FIELD: transport engineering; railless vehicles.
SUBSTANCE: proposed trailer consists of frame and roll-under truck between which slewing circle is installed being made of upper and lower rings engaging through ball race. Curvilinear hollow shell of round section is secured on inner surface of upper ring which accommodates movable spherical body provided with parallel channels with check valves arranged in diametric plane of ring and rigidly installed on curvilinear rod whose ends are also rigidly connected to lower ring. Said rod engages with inner surface of hollow shell through sealing members in its end face parts. Shell is filled with working fluid. Some ends of channels of spherical body can be made conical.
EFFECT: improved reliability and stability of running of tractor trailers.
