Embodiment Construction

[0021] see figure 1 , the double-rotor motor for pure electric vehicles with retarding and differential functions in the present invention includes a left casing 4 and a right casing 11, and the outermost layer of the left casing 4 and the right casing 11 is an outer casing 24. The outer casing 24 is made of magnetic shielding material.

[0022] An inner rotor 5 , an inner rotor field coil 6 , an outer rotor 20 , an outer rotor field coil 21 , a permanent magnet 22 and a permanent magnet bracket 16 are arranged between the left side case 4 and the right side case 11 . The inner rotor 5 , the permanent magnet 22 and the outer rotor 20 are coaxially nested from inside to outside, and the left and right ends of the permanent magnet 22 are fixed on the permanent magnet bracket 16 by third screws 27 .

[0023] An outer rotor excitation coil 21 is wound inside the outer rotor 20 . The left end of the outer rotor 20 is fixedly connected to the left housing 4 through the second scre...

Abstract

The invention discloses a pure electric vehicle doubl- rotor motor with retardance and differential speed functions in the pure electric vehicle filed, and a working method thereof. An internal rotor coaxially sleeves the right segment of a first transmission shaft; the left segment of the first transmission shaft penetrates the left end of a permanent magnet holder and a left side casing; the first transmission shaft is in connection with the left end of the permanent magnet holder through a permanent magnet holder left axial bearing, and is in connection with a left side casing through a left side casing axial bearing; the right side of the first transmission shaft is a second transmission shaft; the central section of the second transmission shaft is in fixed connection with a right side casing; the left end of the second transmission shaft is in connection with the right end of the permanent magnet holder through a permanent magnet holder right axial bearing; a rotary motor is arranged between the right end of the first transmission shaft and the right end of the permanent magnet holder, and has the output shaft fixedly connected to the permanent magnet holder; the left end of the first transmission shaft is in connection with the left driving wheel of an automobile; the right side of the second transmission shaft is in connection with a right driving wheel. Accordingly, the motor realizes automobile driving, retardance and differential speed functions.

Description

technical field [0001] The invention relates to the field of pure electric vehicles, in particular to a double-rotor motor for pure electric vehicles. Background technique [0002] Traditional motors generally have only one stator and one rotor, whether it is a DC motor, a synchronous motor or an asynchronous motor, there is only one mechanical port. The dual-rotor motor that has appeared in recent years has two mechanical shafts, which can realize the independent transmission of energy from the two mechanical shafts. This new type of motor has the advantages of compact structure, simple layout, flexible control, and low cost. The coordinated work can replace the gearbox, starter and generator in pure electric vehicles, reducing the volume and weight of the power transmission part, improving the transmission efficiency, and better improving the fuel economy and emission performance of the vehicle. [0003] The retarder is a safety auxiliary device for commercial vehicle bra...
