The modern garbage truck design the status which holds in the private car design is also getting higher and higher. At present, garbage truck design universal existence changes to the high consumption, has certainly certainly with the current actual garbage truck market demand is uncoordinated, the cause high consumption's trash private car's consumption quantity is small. Regards the reality, from market realistic demand angle embarking, is perfect the design function reasonably, in satisfies the function request in the foundation, uses the new material, to truncate the low price, to hold the market superiority positively to take the design idea and the starting point, produces the function entire, the cost is low, the market demand many practical suspends the arm garbage truck. The main contact of the design as follows: first, it introduces the special-purpose automobile's development; secondly, it introduces the analysis and choose of the project; the project includes the design of the chassis, the assistant frame, the bracket and ensuring the total project. Thirdly, it introduces the design of special equipment, including the design of hydraulic pressure, the choose of the implement and the design of the waving arm of rubbish truck. Finally, it checks all the kinds of equipment and calulates the capability of the special-purpose automobile. Key words：Special-Purpose Automobile; The Waving Arm Of Garbage Truck; Hydraulic System; Suspending Arm 目 錄 摘要 Ι Abstract Ⅱ 第1章 緒論 1 1.1 專用汽車的發(fā)展 1 1.2 專用汽車概念和分類 3 1.3 專用汽車設(shè)計(jì)要求 3 1.4 擺臂式垃圾汽車的設(shè)計(jì)內(nèi)容 5 第2章 東風(fēng)擺臂式垃圾汽車底盤的選取 6 2.1底盤的選取 6 2.1.1汽車底盤選型要求 6 2.1.2底盤選型 6 2.1.3底盤的選取 7 2.2選用的底盤主車架的尺寸 8 2.3擺臂垃圾車質(zhì)量參數(shù)的估算 8 2.4本章小結(jié) 8 第3章 擺臂式垃圾車車廂結(jié)構(gòu)設(shè)計(jì) 10 3.1 車廂設(shè)計(jì) 10 3.2 車廂車斗的外形設(shè)計(jì) 11 3.2.1廂斗形狀的確定 11 3.2.2廂斗的尺寸設(shè)計(jì) 12 3.2.3廂斗選材 12 3.3 擺臂式垃圾車舉升機(jī)構(gòu)的設(shè)計(jì) 13 3.3.1擺臂液壓缸的選用 13 3.3.2擺臂的設(shè)計(jì) 14 3.3.3擺臂的受力分析 15 3.3.4擺臂的設(shè)計(jì)計(jì)算與校核 18 3.4支腿的設(shè)計(jì) 21 3.5總體結(jié)構(gòu)設(shè)計(jì) 22 3.6本章小結(jié) 23 第4章 擺臂式垃圾車副車架設(shè)計(jì) 24 4.1副車架截面形狀及尺寸 24 4.1.1副車架前端形狀及安裝位置 24 4.1.2縱梁與橫梁的鏈接設(shè)計(jì) 25 4.1.3副車架與主車架的連接設(shè)計(jì) 26 4.1.4副車架的形狀 27 4.2副車架主要尺寸及參數(shù)設(shè)計(jì)計(jì)算 27 4.2.1副車架主要尺寸設(shè)計(jì) 27 4.2.2副車架強(qiáng)度剛度彎曲適應(yīng)性校核 28 4.3本章小結(jié) 34 第5章 液壓系統(tǒng)設(shè)計(jì) 35 5.1液壓系統(tǒng)設(shè)計(jì)參數(shù)計(jì)算 35 5.1.1 擺臂舉升液壓缸選型與設(shè)計(jì) 35 5.1.2 擺臂舉升油泵的選型計(jì)算 36 5.1.3 支腿油缸選型計(jì)算 37 5.1.4 油箱容積與油管內(nèi)徑計(jì)算 38 5.1.5 方向控制閥的選型 39 5.2操縱方式的選型 39 5.3液壓系統(tǒng)原理 40 5.4取力器的選擇 41 5.5本章小結(jié) 42 第6章 東風(fēng)擺臂式垃圾汽車主要性能計(jì)算 43 6.1動(dòng)力性計(jì)算 43 6.1.1 發(fā)動(dòng)機(jī)外特性 43 6.1.2 汽車行駛方程式 43 6.1.3 動(dòng)力性評(píng)價(jià)指標(biāo)的計(jì)算 46 6.1.4 擺臂式垃圾車整車動(dòng)力性計(jì)算 48 6.2燃油經(jīng)濟(jì)性計(jì)算 51 6.3汽車穩(wěn)定性計(jì)算 52 6.4本章小結(jié) 53 結(jié)論 55 參考文獻(xiàn) 56 致謝 57 附錄 58 V
