Abstract
The utility model provides a vehicle brake drum automatically cooling system, includes the water tank and installs at the peripheral compulsory refrigerating plant of brake drum, force refrigerating plant to connect gradually by thermoswitch, solenoid valve and shower nozzle and constitute, and the shower nozzle passes through pipeline and water tank intercommunication. The utility model discloses a many shower nozzles to every shower nozzle can autonomous working, and along with the brake drum temperature constantly risees, the cooling of brake drum has effectively been guaranteed to the increase in volume of work shower nozzle, and the less water yield that flows to the road surface, has guaranteed the in -process of driving a vehicle winter, the security of traveling of back row vehicle.
Description
Technical field
The utility model belongs to automobile supplementary security system, particularly a kind of automobile brake drum automatic cooling system, and this system, for the brake wheel of commercial vehicle, can make the brake wheel being in braking mode for a long time be cooled fast.
Background technology
There are many mountainous regions in China, and mountain highway exists a lot of long descending section.When such road uphill/downhill travels, require that automobile has enough continuous braking abilities, ensure that automobile its service brake at the end of descent run also has enough deceleration and stopping performancies.The statistics of hill path traffic accident shows, quite most of traffic accident due to service brake actuator temperature after automobile long and steep downgrade too high and to lose or part loses braking potential and causes.So for medium-sized, heavy wrecker truck and passenger vehicle, should take the necessary measures when long and steep downgrade and ensure that brake temperature is no more than limit value.
As one of measure solving brake overheating: China's mountain area passenger vehicle is conventional trickle method at present.Namely on passenger vehicle, separately install a water tank additional, mounting spray head outside the brake wheel of each wheel, guides to water in braking.The rotating switch when descent run, is poured water on wheel braking drum by shower nozzle, break drum temperature is remained on and has in the scope of effectual brake force.
But there is following defect in this kind of method: 1, in braking procedure, shower nozzle relies on Non-follow control, and chaufeur is difficult to judge break drum temperature value.2, injection flow rate is fixed, if very few being difficult to of spraying water makes brake wheel effective temperature-reducing; If injection flow rate is too much, not only wastes cooling water expansion tank, cooling water flow also can be made to ground, subsequent vehicle is travelled cause potential safety hazard in the winter time.
Summary of the invention
For the defect of traditional braking drum cooling mechanism, the utility model provides a kind of automobile brake drum automatic cooling system, this system can regulate injection flow rate automatically according to break drum temperature, thus ensure that good cooling performance, and on the impact of rear car when decreasing winter driving.
In order to realize above-mentioned task, the utility model adopts following technical scheme:
A kind of automobile brake drum automatic cooling system, comprises water tank and the forced refrigeration device being arranged on brake wheel periphery; Described forced refrigeration device is connected to form successively by thermoresponsive switch, electromagnetic valve and shower nozzle, and shower nozzle is communicated with water tank by pipeline.
Above-mentioned brake wheel periphery arranges three forced refrigeration devices, three shower nozzles of three forced refrigeration devices by Bracket setting outside brake wheel, and each shower nozzle by pipeline be connected with water tank respectively, each shower nozzle passes through solenoid control by the thermoresponsive switch of correspondence.
Above-mentioned three shower nozzles are evenly arranged on outside brake wheel.
Compared with prior art, the utility model has the advantage of: 1, organize forced refrigeration device arranging of brake wheel periphery more, automatically can regulate injection flow rate according to break drum temperature, thus ensure that good cooling performance.2, many shower nozzles of many group forced refrigeration devices can work alone.3, along with break drum temperature constantly raises, the quantity of work shower nozzle increases, and effectively ensure that the cooling of brake wheel, and decreases the water yield flow on road surface, ensure that the driving safety of row's vehicle after in winter driving process.

Detailed description of the invention
As shown in Figure 1, a kind of automobile brake drum automatic cooling system, is made up of water tank 1, main valve 2 and three groups of forced refrigeration devices.Wherein, the first electromagnetic valve 3, first shower nozzle 4 and the first thermoresponsive switch 5 are first group of forced refrigeration device.Second electromagnetic valve 6, second shower nozzle 7 and the second thermoresponsive switch 8 are second group of forced refrigeration device.3rd electromagnetic valve 9, the 3rd shower nozzle 10 and the 3rd thermoresponsive switch 11 are the 3rd group of forced refrigeration device.In order to make brake wheel cooling in braking procedure, evenly, the shower nozzle in three groups of forced cooling devices is evenly arranged at outside brake wheel, and is fixed on automobile chassis frame.Each shower nozzle is all communicated with water tank 1 by pipeline 13.
At vehicle in the process of moving, the temperature of brake wheel should have different temperature at brake wheel periphery, and simultaneously in whole braking procedure, the temperature of brake wheel is also stepping, and braking time is longer, and braking force is larger, and break drum temperature is higher.Therefore thermoresponsive switch 5,8,11 should have different operating temperatures, so this also can ensure that in break drum temperature elevation process, electromagnetic valve 3,6,9 acts on successively, shower nozzle 4,7,10 is sprayed water successively.
Each thermoresponsive switch 5,8,11 in native system is installed near brake drum surface position, automobile brake drum surface temperature can be monitored, and can according to the break-make of set temperature threshold duty control solenoid valve circuit, if temperature exceedes the threshold value of setting, circuit turn-on, electromagnetic valve can be opened shower nozzle and spray water to brake wheel.
Specific works process of the present utility model is as follows:
When vehicle starts to brake, break drum temperature is low, and do not reach the operating temperature of 3 thermoresponsive switchs, shower nozzle is not all sprayed water.Along with break drum temperature raises, thermoresponsive switch 5 Controlling solenoid valve 3 is opened, and shower nozzle 4 starts water spray and cools brake wheel.If rate of braking is high and the time is longer, then break drum temperature can continue to raise, and now thermoresponsive switch 8 Controlling solenoid valve 6 is opened, and shower nozzle 7 starts water spray and cools brake wheel.If brake temperature continues to raise, thermoresponsive switch 11 Controlling solenoid valve 9 is opened, and shower nozzle 10 starts water spray and cools brake wheel.When braking stops, thermoresponsive switch resets, closed electromagnetic valve.
