摘要
针对传统液压制动系统笨重、耗能大等缺点,通过XBW(线控)技术对其进行改进。采用理论分析、建模仿真和实验测试等方法,设计了无油化、全电控的制动系统。系统包括踏板模拟器、控制模块和凸块制动器三部分。踏板模拟器采用连杆传动机构,变旋转运动为直线运动,采集驾驶员作用在踏板上的指令,经控制模块分析处理后,由电机驱动器控制步进电机工作,驱动凸块制动器实现制动。通过搭建实验台测试,表明系统可以稳定运行,达到了预期制动命令,实现了制动系统轻量化、模块化和节能减排。
In view of the shortcomings of the traditional hydraulic braking system,such as great bulk and large energy consumption,it was improved by the XBW（ X- by- wire） technology. By using the method of theoretical analysis,modeling and simulation and experimental testing,By using the method of theoretical analysis,modeling and simulation,and experimental testing,the non- oil,fully electronically controlled braking system was designed. The system consists of three parts： the pedal simulator,the control module and the bump brake.The pedal simulator with connecting rod drive mechanism converts rotational motion into linear motion. The driver＇s instructions on the pedal are collected,analyzed and processed by controlling module,and used to control stepper motor by motor driver to realize braking by driving bump brake. Test by experiments showed that the system operates stably,which performed expected braking commands,and its lightweight,modularization,energy-saving and emission reduction is realized.
