Fig. 1 is visible, and present invention additionally comprises the second lubrication lubrication damping hole 30 of valve spring 33 and second of valve 12, second for reversal valve；Institute
The second lubrication valve spring 33 is stated installed in the non-controlling end of the second lubrication valve 12；The first lubrication valve 11 is decompression proportioning valve；
The input of the proportion magnetic valve 10 is connected with system pressure oil circuit 20, output end passes through the 3rd oil circuit 24 and the 4th oil respectively
Road 25 is connected with the control end of the first lubrication lubrication valve 12 of valve 11 and second；One end of the oil circuit 23 of first oil circuit 22 and second
It is connected with flow input oil circuit 21, the other end of the first oil circuit 22 is connected with the input of the second lubrication valve 12, the second oil circuit
23 other end is connected with the input of the first lubrication valve 11；One end of 7th oil circuit 28 and the output of the first lubrication valve 11
End is connected, and the other end is connected with one end of the 5th oil circuit 26 and the 8th oil circuit 29, the other end and second of the 5th oil circuit 26
The output end connection of valve 12 is lubricated, the other end of the 8th oil circuit 29 is connected with clutch；First damping hole 31 is set
In the first oil circuit 28, the size in its aperture is adapted with flow oily in the first oil circuit 28；Second damping hole 30 is set
In the 7th oil circuit 22, the size in its aperture is adapted with flow oily in the 7th oil circuit 22.So, the present invention is in vehicle
On upper abrupt slope during continuous driveaway operation, when abrupt slope starting needs to obtain larger lubrication flow particularly on vehicle is continuous,
Can adoption rate magnetic valve 10 control first lubricate valve 11 and second lubrication valve 12 clutch need smaller lubrication flow when,
Only first lubrication valve 11 works, and the first lubrication valve 11 is decompression proportioning valve, and this just can accurately control the 7th oil circuit 28
Pressure and flow, thus can accurately control and to clutch provide compared with small lubrication flow；When clutch needs big lubrication flow
When, the first lubrication lubrication valve 12 of valve 11 and second works simultaneously, and the second lubrication valve 12 is reversal valve, so can be to clutch
Larger lubrication flow is provided.Therefore, it is possible to preferably accurate control lubrication flow, and normally transported on smooth-going road surface in vehicle
Row, clutch do not produce heat not requirement larger lubrication flow when, do not provide larger lubrication flow to clutch and reduce
The dragging energy consumption of clutch, and then make the oil consumption of vehicle smaller, vehicle dynamic economicses are preferable.
The proportion magnetic valve 10 is the vacuum solenoid valve of ratio pressure.Thus, proportion magnetic valve 10 can preferably to
The first lubrication lubrication valve 12 of valve 11 and second provides different output pressures, and preferably control first lubricates the profit of valve 11 and second
The working condition of guiding valve 12.
The first lubrication valve 11 is two four-way mechanical relief valves, and the second lubrication valve 12 is two-bit triplet reversal valve.Cause
And, in this way, it is possible to which preferably when the output pressure of proportion magnetic valve 10 is relatively low, the only first lubrication valve 11 works, by first
Lubricate valve 11 and provide less lubrication flow to clutch, when the output pressure of proportion magnetic valve 10 is higher, the first lubrication valve 11
Worked simultaneously with the second lubrication valve 12, and larger lubrication flow is provided to clutch, preferably lubrication flow is accurately controlled
System.
First lubrication valve spring 32, the second lubrication valve spring 33 is type identical cylindrical helical compression spring,
The pretightning force of the first lubrication valve spring 32 is 5N, and the initial tension of spring of the second lubrication valve spring 33 is 10N.Such one
Come, it becomes possible to preferably relatively low in the output pressure of proportion magnetic valve 10, when being only capable of overcoming the pretightning force of the first lubrication valve spring 32,
First lubrication valve 11 is in operating position, and the second lubrication valve 12 is in the closed position, and less lubrication flow is provided to clutch,
And can preferably the output pressure of proportion magnetic valve 10 it is higher, the pretightning force and second of the first lubrication valve spring 32 can be overcome
When lubricating the pretightning force of valve spring 33, the first lubrication lubrication valve 12 of valve 11 and second is carried all in operating position, and to clutch
For larger lubrication flow, what is preferably accurately controlled is carried out to lubrication flow.
The operation principle of the present invention is as follows：
Referring to Fig. 1, by adjusting the size of the output pressure of proportion magnetic valve 10, control first lubricates valve 11 and second and lubricated
The operating position of valve 12, so as to control different lubrication flows, can carry out more small but excellent true lubrication flow control to clutch
System, can carry out larger lubrication flow to clutch again and control.
More small but excellent true lubrication flow can be carried out to clutch to control.Proportion magnetic valve 10 is adjusted, makes proportion magnetic valve
10 output pressure is relatively low, is only capable of overcoming the pretightning force of the first lubrication valve spring 32, is not enough to overcome the second lubrication valve spring 33
During pretightning force, now the only first lubrication valve 11 is in operating position, and the second lubrication valve 12 is in off-position.Now, the 3rd
The collective effect of cooling oil oil pressure and the first lubrication valve spring 32 determines oily in the 7th oil circuit 28 in oil circuit 24, the 6th oil circuit 27
Size is pressed, so as to adjust from the 7th oil circuit 28 to the cooling oil flow in the 8th oil circuit 29.Now the first oil circuit 22 and the 5th is oily
Road 26 disconnects, and the cooling of clutch and lubricating oil all are from the 7th oil circuit 28.Now the lubricating oil pressure of the 7th oil circuit 28 with
The output pressure of proportion magnetic valve 10 changes and changed, and the second damping hole 31 is present on the 7th oil circuit 28, due to the second damping hole
31 effect, when the 7th oil circuit 28 oils buckling, the flow of lubrication for flowing through the second damping hole 31 changes and become with oil pressure
Change, so as to realize the accurate adjustment that flow is lubricated to clutch.
A kind of dual-clutch transmission lubrication flow adjusting means of the present invention, can also carry out larger lubrication to clutch
Flow is controlled.Proportion magnetic valve 10 is adjusted, makes the output pressure of proportion magnetic valve 10 higher, the first lubrication valve spring can overcome
When 32 pretightning force and the pretightning force of the second lubrication valve spring 33, the first lubrication lubrication valve 12 of valve 11 and second is in working position
Put.Now, the first oil circuit 22 is connected with the 5th oil circuit 26, and the second oil circuit 23 is connected with the 7th oil circuit 28, the cooling of clutch and
Lubricating oil comes from the 5th oil circuit 26 and the 7th oil circuit 28, so as to obtain larger lubrication flow.First damping hole 30 is present in
On one oil circuit 22, its effect is limited flowing to the flow of lubrication in the 5th oil circuit 26 from the first oil circuit 22, identical
Under oil pressure, the aperture of the first damping hole 30 is bigger, and the flow of lubrication flowed to from the first oil circuit 22 in the 5th oil circuit 26 is bigger, specifically
The pore size of first damping hole 30 is determined according to the actual requirements.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, skill of this area ordinary skill technical staff to the present invention
In various modifications and improvement that art scheme is made, the protection domain that claims of the present invention determination all should be fallen into.
