Description
Technical field
The utility model relates to dual-clutch transmission field, particularly a kind of cooling oil path for dual-clutch transmission.
Background technique
In today that automobile is day by day popular, automotive engineering development, the requirement of client to automobile is more and more stricter.Double-clutch automatic gearbox is accepted by market and client gradually through development for many years.But problem is, often there is following problem in the cooling oil path of prior art: 1, cooler and filter Chang Yinwei blocking decrease the flow of lubricating oil path; 2, solenoid valve (as proportional electromagnetic valve) is only adopted to control clutch lubrication oil circuit, require higher to solenoid valve first, the solenoid valve that volume is larger need be adopted, second once solenoid valve lost efficacy, just to supply clutch peak rate of flow cold oil cannot be ensured, clutch overheat is easily caused to burn the situation causing potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is: the layout providing a kind of cooling oil path is more reasonable, cooling oil path is more unimpeded, low temperature time can protect cooler, prevent from transshipping, the safe and reliable cooling oil path for dual-clutch transmission.
The technical scheme in the invention for solving the above technical problem is: a kind of cooling oil path for dual-clutch transmission, comprise cooler, working connection pressure regulator valve and cooler and be arranged in parallel cooler bypass valve between working connection and lubricating oil path and lubricating oil path modulating valve, the filler opening of described cooler is connected with described working connection pressure regulator valve, and the filler opening of described cooler bypass valve is also connected with described working connection pressure regulator valve; And first of cooler oil outlet the lubrication branch road is connected with gear, bearing lubricating oil circuit, second lubrication branch road of cooler oil outlet is connected with clutch lubrication oil circuit by lubricating oil path modulating valve, and described lubricating oil path modulating valve is also connected with the pressure ratio control valve often opened.
Compared with prior art, the utility model has the advantage of: this cooler being used for the cooling oil path of dual-clutch transmission is configured in the upstream of cooling oil path by bypass valve, working connection pressure regulator valve for regulating working connection pressure, distribute lubrication oil road flow.The cooler bypass valve be arranged in parallel with cooler then can prevent cooler because block the flow decreasing lubricating oil path, ensures the unimpeded of cooling oil path.First branch road of cooler oil outlet and gear, bearing lubricating oil circuit is connected, second branch road of cooler oil outlet is connected with clutch lubrication oil circuit by lubricating oil path modulating valve, lubricating oil path modulating valve is then for regulating the assignment of traffic of clutch lubrication oil circuit, and lubricating oil path modulating valve is controlled by the pressure proportioning valve often opened, not only can effectively reduce the volume of solenoid valve, and the potential safety hazard that prior art was brought when solenoid valve lost efficacy can be avoided, can ensure that clutch obtains peak rate of flow cold oil, the security risk preventing from clutch overheat from burning causing.Should be more reasonable in the layout of the cooling oil path of double-clutch speed changer, cooling oil path is more unimpeded, safe and reliable, controllable adjustment lubrication flow size, pulls moment of torsion, raise the efficiency when reducing clutch low temperature.
As preferably, it also comprises cooler pressure-limit valve, the entrance of described cooler pressure-limit valve directly with the outlet of described cooler be connected, the outlet of described cooler pressure-limit valve is connected with fuel tank.Like this, pressure-limit valve protects cooler and line connection thereof when low temperature, avoids pressure overload.
As preferably, it also includes one-way valve and filter, and the oil outlet of described cooler is communicated with the import of filter and the import of one-way valve.Filter can ensure the turbidity test requirement of gear box oil, reduces the rate of fault of solenoid valve or guiding valve.Filter is furnished with bypass one-way valve, and protection filter is kept away blocking and reduces the flow of lubricating oil path.
As preferably, described cooler and filter and one-way valve integral type integrated.Like this, space arrangement convenience.
As preferably, the 3rd lubrication branch road of described cooler oil outlet is connected with mixed power lubricating oil path.
Accompanying drawing explanation
Fig. 1 is the cooling oil circuit structure schematic diagram of the utility model for dual-clutch transmission.
In Fig. 1: 1 cooler, 2 bypass valve, 3 working connection pressure regulator valves, 4 cooler pressure-limit valves, 5 lubricating oil path modulating valve, 6 pressure ratio control valves, 7 gears, bearing lubricating oil circuit, 8 mixed power lubricating oil paties, 9 clutch lubrication oil circuits, 10 one-way valves, 11 filters.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figure 1, a kind of cooling oil path for dual-clutch transmission, comprise cooler 1, working connection pressure regulator valve 3 and cooler 1 and be arranged in parallel cooler bypass valve 2 between working connection and lubricating oil path and lubricating oil path modulating valve 5, the filler opening of described cooler 1 is connected with described working connection pressure regulator valve 3, and the filler opening of described cooler bypass valve 2 is also connected with described working connection pressure regulator valve 3; And first of cooler 1 oil outlet the lubrication branch road is connected with gear, bearing lubricating oil circuit 7, second lubrication branch road of cooler 1 oil outlet is connected with clutch lubrication oil circuit 9 by lubricating oil path modulating valve 5, and described lubricating oil path modulating valve 5 is also connected with the pressure ratio control valve 6 often opened.
It also comprises cooler pressure-limit valve 4, the entrance of described cooler pressure-limit valve 4 directly with the outlet of described cooler 1 be connected, the outlet of described cooler pressure-limit valve 4 is connected with fuel tank.
It also includes one-way valve 10 and filter 11, and the oil outlet of described cooler 1 is communicated with the import of filter 11 and the import of one-way valve 10.
Described cooler 1 and filter 11 and one-way valve 10 integral type integrated.
3rd lubrication branch road of described cooler 1 oil outlet is connected with mixed power lubricating oil path 8.
During low temperature, due to clutch lubrication oil circuit 9, bearing lubricating oil circuit 7, or the pipeline oil duct resistance of mixed power lubricating oil path 8 increases, and cooler 1 (comprising filter 11) and model calling place pressure may exceed safety range.Pressure-limit valve 4 can limit the pressure of cooler 1 oil outlet place oil circuit to reach the object of protection pipeline.Simultaneously; because cooler 1 and filter 11 oil duct resistance increase, when cooler 1 filler opening place pressure ratio pressure-limit valve 4 setting pressure is higher than certain value, cooler bypass valve 2 is opened; be communicated with cooler 1 filler opening and filter 11 oil outlet, to reach the object of protection cooler 1 filler opening place pipeline.
Below only just most preferred embodiment of the present utility model is described, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in the utility model protection domain.
