Abstract

A lubricating oil composition prepared by incorporating (A) 0.05 to 5 wt % of an alkenylsuccinic acid ester and/or an alkylsuccinic acid ester and (B) 0.005 to 5 wt % of a fatty acid ester of a polyhydric alcohol in a base oil. This composition has low frictional characteristics, i.e., a small ratio of the static friction coefficient to the dynamic friction coefficient and gives a less shock upon gear changes. In addition, it undergoes less changes in frictional characteristics with the temperature change or with the lapse of time. Therefore, it is well adapted for reduction in the size of, for example, a transmission. Thus, the lubricating oil composition is extremely effective as the lubricating oil for an automatic transmission, a part having a wet clutch or wet brake of, for example, tractors, and the like.

The present invention relates to any lubricating oil composition. Background technology ''
自 動変速機 や ト ラ ク タ 等湿式 ク ラ ッ チ ま た は 湿式 ブ レ ー キ を有す る 部分の潤滑 に 用 い ら れ る 潤滑油 は、 良好 な摩擦特性, 酸化安定性, 耐腐食性 , 防鍩性を有 し 、 し か も 伝達 ト ル ク が大 き い な ど の性能が要求 さ れ て レヽ る 。 な お 、 こ こ で云 う 摩擦特性 と は静止摩擦係数 と 動摩擦係 数の比を云い、 こ の比が小 さ く 、 し か も 温度や経時 に よ る 変化が小 さ レヽ こ と が要求 さ れ て レヽ る 。  Lubricants used for lubricating parts with wet clutches or wet brakes, such as automatic transmissions and tractors, have good friction characteristics, oxidation stability, and resistance to oxidation. It is required to have performances such as corrosiveness and protection, and large transmission torque. Here, the friction characteristic refers to a ratio between a static friction coefficient and a dynamic friction coefficient, and it is required that the ratio is small and that the change due to temperature and aging is small. It has been reviewed.
従来、 こ の よ う な潤滑油 と し て静止摩擦係数が高 く 、 伝達 ト ル ク の 良好 な も の が知 ら れ て い る 。 し か し な が ら 、 こ の潤滑油 は摩擦特性が充分で な く 、 変速 シ ョ ッ ク が大 き レ、 と レ、 う 欠点 が あ る 。  Conventionally, it has been known that such a lubricating oil has a high static friction coefficient and a good transmission torque. However, this lubricating oil has the disadvantages that the friction characteristics are not sufficient and the speed change shock is large.
特 に 近年、 自 動車の小型化 と F F 車 ( 前輪駆動車 ) の 急増 に よ り 、 自 動変速機 な ど が小型化 さ れ る 傾向 は ま す ま す著 し く な っ て レヽ る 。 こ の よ う な 自 動変速機の小型化 傾向 は 、 変速 シ ョ ッ ク が人体 に よ り 敏感 に 感 じ ら れ る と い う 悪影響を助長する 。 し た がっ て 、 変速シ ョ ッ ク を少 な く し て乗 り 心地を良く す る ため に摩擦特性の一層の向 上を図る こ と が技術課題と な っ ている 。 In particular, in recent years, due to the miniaturization of automobiles and the rapid increase of front-wheel drive (FF) vehicles, the trend of miniaturization of automatic transmissions and the like has become more and more remarkable. This tendency to reduce the size of automatic transmissions is due to the fact that the shifting shock is more sensitive to the human body. Promotes adverse effects. Therefore, the technical challenge is to further improve the friction characteristics in order to reduce the shifting shock and improve the riding comfort.
そ こ で摩擦特性向上の ため に摩擦調整剤を用い た潤滑 油が提案さ れている。 しか し なが ら 、 摩擦調整剤を用い た潤滑油ほ未だ摩擦特性が不充分な う え に摩擦特性が油 温変化 と と も に変化す る こ と 、 お よび長期使用 に よ る油 の劣化 (経時変化) に よ っ て摩擦特性が低下し て し ま う と い う 問題があ っ た。 - し たがっ て、 こ れま で に良好な摩擦特性を有 し、 しか も温度や経時に よ る変化が小さ く 、 かつ伝達 ト ルク の大 き い潤滑油 ほ得 ら れてい ない。  Therefore, lubricating oils using friction modifiers have been proposed to improve the friction characteristics. However, lubricating oils that use friction modifiers still have insufficient friction characteristics, and the friction characteristics change with changes in oil temperature. There was a problem that the friction characteristics were deteriorated due to deterioration (aging). -Therefore, no lubricating oil that has good friction characteristics so far, has little change with temperature and aging, and has a large transmission torque has not been obtained.
本発明 の 目 的 は基油 に 特定の組合せ の化合物 を含有 さ せ る こ と に よ り 、 上記従来の 問題点 を解消 し、 変速 シ ョ ッ ク が少な く 、 しか も伝達 ト ルク が大き く 、 動変 速機等の潤滑に好適 に用い られる潤滑油組成物を提供す る し と に め る 。  The purpose of the present invention is to solve the above-mentioned conventional problems by adding a specific combination of compounds to the base oil, thereby reducing the transmission shock and increasing the transmission torque. In addition, it is intended to provide a lubricating oil composition suitably used for lubrication of dynamic transmissions and the like.

By this treatment, a component that is not desirable in a lubricating oil fraction such as an aromatic component is removed, or a reaction is performed to convert the component into an effective component. At this time, most of sulfur and nitrogen are also removed. To

To improve the stability. If the pour point of the mineral oil obtained here is too high and insufficient, the deep-draining process will continue. This treatment employs a solvent removal method under severe conditions. A zeolite catalyst is used, and the raffin (mainly normanorufin) adsorbed in the pores of the catalyst is used. A method of catalytic hydrogenation is used to remove any that can be selectively decomposed in a hydrogen atmosphere.
