Definitions
- the present invention relates to a lubricating oil composition, and more particularly to a general lubricating oil composition for a vehicle transmission system, which belongs to the technical field of lubricating oils and lubricating oil additives.
- the vehicle transmission system mainly includes the manual transmission system and the drive system.
- the manual transmission system and the drive system require special lubricating oil for lubrication.
- the manual transmission is lubricated with MTF, and the drive system adopts API GL-5 or API GL- 4 vehicle gear oil to lubricate.
- Passenger car manual transmission oil has its own standards for all major automobile manufacturers. It is standardized to pass the SSP-180 synchronizer manual transmission cycle gantry; the highest standard for commercial vehicle manual transmission oil is API MT-1. Through the MACK cycle bench test; the highest standard for drive axle oil is API GL-5, which requires four bench tests of CRC L-42, L-37, L-60, and L-33. Manual transmission oils emphasize the thermal oxidation stability, corrosion resistance, friction characteristics and wear resistance of the oil, while the transaxle oil emphasizes extreme pressure wear resistance, load carrying capacity and scratch resistance. Due to the contradiction between extreme pressure and corrosion resistance, extreme pressure and thermal oxidation stability, anti-wear type and friction characteristics, it is difficult to generalize the manual transmission oil and the axle oil.
- MIL-PRF-2105E proposes general specifications for manual transmission oils and transaxle oils, but domestic and foreign literature and patents do not detail and disclose the composition of oils meeting the MIL-PRF-2105E specifications.
- the full transmission system lubricating oil composition provided by the invention can fully meet the US military specifications
- the object of the present invention is to provide a lubricating oil composition for a full transmission system, which has excellent high and low temperature properties, extreme pressure and abrasion resistance, scratch resistance, load bearing capacity, friction characteristics, rust and corrosion resistance, and thermal oxidation stability.
- Performance, anti-wear durability, anti-foaming and sealing adaptability fully meet the requirements of the US military standard MIL-PRF-2105E, can meet the all-weather lubrication of all vehicle transmission systems, and realize the generalization of oil for the whole transmission system.
- the present invention carefully selects each base oil component and additive component in the lubricating oil composition, and performs the interaction relationship between each component oil, each component functional additive, and the base oil and the additive.
- the lubricating oil composition for the whole transmission system formulated by the invention has excellent energy-saving anti-friction performance, high and low temperature performance, extreme pressure anti-wear performance, anti-scratch property, load bearing capacity, friction property, anti-rust and anti-corrosion performance, thermal oxidation stability Performance, anti-wear durability, anti-foaming and sealing adaptability, the product meets SAE75W, 75W/80, 75W/85, 75W/90, 80W, 80W/85, 80W/90, 80W/140 viscosity grade requirements, passed CRC L-42, L-37, L-33, L-60, L-60-1 full-size gear gantry, truck and bus manual transmission MACK cycle gantry and car manual transmission SSP-180 synchronous and durable
