Abstract
The invention relates to an energy-saving vehicle gear oil composition, which comprises the following components: (A) antiwear composite ashless dispersant: 0.5 to 5 weight portions; (B) a composite energy-saving additive: 1 to 5 parts by weight; (C) a vehicle gear oil complexing agent: 1 to 10 parts by weight; (D) a viscosity index improver: 1 to 15 parts by weight; (E) pour point depressant: 0.1 to 2 parts by weight; (F) base oil: 75-95 parts by weight. The vehicle gear oil composition provided by the invention has the advantages of low friction coefficient, excellent extreme pressure wear resistance, thermal oxidation stability and better energy-saving effect, and compared with common vehicle gear oil, the vehicle gear oil composition has the advantages of obviously prolonged service life, obviously improved transmission efficiency and realization of energy-saving and environment-friendly purposes. The invention also relates to a preparation method of the energy-saving vehicle gear oil composition.
Description
Technical Field
The invention belongs to the technical field of lubricating oil and lubricating oil additives, and particularly relates to an energy-saving vehicle gear oil composition.
Background
Under the large trend of energy conservation and emission reduction, the automobile industry focuses on research on an engine assembly, but with continuous excavation of energy conservation potential of the engine, the difficulty and cost of continuous lifting are increasingly increased. Therefore, the research on the fuel-saving performance of the transmission system improves the schedule and becomes an important ring of the whole vehicle development link.
At present, gear oil adopted by a main stream vehicle transmission system in the market still emphasizes performance requirements, and great attention is not paid to energy conservation. Along with the continuous improvement of requirements on energy conservation, environmental protection, fuel economy and the like, higher requirements are put forward on the driving axle oil products. By reducing friction loss of gear shifting gears and bearing gear transmission, the transmission efficiency of a gear system can be improved. The energy saving effect of vehicle gear oils is often very relevant to the design of the formulation system, in particular the choice of additives.
Disclosure of Invention
Based on the foregoing, an object of the present invention is to provide an energy-saving vehicle gear oil composition. Compared with the common GL-5 heavy-load vehicle gear oil, the energy-saving vehicle gear oil composition provided by the invention has better extreme pressure abrasion resistance, thermal oxidation stability and energy-saving performance, and compared with a common product, the life is obviously prolonged, and the transmission efficiency is obviously improved.
To this end, the invention provides an energy efficient vehicle gear oil composition comprising the following components:
(A) Antiwear composite ashless dispersant: 0.5 to 5 weight portions;
(B) Composite energy-saving additive: 1 to 5 parts by weight;
