Description
Technical field
The present invention relates to petrochemical industry, more particularly to a kind of enhanced heavy duty automobile gear oil.
Background technology
The credit rating of heavy duty automobile gear oil uses the classifying rules of American Petroleum Institute (API) API, is GL-5 grades, should
Oil product under grade is commonly utilized in rear axle gear, differential mechanism and the manual transmission of heavy load diesel vehicle at home.This
The gear oil most common drain period under individual grade is ten thousand kilometers of 5-6.With the continuous extension of engine oil drain period, visitor
Family it is also proposed requirement to the drain period of gear oil, it would be desirable to be promoted to more than 100,000 kilometers, and this is just to heavy duty automobile tooth
The permanent seal cooling for taking turns oil proposes new requirement, and various aspects of performance is both needed to lifting, could meet extension more than 2 times of effect of drain period
Really.
It is no synchronizer in old-fashioned manual transmission, therefore original GL-5 grade gear oils apply to not tape synchronizer
Manual transmission, if there is synchronizer, its is wear-resistant to require it is different, if still can go out using if GL-5 grade oil products
Existing gearbox abnormal sound and the situation of skidding of putting into gear.But manual transmission new-type in recent years carries synchronizer, and material is brass
It is in the majority with carbon-based.Understanding from the market finds that the manual transmission major part of present heavy load Diesel engine is loaded
Synchronizer, therefore gear oil need to possess the adaptability of synchronizer.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the invention, without answering
In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of enhanced heavy duty automobile gear oil, so as to overcome GL-5 grade vehicle teeth
Take turns thermo oxidative stability, extreme pressure anti-wear, the seal compatibility performance deficiency of oil, it is impossible to meet more than 100,000 kilometers and change oil week
Phase；It does not have synchronizer adaptability, it is impossible to the shortcoming in the manual transmission of tape synchronizer.
To achieve the above object, the invention provides a kind of enhanced heavy duty automobile gear oil, percentage

Following components：150BS base oils：38.1%th, 500N base oils：56%th, compound additive：5%th, pour-point depressant：0.9%.
Preferably, in above-mentioned technical proposal, the 150BS base oils are the class cycloalkyl bright stocks of API I.
Preferably, in above-mentioned technical proposal, the 500N base oils are the class hydrofinishing naphthenic base oils of API II,
Preferably, in above-mentioned technical proposal, the compound additive is added using the gear oil of Lu Borun additives company
Agent GO3230.
Preferably, in above-mentioned technical proposal, the pour-point depressant is polymethacrylates solution.
Preferably, in above-mentioned technical proposal, the concentration of the polymethacrylates solution is 30~50%.
Compared with prior art, the present invention has the advantages that：
The enhanced heavy duty automobile gear oil of the present invention, its formula is reasonable.Performance is better than API GL-5 grades, improves oil product
Thermo oxidative stability, thermal oxide experiment in perform better than, greasy filth is less；The extreme pressure and antiwear behavior of oil product is improved, can be reduced
Abrasion, extends the drain period；The seal compatibility of oil product is improved, leakage is reduced, extends the replacement cycle；Increase synchronizer to adapt to
Property, the manual transmission with tape synchronizer can be applied；Product is reached more than 100,000 kilometers drain periods, and can apply simultaneously
In the manual transmission of back axle and tape synchronizer.
