Initial Wet Clutch Frictional Characteristics of ATF/B-CVTF under Low Speed Sliding Conditions 2003-01-1969

The antishudder performance of automatic transmission fluids (ATFs) and belt-drive continuously variable transmission fluids (B-CVTFs) used in automotive transmissions equipped with slip control torque converter lock-up clutch systems is an important issue. These fluids require both initial antishudder performance and antishudder durability, but most researchers have mainly studied antishudder durability.
This paper describes the initial frictional properties-break-in properties-of some commercial ATFs and B-CVTFs using a low velocity friction apparatus (LVFA).
