Frame design, using ladder frame, the frame is the role of the body to increase strength and rigidity, and to withstand bending and twisting load. This section is designed to focus on the structural design, focusing on its vertical beam settings, to determine its size, on the vehicle in which most vigorously by the dangerous cross-section strength, stiffness Verification, can meet the dangerous section of the frame is also satisfied by the power than its small force cross section, given the strength calculation method for precise calculations and checks made on the frame stress analysis, test the strength and stiffness of the frame qualified. Brake System Design, Brake through each of the major components of the braking force and Analysis of the size and dimension of the wheel brake pads and brake disc size, and round brake cylinder diameter size; The vehicle brake brakes forms is the former floating caliper brake, the brakes after leading from the foot brake, drive double-loop structure; Parking brake manually in the car, drive a mechanical drive. Through theoretical to the implementation, according to the overall parameters and structural parameters brake, of the cars braking performance so meticulous analysis.KEY WORDS : frame ,braking system , brakes , service brake ,parking brake目 錄第一章 前 言1第二章 車架設(shè)計22.1 概述22.2 車架的結(jié)構(gòu)設(shè)計22.2.1車架的結(jié)構(gòu)型式22.2.2車架的結(jié)構(gòu)設(shè)計42.3 車架的制造工藝及材料62.4 車架的計算72.4.1 車架的受載分析72.4.2 車架的設(shè)計計算82.4.3 縱梁的彎矩計算92.4.4 縱梁的抗彎截面系數(shù)的計算112.4.5 彎曲應(yīng)力計算122.4.6 車架的剛度校核122.5 車架實驗13第三章 制動系統(tǒng)設(shè)計143.1 概述143.2 制動器的結(jié)構(gòu)設(shè)計153.2.1 鼓式制動器163.2.2 盤式制動器193.3 制動器的設(shè)計計算213.3.1 制動力與制動力分配系數(shù)213.3.2 同步附著系數(shù) 243.3.3 前、后輪制動器制動力矩的確定253.4 制動驅(qū)動機(jī)構(gòu)及其設(shè)計計算273.4.1 制動驅(qū)動機(jī)構(gòu)的形式283.4.2 分路系統(tǒng)293.4.3 液壓驅(qū)動機(jī)構(gòu)的設(shè)計與計算303.5 應(yīng)急制動和駐車制動的計算313.5.1 應(yīng)急制動323.5.2 駐車制動323.6 制動器主要零件的結(jié)構(gòu)設(shè)計33第四章 總 結(jié)38參考文獻(xiàn)39致 謝40IV
