Electric vehicle hub motor drive system, everyone is known to install the motor in the electric vehicle tire to do the drive, but the harsh use environment makes the reliability of the motor faces great challenges, such as tire brake heat and vibration of rough road Adverse environment, unsprung weight and other aspects of the impact on the vehicle, greatly put forward strict performance and test requirements on the reliability of the motor electronic control system, but also affect the safety, stability and controllability of electric vehicles.

  Then the electric vehicle wheel motor is installed on the frame structure, it effectively avoids the problems existing in the hub motor, in the weight structure to maintain the traditional vehicle tire structure, but also can have the advantages of the hub motor drive vehicle, such as modular distribution drive turning radius small transmission efficiency and strong mobility.

  However, if the traditional radial magnetic field motor is adopted, more frame chassis space will be occupied in the overall structure due to the longer axial size. If the axial magnetic field motor is adopted as the wheel motor of electric vehicle, the advantages of the axial magnetic field motor are short axial size and light weight, which will bring more space to the vehicle's manned cargo and battery, and at the same time, it is the power bottom Disk, the upper layer can be free to carry and combine various models to achieve personalized customized models.

  According to the size and requirements of the wheelside motor system of electric vehicles, Xiaxiang Electric independently developed the wheelside motor system driven by axial magnetic field motor. Because it is a modular power assembly on the chassis, integrated with shock absorber and steering motor, and at the same time, the by-wire brake calipers are installed in the tire, which is consistent with the traditional automobile tire, avoiding the problem of unspring weight, and the whole power module can be used With independent installation and replacement, convenient disassembly and replacement after failure, simple and standardized maintenance.

  The adoption of axial magnetic field motor as the power of the wheel drive system, can make the whole battery chassis space is larger, can realize personalized customized battery capacity car width car height and even car body modeling requirements of customization, can realize a variety of vehicle personality combination.
