比亚迪F3轿车制动系统设计 摘要: 关键词： The Design Of Braking System Of The BYD F3 car Type Of Car Abstract In recent years, the development of chinese automobile industry is very rapid, the car retains the quantity also increases continuously, the attendant is the high accident rate, therefore the safety of cars has become more important for the automotive industry development , and the automobile brake system is the most important guarantee driving safety. The paper introduces the BYD F3 car brake system design exploration. First introduce the automobile brake system design significance, development situation, structure, classification, and then to the braking system demonstration program and choice, including brake type scheme analysis, brake drive mechanism of the organization form selection, hydraulic shunting system form selection and hydraulic brake master cylinder design, the final determination by double circuit hydraulic front disc and rear drum brakes. In addition, also known under automobile related parameters, obtained by calculating the main parameters before and after the brake, braking torque distribution coefficient, braking torque and braking force and the hydraulic brake drive mechanism parameters. The braking performance is analyzed in detail. Keywords： the automobile brake system，brake，the brake pipe layout form 目 录 1 绪论 1 1.1 选题的背景及意义 1 1.2 制动系统发展及研究现状 1 1.3 国内制动器设计理论概况 2 2 制动系统方案论证分析与选择 2 2.1 制动器形式方案分析 2 2.1.1 鼓式制动器 2 2.1.2 盘式制动器 5 2.2 制动驱动机构的结构形式选择 6 2.2.1 人力制动系 6 2.2.2 伺服制动系 6 2.2.3 动力制动系 6 2.3 液压分路系统的形式的选择 7 2.3.1 II型回路 8 2.3.2 X型回路 8 2.3.3 其他类型回路 8 2.4 液压制动主缸的设计方案 8 3 制动系统设计计算 10 3.1 制动系统主要参数数值 10 3.1.1 相关主要技术参数 10 3.1.2同步附着系数的分析 10 3.2制动器有关计算 11 3.2.1确定前后轴制动力矩分配系数β 11 3.2.2制动器制动力矩的确定 11 3.2.3后轮鼓式制动器的结构参数与摩擦系数的选取 12 3.3制动器制动因数计算 14 3.3.1前轮盘式制动效能因数 14 3.3.2后轮鼓式制动器效能因数 14 3.4 制动系统结构设计 14 3.4.1前制动器 15 3.4.2后制动器 15 3.4.3制动管路 17 3.4.4 制动主缸 17 3.5 制动器主要零部件的材料设计 18 3.5.1 制动盘 18 3.5.2 制动钳 19 3.5.3 制动块 19 3.5.4 摩擦材料 19 3.5.5 制动鼓 19 3.5.6 制动蹄 20 3.5.7
