Problems solved by technology
[0002] Electric vehicles are now being developed and popularized globally, but the brake energy recovery technology commonly used in electric vehicles is relatively simple and the recovery rate is not high
Moreover, the structure of the power generation system of electric vehicles on the market is complex, and the structure of the original car needs to be modified during installation; in addition, the bearing structure in the power generation system usually uses metal as the bearing medium, so it is easy to generate noise and wear when the bearing is running. Serious, greatly shorten the service life of the bearing

Embodiment Construction
[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

A hub generator comprises a driven hub, a winding stator, a bearing and a permanent magnet rotor flywheel, wherein the bearing comprises an inner ring, an axial anti-thrust first outer ring, an axial anti-thrust second outer ring, radial bearing media and axial anti-thrust bearing media; the radial bearing media are injected in a first cavity and a second cavity; the axial anti-thrust bearing media are injected in a third cavity; and the permanent magnet rotor flywheel is arranged on the bearing, and rotates relative to the bearing along with air flow in a running process or a braking process of an automobile so that rotational speed difference can be formed between the permanent magnet rotor flywheel and the winding stator. The hub generator can be used even if the original parts of the automobile are not modified, only complete equipment is mounted directly and is connected with circuits, and the hub generator is convenient and speedy. Magnetorheological fluid serves as media of the bearing in the hub generator; when the bearing runs at high speed or in a heavy-load state, the three medium cavities are filled with pure liquid, and the circumstances of noise, heat and mechanical abrasion which are caused by rubbing of hard metals are avoided.
Description
technical field [0001] The invention relates to a generator, in particular to a hub generator used on an automobile hub. Background technique [0002] Electric vehicles are now being developed and popularized globally, but the brake energy recovery technology commonly used in electric vehicles is relatively simple and the recovery rate is not high. Moreover, the structure of the power generation system of electric vehicles on the market is complex, and the structure of the original car needs to be modified during installation; in addition, the bearing structure in the power generation system usually uses metal as the bearing medium, so it is easy to generate noise and wear when the bearing is running. Seriously, greatly shorten the service life of the bearing. Contents of the invention [0003] Based on this, it is necessary to provide a hub generator with simple structure and convenient installation. [0004] The hub motor includes a driven hub, a winding stator, a bear...
