Background
With the great investment of road construction, road transportation has become the main transportation mode in China. The tractor serves as main equipment for road transportation and is widely applied due to the advantages of strong specialization, large loading capacity and quick transportation. The tractor is a common large truck or semi-trailer which is pulled by a tool between a vehicle head and a vehicle box, the vehicle head with driving capability in the front is called the tractor, the vehicle without the driving capability in the back is called a trailer, and the trailer is dragged away by the tractor. The connection mode of the tractor and the trailer has two types: the first is that the front half of the trailer is put on a traction saddle above the rear section of the tractor, and the bridge behind the tractor bears a part of the weight of the trailer, namely the semitrailer; the second is that the front end of the trailer is connected to the rear end of the tractor, and the tractor only provides forward pulling force to drag the trailer, but does not bear the downward weight of the trailer, and the trailer is fully hung.
In the case of semi-tractors, the frame structure design has matured over time, although not a very complex and attractive component. However, in order to increase profitability, the development of the frame has been mainly focused on both the volume of the tractor trailer and the reduction in weight. At present, the frame structure is a groove-shaped steel structure, and the volume of the trailer is difficult to lift.
