Problems solved by technology

[0002] With the enhancement of people's awareness of environmental protection, electric bicycles with high efficiency and energy saving are more and more favored by people. The existing electric bicycle motor hubs are relatively large in size and the overall structure is not compact enough. If a motor controller is installed on the hub shell Components such as battery and battery will make the shape of the entire wheel hub appear bloated; secondly, the output torque of the existing electric bicycle hub is small, the work efficiency is low, and its working mode is increasingly unsuitable for such as large speed ratio deceleration, automatic differential speed adjustment and speed increase regulation. etc. Transmission Control Requirements

Embodiment Construction

[0023] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0024] like Figure 1 to Figure 2 As shown, an electric bicycle hub includes a main shaft 1, a hub housing 5 is installed on the main shaft 1 through a hub housing bearing 4, a motor and a planetary gear reduction mechanism for driving the hub housing 5 to rotate are installed in the hub housing 5, and the motor adopts The inner rotor 3 and the outer stator 2 have a double-rotor structure. The outer stator 2 is fixed on the inner wall of the hub shell 5 and can rotate together with the hub shell 5. The inner rotor 3 is fixed with the sun gear 6 sleeved on the main shaft 1. The sun gear 6 The planetary gear 7 is meshed, and the planetary gear 7 is meshed with the hub ring gear 8 fixed on the hub shell 5. The planetary gear 7 is installed on the planetary ge...

Abstract

A wheel hub of an electric bicycle, comprising a main shaft (1), wherein the main shaft (1) is provided with a wheel hub casing (5) by means of a wheel hub casing bearing (4); a motor and a planetary gear decelerating mechanism for driving the wheel hub casing (5) to rotate are provided inside the wheel hub casing (5); and the motor uses a structure with an internal rotor (3) and an external stator (2), the external stator (2) is fixed on the inner wall of the wheel hub casing (5) and is able to rotate along with the wheel hub casing (5), and the internal rotor (3) is connected with the planetary gear decelerating mechanism. The wheel hub of an electric bicycle has a small volume and a compact structure, and can implement large output torque and high work efficiency, and the working mode thereof can meet transmission control requirements such as high-speed-ratio deceleration, automatic differential speed regulation, acceleration, and speed regulation.

Description

technical field [0001] The invention relates to the field of electric bicycles, in particular to an electric bicycle hub. Background technique [0002] With the enhancement of people's awareness of environmental protection, electric bicycles with high efficiency and energy saving are more and more popular. The existing electric bicycle motor hubs are large in size and the overall structure is not compact enough. If a motor controller is installed on the hub shell Components such as battery and battery will make the shape of the entire hub appear bloated; secondly, the output torque of the existing electric bicycle hub is small, the work efficiency is low, and its working mode is increasingly unsuitable for such as large speed ratio deceleration, automatic adjustment of differential speed and speed increase. and other transmission control requirements. Contents of the invention [0003] The object of the present invention is to provide a compact and high-efficiency electri...
