pad 28. The pressure plate 10 for adjusting the surface pressure of the present invention is the leading side, the left part 12 Since the area is wider than that of the right part 14, which is the temporary riding side, the left part 12 offsets the large load applied to the leading side of the inner brake pad 28 by the disc due to the weakening of the pressing force due to the dispersion of the force. The inner brake pad 28 presses the disk 30 under a uniform surface pressure as a whole to achieve braking.

따라서 본 발명은 제동시 디스크에 의해 내측브레이크패드(28)의 리딩측에 가해지는 큰 하중을 상쇄시켜서 내측브레이크패드(28)가 전체적으로 균일한 면압하에서 디스크(30)를 가압하여 제동이 이루어지도록 할 수가 있게 되므로 브레이크패드의 사용수명을 보장해줄 수 있고 또 면압불균형에 의한 제동력저하를 방지해줄 수가 있게 된다.Therefore, the present invention offsets the large load applied to the leading side of the inner brake pad 28 by the disk during braking so that the inner brake pad 28 presses the disk 30 under a uniform surface pressure to achieve braking. Therefore, it is possible to guarantee the service life of the brake pad and to prevent the decrease in braking force due to uneven surface pressure.
