An electromotive wheel hub electromotor

Abstract

The invention relates to an electromobile boss motor which includes boss shell, end cap, retarder and motor parts, the motor parts include stator and rotor, the rotor is placed in stator, it characterized in that: said retarder composes retarder shell and underdriving gear set, the underdriving gear set is set in the retarder shell, input and output hole are separately set on two ends of the retarder shell, connecting axes is set on input hole, one end of connecting axes is engaged with underdriving gear set, the another end is connected with rotor, output of the underdriving gear set passes through the output axesof the retarder shell, clutch is between the output of the speed reduction gear and end cap. The structure of the product is compact, disassemble is convenient, performance is stable.

Description

technical field [0001] The invention relates to an electric vehicle motor, in particular to an electric wheel hub motor. Background technique [0002] In today's society, the use of clean and environmentally friendly means of transportation is vigorously advocated. Electric bicycles are favored by consumers because of their convenience, cleanness and pollution-free features. The hub motor of an electric bicycle is the core of an electric bicycle, and its performance will directly affect the performance of the entire vehicle. Performance, hub motors have gone through the process from carbon brush motors to brushless motors commonly used at present, from low-speed direct-drive motors in the past to the current high-speed deceleration drive mode, and the internal performance of the motor has been continuously improved. The hub motor of a bicycle has the characteristics of small starting current, large torque resistance, and low noise; however, the current electric hub motor is ...

[0002] In today's society, the use of clean and environmentally friendly means of transportation is vigorously advocated. Electric bicycles are favored by consumers because of their convenience, cleanness and pollution-free features. The hub motor of an electric bicycle is the core of an electric bicycle, and its performance will directly affect the performance of the entire vehicle. Performance, hub motors have gone through the process from carbon brush motors to brushless motors commonly used at present, from low-speed direct-drive motors in the past to the current high-speed deceleration drive mode, and the internal performance of the motor has been continuously improved. The hub motor of a bicycle has the characteristics of small starting current, large torque resistance, and low noise; however, the current electric hub motor is still an integral device, and all parts of the motor are wrapped inside the hub as a whole. Abnormal or damaged, because it is an integral setting, the entire motor must be disassembled, which is inconvenient for installation and maintenance. After disassembly, it will inevitably affect the tightness of the cooperation between the parts, especially the cooperation between the stator and the rotor, which will more or less affect the performance of the motor.
