The invention belongs to the technical field of new energy automobile electric driving and particularly relates to a two-stage speed reduction electric wheel adopting a full-disc brake. The wheel comprises a tire 1, a rim 2, a spoke plate 3, a hub 4, a steering knuckle assembly 5, a full-disc brake 6, an inner rotor hub motor 7 and a two-stage planetary gear reducer 8, wherein the rim 2 is arranged in the radial direction of the tire 1, the spoke plate 3 is mounted at one axial end of the rim 2, the hub 4 is mounted on an inner side of the spoke plate 3, the full-disc brake 6 is mounted on thesteering knuckle assembly 5, the inner rotor hub motor 7 is positioned on an outer side of the full-disc brake 6, the two-stage planetary gear speed reducer 8 is positioned on an outer side of the inner rotor hub motor 7, and the steering knuckle assembly 5 and the hub 4 penetrate through the center of the inner rotor hub motor 7 and the center of the full-disc brake 6. The wheel is advantaged inthat the wheel is reasonable in space utilization and force bearing path, small in required mechanical braking force, convenient for lightweight design of the brake, beneficial to integral integration of the electric wheel, low in heat dissipation requirement and capable of effectively preventing dust and fouling.

    本发明属于新能源汽车电驱动技术领域,尤其涉及一种采用全盘式制动器的两级减速电动轮。包括轮胎1、轮辋2、辐板3、轮毂4、转向节总成5、全盘式制动器6、内转子轮毂电机7和两级行星齿轮减速器8。所述轮辋2安装在轮胎1径向内部;辐板3安装在轮辋2轴向一端;轮毂4安装在辐板3内侧;全盘式制动器6安装在转向节总成5;内转子轮毂电机7位于全盘式制动器6外侧;两级行星齿轮减速器8位于内转子轮毂电机7外侧;转向节总成5与轮毂4从内转子轮毂电机7和全盘式制动器6中心穿过。本发明空间利用、承力路径合理,所需的机械制动力小,便于制动器的轻量化设计,利于电动轮整体集成,且散热需求降低,能够有效防尘、防污。
