本文介绍了手动变速箱油规格的发展和评定试验,对世界各地区的手动变速箱油的性能规格和评定试验进行了比较。通过对现行的ASTM D5579试验方法和CEC L-66-99试验方法的比较,提出了建立CEC L-66-99试验台架的必要性,该台架将会在手动变速箱油的开发中发挥重要作用。 This article describes the development and qualification tests of manual transmission oil specifications and compares performance specifications and rating tests for manual transmission fluids in various regions of the world. Through the comparison of the current ASTM D5579 test method and the CEC L-66-99 test method, the necessity of establishing a CEC L-66-99 test bench is proposed, which will be used in the development of manual transmission oil Important role.
