The main function of the tensioning device is to achieve the tensioning function of the track and prevent belt dropping.

The buffer spring of the tensioning device has a certain preloading amount, which generates a pre tensioning force in the track. Its function is to not affect the meshing between the track pin and the driving gear teeth due to slight external forces when moving forward, and to generate sufficient traction force to ensure the normal meshing between the track pin and the driving gear teeth.

The tension spring, due to the recoil effect of the device, presses against the guide wheel on the right side to maintain a certain tension state during operation, thereby guiding the track tension guide wheel
