Abstract

The invention discloses manual transmission lubricating oil for automobiles. The lubricating oil comprises the following components in parts by weight: 75-85 parts of composite base oil, 6-15 parts of polymethacrylate, 0.1-2 parts of di-n-butyl phosphite, 3-5 parts of polyisobutylene succinimide, 2-3.5 parts of a phosphate amine salt, 0.01-0.2 part of isobutenyl sulfide, 0.01-1 part of an antioxidant, 0.1-0.8 part of a mixture of sodium sulfite and sodium dodecyl benzene carbonate, 0.01-0.5 part of a mixture of benzotriazole derivatives and thiadiazole derivatives and 0.001-0.05 part of dimethyl siloxane and fluorosiloxane, wherein the composite base oil is formed by compounding poly alpha-olefin and ester synthesized base oil in a proportion of 10:(1-1.5). The manual transmission lubricating oil for automobiles provided by the invention has excellent durability, frictional characteristic, wear resistance, anti-rust and anti-corrosion properties, an anti-micropitting property, shearing stability and thermal oxidation stability.

Description

Technical field [0001] Ben Youming relates to the field of lubricating oil, in particular to lubricating oil for manual gearboxes for automobiles. Background technique [0002] When the gearbox is working, many transmission components are relatively moving at a high speed under a small gap, such as between meshing gears, between shafts and bearings. Although the working surfaces of these parts have been finely machined, they are bumpy when zoomed in. If these surfaces are not lubricated, strong friction will occur between them. The dry friction between the metal surfaces not only increases the power consumption of the gearbox and accelerates the wear of the working surface of the parts, but also may burn the working surface of the parts due to the heat generated by the friction, causing the gearbox to fail to operate. [0003] The manual gearbox has high transmission efficiency but poor operability, while the automatic gearbox is easy to operate, but the transmission efficiency i...
