Description
Technical field
The present invention relates to wheel hub power field, more particularly to many motor multi gear wheel hub mechanical gear shift dynamic structures.
Background technology
Electrical vehicular power developing direction is divided into the integrated power and wheel hub power of motor plus gear teeth case；Though single motor wheel hub power
Right speed is high, but same cost is also very high；It is reported that the wheel hub motor one of electric motor car only 4 that certain external university makes just is up to
Tens thousand of Euros.This is also the reason that the technology is also difficult to popularize on civilian use electric automobile.How gear teeth case and wheel
Hub combination will greatly improve performance, reduce cost, and this is the direction of current electrical vehicular power developmental research.It is now existing on the market
Single motor wheel hub power adds gear teeth box structure can not be solved so without batch application because of variety of problems.Existing traditional wheel hub
There are following difficulties in mechanical gear shift power wheel：
1. conventional boss mechanical gear shift power shift complex structure, generally is configured with the parts such as clutch, fork shift gear, gear shift meeting
Power is interrupted, especially climbing gear shift interruption power is dangerous high；
2. the loss of conventional boss mechanical gear shift power itself is high, the effect of energy-saving practical is not reached；
3. conventional boss mechanical gear shift power is bulky, so that relatively difficult in the application of compact car；
4. conventional boss mechanical gear shift power section sealing property is bad, part can not be protected；
5. the manufacturing cost of conventional boss mechanical gear shift power is expensive, cost performance is low, it is impossible to meet popular demand.
The content of the invention
The present invention provides many motor multi gear wheel hub mechanical gear shift power set, solves to change in existing wheel hub mechanical gear shift power
Mark structure is complicated, the problem of power is interrupted in gear shift.
The present invention solves the above problems by the following technical programs：
Many motor multi gear wheel hub power devices, including at least two motor, wear parts, fixing axle, wheel hub, enclosing cover, at least two
Sun gear and at least 2 groups planetary gears；
Sun gear is arranged in fixing axle by wear parts, and each design of electrical motor has motor output interface, and each motor passes through
Motor output interface is connected with sun gear；Wheel hub is designed as the disc structure of boring, planetary gear be arranged on hub interior and
The rotating shaft of planetary gear is fixedly mounted on wheel hub；Every group of planetary gear is engaged with a sun gear respectively；Motor is fixed on fixing axle
On.
In such scheme, sun gear point small sun gear and big sun gear, small sun gear and big sun gear by wear-resisting
Part is arranged in fixing axle.
In such scheme, planetary gear divides expert's star-wheel and layman's star-wheel, expert's star-wheel and Sunny gear teeth meshing；Outer planet
Wheel is with big solar wheeling tooth and engaging；Inside and outside planetary gear engagement is constrained each other；
In such scheme, wear parts are the part that bearing, oil sealing, wear-resistant sleeve etc. have antiwear characteristic material.
In such scheme, the number of teeth of the big sun gear of gear ratio of small sun gear is few.
In such scheme, design of electrical motor has three kinds of specification selections：External rotor electric machine, inner rotor motor or hollow-cup motor,
The mounting means of motor has homonymy to install and two kinds of both sides installation.
The beneficial effects of the invention are as follows：
1st, two or more motors are needed；According to road conditions fast slewing, the switching of speed and torsion is realized；With the high torsion of low or first gear,
The principle of the low torsion of top gear maximizes reasonable energy utilization.
2nd, motor needs stop control, and gear shift is not required to clutch, gear shift without impulsive force, stable drive, long service life, tooth
Take turns few, small, compact conformation of loss of quantity etc..
The 3rd, more motors can be installed, be connection in series-parallel relation, multi gear combination can be carried out, use demand can be more met.
