Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The present embodiment provides hydraulic control system and corresponding start and stop strategies, and hydraulic control system is by high-pressure oil passage, gear
Switch oil circuit, locking separation oil circuit, lubricant passage way and start and stop oil circuit composition.The major function of the hydraulic system is:
1, pass through 5 hydraulic actuating mechanisms of control (first clutch, second clutch, third brake, the 4th braking
Device, the 5th clutch) switch state, realize the switching of P/R/N/D gear, wherein D gear is divided into D1/D2/D3/D4/D5/D6 six
Gear.
2, switched according to different operating conditions hydraulic torque converter lockouts/unlock two states.It needs to increase in starting/climbing etc.
The operating condition of torsion is in the unlocked state, reaches and guarantees high transmission efficiency in lockup state after certain speed.
3, cooling/lubrication flow is controlled, realizes the heat exchange of each friction secondary lubrication and transmission assembly.
4, the steady combination of gearbox is realized when needing using start and stop function by energy storage chamber solenoid valve.
To realize start and stop function, the stationarity for keeping start and stop to combine, hydraulic control system has carried out start and stop oil circuit hydraulic
Design, concrete composition such as Fig. 1, the band hydraulic system schematic of start and stop function.In figure, 1, accumulator switch valve；2, accumulator；3, it stores
It can spring；4, accumulator piston；5, accumulator check valve；6, accumulator throttle valve；7 main oil pressure solenoid valves；8, system pressure tune
Save valve；9, filter screen；10, fuel tank；11, oil pump.
The realization of hydraulic control system start and stop function provided in this embodiment is divided into 3 stages.
First stage is the accumulator oil-filled stage, as shown in Fig. 2 energy storage chamber Oil feeding process state diagram.
The stage carries out in engine work, engine rotation, and the present embodiment oil pump 11 is driven to work normally, and produces
Raw pressure oil enters at A, B mouth at 8 place of system pressure regulating valve, and main oil pressure solenoid valve 7 works normally at this time, passes through electric current tune
Section exports controllable control oil pressure, maintains main oil pressure in ideal range of pressure values, if the pressure that oil pump 11 goes out at this time is big
When B, C connect, partial pressure oil lets out oil-feed tank 10, and pressure reduction makes A mouthful pressure be lower, then B, C disconnection, realize main pressure with this
The adjusting of power, in this process, principal pressure oil enter in 2 oil pocket of accumulator through accumulator throttle valve 6, accumulator piston 4
And energy-storaging spring 2 is moved to the left, because of the effect of accumulator throttle valve 6, the process of accumulation of energy is slowly carried out, will not make be
System pressure reduction, after a certain period of time, when accumulator piston 4 is reached when diagram is full of at piston position, piston can be by mechanical structure
It is locked, hydraulic energy is converted to the elastic potential energy of energy-storaging spring 2 at this time, the accumulation of energy process of accumulator 2 terminates.
Second stage is engine off condition, and hydraulic system maintains state diagram when such as Fig. 3 to stall.
When engine is shut down, 11 fuel feeding of oil pump stops, and the pressure oil drops of executing agency are insufficient to allow clutch knot
It closes.For gearbox still in D grades, accumulator has stored full oil liquid in the first stage at this time.Accumulator piston 4 reaches designated position, quilt
Machinery is locked, and accumulator switch valve 1 is closed.
3rd stage was engine restarting stage, hydraulic system working condition schematic diagram when such as Fig. 4 engine restarting.
When engine restarting, engine speed, which reaches idling, regular hour, in this process, system pressure
It establishes slowly, oil pocket inner fluid volume is insufficient.Open mechanical locking mechanism by opening accumulator switch valve 1 at this time, accumulation of energy
Device 2 under the action of energy-storaging spring 3, by the oil liquid in accumulator piston 4 and accumulator oil pocket be packed into rapidly executing agency and
It is insufficient in the oil liquid of starting moment to make up oil pump 11 in the enclosure space that working connection is formed, keep executing agency quick
In conjunction with, while impact when combination is effectively reduced, when engine speed reaches idling or more, system pressure reaches stable
Value, accumulator 2 reenter the first stage.
Accumulator also has pressure stabilization function to system pressure.When the pressure oil fluctuation that oil pump generates, because of energy-storaging spring 2
Presence can effectively sponge the fluctuation of pressure, so that system pressure is tended towards stability.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within；The technology that the present invention is not directed to can be realized by the prior art.
