Wet clutch has two duties, i.e. clutch engaged state and released state, it is contemplated that the operating characteristic of automobile air compressor, selects air pressure normally closed wet type multi-clutch in the technical program, and structure is as it is shown in figure 1, its operation principle is:
Engagement (normality)
Under normal conditions, rotating plate 17 and driven disc 18 are mutually adjacent under the effect of diaphragm spring 14, make to form frictional connection between power input tooth post 2 and clutch plate 3, be connected by spline between clutch plate 3 and the second step face 102 of bent axle 1 and output power on air compressor crank.
Released state
The compressed air being passed through in air chamber 19 promotes piston 8, piston 8 promotes push-plate 11 to be moved to the left, and push-plate 11 overcomes the elastic force of diaphragm spring 14 to make it be moved to the left, and continuous you make external tooth housing 12 be moved to the left, at this moment rotating plate 17 and driven disc 18 are separated from each other and lose frictional force, clutch separation.
Clutch Control mode is: air-compressor clutch is controlled by the gas pressure change valve being arranged on gas bomb, setting higher limit and lower limit according to vehicle operation air pressure, such as, the upper limit is set as 8 kilograms, lower limit is 6 kilograms, when air pressure reaches 8 kilograms, gas pressure change valve is connected, and controls clutch engagement, the cylinder separated is brought about the desired sensation, making clutch separation, thus cut off the power input of air compressor, air compressor machine quits work.When air pressure is less than 6 kilograms, gas pressure change valve disconnects, and the cylinder controlling clutch resets under the effect of diaphragm spring, simultaneously clutch engagement, and air compressor machine is started working.
The high workload air pressure of this utility model clutch is 10bar, and maximum speed is 4200rpm, works for wet type, nominal torque 400NM, the most lower can engage and separate.
If the wet clutch mentioned in this programme is promoted, by the installation amount of annual 2000000,10 hours/day are made in each turner, the air compressor machine power of each car is 5KW, the cycle of operation of air compressor machine is work in 10 minutes, and work in 10 minutes stops, and can save 25KW each every day.2000000 every days save 50,000,000 kilowatts, and 5 kilowatts of fuel oil consumption hourly are about 0.25 kilogram, 2,000,000 every day saving fuel oil 0.28*10000000=2500000 kilogram, 2.63 kilograms of CO2/ liters of the carbon strength factor of diesel oil, diesel oil every liter 0.738 kilogram,
25000000/1.738=33875338.75/ rise
33875338.75*2.63=89092140.91/ kilogram
Therefore, reduce CO2 emission 89092140.91 kilograms, and eliminate the exhaust noise of vehicle, it addition, because the working time of air compressor decreases, improve its life-span, decrease fault rate, thus directly enhance traffic safety.
The foregoing is only preferred embodiment of the present utility model; not in order to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment, the equivalent made, be all contained in protection domain of the present utility model within.
