Mark in attached 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 housing 600.
Specific embodiment
With reference to Fig. 1-4, illustrate that the utility model forms the principle of high torque.
As shown in Figure 1, the utility model includes upper shell 100, DC brushless motor 210, motor gear 220, position sense
Answer circuit board 300, primary transmission gear wheel 410, secondary transmission worm screw 420, output drive gear 500 and lower housing 600.Motor
Gear 220 is assemblied on the motor shaft of DC brushless motor 210, forms electric machine assembly 200；Primary transmission gear wheel 410 and two
Grade geared worm 420 assemblies worm component 400.
As shown in Fig. 2, electric machine assembly 200 is mounted 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 motor group
Motor gear 220 is contacted 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 mounted 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 forms the second level, that is, afterbody transmission；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 housing 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 effectively to lower the high rotating speed of motor to entirely passing for this grade of transmission reduction ratio design
While the impact of dynamic system, increase the torque of driving-chain, the also gearratio design for next stage is allowed to be driven there can be more multiselect
It selects.
After deceleration：The worm component 400 that primary transmission gear wheel 410 is formed with secondary transmission worm screw 420 turns
Speed has an apparent reduction, and there has also been 5-8 times of increases for the torque of generation.Secondary transmission worm screw 420 uses low modulus herein（m=
1 or 1.5）, head number use relatively low standard value（Z=1）, 500 tooth number Z of output drive gear of formed transmission, which designs, to exist
40-60, so the reduction 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 reduction ratio of first order transmission and second level transmission, system synthesis reduction 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 level-one
The gear driving pair that gear wheel 410 forms is driven, transmission efficiency is calculated 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 are calculated 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
It closes reduction 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 torque of 500 output action of output drive gear on gear-box axle eventually.Mainstream automotive speed change at present
The gearshift torque of case axis 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 mainstream AT, DCT iso-variable velocity case, and still have more than torque
Amount.
Illustrate the small principle of the utility model with reference to Fig. 5-6, as shown in Figures 5 and 6, worm component 400 with
Electric machine assembly 200 is placed in parallel, and direction be it is in the same direction, the design of the overall length of worm component 400 it is basic with electric machine assembly 200
It is identical, so saving volume to greatest extent on assembly width.Output drive gear 500 is mounted on upper shell 100
In after, worm component 400 and electric machine assembly 200, small volume, and upper shell 100 is in this portion are less than on assembly width
Divide and be designed according to the shape of output drive gear 500, further reduce assembly volume.Electric machine assembly 200, worm component
400th, output drive gear 500 is respectively mounted at grade in upper shell 100, and assembly realizes minimum in the height direction
Change, maximum height≤60mm.
In addition because the larger gearratio of the executing agency and torque 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, maximum width can≤100mm.
Electric machine assembly 200 is placed in parallel with worm component 400, because 220 number of teeth of motor gear 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, realizes the small-sized of gear
Change, so assembly maximum width≤130mm.（Such as：This grade transmission require gearratio 50, as 400 number of teeth of secondary transmission worm screw=
2, then the number of teeth of output drive gear 500 need to be 100；And if 400 number of teeth=1 of secondary transmission worm screw, 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 the embodiment of the utility model above, it does not limit the scope of the patent of the present invention, every to utilize this
The equivalent structure or equivalent flow shift that utility model specification and accompanying drawing content are made directly or indirectly is used in other phases
The technical field of pass is similarly included in the scope of patent protection of the utility model.
