Abstract
The utility model is related to a kind of double-clutch speed changer High-speed on-off control valves, including valve body (4) and positioned at the internal spool (3) of valve body (4), oil return opening (5) and oil inlet one (6) are provided with above valve body (4) shell, the spool (3) is located under centralizing spring (2) effect in the middle part of valve body (4), the oil return opening (5) and oil inlet one (6) are blocked in the end at its both ends respectively, so that oil return opening (5), oil inlet two (7) below oil inlet one (6) and valve body (4) shell is not connected, using three-way pressure reducing valve decompression speed per hour can be overcome to spend the shortcomings that slow.When secondary pressure is excessively high, it can the direct oil return box in another main channel through three-way pressure reducing valve.The threeway proportional pressure-relief valve control pressure rise or fall time is essentially identical.The constant pressure system of holding is kept when being moved available for piston two-way.
Description
Technical field
The utility model is related to automotive transmission fields, are specifically a kind of double-clutch speed changer High-speed on-off control valve.
Background technology
The input unit of proportional pressure-reducing valve is electromechanical converter, and the electric signal of input is converted into mechanical quantity by it.Conversion
Device has the forms such as servomotor and stepper motor, force motor and torque-motor, proportion electro-magnet.But common proportioning valve is mostly adopted
With proportion electro-magnet, proportion electro-magnet is designed according to electromagnetic principle, the mechanical quantity (power or torque and displacement) that can generate it
It is proportional to the size of input electrical signal (electric current), then the position of hydraulic pressure valve core is continuously controlled, and then realize and continuously control
Pressure, direction and the flow of hydraulic system processed.But existing control valve boosting, dip time be not equivalent, causes control performance cannot
Meet increasing requirement.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of double-clutch speed changer High-speed on-off control valve, with
Solve defect in the prior art.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of double-clutch speed changer High-speed on-off control valve, including valve body (4) and positioned at the internal spool of valve body (4)
(3), oil return opening (5) and oil inlet one (6) are provided with above valve body (4) shell, the spool (3) is in centralizing spring (2)
Effect is lower to be located in the middle part of valve body (4), and the oil return opening (5) and oil inlet one (6) are blocked in the end at both ends respectively so that oil return
Oil inlet two (7) below mouth (5), oil inlet one (6) and valve body (4) shell is not connected；Have outside the valve body (4) than
Example electromagnet (1) is fixedly connected by connecting shaft with spool (3)；
Further, proportion electro-magnet (1) series resistor, for improving dynamic property；
The beneficial effects of the utility model are：Using three-way pressure reducing valve decompression speed per hour can be overcome to spend the shortcomings that slow.
When secondary pressure is excessively high, it can the direct oil return box in another main channel through three-way pressure reducing valve.Threeway proportional pressure-relief valve control pressure
The power rise or fall time is essentially identical.The constant pressure system of holding is kept when being moved available for piston two-way.
Description of the drawings
Fig. 1 is the utility model structure diagram；
In attached drawing, parts list represented by the reference numerals is as follows：
1st, proportion electro-magnet, 2, centralizing spring, 3, spool, 4, valve body, 5, oil return opening, 6, oil inlet one, 7, oil inlet two.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of double-clutch speed changer High-speed on-off control valve, including valve body (4) and in valve body (4)
The spool (3) in portion, valve body (4) the shell top are provided with oil return opening (5) and oil inlet one (6), and the spool (3) is in
Spring (2) effect is lower to be located in the middle part of valve body (4), and the oil return opening (5) and oil inlet one (6) are blocked in the end at both ends respectively,
So that the oil inlet two (7) below oil return opening (5), oil inlet one (6) and valve body (4) shell is not connected；The valve body (4) is outside
There is proportion electro-magnet (1) to be fixedly connected by connecting shaft with spool (3) in portion；
Further, proportion electro-magnet (1) series resistor, for improving dynamic property；
Operation principle：When spacing current, spool is in middle position under centralizing spring effect, and each hydraulic fluid port is not connected.
When proportion electro-magnet galvanization, corresponding electromagnetic force moves to right spool, connects oil inlet one, oil inlet two.Oil inlet is second-rate
The fluid gone out spills out executive component and completes set work, and makes pressure rise.This pressure feeds back to valve through inner passage simultaneously
End applies a power opposite with electromagnetic force and acts on spool.When the pressure of oil inlet two is enough balanced electromagnetic power, guiding valve
Return to middle position.At this moment the pressure p A of oil inlet two is remained unchanged, and proportional to electromagnetic force.If the power that pA applies spool surpasses
Electromagnetic force is crossed, spool moves on to the left side, and oil inlet two, which connects oil return opening, declines pressure, until new balance re-establishes.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modifications, equivalent replacements and improvements are made should be included in the guarantor of the utility model
Within the scope of shield.
