1. Anti-skid: Prevent the idling of the driving wheels when the vehicle is driving on wet and slippery roads such as snow, so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system ensures smooth acceleration and prevents the vehicle from rolling or drifting due to slippage of the drive wheels.
2. Flexibility: The car train has better maneuverability when pulling the car.
3. Reliable work: to ensure reliable, convenient and rapid disconnection between the tractor and the trailer.
4. Stable: The traction force can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact load.
