tractor

Power principle: The tractor burns a mixture of diesel and air through a diesel engine, converts the generated heat energy into mechanical energy, and transmits it to the walking mechanism and other working devices through the power transmission system.

Driving principle: Wheeled tractors rely on internal combustion engine power through the transmission system to provide driving torque to the driving wheels. The driving wheels exert a horizontal force on the ground to move backward, and the ground generates a horizontal reaction force of equal magnitude and opposite direction to the driving wheels, known as driving force. When the driving force is greater than the sum of rolling resistance and traction resistance, the tractor moves forward; The driving force of a tracked tractor is transmitted to the axle of the driving wheel through the tracks wound around the driving wheel, and then to the driving wheel. When the driving force is greater than the sum of rolling resistance and traction resistance, the supporting wheels roll forward on the surface of the tracks, causing the tractor to move forward.

Basic composition

Engine: It is the power source for tractor travel and operation, generally using a diesel engine, mainly composed of a crank connecting rod mechanism, a ventilation system, a fuel supply system, a lubrication system, a cooling system, a starting system, and a preheating device.

Chassis: It connects the engine with various systems and components, converting the engine's power into the driving and traction required for tractor operation. It mainly consists of multiple parts such as transmission system, steering system, braking system, and walking system.

Working device: usually classified as a part of the chassis, mainly used for towing, suspending, and driving agricultural machinery to carry out various agricultural machinery operations, including towing devices, power output devices, and hydraulic suspension devices.

Electrical equipment: mainly including generators, batteries, lighting systems, instrument systems, air conditioning systems, navigation systems, etc.
