Title The matching design of a type of automobile brake system
Abstract
With the rapid development of automobile industry and highways, the significant of car ownership growth,generated traffic safety issues also lead to further attention of automobile manufacturers and consumers.The automobile braking reliability directly affects the car occupants' safety.The reliability of the brake system is closely related to the relationship of the driving safety.This paper is based on the reference and the analysis of the existing automobile brake technology and research braking system design, from the design requirements, analysis of scheme selection and relevant parts of the design calculation aspects combined with the actual design of a certain type of car braking system to illustrate the design process. Finally, a design method is proposed.Including the selection and design of brake type, selection of the brake hydraulic circuit form,selection of brake master cylinder , determine the synchronous adhesion coefficient, finally discusses the method of braking performance evaluation analysis and checking etc..
