Patent number: 11466737Abstract: A brake disc for a railway vehicle includes: a disc plate portion that has a sliding portion of a front face; a plurality of radial fins that are provided on the rear face of a disc plate portion, and that have a shape that extends in the radial direction of the disc plate portion; and a circumferential rib that is provided between each pair of adjacent radial fins, and that has a shape that extends in the circumferential direction of the disc plate portion. A flow path for air is formed between the pair of radial fins, and the flow path for air is narrowed by the circumferential rib. On the circumferential rib, a gradual slope for suppressing fluctuations in an airflow that passes between the pair of radial fins is provided from a base part to a top part.Type: GrantFiled: December 6, 2016Date of Patent: October 11, 2022Assignee: NIPPON STEEL CORPORATIONInventors: Nobuo Shiraishi, Yusuke Wakabayashi, Takeshi Kurita, Takanori Kato, Takahiro Fujimoto, Hiroshi Nogami, Atsushi Sakaguchi, Yuki Ichikawa
