With the rapid development of highway and the speed increased, and the increasing traffic density, CP, in order to ensure traffic safety, parking and reliable, the reliability of automotive brake systems become increasingly important. Only brake good, reliable car brake system in order to give full play to its dynamic performance. Disc brake, also known as disc brakes, which brake cooling fast, light weight, simple structure, easy adjustment, especially when the high temperature performance and high load, the braking effect of stability, but not afraid of mud invasion, and poor road conditions in winter Under the road, disc brake drum brake more easily than in a short period of time so that the car stopped. Some disc brake disk brake also opened a lot of holes to speed up ventilation, to improve braking efficiency. The general principles of the brake design, considering the braking performance, brake performance stability, ease of adjustment of brake clearance, the brake noise, the size and quality and design of this product and other factors. Synchronization involved in the design of the selection coefficient, selection of brake performance factors, the calculation of braking torque, and the main components of the brake selected for the final check on the calculation of brake design. Keywords: disc brake, brake system, synchronization coefficient 目 錄 摘要 I ABSTRACT II 目 錄 III 第1章 緒論 1 1.1 引言 1 1.2 設(shè)計任務(wù) 3 1.3 制動器的發(fā)展過程 3 第2章 制動器的結(jié)構(gòu)形式及選擇 4 2.1 盤式制動器的結(jié)構(gòu)形式及選擇 4 2.1.1固定鉗式盤式制動器 5 2.1.2浮動鉗式盤式制動器 5 2.2 制動盤的分類及選擇 6 2.3 奧迪A8型轎車盤式制動器的結(jié)構(gòu)與工作原理 7 第3章 制動器的主要參數(shù)及其選擇 9 3.1 制動力與制動力分配系數(shù) 9 3.2 同步附著系數(shù) 15 3.3 制動強度和附著系數(shù)利用率 16 3.4 制動器最大制動力矩 18 3.5 利用附著系數(shù)與制動效率 20 3.6 制動器因數(shù) 22 3.7 盤式制動器主要參數(shù)與摩擦系數(shù)的確定 23 第4章 制動器的設(shè)計計算 25 4.1 摩擦襯塊的磨損特性計算 25 4.2 制動器熱容量和溫升的核算 27 4.3 盤式制動器制動力矩計算 28 第5章 制動器主要部件的結(jié)構(gòu)設(shè)計與計算 31 5.1 制動盤 31 5.2 制動鉗 31 5.3 制動塊 32 5.4 襯塊警報裝置設(shè)計 32 5.5 摩擦材料 32 5.6 制動器間隙 33 5.7 緊固摩擦片鉚釘?shù)募羟袘?yīng)力驗算 33 第6章 制動驅(qū)動機構(gòu)的型式選擇與設(shè)計計算 35 6.1 伺服制動器的結(jié)構(gòu)形式選擇 35 6.2 制動管路的多回路系統(tǒng) 36 結(jié)論 38 致謝 39 參考文獻 40 附錄1 41 附錄2 43 -4-
