Description

一种自动变速箱润滑油
技术领域
本发明涉及润滑油，具体是一种自动变速箱润滑油。
背景技术
润滑油是用在各种类型汽车、机械设备上以减少摩擦，保护机械及加工件的液体或半固体润滑剂，主要起润滑、辅助冷却、防锈、清洁、密封和缓冲等作用。只要是应用于两个相对运动的物体之间，而可以减少两物体因接触而产生的磨擦与磨损之功能，即为润滑油。润滑油一般由基础油和添加剂两部分组成。基础油是润滑油的主要成分，决定着润滑油的基本性质，添加剂则可弥补和改善基础油性能方面的不足，赋予某些新的性能，是润滑油的重要组成部分。添加剂是近代高级润滑油的精髓，正确选用合理加入，可改善其物理化学性质，对润滑油赋予新的特殊性能，或加强其原来具有的某种性能，满足更高的要求。根据润滑油要求的质量和性能，对添加剂精心选择，仔细平衡，进行合理调配，是保证润滑油质量的关键。
变速箱油是保持排档***清洁的油类用品，能起到保证变速箱正常工作并延长传动装置寿命的作用。变速箱油基本都能使用于市场上自动变速箱，事实上每一款自动变速箱的设计都有不同的技术要求，即使是同一型号的变速箱配置在不同的车型，其扭矩、重量、转速、结构等都会不同，因此原厂都有其自己指定的专用变速箱油。而不同的变速箱油，正是影响换档品质的原因之一。
