In embodiment, Fig. 1 and Fig. 4 are referred to, the tail accent of 1 valve chamber 1a of valve body of the invention is pressed with energy through plastic-sealed body 3 Play the role of diamagnetic copper seat 24, the center of the copper seat 24, which processes promising mandril 23 and slides axially, to be provided the copper seat of guiding role and lead Hole 24a, and the oilhole 24b using the lubricious mandril of hydraulic oil 23 is machined on copper seat 24, it is equipped with and pushes up in plastic-sealed body 3 Bar 23 slides the tip-lever support 25 for wearing cooperation.Copper seat 24 is the innovative point again of the present invention, is designed with copper base structure in this way to mandril 23 can play good guiding role, but also have good diamagnetism.
As depicted in figs. 1 and 2, on the peripheral surface of strainer connector 5 of the invention relatively close front end be machined with annular it is close Groove 51 is sealed, be installed in the annular seal grooves 51 prevents the of hydraulic fluid leak after being installed with speed changer valve plate plug-in type One sealing ring 61, relatively close rear end is machined with annular channel 52 on the peripheral surface of strainer connector 5, pacifies in the annular channel 52 Equipped with the second sealing ring 62 for preventing hydraulic fluid leak after being installed with speed changer valve plate plug-in type.The periphery of strainer connector 5 The opening of sieve communicated with P mouthfuls is additionally provided on face, the front end face of strainer connector 5 is then designed with the opening of sieve communicated with A mouthfuls, filter Net design is in opening of sieve, to prevent the impurity in hydraulic oil from entering in valve body.First sealing ring 61 and the second sealing ring 62 are protected The leakproofness of automatic gear-box solenoid valve assembly is demonstrate,proved.
In embodiment, electromagnetic coil assembly 4 of the invention includes coil case 41, electromagnetic coil 42,43 and of dynamic iron core group Static iron core 44;Coil case 41 forms the center stepped hole 41a in center and the annular assembly around center stepped hole 41a Chamber 41b, electromagnetic coil 42 are fixedly mounted in annular assembly cavity 41b, and dynamic iron core group 43 is slidingly arranged at center stepped hole 41a In, static iron core 44 is fixedly mounted on the front end of coil case 41.
The front end face of static iron core 44 and the liquid-tight envelope in rear end of plastic-sealed body 3 are connected to a fixed, the center processing of the static iron core 44 There is the slide opening for making the liquid-tight envelope of the tail end of mandril 23 slide through, rear end face and the dynamic iron core group 43 of mandril 23 are detachable phase top It connects.
Iron core group 43 is made of thick mandril 431, preceding spring 432, rear spring 433 and dynamic iron core 434;Dynamic iron core 434 is fixed It is sleeved on thick mandril 431, the leading portion and back segment of the thick mandril 431 extend dynamic iron core 434, and preceding spring 432 is sleeved on slightly The leading portion of mandril 431, rear spring pocket 433 are mounted in the back segment of thick mandril 431, the rear end face of mandril 23 and 431 front end face of thick mandril The bottom surface phase apical grafting for the positioning shrinkage pool 43a being formed with.
The mandril 23 of the present invention is detachable design structure with thick mandril 431, thus is avoided that between them in the added-time It is required that therefore the high problem of concentricity reduces the precision of product processing, reduces processing cost.
The present invention can generate electromagnetic force after the energization of electromagnetic coil 42, and the electromagnetic force is in iron core group 43 so as to band Dynamic mandril 23 moves.
Dynamic iron core 434 is fixedly set in such a way that aluminium backing 435 and thick mandril 431 are interference fitted on thick mandril 431, The front end of preceding spring 432 and 44 phase apical grafting of static iron core, the rear end of the preceding spring 432 is contacted with aluminium backing 435 to be matched, zone center The tail mouth of rank hole 41a is provided with the rear spring seat 45 of 433 preload pressure of adjustable rear spring, the front end of rear spring 433 and thick top The rear end of the bottom surface phase apical grafting of the spring eye of bar 431, the rear spring 433 is matched with 45 apical grafting of rear spring seat.The present invention can be with The preload pressure of spring 433 after being adjusted by rear spring seat 45, to reach the pressure for adjusting unidirectional hydraulic fluid port 1b and opening or closing Size.The present invention is equipped with spring in the both sides of both ends, that is, dynamic iron core 434 of thick mandril 431, in this way to the movement energy of dynamic iron core Play the role of buffering, and this structure enables the noise of this valve to reduce.
The rear end of electromagnetic coil 42 connects the inserted sheet 46 that promising electromagnetic coil 42 provides power supply, and the rear end of coil case 41 is set Promising inserted sheet 46 provides the socket cover 47 of protection.
The automatic gear-box solenoid valve of the present invention is a kind of switch electromagnetic valve open in usual, when 42 no power of electromagnetic coil, Mandril 23 is moved to the left through spring 432 before the promotion compression of thick mandril 431 under the effect of rear spring 433 and pushes steel ball 21 open, make unidirectional Hydraulic fluid port 1b is opened, and is connected between P mouthfuls and A mouthfuls, after electromagnetic coil 42 is powered, after dynamic iron core 434 is compressed by the effect of electromagnetic force Spring 433 moves right, and so that mandril 23 is moved right and closes unidirectional hydraulic fluid port 1b, the channel between P mouthfuls and A mouthfuls of cut-out is played one and opened The effect for closing oil circuit, to realize control clutch.
The configuration of the present invention is simple, service life is long, low to part processing precision requirement, and stability is good and can realize fast quick-mounting Match, is used especially suitable for the fast automatic gear-box of BMW 6.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not It can depart from the scope of the present invention.
