The invention relates to the technical field of forced guiding, and discloses a semi-active-control hydraulic pressure guiding mechanism which comprises a vehicle body and a bogie, a front wheel pair and a rear wheel pair are arranged at the bottom of the bogie and connected together through a forced guiding connecting rod mechanism, and steering seats are fixed to the two sides of the top of the bogie. Hydraulic mechanisms are arranged on the two steering seats and comprise first hydraulic cylinders and second hydraulic cylinders, one ends of the first hydraulic cylinders are hinged to the bottom of the vehicle body, the other ends of the first hydraulic cylinders are hinged to the steering seats, one ends of the second hydraulic cylinders are hinged to the forced guiding connecting rod mechanisms, and the other ends of the second hydraulic cylinders are hinged to the steering seats; the first hydraulic cylinder is connected with the second hydraulic cylinder through the electromagnetic reversing mechanism. Effect and failure of the forced steering mechanism are controlled by controlling the electromagnetic directional valve, the problem of vibration transmission between a vehicle body and a wheel pair is solved on the basis of meeting curve passing performance, and stability and safety of a vehicle are greatly improved.

    本发明涉及迫导向技术领域,并公开了一种可半主动控制的液压迫导向机构,包括车体和转向架,转向架的底部设置有前轮对和后轮对,前轮对与后轮对之间通过迫导向连杆机构连接在一起,转向架顶部的两侧均固定有转向座,两个转向座上均设置有液压机构,液压机构包括第一液压缸和第二液压缸,第一液压缸的一端铰接在车体的底部,另一端铰接在转向座,第二液压缸的一端铰接在迫导向连杆机构上,另一端铰接在转向座上,第一液压缸通过电磁换向机构连接第二液压缸。通过控制电磁换向阀来控制迫导向机构的起效和失效,在满足曲线通过性能的基础上解决了车体和轮对之间振动传递的问题,极大提高了车辆的稳定性和安全性。
