Description
Technical field
The present invention relates to a kind of brake radiating device, belong to automobile brake technical field of heat dissipation, be particularly suitable for large-scale load
Heavy cargo car drum brakes radiates.
Background technology
Because drum brakes technology brake force is big, brake reliability is high, cost is relatively low, thus it is large-scale load-carrying goods at present
The topmost brake technique that car adopts, but drum brakes technology also has many shortcomings, such as poor radiation, response speed slow,
The heat fading problem that complex structure etc., wherein poor radiation lead to can have a strong impact on braking effect, leads to many vehicle accidents.Heat
Decline is cannot to be excluded in time and constantly be accumulated due to the substantial amounts of heat of the generation that rubs between brake block and brake drum, when temperature surpasses
When crossing certain numerical value, the coefficient of friction between brake block and brake drum will drastically decline, thus leading to friction effect to weaken, stops
The phenomenon that vehicle speed slows down.In order to avoid heat fading problem, on the one hand can be using cheap water tank fountain cooling method, separately
On the one hand the brake load of brake block and brake drum can be mitigated in the way of using retarder or evb electromotor, thus changing
Kind braking effect.But fountain heat sink is larger due to water tank weight, from hundreds of kilogram to a metric ton, automobile
Load-carrying increased, thus leading to oil consumption also can increase, and needing in transit constantly to supplement water toward in water tank, increasing
The expense of transport；Fountain device is fixed on wheel outer end due to outlet, leads to fin to there is internal-external temperature difference so that braking
Piece is ruptured due to unbalanced stress；Fountain heat sink in the winter time when due to elongated water pipe expose easy in atmosphere
There is freezeout it is impossible to be brake drum water drenching in time, lead to radiating effect to decline, cause vehicle accident.Retarder or
The mode of evb electromotor, due to complex structure.Maintenance difficult, and cost is higher, also uses at present in the radiating of truck
Be not very universal.
For avoiding brake to lead to inside tires temperature rise too high thus causing phenomenon of blowing out, tire pressure also set up by many automobiles at present
And tire temperature detector examining system, when tire pressure and tire temperature reach certain setting numerical value to alarm driver, remind driver to take measures right
Wheel and tire are lowered the temperature.The direct method of measurement in tire pressure and tire temperature detector examining system is that temperature sensor is arranged on automotive wheels
At tyre valve mouth, the temperature of measurement is not exactly accurate, and big by ambient temperature influence of fluctuations.
Heat pipe principle is to utilize sweat cooling, because evaporation takes away substantial amounts of heat so that the two ends temperature difference of heat pipe is very big,
Accelerate the conduction velocity of heat.Heat pipe is hollow structure, and inside is negative pressure state, is filled with suitable low boiling point, volatile liquid
After body, when heat pipe one end is heated, the liquid in pipe evaporates rapidly, and steam flows to the other end under small pressure differential, and
And release heat, regelation becomes liquid, and liquid relies on capillary force to flow back to evaporation ends along tube wall again, so circulation then heat
Can constantly be conducted out.
Patent cn 201833997u discloses a kind of automatic automobile brake drum circulatory cooling system.This system adopts temperature
Sensor sensing temperature information, can select to automatically control or Non-follow control, when be in automatically control when real-time by controller
The brake signal of collection automobile, being judged in conjunction with temperature signal, being decided whether that feed pump and fan are powered, thus realizing automobile
That brakes automatically controls；Non-follow control is then judgement according to driver itself power supply to connect water pump and fan.But should
Technology still uses the mode of fountain to lower the temperature it is impossible to solve water route frozen problem in water pipe during low temperature, and is stopping
Signal control portion is added during car, easily impaired in transportation, and overhaul difficulty.
