摘要
目前,传统燃油动力的轻卡普遍采用的是循环球液压助力转向系统,该转向系统的缺点很明显,转向杆系相对较复杂,自由间隙相对线性转向系统更难控制。为提高轻卡的舒适性和安全性,提升轻卡的智能化水平,文章以新能源电动汽车智能电动转向系统为研究对象,创造性地设计了转向系统内循环反向机构,提高了系统的定位精度与稳定性,增加了能传递的最大扭矩,实现了转向的自动找正;利用有限元分析软件ALTAIR Hypermesh对所设计的电动助力转向系统进行模态分析,得出固有频率、应力分布等参数特性,实现结构工艺的优化设计。文章所设计的智能电动转向系统性能优异,实用性强,为电动助力转向系统的发展提供一种方案,也为轻卡的智能化驾驶打下基础。
At present,the traditional fuel-powered light card is generally used in the circulation ball hydraulic power steering system,the disadvantages of the steering system is obvious,the steering rod system is relatively complex,free clearance is relatively difficult to control than linear steering system.In order to improve the comfort and safety of the light card,improve the intelligent level of the light card,take the intelligent electric steering system of the new energy electric vehicle as the research object,the innovative design of the cycle reverse mechanism in the steering system,improve the positioning accuracy and stability of the system,increase the maximum torque that can be transmitted,realize the automatic correction of the steering;Realize the optimal design of structural process.The intelligent electric steering system developed is excellent in performance and practical,which provides a scheme for the development of electric power steering system and lays the foundation for the intelligent driving of light card.
