Abstract] To reduce t he items of part s ponent s and lower t he manufact uring cost ,an indepen2 [ dent suspension/ in2wheel motor module is proposed for a 4WD elect ric vehicle. The module consist s of an in2 wheel motor ,a speed sensor ,a disc brake and a double2wishbone suspension mechanism. In particular ,t he basic formulae for t he kinematic analysis and design of double2wishbone suspension mechanism are derived based on t he t heory of spatial mechanism ,and a corresponding window style analysis and design ( software) system is devel2 前言 由轮毂电机直接驱动的四轮驱动燃料电池汽车,可省略传统内燃机汽车必须的机械式操纵换挡装置、离合器、自动变速器、传动轴和机械差速器等, 具有高效传动、整车结构简洁、可利用空间大的突出优点,是汽车传动方式的变革。借助现代计算机控制技术,可实现各电动轮电子差速、驱动防滑和直接横摆控制等,从而实现整车操纵稳定性与行驶性能的高性能化。对这种具有先进驱动和结构型式的洁 原稿收到日
