Description

The guiding valve that particularly in automatic gearbox, uses
Existing technology
The present invention relates to a kind of guiding valve.
Background technique
On market, be disclosed in the magnet valve of the electricity operation in the automatic transmission of automobile, particularly so-called pressure regulator valve (guiding valve).Therefore can directly control the clutch of automatic transmission.Allegedly some valves can be worked on relative dynamic ground on the one hand like this, and can produce big hydraulic pressure stream at short notice.Be stable with respect to interference parameter on the other hand with insensitive.
The pressure regulator valve of current form of implementation comprises the actuator that is used to operate spool.Said spool can be operated hydraulic unit.Said hydraulic unit has for example input adapter, one or more outflow joint and at least one working joint.Said working joint is connected with backflow fittings hydraulic pressure through outside hydraulic pipe, and the hydraulic pressure reflux line for example extends on a so-called control panel, and is used for working pressure is turned back to the control room adjacent with spool.
The ground work of the for example following mode of pressure regulator valve: when electromagnet no current (affiliated) spring moves to first end position together with spool and armature when the actuator no current state.Working joint is connected with outflow joint hydraulic pressure in this position.Therefore, close the high joint of pressure valve no current, perhaps do not have pressure (English: " normally closed " or " NC ").Armature and spool overcome spring force ground through magnetic force and move along second end position when electromagnet has electric current to flow through.At first working joint separates with outflow joint hydraulic pressure during valve core movement, and and then working joint is connected with the inflow joint.At this moment the propagation of pressure that on the inflow joint, exists is to working joint.Return joint because the pressure on working joint increases to be delivered to through hydraulic tubing, thus guiding valve with return the control room (return chamber, FB chamber) that joint is connected in the same pressure of formation.This pressure applies a kind of to the acting pressure of actuator to spool.When this pressure and spring force surpass the magnetic force of magnet together, then this spool axially and for example this place move, promptly flow into joint and more and more take off coupling, perhaps even separate with working joint.Be a side consequently, and magnetic force equilibrium of forces occur between the opposing party at spring force and hydraulic pressure.Can be adjusted in the pressure that exists on the working joint according to flowing through current of electromagnet to a great extent in such event.
The patent publication of this professional domain for example is DE 10 2,008 042 624 A1.
Summary of the invention
Problem of the present invention is through being able to solution according to the described guiding valve of claim 1.In the dependent claims some favourable improvement projects are illustrated.Find important for the present invention characteristic in specification that in addition also can be below and the accompanying drawing, wherein, these characteristics are to use separately or the use of various combination ground all is important for the present invention, need not spell out once more about this point.
Have following advantage according to the method for the invention, promptly guiding valve, particularly pressure regulator valve can be used in the automatic gearbox, and when working joint was connected with inflow joint hydraulic pressure, said automatic transmission had short especially step response time.So just can be fast and the clutch of operational example such as automatic transmission reliably.
The present invention considers, such guiding valve has-usually eletromagnetic-operating-actuator.This actuator can load to spool at first direction.In addition, the pressure that in the control room, exists can load to spool in the second direction opposite with first direction.In this case, guiding valve so designs as pressure regulator valve, can between this side of actuator and the opposing party through the axial force that pressure produced in the control room, equilibrium of forces occur.That a kind of power that the back is mentioned obtains the support of the power of valve spring usually.Therefrom the axial force according to actuator produces desirable pressure adjusting on working joint.
On this basis, the present invention is with the following starting point that is thought of as, that is, the effect to actuator when the pressure in the control room is high more limits, and on the contrary, the effect to actuator when the pressure in the control room is low is more supported.Therefore on the off-take point of the flow channel of guiding valve, divide to pick out a hydraulic pressure, and it is transported to the control room.Therefore, in order to open hope apace alap pressure is arranged at least at short notice in the control room., off-take point is arranged in the zone in the space of in axial direction extending of the spool that flows between joint and the working joint, wherein, this space has formed described flow channel basically for this reason.
When spool be in the corresponding position or motion in when flowing into joint hydraulic pressure being connected each other with working joint; Hydraulic pressure at off-take point is lower; Wherein, in flow channel, at least temporarily produce the lower strong hydraulic flow of one its hydrostatic pressure ratio.This effect for example is derived from water jet pump, also is celebrated with " suck and spray effect ".This low pressure is input to the control room.In other words, supported the opening stage of valve core movement through the lower pressure that in the control room, occurs in the meantime, like this, guiding valve just can produce high hydraulic pressure apace in working joint.So-called " step type response time " is correspondingly little, and the dynamic of guiding valve is correspondingly big.
When and then flowing into joint and have identical hydraulic pressure with working joint, the mobile disappearance in the flow channel, perhaps littler at least, and the control room can receive the pressure of working joint substantially, and therefore the adjusting of desirable pressure is made contributions.Yet as long as require again to improve pressure, this can have high dynamic.
Certainly, as long as the hydraulic pressure on " inflow joint " is higher than the pressure on " working joint " when having at least, described joint just can be the hydraulic joint arbitrarily with guiding valve of any function.
A scheme regulation of guiding valve is arranged on the passage of off-take point to the control room in the housing of guiding valve.That is to say that this passage road forms the Returning pipe between flow channel or off-take point and the control room.Little through what can make possible leakage keep especially in the housing that this passage is arranged on guiding valve.Improved the function of guiding valve through this measure.Off-take point is fixed the position with respect to the housing of guiding valve.
Another program regulation of guiding valve is arranged on the passage from the off-take point to the control room in the spool.Like this, this passage just can be simple especially, and flow imaging advantageously designs.Also can leakage be minimized.In addition, the expense that also can lack is transformed into the valve design in past according to guiding valve of the present invention.Off-take point is a fixed-site with respect to spool.
Another program of guiding valve regulation will the passage from the off-take point to the control room be arranged on the outside of the housing of guiding valve.For example this passage is formed on the hydraulic control plate of automatic transmission, can reduce the manufacture cost of guiding valve through this measure.
Stipulate that additionally the end segments that is not used in passage at least one hole is blocked by a spheroid.Like this, just simply mode is by the hole formation of axial and radial for this passage, and wherein, these obsolete end segments hydraulically seal through at least one spheroid.Like this, guiding valve has just become cheaply.
When the wall section that when fluid flow into working joint from flowing into joint, forms space and/or and this opposed housing in space, then can improve the dynamic characteristic of guiding valve for the purpose that makes the minimize pressure on the off-take point.For this reason, the hydraulic pressure professional domain discloses certain methods.For example through analog computation in guiding valve or the hydraulic pressure and the flowing velocity that in the space, occur, and make the geometrical shape optimization of guiding valve through this measure.The purpose of these simulations can be to make the hydrostatic pressure that on off-take point, produces minimize (" low pressure "), and particularly flowing into the dynamic maximization that correspondingly makes guiding valve during generation hydraulic pressure connects between joint and the working joint.
A scheme regulation of guiding valve is not flowing into generation hydraulic pressure connection between joint and the working joint when electromagnet has electric current to flow through.Instead regulation is not flowing out generation hydraulic pressure connection between joint and the working joint when electromagnet has electric current to flow through.Do not flow through when electromagnet has electric current, spool did not move to respectively in the corresponding axial position by the power of valve spring when perhaps actuator had activation, and remained there.Like this, the present invention may be used on the guiding valve of automatic transmission, perhaps in the different basic form of implementation of hydraulic controller.In addition, the present invention also may be used on having and becomes section ground " rising " perhaps to become in the characteristic guiding valve on section ground " decline " at least at least.

Embodiment
Fig. 1 illustrates the guiding valve 5 of the clutch device that is used for the hydraulic operation automatic gearbox.Guiding valve 5 comprises housing 6.On this housing, in the right areas of figure, be provided with actuator 8, said actuator is designed to electromagnet 8 at this.In addition, guiding valve 5 comprises that also other does not have the shell section 7 of detailed description at this.Guiding valve 5 is around longitudinal shaft 15 rotation symmetric designs with those parts that belong to guiding valve 5 basically.
Electromagnet 8 comprises coil 9 and armature 10.Said armature can be attracted to the left side by the pole core in the picture 11 when electric current flows through coil 9.Armature 10 is arranged in the housing 6 by coupling unit 12 and 13 and one of coupling pins, and moving spool 14 couplings of axially-displaceable.Said spool 14 shown in the centre of picture and the left area in axial neutral position.Arrow 16 expressions first axial direction, arrow 18 expressions second axial direction.
Spool 14 have a radial ring of in axial direction extending around, and it is shaped as the space 20 of the contraction of branch gradient.Alternatively can be connected by this space working joint A with flowing into joint P or flowing out joint T hydraulic pressure.Flow into joint P, working joint A and flow out joint T and be connected with 26 hydraulic pressure with the doughnut 22,24 that in housing 6, forms respectively.Yet these joints can not be clear that in the sectional view shown in Fig. 1.Some possibly flow through the direction of the flow of pressurized of these joints arrow 30,31 and 32 expressions.In the inner radial section of housing 6, form a flow channel 34 by this space 20.In addition, guiding valve 5 also comprises two outflow joint T1 and T2 that are used to discharge leakage.
The doughnut in picture left part zone of guiding valve 5 forms a control room 36.In addition, this control room 36 also receives the restriction of pressure surface (no reference character) of spool 14 on the left side and the right of the circular groove 37 that in picture, is arranged in the spool 14.The pressure surface on the right is bigger than the pressure surface on the left side.
This control room 36 also has off-take point 38 hydraulic pressure of a radial hole (not having reference character respectively) and flow channel 34 to be connected through a radial hole, an axial bore of housing 6.Said off-take point 38 is seen to be arranged on along the axial direction of spool 14 in the zone in space 20 and is flowed between joint P and the working joint A.These radial holes and axial bore form a passage 40 together, and block by a spheroid hydraulic seal respectively in their obsolete end segments.Said axial bore is that the space 44 through housing 6 forms.
The end segments on the picture left side of spool 14 is loaded to the right in picture by a valve spring 46.Said valve spring 46 is supported on the end segments that is pressed into 48 of housing 6.In a word, owing to passage 40 is integrated in the housing 6, so the leakage of the guiding valve 5 of Fig. 1 is smaller.For fluid from flowing into joint P and flowing into the minimized purpose of hydrostatic pressure that makes the flowing of working joint A on off-take point 38 and will be in the space shown in Fig. 1 20 and housing 6 with its opposed wall section optimization.
Spool 14 does not move right in picture (arrow 18) through the power of valve spring 46 when electromagnet 8 has electric current to flow through, and wherein, working joint A and doughnut 26 perhaps flow out joint T hydraulic pressure and connect.Flow out joint T and perhaps do not have only lower hydraulic pressure.Therefore the pressure on working joint A is also low.That is to say that guiding valve 5 cuts out when no current state.
When electromagnet 8 had electric current to flow through, armature 10 was inhaled to the left side (arrow 16) by pole core 11 in picture through magnetic force.Coupling pin 13 is delivered to spool 14 with this power, and this spool is towards the direction motion of arrow 16 then.As long as flow channel 34 is connected with annular space 22 hydraulic pressure, then produce from flowing into the hydraulic flow of joint P towards working joint A.Flowing into joint P has than higher hydraulic pressure.Correspondingly the flowing velocity in taking-up place 38 is high, and hydrostatic pressure is low, so the hydrostatic pressure in the passage 40 also correspondingly is low.
The low pressure that in passage 40, exists is delivered to control room 36.Because be arranged on the pressure side of the pressure side on circular groove 37 the right in the picture,, supported the effect of electromagnet 8 through this measure so be created on the picture synthetic power left there greater than the left side.Spool 14 quickens towards the speed of direction 16 motions in this way, and working joint A can be connected with inflow joint P with the large-section especially soon, just opens guiding valve 5 apace.Guiding valve 5 is as pressure regulator valve operation in this state, wherein, is that the magnetic force of a side and electromagnet 8 is equilibrium of forces can occur between the opposing party in the power of valve spring 46 with through the axial force that the pressure in control room 36 produces.
Fig. 5 is illustrated in the situation that the step type of the pressure 60 on the working joint A of guiding valve 5 is replied.Shown in system of coordinates vertical put on pressure 60 and the electric current 1 that flows through coil 9 be shown.Abscissa express time t.The rating value of first dotted line, 62 expression electric currents 1, the rating value of second dotted line, 64 expression pressure 60.Shown in Figure 5 is the time graph of the hydraulic pressure in the actuator that is described in the clutch of automatic transmission.
Reinstate electric current 1 through coil 9 from moment t1.After the dead time finishes moment t2 pressure 60 jump types rise to first numerical value 66, and constantly be increased to second value 68 up to moment t3 pressure then.Moment t3 pressure 60 jump types rise to rating value 64.The time lag between t1 and the moment t3 is called " the step type response time " of guiding valve 5 constantly.
Reach the rating number 64 of pressure 60 from moment t3, wherein, the flow of pressurized in flow channel 34 disappears basically.Pressure in the passage 40 then, and correspondingly the pressure in the control room 36 is roughly the hydraulic pressure on the working joint A.Like this, guiding valve 5 just can be according to disclosed mode, the pressure of regulating on the working joint A according to the electric current that flows through coil 1 according to the type of pressure regulator valve.
Fig. 2 guiding valve 5 is shown with the second similar form of implementation of Fig. 1.With Fig. 1 difference be that the doughnut 52 that holds valve spring 46 has radially enlarged, like this, the axial bore of passage 40 (not having reference character) just can pass through doughnut 52 pore-formings.Therefore space 44 is just optional.Housing 6 is correspondingly suitable with end piece 48.The functional part of the guiding valve 5 of Fig. 2 and Fig. 1's is identical.
Fig. 3 shows a kind of form of implementation of guiding valve 5.In this form of implementation, 36 passage 40 is arranged on the spool 14 from off-take point 38 to the control room.Sectional view at spool this illustrate 14.Control room 36 is connected through two radial holes of spool 14 and off-take point 38 hydraulic pressure of an axial bore (not having reference character respectively) and flow channel 34.That is to say that radially hole and axial hole form passage 40 together.With Fig. 1 and Fig. 2 difference be that off-take point 38 is parts of spool 14, therefore and can move with it.At this, this off-take point 38 is designed to radially be arranged on the tubular member 54 on the spool 14.Remittance mouth through this measure off-take point 38 or tubular member 54 can be arranged on the inside wall section in a footpath of housing 6 more hermetically.
Be the sectional view of so selecting housing 6 in Fig. 3, can see to form the passage (no reference character) that flows into joint P, working joint A and flow out joint T.Other parts of guiding valve 5 are similarly perhaps identical with the corresponding parts of Fig. 1, Fig. 2.
Fig. 4 illustrates a kind of form of implementation of guiding valve 5, and 36 passage 40 is arranged on the outside of the housing 6 of guiding valve 5 to the control room from off-take point 38 in this form of implementation.This passage 40 is connected with control room 36 or flow channel 34 with 58 through radial tab 56.This passage 40 for example can be the passage in the control panel of automatic transmission, or the hydraulic tubing of a separation.Other parts of guiding valve 5 are similar or identical with the corresponding parts among Fig. 1 or Fig. 2.
Is more such guiding valves 5 at Fig. 1 to the form of implementation described in Fig. 4, and promptly these guiding valves are " no current is closed ", that is to say, working joint A is that hydraulic pressure separates with flowing into joint P when electromagnet 8 has electric current to flow through.Yet for example through flowing into joint P and the transposing of flowing out joint T, and the variation of the layout of transformation through space 20 and off-take point 38 also can be designed to " no current is opened " with guiding valve 5.Wherein, working joint A is connected with inflow joint P hydraulic pressure when electromagnet 8 does not have electric current to flow through.Yet this point does not illustrate in Fig. 4 at Fig. 1.
