The present invention relates to a railway vehicle with a disc brake on a wheel. More specifically, the present invention relates to a railway vehicle with a disc brake on a wheel, which is able to, when a surface of the disc brake is deformed to be convex by frictional heat generated during a braking process, reduce the deformed part and maintain a contact area with a brake pad to be a certain level or higher and perform a stable braking operation, reduce the overall number of parts, and reduce manufacturing and maintenance cost. To this end, according to the present invention, in the railway vehicle with a disc brake on a wheel, the wheel has installation holes formed to penetrate to the sides at regular intervals. On inner side surfaces of the disc brake located on both sides of the wheel, coupling bump units with fastening holes corresponding to the installation holes are formed to come in contact with a surface of the wheel. The disc brake on the one side has a bolt penetrating the installation holes and the fastening holes. The disc brake on the other side has a nut coupled to an end unit of the bolt.

    본 발명은 제동 디스크가 차륜에 구비된 철도차량에 관한 것으로서, 더욱 상세하게는 제동 작용시 발생하는 마찰열에 의해 제동 디스크의 표면이 볼록하게 변형될 때, 변형되는 범위를 줄여주어 제동 패드와의 접촉면적을 일정 부분 이상 유지하여 안정적인 제동 작용을 수행할 수 있으며, 전체적인 부품수를 줄여주어 제조 및 유지 비용을 절감할 수 있는 제동 디스크가 차륜에 구비된 철도차량에 관한 것이다. 상기한 목적을 달성하기 위한 본 발명은 제동 디스크가 차륜에 구비된 철도차량에 있어서, 상기 차륜에는 일정 간격으로 좌우 관통되는 설치공이 형성되고, 상기 차륜의 양측에 위치하는 상기 제동 디스크의 내측면에는 상기 설치공에 대응되는 체결공이 형성되는 결합돌부가 상기 차륜의 표면에 접하도록 돌출 형성되며, 상기 일측의 제동 디스크에는 상기 설치공과 체결공을 관통하는 볼트가 구비되고, 타측의 제동 디스크에는 상기 볼트의 단부에 결합되는 너트가 구비되는 것을 특징으로 한다.
