Description

차량 브레이크용 캘리퍼의 결합구조{CONNECTING STRUCTURE OF BRAKE CALIPER IN A CAR}CONNECTING STRUCTURE OF BRAKE CALIPER IN A CAR}

본 발명은 차량 브레이크용 캘리퍼의 결합구조에 관한 것으로, 보다 상세하게는 결합부위의 금속마찰로 인해 발생되는 소음을 제거함과 아울러, 가이드로드 핀의 복귀성능을 향상시킬 수 있도록 그 구조가 개량된 차량 브레이크용 캘리퍼의결합구조에 관한 것이다.The present invention relates to a coupling structure of a caliper for a vehicle brake, and more particularly, to improve the return performance of a guide rod pin while removing noise generated by metal friction of the coupling portion. A coupling structure of a brake caliper is provided.

일반적으로, 주행중인 차량을 정지시키기 위한 브레이크 장치는 유압을 이용하여 제동력을 발휘하는 유압브레이크장치로서, 통상 브레이크페달과, 부스터, 마스터실린더, 비례밸브, 전·후방브레이크 어셈블리로 구성되어 진다.In general, a brake device for stopping a running vehicle is a hydraulic brake device that exerts a braking force using hydraulic pressure, and is generally composed of a brake pedal, a booster, a master cylinder, a proportional valve, and a front / rear brake assembly.

이와 같은 브레이크 장치는 운전자가 차량을 정지시키고자 브레이크 페달을 밟게 되면, 이 페달의 기구학적인 구조에 의해 힘이 증폭된 상태에서 다시 부스터를 통해 2차적인 힘의 증가를 거치면서 마스터실린더가 이를 유압으로 변환시켜 비례밸브를 통해 각 바퀴의 브레이크 어셈블리의 캘리퍼로 전달되어 회전하고 있는 로터를 가압하여 제동력을 발생시키게 된다.When the driver presses the brake pedal to stop the vehicle, the master cylinder receives hydraulic pressure through the booster while the power is amplified by the pedal's kinematic structure. By converting the pressure into the caliper of the brake assembly of each wheel through a proportional valve to pressurize the rotating rotor to generate a braking force.

즉, 이러한 캘리퍼는 브레이크 조작시 차량을 제동하기 위해 직접회전하는 바퀴의 로터와 마찰하는 부분으로서, 캘리퍼형 브레이크는 통상적으로 브레이크 실린더를 2개 두어 디스크의 양측에서 패드를 압착시켜 제동하는 방식의 대향 피스톤형과, 캘리퍼의 한쪽에만 1개의 브레이크 실린더를 두고 마스터실린더의 유압이 작용하면 피스톤이 패드를 압착함과 아울러 그 반발력으로 캘리퍼를 이동시켜 반대쪽의 패드를 디스크에 압착시켜 제동하는 부동캘리퍼형(싱글 실린더 플로팅 캘리퍼 타입)으로 구분된다.That is, the caliper is a portion that rubs against the rotor of the wheel that rotates directly to brake the vehicle when the brake is operated, and the caliper brake normally has two brake cylinders to squeeze the pads on both sides of the disk to brake the opposite. When the hydraulic pressure of the master cylinder is applied with one brake cylinder on one side of the piston and the caliper, the piston squeezes the pad and the caliper moves by the repulsive force to press the pad on the opposite side to the disk to brake. Single cylinder floating caliper type).

그 부동 캘리퍼방식은 도 3 및 도 4에서와 같이 차륜의 로터를 감싸 브레이크 조작시 로터를 정지시키도록 피스톤과 챔버등을 내장한 하우징(1)과, 이 하우징(1)에 결합되어 차륜의 로터와 간격을 유지하며 캘리퍼를 너클(Knuckle)에 장착하는 캐리어(2)로 구성되되, 이 하우징(1)과 캐리어(2)는 스틸재질의 가이드로드(3)에 의해 결합되어진다.3 and 4, the floating caliper method surrounds the rotor of the wheel and includes a housing 1 incorporating a piston, a chamber, and the like to stop the rotor during brake operation, and is coupled to the housing 1 to the rotor of the wheel. It is composed of a carrier (2) for maintaining the distance between the caliper to the knuckle (Knuckle), the housing (1) and the carrier (2) is coupled by a guide rod (3) made of steel.

즉, 상기 하우징(1)의 삽입홀(1a)을 통해 삽입된 가이드로드(3)가 캐리어(2)와 결합되고, 이 가이드로드(3)는 하우징(1)의 돌출된 안착단(1b)에 결합 고정된 부트(4)에 의해 감싸여지게 된다.That is, the guide rod 3 inserted through the insertion hole 1a of the housing 1 is coupled to the carrier 2, and the guide rod 3 is a protruding seating end 1b of the housing 1. It is wrapped by a fixed boot (4) coupled to.

그러나, 이와 같이 부트(4)가 하우징(1)의 안착단(1b)을 중심으로 하우징(1)의 외부에서 감싸게 되면, 가이드로드(3)와 하우징(1)의 삽입홀(1a)이 직접 접촉되므로 불규칙한 노면 주행시 상·하로 유동되는 차륜에 의해 캘리퍼도 함께 유동되고 이에 따라, 하우징(1)의 삽입홀(1a)과 이에 삽입된 가이드로드(3)사이의 틈(약 0.14mm이하)에 의해 가이드로드(3)가 삽입홀(1a)내에서 유동되는 문제가 있게 된다.However, when the boot 4 is wrapped around the outside of the housing 1 around the seating end 1b of the housing 1, the guide rod 3 and the insertion hole 1a of the housing 1 are directly The calipers are also flown together by the wheels that move up and down during irregular road driving, so that the gap (between about 0.14 mm or less) between the insertion hole 1a of the housing 1 and the guide rod 3 inserted therein. As a result, there is a problem that the guide rod 3 flows in the insertion hole 1a.

또한, 이와 같이 가이드로드(3)가 하우징(1)의 삽입홀(1a)내에서 상,하로 유동되면, 가이드로드(3)와 하우징(1)이 모두 금속재질로 이루어져 덜거덩거리는 금속성 마찰음이 발생될 뿐만 아니라 지속적인 마찰로 인해 허용되는 틈 간격을 초과하여 그 교환시기가 빨라지는 단점이 있게 된다.In addition, when the guide rod 3 flows up and down in the insertion hole 1a of the housing 1 as described above, the guide rod 3 and the housing 1 are made of a metallic material, so that a metallic rubbing noise is generated. In addition, there is a disadvantage that the replacement time is faster than the allowable gap interval due to the constant friction.

이를 극복하기 위해 가이드로드(3)의 단부에 고무재질의 부싱(7)이 결합되어 삽입홀(1a)의 내주면 사이에 개재되어 있다.In order to overcome this, the rubber bushing 7 is coupled to the end of the guide rod 3 and interposed between the inner circumferential surfaces of the insertion hole 1a.

한편, 상기한 문제점들을 개선하기 위한 선행기술의 다른 예로는 미국 특허번호 US005730258A호에 개시되고, 그 구조는 내주면에 복수개의 주름을 갖는 고무 부싱이 가이드로드와 삽입홀 사이에 개재 설치된 것이다.On the other hand, another example of the prior art for improving the above problems is disclosed in US Patent No. US005730258A, the structure is a rubber bushing having a plurality of corrugations on the inner peripheral surface is interposed between the guide rod and the insertion hole.

이는 고무 부싱의 외주면이 삽입홀의 내주면에 길게 접촉되도록 삽입된 구조를 가지며, 그 고무 부싱이 수분의 유입을 방지하고 부식에 의해 가이드로드가 삽입홀에 고착되는 것을 방지하는 기능을 갖는 것이다.It has a structure in which the outer circumferential surface of the rubber bushing is inserted into long contact with the inner circumferential surface of the insertion hole, and the rubber bushing has a function of preventing the inflow of water and preventing the guide rod from being fixed to the insertion hole by corrosion.

그런데, 상기한 구조를 갖는 종래 선행기술은 가이드로드가 삽입홀에 삽입된 상태에서 브레이크를 밟게 될때 슬라이딩되는 구조를 가지고 있으므로, 연속적인 브레이크 제동동작시 온도 상승에 의해 고무 부싱이 팽창하게 되고, 이에 따라 가이드로드와 삽입홀 사이에 저항이 발생하게 될 뿐만 아니라, 팽창된 고무 부싱이 삽입홀의 내주면에 밀착되어 가이드로드가 삽입홀에 고착되는 문제점이 있었다.However, since the prior art having the above structure has a structure that slides when the guide rod is inserted into the insertion hole when the brake is pressed, the rubber bushing is expanded by the temperature rise during the continuous brake braking operation. Accordingly, not only resistance between the guide rod and the insertion hole is generated, but the expanded rubber bushing is in close contact with the inner circumferential surface of the insertion hole, so that the guide rod is fixed to the insertion hole.

또한, 상기한 가이드로드가 삽입홀에 고착될 경우, 브레이크가 계속 작동되는 효과와 동일하므로, 브레이크의 온도가 계속 상승되어 브레이크 마찰재가 조기 마모될 우려가 있을 뿐만 아니라, 심하게는 차량의 화재요인으로 작용하게 될 우려가 있었다.In addition, when the guide rod is fixed to the insertion hole, the same as the effect that the brake continues to operate, the temperature of the brake is continuously increased, there is a risk of premature wear of the brake friction material, severely caused by the fire of the vehicle There was a risk of working.

본 발명은 상기한 제반문제점을 감안하여 이를 해결하고자 안출된 것으로, 그 목적은 가이드로드와 삽입홀 사이에 마찰 소음을 줄이는 본연의 기능을 가지고, 연속적인 브레이크 제동시 고무 부싱이 온도 상승에 대한 팽창력이 발생하더라도 삽입홀에 고착되는 것을 방지함과 아울러, 가이드로드의 복원력을 보조할 수 있도록 그 구조가 개선된 차량 브레이크용 캘리퍼의 결합구조를 제공하는 데 있다.The present invention has been made to solve the above problems in view of the above problems, the purpose of which has the inherent function of reducing friction noise between the guide rod and the insertion hole, the rubber bushing in the continuous brake braking when the expansion force for temperature rise The present invention provides a coupling structure of a caliper for a vehicle brake in which the structure is improved to prevent fixation to the insertion hole and to assist the restoring force of the guide rod even when this occurs.

본 발명의 다른 특징은 상기 씰링재는 상기 가이드로드의 슬라이딩동작시 변형 및 복원되도록 적정 탄성력을 갖는 고무재질인 것이다.Another feature of the present invention is that the sealing material is a rubber material having an appropriate elastic force to be deformed and restored during the sliding operation of the guide rod.

본 발명의 또 다른 특징은 상기 요홈이 상기 씰링재의 테두리가 지지되는 내측면의 내측으로 공간부가 연장 형성된 것이다.Another feature of the present invention is that the groove is formed in the space portion is extended to the inner side of the inner surface that the edge of the sealing material is supported.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 하되, 앞서 설명한 종래 기술과 동일 구성요소에 대해서는 동일 부호를 기재하고, 중복되는 설명은 생략하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals are used for the same elements as the prior art described above, and redundant descriptions will be omitted.

본 발명에 따른 차량 브레이크용 캘리퍼의 결합구조는, 도 1 및 도 2를 참조하여 설명하면, 그 구성은 캘리퍼 하우징(1)의 일측에 삽입홀(1a)이 형성되고, 그 삽입홀(1a)에 브레이크 제동시 슬라이딩 동작되는 가이드로드(3)가 수용되며, 그 가이드로드(3)의 단부 외주면에 적정 간격으로 복수개의 씰링재(20)가 상호 이격되도록 끼움 결합되어 있다.When the coupling structure of the vehicle brake caliper according to the present invention is described with reference to Figs. 1 and 2, the configuration is that an insertion hole 1a is formed at one side of the caliper housing 1, and the insertion hole 1a is provided. The guide rod 3 is slid when the brake is braked, and the plurality of sealing materials 20 are fitted to the outer peripheral surface of the end of the guide rod 3 so as to be spaced apart from each other.

더 상세히 설명하면, 그 씰링재(20)는 중앙에 중공을 갖는 링형상을 가지며, 그 삽입홀(1a)의 내주면에 복수개 형성된 요홈(11) 내에 수용되어 지지되고, 브레이크 동작에 의해 슬라이딩되는 가이드로드(3)의 동작에 연동되어 변형되는 특성을 갖는다.In more detail, the sealing material 20 has a ring shape having a hollow in the center, and is received and supported in a plurality of grooves 11 formed on the inner circumferential surface of the insertion hole 1a, and is supported by a sliding guide rod. It has a characteristic of being deformed in conjunction with the operation of (3).

또한, 그 씰링재(20)는 가이드로드(3)의 복귀동작시 복원력을 부여하도록 자체 복원 탄성력을 갖는 고무재질을 채용하는 것이 바람직하다.In addition, the sealing material 20 is preferably a rubber material having a self-resilience elastic force to give a restoring force in the return operation of the guide rod (3).

그리고, 삽입홀(1a)의 내주면에 형성된 요홈(11)은 상기한 씰링재(20)의 테두리가 수용되도록 환형으로 형성되어 있으며, 그 씰링재(20)의 테두리가 지지되는 내주면의 내측으로 적정 공간의 공간부(11a)가 연장 형성되어 있다.In addition, the recess 11 formed in the inner circumferential surface of the insertion hole 1a is formed in an annular shape so that the edge of the sealing material 20 is accommodated, and the inner space of the proper space is supported inside the inner circumferential surface of the edge of the sealing material 20. The space part 11a is extended.

이 공간부(11a)는 브레이크의 연속동작시 온도가 상승될 경우, 씰링재(20)의 팽창에 따른 여유공간을 두기 위함이며, 대략적인 단면형상이 씰링재(20)의 테두리와 간섭되는 것을 방지하도록 사다리꼴 형상으로 이루어져 있다.The space portion 11a is to leave a space according to the expansion of the sealing material 20 when the temperature rises during continuous operation of the brake, so as to prevent the rough cross-sectional shape from interfering with the edge of the sealing material 20. It consists of a trapezoidal shape.

미설명부호는 "1b"는 캘리퍼 하우징(1)의 안착단을 나타낸 것이고, "4"는 그 안착단(1b)의 외측에 감싸도록 결합되는 고무 부트를 나타낸 것이다.Reference numeral "1b" denotes a seating end of the caliper housing 1, and "4" denotes a rubber boot that is coupled to wrap around the outside of the seating end 1b.

이하, 본 고안의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

본 고안의 캘리퍼 결합구조는 그 조립과정이 삽입홀(1a)의 내주면에 형성된 각각의 요홈(11)들에 씰링재(20)를 각각 삽입하고, 이어서 씰링재(20)가 설치된 삽입홀(1a)에 가이드로드(3)를 삽입하여 그 씰링재(20)의 중공측으로 관통시키는 공정을 갖는다.In the caliper coupling structure of the present invention, the assembling process inserts the sealing material 20 into each of the recesses 11 formed in the inner circumferential surface of the insertion hole 1a, and then into the insertion hole 1a in which the sealing material 20 is installed. The guide rod 3 is inserted and penetrated to the hollow side of the sealing material 20.

이에 따라, 씰링재(20)는 가이드로드(3)의 외주면과 삽입홀(1a)의 내주면 사이의 틈새에 개재되어 설치되므로, 가이드로드(3)의 브레이크 동작시 삽입홀(1a)과 직접 마찰되는 것을 방지하여 금속 마찰에 의한 노이즈발생을 억제할 수 있게 된다.Accordingly, the sealing material 20 is interposed between the outer circumferential surface of the guide rod 3 and the inner circumferential surface of the insertion hole 1a, so that the sealing member 20 is directly rubbed with the insertion hole 1a during the brake operation of the guide rod 3. It is possible to prevent the occurrence of noise due to the metal friction by preventing it.

그리고, 조립공정이 완료된 후에 브레이크가 작동될 경우, 하우징(1)의 이동에 따라 브레이크 패드(미도시됨)가 디스크에 압착하게 되고, 이때 가이드로드(3)가 하우징(1)의 이동방향과 같은 방향으로 연동하게 된다.In addition, when the brake is operated after the assembly process is completed, the brake pad (not shown) is pressed onto the disk according to the movement of the housing 1, and the guide rod 3 is connected to the moving direction of the housing 1. It will work in the same direction.

그 브레이크의 반복 동작시 온도가 상승하게 됨에 따라, 씰링재(20)의 부피 또한 팽창되어 그 테두리부위가 요홈(11)의 공간부(11a)측으로 수용됨과 아울러, 그 가이드로드(3)의 단부 외주면에 결합된 씰링재(20)는 가이드로드(3)의 이동에 따라 탄성변형의 범위내에서 변형되고, 이후에 브레이크 작동이 완료된 후에는 다시 자체 복원력에 의해 원래의 형태로 복원된다.As the temperature rises during the repetitive operation of the brake, the volume of the sealing material 20 is also expanded so that the edge portion is accommodated in the space portion 11a of the groove 11 and the outer peripheral surface of the end portion of the guide rod 3. Sealing material 20 coupled to the deformed in the range of elastic deformation in accordance with the movement of the guide rod (3), and after the brake operation is completed is restored back to its original form by the self restoring force again.

그 씰링재(20)는 복원시 가이드로드(3)의 외주면에 접촉되어 있으므로, 가이드로드(3)에 복원력을 부여하게 되어 가이드로드(3)의 복귀동작을 보조하게 된다.Since the sealing material 20 is in contact with the outer circumferential surface of the guide rod 3 at the time of restoration, the restoring force is applied to the guide rod 3 to assist the return operation of the guide rod 3.

한편, 브레이크 작동이 완료된 후에 원래의 온도로 복원되면, 씰링재(20)는 다시 원래의 부피대로 수축되므로, 요홈(11)의 공간부(11a)측으로부터 벗어나게 된다.On the other hand, if the restoring to the original temperature after the brake operation is completed, since the sealing material 20 is shrunk back to the original volume, it is out of the space portion (11a) side of the groove (11).

이에 따르면, 본 발명의 가이드로드(3)는 브레이크 동작이 완료된 후에 씰링재(20)의 자체 복원탄성력에 의해 원 위치로 복귀하는 힘이 배가되어 복귀동작이 원활하게 이루어지게 된다.According to this, the guide rod 3 of the present invention doubles the force returning to the original position by the self-resilient elastic force of the sealing material 20 after the brake operation is completed, the smooth return operation is made.

이상과 같이 설명한 본 발명은 캘리퍼의 씰링구조를 개선하여 브레이크의 연속동작에 의해 온도가 상승하더라도 고착에 따른 오동작을 예방할 수 있도록 한 것인 바, 이에 따르면 본 발명은 브레이크 작동후 가이드로드의 복귀동작을 보조할 수 있을 뿐만 아니라, 브레이크의 연속동작에 따른 온도가 상승되더라도 가이드로드의 오동작을 방지하여 제품의 신뢰성을 향상시킬 수 있는 유용한 효과를 갖는다.The present invention as described above is to improve the sealing structure of the caliper to prevent a malfunction due to sticking even if the temperature rises by the continuous operation of the brake, according to the present invention, the return operation of the guide rod after the brake operation In addition to assisting, even if the temperature increases due to the continuous operation of the brake has a useful effect to prevent the malfunction of the guide rod to improve the reliability of the product.
