Principle of work of the present utility model is described below, and its different operating state according to separation, combination and combination fast illustrates.
The principle of work separating is as follows:
When control unit 42 receives after electronics clutch pedal signal, control unit 42 makes respectively large flow electromagnetic valve module 8 exhaust coil electricities according to programming control strategy by large flow solenoid valve plug 9 and wire harness, this plug and wire harness are three holes and three heart yearns, wherein intake and exhaust coil connects each one, this wire energising and power-off are all controlled controlled unit 42, an other wire is coil common ground negative pole, when the moving iron core 10 of large flow electromagnetic valve exhaust after exhaust coil electricity down moves and opens admission port under coil magnetic action, and close lower end exhausr port, pressure gas enters large flow diaphragm stop valve intake and exhaust channel 13, under pressure gas effect, large flow diaphragm stop valve exhaust diaphragm 14 is closed, after closing the time delay of large flow diaphragm stop valve exhaust diaphragm, large flow electromagnetic valve module 8 air inlet coils are switched on again, the moving iron core 11 of large flow solenoid valve air inlet up moves and closes air inlet source under air inlet coil magnetic action, pressure gas is discharged from large flow electromagnetic valve outlet 12 through large flow diaphragm stop valve intake and exhaust channel 6, now large flow diaphragm stop valve air inlet diaphragm 5 is opened, source of the gas enters power-assisted epitrochoidal chamber 31 from gas servo cylinder intake and exhaust channel 1, now gas boosting piston 30 and push rod 26 displacement to the right under pressure gas effect, promoting change speed gear box platen separation rocking arm 24 rotates, clutch driving disc is separated, the straight gear pull bar 35 being now connected on gas boosting piston 30 moves together with straight gear 2, and drive sector rotating shaft 36 to rotate, the magnet steel 38 being meanwhile connected on magnet steel shaft seat 40 also rotates together, there is pole change with Hall chip 39 in magnet steel 38, through sensor internal processing of circuit, convert analog signal output to and send control unit 48 to, after control unit 42 receives these two kinds of signals, according to the proportionate relationship of these two kinds of signals, adjust different corresponding positions, when angle signal, to change when fast pushrod movement fast, when angle signal, to change when slow pushrod movement slow, remain that relation is between the two synchronous.Refer to Fig. 3.
When the signal of electronics clutch pedal assembly 45 approaches disengaged position expected value soon, large flow electromagnetic valve module 8 power-off, coil magnetic force disappears, the moving iron core 11 of large flow solenoid valve air inlet down moves and opens air inlet source under the effect of pull back spring, large flow diaphragm stop valve air inlet diaphragm 5 is opened, pressure gas enters through large flow diaphragm stop valve intake and exhaust channel 6, under pressure gas effect, closes diaphragm, and power-assisted epitrochoidal chamber 31 pressure can not keeping not arrange.Because release travel does not also reach expected value, now low-flow electromagnetic valve module 18 air inlet coil electricities.Low-flow electromagnetic valve plug 17 and wire harness are three hole three core conductor compositions, intake and exhaust coil is each connects one, control unit 48 is controlled energising and the power-off of intake and exhaust coil, an other wire is common ground negative pole, when the moving iron core 19 of low-flow electromagnetic valve air inlet after air inlet coil electricity moves downward, pressure gas enters through intake and exhaust channel 20 and cylinder power-assisted intake and exhaust channel 1, make power-assisted epitrochoidal chamber 31 pressure risings, gas boosting piston 30 and push rod 26 continue to move right under pressure gas effect, now ECU can switch on and power-off control to low-flow electromagnetic valve module 18 according to the signal intensity of stroke sensor assembly 37, realize the accuracy of push rod release travel, the variation of push rod stroke is directly fed back in the signal of stroke sensor, when push rod release travel arrives expected value, low-flow electromagnetic valve module 18 air inlet coil blackout magnetic force disappear, moving iron core 19 upward movements of low-flow electromagnetic valve air inlet are closed admission port, change speed gear box platen separates rocking arm 24 and loads in situation about equating with push rod 26 loads, release travel keeps current location constant, if when push rod release travel has exceeded the expected value of regulation, low-flow electromagnetic valve module 18 exhaust coil electricities, the moving iron core 21 of low-flow electromagnetic valve exhaust is worked and moves downward, now power-assisted epitrochoidal chamber 31 pressure gass are through cylinder power-assisted intake and exhaust channel 1, intake and exhaust channel 20 and low-flow electromagnetic valve outlet are discharged, gas boosting piston 30 is moved to the left under the effect of Fen Li rocking arm 24 loads of change speed gear box platen with push rod 26, in exhaust process, also can to the intake and exhaust coil of low-flow electromagnetic valve module 18, control to reach exact location as required, complete after expected value control, low-flow electromagnetic valve module 18 air inlet coil blackouts, moving iron core 21 upward movements of low-flow electromagnetic valve air inlet are closed exhausr port 22, guarantee the regulation requirement of push rod release travel expected value, above-mentioned, step in the whole process of clutch pedal 42, if being parked in optional position push rod 26, clutch pedal 42 also can stop at corresponding position, thereby servo-actuated property and the synchronism of clutch pedal 42 and push rod 26 have been guaranteed.
Vehicle start in conjunction with time principle of work as follows:
After completing separate targets value, when electronic control unit 42 receives after exhaust signal, the exhaust coil blackout of large flow electromagnetic valve module 8 disappears magnetic force, the moving iron core 10 of large flow electromagnetic valve exhaust up moves and closes air inlet source under the effect of pull back spring, large flow diaphragm stop valve exhaust diaphragm 14 is opened under pressure gas counteraction, now the gas of power-assisted epitrochoidal chamber 31 is crossed gas servo cylinder intake and exhaust channel 1 and large flow electromagnetic valve outlet 12 is discharged, if electronics clutch pedal signal is when vehicle start calmodulin binding domain CaM scope, now the exhaust coil of large flow electromagnetic valve module 8 is switched on again, the moving iron core 10 of large flow electromagnetic valve exhaust down moves and closes exhaust, pressure gas is through large flow diaphragm stop valve intake and exhaust channel 13 and close large flow diaphragm stop valve exhaust diaphragm 14, no longer increase the pressure gas that enters gas servo cylinder intake and exhaust channel 1, the position of realizing push rod 26 stops, if now electronics clutch pedal assembly 45 signal intensities are very slow, low-flow electromagnetic valve module 18 is switched on, the moving iron core 21 of low-flow electromagnetic valve exhaust is worked and moves downward, now the gas of power-assisted epitrochoidal chamber 31 is through cylinder power-assisted intake and exhaust channel 1, intake and exhaust channel 20 and low-flow electromagnetic valve outlet 22 are discharged, ECU can complete a series of action according to the variation of pedal angle signal, until steadily complete efficiently vehicle start.
When vehicle fast in conjunction with time principle of work as follows:
After completing separate targets value, when electronics clutch pedal signal intensity is very fast, the exhaust coil blackout of large flow electromagnetic valve module 8 disappears magnetic force, the moving iron core 10 of large flow electromagnetic valve exhaust up moves and closes air inlet source under the effect of pull back spring, large flow diaphragm stop valve exhaust diaphragm 14 is opened under pressure gas counteraction, now the gas of power-assisted epitrochoidal chamber 31 is discharged through cylinder power-assisted intake and exhaust channel 1 and large flow electromagnetic valve outlet 12, during this action, generally do not control the position of push rod 26, make push rod 26 to get back to initial condition by fast speed, thereby realize the quick combination of power-transfer clutch
