Problems solved by technology

However, after the new automatic transmission transmission fluid is added, it will be immediately polluted by the old transmission fluid in the system, and the undischarged deposits will seriously affect the working performance of the system
[0004] Carbon deposits and colloids in the valve body and oil circuit of the automatic transmission will cause crashes, delay in shifting, or sticking of precision parts such as solenoid valves, poor operating smoothness, and increased wear of components such as couplers
The cost of replacing the automatic transmission is as high as 10,000 to 20,000 yuan
[0005] At present, there are many kinds of protective agents for automatic transmissions on the market, and the quality is uneven, which cannot protect automatic transmissions effectively. The main reasons are: (1) The product has a single function and cannot fully protect automatic transmissions. ; (2) The selection and proportion of additives are unreasonable; (3) Due to price competition and other reasons, there are many inferior products on the market

Abstract

The present invention relates to a self-changing gearbox protective agent and a preparation method thereof. The protective agent comprises the following components by weight: 15-25 parts of cetyl nano calcium borate, 15-25 parts of base oil 250N, 40-60 parts of base oil 60N, 2-6 parts of high basic value synthetic calcium sulfonate T106, 2-8 parts of bisoctyl zinc dithiophosphate T203, 0.1-0.6 part of poly-alpha-olefin, 2-10 parts of a viscosity index improver and 0.001-0.010 part of a lubricant anti-foaming agent. The protective agent provided by the present invention has the advantages of reasonable formula, complete effects, product safety and stability and compatibility with various types of ATF, can effectively maintain the smooth passage of the self-changing gearbox, avoid shifting hysteresis, improve shifting smoothness, extend the service life of the self-changing gearbox and reduce maintenance costs.

Description

technical field [0001] The invention relates to the technical field of automobile automatic transmission maintenance, in particular to an automatic transmission protective agent and a preparation method thereof. Background technique [0002] Modern automotive automatic transmissions are highly sophisticated power transmission devices, mostly controlled by computers, equipped with many precision components, such as: hydraulic torque converters, planetary gears, hydraulic control systems and complex and small oil passages, etc., which are harmful to pollution Very sensitive to substances and temperature changes. If the necessary maintenance is lacking, the automatic transmission will have malfunctions such as rough work and difficulty in shifting gears. According to statistics, 90% of automatic transmission failures are caused by overheating or transmission fluid contamination and deterioration. [0003] Conventional automatic transmission maintenance can only replace 40% of...
