Problems solved by technology
In addition, due to the widespread use of synchronizers on new manual transmissions and drive axles, the original transmission oil can no longer meet the requirements; APIGL-5 oil that meets the MIL-L-2105D specification is used in actual In the process, a large amount of sludge, paint film and deposits appeared, resulting in the decline of oil performance and seal leakage, which could no longer meet the requirements of the actual use of vehicle gear mechanisms.

The invention discloses vehicle gear oil which comprises the following components in percentage by mass: 85%-95% of base oil and 15%-10% of other addition agents. Synthetic oil compounded by polyinternalolefins and oil soluble polyether acts as the base oil of the vehicle gear oil. The vehicle gear oil provided by the invention has the obvious advantages that the vehicle gear oil has good comprehensive performance, and each performance index achieves the use requirement; the vehicle gear oil has favorable viscosity-temperature characteristic, thermal oxidation stability, extreme pressure property, abrasion resistance, load bearing resistance, demulsibility, spumescence resistance, corrosion resistance, anti-rust property, storage stability, synchronous durability and seal material compatibility, guarantees that a vehicle gear mechanism has sufficient oil membrane thickness under severe conditions, lowers the friction coefficients among gear surfaces, improves the drive efficiency of a gear mechanism, and prolongs the service life and the oil draining period of a vehicle gear drive system effectively.
Description
technical field [0001] The invention relates to a vehicle lubricating oil, especially a vehicle gear oil. Background technique [0002] Vehicle gear oil is a general term for lubricants used in vehicle gear transmission systems. It is mainly used to lubricate manual transmissions, steering gears, and transmission gears of front and rear axles in vehicles such as automobiles, tractors, and construction machinery. The main function of vehicle gear oil in the gear transmission mechanism is to reduce friction, reduce wear, and cool parts; at the same time, it also plays the role of easing vibration, reducing impact, preventing rust and cleaning dirt on the friction surface. [0003] With the development of my country's automobile industry, the performance structure of vehicle equipment has undergone great changes: First, due to the requirements of vehicle users for fuel economy, vehicle manufacturers have increased the transmission power density of the rear axle and gearbox, so ...
