Abstract

The invention discloses a coaxial central motor which comprises a machine shell, a middle shaft, a stator assembly, a rotor assembly, a speed change module and a clutch module. The stator assembly, the rotor assembly, the speed change module and the clutch module are located in the machine shell. The stator assembly is sleeved with the rotor assembly and connected to the machine shell, the middleshaft penetrates through the stator assembly, the rotor assembly, the speed change module and the clutch module, the speed change module is connected with the rotor assembly, the clutch module is connected with the middle shaft and the speed change module, and the middle shaft penetrates through the machine shell and stretches out of the machine shell. Through the above design, the axis of the stator assembly, the axis of the rotor assembly, the axis of the speed change module and the axis of the middle shaft coincide, the whole transmission process is simple, mechanical losses in the power output transmission process are small, and abrasion is not likely to be caused. The motor is low in noise during operation, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to a coaxial central motor, in particular to a coaxial central motor. Background technique [0002] In the field of electric power-assisted bicycles, the middle motor refers to the motor in which the drive motor of the electric power-assisted bicycle is installed in the middle of the body, that is, the pedal position. The motor is connected to the body and is connected to the rear wheel through a chain to transmit power. Pedals are installed on both sides of the bicycle, and the rider can ride the bicycle manually through the pedals, or choose a motor to ride with human power. In the existing market, the axis centers of the transmission shaft of the central motor and the transmission shaft of the pedal crank do not coincide, and there is a relatively large mechanical loss in the power output transmission process. The transmission process of the rotor assembly of the motor and the gear transmission mechanism is complicated, which ...
