Abstract
The invention relates to an engine waste gas recirculating system fitting, in particular to a diesel electronic throttle valve. The diesel electronic throttle valve comprises a valve body; a torsion spring cage is mounted in the valve body; a torsion spring is mounted on the torsion spring cage; two ends of the torsion spring form an included angle; a driven gear in a driven gear shaft module has a poking structure; the poking structure is inserted in the included angle; the torsion spring is a drum-shaped structure; the diameters of two end surfaces of the torsion spring are the smallest; the diameter of the middle of the torsion spring is the biggest; and the diameter from two end surfaces to middle is gradually changed. The diesel electronic throttle valve, provided by the invention, eliminates interference between the torsion spring and the valve body, and reduces wear of the torsion spring.
Description
Technical field
The present invention relates to engine exhaust-gas recirculating system accessory, specially diesel oil electronic throttle.
Background technology
Existing diesel oil electronic throttle, during valve original state, valve block initial position is standard-sized sheet, and torsion spring is not by driven gear
The shaft assembly active force to it, but after energising work, rotate after direct current generator energising, by transition gear driving torque to passive
Gear shaft assembly, in valve block closing process, switch structure drives torsion spring end face, and in this motor process, motor drives and makes every effort to overcome
Taking spring force, and when power-off behind valve plate movement closed position, valve block is during closing to and opening, and switch structure is made by torsion spring
With, drive the revolution of driven gear assembly, after arriving original initial position, because inertia force continues deflection, torsion spring other end end
To switch structure function, slow down the movement velocity of driven gear shaft assembly, driven gear can be avoided to touch mechanical position limitation, to tooth
The impact of wheel.
Existing diesel oil electronic throttle torsion spring is all linear, electronic throttle no matter from opening to closedown, or
Close to open, during this, torsion spring cannot keep straight line pattern, always has an elastic deformation, arise that it with
Interfering occurs in valve body, and such as encircled portion in Fig. 1, operationally, with valve body contact, can wear and tear torsion spring valve body and torsion spring, adds
Resistance, if serious wear valve will be made to open not thus cause defective valve less than maximum position or return, then this abrasion is produced
Scrap, bearing can be entered, thus cause the life-span of electronic throttle to decline.
Summary of the invention
The present invention solves that above valve work problem provides a kind of diesel oil electronic throttle spring structure, reduce torsion spring
Abrasion.
Concrete technical scheme is:
Diesel oil electronic throttle, including valve body, loads torsion spring retainer in valve body, torsion spring is installed on torsion spring retainer, torsion spring
Two ends shape has angle, and the driven gear in driven gear shaft assembly has switch structure, in the angle described in the insertion of switch structure；
Described torsion spring is drum organization, and the both ends of the surface diameter of torsion spring is minimum, and mid diameter is maximum, and both ends of the surface are to mid diameter gradual change.
The diesel oil electronic throttle that the present invention provides, eliminates the interference between torsion spring and valve body, decreases the abrasion of torsion spring.
The diesel oil electronic throttle that the present invention provides, simple in construction, little in equal load condition lower volume, light weight, material
Cost is reduced on material；Easy to assembly, when initially assembling, torsion spring own just needs one end to fix, and other end to rotate 270
Degree, before improvement, during spring assembling, because stress, spring can secundly, cause spring retainer to be difficult to install or cannot
Install, and after improving, then solve this problem；3. diesel oil electronic throttle is in the course of the work because being in deformation shape for a long time
State, causes spring to contact with spring retainer for a long time, it may appear that abrasion, and the torsion spring of the present invention is cydariform, only part and bullet
Spring retainer contacts, and decreases the abrasion of spring, and lower spring end diameter is less simultaneously, and lower spring end is difficult to have a downwarp, and departs from and dials dress
Mechanism, improves air throttle effectiveness, greatly strengthen the conforming product rate of diesel engine electronic air throttle, improves the use longevity
Life.

Detailed description of the invention
The detailed description of the invention of the accompanying drawings present invention.
As in figure 2 it is shown, be a complete diesel oil electronic throttle, including valve body 1, wavy spring 2, motor 3, screw 4,
Sealing ring 5, sensor 6, motor gear 7, transition gear 8, transition gear axle 9, sensor chip 10, driven gear shaft assembly
11, torsion spring retainer 12, needle bearing 13, torsion spring 14, back-up ring 15, screw 16, valve block 17, oilless bearing 18, blanking cover 19.
Concrete as it is shown on figure 3, load torsion spring retainer 12 in valve body 1, torsion spring 14 is installed on torsion spring retainer 12, torsion spring
The two ends shape of 14 has angle, and the driven gear in driven gear shaft assembly 11 has switch structure, described in the insertion of switch structure F
In angle；Described torsion spring 14 is drum organization, and the both ends of the surface diameter of torsion spring 14 is minimum, and mid diameter is maximum, both ends of the surface in
Between Diameter Gradual Change.
