The invention discloses a novel semitrailer main and follow-up steering system which comprises a front steering mechanism arranged at the front end of a semitrailer frame, a hydraulic driving system arranged on the middle section of the semitrailer frame, a rear steering mechanism arranged at rear wheels of a semitrailer and a steering remote controller arranged in a tractor cab. Wherein the front steering mechanism and the rear steering mechanism are both connected with the hydraulic driving system, and the hydraulic driving system is in communication connection with the steering remote controller. The invention has the advantages that: the rear wheels can synchronously follow the front tractor to steer, and can independently and actively steer under the control of the remote controller; the turning radius of a train can be greatly reduced, steering can be achieved in a smaller space, the adaptive capacity of the train can be improved, abrasion of tires can be reduced, and the running smoothness of the train can be improved.

    本发明公开了一种新型半挂车主、随动转向系统,包含设置在半挂车车架前端上的前转向机构、设置在半挂车车架中段上的液压驱动系统、设置在半挂车后车轮处的后转向机构以及设置在牵引车驾驶室内的转向遥控器;其中,前转向机构及后转向机构均与液压驱动系统相连,液压驱动系统与转向遥控器通信连接。本发明的优点有:既能让后车轮跟随前面牵引车同步随动转向,又能让后车轮在遥控器的控制下独立主动转向;能大幅减小列车的转弯半径,能够在更小空间内实现转向,不仅可以提高车辆适应能力,还可以减小轮胎的磨损以及提高车辆行驶的平顺性。
