Mark in accompanying drawing for：Upper shell 100, DC brushless motor 210, motor gear 220, location sensitive circuit board
300th, worm component 400, primary transmission gear wheel 410, secondary transmission worm screw 420, output drive gear 500, lower house 600.
Embodiment
With reference to Fig. 1-4, illustrate that the present invention forms the principle of high torque.
As shown in figure 1, the present invention includes upper shell 100, DC brushless motor 210, motor gear 220, location sensitive electricity
Road plate 300, primary transmission gear wheel 410, secondary transmission worm screw 420, output drive gear 500 and lower house 600.Motor gear
220 are assemblied on the motor shaft of DC brushless motor 210, form electric machine assembly 200；Primary transmission gear wheel 410 passes with two level
Dynamic worm screw 420 assemblies worm component 400.
As shown in Fig. 2 electric machine assembly 200 is arranged in the mounting groove position reserved on upper shell 100, worm component 400 is pacified
In the semicircle mounting groove reserved in upper shell 100；Worm component 400 and 200 parallel installation of electric machine assembly, and group of motors
Motor gear 220 contacts with the primary transmission gear wheel 410 in worm component 400 in part 200, forms first order transmission.
As shown in figure 3, output drive gear 500 is arranged on the circle on upper shell 100 by cylindrical structural thereon
Cavernous structure is placed in upper shell 100 the fan-shaped turbine portion on output gear 500 and the secondary transmission in worm component 400
Worm screw 420 contacts, and it is afterbody transmission to form the second level；Cylindrical structure other end fluting on output drive gear 500
It is connected with gear-box axle.
As shown in figure 4, the assembly state after being installed for lower house 600 by screw and upper shell 100.
Assembly is operationally：Motor gear 220 forms the first order with the primary transmission gear wheel 410 in worm component 400
Transmission, between 5-8, main function is to be passed in the high rotating speed for effectively lowering motor to whole for this grade of transmission speed reducing ratio design
While the impact of dynamic system, increase the moment of torsion of driving-chain, the also gearratio design to allow next stage to be driven there can be more multiselect
Select.
After deceleration：The worm component 400 that primary transmission gear wheel 410 forms with secondary transmission worm screw 420 turns
Speed has obvious reduction, and caused torque there has also been 5-8 times of increase.Secondary transmission worm screw 420 uses low modulus herein（m=
1 or 1.5）, head number uses relatively low standard value（Z=1）, the tooth number Z of output drive gear 500 of formed transmission, which designs, to exist
40-60, so the speed reducing ratio of second level transmission this grade that secondary transmission worm screw 420 and output drive gear 500 form is reachable
To 40-60.In summary the speed reducing ratio of first order transmission and second level transmission, system synthesis speed reducing ratio can reach 240-480.
The nominal operation torque of DC brushless motor 210 is in 0.12N.m, first order transmission motor gear 220 and one-level
The gear driving pair that gear wheel 410 forms is driven, transmission efficiency calculates by 0.85；Second level transmission secondary transmission worm screw 420
The worm-gear endless-screw type transmission formed with output drive gear 500, transmission efficiency calculate by 0.65；According to output torque and rotating speed
The calculation formula being inversely proportional（In the case where power is constant, the product of output torque and rotating speed is constant）, it is comprehensive according to system minimum
Close speed reducing ratio 240 to be calculated, output torque can reach 240 * of T=0.12N.m * 0.65,0.85=15.9N.m of *, i.e., most
15.9N.m is at least by moment of torsion of the output action of output drive gear 500 on gear-box axle eventually.Mainstream automotive speed change at present
The gearshift moment of torsion of case axle can reach 12N.m between 6N.m to 8N.m under maximum conditions, so this high torque output at present
Electric gear change executing agency can apply substantially on most main flow AT, DCT iso-variable velocity case, and still have more than moment of torsion
Amount.
Illustrate the principle of small volume of the present invention, as shown in Figures 5 and 6, worm component 400 and motor with reference to Fig. 5-6
Component 200 is placed in parallel, and direction be it is in the same direction, the design of the overall length of worm component 400 with 200 basic phase of electric machine assembly
Together, so saving volume to greatest extent on assembly width.Output drive gear 500 is arranged in upper shell 100
Afterwards, worm component 400 and electric machine assembly 200, small volume, and upper shell 100 part herein are less than on assembly width
It is designed according to the shape of output drive gear 500, further reduces assembly volume.Electric machine assembly 200, worm component 400,
Output drive gear 500 is respectively mounted at grade in upper shell 100, and assembly realizes minimum in the height direction,
Maximum height≤60mm.
In addition because the larger gearratio of the executing agency and moment of torsion amplification, the power of motor is also smaller, size
It is relatively small（Power has direct relation with motor volume）, so in the direction of the width, Breadth Maximum can≤100mm.
Electric machine assembly 200 is placed in parallel with worm component 400, because the number of teeth of motor gear 220 is smaller, is ensureing this grade of 5-8
Gearratio while, the size of primary transmission gear wheel 410 is also smaller（The number of teeth≤60）, so electric machine assembly 200 and worm screw
The axis centre of component 400 is away from the minimum also achieved as far as possible；The parts of tooth of worm screw 420 has used the design of the number of teeth=1,
The output drive gear 500 of formed transmission, in the case where realizing identical gearratio, realize the small-sized of gear
Change, so assembly Breadth Maximum≤130mm.（Such as：This grade transmission require gearratio 50, as the number of teeth of secondary transmission worm screw 400=
2, then the number of teeth of output drive gear 500 need to be 100；And if the number of teeth=1 of secondary transmission worm screw 400, then output drive gear
500 number of teeth only need to be 50, and under identical module, the number of teeth is more, and gear diameter is bigger）.
It is above embodiments of the invention, is not intended to limit the scope of the invention, it is every to utilize explanation of the invention
The equivalent structure or equivalent flow conversion that book and accompanying drawing content are made, or directly or indirectly it is used in other related technology necks
Domain, similarly it is included in the scope of patent protection of the present invention.
