Railway track auxiliary shock absorber
The invention provides a railway track auxiliary shock absorber which comprises a shock absorption fastener used for fixing a rail and a shock absorption seat fixedly installed at the bottom of the shock absorption fastener, the rail is subjected to primary shock absorption through the shock absorption fastener, and the vibration frequency conducted to the shock absorption seat is reduced. Then secondary damping is conducted on the track through the damping seat, the damping seat can effectively dissipate track vibration energy through the two oppositely-arranged elastic damping assemblies and the two oppositely-arranged liquid viscous dampers, the vibration amplitude of the track is reduced, the duration time of the track is shortened, and therefore the purpose of damping is achieved, the elasticity of the track is improved, and the service life of the track is prolonged. And noise and vibration of the track are effectively reduced.
本发明提供了一种铁路轨道辅助减震器，包括用于固定铁轨的减震扣件以及固定安装在所述减震扣件底部的减震座，其先通过减震扣件对轨道进行初次减震，并降低传导到减震座上的振动频率。然后通过减震座对轨道进行二次减震，减震座通过两个相对设置的弹性减震组件和两个相对设置的液体粘滞阻尼器能有效地耗散轨道振动的能量，减少轨道的振动幅度和持续时间，从而达到减震的目的，增加了轨道的弹性，有效地减少轨道的噪声和振动。
