一些特殊结构的轮胎式工程机械,其驾驶员无法直接观察转向轮的转向角度。在工程机械攀爬平板拖车时,若不能掌握转向轮的转向角度,极易发生侧翻事故。本文阐述的转向角度指示系统,旨在给工程机械驾驶员提供转向轮转向角度信息,给驾驶员准确控制转向角度提供方便,以提高工程机械转向操纵的安全性。1.系统组成转向轮转向角度指示系统由电压信号转换模块、电压信号处理模块、步进电动机走针模块等组成,如图1所示。在转向轮上安装1个随转向
Some special structure of tire-type construction machinery, the driver can not directly observe the steering wheel steering angle. When climbing in the construction machinery flatbed trailer, if you can not grasp the steering wheel steering angle, prone to rollover accident. This paper describes the steering angle instruction system designed to provide construction machinery pilots steering angle information to provide accurate control of the steering angle to provide a convenient driver to improve the safety of construction machinery steering. 1. System Components Steering wheel steering angle indication system consists of voltage signal conversion module, voltage signal processing module, stepper motor walking pin module and other components, as shown in Figure 1. Install one on the steering wheel with steering
