Rail transit damping mechanism

The invention belongs to the technical field of rail transit, and particularly relates to a rail transit damping mechanism. Comprising a sleeper rail and a steel rail, the sleeper rail is sequentially provided with an insulating buffer cushion plate, an iron cushion plate lower heightening cushion plate, an iron cushion plate, an under-rail heightening cushion plate and an under-rail cushion plate from bottom to top, the top of the under-rail cushion plate is attached to the bottom of the steel rail, and two anchor bolts are symmetrically connected to the two sides of the sleeper rail in a threaded mode; the top end of the anchor bolt extends to the position above the iron base plate. Vibration energy on the steel rail can be evenly dispersed through the buffering blocks evenly distributed on the under-rail base plate, the vibration energy is converted into heat energy generated by friction between the damping blocks and the wedge-shaped blocks, the effect of reducing vibration is further ...
