Abstract
Lubricant compositions comprises a lubricant base oil blended with a boron-containing ashless dispersant (A) in an amount of 0.035 or more percent of boron by mass, and an alkaline earth metal sulfonate having a total base number of 50 to 500 mgKOH/g (B) in an amount of 0.01 or more percent of alkaline earth metal by mass, all the percentages being based on the total mass of the composition and if necessary a phosphorus additive. The lubricant compositions are superior in effect to enhance the dynamic- and static-friction coefficients in a wet clutch.
Description
The present invention relates to lubricant compositions, more particularly, the present invention relates to be used for the lubricant compositions of automatic driver or continuous variable transmission rig, said composition can improve the frictional behaviour in the warm formula clutch coupling effectively.
Automatic driver is equipped with torque convertr, humid clutch, gear and Bearning mechanism and hydraulic control, to control these parts, determines pinion ratio by the gear teeth number of the gear that is meshing with each other.Automatic driver has the several types gear mechanism, obtains required pinion ratio by selecting the suitable gear according to the speed of a motor vehicle and this definite ratio of loading.Automatic driver has many humid clutches, and some couplings are arranged in the middle of them, and other idle running are so that select to determine the gear of transmission rig gear ratio.When changing the transmission rig gear ratio, the clutch coupling of coupling is threaded off, and other clutch couplinges become coupling.Therefore, change in order to carry out gear fast, humid clutch needs very high dynamic friction coefficient.In addition, in order to transmit motor torque, the humid clutch of coupling must can not slide before threading off, and needed very high static friction coefficient.The performance of the material of clutch coupling and used lubricant has a strong impact on these frictional coefficient.
In design during automatic driver, by determining the hydraulic pressure of size, quantity and the pressurization of humid clutch with the output of its bonded engine.Under the low situation of frictional coefficient in humid clutch, need to increase the hydraulic pressure of their size, quantity and pressurization.The size of humid clutch and the increase of quantity can cause will use the large size automatic driver, and the increase of pressurized hydraulic can make that the load of employed hydro-pump is excessive in the automatic driver.
On the other hand, do not resemble in automatic driver, in the transmission rig of continuous variable, humid clutch is not to be used for gear to change, but as forward and shifter backward.
About improving the problem of the frictional coefficient in the humid clutch, the open 6-240275 of Japanese Patent proposes, and comprises that the lubricant compositions of the succinimide of high alkalinity phenol calcium, succinoamino ashless dispersant, boronation is effective for improving static friction coefficient.The open 8-127789 of Japanese Patent proposes, and the lubricant compositions that contains dimorphism and monotype alkylidene group succinimide and low and high-molecular weight polydimethylsiloxane product can effectively improve dynamically and static friction coefficient.The a lot of lubricant compositions in conjunction with producing with these technology come into operation, but are unsatisfied improving aspect the fuel efficiency, therefore require further improvement.
