Abstract
The invention belongs to the field of automobile motors, discloses an axial-radial magnetic field electromagnetic planetary gear power divider and aims to solve the problems of large size, complex structure, high cost, performance limitation and failure in effective power output of a system due to the fact that engines in existing series, parallel and series-parallel driving devices cannot simply and efficiently match with other parts of the system. A shell is partitioned into two portions in which an axial birotor motor and a radial torque adjustment motor are arranged. A flux adjustment rotor with q projection units in the axial birotor motor is driven by a prime motor, stators form a field with the pole number of 2p, and the required rotation speed is outputted by an output shaft of a permanent magnetic rotor with the pole number of 2n, wherein p is equal to |hn+kq|. The output rotation speed is independent from the input rotation speed to realize stepless speed change. The radial torque adjustment motor inputs driving torques or braking torques according to actual load demands to meet actual torque requirements of loads so as to balance input energy and output energy of output shafts of permanent magnetic rotors.

Axial magnetic field modulated brushless double rotor motor described in Chinese patent CN101924436A and the electricity of present embodiment
The operation principle that machine adopts has certain similarity, but two schemes are not in terms of frame for movement, magnetic structure, motor performance
With, performance is as follows：
1., in frame for movement, the modulation rotor of CN101924436A scheme is located between stator and p-m rotor, and
And modulation rotor is to be made up of magnetic inductive block and non-magnetic block gap, does not allow by permeability magnetic material between two neighboring magnetic inductive block
It is made of one and so that it is connected, so just enable magnetic field modulation function, and then ensure the electromagnetic performance of motor.Therefore, existing side
The major issue that case faces be how to take into account motor electromagnetic performance ensure simultaneously again modulation rotor because of interval setting magnetic inductive block and
The non-magnetic piece of problems of mechanical strength brought.
Application scheme, adjustable magnetic rotor is located at innermost layer, and protrusion unit 7-1 of multiple magnetic conduction functions equally achieves magnetic field
Modulation function, and on magnetic circuit, these protrusion unit 7-1 need to make it connect just with permeability magnetic material to be more beneficial for the main magnetic of motor
Road flux closure (see main magnetic circuit path in Figure 23), thus ensure motor electromagnetic performance.Therefore, it is only necessary to adopt from structure
The integrated adjustable magnetic rotor with multiple protrusion unit 7-1 made by same permeability magnetic material, you can realize the adjustable magnetic of adjustable magnetic rotor 7
Function.And importantly, such structure makes the mechanical strength of adjustable magnetic rotor 7 significantly increase, thus solving existing side
The problem that motor performance in case and mechanical strength can not be taken into account.
According to the principles illustrated before present embodiment, the torque T of adjustable magnetic rotor 7mWill be greater than the first p-m rotor 6
Output torque TPM；Also " output torque T of modulation rotor 6 is described in CN101924436A3Will be greater than p-m rotor 7
Output torque T1" this technical characteristic, that is, the two is required to the torque more than permanent magnetism for the torque of adjustable magnetic, and this requires adjustable magnetic rotor
Intensity be greater than the intensity of p-m rotor, the structure of motor is just reasonable, and efficiency just can be higher, the electric machine structure of present embodiment
Exactly meet this feature, the electric machine structure of therefore present embodiment is more reasonable, in hgher efficiency.
2., on magnetic structure, the permanent magnet leakage magnetic circuit of CN101924436A only have passed through one layer of air gap (internal layer air gap L2)
(referring to Figure 22) can be closed, by contrast, the permanent magnet leakage magnetic circuit of present embodiment needs through two-layer air gap (internal layer air gap
L2 and outer layer air gap L1) (referring to Figure 23) could be closed, therefore, the motor of present embodiment is fewer than CN101924436A leakage field.
(CN101924436A taking the CN101924436A of same number of pole-pairs relation and present embodiment as a example：Stator number of pole-pairs is 4, forever
Magnet number of pole-pairs is 17, and magnetic conduction block number is 21；Present embodiment：Stator number of pole-pairs is 4, and permanent magnet pole logarithm is 17, and magnetic conduction is dashed forward
Playing unit 7-1 number is 21), the field waveform in ectonexine air gap L2 in two schemes respectively as Figure 24-Figure 27, contrast this 4
Figure it can be seen that due to the leakage path in two schemes different so that in present embodiment outer layer air gap field waveform
Differ markedly from the field waveform of outer layer air gap in CN101924436A, and in present embodiment outer layer air gap magnetic field amplitude
Also it is significantly greater than the magnetic field amplitude of outer layer air gap in CN101924436A.Therefore, excellent in magnetic path connection based on present embodiment
Gesture, present embodiment has more superior electromagnetic performance than CN101924436A.Still, right taking two above-mentioned concrete models as a example
The key technical index (back-emf, electromagnetic torque) of CN101924436A and present embodiment has carried out simulation analysis, emulation knot
Fruit such as Figure 28-Figure 30.From simulation result as can be seen that the back-emf amplitude of present embodiment is significantly greater than CN101924436A's
Back-emf amplitude；In present embodiment, the average electromagnetic torque of adjustable magnetic rotor is significantly greater than in CN101924436A and modulates rotor
Average electromagnetic torque；In present embodiment, the average electromagnetic torque of p-m rotor is significantly greater than in CN101924436A and modulates ring
The average electromagnetic torque of rotor.Therefore, compare CN101924436A, present embodiment can obtain higher torque density and work(
Rate density.

Adjust motor generation driving torque to torque to act on p-m rotor output shaft 9, thus it is guaranteed that p-m rotor output shaft 9
The torque of input and output balances each other.At this moment, an energy part for driving load is input to forever from radial direction double-rotor machine
Energy on magnet rotor output shaft 9, another part derives from the energy that radial direction torque adjusts motor input, so that p-m rotor
The energy amount phase equilibrium that output shaft 9 inputs and exports.
When the torque that radial direction double-rotor machine is input on p-m rotor output shaft 9 is equal with the torque that load needs,
Now radial direction torque adjusts motor and does not work.At this moment, the energy of driving load is all input to from radial direction double-rotor machine
Energy on p-m rotor output shaft 9, so that the energy amount phase equilibrium that p-m rotor output shaft 9 inputs and exports.
By above-mentioned analysis, it is operated in respectively under different rotational speed and torque states in electromotor and wheel-borne load, axle
It is accomplished that the speed-regulating function between electromotor and wheel-borne load to double-rotor machine；Radial direction torque regulation motor is accomplished that to be sent out
Tune square function between motivation and wheel-borne load.In terms of energy distribution angle, electromotor is delivered to axial double-rotor machine one
The mechanical energy of rotor, a part of mechanical energy passes to wheel-borne load by another rotor, and another part mechanical energy passes through stator
It is converted into electric energy to pass, this part electric energy is converted into mechanical energy through radial direction torque regulation motor again and passes to wheel simultaneously
Load.This electric machine structure of present embodiment can be used as electromagnetic planetary gear power divider.
