The invention discloses the resetting-mechanism of a kind of electronic throttle, including using the disk chip torsion spring of stalloy coiling, the inner of disk chip torsion spring is connected in axis hole, and the outer end of disk chip torsion spring is connected in valve body in step；Described axle stretches out that the top of disk chip torsion spring is fixing connects strip limited block, and the outer end of strip limited block is in valve body between two confined planes of step；Gap between described disk chip torsion spring adjacent stalloy from inside to outside is gradually reduced.Present configuration is simple, easy to assembly, and disk chip torsion spring volume is little, can be directly mounted at valve inner, electronic throttle volume can not only be reduced, and after using blanking cover to seal, the phenomenon that also can effectively prevent outside dust to be attached on spring, extend the service life of electronic throttle.
Description
Technical field
The present invention relates to the air throttle technical field of internal combustion engine, the resetting-mechanism in a kind of electronic throttle.
Background technology
Electronic throttle, as a kind of independent throttling arrangement, has been widely used for all kinds of conveying mechanical such as automobile, boats and ships
Electromotor on, Main Function is to improve the safety of running car, dynamic property, stationarity and economy, and reduces discharge dirt
Dye.
One of the applicant discloses a kind of electronic throttle in first patent CN101440749A, sets in electronic throttle
It is equipped with the resetting-mechanism that valve block is withdrawn into open position.Resetting-mechanism as it is shown in figure 1, include the limit outside torsion spring 1, valve body
Position block 4 and the limiting plate 6 on torsion spring top, torsion spring 1 is to use steel wire wound to become column, torsion spring set to be contained on axle 11, limiting plate 6
Being fixed on axle 11 end stretching out torsion spring top, one end 2 of torsion spring is connected in the draw-in groove 8 of the limited block outside valve body, pretension
After the torsion spring other end 5 be connected on limiting plate 6.When the valve block of electronic throttle is opened, axle valve block therewith rotates, the most spacing
Plate 6 rotates with axle 11；Valve block is then that valve block is withdrawn into open position by the effect by resetting-mechanism when closing.
But, there is problems in that 1 as the resetting-mechanism represented) power part of resetting-mechanism is torsion spring, torsion spring
Open at electronic throttle and there is upper and lower deformation during Guan Bi, therefore on the top of torsion spring, spring bearer plate 7 need to be set to torsion
Spring 1 carries out spacing, thus it is bigger to cause torsion spring to take volume at valve body.2) in actual use, it is arranged on valve because torsion spring 1 is exposed
Outside body 3, outside dust is easily attached on torsion spring 1, makes torsion spring easily get rusty and rotates dumb, further results in electronic throttle and loses
Effect.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of simple in construction, easy to assembly, small volume, are applied to electricity
Resetting-mechanism in sub-air throttle.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows.
The resetting-mechanism of a kind of electronic throttle, including the disk chip torsion spring of employing stalloy coiling, circular disc
The inner of formula torsion spring is connected in axis hole, and the outer end of disk chip torsion spring is connected in valve body in step；Described axle stretches out disk
The top of chip torsion spring is fixing connects strip limited block, the outer end of strip limited block be positioned at valve body step two confined planes it
Between.
The resetting-mechanism of above-mentioned a kind of electronic throttle, between described disk chip torsion spring adjacent stalloy from inside to outside
Gap be gradually reduced.
The resetting-mechanism of above-mentioned a kind of electronic throttle, described disk chip torsion spring is provided above periphery and is fixed on valve body
On blanking cover.
Owing to have employed above technical scheme, the invention technological progress is as follows.
Present configuration is simple, easy to assembly, and disk chip torsion spring uses stalloy coiling to form, and own vol is little, can
It is directly installed on valve inner, electronic throttle volume can not only be reduced, and after using blanking cover to seal, also can effectively prevent
The phenomenon that outside dust is attached on spring, extends the service life of electronic throttle.Owing to torsion spring is disk slice structure,
Deformation occurs in the horizontal direction, and will not produce deformation at vertical direction, the spring stop of the most desirable electronic throttle that disappears with
And the parts such as positive stop, reduce production cost and assembly difficulty.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
The resetting-mechanism of a kind of electronic throttle, its structure is as it is shown on figure 3, include that disk chip torsion spring 9 and strip are spacing
Block 16, is provided with interior step 14 in valve body, two confined planes 15,17 being provided with on step 14 in valve body；Disk chip torsion spring
The inner 10 be connected in axis hole 12, the outer end 13 of disk chip torsion spring is connected in valve body in step 14；Strip limited block 16
The inner fix and connect the top of axle stretching out disk chip torsion spring 9, the outer end of shape limited block 16 is positioned at valve body step 14
Between two confined planes.
Disk chip torsion spring 9 uses stalloy coiling to form, between disk chip torsion spring 9 adjacent stalloy from inside to outside
Gap be gradually reduced, as shown in Figure 2.There is not the phenomenon of axial deformation after disk chip torsion spring 9 pretension of the present invention, therefore turn round
Spring top is without arranging spring bearer plate 7, it is easy to install.
When the present invention applies in electronic throttle, disk chip torsion spring 9 is arranged in valve body 3, disk chip torsion spring
Inner 10 are stuck in axis hole 12, and the outer end 13 of the disk chip torsion spring after pretension is stuck in valve body on the confined planes 15 of step；?
Strip limited block 16 is installed on axle 11, when electronic throttle is placed in fully open position, strip limited block 16 and step in valve body
The contact of another confined planes 17 carries out spacing.After installing disk chip torsion spring 9, valve body 3 is installed a blanking cover 18 by circular disc
Formula torsion spring seals, and as shown in Figure 4, makes outside dust will be unable to enter in valve body 3, it is ensured that disk chip torsion spring 9 surrounding is clear
Clean, thus ensure that the reliability of electronic throttle.
