A、汽车电动助力转向器简介电动转向系统（EPS，Electrie Power Steering）是未来转向系统的发展方向。

该系统由电动机直接提供转向助力，省去了液压动力转向所必需的动力转向油泵、软管、液压油、传送带和装于发动机上的皮带轮，既节省能量，又保护了环境，另外，还具有调整简单、装置灵活以及无论在何种工况下都能提供转向助力的特点。

正是有了这些优点，电动转向系统作为一种新的转向技术，将挑战大家都非常熟知的、已具有50多年历史的液压转向系统。

1、电动转向系统电动转向系统是于20世纪80年代中期提出来的。

该技术发展最快、应用较成熟的当属TRW转向系统和Delphi Saginaw（萨吉诺）转向系统，而Delphi Saginaw（萨吉诺）转向系统又代表着转向系统发展的前沿。

她是第一个于20世纪50年代把液压助力转向系统推向市场的，从此以后，Delphi转向发展了技术更加成熟的液压助力系统，使大部分的商用汽车和约50%的轿车装备有该系统。

现在，Delphi 转向系统又领导了汽车转向系统的一次新革命电动转向系统。

电动转向系统符合现代汽车机电一体化的设计思路，该系统由转向传感器装置、车速传感器、助力机械装置、提供转向助力机及微电脑控制单元组成。

该系统工作时，转向传感器检测到转向轴上转动力矩和转向盘位置两个信号，与车速传感器测得的车速信号一起不断地输入微电脑控制单元，该控制单元通过数据分析以决定转向方向和所需的最佳助力值，然后发出相应的指令给控制器，从而驱动电机，通过助力装置实现汽车的转向。

通过精确的控制算法，可任意改变电机的转矩大小，使传动机构获得所需的任意助力值。

2、电动转向系统的特点液压助力转向系统已发展了半个多世纪，其技术已相当成熟。

但随着汽车微电子技术的发展，对汽车节能性和环保性要求不断提高，该系统存在的耗能、对环境可能造成的污染等固有不足已越来越明显，不能完全满足时代发展的要求。

电动转向系统将最新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、减少环境的污染等。

一、起动前准备：1.试验电机转向是否正确，从电机顶部往泵看为顺时针旋转，试验时间要短以免使机械密封干磨损。

2.打开排气阀使液体充满整个泵体，待满后关闭排气阀。

3.检查各部位是否正常。

4.用手盘动泵以使润滑液体进入机械密封端面。

5.高温型应先运行预热，升温速度50。

C/小时，以保证各部受热均匀。

二、起动：1.全开进口阀门。

2.关闭吐出管路阀门。

3.起动电机，观察泵运行是否正确。

4.调节出口阀开度以所需工况，如用户在泵出口处装有流量表或压力表，应通过调节出口阀门开度使泵在性能参数表所列的额定点上运转，如用户在泵出口处没有装流量表或压力表时，应通过调节出口阀门开度；测量泵的电机电流，使电机在额定电流内运行，否则将造成泵超负荷运行（即大电流运行，至使电机烧坏）调正好的出口阀门开启大与小和管路工况有关。

5.检查轴封泄漏情况，正常时机械密封泄漏应小于3滴/分。

6.检查电机，轴承处温升≤70。
