要
转向系统是汽车底盘的重要组成部分， 转向系统性能的好坏直接影响到汽车行驶的 安全性、操纵稳定性和驾驶舒适性，它对于确保车辆的行驶安全、减少交通事故以及保 护驾驶员的人身安全、改善驾驶员的工作条件起着重要作用, 因此，开发一种科学、 先 进、稳定、环保的汽车转向系统，不但可以满足人们的驾驶需求同样也会在激烈的时常 竞争中提升自己的竞争能力。 本设计的目的就是综合现今国内、 国际上转向系统的发展情况探讨开发一种更加先 进、科学的转向系统，并在转向器方面做重点的讨论，本文介绍了汽车转向器的类型、 结构，以及转向器综合性能评价的发展趋势，在对大量资料分析的基础上，提出了转向 系的总体方案，并针对转向器的参数进行了分析和计算，根据汽车动力转向系的设计要 求，以及机械设计原理、汽车设计基础设计了液压动力转向器的总体结构。该课题的研 究会为汽车转向系统的设计和开发提供更加科学、环保、稳定、高效的方法，对提高产 品设计和制造质量探索了新的途径。

ABSTRACT
Automotive steering system is an important part of the chassis, steering system performance to a direct impact on car safety, handling stability and driving comfort, it is essential to ensure the vehicle safety and reduce traffic accidents and the protection of the driver's personal safety, to improve the working conditions of the driver plays an important role, therefore, to develop a scientific, advanced, stable, environmentally friendly vehicle steering systems, not only to meet the needs of people driving would also from time to time in the fierce competition to upgrade their competitiveness. The purpose of this design is the integrated current domestic and international on the development of steering systems to explore the development of a more advanced and scientific steering system and steering the focus of the discussion has done, this article describes the types of vehicle steering gear, structure, and steering the development of a comprehensive performance evaluation of the trend in the analysis of large amounts of data on the basis of a steering system of the overall program, and steering parameters for the analysis and calculation, according to the vehicle's power steering system design requirements, as well as the mechanical design principle, the basis for the design of automotive design the hydraulic power steering of the overall structure. The study of the subject motor vehicle steering system for the design and development of more scientific, environmental protection, stable and efficient method to improve the quality of product design and manufacture of new avenues to explore.
