Abstract
A composite additive for lubricating oil of gears used in the gear-shifting box and rear drive bridge of truck or bus contains mineral oil (at least 20 wt.%), at least one S-containing extreme-pressure antiwearing agent, at least one P-containing extreme-pressure antiwearing agent, at least one oily agent, at least one cleaning disperser, and at least one metal passivating agent and/or antioxidizing agent. Said composite additive can be added to medium-or high-viscosity basic oil, or synthetic basic oil, or their mixture.
Description
The present invention relates to a kind of additive composition for gear lubricating oil, especially a kind of additive composition for gear lubricating oil that is used for load-carrying vehicle and motorbus manual transmission and rear driving axle belongs to the lubricant technical field.
Occurring load-carrying vehicle manual transmission dedicated gear fuel oil meter lattice abroad is in recent years.Before this, the lubricated general of load-carrying vehicle manual transmission gear replaces with API GL-4 or GL-5 class rear driving axle gear grease.Power along with the manual transmission transmission constantly increased afterwards, and designed reduced volume gradually, and the working temperature of lubricating oil raises.Do not have the API GL-4 gear oil of thermal oxidation stability requirement in use to generate more oxidation products, as paint film, sludge deposition influences works better on the parts of manual transmission.Simultaneously, manual transmission extensively adopts synchronizer, and its copper alloy parts have proposed harsher restriction to the corrodibility of gear oil.Recommend API MT-1 (or PG-1) manual gear box oil specification not only to increase the requirement of CRC L-60 thermal oxidation stability as the U.S., and copper corrosion (ASTMD130) is reduced to maximum value 2A level from the maximum value 3B level of former API GL-4 and GL-5 gear oil.Obviously, present API GL-4 and GL-5 gear oil are difficult to satisfy the requirement of modern manual transmission to lubricating oil.
China's load-carrying vehicle and motorbus almost all are to adopt manual transmission.Up to the present, all use general rear driving axle gear oil API GL-3 and GL-4 (also claiming light, middle load gear oil) to substitute lubricating oil, and do not have the manual transmission special oil.
Therefore, the objective of the invention is: the compositions of additives of a kind of load-carrying vehicle and motorbus manual transmission lubricating oil is provided, can adapts to various base oils, and satisfy the requirement of modulation 85W/90 or 80W/90 manual transmission lubricating oil.Also to satisfy the super API GL-4 rear driving axle gear oil requirement of Dong Feng Auto Corporation simultaneously.
