1. 研究目的与意义（文献综述）

the purpose and significance of design

with the development of transportation system, the proportion of cars in daily transportation is increasing, and the dependence on cars is also increasing. in pursuit of speed, car safety is also an important measure index, car manufacturers and users have put more attention to the car braking performance. the main function of the car brake system is to reduce the speed of the car in motion or even stop, keep the car speed stable in downhill driving, and make the car stop moving. in the complex traffic situation, the brake system as the speed control system of car, its performance is directly related to the strength of car speed control ability, is directly related to the life safety of car drivers. at the same time, improving and improving the braking performance of cars has always been an important task for car manufacturers. therefore, by improving and improving the performance of car brake, the safety of car in the process of driving can be improved, and the probability of accidents in high-speed transportation and complex traffic conditions can be reduced.

2. 研究的基本内容与方案

the purpose of this study is to learn and master the requirements of brake design by integrating the knowledge that has been learned and reading the relevant periodical literature at the same time. by using the knowledge of automobile design, this paper designs the disc brake assembly, and learns to use solidworks, autocad, catia and other software to establish the three-dimensional model of the brake, analyzes the brake, and puts forward the possible optimization scheme, so that the design results can achieve satisfactory results.
