The invention relates to the technical field of railway vehicles, in particular to a railway vehicle secondary inerter suspension device which comprises a base, a suspension upper cover arranged on the end face of the base and an air bag arranged on the end face of the suspension upper cover. The damping assembly comprises a first shell, a first valve arranged in the first shell and a lead screw arranged in the first shell; the auxiliary assembly comprises a first fixing frame arranged on the outer wall of the lead screw, a first sliding column arranged in the first fixing frame and a sliding frame arranged on the outer wall of the first fixing frame. A device with an oil pressure buffering function based on the inerter principle is additionally arranged on the air spring, and rotation of the lead screw is slowed down through wind resistance, so that the shaking influence of fluctuation in different directions on a train in the running process of the train is reduced, and the stability of the train in the running process is optimized.

    本发明涉及轨道车辆技术领域,特别是一种轨道车辆二系惯容悬挂装置,包括有组件,包括有底座、设于所述底座端面的悬挂上盖和设于所述悬挂上盖端面的气囊;以及,阻尼组件,包括有第一外壳、设于所述第一外壳内部的第一阀门和设于所述第一外壳内部的丝杆;以及,辅助组件,包括有设于所述丝杆外壁的第一固定框、设于所述第一固定框内部的第一滑柱和设于所述第一固定框外壁的滑框;本发明通过在空气弹簧上加入惯容原理的油压缓冲功能的装置,再利用风阻起到丝杆回转的减缓,以此去减少列车在运行过程中不同方位波动对列车产生的抖动影响,以此去优化列车在运行过程中的平稳性。
