Commercial vehicles are vehicles designed to transport people and goods in terms of design and technical characteristics. Commercial vehicles include all freight Cars and passenger cars with more than 9 seats. They are divided into five categories: passenger cars, trucks, semi-trailer tractors, passenger car incomplete vehicles, and truck non-complete vehicles. In the media of the entire industry, the concept of commercial vehicles is mainly defined from its own different uses, and it is customary to divide commercial vehicles into passenger cars and trucks.

Common Commercial Vehicle models

Common commercial vehicle models are: pickup, micro truck, light truck, micro passenger, self-supporting truck, truck, tractor, trailer, special vehicle
The difference between a tractor and a trailer
The front of the car with driving ability is called a tractor, and the car without traction driving behind is called a trailer. The trailer is towed by the tractor.
The difference between a tractor and a truck
As the name implies, a tractor is used to pull a trailer. The commonly mentioned truck should refer to a single truck. The biggest difference is that the front of the tractor and the cargo box are separated. They are connected together by a tractor. The front of the truck and the cargo box are integrated on a beam.
The difference between half hanging and full hanging
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 bears part of the weight of the trailer, this is the semi-trailer; the second In this case, 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, but does not bear the downward weight of the trailer. This is the full trailer.
