Description

Automatic gearbox oil
Technical Field
The invention relates to automatic transmission oil.
Background
An automatic transmission is a transmission device that can automatically perform an automatic shift operation in accordance with a vehicle speed and an engine speed, which occurs in contrast to a manual transmission. AT present, four types of automatic transmissions for automobiles are common, namely a hydraulic Automatic Transmission (AT), a mechanical stepless automatic transmission (CVT), an electric control mechanical automatic transmission (AMT) and a double-clutch automatic transmission.
Automatic Transmission oil is called Automatic Transmission Fluid (Automatic Transmission Fluid) for short, and is oil liquid specially used for an Automatic Transmission. Early automatic transmissions did not have dedicated oil, but instead were replaced with engine oil. Because of the wide variation in operating conditions and specifications, engine oils are rapidly being eliminated as an automatic transmission fluid. The special oil liquid for the automatic transmission used at present is not only transmission oil of a hydraulic torque converter, but also lubricating oil of a planetary gear structure and hydraulic oil of a gear shifting device.
The automatic transmission oil in the prior art has the defects of short service life, poor lubricating effect, easiness in foaming, no oxidation resistance, poor antirust performance and the like.
Disclosure of Invention
The invention provides an automatic gearbox oil. The invention adopts the following technical scheme:
the automatic transmission oil is composed of the following raw materials in percentage by mass:
0.1 to 0.9 percent of antiwear agent,
0.3 to 1.4 percent of antioxidant,
0.5 to 1.5 percent of molybdenum dialkyl dithiocarbamate,
the balance being base oil.
Preferably, the antiwear agent is chlorinated paraffin, chlorinated fat, sulfurized olefin, sulfurized animal and vegetable oil, sulfur and phosphorus compound, phosphate or borate. Such as sulfurized isobutylene.
Preferably, the antioxidant is one or a mixture of amine antioxidant and phenolic antioxidant. Preferably, the antioxidant is 4,4' -dioctyldiphenylamine or 2, 4-dimethyl-6-tert-butylphenol.
Preferably, the base oil is a mineral oil, a vegetable oil, or a synthetic oil. Mineral oil, ISOVG viscosity grade no greater than 100, such as mineral oil No. 32; vegetable oils include rapeseed oil, soybean oil, peanut oil or castor oil; the synthetic oil comprises a low viscosity poly alpha-olefin, diester, or polyol ester. The base oil may also be a 70N base oil, a 100N base oil, a 150N base oil, or a polyalphaolefin base oil.
The automatic transmission oil is composed of the following raw materials in percentage by mass:
0.1 to 0.9 percent of antiwear agent,
0.3 to 1.4 percent of antioxidant,
0.5 to 1.5 percent of molybdenum dialkyl dithiocarbamate,
0.2 to 0.6 percent of defoaming agent,
the balance being base oil.
Preferably, the defoamer is a perfluoropolyether oil (PFPE) grease and/or polydimethylsiloxane. More preferably, the defoaming agent is formed by mixing perfluoropolyether oil (PFPE) grease and polydimethylsiloxane according to the mass ratio of (1-3) to (1-3).
The automatic transmission oil can be simply prepared by adopting a conventional method, for example: weighing the raw materials, mixing, stirring at the temperature of 60-90 ℃ for 2-4 hours, and naturally cooling to obtain the automatic transmission oil.
The automatic transmission oil disclosed by the invention is reasonable in proportion, has a good lubricating effect in a low-temperature state, and also has good bubbling resistance and oxidation resistance. The automatic gearbox system applied to the automobile can improve the friction performance of oil products, has better anti-shaking performance, and can improve the discomfort problem experienced by a driver.
The automatic gearbox oil of the invention has the following advantages:
1) good thermal oxidation stability. Like engine oil, the oxidation stability of oil directly determines the service life of automatic transmission oil and the service life of automatic transmission. Because the use temperature of the automatic gearbox oil is very high, if the thermal oxidation stability is not good, oil sludge, varnish, carbon deposit, sediment and the like are formed, so that the slip of a clutch plate and a brake plate is caused, and the faults of failure of a control system and the like occur.
2) Good resistance to foaming. The generation of foam in automatic transmission oil in automatic transmissions is very detrimental to the driveline, as determined by the operating properties of the hydraulic automatic transmission oil. The hydraulic torque converter and the speed changer are supplied with oil by the same oil circuit system. Therefore, the medium is used for transmitting power by the torque converter, and is used for automatically controlling the transmission and lubricating and cooling the transmission. Foam can cause a reduction in torque converter transmission power, and the compressibility of foam causes pressure fluctuations and a reduction in oil pressure in the hydraulic system, which in severe cases can cause an interruption in oil supply. The oil is mixed with a large amount of air, so that the amount of lubricating oil is actually reduced. These bubbles increase temperature during compression, which accelerates oil aging, affects oil life, and causes early wear of parts.
3) Good abrasion resistance. Can ensure that: the transmission of each gear in the planetary gear is needed. ② the requirement of the working efficiency of the clutch plate. And thirdly, the requirement of the service life of the automatic transmission.
4) The matching performance with the rubber sealing material in the system is good.
5) Good friction characteristics. The key of ensuring smooth work of all parts of the transmission gear is to reduce noise and prolong service life.
6) Excellent corrosion and rust resistance. The transmission and the cooler are provided with components such as a copper joint, a brass bush, a brass filter, a thrust washer and the like. The parts contain a large amount of nonferrous metals, and the automatic transmission oil can ensure that copper corrosion and other metal rusting cannot be caused.
7) Excellent in storage stability.

1) good thermal oxidation stability. Like engine oil, the oxidation stability of oil directly determines the service life of automatic transmission oil and the service life of automatic transmission. Because the use temperature of the automatic gearbox oil is very high, if the thermal oxidation stability is not good, oil sludge, varnish, carbon deposit, sediment and the like are formed, so that the slip of a clutch plate and a brake plate is caused, and the faults of failure of a control system and the like occur.
2) Good resistance to foaming. The generation of foam in automatic transmission oil in automatic transmissions is very detrimental to the driveline, as determined by the operating properties of the hydraulic automatic transmission oil. The hydraulic torque converter and the speed changer are supplied with oil by the same oil circuit system. Therefore, the medium is used for transmitting power by the torque converter, and is used for automatically controlling the transmission and lubricating and cooling the transmission. Foam can cause a reduction in torque converter transmission power, and the compressibility of foam causes pressure fluctuations and a reduction in oil pressure in the hydraulic system, which in severe cases can cause an interruption in oil supply. The oil is mixed with a large amount of air, so that the amount of lubricating oil is actually reduced. These bubbles increase temperature during compression, which accelerates oil aging, affects oil life, and causes early wear of parts.
3) Good abrasion resistance. Can ensure that: the transmission of each gear in the planetary gear is needed. ② the requirement of the working efficiency of the clutch plate. And thirdly, the requirement of the service life of the automatic transmission.
4) The matching performance with the rubber sealing material in the system is good.
5) Good friction characteristics. The key of ensuring smooth work of all parts of the transmission gear is to reduce noise and prolong service life.
6) Excellent corrosion and rust resistance. The transmission and the cooler are provided with components such as a copper joint, a brass bush, a brass filter, a thrust washer and the like. The parts contain a large amount of nonferrous metals, and the automatic transmission oil can ensure that copper corrosion and other metal rusting cannot be caused.
7) Excellent in storage stability.
