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(jì)任務(wù) 3 1.3 制動(dòng)器的發(fā)展過程 3 第2章 制動(dòng)器的結(jié)構(gòu)形式及選擇 4 2.1 盤式制動(dòng)器的結(jié)構(gòu)形式及選擇 4 2.1.1固定鉗式盤式制動(dòng)器 5 2.1.2浮動(dòng)鉗式盤式制動(dòng)器 5 2.2 制動(dòng)盤的分類及選擇 6 2.3 奧迪A8型轎車盤式制動(dòng)器的結(jié)構(gòu)與工作原理 7 第3章 制動(dòng)器的主要參數(shù)及其選擇 9 3.1 制動(dòng)力與制動(dòng)力分配系數(shù) 9 3.2 同步附著系數(shù) 15 3.3 制動(dòng)強(qiáng)度和附著系數(shù)利用率 16 3.4 制動(dòng)器最大制動(dòng)力矩 18 3.5 利用附著系數(shù)與制動(dòng)效率 20 3.6 制動(dòng)器因數(shù) 22 3.7 盤式制動(dòng)器主要參數(shù)與摩擦系數(shù)的確定 23 第4章 制動(dòng)器的設(shè)計(jì)計(jì)算 25 4.1 摩擦襯塊的磨損特性計(jì)算 25 4.2 制動(dòng)器熱容量和溫升的核算 27 4.3 盤式制動(dòng)器制動(dòng)力矩計(jì)算 28 第5章 制動(dòng)器主要部件的結(jié)構(gòu)設(shè)計(jì)與計(jì)算 31 5.1 制動(dòng)盤 31 5.2 制動(dòng)鉗 31 5.3 制動(dòng)塊 32 5.4 襯塊警報(bào)裝置設(shè)計(jì) 32 5.5 摩擦材料 32 5.6 制動(dòng)器間隙 33 5.7 緊固摩擦片鉚釘?shù)募羟袘?yīng)力驗(yàn)算 33 第6章 制動(dòng)驅(qū)動(dòng)機(jī)構(gòu)的型式選擇與設(shè)計(jì)計(jì)算 35 6.1 伺服制動(dòng)器的結(jié)構(gòu)形式選擇 35 6.2 制動(dòng)管路的多回路系統(tǒng) 36 結(jié)論 38 致謝 39 參考文獻(xiàn) 40 附錄1 41 附錄2 43 -4-
