Description
The present invention relates to a kind of universal oil composition for manual speed variator, belonging to the mixture of multiple compound and do the lubricating oil composition that additive is a feature, is a kind of gear lubricating oil composition that is used for the manual transmission and the rear bridge driven of load-carrying lorry and motorbus.
Chinese patent CN 1203264A discloses a kind of gear lubricating oil composition, is a kind of gear lubricating oil composition that is used for load-carrying lorry and motorbus manual transmission and rear driving axle.It contains (A) a large amount of mineral oil; (B) at least a sulfur-bearing extreme pressure, anti-wear agent; (C) at least a phosphorous extreme pressure, anti-wear agent; (D) at least a oiliness improver; (E) at least a detergent-dispersant additive; (F) at least a metal passivator and/or oxidation inhibitor, (G) at least a pour point depressant; (H) at least a kilfoam.Its quality meets automotive gear oil (super APIGL-4) specification of loading in API MT-I (or PG-I) manual gear box oil specification and the China.But because the low-temperature performance of said composition oil product is relatively poor, pour point has only-18 ℃, can't guarantee the normal lubricated of gear in the winter in Han Qu and severe cold district, causes the vehicle difficulty that can't normally start and shift gears, therefore, and can't be in Han Qu and the use of severe cold district.Simultaneously, this formula system resistance of oxidation is poor, to certain influence is arranged the work-ing life of adopting the oily oil product of debugging of (grand celebration) paraffin base mineral oil and hydroisomerizing.Its reason is: the paraffin base mineral oil sulphur content is low, the nitrogen content height, and the antioxidant property of oil product self is relatively poor, causes the oil draining period of oil product to shorten; Though and hydroisomerizing oil has good oxidation inhibitor susceptibility, the anti-oxidant of oil product lacks of staying power, and also can shorten the work-ing life of oil product.And the manual gear box oil product of having developed at present that Han Qu uses that are suitable for all adopt the polyalphaolefin synthetic oil to be base oil basically, owing to synthetic oil costs an arm and a leg, therefore, cause composition oil product cost too high, be subjected to the restriction of raw material simultaneously, output is subjected to certain restriction, so be difficult to widespread use.
It is extensive to the purpose of this invention is to provide a kind of scope of application, long service life, and the cheap relatively universal oil composition for manual speed variator of cost.
The objective of the invention is to realize by following technical solution.
