摘 要：在汽車的行駛方面，它的制動系統(tǒng)會對汽車的安全可靠造成很大影響。由于道路的不斷提速，車輛速度不斷增大還有在路上車流量的逐步增長，汽車的制動系統(tǒng)對于汽車的安全性與可靠性有著極大的作用。汽車要是想要更好的變現(xiàn)出它優(yōu)良的動力性能，就必須要保證它要有好的制動性能和可靠的制動系的工作。
盤式制動器還有另外一個名字叫做碟式制動器，它的構(gòu)造簡單、重量較輕、散熱較快、便于調(diào)整，這是這種制動器的優(yōu)勢，在高負(fù)載的過程中對于它耐高溫的性能表現(xiàn)的尤為突出，同樣，它所取得的制動效果也是非常穩(wěn)定的，在道路不平或者是在冬季行車，在短時間內(nèi)盤式制動更容易停車。這次的設(shè)計主要是對汽車制動器的功能設(shè)計做要求，配分它的制動力，分析它的結(jié)構(gòu)方案，選擇制動器的重要零件以及選擇最主要的參數(shù)，進(jìn)行制動器相關(guān)的各種參數(shù)計算，同時分析裝配好的尺寸鏈。在設(shè)計的過程中會涉及許多因素，如選擇同步系數(shù)，計算制動力矩和選擇制動器的主要元件等。在制動器設(shè)計的一般原則下，要總體的對制動效能進(jìn)行充分的思考，還有制動效果是否穩(wěn)定，調(diào)整制動的間隙是否簡便，制動器的大小，重量以及噪音等各種成分來設(shè)計這個產(chǎn)品。

title Design of the braking system of disk brakes



Abstract
Automotive vehicle brake system directly affects the driving safety and parking reliability. With the rapid development of highway and the increased speed limit as well as the increasing traffic density in order to ensure driving and parking safety the reliability of automotive brake systems has become increasingly important. Only excellent reliable car braking system can fully play its role of adjusting the car’s dynamic performance.
Disc brake also known as dish brakes it brakes and ventilates fast and is also light weight. Its simple structure easy clearance adjustment outstanding performance at high temperature with heavy load better working stability enables it to stop the car quicker than traditional drum brakes at winter and bad road conditions.
The function and design requirement of the vehicle brake system analysis of the construction scheme distribution of braking torque selection of the main components as well as the main coefficient calculation of the system are all concluded in this paper. based on the primary principle of brake designing taking the efficiency stability and easy clearance adjustment as well as the size quality and noise making into consideration this paper covers many aspects while designing.
