The upper surface of choke plate 9 is provided with fixing hole 12, fixing hole 12 and the rotation of the passive lower end of bevel gear 5 at the position of connect band 13
Axle 11 is engaged, and passive bevel gear 5 is mutually engaged with driving bevel gear 4, and wherein the connecting shaft of driving bevel gear 4 passes through shaft coupling 3
Be connected with motor 2, shaft coupling 3 can use gear coupling, this shaft coupling have compensation two axle axis relatively radially, axle
To the characteristic of, angle displacement, it is allowed to comprehensive displacement, it is easy under different structure, realizes transmission of the motor 2 to driving bevel gear 4
Function；Connecting rod 6 of the side wall of described rotary shaft 11 provided with horizontal direction, the other end of connecting rod 6 with it is vertical
The fixed block 7 for being arranged on the dynamic upper surface of choke plate 10 is connected, and wherein fixed block 7 is arranged in the middle part of the dynamic upper surface of choke plate 10
In slideway 8, electromagnet 2 15 and electromagnetism are provided with the described top same position for determining choke plate 9 and the lee face of dynamic choke plate 10
Iron 1.
Wherein, in actual applications, described motor 2 is the composite stepper motor of two-way axle, and rear end axle, which is provided with, to be embraced
Lock 1, driver is controlled and can communicated between CAN data/address bus by ECU, and composite stepper motor combines magneto
With the advantage of reaction stepping motor, big torque output can be achieved and noise is low, it is small to vibrate, there is preferable positional precision and motion
Repeatability, when vehicle is in high-speed travel state, CAN data/address bus sends the signal to ECU, and ECU gives according to pre-set programs
Motor 2 assigns instruction, and motor 2 engages passive bevel gear 5 by driving bevel gear 4, drives rotary shaft 11 to be rotated, rotary shaft
Dynamic choke plate 10 is gone to by connecting rod 6 in rotation process and determines the flush position of choke plate 9 by 11, now, determines the He of choke plate 9
The choke plate that dynamic choke plate 10 is constituted can be blocked and combed to flowing through the air-flow at wheel, in this state, and band-type brake 1 is by motor
2 lockings, keep in the center to prevent stop choke plate 10；When vehicle is in low-speed running state, by identical control system and holding
Row mechanism, dynamic choke plate 10 is gone to and determined after choke plate 9, and both are in folded state, reduces the front face area of choke plate, reduction
Local resistance at wheel.
Wherein, in actual applications, described driving bevel gear 4 and passive bevel gear 5 are spiral bevel gear, using 40Cr
Steel is made, and both are set into vertical stratification, and spiral bevel gear transmission smooth running, noise is small and bearing capacity is strong, when motor 2 is opened
After dynamic, horizontal conveyor is changed to by vertical-transmission by driving bevel gear 4 and passive bevel gear 5, and then drive rotary shaft 11 to carry out
Rotate；40Cr steel is middle carbon modulation steel, with optimal comprehensive mechanical property, suitable for manufacture driving parts, can effectively improve zero
The service life of part, so can both realize transmission needs, and be also convenient for the encapsulation of motor and transmission mechanism.
Wherein, in actual applications, described connecting rod 6 is the sleeve structure of fix bar or retractable, works as connection
When bar 6 is fix bar, the top of dynamic choke plate 10 is provided with the slideway 8 matched with fixed block 7, in embodiment one, connecting rod 6
For fix bar, the top of dynamic choke plate 10 is provided with the slideway 8 matched with fixed block 7, due to moving the center of circle that choke plate 10 rotates
It is inconsistent with the rotation center of connecting rod 6, so when rotary shaft 11 is being rotated, by fixed block 7 in the enterprising line slip of slideway 8,
The appearance of singular point is prevented, the folding and expansion of dynamic choke plate 10 is realized；In example two, connecting rod 6 is telescopic rod, works as rotation
Rotating shaft 11 is compensated when rotating by the flexible difference to radius of turn of connection 6, realize the folding of dynamic choke plate 10 with
Expansion.
Wherein, in actual applications, described determine choke plate 9 and dynamic choke plate 10 are made and both systems of carbon fiber
Make that size is identical, electromagnet 2 15 and electromagnet 1 be powered after magnetic on the contrary, carbon fiber light weight, intensity are big, weight is only
Equivalent to 20% to the 30% of steel, hardness is more than 10 times of steel, and therefore, choke plate is made of carbon fiber can be preferable
Meet vehicle lightweight demand, when dynamic choke plate 10 is folded under the drive of rotary shaft 11 to be determined after choke plate 9, to electromagnetism
Iron 1 and electromagnet 2 15 are powered, and there is a natural attraction between the sexes for both, is close to choke plate 10 and determines after choke plate 9 without moving
It is dynamic；When dynamic choke plate 10 deploys under the drive of rotary shaft 11, powered off to electromagnet 1 and electromagnet 2 15, both are no longer
It is attracting, it is easy to dynamic choke plate 10 to go at the position concordant with determining choke plate 9.
Wherein, in actual applications, described connect band 13, which is located at, determines the interior of choke plate 9 and the connecting portion of dynamic choke plate 10
Side, is made of vulcanization butadiene rubber, and inside is inlaid with arranges the steel wire soft ribbons set or carbon fiber with horizontal direction, and integral thickness is small
In 2mm, when dynamic choke plate 10 is gone to determine at the flush position of choke plate 9, because thickness is identical, it is possible to achieve windward side is put down
Whole property, and now connect band 13 is located at lee face, produced is raised relatively low on overall performance influence, it is to avoid because of choke plate itself
Structure causes air-flow to separate or produce vortex, and vulcanization butadiene rubber has excellent wearability, resistance to ag(e)ing and elasticity, dynamic load
Lower heating is few, and is internally inlaid with pierce tap or carbon fiber, on the premise of its flexibility is not influenceed, can improve its tough
Property, the connect band 13 of choke plate 9 and dynamic choke plate 10 is determined for making connection, its service life can be greatly prolonged.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention
Any simple modification, equivalent variations and the modification made to above example, in the range of still falling within technical solution of the present invention.
