Detailed description of the invention
As shown in Figure 1, the utility model commercial vehicle uphill starting ancillary system air operated control electromagnetic valve, comprise a two-bit triplet normally closed valve 100, the admission port 3 of described two-bit triplet normally closed valve 100 is for communicating with storage tank 1, its air extractor duct 12 is for communicating with compressed air brake cylinder 20, its exhausr port 19 is for communicating with air, its valve pocket 18 is communicated with air extractor duct 12 by upper valve port 8, communicated with exhausr port 19 by lower valve port 10, when magnet coil 5 powers on, dynamic iron core 6 is changed into by the upper valve port 8 of partition and cuts off lower valve port 10, also comprise a diaphragm valve 200, described diaphragm valve 200 comprises guide's air chamber 7 and air inlet diaphragm 4, described guide's air chamber 7 is communicated with described valve pocket 18 by cutoff port 11, described guide's air chamber 7 is isolated with admission port 3 by described air inlet diaphragm 4, when air inlet diaphragm 4 is in closed condition, admission port 3 can be made to communicate with air extractor duct 12, when air inlet diaphragm 4 is in opening, admission port 3 and air extractor duct 12 can be made to isolate.
Described two-bit triplet normally closed valve 100 also comprises the static iron core 16 and coil spring 9 that coordinate with described dynamic iron core 6, and described static iron core 16, between lower valve port 10 and exhausr port 19, can make iron core 6 cut off upper valve port 8 when described coil spring 9 stretches.
Working process of the present utility model is described in detail below in conjunction with Fig. 2-Fig. 3:
Under off position, as shown in Figure 2, chaufeur can control brake pedal 2 and realize braking applying and release.
Electromagnetic valve does not power on, guide's air chamber 7 communicates with air, again because movable iron core of electromagnetic valve 6 has blocked the passage between admission port 3 and guide's air chamber 7, air inlet diaphragm 4 is caused to be opened under the effect of two-way pressure difference, admission port 3 and air extractor duct 12 communicate, and namely storage tank 1 is communicated by uphill starting aux. control valve with compressed air brake cylinder 20.If now chaufeur steps on brake pedal 2, then the gas in storage tank successfully directly can flow through uphill starting aux. control valve and lead to brake air chamber, thus brake-pressure increases, as Fig. 2 A; If chaufeur lifts brake pedal, the gas of compressed air brake cylinder 20 directly will flow through electromagnetic valve and be discharged in air by the rapid release valve at brake pedal 2 place, realizes braking release, as Fig. 2 B.
In working order, as shown in Figure 3, control unit can realize compressed air brake cylinder 20 pressurize and decompression by Controlling solenoid valve, chaufeur by controlling brake pedal 2, also can realize pressure compensation when compressed air brake cylinder 20 dwell pressure deficiency.
Pressurized state, as Fig. 3 A: electromagnetic valve does not power on, guide's air chamber 7 communicates with air, again because movable iron core of electromagnetic valve 6 has blocked the passage between admission port 3 and guide's air chamber 7, air inlet diaphragm 4 is caused to be opened under the effect of two-way pressure difference, admission port 3 and air extractor duct 12 communicate, and namely storage tank 1 is communicated by uphill starting aux. control valve with compressed air brake cylinder 20.If now chaufeur steps on brake pedal 2, then the gas in storage tank successfully directly can flow through uphill starting aux. control valve and lead to compressed air brake cylinder 20, thus brake-pressure increases.
Packing state, as Fig. 3 B: electromagnetic valve powers on, dynamic iron core 6 moves down blocks lower valve port 10, and the high pressure gas in compressed air brake cylinder 20 enter guide's air chamber 7 back up through valve pocket 18, and air inlet diaphragm 4 moves down and then block air flue A and air flue B under the effect of two-way pressure difference.Therefore the pressure of compressed air brake cylinder 20 remains unchanged.
Pressure compensation, as Fig. 3 C: under packing state, if now brake-pressure is not enough, chaufeur can realize brake-pressure compensation by trampling brake pedal 2.Now chaufeur steps on brake pedal 2, high pressure gas in storage tank 1 enter air flue A, and air inlet diaphragm 4 reopens under the effect of two-way pressure difference, and air flue A is communicated with again with air flue B, gas in storage tank 1 enters compressed air brake cylinder 20, and compressed air brake cylinder 20 is in pressure increases state again.
Decompression state, as Fig. 3 D: electromagnetic valve power-off, the attraction that dynamic iron core 6 loses electromagnetic force moves up under spring force and blocks valve port 8, and guide's air chamber 7 communicates with air, and the high pressure gas in guide's air chamber 7 are discharged by exhausr port 19.Air inlet diaphragm 4 moves up under the effect of two-way pressure difference and then air flue A is communicated with air flue B.The high pressure gas of compressed air brake cylinder 20 are discharged in air by the foot valve at foot brake pedal 2 place via air flue A/B.Along with the pressure gas in compressed air brake cylinder 20 is constantly discharged to air, compressed air brake cylinder 20 is made to be in reduced pressure state.
Uphill starting assisted gas moving electromagnetic valve can pass through electric signal input control pneumatic pipeline, thus realizes the control to brake line.In automobile brake system, uphill starting assists pneumatic Controlling solenoid valve to access brake line with tandem, under normal working, require that uphill starting pilot solenoid valve does not produce any impact to brake system, the pressed gas in brake line freely can bidirectionally pass in and out uphill starting and assist pneumatic Controlling solenoid valve.
The utility model is integrated with diaphragm valve and a two-bit triplet normally closed valve, instead of the structure of original " electromagnetic valve+check valve ", can ensure under solenoid valves state, and chaufeur still can according to actual conditions to compressed air brake cylinder supercharging.In addition, the structure of diaphragm valve can lower the retardance impact of valve body structure on braking air pipe inflation/deflation speed, does not extend the reaction time of service brake.The design of this integral valve only used the functional requirement that a diaphragm valve and two-position three-way valve just achieve system, and it is simple and reasonable, reliable in function, braking are timely.
