Adjustable electrical generator 2 is excitation generator, can be controlled the electric energy generated of stator by the voltage changing rotor.
High power capacitor 5 carries the electric current of coming temporarily to store by from controller 19, treats high-speed centrifugal fan 6 slowly approach exhaustion.
High-speed centrifugal fan 6 has two kinds of installation methods:
A by a Large-power High-Speed centrifugal blower 6 by support installing above vehicle frame 1, air outlet is connected with front steam line 7 and rear steam line 8 simultaneously;
B is installed on above brake disc 11 by four low power high-speed centrifugal fans by support respectively, and air outlet is directly connected with U-shaped multihole nozzle 9.
When a Large-power High-Speed centrifugal blower 6 is installed, the air-flow that needs front steam line 7 and rear steam line 8 to be produced by blower fan while be evenly transported to the inside of each U-shaped multihole nozzle 9; Respectively on four brake discs 11 install four low power high-speed centrifugal fans 6 time, then do not need front steam line 7 and rear steam line 8.
U-shaped multihole nozzle 9 has an air inlet pipe and two freeing pipes, the opposite of two freeing pipes has multiple deflation hole, U-shaped multihole nozzle 9 is by the edge of support installing in brake disc 11, one of them freeing pipe extends in the outside at wheel hub 10 edge, another freeing pipe penetrates brake disc 11 and extends to the inside at wheel hub 10 edge, the centre of two brake shoe pivot shafts, and deflation hole air-flow out inside and outside can be blown to wheel hub 10 and be reached down quench.
The approach that controller 19 receives radiated signal has three kinds:
A is received by the inductor 17 be arranged in the middle of brake pedal 16, and when sensing that the pin of chaufeur touches brake pedal, inductor 17 now needs heat radiation by signal wire (SW) 18 notification controller 19 wheel hub 10;
B is received by the inductor 17 of brake connecting lever contact, and when sensing that brake connecting lever leaves inductor, inductor 17 now needs heat radiation by signal wire (SW) 18 notification controller 19 wheel hub 10;
C, when chaufeur is braked, directly now needs heat radiation by signal wire (SW) 18 notification controller 19 wheel hub 10 by BK Brake Switch.
The major part of controller 19 and function:
What the inside of a controller 19 was installed has intelligent chip, can receive the instruction of inductor 17 or BK Brake Switch, controls adjustable electrical generator 2 and high power capacitor 5 completes required program;
When b intelligent chip receives the signal braked, control large power triode, the electric current that start-up capacitance 20 stores be supplied to the rotor of adjustable electrical generator 2;
After the rotor energising of c adjustable electrical generator 2, generating is started under the driving of back axle 13, electric current is supplied to high power capacitor 5 and start-up capacitance 20 by controller 19, and Large-power High-Speed centrifugal blower 6 or four small power high speed centrifugal blowers 6 can obtain electric current simultaneously and start acting;
D is while high-speed centrifugal fan 6 consumes high power capacitor 5 electricity, and intelligent chip detects that the charge capacity of high power capacitor 5 has reached the upper limit, intelligent chip controls the delivery of large power triode reduction to high power capacitor 5;
E intelligent chip can by not used up for high power capacitor 5 another part electric current, connect high-power resistance by electromagnetism condenser to be consumed, make adjustable electrical generator 2 pairs of back axles 13 produce certain resistance, the speed of a motor vehicle is slowed down, reduce the friction of brake facing to wheel hub 10;
F is when inductor 17 or BK Brake Switch stop the instruction of intelligent chip, and intelligent chip controls aerotron and stops the rotor of start-up capacitance 20 pairs of adjustable electrical generator 2 to power, and electrical generator stops generating getting back to light condition;
After j adjustable electrical generator 2 stops generating, rectifier can cut off the backflow of electric current, and high power capacitor 5 can continue to power 10-20 minutes to high-speed centrifugal fan 6.
Detailed description of the invention
According to the air-cooled cooling system of the invention described above automotive hub electronics in application process, the right crus of diaphragm of automobile chaufeur when needing to slow down touches brake pedal rapidly, inductor or BK Brake Switch start to send work order to controller, when intelligent chip receives the signal braked, control large power triode, the electric current that start-up capacitance stores is supplied to the rotor of adjustable electrical generator, after the rotor energising of adjustable electrical generator, generating is started under the driving of back axle, electric current is supplied to high power capacitor and start-up capacitance by controller, high-speed centrifugal fan also obtains electric current simultaneously and starts acting, the air-flow that blower fan produces by front steam line and rear steam line is evenly transported to the inside of each U-shaped multihole nozzle simultaneously, deflation hole air-flow out can reach down quench to wheel hub, while high-speed centrifugal fan consumes high power capacitor electricity, intelligent chip detects that the charge capacity of high power capacitor reaches the upper limit, intelligent chip controls the delivery of large power triode reduction to high power capacitor, intelligent chip is by not used up for high power capacitor another part electric current, connect high-power resistance by electromagnetism condenser to be consumed, adjustable electrical generator is made to produce certain resistance to back axle, the speed of a motor vehicle is slowed down, reduce brake facing to the friction of wheel hub, when automobile brake is complete, inductor or BK Brake Switch stop the instruction of intelligent chip, intelligent chip controls aerotron and stops the rotor of start-up capacitance to adjustable electrical generator to power, electrical generator stops generating getting back to light condition, high power capacitor continues to power 10-20 minutes to high-speed centrifugal fan, wheel hub gets back to normal temperature fast.
