Technical field
The present invention relates to electronic air throttle body, especially a kind of electronic air throttle body resetting-mechanism.
Background technique
Automotive electronics throttle body in the prior art has resetting structure, and structure please refers to Fig. 1-5.It is as shown in the figure:
It is made of throttle plate pin 1, reseting gear 2, coupling ring 3, EMR emergency reset spring 4, reset spring 5.Wherein: EMR emergency reset spring
4 one torque arm are hung in 2 spring groove of reseting gear, and another torque arm is hung in 3 spring groove of coupling ring.Coupling ring 3 passes through stretching
Two hooks on the reseting gear 2.5 one torque arm of reset spring are hung in the spring groove of coupling ring 3, and another torque arm is hung
On valve body.EMR emergency reset spring 4 and reset spring 5, which curl up, contrary can generate opposite torsion, the effect of reset spring 5
It is to make reseting gear 2 be returned to default location from any position of unlatching.The confined planes 8 of coupling ring 3 and reseting gear 2
Confined planes 9 contact, and from default location to air throttle full close position, EMR emergency reset spring 4 can generate opposite torsion and allow
Reseting gear 2 is opened.In air throttle default location, confined planes 10 and the valve body confined planes 7 of coupling ring are close together, limit
Face 8 and 9 under the action of EMR emergency reset spring because also stick together.
Although the design of above-mentioned resetting-mechanism solves the problems, such as reset, throttle valve body returns to default location, but cannot
It ensures product consistency, since mutually matched part is various, will appear many mismatch errors in manufacturing process, lead to reset machine
The point that structure returns to default location is also different.And mutual cooperation part is more, and frictional force increases, and also affects product reaction
Speed.
Summary of the invention
The purpose of the present invention is to provide a kind of electronic air throttle body resetting-mechanisms, it mainly solves existing electronic throttle
With part mutually matched in resetting-mechanism, various, manufacturing process is easy to appear mismatch error again, is returned to default location door body
The technical problems such as inaccurate, reaction speed is slow, its structure is simple, and manufacturing process simplifies, the default of throttle body easier to control
The precision of position.
To achieve the above object, the present invention is implemented as follows:
A kind of electronic air throttle body resetting-mechanism, it includes valve body, throttle plate pin, reseting gear；It is characterized by: it is also wrapped
Include upper spring seat, lower spring cup and reset spring；Axial outside the reseting gear to be provided with stabilizer blade, there are two sides for stabilizer blade tool；
The upper spring seat, reset spring, lower spring cup are sequentially sleeved at outside reseting gear；One torque arm of the reset spring is fixed on
On spring base, another torque arm is fixed on lower spring cup；The upper spring seat has upper spring seat branch instep, the upper spring seat stabilizer blade
Face corresponds to a side of stabilizer blade；The lower spring cup has lower spring cup branch instep, which corresponds to branch
Another side of foot；The throttle plate pin is connected on reseting gear after passing through lower spring cup, reset spring, upper spring seat；It should
There is valve body limited block, which has first side and second side in valve body；By default, upper spring seat
Branch instep had not only been attached in valve body limited block first side, but also was attached on one side of stabilizer blade of reseting gear；Lower spring cup stabilizer blade
Face had not only been attached in valve body limited block second side, but also was attached on another side of the stabilizer blade of reseting gear.
The electronic air throttle body resetting-mechanism, it is characterised in that: the reseting gear is by gear part and is connected to tooth
Rotation section below wheel portion is constituted；Axial outside the rotation section to be provided with stabilizer blade, there are two sides for stabilizer blade tool；The upper spring seat,
Reset spring, lower spring cup are sequentially sleeved at outside the rotation section of reseting gear.
The electronic air throttle body resetting-mechanism a, it is characterised in that: torque arm of the reset spring hangs over bullet
It is fixed in the slot of spring abutment, another torque arm, which is hung in the slot of lower spring cup, to be fixed.
The solution have the advantages that: compared to previous design EMR emergency reset mechanism, the present invention only uses a spring, protects
Card throttle blade be maintained at after a loss of power emergency point position mechanism, throttle blade can overcome torsional spring power carry out clockwise and
The rotation of both direction counterclockwise, and torsional spring guarantee can all be applied to reseting gear in both directions and return to emergency point position
Power.This structure saves original coupling ring and emergency spring, reduces the intermediate uncertainty connected, also reduces coupling ring rotation
When frictional force.

Specific embodiment
Fig. 6,7,8 are please referred to, the invention discloses a kind of electronic air throttle body resetting-mechanisms.As shown in the figure: it includes
Valve body 19, throttle plate pin 20, reseting gear 21, upper spring seat 11, lower spring cup 13 and reset spring 12.The reseting gear 21 by
Gear part 211 and the rotation section 212 for being connected to 211 lower section of gear part are constituted；It is axial outside the rotation section 212 to be provided with stabilizer blade 14,
There are two sides for the stabilizer blade 14 tool.The upper spring seat 11, reset spring 12, lower spring cup 13 are sequentially sleeved at reseting gear 21
Outside rotation section 212, in which: a torque arm of reset spring 12 is fixed on upper spring seat 11, and another torque arm is fixed on lower spring
On seat 13.The upper spring seat 11 has upper spring seat branch instep 16, which corresponds to one of stabilizer blade 14
Side；The lower spring cup 13 has lower spring cup branch instep 15, which corresponds to another of stabilizer blade 14
