Background technology
The environmental protection and the energy are the problems that receives much concern now, and for addressing these problems, auto industry is just at the accelerated development electric automobile.In the process of development electric automobile, driven by power and power supply are the key technologies that electric automobile need solve.Present electric automobile generally adopts monomotor to drive, and as shown in Figure 1, in this structure mechanical differential gear box must be housed, and travels to adapt to Ackermann steer angle left and right sidesing driving wheel differential.But the structure that mechanical differential gear box certainly will will add drive system is installed, increases the quality of car load, and then increase manufacturing cost.
The utility model content
The technical problems to be solved in the utility model is: a kind of differential speed type vehicle driving motor that directly has differential performance is provided, be intended to simplify drive system, alleviate car mass, improve mechanical efficiency, reduce manufacturing cost, help to accelerate electric automobile commercialization process.
The technical scheme that the utility model adopted is: differential speed type vehicle driving motor, has shell, brush is housed in the shell, brush links to each other with power supply wiring, internal rotor, inner rotor shaft, it is characterized in that also being provided with between shell and the internal rotor external rotor with the mutual backwards rotation of internal rotor, outer rotor shaft and inner rotor shaft are two output shafts of same axis, are equipped with on the outer rotor shaft and the corresponding conduction collecting ring of brush, and outer rotor shaft is connected with left side output semiaxis through left speed changer; Inner rotor shaft is connected with right output semiaxis through right speed changer.
The decelerator of described outer rotor shaft output is a gear reduction unit, and promptly left shaft end gear is equipped with in the end of outer rotor shaft, and it and left change-speed gearing mesh, and left change-speed gearing is contained on the left side output semiaxis.
The decelerator of described inner rotor shaft output is the decelerator of change gear in the middle of installing additional, right shaft end gear is equipped with in the end that is inner rotor shaft, it and middle change gear mesh, middle change gear and the engagement of right change-speed gearing, and right change-speed gearing is contained on the right output semiaxis.
The beneficial effects of the utility model are: through the improvement of mechanical structure, make motor realize birotor (no stator) running, two end output shafts have the differential characteristic, and mean speed is 1/2nd of a conventional motor, therefore this differential speed electromotor has following advantage: 1, cancelled mechanical differential gear box in the drive system of employing monomotor, made the drive system of electric automobile structure obtain simplifying reduced volume, reduce quality, reduce cost; 2,, when vehicle launch, acceleration, deceleration, quicken and the braking ability raising because birotor turns round, and rotating speed is low, has reduced moment of inertia; 3, the motor output shaft rotating speed is low, makes the decelerator gearratio reduce by one times, thereby has simplified speed changer structure, has improved transmission efficiency.

Embodiment
As can be seen from Figure 2, the fast device of two changes (subtracting) about this differential speed electromotor has, speed changer are given two driving wheels with transmission of torque again.
Present embodiment as shown in Figure 3, it has shell 1, brush 5 is housed in the shell, brush links to each other with power supply by power supply wiring 4, internal rotor 3 is enclosed within on the inner rotor shaft 3A, characteristics of the present utility model are that the stator component of conventional motor is designed to rotating external rotor 2, and promptly external rotor is between shell 1 and internal rotor 3, and the rotating shaft of external rotor 2 is outer rotor shaft 2A.During motor operation, because the relation of magnetic circuit active force and reaction force, inner and outer rotors is mutual backwards rotation, and differential action is arranged, it is external rotor faster rotational speed or when slowing down, the internal rotor rotating speed slows down or accelerates, and the problem that this example solves the mutual backwards rotation of inner and outer rotors is a change gear in the middle of adopting.Outer rotor shaft 2A and inner rotor shaft 3A are actually two output shafts that are in same axis, are equipped with on outer rotor shaft 2A and brush 5 corresponding conduction collecting rings 6, so just can make external rotor winding and power connection.
The output of outer rotor shaft 2A is equipped with left decelerator, and this decelerator is a gear reduction unit, and left shaft end gear 7 promptly is housed in the end of outer rotor shaft, and it and left change-speed gearing 9 mesh, and left change-speed gearing is contained on the left side output semiaxis 13.
The output of inner rotor shaft 3A is equipped with right decelerator, this decelerator also is a gear reduction unit, and to export semiaxis 13 identical for the direction of rotation that makes right output semiaxis 12 and a left side, change gear 10 in the middle of installing one again additional between the right shaft end gear 8 of inner rotor shaft end and the right change-speed gearing 11, right change-speed gearing are contained on the right output semiaxis 12.
About two output semiaxis connect with wheel left and right sides two-semiaxle respectively, powered vehicle constant speed or differential travel.
Present embodiment has only been introduced the one-level deceleration, and this embodiment is not limited in other embodiment under the same utility model design.Should consider as the case may be in the practical application to adopt one-level or multi-stage speed-reducing actually, or even the speed changer of other form.
Operation principle of the present utility model is: behind the motor connecting power, because the relation of magnetic circuit active force and reaction force makes the reciprocal direction rotation of inside and outside rotor, relative rotation speed is the motor designs rotating speed.When about during two output semiaxis constant speed drives, the rotating speed of internal rotor and external rotor is respectively 1/2nd of relative rotation speed.When vehicle was turned left, the left side wheel rotating speed was slack-off, and corresponding motor external rotor rotating speed is obstructed slack-off, and the magnetic circuit active force then promotes the reverse faster rotational speed of internal rotor, accelerated thereby drive right side wheels, played differential action automatically.When vehicle was turned right, vice versa.
Should consider during the differential speed type motor designs that inside and outside bitrochanteric moment of inertia is approaching as far as possible, need the requirement of frequent starting, speed change, braking to adapt to electric automobile.
