摘要
汽车转向系统是用于改变或保持汽车行驶方向的专门机构,以其卓越的性能,成为转向技术研究的重点和热点。其作用是使汽车在行驶过程中能按照驾驶员的操纵要求而适时地改变其行驶方向,并在受到路面传来的偶然冲击及汽车意外地偏离行驶方向时,能于行驶系统配合保持汽车能继续稳定行驶。因此,转向系统的性能直接影响着汽车的操纵稳定性和安全性。本文针对电子助力转向系统在汽车上应用的日趋广泛和普及,对其原理、工作特点,各部件的组成及其配合进行解剖和分析,并对电动助力转向系统试验台架进行介绍,分析了EPS关键技术的性能特点以及发展趋势。
关键字:EPS,转向系统,发展,工作原理,基本结构
Abstract
The car turned system is used to change or remain with the car in the direction of specialized agencies. its function is to the car in the process to be in accordance with the pilot's control demand and time to change its speed and direction under the road to the shocks and the car accident knocked off the road in be able to keep the road system to continue steady cooperation. therefore, to the system of the performance of the direct impact on the manipulation of stability and security. The paper against the power steering system in the car is wide application of standards and popularization of its principles, work, and the parts of the anatomy and coordination on and analysis, and the electric power steering system a review.

Keywords:EPS,steering system,tracert,Makefile,test-bed
