Disclosed herein is a two-piece rail wheel assembly that allows for tire replacement without the need to disintegrate the rail car or remove components directly attached to the axle. In various embodiments, the rail wheel assembly includes a center hub attached to an axle of a rail car and a tire configured to engage a rail. The central hub and the tire can be connected together by bolts through a stepped (or recessed) interface. When used in a built-in bearing configuration, such a rail wheel assembly does not require the use of a press, does not require detachment of a bogie assembly from a rail car, or does not require detachment of a wheelset from a bogie. When used in an external bearing configuration, such a rail wheel assembly does not require the use of a press or the removal of any other component of the wheelset from the axle.

    本文公开了一种允许更换轮胎而不需要分解轨道车或移除直接附接至车轴的部件的两件式轨道车轮组件。在多种实施例中,所述轨道车轮组件包括附接至轨道车的车轴的中心轮毂和被配置成与轨道接合的轮胎。所述中心轮毂和所述轮胎可以通过台阶式(或凹陷的)接口用螺栓连接在一起。在用于内置轴承配置时,这种轨道车轮组件不需要使用压力机,不需要从轨道车分离转向架组件,或者不需要从转向架分离轮组。在用于外置轴承配置时,这种轨道车轮组件不需要使用压力机或从车轴上移除轮组的任何其它部件。
