Double-motor rotor structure

Abstract

The invention discloses a dual-motor rotor structure. The structure comprises a deflector rod, a joint sleeve, a positioning pin, a splined hub, a steel ball spring, a friction cone disc, a friction cone ring, a first rotor iron core, a sleeve shaft, a second rotor iron core and an output shaft, the deflector rod is connected with the joint sleeve, the positioning pin is slidably connected with the joint sleeve, and the splined hub is fixed on the output shaft. The steel ball is pressed in the joint sleeve through the spring, the friction cone ring is installed on the positioning pin, the friction cone ring makes contact with the friction cone disc through poking of the poking rod, the friction cone disc and the first rotor iron core are connected together, the sleeve shaft and the first rotor iron core are connected together, the sleeve shaft rotates on the output shaft, and the second rotor iron core is fixed to the output shaft. According to the double-motor rotor structure, the double motors can be freely switched between the single motor and the double motors according to different working conditions, the rotors do not rotate in the driven state, the motor loss is reduced, andthe motor efficiency is improved.

Description

Technical field: [0001] The invention relates to a dual-motor rotor structure, which belongs to the field of pure electric vehicles. Background technique: [0002] In recent years, with the continuous development of the new energy vehicle industry, major car companies and users have higher and higher requirements for new energy power systems, especially the structural form of the power system and the spatial layout of the vehicle. At present, domestic and foreign products mostly use the direct drive form of the drive motor and the traditional axle. The power is generated by the drive motor, and the power is transmitted to the drive axle through the transmission shaft through the gearbox to realize the drive of the whole vehicle. However, it is simple Most of the motor drive axle integrated structures are single motor structures. [0003] Since the efficiency of the motors is different under different working conditions, the multi-motor system can improve the efficiency of t...

Problems solved by technology

[0004] However, the above schemes have their own limitations. Due to the large size of the single motor, the problem of layout interference is often encountered, and there is also the problem that the front and rear axle motors cannot be shared. Although there are many dual-motor schemes on the market, for driven The rotor in the state of rotation will produce a certain loss when rotating, which will affect the efficiency of the motor
