The generic set accepted way of doing sth lightweight ABS electromagnetic valve of the present invention, it adopts a sealing member to realize the sealing of all inlet channels, output channel and exhaust passage, reduces the seal point of product, reduces the chance of failure of product.As shown in Figure 1 and Figure 2, special-shaped seal ring 17 is located between bottom deck assembly 16 and valve body 18, and whole abnormity passage is only with a sealing member, thus substantially reducing the seal point of product, reduces the chance of failure of product.
The generic set accepted way of doing sth lightweight ABS electromagnetic valve of the present invention, its operation principle is as follows:
The generic set accepted way of doing sth lightweight ABS electromagnetic valve of the present invention is as the part of ABS pile-up valve (+two ABS electromagnetic valves of a relay valve), the air-path interface of whole ABS pile-up valve assembly has control mouth, air inlet and delivery outlet, air inlet has air pressure all the time, and the source of the gas of the 7th air inlet 111 shown in Fig. 5 is from the delivery outlet of ABS pile-up valve.
The generic set accepted way of doing sth lightweight ABS electromagnetic valve of the present invention, the operation principle that its conventional brake controls process (pressurization stages) is as follows:
In conventional brake, the first electromagnetic valve controls end 601, public control end 602 and the second electromagnetic valve and controls the equal no power work of end 603, pressurization stages in suitable abs braking system: driver steps on foot brake valves, air pressure promote relay valve control mouth piston upper chamber, piston move downward back down valve make the air pressure of air inlet flow to delivery outlet arrive ABS electromagnetic valve the 7th air inlet 111.
Now the air pressure of the 7th air inlet 111 flows to path and is:
One tunnel is the 7th air inlet 111 the 8th air inlet 112 first air inlet 301 second air inlet 302 the 3rd air inlet 303, and under the effect of the dynamic iron core 6 of air inlet spring 4 and air inlet, air pressure rests on the valve port place of air intake valve 2；
Another road is the air pressure from ABS pile-up valve assembly air inlet, delivery outlet through relay valve portion arrives the 7th air inlet 111 of ABS electromagnetic valve, finally arrive the 6th delivery outlet 221, concrete path is the 7th air inlet 111 the 8th air inlet 112 the 4th air inlet 401 the 5th air inlet 402 the 6th air inlet 403 the 3rd delivery outlet 404 second gas outlet 405 the 4th delivery outlet 406 the 5th delivery outlet 407 the 6th delivery outlet 221, and the air pressure of the 6th delivery outlet 221 withstands the aerofluxus diaphragm of ABS pile-up valve assembly and closes air vent；With time simultaneously, the delivery outlet air pressure through relay valve portion backs down the air inlet diaphragm of ABS pile-up valve assembly and arrives ABS pile-up valve assembly delivery outlet, and last air pressure exports brake chamber and provides brake pressure to brake, as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5.Now the air pressure of the 6th delivery outlet 221 communicates with brake chamber.
During pressurization stages, the 6th delivery outlet 221 is in pressure output state, and the 7th delivery outlet 222 is in depletion of QI and press-fits state, and the first electromagnetic valve controls end 601, public control end 602 and the second electromagnetic valve and controls the equal no power of end 603.
Packing stage:
Connect pressurization stages, if the pressure that now ABS system goes out brake chamber by parameter detecting such as the slip rates of vehicle can not be further added by, be further added by the pressure of air chamber it is possible that problems such as vehicle lockings.ECU can control the public control end 602 of end 603 to the second electromagnetic valve of electromagnetic valve and send holding pressure control signal, coil windings assembly 8 energising near air inlet static iron core 7 end produces magnetic field, iron core 6 dynamic with air inlet static iron core 7 combined effect adhesive air inlet, the dynamic iron core 6 of air inlet overcomes the spring force of air inlet spring 4, moves to air inlet static iron core 7 direction.Now the air pressure at the 3rd air inlet 303 place is by the valve port of air intake valve 2 to the first delivery outlet 304, it is that the 3rd air inlet 303 first delivery outlet 304 first gas outlet 305 second delivery outlet 306 the 7th delivery outlet 222(now the 4th air vent 504 is in cut-off state by the dynamic iron core 6 of air inlet that air pressure flows to path), the air pressure of the 7th delivery outlet 222 withstands the air inlet diaphragm of ABS pile-up valve assembly and closes blowing mouth, and now the 7th delivery outlet 222 of ABS electromagnetic valve has air pressure to export.
Air pressure owing to flowing through the 7th delivery outlet 222 has withstood the air inlet diaphragm of ABS pile-up valve assembly, the air pressure making ABS pile-up valve assembly air inlet is cut off through relay valve, air inlet diaphragm seasonal epidemic pathogens road, cannot exporting to delivery outlet, the air pressure of delivery outlet can not arrive brake chamber.Now the pressure of brake chamber will not be further added by, and is in packing state, as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5.Now the air pressure of the 6th delivery outlet 221 is not communicated with by the air inlet diaphragm of ABS pile-up valve assembly and brake chamber,
During packing stage, the 6th delivery outlet 221 is in pressure output state, and the 7th delivery outlet 222 is in pressure output dress state, and the second electromagnetic valve controls the public control end 602 of end 603 and is in "on" position.
Decompression phase:
Connect packing stage, if now ABS system by the parameter detecting such as the slip rate of vehicle go out the pressure of brake chamber need to reduce time, ECU can control the public control end 602 of end 601 to the first electromagnetic valve and send Decompression Controlling signal, coil windings assembly 8 energising near aerofluxus static iron core 11 end produces magnetic field, iron core 13 dynamic with aerofluxus static iron core 11 combined effect adhesive aerofluxus, the dynamic iron core 13 of aerofluxus overcomes the spring force of exhaust spring 14, the dynamic iron core 13 of aerofluxus moves to aerofluxus static iron core 11 direction, close the air pressure of the 6th air inlet 403, block and carried air pressure to the 6th delivery outlet 221, open drain tap 15 simultaneously.
Now the air pressure of the 6th delivery outlet 221 arrives the 6th air vent 506 by abnormity passage, and the inner passage again through ABS pile-up valve flows to air vent.Its exhaust stream is the 6th delivery outlet 221 the 5th delivery outlet 407 the 4th delivery outlet 406 second gas outlet 405 the 3rd delivery outlet 404 first row QI KOU 501 second exhaust port 502 the 3rd air vent 503 the 6th air vent 506 through path, being discharged by ABS pile-up valve inner passage, the air pressure of the 6th delivery outlet 221 declines.
Air pressure owing to flowing through the 7th delivery outlet 222 has withstood the air inlet diaphragm of ABS pile-up valve, makes the pressure that ABS pile-up valve assembly exports brake chamber to increase.The air pressure decline adding the 6th delivery outlet 221 cannot make the aerofluxus diaphragm of ABS pile-up valve assembly close air vent, the now Exhaust Open of ABS pile-up valve assembly, the air pressure making brake chamber is discharged by the air vent of aerofluxus diaphragm, reach the purpose making brake chamber reduce pressure, as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5.
During decompression phase, the 6th delivery outlet 221 is in pressure decline state, and the 7th delivery outlet 222 is in pressure output dress state, and the second electromagnetic valve controls the public control end 602 of end 603 and the first electromagnetic valve controls end 601 and is in "on" position.
Although below various preferred implementations and feature to the present invention are described, but under the premise without departing from the purpose of the present invention and objective, the present invention can be made many changes, supplement, changes and delete by those of ordinary skill in the art.Above in association with the detailed description that specific embodiments of the invention are done, it is not limitation of the present invention.Every technical spirit according to the present invention, to any simple modification made for any of the above embodiments, all still falls within the scope of technical solution of the present invention.
