The invention discloses a subway track damping device, and belongs to the technical field of underground track traffic. The device comprises a base, a track support plate and tracks parallelly arranged on the track support plate at intervals, the base and the track support plate are supported by elastic support blocks, a plurality of groups of damping devices are further arranged between the base and the track support plate, and each group of damping devices are symmetrically distributed on the two sides of the tracks; a rotating shaft is fixedly connected to a rotating core body, and the rotating core body is in friction fit with the inner wall of the outer shell; and a force application sleeve axially moves, a sliding rod drives the rotating shaft and the rotating core body to rotate, and damping and noise reduction are achieved through friction energy dissipation between the rotating core body and the outer shell. According to the device, the running track of the metro is damped, so that noise in the running process of the metro is reduced, and a more comfortable riding environment is brought to passengers.
本发明公开了一种地铁轨道减震装置，属于地下轨道交通技术领域，包括底座、轨道支撑板、平行间隔设置在所述轨道支撑板上的铁轨，所述底座与轨道支撑板之间通过弹性支撑块支撑，所述底座与轨道支撑板之间还设置有若干组减震装置，每一组减震装置对称分布在所述铁轨的两侧；所述转动轴固定连接至转动芯体，所述转动芯体与所述外壳体的内壁之间摩擦配合；所述施力套筒轴向移动，所述滑杆带动转动轴和转动芯体旋转，通过所述转动芯体和外壳体之间摩擦耗能实现减震降噪。本发明装置通过对地铁的行驶轨道进行减震，以降低地铁在运行过程中的噪音，给乘客带来更舒适的乘车环境。
