Fig. 2 is the another kind of structural representation of guiding valve described in above-mentioned dual-clutch transmission cooling and lubricating system.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present invention dual-clutch transmission cooling and lubricating system is described in detail.
As it is shown in figure 1, the present invention provides a kind of dual-clutch transmission cooling and lubricating system, including:
First clutch lubrication channel and second clutch lubrication channel, the arrival end of these two passages is all connected with lubricant source, the port of export is connected to first clutch and second clutch, and is provided with guiding valve in these two passages；
When described first clutch and second clutch sliding wear, described first clutch lubrication channel and second clutch lubrication channel are connected to the conduction terminal of described guiding valve；After clutch is fully engaged or is kept completely separate, in described first clutch lubrication channel and second clutch lubrication channel be connected to described guiding valve conduction terminal, another be connected to the cut-off end of described guiding valve.
The dual-clutch transmission cooling and lubricating system that embodiments of the invention provide, it is provided with two clutch lubrication passages, realize clutch sliding wear state and the lubrication respectively being fully engaged or being kept completely separate state by controlling the on or off of two clutch lubrication passages, on-demand for amount, thus being effectively saved lubrication flow, save energy consumption, improve cooling effectiveness.
Further, as a kind of improvement to above-described embodiment, described dual-clutch transmission cooling and lubricating system also includes:
Odd number shelves gear lubrication passage 13, its arrival end connects lubricant source, the port of export connects odd number shelves gear, and is provided with the first lubrication reversal valve in described odd number shelves gear lubrication passage 13；
Even gear gear lubrication passage 15, its arrival end connects lubricant source, the port of export connects even gear gear, and is provided with the second lubrication reversal valve in described even gear gear lubrication passage 15；
When odd number shelves working gear, described odd number shelves gear lubrication passage 13 is connected to the conduction terminal of described first lubrication reversal valve, and described even gear gear lubrication passage 15 is connected to the cut-off end of described second lubrication reversal valve；When even gear working gear, described even gear gear lubrication passage 15 is connected to the conduction terminal of described second lubrication reversal valve, and described odd number shelves gear lubrication passage 13 is connected to described lubrication first and lubricates the cut-off end of reversal valve.
It is provided with odd number shelves gear lubrication passage 13 and even gear gear lubrication passage 15, and in respective passage, it is provided with reversal valve, when odd number shelves working gear, described odd number shelves gear lubrication passage 13 turns on, described even gear gear lubrication passage 15 ends, when even gear working gear, even gear gear lubrication passage 15 turns on, odd number shelves gear lubrication passage 13 ends, so, only in running order gear is lubricated, thus being effectively saved lubrication flow, save energy consumption, improve cooling effectiveness.
Yet further, as a kind of improvement to above-described embodiment, described dual-clutch transmission cooling and lubricating system also includes:
First pressure ports 14, its arrival end connects lubricant source, the port of export connects odd number shelves clutch, and is provided with the first pressure regulation reversal valve in described first pressure ports 14；

Odd number shelves, even gear clutch are the mode of alternation, and both can only have one in running order simultaneously.And when there being external force to be applied to clutch, clutch can engage, when being applied to clutch without external force, clutch can be automatically separated.When odd number shelves clutch works, the first pressure ports 14 turns on, and lubricant flows, and now hydraulic system produces power, and this powered odd number shelves clutch engages, and enters duty.Now the second pressure ports 16 ends, and is pushed to even gear clutch without hydraulic power, therefore even gear clutch separation, state of deactivating.Situation contrast when even gear clutch works.Thus can realize the adjustment engaging or separating to clutch.
Specifically, the lubricant towards described odd number shelves, even gear gear lubrication passage 13,15 is through being flowed directly into by lubrication channel 8 and 11 after pressure regulation.Described first, second pressure ports 14,16 is that direct descendant is in working connection 7.Lubricant enters lubrication channel 8 after main pressure regulator valve 1 pressure regulation, lubrication channel 8 branches into first clutch lubrication channel 9, second clutch lubrication channel 10 and lubrication channel 11, and lubrication channel 11 branches into odd number shelves gear lubrication passage 13 and even gear gear lubrication passage 15 again.Here main pressure regulator valve 1 is controlled by electromagnetic valve 3.First pressure ports 14 and the second pressure ports 16 are for be flowed directly into by working connection 7.
Preferably, described first lubrication reversal valve is same valve with described first pressure regulation reversal valve, is the valve 5 shown in Fig. 1, and this valve is two eight logical valves；Described second lubrication reversal valve is same valve with described second pressure regulation reversal valve, is the valve 6 shown in Fig. 1, and this valve is two eight logical valves.So can reduce the quantity of valve, be conducive to the simplification of structure, it is simple to manufacture and later maintenance.
Specifically, described guiding valve 2 is two-position four-way valve (as shown in Figure 1), and after clutch is fully engaged or is kept completely separate, be connected to described guiding valve 2 conduction terminal clutch lubrication passage in be provided with restriction 23.Guiding valve 2 can control its action by electromagnetic valve 4, and electromagnetic valve 4 is connected with working connection 7 by passage 12.So-called two, namely guiding valve 2 has two gears.Such as, in the condition shown in figure 1, when guiding valve 2 is in right side gear, two-way clutch lubrication passage is both turned on, and when guiding valve 2 is in left side gear, two-way clutch lubrication passage Zhong mono-tunnel turns on, another road is ended, and the road turned on is the road being provided with restriction 23, restriction 23 can ensure that clutch can keep suitable lubrication flow when after a clutch is fully engaged and another clutch is kept completely separate.
Under another kind of concrete condition, described guiding valve 2 is three six-way valves (as shown in Figure 2), and after clutch is fully engaged or is kept completely separate, be connected to described guiding valve 2 conduction terminal clutch lubrication passage in be provided with restriction 23 or be connected to described guiding valve 2 cut-off end clutch lubrication passage in be provided with restriction 23.So-called three, namely guiding valve 2 has three gears.Such as, under state shown in Fig. 2, when guiding valve 2 is when left position, being provided with the lubrication channel conducting of restriction 23, another lubrication channel ends, and now flow is minimum；When guiding valve 2 is in middle position, being provided with the lubrication channel cut-off of restriction 23, another lubrication channel turns on, and now flow is moderate；When guiding valve 2 is in right position, two-way lubrication channel is both turned on, now maximum flow.So can regulate, for the lubrication flow of clutch, the selection providing how a kind of.
The above; being only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; change can be readily occurred in or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with described scope of the claims.
