The invention relates to a double-speed hub reduction gear assembly and a drive axle assembly. The double-speed hub reduction gear assembly comprises a shell, a driving assembly, a transmission assembly, a power output assembly and a gear shifting assembly. The driving assembly is used for providing driving force; the transmission assembly comprises a first transmission part, a second transmission part and a mounting part, the first transmission part is used for transmitting the driving force of the driving assembly to the second transmission part, and the mounting part and the first transmission part are coaxially arranged; the power output assembly is used for outputting power transmitted by the second transmission part; the gear shifting assembly is arranged on the installation piece in a sleeving mode. The mounting part can be switched between the first state and the second state through the gear shifting assembly, and when the mounting part is in the first state, the first transmission ratio provides a high speed reduction ratio for the power output assembly so as to adapt to the low-speed and high-torque full-load working condition; and when the mounting frame is in the second state, the second transmission ratio provides high acceleration performance for the power output assembly so as to adapt to the high-speed low-torque no-load working condition, and the use requirements of different working conditions are met.

    本申请涉及一种双速轮边减速器总成及驱动桥总成,双速轮边减速器总成包括壳体、驱动组件、传动组件、动力输出组件和换挡组件。驱动组件用于提供驱动力;传动组件包括第一传动件、第二传动件和安装件,第一传动件用于将驱动组件的驱动力传递至第二传动件,安装件与第一传动件同轴设置;动力输出组件用于输出第二传动件传递的动力;换挡组件套设于安装件。通过换挡组件使得安装件能够在第一状态和第二状态之间切换,安装件处于第一状态时,第一传动比为动力输出组件提供较高的减速速比,以适应低速高扭的满载工况;安装架处于第二状态时,第二传动比为动力输出组件提供较高的加速性能,以适应高速低扭的空载工况,满足不同工况的使用需求。
