The invention discloses a hinge mechanism for hinging a special vehicle, which comprises a steering oil cylinder, a transverse adjusting oil cylinder, a telescopic oil cylinder, a pitching oil cylinder, a locking mechanism, a telescopic rod, a torsion seat, a connecting seat, a steering hinge seat and a connecting seat, wherein the torsion seat is matched with the connecting seat through a shaft hole, the connecting seat is driven by the telescopic oil cylinder to longitudinally move on a cylindrical slideway of the torsion seat, and the length of the hinge mechanism is adjusted; the connecting seat is connected with the steering hinge seat through a pin shaft, steering motion is achieved through telescoping of the steering oil cylinder, transverse position control of a hinge point of the steering oil cylinder and the telescopic oil cylinder can be achieved through the transverse adjusting oil cylinder, and the width of the hinge mechanism is changed; the locking mechanism is matched with the telescopic rod to achieve locking of the hinge mechanism under the working condition that the rotating angle is not changed, and the rigidity of the steering mechanism is enhanced; and the steering hinge seat is connected with the connecting seat through a pin shaft, and pitching motion is achieved through the pitching oil cylinder. Parameters of the hinge mechanism are optimized, the rigidity of a steering mechanism is enhanced, the stability of a vehicle is improved, and the load of an oil cylinder is reduced; and through transverse and longitudinal adjustment, the large turning angle is achieved under the condition that the front and rear vehicle bodies are wide.

    一种特种铰接车辆的铰接机构,包括转向油缸、横向调节油缸、伸缩油缸、俯仰油缸、锁紧机构、伸缩杆、扭转座、连接座、转向铰接座和连接座。扭转座与连接座通过轴孔配合,通过伸缩油缸驱动实现连接座在扭转座的圆柱滑道上纵向运动,调节铰接机构长度;连接座与转向铰接座销轴连接,通过转向油缸伸缩实现转向运动,通过横向调节油缸可实现转向油缸与伸缩油缸铰点横向位置控制,改变铰接机构宽度;通过锁紧机构与伸缩杆的配合实现在转角不变的工况下铰接机构的锁死,增强转向机构的刚度;转向铰接座与连接座销轴连接,通过俯仰油缸实现俯仰运动。本发明优化了铰接机构参数,增强转向机构的刚度,提高车辆稳定性,减小油缸负载;通过横纵向调节,满足了在前后车体较宽情况下大转角的实现。
