A two-stage NGW planet structure wheel edge driving device comprises a rack coaxially arranged in a hub and further comprises a motor arranged on the inner side of the rack, a power output shaft of the motor is coaxially connected with a first-stage planet unit, and the first-stage planet unit is located on the outer side of the rack; a second-stage planetary unit is coaxially arranged between the first-stage planetary unit and the machine frame, the first-stage planetary unit and the second-stage planetary unit are in meshing transmission, and the second-stage planetary unit and the hub are in meshing transmission. Through reasonable design of parts and overall large-torque output, deformation of an inner gear ring is eliminated or reduced, a torque tube is omitted, fault risk points are reduced, and transmission stability and load uniformity are improved; meanwhile, unnecessary connecting pieces are reduced, the structure is compact, the system rigidity is improved, and the uniform load effect of the planet units is improved.

    一种两级NGW行星结构轮边驱动装置,包括同轴设在轮毂内的机架,还包括设在机架内侧的电机,电机的动力输出轴同轴连接一级行星单元,一级行星单元位于机架外侧;一级行星单元与机架间同轴设有二级行星单元,一级行星单元与二级行星单元间以及二级行星单元与轮毂间均啮合传动。通过部件的合理设计,整体大扭矩输出,消除或减小了内齿圈变形,取消扭力管,减少了故障风险点,提高传动稳定性和均载性;同时减少了非必要连接件,结构紧凑,提高系统刚度,改善行星单元均载效果。
