Keywords: Integral; Drive Axle; Final Drive; Differential; Axle; Drive Axle Housing  目 录 摘要 I II 第 1 1.1 设计目的及意义 1 1.2 国内外驱动桥研究状况 1 1.3 设计主要内容 3 驱动桥的总体方案确定 4 2.1驱动桥的种类结构和设计要求 4 2.1.1汽车车桥的种类 4 2.1.2驱动桥的种类 4 2.1.3驱动桥结构组成 4 2.1.4 驱动桥设计要求 5 2.2 设计车型主要参数 5 2.3主减速器结构方案的确定 2.3.1 主减速器的齿轮类型 5 2.3.2 主减速器的减速形式 7 2.3.3 主减速器主从动锥齿轮的支承形式及安装方法 2.4 差
