The invention relates to a drive axle device which comprises a drive axle shell and two electric power assemblies, the two electric power assemblies are symmetrically arranged on the two sides of a first central axis of the drive axle shell, and each electric power assembly comprises a drive motor, a first planetary reducer, a brake, a second planetary reducer and a drive wheel. The driving motor is sequentially connected with the first planetary reducer, the brake and the second planetary reducer through the half shaft, and the second planetary reducer is in transmission connection with the driving wheel. The two electric power assemblies are symmetrically arranged, and the driving motor, the first planetary reducer, the brake, the second planetary reducer and the driving wheel are arranged at intervals, so that distributed driving can be realized, the rotating speed and the torque of the driving wheel can be more conveniently controlled, and the transmission efficiency is improved; the first planetary reducer and the second planetary reducer are separately arranged, the speed ratio can be increased, it can be guaranteed that enough space is reserved in the driving wheel and the drive axle shell, and model selection of the brake is facilitated.

    本发明涉及一种驱动桥装置,包括驱动桥壳体及两电动力总成,两电动力总成沿对称设置于驱动桥壳体的第一中心轴线两侧,每一电动力总成包括驱动电机、第一行星减速器、制动器、第二行星减速器及驱动轮,驱动电机通过半轴依次连接第一行星减速器、制动器及第二行星减速器,第二行星减速器与驱动轮传动连接。通过将两电动力总成对称设置,且驱动电机、第一行星减速器、制动器、第二行星减速器及驱动轮间隔设置,能够实现分布式驱动,能够更方便地控制驱动轮的转速和扭矩,提高了传动效率;通过将第一行星减速器与第二行星减速器分开设置,既能够增大速比,又能够保证驱动轮内部及驱动桥壳体内部留有足够的空间,便于制动器的选型。
