摘要
润滑油在无级变速器传动系统中除了发挥润滑冷却的作用外,还要具备合适的动静摩擦因数以及减磨的功效,从而满足传动系统高效长寿命的使用要求,是系统运行不可缺少的材料。随着无级变速器的应用越来越广泛,其传动形式对润滑油的性能要求越来越高。无级变速器传动液对于无级变速器的传动效率和寿命有很大的影响。开发和应用新型自动变速器油及其相应的摩擦特性测试方法,磨损状态评定手段和油品理化性能测试方法及台架试验方法,制定自动变速器油的规格标准,是促进自动变速器发展的关键共性技术。介绍了常见的润滑油基础油和添加剂以及相关测试方法的国内外研究现状,并对无级变速器传动液的未来发展趋势进行了讨论和展望。
In addition to the role of lubrication and cooling in the transmission system of the continuously variable transmission,the lubricating oil must have suitable dynamic and static friction factors and anti-wear effects to meet the requirements of efficient and long-life use of the transmission system,and is an indispensable material for system operation.With the increasing use of continuously variable transmissions,the transmission form requires increasingly higher performance for lubricating oils.Continuously variable transmission fluid(CVTF)has a large impact on the transmission efficiency and life of a continuously variable transmission(CVT).Development and application of new automatic transmission oil and its corresponding friction characteristics test method,wear condition evaluation method and oil physical and chemical performance test method and bench test method,formulate automatic transmission oil specifications,is a key common technology to promote the development of automatic transmission.This paper introduces the domestic and international research status of common lubricant base oils and additives and related test methods.Finally,discusse and forecast the future development trend of CVTF.
