The invention provides a trailer longitudinal beam which comprises a bearing section, a lap joint section and a gooseneck section, and the lap joint section is connected to the bearing section through the gooseneck section. The top of the bearing section and the top of the lap joint section are each provided with a first energy absorption connecting part, and each first energy absorption connecting part comprises a mounting frame, a connecting cover and a plurality of solid rubber balls. According to the trailer longitudinal beam and the trailer, the first energy absorption connecting parts are arranged on the bearing section and the lap joint section of the trailer longitudinal beam, when the trailer bumps, downward impact force is brought by bumping, the impact force downwards presses a connecting cover, the connecting cover downwards extrudes a solid rubber ball, and the solid rubber ball is tightly connected with the first energy absorption connecting parts; wherein the rubber balls on the upper layer and the lower layer and the mounting frame and the connecting cover extrude each other, and impact force is buffered and absorbed through mutual friction between the rubber balls and deformation of the rubber balls, so that the impact force is prevented from directly acting on the longitudinal beam, and the service life of the longitudinal beam is prolonged.

    本发明提供一种挂车纵梁,包括:承重段、搭接段和鹅颈段,所述搭接段通过鹅颈段连接于所述承重段上;所述承重段和搭接段的顶部均设置有第一吸能连接部,所述第一吸能连接部包括安装框、连接盖和若干实心橡胶球。本发明提供的挂车纵梁以及挂车,通过在挂车纵梁的承重段和搭接段上设置有第一吸能连接部,当挂车出现颠簸时,颠簸带来向下的冲击力时,冲击力向下压连接盖,连接盖向下挤压实心橡胶球,其中上下层的橡胶球之间以及与安装框和连接盖之间相互挤压,通过橡胶球之间相互的摩擦以及自身的形变对冲击力进行缓冲吸收,从而避免冲击力直接作用在纵梁上,从而延长纵梁的使用寿命。
