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, each electric power assembly comprises a brake, a drive motor, a planetary reducer and a drive wheel, and the brake is sequentially connected with the drive motor and the planetary reducer through a half shaft. The two electric power assemblies are symmetrically arranged, and the driving motors, the brakes, the planetary reducers and the driving wheels are arranged at intervals, so that distributed driving can be realized, the rotating speed and the torque of the driving wheels can be more conveniently controlled, the transmission efficiency is improved, and electric power and braking energy are effectively utilized; the two brakes are arranged in the drive axle shell, the two drive motors and the two planetary reducers are arranged in the corresponding drive wheels respectively, and the space utilization rate in the drive wheels and the space utilization rate in the drive axle shell can be increased.
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制动器、驱动电机、行星减速器及驱动轮,制动器通过半轴依次连接驱动电机及行星减速器。通过将两电动力总成对称设置,且驱动电机、制动器、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,有效利用电功率和制动能量;通过将两制动器设置于驱动桥壳体内,将两驱动电机及两行星减速器分别设置于对应的驱动轮内,能够提高驱动轮内部和驱动桥壳体内部的空间利用率。
