By hierarchical design, first can not consider the design of oil duct somewhere throttle orifice, decrease the workload of chip component layout design.By each module placed opposite, position relationship is easily determined, makes design become simply corresponding, greatly reduces the difficulty of global design.Simultaneously by hierarchical design, the redundant space in integrated bulk can be compressed, reach volume minimum.
3rd step, carrier ring functional hole designs
In the hierarchical design of layout, hole on the space bar 805 that oil duct between upper valve body 808 with main valve body 804 can pass through realizes being communicated with, during as restriction relation in lower floor's (accompanying drawing 7) of valve body in design and main valve body between physical layer (as Fig. 4) input and output, the oil groove open with physical layer (as Fig. 4) on main valve body to lower floor's (accompanying drawing 7) of hole and upper valve body is needed to carry out Seal Design.Functional hole design is as follows:

After above-mentioned drill way layout completes, remaining part is sealing surface, and as shown in Figure 10, by above-mentioned design, the carrier of each functional hole is not only by known dividing plate, can also play the effect of sealing.
Finally, supplementary module design
After layout and cloth hole have been designed, because the two sides of valve body has been designed, also namely an integrated block designing completes, and now needs the supplementary module of system to focus on as much as possible in the middle of integrated package.
The supplementary module of this hydraulic control system only has the pilot control hydraulic accumulator D7 of pilot-actuated valve D5.Need the oil pressure of pilot control end in bilateral throttle slide valve D6 be incorporated in the middle of pilot control hydraulic accumulator D7, the peak value that effective reduction pilot-actuated valve D5 output oil pressure impacts, absorb pressure pulsation when pilot-actuated valve D5 does, pilot-actuated valve D5 oil pressure is exported more steady.As shown in Figure 11, pilot control hydraulic accumulator D7 is spring loaded accumulator, and pilot control hydraulic accumulator D7 is arranged in upper valve body 808, and its filler opening is in physical layer 502 place under upper valve body, and 603 is auxiliary hole when installing pilot control hydraulic accumulator D7; As can be seen from accompanying drawing 6, pilot control hydraulic accumulator D7 filler opening position 502 is near the oil pressure output terminal 415 of pilot-actuated valve D5.The oil duct in layout design can not only be avoided like this.And the oil pressure that pilot-actuated valve D5 can be made to export is shorter to the oil duct distance of pilot control hydraulic accumulator D7, make pilot control hydraulic accumulator D7 to the wave motion response of pilot-actuated valve D5 output oil pressure than very fast.
Involved hydraulic control system hydraulic control module explosion figure just can be obtained as shown in figure 12 according to flow process Figure 13 and above-mentioned several steps.Comprising: main oil pressure pressure regulator valve spring end cap 801, main control oil pressure pressure regulator valve spring end cap 802,803 is main control oil pressure pressure regulator valve spring, main control oil pressure pressure regulator valve spool 212, main valve body 804, dividing plate 805, oil extraction back pressure valve spool 206, oil extraction back pressure valve spring 806, oil extraction back pressure valve spring end cap 807, main oil pressure feedback control valve D8, upper valve body 808, bilateral throttle slide valve D6, pilot-actuated valve D5, pilot control hydraulic accumulator D7, main oil pressure pressure regulator valve spool 201, main oil pressure pressure regulator valve spring 809.
Below, the working procedure of hydraulic control module of electrohydraulic control system of the present invention is described in conjunction with Fig. 1-2.During work, start pump D0, through oil pump flow out high-pressure oil flow through main oil pressure pressure regulator valve D1, because main oil pressure pressure regulator valve spool 201 is designed to step type, main oil pressure acts on main oil pressure pressure regulator valve spool 201 step surface at feedback end 205 place, main oil pressure pressure regulator valve spool 201 top, and the oil pressure that main oil pressure feedback control valve D8 exports acts on the step surface of main oil pressure pressure regulator valve spool 201 at feedback end 204 place.When needing different main oil pressures, only need adjust the size of main oil pressure feedback control valve D8 output oil pressure, the oil pressure that such main oil pressure pressure regulator valve D1 spool 201 step surface acts on is different, main oil pressure pressure regulator valve spring 809 is also just different by the value compressed, varying in size of main oil pressure pressure regulator valve spool 201 flow-off (in Fig. 2 203), just can realize different main oil pressures.Through the main oil pressure that main pressure regulator valve modulates, one road flows to shown in inlet opening 412(Fig. 4 of bilateral throttle slide valve D6), one road flows to shown in inlet opening 211(Fig. 2 of main oil pressure pressure regulator valve D1), by main control oil pressure pressure regulator valve, the main control oil pressure modulated flows to electromagnetic valve guide control valve D5 respectively, main oil pressure feedback control valve D8 oil-feed port 401, shown in 405(Fig. 4), electromagnetic valve guide control valve D5 is energized, export certain oil pressure, thus promote the effect that bilateral throttle slide valve D6 overcomes spring force, bilateral throttle slide valve D6 is made to export different oil pressure, to realize the control of clutch C0 pressure.
When not working, start pump D0, through oil pump flow out high-pressure oil flow through main oil pressure pressure regulator valve D1, main oil pressure acts on bilateral throttle slide valve inlet opening 412 place (shown in Fig. 4), electromagnetic valve guide control valve D5 no electric circuit, bilateral throttle slide valve D6 does not move, oil pressure delivery outlet 403 place of bilateral throttle slide valve is communicated with bilateral throttle slide valve return opening 409 place, and return opening 409 place is communicated with inlet opening 215 place of oil extraction back pressure valve, oil-feed port 403 towards clutch now bears the passage of clutch oil extraction, and namely now clutch C0 pressure is the pressure of the oil extraction back pressure of setting.
As can be seen from such scheme, because the present invention can to simplify the design process of hydraulic control module by above four steps, shorten the lead time; Effectively can also utilize the space of integrated valve block simultaneously, reduce valve block and amass; Additionally by the mode increasing dividing plate, functional hole is arranged on dividing plate, can reduces in valve body or the difficulty of hole design, processing between valve body.
