Exempt to influence control accuracy, after air discharge, breather plug 34 is shut and disconnects the power supply of motor 13.
After the completion of preparation stage, by the access vehicle-mounted control such as reversal valve 25, pressure sensor 26, angular displacement sensor 38 system
System, the data that vehicle control syetem can gather pressure sensor 26, angular displacement sensor 38 measures, and control in reversal valve 25
Each passage on and off, realize the control to oil circuit.
Being filled afterwards for accumulator 21 can, it is necessary first to which the clutch parameter of control required for understanding, calculates the control
The required minimum operating pressures that of mechanism and maximum working pressure (MWP), need to be to ensure the stabilization and reliability of the control mechanism
Required minimum operating pressures that suitably adds a part of pressure, suitably reduces a part of pressure on specified maximum working pressure (MWP).It is false
If selected minimum operating pressures that is X MPa, maximum working pressure (MWP) is Y MPa, first controls reversal valve 25, closes input hole 223,
Accumulator 21 is connected with oil pumping system 1 at this time, is powered to motor 13, while monitors 26 data of pressure sensor, treats that pressure passes
When 26 data of sensor reach Y MPA, motor 13 is powered off, since check valve 24 acts on so that at this stage in state accumulator 21
For required high pressure oil.
Below with three kinds of states of clutch：Three kinds of separation, combination, pressurize states illustrate embodiments thereof respectively：
1st, discrete state：When want to allow clutch separation when, control the sliding block in reversal valve 25 to reach oil return hole 225 position,
Oil return hole 225 closes at this time, and accumulator 21 is connected with working cylinder system 3, and the high pressure oil in accumulator 21 is passed through working cylinder at this time
In system 3 so that the piston 31 in working cylinder system 3 moves backward, while piston 31 drives drag-line 33 to move backward, supervises at the same time
38 data of angle measurement displacement sensor, when piston 31 is moved to so that during clutch separation, this process is completed.
2nd, engagement state：When needing to allow clutch to engage, sliding block in reversal valve 25 is controlled to reach 223 position of input hole,
Input hole 223 closes at this time, and working cylinder system 3 connects the oil storage box 12 in oil pumping system 1 by low-pressure oil return pipe 6, makes work
3 release of cylinder system, the active force of spring is ground by clutch, and clutch automatically returns to closure state, and piston 31 returns at this time
Initial position, this process are completed.
3rd, packing state:This state is similar with above-mentioned discrete state, i.e. long-time discrete state, at this time only need to be according to separation
The working forms of state, keep electromagnetic type reversal valve 25 to be powered for a long time, keep the sliding block in reversal valve 25 to be maintained at for a long time
225 position of oil return hole.
After the repeatedly circulation above process, the oil pressure in accumulator 21 can be reduced gradually, when pressure sensor 26 measures oil
When pressure is less than X MPa, repetition is above-mentioned to fill energy state to accumulator 21, is powered to the motor 13 in oil pumping system 1, is accumulator 21
Energy is filled, is powered off when pressure sensor 26 is measured when pressure is more than Y MPa, the circulating repetition above process.
Above-described embodiment, the purpose of this utility model, technical solution and beneficial effect have been carried out into
One step describes in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
