The invention discloses a multi-axle trailer capable of steering independently. The multi-axle trailer comprises a frame, wheels, a suspension system, a steering system, a braking system and an axle assembly. The frame comprises a front frame and at least one rear frame; the front frame and the rear frame are hinged through an adapter; the steering system comprises a bogie, a steering arm, a transverse pull rod, a longitudinal pull rod, a pull rod fixing frame, a double-rod oil cylinder and a steering hydraulic system. The longitudinal pull rod is an integrated rod body and/or a split type rodbody. The multi-axle trailer has the beneficial effects that through the split frame composed of the front frame body and the multiple rear frame bodies, the wheels can be evenly arranged, and uniform load transmission is guaranteed. The longitudinal pull rod of the steering system is arranged to be the split type rod body and the double-rod oil cylinder, the telescopic matching of the adjacent double-rod oil cylinders can be used for driving a certain single steering arm to rotate, and therefore steering of a single set of wheels corresponding to the steering arm is achieved, and the turningradius is reduced.

    本发明公开了可独立转向的多轴挂车,包括车架、车轮、悬挂系统、转向系统、制动系统和车桥总成;车架包括前车架和至少一个后车架;前车架与后车架之间通过转接头铰接;转向系统包括转向架、转向臂、横拉杆、纵拉杆、拉杆固定架、双杆油缸和转向液压系统;纵拉杆为一体式杆体和/或分体式杆体。本发明的有益效果是:通过前车架和多个后车架组成的分体式车架,可均匀设置车轮保证载荷传递的均匀。通过将转向系统的纵拉杆设置为分体式杆体和双杆油缸,利用相邻双杆油缸的伸缩配合可驱动某单个转向臂的转动,从而实现该转向臂对应的单组车轮转向,减小转弯半径。
