1、摘要在我國(guó)，車載起重機(jī)的發(fā)展已有五十年的歷史了，由于受到客觀條件的限制，一度發(fā)展較慢。進(jìn)入九十年代發(fā)展迅速，但與國(guó)際先進(jìn)水平還相差很遠(yuǎn)，主要表現(xiàn)在產(chǎn)品質(zhì)量的穩(wěn)定性、自動(dòng)化、智能化等方面。隨著國(guó)家基礎(chǔ)建設(shè)的規(guī)模不斷加大，許多生產(chǎn)場(chǎng)合都需要對(duì)設(shè)備、產(chǎn)品、零件、貨物等進(jìn)行搬運(yùn)和位移，車載起重機(jī)在起重運(yùn)輸行業(yè)和野外作業(yè)發(fā)揮的作用也將越來(lái)越大，市場(chǎng)也將越來(lái)越大。?汽車起重機(jī)液壓系統(tǒng)的設(shè)計(jì)是該型起重機(jī)設(shè)計(jì)過(guò)程中最關(guān)鍵的一步。本文首先對(duì)汽車起重機(jī)總體進(jìn)行初步設(shè)計(jì)，根據(jù)要求初步選擇部分參數(shù)。然后再根據(jù)液壓系統(tǒng)的技術(shù)指標(biāo)對(duì)該系統(tǒng)進(jìn)行整體方案設(shè)計(jì)。對(duì)其功能

2、和工作原理作進(jìn)一步的比較分析，確定了系統(tǒng)各回路的基本功能結(jié)構(gòu)及主要元件。設(shè)計(jì)的汽車起重機(jī)能夠滿足使用功能要求，安全可靠，結(jié)構(gòu)合理，重量輕，操作使用方便，對(duì)許多生產(chǎn)場(chǎng)合與起重運(yùn)輸?shù)刃袠I(yè)，具有很強(qiáng)的現(xiàn)實(shí)意義。關(guān)鍵詞：車載起重機(jī)，液壓系統(tǒng)，工作原理，基本功能AutomotiveTypicalHydraulicSystemDesign——CraneHydraulicSystemAbstractThedevelopmentofthevehicle-mountedcranehasmorethan50years’historyinourcountry
