摘要
當今，隨著高速公路路網(wǎng)的不斷發(fā)展，汽車車速得提高以及車流密度的增大，對汽車制動系統(tǒng)的工作可靠性要求日益重要，制動器則是制動系統(tǒng)的執(zhí)行機構(gòu)，其性能好壞直接影響汽車的安全。因此如何開發(fā)出高性能的制動系統(tǒng)，為安全行駛提供保障是我們要解決的主要問題。此外，隨著汽車市場競爭的加劇，如何縮短產(chǎn)品開發(fā)周期、提高設(shè)計效率，降低成本等，提高產(chǎn)品的市場競爭力，已成為企業(yè)成功的關(guān)鍵。
本文主要根據(jù)已有的CA1041車輛的數(shù)據(jù)對制動系統(tǒng)的前盤式制動器及制動管路進行設(shè)計。首先介紹了汽車制動系統(tǒng)的發(fā)展、結(jié)構(gòu)、分類，并通過對鼓式制動器和盤式制動器的結(jié)構(gòu)和優(yōu)缺點進行分析。最終確定選用通風浮動盤式制動器。除此之外，還介紹了前后制動器、制動主缸的設(shè)計計算，主要部件的參數(shù)選擇及制動管路布置形式等的設(shè)計過程。

ABSTRACT
It is to carry on the transformation to design to originally design to the car rear wheel drum type brake, the transformation is Elysee car, repack its drum type brake into the a type of floating brake.
Nowadays, with the constant development of the highway network at a high speed, the car speed must be improved and the increase of the density of rate of traffic flow, the working dependability to car brakes is required increasingly importantly, the brake is the executive body of brakes, its quality of performance influences the security of the car directly. The a type brake is regarded as the substitute products of the drum type brake, of simple structure, quality little, hot stability fine, react sensitive, and apt to get rid of muddy water filth,etc. with the aid of centrifugal function of brake disc, it is convenient too to maintain.
This text introductory song expound records of type advantage of brake, introduce hydraulic pressure and atmospheric pressure records of type structure and operation principle of brake respectively. And to records of type brake brake disc designed, design to apply the brake pincers,etc., school and method have explained. And then and design the brake to make power and meet the demands in Institute of Computing Technology. Carried on the analysis of finite element to the brake disc finally.
Keyword: A type brake; Apply the brake to restrain; Make motive force
