编号 潍 坊 学 院 毕 业 设 计 技 术 报 告 课题名称：汽车转向系统的三维设计 及仿真分析 学生姓名： 刘鹏 学 号： 11011240119 专 业： 车辆工程 班 级： 一班 指导教师： 郭姗姗 2015年 5 月 摘要 本课题的题目是转向系的设计轮轴旋转，转向齿轮轴与转向齿条啮合，从而促使转向齿条直线运动，实现转向。实现了转向器结构简单紧凑，轴向尺寸短，且零件数目少的优点又能增加助力，从而实现了汽车转向的稳定性和灵敏性。在本文中主要进行了转向器齿轮齿条的设计和对转向齿轮轴的校核，主要方法和理论采用汽车设计的经验参数和大学所学机械设计的课程内容进行设计，其结果满足强度要求，安全可靠。 : 电动助力转向助力特性控制策略The car in the process often requires a change of the direction and called to the car through. Wheel type turns to wheel (is generally front wheel) vertical axis of the car sheered to be implemented. A control is used to change or return the car in the private sector is called the car turned the system. Commonly used system for the car turned into a power steering system and power steering system two categories. Have power steering system also referred to the system is based on mechanical mans strength is, of all of force is a mechanical device, is to control and turned to the organization of three parts of the car turned is an important component system, the performance of the direct impact on the road safety and reliability. The system power steering power steering (Power Steering System) the system also called to boost, in turn to the department of machinery on the basis of an auxiliary steering apparatus is boost of the system. The car to the electric power steering systems of traditional hydraulic power to the system cannot compare with is the power to the inevitable trend of development. Electric power steering adopts a direct offer help, help the size of the unit (electronic control unit) control. It can save energy and enhanced security, and the environmental protection, is a stick to the development of modern technology. Key words: Electric power steering help feature control strategy  目录 摘要 I ABSTRACT II 第1章 汽车转向系统总述 1 1.1 转向系统的发展历史 1 1.2 转向系统的分类及组成 3 1.3转向系统的发展趋势 6 1.4 转向系统的设计要求 6 第2章转向系统介绍
