Introduction

Tractor for mechanical traction and drive homework finish the self-propelled engine and mobile operations. Can also be fixed homework motivation. By the engine, transmission, walk, turn, hydraulic suspension, power output, electrical instrumentation, pilot control and traction device such as a system or component. By the transmission system of engine power to the drive wheels, make the tractor driving, in real life, are based on common rubber belt as the transmission medium. According to the function and use tractors, such as agriculture, industry and special purpose; According to the structure type of wheel, crawler, ship the tractor and the chassis.

Principle

Travel is to rely on internal combustion engine power through the transmission system, make driving wheel drive torque Mk, get the driving torque of driving wheel through the tire pattern and tire surface to the ground again small, or the level of backward reaction (tangential force), and a driving force to the level of the equal and opposite rice force Pk, the Pk rice force is driving the tractor driving forward the driving force (also known as feed for propulsion). When driving force Pk enough to overcome before and after the wheel rolling resistance and brings forward tools traction resistance, the tractor is moving forward. If the driving wheel its ground, namely the driver Pk is equal to zero, the driving wheel only in situ idling, tractor cannot drive; If the rolling resistance is greater than the sum of the traction resistance and driving force Pk, the tractor can’t drive.
