The invention provides a suspension type monorail vehicle body structure which is characterized in that the upper portion of a vehicle body is of an upper underframe combined structure, the lower portion of the vehicle body is of a lower underframe combined structure, side wall assemblies are arranged on the two sides in the length direction of the vehicle body, and end wall assemblies are arranged at the two ends of the vehicle body along the cross section of the vehicle body; the upper underframe combined structure and the lower underframe combined structure are welded to the upper side and the lower side of the side wall assembly respectively, and the periphery of the end wall assembly is welded to the upper underframe combined structure, the side wall assembly and the lower underframe combined structure respectively. The invention is reasonable in design structure and suitable for the suspension type monorail vehicle, and the vehicle section processing performance is reliable; the weight reduction effect is obvious, and the used sectional materials are all of thin-wall structures; modular design is adopted, the number of developed molds is reduced to the maximum extent, and cost is remarkably saved; the structure is stable, the mechanical property is excellent, and an aluminum alloy frame structure is adopted for integral forming.
本发明提供一种悬挂式单轨车车体结构,车体上部为上部底架组合结构,车体下部为下部底架组合结构,延车身长度方向两侧为侧墙组件,延车身横截面车体两端为端墙组件,上部底架组合结构和下部底架组合结构分别焊接于所述侧墙组件的上下两侧,端墙组件四周分别与上部底架组合结构、侧墙组件和下部底架组合结构焊接。本发明设计结构合理,适用于悬挂式单轨车,车辆断面工艺性能可靠;减重效果明显,所用型材均为薄壁结构;采用模块化设计,最大限度减少开发模具的数量,成本节约显著;结构稳定,力学性能优异,采用铝合金框架结构整体成型。
