Abstract

The invention provides an electric moped and a transmission device. The transmission device comprises a motor, a harmonic reducer and an output shaft. The motor comprises a rotor; the harmonic reducercomprises a wave generator, a flexible gear and a rigid gear, and the wave generator is in anti-torque connection with the rotor; and the output shaft is configured to be in anti-torque connection with the rigid gear or the flexible gear of the wave generator. By the adoption of the provided transmission device, the harmonic reducer and the motor are integrated so as to achieve speed reduction torque increase transmission, the large reduction ratio can be obtained in a limited installation space, transmission mechanisms such as the multi-stage gear transmission mechanism, the planet gear transmission mechanism and the bevel gear transmission mechanism are not needed, and a whole integrated transmission mechanism is more compact in structure, lighter in mass, higher in transmission efficiency and high in obtained output torque.

Description

technical field [0001] The embodiments of the present invention relate to the field of transmission technology, and in particular, to an electric power-assisted bicycle and a transmission device. Background technique [0002] Electric-assisted bicycles (Pedelec / EPAC / E-bike) refer to the installation of motors, controllers and other components on the basis of ordinary bicycles. Electric-assisted bicycles generally do not have a pure electric mode, but a hybrid power through "human power + electric power". For driving, because of the assistance of the motor, it will make the cyclist more labor-saving and relaxed. It can be used as a tool for daily commuting and leisure travel. In terms of appearance, electric bicycles are not much different from traditional bicycles. Compared with electric bicycles As far as the car is concerned, it looks very light. [0003] Electric power-assisted bicycles on the market rely on an auxiliary motor and multi-stage gear transmission or planeta...
