The trailer comprises a frame, a traction connecting device, a connecting back plate, a damping element, a steering swing arm and a wheel system, the traction connecting device adopts a double-traction-lever mode, two traction rods are installed at the bottom of the frame, and hook assemblies are installed at the front ends of the traction rods. The hook assembly is connected with a tractor through a bolt type mechanical connection structure. Connecting back plates are installed on the left side and the right side of the trailer frame respectively, a damping element is installed on each connecting back plate, the bottom of the shaft end of each damping element is fixedly connected with a steering swing arm through a tapered roller bearing and a bearing locking nut, and a wheel system is installed on the steering swing arm through a tire shaft. The wheel system achieves degree steering through a tapered roller bearing at the connecting end of the steering swing arm and the damping element. According to the invention, a trailer dragged by a crawler-type armored vehicle or a wheeled all-terrain vehicle can have a pivot steering function.
