For semitrailer the problem of the influence of geometric dimensions, power characteristics of springs system modernized and elastic connection of the tractor and semitrailer on its transverse oscillation angle. Described transverse angular oscillation of the sprung semitrailer obtained ratio, taking into account the influence of the main characteristics of dynamic spring’s system, geometric dimensions of the trailer for defining parameters of vibration. It is shown that the use of the upgraded system connect the tractor and semitrailer influences the amplitude and frequency of its oscillations that ultimately leads to reduction of dy-namic loads on components trailer or equipment that it carries.
