摘要：随着汽车的普及，对于汽车的各项性能指标和操纵感受也更加重视。而转向系统和转向桥工作环境复杂多变，其关系着整车的安全性和操纵性，因此对转向系统和车桥的设计提出了更高的要求。
本论文对转向系统与前桥的工作性能方面进行设计。秉着兼顾安全性、舒适性、稳定性、经济性及减轻质量的原则对转向系统和前桥的现状、结构、分类和工作原理进行了深入的对比分析，从而选出最优方案进行设计；对结构进行强度校核以达到可靠性良好的目的；对重要部件的参数进行优化，使之更接近理论期望值。

Abstract：We pay more attention to each performance index and manipulate feelings for
cars with the popularity of cars.The complexity of working environment of front axle and steering system is related with the safety and maneuverability.So weshouldmention higher requirements forthe design of steering system and frontaxle.
Thethesis is about the design of the performance aspect of the front axle and steering syst
em.Taking consideration of safety, comfort, stability, economy and lightweight,it analyses thoroughlymany aspects of the steering system and front axle,including present situation,structure, classification and working principle.So the best program is gotten.checking the strength of constructureis to get good reliability;For making it more close to the theoretical expectations, it is necessary to Optimize the parameters of the important parts.
