摘要
随着我的提高。人们对禽类、肉类制品的需求量急剧增加。而畜禽的养殖场地远离市区,这样就需要将鲜活畜、禽运输到指定地点。因此畜禽运输车的市场需求量也较大。为了能够同时运输禽类和中大型动物,满足消费者和养殖业者的需要,并且从大幅度的提高运输效率、降低运输成本、减少运输途中的货损和货差,提高运输的安全性和减少污染保护环境的方面考虑,设计制造双层畜禽运输车成为专用汽车发展道路上的一项重要任务。
首先分析了现在畜禽运输车的现状和不足之处,明确了双层畜禽运输车的主要优点。在此基础上,通过对整体方案的分析选择、举升机构的计算校核、液压系统的选择与设计、辅助装置的选择与设计及对整车的性能分析,利用CAD软件绘制出二维图形。最后设计出的双层畜禽运输车能够满足工艺合理、小批量加工容易、成本低、可靠性高的加工和使用要求。

ABSTRACT
Along with the development of our national economy and improvement of people's living standard. People on the poultry, meat products demand has increased dramatically. And livestock and poultry breeding sites away from downtown, so it needs to fresh livestock and poultry transportation to the designated place. So the market demand of livestock transporters bigger also. In order to can simultaneously transport poultry and medium-large animals, meet the needs of consumers and aquaculture, and those from the large scale enhancement transportation efficiency and reduce the transportation cost, reduce transit goods damage and poor, improve transport safety and reduce pollution of environmental protection into consideration, design and manufacture of special cars double livestock transporters e the development path is an important task.
First analyzed the status and livestock transporters now deficiency, clear the double livestock transporters’ main this basis, through the analysis of the overall scheme selection, the calculation of lifting mechanism of dynamicrigidity, the selection and design of hydraulic system, auxiliary devices selection and design of the vehicle and the performance analysis, use CAD software rendering the 2d graphics
