[0002] With the rapid development of the times and the continuous improvement of logistics level, the goods that need to be transported are also increasing. Ordinary trucks can no longer meet the transportation needs of a large number of goods. At this time, semi-trailers with higher transportation efficiency have become the first choice for cargo transportation. A semi-trailer is a trailer with an axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers generally have a heavy load and require high strength and load-bearing capacity of the axle. The connection between the existing trailer axle tube and the suspension system is usually to weld an axle support on the axle tube to fix the leaf spring or guide arm to achieve the purpose of fixing the axle and preventing rolling. However, welding is prone to thermal damage and deformation defects on the axle tube, which increases costs and affects the overall service life of the axle, resulting in a decline in the economic benefits of the enterprise, which in turn easily affects the convenience of use of the entire axle tube.
