    • 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.
    • 铁路车轮包括:包括板部分(13)的轮(10); 以及包括其前面(2a)侧为滑动面的圆板部(2)的制动盘(1)和径向突出于圆周面(2b)的背面(2b)的多个翅片部(3) 板部分(2),其中两个制动盘(1)将车轮(10)的板部分(13)插入其每个滑动表面面向外,并且紧固在滑动表面内的区域中。 关于沿周向与制动盘(1)和车轮(10)之间形成的空间的区域的区域,在由外周面形成的区域中存在截面积最小的最小截面部 (2)的圆周面(2c)和边缘部(12)的内周面(2c)之间,圆板部(2)的外周面(2c)与内周面(12b) )在从最小部分部分延伸到外侧的区域中。 铁路车轮包括具有简单形状和优异生产率的制动盘,并且可以有效地降低高速行驶期间的空气动力学声音。
