The invention relates to the technical field of railway vehicles, and provides a longitudinal damping device, a bogie and a railway vehicle. The longitudinal vibration damping device comprises a first mounting seat, a second mounting seat, a longitudinal vibration damper and a traction rod. The first mounting seat is suitable for being mounted on a bogie of a railway vehicle. The second mounting base is suitable for being mounted on a vehicle body of the railway vehicle and provided with a first connecting end and a second connecting end in the height direction in a spaced mode. One end of the longitudinal shock absorber is connected with the first mounting seat, and the other end of the longitudinal shock absorber is connected with the first connecting end. One end of the traction rod is connected with the second connecting end, and the other end of the traction rod is suitable for being connected to the bogie. Wherein the longitudinal shock absorber and the traction rod are arranged in parallel at an interval. The nod motion between the vehicle body and the bogie can be effectively restrained, and therefore the comfort level and safety of vehicle operation are improved.

    本发明涉及轨道车辆技术领域,提供一种纵向减振装置、转向架及轨道车辆。该纵向减振装置包括第一安装座、第二安装座、纵向减振器和牵引拉杆。第一安装座适于安装于轨道车辆的转向架。第二安装座适于安装于轨道车辆的车体,第二安装座沿高度方向间隔构造有第一连接端和第二连接端。纵向减振器的一端与第一安装座相连,纵向减振器的另一端与第一连接端相连。牵引拉杆的一端与第二连接端相连,牵引拉杆的另一端适于连接于转向架。其中,纵向减振器与牵引拉杆间隔且平行布置。能够有效抑制车体与转向架之间的点头运动,从而提高车辆运行的舒适度和安全性。
