The invention discloses a self-steering system of a trailer and the trailer, the self-steering system is applied to the trailer with a frame, and relates to the technical field of automobiles. The self-steering system comprises a front steering assembly, a rear steering assembly and a push rod, a first rotating piece of the front steering assembly is rotationally connected to a first mounting base, a first eccentric base is fixedly arranged on the first rotating piece, and a second rotating piece of the rear steering assembly is connected to a second mounting base and is in driving connection with a rear steering wheel of the trailer. The two ends of the push rod are hinged to a first rotating shaft of the first eccentric base and a second rotating shaft of the second eccentric base respectively. Therefore, the tractor can drive the first rotating part to rotate during steering, the first eccentric seat pushes the second eccentric seat and the second rotating part to rotate synchronously through the push rod, the deflection direction of the front steering wheel of the tractor is opposite to the rotation direction of the rear steering wheel of the trailer, the turning radius can be reduced, and the situation of tire eating is effectively reduced.

    本发明公开了一种挂车的自转向系统及挂车,自转向系统应用于具有车架的挂车,涉及汽车技术领域。其中,自转向系统包括前转向组件、后转向组件和推杆,通过设置前转向组件的第一转动件转动连接于第一安装座,第一偏心座固设于第一转动件,后转向组件的第二转动件连接于第二安装座且和挂车的后转向轮驱动连接,第二偏心座固设于第二转动件,推杆的两端分别铰接于第一偏心座的第一转轴和第二偏心座的第二转轴。因此牵引车在转向时会带动第一转动件转动,使得第一偏心座通过推杆推动第二偏心座和第二转动件同步转动,且牵引车的前转向轮的偏转方向和挂车的后转向轮的转动方向相反,因此能够减小转弯半径,有效减少吃胎的情况出现。
