Description

Technical Field

[0001] The invention belongs to the electrical field, and in particular relates to a cable-hidden trailing arm suspension hub motor integrated module. Background Art

[0002] Electric vehicles are an important development trend in the current automotive industry, involving core technologies in vehicle engineering, motor drive control, electrical control, etc. Electric vehicle drive types mainly include wheel-side motor drive, bridge motor drive and hub motor drive. In terms of layout, the wheel-side motor and bridge motor drive types are similar to the traditional hydraulic drive type. The wheel-side motor and bridge motor are arranged on the inside of the car, connected to the wheel-side reducer through the wheel-side transmission half shaft, and the wheel speed and torque are adjusted by the motor controller; the hub motor drive type is a hub motor installed in the drive wheel to drive the wheel. The drive wheel can be controlled independently or as a whole, eliminating other transmission components. This drive type is conducive to overall layout and increased ground clearance.

[0003] The structural type of the suspension depends largely on the connection method of the vehicle's drive components. The matching method of independent suspension + wheel hub motor drive is widely used in the electric vehicle industry. In order to ensure a larger space inside the vehicle body, the longitudinal arm suspension type is widely used. This structural type makes the wiring harness of the wheel hub motor hang outside the longitudinal arm and twist with the longitudinal arm, causing the wiring harness to be hit or entangled by stones on the road. When the vehicle is used, the wiring harness twists with the longitudinal arm and may cause the wiring harness to be damaged, which is not conducive to the modularization and safety design of the vehicle.
