Abstract
The invention discloses an engineering machinery heavy load automatic transmission fluid which is formed through the following way: poly-alpha olefin is used as base oil, and then the base oil is combined with multiple composite additives including an antioxygen, a friction improver, an antiwear agent, an oiliness agent, an anti-foaming agent, an anti-emulsification agent, an antirust agent and a metal deactivator. The engineering machinery heavy load automatic transmission fluid has excellent high temperature oxidation resistance, excellent adaptation with various friction materials, relatively oxidation resistance, better frictional characteristic, high torque transmission efficiency, excellent abrasion resistance and consistency with a sealing material, better high-and-low temperature performance, and can effectively prolong the service life of a power transmission system.
Description
Technical field
The invention belongs to engineering machinery heavy loading automatic transmission fluid field.
Background technology
Along with the fast development of automatic transmission box technology, high-power Hydrodynamic transmission is widely used in heavy off highway vehicle and heavy engineering mechanical means.According to the feature of heavy off highway vehicle and heavy engineering mechanical means automatic gear-box, each instrument factory commercial city proposes respective technical requirements.Automatic gear-box can meet the requirement that vehicle is frequently started to walk, frequently accelerated, and can accelerate to max. speed continuously, improves vehicle start acceleration characteristics, thus improves car load overall operation speed.Simultaneously due to the effect of torque converter, automatic gear-box can increase moment of torsion in the vehicle start stage, is conducive to making full use of of engine power.Automatic transmission fluid is as the important component part of automatic transmission, along with China's road, bridge construction and the work fast development of various fields, increase the demand of heavy off highway vehicle and other various engineering machinery, engineering machinery heavy loading automatic transmission demand is also in continuous increase.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of have excellent high-temperature oxidation resistance, good with various friction materials adaptability, higher frictional coefficient, preferably rubbing characteristics, high moment of torsion transfer efficiency, good abrasion resistance, good sealing material consistency, preferably high temperature performance, effectively can improve the engineering machinery heavy loading automatic transmission fluid in power drive system work-ing life.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on poly-alpha olefins, coordinate multiple composite additive, its each constituent mass percentage ratio is:
