Problems solved by technology

[0003] However, since planetary gears rely on the meshing of metal teeth to transmit torque, this adhesion mechanism inevitably brings many problems, such as friction loss, mechanical noise and vibration, and the need for regular maintenance and lubrication, etc.

Embodiment Construction

[0023] 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.

[0024] 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.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a gear change mechanism comprising a first switched reluctance motor and a second switched reluctance motor, wherein the first switched reluctance motor comprises a first stator and a first rotor which is contained in the first stator; a first rotating shaft and a coaxial magnetic gear are arranged on the first rotor; the coaxial magnetic gear successively comprises an inner rotor, a magnetism adjustment ring and an outer rotor from inside to outside; a permanent magnet pole pair is arranged at one side, near the magnetism adjustment ring, of each one of the inner rotor and the outer rotor; the outer rotor is connected with the first rotating shaft; the magnetism adjustment ring consists of a magnetism adjustment iron block and is provided with an input shaft; the second switched reluctance motor comprises a second stator and a second rotor which is contained in the second stator; and the second rotor is fixedly connected with the inner rotor. In the gear change mechanism, the harmonic drive and the speed regulation are realized depending on the magnetic field modulation effects of an inhomogeneous magnetic circuit. The non-contact variable transmission is realized by using the mutual effect of the permanent magnet by the coaxial magnetic gear, therefore, the defects of wear loss, mechanical noise, vibration and the like which are caused by a mechanical gear can be overcome when the gear change mechanism provided by the invention is applied to automobiles in a hybrid power mode and an electric power mode.

Description

【Technical field】 [0001] The invention relates to an automobile technology, in particular to a speed change device. 【Background technique】 [0002] A hybrid electric vehicle is equipped with two power sources, namely a conventional engine and a power storage battery. Generally, hybrid electric vehicles tend to choose the hybrid power coupling method because there are more energy transmission routes, but the structure tends to be complicated due to the separation and mixing of power. At present, general hybrid electric vehicles use mechanical gears such as planetary gears and two motors to form a variable speed transmission system. [0003] However, since planetary gears rely on the meshing of metal teeth to transmit torque, this sticky mechanism inevitably brings many problems, such as friction loss, mechanical noise and vibration, and the need for regular maintenance and lubrication. 【Content of invention】 [0004] In view of the above situation, it is necessary to prov...
