制動(dòng)器畢業(yè)設(shè)計(jì)

摘 要
國(guó)內(nèi)汽車市場(chǎng)迅速發(fā)展，而轎車是汽車發(fā)展的方向。然而隨著汽車保有量的增加，帶來的安全問題也越來越引起人們的注意，而制動(dòng)系統(tǒng)則是汽車主動(dòng)安全的重要系統(tǒng)之一。因此，如何開發(fā)出高性能的制動(dòng)系統(tǒng)，為安全行駛提供保障是我們要解決的主要問題。另外，隨著汽車市場(chǎng)競(jìng)爭(zhēng)的加劇，如何縮短產(chǎn)品開發(fā)周期、提高設(shè)計(jì)效率，降低成本等，提高產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力，已經(jīng)成為企業(yè)成功的關(guān)鍵。
本說明書主要介紹了santana2000轎車制動(dòng)系統(tǒng)的設(shè)計(jì)。首先介紹了汽車制動(dòng)系統(tǒng)的發(fā)展、結(jié)構(gòu)、分類，并通過對(duì)鼓式制動(dòng)器和盤式制動(dòng)器的結(jié)構(gòu)及優(yōu)缺點(diǎn)進(jìn)行分析。最終確定方案采用液壓雙回路前盤后鼓式制動(dòng)器。除此之外，它還介紹了前后制動(dòng)器、制動(dòng)主缸的設(shè)計(jì)計(jì)算，主要部件的參數(shù)選擇及制動(dòng)管路布置形式等的設(shè)計(jì)過程。

Abstract
The rapid development of the domestic vehicle market, saloon car is an important tendency of vehicle. However, with increasing of vehicle, security issues are arising from increasingly attracting attention, the braking system is one of important system of active safety. Therefore, how to design a high-performance braking system, to provide protection for safe driving is the main problem we must solve. In addition, with increasing competition of vehicle market, how to shorten the product development cycle, to improve design efficiency and to lower costs, to improve the market competitiveness of products, and has become a key to success of enterprises.
This paper mainly introduces the design of braking system of the santana2000 type of car. Fist of all, braking system’s development, structure and category are shown, and according to the structures, virtues and weakness of drum brake and disc brake, analysis is done. At last, the plan adopting hydroid two-backway brake with front disc and rear drum. Besides, this paper also introduces the designing process of front brake and rear brake, braking cylinder, parameter’s choice of main components braking and channel settings.
Key words: braking; brake drum; brake disc; hydroid pressure
