FIELD: transport.SUBSTANCE: invention relates to trackless ground transport facilities intended for transportation of both light small and heavy long equipment and other cargoes, particularly, to centrepoint suspension of trailers and semitrailers. Semitrailer comprises frame resting on connection beam. Balancing wheel carriers are mounted on beam ends and comprises frame and wheel axles. Connection beam is composed by two wavy rails interconnected by crossbars with three recesses and two flanges located there between. Frame rests on connection beam at its central recess. Balancing wheel carrier attachment seats are made on bottom surface of extreme recesses. Distance between flames equals overall size of balancing wheel carrier frames along semitrailer axis. Distance between outer walls of connection beam flanges is smaller than that between inner side surfaces of the wheels. Distance between inner walls of connection beam flanges exceeds semitrailer frame width in connection beam area.EFFECT: higher efficiency.4 cl, 5 dwg |
