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 applicable to the heat radiation of large-scale load truck drum brakes.
Background technique
Because drum brakes technology braking force is large, brake reliability is high, cost is also lower, because of but the topmost brake technique that adopts of current large-scale load truck, but drum brakes technology also has many shortcomings, as slow in poor radiation, reaction velocity, complex structure etc., the heat fade problem that wherein poor radiation causes can have a strong impact on braking effect, causes many traffic accidents.Heat fade cannot get rid of in time because friction between brake block and brake drum produces a large amount of heat and constantly accumulate, when temperature exceedes certain numerical value, friction factor between brake block and brake drum will sharply decline, thus causes friction effect to weaken, the phenomenon that brake speed slows down.In order to avoid heat fade problem, cheap water tank with spraying cooling method can be adopted on the one hand, the mode of retarder or EVB motor can be adopted to alleviate the brake load of brake block and brake drum on the other hand, thus improve braking effect.But with spraying cooling device due to water tank weight comparatively large, from hundreds of kilogram to 1,000 kilograms not etc., the load-carrying of automobile increases to some extent, thus causes oil consumption also can strengthen, and needs in transit constantly toward supplementing water in water tank, increases the expense of transport; With spraying device is fixed on wheel outer end due to water outlet, causes radiating fin to there is internal-external temperature difference, and brake block is broken due to unbalanced stress; With spraying cooling device in the winter time time due to elongated water pipe expose easily there is freezeout in atmosphere, cannot be brake drum trickle in time, cause radiating effect to decline, initiation traffic accident.The mode of retarder or EVB motor, due to complex structure.Maintenance difficult, and cost is higher, what also use in the heat radiation of truck at present is not very general.
Cause inside tires temperature rise too high for avoiding brake thus cause phenomenon of blowing out, current many automobiles also set up tire pressure and tire temperature detector examining system, when tire pressure and tire temperature reach certain setting numerical value to alarm driver, driver is reminded to take measures to lower the temperature to wheel and tire.The direct method of measurement in tire pressure and tire temperature detector examining system is that temperature transducer is arranged on auto-tire valve place, and the temperature of measurement is not very accurate, and large by external temperature influence of fluctuations.
Heat pipe principle utilizes sweat cooling, because a large amount of heats is taken away in evaporation, makes the two ends temperature difference of heat pipe very large, accelerate the conduction of velocity of heat.Heat pipe is hollow structure, and inside is negative pressure state, after being filled with low, the volatile liquid of suitable boiling point, when heat pipe one end is heated, the liquid in pipe evaporates rapidly, and steam flows to the other end under small pressure difference, and release heat, regelation becomes liquid, and liquid relies on capillary force to flow back to vaporizing end along tube wall again, and so circulate, 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 senses temperature information, can select automatically to control or Non-follow control, when being in control automatically by the brake signal of controller Real-time Collection automobile, judge in conjunction with temperature signal, determine that whether feed water pump and fan are powered, thus realize the automatic control of braking automobile; Non-follow control is then the power supply connecting water pump and fan according to the judgement of driver self.But the mode of what this technology still adopted is with spraying is lowered the temperature, water route frozen problem in water pipe when cannot solve low temperature, and add signal control portion when braking, easily impaired in transportation process, and maintenance difficulty.
