Abstract

The invention relates a continuously variable transmission driving system for magnetic gear transmission. The continuously variable transmission driving system comprises a magnetic gear and two permanent magnetic motor, wherein, one permanent magnetic motor is integrated with the outer gear of the magnetic gear and is connected with an output shaft; a magnet adjusting ring at the middle part of the magnetic gear is connected with a rotor of the other permanent magnetic motor and the rotate speed of the rotor is controllable; the inner ring of the magnetic gear is connected with a shaft of an engine for inputting the mechanical energy of the engine and the mechanical energy is output through the outer gear of the magnetic gear. By combining the two motors and the magnetic gear, the continuously variable transmission driving system can easily output high torque and realize the continuously variable mechanical energy transmission without contact and friction.

Description

technical field [0001] The invention relates to a continuously variable transmission drive system, in particular to a continuously variable transmission drive system driven by a magnetic gear, which is suitable for hybrid electric vehicles. Background technique [0002] At present, most of the continuously variable transmission systems of hybrid electric vehicles are composed of planetary gears and two motors. Since the three parts of the gears need to rotate and there are contact teeth, mechanical noise and wear will be caused. Contents of the invention [0003] The object of the present invention is to address the defects of the prior art and provide a continuously variable transmission drive system with magnetic gear transmission, which uses non-contact magnetic gears to replace the existing planetary gears to reduce mechanical noise and wear. In order to achieve the above object, the present invention adopts the following technical solutions: a continuously variable tr...
