In the time that car load normally moves, be filled with respectively the gas of certain pressure by the import of power-assisted air pressure and the import of control air pressure, now be positioned at the groove of piston rod 2 outer peripheral faces due to the spool of control valve 5, therefore power-assisted air pressure air inlet 3 disconnects with the import of power-assisted air flue, the gas being filled with in power-assisted air pressure air inlet 3 cannot enter in the rear chamber 13 of power-assisted cylinder body 17 by power-assisted air flue 6, thereby all concentrates on power-assisted air pressure air inlet 3 places, steel ball 8 in reversal valve 7 valve roads is positioned at reversal valve 7 bottoms, valve road under self gravitation, the gas of controlling air pressure air inlet 4 places enters reversal valve 7 valve roads, steel ball 8 moves upward to reversal valve 7 tops, valve road in gas pressure Xia Yanfa road, now power-assisted air flue import and power-assisted air flue outlet 11 are disconnected, control air pressure air inlet 4 and control air flue import conducting, gas enters the rear chamber 13 of power-assisted cylinder body 17 by controlling air flue 10, servo-cylinder piston 19 drives piston rod 2 to move forward under gas pressure effect, thereby make the control spool of the control valve 5 that is positioned at piston rod 2 side face grooves deviate from gradually groove, piston rod 2 side faces of groove outside move down by pressure control valve core, thereby make the import conducting of power-assisted air pressure air inlet 3 and power-assisted air flue, the gas at power-assisted air pressure air inlet 3 places enters in power-assisted air flue 6, the steel ball 8 that gas push is positioned at reversal valve 7 tops moves down, thereby steel ball 8 is positioned in the middle of reversal valve 7 valve roads, now power-assisted air flue import and power-assisted air flue export 11 conductings, control air pressure air inlet 4 and control air flue import conducting, the gas at power-assisted air pressure air inlet 3 places enters the rear chamber 13 of power-assisted cylinder body 17 by power-assisted air flue 6, two bursts of gas actings in conjunction controlling in air flue 10 and power-assisted air flue overcome piston spring 18 pulling force on piston rod 2, promoting servo-cylinder piston 19 moves forward, thereby the clutch push rod 12 connecting on servo-cylinder piston 19 is moved forward, clutch separation, gas in power-assisted cylinder body 17 is discharged from controlling air pressure air inlet 4 by controlling air flue 10, along with the continuous discharge of gas, air pressure in the rear chamber 13 of power-assisted cylinder body 17 constantly reduces, in the time that this air pressure is less than the pulling force of piston spring 18 to the thrust of servo-cylinder piston 19, servo-cylinder piston 19 moves rapidly backward, gas in the rear chamber 13 of power-assisted cylinder body 17 is discharged by control valve 5 from power-assisted air flue 6 simultaneously, clutch push rod 12 is mobile withdrawal backward, again enter in the groove of piston rod 2 and power-assisted air pressure air inlet 3 and power-assisted air flue 6 are disconnected until control spool, air pressure in reversal valve 7 valve roads disappears, steel ball 8 again falls back to reversal valve 7 bottoms, valve road under self gravitation effect.
When hybrid power part breaks down, when vehicle cannot normally travel, enter Electromagnetic Drive pattern, now car load air pressure enters from power-assisted air pressure air inlet 3, but because the spool of control valve 5 is positioned at the groove of piston rod 2 outer peripheral faces, therefore power-assisted air pressure air inlet 3 disconnects with the import of power-assisted air flue, and the gas being filled with in power-assisted air pressure air inlet 3 cannot enter in the rear chamber 13 of power-assisted cylinder body 17 by power-assisted air flue 6, thereby all concentrates on power-assisted air pressure air inlet 3 places, now control air pressure air inlet 4 places and there is no air pressure, steel ball 8 in reversal valve 7 valve roads in valve road bottom, is therefore controlled air pressure air inlet 4 and controls that air flue 10 disconnects, the import of power-assisted air flue is with power-assisted air flue outlet 11 and control air flue import while conducting under self gravitation effect, switch on power, external power source is switched on to solenoid 1 by wire harness 15, solenoid 1 produces magnetic field thrust, piston rod is magnetic strip piston rod, therefore piston rod 2 travels forward under the thrust of magnetic field, servo-cylinder piston 19 moves to front chamber 14 under the thrust of piston rod 2, along with the movement of piston rod 2, the control spool that is positioned at piston rod 2 grooves is deviate from groove gradually, and make power-assisted air pressure air inlet 3 and power-assisted air flue import conducting at piston rod 2 outer peripheral faces by depressing to move down, the gas at power-assisted air pressure air inlet 3 places enters by control valve 5 in the power-assisted air flue 6 of " Z " font, due to now power-assisted air flue import and power-assisted air flue outlet 11 and control air flue import conducting simultaneously, therefore gas enters in the rear chamber 13 of power-assisted cylinder body 17 by power-assisted air flue outlet 11 and control air flue 10, in the time that the gas pressure of rear chamber 13 of power-assisted cylinder body 17 and the magnetic field thrust of solenoid 1 are greater than the pulling force of piston spring 18, compressing servo-cylinder piston 19 moves to front chamber 14, promotion clutch push rod 12 moves forward and makes clutch separation, deenergization is the current vanishes on solenoid 1, solenoid 1 disappears to the magnetic field thrust of piston rod 2, the pressure that servo-cylinder piston 19 is subject to is less than the pulling force of piston spring 18, servo-cylinder piston 19 drives piston rod 2 and clutch push rod 12 to move backward rapidly, clutch push rod 12 is regained, gas in the rear chamber 13 of power-assisted cylinder body 17 enters power-assisted air flue 6 from power-assisted air flue outlet 11 and the outlet of control air flue, finally discharge by control valve 5, piston rod 2 resets under piston spring 18 pulling force effects, controlling spool is embedded in the groove of piston rod 2, power-assisted air pressure air inlet 3 disconnects with the import of power-assisted air flue. the external position sensor 9 that is provided with of servo-cylinder, position sensor 9 gathers the concrete movement position of servo-cylinder piston 19, thus separation and the bonding state of the position judgment clutch of the servo-cylinder piston 19 that can collect according to position sensor 9.
The clutch slave cylinder that the present invention proposes adopts magnetic field force and the pure air pressure that solenoid produces to drive two kinds of drive patterns to realize clutch operating, can realize drive pattern exchanges, increase work efficiency, adopt the magnetic field force that electric current produces to replace hydraulic oil, save vehicle operating cost, save energy consumption, reduce and pollute, clean environment firendly.
The present invention adopts the motion of solenoid piston rod and control valve is moved downward, the import conducting of power-assisted air pressure air inlet and power-assisted air flue will be made, owing to there not being hydraulic oil, therefore control valve does not bear the pressure of hydraulic oil, thereby reduce the requirement of sealing, oil resistivity and the resistance to pressure of control valve, reduced cost.
Electromagnet apparatus is the magnetic strip piston rod segment of solenoid and piston rod in the present embodiment, also can directly adopt in other embodiments of the invention electromagnet, all be set to electromagnet by piston rod and solenoid, by changing the ferromagnetic mode of one of them electromagnetism, utilize electromagnet to carry out piston rod motion with the characteristic that magnetic is repelled each other, different Magnetic Phase is inhaled.
On piston rod, be wholely set in the present embodiment magnetic strip piston rod segment, the iron core in electromagnet apparatus and piston rod also can adopt split-type structural in other embodiments of the invention.
The output of electromagnet apparatus is the magnetic strip piston rod segment being wholely set on piston rod in the present embodiment, also can make in other embodiments of the invention the output of electromagnet apparatus and clutch push rod be in transmission connection.
