The rollers transfer the weight of the bulldozer to the ground and prevent the bulldozer from rolling along the track and slipping on the track. When the bulldozer is driving on uneven roads, the rollers can often withstand the impact of the ground, which puts heavy loads on the rollers. Depending on the structure, the role can be divided into a side role and a two-sided role. The drive wheel of the high-performance bulldozer adopts the alternating arrangement of single-sided and double-sided carrier wheels, the single-sided carrier wheel and a double-sided carrier wheel forming a group. The long compensation arm connected to the profile frame is shown in Figure 3.5. Each group of road bikes can easily swing around the pivot point of the arm. short balancing and can swing with greater amplitude around the hinge point of the long balance arm. The frame can better absorb the vibration shock from the floor.
