The invention discloses a trailer connecting structure in the technical field of trailer connection, and aims to solve the problem of poor safety between a tractor and a trailer in the prior art. The method comprises the steps that a certain inclination angle difference is allowed to exist between a trailer and a tractor through rotary connection of a traction limiting rod and a limiting shaft sleeve, even if the trailer turns over, the tractor can be prevented from being involved through the rotary connection relation, and the anti-rollover function is achieved; through sliding connection between the traction limiting rod and the limiting shaft sleeve, distance redundancy exists when the trailer and the tractor are impacted, the impact is buffered through the first damping elastic piece and the second damping elastic piece, and the probability that the tractor is impacted and damaged by the trailer or the trailer breaks the connecting structure to be disengaged from the tractor is reduced; meanwhile, the traction rod is used as a medium to allow rotation with an axle of the trailer, and the turning requirement is met; in conclusion, the safety is improved on the premise that the basic functions of connection and steering of the trailer are not affected, and the safety of the tractor and the trailer is guaranteed.

    本发明公开了一种拖挂车连接技术领域的拖车连接结构,旨在解决现有技术中牵引车与拖车之间安全性差的问题。其包括:通过牵引限位杆与限位轴套的转动连接,允许拖车与牵引车之间存在一定的倾角差,即便拖车翻车也可以利用该转动连接关系防止牵引车受到牵连,实现防翻车功能;通过牵引限位杆与限位轴套之间的滑动连接,使拖车与牵引车受到冲击时存在距离冗余,且利用第一减震弹性件和第二减震弹性件对冲击进行缓冲,降低牵引车被拖车冲击破坏或拖车拉断连接结构脱离牵引车的概率;同时以牵引杆为媒介允许与拖车的车桥之间转动,满足转弯需求;综上,在不影响拖车连接与转向的基本功能的前提下提高了安全性,保障了牵引车和拖车彼此的安全。
