철도 차륜은, 판부(13)를 구비한 차륜(10)과, 표면(2a)측을 슬라이딩면으로 하는 원판부(2), 및 원판부(2)의 이면(2b)에 돌출 설치된 복수의 핀부(3)를 구비한 브레이크 디스크(1)를 구비하고, 2장의 브레이크 디스크(1)가 개개의 슬라이딩면을 바깥쪽을 향하게 한 상태로 차륜(10)의 판부(13)를 사이에 끼워 넣어, 상기 슬라이딩면의 영역 내에서 체결되어 이루어진다. 브레이크 디스크(1)와 차륜(10)의 사이에 형성된 공간을 원주방향을 따라 횡단하는 단면의 면적에 대해, 이 단면적이 최소가 되는 최소 단면부가, 원판부(2)의 외주면(2c)과 림부(12)의 내주면(12b)으로 형성되는 영역에 존재하고, 원판부(2)의 외주면(2c)은, 최소 단면부를 기점으로 한 외측의 영역에서, 림부(12)의 내주면(12b)을 따른다. 이 철도 차륜은, 간소한 형상으로 생산성이 우수한 브레이크 디스크를 구비하고, 고속 주행 중의 공력음을 유효하게 저감하는 것이 가능하다.

    A railway wheel includes: a wheel (10) including a plate portion (13); and a brake disc (1) including a circular plate portion (2) whose front face (2a) side is a sliding surface, and a plurality of fin portions (3) which are radially projected on a back face (2b) of a circular plate portion (2), wherein two of the brake discs (1) interpose the plate portion (13) of the wheel (10) with each of sliding surfaces thereof facing outwardly, and are fastened in a region within the sliding surface. Regarding an area of a section crossing a space formed between the brake disc (1) and the wheel (10) along a circumferential direction, a minimum section portion in which the sectional area is minimum is present in a region formed by an outer peripheral surface (2c) of the circular plate portion (2) and an inner peripheral surface (2c) of the rim portion (12), and the outer peripheral surface (2c) of the circular plate portion (2) follows the inner peripheral surface (12b) of the rim portion (12) in a region extending to the outer side from the minimum section portion. The railway wheel includes a brake disc which has a simple shape and an excellent productivity, and can effectively reduce aerodynamic sound during high speed travelling.
