Abstract
With the development of science and technology, the means of transportation have changed a lot in human life. In recent years, due to the rapid improvement of the national economic level cars are becoming more and more popular. After the pursuit of convenient car travel, people began to pursue the quality of other performance of the car, the premium car introduced into the market, and by the majority of people welcome and love. The braking performance of automobile is one of the most important performances in the process of driving. A car with a good braking system can further ensure the safety of life in an emergency, therefore, the design of the car braking system and the current social concerns linked to the issue has a very practical significance.
This braking system design takes AUDI A6L as the reference model, after referring to the national requirements and industry standards. The design meets the requirements of the braking system

In this design, first according to the actual model, check out the basic parameters of the car, determine the basic mechanism of the car brake system and design scheme. After the basic scheme is determined, the size of important parts such as brake disc and main cylinder is designed and calculated, and the mechanical analysis is carried out. After the design is completed, the three-dimensional structure diagram and two-dimensional dimension diagram are drawn by computer technology, and then the finite element analysis software is used to analyze whether the model structure is reasonable. In the design process, practical factors such as simple structure, low cost and reliable work should be taken into account. The final result shows that the designed braking system meets the requirements and is a feasible design scheme.
