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％。其中中型 自卸车占据了很大比重， 因为我国是农业大国， 因此中型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及建筑行业，消费对象是广大农民及建筑工地，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中型自卸汽车的车厢和举升机构进行了较详细地了 解，确认了东风尖头 140 自卸汽车的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东风尖头 140 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。

ABSTRACT
Since last year, our country private car market has obtained the good operating results, the national 395 stock car enterprises re-equips automobile 230,600, sells 230,500. Dump truck 27125, account for the total quantity 11.76%. And the medium dump truck occupied the very great proportion, because our country is the large agricultural nation, therefore the medium dump truck has the Chinese characteristic “the national condition vehicle”, mainly applies the area is the general countrysides and the building profession, expends the object is the general farmers and the Construction site, the function is by the county, the township level path short haul primarily, other works for auxiliary, specially for villages and towns road design. Myself through each kind of medium dump truck's compartment which and the lifting organization appeared to the market in carry on had understood in detail that confirmed the east wind tip 140 dump truck's compartments and the lifting organization's design proposal, has solved the dump truck design and the production cost high question well, for the production, the re-equipping dump truck's Production enterprise has provided one kind of new mentality. This article first has made the related outline to dump truck's design feature as well as the domestic and foreign development present situation. Then, from compartment's design, lifting organization's design, hydraulic system's aspects and so on design has carried on the east wind tip 140 dump truck's system designs. And, the compartment design mainly had the contour and the automatic switching mechanism design, in the lifting organization design has carried on the movement analysis and the stress analysis to the lifting organization, then in the hydraulic system design, has carried on the explanation to its principle of work and obtains the reasonable hydraulic unit through the computation. Finally has carried on the design to the dump truck sub-frame.
