对仿步行式气垫车辆的转向进行了运动分析和受力分析，给出了仿步行式气垫车实现稳定转向的条件。仿步行式气垫车用双向液压马达驱动，通过分－集流阀改变双侧液压马达流量来控制内、外侧轮的正、反转，从而实现车辆的转向。提出用同步阀控制两侧半步行轮的同步运动、在气垫车前部安装导向盘等措施来保证其直线行驶性能。 The motion analysis and force analysis of the imitation walking air cushioned vehicle are given, and the conditions for the steady steering of the imitation walking air cushion vehicle are given. Imitation walking air-cushion vehicle with two-way hydraulic motor driven by sub-collection valve to change bilateral hydraulic motor flow to control the inside and outside the wheel positive and negative, in order to achieve the steering of the vehicle. It is proposed to control the synchronous motion of the semi-walking wheels on both sides with the synchronous valve and to install the steering wheel in the front part of the air-cushioned vehicle to ensure the straight-line running performance.
