The invention relates to the technical field of trains, and discloses a double-buffering train floating floor shock absorber which comprises a buffering box, an air cylinder is fixed to the bottom of the buffering box and penetrates through the bottom of the buffering box, a fourth piston block is slidably connected into the air cylinder, and a liquid storage box is fixed to the bottom of the buffering box. And a cooling mechanism is arranged on the outer side of the liquid storage tank. According to the double-buffering train floating floor shock absorber, in the running process of a train, a buffering spring stretches out and draws back, a piston plate vertically slides back and forth in a buffering box, when the piston plate moves downwards, a first through hole is automatically opened, and when the piston plate moves upwards, a second through hole is automatically opened; the upward moving distance of the piston plate is smaller than the downward moving distance each time, the buffering and damping effect is conveniently achieved, gas is stored in the air cylinder, the fourth piston block reciprocates in the air cylinder, damping force is generated through gas compression and release, vibration is attenuated, and the double buffering effect is conveniently achieved.

    本发明涉及列车相关技术领域,本发明公开了双重缓冲的列车浮筑地板减振器,包括缓冲箱,所述缓冲箱的底部固定有气缸,所述气缸贯穿缓冲箱的底部,所述气缸内滑动连接有第四活塞块,所述缓冲箱的底部固定有储液箱,所述储液箱的外侧设置有冷却机构。该双重缓冲的列车浮筑地板减振器,列车在行驶的过程中,缓冲弹簧伸缩,活塞板在缓冲箱内上下来回滑动,活塞板下移时,第一通孔自动打开,活塞板上移时,第二通孔自动打开,由于第二通孔始终小于第一通孔,活塞板每次上移距离小于下移距离,方便实现缓冲减震的效果,气缸内储存有气体,第四活塞块在气缸内往复运动,气体压缩与释放产生阻尼力,使振动衰减,方便实现双重缓冲的效果。
