The invention discloses a coating structure, a bogie assembly and a railway vehicle, the coating structure comprises a bottom plate, the bottom plate is used for coating the bottom of a bogie, the bottom plate is provided with an opening part, and the opening part is used for avoiding wheels of the railway vehicle. The wrapping structure can wrap the bottom of the bogie, when flowing through the bottom of the bogie, airflow does not enter complex components in the bogie to flow, but directly flows away through the bottom face of the bottom plate, and therefore aerodynamic resistance borne by the bogie area can be reduced. Besides, the bottom plate is provided with the opening part for avoiding the wheels, the wrapping structure and the framework of the bogie are fixed, and the relative movement between the wrapping structure and the wheels is small, so that the opening part is used as the position for avoiding the wheels, the occupied space is small, the resistance influence generated when airflow enters the bogie from the opening part can be reduced, and the effect of reducing the running resistance of the wrapping structure is not influenced.
本申请公开一种包覆结构、转向架总成以及轨道车辆,所述包覆结构包括底板,所述底板用于包覆所述转向架的底部,所述底板开设有开口部,所述开口部用于避让轨道车辆的车轮。本申请中的包覆结构可以包覆转向架的底部,气流在流经转向架的底部时,不会进入转向架内部复杂的部件中流动,而是直接经底板的底面流走,从而可以降低转向架区域所受的气动阻力。此外,在底板设置避让车轮的开口部,由于包覆结构和转向架的构架固定,与车轮相对运动较小,因此开口部作为避让车轮的位置,占据空间较小,可减少气流从开口部进入转向架内而产生的阻力影响,不影响包覆结构降低运行阻力的效果。
