A multifunctional electric wheel assembly comprises a hub, a hub motor, a brake device, a hub mounting frame, a steering power device, a mounting arm, a shock absorber, a mounting module, a large-diameter disc bearing, a lifting execution connecting rod and a reinforcing inclined strut. On the basis of the design of the high-power-density electric wheel, control strategies of respective driving, braking and steering are developed: specifically, by adopting the control strategy of combining vector control and flux weakening control, efficient and stable driving control over the electric wheel of the electric vehicle in a full-rotating-speed interval is achieved; and a controller for real-time operation of each unit is designed, a multi-mode suspension heightening function is adopted, and avehicle body is lifted in different modes according to different conditions. The invention further provides an electric drive walking device, which is provided with the multifunctional electric wheelassembly; and through the structural design, the multifunctional electric wheel assembly has the functions of driving, braking, 360-degree steering and suspension, and multifunction and modularizationof the electric wheel are truly achieved.

    一种多功能电动轮组件,包括轮毂、轮毂电机、制动装置、轮毂安装架、转向动力装置、安装臂、避震器、安装模块、大直径盘式轴承、升降执行连杆、加固斜撑。在高功率密度电动轮设计的基础上,开发各自驱动、制动、转向的控制策略:采用矢量控制和弱磁控制相结合的控制策略,实现对电动车电动轮全转速区间内高效、稳定的驱动控制。设计各个单元实时运行的控制器,采用多模式悬架调高功能,针对不同情况对车身进行不同模式的举升。本发明还提供了一种电驱动行走装置,安装有上述的多功能电动轮组件,通过上述结构设计,多功能电动轮组件具有驱动、制动、360°转向以及悬架功能,真正实现了电动轮的多功能化与模块化。
