3.2 The thickness H of the rubber track can be designed and determined according to the weight and driving torque requirements of the combine harvester. Each width dimension of the track can be designed into several thicknesses of tracks according to the weight range of the applicable machine. 3.3 The pattern of the rubber track should be selected and designed according to the driving and steering performance and walking stability performance requirements of the combine harvester. 3.4 The height h of the rubber track pattern should be selected and designed according to the field operation conditions. 4 Driving form of rubber track
The rubber track can adopt two driving forms: wheel hole or wheel tooth as shown in Figure 3 and Figure 4. 4.1 The hole-type driving wheel is a simple hole-type driving wheel. There is a transmission lug on the transmission part of the rubber track. The wheel hole and the transmission lug are meshed for driving (see Figure 3).
