The invention relates to the technical field of automobile transmission, in particular to a hub dual-motor driving device which comprises a hub, a tire, motors, a planetary gear mechanism and an output shaft, the tire is connected with the output shaft through the hub, the motors comprise the first motor and the second motor, stators of the first motor and the second motor are both fixedly arranged in a shell, and the planetary gear mechanism is arranged in the shell. A rotor of the first motor is connected with the output shaft through a planetary gear mechanism, a rotor of the second motor is connected with a sun wheel hollow shaft of the planetary gear mechanism through a supporting frame, and brake clutches are arranged between the rotor of the first motor and the shell and between the rotor of the second motor and the shell respectively. The two brake clutches are matched with the planetary gear mechanism and the double-motor drive hub, energy recovery and brake speed reduction capacity of different degrees can be achieved, driving power of different speed ratios is achieved, the structure is simple, cost is low, and integrated matching of a vehicle transmission system is facilitated.

    本发明涉及汽车传动技术领域,具体涉及一种轮毂双电机驱动装置,包括轮毂、轮胎、电机、行星齿轮机构、输出轴,所述轮胎通过轮毂与输出轴连接,所述电机包括第一电机、第二电机,所述第一电机、第二电机的定子均固定设置在壳体内,所述第一电机的转子通过行星齿轮机构与输出轴连接,所述第二电机的转子通过支撑架与行星齿轮机构的太阳轮空心轴连接,所述第一电机、第二电机的转子与壳体之间分别设有制动离合器。本发明通过两个制动离合器配合行星齿轮机构和双电机驱动轮毂,不但可以实现不同程度的能量回收以及制动减速能力,还实现了不同速比的驱动动力,结构简单、成本低,有利于车辆传动系统的集成匹配。
