Description
본 발명은 작동소음저감기능을 갖는 차량 브레이크용 캘리퍼에 관한 것으로, 보다 상세하게는 결합부위의 금속마찰을 제거한 작동소음저감기능을 갖는 차량 브레이크용 캘리퍼에 관한 것이다.The present invention relates to a caliper for a vehicle brake having an operation noise reduction function, and more particularly, to a caliper for a vehicle brake having an operation noise reduction function in which metal friction of a coupling portion is removed.
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 조작 시 차량을 제동하기 위해 직접회전하는 바퀴의 로터와 마찰하는 부분으로서, 이는 도 1에 도시된 바와 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.That is, the caliper is a part that rubs against the rotor of the wheel that rotates directly to brake the vehicle during brake operation, which surrounds the rotor of the wheel as shown in FIG. 1 to stop the rotor during brake operation. It consists of a housing (1) having a built-in and a carrier (2) coupled to the housing (1) to maintain a gap with the rotor of the wheel and to mount a caliper to the knuckle (Knuckle), the housing (1) and the carrier ( 2) is coupled by a guide rod 3 of steel material.
즉, 상기 하우징(1)의 삽입홀(1a)을 통해 삽입된 가이드로드(3)가 캐리어(2)와 결합되되, 이 가이드로드(3)는 도 2에 도시된 바와 같이 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), the guide rod (3) of the housing 1 as shown in FIG. It is wrapped by the boot 4 fixed to the protruding seating end (1b).
그러나, 이와 같이 부트(4)가 하우징(1)의 안착단(1b)을 매개로 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, 약0.14mm이하임, 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 via the seating end 1b of the housing 1, the guide rod 3 and the insertion hole 1a of the housing 1 are directly Since the caliper is also flowed by the wheel that moves up and down during irregular road driving, the gap between the insertion hole 1a of the housing 1 and the guide rod 3 inserted therein, about 0.14 mm or less, Thereby, 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, both the guide rod 3 and the housing 1 are made of a metal 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.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 가이드로드와 하우징을 감싸고 있는 고무재질의 부트를 매개로 하우징과 가이드의 금속성 마찰을 방지하여 차륜의 상·하로 유동시 금속성 마찰음의 발생을 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and prevents metallic friction between the housing and the guide through the boot of the rubber material surrounding the guide rod and the housing, thereby preventing the occurrence of metallic friction noise when the vehicle moves up and down the wheel. The purpose is to prevent.
상기와 같은 목적을 달성하기 위한 본 발명은, 차륜의 로터를 감싸 브레이크 조작시 로터를 정지시키는 하우징과, 이 하우징에 결합되어 차륜의 로터와 간격을 유지하는 캐리어 및 이 하우징에 형성된 삽입홀의 안쪽으로 형성된 안착단에 결합 고정된 부트에 의해 감싸여져 캐리어와 결합되는 스틸재질의 가이드로드로 구성되는 것을 특징으로 한다.The present invention for achieving the above object, the housing surrounding the rotor of the wheel to stop the rotor during the brake operation, the carrier coupled to the housing to maintain a distance from the rotor of the wheel and the insertion hole formed in the housing It is characterized by consisting of a guide rod of a steel material is wrapped by a fixed boot coupled to the seating end is coupled to the carrier.

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 3은 본 발명에 따라 작동소음저감기능을 갖는 캘리퍼의 결합단면도를 도시한 것인바, 본 발명은 차륜의 로터를 감싸 브레이크 조작시 로터를 정지시키도록피스톤과 챔버등을 내장한 하우징(1)과, 이 하우징(1)에 결합되어 차륜의 로터와 간격을 유지하며 캘리퍼를 너클에 장착하는 캐리어(2) 및 이 하우징(1)과 캐리어(2)를 결합하는 스틸재질의 가이드로드(3)로 구성되되, 이 가이드로드(3)는 상기 하우징(1)의 삽입홀(1a)을 통해 삽입됨과 더불어 상기 하우징(1)의 삽입홀(1a)의 안쪽으로 형성된 안착단(1b)에 결합 고정된 부트(4)에 의해 감싸여 지게 된다.Figure 3 shows a combined cross-sectional view of the caliper having a function of reducing the operation noise in accordance with the present invention, the present invention is a housing (1) with a built-in piston and chamber to surround the rotor of the wheel to stop the rotor during brake operation And a carrier (2) coupled to the housing (1) to maintain a gap with the rotor of the wheel and for mounting a caliper to the knuckle, and a guide rod (3) of steel material for coupling the housing (1) and the carrier (2). The guide rod (3) is inserted through the insertion hole (1a) of the housing (1) and fixedly coupled to the seating end (1b) formed inward of the insertion hole (1a) of the housing (1) It is wrapped by the boot 4.
이에 따라, 상기 부트(4)가 하우징(1)의 삽입홀(1a)의 내면으로 형성된 안착단(1b)에 삽입 결합되어 하우징(1)과 가이드로드(3)를 외부에서 감싸게 되면, 외부로부터 침투되는 이물질의 유입을 방지함과 더불어 가이드로드(3)와 하우징(1)의 삽입홀(1a)이 고무재질의 부트(4)를 매개로 간접 접촉되므로 불규칙한 노면 주행시 상·하로 유동되는 차륜에 의해 캘리퍼도 함께 유동되더라도, 상기 하우징(1)의 삽입홀(1a)과 이에 삽입된 가이드로드(3)가 삽입홀(1a)내에서 유동되지 않게 된다.Accordingly, when the boot 4 is inserted and coupled to the seating end 1b formed as the inner surface of the insertion hole 1a of the housing 1 to surround the housing 1 and the guide rod 3 from the outside, In addition, the guide rod 3 and the insertion hole 1a of the housing 1 are indirectly contacted with each other via the boot 4 made of rubber material. Even when the caliper flows together, the insertion hole 1a of the housing 1 and the guide rod 3 inserted therein do not flow in the insertion hole 1a.
이상 설명한 바와 같이 본 발명에 의하면, 가이드로드와 하우징을 감싸고 있는 고무재질의 부트가 하우징의 안쪽으로 구비되어 차륜의 상·하 유동시 하우징과 가이드의 금속성 마찰을 방지하는 효과가 있게 된다.As described above, according to the present invention, a rubber boot surrounding the guide rod and the housing is provided inside the housing, thereby preventing metallic friction between the housing and the guide when the wheel moves up and down.
