摘　　要：液压转向系统性能方面提升的难点主要是转向回正性能,某车型在开发阶段出现低速转向回正差的问题,通过对各影响因素进行详细的故障树分析,对影响转向回正的整车参数和关键部件特性进行识别,初步理清了前独立悬架车型转向回正提升工作开展的思路和方向,控制悬架、转向系统零部件关键性能,减小回正阻力矩提升了整车低速回正性能,为后期解决类似问题提供参考依据。The main difficulty of hydraulic steering system performance is the steering return performance,in thedeyelopment stage of a vehicle,the problem of steering return difference at low speed,based on the detailed analysis of thefault tree,the identification of the vehicle parameters and key components affecting the steering return,preliminary clarifythe thinking and direction of the development of the front independent suspension steering,control the key performance ofsuspension and steering system components,reducing the moment of resistance improves the performance of vehicle,toprovide a reference for solving similar problems.

关 键 词：回正性能 关键部件特性 回正阻力矩
