FIELD: transport engineering; railless vehicles. ^ SUBSTANCE: proposed large-capacity trailer-train includes prime mover with pneumatic brake system and fifth wheel coupler engaging with pivot rigidly secured on frame and semitrailer also provided with pneumatic brake system connected with pneumatic brake system of prime mover. Frame of semitrailer in hinge-connected with rod of pneumatic cylinder arranged coaxially with longitudinal axis of its symmetry. Cylinder is hinge secured on pivot movably arranged in guides of semitrailer frame and spring-loaded relative to frame. Underpiston space of cylinder arranged from side of pivot is connected to pneumatic brake system of said semitrailer by means of pipeline. ^ EFFECT: improved safety in operation of large-capacity trailer-trains. ^ 3 dwg |
