摘 要 轻型汽车在商用汽车生产中占有很大的比重,而且驱动桥在整车中十分重要。驱动桥作为汽车四大总成之一,它的性能的好坏直接影响整车性能,而对于载货汽车显得尤为重要。为满足当前载货汽车的快速、高效率、高效益的需要时,必须要搭配一个高效、可靠的驱动桥。设计出结构简单、工作可靠、造价低廉的驱动桥,能大大降低整车生产的总成本,推动汽车经济的发展,所以本题设计一款结构优良的轻型货车驱动桥具有一定的实际意义。 本文首先确定主要部件的结构型式和主要设计参数,在分析驱动桥各部分结构形式、发展过程及其以往形式的优缺点的基础上,确定了总体设计方案,最后运用AUTOCAD完成装配图和主要零件图的绘制。 :轻型货车;驱动桥;单级主减速器;差速器;半轴;桥壳 ABSTRACTPickup trucks take a large proportion of commercial vehicles production, and the drive axle is one of the most important structure. Drive axle is the one of automobile four important assemblies,Its performance directly influence on the entire automobile,especially for the truck.Because using the big power engine with the big driving torque satisfied the need of high speed,heavy-loaded,high efficiency,high benefit today` truck, must exploiting the high driven efficiency single reduction final drive axle is becoming the trucks’ developing tendency.Design a simple. Reliable,low cost of the drive axle, can greatly reduce the total cost of vehicle production.so the title of the fine structure of the design of a pickup vehicle drive axle has a certain practical significance. In this paper, first of all determine the structure of major components and the main design parameters, the analysis of the various parts of the structure of the bridge drive type, the form of the development process and its advantages and disadvantages of the past, determined on the basis of the design program, using the traditional design method of various parts of the drive axle Main reducer, differential, axle, axle housing was designed to calculate and complete the check. Finally complete the final assembly drawing by using AUTOCAD and mapping the main components. Keywords: Pickup truck; Drive axle; Single reduction final drive; Differential; Axle; Drive Axle housing 第1章 绪 论 1.1 概述 本课题是对东风轻型货车驱动桥的结构设计。故本说明书将以“驱动桥设计”内容对驱动桥及其主要零部件的结构型式与设计计算作一一介绍 驱动桥的设计,由驱动桥的结构组成、功用、工作特点及设计要求,详细地分析了驱动桥总成的结构型式及布置方法;全面介绍了驱动桥车轮的传动装置和桥壳的各种结构型式与设计计算方法。 汽车驱动桥由桥壳、主减速器、差速器、半轴和壳体等元件组成
