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.

The main function is to cooperate with the tensioning device to achieve elastic tensioning of the track. The function of the tensioning device is to achieve the tensioning effect by pushing the guide wheel through the spring. Therefore, compression and tension springs can be selected.

The front and rear positions of the guide wheel are determined by the position of the drive wheel and are usually arranged at the front. The guide wheel is used to guide the track to rotate correctly, which can prevent deviation and deviation. The height of the guide wheel above the ground should be conducive to reducing it.

The support wheel is one of the four wheels in the chassis of tracked construction machinery. Its main function is to support the weight of excavators and bulldozers, allowing the tracks to move forward along the wheels. The number and arrangement of supporting wheels should be conducive to evenly distributing the ground pressure of the track. Agricultural walking mechanisms work mostly in mountainous or hilly areas, where the road surface is mostly dirt. The track device requires a small average ground pressure, and the pressure on the supporting wheels needs to be evenly distributed
