英文摘要:

      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.
