Abstract

The invention discloses an energy-saving transmission oil special for a small vehicle. The energy-saving transmission oil is characterized by being prepared from the following raw materials in part by weight: 82 to 95 parts of base oil, 5 to 15 parts of polyisobutene, 0.4 to 2 parts of thiophosphoric acid diester amine salt, 0.4 to 2 parts of sulfurized isobutylene, and 0 to 0.3 part of polymethylmethacrylate, wherein the base oil is type III base oil of which the saturated hydrocarbon content is more than 90 percent, the viscosity index is more than 120 and the sulfur content is less than 0.3 percent. The transmission oil has the advantages that the transmission oil has high extreme-pressure wear resistance and low corrosion on copper, has high low-temperature fluidity to withstand the low temperature of -35DEG C, has high high-temperuatre antioxidant activity and adhesive power and provides good oil film protection for gear surfaces. The transmission oil has low apparent viscosity, the small vehicle employing the transmission oil is smooth in gear shifting and quick in response and can improve the fuel economy, and the energy-saving transmission oil special for the small vehicle is economical, practical, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of automobile gearbox oil, and in particular relates to a special energy-saving gearbox oil for small cars. Background technique [0002] The American Petroleum Institute (API) has proposed two manual transmission oil classification specifications for performance, one is PG-1, which is suitable for manual transmissions with heavy loads and high temperatures up to 150°C, such as trucks and buses; the other is PG-2 is suitable for heavy-duty shaft gear transmission with high offset, such as the last stage transmission of heavy trucks. Since the working conditions of the above two vehicles are very different from those of small-displacement vehicles below 2.0L used as transportation tools in the city, the transmission oils of these two specifications will be difficult and slow to shift gears when used in small vehicles. , high power transmission consumption and other disadvantages. How to provide a kind of en...
