Embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to embodiment to this hair
It is bright to be described in further detail.
Fig. 1 is refer to, it is of the invention from cold brake, including the friction plate 4, two of brake drum 1, two and of brake-shoe 301
302 and two brake actuators 2, brake actuator 2 includes but is not limited to wheel cylinder, camshaft actuator or wedge-type braking and promoted
Dynamic device 2.Two friction plates 4 post and fix with the inwall of brake drum 1 to be connected, and two brake-shoes 301 and 302 are in brake actuation
In the presence of device 2 can expansion and contraction, to cause brake-shoe 301 and 302 to be contacted under on-position with friction plate 4, non-
On-position separates with friction plate 4, and the structures of two brake-shoes 301 and 302 is cavity structure, two brake-shoes 301 and 302
Preceding surface be equipped with the inlet 6 and liquid outlet 7 turned on cavity, inlet 6 and liquid outlet 7 are connected by flexible conduit respectively
Connect cooling system, using flexible conduit have it is stronger it is anti-deflect, dilatation ability and shock resistance, be easily installed and adjust
Section.Cooling system is used to convey refrigerant into cavity structure.The effect of refrigerant is exchanged heat with the inwall of cavity structure, therefore
It can use any one that there is the suitable fluid of capacity of heat transmission.Such as water or conventional various motor vehicles can be used cold
But liquid etc..Cooling system includes water pump 8, cooling liquid container 11 and temperature control unit, and water pump 8 and cooling liquid container 11 pass through pipe
The inlet 6 and liquid outlet 7 of road and cavity structure connect；Temperature control unit includes controller 10, temperature sensor 5 and set
Semiconductor chilling plate 9 in cooling liquid container 11, temperature sensor 5 include the thermocouple 12 of temperature sensor, TEMP
Device 5 is used for the temperature for sensing coolant, and controller 10 is communicated to connect with temperature sensor 5 and semiconductor chilling plate 9, controlled respectively
Device 10 also communicates to connect with water pump 8.Can on the pipeline between inlet 6, liquid outlet 7 or cooling system mounting temperature sensor
5.Although it should be appreciated that show a temperature sensor in the embodiment of the present invention, according to the use needs of reality,
The quantity of temperature sensor can be multiple, and multiple temperature sensors can be arranged on inlet 6, liquid outlet 7 and cooling system
Multiple positions in road under the overall leadership.During self cooling brake, the piston of wheel cylinder is mobile laterally respectively to promote two brakings
Hoof 301 and 302 moves radially, and then is contacted respectively with both sides friction plate 4, and brake-shoe 301 and 302 produces friction with friction plate 4
And substantial amounts of heat is produced, frictional heat caused by the refrigerant absorption in the cavity structure of brake-shoe 301 and 302, and to brake-shoe 301
Cooled down with 302, refrigerant flows out brake-shoe 301 and 302 by liquid outlet 7 afterwards, the temperature rise that now liquid outlet 7 flows out
Refrigerant flow through temperature sensor 5, if thermocouple 12 when temperature is more than a default value in temperature sensor 5 senses coolant
Temperature is raised, and after temperature sensor 5 obtains refrigerant temperature signal, signal transmission is fed back to the controller 10 in cooling system,
The signal that one side controller 10 obtains temperature sensor 5 amplifies, then transmits a signal to power amplifier, drives cooling liquid container 11
In semiconductor chilling plate 9 work, so as to realize the control to coolant temperature in cooling system；Another aspect controller 10 carries
The power of high water pump 8, increases coolant rate, accelerates brake-shoe 301 and 302 and cools down, complete cooling work, water pump 8 can be with
It is arranged on pipeline, can also be arranged in water tank in either cavity structure.From after cold brake stops braking, brake-shoe
301 and 302 separate with friction plate 4, and brake-shoe 301 and 302 stops producing heat with friction plate 4, and now liquid outlet 7 flows out cold
But liquid temperature degree reduces, and when the sensing of thermocouple 12 coolant temperature in temperature sensor 5 is reduced to below default value, temperature passes
After sensor 5 obtains signal, signal transmission is fed back into controller 10, the letter that one side controller 10 obtains temperature sensor 5
Number amplification, then transmits a signal to power amplifier, semiconductor chilling plate 9 is worked phased out；Another aspect controller 10 reduces water
The power of pump 8, reduces coolant rate, saves energy.
