FIELD: railway transport. SUBSTANCE: proposed system serves for coupling or connecting two opposite ends of two load-carrying structures of car on one and the same car bogie. Load-carrying structure has V-shaped front end hinge coupled with car bogie and open rear end formed by two parallel cantilevers. System has cross turnable crossmember with intake bracket on each end. V-shaped front end of first load-carrying structure of car and turnable crossmember are mounted on common articulated unit installed on car bogie center plate. Each intake bracket has device for fixing end of corresponding cantilever of second load-carrying structure of car. End of each cantilever has device for connection with intake brackets of corresponding end of crossmember. EFFECT: provision of quick connection of coupling of rear end of adjoining load carrying structure of car with bogie. 10 cl, 8 dwg
