汽车电动助力转向系统 【摘要】 本论文主要阐述了汽车电动助力转向系统在我们的生活当中汽车使用过程中带来的方便作用和它的工作原理以及维护维修方法。汽车工业作为我们的支柱产业,在国民经济中起着重要作用。汽车转向器作为汽车的重要零部件,其性能的好坏直接影响着汽车行驶的安全性和可靠性。我国在发展汽车零部件的政策规划中,已将转向器列为优先发展的25种汽车关键零部件之一。随着世界上电子技术的迅猛发展,汽车转向系统已经从传统机械转向、液压助力转向、电控液压助力转向,发展到电动助力转向系统(Electric Hydraulic Power Steering)简称EPS,最终还将要过渡到线控转向系统。 汽车电动助力转向系统是现代汽车中比较常规的配置,是一种直接依靠电机提供辅助扭矩的动力转向系统。主要是由于它的工作效率高,能量消耗少,系统内部采用刚性连接,反应灵敏,滞后小,驾驶员的“路感”好,结构简单,质量小,系统便于集成;整体尺寸减小,省去了油泵和辅助管路,总布置更加方便;液压元件,对环境污染少。EPS将必威体育精装版的电力电子技术和高性能的电机控制技术应用于汽车转向系统,能显著改善汽车动态性能和静态性能、提高行驶中驾驶员的舒适性和安全性、减少环境污染等。因此,该系统一经提出,就受到许多大汽车公司的重视,并进行开发和研究。 关键词:电动助力 安全性 可靠性 效率高 消耗少 反应灵敏 Abstract: The caption mainly expounds the auto electric power steering system in our life car use process the convenience and its role the working principle and maintenance method.The auto industry as I had a pillar industry,in the national economy plays an important role.Automobile redirector of car parts as important,the performance of a direct impact on the security and reliability of the car.In developing automobile parts policy planning, already will steering gear as priority development of 25 kinds of one of the key automotive spare parts.With the world on the rapid development of electronic technology,autoSteering system have traditional mechanical and Hydraulic Steering from Power Steering,Electric control Hydraulic Power Steering,the development of the Electric Power Steering system (Electric Hydraulic Power Steering,the abbreviation EPS),eventually will transition to the wire control Steering system。 The auto electric power steering system is the modern car relatively routine configuration,is a direct rely on motor torque to provide auxiliary power steering system.Is mainly due to its high efficiency less energy consumption; The internal system rigid connection sensitive reaction,lag,the pilot of the small way feeling;Simple structure quality is small; System can reduce the overall integration,size and tell the oil pump and auxilia
