Abstract

The invention discloses special oil for an automatic gearbox of an AMT (automatic manual transmission), which is prepared from the following materials in parts by weight: 10-90 parts of base oil, 10-90 parts of polymerized alpha olefin, 1-8 parts of polyisobutene, 1-8 parts of ethylene propylene rubber, 0-2 parts of dibutyl phosphate, 0-2 parts of sulfur and phosphorus double-nitrogen derivative,0-2 parts of thio-phosphoric acid compound amine salt, 0.5-2 parts of sulfurized isobutylene and 0.1-0.5 parts of polymethylmethacrylate. The special oil for the automatic gearbox of the AMT disclosed by the invention has the following advantages of excellent extreme-pressure anti-wear property, small corrosion to copper, good low-temperature fluidity, good high-temperature antioxidant property, strong adhesive power and excellent oil film protection to a gear surface, and can resist the low temperature of 45 DEG C below zero. The special oil for the automatic gearbox of the AMT disclosed by the invention has small viscosity, good lubricating property and small flow resistance at the room temperature, and is energy-saving and environment-friendly special oil for the automatic gearbox of the AMT with quick instruction response to an electric actuator and excellent fuel economy.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission oil, and in particular relates to a special oil for AMT automatic transmission. Background technique [0002] AMT automatic transmission is actually a set of electric control actuators added on the basis of manual transmission to complete the actions of gear selection, gear shifting and clutch separation or combination, so it has high transmission efficiency and economy. Compared with the traditional automatic transmission AT, AMT has the advantages of low cost and light weight, and is especially suitable for small cars with small kinetic energy storage and distribution. For commercial vehicles, AMT improves the power and fuel economy of the vehicle, and reduces emission pollution; it can make the driver's operation convenient and reduce labor intensity, and the driver focuses most of his energy on the observation and judgment of road conditions, improving driving safety. AMT is ...
