Overseas Farmers Are All Competing! Large Harvester Tractor Modified With Rubber Half Track, Harvesting and Transportation Fully Completed

Crawler walking mechanisms are widely used in field work vehicles such as construction machinery and tractors. The walking conditions are harsh, requiring the walking mechanism to have sufficient strength and stiffness, as well as good walking and turning capabilities. The tracks are in contact with the ground, while the drive wheels are not in contact with the ground. When the motor drives the driving wheel to rotate, the driving wheel continuously rolls up the track from the rear through the meshing between the teeth on the driving wheel and the track chain under the action of the driving torque of the reducer. The grounded part of the track exerts a backward force on the ground, while the ground correspondingly exerts a forward reaction force on the track, which is the driving force that propels the machine forward. When the driving force is sufficient to overcome the walking resistance, the supporting wheels roll forward on the surface of the track, causing the machine to move forward. The front and rear tracks of the whole machine's track walking mechanism can turn independently, making its turning radius smaller
