Abstract

The invention discloses a lubricating oil composition for an integrated electric drive assembly speed reducer. The lubricating oil composition comprises the following components in percentage by weight: 80%-90% of base oil, 4%-12% of a viscosity index improver, 5.5%-8% of a composite additive, 0.1%-0.5% of a reinforcing agent and 0.3%-0.5% of a pour point depressant. The product provided by the invention has relatively low viscosity, relatively high viscosity index, excellent high-temperature oxidation resistance, extreme-pressure wear resistance, shearing stability, copper corrosion protection and electrochemical characteristics; the lubricating oil provides excellent protection for gears and bearings, has good compatibility with sealing materials and motors, provides excellent protectionand power output efficiency for integrated electric drive assembly reducers, and is especially suitable for lubrication of integrated electric drive transmissions of pure electric buses.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition for an integrated electric drive assembly reducer. Background technique [0002] With the continuous development of new energy vehicle technology, the integrated design of components has become an inevitable trend. Through integrated design, on the one hand, it can simplify the transfer of OEMs and improve the product qualification rate; on the other hand, it can also achieve the purpose of reducing weight and saving costs. [0003] The electric drive mode of electric vehicles can basically be divided into two types: motor central drive and electric wheel drive. Among them, the motor central drive system integrates the motor, constant speed ratio reducer and differential, and two half shafts connect the two driving wheels. Since there is no clutch and transmission, the volume and quality of the mechanical transmission can be reduced. Similar to the ...
