The invention discloses a railway vehicle body chassis boundary beam and a connecting structure thereof, the railway vehicle body chassis boundary beam comprises a straight boundary beam and a bevel edge beam used for being connected with a cab, the straight boundary beam and the bevel edge beam are connected in an inserting mode, the inserting depth of the straight boundary beam and the bevel edge beam is 200-600 mm, and the inserting angle is 0-15 degrees. The connection structure is reasonable in design, the straight edge beam and bevel edge beam connection structure can form more connection welding seams consistent with the main stress direction of a vehicle body, the connection structure is high in strength, transmission of longitudinal force of the vehicle body is better facilitated, and the situation that a connection interface of the bevel edge beam and the straight edge beam suddenly changes to easily generate gravity concentration is prevented; smooth transition of stress is achieved through a connecting piece on an interface in an abrupt change mode, by adjusting the insertion angle, the vehicle body structure can be matched with a long and thin cab structure, the vehicle body structure has more excellent aerodynamic performance and attractiveness, and the vehicle body structure is more suitable for urban vehicles and the like with the high speed grade and can also be matched with a short cab structure. And the train body structure is more suitable for subways and light rail trains with lower speed grades.

    本发明公开了一种轨道车辆车体底架边梁及其连接结构,包括直边梁和用于连接司机室的斜边梁,所述直边梁和斜边梁之间插接,所述直边梁和斜边梁的插接深度为200mm—600mm,且插接角度为0°‑15°。本发明设计合理,直边梁和斜边梁连接结构会形成更多的与车体主应力方向一致的连接焊缝,连接结构强度高更有利于车体纵向力的传递,防止斜边梁与直边梁连接的界面突变出容易产生引力集中,在界面突变出用连接件实现应力的平滑过渡,通过调整插入角度,可以与较为细长的司机室结构搭配,其车体结构具有更优秀的空气动力学性能和美观,更适用于速度等级较高的市域车等,也可以与较为短促的司机室结构搭配,其车体结构更适合速度等级较低的地铁和轻轨列车。
