Agricultural tractors, a class of tractors, i.e. tractors with running gear on wheels. The high-horsepower agricultural tractor has good traction performance and is suitable for high-speed operation with wide range farm tools. The tractor of agricultural equipment belongs to this category of tractor equipment, so how does it work, or how does it work?
The tractor can drive by relying on the power of the internal combustion engine through the transmission system, so that the driving wheel obtains the driving torque Mk, and the driving wheel that obtains the driving torque then gives the ground a small and backward horizontal force (tangential force) through the tire pattern and the tire surface, and the ground is equal in the driving force and the horizontal reaction force Pk in the opposite direction, and the Pk reaction force is the driving force that pushes the tractor forward (also known as the feeding propulsion force). When the driving force Pk is sufficient to overcome the forward rolling resistance of the front and rear wheels and the traction resistance of the carrying farm implements, the tractor moves forward. If the driving wheel is broken off the ground, that is, the driving force Pk is equal to zero, the driving wheel can only idle in place, and the tractor can not drive; If the sum of rolling resistance and traction resistance is greater than the driving force Pk, the tractor cannot drive. It can be seen that the driving of agricultural tractor is realized by the interaction between the driving torque drive wheel and the ground, and the driving force is greater than the sum of rolling resistance and traction resistance.
