The rotary shock absorber suitable for the railway vehicle comprises a shock absorber body, a rotating arm and a connecting rod, a shell is fixed to one side of a connecting mounting plate, a rotating shaft is located in the shell and symmetrically provided with two blades, one end of the rotating shaft is fixed to the center of the connecting mounting plate through a bearing, and the other end of the rotating shaft is fixed to the other side of the connecting mounting plate. The other end of the rotating arm is hinged to one end of the connecting rod, two partition plates are further symmetrically arranged in the shell, and the two partition plates and the two blades divide the interior of the shell into four closed independent cavities with the rotating shaft as the center. And valve plate type valve systems for communicating two adjacent independent cavities are respectively mounted at corresponding positions on the two partition plates. The mounting space is small, mounting is flexible, the length of the rotating arm can be properly adjusted according to the mounting space under the condition that the damping performance is guaranteed, and meanwhile the damping magnitude can be adjusted according to the number of the adjusting valve plates so as to meet the throttling characteristic of a railway vehicle.

    本发明公开了一种适于铁道车辆的旋转减振器,包括减振器本体、转臂和连杆,所述外壳固定在连接安装板的一侧,所述转轴位于外壳内,且对称安装有两片叶片,转轴的一端通过轴承固定在连接安装板的中心,另一端穿出外壳与转臂的一端固定连接,所述转臂的另一端与连杆的一端铰接,所述外壳内还对称设置有两块隔板,两块隔板和两片叶片以转轴为中心将外壳内分隔成四个密闭的独立腔体,两块隔板上的对应位置处分别安装有将相邻两个独立腔体连通的阀片式阀系。本发明安装所需空间小且安装灵活,在保证阻尼性能的情况下,可根据安装空间适当调整转臂长度,同时可根据调节阀片数量来调节阻尼大小,以满足铁道车辆的节流特性。
