The invention provides a bogie area full-wrapping skirt bottom plate structure which comprises a side wrapping structure and a bottom wrapping structure, the side wrapping structure is L-shaped on the whole, the bottom wrapping structure is platy, the upper end of the side wrapping structure is fixedly connected with the lower side of a vehicle body, and the horizontal end of the side wrapping structure is fixedly connected with the bottom wrapping structure. The side wrapping structure comprises a side left wrapping structure, a side middle wrapping structure and a side right wrapping structure which are connected in sequence. The aerodynamics performance is effectively improved, the resistance of the whole vehicle is reduced, measures such as local reinforcement and framework pre-burying are adopted, safety and reliability are achieved, the weight is reduced while the structural strength is met, and the requirement for light weight of the vehicle is met; the interface design is innovated, and disassembly and assembly are convenient.
本发明提供一种转向架区域全包覆裙底板结构,包括侧部包覆结构和底部包覆结构,侧部包覆结构整体为L型,底部包覆结构为板状,侧部包覆结构上端与车体下侧固定连接,水平端与底部包覆结构固定连接,侧部包覆结构包括顺次连接的侧部左包覆结构、侧部中包覆结构、侧部右包覆结构。本发明有效改善空气动力学性能,降低整车阻力,采用局部加强及预埋骨架等措施,安全可靠,符合结构强度的同时降低重量,满足车辆轻量化要求;创新接口设计,拆装方便。
