Abstract

The invention relates to the field of lubricating oil and especially relates to lubricating oil specially used for a hybrid electric vehicle transmission. The lubricating oil includes, by mass, 87.7-89.7 parts of base oil Yubase 4, 0.5 parts of an additive LK1-300, 1.0-3.0 parts of an additive LK12-095 and 8.8 parts of an additive LK4165B, wherein the total mass part of the base oil Yubase 4, theadditive LK1-300, the additive LK12-095 and the additive LK4165B is 100 parts. The lubricating oil has high insulation performance, excellent abrasion protective capability and excellent temperature increase character. The lubricating oil also can supply a proper friction coefficient to clutches.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special lubricating oil for a gearbox of a hybrid electric vehicle. Background technique [0002] The main structure of a hybrid vehicle gearbox is a motor, a brake clutch, and a compound planetary gear mechanism. The motor and the entire mechanical system share a set of lubrication system, which puts forward requirements on the insulation performance of the oil; in order to avoid slipping of the brake clutch, the oil is required to provide a suitable friction coefficient between the clutches; the compound planetary gear mechanism has high The advantages of high transmission efficiency and torque output require the oil to have good wear protection capabilities; at the same time, in order to avoid excessive oil temperature during use, the oil is required to have good temperature rise characteristics. Existing gearbox lubricating oils are difficult to meet the above requirements s...
