摘 要
隨著社會(huì)的飛速發(fā)展，科技越來越發(fā)達(dá)，世界也變得越來越小了，造成這個(gè)現(xiàn)象的基本原因就是交通工具的發(fā)展和普及，尤其是汽車的應(yīng)用，靈活高速的汽車給我們的生活帶來了極大便利。一方面，轎車變的越來越重、動(dòng)力越來越大；另一方面，人們越來越強(qiáng)調(diào)汽車駕乘的舒適性和安全性。因而，作為能保證汽車安全行駛的組成部分之一—制動(dòng)系，有必要對它的組成構(gòu)件進(jìn)行設(shè)計(jì)計(jì)算。
本文系統(tǒng)詳細(xì)的介紹了汽車制動(dòng)系的結(jié)構(gòu)型式及其主要構(gòu)件的設(shè)計(jì)計(jì)算，闡述了制動(dòng)器的兩種結(jié)構(gòu)型式的選擇和各自的工作原理、制動(dòng)系的主要參數(shù)及其選擇、制動(dòng)器主要零部件的結(jié)構(gòu)設(shè)計(jì)和分析計(jì)算、制動(dòng)驅(qū)動(dòng)結(jié)構(gòu)的結(jié)構(gòu)型式選擇與設(shè)計(jì)計(jì)算。并且通過以上的比較分析，在經(jīng)濟(jì)可靠的基礎(chǔ)上選擇歸納了伊蘭特轎車制動(dòng)系主要構(gòu)件的結(jié)構(gòu)與參數(shù)，予以最為合理的配置。其中重點(diǎn)介紹了汽車車制動(dòng)系的主要構(gòu)件——浮鉗盤式制動(dòng)器、液壓雙回路制動(dòng)主缸的分析計(jì)算。

ABSTRACT
As the society is making great progress, scientific technology becomes more and more developed, and the world becomes smaller and smaller. The basic cause of this is the development and popularization of transportations, especially the application of automobiles, which bring great convenience to our lives. On one hand, what the car changes is heavier and heavier, motive force is greater and greater; On the other hand, people emphasize comfortableness and security that the automobile drives more and more. Therefore, as guaranteeing one of the components that the automobile goes safely--the brake system, it is necessary to carry on exhaustive designing calculation .
This text mainly introduces the structure pattern of the brake system and its designing calculation of main departments, and explains two kinds of structure patterns and choosing and one's own operation principle of the brake , main parameter of the brake system in the department and choosing, structural design and calculation of the main spare part of the brake , applying the brake urges the structure pattern of the structure to choose and design and calculate , makes the regulation device that power distributes. Through comparative analysis of the above , is it sum up Elantra apply the brake structure and parameter , department of main member to choose on the basis of the thing that economy is reliable , in order to reach and dispose best. Especially, it introduces the main member of the department of the brake system among them --Float pincers records of type brake , hydraulic pressure pairs of meeting way apply the brake analysis of master cylinder calculate with anti-lock braking system , urge slip resistance systematic theory analyse. And have checked to rubing the friction characteristic lined with slice at the end of the thesis.
