Abstract
A processing method of hydraulic transmission oil of a vehicle automatic transmission is characterized in that the hydraulic transmission oil is prepared from 3-8wt% of tricresyl phosphate, 8-12wt% of polymethacrylate, 5-10wt% of N-phenyl-alpha-naphthylamine, 0.3-0.8% of 2,6-di-tert-butyl-4-methylphenol, 8-12wt% of sorbitol monooleate, 2-5wt% of methyl silicone oil and 60-68wt% of base oil 60N. The processing method comprises the following steps: heating the base oil 60N to 75-85DEG C, sequentially adding the polymethacrylate, the tricresyl phosphate, the sorbitol monooleate and the N-phenyl-alpha-naphthylamine, and stirring; and cooling to 55-65DEG C, adding the methyl silicone oil, stirring, and adding the 2,6-di-tert-butyl-4-methylphenol. According to the invention, various hydraulic transmission oil functions and performances required by the vehicle automatic transmission are completely satisfied, so the service life of equipment is substantially prolonged.
Description
Technical field:
The present invention relates to a kind of working method of vehicle automatic speed variator hydraulic transmission oil.
Technical background:
In recent years, along with the develop rapidly of automobile industry, the automatic transmission in the vehicle is also in continuous update.Automatic transmission is one of important spare part in the vehicle; The hydraulic transmission oil of use in vehicle automatic speed variator is a kind of lubricating oil of multifunctional and multipurpose; It is used for automatic driver and realizes lubricated, cooling, transmission of power, temperature control and level and smooth automatic clutch speed change and improve vehicle engine power, improve the transmission performance of vehicle that the driving medium that in fluid torque-converter and fluid-flywheel clutch, uses is claimed hydraulic transmission oil.Hydraulic transmission oil is claimed power transmission fluids or power shift transmission fluid again.
The development of hydraulic transmission oil, production and application have been installed automatic transmission and have been developed along with automobile.Automatic transmission can make the variation of automobile adaptation running resistance, improves the dynamic performance of automobile, and the starting vibrations are little, and ride comfort can also shield during overload, and can eliminate exhaust pollution.Fluid torque-converter, gear mechanism, humid clutch and worm gearing etc. are housed in automatic transmission and torque converter, and these mechanisms all use with a kind of oil lubrication and transmission energy.So hydraulic transmission oil must have multiple function and performance, in torque converter, it is as the driving medium of hydrodynamic force ability.In hydraulic gear, it is as the transmission medium of static energy.In clutch coupling, it is as the transmission medium of sliding friction ability.On wearing piece surface, hydrodynamic drive liquid also the words of the lowly carry little weight heat transmission medium, control pair of friction components surface temperature prevents sintering.In gear mechanism, wheel and thrust bearing, it is as lubricant medium.Present hydraulic transmission oil viscosity index is low, high-temperature oxidation resistance is poor, causes defectives such as easy carbon deposit, clutch coupling easy burn-out.Traditional hydraulic transmission oil can not satisfy the demand of fast-developing transmission for vehicles, becomes the bottleneck that the restriction vehicle technology updates.Therefore, developing a kind of hydraulic transmission oil new and effective, the multifunctional and multipurpose vehicle automatic speed variator is very important.
Summary of the invention:
The object of the invention is exactly the processing that a kind of vehicle automatic speed variator hydraulic transmission oil will be provided
Method, it can overcome, and traditional hydraulic transmission oil viscosity index is low, the defective of high temperature antioxygen property difference.The objective of the invention is to realize like this; The working method of vehicle automatic speed variator hydraulic transmission oil; It is characterized in that: each starting material is tricresol phosphate fat 3%-8%, Rohm tech inc 8%-12%, N-PA 5%-10%, DBPC 2,6 ditertiary butyl p cresol 0.3%-0.8%, Sorbitol Powder list olein 8%-12%, methyl-silicone oil 2%-5%, base oil 60N 60%-68% by weight percentage; At first base oil 60N is heated; Temperature is controlled at 75 ℃-85 ℃, under the state that stirs, adds Rohm tech inc, tricresol phosphate fat, Sorbitol Powder list olein, N-PA in order successively, to be mixed evenly after; Temperature is cooled to 55 ℃-65 ℃; After the adding methyl-silicone oil stirred half a hour, the adding DBPC 2,6 ditertiary butyl p cresol stirred and gets final product.The present invention satisfies vehicle variators such as two clutch gearboxes, automatic mechanical transmission fully must have multiple function and performance demands to hydraulic transmission oil; Solved that existing variator fluid power gear compound viscosity index is low, the problem of high temperature antioxygen property difference, prolonged the work-ing life of equipment greatly.
Embodiment:
The working method of vehicle automatic speed variator hydraulic transmission oil; It is characterized in that: each starting material is tricresol phosphate fat 3%-8%, Rohm tech inc 8%-12%, N-PA 5%-10%, DBPC 2,6 ditertiary butyl p cresol 0.3%-0.8%, Sorbitol Powder list olein 8%-12%, methyl-silicone oil 2%-5%, base oil 60N 60%-68% by weight percentage; At first base oil 60N is heated; Temperature is controlled at 75 ℃-85 ℃, under the state that stirs, adds Rohm tech inc, tricresol phosphate fat, Sorbitol Powder list olein, N-PA in order successively, to be mixed evenly after; Temperature is cooled to 55 ℃-65 ℃; After the adding methyl-silicone oil stirred half a hour, the adding DBPC 2,6 ditertiary butyl p cresol stirred and gets final product.Hydraulic transmission oil of the present invention is through detecting, and viscosity index is 215, and oxidation stability (acid number reaches the time of 2.0mgKOH/g) was greater than 1000 hours.The similar products at home and abroad viscosity index is 150, oxidation stability (acid number reaches the time of 2.0mgKOH/g) 500 hours.
