FIELD: transport machine building.
SUBSTANCE: system for fixation of pivot of semitrailer on vehicle comprises balancer (16) and, in fact, horizontal rigid engaging structure (33), intended for imparting direction of vertical movement of receiving compartment (5), maintaining it in required position above lifting system (7) in horizontal plane and damping forces acting on it. Longitudinal rigid engaging structure (33) is hingedly engaged with receiving compartment (5) and with vehicle in order to absorb longitudinal forces acting on them. Balancer (16) comprises preloaded springs (21a), which absorb damping forces acting on balance beam (16), when receiving compartment (5) is temporarily inclined relative to horizontal plane. Lifting system (7) for lifting of receiving compartment (5) is installed with possibility of rotation on railway car (4) on axis (15) of rotation located across longitudinal axis of vehicle.
EFFECT: disclosed is a system for fixing a semitrailer pivot on a vehicle.
