Description
본 발명은 자동차의 디스크브레이크 구조에 관한 것으로, 특히 제동시 발생하는 피스톤의 회전모멘트를 최대한 억제시킴으로써 브레이크패드의 편마모를 최대한 예방함과 더불어 저더(juder)현상을 감소시킬 수 있도록 하는 자동차의 디스크브레이크 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake structure of an automobile. In particular, the disc brake of an automobile is capable of preventing judging and at the same time preventing uneven wear of the brake pad by maximally suppressing the rotation moment of the piston generated during braking. It's about structure.
일반적으로, 차량의 제동장치로서 사용되는 디스크브레이크의 구조는 도 1과 도 2에 도시된 바와 같이, 주철재질의 안장모양으로 형성되어 너클스핀들에 부착되는 캘리퍼하우징(11)과, 이 캘리퍼하우징(11)에 의해 형성된 휠실린더(12)내에 장착되면서 유압의 힘을 이용해 직선으로 이동하는 피스톤(13)과, 상기 캘리퍼하우징(11)의 전면에 가이드로드(14)를 매개로 결합되는 캘리퍼캐리어(15)와, 양측면에 형성된 슬라이드돌기(16a)가 상기 캘리퍼캐리어(15)에 형성된 슬라이드홈(15a)으로 끼워짐으로써 상기 캘리퍼캐리어(15)와 결합되는 백플레이트(16)와, 이 백플레이트(16)의 전면에 결합되어 상기 피스톤(13)이 유압의 힘을 이용해 작동될 때 디스크(23)의 양측면을 가압하면서 마찰력에 의한 제동력을 발생시키도록 하는 브레이크패드(17)를 포함하여 구성된다.In general, the structure of the disc brake to be used as a braking device of a vehicle is a caliper housing 11 formed in a saddle shape made of cast iron and attached to knuckle spindles, as shown in FIGS. 1 and 2, and the caliper housing ( A piston 13 which is mounted in the wheel cylinder 12 formed by 11 and moves in a straight line using hydraulic force, and a caliper carrier coupled to the front surface of the caliper housing 11 by a guide rod 14. 15, a back plate 16 coupled to the caliper carrier 15 by fitting the slide projections 16a formed on both sides into the slide groove 15a formed on the caliper carrier 15, and the back plate 16 It is configured to include a brake pad 17 is coupled to the front surface of the piston 13 to generate a braking force by the friction force while pressing both sides of the disk 23 when the piston 13 is operated using the hydraulic force.
여기서, 상기 캘리퍼하우징(11)에는 휠실린더(12)와 피스톤(13)사이의 기밀을 유지시키기 위한 실링부재(21)가 고정되도록 장착된다.Here, the caliper housing 11 is mounted so that the sealing member 21 for holding the airtight between the wheel cylinder 12 and the piston 13 is fixed.
따라서, 운전자가 제동력을 발생시키기 위해 브레이크페달을 밟아주게 되면 마스터실린더에 압력이 가해지면서 휠실린더(12)의 내부로 유압이 밀려들어와 피스톤(13)을 밖으로 밀어내게 된다.Therefore, when the driver presses the brake pedal to generate the braking force, pressure is applied to the master cylinder and the hydraulic pressure is pushed into the wheel cylinder 12 to push the piston 13 out.
이때, 디스크(23)쪽으로 밀려나온 피스톤(13)은 캘리퍼캐리어(15)의 지지구(18)에 위치한 백플레이트(16)를 직선 이동시키게 되고, 이에 따라 백플레이트(16)에 결합된 브레이크패드(17)는 디스크(23)의 일측면과 접촉을 하면서 밀착되게 된다.At this time, the piston 13 pushed out toward the disk 23 linearly moves the back plate 16 located at the support 18 of the caliper carrier 15, and thus the brake pad coupled to the back plate 16. 17 is in close contact with one side of the disk 23.
그리고, 디스크(23)의 일측면과 접촉하여 작동이 멈춘 브레이크패드(17)는 반작용에 의해 휠실린더(12)방향으로 힘을 가하게 되고, 또한 캘리퍼캐리어(15)와 가이드로드(14)를 통해 연결된 캘리퍼하우징(11)은 전체적으로 뒤로 밀려나게 되며, 뒤로 밀려난 캘리퍼하우징(11)은 조임턱(19)측의 백플레이트(16)를 디스크(23)의 타측면쪽으로 밀어주게 된다.In addition, the brake pad 17 which stops working in contact with one side of the disk 23 exerts a force in the direction of the wheel cylinder 12 by reaction, and also through the caliper carrier 15 and the guide rod 14. The connected caliper housing 11 is pushed back as a whole, and the caliper housing 11 pushed back pushes the back plate 16 of the tightening jaw 19 toward the other side of the disk 23.
이에 따라, 상기 백플레이트(16)에 결합된 나머지의 브레이크패드(17)도 디스크(23)의 타측면과 접촉을 하면서 밀착되게 되며, 이로 인해 회전을 하고 있던 디스크(23)는 브레이크패드(17)와의 접촉시 발생하는 마찰제동력에 의해 회전이 멈춰지게 된다.Accordingly, the rest of the brake pads 17 coupled to the back plate 16 also come into close contact with the other side of the disk 23, and thus the disk 23 that is rotating is brake pads 17. The rotation is stopped by the friction braking force generated when contacting
한편, 상기와 같은 디스크브레이크는 피스톤(13)에 의해 돌출되던 브레이크패드(17)가 도 3에 도시된 바와 같이 디스크(23)의 일면에 접촉할 때 상기 브레이크패드(17)에는 디스크(23) 회전방향(도시된 화살표 R)으로의 전단력(F)이 발생하게 되며, 이 전단력(F)은 결국 백플레이트(16) 및 피스톤(13)을 회전중심(C)을 기준으로 도시된 상태에서 시계방향으로 회전시키려는 회전모멘트(M)로 발전하게 된다.On the other hand, the disk brake as described above, the brake pad 17 protruding by the piston 13 is in contact with the one surface of the disk 23, as shown in FIG. Shear force F in the direction of rotation (arrow R shown) will occur, which in turn will cause the backplate 16 and piston 13 to be clocked in the state shown relative to the center of rotation C. It is developed to the rotation moment (M) to rotate in the direction.
여기서, 상기 회전중심(C)은 피스톤(13)의 중심을 축방향으로 연결한 일직선(L1)과 이에 수직한 방향으로 실링부재(21)를 관통하는 일직선(L2)이 서로 교차되는 부위이다.Here, the center of rotation (C) is a portion where the straight line (L1) connecting the center of the piston 13 in the axial direction and the straight line (L2) passing through the sealing member 21 in a direction perpendicular thereto cross each other.
따라서, 상기와 같은 종래의 디스크브레이크는 제동시 발생하는 회전모멘트(M)에 의해 브레이크패드(17)의 편마모를 유발시키게 되며, 상기와 같은 브레이크패드(17)의 편마모는 결국 중고속 주행중 제동시 디스크(23)의 흔들림이나 또는 조향핸들 및 대시패널에서 발생하는 심한 소음 및 진동의 원인이 되는 저더(juder)로 발전하는 문제점이 있었다.Therefore, the conventional disc brake as described above causes the wear of the brake pad 17 by the rotation moment M generated during braking, and the wear of the brake pad 17 as described above eventually causes the braking during the high-speed driving. There has been a problem in that the disc 23 develops to juder, which is a cause of severe noise and vibration occurring in the steering wheel or the steering wheel and the dash panel.
상기와 같은 회전모멘트(M)의 크기는 브레이크패드(17)의 마모량에 비례하여 점진적으로 커지는 특성을 갖게 되며, 이에 따라 브레이크패드(17)의 교체시기가 늦어질수록 정도가 심한 저더현상이 발생하게 된다.The size of the rotation moment (M) as described above has a characteristic that gradually increases in proportion to the amount of wear of the brake pad 17, accordingly, the more severe the lower the phenomenon occurs as the replacement time of the brake pad 17 is delayed Done.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 피스톤과 연동하여 돌출되는 브레이크패드가 디스크와의 접촉을 통해 제동력을 발생시킬 때 상기 피스톤에 발생하는 회전모멘트를 최대한 억제시킬 수 있도록 함으로써, 상기 브레이크패드의 편마모를 감소시키고 이로 인해 제동안정성을 증대시킬 수 있도록 함은 물론 제동시 발생하는 저더현상을 감소시킬 수 있도록 하는 자동차의 디스크브레이크 구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, by allowing the brake pad protruding in conjunction with the piston to suppress the rotation moment generated in the piston when generating a braking force through contact with the disc as much as possible In addition, the object of the present invention is to provide a disc brake structure of a vehicle that can reduce uneven wear of the brake pad and thereby increase determinism during braking, as well as reduce judging generated during braking.
상기와 같은 목적을 달성하기 위한 본 발명의 디스크브레이크는, 휠실린더의 안쪽을 향하는 피스톤의 후방부 외주면에 끼워지면서 그 둘레면이 상기 휠실린더와 접촉하도록 설치되는 댐퍼링을 포함하여 구성되는 것을 특징으로 한다.Disc brake of the present invention for achieving the above object is characterized in that it comprises a damper ring is installed so that the circumferential surface is in contact with the wheel cylinder while being fitted to the outer peripheral surface of the rear portion of the piston facing inward of the wheel cylinder. It is done.
이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 4는 본 발명에 따라 피스톤에 댐퍼링이 결합된 디스크브레이크를 설명하기 위한 종단면도로서, 종래 구조와 동일한 부위에는 동일한 참조부호를 붙이면서 설명하기로 한다.Figure 4 is a longitudinal sectional view for explaining a disc brake coupled to the piston in accordance with the present invention, will be described with the same reference numerals to the same parts as the conventional structure.
본 발명은 디스크브레이크를 구성하는 피스톤에 댐퍼링을 결합시켜 제동력 발생시 상기 피스톤의 회전모멘트를 최대한 억제시킬 수 있도록 하는 구성이다.The present invention is configured to couple the damper ring to the piston constituting the disc brake to suppress the rotation moment of the piston as much as possible when braking force is generated.
즉, 디스크브레이크의 구조는 전술하였던 바와 같이, 주철재질의 안장모양으로 형성되어 너클스핀들에 부착되는 캘리퍼하우징(11)과, 이 캘리퍼하우징(11)에 의해 형성된 휠실린더(12)내에 장착되면서 유압의 힘을 이용해 직선으로 이동하는 피스톤(13)과, 상기 캘리퍼하우징(11)의 전면에 가이드로드(14)를 매개로 결합되는 캘리퍼캐리어(15)와, 양측면에 형성된 슬라이드돌기(16a)가 상기 캘리퍼캐리어(15)에 형성된 슬라이드홈(15a)으로 끼워짐으로써 상기 캘리퍼캐리어(15)와 결합되는 백플레이트(16)와, 이 백플레이트(16)의 전면에 결합되어 상기 피스톤(13)이 유압의 힘을 이용해 작동될 때 디스크(23)의 양측면을 가압하면서 마찰력에 의한 제동력을 발생시키도록 하는 브레이크패드(17)를 포함하여 구성된다.That is, the structure of the disc brake, as described above, is mounted in the caliper housing 11 formed in the saddle shape of the cast iron material and attached to the knuckle spindle, and mounted in the wheel cylinder 12 formed by the caliper housing 11, The piston 13 to move in a straight line using the force of the caliper housing 11, the caliper carrier 15 is coupled to the front of the caliper housing 11 via the guide rod 14, the slide projections 16a formed on both sides are The back plate 16 is coupled to the caliper carrier 15 by being fitted into the slide groove 15a formed in the caliper carrier 15, and is coupled to the front surface of the back plate 16 so that the piston 13 is hydraulically operated. It is configured to include a brake pad 17 for generating a braking force by the friction force while pressing the two sides of the disk 23 when operated using the force of.
여기서, 상기 캘리퍼하우징(11)에는 휠실린더(12)와 피스톤(13)사이의 기밀을 유지시키기 위한 실링부재(21)가 고정되도록 장착된다.Here, the caliper housing 11 is mounted so that the sealing member 21 for holding the airtight between the wheel cylinder 12 and the piston 13 is fixed.
또한, 본 발명에 따른 디스크브레이크는 도 4와 도 5에 도시된 바와 같이 댐퍼링(30)을 더 포함하여 구성되는데, 상기 댐퍼링(30)은 휠실린더(12)의 안쪽을 향하는 피스톤(13)의 후방부에서 외주면에 끼워짐으로써 결합되고, 또한 댐퍼링(30)의 둘레면(외주면)은 상기 피스톤(13)이 휠실린더(12)내에 설치될 때 상기 휠실린더(12)와 접촉하도록 설치된다.In addition, the disc brake according to the present invention further comprises a damper ring 30 as shown in Figures 4 and 5, the damper ring 30 is a piston 13 toward the inside of the wheel cylinder 12 Is engaged by being fitted to the outer circumferential surface at the rear portion of the head), and the circumferential surface (outer circumferential surface) of the damper ring 30 is brought into contact with the wheel cylinder 12 when the piston 13 is installed in the wheel cylinder 12. Is installed.
이에 따라, 상기 피스톤(13)에는 댐퍼링(30)이 끼워지는 결합홈(13a)이 둘레면(외주면)을 따라 형성된다.Accordingly, the piston 13 is formed along the circumferential surface (outer circumferential surface) with a coupling groove 13a into which the damper ring 30 is fitted.
한편, 상기 댐퍼링(30)은 결합홈(13a)에 끼워지기 위해서는 탄성을 구비하고 있어야 하며, 이를 위해서는 고무댐퍼를 사용하는 것이 가장 바람직하다.On the other hand, the damper ring 30 should be provided with an elastic to fit in the coupling groove (13a), for this purpose it is most preferable to use a rubber damper.
또한, 상기 댐퍼링(30)은 제동력 발생시 휠실린더(12)내의 브레이크오일 압력에 의해 상기 결합홈(13a)으로부터 이탈되거나 또는 그 형상이 크게 변형되지 않아야 되는 바, 이를 달성하기 위해서 상기 댐퍼링(30)은 그 둘레면(외주면)이 원주방향을 따라 물결모양으로 형성되는 구조를 갖게 된다.In addition, the damper ring 30 should not be separated from the coupling groove 13a or greatly deformed by the brake oil pressure in the wheel cylinder 12 when the braking force is generated. 30 has a structure in which the circumferential surface (outer circumferential surface) is formed in a wave shape along the circumferential direction.
여기서, 상기 댐퍼링(30)의 둘레면이 물결모양으로만 한정되는 것이 아니라, 휠실린더(12)내의 브레이크오일이 원활하게 통과할 수만 있다면 다양한 모양으로 형성될 수도 있음은 물론이다.Here, the circumferential surface of the damper ring 30 is not limited to a wave shape, but may be formed in various shapes as long as the brake oil in the wheel cylinder 12 can pass smoothly.
따라서, 제동력 발생시 피스톤(13)과 함께 돌출되어 디스크(23)의 일면에 접촉하는 브레이크패드(17)에는 도 6에 도시된 바와 같이 디스크(23) 회전방향(도시된 화살표 R)으로의 전단력(F)이 발생하게 된다.Therefore, when the braking force is generated, the brake pad 17 protruding with the piston 13 and contacting one surface of the disk 23 has a shear force in the direction of rotation of the disk 23 (arrow R shown) as shown in FIG. F) is generated.
또한, 상기의 전단력(F)에 의해 백플레이트(16)를 포함한 피스톤(13)에는 회전중심(C)을 기준으로 하여 도시된 상태에서 시계방향으로 회전되려는 회전모멘트(M)가 발생하게 된다.In addition, the piston 13 including the back plate 16 by the shear force (F) will generate a rotation moment (M) to be rotated clockwise in the state shown on the basis of the center of rotation (C).
그러나, 피스톤(13)에 발생하는 상기의 회전모멘트(M)는 본 발명에 따른 댐퍼링(30)이 휠실린더(12)와의 접촉을 통해 발생하는 지지력(P)에 의해 최대한 억제되게 된다.However, the rotation moment M generated in the piston 13 is suppressed as much as possible by the bearing force P generated by the damper ring 30 according to the present invention in contact with the wheel cylinder 12.
즉, 상기 댐퍼링(30)에 의해 발생되는 지지력(P)은 상기 회전모멘트(M)의 진행방향과는 서로 반대되는 힘을 갖게 되며, 이에 따라 상기 피스톤(13)의 회전모멘트(M)는 댐퍼링(30)의 지지력(P)에 의해 억제되는 것이다.That is, the bearing force P generated by the damper ring 30 has a force opposite to the direction of travel of the rotation moment M. Accordingly, the rotation moment M of the piston 13 is This is suppressed by the bearing force P of the damper ring 30.
이와 같이, 제동력이 발생할 때 피스톤(13)의 회전모멘트(M)가 본 발명에 따른 댐퍼링(30)에 의해 최대한 억제되면, 디스크(23)와 접촉하는 브레이크패드(17)의 편마모를 감소시킬 수가 있게 되며, 또한 중고속 주행중 제동시 디스크(23)의 흔들림이나 또는 조향핸들 및 대시패널에서 발생하는 심한 소음 및 진동의 원인이 되는 저더(juder)현상도 감소시킬 수가 있게 된다.In this way, if the rotation moment M of the piston 13 is suppressed as much as possible by the damper ring 30 according to the present invention when the braking force is generated, it is possible to reduce the uneven wear of the brake pad 17 in contact with the disk 23. In addition, it is also possible to reduce the judder phenomenon which causes the shaking of the disc 23 or the severe noise and vibration generated from the steering wheel and the dash panel during braking during the high speed driving.
이상 설명한 바와 같이 본 발명에 의하면, 제동력 발생시 피스톤에 발생하는 회전모멘트가 댐퍼링에 의해 억제됨으로써, 브레이크패드의 편마모가 감소되어 제동안정성이 증대됨은 물론, 제동소음 및 이상진동현상을 최대한 감소시킬 수 있게 되어 차량의 고급화에 도움이 되는 효과가 있게 된다.As described above, according to the present invention, the rotational moment generated in the piston at the time of braking force is suppressed by the damper ring, thereby reducing the uneven wear of the brake pads, thereby increasing the reliability of the brake pads as well as reducing the braking noise and abnormal vibration phenomenon as much as possible. This will help to improve the quality of the vehicle.
