摘要
为解决传统液压转向系统转向半径过大、通过性差的问题,本文以5轴军用越野汽车为例,提出一种基于PLC控制的电控液压多轮转向系统。该系统具备前组和多组两种工作模式,同时兼具故障诊断与处理、人机交互、零位标定等功能。该系统减小了车辆的转弯半径、改善了车辆的通过性,最大程度提升了系统的控制精度和响应速度,改善了人机交互体验,满足了车辆在不同场地内的使用需求。
In order to solve the problem of excessive steering radius and poor passability of the traditional hydraulic system,this paper takes a five-axle vehicle as an example and proposes an electronically controlled hydraulic multi-wheel streeling system based on PLC control.The system has two working mode,including front mode and multiple mode,and also has functions as fault diagnosis、human-computer interaction,and zero calibration.The system reduces the steering radius of the vehicle,improves vehiclepassability,promotes the control accuracy and response speed of the system extremely,improves the human-computer interaction experience,and meets the needs of the vehicle in different areas.
