The utility model content
The purpose of this utility model is to provide a kind of more safe and reliable drg Pneumatic controller.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of drg Pneumatic controller, and it comprises air source, oil water separator, storage tank, foot brake main valve, booster pump, shutoff valve; Described air source is through the inlet of oil water separator connection storage tank, and the storage tank outlet is through the admission port of two booster pumps of foot brake main valve connection, and the air extractor duct of booster pump is communicated with drg; It also comprises an emergency braking apparatus, and this emergency braking apparatus mainly is made up of emergency brake valve, rapid release valve, energy brake air chamber, brake wheel, urgent booster pump, shuttle valve; Admission port of described shuttle valve is communicated with the air extractor duct of emergency brake valve and is communicated with shutoff valve by urgent booster pump, and another admission port is communicated with the foot brake main valve and is communicated with shutoff valve by urgent booster pump; The admission port of described emergency brake valve is communicated with storage tank, and an one air extractor duct is communicated with rapid release valve and is communicated with brake wheel through rapid release valve, energy brake air chamber, and its another air extractor duct is communicated with the admission port of shuttle valve.
Described emergency brake valve is a two-position four-way valve.
Bypass one atmospheric pressure table between emergency brake valve and rapid release valve.
After adopting such scheme, since the utility model on the brake system of commonly using bypass one by emergency brake valve, rapid release valve, the energy brake air chamber, brake wheel, urgent booster pump, the emergency braking apparatus that shuttle valve etc. are formed, this device has been set up a brake wheel that in case of emergency can be used for reporting dead wheel on the one hand, increased on the other hand one in case of emergency can be on drg the pipeline of booster pump gas transmission, made more than the drg bar vent line, this has increased system reliability greatly, greatly eliminated the potential safety hazard that the brake failure because of engineering truck causes, the safety that has improved vehicle.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the air pressure lines figure of air-pressure brake system that commonly uses;
Fig. 2 is air pressure lines figure of the present utility model.
The specific embodiment
As shown in Figure 2, the utility model is a kind of drg Pneumatic controller, and it comprises air source 1, oil water separator 2, storage tank 3, foot brake main valve 4, booster pump 5, shutoff valve 6 and emergency braking apparatus 7.
Described air source 1 is through the inlet of oil water separator 2 connection storage tanks 3, and storage tank 3 outlets are through the admission port of two booster pumps 5 of foot brake main valve 4 connections, and the air extractor duct of booster pump 5 is communicated with drg 8.The augmented thrust ratio of used booster pump 5 is 1: 16.
Described emergency braking apparatus 7 mainly is made up of emergency brake valve 71, rapid release valve 72, energy brake air chamber 73, brake wheel 74, urgent booster pump 75, shuttle valve 76.Described emergency brake valve 71 is a two-position four-way valve.76 1 admission ports of described shuttle valve are communicated with the air extractor duct of emergency brake valve 71 and are communicated with shutoff valve 6 by urgent booster pump 75, and another admission port is communicated with foot brake main valve 4 and is communicated with shutoff valve 6 by urgent booster pump 75.The admission port of described emergency brake valve 71 is communicated with storage tank 3, an one air extractor duct is communicated with rapid release valve 72 and is communicated with brake wheel 74 through rapid release valve 72, energy brake air chamber 73, so that in emergency circumstances, after the handle 710 of emergency brake valve 71 was pressed, storage tank 3 drove brake wheel 74 actions by emergency brake valve 71, rapid release valve 72, energy brake air chamber 73; Another air extractor duct of emergency brake valve 71 is communicated with the admission port of shuttle valve 76, be used in case of emergency, after the handle 710 of emergency brake valve 71 is pressed, by urgent booster pump 75 to shutoff valve 6 delivery pressures.Supply gas with two booster pumps 5, inefficient braking device 8 is reworked.In addition, bypass one atmospheric pressure table 77 between emergency brake valve 71 and rapid release valve 72.
Principle of work of the present utility model:
(1) braking under the service brake, normal working.It is to realize by foot brake main valve 4 and booster pump 5.When starting vehicle, will be connected red manual handle 710 pull-ups on the emergency brake valve 71 (two-position four-way valve), P-A connects (normally open), 73 inflations of air source 1 supply and exhaust compressed air brake cylinder.Braking during standstill is removed when reaching certain pressure, and at this moment vehicle just can enter normal working.Be applied to normal work.
(2) braking during standstill, the braking under the Parking state.Spring housing by emergency brake valve 71 (two-position four-way valve) and energy brake air chamber 73 realizes.Braking during standstill; In normal operation, after hours, press lower handle 710, P-B connects, and cuts off power system.P-A disconnects the A-T connection simultaneously, and energy brake air chamber 73 is realized bleeder brake, thereby realizes braking during standstill.If handle 710 positions no longer change, vehicle is in the braking during standstill state forever, can park cars very easily, need not select the ground environment of level especially.Need to be applied to the situation of long period Parking.
(3) emergency braking is realized emergency braking under the situation of driving braking failure.Supply with under the entirely ineffective state in service brake or pipeline source of the gas, press red handle 710, P-B connects, and cuts off power system.P-A disconnects the A-T connection simultaneously, and energy brake air chamber 73 is realized bleeder brake, thereby realizes emergency braking.If recover handle 710 original positions then the emergency braking releasing.Chaufeur is pushed emergency stop button rapidly, and the spring housing by emergency brake valve 71 (two-position four-way valve) and energy brake air chamber 73 realizes.Be applied to the situation that service brake was lost efficacy.
Emphasis of the present invention just is: set up an emergency braking apparatus on the brake system of commonly using.
