The invention provides a lightweight car body end chassis structure which comprises an end plate assembly, two buffer beam assemblies, a car coupler mounting seat, two traction beam assemblies, a sleeper beam seat, an upper cover plate, a lower cover plate assembly and a car end shock absorber seat. According to the invention, reasonable material type selection design, uniform stress distribution design and optimized force flow transmission path design are carried out through a structural lightweight design means under the condition that the structural strength and other system mounting interfaces are not changed, a brand-new vehicle body end chassis structure is invented, and under the condition that the strength standard and the equipment interface are met, the structural strength is greatly improved. Compared with an original structure, the weight is reduced by more than 15%, an existing vehicle body end chassis structure is uneven in stress distribution, complex in structure and large in local stress, and the weight of a single vehicle body is about 540 Kg.

    本发明提供一种轻量化车体端部底架结构,本发明结构包括端板组成、两个缓冲梁组成、车钩安装座、两个牵引梁组成、枕梁座、上盖板、下盖板组成和车端减振器座,本发明通过结构轻量化设计手段在保证结构强度和其他系统安装接口不变的情况下,开展合理的材料选型设计、均匀的应力分布设计和优化的力流传递路径设计,发明一种全新的车体端部底架结构,在符合强度标准和设备接口的情况下,较原结构减重15%以上,既有车体端部底架结构应力分布不均匀,结构复杂,局部存在应力较大的现象,单台重量约540Kg。
