The invention discloses a railway wheel, and relates to the technical field of wheels, the railway wheel comprises a wheel main body, the wheel main body comprises a hub body, a wheel disk body and a rim body, the outer side of the hub body is connected with the inner side of the wheel disk body, and the outer side of the wheel disk body is connected with the inner side of the rim body; the radial plate body comprises a radial plate first section, a radial plate second section, a radial plate third section, a radial plate fourth section and a radial plate fifth section which are sequentially connected, the end, away from the radial plate second section, of the radial plate first section is connected with the hub body, and the end, away from the radial plate fourth section, of the radial plate fifth section is connected with the rim body; the first radial plate section, the second radial plate section, the fourth radial plate section and the fifth radial plate section are all of bent structures, and the third radial plate section is parallel to the radial direction of the wheel of the wheel body. Under the condition of high braking heat-mechanical stress, the axial deformation of the rim body is small, and the anti-fatigue performance of the wheel body is high.
本发明公开了一种铁路车轮,涉及车轮技术领域,包括车轮主体,车轮主体包括轮毂本体、辐板本体和轮辋本体,轮毂本体的外侧与辐板本体的内侧连接,辐板本体的外侧与轮辋本体的内侧连接,辐板本体包括依次连接的辐板第一区段、辐板第二区段、辐板第三区段、辐板第四区段和辐板第五区段,辐板第一区段远离辐板第二区段的一端与轮毂本体连接,辐板第五区段远离辐板第四区段的一端与轮辋本体相连接,辐板第一区段、辐板第二区段、辐板第四区段和辐板第五区段均为弯曲结构,辐板第三区段与车轮主体的车轮径向方向平行。本发明在较高的制动热‑机械应力情况下,轮辋本体轴向形变小,车轮主体抗疲劳性能高。
