The lever 10 also has a support 12a for supporting both ends of the pressure member 6 to prevent the pressure member 6 from being separated from side to side. The hemispherical radius of the pressure member is smaller than the radius of both ends of the support 12a. The channel 13a and the support 12a may be integrally formed to facilitate processing. The channel 13a is preferably formed at a position capable of forming the eccentric shaft of the lever 10. The thrust piece 7 has a groove 14a for supporting the pressure member 6 on the opposite side of the lever 10.
도 5 및 도 6은 제2 실시예에 따른 디스크 브레이크를 나타낸 분해사시도이다. 도 5 및 도 6을 참조하면, 스러스트 피스(7)는 압력 부재(6)의 중앙 부분을 지지할 수 있는 반원 형태의 단면을 가진 홈(14b)을 구비하고, 홈(14)과 압력 부재(6)의 양 끝단의 일부를 지지하여 압력 부재(6)가 좌우로 이탈되는 일을 방지하는 지지부(12b)를 구비한다. 압력 부재의 반구 형상의 반경은 지지부(12b)의 양 끝단의 반경보다 작다. 홈(14b)과 지지부(12b)는 가공을 용이하게 하기 위하여 일체로 형성될 수 있다.5 and 6 are exploded perspective views showing the disc brake according to the second embodiment. 5 and 6, the thrust piece 7 has a groove 14b having a semicircular cross section capable of supporting a central portion of the pressure member 6, and has a groove 14 and a pressure member ( The support part 12b which supports a part of both ends of 6), and prevents the pressure member 6 from leaving left and right is provided. The hemispherical radius of the pressure member is smaller than the radius of both ends of the support 12b. The groove 14b and the support 12b may be integrally formed to facilitate processing.
레버(10)는 스러스트 피스(7)의 반대쪽에서 압력 부재(6)를 지지하는 채널(13b)을 구비한다. 채널(13b)은 레버(10)의 편심축을 형성할 수 있는 위치에 형성될 수 있다. The lever 10 has a channel 13b for supporting the pressure member 6 on the opposite side of the thrust piece 7. The channel 13b may be formed at a position capable of forming the eccentric shaft of the lever 10.
전술한 실시예들에서 압력 부재(6)의 양 끝단은 레버(10) 또는 스러스트 피스(7)에 형성된 지지부(12a, 12b)에 의해 구속되므로, 압력 부재(6)의 좌우 이탈을 방지하기 위한 별도의 리테이너가 필요하지 않다. 또한, 구형 압력 부재 대신에 중앙 부분이 실린더 형태인 압력 부재(6)를 사용함으로 브레이크 실린더(9)를 통해 제공되는 하중이 분산되어 레버(10)의 채널(13a, 13b) 및 스러스트 피스(7)에 형성된 홈(14a, 14b)의 마모를 최소화할 수 있고, 이로부터 차량용 디스크 브레이크의 고장을 최소화할 수 있다. In the above-described embodiments, both ends of the pressure member 6 are constrained by the support portions 12a and 12b formed on the lever 10 or the thrust piece 7, so as to prevent the left and right separation of the pressure member 6. There is no need for a separate retainer. In addition, the load provided through the brake cylinder 9 is distributed by using the pressure member 6 whose central portion is cylindrical in place of the spherical pressure member, so that the channels 13a and 13b and the thrust piece 7 of the lever 10 are distributed. Abrasion of the grooves 14a and 14b formed in the can be minimized, and failure of the disc brake for a vehicle can be minimized.
전술한 실시예에서 압력 부재(6)는 두 개 이상일 수 있다. 이 경우 레버(10)의 채널(13a, 13b) 및 스러스트 피스(7)에 형성된 홈(14a, 14b)도 두 개 이상일 수 있다. In the above-described embodiment, there may be more than two pressure members 6. In this case, two or more grooves 14a and 14b formed in the channels 13a and 13b and the thrust piece 7 of the lever 10 may also be provided.
