Background technology
During current electric automobile driving, dc motor or ac motor no matter is used to be both needed to match somebody with somebody differential mechanism
When solving automobile turning, while transmitting power to both sides semiaxis, it is allowed to which both sides semiaxis is rotated with different rotating speeds, meets both sides
Wheel makees Unequal distance traveling in the form of pure rolling as far as possible, reduces the friction on tire and ground.But when being fallen into vehicle generation side,
The electric automobile driven by differential mechanism then can not provide driving force to vehicle in this case makes vehicle be difficult to get rid of poverty, and makes
Seriously skidding vehicle will be difficult to a side drive wheel is run into normal driving process for the electric automobile starting driven with differential mechanism
Step and traveling stall cause difficult and dangerous to vehicle traveling, and the power for inputting differential mechanism will be by whole centralized distributions to hanging
Or the driving wheel that side is skidded, and the driving wheel of opposite side then loses driving force without any driving force, vehicle is obtained.
In order to tackle the problem of appearing above, it is necessary to design a kind of novel electric vehicle motor.
The content of the invention
It is contemplated that overcoming the defect of prior art to be driven there is provided a kind of novel electric vehicle with stator or so rotor
Motor, to solve the problem of prior art is present and reduce the demand to differential mechanism, and particularly drive to 4 wheel driven or entirely
The structure of electric car vehicle drive system more simplifies.
In order to solve the above-mentioned technical problem, the present invention provides following technical scheme：
A kind of novel electric vehicle is with stator or so rotor motor, including stator 1, rotor 2, rotor bearing 3, rotor
Mandrel 4, support, rotor 2 include left rotor, right rotor, rotor windings, rotor core, and a group rotor is respectively set at the two ends of rotor 2
Bearing 3, the outside of rotor bearing 3 is fixedly connected with stator case, and the inner side of rotor bearing 3 is socketed with rotor 2；Rotor core is hollow
Rotor mandrel 4 is installed on the inside of left and right isolating construction, the hollow part of rotor 2, rotor mandrel 4 passes through rotor bearing 3 and rotor 2
Connection is rotated, the inner side of rotor bearing 3 is fixedly connected with rotor shaft core 4.
Further, stator 1, including stator core, housing and stator winding, support and power input binding post thereon.
Further, rotor core is permanent magnet or excitation body or is that permanent magnet excitation is combined.
Further, left rotor, the external reducing gear of right rotor 2, and be connected with live axle.
Further, a support is installed between the center of rotor mandrel 4 and stator.
Further, support is the support that nonmagnetic substance makes.
Compared with prior art, the present invention has following beneficial effect：
The working characteristics of the motor of same stator using the present invention or so rotor, can replace differential mechanism and effectively solve
The difficulty occurred in being travelled more than certainly, makes vehicle traveling safer, and the structure of driving system for electric vehicles is more simplified.
Brief description of the drawings
Fig. 1 is structural representation of the novel electric vehicle of the present invention with stator or so rotor motor.
Fig. 2 is another structural representation of the novel electric vehicle of the present invention with stator or so rotor motor.
Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, 2, a kind of novel electric vehicle is with stator or so rotor motor, including stator 1, rotor 2, turns
Sub- bearing 3, rotor mandrel 4, support, stator 1, including stator core, housing and stator winding, support and power input thereon
Binding post.Rotor 2 includes left rotor, right rotor, rotor windings, rotor core, and the iron core of rotor 2 is permanent magnet or excitation body or is
Permanent magnet excitation is combined.Multigroup rotor bearing 3 is respectively set at the two ends of rotor 2, during ensureing that input power changes, rotor stability is rotated
And without the speed discrepancy that left and right sidesing driving wheel when having influence on vehicle turning is produced.The outside of rotor bearing 3 is fixedly connected with stator case,
The inner side of rotor bearing 3 is socketed with rotor 2；Rotor core is to be provided with the inside of hollow left and right isolating construction, the hollow part of rotor 2
Rotor mandrel 4, rotor mandrel 4 is rotated with rotor 2 by rotor bearing 3 and is connected, and the inner side of rotor bearing 3 is fixed with rotor shaft core 4
Connection., can be after stator winding installation, between rotor mandrel center and stator to prevent rotor mandrel from shaking
One support is installed, support is the support that nonmagnetic substance makes.
The external reducing gear of above-mentioned left rotor, right rotor, and be connected with live axle.
Another way, the middle reel of rotor mandrel 4 is fixedly connected with stator 1, it is ensured that the stabilization of rotor axis 4.Rotor core
Axle 4 and its fixed reel manufacture for nonmagnetic substance.
Operationally：When being advanced on straight road surface, driving wheel left and right wheels adhesive force or frictional force are identical, input voltage
When, the left and right power output of rotor 2, output speed are identical, i.e. left and right sidesing driving wheel driving force is identical, automobile balance traveling.Work as automobile
Generation side is fallen into or a side drive wheel and traction reduce it is more in the case of (i.e. side tire is in small frictions such as ice faces
In the case of power), the rotor 2 of the small side of frictional force is zero load, and input power all concentrates on the larger side of frictional force
Rotor 2 on, increase its outputting torsion, you can the power of the larger driving wheel of increase frictional force, be more readily pulled from car
Stranded situation.
Operation principle, after to same stator electromagnet coil switch power, the electromagnetism force direction produced in bore of stator is
Consistent, so the electromagnetism torsion direction to the concentric left and right rotor transmission of same bore of stator is also consistent, but turn left
The left half axle of son connection and the right axle shaft of right rotor connection are in the same direction to the torsion direction that left and right sidesing driving wheel is provided, according to this hair
Bright product structure figure so ensures left and right rotor in the left and right rotor and bore of stator of same bore of stator on same axial line
It can balance and rotate smoothly in same bore of stator, and the connection of the mechanically stable of left and right rotor is by the same of left and right rotor internal cavity
Heart axle, is located by connecting using two pairs of precision bearings, and in the case where each rotor resistance in left and right is different, stator is provided to left and right rotor
Torsion and rotating speed will not interfere with each other, when being advanced on straight road surface, driving wheel left and right wheels adhesive force or frictional force are identical,
During input voltage, the power output of left and right rotor 2, output speed are identical, i.e. left and right sidesing driving wheel driving force is identical, automobile balance row
Sail.When automobile occur another side drive wheel when driven wheel side is fallen into it is hanging or reduced with traction and in the case of skidding
(or in the case that side tire is in the less frictions such as ice face), the driving wheel for not influenceing opposite side rotor non-slip to homonymy is carried
For powerful torsion, car is set to be more readily pulled from stranded situation.
Explanation embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the technology of this area
For personnel, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in
Within protection scope of the present invention.
