The invention provides an ISD air spring, a bogie suspension system and a locomotive. The ISD air spring comprises an upper cover assembly, rubber-metal pad assemblies, air bags and inerters; the rubber-metal pad assemblies are arranged below the upper cover assembly at intervals; the air bags are arranged between the upper cover assembly and the rubber-metal pad assemblies to form air cavities; the inerters are arranged in the air cavities, one free end point of each inerter is connected with the corresponding upper cover assembly, and the other free end points of the inerters are connected with the rubber-metal pad assemblies; and the inerters are kept horizontal in the transverse direction. According to the ISD air spring, the inerters are arranged in the air cavities in the air spring, so that the transverse impact load buffering capacity of the air spring is improved, the technical problem that because the air spring for a railway vehicle bears the transverse impact load, the transverse stability and comfort of the vehicle are low is solved, and meanwhile transverse low-frequency shaking of the vehicle is prevented or reduced.

    本发明提出一种I SD空气弹簧及转向架悬挂系统、机车。所述I SD空气弹簧包括:上盖组成;橡胶堆组成,所述橡胶堆组成间隔设置在所述上盖组成的下方;气囊,所述气囊设置在所述上盖组成与所述橡胶堆组成之间,形成气腔;惯容器,所述惯容器设置在所述气腔内,其一个自由端点与所述上盖组成连接,另一个自由端点与所述橡胶堆组成连接;所述惯容器在横向方向上保持水平。本发明通过在空气弹簧内部气腔内设置惯容器,提高了空气弹簧缓冲横向冲击载荷的能力,解决轨道车辆用空气弹簧承受横向冲击载荷导致车辆横向稳定性和舒适性低的技术问题,同时防止或降低车辆横向的低频晃动。
