The invention discloses a two-stage speed reduction wheel edge assembly and a disconnected type multi-axle driving chassis. A transmission system positioning structure is designed for the two-stage speed reduction wheel edge assembly; radial double-fulcrum positioning of the hinged transmission shaft, radial positioning of the second-stage sun gear assembly and positioning of a gear ring support and a supporting shaft in the gear ring supporting assembly are achieved. According to the two-stage speed reduction wheel edge assembly, inclination of the central axis of each floating piece of the two-stage speed reduction wheel edge relative to the central axis of the supporting piece is reduced, the coaxiality of the rotating piece relative to the supporting piece is good, the centering capacity of the rotating piece under the high-speed working condition is improved, and the problem that a wear-resisting pad is abnormally abraded under the high-speed working condition of the wheel edge is solved; and the two-stage speed reduction wheel edge runs stably and reliably.

    本发明公开了一种双级减速轮边总成及断开式多桥驱动底盘,该双级减速轮边总成设计了传动系统定位结构,实现对铰接式传动轴进行径向双支点定位、对二级太阳轮总成进行径向定位、以及对齿圈支撑总成中的齿圈支撑与支撑轴进行定位。本发明的双级减速轮边总成减小了双级减速轮边各浮动件中心轴线相对于支撑件中心轴线的倾斜,旋转件相对于支撑件的同轴度好,提高了高速工况下旋转件的定心能力,解决了轮边在高速工况下耐磨垫异常磨损问题,使双级减速轮边运转平稳可靠。
