摘 要
隨著國(guó)內(nèi)經(jīng)濟(jì)變革與基建工程的大力開展,自卸車等商用車市場(chǎng)發(fā)展?jié)摿υ絹?lái)越巨大。但是隨著國(guó)內(nèi)經(jīng)濟(jì)的發(fā)展減緩,短時(shí)間內(nèi)自卸車的銷量會(huì)有所下滑或保持平穩(wěn)但是較之國(guó)外自卸車的發(fā)展,國(guó)內(nèi)自卸車發(fā)展還是較為落后。
本文的研究對(duì)象即為自卸車中的剪式高位自卸車的舉升機(jī)構(gòu)和液壓系統(tǒng),首先文中就自卸車經(jīng)行了簡(jiǎn)單的說(shuō)明,然后根據(jù)比較分析確定了剪式舉升機(jī)構(gòu)的參數(shù),根據(jù)數(shù)據(jù)要計(jì)算出相關(guān)數(shù)據(jù),并進(jìn)行了驗(yàn)證。當(dāng)然對(duì)于自卸車基礎(chǔ)系統(tǒng)-液壓系統(tǒng)我也進(jìn)行了相同的合理的計(jì)算分析。

Abstract
With the time going by,Chinese capital construction project and economic reform are vigorously carried out.The market prospect of commercial such as dump trucks is very good.However,since the domestic ecoomic development has been suspend this year ,the sale of dump will not increase for a short time.Hydraulic the object of this study is lifting mechanism and hydraulic mechanism of the scissors type dumptruck.Fist the length and length of scissors mechanism are determined according to the given parameters.Finally, according to the given parameters for verification.The design of the hydraulic system works the same way.
Key word:Dump truck, hydraulic system, scissors fork type
