摘要
Zl50装载机是我国轮式装载机系列中的中型产品,该机是一种较大型的以装卸散状物料为主的工程机械,广泛应用于矿山、基建、道路修筑、港口、货场、煤场等地进行装载、推土、铲挖、起重、牵引等作业。
Zl50装载机属于ZL系列,采用轮式行走系,液力机械传动系,交接时车架,工作装置采用液压操纵,所以该机具有机动性好、转向灵活、生产率高、操纵轻便等优点,另外,该机后桥布置为摆动桥,增加了整机的稳定性,所以该机安全性好。
Zl50装载机采用液力变矩器、动力换挡变速箱、四轮驱动、液压转向、嵌盘式制动器、铰接式车架的先进机构,具有牵引力大、操作方便、转弯半径小、作业效率高等优点。
本设计中采用行星式动力换挡变速箱,它具有3个离合器和3根轴,且轴安装在壳体内,使变速箱结构简单、便于维修。变速箱具有两个前进挡和一个后退档,可以产生三个速度。
设计步骤简单如下:,确定总体参数;,确定出各档及各档传动比;,并绘出总体布置图;,这是本设计中最主要的部分,确定传动比,设计传动简图,配齿计算,得出齿圈、行星轮、太阳轮的齿数,并验算其合理性。然后进行齿轮设计;,轴、轴承的设计及选择。

ABSTRACT
The loader ZL50 iswheel type and it is more bigger among the series made in our is suitable for loading discharging materials and it applies for mine、capital contuction、road builing 、port、field、coalfield and carries loading 、pushing dust 、diging rising weight
The loader ZL50 is ZL adopts whell type system、 liquid engine driving system、ream meet vehcle type、 working set of hydraulic pressure it has good flexibility 、 turn agility high productivity、 controlling handiness back bridge ,so increases the stability of whole machine,and it has a good security
Being quipped with advanced devices such as hydraulic torque conventer power shift gearbox four wheel driving、 hydraulic chuck disk break and artallated frame .So the loader model ZL50 is featured with high pulling capacity、 small turning of which make it possible for easy resulting in the high efficiency of our product .
In my design,I adopt counter shaft power shift transmission’s construction is simple and maincenance is easy .the transmission has two forward and one reverse gear ,it can provide three speeds
KEY WORDS: lorder liquid engine driving system
Hydraulic torque conventer power shift gearbox
