Specific embodiment
The scheme of embodiment in order to enable those skilled in the art to better understand the present invention with reference to the accompanying drawing and is implemented
Mode is described in further detail the embodiment of the present invention.
For currently at low temperature due to the increase of gearbox inner fluid viscosity, the response characteristic of solenoid valve will drop significantly
It is low, and then phenomenon the problem of easily client is caused to complain there may be vehicle low-response, impact etc..The present invention provides a kind of for certainly
The electromagnetic pressure control valve of dynamic gearbox, by the way that multiple oil-feed ports, oil outlet and drain tap are arranged on valve pocket, to increase work
The free air space of oil liquid.Solving the problems, such as existing solenoid valve, that there are response characteristics is low in gearbox inner fluid viscosity great Yi, can mention
The response speed of high solenoid valve improves vehicle cryogenic property.
As shown in Figure 1, Figure 2 and Figure 4, a kind of electromagnetic pressure control valve for automatic gear-box, comprising: Electrical heads 1, valve
Core 2, valve pocket 3, spring 5 and feedback pin 4.The valve pocket 3 is equipped with inner cavity 35, oil-feed port 31, oil outlet 32 and drain tap 33, in institute
It states and is uniformly arranged multiple oil-feed ports 31 on the first circumference of inner cavity 35, be uniformly arranged on the second circumference of the inner cavity 35
Multiple oil outlets 32 are uniformly arranged multiple drain taps 33 on the third circumference of the inner cavity 35.The spool 2,
The feedback pin 4 and the spring 5 are sequentially arranged in the inner cavity 35, and the spool 2 can with movement in the axial direction
Make to be connected to and interdict between the oil-feed port 31, the oil outlet 32 and the drain tap 33.The Electrical heads 1 are for when being powered
It is axially moveable the spool 2, and squeezes the feedback pin 4 for being provided with spring 5, in the Electrical heads 1 power-off, the spring
5 make the feedback pin 4 that the spool 2 be driven to reply initial position.
Specifically, under unpowered state, non-electromagnetic-force effect, spool 2 is located at the left lateral position of valve pocket under the action of spring 5
It sets, the oil liquid of oil-feed port position can not be circulated to oil outlet, i.e. output pressure is 0.After Electrical heads partial current, with electromagnetism
Head portion of electrical current increases, and electromagnetic force is gradually increased, and overcomes the spring force of spring 5, pushes spool 2 to move axially to the right, works as valve
When core 2 and valve pocket 3 are in overlapping region (i.e. solenoid valve registration), the pressure oil liquid of oil-feed port circulates to oil outlet.By
Multiple oil-feed ports, oil outlet and drain tap are arranged on inner cavity increases the free air space of oil liquid, makes solenoid valve in the same terms (oil
Fluid viscosity, electromagnetic force) under, it needs the shorter time that can reach desired pressure, the response speed of solenoid valve can be improved.
As shown in Figure 3 and Figure 4, one annular groove 34, institute are set in the position of second circumference of the inner cavity 35
Stating annular groove 34 interconnects multiple oil outlets 32, to increase the free air space of the oil outlet.
Specifically, by the way that corresponding 32 position of oil outlet of valve pocket 3 is carried out out complete cycle opening design, i.e., it is arranged in the position
One annular groove interconnects multiple oil outlets, and increases the flow area of oil liquid, enables oil-feed port oil liquid Fast Filling
To oil outlet rear end cavity, and then pressure is quickly established, increases solenoid valve response speed to reach, oil liquid flow area is as complete
Zhou Zuoyong.The annular groove can substantially increase passage section, to have the function that promote solenoid valve response characteristic.
As shown in figure 4, the opening width of the annular groove 34 is greater than the width of the oil outlet 32.
Further, the section grooves of the annular groove 34 are arc-shaped, so that oil liquid circulation is more smooth.Certainly can also make
With dovetail groove or rectangular channel, specifically it is arranged with being actually needed.
Further, the oil-feed port, the oil outlet and the drain tap are circular hole.It is general so as to external interface
Property.
As shown in Fig. 2, the spool 2 is axis-shaped component, it is interior to be equipped with feedback hole 21, the working oil in the oil outlet 32
When pressing through big, working fluid generates extruding force to the feedback pin 4 by the feedback hole 21, makes the feedback pin 4 is axial to move
It moves to compress the spring 5, and by 33 pressure release of drain tap, and then pushes the spool 2 under opposing spring force effect
It is mobile, to adjust the opening of oil-feed port 31.
Further, the feedback hole 21 is inverted T shaped distribution, when the feedback hole 21 is connected with the oil outlet 31, work
Make oil liquid to flow by the first port and second port of the feedback hole, and passes through the third port stream of the feedback hole 21
Out, to squeeze the feedback pin 4.
Specifically, when Electrical heads are powered, as oil-feed port is persistently opened, pressure persistently increases, in order to maintain corresponding electricity
The pressure value under (electromagnetic force) is flowed, oil outlet position oil liquid is adjusted by being located at the feedback hole 21 that T-type is distributed on spool 2.
Oil outlet pressure oil liquid flows into inside spool 2, acts on feedback pin 4, can not be to the right due to feedback 4 right end valve pocket 3 of pin contact
It is mobile, at this time under the action of feedback force and spring force, it is moved to the left spool 2, the opening of reduction oil-feed port to oil outlet
Size releases pressure from drain tap position.Correspondingly, increasing fuel feeding under electromagnetic force when oil-feed port pressure is relatively low
Mouth openings of sizes makes to export the pressure value that oil-feed port remains more stable, realizes rear end by the self-regulating function of solenoid valve itself
The control of oil circuit.
As shown in Figure 1, the quantity of the oil outlet, the oil-feed port and the drain tap is 4.
Further, further includes: strainer (not shown);The strainer is arranged at the oil-feed port, with filtration
The impurity of oil liquid.
As it can be seen that the present invention provides a kind of electromagnetic pressure control valve for automatic gear-box, it is more by being arranged on valve pocket
A oil-feed port, oil outlet and drain tap, to increase the free air space of working fluid.Existing solenoid valve is solved in gearbox inner fluid
Viscosity great Yi has that response characteristic is low, can improve the response speed of solenoid valve, improves vehicle cryogenic property.
Structure, feature and effect of the invention, the above institute is described in detail according to diagrammatically shown embodiment above
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
