A semitrailer is a trailer with a axle behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and a coupling device to transfer horizontal or vertical force to the tractor. Compared with "monomer" cars, semi-trailers can improve the comprehensive economic benefits of road transport. Transportation efficiency can be increased by 30-50%, cost reduced by 30-40%, and oil consumption reduced by 20-30%
