Tractor Modification With Anti Sinking Half Chain Track for Stable and Reliable Swamp Leveling

Unlike wheeled tractors, tracked tractors are supported on the ground by a coiled circular track. The track contacts the ground, the spikes are inserted into the soil, and the driver is not grounded. Under the action of driving torque, the driving wheel continuously rolls up the track from the rear through the meshing between the teeth on the driving wheel and the joint pin of the track plate. The grounded part of the track exerts a backward force on the ground, and correspondingly gives the track a forward reaction force Pk, which is the driving force that propels the tractor forward. The driving force of a wheeled tractor is directly transmitted to the walking wheels, while a tracked tractor is different. Its driving force Pk is transmitted to the wheel axle of the driving wheel through the tracks wound around the driving wheel, and then transmitted to the driving wheel through the tractor body. When the driving force is sufficient to overcome the rolling resistance and the traction resistance of the carried agricultural tools, the supporting wheels roll forward on the surface of the track, thereby driving the tractor forward. Due to the continuous rolling of the track section by section by the driving wheel, which is then laid on the ground by the guiding wheel, the supporting wheel can continuously roll on the track laid with the track. From this, it can be seen that the operation of a tracked tractor is achieved by the interaction between the track and the ground through the driving torque through the driving wheels, and the driving force is greater than the sum of rolling resistance and traction resistance.
