The bolt assembly is applied to an unmanned tractor and comprises a bolt, one end of the bolt is a plug used for being connected with a trailer tripod, and the side wall of the bolt is provided with a guide groove extending in the axial direction of the bolt; the guide protrusion is arranged on the outer side of the plug pin, and the guide protrusion is matched with the guide groove to prevent the plug pin from rotating around the axis of the plug pin. According to the plug pin assembly, the plug pin can be prevented from rotating around the axis of the plug pin through cooperation of the guide protrusion and the guide groove, that is, when the plug pin is located at the working position, the plug pin does not deflect, and therefore it can be ensured that the position of the plug pin is stable, and stability and reliability of connection between the plug pin and a trailer tripod are ensured; safety accidents caused by separation of the bolt and the trailer tripod in the trailer process can be prevented.

    本申请公开的插销组件,应用于无人驾驶牵引车,包括:插销,所述插销一端为插头,用于连接拖车三角架,所述插销的侧壁设有沿其轴向延伸的导向槽;导向凸起,设于所述插销外侧,所述导向凸起与所述导向槽配合以防止所述插销绕自身轴线旋转。本申请的插销组件,通过导向凸起与导向槽配合可防止插销绕自身轴线旋转,也就是说,当插销处于工作位时,插销不发生偏转,因此可确保插销位置稳定,从而确保插销与拖车三角架连接的稳定性与可靠性,可防止拖车过程中插销与拖车三角架脱离发生安全事故。
