The invention discloses a straddle type monorail vehicle body chassis structure which comprises a chassis framework and a floor arranged at the upper end of the chassis framework, and the chassis framework is formed by combining and welding hollow large aluminum alloy extruded profiles. The chassis framework comprises a front end beam, a cab edge beam, a front inner end beam, a cab end sleeper beam assembly, a chassis edge beam, a two-position end sleeper beam assembly and a rear end beam, and the front end beam, the cab edge beam, the front inner end beam, the cab end sleeper beam assembly, the chassis edge beam, the two-position end sleeper beam assembly and the rear end beam are fixed through welding. The invention has the advantages of simple structure, reasonable design, small welding amount, light weight design, easy realization of modularization, convenient production and processing technology, simple field operation, easy realization of bogie and tire area avoidance, simple structure, high space utilization rate, and realization of low floor structure design. And the structural strength and rigidity of the vehicle body chassis are improved.

    本发明公开了一种跨座式单轨车体底架结构,包括底架骨架和设置在底架骨架上端的地板,所述底架骨架采用中空大型铝合金挤压型材组合焊接而成,所述底架骨架包括有前端梁、司机室边梁、前内端梁、司机室端枕梁组件、底架边梁、二位端枕梁组件和后端梁,所述前端梁、司机室边梁、前内端梁、司机室端枕梁组件、底架边梁、二位端枕梁组件和后端梁之间通过焊接固定。本发明结构简单,设计合理,采用中空大型铝合金挤压型材组合焊接而成,焊接量少,轻量化设计,易于实现模块化,生产加工工艺方便,现场操作简单,易于实现转向架及轮胎区域避让,结构简单空间利用率高,可实现低地板结构设计,提高了车体底架的结构强度和刚度。
