Description
技术领域
本发明涉及作为无级变速器用途而适合的润滑油组合物。
背景技术
近年来，从地球环境问题出发，对于汽车而言，提高燃料消耗也成为重要的课题，与多级式自动变速器（AT：Automatic Transmission）相比效率更高的无级式自动变速器（CVT：Continuously Variable Transmission）的装配比率正在提高。在CVT中，金属制的压带（pushbelt）式为主流，其被搭载于排气量从0.6L至3.5L的大范围的车辆。最近，还搭载了据称效率更高的链式CVT。在这些CVT之中，通过带轮与带之间或者带轮与链之间的摩擦来传导动力，因此为了防止其间的打滑而用较大的力进行按压。带与带轮之间或者链与带轮之间用CVTF进行润滑，但降低其间的按压力导致提高燃料消耗，因此CVTF需要高的金属间摩擦系数。另外，为了进一步提高燃料消耗，大多采用控制内藏有液力变矩器的锁止离合器的打滑的机构。因此，对大多CVTF赋予相对于湿式离合器的摩擦特性。但是，随着CVTF的金属摩擦系数变高，带轮与带之间或者带轮与链之间的振动、噪音时常成为问题。为了抑制该问题，对于CVTF而言，除了高的金属间摩擦系数之外，还期望金属间的摩擦系数-滑动速度特性（以下也称为“金属间μ-V特性”。）优异。
例如，专利文献1中提出了：通过将高碱值与低碱值的碱土金属盐进行组合，并配合酰亚胺化合物和磷化合物，从而提高金属间摩擦系数、提高湿式离合器的摩擦特性。专利文献2中提出了：通过配合碱土金属盐、含硼琥珀酰亚胺、三唑系化合物、（烷基）芳基亚磷酸酯以及酰亚胺系、胺系的摩擦调节剂，从而提高传递扭矩容量，进而提高湿式离合器的耐磨耗性和摩擦特性。专利文献3中提出了：通过磷化合物和琥珀酰亚胺来提高金属间摩擦系数、抑制湿式离合器的堵塞。专利文献4中提出了：将有机酸金属盐与磷化合物、琥珀酰亚胺进行组合，从而提高金属间摩擦系数、抑制湿式离合器的堵塞。另外，作为抑制噪音的相关文献，有专利文献5。具体而言，通过将碱值较低的碱土金属磺酸盐与亚磷酸酯进行组合，并配合包含肌氨酸衍生物、羧酸与胺的反应物产物的摩擦调节剂，从而能够抑制刮擦噪音。

发明内容
发明要解决的课题
上述专利文献1~5中记载的技术均涉及金属间摩擦系数和湿式离合器的摩擦特性，但均未考虑到耐磨耗性。
然而，已知对提高耐磨耗性发挥效果的添加剂存在提高铜熔出性的倾向。铜熔出性高时，难以适用于使用了金属带、链的CVTF。
本发明的目的在于，提供耐磨耗性高、铜熔出性低的润滑油组合物。
用于解决问题的手段
为了解决前述课题，本发明提供以下那样的润滑油组合物。
（1）润滑油组合物，其特征在于，其是在基础油中配合有添加剂的润滑油组合物，前述添加剂为（a）选自碱土金属磺酸盐、碱土金属水杨酸盐和碱土金属酚盐中的至少任一种、（b）含硫的磷化合物、以及（c）噻二唑化合物，该组合物中的前述（c）成分的质量（质量%）与前述（b）成分中的磷元素的质量（质量ppm）之积（（c）×P）为1以上且50以下。
（2）润滑油组合物，其特征在于，在上述润滑油组合物中，前述（a）成分为Ca盐和Mg盐中的至少任一种。
（3）润滑油组合物，其特征在于，在上述润滑油组合物中，前述（b）成分为含硫磷酸酯和含硫亚磷酸酯中的至少任一种。
（4）润滑油组合物，其特征在于，在上述润滑油组合物中，前述（a）成分的基于高氯酸法的碱值为10mgKOH/g以上且500mgKOH/g以下。
（5）润滑油组合物，其特征在于，在上述润滑油组合物中，前述（a）成分中的碱土金属的质量以组合物总量基准计为200质量ppm以上且1000质量ppm以下。
（6）润滑油组合物，其特征在于，在上述润滑油组合物中，前述（b）成分中的磷元素以组合物总量基准计为50质量ppm以上且300质量ppm以下。
（7）润滑油组合物，其特征在于，上述润滑油组合物用于自动变速器。
（8）润滑油组合物，其特征在于，上述润滑油组合物用于无级式自动变速器。
（9）润滑油组合物，其特征在于，在上述润滑油组合物中，前述无级式自动变速器为金属带式或链式。
根据本发明的润滑油组合物，耐磨耗性优异且铜熔出性也低。因此，例如在用作CVTF时，能够较高地保持与金属带CVT、链CVT的动力传达相关的耐磨耗性，另外能够长时间地维持这些特性。
具体实施方式
本发明是在基础油中配合有作为添加剂的（a）选自碱土金属磺酸盐、碱土金属水杨酸盐和碱土金属酚盐中的至少任一种、（b）含硫的磷化合物、以及（c）噻二唑化合物的润滑油组合物（以下，也简称为“本组合物”。）。以下进行详细说明。

〔评价结果〕
如表1所示那样，本发明的润滑油组合物（实施例1~4）是在基础油中配混规定的碱土金属磺酸盐（（a）成分）、含硫的磷化合物（（b）成分）和噻二唑化合物（（c）成分），进而（c）成分的质量（质量%）与（b）成分中的磷元素的质量（质量ppm）之积（（c）×P）为1以上且50以下，因此耐磨耗性优异且铜熔出性也低。
另一方面，比较例1~7的润滑油组合物缺少上述构成中的任一种，因此无法同时满足耐磨耗性和铜熔出性的抑制。
