Differential mechanism is usually the differential mechanism of bevel gear structure, is mainly used for shunting the input power conveyed via power input
Or it is assigned in two drive shafts.Differential mechanism is extremely frequently used as the so-called axle differential in automobile making.Here,
It is assigned on the wheel drive shaft of driven rotating wheel via differential mechanism by the driving power for driving engine to provide.In straight line
In the case of traveling, rotating wheel is identical to be rotated soon.In the case of negotiation of bends, the rotating speed of rotating wheel is different from each other.Vehicle bridge
Differential mechanism realizes the speed discrepancy.Rotating speed is free to adjust, and the average value of only the two speed is constant, and conventional carrier is located at
The low speed end of retarder, stress is larger, higher to the intensity requirement of differential gear so that and the volume of differential gear is larger,
Traditional cone gear differential mechanism scheme simultaneously, motor can not be mounted on the axis of differential mechanism-wheel, to necessarily take up volume
Outer space.

One differential spider wheel and the second differential spider wheel are individually fixed in first motor rotor and described second by axle sleeve
On rotor, the first driven wheel, the axially opposed planet carrier of first driven wheel are equipped in the planet carrier body
Be equipped with the second driven wheel in ontology, and be correspondingly arranged between first driven wheel and second driven wheel, described first from
Driving wheel and second driven wheel are engaged with the first differential spider wheel and the second differential spider wheel respectively, described
It is equipped with the first output shaft having a style of one's own with it at first driven wheel side, is equipped with and its self-contained at second driven wheel side
Second output shaft of one.
Preferably, between the first differential spider wheel and the second differential spider wheel engagement be formed with it is several
Planet pair.
Preferably, being fixedly connected by screw between the first motor rotor and second rotor.
Beneficial effects of the present invention：
Structure of the invention is compact, easy to use, among spur-gear differential is built in the rotor of permanent magnet synchronous motor, reduces
The volume of electric vehicle transmission link, improves power density and the speed end by the way that differential mechanism to be positioned over to retarder, subtracts
The small requirement to differential gear intensity, to reduce processing cost, and further reduces device volume, has good
Economic benefit and social benefit, suitable for promoting the use of.
