Description
Technical field
The present invention relates to the hydraulic control system of automotive transmission, particularly the hydraulic control system of automobile double clutch automatic gearbox.
Background technique
Double-clutch automatic gearbox has two clutches, the mode that adopts pre-engage a gear and two engaging power to switch, reduced the time of gear shift power interruption, improved the power character of system, simultaneously the double clutch automatic speed changing system has adopted the drive mechanism of traditional fixed axis gear-synchronizer, and transmission efficiency height, fuel economy are good.
The parts that electrohydraulic control system is most critical in the double-clutch automatic gearbox, complex structure, cost is high guaranteeing under the prerequisite of performance hydraulic system to be done suitable simplification, help reducing the manufacture cost and the manufacture difficulty of double clutch automatic speed changing system.The research and development of U.S. BorgWarner Inc have also been produced the DQ250 automatic transmission in batches, and granted U.S. Pat 2006/0005647A1, in this hydraulic system only the gear shift of six-speed gearbox part just adopted seven solenoid valves, corresponding TCU controller has seven tunnel power drive output channels, the gear shift selector valve has adopted two 17 logical selector valves, system is very complicated, involves great expense.Qingshan Ind Co Ltd, Chongqing has proposed to adopt the scheme of two nine logical selector valves and two solenoid valves (to see " double-clutch speed changer integrated control module " at the five speed transmission system, number of patent application 200910260308.9), simplified system significantly, reduced cost, in this system, reverse gear R has adopted hand-operated direction valve directly to control the scheme of R gear shift hydraulic oil cylinder driving shift fork gear shift, the return of reverse gear R adopts return spring to realize, when hand-operated direction valve withdraws from the R shelves, the off-load of R gear shift oil cylinder oil pressure, the R shelves make the return trip empty under the effect of return spring.
Find that in actual applications adopt the mode of R shelves spring return to have following shortcoming: when spring rate was big, correspondence had improved the oil pressure of R gear shift oil cylinder, had reduced the efficient of system, and spring assembling simultaneously is difficulty also; When spring rate hour, can not guarantee R shelves return reliably again, therefore the poor reliability of system is necessary the reverse gear control mode of making the return trip empty is improved.
Summary of the invention
The purpose of this invention is to provide a kind of double-clutch automatic gearbox hydraulic control system, to realize the reliable return of double clutch R shelves.
Double-clutch automatic gearbox hydraulic control system of the present invention, comprise the Clutch Control module that is used for selectivity and switches each clutch independently, the gear shift control module that is used for the synchronizer shift of drive speed transmission, the clutch refrigerating module that is used for the solenoidoperated cluthes cooling liquid, the axle that is used to control the speed changer inner shaft and is cooling liquid is refrigerating module and the main pressure regulator module that is used to regulate whole hydraulic system pressure, in the gear shift control module, have two gear shift solenoid valves and a R gear shift oil cylinder, in the Clutch Control module, has shift valve, R gear shift oil cylinder is communicated with shift valve by R gear shift oil circuit, in the output circuit in two gear shift solenoid valves separately parallel connection draw the R shelves oil circuit that makes the return trip empty, and these two R shelves oil circuit that makes the return trip empty is connected with two input ends of shuttle valve respectively, the output terminal of shuttle valve is communicated with the spring chamber of R gear shift oil cylinder by the output circuit that makes the return trip empty.
Be connected with selector valve in the output circuit that makes the return trip empty, the selector valve right-hand member is communicated with R gear shift oil circuit.
Be in series with the one-way throttle valve assembly in the output circuit that makes the return trip empty, it is between shuttle valve and selector valve.
Adopt technical solution of the present invention can remove the in-oil cylinder return spring of R gear shift, or significantly reduce the rigidity of return spring.The output circuit of two gear shift solenoid valves is communicated with the spring chamber of R gear shift oil cylinder by make the return trip empty oil circuit, shuttle valve and the output circuit that makes the return trip empty of R shelves, utilize shuttle valve or function, can controlled realization R shelves make the return trip empty gear shift that also can controlled realization R shelves.
The selector valve that connects in the output circuit that makes the return trip empty, when can be implemented in the R shelves, R gear shift oil cylinder spring chamber is by this selector valve emptying.
The one-way throttle valve assembly of connecting in the output circuit that makes the return trip empty can improve the quality of making the return trip empty of R shelves.
Double-clutch automatic gearbox hydraulic control system of the present invention is increasing limited structure and cost, do not increase on the basis of solenoid valve and TCU controller output channel, efficiently solve the technical problem of the reliable return of double clutch R shelves, make the return of double clutch R shelves more reliable, improved the reliability of double-clutch automatic gearbox hydraulic control system work.
