It is used to reduce shock on the semitrailer beam and the transported goods when passing through ditches during transportation, which can effectively protect the semitrailer beam and the transported goods.

Among them, a semi-trailer suspension device with application number "CN202121838277.3" can further optimize the shock absorption of the semi-trailer frame through the piston assembly, and at the same time take away a large amount of heat generated in the shock absorption process in the suspension mechanism through the flow of hydraulic oil, continuously and stably cool the suspension mechanism, and extend the service life of the suspension mechanism. Further search found that the variable rigidity semi-trailer suspension mechanism with application number "CN201120242882.4" can effectively ensure the stability of the semi-trailer when it is driving on uneven roads, and can make the force direction of each tire always perpendicular to the ground, so that the tire wear is even, thereby improving the service life of the tire.

However, the above two methods still have certain shortcomings when used. Since their widths are fixed and cannot be adjusted, they can only be adapted to semi-trailers with one frame width, and it is not convenient to provide a width adjustment function with higher adaptability.
