摘要： A railroad car wheel having an annular hub for connection to an axle and defining an inner radial surface adapted for disposition in facing relating to the inner surface of a wheel on the opposite end of the axle and an outboard radial surface facing outwardly of the wheel, an annular tread defining rim portion disposed generally concentrically of the hub and defining an inner radial surface adapted for disposition in facing relation to the inner surface of a wheel on the opposite end of the axle and an outboard radial surface facing outwardly of the wheel, the rim portion being displaced axially outwardly with respect to the hub and including an outer, generally cylindrical rail engaging surface provided with radially extending flange adjacent the inner radial surface, and an integral annular plate portion connecting the rim and hub, the plate having a relatively thin cross section and being generally frusto-conical defining inboard and outboard conical surfaces, the plate joining the hub adjacent the inner radial surface with the inboard conical surface of the plate merging into the inner radial surface of the hub, the plate joining the rim with at least one of the inboard and outboard conical surfaces merging respectively with one of the inner radial outboard radial surfaces of the rim.
摘要翻译：一种铁路车轮，其具有用于连接到车轴的环形轮毂，并且限定内径向表面，所述内径向表面适于相对于所述轴的相对端上的车轮的内表面以及面向车轮外侧的外侧径向表面配置，环形胎面限定轮缘部分大体上同轴地设置在轮毂上，并且限定内径向表面，该内径向表面适于以相对于轮轴的相对端上的车轮的内表面相对配置，以及面向车轮外侧的外侧径向表面。轮辋部分相对于轮毂轴向向外移位，并且包括外部大致圆柱形的轨道接合表面，其设置有邻近内部径向表面的径向延伸的凸缘，以及连接轮辋和轮毂的整体环形板部分，该板具有相对较薄的横截面并且通常为截头圆锥形，限定内侧和外侧锥形表面，该板接合靠近内径向表面的毂与内板的圆锥形表面汇合成轮毂的内径向表面，连接边缘的板与内侧和外侧锥形表面中的至少一个分别与内径向外侧径向轮辋表面
