Description
Technical field：
The present invention relates to car braking technology field, and in particular to a kind of pneumatic control system of bus brake system system and its
Control method.
Background technology：
At present, the brakes of car typically uses double-loop air brakes.Before starting, inflating pump is carried out to gas receiver
Inflation, carries out off-load, the enable signal of inflating pump receiving dryer, which is stopped, (beats when reaching drier and reaching off-load air pressure
Air pump starts general acquiescence work 8 minutes for the first time).When baroceptor is less than the atmospheric pressure value set on gas receiver, inflate
The signal that pump receives entire car controller starts to be actuated for inflating.Present drier substantially be that mechanical pressure is opened
Close, when the pressure of gas receiver not yet reaches off-load air pressure in some cases, drier is with regard to having reached off-load air pressure and having been unloaded
Lotus, now the pressure of gas receiver is too small, and inflating pump frequent starting and some potential safety hazards can be caused to exist.
The content of the invention：
The present invention is to provide a kind of air pressure control of bus brake system system to solve the above-mentioned problems of the prior art
System and its control method processed.
The technical solution adopted in the present invention has：A kind of pneumatic control system of bus brake system system, including it is inflating pump, cold
Condenser, drier, baroceptor, four-loop protection valve, preceding braking gas receiver, rear braking gas receiver and regenerating tank, it is described cold
One end of condenser is connected with inflating pump, and the other end is connected with drier, and drier is connected with regenerating tank, and the one of four-loop protection valve
End is connected with drier, braking gas receiver and rear braking gas receiver before other end connection, before two baroceptors are connected to
Brake on gas receiver and rear braking gas receiver.
Further, the drier is the drier of electric-controlled type.
The present invention provides a kind of air pressure control method of bus brake system system, including
1) when vehicle starts for the first time, vehicle control unit controls inflating pump acquiescence work 8 minutes, when baroceptor senses
When the pressure of preceding braking gas receiver and rear braking gas receiver reaches the 0.8Bar pressure of default, vehicle control unit controls are dried
Device off-load 10s, regenerating tank carry out blowback 10s；
2) after vehicle starts for the first time, the pressure of braking gas receiver and rear braking gas receiver before baroceptor senses
During less than default 0.55Bar alarm pressures, vehicle control unit controls inflate pump startup, start to inflate；
3) after vehicle starts for the first time, inflate pump work when, braking gas receiver and after system before baroceptor senses
When the pressure of dynamic gas receiver is more than 0.8Bar, vehicle control unit controls drier off-load 10s, while vehicle control unit controls are inflated
Pump is stopped.
The present invention has the advantages that：The closing of inflating pump and to open all be air pressure according to gas receiver in the present invention
Sensor is controlled, and the off-load of drier is also to be controlled according to the pressure of gas receiver, such pneumatic control system meeting
It is more accurate, be not in that gas receiver pressure is not up to, and the situation of drier off-load occurs.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention discloses a kind of pneumatic control system of bus brake system system, including inflating pump 1, condenser
2nd, drier 3, baroceptor 4, four-loop protection valve 5, preceding braking gas receiver 6, rear braking gas receiver 7 and regenerating tank 8, condensation
One end of device 2 is connected with inflating pump 1, and the other end is connected with drier 3, and the back blow port of drier 3 is connected to regenerating tank 8, four times
One end of road protection valve 5 is connected with drier 3, braking gas receiver 6 and rear braking gas receiver 7 before other end connection；Two air pressure transmissions
Before sensor 4 is connected on braking gas receiver 6 and rear braking gas receiver 7.
Baroceptor 4 in the present invention is high-precision baroceptor, for sensing preceding braking gas receiver 6 and rear system
The pressure of dynamic gas receiver 7 is simultaneously sent to entire car controller.It is when the air pressure minimum of two gas receivers is more than off-load air pressure, then whole
Vehicle controller control inflating pump 1 is stopped, drier off-load.When the air pressure minimum of two gas receivers is less than what system was set
During alarm pressure, vehicle control unit controls inflating pump 1 is started working.
Drier 3 is the drier of electric-controlled type, and traditional mechanical type pressing is substituted for magnetic valve in drier 3 in the present invention
Power switchs, and other structures are constant.Magnetic valve is normally closed type 2/2-way magnetic valve, when entire car controller controls according to pressure unloading
During drier off-load, built-in solenoid valves off-load, regenerating tank 8 carries out the blowback of certain time, and then magnetic valve powers off, place
In closed mode.
Entire car controller receives the signal from baroceptor 4, then controls inflating pump 1 and drier 3 to work.
Inflating pump 1, condenser 2, four-loop protection valve 5 in the present invention, preceding braking gas receiver 6, rear braking gas receiver 7,
It is the operation principle of regenerating tank 8 and the inflating pump in prior art microbus air braking system, condenser, four-loop protection valve, preceding
Braking gas receiver, braking gas receiver, regenerating tank operation principle are identical afterwards, therefore no longer the present invention is repeated.
The control method of the pneumatic control system of above-mentioned bus brake system system, including：
1) when vehicle starts for the first time, vehicle control unit controls inflating pump 1 gives tacit consent to work 8 minutes, when baroceptor 4 is felt
When braking gas receiver 6 reaches the 0.8Bar pressure of default with the rear pressure for braking gas receiver 7 before answering, vehicle control unit controls
The off-load 10s of drier 3, regenerating tank 8 carry out blowback 10s；
2) after vehicle starts for the first time, braking gas receiver 6 and rear braking gas receiver 7 before baroceptor 4 senses
When pressure is less than default 0.55Bar alarm pressures, vehicle control unit controls inflating pump 1 starts, and starts to inflate；
3) vehicle for the first time start after, inflating pump 1 work when, when baroceptor 4 sense before braking gas receiver 6 with after
When the pressure of braking gas receiver 7 is more than 0.8Bar, the off-load 10s of vehicle control unit controls drier 3, while vehicle control unit controls
Inflating pump 1 is stopped.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
