The invention discloses a rail transit anti-side-rolling device after-breakage anti-falling device which comprises two anti-falling units of the same structure, the two anti-falling units are arranged on the inner sides of supporting seat assemblies in the symmetrically-arranged anti-side-rolling device correspondingly, and each anti-falling unit is fixedly connected with a framework of a rail vehicle. The anti-falling unit is provided with a fixing hole which allows the torsion bar to penetrate through and does not affect work of the torsion bar. Even if the torsion bar is fractured at the two ends of the supporting seat assembly in the anti-side-rolling device in the vehicle service process, the fractured torsion bar part can be supported by the anti-falling device and cannot fall on a rail.

    本申请公开了一种轨道交通用抗侧滚装置断后防掉落装置,包括两组结构相同的防掉落单元,两组防掉落单元分别设置在对称布置的抗侧滚装置中的支撑座组件的内侧,每组所述防掉落单元与轨道车辆的构架固定连接,防掉落单元上设有供扭杆穿过且不影响扭杆工作的固定孔。即使扭杆在车辆服役过程中在抗侧滚装置中支撑座组件的两端均发生断裂,断裂后的扭杆部分可由本发明的防掉落装置支撑,不会掉落于轨道上。
