The invention discloses a semitrailer frame reinforcing structure, which belongs to the technical field of semitrailer frames, The structure comprises a frame body, a suspension system and wheels; theframe body is of a convex arch structure; the wheels are mounted on the rear side of the frame body through the suspension system; a tensile reinforcing device is mounted at the bottom of the frame body along the longitudinal direction of the frame body and used for bearing bottom tensile force counteracting bearing deformation of the frame body; the frame body bears a load; deformation of the arched frame can be reduced preliminarily; bottom tension for bearing deformation of the frame body is borne and counteracted through the tensile reinforcing device at the bottom; deformation of the frame body is reduced greatly, and the bearing capacity of the frame body is guaranteed; the warping phenomenon of the frame body is avoided; a plurality of wheels are stressed jointly and evenly; the comprehensive service lives of the wheels are prolonged, and tire burst accidents are reduced; the installation is easy, the mass is small, and the semitrailer driving burden is not increased; the tensile reinforcing device is added, the thickness of a longitudinal beam web, an upper wing plate and a lower wing plate is reduced, and the semitrailer can be lightened.

    本发明公开一种半挂车车架加强结构,属于半挂车车架技术领域,包括车架、悬挂系统和车轮,车架呈上凸的拱形结构,车轮通过悬挂系统安装在车架的后侧,车架底部安装有沿车架纵向方向的抗拉加强装置,抗拉加强装置用于承受抵消所述车架承载变形的底部拉力。车架承受载荷,拱形车架可以初步减小形变,且通过底部的抗拉加强装置对车架承载变形的底部拉力进行承受和抵消,更大减小车架变形,保证其承载能力,避免车架翘曲现象,保证多个车轮共同均匀受力,延长车轮综合寿命,减少爆胎事故的发生;安装容易,质量小,不会增加半挂车行驶负担;增加抗拉加强装置,减少纵梁腹板及上下翼板的厚度,也可达到半挂车轻量化的目的。
