液力傳動(dòng)變速箱設(shè)計(jì)與仿真
摘要
本課題是設(shè)計(jì)一個(gè)液力傳動(dòng)變速箱，液力傳動(dòng)變速箱是汽車中的驅(qū)動(dòng)設(shè)備，廣泛的應(yīng)用于叉車、牽引車、挖掘車等工業(yè)車輛中。根據(jù)本次設(shè)計(jì)的的要求，本論文是一個(gè)驅(qū)動(dòng)60噸的液力傳動(dòng)變速箱設(shè)計(jì)過(guò)程。液力傳動(dòng)變速箱主要由變速箱、液力變矩器、油泵總成與主調(diào)壓閥和溢流閥組件、操縱閥組件、離合器和液壓控制等部分組成。由液力變矩器提供轉(zhuǎn)矩和具有前進(jìn)二檔、后退二檔共四個(gè)檔位的動(dòng)力換檔變速箱，液力傳動(dòng)變速箱采用單級(jí)二相三工作輪綜合式液力變矩器。液力變矩器使該液力傳動(dòng)變速箱具有液力傳動(dòng)輸出的自動(dòng)適應(yīng)性，能隨著外負(fù)載的變化而相應(yīng)改變其輸出扭矩和轉(zhuǎn)速，而且要求能夠吸收和消除來(lái)自發(fā)動(dòng)機(jī)和外負(fù)載對(duì)傳動(dòng)系統(tǒng)的沖擊振動(dòng)。所采用的換檔方式要求操縱簡(jiǎn)單、方便，起動(dòng)平穩(wěn)，較大地減輕操作者勞動(dòng)強(qiáng)度。
本課題通過(guò)液力傳動(dòng)變速箱主要參數(shù)的設(shè)計(jì)，用三維設(shè)計(jì)軟件Pro/E來(lái)實(shí)現(xiàn)液力傳動(dòng)變速箱的零部件造型和整機(jī)造型。在液力傳動(dòng)變速箱設(shè)計(jì)過(guò)程中，在投入生產(chǎn)之前利用計(jì)算機(jī)進(jìn)行裝配仿真，及時(shí)糾正設(shè)計(jì)中的不足。

The Liquid Dint Spread To Move To Become Soon a Box a Design With Imitate True
ABSTRACT
This topic is a design a liquid dint spread to move to become soon a box, the liquid dint spread to move to become soon a box is in the car of drive an equipments, extensive of application at the fork car, lead a car and scoop out a car etc. industry vehicle in.According to this time design of of request, this thesis is soon a the liquid dint which drive 60 tons to spread to move to become box design process.The liquid dint spread to move to become soon a box main from become soon the box, liquid dint change Ju machine, oil pump total become with lord adjust to press valve and overflow to flow valve module and manipulate valve module, clutch and liquid to press control etc. part constitute.From the liquid dint change the Ju machine provide to turn Ju and have to go forward two files, retreat two files' motive of four total file shift gear to become soon a box, the liquid dint spread to move to become soon a box an adoption list class two mutually three work round comprehensive type liquid the dint change Ju machine.The liquid dint change the Ju machine make that liquid dint spread to move to become soon the box have liquid dint to spread to move output's auto adaptability, ability along with outside load of variety but correspond change it output twist Ju and turn soon, and request can absorb and cancellation come from launching machine and outside load to spread to move system of pound at vibration.Adoption of shift gear a way request to manipulate simple, convenience, start steady, compare the earth ease operation labor strength.
This topic through a liquid dint spread to move to become a box the design of the main parameter soon, use 3D design the software Pro/E come to realization liquid the dint spread to move to become soon zero parts shape and the whole machine shape of box.In the liquid dint spread move become soon the box the design the process, at devotion produce before make use of the calculator carry on assemble to imitate true, rectify a design in time in of shortage.
Keywords: The Liquid Dint Spread To Move To Become Soon A Box;Become Soon Box;The Liquid Dint Change Ju Machine;Clutch;Manipulate valve
