摘要
為解決城市垃圾運(yùn)輸，減少運(yùn)輸過(guò)程中的二次污染問(wèn)題，提高運(yùn)輸效率、降低工人勞動(dòng)強(qiáng)度，本課題研究設(shè)計(jì)了全密封壓縮式環(huán)保垃圾車(chē)。
本課題首先介紹了后裝壓縮式垃圾車(chē)總體設(shè)計(jì)的5個(gè)原則，然后對(duì)這6個(gè)原則依次進(jìn)行了詳細(xì)的論證分析，在此基礎(chǔ)上與傳統(tǒng)的垃圾車(chē)機(jī)構(gòu)進(jìn)行比較，確定了設(shè)計(jì)方案。①在設(shè)計(jì)計(jì)算部分，根據(jù)設(shè)計(jì)要求確定了垃圾車(chē)的結(jié)構(gòu)參數(shù)，并根據(jù)結(jié)構(gòu)參數(shù)對(duì)垃圾車(chē)的發(fā)動(dòng)機(jī)進(jìn)行了選型。②根據(jù)裝載要求，對(duì)后裝壓縮式垃圾車(chē)的整體結(jié)構(gòu)參數(shù)進(jìn)行了設(shè)計(jì)計(jì)算，其中包括料斗容積和污水箱容積的計(jì)算；③汽車(chē)底盤(pán)主要是二類(lèi)底盤(pán)的選用及其改造，根據(jù)載荷分布對(duì)各軸的負(fù)荷進(jìn)行了細(xì)化分配，同時(shí)對(duì)整車(chē)的性能參數(shù)也依據(jù)標(biāo)準(zhǔn)進(jìn)行了選用，主要確定了最高車(chē)速、燃料經(jīng)濟(jì)性參數(shù)、機(jī)動(dòng)性參數(shù)和通過(guò)性參數(shù)等；④以及對(duì)軸距、前后輪距、外廓尺寸等整車(chē)尺寸參數(shù)的確定；⑤為確保整車(chē)性能對(duì)車(chē)架進(jìn)行了受力分析和強(qiáng)度校核、液壓系統(tǒng)油缸的受力分析與強(qiáng)度校核。

Abstract
In order to solve the problems of town garbage transportation, two contamination in the transportation, thus improve the transportation efficiency, and reduce the worker labor intensity, this paper has designed the entire seal compression type garbage truck.
This topic first introduce the 5 principles in the overall design of back ward loading compression garbage truck, and then gave detailed proof analysis to the 5 principles. The author compares the new design with the traditional one. In design and the calculation part, the structure parameter of the garbage truck, and the engine of the dumpcart are chosen according with the requirements. According to the loading request, the design of the back ward loading compression type garbage truck are calculated, including the hopper volume and the dirt water tank volume computation. The motor car chassis is mainly on the chassis selections and the reformation, and the axes load distribution. In the same time, the entire vehicle performance parameter based on the standard has been selected, according to the maximum speed, the fuel economy parameter, the mobile parameter and passed the parameter and so on; and to confirm the parameters of axes distance, the distance of the front and back wheels, and the size of outside profile. In order to guarantee the completed car performance, have done the stress and strength checking, the stress analysis and strength checking of liquid pressure system.
Key words: Back loading；compression；garbage truck；environmental protection ；refuse transportation
