After university study, let us understand the prospects for the development of hydraulic drive technology, and to seriously study the working principle of the hydraulic transmission and hydraulic applications in daily life and to solve practical problems. In the graduation process, the students each made valuable suggestions and correct errors promptly corrected, so that our thesis can be successful。 the 2 / 36second part details the working principle of hydraulic and position。 我相信汽車起重技術(shù)將會在未來的國民經(jīng)濟發(fā)展中發(fā)揮著不可估量的作用，隨著液壓傳動技術(shù)的開發(fā)和利用，它將會再上一個新的臺階。其次通過這次畢業(yè)設(shè)計，讓自己更深刻的認識和理解了自己這個專業(yè)，認識了它的重要性欲實用性。在畢業(yè)設(shè)計過程，同學(xué)們相互提出了寶貴的意見并且及時糾正糾正的錯誤，從而使我們的畢業(yè)論文得以圓滿成功；同時在這次畢業(yè)論文的形成過程中我受益匪淺。1 / 36摘　要本篇論文在內(nèi)容上共分四個部分，即第一部分概述性地介紹了液壓傳動技術(shù)的含義、應(yīng)用及發(fā)展史；第二部分詳細說明了液壓傳動的工作原理及組成；第三部分著重就汽車起重機的液壓傳動系統(tǒng)進行了系統(tǒng)的分析；第四部分為液壓傳動系統(tǒng)中常見的故障分析。經(jīng)過大學(xué)的學(xué)習，讓我們了解了液壓傳動技術(shù)的發(fā)展前景，并且認真學(xué)習了液壓傳動的工作原理，以及液壓傳動技術(shù)在日常生活中的應(yīng)用和解決實際問題的方法。首先，在此過程中培養(yǎng)了我們分析實際問題和運用所學(xué)知識動手解決問題的能力，從而使所學(xué)知識達到鞏固，并且推廣和深化所學(xué)理論知識的范疇，為即將走向的工作崗位打下堅實的理論知識基礎(chǔ)。也是通過這次畢業(yè)設(shè)計更好的培養(yǎng)了自己獨立搜索資料和熟悉有關(guān)新興技術(shù)。關(guān)鍵詞：液壓傳動技術(shù) 汽車起重機 故障分析AbstractThe content of this paper is divided into four parts, namely, an overview of the first part of the hydraulic drive technology introduced in the meaning, application and development of history。 third part focuses on truck crane hydraulic system for the systematic analysis。 the same time during the formation of this thesis I benefited. First of all, trained in this process we analyze the practical problems and use the knowledge handson problemsolv
