Abstract
The utility model discloses a kind of drg pneumatic control system, comprise air compressor, air receiver, the first pressure regulating valve, the second pressure regulating valve, brake activation valve, front rapid release valve and rear relay valve; In the gas circuit that described air receiver is connected with the first admission port of described brake activation valve, the first pressure regulating valve is installed; In gas circuit before the second admission port of described air receiver and described brake activation valve and the admission port place of connecting of described rear relay valve, the second pressure regulating valve is installed; The first air extractor duct of described brake activation valve is connected with the admission port of front rapid release valve; Two air extractor ducts of described front rapid release valve are respectively connected with a front compressed air brake cylinder; The second air extractor duct of described brake activation valve is connected with the control mouth of described rear relay valve; Two outlets of described rear relay valve are respectively connected with compressed air brake cylinder after.The utility model carries out pressure adjusting by increase limiting valve at air receiver air extractor duct place, reduces the volume of air receiver, solves inconvenience and the problem difficult and that other components and parts are integrated safeguarded.
Description
Technical field
The utility model relates to automobile brake control field, is specifically related to a kind of drg pneumatic control system.
Background technology
The Pneumatic braking system of automobile is to use shrinkage air as propulsion source, and converts pressure to machine thrust, and wheel is braked.Chaufeur can, by the stroke of control pedal, just, by adjusting the size of gaseous tension, obtain consistent braking force, obtains certain braking force.Pneumatic braking system is the modal pattern of power brake system, due to can obtain the connecting device structure of braking driving system between larger braking and drive force and main car and the trailer being dragged and train-type vehicle simple, connect and disconnect all easily, being therefore widely used in total mass is on goods carrying vehicle, cross country car and passenger vehicle more than 4t.Compression air brake major advantage is for handling light, reliable operation, easy break-down, maintenance are not convenient; In addition, its source of the gas, except for braking, can also install for other.
Pneumatic braking system need to use several air receivers to carry out energy storage, the anticyclonic pressure that general light truck air receiver adopts is 8bar, the anticyclonic pressure that medium and heavy truck air receiver adopts is 9bar, and in advanced heavy duty truck abroad, the anticyclonic pressure of air receiver can reach 12.5bar.Day by day require under the background strict, standard constantly changes in Chinese automobile discharge, light truck need to install SCR urea tank mostly additional, the volume of fuel tank is also increasing simultaneously, so just cause more and more less that air receiver becomes at the installing space of frame outside, if air receiver is arranged on to frame inside, easily causes and safeguard that inconvenience, difficult and other components and parts carry out integrated problem.
Utility model content
The purpose of this utility model is to provide a kind of drg pneumatic control system, meet braking performance of vehicle meet GB require basis on, reduce the volume of air receiver, make the mounting arrangements of air receiver on vehicle frame simpler, solve inconvenience and the problem difficult and that other components and parts are integrated safeguarded.
For achieving the above object, the utility model provides following technical scheme:
A kind of drg pneumatic control system, comprises air compressor, air receiver, the first pressure regulating valve, the second pressure regulating valve, brake activation valve, front rapid release valve and rear relay valve; The outlet of described air compressor is connected with the admission port of described air receiver; In the gas circuit that the first air extractor duct of described air receiver is connected with the first admission port of described brake activation valve, the first pressure regulating valve is installed; In gas circuit before the admission port place of connecting of the second air extractor duct of described air receiver and the second admission port of described brake activation valve and described rear relay valve, the second pressure regulating valve is installed; The first air extractor duct of described brake activation valve is connected with the admission port of front rapid release valve; Two air extractor ducts of described front rapid release valve are respectively connected with a front compressed air brake cylinder; The second air extractor duct of described brake activation valve is connected with the control mouth of described rear relay valve; Two outlets of described rear relay valve are respectively connected with compressed air brake cylinder after.
Preferably, described air receiver comprises main air reservoir, front braking air receiver and rear braking air receiver, the admission port of described main air reservoir is connected as the admission port of described air receiver and the outlet of described air compressor, the air extractor duct of described main air reservoir is connected with the admission port of front braking air receiver and the admission port of rear braking air receiver, the air extractor duct of described front braking air receiver is connected as the first air extractor duct of described air receiver and the first admission port of described brake activation valve, the air extractor duct of described rear braking air receiver is connected as the second air extractor duct of described air receiver and the second admission port of described brake activation valve.
Preferably, the anticyclonic pressure of described front braking air receiver and rear braking air receiver is set to 10bar.
Preferably, the air extractor duct of described main air reservoir through the admission port of double loop protective valve and described front braking air receiver and described after brake air receiver admission port be connected.
Preferably, the outlet drying device of described air compressor is connected with the admission port of described air receiver.
The beneficial effects of the utility model are:
Drg pneumatic control system provided by the utility model, meet braking performance of vehicle meet GB require basis on, by increasing the pressure of air receiver inside, and on each air receiver outlet pipe, increase limiting valve and carry out pressure adjusting, the gas consumption that can make to be delivered to drg through the adjusting of limiting valve with limiting valve is not installed before identical.Air receiver pressure increase the volume that can reduce air receiver, make the mounting arrangements of air receiver on vehicle frame simpler, solve inconvenience and the problem difficult and that other components and parts are integrated safeguarded.
