[0002] A train refers to a vehicle that runs on railway tracks, usually composed of multiple carriages. It is one of the important modern means of transportation for humans. When a traditional coal-fired train is working, a turbo train supercharger is needed to increase the air intake of the combustion chamber or engine so that the fuel can be fully burned.

[0003] Existing train superchargers are generally installed with rigid connection, and the train supercharger is directly fixed on the base by bolts. However, when the train moves, the train supercharger will cause high-frequency vibration. The vibration can easily cause the train supercharger parts to loosen and cause abnormal noise, which is inconvenient to use. Therefore, we propose a train supercharger with a shock absorbing mechanism to solve the problem. Utility Model Content
