双前桥汽车转向回正性能的分析与改进

Steering Returnability Analysis and Improvement of Double-Front-Axle Vehicles

以双前桥载货车为研究对象,介绍了影响转向回正性的主要因素,修订了转向回正性能的试验评价方法,系统地概述了故障分析流程,针对试验样车回正性差的问题,通过降低样车转向系统机械阻力,提升助力系统液压响应等措施,有效地改善了车辆的转向回正性能,为解决同类问题提供了参考。

Taking double-front-axle truck as research object,this paper introduces the main influence factors of returnability,revises the test evaluation method,summarizes the analysis flow of fault.To solve the problem of bad returnability,by reducing the mechanical resistance of the steering system and improving the hydraulic response of the assist system,the returnability can be effectively improved,which provides a reference of solving similar problems.
