About

Crawler tractors, also known as "track tractors" or "track tractors", are a type of tractor.

Walking device by the guide wheel, follow the wheel, roller, wheel and track form. During operation, the driving wheel is wound around the track to circulate, and the track rollers roll forward or backward on the track of the track.


Has the advantages of small pressure per unit area of the soil and good adhesion to the soil (not easy to slip), etc., in the wet and soft soils have better performance, traction efficiency is high.

Crawler tractors and wheeled tractors, it is supported by a winding loop crawler on the ground. Track contact with the ground, track into the soil, the driver is not grounded. The driving wheel, under the action of driving torque, continuously and continuously catches the track from the rear by the engagement between the teeth on the driving wheel and the shoe pins of the track shoe. Grounding that part of the track to the ground a backward force, but also need to be a corresponding response to the track before the reaction force Pk, this Pk reaction is to promote the driving force tractor forward. The driving force of the wheeled tractor is directly transmitted to the running wheels, whereas the crawler tractor is different in that the driving force Pk is transmitted to the wheel axle of the driving wheel through the track wound on the driving wheel, and then transmitted by the axle through the body of the tractor To the drive wheel. When the driving force is enough to overcome the rolling resistance and traction resistance of the farm implements, the roller wheels roll forward on the upper surface of the crawler track to make the tractor move forward. Since the drive wheels continuously feed the track sections one by one forward and over the guide wheels to the ground, the track rollers can be continuously rolled on tracked tracks. It can be seen from this that the crawler tractor is driven by the driving torque through the driving wheel to make the interaction between the crawler and the ground, and the driving force is greater than the sum of the rolling resistance and the traction resistance.
