Description

[규칙 제26조에 의한 보정 06.09.2013]　오프셋 보상 구조를 갖는 차량용 디스크 브레이크 [Revision according to Rule 26. 06.09.2013] 차량 Car disc brake with offset compensation structure
본 발명은 오프셋 보상 구조를 갖는 차량용 디스크 브레이크에 관한 것으로, 보다 구체적으로 디스크 브레이크를 제동하기 위해 레버에서 제동력이 인가될 때, 레버의 움직임에 의해 발생되는 오프셋을 보상하기 위한 오프셋 보상 구조를 갖는 차량용 디스크 브레이크에 관한 것이다.The present invention relates to a vehicle disc brake having an offset compensation structure, and more particularly to a vehicle having an offset compensation structure for compensating an offset caused by the movement of the lever when a braking force is applied from the lever to brake the disc brake. Relates to a disc brake.

일반적으로 차량에 장착되는 디스크 브레이크는 차량의 휠과 함께 회전하는 디스크의 양면을 브레이크 패드로 가압함으로써 강제 마찰에 의한 마찰력으로 차량을 제동시키는 장치이다. In general, a disc brake mounted on a vehicle is a device for braking the vehicle by frictional force due to forced friction by pressing both sides of the disk rotating together with the wheel of the vehicle with the brake pads.
디스크 브레이크에는 유압식과 공압식이 있다. 회전 레버를 갖는 공압식 디스크 브레이크에서는 디스크 브레이크를 제동하기 위해 레버에서 트레버스로 제동력이 인가될 때, 레버의 행정에 따라 출력 하중의 높이가 변하므로 브레이크 성능이 불균일해지는 오프셋 문제가 있다. Disc brakes are hydraulic and pneumatic. In a pneumatic disc brake having a rotary lever, when a braking force is applied from the lever to the traverse to brake the disc brake, there is an offset problem in that the brake performance becomes uneven because the height of the output load changes according to the stroke of the lever.
EP 0553105에 개시된 디스크 브레이크에서는 이러한 오프셋 문제와 관련하여 아무런 대책도 가지고 있지 않다. US 7,506,732에 개시된 디스크 브레이크에서는 리브형 롤러를 사용하여 오프셋을 보상하고 있으나, 리브형 롤러의 형상이 복잡하여 제조하기 어렵다는 문제가 있다. US 5,547,048에 개시된 디스크 브레이크에서는 평면 부재에서 롤러가 미끄러져 오프셋을 보상하고 있으나, 롤러와 평면 부재가 선 접촉하므로 국부 마모가 발생할 가능성이 높다.The disc brake disclosed in EP 0553105 has no countermeasure with respect to this offset problem. The disc brake disclosed in US 7,506,732 compensates for offset using a ribbed roller, but there is a problem that the shape of the ribbed roller is complicated and difficult to manufacture. In the disc brake disclosed in US Pat. No. 5,547,048, the roller slides in the flat member to compensate for the offset, but since the roller and the flat member are in linear contact, there is a high possibility of local wear.

That is, the support surface 31 of the offset compensating member 30, which the roller 20 contacts, has an arc shape so as to be in surface contact with the cylindrical roller 20, and an angle formed at both ends of the arc with respect to the center of the arc. Is less than 180 degrees. The contact surface of the traverse 40 that the offset compensation member 30 contacts is preferably surface treated such that the offset compensation member 30 can slide.
본 발명에 의하면 디스크 브레이크를 제동하기 위해 레버(10)에서 트레버스(40)로 제동력이 인가될 때, 레버(10)의 행정에 따라 오프셋 보상 부재(30)가 트래버스(40)의 접촉 면을 따라 상하로 이동하므로 오프셋 문제가 해결된다. 또한 본 발명에서는 오프셋을 보상하는 부재(30)가 하중 전달을 위해 다른 구조와 접촉하는 부분에서 모두 면 접촉하므로 국부 마모가 발생하지 않는다. 또한 본 발명에 의한 오프셋 보상 부재(30)는 비교적 제조가 용이하다. According to the present invention, when a braking force is applied from the lever 10 to the traverse 40 to brake the disc brake, the offset compensation member 30 follows the contact surface of the traverse 40 according to the stroke of the lever 10. Moving up and down solves the offset problem. In addition, in the present invention, since the members 30 for compensating the offset are all face-contacted at the parts in contact with other structures for load transfer, no local wear occurs. In addition, the offset compensation member 30 according to the present invention is relatively easy to manufacture.
이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 하기에 기재될 청구범위의 균등 범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
