A semi-trailer trailer for double trailers comprises a traction trailer head and trailers, two movable traction seats on a first trailer or a second trailer can move in the central axis direction and used for adjusting the distance between the two movable traction seats, and the movable traction seats are installed at the front ends and the rear ends of the trailers so that the distance between the two movable traction seats can be adjusted. The traction seats can be matched with each other in a pulling and hanging manner, and the specific positions of the movable traction seats on the trailers can be adjusted according to use requirements, so that the total length between the two trailers can be adjusted, and the defects of the double trailers in a no-load state are overcome to a certain extent; the trailer can independently move in the horizontal state through cooperation of the telescopic rod and the supporting wheels at the bottom, the trailer is controlled to be in pull-hanging cooperation with the first traction base on the traction vehicle head, and compared with a driving traction vehicle head, the operation mode is simpler.

    一种双挂车用半挂拖车,包括牵引车头和拖车,所述第一拖车或第二拖车上的两个所述活动牵引座能沿中轴线方向活动,用以调节两个所述活动牵引座之间的间距,通过在拖车的前后两端安装可活动的牵引座,并且牵引座之间可相互拖挂配合,可以根据使用需求,调整活动牵引座在拖车上的具体位置,使两个拖车之间的总长度可调整,在一定程度上弥补双挂车在空载状态下的缺点,同时,牵引座上设置可收缩的伸缩杆,拖车可独立的通过伸缩杆及底部的支撑轮配合保持水平状态移动,将控制拖车与牵引车头上的第一牵引座拖挂配合,相较于驾驶牵引车头,在操作方式上更加简单。
