The invention discloses a novel semitrailer frame and belongs to the technical field of semitrailers. The semitrailer frame comprises a semitrailer frame body including a first frame and a second frame; wheels are arranged at the bottom of the second frame; a second hydraulic cylinder is arranged on the surface of the first frame; the tail end of the second hydraulic cylinder is mounted on the first frame in a hinged manner; and a connecting frame is arranged at the output end of the second hydraulic cylinder. With an auxiliary wheel mechanism, traffic accidents caused by sudden tire burstingin the running process of the semitrailer are avoided, the running safety of the semitrailer is guaranteed; meanwhile, convenience is provided for follow-up tire replacement; with a folding frame, inthe empty vehicle running process, the shortened vehicle frame transportation efficiency is high, the defects that the turning radius is too large and the like because an overlong vehicle frame runs are overcome and thus the running efficiency is reduced are overcome; the transportation time can be shortened through the folding frame, so that the transportation efficiency is improved.

    本发明公开了一种新型半挂车车架,属于半挂车技术领域,包括半挂车车架本体,所述半挂车车架本体包括第一车架和第二车架,所述第二车架底部设有车轮,所述第一车架的表面设置有第二液压缸,所述第二液压缸末端通过铰接的方式安装在第一车架上,所述第二液压缸的输出端设置有连接架,本发明通过设置辅助轮机构,避免了半挂车在行驶过程中突然发生爆胎时引发交通事故,保证了车辆的行驶安全,同时提供了后续换胎的便利;本发明通过设置的折叠式车架,在空车行驶中,缩短的车架运输效率高效,避免了过长的车架在行驶造成了转弯半径过大等弊端,导致运行效率降低,通过折叠式车架可缩短运输时间,从而提高了运输效率。
