company news about Tractor driving principle

Tractor can drive is by the power of the internal combustion engine by the transmission system, so that the drive wheel to obtain the drive torque Mk, to obtain the drive torque of the drive wheel and then through the tire tread and tire surface to the ground small, backward horizontal force (tangential force), and the ground to the drive force of equal size, the direction of the opposite of the horizontal meal force Pk, this Pk meal force is to promote the tractor forward driving force (also known as feed for propulsion). When the driving force Pk enough to overcome the front and rear wheels forward rolling resistance and traction resistance with farm equipment, the tractor will move forward. If the driving wheel support off the ground, that is, the driving force Pk equal to zero, the driving wheel can only idle in place, the tractor can not travel; if the rolling resistance and traction resistance and greater than the driving force Pk, the tractor can not travel. This can be seen wheeled tractor is driven by the driving torque drive wheel and the interaction between the ground and achieve, and the driving force to be greater than the rolling resistance and traction resistance and.
