摘　　要：为提高支架搬运车的通过性能,提出了一种适用于整体式支架搬运车的半自动全轮转向系统。转向系统采用主、副转向器同时控制,主转向器控制前轮转向,实现基本转向功能。同时操作主、副转向器可实现前、后轮全轮转向;单独操作副转向器可实现后轮的单独转向,方便装卸支架时整车状态的调整。为防止外力作用下后轮转向的误动作,影响整车行驶稳定性,在后轮设置了双向液压锁。基于整车操控稳定性,对全轮转向时,后轮的转向控制策略进行了研究,通过控制中心对驾驶员输入的转向角进行补偿或控制,保证四轮转向的稳定性。该转向系统的设计可为整体式支架搬运车的转向系统设计及优化提供了参考。In order to improve the passage capacity of the bracket carrier,a semi-automatic all wheel steering system suitable for integral support carrier was proposed.The steering system used the primary and secondary steering gear to control at the same time,and the main steering gear controlled the front wheel steering to realize the basic steering function.At the same time,the main and auxiliary steering gear could realize the front and rear wheel steering.The separate operation of the secondary steering gear could realize the independent steering of the rear wheel,which was convenient for the adjustment of the vehicle state when loading and unloading the bracket.In order to prevent the misoperation of rear wheel steering under the action of external force and affect the driving stability of the whole vehicle,two-way hydraulic lock was set in the rear wheel.Based on the vehicle handling stability,the control strategy of the rear wheel steering was studied.The steering angle input by the driver was compensated or controlled by the control center to ensure the stability of four-wheel steering.The design of the steering system can provide a reference for the design and optimization of the steering system of the integral support carrier.
