The invention provides a rear axle steering coiled tubing operation roller semitrailer. The semitrailer comprises a frame, a roller, a rear axle assembly and a rear axle steering mechanism, wherein the roller, the rear axle assembly and the rear axle steering mechanism are arranged on the frame; the rear axle steering mechanism comprises an upper supporting seat, a turntable bearing, a lower supporting seat and a steering driving assembly; the steering driving component and the upper supporting seat are arranged on the frame, the turntable bearing is respectively connected with the upper supporting seat and the lower supporting seat, and the lower supporting seat is fixedly connected with the rear axle assembly; the steering driving assembly is connected to the lower supporting base so as to drive the lower supporting base to rotate relative to the upper supporting base and drive the rear axle assembly to rotate. The steering driving mechanism is adopted to drive the lower supporting seat to achieve steering of the rear axle assembly, the relative turning angle of the frame and the wheels is large, the turning radius of the semitrailer is reduced, the reliability of steering driving is improved, the safety of the whole semitrailer is improved, and the driving intensity of the semitrailer is reduced.

    本发明提出一种后桥转向连续管作业滚筒半挂车。该半挂车包括:车架、以及设置于所述车架的滚筒、后桥总成和后桥转向机构;所述后桥转向机构包括上支撑座、转盘轴承、下支撑座和转向驱动组件;所述转向驱动组件和所述上支撑座设置于所述车架,所述转盘轴承分别与所述上支撑座和下支撑座连接,所述下支撑座与所述后桥总成固定连接;所述转向驱动组件连接于所述下支撑座,以驱动所述下支撑座相对于所述上支撑座旋转,并带动所述后桥总成转动。通过采用转向驱动机构驱动下支撑座实现后桥总成转向,车架与车轮相对转角大,减小了半挂车的转弯半径,提高了转向驱动的可靠性,提高了整体车辆的安全性,降低了车辆的驾驶强度。
