Simplify.
Description of the drawings
Fig. 1 is structural schematic diagram of the utility model novel electric vehicle with stator or so rotor driving motor.
Fig. 2 is another structural schematic diagram of the utility model novel electric vehicle with stator or so rotor driving motor.
Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, 2, a kind of novel electric vehicle is with stator or so rotor driving motor, including stator 1, rotor 2, turns
Sub- bearing 3, rotor mandrel 4, holder, stator 1, including stator core, shell and stator winding, engine base and power input thereon
Binding post.Rotor 2 includes left rotor, right rotor, rotor windings, rotor core, and 2 iron core of rotor is permanent magnet or excitation body or is
Permanent magnet excitation combines.At 2 both ends of rotor, multigroup rotor bearing 3 is respectively set, when ensureing that input power changes, rotor stability rotation
And without the speed discrepancy that left and right sidesing driving wheel when influencing vehicle turning generates.3 outside of rotor bearing is fixedly connected with stator case,
3 inside of rotor bearing is socketed with rotor 2；Rotor core is hollow left and right separated structure, is equipped on the inside of 2 hollow part of rotor
Rotor mandrel 4, rotor mandrel 4 are rotatablely connected by rotor bearing 3 and rotor 2, and 3 inside of rotor bearing is fixed with rotor mandrel 4
Connection.It, can be after in stator winding, installation is complete, between rotor mandrel center and stator to prevent rotor mandrel from shaking
One holder is installed, holder is the holder that non-magnetic material makes.
The external deceleration mechanism of above-mentioned left rotor, right rotor, and be connected with drive shaft.
Another way, 4 intermediate reel of rotor mandrel are fixedly connected with stator 1, ensure the stabilization of rotor axis 4.Rotor core
Axis 4 and its fixed reel manufacture for non-magnetic material.
At work：When advancing on straight road surface, driving wheel left and right wheels adhesive force or frictional force are identical, input voltage
When, 2 output power of left and right rotor, output rotating speed are identical, i.e. left and right sidesing driving wheel driving force is identical, automobile balance traveling.Work as automobile
Occur side fall into or a side drive wheel and traction reduce it is more in the case of (i.e. side tire is in the small frictions such as ice face
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 increase the larger driving wheel of frictional force power, so that car is more readily pulled from
Trapped situation.
Operation principle, after to same stator electromagnet coil switch power, bore of stator generate electromagnetism force direction be
Consistent, so the electromagnetism torsion direction transmitted to the concentric left and right rotor of same bore of stator is also consistent, however turn left
The torsion direction that the right axle shaft that the left half axle of son connection is connected with right rotor is provided to left and right sidesing driving wheel is in the same direction, according to this reality
Left and right rotor and bore of stator with novel product structure chart in same bore of stator ensure left and right in this way on same axial line
Rotor can be balanced in same bore of stator and be rotated smoothly, and the mechanically stable connection of left and right rotor is by left and right rotor internal cavity
Concentric shafts, be located by connecting using two pairs of precision bearings, in left and right, stator gives left and right rotor in the case of each rotor resistance difference
The torsion and rotating speed of offer will not interfere with each other, when advancing on straight road surface, driving wheel left and right wheels adhesive force or frictional force
Identical, when input voltage, 2 output power of left and right rotor, output rotating speed are identical, i.e. left and right sidesing driving wheel driving force is identical, and automobile is flat
Steady traveling.When there is a situation where another side drive wheel is hanging when driven wheel side is fallen into or skids with traction reduction for automobile
Under (or in the case that side tire is in the less frictions such as ice face), other side rotor is not influenced gives homonymy non-slip driving wheel
Powerful torsion is provided, car is made to be more readily pulled from trapped situation.
The foregoing is merely the embodiments for illustrating the utility model, are not intended to limit the utility model, for ability
For the technical staff in domain, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement
Deng should be included within the scope of protection of this utility model.
