【正文】 developing quickly, however, with the increase of the auto possession, bring security is more and more attention, and brake system is the important car active safety system one. The brake is a moving car slow down or stop, make the downhill cars speed stability and make already in place of the car they offend (including in slope) stay fixed institution. With the rapid development of the highway speed and the improvement of traffic density and increases day by day, in order to guarantee safety, car brake system reliability of work appear increasingly important. Also only brake performance is good, brake system reliable car and fully play its dynamic performance this manual mainly introduces the design of the car brake system flying across. First this paper reviewed the automobile braking system structure, classification, and through to the drum brake disc brake and the structure and the advantages and disadvantages are analyzed. Ultimately determine the scheme adopts hydraulic double circuit with disk and drum brake system.Key words: brake、disk brake 、drum brake、 design parameters、 braking performance、目 錄1 緒論...........................................................................................................................1 制動系統(tǒng)概述................................................................................................1 制動系的作用及其組成...................................................................1 制動系一般工作原理.......................................................................1 制動系的類型...................................................................................2 制動系的設(shè)計要求...........................................................................3 制動系統(tǒng)研究現(xiàn)狀及發(fā)展趨勢....................................................................62 制動系統(tǒng)方案論證分析與選擇...............................................................................8 制動器結(jié)構(gòu)型式及選擇................................................................................8 盤式制動器.......................................................................................8 鼓式制動器......................................................................................10 制動驅(qū)動型式選擇.......................................................................................14 簡單制動系..................................................................................... 14 動力制動系......................................................................................15 伺服制動系......................................................................................15 制動主缸型式...............................................................................................16 制動管路型式選擇........................................................................................17 II型回路...........................................................................................18 X型回路...........................................................................................18 其他類型回路...................................................................................18 制動系統(tǒng)布置型式.........................................................................................193 制動系統(tǒng)主要參數(shù)及其設(shè)計計算............................................................................20 參考車型制動系相關(guān)主要參數(shù)數(shù)值.............................................................20 同步附著系數(shù)分析.........................................................................................20 制動力及制動力分配系數(shù)..............................................................................21 制動強(qiáng)度和附著系數(shù)利用率..........................................................................24 制動器制動力及制動力矩的計算..................................................................25 制動因數(shù)...........................................................................................................26 前輪盤式制動器參數(shù)設(shè)計計算........................................................................27 后輪鼓式制動器參數(shù)設(shè)計計算........................................................................28 制動器磨損特性熱容量及溫升計算................................................................294 制動器主要零部件的結(jié)構(gòu)設(shè)計...................................................................................32 盤式制動器主要零部件的結(jié)構(gòu)設(shè)計................................................................34 制動盤...................................................................................................34 制動鉗...................................................................................................34 制動塊...................................................................................................35 摩擦材料...............................................................................................35 鼓式制動器主要零部件的結(jié)構(gòu)設(shè)計................................................................35 制動鼓...................................................................................................35 制動蹄...................................................................................................36 制動底板...............................................................................................36 制動蹄的支承.......................................................................................37 制動輪缸...............................................................................................37 5 液壓制動驅(qū)動機(jī)構(gòu)的設(shè)計計算.................................................................................38 前輪盤式制動輪缸直徑與工作容積設(shè)計計算................................................38 后輪鼓式制動輪缸直徑與工作容積設(shè)計計算................................................39 制動主缸與工作容積設(shè)計計算........................................................................40 制動踏板力與踏板行程...........................
