Disclosed is a connecting structure for an underframe edge beam and a side wall of a straddle-type monorail vehicle body. The connecting structure for the underframe edge beam and the side wall of thestraddle-type monorail vehicle body is capable of improving the structural strength of an underframe structure, simplifying the manufacturing process, and greatly reducing the arc welding quantity. The whole structure is formed by combining and welding hollow double-wall large aluminum alloy extrusion profiles, and the structure is designed to be lightweight. The longitudinal full-length arrangement of an underframe edge beam profile ensures that the strength and rigidity of the vehicle body satisfy the requirements under the action of longitudinal, vertical, torsional and other loads. An insertion connector is designed at the connecting position of the underframe edge beam profile and the side wall so as to simplify the connecting form of the side wall and an underframe, improve the assembly precision of the side wall and the underframe, reduce the assembly difficulty, reduce the amount of welding seams at the connecting position of the side wall and the underframe, and improve the overall quality and precision. A lap joint connector is designed at the position where the underframe edge beam profile is connected to an aluminum bottom plate in the horizontal direction, and the structure is convenient to be assembled and welded to the aluminum bottom plate. The overall width of the underframe aluminum structure can be adjusted during underframe final assembly, and the requirement for manufacturing precision is satisfied.

    一种跨座式单轨车体底架边梁及侧墙连接结构,本发明提高了底架结构的结构强度,简化了制造工艺,大大减少了弧焊焊接量。整体结构采用中空双壁大型铝合金挤压型材组合焊接而成,并结构进行了轻量化设计,底架边梁型材纵向通长布置保证了车体在纵向、垂向、扭转等载荷作用下,强度、刚度满足要求。该底架边梁型材与侧墙连接处设计插接接口,简化了侧墙与底架处连接形式,提高了侧墙与底架装配精度,减小了装配难度,减少了侧墙与底架连接处焊缝数量,对整体质量、精度有所提高,水平方向底架边梁型材与铝地板连接处设计搭接接口,此结构便于与铝底板装配焊接,在底架总装时可调整底架铝结构整体宽度尺寸,保证了制造精度的要求。
