Key words:Double wishbone independent suspension ; torsion bar spring ; Independent suspension;off-road vehicles. 目录第1章绪论...............................................1 第1节悬架的发展历程与趋势...............................1 第2节本课题的基本内容...................................2 第2章悬架...............................................3 第1节悬架概述...........................................3 第2节悬架的分类与评价指标...............................4 第2节轮毂电机驱动的双横臂扭杆弹簧独立悬架...............9 第3章悬架主要参数的确定................................14 第1节悬架静挠度.........................................14 第2节悬架的动挠度.......................................15 第3节悬架弹性特性............................
