Title  The design of a car brake system and its major

components                                    

Abstract

Nowadays, the car has entered the homes, and it has been the indispensable transportation we need for traveling. This makes higher requests for cars on controllability, driving comfort, etc. So brake system which keeps driving safely should be taken into account in the first place. At first, this paper analyzes the vehicle parameters, and chooses the appropriate form of brakes, brake drive mechanism and braking pipeline system with national standards and industry standards according to its parameters. Then I analyzed and computed the braking force distribution coefficient and of the braking system. Finally I determined the structural parameters of the main components of brake. After proofreading and calculation, this design meet the national standards and industry standards. This paper also gives the design of major parts of the brake system with CAD 3D models, including parts drawing of components and final assembly drawing.
