Abstract
For any car, the braking system is undoubtedly one of the important safeguards of its safety. So the design of the brake system is particularly important and critical. The design of the main contents include the design and purpose of the brake system, the basic introduction of the brake system, the design of the brake calculation, brake drive design and calculation of brake performance analysis. The basic idea of this design is through the understanding of the Dongfeng warrior EQ2050B car some known parameters, such as quality parameters, size parameters and through the parameters, select the basic parameters of the brake, the initial formulation of technical solutions related to the calculation, through continuous improvement , To complete the design of the braking system. I have not only considered the matching design between braking system and vehicle, but also have considered the car's kinematics, thermodynamics and the other issues. When a car is in the process of driving, if the car's braking system can work properly, the safety of the car can be guaranteed, the car will be able to better play its power.
