Nanchang wheeled tractorManufacturer - The main factors affecting the driving of tractors in Nanchang
(2) Traction resistance refers to the resistance that a tractor must overcome to drive agricultural machinery during operation. It is equal to the traction force transmitted by the tractor to the agricultural machinery through a connecting device. Since traction is equal to driving minus rolling resistance, increasing driving force and reducing rolling resistance are effective measures to improve traction.
(3) The driving force is the horizontal reaction force exerted by the road on the driving wheels. Therefore, the magnitude of the driving torque Mk transmitted by the internal combustion engine to the driving wheels through the transmission system indicates that the driving force Pk of the tractor is also greater. However, since Mk is determined by the power of the internal combustion engine, Pk is also limited by the power of the internal combustion engine. At the same time, Pk is limited by soil conditions and cannot be increased, because when the reaction force of the soil, that is, the driving force Pk, increases to a certain extent, the soil is destroyed, the driving wheel slips severely, and the driving force Pk cannot be increased any further. We call the large reaction force that soil can produce on the driving wheel "adhesion". From this, it can be seen that the large value of driving force Pk is not only limited by the internal combustion engine rate, but also by soil adhesion, and cannot increase the country.
