The specific embodiment
Accompanying drawing has provided a specific embodiment of the present invention, and the invention will be further described below in conjunction with the drawings and specific embodiments.
By accompanying drawing 1 as can be seen, the present invention is the Pneumatic brake systems of automobile, comprise brake pedal 1, preceding brake cylinder 2, air compressor 9, back brake cylinder 10 and air feed main line 11, its characteristics are: in the automobile air brake system, one air compressor is set plays/stop control system 4, play/stop control system 4 by air compressor and realize air compressor 9 in the working pressure range of setting, the work of intermittence.Control system 4 is to be combined by pressure regulating valve 3, pressure relay 5, relay 6, electromagnetic valve 7 gentle control direction valves 8, and utilize pressure regulating valve 3 and pressure relay 5 rise/to stop air compressor, when air pressure is higher than setting pressure (0.8-1MPa), pressure relay 5 conductings are opened and made to pressure regulating valve 3, at the pressure relay 5 other relays 6 that are provided with, pressure relay 5 forces relay 6 adhesives, thereby makes air compressor 9 dead electricity and quit work; When cylinder air pressure is lower than setting pressure lower limit (0.45-0.65MPa), pressure regulating valve 3 cuts out, make pressure regulating valve 3 air gate off-loads, so that pressure relay 5 disconnects, and relay 6 also disconnects, thereby starting air compressor 9 is adjusted pressure regulating valve and can be adjusted the control presssure upper and lower bound value that sets arbitrarily.And on energy supply major loop 13, be parallel with electromagnetic valve 7 gentle control direction valves 8, utilize electromagnetic valve 7 and gas control direction valve 8 to realize that energy supply main line 13 carries out off-load, blowdown when air compressor 9 quits work, guarantee that air compressor starts under light condition; In time dirt is got rid of simultaneously, to guarantee brake safe.
Its control system is in the energy supply main line 13 between automobile air brake system air feed main line 11 and air compressor 9 and check valve 12, the serial/parallel air brake air compressor by pressure regulating valve 3, pressure relay 5, electromagnetic valve 7 and 8 combinations of gas control direction valve that connects plays/stops control system, the air pressure that is used to guarantee to brake air reservoir is in the working pressure range of setting, the work of intermittence ground, and guarantee that the air brake air compressor starts under light condition.Wherein pressure regulating valve 3 and pressure relay 5 are installed between the braking gas circuit pipeline air feed main line 11, pressure relay 5 is serially connected in after the pressure regulating valve 3, the air pressure that is used for the control air compressor, and play/stop air compressor according to the range of pressure that sets, when air pressure is higher than the setting pressure upper limit (0.8-1MPa), pressure relay 5 conductings are opened and made to pressure regulating valve 3, and pressure relay 5 forces air compressor 9 dead electricity, thereby stops air compressor work; When cylinder air pressure is lower than setting pressure lower limit (0.45-0.65MPa), pressure regulating valve 3 cuts out, and makes pressure regulating valve 3 air gate off-loads, so that pressure relay 5 disconnects, thereby starting air compressor 9, the upper and lower bound value of control presssure is set by adjusting pressure regulating valve.And in electromagnetic valve 7 and 8 aggregate erections of the gas control direction valve energy supply main line 13 between braking gas circuit pipeline air compressor 9 and check valve 12, electromagnetic valve 7 is connected on the energy supply main line 13 with gas control direction valve 8, be used for when air compressor quits work, for carrying out off-load, blowdown in the energy supply loop, guarantee that air compressor starts under light condition.
Principle of work of the present invention is:
When braking air reservoir pressure was lower than 0.45-0.65MPa (optimum value 0.65Mpa), the air extractor duct of pressure regulating valve 3 led directly to atmosphere, and pressure relay 5 disconnects, relay 6 not adhesives, thus start the air compressor motor.This moment electromagnetic valve 7 and 8 all not conductings of gas control direction valve.Along with the air compressor operation, air pressure improves constantly, and when braking air reservoir pressure reached 0.8-1MPa (optimum value 0.8Mpa), the air extractor duct of pressure regulating valve 3 disconnected with atmosphere and communicates with its admission port.Then: pressure relay 5 conductings, relay 6 adhesives, thus air compressor 9 motors are shut down, adjust pressure regulating valve and can adjust the control presssure upper and lower bound value that sets arbitrarily; In addition, electromagnetic valve 7 and the 8 equal conductings of gas control direction valve this moment, the pressed gas of energy supply main line 13 (pipelines that air compressor 9 and check valve are 7) is discharged from the sewage draining exit of dryer 14 through electromagnetic valve and gas control direction valve, make the energy supplying pipeline off-load, guaranteed when starting air compressor once more, air compression function No Load Start makes starting current less.When the 13 exhaust off-loads of energy supply main line, also the sewage in the dryer 14 is discharged.
