关键词：汽车驱动桥，模块化设计，开发模式，整体性能，车桥市场前言随着我国经济的不断发展，目前我国已经成为世界第二大经济体，在经济发展的同时我国的汽车工业也迅猛的发展壮大，汽车工业随之带动了个汽车领域的零部件相关的产业链的发展。
驱动桥作为汽车四大总成之一，也跟随着汽车工业的发展而得到了相应的发展，国内的零部件厂家已经在研发生产过程中逐步形成了专业化、系列化、批量化生产的局面。
驱动桥位于汽车动力传动系的末端，其主要部分为：主减速器（轮边减速器）、差速器、车轮传动装置和驱动桥壳等,驱动桥的基本功能是传递扭矩、增大扭矩，同时合理的将扭矩分配给左、右驱动轮并实现差速功能，还需要承受各种复杂的力的作用。
驱动桥还对整车的机械性、可靠性、经济性等起着至关重要的作用。
虽然目前我国汽车工业已经得到了一定的发展，但就汽车驱动桥方面而言，我国仍旧存在诸多需要继续提升的地方，例如我们自主的研发能力还是有一定的局限性，现代先进的电子技术运用在产品的研发生产上的不够全面，现代产品设计分析方法没有得到充分的运用，生产自动化、智能化不够明显等。
