黑龍江工程學(xué)院本科生畢業(yè)設(shè)計 I 摘 要 去年以來 我國專用車市場取得較好的經(jīng)營業(yè)績 全國 395家改裝車企業(yè)改裝汽 車 23 06萬輛 銷售 23 05萬輛 自卸汽車 27125輛 占總量的 11 76 其中輕型 農(nóng)用自卸車占據(jù)了很大比重 因為我國是農(nóng)業(yè)大國 因此輕型農(nóng)用自卸車是具有中國 特色的 國情車 主要應(yīng)用地區(qū)是廣大農(nóng)村 消費對象是廣大農(nóng)民 功能是以縣 鄉(xiāng)級道路短途運輸為主 其他作業(yè)為輔 專門為鄉(xiāng)鎮(zhèn)道路設(shè)計 本人通過對市場上出現(xiàn)的各種輕型農(nóng)用自卸汽車的車廂和舉升機構(gòu)進行了較詳細 地了解 確認了輕型農(nóng)用自卸車廂和舉升機構(gòu)的設(shè)計方案 較好地解決了自卸車設(shè)計 和制造成本較高的問題 給生產(chǎn) 改裝自卸汽車的生產(chǎn)企業(yè)提供了一種新思路 本文 首先對自卸車的設(shè)計特點以及國內(nèi)外發(fā)展現(xiàn)狀做了相關(guān)的概述 接著 從車廂的設(shè)計 舉升機構(gòu)的設(shè)計 液壓系統(tǒng)的設(shè)計等方面進行了 EQ3040B 自卸車的總體設(shè)計 其中 車廂設(shè)計主要有外形及自動開閉機構(gòu)的設(shè)計 舉升機構(gòu)設(shè)計中對舉升機構(gòu)進行了運動 分析和受力分析 然后在液壓系統(tǒng)設(shè)計中 對其工作原理進行了說明并通過計算得出 合理的液壓裝置 最后對自卸車副車架進行了設(shè)計 關(guān)鍵字 自卸汽車 車廂 副車架 舉升機構(gòu) 液壓系統(tǒng) 黑龍江工程學(xué)院本科生畢業(yè)設(shè)計 II ABSTRACT Since 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 frame dump truck has been designed Key words Dump truck Compartment Sub frame Lifting mechanism Hydraulic system
