The invention provides a large-torque non-disconnected drive axle hub motor. Comprising a transmission shaft, a deep groove ball bearing, a fixed bearing, a stator, a rotor and a torque increasing mechanism. Wherein the torque increasing device comprises a sun gear, a plurality of planet gears, a gear ring and a planet carrier flange, the torque increasing mechanism comprises a sun gear, a planet gear, a gear ring and a planet carrier, the sun gear is fixed to a fixed bearing, the planet gears are installed on the planet carrier and meshed with the gear ring and the sun gear at the same time, and the gear ring is fixed to a rotor disc of the rotor through bolts. A planet carrier of the torque increasing mechanism is connected with a transmission shaft through a bolt, and the planet carrier is connected with a fixed bearing through a deep groove ball bearing so as to ensure that the torque increasing mechanism is fixed in the radial direction and the planet carrier rotates. According to the hub motor, the rotor disc does not directly drive the transmission shaft and the hub to rotate, but the torque increasing device drives the transmission shaft and the hub to rotate, the torque increasing device is added, the output torque is effectively increased, the transmission efficiency is higher, and the vehicle driving requirement is met.
本发明提供了一种大扭矩非断开式驱动桥轮毂电机。包括传动轴、深沟球轴承、固定轴承、定子和转子和增扭机构。其中增扭装置包括:一个太阳轮、若干个行星轮、齿圈和行星架法兰,增扭机构包括太阳轮、行星轮、齿圈、行星架,太阳轮固定在固定轴承上,行星轮安装在行星架上,行星轮同时与齿圈和太阳轮啮合,齿圈通过螺栓与转子的转子盘固定,增扭机构的行星架通过螺栓与传动轴连接,行星架通过深沟球轴承与固定轴承连接,以保证增扭机构在径向上的固定和行星架的转动。本发明的轮毂电机由于转子盘不直接带动传动轴和轮毂转动,而是由增扭装置带动传动轴和轮毂转动,本发明加入了增扭装置,有效增大输出扭矩,使传动效率更高,满足车辆驱动要求。
