Under, fluid can be caused to enter the first control terminal 17A1 of the first mechanical slide valve 17 by the first control magnetic valve 19, so that
The oil inlet 17P and oil-out 17B for obtaining the first mechanical slide valve 17 are communicated, so as to which fluid can reach oil-out from oil inlet 17P
17B, subsequently into first clutch 13, so as to promote first clutch 13 to realize engagement；As a same reason, the second control magnetic valve
In the case of 20 are powered, the oil inlet 18P of the second mechanical slide valve 18 and oil-out 18B can be caused to communicate, so as to which fluid is from oil inlet
18P reaches oil-out 18B, subsequently into second clutch 14, so as to promote second clutch 14 to realize engagement.
The left end control terminal 12A1 (the second control terminal) of second secure mechanical guiding valve 12 is connected to the second mechanical slide valve 18
Oil-out 18B, the right-hand member control terminal 12A2 (the first control terminal) of the second secure mechanical guiding valve 12 are connected to the first mechanical slide valve 17
Oil-out 17B, the oil-out 12B1 of the second safe guiding valve be connected to the second control terminal of the left end of the second mechanical slide valve 18
18A2, the oil-out 12B2 of the second safe guiding valve are connected to the second control terminal of left end 17A2 of 1 first mechanical slide valve 17.
The oil-out of oil-out, the first control magnetic valve 19 in security solenoid valve 11, second control going out for magnetic valve 20
Hydraulic fluid port is respectively provided with accumulator 21 between the control terminal of next valve, can further reduce the fluctuation of control pressure,
Guarantee is precisely controlled to clutch.
Using the scheme of the embodiment of the present invention, the first control magnetic valve 19 or the second control magnetic valve 20 can be caused in event
Under the pattern of barrier, gearbox remains able to work (first clutch 13 still realizes the function of engagement with second clutch 14).
For example, during first clutch 13 works, the first control magnetic valve 19 breaks down so that the first control magnetic valve
19 oil inlet 19P and oil-out 19B cut-out, at this moment can cause, the oil inlet 17P and oil-out 17B of the first mechanical slide valve 17
Cut-out, so as to cause the power cut of first clutch 13.In the technical scheme, there is provided the safe machine of security solenoid valve 11 and first
The secure mechanical guiding valve 12 of tool guiding valve 10 and second, constitutes the standby controlling brancher of clutch, the first mechanical slide valve 17 it is fuel-displaced
The first control terminal connection of the right-hand member of mouth 17B and the second secure mechanical guiding valve 12, pass through the original of storage in the first mechanical slide valve 17
There is pressure to cause fluid to reach the first control terminal of the right-hand member of the second secure mechanical guiding valve 12, so that the second secure mechanical is slided
The the first oil inlet 12P2 and the first oil-out 12B2 of valve 12 are realized and connected, when the first control magnetic valve 19 breaks down, peace
Full magnetic valve 11 works, and can still provide left end the second control terminal 17A2 that pressure oil liquid reaches the first mechanical slide valve 17, so as to
So that the first mechanical slide valve 17 oil inlet 17P and oil-out 17B realize turn on again so that pressure oil liquid arrive again
