内容简介：

黑龙江工程学院本科生毕业设计摘 要去年以来，我国专用车市场取得较好的经营业绩，全国395家改装车企业改装汽车23.06万辆，销售23.05万辆。自卸汽车27125辆，占总量的11.76。其中轻型农用自卸车占据了很大比重，因为我国是农业大国，因此轻型农用自卸车是具有中国特色的“国情车”，主要应用地区是广大农村，消费对象是广大农民，功能是以县、乡级道路短途运输为主，其他作业为辅，专门为乡镇道路设计。本人通过对市场上出现的各种轻型农用自卸汽车的车厢和举升机构进行了较详细地了解，确认了轻型农用自卸车厢和举升机构的设计方案，较好地解决了自卸车设计和制造成本较高的问题，给生产、改装自卸汽车的生产企业提供了一种新思路。本文首先对自卸车的设计特点以及国内外发展现状做了相关的概述。接着，从车厢的设计、举升机构的设计、液压系统的设计等方面进行了EQ3040B自卸车的总体设计。其中，车厢设计主要有外形及自动开闭机构的设计，举升机构设计中对举升机构进行了运动分析和受力分析，然后在液压系统设计中，对其工作原理进行了说明并通过计算得出合理的液压装置。最后对自卸车副车架进行了设计。关键字：自卸汽车 ；车厢 ；副车架；举升机构；液压系统ABSTRACTSince last year, our country private truck market has obtained the good management achievement, the national 395 stock truck enterprises re-equips automobile 230,600, sells 230,500.Dump truck 27125, account for the total quantity 11.76%.Light truck farm which occupied a large proportion, because China is a large agricultural country, agricultural truck is so light with Chinese characteristics national truck, the main application area is the vast rural areas, consumption is the broad masses of peasants, function based on the county, township roads mainly short-haul transport, other operations as a supplement, designed specifically for township roads. I appeared on the market through a variety of light agricultural vehicle dump body and the lifting of a more detailed understanding, confirmed the light compartment and the lifting of agricultural dump body design, a better solution to the design of a dump truck and the problem of higher manufacturing costs for production and modification of the production truck with a new idea. In this paper, the design features of the dump truck, as well as the development of the status quo at home and abroad to do an overview of the relevant. Then, from inside the design of the lifting body design, hydraulic system design aspects of the design truck EQ3040B. Among them, the inside design of the main form and automatic opening and closing body design, the design of lifting mechanism of the lifting mechanism for the motion analysis and force analysis, and then in the hydraulic system design, its working principle are described by come up with a reasonable calculation of the hydraulic device. Finally, Vice-fram
