Lower mask body introduces the control process of this device:
Pressurized state: braking force is greater than electric braking force needed for the electric engineering car, when namely needing air brake power braking force braked as a supplement, the analog signals that proportion electro-magnet 1 inputs increases (current signal of such as 4mA ~ 20mA or the voltage signal of 0V ~ 24V), proportion electro-magnet 1 converts this electric signal to displacement signal, produce positive-displacement (displacement downward in Fig. 1), promote valve rod 6 to move down, make exhaust plug 62 shutoff exhaust valve port 22, air feed spool 61 departs from air feed valve port 21, namely inlet chamber 3 is communicated with outlet chamber 4, outlet chamber 4 and discharge chamber 5 are isolated.Now, the high pressure air that Air compressor exports flows into air brake equipment through air inlet pipe 31, inlet chamber 3, outlet chamber 4 and freeing pipe 41, realizes the supercharging of air brake equipment.
Decompression state: braking force is less than electric braking force needed for the electric engineering car, when without the need to air brake power, braking force is braked as a supplement, the analog signals that proportion electro-magnet 1 inputs reduces, proportion electro-magnet 1 produces reverse displacement (in Fig. 1 displacement) upwards, band ovable valve stem 6 moves up, make exhaust plug 62 depart from exhaust valve port 22, air feed spool 61 shutoff air feed valve port 21, namely inlet chamber 3 is isolated with outlet chamber 4, outlet chamber 4 is communicated with discharge chamber 5.Now, the air of air brake equipment flows into air through freeing pipe 41, outlet chamber 4, valve port of giving vent to anger, discharge chamber 5 and freeing pipe 51, realizes the decompression of air brake equipment.

Other concrete structures of above-mentioned air-brake controlling device can also be set further.
In another kind of detailed description of the invention, as shown in Figure 1 to Figure 3, above-mentioned air-brake controlling device can also comprise pressure feedback chamber 7, pressure feedback chamber 7 is communicated with freeing pipe 41 by feedback pipe 73, valve rod 6 runs through pressure feedback chamber 7, and top, pressure feedback chamber 7 is connected with proportion electro-magnet 1 by elastomeric element 8; When the pressure in pressure feedback chamber 7 equals the thrust of proportion electro-magnet 1, air feed spool 61 shutoff air feed valve port 21, exhaust plug 62 shutoff exhaust valve port 22.
In concrete scheme, the first elastic plate 71 is provided with in valve body 2, the top board of discharge chamber 5 is the second elastic plate 72, first elastic plate 71 is all fixedly connected with valve body 2 inwall with the perisporium of the second elastic plate 72, valve rod 6 runs through the middle part of the first elastic plate 71 and the second elastic plate 72, and the first elastic plate 71, second elastic plate 72 and valve body 2 inwall three surround pressure feedback chamber 7.
Adopt this structure, as shown in Figure 1, when proportion electro-magnet 1 produces positive-displacement, promote valve rod 6 to move down, open air feed valve port 21, close while exhaust valve port 22, make the middle part of the first elastic plate 71 and the second elastic plate 72 produce downward displacement, namely pressure feedback chamber 7 produces downward tensile deformation.In pressurization, a compressed-air actuated part in freeing pipe 41 flows into air brake equipment, another part is by feedback pipe 73 feed pressure feedback cavity 7, the pressure of inside, pressure feedback chamber 7 is constantly increased, when the pressure increase in pressure feedback chamber 7 equals the downward thrust of proportion electro-magnet 1 to its thrust upwards, promote the first elastic plate 71, the center of the second elastic plate 72 moves up, until the first elastic plate 71, second elastic plate 72 entirety returns to horizontality, as shown in Figure 3, now air feed spool 61 shutoff air feed valve port 21, exhaust plug 62 shutoff exhaust valve port 22, like this, air pressure in air brake equipment keeps current constant, namely voltage stabilizing state during supercharging is in.
In like manner, as shown in Figure 2, when ratio electromagnet produces reverse displacement, promote valve rod 6 to move up, while closing air feed valve port 21, opening exhaust valve port 22, make the middle part generation displacement upwards of the first elastic plate 71 and the second elastic plate 72, namely pressure feedback chamber 7 entirety produces tensile deformation upwards.In decompression process, a pressurized air part in freeing pipe 41 flows into discharge chamber 5, another part is by feedback pipe 73 feed pressure feedback cavity 7, the pressure of inside, pressure feedback chamber 7 is constantly increased, when the pressure increase in pressure feedback chamber 7 equals proportion electro-magnet 1 thrust upwards to its downward thrust, promote the first elastic plate 71, the center of the second elastic plate 72 moves up and down, until the first elastic plate 71, second elastic plate 72 entirety returns to horizontality, as shown in Figure 3, now air feed spool 61 shutoff air feed valve port 21, exhaust plug 62 shutoff exhaust valve port 22, like this, air pressure in air brake equipment keeps current constant, namely voltage stabilizing state during decompression is in.
As can be seen here, the air-brake controlling device in above-mentioned employing pressure feedback chamber 7 can realize automatic voltage regulation in the process of air brake, ensures the working stability of air brake.Can expect, above-mentioned pressure feedback chamber 7 is not limited in said structure, such as, can arrange the first dividing plate and second partition in valve body 2, the two all with the perisporium sliding block joint of valve body 2, the first dividing plate, second partition and valve body 2 internal perisporium surround above-mentioned pressure feedback chamber 7.Adopt this structure, automatic voltage regulation can be realized in the process of air brake equally.But this pressure feedback chamber 7 relates to the Gravity Problem of the first dividing plate, second partition, therefore, the elasticity modulus for elastomeric element 8 has stricter requirement, and proportion electro-magnet 1 is stressed comparatively complicated.
In concrete scheme, above-mentioned elastomeric element 8 can be specially spring.Adopt spring to feed back strong and proportion electro-magnet 1 as elastomeric element 8 Bonding pressure, the working stability of air-brake controlling device can be ensured, and there is lower-cost feature.Certainly, this elastomeric element 8 can also adopt other elastomeric materials such as rubber.
In addition, above-mentioned first elastic plate 71, second elastic plate 72 can be rubber plate.Rubber plate has that deflection is comparatively large, the good advantage of toughness, therefore it can be used as the elastic plate in pressure feedback chamber 7 can extend the service life of air-brake controlling device.Certainly, above-mentioned two elastic plates can also adopt other materials.
In another kind of detailed description of the invention, armature 11 bottom of aforementioned proportion electromagnet 1 can be connected with connecting rod 12 and piston 13, and elastomeric element 8 is located at piston 13 bottom.
Adopt this structure, in working process, first the thrust of electromagnet pass to connecting rod 12, and the displacement of connecting rod 12 drives piston 13 to slide at valve body 2 inwall, and the displacement of piston 13 drives the parts such as elastomeric element 8, valve rod 6 to move again.Due to the periphery wall of piston 13 and the internal perisporium sliding connection of valve body 2, therefore piston 13 has certain directional tagging in moving process, thus ensure that the parts such as elastomeric element 8, valve rod 6 can move along the central axis of valve body 2, avoid valve rod 6 banking motion to cause air feed valve port 21 or exhaust valve port 22 to there is the generation of the wild effects such as gas leakage, ensure the working stability of air-brake controlling device further.

Adopt this structure, make the pressure that above-mentioned cavity remains identical with barometric pressure, avoid because the first elastic plate 71 causes the pressure of this chamber to change in compression and stretching, thus avoid, because pressure change applies extra pressure to elastomeric element 8, ensureing working stability and the reliability of air-brake controlling device.
In further scheme, as shown in Figure 1, valve body 2 is provided with the second air extractor vent 24, second air extractor vent 24 and is communicated with air on the cavity wall surrounded with both pistons 13.
Similarly, this structure can make the pressure of this chamber be always barometric pressure, avoid because piston 13 changes moving up and down in process the pressure causing this chamber, thus avoid applying extra pressure to piston 13, improve the functional reliability of air-brake controlling device.
