Description

Technical Field

[0001] The invention relates to the technical field of manual transmission oil additives, in particular to a manual transmission oil composite additive. Background Art

[0002] Transmission oil is an oil product that keeps the gear system clean. It can ensure the normal operation of the gearbox and extend the life of the transmission device. Transmission oil can basically be used in automatic transmissions on the market. In fact, the design of each automatic transmission has different technical requirements. Even if the same type of transmission is configured in different models, its torque, weight, speed, structure, etc. will be different. Therefore, the original factory has its own designated special transmission oil. Different transmission oils are one of the reasons that affect the quality of gear shifting. The most fundamental difference is the difference in its friction system. HFM-ATF has more delicate oil molecules and efficient anti-shear ability. In the state of semi-clutch or at the moment of engagement, the oil film acting on the surface of the friction material can play a very effective suspension state and slip, which can buffer the strong impact of the moment, making the engagement smoother and the shifting smoother. At the same time, the delicate oil molecules greatly reduce the valve jam phenomenon and make the valve body work more smoothly. Transmission oil is an oil product that keeps the gear system clean. It plays a role in lubrication and extending the life of the transmission device. It has low temperature resistance and can also perform extremely effective lubrication at low temperatures, reducing oil loss under harsh operating conditions. Depending on the gearbox structure, gearbox oil is divided into automatic gearbox oil and manual gearbox oil.

[0003] At present, vehicles are the most basic means of transportation in human society, and manual transmissions are one of the most important key devices in vehicle transmission systems. With the continuous development of vehicle technology and transmission technology, higher requirements are placed on the lubrication performance of transmission oil. Vehicle manual transmissions have developed from fewer gears to more gears, from clutches to clutchless gears, and from manual gears to automatic gears. Each step of development has placed higher requirements on the performance of lubricants.

[0004] At present, the main oil used for manual transmission in my country is GL-4 medium-load vehicle gear oil, and the application of special oil products for manual transmission is scarce. In particular, with the increasing popularity of manual transmission synchronizer equipment, GL-4 oil products have many problems in use, such as poor corrosion resistance, short oil change cycle, inability to lubricate synchronizer equipment well, and more sludge. In view of this, a manual transmission oil composite additive invention is proposed, and the invention can be used to adjust related manual transmission oil products. Summary of the invention
