文档介绍：摘要
轮式装载机是以轮胎式拖拉机为基础车,安装上铲斗作为工作装置的一种土方工程机械。装载机的工作装置由铲斗、连杆、摇臂、动臂、转斗油缸、举升油缸组成,装载机的工作装置的合理性直接影响装载机的生产效率、工作负荷、动力与运动特性等。
本文参阅了大量的装载机设计的参考书,选择反转六连杆机构这种结构形式作为所设计的装载机的工作装置的结构。本文根据任务书中的要求,利用经验公式来计算确定铲斗的结构参数,装载机结构参数设计上,利用图解法确定动臂与铲斗、摇臂、机架,连杆与铲斗和摇臂等各个铰接点的位置,并对工作装置的各个部件的强度进行校核。最后文中对装载机的工作装置的限位机构进行了简要的介绍,最后利用AutoCAD对装载机工作装置的各零部件的结构参数进行详细的结构设计。

Abstract
Wheel loaders are based on car tires tractor, installation on a bucket as a working device earthmoving machinery. By a bucket loader working device, connecting rods, rocker, boom, the bucket cylinder, lifting ponents, Devices loader loader directly affect the rationality of production efficiency, workload, dynamic and kinematic characteristics.
This paper reviews a number of loader design reference books, select Reverse six linkage form such a structure designed as a loader working device structures. This book, based on the requirements of the task, Empirical formula to calculate the structural parameters of the bucket, Loader design of structural parameters, a graphical method to determine the boom and bucket, arm, chassis, connecting rod and rocker arm and bucket pivot point in various positions, then the text of the bucket by the force of a typical way of a detailed analysis, the working device and the strength of the ponents to be checked. Finally the text of the loader working device limiting mechanism are briefly introduced, and finally the use of AutoCAD loader working device on the structural parameters of the ponents detailed structural design.
Keywords: Wheel loaders, work equipment, architecture, design
