Description
Technical field
The present invention relates to a kind of switch electromagnetic valve, the tool controlled in particular for automatic speed variator hydraulic system oil circuit break-make
There is the board-like high-speed switch magnetic valve of spherical structure armature.
Background technology
Automatic transmission is widely used in automotive field, and the executing agency of most automatic transmission is by all kinds of electricity
Magnet valve is controlled, magnetic valve applied to automatic transmission also because the characteristics of producer is with speed changer it is different have all styles of model with
Feature.High-speed switch magnetic valve is usually used in break-make and the switching of automatic transmission oil circuit, very fast with response speed, lasts a long time
The features such as.The raising of increase and comfortableness requirement with A/T gear position number, to the switch electromagnetism of control oil circuit switching
The response speed and traffic requirement of valve are higher.Plate switch magnetic valve uses in suction type electromagnet, its electromagnet and moves iron core
Armature is generally plate-sheet-type, can reduce the volume of solenoid part, and adhesive area is big, and lighter weight can equally pacify
Larger electromagnetic attraction is realized under the number of turn, faster response speed is realized, the corresponding speed within 10ms is reached.Due to board-like fast
Fast switch electromagnetic valve is simple in construction, compact the features such as, the automatic transmission such as car and engineering machinery are incorporated in extensively.
Applied to the board-like high-speed switch magnetic valve of automatic transmission, due to using plate-sheet-type armature structure, when armature with
When counterpart uses clearance sliding fit, unstable feelings when spigot surface curtailment causes armature motion when there is armature motion
Condition.Due to being limited by profile, unbraced structure is supported during general armature motion.Armature when being moved under electromagnetic force only according to
By itself web direction length as motion guide length, easily there is the situation of clamping stagnation.It is longer when the product working time, pollution
When thing enters the space of armature, it is easier to the situation that armature clamping stagnation causes magnetic valve not work occur.In order to reduce rank
The influence of iron motion guide curtailment, the armature motion stroke of general board-like high-speed switch magnetic valve is smaller so that electromagnetism
The flow of valve is smaller.When needing the larger plate switch magnetic valve of flow, often need to change the motion guide knot of board-like armature
Structure, guiding parts is used as by other parts to armature so that volume increase is more.Therefore, the small size of common armature structure,
The plate switch magnetic valve of big flow is typically difficult to realize.
The content of the invention
In order to solve armature caused by the existing board-like high-speed switch magnetic valve plate-sheet-type armature for automatic transmission
Be oriented to it is not enough caused by motion clamping stagnation, pollutant enter the magnetic valve Problem of Failure and plate switch valve of the appearance such as space because
Flow is compared with minor issue caused by structure qualification armature motion stroke, and the invention provides a kind of board-like with spherical structure feature
The high-speed switch magnetic valve of armature structure.Due on armature motion direction be spheroid character, even if armature motion stroke it is larger go out
The existing unilateral clamping stagnation of armature, armature is constant due to spherical diameter in the movement direction, unilateral can still be transported by the effect of electromagnetic force
It is dynamic（Small size swing is done using clamping stagnation point as the center of circle）, when armature motion to extremely close to buting iron when, rapidly increase due to electromagnetic force and
Riveting contacts the centripetal guide effect of buting iron sealing cone with the steel ball on armature, can drive by the armature motion of clamping stagnation to work
Make position.The armature clamping stagnation brought so as to solve the support of armature card slice structure without motion and guiding curtailment causes magnetic valve
The problem of failure.
To achieve the above object, the technical scheme is that：
A kind of board-like high-speed switch magnetic valve with spherical structure armature, including valve body, valve seat, armature, described valve
Internal cavity is provided with valve seat, armature, and steel ball is installed inside the armature provided with annular groove, and armature is connected with steel ball using riveting form
One is connected in, valve body is connected by pole shoe with stair-stepping buting iron, buting iron minor diameter part is caught in annular by the spring of socket
It is connected in groove with armature, buting iron is internally provided with stepped cylindrical hole, and buting iron right-hand member aperture is provided with cone structure, with steel ball
Constitute and be wound with coil outside sealing structure, buting iron, yoke is enclosed in outside coil, be connected with buting iron riveting positioning method.
Preferably, being provided with isolating pad between described valve body and pole shoe.
Preferably, described valve body is provided with least two radial direction circular hole as medium inlet, provided with least
More than two axis circular holes are used as media outlet.
Preferably, installing filter screen at described medium inlet.
It is integral preferably, described coil, buting iron and yoke are connected into using Plastic Package mode.
Preferably, being provided with input signal connector on described coil.
Preferably, described armature sheet type structure, radially with spherical structure feature, is made up of soft magnetic materials.
The present invention has advantages below compared with prior art：
1st, the present invention is using the armature with spherical structure feature, and armature is under electromagnetic force along valve body internal cavity to gear
Iron is moved, and spherical structure feature is enable armature when clamping stagnation occurs in armature, made the swing of certain amplitude as the center of circle using clamping stagnation point,
I.e. armature motion is while there is clamping stagnation, and the motion mating surface structure of its spheroid character causes armature still to can continue to motion, according to
The rapidly increase of electromagnetic attraction overcomes the clamping stagnation of armature during by armature close to buting iron so that armature motion to operating position.
2nd, present invention employs steel ball and the riveted structure of armature one, steel ball and buting iron right-hand member when armature is close to buting iron
Cone structure formation centering pilot effect, the steel ball armature integral to being riveted on plays certain castering action, departs from armature
Clamping stagnation point moves to operating position.
