某高端轻卡转向回正性差原因分析及改进

A high-end light truck turning back is poor root cause annlysis and improvement

汽车的转向回正性是指在遭遇外界干扰时,汽车能抵抗干扰而保持直线、稳定行驶的能力。汽车的转向回正性不仅影响汽车驾驶的操纵方便程度,而且也是决定高速汽车安全行驶的一个重要性能。文章通过与同类标杆车型对比对回正性能影响因素进行系统分析,最终通过减小转向阻力来提升该轻卡转向回正性能。

Automotive steering back positive refers to the encounter interference, car can resist interference and maintain ability of straight line driving stability. Automotive steering back positive affects not only the driving control convenience, but also decide the car safety is an important performance.In this paper, compared with the similar models benchmarking system analysis the factors which influence the performance of return-to-center, ultimately through to reduce the resistance to improve the high-end light trucck steering return-to-center performance.
