Description
One, technical field
The present invention relates to a kind of ratio pressure solenoid valve open in usual, particularly relate to a kind of ratio pressure solenoid valve of six speed double-clutch automatic transmission systems (6DCT).
Two, background technique
Six speed double-clutch automatic transmission; Be in the technical breakthrough of AMT; Many advantages such as the transmission efficiency of it is integrated MT is high, installing space is compact, cost is low, the deficiency of power interruption when having overcome the AMT gear shift has kept AT, advantage that the CVT shift quality is good; Cancel fluid torque converter direct transmission afterwards in addition and improved transmission efficiency, reduced fuel consume.It improves power character for the energy-saving and emission-reduction of automobile, improves handlingly, and the good result that improves aspects such as Security and gear shift travelling comfort be extensively to approve, is a new high-tech product.
The 6DCT drive system structure is as shown in Figure 1.Two input shafts of 6DCT transmission system are connected with clutch K1, K2 respectively, wherein, and 1,3,5, reverse gear and control via clutch K1; 2,4,6 retainings are controlled via clutch K2.During speed changer work, one of them clutch connection work, the another one clutch breaks off, and the gear that desire is hung engages earlier, and so latter two clutch alternation has guaranteed the continuity of transmission of power, and then improves the shifting comfort of car load.
Hydraulic control system is the core of 6DCT.Provide control signal according to TCU, oil pump provides required pressure, the traffic engineering parameters of power unit such as hydraulic oil passes through to export clutch, gearshift after the hydraulic control system, lubricate.Proportional electromagnetic valve wherein is a pressure controlled valve, and self fuel consumption is little, and consumption systems power is little, is mainly used in the Flexible Control clutch, clutch is combined and separates smooth-going avoiding and impacts, and has improved car comfort, is the critical component in the hydraulic control system.The pressure control pilot valve that the ratio pressure solenoid valve open in usual that the present invention relates to is a hydraulic control system is used for pressure and regulates solenoidoperated cluthes safety valve spool, thereby changes K1, K2 pressure break-make and pressure control thereof, realizes the clutch of K1, K2.
Three, summary of the invention
In order to accomplish above-mentioned purpose, the present invention provides a kind of ratio pressure solenoid valve open in usual, sees accompanying drawing 2.This solenoid valve comprises: valve component 1, and pole shoe member 2, coil housing 3, coil block 4, yoke assembly 5, spring 6, armature component 7, push rod guide holder 8, film 9, steel ball 10, valve seat 11, O shape is enclosed 12 component such as grade.
As shown in Figure 1, oil-feed port connects 0.8mm ± 0.05mm restriction, is connected with the clutch safety valve then, and system provides inlet pressure P to oil-feed port
0, spring 6 is for low rigid spring, when oil-feed port pressure is P
0The time, ball valve is opened under the oil pressure effect, and fluid flows out from oil outlet, and it is 0 (P=0) that the charge oil pressure of clutch safety valve will be unloaded, and ball valve is opened the armature component of steel ball promotion simultaneously and is moved to the left, and spring is compressed; When solenoid valve is switched on; Any given current value I in 0～1A scope, under the electromagnetic force effect, armature component overcomes the suffered hydraulic coupling of steel ball and promotes the steel ball corresponding displacement that moves right; Steel ball and valve base chamber aperture reduce; The oil outlet flow reduces, and sets up pressure between steel ball and throttle orifice, i.e. the pilot pressure P of proportional electromagnetic valve output.In 0～1A current range, electric current increases gradually, and the pressure output control of solenoid valve also approximately linear increases; Electric current reduces gradually, and the also corresponding approximately linear of the pressure output control of solenoid valve reduces, and is as shown in Figure 3; Electric current changes between 0～1A; Pressure output control P changes between P0 and 0, near linear relationship, has the ratio characteristic between electric current and the pressure P.
In this electromagnetic valve structure, adopted basin type electromagnet, like pole shoe member among Fig. 22, yoke assembly 5; Electromagnetic force has the ratio characteristic, and promptly armature component each displacement place in travel range receives the electromagnetic force approximately equal, in this structure; The suffered hydraulic coupling opposite sign but equal magnitude of electromagnetic force and steel ball; Therefore active force and reaction force change the electromagnetic force size through regulating electric current each other, just can change solenoid valve pressure output control size; And electric current and pressure are near proportionate relationship, and therefore this solenoid valve is known as the ratio pressure solenoid valve.
During assembling, by shown in Figure 2,, steel ball 9 is put into valve component 1 with film 9 pole shoe member 2 of packing into; And then valve component 1 pole shoe member 2 is assembled together, the coil housing 3 of packing into is put into coil block 4; Reinstall armature component 7, put into spring 6, reinstall yoke assembly 5; Cover upper O-shape ring 12 closes up at last, has just formed ratio pressure solenoid valve shown in Figure 2.
This valve has following structure characteristic:
1, uses fexible film to support between valve component and pole shoe member, can make in the electric current adjustment process armature component motion mild, improved the stability of motions of armature component, and avoided the impact of hydraulic oil, thereby reduced the pressure diagram fluctuation armature component.(see figure 4).
2, magnetic isolating pad and guide holder integral type design; With two Element Designs is a part push rod guide holder 8; Improved the stationarity in the armature component movement process, having eliminated armature component free-standing magnetic isolating pad in movement process influences it, reduces pressure diagram fluctuation (see figure 5).
3, the push rod guide holder is packed into behind the pole shoe, adopts the closing in mode (see figure 5) of riveting tightly, and adopts Spielpassung between push rod guide holder and pole shoe, can prevent that push rod guide holder endoporus from producing variation because of assembling the back.
4, adopt coil block endoporus location pole shoe member, yoke assembly, guarantee the two ends coaxality, reduce the armature component kinetic force of friction, improve the pressure controling precision (see figure 6) of solenoid valve.
5, coil block coil carrier endoporus star structure design more helps coil inside heat radiation (see figure 7).
6, bolt-type coil Placement, easy to connect, reliable (see figure 7).
