Method.
Background technology
Vehicle drive system lubricating oil mainly includes gear box oil, drive axle oil etc..With the quick hair of speed change box technology
Exhibition, gearbox oil product progressive updating are regenerated, and the gear box oil different from APIGL-4 and APIGL-5 standards occur, are such as become manually
Fast case oily (MTF), hydraulic automatic gear box oil (ATF), stepless automatic transmission case oily (CVTF), double clutch special oil (DCTF)
Deng wherein manual gear box oil is most widely used.
With the continuous progress of requirement more and more higher of the people to car steering performance and vehicle speed variation box technology, user couple
Gearbox gear oiliness can propose requirements at the higher level.Gear box oil is in addition to it can ensure gearbox normal work, vehicle gear box
Oil should possess excellent anti-corrosive properties, thermo oxidative stability, seal compatibility and good oxidation stability, while should also have
Excellent wear-resistant and bearing capacity, excellent low temperature performance and fuel economy.The frictional behavior of oil product is poor, then can not
Suitable coefficient of friction and moment of friction are provided, synchronizer service life and shifting comfort will be influenceed.Manual gear box oil exists
On the basis of APIGL-4, also need possess high corrosion resistance, the synchronous life-span of length, excellent thermal oxidation stability and sealing
The performance such as adaptability and low glutinousization.Because the car mass of different manufacturers production is different, in addition with urban transportation condition
Deterioration, automobile needs frequent starting and gear shift；The automobile travelled more for mountain road, because road conditions are severe, automobile also needs
Buty shifting, therefore automobile requires more and more higher to gearbox with oil.
Stepless automatic transmission case oil (CVTF) is the special transmission fluid of ST (CVT), belongs to CVT key
Functional part.After early development goes out CVT, due to lacking suitable traction without obtaining practical application.In recent years, it is domestic
Outer enterprise all endeavours the development of CVT passenger cars.CVTF will have a very big development space in the technical market of China.CVTF
Not only there is good lubrication property, and to possess appropriate external friction and internal friction (i.e. suitable friction factor), with
Reach the purpose of power transmission.CVTF performance directly affects power transmission efficiency, and Novel CVT F has turned into improves CVT transmission effects
Rate and the important means in life-span.
