车辆工程毕业设计96东风轻型货车驱动桥设计.pdf

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，采用传统设计

方法对驱动桥各部件主减速器、差速器、半轴、桥壳进行设计计算并完成校核。最后

运用AUTOCAD完成装配图和主要零件图的绘制。
