Description
Technical field
This utility model belongs to technical field of hydraulic elements, specially insert high-flow threeway proportional pressure-reducing valve, mainly
Crash change of speed for automatic gear-box and the smooth engagement of clutch.
Background technology
The change speed gear box of engineering truck is experiencing to be changed to self-shifting from hand gear, and widely used technology is all
Power shifting automatic gear-box.The executive component of power shifting is exactly the solenoid directional control valve of two-position three way, by solenoid
Power on/off realizes switching on and off of oil circuit, thus controlling the action of gearshift.Power on/off due to solenoid directional control valve is out
Pass action, reflects in actuator to be exactly the standard-sized sheet of oil circuit and state of entirely breaking it may appear that than larger hydraulic shock.
For improving this hydraulic shock, occur in that now a kind of pilot proportional air relief valve of threeway.This threeway pilot-operated type
The flow-rate ratio of proportional pressure-reducing valve is larger, up to 25L/min, when given peak point current, can quickly rub to clutch
Pad chamber punching oil, then control electric current starts to gradually rise from minimum again, and proportional lifting rubs the pressure of piece chamber, realizes rubbing
The smooth engagement of pad, thus realize flexible shifting.This proportional pressure-reducing valve is pilot-operated type structure, and primary valve part is designed with diameter very
Little guide's oilhole, is easy in actual use be blocked and lost efficacy.
Utility model content
This utility model is directed to prior art deficiency, provides insert high-flow threeway proportional pressure-reducing valve, this kind of plug-in type
Big flow threeway proportional pressure-reducing valve can by adjust electric current come the pressure of adjustment work mouth, and make this valve have logical
Antifouling property is improve while oily ability is big.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals：Insert high-flow
Threeway proportional pressure-reducing valve, including valve pocket, is inserted with valve element in described valve pocket, and described valve pocket one end is provided with spring base, described bullet
It is provided with the first through hole connecting oil circuit in the middle part of spring abutment, described valve pocket is provided with the first radial hole for connecting hydraulic fluid port and the
Two radial holes, described valve element includes valve element front end and valve element rear end, is provided with multiple between described valve element front end and described spring base
Position spring, described valve element rear end connects push rod, described valve element front end is provided with the first passage connecting described first through hole, institute
State first passage side wall and be provided with the 3rd radial hole, between described valve element rear end and described valve pocket, be provided with differential sleeve, described differential
Form confined space, described confined space passes through damping hole and described first passage between set and described valve pocket and described valve element
Connect, be arranged with outside described push rod and determine ferrum, described push rod is connected with electromagnetic actuator device.Described first radial hole connects once
Pressure port, described first through hole connecting secondary pressure port, that is, the operating pressure mouth after reducing pressure, the second radial hole connects oil return opening,
During electromagnetic actuator device no power, back-moving spring promotes valve element the 3rd radial hole to be connected so that work pressure with the second radial hole
The direct oil return of power mouth；During electromagnetic actuator device is energized and electric current is gradually increased to maximum current, electromagnetic actuator device
Promote valve element movement until maximum displacement, the displacement of valve element make after the 3rd radial hole and the disconnection of the second radial hole with the first footpath
To hole connection, pressure port is connected with working hole, the pressure oil of working hole passes through first passage and enters from damping hole
Sealed volume, the pressure oil of such working hole just acts directly on valve element rear end, and valve element front end is just simply played guiding and connected
The function of oil circuit, does not produce oil pressure.The oil pressure of working hole acts on valve element front end, produces the oil pressure contrary with electromagnetic force,
This oil pressure and electromagnetic force interact, you can control the output pressure of working hole, and output pressure can control with electric magnet
The linearly increasing and linear reduction of electric current, working hole pressure is also with linearly increasing and linear reduction, straight due to valve element rear end
Footpath is smaller, so the oil pressure producing is also smaller, in requisition for electromagnetic force also just smaller, so electromagnetic actuator device
Volume smaller.The valve element front end logical oil passage larger because diameter can be arranged greatly, therefore oil filling capacity relatively strong it is not easy to
Blocking.
It is preferred that described electromagnetic actuator device includes the dynamic iron component connecting described push rod in technique scheme, described
Dynamic iron component is determined to be provided with plunger tube outside ferrum with described, is provided with solenoid, described dynamic iron component outside described plunger tube
End is provided with antifreeze plate, is provided with yoke piece, described antifreeze plate, described yoke between described antifreeze plate and described solenoid
Piece, described solenoid and described determine to be provided with shell outside ferrum.
It is preferred that described determine ferrum outer ring and be provided with pressing plate in technique scheme, described pressing plate is provided with installing hole.
Setting pressing plate facilitates the installation of this proportioning valve.
It is preferred that being provided with some sealing rings outside described valve pocket in technique scheme.
It is preferred that being arranged with filter screen on described second radial hole in technique scheme.Setting filter screen can carry further
High contamination resistance.
This utility model compared with prior art, has the advantages that：This kind of insert high-flow threeway ratio subtracts
Pressure valve can by adjust electric current come the pressure of adjustment work mouth, and make this valve have oil filling capacity big while carry
High antifouling property.
