Preferentially give brakes QI invigorating rather than force cooling brake.
It is illustrated in figure 8 the operation principle schematic diagram of the application：
Detection means 101 is detected whether as cross-country run state, if cross-country run state, unlatching auxiliary sky after vehicle launch
Press, and connect to the pipeline of brakes QI invigorating, if road running state, detection means 101 has detected whether braking
Device exceedes design temperature, if it exceeds the temperature, opens auxiliary air compressor machine and three position five-way valve is connected to overheated brake
The pipeline of blowing radiating.
If neither cross-country status, again all normally, then three position five-way valve is in middle position closed state, storage to brake temperature
Inflator pressurize.After regulator off-load, or after the brake of high temperature is all cooled to normal temperature, by control module 102
Close auxiliary air compressor machine.
The control module 102 of the present invention may be set to automatic mode and manual both of which
1）Automatic mode：Vehicle Highway is travelled and the switching between cross-country run state.
Detected according to vehicle running state first, select to open or be not turned on 103 air generating means, and given birth to for air
Into the air-flow strike angle valve in device 103（Can be, but not limited to three position five-way valve）Select airflow direction.Control module 102
According to each the brake temperature information collected, brake temperature is determined whether higher than set temperature value, if above setting temperature
Angle value, then open air generating means 103 and work, and opens one or more blowing controlling switch, causes air flow through pipeline
Brake is transferred to, cooling down is carried out, after brake is without the need for cooling down or being sufficiently cool, closing air generation fills 103 and puts and blow
Wind controlling switch, so circulates work；
2）Manual mode：Manual mode arranges three switches in driver's cabin, and respectively QI invigorating switch, cooling switchs and force to close
Make and break is closed.
When QI invigorating switch is opened, control module 102 exits automatic control mode, and gas flow controls Vavle switching to QI invigorating
Station, no matter whether brake temperature is too high, and apparatus of the present invention are only carried out to the work of brakes inflation, and this is switched for one
A little special operation conditions, such as brakes air pressure are too low and when repairing temporarily without Faville.
When cooling switch is opened, controller exits automatic control mode, and gas flow controls Vavle switching to air-cooled station,
No matter whether brakes air pressure is sufficient, all only carries out pressure cooling to brake and is not braked system QI invigorating.This switch
For some special operation conditions, such as brake high temperature and tire pressure is too high is badly in need of stopping to brake cooling etc..
When QI invigorating switchs and cool down switch unlatching simultaneously, automatic control mode can be started：Positive closing is switched, and is used for
The positive closing of control apparatus of the present invention.This is switched for not enough power supplies such as electrical malfunctions, or other need to close and are somebody's turn to do
The special operation condition of device.
