液力传动变速箱设计与仿真

摘要

本课题是设计一个液力传动变速箱，液力传动变速箱是汽车中的驱动设备，广泛的应用于叉车、牵引车、挖掘车等工业车辆中。根据本次设计的的要求，本论文是一个驱动60吨的液力传动变速箱设计过程。液力传动变速箱主要由变速箱、液力变矩器、油泵总成与主调压阀和溢流阀组件、操纵阀组件、离合器和液压控制等部分组成。由液力变矩器提供转矩和具有前进二档、后退二档共四个档位的动力换档变速箱，液力传动变速箱采用单级二相三工作轮综合式液力变矩器。液力变矩器使该液力传动变速箱具有液力传动输出的自动适应性，能随着外负载的变化而相应改变其输出扭矩和转速，而且要求能够吸收和消除来自发动机和外负载对传动系统的冲击振动。所采用的换档方式要求操纵简单、方便，起动平稳，较大地减轻操作者劳动强度。

本课题通过液力传动变速箱主要参数的设计，用三维设计软件Pro/E来实现液力传动变速箱的零部件造型和整机造型。在液力传动变速箱设计过程中，在投入生产之前利用计算机进行装配仿真，及时纠正设计中的不足。

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.
