The four wheels in "four wheels and one belt" refer to the segment, idler,
Track Roller, and carrier rollers, and the "one belt" refers to the tracks shoe assy. They are directly related to the working performance and walking performance of the excavator, and their weight and manufacturing cost account for a quarter of the manufacturing cost of the excavator or bulldozer.
The track shoe assy, which tend to mesh with the driving wheels, and the track plate itself becomes the rolling track of wheels such as rollers. The track manufacturing material is 50MN or 45SIMN, and its hardness reaches HRC55-58.
The function of the track rollers is to transfer the weight of the excavator to the ground. When the excavator is traveling on uneven roads, the rollers will be impacted by the ground. Therefore, the load on the rollers is large, the working conditions are harsh, and they are often exposed to dust. , sometimes soaked in muddy water, so good sealing is required. Manufacturing materials,mostly is 35MN and 50MN. The wheel surface is quenched to a hardness of HRC48 or 57 to obtain good wear resistance.
The idlers are used to guide the crawler track to rotate correctly to prevent it from wandering and derailing. The function of the carrier roller is to hold the track upwards so that the track has a certain degree of tension.
