摘要在汽车速度不断提高的情况下，汽车安全问题已成为备受关注的问题。汽车盘式制动器和ABS防抱死系统是汽车行车安全的重要保障之一。
本文先确定了盘式制动器结构的选择方案，然后简述了ABS防抱死制动系统，并对其主要组成部分轮速传感器做了一个简要的介绍。
设计主体部分是设计盘式制动器并对其进行优化设计。根据相关设计资料，再选定相关参数并进行计算，确定各零件的主要尺寸参数。计算了制动器的制动力矩并对制动力矩进行校核。之后又对摩擦衬块的磨损特性进行了计算，校核摩擦衬块的磨损程度。对制动器的间隙做出了选择并提出了调整制动器间隙的方法。86040
然后运用Pro/Engineer进行主要零件三维建模，再运用ANSYS workbench对制动盘、制动块、制动钳体和制动钳支架进行有限元分析并根据分析结果找出各零件相对薄弱的地方，对它们进行了优化设计。对优化设计后的各零件再次有限元分析，验证了优化设计过后的零件均符合要求。最后使用AutoCAD绘制了制动器的主要零件图和带有ABS的第三代轮毂轴承单元的盘式制动器装配图。

Abstract In the case of continuously improving the speed of the car, the car safety problem has become a concern。 Automobile brake and ABS anti lock braking system is an important guarantee for safe driving。
This paper firstly introduces the ABS system classification, the basic structure and the working principle。 Next, the different types of disc brake are introduced, and the advantages and disadvantages are compared, and the scheme of disc brake is determined。
The main part of the design is the design of the disc brake and its optimization design。 According to the relevant design information, selecting the relevant parameters and calculating,is to determine the main dimension parameters of the parts。 The braking torque of the brake is calculated and the braking torque is checked。 Then the wear characteristics of the friction lining were calculated, and the wear degree of the friction lining was checked。 The gap between the brake is selected and the method of adjusting the clearance of the brake is put forward。
Then I use ProE to carry on the three-dimensional modeling of the main parts, and use the workbench ANSYS to analyze the brake disc, brake block, brake caliper and brake caliper bracket。And the design is optimized according to the analysis results。 Finally the AutoCAD is used to draw the parts of the brake and the disc brake assembly with wheel speed sensor and wheel speed sensor probe。
