【摘要】：電液控制定軸式動(dòng)力換檔變速器是一種在工程機(jī)械中應(yīng)用比較廣泛的變速器,變速箱中的齒輪都是常嚙合的。采用的是液壓操縱的多片濕式摩擦離合器進(jìn)行換擋并且換擋時(shí)不必切斷動(dòng)力。因此,在變速箱中,換擋離合器性能的好壞對(duì)整個(gè)變速箱的性能的提升起著至關(guān)重要的作用。對(duì)其換擋離合器的結(jié)構(gòu)以及性能進(jìn)行分析研究具有很好的現(xiàn)實(shí)意義和經(jīng)濟(jì)價(jià)值。 本課題來源于鄭州大學(xué)機(jī)械工程學(xué)院與鄭州宇通重工的聯(lián)合申報(bào)的河南省重點(diǎn)科技攻關(guān)項(xiàng)目“電液換擋定軸式裝載機(jī)用變速器的研制”。在此過程中,我們通過對(duì)進(jìn)口的DANA32000型電液換擋定軸式變速箱換擋離合器的結(jié)構(gòu)以及性能進(jìn)行了系統(tǒng)的研究分析,得出了其工作原理,包括：機(jī)械、電控、液壓方面的工作機(jī)理,并在此基礎(chǔ)上,以8噸裝載機(jī)使用變速箱所需的一些技術(shù)要求為設(shè)計(jì)基準(zhǔn)重新進(jìn)行了設(shè)計(jì)。本文主要包括了以下兩方面的內(nèi)容： (1)針對(duì)8噸裝載機(jī)的設(shè)計(jì)要求,完成了以動(dòng)力裝備的選配為設(shè)計(jì)基礎(chǔ)的變速箱內(nèi)部傳動(dòng)系的分析、設(shè)計(jì)和計(jì)算；然后對(duì)換擋離合器進(jìn)行了設(shè)計(jì)計(jì)算并建立起了三維模型；在此基礎(chǔ)上對(duì)參與動(dòng)力傳動(dòng)的主要部件進(jìn)行了力學(xué)性能分析。 (2)利用系統(tǒng)高級(jí)建模與仿真軟件AMESim,以實(shí)際設(shè)計(jì)中的一些數(shù)據(jù)為參數(shù)建立了一組換擋離合器的工作仿真模型并對(duì)其工作特性進(jìn)行了分析研究。分析結(jié)果顯示,動(dòng)力傳動(dòng)的結(jié)構(gòu)件安全性良好；所設(shè)計(jì)的換擋離合器在液壓的控制下能夠較好的實(shí)現(xiàn)換擋。這為后期的樣機(jī)生產(chǎn)和物理實(shí)驗(yàn)的進(jìn)行提供了必要的技術(shù)基礎(chǔ)。
[Abstract]:Electro-hydraulic control fixed axis power shift transmission is a kind of transmission which is widely used in construction machinery. The gears in the gearbox are usually engaged. A hydraulic-operated multi-disc wet friction clutch is used to shift gears without cutting off the power. Therefore, in the gearbox, the performance of the gearshift clutch plays an important role in improving the performance of the whole gearbox. It is of great practical significance and economic value to analyze and study the structure and performance of the shift clutch. This subject comes from the joint application of Zhengzhou University School of Mechanical Engineering and Zhengzhou Yutong heavy Industry to tackle key scientific and technological problems in Henan Province, "the Development of Transmission for Electro-hydraulic shift fixed Axle Loader". In this process, the structure and performance of the imported DANA32000 type electro-hydraulic gearbox gearshift clutch are systematically studied and analyzed, and the working principles are obtained, including: mechanical, electrically controlled, hydraulic working mechanism. On this basis, some technical requirements for the use of the gearbox for the 8 ton loader are redesigned for the design benchmark. This paper mainly includes the following two aspects: 1) according to the design requirements of the 8 ton loader, the analysis, design and calculation of the transmission system of the gearbox based on the selection of power equipment are completed, and then the design and calculation of the shift clutch are carried out and the 3D model is established. On this basis, the mechanical properties of the main components involved in power transmission are analyzed. Using the advanced modeling and simulation software AMESimand taking some data in the actual design as parameters, a working simulation model of shift clutch is established and its working characteristics are analyzed and studied. The analysis results show that the structure of power transmission is safe and the designed shift clutch can shift gear well under the control of hydraulic pressure. This provides the necessary technical basis for the later prototype production and physical experiment.
