Hydrodynamic, and save rubber seal.
The beneficial effects of the utility model are：Dynamic iron core and bulb integrated setting solve bulb and there is the risk to come off
Problem improves product reliability；Since sucking solenoid valve is two-step action mechanism, big flowed friction can be overcome, sucking is more
More brake fluid, compared with general ESP sucks electromagnetic valve structure, the magnetic structure of the utility model more optimizes, and improves electromagnetism
Valve dynamic response time and product Whole Response speed, reduce assembly difficulty, improve the reliability of product.
Description of the drawings
Fig. 1 is general sucking movable iron core of electromagnetic valve structure diagram；
Fig. 2 is the sectional view under the utility model solenoid valves state.
Specific embodiment
As shown in Fig. 2, a kind of automobile electron stabilization control system solenoid valve, including plunger tube 1, fixed core 2, dynamic iron
Core 3, the first return spring 4, the second return spring 5, spool 6 and valve seat 7, the fixed core 2 pass through laser welding with plunger tube 1
Connection is fixed, therefore fixed core is fixed, there is certain gap, the fixed core 2 between the fixed core 2 and dynamic iron core 3
It is connected between dynamic iron core 3 by the first return spring 4, the first return spring 4 has certain crush, makes electromagnetic valve coil
Fixed core and dynamic iron core can be separated during no power, the dynamic iron core 3, which is slided, to be set in plunger tube 1.
In the present embodiment, 3 upper end of dynamic iron core is equipped with two level recessed ledge frame, and the fixed core 2 is corresponding equipped with convex
Portion, the protrusion are inserted into dynamic iron core level-one step, and first return spring 4 is set in 3 two stage steps of dynamic iron core, is conducive to
Parts are assembled.
3 lower end of dynamic iron core is equipped with bulb 31, the bulb 31 and 3 integrated setting of dynamic iron core, solves bulb and exists
The risk problem to come off, improves product reliability.Under the action of the first return spring pressure, the bulb 31 resists spool
The valve port on 6 tops, the valve port match setting with bulb shape, and bulb can just block valve port.
The dynamic iron core 3 is connect by elastic support 8 with spool 6, second return spring 5 be set on elastic support 8 with
Between valve seat 7, the elastic support plays a part of providing support installation for the second return spring, is conducive to the second return spring
Installation place, and elastic support have a point elasticity.The rigidity of first return spring 4 is more than the second return spring 5
Rigidity, the spool 6 the pressure of gravity and the first return spring effect under clog valve seat 7, spool 6 is in the second return spring
Bulb 31 is headed under the action of 5 pressure upwards.
The spool 6 and elastic support 8, which slide, to be set in static iron core 9, and the static iron core 9 is set in valve body pedestal 10, institute
It states static iron core 9 to connect with the interference fit of valve body pedestal 10, is resistant to high-pressure brake liquid, and save rubber seal.The static iron core 9
Fixation is connect by laser welding with plunger tube 1.
9 side of static iron core offers oil inlet 11, and 7 lower end of valve seat offers oil outlet 12, the oil inlet
11 and oil outlet 12 be equipped with filter screen 13, by contaminant filter in oil inlet, oil outlet.
Operation principle：Brake fluid is flowed into from oil inlet, enters valve internal cavity by strainer, static iron core.
When coil is not powered on, under the first return spring and brake fluid pressure effect, the bulb of dynamic iron core blocks the valve of spool
Mouthful, spool is sealed with valve seat, is reached normally closed and is blocked oil circuit effect.
When the coil is energized, magnetic field is generated, a kind of electromagnetic force is generated to dynamic iron core, overcomes the spring force of the first return spring
It is adsorbed on fixed core, the bulb of dynamic iron core is detached with the valve port of spool, and brake fluid enters spool from the valve port of spool
In pipeline.When brake fluid pressure subtractive is small reaches certain value, elastic support and spool are under the action of the second return spring, upwards
It jacks up, the bulb of dynamic iron core blocks the valve port of spool again, and spool and valve seat separate, therefore the brake fluid of valve internal cavity is from valve
Big flow enters in the pipeline of spool between core and valve seat.
When the coil is de-energized, electromagnetic force disappears, under spool under the action of the first return spring and dynamic iron core its own gravity
Drop, valve seat and spool are sealed, and are reached normally closed and are blocked oil circuit effect.
