1、Solidworks(cosmosworks )汽车驱动桥有限元分析摘要随着汽车对安全、节能、环保的不断重视，汽车后桥作为整车的一个关键部件，其产品的质量对整车的安全使用及整车性能的影响是非常大的，因而对汽车后桥进行有效的优化设计计算是非常必要的。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，而对于载重汽车显得尤为重要。当采用大功率发动机输出大的转矩以满足目前载重汽车的快速、重载的高效率、高效益的需要时，必须要搭配一个高效、可靠的驱动桥。驱动桥一般由主减速器、差速器、车轮传动装置和驱动桥壳等组成。所以采用传动效率高的单级减速驱动桥已成
2、为未来重载汽车的发展方向。本文参照传统驱动桥的设计方法进行了载重汽车驱动桥的设计。本文首先确定主要部件的结构型式和主要设计参数；然后参考类似驱动桥的结构，确定出总体设计方案；最后对主，从动锥齿轮，差速器圆锥行星齿轮，半轴齿轮，全浮式半轴和整体式桥壳的强度进行校核以及对支承轴承进行了寿命校核。本设计具有以下的优点：由于的是采用中央单级减速驱动桥，使得整个后桥的结构简单，制造工艺简单，从而大大的降低了制造成本。并且，弧齿锥齿轮的单级主减速器提高了后桥的传动效率，提高了传动的可行性。关键词：驱动桥,主减速器,差速器,半轴,桥壳AbstractTo sec
