A lubricating oil composition which comprises (A) a base oil, (B) calcium salicylate having a base number of 50 to 300 mgKOH/g in an amount of 0.005 to 0.07 percent by mass in terms of calcium, (C) an SP type extreme pressure additive in an amount of 0.005 to 0.07 percent by mass in terms of phosphorous, (D) a specific succinimide compound in an amount of 0.1 to 6 percent by mass, and (E) a boron-containing ashless dispersant in an amount of 0.001 to 0.05 percent by mass in terms of boron, based on the total mass of the composition. The lubricating oil composition can prevent pitching of a transmission, resulting in the extended fatigue life thereof, and exhibits excellent and long-lasting anti-shudder properties.
一种润滑油组合物,包括:(A)基础油;(B)水杨酸钙,其碱基数为 50 至 300 mgKOH/g,钙的用量为 0.005 至 0.07%(以质量计);(C)SP 型极压添加剂,其用量为 0.005 至 0.(D) 特定琥珀酰亚胺化合物,质量百分比为 0.1% 至 6%;以及 (E) 含硼无灰分散剂,以组合物总质量为基准,硼的质量百分比为 0.001% 至 0.05%。该润滑油组合物可以防止变速器的跳动,从而延长其疲劳寿命,并表现出卓越而持久的防抖特性。
