The invention provides a front-end chassis structure and a railway vehicle. The front-end chassis structure comprises a pair of edge beams, a pair of front-end chassis structures and a pair of rear-end chassis structures, the buffer beam is arranged in the width direction of the vehicle and connected to the foremost ends of the pair of edge beams. The traction beams are arranged between the pair of side beams in the length direction of the vehicle, and the foremost ends of the pair of traction beams are inserted into the buffer beam; the traction beam is of a fish-belly-shaped structure from front to back. The longitudinal plate beam is connected between the pair of edge beams, the front end of the longitudinal plate beam is inserted into the two transverse sides of the traction beam, and the longitudinal plate beam is suitable for bearing longitudinal force and transverse force of the front-end underframe structure. According to the front-end chassis structure, the traction beam of the fish-belly-shaped structure is arranged to meet the structural limitation requirements that the distance between a passenger room floor surface and a rail surface is small, and the rim diameter is too large; on the basis, the longitudinal plate beams are additionally arranged to improve the longitudinal compression load bearing capacity of the front-end underframe structure, and the requirement for maximizing the longitudinal compression load bearing capacity and the requirement for bearing vertical and transverse loads are met on the basis that structural limitation is met.
本发明提供一种前端底架结构及轨道车辆,包括:一对边梁成间隔设置,且均沿车长方向设置;缓冲梁沿车宽方向设置,且连接于一对边梁的最前端;牵引梁沿车长方向设置于一对边梁之间,一对牵引梁的最前端均插接于缓冲梁;牵引梁自前向后构造成鱼腹型结构;纵向板梁连接于一对边梁之间,纵向板梁的前端插接于牵引梁的横向两侧,纵向板梁适于承载前端底架结构的纵向力和横向力。该前端底架结构通过设置鱼腹型结构的牵引梁以适应客室地板面距离轨道面较低,轮缘直径过大等结构限制要求;在此基础上,增设纵向板梁提高前端底架结构的纵向压缩载荷承载能力,实现在符合结构限制基础上,满足纵向压缩载荷承载能力最大化的要求、垂向及横向载荷承载要求。
