摘　　要：为提高某越野车的最小转弯半径和操纵稳定性,结合后悬架机构设计了一种新型的后轮液压转向系统,构建了后轮转向系统的机械结构及液压油路,并分析了在进行四轮转向的过程中液压缸如何移动活塞杆,通过AMESim软件验证了该液压系统在转向过程和对中过程方案的可行性。仿真结果表明,后轮液压转向系统具有较高的灵敏度。The rear wheel hydraulic steering system was designed combined with the rear suspension structure in order to improve minimum turning radius and stability at high speed of an off- road vehicle. The mechanical structure and the principle of hydraulic circuit are described in detail. The feasibility of the way to turn round and align was verified through the software of AMESim,and the results of simulation show the rear wheel steering system has a good sensitivity.
