The redundant electric steering double-wishbone independent suspension assembly comprises two sets of double-wishbone independent suspensions, each set of upper wishbone independent suspensions comprises an electric steering gear, and a machine body of each electric steering gear is fixedly arranged on an upper pin seat; according to the redundant electric steering double-wishbone independent suspension assembly, redundancy of the steering driving function of a system is achieved through the double electric steering gears, the requirement of the assembly for the output torque of the single electric steering gear is reduced, and the single electric steering gear can have the small appearance size. According to the double-electric-steering-gear system, the electric steering gears and the independent suspension structure are integrated together, the steering knuckles are connected through the splines, and therefore the steering knuckles are directly driven to swing, the occupied space of the double-electric-steering-gear system is reduced, and the total weight of the double-electric-steering-gear system is reduced.
本发明涉及一种冗余电动转向双横臂独立悬挂组件,包括两组双横臂独立悬挂,每组上横臂独立悬挂包括电动转向器,电动转向器的机体固设于上销座上,本发明的冗余电动转向双横臂独立悬挂组件采用双电动转向器实现了系统转向驱动功能的冗余,减小了组件对单个电动转向器输出扭矩的需求,使得单个电动转向器能够具有较小的外形尺寸。通过将电动转向器与独立悬架结构集成在一起,并通过花键连接转向节,从而使其直接驱动转向节摆动,进而减少了双电动转向器系统占用的空间,减轻了双电动转向器系统的总重量。
