The invention relates to a driving wheel assembly which comprises a reduction gearbox body, a transmission assembly, a driving motor and a wheel. The reduction gearbox body comprises a lateral mounting part and a transverse mounting part, a mounting space is formed between the lateral mounting part and the transverse mounting part, and an inner gear ring is also included; the wheel is rotatably mounted on the driving motor through a bearing; the wheel comprises a wheel core and a wheel flange, a protruding part is annularly arranged on an inner wall of the wheel core, and the two side surfacesof the protruding part abut against an outer side end surface of the inner gear ring and the bearing correspondingly; an outer circumferential surface of the driving motor is a stepped structure, andthe bearing is mounted at a maximum diameter position of the driving motor; and an elastic check ring assembly is arranged between the wheel core and the driving motor in a clamped mode. According tothe driving wheel assembly, technical problems that an electric forklift driving wheel can only disassemble and replace the wheel, a brake, a reduction gearbox left side cover and a motor need to bedisassembled for replacing the bearing and a second-stage driven inner gear ring, and disassembling is complex are solved.

    本发明涉及一种驱动轮总成,包括减速箱体、传动组件、驱动电机以及轮子,减速箱体包括侧向安装部以及横向安装部,侧向安装部与横向安装部之间形成一安装空间,还包括内齿圈;轮子通过轴承转动安装在驱动电机上;轮子包括轮芯以及轮缘,轮芯的内壁环设有凸起部,该凸起部两侧面分别与内齿圈的外侧端面以及轴承相抵靠;驱动电机的外圆周面为阶梯状结构,轴承安装于该驱动电机的最大直径位置处;轮芯与驱动电机之间卡合设置有弹性挡圈组件;本发明解决了该电动叉车驱动轮只能拆卸更换轮子,然而更换轴承和二级被动内齿圈需拆下制动器、拆下减速箱左侧盖、拆掉电机才可以,拆卸复杂的技术问题。
