What is Tractor Truck?
The front vehicle with driving capability is called a tractor, and the rear vehicle without driving capability is called a trailer. The trailer is towed by a tractor. There are two ways to connect the tractor and the trailer: the first is that the front half of the trailer is placed on the traction saddle above the rear section of the tractor, and the bridge behind the tractor receives part of the weight of the trailer, which is the semi-trailer; The first is that the front end of the trailer is connected to the rear end of the tractor. The tractor only provides forward pulling force and drags the trailer away, but does not bear the downward weight of the trailer. This is full suspension.

Classification of tractor truck:
At present, the tractors are mainly divided into two categories: full tractors and semi-trailers.
1. Semi-trailer tractor: The front half of the trailer is placed on the traction saddle above the rear section of the tractor. The bridge behind the tractor bears part of the weight of the trailer.
2. Full-trailer tractor: The front end of the trailer is connected to the rear end of the tractor. The tractor only provides forward pulling force and drags the trailer away, but does not bear the downward weight of the trailer.
The role of the tractor truck:
1. Anti-slip: Prevent the idling of the drive wheels when driving on wet roads such as snow, so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system can ensure smooth acceleration performance to prevent the vehicle from moving laterally or tailing due to the slipping of the driving wheels.
2. Flexibility: When the car is towed, the vehicle train has better mobility flexibility.
3. Reliable work: ensure that the traction car and trailer are connected reliably, conveniently and quickly.
4. Stability: The traction can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact load.
