摘　　要：在当前的车辆开发中,传统的燃油车、电动车的都已实现了转向系统的电动助力,但转向系统增加了蜗轮蜗杆结构,并且电机进行助力驱动,这导致在蜗轮蜗杆以及与电机配合结构、尺寸、公差的影响,导致转向系统在过一些特殊路况下产生转向异响。文章介绍了EPS转向系统在过鹅卵石、绳索路等特殊路况是转向系统易产生异响,通过对空载力矩、蜗轮蜗杆的配合以及电机与蜗杆的配合型式对转向系统特殊路况异响。In the current vehicle development,the traditional fuel vehicles and electric vehicles have realized the electric power assist of the steering system,but the steering system increases the worm gear and worm structure,and the motor is driven by the power assist,which leads to the influence of the worm gear and worm and the structure,size and tolerance of the motor fit,resulting in the steering system producing steering noise under some special road conditions.This paper introduces the EPS steering system in special road conditions such as cobblestones,rope roads,etc.,the steering system is prone to abnormal noise,through the no-load torque,worm gear and worm cooperation and the motor and worm coordination type of the steering system to the special road conditions abnormal noise.
