Working Principle

The tractor of the trailer is connected to the trailer through the traction device. The engine of the tractor provides power to drive the wheels to rotate and generate traction. When the tractor moves forward or backward, the traction device drives the trailer to move together. At the same time, both the tractor and the trailer are equipped with braking systems, steering systems, etc. to ensure the safety and controllability of the vehicle. When braking, the braking systems of the tractor and the trailer will work at the same time to slow down or stop the vehicle; when turning, the steering operation of the tractor will be transmitted to the trailer through the traction device, so that the trailer turns in the direction of the tractor.
