Problems solved by technology
[0002] In rail transit, during the high-speed contact between the wheel and the track, it will inevitably generate a large amount of impact energy and make a huge noise. In order to reduce the noise during the running of the vehicle, rubber rings are often lined under the track at present, but in China The load of the railway is heavy, the actual service life of the rubber shock absorbing ring is short, and it is troublesome to replace it. After a period of use, the shock absorbing effect becomes weaker and the noise increases

The invention discloses a track shock absorber which is characterized by comprising a track, a sleeper and a railway ballast, wherein a damping device is arranged between the sleeper and the railway ballast; the damping device comprises damping plates and two dampers, wherein the damping plates are arranged in the force bearing positions of two sides of the sleeper, and the two dampers are installed in the damping plates and are symmetrically arranged at the two sides of the sleeper; and each damper is provided with a compression guide rod, a damping chamber and a compression compartment arranged below the damping chamber, wherein the damping chamber is internally filled with air, a compression plate is arranged above the damping chamber, the compression plate is connected to the compression guide rod, a leak-proof baffle plate is arranged between the damping chamber and the compression compartment, and a fluorine rubber sealing ring is arranged on a contact surface between the leak-proof baffle plate and a shock absorber wall. The track shock absorber can improve the damping performance.
Description
technical field [0001] The invention relates to the technical field of transportation, in particular to a track shock absorber for railways. Background technique [0002] In rail transit, during the high-speed contact between the wheel and the track, it will inevitably generate a large amount of impact energy and make a huge noise. In order to reduce the noise during the running of the vehicle, rubber rings are often lined under the track at present, but in China The railway load is heavy, the actual service life of the rubber shock absorbing ring is short, and it is troublesome to replace it. After a period of use, the shock absorbing effect becomes weaker and weaker, and the noise emitted increases. Contents of the invention [0003] The present invention aims to provide a rail shock absorber to improve better shock absorption effect, so as to solve the above problems. [0004] To achieve the above object, the technical scheme of the present invention is as follows: ...
