The invention relates to the technical field of automobile transmission. The embodiment of the invention provides a vehicle and a drive axle device thereof. According to the vehicle and the drive axle device thereof, the drive axle device at least comprises the drive axle shell and the two electric power assemblies which are symmetrically arranged, and each electric power assembly comprises the drive motor, the brake and the planetary reducer. Thus, distributed driving is achieved, the rotating speed and 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 drive motors are arranged in the drive axle shell, and the two planetary reducers are arranged in the corresponding drive wheels respectively, so that the space utilization rate of the drive wheels and the drive axle is increased. Meanwhile, due to the fact that the two driving motors do not bear loads, the overall structure is more reliable and efficient.

    本申请涉及汽车传动技术领域,本申请实施例提供了一种车辆及其驱动桥装置。上述车辆及其驱动桥装置中,驱动桥装置至少包括驱动桥壳体以及对称布置的两个电动力总成,每一电动力总成中包括驱动电机、制动器和行星减速器。如此,实现分布式驱动,可以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。通过将两个驱动电机布置于驱动桥壳体内,两个行星减速器分别布置于对应的驱动轮内,提高了驱动轮和驱动桥的空间利用率。同时,由于两个驱动电机不承重,使得整体结构更加可靠及高效。
