文档介绍：摘要
为解决城市垃圾运输,减少运输过程中的二次污染问题,提高运输效率、降低工人劳动强度,本课题研究设计了全密封压缩式环保垃圾车。
本课题首先介绍了后装压缩式垃圾车总体设计的5个原则,然后对这6个原则依次进行了详细的论证分析,在此基础上与传统的垃圾车机构进行比较,确定了设计方案。①在设计计算部分,根据设计要求确定了垃圾车的结构参数,并根据结构参数对垃圾车的发动机进行了选型。②根据装载要求,对后装压缩式垃圾车的整体结构参数进行了设计计算,其中包括料斗容积和污水箱容积的计算;③汽车底盘主要是二类底盘的选用及其改造,根据载荷分布对各轴的负荷进行了细化分配,同时对整车的性能参数也依据标准进行了选用,主要确定了最高车速、燃料经济性参数、机动性参数和通过性参数等;④以及对轴距、前后轮距、外廓尺寸等整车尺寸参数的确定;⑤为确保整车性能对车架进行了受力分析和强度校核、液压系统油缸的受力分析与强度校核。

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 pression type garbage truck.
This topic first introduce the 5 principles in the overall design of back ward pression garbage truck, and then gave detailed proof analysis to the 5 principles. The pares 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 pression type garbage truck are calculated, including the hopper volume and the dirt water tank putation. 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 pleted car performance, have done the stress and strength checking, the stress analysis and strength checking of liquid pressure system.
Key words: Back pression;garbage truck;environmental protection ;refuse transportation
